Description

A kind of propeller underwater cleaning device
Technical field
The present invention relates to cleaning device technical field, especially a kind of propeller underwater cleaning device.
Background technique
Currently, power vessels are all to make ship's navigation, the promotion effect of propeller by sustainer driving propeller Rate has large effect to the route speed of ship.Ship's navigation after a certain period of time, propeller surface can adsorb dirt, Dirt increases the frictional force between propeller blade and water, overcomes these frictional force inevitable when such propeller high speed rotation More energy is consumed, caused final result is the slack-off route speed of ship, oil consumption increase, operation costs increase.It is now anxious A kind of propeller cleaning method of need and device provide technology for the decontamination of propeller for vessels surface and equipment are supported.
In the prior art, there are mainly three types of the main methods and device that propeller cleans:
(1) after ship drydocking, worker holds scoop, brush etc. and is manually removed the dirt on propeller surface, Then it is washed away with high pressure water.Cleaning effect is best, but the time that ship is parked in dock is longer, into dock, artificial, pause operation Etc. factors considerably increase shipping cleaning expense.This cleaning method is usually used when ship is into dock repair.
(2) ship rests on the water surface, and diver holds cavitation jet system and sprays under water to the dirt on propeller surface Penetrate cavitation bubble, the energy that when bubble collapse generates degrades the dirt on propeller surface.Diver is lauched operation and increases spiral shell The cost of labor of paddle cleaning is revolved, and underwater control unknown risks factor is more, constitutes a threat to the inherently safe of diver.
(3) ship rests on the water surface, and ultrasonic transmitter is launched near underwater propeller, is issued using it Ultrasonic wave is by the dirt removal on propeller surface.Ultrasonic cleaning it is high-efficient, but have serious destruction to marine environment.
Summary of the invention
The applicant provides a kind of structurally reasonable propeller underwater cleaning for the disadvantage in above-mentioned existing production technology Device so as to realize that the complex surface to ship, submarine propeller etc. is effectively cleaned under water, and is not necessarily to diver It is lauched operation.
The technical solution adopted in the present invention is as follows:
A kind of chassis inside propeller underwater cleaning device, including underwater robot ROV, the underwater robot ROV On straight line mould group is installed, the driving sliding block slid along is installed, and drive in the straight line mould group by the first waterproof machine It is dynamic;The one end underwater robot ROV top is fixedly installed with cavitation jet device rear base, the cavitation jet device rear base side Portion connects push rod one end by first axle, and the push rod other end is connect by second hinge with driving sliding block;The cavitation jet Triangle supporting plate is extended on the outside of device rear base, leading screw bearing, the lead screw are installed in the cavitation jet device rear base top Lead screw is passed through in the middle part of support, and the second waterproof machine of driving lead screw rotation is installed on the cavitation jet device rear base, it is described Lead screw extend out to the outside of underwater robot ROV, and feed screw nut is installed outside it, and the feed screw nut is fixed on support frame On, support frame as described above is mounted on crossover sub, and there are three support frame, other two supports for the circumferencial direction distribution of crossover sub Frame head passes through linear guiding axis, and the head of both threads guiding axis and lead screw is equipped with the cavitation jet device parallel with supporting plate The tail portion of front-end bracket, both threads guiding axis is mounted on supporting plate by third hinge;In the middle part of underwater robot ROV also Flexible water conduit is installed, the head of the flexible water conduit is equipped with cavitation jet spray head by transition components.
Its further technical solution is:
The cavitation jet device front-end bracket is at semi-annular structure, and lead screw and both threads guiding axis are in space at triangle Shape distribution.
The outside of cavitation jet device front-end bracket is stretched out on the head of lead screw and both threads guiding axis, and by sealed Bearing, shaft block ring and hole retaining ring are connect with the mounting hole of cavitation jet device front-end bracket, cavitation jet device front end branch The outer end face of frame installs cushioning supportive bar by locking nut or the first screw, and buffering is installed on the head of the cushioning supportive bar Block.
The mounting structure of the transition components are as follows: flexible water conduit head passes through flexible hoop tube adaptor coupling adapter, It is extended with rotary table in the middle part of the crossover sub, support frame there are three installations is spaced on the rotary table, passes through method on support frame as described above Flange-type linear bearing installs linear guiding axis;Described crossover sub one end cavitation jet spray is installed by sealing ring and guide collar The inner face of head, the cavitation jet spray head installs end cap by the second screw.
Beneficial effects of the present invention are as follows:
Structure of the invention is compact, reasonable, easy to operate, is driven by lead screw and spray head realization is driven to be moved forward and backward, while The front end of spray head greatly improves functional reliability by the effect of installation buffer stopper, and safety coefficient is high.
Propeller underwater cleaning device volume of the present invention is small, and ship is easy to carry, and ship is parked on the water surface, by spiral shell Rotation paddle underwater cleaning device can clean propeller for vessels after being put into water, avoid ship into the high cost of dock and Diver is lauched the high risk of operation, and does not destroy marine environment.
Three high elastic rubber buffer stoppers can stick on the complex surface of propeller, and avoid underwater robot Impact force between ROV and propeller protects propeller, substantially increases the resistance to of underwater robot ROV and cavitation jet system With property, and high elastic rubber buffer stopper is readily replaceable.
Cavitation jet system avoids personnel from being lauched cleaning propeller in conjunction with underwater robot ROV, cavitation jet spray head Using hingedly making cavitation jet spray head realize multi-angle injection between pedestal and underwater robot ROV, lead screw penetrates cavitation It flows the spray distance between spray head and object propeller to be easy to adjust, obtain any position on propeller curved surface can clearly It washes.
Cavitation jet spray head is degraded using dirt of the cavitation bubble to propeller surface, and cavitation jet spray head generates Recoil be that couple rotates spray head, the projected area of spray head is increased, and recoil is balanced, underwater Headlamp and camera on people ROV provide cleaning picture in real time for the operator on deck.
