Problems solved by technology

[0002] Most of the places with natural long-flowing water sources are located in low-valley areas such as open valleys and rivers. In the rainy season, there are many sudden flash floods, making it difficult for farmers to predict and control flash floods. Fish farming in long-flowing water sources, It will be impossible to control the fish from escaping due to rising water, so no one has invested heavily in long-flowing water sources and development
The conventional fish blocking used in the past is fixed, and the slag flowing down the water will adhere to the fish blocking net. After a large amount of accumulation, it will form a blockage, which will cause the water level to rise, the water will overturn the dam, or the fish blocking net will be washed away. Key Risks Controlled
However, it is very dangerous to manually discharge slag for emergency rescue.

Abstract

The invention discloses a flood control and fish blocking mesh capable of discharging slag automatically. The flood control and fish blocking mesh comprises an overflow weir, the top of the overflow weir is provided with three or more supporting piers, two of the supporting piers are located at the two ends of the overflow weir respectively, a waterwheel is arranged between the two adjacent supporting piers, a bearing of a rotating shaft of the waterwheel is fixed to the corresponding supporting piers, a fish blocking and slag discharging roller is arranged between the two adjacent supporting piers at the position adjacent to the waterwheel, the fish blocking and slag discharging roller is of a cylindrical structure, the outer surface of the fish blocking and slag discharging roller is of a grid structure, and a bearing of a middle shaft of the fish blocking and slag discharging roller is fixed to the corresponding supporting piers. According to the flood control and fish blocking mesh, the fish blocking and slag discharging roller is utilized to replace an existing fish blocking mesh, the waterwheel drives the fish blocking and slag discharging roller to rotate continuously, so that wave slag attached to the roller is removed, meanwhile fish is prevented from escaping, the operation power of the mesh is the water flowing power, extra external power is not needed, the structure is simplified, and reliability is improved.

Description

technical field [0001] The invention relates to the technical field of water conservancy, in particular to an automatic slag-discharging and flood-controlling fish-stopping net. Background technique [0002] Most of the places with natural long-flowing water sources are located in low-valley areas such as open valleys and rivers. In the rainy season, there are many sudden flash floods, making it difficult for farmers to predict and control flash floods. Fish farming in long-flowing water sources, It will be impossible to control the fish from escaping due to rising water, so no one has been investing and developing vigorously in long-flowing water sources. The conventional fish blocking used in the past is fixed, and the slag flowing down the water will adhere to the fish blocking net. After a large amount of accumulation, it will form a blockage, which will cause the water level to rise, the water will overturn the dam, or the fish blocking net will be washed away. Key ris...
