Description

Underwater cleaning device and underwater cleaning system

Technical Field

The embodiment of the application relates to the technical field of underwater cleaning, in particular to an underwater cleaning device and an underwater cleaning system.

Background

Because a large number of shipping companies and shippers have no cargo source, the ships can only wait for voyage orders at the anchor. Because the ship is sailed or anchored in the marine environment with strong corrosiveness and strong adhesive force for a long time, normal maintenance is difficult to carry out, so that the parts below the waterline of the ship body are adhered with barnacles, oysters, bryozoans, huperzia serrata, lime worms, seaweed and other marine organisms, some rusts, rusty spots and the like which are difficult to remove. Thus, the surface smoothness of the ship body and the dead weight of the ship body are greatly influenced, the resistance is obviously increased when the ship advances in water, the ship speed is reduced, the fuel consumption is obviously increased, and the carbon dioxide emission is increased. It is estimated that the fuel consumption of the hull increases with the increase of the surface roughness due to the attachment of marine organisms, and the performance of the ship decreases. In addition, the marine attachment consumes 40% more fuel as soon as the ship speed is reduced by 10%. In addition, marine attachments can influence the safe operation of ships and even cause accidents because of being attached to parts such as a propeller, a sonar, a propeller shaft and the like. Therefore, the removal of marine attachments plays an important role in the safe operation of ships and the reduction of energy consumption. The cost of cleaning marine attachments per year spent on the global marine vessels, offshore drilling platforms and other offshore facilities is statistically high in the hundreds of billions of dollars, and huge market demands exist.

Most of the existing technologies for cleaning underwater polluted garbage are manually cleaned by using a physical friction mode or high-pressure water mixed gravel, and cannot cope with complex cleaning working conditions and complex surface conditions, such as a 3D special-shaped curved surface structure, so that the cleaning efficiency is greatly reduced and even the cleaning effect cannot be achieved.

The nozzle plate 302 is provided with three evenly-distributed self-whirling nozzles, when high-pressure water is absorbed into the nozzle plate 302 to drive the through shaft 304, the thrust bearing 307 and the angular contact bearing 308 to whirl at a high speed, and the three rotating nozzles form a cavitation plate body cleaning face. The retention wheel assembly 4 is threadably coupled to the nozzle plate 302 along with the shield plate. The structure of the retaining wheel assembly 4 is as shown, the bearing seat 401 is in threaded connection with the end cover, and the vertical shaft 404 penetrates through the end cover, is provided with a aligning thrust bearing 403 inside the bearing seat 401 and is provided with a rotary seal. The small wheel is driven to rotate along with the shaft by the threaded connection of the holding wheel frame 405 and the shaft. The cross shaft 406 is in threaded connection with the holding wheel frame 405, and the cross shaft 406 is provided with a deep groove ball bearing 407 and a small wheel. The holding wheel assembly 4 is a two degree of freedom universal wheel mechanism.

The cleaning assembly 3 works as follows, high-pressure jet water is injected into the cleaning assembly and the nozzles cavitate to strike the cleaning surface, the cleaned and peeled garbage is crushed into a large volume of garbage by the crushing assembly 5 along the inner side of the recovery guide in a relatively closed space surrounded by the recovery cover 2 and the flexible cover, the large volume of garbage is sucked by a garbage recovery pipe of the recovery system, and meanwhile, the rotating nozzle disc 302 enables the cleaning surface to form vortex negative pressure, and the nozzle disc 302 is protected by the nozzle shield 305 and the protection plate to work normally. When the roller 402 moves to the non-planar or non-flat garbage, the holding wheel assembly 4 pushes the nozzle disc 302 upwards to drive the through shaft 304 to compress the built-in cleaning spring 306, so that the nozzle disc 302 can float upwards, the relative distance between the cavitation outlet of the nozzle and the cleaning surface is ensured, and the cleaning efficiency of the air jet is optimal. And at the same time, the integral cavitation plate is driven to float.

The embodiment of the application has at least the following beneficial effects:

1. the device has high efficiency, the maximum cleaning rate can exceed 1500 square meters per hour, the device is suitable for cleaning different shapes of different materials in a large range, the ship does not need to be stopped for docking, the construction operation can be carried out on a quay or a ship anchor, the construction time is short, and the device is also suitable for the surface of a platform or a device fixed on the sea;

2. the safety performance is improved, the water flow can not damage unprotected paint and varnish anti-scaling and anti-corrosion coating of the ship body, and simultaneously, the cavitation jet flow adopts seawater or fresh water as a medium, so that the pollution is effectively reduced;

3. the cavitation jet technology is suitable for all types of cleaning technology, can be applied to cleaning the surfaces of steel, concrete, wood and strong plastic substances, and can be used for efficiently cleaning pollutants attached to the surfaces of the steel, concrete, wood and strong plastic substances.

4. Cavitation jet cleaning equipment is various, and the large-scale nozzle disc 302 can be used for cleaning the regular surface, and simultaneously the cavitation gun can be used for cleaning smart components such as a submarine valve and the like, so that a propeller is cleaned, polished and polished to form a smooth surface, the attachment of marine organisms is reduced, and the cleaning frequency is reduced.

5. The underwater cleaning device provided by the embodiment of the application can work in a severe working environment with a large attached garbage volume. The four cleaning assemblies 3 are arranged in the whole recovery cover 2, so that the influence on the normal rotation of the spray head when the garbage moves is not easy to happen. The recycling pipe sucks away after crushing the large-volume garbage through the crushing assembly 5, so that the garbage recycling efficiency can be improved, and the probability of equipment garbage recycling and anchoring under severe working conditions is reduced: the probability of secondary pollution of the ocean garbage to the sea environment is reduced.
