Document Type and Number:
WIPO Patent Application WO/2024/018990
Kind Code:
A1
Abstract:
[Problem] A vehicle deposit removal device that uses a pumping means operated by the weight of a vehicle to increase the pressure of a cleaning fluid and sprays the cleaning fluid toward the vehicle, wherein the decline in cleaning ability of a long period of time is minimized. [Solution] A pumping means P has an operating chamber A containing a cleaning fluid W. A movable upper wall part 5 of the operating chamber A has a base end part 5A and a free end part 5B, the base end part is supported by a support shaft J extending in the left-right direction, and the free end part 5B swings in the vertical direction as a tire T of the vehicle passes. A seal body S is provided between a fixed wall part C and the movable upper wall part 5, which form the operating chamber A. The seal body S is supported by a support part E provided on the movable upper wall part 5 and is able to move forward and backward toward the fixed wall part C. The seal body S advances toward the fixed wall part C and slides on a wall surface D of the fixed wall part C due to the pressurizing force of the cleaning fluid W in the operating chamber A when the movable upper wall part 5 swings downward and the volume of the operating chamber A decreases.
