Automatic dredging device for water suction end of large-flow remote water conveying pipe for emergency rescue

Abstract

The invention provides an automatic desilting device for the water suction end of a large-flow remote water conveying pipe for emergency rescue, and belongs to the technical field of long-distance water conveying for emergency rescue, the automatic desilting device comprises a floating box, a collecting box, a filter plate, a water suction pipe and a pollution discharge assembly; the filter plate is horizontally arranged, and a plurality of filter holes are formed in the filter plate; the buoyancy tank is fixed on the bottom surface of the filter plate, and a water inlet port of the water suction pipe is arranged on the bottom surface of the filter plate; the collecting box is fixed on the top surface of the filter plate, and a feeding hole is formed in the side surface of the collecting box; and the pollution discharge assembly is arranged above the filter plate and is configured to be capable of sweeping impurities on the top surface of the filter plate into the collection box. The filter plate is arranged on the water surface through the floating box, the water suction pipe sucks water from top to bottom, impurities in water are blocked by the filter plate before entering the water suction pipe and can be cleaned into the collecting box by the pollution discharge assembly, and safe operation of the large-flow long-distance water conveying system is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of long-distance water delivery for emergency rescue, in particular to an automatic dredging device for the suction end of a large-flow remote water delivery pipe for emergency rescue. Background technique [0002] When carrying out rescue work such as firefighting, drought resistance, and drainage, large-flow and long-distance water delivery is required. When self-priming water conveying equipment carries out large-flow and long-distance water conveyance operations, it is necessary to lay flexible suction pipes into the water source. Equipment was shut down, causing rescue efforts to fail. SUMMARY OF THE INVENTION [0003] In view of this, the present invention aims to provide an automatic dredging device for the suction end of a large-flow remote water pipe for emergency rescue, so as to alleviate the above-mentioned technical problems. [0004] In order to achieve the above object, the technical schem...

AI Technical Summary

Problems solved by technology

[0002] When carrying out rescue work such as firefighting, drought resistance, and flood drainage, large-flow long-distance water delivery is required. The water source is generally a natural water source such as a river or a lake, and the natural water source is generally rich in impurities, such as aquatic plants, branches, silt, etc. Use When the self-priming water delivery equipment is used for long-distance water delivery with a large flow rate, it is necessary to lay a flexible suction pipe into the water source. If the method is used to directly enter the water, even if filtering measures such as filters are adopted, the suction pipe will easily be blocked, resulting in Equipment downtime, resulting in failure of rescue work
