Underwater cleaning device and underwater robot system

Abstract

The invention discloses an underwater cleaning device and an underwater robot system. The underwater cleaning device comprises a cleaning device inner cavity; one end of the cleaning device inner cavity is connected with an external high-pressure rubber pipe through a first rotary joint, and high-pressure water is injected through the external high-pressure rubber pipe; the other end of the cleaning device inner cavity is connected with a cavitation jet rod through a second rotary joint; rotation of the first rotary joint and rotation of the second rotary joint do not interfere with each other; a first fixed pipe is coaxially arranged outside the first rotary joint, and a second fixed pipe is coaxially arranged outside the second rotary joint; a cleaning disc is fixedly connected between the first fixed pipe and the second fixed pipe, an opening of the cleaning disc faces one side of the cavitation jet rod, and the cavitation jet rod is located in the opening of the cleaning disc. According to the cleaning device, the underwater robot clamping operation can be carried out to carry out underwater automatic cleaning operation, the manual labor intensity is greatly relieved, and attached marine organisms and dirt can be safely and efficiently removed.

Description

technical field [0001] The invention relates to the technical field of underwater cleaning devices, in particular to an underwater cleaning device and an underwater robot system. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Ships, platforms, and pipelines that have been in seawater for a long time are generally eroded and polluted by algae, barnacles, and molluscs. In general, due to the attachment of marine microorganisms, ships consume more fuel, which increases transportation costs. At the same time, the dirt attached to the hull, valves and propellers will greatly reduce their working efficiency. Marine organisms will also erode the protective layer on the surface of the equipment and accelerate the corrosion rate of the equipment. Marine attachments increase the load on the structure, reduce the stability of the facility, and ma...

AI Technical Summary

Problems solved by technology

If the net cage is soaked in seawater for a long time, there will be a lot of sea creatures, algae, shellfish, etc. attached to the net cage, which will easily cause the mesh to be blocked, so that a large amount of feces and residual bait of the fish cannot be discharged, hindering the water exchange of the net cage, and causing the fish to be farmed. lower class quality

In addition, the aggravation of net clothing attachments in the cage will also increase the overall weight of the cage, increase the resistance of the cage, and seriously affect the safety and service life of the cage

[0005] The inventor found that the current underwater cleaning method often uses artificial diving to hold some cleaning devices, which is labor-intensive, dangerous, poorly sealed, and has a high failure rate. It is easy to damage the original coating or material, and it is difficult to clean various targets. , such as the bottom surface of the ship, the net clothing of the breeding cage, etc.

The internal pressure of the high-pressure cleaning device is relatively large, and steel parts are often used, which have a certain weight in the water, which will affect the buoyancy performance of the device in the water, which is not conducive to the normal and effective operation of the device
