Energy-saving feeding device for ecological running water fish culture

Abstract

The invention belongs to the technical field of aquiculture, in particular to an energy-saving feeding device for ecological running water fish culture, and aiming at solving the problem that the existing running water fish culture feeding device needs to use a large amount of motors for spraying feed and consumes a large amount of electric power, the invention provides the following scheme that the device comprises a supporting floating plate, the outer wall of the center of the top of the supporting floating plate is provided with a first through hole, the inner wall of the first through hole is connected with a vertically arranged supporting rod in a sliding manner, and the outer wall of the top of the supporting floating plate is connected with a vertically arranged storage box body through a bolt. According to the energy-saving feeding device for ecological running water fish culture, a convex supporting block is arranged, a flow velocity difference is formed at the bottom of theconvex supporting block when water flows through the convex supporting block, then an upward pressure can be exerted on the convex support block, thereby the buoyancy of the supporting floating plateon the water surface is improved and the sinking of the floating plate due to the pressure of the feed on the supporting floating plate so as to influence the discharging effect is effectively prevented.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an energy-saving feeding device for ecological flowing water fish farming. Background technique [0002] Flowing water fish farming refers to the method of high-density intensive fish farming in fish ponds with water exchange. Generally, reservoirs, lakes, rivers, mountain streams, springs, etc. are used as water sources, and water continuously flows through fish ponds with the help of water level differences, drainage or closure facilities, and water pumps. Since the water flow plays the role of inputting dissolved oxygen and removing fish excrement, the pool water can maintain good water quality, creating conditions for high-density fish farming. Therefore, flowing water fish farming technology has become a new type of aquaculture method in recent years. During the breeding process, fish schools need to be fed, and the flowing water flow makes feeding difficult, so a feedi...
