Oxygen increasing device of aquaculture pond

Abstract

The invention discloses an oxygen increasing device of an aquaculture pond. The device comprises a shell body, wherein the outer wall of the front of the shell body is provided with a motor, a rotating shaft in rear of the motor is provided with a crank, the oxygen increasing device of the aquaculture pond can push a dovetail block under a mounting plate into a dovetail groove in a supporting plate to make the dovetail block embedded into the dovetail groove to limit the vertical movement of the dovetail block, then a vertical insertion plate is inserted into an insertion groove in the supporting plate for embedment above the mounting plate by using the elasticity of contraction of a tension spring to limit the lateral movement of the insertion plate, through combination and limiting, thestability of the oxygen increasing device is greatly improved, and the assembly and disassembly are also very convenient; a sliding block in the device performs reciprocating motion under a crank connecting rod, the sliding block drives a screw sleeve to achieve forward and backward rotation movements and drives blades of a stirring plate to rotate, an air pipe of an aeration pump is leaded into the screw sleeve, and the blades stir water mixed with air, thereby increasing the fluidity of the oxygenated water, and greatly improving the evenness of oxygen amount in the aquaculture pond.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to an aeration device for aquaculture ponds. Background technique [0002] Aquaculture is the production activity of breeding, cultivating and harvesting aquatic animals and plants under human control. It generally includes the whole process of growing aquatic products from seedlings under artificial breeding management. In a broad sense, it can also include the proliferation of aquatic resources. Aquaculture devices generally include aquatic sites, feeding devices, aeration devices, and water purification devices and sterilization devices for special occasions. There are still some deficiencies in the process of use. [0003] The current aeration devices for aquaculture ponds have various shapes and structures, and most of them are installed on the support plate on the aquaculture pond by bolts. Although the installation is tight, the holes and pre-tightening are ...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a kind of aquaculture pond aeration device, to solve the present aquaculture pond aeration device that proposes in the above-mentioned background technology shape and structure are various, mostly be installed on the support plate on the aquaculture pond by bolt, although The installation is tight, but the hole and pre-tightening are very cumbersome. At the same time, the bolts are easy to rust if they are stained with water, and it is inconvenient to disassemble. Most of the general aeration devices are realized by introducing air into the water through the aeration pump, but the efficiency is relatively low. And it can't diffuse the oxygen-containing water well, and through the rotation of the blades, the water drops and air are mixed and poured into the pool for aeration, but the fluctuations in the water are relatively large, which affects the fish in the water. Activities in the water; and generally, when feeding materials, a separate device needs to be installed, which greatly increases the problem of operating costs
