Description

Stationary shelter for storing at least one electrical energy storage unit.

GENERAL TECHNICAL AREA

The invention lies in the field of autonomous and stationary electrical installations, that is to say fixed installations, which couple means of energy production, such as solar panels or wind turbines for example, with units. for storing the electrical energy thus produced.

The invention relates more particularly to a stationary shelter for storing at least one such energy storage unit, this shelter containing at least one element for receiving said unit and being equipped with a device for lifting and handling this unit.

STATE OF THE ART

The aforementioned electrical installations are intended to be installed in remote areas, difficult to access, for example but not exclusively in Africa.

Shelters, known by the English name of shelters, make it possible to house not only at least one energy storage unit, but also various devices ensuring the electronic management of their operation and their security.

Stationary shelters for storing at least one energy storage unit are thus known, which comprise at least one location for receiving said unit, preferably several, superimposed and / or juxtaposed.

In practice, the introduction of energy storage units in the stationary shelter is carried out as follows. Said units are transported in cases. A transporter unloads said boxes near the shelter. The boxes are opened, then the operator using a manual or motorized forklift inserts the units into the stationary shelter.

However, this operation requires providing around the stationary shelter a loading area suitable for the forklift, in terms of leveling of the ground and the nature thereof.

When the storage shelter is installed in areas of difficult access, it can be on any type of terrain, for example uneven, stony, it can even be on the ground at a height different from that to which the forklift. In these different cases, and also taking into account the weather conditions, the Applicant has found that loading and unloading energy storage units in and out of the storage shelter can be dangerous and very complex.

In addition, it must be taken into account that these energy storage units can be quite heavy, for example of the order of 300 kg to 400 kg, or even 500 kg.

PRESENTATION OF THE INVENTION

The invention therefore aims to solve the aforementioned drawbacks of the prior art and in particular to allow loading or unloading of energy storage units in and out of the shelter, which is secure for the operator , without risk of damage to this unit or this shelter, even if the terrain around the shelter does not allow a lift truck to be brought there.

DETAILED DESCRIPTION

Referring to Figure 1, one can see a stationary storage shelter 1 of at least one electrical energy storage unit U, this shelter being equipped with a lifting and handling device 2 of said unit.

Without being limiting, it will be noted that the electrical energy storage units U referred to in the present application are preferably electrical energy storage batteries, of the LMP® type (for Lithium Metal Polymer) or of the type lithium ions, whose weight is less than 500 kg, preferably of the order of 300 kg to 400 kg.

This shelter 1 is intended, inter alia, to protect the units U from bad weather and to offer a stable climatic enclosure.

The storage shelter 1 is said to be stationary, in the sense that it rests on the ground and is not carried on a mobile vehicle.

The stationary shelter 1 is a structure whose general shape is preferably that of a cubic or rectangular parallelepiped.

Preferably, this structure comprises four vertical uprights, called rear uprights 101, for the two located on either side of an access opening 11 inside the shelter 1, and said front uprights 102, for the two others.

By convention, we denote before AV, the side of shelter 1 through which an operator can penetrate, and rear AR, the opposite side, which is also that by which U units can be introduced into or extracted from the shelter 1.

The rear 101 and front 102 uprights are also linked together in pairs by an upper beam 121 and a lower beam 122.

In addition, the rear uprights 101 are interconnected by a rear upper cross member 131 and a rear lower cross member 132, while the front uprights 102 are connected together by a front upper cross member 141 and a front lower cross member not visible in the figures. .

The shelter 1 also has an upper wall 15, two side walls 16 of which only one is visible in the figures, a bottom and a front wall not visible in the figures. Finally, preferably, the access opening 11 is closed by at least one door, here two hinged doors referenced 17.

The various walls of the shelter 1 together delimit an enclosure, inside of which a support structure 3 is arranged, intended to receive at least one electrical energy storage unit U.

This support structure 3 is preferably secured to the shelter 1 and it is generally fixed on the inner face of the walls thereof.

According to a first embodiment, this support structure 3 comprises at least one sliding element 30 for receiving an electrical energy storage unit U and, preferably, several of these sliding elements, superimposed on each other, as can be seen in the figures, even juxtaposed, in alternative embodiments not shown.

In its simplest embodiment, shown in Figures 1 and 3 to 8, this sliding element 30 may be in the form of two slides, arranged at the same height, one opposite the other, each slide carrying a support bracket for said energy storage unit U. These slides are shaped to receive said unit from above.

In more elaborate embodiments, this sliding element 30 can be in the form of a cradle or a drawer, or any other device for receiving a U unit.

Whatever the embodiment of the sliding element 30, it can slide through the access opening 11 between a retracted position inside the shelter 1, which is that shown for example in the upper or lower parts of Figure 1, and an extended position outside the shelter 1, which is that shown for the unit U placed in the center in Figure 1. In addition, this sliding element 30 is also shaped so that the unit U can be inserted into it from the top or be taken out from the top, that is to say vertically.

According to a second embodiment, shown in FIG. 2, the support structure 3 comprises at least one fixed receiving element 31, preferably several receiving elements 31 superimposed, or juxtaposed in variants not shown. Each receiving element 31 comprises for example two parallel support brackets 310, arranged so that their horizontal wings are located at the same height, one opposite the other and spaced from each other by a distance corresponding at least to the width of the electrical energy storage unit U.

These two brackets can also be replaced, for example, by a shelf or by fixed guide rails in which slide a rolling member (such as a shoe or a wheel) integral with lateral fins of the U unit.

The U unit is inserted into the receiving element 31 by horizontal sliding on the brackets 310, from the rear AR of the shelter 1 towards the AV and is extracted therefrom in a reverse movement.

Advantageously, the brackets 310 can be coated at least in part with a layer of material facilitating the sliding of the unit U, such as a polymeric material with low friction surface, for example polytetrafluoroethylene (or PTFE). This layer of material can also be placed under the lateral fins of the U unit.

The lifting and handling device 2 is assembled with the outer surface of the stationary shelter 1 by assembly means. By "exterior surface" is meant the upper wall 15, a side wall 16, an upper spar 121, an upper cross member 131, 141, a vertical upright 101, 102 or a corner of the parallelepiped shelter 1.

As will be seen later, these assembly means are preferably removable, that is to say that it is possible to separate the lifting device 2 from the shelter 1 without damaging them.

However, they could also be non-removable, i.e. permanent.

Preferably, and as can be seen for example in FIG. 1, the lifting and handling device 2 comprises a jib 21, a hoist 22 (or a winch) and a hooking tool 23, 25 of the unit for storing electrical energy U.

The hoist or winch 22 can be manual or motorized.

The attachment tool can for example be a lifting frame 23, such as that shown in FIG. 10.

Such a lifting frame 23 preferably has at its four corners 231, chains or hooks or rods 232 making it possible to hang four points of an electrical energy storage unit U and to move it vertically while maintaining it horizontally. This frame 23 is also provided in its center with a fixing point 233 of the hoist 22, such as a ring.

The attachment tool can also be a fork 25 provided with two horizontal parallel branches 251 capable of being slid under the unit U and provided at its upper part with a fixing point 252 (such as a hook or ring ) audit hoist or winch 22.

The frame 23 or the fork 25 are further shaped to resist the displacement of heavy loads, preferably less than about 500 kg, the units U generally having weights between 300 kg and 400 kg, as mentioned above.

It will be noted that the lifting frame 23 is used when the receiving element is sliding (element 30) and that the loading / unloading of the unit U is carried out from above this element 30. Conversely, the fork 25 is used when the receiving element is fixed (element 31) and the loading / unloading of the unit U is carried out from the rear and horizontally (sliding on the brackets 310).

First embodiments of the bracket 21, according to different configurations, will now be described in conjunction with FIGS. 1 to 6 and 12.

In FIG. 2, the bracket 21 comprises a vertical upright 211, on which is fixed a perpendicular horizontal crosspiece 212, these two parts possibly being connected by an oblique support bar 213.

The hoist or winch 22 is hooked to the free end 214 of the cross member 212, this end being provided for example with a hook or lifting ring 215.

The base 217 of the bracket (that is to say more precisely the lower end of the vertical post 211 visible in FIG. 12) is assembled with a point on the outside surface of the shelter 1.

Preferably, this assembly is carried out using a barrel 18, that is to say a hollow structure, of a shape complementary to that of the base 217 of the bracket, for example a cylindrical or oblong shape .

The barrel 18 thus constitutes an exemplary embodiment of the means for assembling the bracket 21 with the shelter 1.

In the case where the assembly means are removable, the base 217 of the stem 21 is simply inserted inside the barrel 18, the length thereof and the depth of the barrel 18 being dimensioned so that the stem 21 does not leave the barrel when a load (unit U) is attached to the hoist 22 or to the frame 23.

Such removable assembly means allow the user to move the lifting and handling device 2 and store it, for example inside the shelter 1 before and after its use. In addition, this makes it possible to move the shelter 1, for example to transport it to its place of installation, without the device 2 being in place and hindering the handling of the shelter 1.

In the case where the assembly means are permanent, the base 217 of the bracket 21 is permanently fixed to the shelter 1, for example welded into the barrel 18.

The bracket 21 can be statically or pivotally mounted around its vertical upright 211 (see for example in FIG. 2 the double arrow F which represents the angular movement of said bracket). In the latter case, the base of the bracket 21 can for example pivot inside the barrel 18.

The height of the upright 211 is adapted so as to be able to allow the loading or unloading of the electrical energy storage unit U which is located at the highest position inside the shelter 1.

The height of the upright 211 is also adapted to the positioning of the stem. Thus, when the bracket 21 is mounted on the upper part of the shelter 1, as shown in Figures 1 to 3, its height will be less than when the bracket is mounted on a side wall of the shelter 1, as shown in figure 4.

Furthermore, the length of the cross member 212 is adapted to the radius of action which it is desired to be able to have around the shelter 1 and also to the position of the lifting device 2 on the shelter 1. Thus, for example, when the bracket 21 is positioned forward, as can be seen in Figure 3, the cross member 212 may be shorter than when the bracket is placed in the center of the upper part of shelter 1, as can be seen on Figure 2.

In all cases, the lifting and handling device 2 has sufficient mechanical strength to support a heavy load, preferably less than 500 kg.

The barrel 18 can be formed directly in the walls of the shelter 1, for example in the thickness of the upper wall 15 of the shelter 1, at all points thereof, and for example in its center, as shown in figure 2.

The barrel 18 can also be formed in one of the upper longitudinal members 121 or in one of the rear rear crossmembers 131 or front 141 (see FIG. 3).

Finally, as can be seen in FIG. 1, the barrel 18 can also be formed at the level of the upper end of one of the vertical uprights, preferably one of the rear uprights 101, the upper ends of these uprights vertical being fitted with a corner 6.

Such a corner is for example a so-called ISO corner, since it meets an ISO standard. It is shown in Figure 9.

As shown in FIG. 6, the barrel 18 can also be fixed in the center of a force recovery cross 7, this cross 7 extending over at least part of the upper face 15 of the shelter 1 and its four ends being assembled in a removable or permanent manner in the upper wall 15.

H

According to yet another alternative embodiment shown in FIG. 5, the barrel 18 is fixed on a lateral support, the latter being fixed for example at its two ends to the upper corners of the shelter 1. In this configuration, the bracket 21 rests then only against the side wall 16 of the shelter 1 and the side support 8 is suspended.

As can be seen in Figure 4, the barrel 18 can also be fixed directly to the side wall 16 of the shelter 1 at any point thereof, for example towards the rear and substantially at mid-height. Reinforcement means for the wall 16 of the shelter 1 can be provided to guarantee that the fixing of this barrel 18 will not cause deformation of said wall 16.

Second embodiments of the lifting and handling device 2, according to two other configurations will now be described in connection with Figures 7 and 8. In these configurations, the jib is also equipped with a hoist or winch 22 and an attachment tool 23 or 25 although the latter are not shown in these figures.

In the variant of FIG. 7, the bracket is then referenced 24. It comprises a horizontal support 241, such as a bar, the two ends of which are curved or folded and assembled with the upper wall 15 of the shelter 1, for example by the removable or permanent assembly means described above (barrel for receiving said ends). This horizontal bar 241 extends at a certain distance (height) from the upper wall 15 of the shelter

1.

In the variant of FIG. 7, the bracket 24 also includes a straight longitudinal bar 242, the fixed (or lower) end 243 of which is assembled with the upper wall 15 of the shelter 1 by the removable or permanent assembly means , such as a barrel 18, the free (or upper) end 244 of which supports a hook or ring for fixing the winch or hoist 22 (not visible in the figure) and the middle part of which is fixed perpendicular to said horizontal support 241, so that this bar 242 is inclined relative to the horizontal.

The variant of FIG. 8 differs from that of FIG. 7 in that the bracket which is then referenced 24 'comprises a longitudinal bar 245 in L, the base of the vertical branch 246 of which is received in a barrel 18 and the branch of which 247 horizontal rests in its middle part on the support 241. The free end of the horizontal branch 247 also carries a ring or hook for supporting the hoist or winch 22. The bar 245 is pivotally mounted around the vertical branch 246 so that 'It can pivot in a horizontal plane, the branch 245 resting and sliding on the support 241.

According to an alternative embodiment shown in Figure 12, the free end 214 of the cross member 212 supports a movable element in translation or sliding carriage 216. Its movement can be manual or motorized. The hoist or winch 22 is fixed on this element 216. This carriage 216 provides a degree of freedom in the horizontal direction (arrows G) and allows horizontal movement of the unit U. This carriage is particularly advantageous when combined with the fork 25, because it allows the unit U to be loaded by sliding in a fixed receiving element 31. This carriage 216, combined with the hoist or winch 22 which allows vertical movement (arrows H), makes it possible to enlarge the field of action of the lifting and handling device 2.

This carriage 216 could be replaced by a telescopic portion of the cross member 212.

This carriage 216 or this telescopic portion could also be provided at the end of the longitudinal bars 242, 247 of the brackets 24, 24 ’.

The method for charging an electrical energy storage unit U inside the shelter 1 is as follows.

The operator deposits the box C (Figures 2 and 3) containing the unit U using appropriate tools in the unloading area located near the shelter 1. He opens the box C and stows the attachment tool 23 or 25 to the unit U. It then moves the jib if necessary so as to bring the hoist or winch 22 above the tool 23, 25 and hooks the hoist or winch to this tool.

Depending on the different embodiments of the invention, the operator may or may not move the bracket, actuate the carriage 216 and the hoist 22 and bring the unit U close to the receiving element 30, 31. If the support is sliding, it comes out of the shelter 1, possibly locks the support 30 in the extended position, deposits the electrical energy storage unit U inside from above, then detaches the hanging tool 23, 25, then brings the sliding element 30 and the unit U into the retracted position inside the shelter 1.

If it is a fixed receiving support 31, it slides the unit U on the brackets 310 using the fork 25.

One person is enough to perform this maneuver. From a safety point of view, there is no longer any risk linked to the state of the loading area which extends around the shelter.
