Description

Technical Field

[0001] The utility model relates to the technical field of fishery breeding, in particular to a fishery breeding oxygen pump. Background Art

[0002] An aerator is a machine commonly used in fishery farming. Its main function is to increase the oxygen content in the water to ensure that the fish in the water will not be short of oxygen. It can also inhibit the growth of anaerobic bacteria in the water and prevent the pond water from deteriorating and threatening the living environment of fish. An aerator generally relies on its own air pump to pump air into the water to increase the oxygen content in the water. An aerator is a device that uses a power source such as an electric motor or a diesel engine to drive the working parts to quickly transfer oxygen in the air to the aquaculture water.

[0003] Traditional oxygen pumps have the following defects: the oxygen flow rate discharged by the oxygen pump cannot be adjusted, resulting in the inability to control the amount of oxygen entering the water body, resulting in excessive oxygen, which affects the cultivation of fishery products.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] See also Figures 1 to 4The utility model provides a technical solution: an oxygen pump for fishery breeding, comprising an oxygen pump body 1, an air outlet nozzle 2 fixed at the end of the oxygen pump body 1, an air supply hose 8 plugged in and unpluggedly connected to the air outlet nozzle 2, and an aeration head 9 plugged in and unpluggedly connected to the other end of the air outlet nozzle 2, the aeration head 9, that is, an air bubble stone, is used to add oxygen to the water body. By starting the oxygen pump body 1, the generated oxygen is discharged into the water body through the air supply hose 8 and finally through the aeration head 9 to achieve oxygenation.

[0022] A positioning block 3 is fixedly connected to the end of the oxygen pump body 1. A positioning hole 301 is provided on the surface of the positioning block 3. The lower end of the gas hose 8 is arranged through the positioning hole 301. A plug hole 302 is provided at the end of the positioning block 3. A clamping rod 4 is movably inserted inside the plug hole 302. A guide assembly 5 is fixedly installed on the side wall of the positioning block 3. One end of the guide assembly 5 is connected to the clamping rod 4. The position of the clamping rod 4 can be adjusted through the guide assembly 5, so that the clamping rod 4 can clamp the gas hose 8.

[0023] The guide assembly 5 includes a guide sleeve 53 fixed to the side wall of the positioning block 3 , an insertion strip 52 movably inserted in the guide sleeve 53 , and a base block 51 fixed to the end of the insertion strip 52 . The end of the pressing rod 4 is fixedly connected to the base block 51 .

[0024] When using the device, one end of the gas hose 8 is inserted into the gas outlet nozzle 2, and the other end of the gas hose 8 is inserted into the positioning hole 301. By pushing the base block 51, the insert 52 can move linearly inside the guide sleeve 53, and at the same time, the base block 51 and the clamping rod 4 are close to the gas hose 8. The clamping rod 4 and the gas hose 8 are abutted to compress the gas hose 8, so that the gas flow through the gas hose 8 becomes smaller, so that the oxygen discharged through the aeration head 9 is slower, avoiding the situation of excessive oxygen, maintaining the stability of water quality and avoiding the adverse effects of excessive or low oxygen concentration on organisms; appropriately adjusting the gas flow rate can control the size of the bubbles, making the bubbles more uniform, and improving the dissolution efficiency of oxygen in water.

The internal threaded sleeve 7 is in contact with the side wall of the guide sleeve 53 to lock the position of the insertion strip 52. Specifically, the surface of the guide sleeve 53 has a groove, and the stud 6 passes through the groove and can move linearly in the groove.

[0026] By screwing the internal thread sleeve 7 onto the stud 6 and making the end of the internal thread sleeve 7 contact the side wall of the guide sleeve 53, the position of the inserting strip 52 is locked, and the position of the pressing rod 4 is further locked.

[0027] In addition, the pressing rod 4 is a cylindrical structure, the insertion hole 302 is a circular hole, and the diameter of the insertion hole 302 is slightly larger than the diameter of the pressing rod 4 .
