Abstract

The invention discloses an oncomelania blocking wall and an oncomelania settling pond for water conservancy and hydropower engineering. The oncomelania blocking wall comprises an oncomelania blockingmechanism; the lower part of the oncomelania blocking mechanism is provided with a flow guiding mechanism, and the oncomelania blocking mechanism comprises a plurality of oncomelania blocking plates;the oncomelania blocking plates are arranged side by side and hinged together to form an oncomelania blocking portion, and a floating body is arranged on the upper portions of the oncomelania blockingplates; two sides of the oncomelania blocking portion sleeve main shafts correspondingly, and the oncomelania blocking portion can freely slide in the axial direction of the main shafts; and the flowguiding mechanism is located below the oncomelania blocking portion, the flow guiding mechanism is formed by connecting a plurality of flow guide plates in series, and the two sides of the flow guiding mechanism are fixedly connected with the lower portions of the main shafts correspondingly. According to the oncomelania blocking wall and the oncomelania settling pond, the water flow can be quickly recovered stably while the interception effect is guaranteed so as to make the oncomelania settle rapidly, so that the effects of interception and settling of the oncomelania are remarkably improved, and the defects existing in the prior art are overcome.

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...
