Fish releasing device suitable for hydraulic and hydroelectric engineering

Abstract

The invention discloses a fish releasing device suitable for hydraulic and hydroelectric engineering. The fish releasing device suitable for hydraulic and hydroelectric engineering comprises a shell,a motor, a valve and a transmission device, wherein an anti-sliding structure is arranged on the bottom of the shell; an opening which communicates to the bottom of the shell is formed in the front surface of the shell; the valve is mounted in the opening in a liftable manner; the motor is in transmission connection with the valve through the transmission device to drive the valve to lift and fall; the transmission device comprises a gear and a rack; the rack is fixedly mounted on the outer side of the valve, and is fixedly mounted on an outputting shaft of the motor; and the rack cooperates with the gear. The fish releasing device suitable for hydraulic and hydroelectric engineering is simple in structure, can be placed on a riverbank, and is fixed conveniently and firmly; fishes can freely enter a river way; the device is simple; and the cost is low.

Description

technical field [0001] The invention belongs to the technical field of water conservancy equipment, in particular to a fish release device suitable for water conservancy and hydropower projects. Background technique [0002] At present, with the gradual enhancement of the country's awareness of the environment, the construction of water conservancy and hydropower projects has paid more and more attention to the protection of the environment, especially the protection of fish and river organisms is very important, and most of the water conservancy and hydropower projects have increased requirements for fish protection. Its value-added release, but due to the small size of some fry during the release process, they cannot withstand the impact of the water flow and high-altitude throwing. Nowadays, when people release fish, they all adopt more traditional methods. Just drop fry directly at high altitude, cause a lot of fry damage or die, do not satisfy people's needs. Contents...

Its value-added release, but due to the small size of some fry during the release process, they cannot withstand the impact of the water flow and high-altitude throwing. Nowadays, people use more traditional methods when releasing fish. It is to throw the fry directly at high altitude, causing a lot of damage or death of the fry, which does not meet people's needs
