By designing the fixing structure, not only the stable and reliable fixing of the engine 42 and the vehicle body 11 is realized, but also the vibration generated by the operation of the engine 42 is absorbed by the shock-absorbing rubber pier, so that the vibration transmitted to the vehicle body 11 is reduced, and the vibration noise is reduced.

In order to control the cleaning vehicle to move conveniently, the control system also comprises a key door, a starter, a rocker switch, an accelerator handle, a brake handle, a speed regulator and the like. The key is inserted into the key door, and when the key is screwed to the starting position, the starter is started; the rocker switch is connected with the controller, sends a forward gear signal and a backward gear signal to the controller, and controls the rotation direction of the walking motor through the controller so as to control the forward and backward of the vehicle body; the accelerator handle is connected with the controller, sends an acceleration command to the controller, and controls the rotation speed of the walking motor to increase through the controller; the brake handle is connected with the controller, sends a brake command to the controller, and controls the brake to run through the controller so as to brake the travelling wheels; the regulator 11 is connected with the controller and used for adjusting the maximum rotating speed of the walking motor and realizing the speed control of the vehicle body 11.

When the cleaning vehicle is used, the controller controls the engine 42 to run, and the throttle handle controls the vehicle body 11 to move. The engine 42 drives the booster pump 43 to operate, and provides high-pressure water flow, and the high-pressure water flow is transmitted to the spray head 34 or the spare spray head 71, and the spray head 34 or the spare spray head 71 converts the high-pressure water flow into high-pressure water mist, so that cleaning and dust removal are realized.

The above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions.
