Description

[Detailed Description of the Invention] A. Purpose of the Invention (Field of Industrial Application) The present invention relates to a mobile vehicle lower part cleaning device for cleaning the lower part of a vehicle, particularly a vehicle engaged in snow and ice work on a highway.

(Prior Art) To wash vehicles that have returned from work, manual work using pressurized water from a hand gun is relied upon.

(Problems to be solved by the invention) Anti-freezing agents (sodium chloride, etc.) adhere to vehicles engaged in snow and ice work in the winter, resulting in significant corrosion due to rust. Therefore, every time a vehicle returns to base, it is cleaned with pressurized water using a hand gun. However, since a large amount of antifreeze adheres to the underside of the vehicle, cleaning the antifreeze agent is extremely difficult, and combined with the adverse conditions of working in cold air, the work is extremely harsh.

The present invention is intended to automatically clean the underside of a vehicle, to economically clean it according to large and small vehicle types, and to reduce the distance traveled by the vehicle during cleaning.

B. Structure of the invention (Means for solving the problems) The present invention provides water collection grooves in multiple rows in a direction perpendicular to the vehicle entrance/exit direction in approximately half of the road surface area for large vehicles on the vehicle entrance/exit side. is connected to a drainage ditch at one end, and a water supply pipe for each system is inserted into these ditches, and a nozzle is installed in the water supply pipe in the water collection ditch, and a large or small pipe is installed near the entrance of the road surface area. A push button switch is provided for inputting the signal, and a plurality of sensors are provided at intervals in the longitudinal direction in relation to the range,
These sensors are connected to the switch and the water supply source by cables, and the sensor instructed by the large or small signal of the switch detects the vehicle position and supplies water to the water supply pipe of a predetermined system or stops the water supply. It is characterized by

(Operation) When the worker returns from work, he presses the switch to select large or small size. This determines which sensors are activated, and determines the active area of the nozzle of the cleaning device, such as at both ends for a large device and at the middle for a small device. When a large vehicle first enters the storage area, a sensor at the entry end detects this and the nozzles in the rows at both ends begin spraying cleaning water. As the vehicle enters the storage road surface area, the underside of the vehicle is washed across the water film surface from the leading or trailing end side to the opposite side. Then, it straddles the nozzle row that is at rest and is washed with water from the nozzle row further back. A sensor detects when a vehicle is within range and shuts off the water supply. In the case of large vehicles, sufficient cleaning cannot be done in one go, so the water supply will be stopped when this sensor counts twice, that is, when the vehicle has moved backwards and forwards once from the depths of the vehicle. You can also do it. In this case, the vehicle only needs to move half the length of the vehicle.

In addition, in the case of small size, the sensor in the middle is activated,
It senses the approach of a vehicle and cleans it, and senses its passing and stops. If it is small, a single sensor may be sufficient as long as its entire length is included in the sensing angle of one sensor.

(Example) 1 is a road surface area that can accommodate large vehicles, 2 is the entrance/exit side of vehicles to this area 1, 3, 4, and 5 are water collection grooves,
It is provided approximately in half of the range 1 on the entry/exit side 2 in a direction perpendicular to the vehicle entry direction. These water collection grooves 3, 4, and 5 are connected at one end to a side groove 6 for drainage. 7 and 8 are separate water supply pipes inserted into the side gutter 6, the base end of which communicates with the water supply source 9, and the other end of the water supply pipe 7 with the water supply pipes 10 and 12 inserted into the water supply grooves 3 and 5. The other end of the water supply pipe 8 is connected to the water supply pipe 1 in the water supply groove 4.
It is connected to 1. And these water supply pipes 10,
11 and 12 are provided with nozzles 13, 14 and 15, respectively.

Reference numeral 16 is a push button switch through which a worker inputs a signal indicating whether the vehicle is large or small, and is installed near the entrance of road surface area 1. Sensors 17, 18, and 19 are installed in relation to the road surface area 1 and are spaced apart from each other in the longitudinal direction of the road surface area 1, that is, in the direction of movement of the vehicle. These installation locations may be on the side of range 1 or above. These sensors are also connected to the push button switch 16 and the water supply source 9 via a cable 20, and which one is activated is determined by a large or small signal instructed by the switch 16.

In the drawing, 21 is a lid, 22 is a pipe holder, 23 is a mounting bracket, 24 is a main drain pipe, 25 is a water tank, 26
is the curb.

Now, when a large signal is input to the push button switch 16, the sensors 17 and 19 at both ends are activated. When a vehicle enters the area 1 from the entrance/exit side 2, the sensor 17 first detects the vehicle and the water supply source 9
A signal is sent to the water supply pipes 7, 10, and 12, and cleaning water is ejected from the nozzles 13 and 15. As the vehicle advances further, the lower part is washed sequentially, and when the tip is detected by the sensor 19, water supply stops.
By setting the number of detections by the sensor 19, the water supply can be stopped at an appropriate number of times as the vehicle repeatedly moves forward and backward, allowing for sufficient cleaning. Furthermore, since the vehicle is cleaned by the nozzles 13 and 15, the distance traveled within range 1 can be reduced to half the length of the vehicle.

In the case of a small size, the sensor 18 is activated by the push button 16. When a vehicle enters the range 1, this is sensed, and the water supply source 9 is activated to supply water to the water supply pipes 8 and 11, and the water is jetted from the nozzle 14. When the vehicle moves and the end comes, the sensor 18 detects this,
The water supply source 9 is stopped to complete the cleaning.

When water collection grooves 3, 4 and 5 are provided at approximately equal intervals,
In the case of a large vehicle, the entire length can be cleaned by moving half the length of the vehicle, making it more efficient. Furthermore, in the case of a small car, water is not supplied to the water supply pipes 10 and 12 at both ends, so loss of wash water can be prevented.

Sensors 17, 18 and 19 are provided on the approach side 1.
7 for the start of a large car wash, intermediate 18 for the start and end of a small wash, and inner end 19 for the end of a large car wash.
Just by moving inside the vehicle, the cleaning work can be done automatically according to each vehicle.

(Effects of the invention) According to the invention, the lower part of large and small vehicles can be automatically washed within a limited range by simply inputting a signal indicating whether the vehicle is large or small using a push button switch. This makes it easier to work in the cold, you can freely decide the number of times you want to wash, you don't have to use a hand gun, etc., and you can spray high-pressure water so you can wash in a short time.
If it is large, it can be cleaned with a stroke of half the length of the vehicle.The structure is extremely simple and there are no moving parts, so there will be no breakdowns, and it can be used stably for a long time.The surface within the area is flat and has no grooves or protrusions. There are no discontinuous parts on the plane, so it can be used as a plaza when not in use, and can be installed with at least a large vehicle length, and can be installed anywhere with a power source, water source, and drainage. There are various effects such as:
