Energy-saving feeding device for fish farming in ecological flowing water

Abstract

The invention belongs to the technical field of aquaculture, especially an energy-saving feeding device for ecological running water fish farming. Aiming at the problem that the existing running water fish feeding device needs to use a large number of motors for spraying and consumes a large amount of power, it is now proposed The following solution includes a support floating plate, a first through hole is provided on the central outer wall of the top of the support floating plate, and a vertical support rod is slidably connected to the inner wall of the first through hole, and the top outer wall of the support floating plate is connected by bolts A vertical storage box. In the present invention, the energy-saving feeding device for ecological flowing water fish farming is provided with a convex support block. When the water flows through the convex support block, a flow velocity difference will be formed at the bottom of the convex support block, which will further give the convex support Block an upward pressure, thereby improving the buoyancy of the supporting floating plate on the water surface, which can effectively avoid the pressure of the feed on the supporting floating plate and cause the floating plate to sink, thereby affecting the effect of discharging.

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...
