ABSTRACT:
FIELD OF THE INVENTION
The present invention is concerned with a receptacle for use for heavy duty equipment washing.
BACKGROUND OF THE INVENTION
Commercial car and truck washing has become a focus of public concern and government regulation recently over the disposal of used wash water into municipal sewer systems or directly into the ground. The combination of oil, water, soap, dirt and other chemicals in the used wash water can be harmful to the environment if allowed to drain into a sewer or seep into the earth.
It is now known to have mobile washers for washing cars, trucks and any other type of machinery on site. These washers are equipped with water treatment systems and are well described in U.S. Pat. No. 5,669.982. Typically the trucks are self-sufficient in that they contain all the equipment needed for the cleaning purposes, for instance, water reservoir, soap injector, sprayers, hoses, a nacelle or carriage and a drainage receptacle. During the washing, the used water is drained onto the drainage receptacle and forwarded back inside the washer in order to be recycled.
U.S. Pat. No. 5,423,339 is concerned with an apparatus for treating articles with wash water. This patent discloses the use of a wash pad comprising three unconnected portions. However, this patent does not disclose the use of longitudinal cover strips for fitting over the wheels of a vehicle, so as to further guide the water collected on the wheels of the vehicle onto the wash pads on the ground. The wash pads that are described in this patent only include a centre portion and side portions. No pads are provided for covering the wheels of the vehicle. Hence, the water that is collected on the wheels will directly seep in the ground.
SUMMARY OF THE INVENTION
It is an object of the present invention to provide a drainage receptacle that is designed to maximize the recycling of the water used for washing the vehicle.
It is also an object of the present invention to provide a drainage receptacle for use in the washing of heavy-duty vehicles.
It is another object of the present invention to provide a drainage receptacle that is designed to reduce the risk of tear by heavy-duty vehicles during installation of same.
More precisely, the present invention is concerned with a drainage receptacle for collecting used water during washing of a vehicle, the vehicle having at least one pair of side wheels, the drainage receptacle comprising:
individual substantially rectangular elongated ground strips for installation in parallel and spaced apart to each other on the ground so to form there between a passage for each pair of side wheels of the vehicle, each ground strip being made of an impermeable material and having a bottom sheet and four side walls for retaining used water therein, and
individual substantially rectangular elongated cover strips for installation over each pair of side wheels respectively thereby allowing water to drain over the cover strips and onto the ground strips.
The present invention is also concerned with a drainage receptacle kit and a method for using the drainage receptacle of the present invention.
An advantage of the drainage receptacle of the present invention, is that it is now possible to execute on-site washing of heavy-duty truck such as a tractor, tracked vehicles, forest machinery and the like without running the risk of tearing the receptacle.
The drainage receptacle of the present invention also maximizes the recycling of the waste water resulting from the washing of the equipment.
