Description

Technical Field

[0001] The utility model belongs to the technical field of ship cleaning, in particular to a novel floating cleaning device. Background Art

[0002] As the main means of transportation for cargo transportation, it is increasingly important to clean, rust and paint the bottom, sides, top, bottom slope, side ribs and outer wall of the ship. Ships sail in seawater for a long time, and there are large areas of erosion and corrosion caused by seawater and sea breeze, rust and paint loss, and the growth of marine organisms such as oysters on the surface, making it difficult to remove marine microorganisms, algae and shells attached to the surface of the hull. As the working time of ships and cargo ships increases, there will be more and more marine microorganisms, algae and shells on the surface of the hull, which not only affects the beauty of the cargo hold of the ship, but also reduces the speed of the ship, increases fuel consumption, and increases the transportation cost of the ship. Therefore, the cleaning of marine microorganisms on the wall of the ship is very important, which can greatly improve the transportation cost and service life of the ship.

[0003] At present, the main methods of ship cleaning are manual operation and robots. Generally, most people use handheld high-pressure water guns or carry cleaning brushes to clean the walls of ships. Operators dive into deep water with a certain lack of oxygen and high pressure, attach to the wall of the ship, and manually clean the marine life on the wall of the ship from top to bottom. There are problems such as low cleaning efficiency, low cleaning effect, long cleaning cycle, high risk factor, low safety, long time consumption, high labor intensity, and high labor cost. Some wall-climbing robots with fixed cleaning structures are used, but they cannot automatically adapt to the wall of the ship according to the growth of marine organisms, cannot adjust the cleaning target distance and cleaning angle, and cannot set multiple floating cleaning disc mechanisms on the underwater cleaning robot of the ship, resulting in a small cleaning area, poor cleaning effect, and low cleaning efficiency.

[0004] The patent "A Ship Underwater Cleaning Robot with Adjustable Center of Gravity" (patent number: CN 116691947A) discloses a ship underwater cleaning robot with adjustable center of gravity, including a cleaning mechanism, a propulsion mechanism, a center of gravity adjustment mechanism, a sensor system, and a main frame module. The floating cleaning mechanism can keep the cavitation jet rotating tool holder and the wall to be cleaned at the optimal distance. The propulsion mechanism can realize the movement of each degree of freedom of the robot and the preset fixed-course and fixed-depth cleaning functions while using fewer propellers. At the same time, a simple directional wheel structure is used to solve the problem of the robot shaking due to the influence of the jet during the cleaning operation. The center of gravity adjustment mechanism is used to adjust the center of gravity of the robot so that the center of gravity of the robot is always kept directly below the center of buoyancy, thereby maintaining the stability of the robot. However, the cleaning area is small, the cleaning effect is poor, and the cleaning efficiency is low.

[0005] The patent "An adsorption-type underwater cleaning robot" (patent number: CN 112027015 A) discloses an adsorption-type underwater cleaning robot, which adopts cavitation jet cleaning method. The robot frame is equipped with a propeller propeller, a cavitation jet nozzle, a sprocket support frame, a camera, a searchlight, and a buoyancy material. The sprocket support frame is equipped with a stepper motor, a driving sprocket, a driven sprocket, a spring connection seat, a chain, and a crawler. The permanent magnet installed on the crawler generates magnetic force to adsorb on the surface of the ship. However, the cleaning area is small, the cleaning effect is poor, and the cleaning efficiency is low.

[0006] The patent "An Underwater Cleaning Robot" (patent number: CN 101695832 A) discloses an underwater cleaning robot, including a main body and a walking part arranged on the main body, the walking part includes a left wheel group and a right wheel group that can rotate independently, the left wheel group includes a left front wheel and a left rear wheel, the right wheel group includes a right rear wheel and a right front wheel, and the robot is provided with a transmission part of the left wheel group and a transmission part of the right wheel group that are independent of each other. However, the cleaning area is small, the cleaning effect is poor, and the cleaning efficiency is low.

[0007] The three cleaning devices with similar structures listed above have problems such as being unable to adapt to the wall of the ship, unable to transition between concave and convex walls with a certain inclination angle, unable to transition between multiple walls, unable to adjust the cleaning target distance and cleaning angle, and unable to set multiple floating cleaning disc mechanisms on the ship's underwater cleaning robot due to many reasons, resulting in poor obstacle crossing ability, weak transition ability, low wall adaptability, inflexible floating of the cleaning disc, small cleaning area, poor cleaning effect, and low cleaning efficiency.

[0008] Therefore, it has become an urgent problem to design a new floating cleaning device that can adapt to the ship wall, transition between concave and convex wall surfaces, transition between multiple wall surfaces, adjust the cleaning target distance and cleaning angle, set multiple floating cleaning disc mechanisms on the ship underwater cleaning robot, have a large cleaning area, good cleaning effect, and high cleaning efficiency.
