An automatic fishing device installed downstream of the gate

Abstract

The present invention is an automatic fishing device installed downstream of a gate, which includes a mobile fixing frame and a device body. The device body includes a catch channel and a buffer box. There is an inlet channel, and a rotating screen is set in the capturing channel, and the rotating screen rotates from the outside to the direction of the inlet channel, and the inlet channel extends upward along the inner wall of the capturing channel to the lower side of the rotating screen, and the bottom of the buffer box is connected with an energy dissipation plate ; It can catch the fish in the process of flood discharge, overcome the phenomenon that a large number of fish escape with the flood when the reservoir discharges the flood, and has many excellent characteristics such as economy, environmental protection and high efficiency.

Description

technical field [0001] The invention belongs to the technical field of water conservancy facilities, and in particular relates to an automatic fishing device installed downstream of a gate. Background technique [0002] In the past, the spillway was generally built on one side of the dam, mainly to prevent the dam from being destroyed, including the control gate and the maintenance gate. The control gate is generally installed at the end of the spillway, which is an important part of the dam's flood control and flood control. It has been full of various risk factors since ancient times, but with the advancement of people's breeding technology in modern technology, the principle of flood discharge has been more applied to the construction of water conservancy daily life. Fishing devices are built in many common water conservancy projects. Fishing devices need With the principle of the flood gate, the fish in the upper reaches of the reservoir can be rushed to the gate through...

[0002] In the past, the spillway was generally built on one side of the dam, mainly to prevent the dam from being destroyed, including the control gate and the maintenance gate. The control gate is generally installed at the end of the spillway, which is an important part of the dam's flood control and flood control. It has been full of various risk factors since ancient times, but with the advancement of people's breeding technology in modern technology, the principle of flood discharge has been more applied to the construction of water conservancy daily life. Fishing devices are built in many common water conservancy projects. Fishing devices need With the principle of the flood gate, the fish in the upper reaches of the reservoir can be rushed to the gate through the gate, and enter the fishing device with the water flow. However, due to the high cost of this fishing device and low operability, it is easy to cause a large number of fish Escape, affecting the efficiency of fish farming
