Definitions

  • the invention relates to a device provided with a trough for catching leaking liquids.
  • the invention furthermore relates to a parking plate for a vehicle provided with such a device.
  • a device for catching leaking liquids is known from FR-A-2 659 096.
  • Vehicles for example cars or buses, as well as machines often leak oily and/or greasy liquids, which are absorbed by the ground on which said vehicles and/or machines stand, which results in contamination of said ground.
  • the object of the invention is to provide a device for catching leakage liquids with which the leakage liquids are caught in a reliable manner without any contamination of the soil.
  • the device is provided with a grid detachably connected with said trough, by means of which the trough can be closed, and a water-repellent, leakage liquid-absorbing material positioned between said grid and said trough.
  • the device is installed in the ground at the location of a liquid-leaking machine or in the ground of a parking space for a vehicle.
  • the leakage liquid falls through the grid on to the absorbent material, which absorbs the liquids which are harmful to the environment, for example oily and greasy liquids, and which repels water.
  • the presence of the trough prevents the contaminated liquid from finding its way into the ground.
  • the absorbent material is saturated, it is replaced by clean absorbent material and the contaminated absorbent material is discharged to a processing company.
  • all contaminating liquids are concentrated in the absorbent material and only a relatively small volume needs to be transported to a processing company.
  • the device according to the invention makes it possible to prevent contamination of the soil and the ground water by the leakage liquids and to catch the leakage liquids in a reliable and safe manner.
  • One embodiment of a device according to the invention is characterized in that the absorbent material is present in the trough in the form of a cloth.
  • Another embodiment of a device according to the invention is characterized in that said trough is provided with a bottom, which comprises at least one water discharge channel.
  • the clean water repelled by the absorbent material is discharged from the trough through the water discharge channel. Also rain water is discharged through the water discharge channel.
  • Yet another embodiment according to the invention is characterized in that said water discharge channel is located in a relatively elevated part of said bottom.
  • the water which has flown through the absorbent material should nevertheless contain any residual leakage liquids, such as oils or greases, said residual leakage liquids will tend to float on the water under the absorbent material.
  • the water will not be able to leave the trough before the water level inside the trough has risen to a level where the water can flow out through the elevated water discharge channel.
  • the residual leakage liquids present on the water will likewise rise.
  • the leakage liquids are pressed against the bottom side of the absorbent material and caught by the absorbent material as yet.
  • Another embodiment according to the invention is characterized in that said water discharge channel is located in a relatively lower part of said bottom.
  • Yet another embodiment of the device according to the invention is characterized in that said water discharge channel is located in the centre of the trough.
  • Yet another embodiment of a device according to the invention is characterized in that water discharge channels are located on either side of the trough.
  • Yet another embodiment of a device according to the invention is characterized in that said water discharge channel is provided with a powdered or granular absorbent material.
  • the liquid inside the trough will flow to the water discharge channel, where the water leaves the trough via the water discharge channel and harmful substances are caught by the absorbent material. Because of the powdered or granular form of the absorbent material the entire water discharge channel can be filled with absorbent material and no liquid can leave the trough without having been in contact with said absorbent material.
  • Yet another embodiment of a device according to the invention is characterized in that the grid can be locked to the trough.
  • the grid can only be removed by authorized personnel in order for the contaminated absorbent material to be replaced by clean absorbent material. Removal of the grid by unauthorized persons is made impossible, as a result of which unsafe situations of a trough lying open cannot occur when the device is for example being used as a parking space.
  • the invention furthermore relates to a parking plate for a vehicle, whereby the soil pollution problems of the known parking spaces are prevented.
  • This objective is achieved with a parking plate for a vehicle, which parking plate is provided with at least one device according to the invention.
  • the entire parking plate may be provided with a device according to the invention. It is more effective, however, to provide the parking plate with a device according to the invention only in those places where a liquid-leaking part of a vehicle to be parked is expected to be present. This will be near the engine and near the exhaust of the vehicle.
  • One embodiment of the parking plate according to the invention is characterized in that the parking space is provided with at least one plate supporting the vehicle to be parked, which plate comprises the device for catching the leakage liquids.
  • the plate and the device according to the invention together form a unit which can be provided at a random location so as to create a parking space.
  • FIG. 1 shows an embodiment of a parking plate according to the invention, which is provided with two flat, mirror-symmetrically disposed identical concrete plates 2, which are each provided with a device 3 for catching leakage liquids according to the invention.
  • the position of the devices 3 with respect to the parking plate has been selected such that the devices 3 are located at those places where a vehicle parked on the parking plate 1 is expected to leak harmful liquids, such as oils and/or greases. Usually this will be near the exhaust and near the engine of the vehicle.
  • Each device 3 is provided with a metal grid 4, which is disposed in a lowered portion of the plate 2, in such a manner that a substantially flat appearance of the plate is retained.
  • the grid 4 closes a trough containing a water-repellent, leakage liquid-absorbing material. This will be explained in more detail hereafter.
  • Figure 2 is a clear view of the grid 4 of the device 3 shown in Figure 1.
  • Figure 3 shows a lock means 5 provided in the concrete plate 2, with which the grid 4 can be locked to the concrete plate in order to prevent the grid 4 and/or the absorbent material from being undesirably removed.
  • the lock means 5 comprises a pin 6, which is capable of sliding movement within a slot provided in the grid 4. Rotation of the lock means 5 in the direction of the arrow 8 will cause the pin 6 to move out of the slot 7, after which the grid 4 can be removed so as to replace the absorbent material.
  • FIG 4 is a cross-sectional view along the line IV-IV in Figure 1, wherein the grid 4 has been left out for easy reference.
  • the parking plate 1 comprises the concrete plate 2 and a trough 9 of plastic material, which is positioned in a lowered portion of the concrete plate 2.
  • the thin-walled plastic trough 9 is provided with a bottom plate 10, which slopes down from the centre towards the sides of the trough 9, as a result of which leakage liquids falling into the trough will flow to the sides of the trough.
  • the bottom plate 10 of the trough 9 is provided with water discharge channels 11, which are connected to discharge channels 12 in the concrete plate 2. Liquid can only leave the trough via the discharge channels 11, 12.
  • a cloth 13 of a water-repellent, leakage liquid-absorbing material is located inside the trough 9, and a powdered absorbent material is located within the discharge channels 11, 12.
  • Leakage liquids from a parked vehicle fall through the grid 4 on to the absorbent cloth 13.
  • Water is repelled by the cloth 13 and separated from the harmful oily and greasy constituents of the leakage liquids. Then the water flows to the discharge channels 11, 12 under the influence of gravity, where it disappears through the powdered or granular absorbent material 14 into the ground 15.
  • the powdered or granular material 14 provides an extra filtration of the water already purified by the cloth 13, as a result of which any residual harmful liquids are removed as yet.
  • the cloth 13 may be made of an absorbent material, such as OIL-DRI-MARINE (trademark), which is supplied by Anlag International B.V. of Lunteren.
  • the powder 14 may be OIL-DRI (trademark) CHEM-SORB powder, for example, which is supplied by the same company.
  • This OIL-DRI (trademark) absorbent material comprises polypropylene. the absorbent materials referred to above are also supplied by Bosco B.V. of Sneek under other brand names.
  • Figure 5 is a side view of a car 16, which is parked on a parking plate 1 according to the invention.
  • the car 16 comprises an engine 17 and an exhaust 18, from which harmful liquids 19 may leak.
  • the liquids 19 are caught by the devices 3 positioned under the engine 17 and the exhaust 18.
  • FIG. 6 is a cut-away view of a device 3 according to the invention.
  • the trough 9 is made of liquid-tight concrete, whereby the bottom 10 of the trough 9 slopes down towards the edges. Near the edges, which are reinforced by means of metal sections 20, elongated discharge channels 12 are provided in the concrete plate 9.
  • the metal sections 20 are provided with corresponding discharge channels 11.
  • Absorbent cloths 13 are provided in the trough 9 and in the discharge channels 12, after which the trough 9 is closed by means of the grid 4.
  • the leakage liquids flow in the direction of the arrow 23 through the grid 4 and the cloths 13 to the discharge channels 12, where the liquids purified by the absorbent cloths 13 disappear into the ground 15 located under the trough 9.
  • Figures 7 - 9 show another embodiment of a device 3 according to the invention, wherein the trough 9 made of metal plates is provided with a water discharge channel 11 located in the centre of the trough 9, which is positioned lower than the edges of the trough 9.
  • Figure 8 is a cross-sectional view of the device 3, along the line VIII-VIII in Figure 7, in which the bottom plate 10 sloping down from the edges towards the centre can be clearly distinguished.
  • the edges of the trough 9 are made up of metal sections 20, which are positioned on edges of the concrete plate 2.
  • Figure 9 shows a detail IX of the cross-section shown in Figure 7.
  • the trough 9 comprises a metal bottom plate 10 sloping down towards the centre, metal sections 20 and metal flanges 21, by means of which the bottom plate 10 and the sections are interconnected.
  • a leakage liquid-absorbing cloth 13, which catches liquids leaking through the grid 4, is present on the bottom plate 10.
  • the grid 4 is kept spaced from the cloth 13 by means of bent-over edges 22.
  • FIGS 10 and 11 show another embodiment of a parking plate 1 and a trough 9 respectively for a such a parking plate 1.
  • the parking plate 1 is provided with a metal trough 9, which is mounted in a concrete plate 2.
  • the trough 9 is provided with four parallel gutters 25, which are separated from each other by upright edges 26.
  • the upper sides 27 of the edges 26 extend parallel to an edge 28 of the trough 9.
  • Each gutter 25 comprises two bottom surfaces 29 sloping upwards from the edges 28 to the centre of the gutter 25.
  • Each gutter 25 is in its centre provided with a water discharge channel 11, which, as a result the bottom surfaces 29 sloping upwards towards the centre, is located at the highest point of the gutter 25.
  • Absorbent cloths 13 are positioned in the four gutters 25, said cloths at least abutting against edges 30 of the discharge channels 11.
  • the trough 9 is furthermore provided with an angle section 31, a supporting structure 32 positioned therein and a cover grid 4 positioned thereon.
  • the leakage liquids are caught by the absorbent cloths 13 and the purified water flows through the cloths 13 into the gutters 25. If the water should nevertheless contain any residual leakage liquids, the residual leakage liquids are caught via the bottom sides of the cloths 13 directed towards the gutters 25, since the water inside the gutters 25 will rise until the water level has reached the level of the discharge channel 11.
  • the leakage liquids floating on the water are thereby pressed against the bottom sides of the cloths 13 and absorbed by the cloths as yet.
  • the parking plate 1 is dimensioned 5 x 2.5 m, for example, with a thickness of 15 cm.
  • the size of the grid will for example be 1 x 1.25 m. When the parking plate is used for lorries or buses, the dimensions will have to be larger.
  • the grid 4 may be made of metal or plastic material.
  • the grid has a porosity of 20%, for example, and apertures of 6 x 20 mm.
  • the absorbent material may for example be made of polypropylene, sheepskin or other water-repellent materials.
  • the device according to the invention is also suitable for catching leakage liquids from machines.
