Tubular culvert dredging device for water conservancy project

Abstract

The tubular culvert dredging device for the water conservancy project comprises an annular shell and is characterized in that the inner side of the annular shell is fixedly connected with a star-shaped support, the middle of the star-shaped support is movably connected with one end of a water pipe, and one end of the water pipe is fixedly communicated with one end of a rotating connector; one side of the other end of the rotary joint is fixedly connected with an L-shaped connecting rod, the other end of the L-shaped connecting rod is fixedly connected with the star-shaped support, the other end of the water pipe is fixedly communicated with the middle of an arc-shaped pipe, the arc-shaped pipe is fixedly communicated with a group of high-pressure sprayers which are uniformly distributed, and an inner gear ring is movably connected in the annular shell; and the annular shell is meshed with a power gear. The invention relates to the field of culvert dredging equipment, in particular to a tubular culvert dredging device for hydraulic engineering. The invention relates to a tubular culvert dredging device for hydraulic engineering, which is beneficial to dredging culverts with different diameters.

Description

technical field [0001] The invention relates to the field of culvert dredging equipment, in particular to a tubular culvert dredging device for water conservancy projects. Background technique [0002] Culvert refers to the water channel built under the road surface in order to make the road or railway pass through the canal smoothly in the construction of road or railway engineering. Through this structure, water can flow through the bottom of the road or railway, and it is used to cross natural valleys. The swales drain floodwaters or serve as canals for irrigation of farmland. The main function of culverts is to quickly remove surface water along roads or railways to ensure the safety of roadbeds. The function of the culvert is basically the same as that of the bridge, but the aperture is smaller, generally ranging from 0.75 to 6 meters. [0003] After the water flows through the culvert and after it has been idle for a long time, a large amount of silt will accumulate ...

AI Technical Summary

Problems solved by technology

[0003] After the water flows through the culvert and after it has been idle for a long time, a large amount of silt will accumulate in the culvert. If the accumulated silt is not cleaned up in time, it will cause more and more silt in the culvert, and finally lead to poor water flow in the culvert , or even completely blocked to lose function

[0004] At present, after the culvert is silted and blocked, due to the lack of effective dredging methods, it is generally not cleaned, and it is allowed to block

If manual cleaning and dredging is used, the culvert aperture is generally small, so people cannot enter

Even if the aperture of the culvert is large enough, because the length of the culvert is generally very long, it is not convenient for personnel to enter. This is the deficiency of the prior art
