Oxygen supplementing device for cultivating gymnocypris chilianensis

Abstract

The invention discloses an oxygen supplementing device for cultivating gymnocypris chilianensis, and belongs to the technical field of carp cultivation. The oxygen supplementing device comprises an air guide ring, the top end of the air guide ring is provided with an air inlet, the bottom of the air guide ring is disconnected from an oxygenating device, the bottom end of the oxygenating device isprovided with an anti-sinking transverse plate, and the left end of the anti-sinking transverse plate is provided with a water inlet; a water outlet is formed in the right end of the anti-sinking transverse plate, axial fans are arranged in the water inlet and the water outlet, the water inlet and the water outlet are communicated through a flow guide pipe, a weight is arranged at the bottom end of the anti-sinking transverse plate, the center of the top end of the oxygenating device is communicated with an aeration hose, and aeration openings are formed in the joints of the aeration hose andthe flow guide pipe; and a stirring paddle is arranged between every two adjacent groups of aeration openings, sterilization devices are arranged at the positions, close to the water inlet and the water outlet, of the flow guide pipe, the outer wall of the air guide ring is slidably sleeved with two groups of mutually symmetrical sliding blocks, and the sliding blocks are connected with a floatingball. By means of the oxygen supplementing device, oxygen supplementing can be achieved, propagation of aerobic microorganisms is effectively inhibited in the oxygen supplementing process, and the aerobic microorganisms are from infecting seedlings.

Description

technical field [0001] The invention relates to the technical field of carp cultivation, in particular to an oxygen supplement device for naked carp cultivation in Qilian Mountains. Background technique [0002] The naked carp in Qilian Mountains is a fish on the Qinghai-Tibet Plateau. It is distributed in Qinghai Lake and its tributaries. It is also produced in Crook Lake, Zhaling Lake, and Ering Lake. It is an extremely important economic fish in Qinghai Province. Since the 1960s Hundreds of thousands of acres of grasslands around Qinghai Lake have been reclaimed as farmland, and many rivers flowing into Qinghai Lake have been dammed artificially to block breeding channels. which died in the estuary; [0003] When artificially breeding this fish species, it is necessary to supplement oxygen to the water body to ensure that the survival rate of the seedlings is improved. , fungi, etc. reproduce quickly, which will cause infection to the seedlings, reduce the survival rate...

AI Technical Summary

Problems solved by technology

[0003] When artificially breeding this fish species, it is necessary to supplement oxygen to the water body to ensure that the survival rate of the seedlings is improved, but when supplementing oxygen in the water, the high concentration of oxygen The content will also promote the large-scale reproduction of aerobic microorganisms in the water body, resulting in faster reproduction of bacteria and fungi, which will cause infection of seedlings, reduce the survival rate of seedlings, and is not conducive to the healthy growth of seedlings. In order to breed seedlings, both It can achieve the effect of supplementing oxygen and effectively inhibit the reproduction of microorganisms. We propose an oxygen supply device for the cultivation of naked carp in Qilian Mountains.
