Underwater netting cleaning robot through cavitating jet

Abstract

The invention discloses an underwater netting cleaning robot through cavitating jet, and mainly relates to the field of underwater attached marine creature cleaning. The robot comprises a chassis, a walking mechanism, a controller, a video monitoring probe, a propeller and a rotary cleaning head, wherein the chassis is used for installing the walking mechanism, the controller, the video monitoringprobe, the propeller and the rotary cleaning head, the walking mechanism is used for driving the robot to move on a hanging net, a power transmission device is used for providing power for the walking mechanism, the video monitoring probe is used for collecting image information around the robot, the propeller is used for pushing the robot to be attached to the hanging net, the rotary cleaning head is used for generating high-pressure water containing cavitation bubbles, and the walking mechanism is arranged on the chassis, the propeller is arranged on the side edge of the chassis, and the rotary cleaning head is arranged below the chassis. The robot has the beneficial effects that the cavitating jet is adopted as a cleaning mode, so that the netting cleaning can be completed through a net cage in a breeding state.

Description

technical field [0001] The invention relates to the field of cleaning underwater attached marine organisms, in particular to a cavitation jet underwater net cleaning robot. Background technique [0002] The ocean occupies 71% of the earth's surface. China has a long coastline and is rich in offshore and deep sea resources. In recent years, the scale of my country's offshore and deep-sea aquaculture industry has become larger and larger. From traditional cages to special cages, from aquaculture platforms to aquaculture workboats, various marine aquaculture technologies have been rapidly developed and applied. The aquaculture industry has always been faced with the problem of attached biological pollution. Whether it is a cage or a breeding platform, whether it is in the offshore or in the deep sea, all parts immersed in the water are extremely vulnerable to marine organisms. Seaweed, shellfish and other marine organisms will clog the mesh after they attach and breed, which w...

AI Technical Summary

Problems solved by technology

After seaweed, shellfish and other marine organisms attach and grow, the mesh will be blocked, which will reduce the oxygen content of the water body in the breeding area, reduce the fluidity of the water body, and cause a large number of breeding organisms to die

The marine organisms attached to the breeding platform or farming boat also increase the load of the facility, reducing the stability and storm resistance. The nets covered with marine organisms will also increase the water flow resistance, making the storm resistance of the nets sharply reduced. Decline, the storm will cause great economic losses

[0003] The traditional cleaning method mainly relies on manual dragging to the shore and drying or high-pressure water washing, which consumes a lot of manpower and material resources, takes a long time to clean, and needs to wait until there are no cultured animals in the net.

Another method is to send divers into the water to wash the cages every few days to prevent the attachment and growth of marine organisms on the nets. Difficult to remove, efficient and low cost
