High-pressure spray type underwater wire-cloth washing machine

Abstract

The invention discloses a high-pressure jet-type underwater net washing machine, which comprises: a high-pressure chamber with an inclined high-pressure nozzle and a cavity inside, a frame for retaining, and a high-pressure conduit shaft with a water flow channel inside, wherein, The high-pressure catheter shaft is "T"-shaped, its radial end is connected to the high-pressure chamber, and its axial end is rotatably connected to the center of the frame; the water flow channel inside the high-pressure catheter shaft communicates with the cavity of the high-pressure chamber. The high-pressure water in the high-pressure water pipe flows through the water flow channel inside the high-pressure conduit shaft, enters the high-pressure chamber, and is sprayed out from the high-pressure nozzle installed obliquely on the high-pressure chamber. The reaction force of the high-pressure water jet makes the high-pressure chamber rotate and drives the nozzle on it to rotate. , so as to spray out the rotating high-pressure water flow, increase the cleaning area of ​​the net clothes, improve the cleaning efficiency, and the operation is simple and safe.

Description

technical field [0001] The invention relates to a net washing machine, in particular to a high-pressure jet-type underwater net washing machine for cleaning underwater culture cages. Background technique [0002] In recent years, due to the destruction of the marine ecological environment and the pollution of cage culture itself, the cages are easily attached by some fouling organisms, which not only shortens the life of the nets, but also has a great impact on management and culture. On the one hand, the attachment of fouling organisms reduces the amount of water exchange inside and outside the cages, resulting in a poor aquaculture environment, thereby reducing the growth rate and survival rate of farmed fish, and easily inducing diseases; on the other hand, fouling organisms The attachment of the net greatly increases the resistance of the net clothing, prompting the net clothing to drift under the action of the ocean current, and while causing a significant reduction in ...

AI Technical Summary

Problems solved by technology

[0003] At present, the method to solve the above problems is to carry out the cleaning operation of attached organisms when the nets are manually replaced, but the nets full of fouling organisms bring great difficulties to the operation of changing the nets, not only need to invest more manpower, but also The process of changing the net will also cause a certain degree of abrasion to the fish body

For example: a perimeter of 40m, a height of 6m, and a side area of ​​about 200m 2 After three months in the seawater, the total weight of the nets attached to fouling organisms can reach 1 ton. However, manual replacement of the nets and cleaning operations under the existing conditions have the following disadvantages: high labor intensity , long operating time, poor personal safety, and the cultured fish will suffer from a large degree of abrasion due to the long time of changing the net in the cage
