An underwater cleaning device and underwater robot system

Abstract

The invention discloses an underwater cleaning device and an underwater robot system, comprising: an inner cavity of the cleaning device, one end of the inner cavity of the cleaning device is connected to an external high-pressure rubber hose through a first rotary joint, and a high-pressure rubber hose is provided through the external high-pressure rubber hose. water injection; the other end of the inner cavity of the cleaning device is connected to the cavitation spray rod through the second rotary joint; the rotation of the first rotary joint and the second rotary joint does not interfere with each other; the first rotary joint is coaxially arranged with a first A fixed pipe, a second fixed pipe is coaxially arranged outside the second rotary joint; a cleaning plate is fixedly connected between the first fixed pipe and the second fixed pipe, and the opening of the cleaning plate faces the side of the cavitation spray rod, The cavitation spray rod is located in the opening of the cleaning disc. The cleaning device of the present invention can be clamped and operated by an underwater robot to perform underwater automatic cleaning operations, which greatly reduces labor intensity and can safely and efficiently remove attached marine organisms and dirt.

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
