[0015] Compared with the prior art, the high-pressure spraying device for cleaning municipal public facilities has the following beneficial effects: 1. The high-pressure spraying device for cleaning municipal public facilities, by starting the motor, drives the rotating rod to rotate, the rotating rod drives the cam to rotate, when the protruding part of the cam abuts against the sliding rod, the sliding rod slides on the inclined surface of the trapezoidal plate, at this time, under the guidance of the vertical rod and the first L-shaped plate, the trapezoidal plate and the vertical rod drive the rubber hammer to slide upward to knock the bottom of the filter plate once, so that the filter plate moves upward while generating vibration, the vibration can effectively prevent the particles from forming a close accumulation, the vibration can make the particles deposited on the filter plate be in an unstable state, the binding force between the particles is destroyed, thereby preventing the filter plate from being blocked in the process of continuously filtering underground water, and greatly improving the cleaning efficiency of municipal public facilities.

[0016] 2. The high-pressure spraying device for cleaning municipal public facilities operates by rotating a horizontal plate upwards. The plate rotates on an L-shaped support rod, and the other end of the plate rotates under the action of a hinge, pulling a third L-shaped plate downwards. This third L-shaped plate slides downwards within the circular groove of a telescopic rod by compressing a fourth spring. This causes the lower end of the telescopic rod to move downwards, pushing two push rods to rotate. The two push rods then push two friction blocks to slide within a rectangular frame, moving them away from each other until their sides contact the inner wall of the rotating drum. This causes the two friction blocks to rotate with the rotating drum, resulting in simultaneous rotation of the rectangular frame, push rods, and telescopic rod. The third L-shaped plate does not rotate. When the horizontal plate is released, the fourth spring automatically resets the third L-shaped plate upwards, causing the telescopic rod to retract upwards. This pulls the two push rods to rotate, causing them to move closer together, gradually disengaging the two friction blocks from the inner wall of the rotating drum. Finally, the telescopic rod stops rotating. This system achieves automatic control and is simple, convenient, and quick to operate.

[0017] 3. The high-pressure spraying device for cleaning municipal public facilities uses a horizontal plate that rotates upwards to power the telescopic rod's rotating drum. This continuous rotation of the telescopic rod drives the top protrusion to rotate continuously. The piston cylinder reciprocates, drawing detergent from the detergent tank through the suction pipe, then reciprocatingly entering the spray pipe through the inlet pipe, and finally spraying it out from the high-pressure spray gun. This automatic detergent extraction effectively cleans oil stains and other dirt from garbage stations. The device also automatically controls whether detergent is needed. When detergent is no longer required, the operator simply releases the horizontal plate, and the fourth spring automatically stops the detergent application. This automatic control makes the device more convenient to use, resulting in better cleaning of municipal public facilities, cleaner surfaces, and significantly improved work efficiency.
