An underwater cleaning device for aquaculture cages

technical field

The invention relates to an underwater cleaning device for aquaculture cages, which is mainly used for cleaning attachments on nets of seawater aquaculture cages, and belongs to the technical field of fishery farming machinery.

Background technique

Mariculture cages soaked in water for a long time, because the net material itself is non-toxic and has a large surface area, it is conducive to the rapid growth of a large number of filamentous algae and other attachments, resulting in mesh blockage, resulting in reduced water filtration performance of the cage, making the net Poor water flow in the tank leads to a decrease in dissolved oxygen, resulting in frequent occurrence of fish diseases and a decline in the quality of farmed fish. In addition, a large number of biological attachments will increase the weight and frontal area of the nets, increase the force load on the nets, and seriously cause damage to the nets; therefore, during the breeding process, it needs to be replaced continuously with the growth of the fish body. Net clothes and clean the attachments on the nets in time to avoid excessive attachments that increase the weight of the cage and hinder water exchange. In the prior art, many units have studied the net cage cleaning device, and some prototypes have come out, but there are situations such as low cleaning efficiency and difficult operation. Up to now, no suitable net cage cleaning device has been widely used in production. , It is still mainly cleaned by traditional high-pressure water guns or diving manual brushes.

Contents of the invention

The technical problem to be solved by the present invention is: the existing cleaning equipment for aquaculture net cages has low cleaning efficiency and difficult operation, so the prior art still mainly uses traditional high-pressure water guns or diving artificial brushes for cleaning.

The present invention takes the following technical solutions:

An underwater cleaning device for aquaculture net cages, comprising: a rotary shaft 6, the rotary shaft has a central blind hole, and the rotary shaft is provided with at least one water inlet connected to the central blind hole along the radial direction; a shaft sleeve 7, the The shaft sleeve 7 is fixedly arranged on the outside of the rotary shaft 6, a ring groove is provided on the inner wall of the shaft sleeve corresponding to the water inlet, and a water inlet hole connected to the ring groove is provided on the side wall of the shaft sleeve. The hole is connected with the submersible pump; the cleaning plate 1, a number of branch pipes 2 are evenly arranged on the cleaning plate, and the ends of the branch pipes are connected to the nozzles 3; The water on the top produces the reaction force of rotation to cleaning disc 1.

Further, the horizontal included angle is 30-50°.

Furthermore, the horizontal included angle is 40°.

Further, the number of the water inlets is 2, and they are arranged symmetrically.

Further, two bearings 10 and 11 are arranged separately in the middle of the rotating shaft 6 .

Further, sealing covers 8 and 12 are installed on the outside of the bearing respectively.

Further, the outer side of the shaft sleeve 7 is fixedly connected with the casing 4, and the operating rod 5 is installed on the casing.

The beneficial effects of the present invention are:

1) The structure is simple and the operation is convenient, which ensures the environment of the cage culture and improves the quality of the breed;

2) The structure design of the rotary shaft and the shaft sleeve is ingenious, and the reliability is high;

3) The nozzle adopts inclined setting, and the reaction force of the sprayed water is used to drive the cleaning disc to rotate. The design is ingenious, the cleaning effect is good, the cleaning efficiency is high, and the degree of automation is high;

4) The operating rod is used as auxiliary power, which is thoughtful.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

Referring to Figures 1-4, an underwater cleaning device for aquaculture cages, including: a rotary shaft 6, the rotary shaft has a central blind hole, and the rotary shaft is provided with at least one water inlet communicating with the central blind hole along the radial direction Shaft sleeve 7, the shaft sleeve 7 is fixedly arranged on the outside of the rotary shaft 6, a ring groove is provided on the inner wall of the shaft sleeve corresponding to the water inlet, and a water inlet connected to the ring groove is provided on the side wall of the shaft sleeve hole, the water inlet hole is connected to the submersible pump; cleaning plate 1, a number of branch pipes 2 are evenly arranged on the cleaning plate, and the end of the branch pipe is connected to the nozzle 3; the water outlet direction of the nozzle 3 has a horizontal angle with the end surface of the cleaning plate , make the water that is sprayed on the net box produce the reaction force of rotation to cleaning disc 1.

In this embodiment, the horizontal included angle is 30-50°.

In this embodiment, referring to FIGS. 3-4 , the horizontal included angle is 40°.

In this embodiment, the number of the water inlets is two, and they are arranged symmetrically.

In this embodiment, referring to FIG. 1 , two bearings 10 , 11 are arranged separately in the middle of the rotary shaft 6 .

When the cage net clothes need to be cleaned, through the high-pressure water pump, the seawater enters from the water inlet hole of the shaft sleeve 7, and enters the three branch pipes 2 through the through hole in the center of the rotary shaft. Under the reaction force, the cleaning disc produces a rotary motion, which drives the rotary shaft to rotate in the shaft sleeve. Under the action of high pressure, the rotating sprayed water produces a great impact, which can effectively clean off the attachments on the netting and ensure the health of the breeding water. , Improve the level of breeding management.

The above are the preferred embodiments of the present invention. Those skilled in the art can also make various transformations or improvements on this basis. Under the premise of not departing from the general concept of the present invention, these transformations or improvements should all belong to the claims of the present invention. within the range.
