[0026] When the water cart needs to be adjusted to a wider lane while driving, the telescopic water spraying system can be started through the controller in the cab. The steering motor 9 receives the extension steering angle signal, and the steering motor 9 controls the deflection of the drive wheel 11. The drive wheel shaft drives the drive wheel 11 to rotate, and the drive wheel 11 moves forward at an angle of 45 degrees to the vertical plane in which the drive wheel 11 and the driving direction of the water cart are located. The drive wheel 11 drives the telescopic mechanism to extend, ensuring that the water cleaning system can be stretched and widened while the vehicle is driving. Through the stretching process, the overall movement is driven. The movement trajectory is formed by the linkage effect of the upper shaft 6 driven by the middle connecting rod 5 connected by the lower shaft 6 driven by the head main support rod 7 fixed on the steering motor 9. The tail limiting rod 3 controls the stretching distance, and the minimum folding angle is 45 degrees when stretched to the limit. Thus, the stretching length of the telescopic mechanism is controlled to avoid overstretching. At the same time, the extension effect of responding to road changes can be maximized, and the spraying function can be started in the cab. The water supply system starts water supply through the water supply pipe 19 in the support cavity 1, and the soft water pipe connected by the middle positioning pin 8 of the spray head delivers water to the spray head 4, starting the water cleaning program. The water inlet end of the soft water pipe is connected to the water supply pipe 19, and the water outlet end of the soft water pipe is connected to the spray head 4. A middle positioning pin is arranged on each middle connecting rod 5, and the soft water pipe is arranged on the middle positioning pin.

[0027] When the water cart needs to be adjusted to a narrower lane while driving, the telescopic water spraying system can be started through the controller in the cab. The steering motor 9 receives the contraction steering angle signal, and the drive wheel shaft drives the drive wheel 11 to contract and move backward at an angle of 45 degrees to the vertical plane in which the drive wheel 11 and the driving direction of the water cart are located. This ensures that the water cleaning system can be contracted while the vehicle is driving. Through the contraction process, the overall movement is driven, and the contraction mechanism is switched from the extended state to the contracted state. The movement trajectory is formed by the linkage effect of the upper shaft 6 driven by the middle connecting rod 5 connected by the lower shaft 6 driven by the head main support rod 7 fixed on the steering motor 9. The tail limiting rod 3 controls the contraction distance, and the maximum expansion angle is 180 degrees when contracted. Thus, the contraction distance is controlled to avoid over-contracting. At the same time, the contraction response effect of responding to road changes can be maximized, and the spraying function can be started in the cab. The water supply system starts water supply through the water supply pipe 19 in the support cavity 1, and the soft water pipe connected by the middle positioning pin 8 of the spray head delivers water to the spray head 4, starting the water cleaning program.

[0028] If the retraction function fails to retract or the lane narrows, the auxiliary retraction function is started. The auxiliary retraction line 14 and the second auxiliary extension line 17 are pulled together by the auxiliary retraction motor 2, and the spraying system is retracted from the head retraction positioning pin 13 through the limiting wheel 15. When the lane narrows, the motor controls the retraction stroke.

[0029] Meanwhile, the front limiting transverse rod 16 ensures the stability and structural deformation resistance of the whole system during retraction or forward movement.

[0030] When the spraying task is completed, the closing program is started. The steering motor 9 receives the retraction steering angle signal, drives the driving wheel 11 to the rear at an angle of 45 degrees, and retracts the rear row until it is completely retracted into the telescopic storage 18. At the same time, the steering motor 9 starts the folding mode, retracts the connecting rod between the driving axle 10 and the steering motor 9, achieves the effect of retraction and separation from the ground, and the remaining two support wheels in the same horizontal position are folded in the same way. Ensure that it does not affect the normal driving of the whole vehicle.

[0031] The above describes the present application in conjunction with the drawings, and it is obvious that the specific implementation of the present application is not limited by the above method. Any non-essential improvement or direct application of the concept and technical solution of the present application to other occasions without improvement is within the protection scope of the present application.
