Technical Field
[0001] This utility model relates to the field of ship cleaning technology, and in particular to a ship cleaning submersible. Background Technology
[0002] Ships are important means of maritime transportation. As ships sail at sea for long periods of time, they accumulate fouling, mainly including rust, shellfish, barnacles, etc., which affect the service life and speed of ships.
[0003] In the prior art, Chinese Patent Publication No. CN216546629U discloses an underwater robot for cleaning ship walls, including a hull, a sealed chamber installed in the middle of the hull, tracked devices on both sides of the bottom of the sealed chamber, four buoyancy propellers at the four corners of the bottom of the sealed chamber, and forward and backward propellers on both sides of the end walls of the sealed chamber. The buoyancy propellers are used to control the hull's surfacing and diving movements, and the forward and backward propellers are used to control the hull's forward and backward movements. Four grinding discs are located at the rear of the bottom of the hull, and all four grinding discs rotate inward about the center line of the bottom of the hull. An enzyme-dissolving launching device is located at the top of the hull. This utility model adopts an underwater cleaning method combining grinding discs and enzyme-dissolving projectiles. Two pairs of grinding discs are located at the rear of the bottom of the underwater robot. During rotation, these discs can both protect the ship's hull coating and remove attached organisms. Simultaneously, the arrangement of the enzyme-dissolving launching device can more effectively remove stubborn organisms from the ship's walls.
[0004] However, in actual use, the new invention cleans by rotating the grinding disc. After long-term use, the surface of the grinding disc is worn by friction, which affects the cleaning effect and makes it inconvenient to replace. Due to the high flatness of the grinding disc, there are certain limitations in cleaning. It is difficult to clean dirt in crevices. Therefore, improvements are needed. Utility Model Content
[0005] The purpose of this invention is to provide a marine cleaning submersible device that has a wider range of applications during cleaning and facilitates the replacement of hard bristles.

[0007] By adopting the above technical solution, during ship cleaning, the traveling wheels, equipped with magnets, can adhere to the hull surface for movement. During movement, a cylinder drives a telescopic rod to extend, causing the cleaning disc to descend and contact the hull surface with the hard bristles. When the waterproof motor starts, the first and second flanges rotate, driving the cleaning disc to rotate as well. The mechanical force of the hard bristles removes surface dirt. The bristles can reach into crevices for cleaning without scratching the hull surface. The height of the hard bristles can be adjusted to regulate the contact force with the hull, allowing for adjustments to the cleaning intensity based on the stubbornness of the stains. When the hard bristles wear down, the first and second flanges can be disassembled and the cleaning disc replaced. This design offers a wider range of applications and facilitates the replacement of the hard bristles.
[0008] A further feature of this invention is that both the body and the waterproof box have perforations inside, and the inner wall of the perforation is fixedly connected with an elastic sealing sleeve.
[0009] By adopting the above technical solution, the telescopic rod slides inside the elastic sealing sleeve when it extends or retracts, and the elastic sealing sleeve can prevent water from entering and causing perforation.
[0010] A further feature of this invention is that a sliding rod is fixedly connected to the top of the first flange, and a support sleeve is slidably connected to the outer surface of the sliding rod.
[0011] By adopting the above technical solution, the slide bar slides inside the support sleeve, providing effective support during movement.
[0012] A further feature of this invention is that the first flange is internally threaded with bolts, and the number of bolts is four.
[0013] By adopting the above technical solution, the two flanges are fixed with bolts, and the bolts are rust-proof bolts.
[0014] A further feature of this invention is that a differential propeller is fixedly connected to one end of the fuselage, and the number of differential propellers is two.
[0015] By adopting the above technical solution, two differential propellers are used for the equipment to move forward and backward in the water and in front of the water.
[0016] A further feature of this invention is that a cleaning box is fixedly connected to the top of the machine body, and the cleaning box contains cleaning fluid.
[0017] By adopting the above technical solution, the cleaning box is filled with cleaning solution that dissolves stains.
[0018] A further feature of this invention is that a water pump is fixedly connected inside the cleaning box, and a water delivery pipe is fixedly connected to the output end of the water pump.
[0019] By adopting the above technical solution, the water pump draws in the cleaning fluid, which is then transported through the water pipe.
[0020] A further feature of this invention is that a spray pipe is fixedly connected to one end of the water supply pipe, and a bracket is fixedly connected to the top of the spray pipe.
[0021] By adopting the above technical solution, cleaning fluid is introduced into the spray pipe, and the surface of the hull is sprayed with cleaning fluid before the hard brush bristles are cleaned.
[0022] A further feature of this invention is that a high-pressure nozzle is fixedly connected to the bottom of the spray pipe, and the number of the high-pressure nozzles is six.
[0023] By adopting the above technical solution, the high-pressure nozzle sprays out cleaning liquid with water pressure, which impacts the stains and makes them easier to dissolve, reducing the cleaning difficulty of hard brush bristles.
[0024] A further feature of this invention is that a magnetic layer is fixedly connected to the outer surface of the walking wheel, and the outer surface of the magnetic layer is coated with a wear-resistant coating.
[0025] By adopting the above technical solution, the magnetic attraction generated by the magnetic layer facilitates the adhesion of the wheels to the hull, and the wear-resistant coating prevents the magnetic layer from being worn.
[0026] The beneficial effects of this utility model are:
[0027] 1. This utility model, through the coordinated arrangement of the body, wheels, waterproof box, cylinder, telescopic rod, waterproof motor, first flange, second flange, cleaning disc, and hard bristles, enables the device to move by magnetically adhering to the hull surface during ship cleaning. During movement, the cylinder drives the telescopic rod to extend, causing the cleaning disc to descend and contact the hard bristles with the hull surface. When the waterproof motor starts, the first and second flanges rotate, driving the cleaning disc to rotate. The mechanical force of the hard bristles removes surface dirt, reaching into crevices for cleaning without scratching the hull surface. The height of the hard bristles can be adjusted to regulate the contact force with the hull, allowing for adjustment of cleaning intensity based on the stubbornness of the stains. When the hard bristles wear down, the first and second flanges can be disassembled for cleaning disc replacement. This design offers a wider range of applications and facilitates the replacement of hard bristles.

This utility model, through the coordinated arrangement of perforations, elastic sealing sleeves, sliding rods, support sleeves, bolts, differential propellers, cleaning boxes, water pumps, water supply pipes, spray pipes, brackets, high-pressure nozzles, magnetic layers, and wear-resistant coatings, enables the telescopic rod to slide inside the elastic sealing sleeve during use. The elastic sealing sleeve prevents water from entering the perforations. The sliding rod slides inside the support sleeve, providing effective support during movement. Two flanges are fixed with bolts, which are rust-proof bolts. The water pump draws cleaning fluid, which is then transported through the water supply pipe. Cleaning fluid is introduced into the spray pipe. Before cleaning with hard brush bristles, the hull surface is sprayed with cleaning fluid. The high-pressure nozzle sprays cleaning fluid with water pressure, impacting stains and facilitating their dissolution, reducing the cleaning difficulty of the hard brush bristles. The magnetic layer generates suction, allowing the wheels to adhere to the hull. The wear-resistant coating prevents the magnetic layer from being worn. Attached Figure Description

[0036] A ship-cleaning submersible includes the following embodiments:
[0037] Example 1:
[0038] Reference Figure 1-4 The bottom of the machine body 1 is provided with a walking wheel 2, the top of the machine body 1 is fixedly connected with a waterproof box 3, the inner wall of the waterproof box 3 is fixedly connected with a cylinder 4, the output end of the cylinder 4 is fixedly connected with a telescopic rod 5, the bottom of the telescopic rod 5 is fixedly connected with a waterproof motor 6, the output end of the waterproof motor 6 is fixedly connected with a first flange 7, the bottom of the first flange 7 is provided with a second flange 8, the bottom of the second flange 8 is fixedly connected with a cleaning disc 9, and the bottom of the cleaning disc 9 is fixedly connected with hard bristles 10.
[0039] Specifically, during ship cleaning, the traveling wheels 2, equipped with magnets, can adhere to the ship's surface for movement. During movement, the cylinder 4 drives the telescopic rod 5 to extend, thereby lowering the cleaning disc 9 and bringing the hard brush bristles 10 into contact with the ship's surface. When the waterproof motor 6 is started, the first flange 7 and the second flange 8 rotate, driving the cleaning disc 9 to rotate. The mechanical force of the hard brush bristles 10 removes dirt from the surface. When encountering crevices, the bristles can reach into the crevices to clean without scratching the ship's surface. The contact force with the ship can be adjusted by adjusting the height of the hard brush bristles 10, and the cleaning intensity can be adjusted according to the stubbornness of the stains. When the hard brush bristles 10 become worn, the first flange 7 and the second flange 8 can be disassembled and separated to replace the cleaning disc 9. This design allows for a wider range of applications during cleaning and facilitates the replacement of the hard brush bristles 10.
[0040] Example 2:

A magnetic layer 23 is fixedly connected to the outer surface of the walking wheel 2. The outer surface of the magnetic layer 23 is coated with a wear-resistant coating 24.
[0042] Specifically, the telescopic rod 5 slides inside the elastic sealing sleeve 12 when it extends or retracts, and the elastic sealing sleeve 12 can prevent water from entering the perforation 11. The sliding rod 13 slides inside the support sleeve 14 and provides effective support when moving. The bolts 15 fix the two flanges. The bolts 15 are rust-proof bolts.

The cleaning tank 17 is filled with cleaning liquid that dissolves stains. The water pump 18 draws the cleaning liquid and delivers it through the water pipe 19. The cleaning liquid is introduced into the spray pipe 20. The surface of the hull is sprayed with cleaning liquid before the hard brush 10 is cleaned. The high-pressure nozzle 22 sprays the cleaning liquid with water pressure, which impacts the stains and makes them easier to dissolve, reducing the cleaning difficulty of the hard brush 10. The magnetic layer 23 generates attraction to facilitate the walking wheel 2 to adhere to the hull. The wear-resistant coating 24 prevents the magnetic layer 23 from being worn.
[0043] In this invention, during ship cleaning, the traveling wheels 2, equipped with magnets, can adhere to the ship's surface for movement. During movement, the cylinder 4 drives the telescopic rod 5 to extend, thereby lowering the cleaning disc 9 and bringing the stiff brush bristles 10 into contact with the ship's surface. When the waterproof motor 6 starts, the first flange 7 and the second flange 8 rotate, driving the cleaning disc 9 to rotate. The mechanical force of the stiff brush bristles 10 removes surface dirt. The bristles can reach into crevices for cleaning without scratching the ship's surface. The height of the stiff brush bristles 10 can be adjusted to regulate the contact force with the ship, allowing for adjustments to the cleaning intensity based on the stubbornness of the stains. When the stiff brush bristles 10 become worn, the first flange 7 and the second flange 8 can be disassembled for further cleaning of the cleaning disc 9. The hard brush 10 is easy to replace, and the telescopic rod 5 slides inside the elastic sealing sleeve 12 when it extends or retracts. The elastic sealing sleeve 12 can prevent water from entering the perforation 11. The sliding rod 13 slides inside the support sleeve 14, providing effective support when moving. The bolt 15 fixes the two flanges. The bolt 15 is a rust-proof bolt. The water pump 18 draws the cleaning liquid and delivers it through the water pipe 19. The cleaning liquid is introduced into the spray pipe 20. Before cleaning, the surface of the hull is sprayed with cleaning liquid. The high-pressure nozzle 22 sprays the cleaning liquid with water pressure, which impacts the stains and makes them easier to dissolve, reducing the cleaning difficulty of the hard brush 10. The magnetic layer 23 generates a suction force that makes it easy for the traveling wheel 2 to adhere to the hull. The wear-resistant coating 24 prevents the magnetic layer 23 from being worn.
