A waste retention dam for water conservancy river pollution control

Abstract

The invention relates to a garbage interception dam for hydraulic river pollution control. The garbage interception dam comprises a dam body, adjusting mechanisms and an interception mechanism. The adjusting mechanisms are arranged in the middle of the dam body. The interception mechanism is mounted on the rear side face of the adjusting mechanisms. The total number of the adjusting mechanisms istwo. The two adjusting mechanisms are arranged in the middle of the dam body in bilateral symmetry. Each adjusting mechanism comprises an adjusting electric push rod. Adjusting grooves are formed in the middle of the dam body. According to the garbage interception dam, the problems that during manual fishing of river pollution, cost is high, the fishing quantity is low, when garbage is interceptedby the interaction dam, an interception net cannot adjust the height along with water level changes, the interception net is prone to being blocked, water drainage is difficult, even cracking is generated, when the interception net s cleaned, garbage at an interception opening is prone to directly flowing towards the downstream portion, and the interception net is difficult to clean can be solved; the function of intercepting garbage in a river can be achieved; and the garbage interception dam has the advantages that the interception quantity is large, the input cost is low, blocking is not prone to happening, the interception net is convenient to clean, and garbage at the interception opening cannot flow away during cleaning.

Description

technical field [0001] The invention relates to the field of environmental treatment of water conservancy rivers, in particular to a garbage retaining dam for water conservancy river pollution control. Background technique [0002] The development of the economy is also accompanied by the pollution of the environment by human beings. Plastic bags are known as the most successful and also the most failed invention. It is convenient for people's daily life, but it is also polluting the earth on which human beings live. This year, rivers and lakes can be seen everywhere in people's daily life such as garbage bags, old clothes, etc. The pollution of rivers has only increased, forcing the country to remediate river pollution. River pollution remediation is the most important task of water conservancy projects. one. [0003] In the existing methods of river improvement, there is manual cleaning and salvage of the rubbish in the river, but the input cost is high and the amount of ...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above problems, the present invention provides a garbage retention dam for water conservancy river pollution control, which can solve the problem of high investment cost and low salvage amount when manually salvaging river pollution, and the interception net cannot adjust the height with the change of water level when the retention dam intercepts garbage. The interception net is easy to block, difficult to drain, and even ruptures. When cleaning the interception net, the garbage at the interception port is easy to flow directly to the downstream and the retention net is difficult to clean. The advantages of low cost, not easy to be blocked, easy to clean the interception net, and the garbage at the interception port will not flow away during cleaning
