Description

Technical Field

[0001] The present invention relates to the technical field of ship maintenance, and in particular to a ship maintenance tool. Background Art

[0002] With the continuous advancement of shipbuilding technology and the rapid development of the shipbuilding industry, ship maintenance tooling will also develop in a more standardized, generalized, automated and intelligent direction. Ship maintenance tooling is a tool or equipment specially designed and manufactured to meet the needs of ship manufacturing, repair, maintenance, inspection and other work. It is an indispensable and important tool in ship maintenance work. The main purpose of these tools is to improve the efficiency and quality of ship maintenance work.

[0003] Generally speaking, when inspecting the bottom of a large ship, most of the time, simple tools such as wooden blocks are used to raise the ship entering the inspection dock. After the ship enters the dock, professional divers need to dive into the dim water to confirm and adjust the position of the tools. The work of divers is extremely dangerous and the accuracy of the tool position is not guaranteed, which greatly reduces the stability of the ship during inspection, making it very easy for the ship to capsize during inspection, thereby threatening the lives of divers and on-site staff. At the same time, it will also cause damage to the inspection dock and the ship being inspected, and the practicality is not good. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when the bottom of a large ship is inspected and repaired, accidents such as the ship tipping over are very likely to occur, which threatens the life safety of divers and on-site staff and also causes damage to the inspection dock and the ship being inspected. A ship inspection tool is proposed.

The ends of the multiple groups of hydraulic pipes connected to each group of tooling frames all penetrate the outer wall of the tooling frame and are respectively connected to the inside of rubber bag 1 and rubber bag 2. The end of a group of hydraulic pipes close to the dock command room, away from the tooling frame, is connected to the output end of the integrated suction hydraulic pump in the dock command room.

[0010] In the above-mentioned ship maintenance tooling, a plurality of groups of water inlet valves are evenly arranged on the dock gate.

[0011] In the above-mentioned ship maintenance tooling, the lifting assembly includes multiple groups of cylinders, which are evenly installed inside the base, and the output ends of the multiple groups of cylinders all penetrate the top wall of the base and are fixedly connected to the bottom ends of the two groups of tooling frames respectively.

[0012] In the above-mentioned ship maintenance tooling, the plurality of groups of oil cylinders are all made of stainless steel.

[0013] In the above-mentioned ship maintenance tooling, the driving assembly includes multiple groups of power wheels 2, and the multiple groups of power wheels 2 are respectively rotatably connected to both sides of the base. Guide grooves are symmetrically opened on both sides of the working groove. The multiple groups of power wheels 2 are respectively located in the two groups of guide grooves, and the outer side walls of the multiple groups of power wheels 2 are respectively in contact with the top walls and top walls of the two groups of guide grooves.

[0014] In the above-mentioned ship maintenance tooling, an ultrasonic generator is installed on the top of the dock gate to enable the ship passing above the ultrasonic generator to be affected by the acoustic and thermal effects.

[0015] The above-mentioned ship maintenance tooling also includes a cleaning mechanism, which includes a scraper.

One end of the two groups of water inlet pipes is respectively connected to the two groups of high-pressure water gun manipulators, and the other ends of the two groups of water inlet pipes pass through the outer wall of the base and are connected to the output end of the booster water pump in the dock command room.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The present invention can quickly lift large ships of different types entering the working tank through the arrangement of the ship maintenance mechanism, thereby facilitating the maintenance work on the bottom of the large ship, and when lifting the large ship, the center of gravity of the ship can be balanced, thereby ensuring the stability of the ship during maintenance, avoiding the ship from becoming unstable and causing a capsizing accident, and further protecting the lives of on-site personnel, providing a safer working environment for on-site personnel, and at the same time avoiding damage to the maintenance dock and the ship being maintained, saving maintenance costs.

[0020] 2. The present invention can use a suction integrated hydraulic pump to fill oil into the supporting component when lifting a large ship through the mutual cooperation of the supporting component and the oil supply component in the lifting assembly. Then, when the supporting component contacts the bottom of the ship and is squeezed, the supporting component is covered to adapt to the slight changes in the size and structure of the bottom of the ship and increase the force-bearing area, so as to adapt to large ships of different types during lifting. Then, the oil supply to the rubber bag one is stopped and the oil filling amount is maintained at 50%. At the same time, the ship is lifted by continuously supplying oil to the rubber bag two, and the internal pressure of all the rubber bags two is ensured to be the same, thereby ensuring the stability of the ship during lifting. At the same time, during use, if a rubber bag two fails or ruptures, the rubber bag one paired with it and maintaining 50% of the oil volume is immediately and quickly filled with oil to replace the failed rubber bag two in the same group, so as to prevent the ship from becoming unstable and tipping over, thereby further ensuring the stability of the ship during lifting.

[0021] 3. The present invention can also expose the part of the bottom of the ship that is pressed by the rubber bag 2 by filling the rubber bag 1 with oil to the pressure of the rubber bag 2 in the same group and slowly releasing the oil through the cooperation of the supporting components and the oil supply components in the lifting assembly after the exposed part of the bottom of the ship is cleaned, sandblasted and painted. This allows the maintenance personnel to perform maintenance, sandblasting and painting on the previously pressed area, thereby ensuring the integrity of the maintenance work. Meanwhile, during the period of filling the rubber bag 1 with oil, if the rubber bag 1 fails or ruptures, the rubber bag 2 in the same group that is releasing oil will immediately switch from the original oil release to oil supply until the original state is reached, thereby ensuring the safety of the personnel on site and preventing accidents.

[0022] 4. The present invention, through the mutual cooperation of the ultrasonic generator and the cleaning mechanism, can make the bottom of the ship heat up through the acoustic thermal effect when the ship enters the dock, so that the organisms attached to the bottom of the ship where the high temperature is generated, such as barnacles, mussels, oysters and the like, die under the sudden high temperature and denature the biological protein mucus that can be adsorbed on the bottom of the ship, thereby greatly reducing the adsorption force, and peeling off under the joint impact of the seawater vibration caused by the ultrasonic wave and the cavitation bubbles. After that, the remaining unpeeled bottom organisms are dropped off from the bottom of the ship one by one under the high-pressure water sprayed by the high-pressure water gun manipulator in the cleaning mechanism, thereby conveniently completing the cleaning of the attached organisms on the bottom of the ship.

[0023] 5. The present invention, through the arrangement of the cleaning mechanism, can flush the bottom wall and side walls of the working tank through the high-pressure water gun manipulator after all the ship maintenance work is completed, so that the dirt and some of the organisms re-attached to the working tank are peeled off from the working tank, and at the same time, the power wheel is controlled to move to drive the scraper to move. On the way forward, the scraper scrapes off the dirt on the bottom wall and side walls of the working tank and pushes it toward the dock command room. At the same time, under the action of the automatic reel, the water inlet pipe can be automatically retracted and released to ensure the supply of high-pressure water during movement, so that the dirt on the side wall can be flushed down, and finally all the dirt is pushed off the base by the scraper, eliminating the step of the staff to clean the bottom of the ship, improving safety while reducing the labor intensity of the staff and reducing the occurrence of occupational diseases.

[0031] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0032] Example 1

[0033] Reference Figures 1 to 6 A ship maintenance tool comprises a dock 4, a dock command room 1 is arranged at the top of the dock 4 near the edge, a booster water pump and a suction integrated hydraulic pump are arranged in the dock command room 1, a dock gate 2 is rotatably connected to the opening of the dock 4, a plurality of water inlet valves 22 are evenly arranged on the dock gate 2, seawater enters the dock 4 through the water inlet valves 22, and an ultrasonic generator 21 is installed on the top of the dock gate 2, a staff starts the power supply of the dock gate 2 in the dock command room 1, lowers the dock gate 2, thereby allowing the ship to enter the dock 4, and the ultrasonic generator 21 on the dock gate 2 can be energized through the dock command room 1, so that the ultrasonic generator 21 generates high-frequency ultrasonic waves. When the ship enters the dock 4 at a uniform speed, it will pass over the ultrasonic generator 21. At this time, the ultrasonic generator 21 is in a powered-on state. When the bottom part of the ship above the ultrasonic generator 21 suddenly enters the high-frequency ultrasonic field, it will be affected by the acoustic thermal effect and the bottom part of the ship at this position will heat up, eventually causing the bottom part of the ship above the ultrasonic generator 21 to generate high temperature itself. Organisms such as barnacles, mussels, oysters and other organisms attached to the bottom part generating high temperature will die under the sudden high temperature and the biological protein mucus that can be adsorbed on the bottom of the ship will be denatured, thereby greatly reducing the adsorption force and peeling off under the joint impact of seawater vibration caused by ultrasonic waves and cavitation bubbles.

[0034] Reference Figures 1 to 6The dock 4 is provided with a ship repair mechanism 3 for stably lifting a large ship entering the working tank 311, so as to facilitate the repair work on the bottom of the large ship. The ship repair mechanism 3 includes a base 31, a working tank 311 is provided at the top of the base 31, and a plurality of bases 34 are slidably connected to the working tank 311. The parts of the plurality of bases 34 located inside the working tank 311 are all provided with driving components for driving the bases 34 to move. The plurality of bases 34 are all provided with lifting components 35, and the plurality of bases 34 are provided with a plurality of lifting components 35. The bases 34 are connected to a plurality of lifting assemblies through lifting assemblies 35. The lifting assemblies are used to lift ships of different types. The lifting assemblies 35 are used to lift the lifting assemblies. The lifting assemblies include two sets of tooling frames 36. The two sets of tooling frames 36 are installed at the output end of the lifting assemblies 35. The tops of the two sets of tooling frames 36 are arc-shaped and the tops of the two sets of tooling frames 36 are jointly provided with supporting components 37, which are used to ensure the stability of the ship when lifting the ship and prevent the ship from losing stability and tipping over. The supporting components 37 includes a rubber bag 1 371 and a rubber bag 2 372, which are respectively mounted on the top of two sets of tooling frames 36. Since there are multiple sets of lifting components, there are multiple sets of tooling frames 36. The multiple sets of tooling frames 36 are commonly provided with oil supply components for supplying hydraulic oil to the rubber bags 1 371 and the rubber bags 2 372 on each set of tooling frames 36. The oil supply components include multiple sets of hydraulic pipes 39, which are respectively mounted between each set of tooling frames 36, and each set of tooling frames 36 is respectively connected to the hydraulic pipes 39. They are interconnected through hydraulic pipes 39, and one end of multiple groups of hydraulic pipes 39 connected to each group of tooling frames 36 passes through the outer wall of the tooling frame 36, and are respectively connected to the inside of rubber bag 1 371 and rubber bag 2 372. One end of a group of hydraulic pipes 39 close to the dock command room 1 away from the tooling frame 36 is connected to the output end of the integrated suction hydraulic pump in the dock command room 1. The integrated suction hydraulic pump in the dock command room 1 provides hydraulic oil to the rubber bag 1 371 and the rubber bag 2 372 on each group of tooling frames 36 through the hydraulic pipes 39.

[0035] Reference Figures 2 to 4 The driving assembly includes multiple sets of power wheels 341, which are rotatably connected to both sides of the base 34 respectively. Guide grooves 312 are symmetrically opened on both sides of the working groove 311. The multiple sets of power wheels 341 are respectively located in the two sets of guide grooves 312, and the outer side walls of the multiple sets of power wheels 341 are respectively in contact with the top walls and top walls of the two sets of guide grooves 312. Before the ship enters the dock 4, the staff in the dock command room 1 controls the power wheels 341 of each base 34 to move back and forth in the guide groove 312 in advance according to the ship size data sent by the ship, to ensure that each tooling rack 36 is evenly distributed under the ship. When the ship completely enters the dock 4, the ultrasonic generator 21 is powered off, and then the dock gate 2 is pulled up through the dock command room 1, thereby isolating and sealing the dock 4 from the sea.

[0036] reference Figures 2 to 6The lifting assembly 35 includes multiple groups of oil cylinders 351, which are evenly installed inside the base 34, and the output ends of the multiple groups of oil cylinders 351 all penetrate the inner top wall of the base 34 and are fixedly connected to the bottom ends of the two groups of tooling frames 36 respectively. The multiple groups of oil cylinders 351 are made of stainless steel. The oil cylinders 351 are made of stainless steel to have excellent corrosion resistance, which prolongs the service life of the oil cylinders 351. Stainless steel has the characteristics of high strength and rigidity, which makes it difficult for the oil cylinders 351 to deform or be damaged. After the dock gate 2 is pulled up, the tooling frames 36 that have been in place are lifted up by the oil cylinders 351 in the lifting assembly 35. During the process, 50% of the oil is filled into the rubber bag 1 371 and the rubber bag 2 372 in the support component 37 through the suction integrated hydraulic pump. The lifting assembly 35 is continuously raised until the supporting component 37 contacts the bottom of the ship and is squeezed. The supporting component 37 is covered to adapt to the slight changes in the size and structure of the bottom of the ship and increase the force-bearing area. At this time, the rubber bag 1 371 in each group of supporting components 37 stops supplying oil and maintains 50% of the oil filling amount. With the cooperation of buoyancy, the rubber bag 2 372 continues to take in oil and detects the internal pressure of the rubber bag 2 372 and then feeds it back to the dock command room 1 to avoid the rubber bag 2 372 from malfunctioning or even rupturing due to the rapid change in internal pressure. The oil supply rate of each rubber bag 2 372 is changed by the change in the internal pressure of the rubber bag 2 372. The rubber bag 2 372 with a slower pressure change has a higher oil supply rate. When the pressure of all rubber bags 2 372 is consistent, the dock command room 1 The control room 1 determines that the center of gravity of the ship has been balanced, and the dock 4 pumps out the water inside at a uniform speed. As the water level drops, each rubber bag 2 372 feeds back the pressure change to the dock control room 1, and fine-tunes the oil volume in the rubber bag 2 372 according to the pressure to ensure that the pressure of each rubber bag 2 372 is always the same. During this period, if a rubber bag 2 372 fails or ruptures, the rubber bag 1 371 that is paired with it and maintains 50% of the oil volume will be immediately filled with oil to replace the same group of failed rubber bag 2 372 to prevent the ship from becoming unstable and tipping over, until the water is completely pumped out. When the water is completely pumped out, the lifting assembly 35 descends to the origin, so that the bottom of the tooling frame 36 contacts the base 34 to reduce the load of the lifting assembly 35, and the maintenance personnel enter the site to check and confirm the support components 37. After it is in good condition, the rubber bag 1 371 with 50% oil volume will be drained and collected into the tooling rack 36, and the maintenance personnel will start the maintenance work on the bottom of the ship. When the maintenance is completed and the exposed parts of the bottom of the ship are cleaned, sandblasted and painted, the rubber bags 1 371 collected in the tooling rack 36 will be filled with oil to the pressure of the rubber bags 2 372 in the same group, and then the rubber bags 2 372 will be slowly drained. At this time, the oil volume will be fine-tuned according to the different pressures inside each rubber bag 1 371 until the pressure is the same. During this period, if the rubber bag 1 371 fails or ruptures, the rubber bags 2 372 in the same group that are draining oil will immediately switch from the original draining to supplying oil until the original state is reached to ensure the safety of the on-site personnel and prevent accidents. When there is no failure in the rubber bag 1 371 and the pressures are adjusted to be consistent,After the rubber bag 2 372 in the same group releases oil to 50% of the oil volume, it switches to rapid oil release and is quickly stored in the tooling rack 36. The maintenance personnel carry out maintenance, sandblasting and painting on the previously pressed area to ensure the integrity of the maintenance work.

[0037] Reference Figures 2 to 5A cleaning mechanism 32 is provided at the bottom of the working tank 311 for scraping and washing the bottom wall and side wall of the working tank 311. The cleaning mechanism 32 includes a scraper 321. The bottom end of the scraper 321 is rotatably connected to a plurality of power wheels 323, and the scraper 321 contacts the bottom wall of the working tank 311 through the plurality of power wheels 323. Guide wheels 322 are installed on both sides of the scraper 321. The outer wall of the guide wheel 322 contacts the side wall of the working tank 311. The guide wheel 322 is used to limit and guide the scraper 321. A washing component is provided at the top of the scraper 321 for washing the bottom wall and side wall of the working tank 311 and cooperating with the ultrasonic generator 21 to spray off dirt such as bottom organisms that have lost adhesion to the bottom of the ship. The washing component includes two sets of high-pressure water gun machines The manipulator 33 and two sets of automatic wire reels 38, the two sets of high-pressure water gun manipulators 33 and the two sets of automatic wire reels 38 are symmetrically arranged at the top of the scraper 321, and the two sets of automatic wire reels 38 are wound with water inlet pipes 381. The water inlet pipes 381 are automatically retracted and released by controlling the automatic wire reels 38. One end of the two sets of water inlet pipes 381 is respectively connected to the two sets of high-pressure water gun manipulators 33, and the other ends of the two sets of water inlet pipes 381 pass through the outer wall of the base 31 and are connected to the output end of the booster pump in the dock command room 1. When the ship enters the dock 4 at a uniform speed and the ultrasonic generator 21 is in the energized state, the control personnel in the dock command room 1 turn on the booster pump to provide high-pressure water to the two high-pressure water gun manipulators 33 through the water inlet pipes 381. At this time, the ship maintenance mechanism 3. The two high-pressure water gun manipulators 33 on the cleaning mechanism 32 at the head end are unfolded to point the muzzles of the high-pressure water guns toward the bottom of the ship and spray high-pressure water. As the ship moves forward, the remaining unpeeled-off bottom organisms will fall off from the bottom of the ship one by one under the action of the high-pressure water guns, thereby completing the cleaning of the attached organisms on the bottom of the ship. After the ship enters the dock 4 and all the ship maintenance work is completed, all personnel leave the working tank 311 on the base 31, and the high-pressure water gun manipulator 33 flushes the bottom wall and side walls of the working tank 311 to peel off the dirt and some of the organisms re-attached to the working tank 311 from the working tank 311. At the same time, the dock command room 1 controls the power wheel 323 to move, thereby driving the scraper 321 to start moving, and the guide wheel 322 on the side wall Roll to guide the scraper 321, and the automatic reel 38 automatically retracts and releases the water inlet pipe 381 to ensure the supply of high-pressure water during movement. On the way forward, the scraper 321 scrapes off the dirt on the bottom wall and side walls of the working tank 311 and pushes it towards the dock command room 1. Finally, all the dirt is pushed off the base 31, and then the cleaning mechanism 32 is reset. The personnel immediately carry out cleaning and transportation processing work, which eliminates the step of personnel cleaning the bottom of the ship, improves safety, reduces the labor intensity of personnel, and reduces the occurrence of occupational diseases. After all the work is completed, water is put into the dock 4 through the water inlet valve 22. When the water levels inside and outside the dock gate 2 are consistent, the ship floats, the components in the ship maintenance mechanism 3 are reset, the dock gate 2 is opened, and the ship sails out of the dock 4.

[0038] The present invention is applied to the bottom maintenance of large ships. At present, the maintenance dock 4 uses simple tools such as wooden blocks to raise the ship. After the ship enters the dock, professional divers need to dive into the dim water to confirm and adjust the position of the tools. The work of divers is extremely dangerous and the accuracy of the tool position is not guaranteed. The ship is prone to accidents such as capsizing during maintenance, and there is no safety guarantee for on-site personnel, ships, docks 4 and their facilities.

[0039] In this design, a large ship sails to the dock 4 under the tow of a tugboat, and the staff starts the power supply of the dock gate 2 in the dock command room 1. The dock gate 2 is lowered to allow the ship to enter the dock 4. At the same time, the ultrasonic generator 21 is powered to generate high-frequency ultrasonic waves. The staff in the dock command room 1 controls the power wheels 341 of each base 34 to move back and forth in the guide groove 312 in advance according to the ship size data sent by the ship, ensuring that each tooling rack 36 is evenly distributed under the ship. The ship enters the dock 4 at a uniform speed and passes over the ultrasonic generator 21 during the process. When the bottom part of the ship above the ultrasonic generator 21 suddenly enters the high-frequency ultrasonic field, it is affected by the acoustic thermal effect, and the bottom part of the ship at this position will heat up, and finally the bottom part of the ship above the ultrasonic generator 21 itself generates high temperature, which is attached to the ship generating high temperature. Organisms at the bottom, such as barnacles, mussels, oysters, etc., die under the sudden high temperature and the biological protein mucus that can be adsorbed on the bottom of the ship is denatured, thereby greatly reducing the adsorption force, and they are peeled off under the joint impact of seawater vibration caused by ultrasound and cavitation bubbles. At the same time, the control personnel in the dock command room 1 turn on the booster pump to provide high-pressure water to the two high-pressure water gun manipulators 33 through the water inlet pipe 381. At this time, the two high-pressure water gun manipulators 33 located at the opening of the dock 4 are unfolded to point the muzzles of the high-pressure water guns toward the bottom of the ship and spray high-pressure water. As the ship moves forward, the remaining unpeeled bottom organisms will fall off from the bottom of the ship one by one under the action of the high-pressure water guns, and finally the ship will completely enter the dock 4, then the ultrasonic generator 21 will be powered off, and then the dock gate 2 will be pulled up through the dock command room 1, thereby isolating and sealing the dock 4 from the sea.

[0040] Two tooling racks 36 are installed together on the same base 34 in a group. The suction integrated hydraulic pump in the dock command room 1 provides hydraulic oil to the rubber bag 1 371 and the rubber bag 2 372 on each group of tooling racks 36 through the hydraulic pipe 39. The tooling racks 36 that have been in place are lifted up by the oil cylinder 351 in the lifting assembly 35. On the way, the rubber bag 1 371 and the rubber bag 2 372 in the supporting component 37 are filled with 50% hydraulic oil and swelled. The lifting assembly 35 continues to rise until the supporting component 37 contacts the bottom of the ship and is squeezed. The supporting component 37 is covered to adapt to the slight changes in the size and structure of the bottom of the ship and increase the force-bearing area. At this time, the rubber bag 1 371 in each group of the supporting component 37 stops supplying oil and maintains 50% of the oil filling amount. With the cooperation of buoyancy, the rubber bag 2 372 continues to take in oil and detects the internal pressure of the rubber bag 2 372 and then feeds it back to the dock command. Chamber 1, to prevent the rubber bag 2 372 from malfunctioning or even rupturing due to a sharp change in internal pressure, the oil supply rate of each rubber bag 2 372 is changed by the change in internal pressure of the rubber bag 2 372, and the rubber bag 2 372 with a slower pressure change has a higher oil supply rate. When the pressures of all rubber bags 2 372 are consistent, the dock command room 1 determines that the center of gravity of the ship has been balanced, and the dock 4 pumps out the internal water at a uniform speed. As the water level drops, each rubber bag 2 372 feeds back the change in pressure to the dock command room 1, and fine-tunes the amount of oil in the rubber bag 2 372 according to the pressure to ensure that the pressure of each rubber bag 2 372 is always the same. During this period, if a rubber bag 2 372 fails or ruptures, the rubber bag 1 371 that maintains 50% of the oil volume with it will be immediately and quickly filled with oil to replace the same group of faulty rubber bag 2 372, to prevent the ship from becoming unstable and tipping over, until the water is completely pumped out.

[0041] When the water is completely pumped out, the lifting assembly 35 descends to the origin, so that the bottom of the tooling frame 36 contacts the base 34 to reduce the load of the lifting assembly 35. After the maintenance personnel enter the site to check and confirm that the supporting component 37 is intact, the rubber bag 1 371 holding 50% of the oil is retracted into the tooling frame 36, and the maintenance personnel begin to inspect the bottom of the ship. When the inspection is completed and the exposed parts of the bottom of the ship are cleaned, sandblasted and painted, since the rubber bag 2 372 supports the ship, the part of the bottom of the ship supported by the rubber bag 2 372 is blocked and not processed. Based on this, after the rubber bags 1 371 collected in the tooling frame 36 are filled with oil to the pressure of the same group of rubber bags 2 372, the same group of rubber bags 2 372 slowly release oil. At this time, the oil volume is fine-tuned according to the different pressures inside each rubber bag 1 371 until the pressure is the same. During this period, if the rubber bag 1 371 fails or ruptures, the rubber bag 2 372 in the same group that is releasing oil will immediately switch to supplying oil to the original pressure to ensure the safety of on-site personnel and prevent accidents.

[0042] When there is no failure of rubber bag 1 371 and the pressures are all adjusted to be consistent, rubber bag 2 372 of the same group that is draining oil drains oil to 50% of the oil volume and then switches to rapid draining and is quickly collected into the tooling rack 36. The maintenance personnel perform maintenance, sandblasting, painting and other work on the previously pressed area to ensure the integrity of the maintenance work. When the maintenance work is completed, the personnel leave the working tank 311 on the base 31, and the high-pressure water gun manipulator 33 rinses the bottom wall and side walls of the working tank 311 to peel off the dirt and some of the organisms that have re-attached to the working tank 311 from the working tank 311. At the same time, the scraper 321 starts to move under the action of the power wheel 1 323, and the guide wheel 322 rolls on the side wall to guide the scraper 321, which is then automatically reeled in by the automatic wire reel 38. The automatic retraction and extension of the water inlet pipe 381 ensures the supply of high-pressure water during movement. On the way forward, the scraper 321 scrapes off the dirt on the bottom wall and side walls of the working tank 311 and pushes it towards the dock command room 1. Finally, all the dirt is pushed off the base 31. Then the cleaning mechanism 32 is reset, and the personnel immediately carry out cleaning and transportation processing work, which eliminates the step of personnel cleaning the bottom of the ship, improves safety, reduces the labor intensity of personnel, and reduces the occurrence of occupational diseases. After all the work is completed, the water inlet valve 22 releases water into the dock 4. When the water levels inside and outside the dock gate 2 are consistent, the ship floats, the components in the ship maintenance mechanism 3 are reset, the dock gate 2 is opened, the ship sails out of the dock 4, and the subsequent ships to be inspected enter the dock 4 to repeat the previous work.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
