Fishpond oxygenation device

Abstract

The invention belongs to the technical field of aquaculture, particularly relates to a fishpond oxygenation device, and aims to solve the problems that a fishpond is directionally inflated through anair pump, the oxygen supply manner is only suitable for a small range, and the oxygenation efficiency is low. According to the scheme, the fishpond oxygenation device comprises a floating plate, and amounting pipe is fixedly connected to the center of the outer wall of the top of the floating plate; and a piston rod is inserted into the inner wall of the mounting pipe, a piston plate is fixedly connected to the outer wall of the piston rod, the outer wall of the piston plate is matched with the inner wall of the mounting pipe, an air bin is arranged in a space above the piston plate, a hose is fixedly connected to one side of the outer wall of the bottom of the piston plate, and the top end of the hose communicates with the air bin above the piston plate. According to the fishpond oxygenation device, fish schools are guided to collide with a water stirring plate at high frequency to extrude the air bin above the piston plate, air in the air bin enters the fishpond from a spray head through the hose and the connecting pipe in the extrusion process, and fishpond oxygenation is completed autonomously in a fish school guiding manner.

Description

technical field [0001] The invention relates to the technical field of aquaculture, in particular to an aeration device for fish ponds.

Problems solved by technology

[0003] The existing fish pond oxygenation device has the following problems: During the fish pond cultivation process, it is necessary to pay special attention to the quality change of the water body. On the issue of oxygen supply to the water body, the existing device often uses an air pump to inflate the fish sugar in a directional manner. This method of oxygen supply is only applicable to a small range, and the efficiency of oxygenation is low, and the existing technology is not easy to solve such problems. Therefore, there is an urgent need for fish pond oxygenation devices to solve the above problems
