Description

Technical Field

[0001] This utility model relates to the field of cleaning device technology, specifically a high-pressure cleaning device for highway maintenance. Background Technology

[0002] Road cleaning is a systematic operation that uses high-pressure water guns, cleaning trucks, and other equipment to remove deposits from highways, plaza surfaces, and sewer pipes. This operation combines mechanized cleaning with manual labor, and includes a three-step process of sweeping, washing, and rinsing. It effectively removes pollutants such as oil, mud, and fallen leaves. Regular cleaning operations can reduce dust pollution, extend the service life of roads, and reduce traffic accidents caused by slippery road surfaces.

[0003] As disclosed in the patent announcement CN215052553U, a road maintenance technology field, particularly a high-pressure cleaning device for highway maintenance, includes a base plate, a mounting plate on the top of the base plate, an angle adjustment mechanism for driving the mounting plate to rotate fixedly installed on the bottom of the base plate, a water tank with an arc shape installed on the top of the mounting plate, a filter structure on the top of the water tank, a cleaning assembly installed on the top of the mounting plate, and rollers for movement rotatably installed on the bottom of the base plate.

[0004] Although it enables the motor to be turned on, the motor provides power to the drive gear disk, driving the drive gear disk to rotate. The drive gear disk meshes with the driven gear disk to form a gear transmission structure, thereby driving the driven gear disk and the rotating rod to rotate, causing the mounting plate and the nozzle to rotate together. This allows the cleaning angle to be changed without the need for manual rotation, increasing cleaning efficiency.

[0005] However, the existing cleaning devices of this type are not conducive to convenient high-pressure cleaning of highways, are not convenient to adjust the cleaning range, are not convenient for multi-stage cleaning of highways, and are not convenient to tilt the cleaning position of the high-pressure cleaning device, which affects the efficiency of highway cleaning and causes great trouble for users.

The drive rod drives the rocker arm to rotate via the power shaft, which in turn drives the rotating shaft to rotate. The rotating shaft then drives the hollow ball sleeve to rotate, allowing for convenient multi-position adjustment of the cleaning position. This enables the high-pressure cleaning device to perform convenient multi-stage cleaning of the road, facilitates multi-angle adjustment of the cleaning position, and increases the cleaning range of the high-pressure cleaning device.

[0021] The third electric push rod drives the drive frame to rotate around the second shaft via the first shaft. The drive frame drives the transmission frame, main water pipe, auxiliary water pipe, and high-pressure nozzle to rotate easily. The power motor drives the worm gear to rotate, the worm gear drives the worm wheel to rotate, the worm wheel drives the third shaft to rotate, and the third shaft drives the transmission frame to rotate. The support shaft provides movable support for the transmission frame, facilitating the rotation of the main water pipe, auxiliary water pipe, and high-pressure nozzle. This also facilitates the tilt adjustment of the high-pressure cleaning device's cleaning position, allowing for multi-angle cleaning of the highway and improving the efficiency of highway cleaning.
