Desilting device capable of self-adapting to sizes of kidney-shaped holes in sewer cover plate

Abstract

The invention relates to a desilting device capable of self-adapting to sizes of a kidney-shaped holes in a sewer cover plate. The desilting device is characterized in that a vertical pull handle, a supporting arm, an impact hammer and dirt flushing rods serve as a main body; a transverse pressing handle is arranged at the lower end of the vertical pull handle; the supporting arm is arranged at the position, located at the lower end of the transverse pressing handle, of the vertical pull handle, and square supporting rods fixedly connected with the supporting arm are arranged at the two ends of the supporting arm; a sliding plate capable of sliding up and down is arranged on each square supporting rod, and an impact pad and a magnetic plate which are fixedly connected with the sliding plate are arranged on the upper face and the lower face of each sliding plate correspondingly; a kidney-shaped fixing plate fixedly connected with the square supporting rod is arranged at the bottom of each square supporting rod; and a central positioning column and a telescopic column which is matched with the central positioning column and can slide up and down are arranged in the middle of the supporting arm. The dirt flushing rods arranged in the kidney shape can be impacted and inserted into the kidney-shaped holes of the different sizes of the sewer cover plate, and the design is ingenious;and the vertical pull handle and the transverse pressing handle are convenient for applying force and mastering squares, the operation is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of road cleaning auxiliary devices, in particular to a dredging device that can adapt to the size of a waist-shaped hole on a sewer cover plate. Background technique [0002] Generally, there are drainage ditches underground on both sides of the road; along the drainage ditch, a centralized drainage outlet will be set at intervals, and the centralized drainage outlet will be connected with the drainage ditch, and a sewer cover plate or It is a trench cover. The main function of the sewer cover or the trench cover is to prevent the rainwater in the city and the road from flowing into the drain from the centralized drain, and weeds and branches also enter the drain and block the drainage. ditch. [0003] The drain cover can effectively prevent larger objects from entering the drain. The existing drain cover includes a cover body, and a downward waist-shaped hole is opened on the upper end of the cover body, b...

Problems solved by technology

[0003] The drain cover can effectively prevent larger objects from entering the drain. The existing drain cover includes a cover body, and a downward waist-shaped hole is opened on the upper end of the cover body, but the waist-shaped hole is The structure with the same upper and lower opening areas is easy to manufacture; when the weeds and branches on the cover plate and on both sides of the road are cleaned by the sweeper, dust will continue to accumulate on the waist-shaped hole of the cover plate, and after encountering rainwater, the dust will It will accumulate and block the waist-shaped hole on the cover plate, causing the drain outlet to fail to drain, and it is easy to cause corrosion of the cover plate and reduce the service life
