Integrated silt loosening and sucking device for removing silt

Abstract

The invention discloses an integrated silt loosening and sucking device for removing silt, which comprises a high-pressure water inlet pipe, a high-pressure water nozzle, a silt suction head cap and asilt outflow pipeline, wherein the silt suction head cap is connected with one end of the silt outflow pipeline; the high-pressure water inlet pipe comprises a first water outlet and a second water outlet; a high-pressure water flow passage is arranged in the silt outflow pipeline; the inlet of the high-pressure water flow passage is connected with the second water outlet; the outlet of the high-pressure water flow passage is communicated with the inner cavity of the silt outflow pipeline and is in the same direction of the silt outflow pipeline; the high-pressure water nozzle is arranged onthe silt suction head cap; and the water inlet of the high-pressure water nozzle is connected with the first water outlet of the high-pressure water inlet pipe. Compared with the prior art, the devicehas the advantages of reasonable and simple integral structure, light weight, convenient transportation and no movable components, has the functions of modularized unit combination and the like and is free of maintenance; the specification and the performance of the device conform to the dredging standard; the device is peculiar in structural design, and can regulate the optimal flow rates for suction and spraying according to the characteristics of the silt; the device can drain flow smoothly; and the pipe cavity is not easily blocked.

Description

technical field [0001] The invention relates to the technical field of river dredging, in particular to a dredging device used for river dredging silt. Background technique [0002] There are many rivers and lakes in my country's water network area, and the water system is developed, but the problem of river sedimentation is becoming more and more prominent. Excessive sedimentation in the river channel will make the effective depth of the river channel shallow, the water body capacity and drainage and irrigation capacity will decrease, the source pollution of the water body will increase, the water ecological environment will deteriorate, the comprehensive agricultural production capacity will be weakened, and the production and life of the people will be affected. Dredging is the most effective engineering measure for rural water resources, water ecology and water environment protection. [0003] There are three types of dredging technology structures for small river chann...

Problems solved by technology

[0003] There are three existing technical structures for dredging small rivers both at home and abroad. One is to drain the water in the river with a water pump after damming, and then use a mud pump to pump the mud to the bank for sedimentation. The mud is not easy to extract; the second is to use the grab excavator to work on the river embankment to dig out the silt in the river channel, stack it on the spot or transport it away by vehicle and boat, but it is not easy to work due to the width of the river channel and embankment; the third is to use water The lower dredging machine is characterized in that the whole machine pumps the mud to the bank for sedimentation while walking in the water. It can work with water, but it is not easy to control, the price of the machine is high, and it is difficult to carry after the operation is completed.
