Embodiment Construction

[0021] The technical solutions of the present invention will be further specifically described below through the embodiments and in conjunction with the accompanying drawings.

[0022] Such as Figure 1 to Figure 3 As shown, the underwater network washing disk of the present invention includes an annular outer protective frame 14, and the top of the annular outer protective frame 14 is fixed with a plurality of annular grids 6 through the radial rear bracket 5; specifically, the radial Backward support 5 is L-shaped, and an arm of this L-shaped rear support 5 is riveted with the inner wall of the ring-shaped outer protective frame 14 by screws, and the other support arm of this L-shaped rear support 5 extends radially to the circle. The top center of the ring-shaped outer protection frame 14 is fixedly connected with the flange 4 located at the top center of the ring-shaped outer protection frame 14 .

[0023] The flange 4 is connected with a water slip ring 1, and the interi...

Abstract

The invention discloses an underwater net washing disk, comprising an annular outer protective frame (14), a flange plate (4), a water slip ring (1), and a high-pressure conduit shaft (3). The bottom of the water slip ring (1) is rotatably provided radial manifold branches (10). The tail ends of the manifold branches (10) are provided with high-pressure nozzles (12) arranged in an inclined manner. The back surfaces of the manifold branches (10) are also provided with radial turn-out blades (9). The internal of the water slip ring (1) is provided with an axial center hole (2), and the hole is communicated with the high-pressure conduit shaft (3) and the manifold branches (10). Through rotation of the plurality of manifold branches and the blades, cleaning of a netting is realized, so as to reduce structural weight and increase simplicity of manufacturing and installation. Components are modularized, and component changing and maintenance are easy. In addition, the turn-out blades are arranged along the radial direction of the manifold branches, and the turn-out blades have large water absorption area, so as to reduce pressure loss and improve cleaning capability.

Description

technical field [0001] The invention relates to a net washing device for aquaculture net cages, in particular to an underwater net washing disk. Background technique [0002] In recent years, due to the destruction of the marine ecological environment and the pollution of the cage culture itself, the cages are easily attached by some fouling organisms, which not only shortens the life of the nets, but also brings great negative impacts on management and cultivation . On the one hand, the amount of water exchange inside and outside the cage is reduced, and the breeding environment is deteriorated, which affects the growth rate and survival rate of the cultured fish, and is easy to induce diseases; Drift under the action of nets will greatly reduce the breeding volume, and at the same time, the friction between the nets will also cause mechanical damage to the breeding objects. Therefore, any fouling organisms attached to the cages need to be promptly removed. [0003] At p...
