Fish passing device for water conservancy and hydropower dam

Abstract

The invention discloses a fish passing device for a water conservancy and hydropower dam. The fish passing device comprises the dam, a working box, a lifting pipe and a fish collecting box; a supporting frame is arranged at the top of the dam, and the working box is arranged at the top of the supporting frame; a solar cell panel is arranged at the top of the working box, and an electric storage box is arranged at the inner bottom of the working box and electrically connected with the solar cell panel; one side of the electric storage box is provided with a motor, and a rope winding ring is arranged on an output shaft of the motor; a timing control switch is arranged on the inner side of the working box and electrically connected with the motor; the bottom of the working box is connected with the lifting pipe, and an inclined slideway is formed in one side of the lifting pipe and penetrates through the supporting frame; and a case is arranged on the other side of the lifting pipe, and aspray head is arranged on one side of the case. The fish passing device can be automatically charged through the solar cell panel to be used, and is capable of saving energy and protecting the environment, convenient to use, high in fish passing efficiency and suitable for being used and popularized.

Description

technical field [0001] The invention relates to a fish passing device, in particular to a fish passing device for a water conservancy and hydropower dam. Background technique [0002] A dam is a water-retaining structure used to intercept the water flow of a river to raise the water level or adjust the flow. When the dam intercepts the water flow, it will also prevent fish from passing through, so that some fish cannot return to the spawning ground to lay eggs. Thereby affecting the reproduction and survival of some fishes, the existing fish passing devices often cannot effectively attract fish and send them to the other side of the dam, and the fish passing efficiency is low. For this reason, we propose a kind of fish passing device of water conservancy and hydropower dam. Contents of the invention [0003] The main purpose of the present invention is to provide a fish passing device for water conservancy and hydropower dams, which can effectively solve the problems in t...
