Cleaning device for aquaculture net cage

Abstract

The invention relates to a cleaning device for an aquaculture net cage and discloses a device which is mounted in the bottom of the net cage to clean net threads and meshes in the bottom of the net cage by matching a group of blades with a plurality of supporting plates. The cleaning device is characterized in that one ends of a plurality of connecting rods are placed on a fixed ring in an equallyspaced manner while mounting holes are formed in the other ends of the connecting rods; a fixed plate is placed in the fixed ring, and the outer side of the fixed plate is connected to the inner sideof the fixed ring through a plurality of fixed rods; the included angles between adjacent two fixed rods are equal; the fixed plate is of a round platy structure; the fixed plate is made from a rigidmaterial, and an anti-rust coating is arranged on the surface of one side; a driving motor is placed on the other side of the fixed plate, and one end of a motor shaft penetrates through the fixed plate through a sealing bearing; a protective hood is arranged on the outer side of the driving motor; the protective hood is made from a rubber material; a connecting sleeve is arranged on one end of the motor shaft in a sleeving manner; the group of blades is arranged on the outer side of the connecting sleeve; and the blades are of arc-shaped structures, and the heights of the blades are gradually decreased from one sides to the other sides.

Description

technical field [0001] The invention relates to an aquaculture net cage cleaning device, which relates to a device for cleaning the bottom of the aquaculture net cage, and belongs to the field of aquaculture. In particular, it relates to a device installed at the bottom of the net cage to clean the network cable meshes at the bottom of the net cage through the cooperation of a group of blades and a plurality of support plates. Background technique [0002] At present, in the aquaculture industry, aquaculture is often carried out in captivity in lakes, reservoirs and shallow seas. Cages are widely used as common aquaculture tools. Usually, the mesh aperture of the box is not too large. When feeding, the farmers directly throw fish food from the upper end of the box into the box, and part of the fish food will naturally sink under the action of gravity or follow the water flow. It flows out from the mesh on the side wall of the cage. In order to ensure that the fish in the ca...

[0002] At present, in the aquaculture industry, aquaculture is often carried out in captivity in lakes, reservoirs and shallow seas. Cages are widely used as common aquaculture tools. Usually, the mesh aperture of the box is not too large. When feeding, the farmers directly throw fish food from the upper end of the box into the box, and part of the fish food will naturally sink under the action of gravity or follow the water flow. It flows out from the mesh on the side wall of the cage. In order to ensure that the fish in the cage can eat enough food, the breeder usually puts too much fish food into the cage. Too much fish food cannot be eaten by the fish in time. The excrement mixed with fish is adsorbed on the bottom of the net cage, which will block the mesh at the bottom of the net cage. Long-term deposition will easily cause damage to the water quality in the box and affect the growth of fish. Because the net cage sinks in the water, it is difficult to locate the bottom of the net cage. After cleaning, the commonly used cleaning method is to salvage the fish in the net cage from the water and disassemble it for cleaning. Salvaging and dismantling will
