Abstract

The invention discloses a snail blocking wall and a snail settlement tank for water conservancy and hydropower projects, comprising a snail blocking mechanism, the lower part of the snail blocking mechanism is provided with a flow guide mechanism, the snail blocking mechanism includes a plurality of snail blocking plates, and the snail blocking mechanism includes a plurality of snail blocking plates. The screw plates are arranged side by side and hinged together to form a screw blocking part. The upper part of the screw blocking plate is provided with a floating body. The two sides of the screw blocking part are respectively sleeved on the main shaft, and the screw blocking part can slide freely along the axial direction of the main shaft. The flow guide mechanism is located below the screw blocking part, and the flow guide mechanism is formed by a plurality of flow guide plates connected in series, and both sides of the flow guide mechanism are respectively fixedly connected with the lower part of the main shaft. The snail blocking wall and the settlement tank of the present invention, while ensuring the interception effect, can quickly restore the water flow to be stable, and then make the oncomelania sink and settle quickly, and the effect of oncomelania interception and settlement has been significantly improved, solving the problems in the prior art. There are deficiencies.

Description

technical field [0001] The invention relates to the technical field of oncomelania treatment in water areas, in particular to a snail-blocking wall for water conservancy and hydropower projects and a formed oncomelania settlement pond. Background technique [0002] Schistosomiasis is a water-borne, zoonotic major infectious disease that is prevalent in Asia, Africa, and South America, and is listed by the World Health Organization as a highly recurring infectious disease. Schistosomiasis has been prevalent in southern my country for more than 2,100 years. At present, it is still prevalent in 7 provinces of Jiangsu, Anhui, Jiangxi, Hunan, Hubei, Yunnan, and Sichuan in the Yangtze River Basin of China, seriously endangering the health and life safety of people in the affected areas, hindering local economic development and social progress. [0003] Oncomelania inhabits freshwater waters and is amphibious. In areas where oncomelania breeds, schistosomiasis is basically prevalen...
