Dredging robot blowdown system

Abstract

A dredging robot blowdown system comprises a dredging equipment shell, a motor, an internal blowdown pipe, an impeller pump, a sewage suction pipe, a hydraulic motor, a bucket, an auger, a butt joint valve and an external blowdown pipe. The motor provides power for the impeller pump, the upper portion of the impeller pump is connected with the internal blowdown pipe, the right side of the impeller pump is connected with one end of the sewage suction pipe, the other end of the sewage suction pipe is connected with the bucket, the auger is arranged in the bucket, the hydraulic motor is arranged on the side wall of the bucket, the hydraulic motor drives the auger to rotate in the bucket, and an inlet channel is formed in the internal blowdown pipe. The butt joint valve is arranged on the outer side of the dredging equipment shell and communicates with the internal blowdown pipe and the external blow-off pipe.

Description

technical field [0001] The invention relates to the field of urban pipeline dredging, in particular to a dredging robot sewage system. Background technique [0002] The current application fields of dredging equipment are mainly distributed in dredging environments such as dam dredging, circulating pool dredging, urban culvert dredging, large pipeline dredging, urban river dredging, culverts, etc. The main difficulty of such dredging work is The working environment is complex, and divers cannot go deep into dangerous areas such as the bottom of the culvert. Manual survey and manual dredging will greatly reduce work efficiency. As for the dredging equipment in the urban pipeline network, due to the lack of maintenance of the municipal pipeline network all year round, it is easy to produce silt with a thickness of 0.1 m-0.7 m, and many old pipelines in the urban area adopt the method of confluence of rain and sewage. When it is too late, it is easy to cause blockage and cause...

AI Technical Summary

Problems solved by technology

[0004] 1. The dredging equipment in the prior art transports the adsorbed sludge to the downstream treatment process through pipelines. However, the sludge pipeline needs to be controlled on and off, which requires valves to be installed on the sludge pipeline. However, for flexible pipes, The valve cannot be supported at all; the solution to this problem in the prior art is to set the valve inside the equipment casing, which makes the inside of the equipment casing more crowded, and when there is a need for replacement, maintenance, etc., it is inconvenient to disassemble and repair the valve

[0005] 2. In the dredging pipeline of the prior art, after the work is completed, there are dead angles in important parts such as valves, and the silt in the dead angle will accumulate and harden, blocking the pipeline

[0006] 3. The dredging technology under the existing technology includes technologies such as purging and cleaning. However, both purging and cleaning require additional media, such as the storage of cleaning fluid, which will take up a lot of space

[0007] 4. The dredging technology under the existing technology can only complete a single dredging, and the cost of circular dredging is relatively high and takes up a lot of space, such as the dredging assembly line

[0008] 5. The dredging pipelines in the prior art are often bent at right angles, and an inclined guide surface can be optionally provided, but standard molds cannot be used for the guide surface, which will increase the cost of processing molds

[0009] 6. For non-assembly lines, it is difficult for a single small-volume valve to collect after dredging, or there is nowhere to place the dredged sludge
