Description

[Detailed description of the invention] Conventionally, a battery case that houses the air battery that is the power source for a light buoy has a fixing device that has several tightening bolts to fix the battery inside the battery case, and a lid that is watertight. It has several tightening bolts to secure it in place, and inspecting and replacing the battery requires opening and tightening many bolts on a moving light buoy at sea, which is dangerous. It was difficult work, especially in the winter.

The present invention relates to an improvement of the battery case of a light buoy, which allows the opening and tightening of the battery case lid and the opening and tightening of the battery fixing device to be performed by the simple operation of opening and tightening a single nut. .

Next, embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 is a partially cutaway front view of a light buoy, where 2 is a buoyant body, 1 is a battery case containing batteries, and buoyant body 2
The battery case and the deck are fixed by welding or the like. The buoyant body is filled with closed-cell resin. Furthermore, a tower 3 is erected on the deck, and a lamp 4 is provided at its upper end.

FIG. 2 is a cutaway front view of the battery case 1, in which a battery 6 is placed on the bottom plate 7 of the battery case, and is prevented from moving laterally by a detent 9. 10 is a ventilation pipe provided through the side wall of the battery case, 11 is a side wall 8
A pair of left and right inverted L-shaped receiving metal fittings are provided at a position higher than the battery on the inner surface of the battery, and are fixed symmetrically with the left and right directions opposite, and an elbow plate 12 is attached to the upper surface of the metal fittings for reinforcement. Reference numeral 13 is a beam having both ends 13' abutting and locking on the receiving metal fittings 11 and having a hard hole 14 in the center through which the center bolt 16 is inserted. 15 is pivotally supported, and the upper end 16' is cornered so that a wrench can be hung thereon.The lid 19 is inserted through the lid 19, and a nut 18 is screwed into the lid 18 from above.

The pair of presser arms 15 are curved in an L-shape on the side, and one end is pivotally supported on the center bolt so that the curved corner 15'' is located on the upper side, and the tip 15' is provided so as to be in contact with the top surface of the battery. The presser arm 15 is urged by the spring 15 so that the tip 15' rotates upward, and the rotation is stopped by the stopper 16'' of the center bolt 16. The biasing force of the spring is such that it can withstand even if the weight of the beam is applied to the corner 15'' of the presser arm 15.

A rotation stopper plate 1 is installed on the lower surface of the beam to prevent the presser arm from rotating with the center bolt and coming off the lower surface of the beam.
7 are provided hanging down on both sides of the presser arm. 1
Reference numeral 9 denotes a lid of the battery case, which is pivotally supported so as to be openable and closable by connecting a hinge fitting 20 fixed to the right end in the drawing and a hinge fitting 20' fixed to the upper part of the side wall with a shaft 21. At least one of the shaft holes of the hinge fitting is an elongated hole for tightening the lid.
An insertion hole 22 through which the center bolt 16 is inserted is bored in the center of the lid 19. A watertight ring-shaped gasket 23 is installed in a groove 24 on the periphery of the lower surface of the lid 19. Further, a washer 25 having a hole continuous with an insertion hole 22 threaded on the outer periphery is fixed to the upper center surface of the lid 19, and a cap 26 is screwed onto the washer to cover the head of the center bolt 16. It is designed to be watertight.

Next, the case where a battery is attached to the battery case of the present invention will be explained. With the lid 19 open, the nut 18 is screwed onto the center bolt so that there is some clearance between the nut 18 and the lid. Lower the battery 6 into the battery case and store it inside the detent 9. Next, the lid 19 is closed so that both ends 13' of the beam 13 pass over the receiving fitting 11. Next, from the position of the beam indicated by the dashed-dotted line in the plan view of FIG. direction. In this state, the presser arm 15 of the center bolt 16 has a slight gap between its tip 15' and the upper surface of the seat plate 27 placed on the battery, as shown by the dashed line in FIG.
The beam rests on the corner 15'' of the presser arm due to its own weight, and a slight gap is maintained between the upper surface of both ends 13' of the beam and the lower surface of the flange of the bracket 11. Next, tighten the nut 18. , the center bolt 16 rises together with the beam 13, and the upper surfaces of both ends 13' of the beam come into contact with the flanges of the bracket 11, and the beam stops rising.As the nut 18 is further tightened, the center bolt 16 rises, The shaft support of the presser arm rises, but the corner 15'' of the presser arm comes into contact with the lower surface of the beam and cannot rise, and the presser arm 15 overcomes the biasing force of the spring 15 and rotates, and the tip 15' descends. , seat plate 27 above the battery
reaches the top of the When the nut 18 is further tightened, part of the tightening force of the nut 18 becomes a pressing force against the battery, thereby pressing and fixing the battery. That is, by tightening the nut 18, the battery is pressed and fixed, and at the same time, the lid is also tightened and fixed to the battery case.

Next, when opening the lid and releasing the battery, the process is completely reversed; by loosening the nut, the pressing force of the presser arm is released, the presser arm 15 rotates under the biasing force of the spring 15, and the tip 15' is seated. After leaving the top surface of the plate 27, the presser arm stops rotating at the stopper 16'' of the center bolt, and both ends 13' of the beam are lowered and disengaged from the bracket 11, so turn the beam 13 horizontally a little. Avoid the bracket 11 and open the lid 19.

As described above, by turning one nut (18) of the center bolt, the battery can be press-fixed, the lid can be tightened watertight, or released, making it almost a one-touch operation and eliminating work on unstable light buoys at sea. This will save you a lot of labor.

Figure 5 shows another method of attaching the light buoy to the battery case, in which the bottom plate of the battery case is extended into a flange shape and fastened with bolts and nuts to the stand provided on the deck of the buoyant body. show. As shown in the above two examples, the battery case can be standardized as a separate case independent of the light floating specimen, which will also help improve productivity and reduce costs.

Furthermore, if the lid 19 is made of a rotating body with an upward convexity, it will be strong and strong, and can be made of synthetic resin, which will reduce the weight and cost.
