Description

Technical Field

[0001] The invention relates to the technical field of ship rust removal, in particular to a high-pressure water spraying rust removal device for ship outer plates. Background Art

[0002] Ships are vehicles that can sail or anchor in waters for transportation or operations. Modern ships are usually made of metal materials such as steel. They are in contact with water all year round and are prone to rust, so they need maintenance and rust removal. As a type of physical rust removal, high-pressure water jet rust removal technology has significant advantages over chemical rust removal and other physical rust removal methods. First of all, this technology uses the water jet generated by an ultra-high pressure water pump to impact the surface of the ship plate. When the impact energy of the water flow is greater than the adhesion of the rust to the steel substrate, the rust layer can be effectively removed. This method not only avoids the environmental pollution caused by chemical rust removal, but also reduces the secondary corrosion that may be caused to the metal surface. Compared with shot peening and shot blasting rust removal, high-pressure water jet rust removal does not produce dust pollution, nor does it cause the problem of increased roughness or reduced hardness of the metal surface. From an environmental protection perspective, high-pressure water jet rust removal technology also performs well. The water used in the rust removal process can be recycled and reused, and the wastewater can meet the emission standards after treatment, greatly reducing pollution to the environment. In addition, by using advanced technologies such as vacuum system adsorption slag removal and wall climbing robot operation, the rust removal efficiency is further improved and the cost is reduced. The environmental protection characteristics of this technology meet the requirements of green manufacturing and environmental protection, and are an important support for achieving a sustainable development strategy. In terms of improving operating efficiency, high-pressure water jet rust removal technology also shows obvious advantages. Compared with traditional manual rust removal and chemical rust removal, this technology can quickly and extensively remove rust, greatly shortening the time for ship repair and maintenance. At the same time, due to its non-contact characteristics, it avoids damage to the substrate and ensures the quality of rust removal. This high efficiency and high quality make high-pressure water jet rust removal one of the rust removal methods that shipyards and shipowners prioritize.

[0003] In summary, high-pressure water jet rust removal technology has shown great application value in the field of ship outer plate rust removal with its advantages of no damage, no dust pollution, high rust removal efficiency and no environmental pollution. It not only improves the efficiency and quality of rust removal operations, but also meets environmental protection requirements. It is an important technical support for promoting the green and high-quality development of the ship repair industry. With the continuous advancement of science and technology and the improvement of environmental protection requirements, high-pressure water jet rust removal technology will be more widely used and developed. For thick rust that is firmly attached, a higher spraying pressure is required. This type of rust generally exists in areas where the hull has been immersed in seawater for a long time, or in parts that are exposed due to peeling of protective coatings. For this type of rust, it is recommended to use a water flow with a pressure of 2500 to 3000 Bar or higher for spraying. Such a high-pressure water flow can effectively destroy the structure of the thick rust layer and peel it off the metal surface. For a weaker rust layer or a newer rust, a lower spraying pressure can be used, usually between 1500 and 2000 Bar. This pressure is sufficient to remove surface rust, while reducing the impact on the ship's outer plate and protecting the integrity of the primer and substrate. This method is suitable for well-maintained ships or areas that have recently experienced slight rust. However, traditional high-pressure water spraying devices use a constant spraying pressure and cannot be intelligently adjusted according to the specific situation of the rust. There may be situations where the spraying pressure is too high, causing damage to the substrate, or the spraying pressure is too low to completely remove the thick rust that is firmly attached. Therefore, we propose a high-pressure water spraying rust removal device for ship outer plates to solve this problem. Summary of the invention

[0021] The beneficial effects of the present invention are:

[0022] 1. In the present invention, the high-pressure water spray rust removal device for ship outer plate is moved to make the water spray rust removal device close to the ship outer plate, and make the rotating wheel abut against the outer side of the ship outer plate, and then the knob is rotated to drive the horizontal axis to rotate, and the horizontal axis drives the two vertical screws to rotate synchronously through the meshing of two active bevel gears and corresponding driven bevel gears, and the vertical screw drives the lifting frame to move upward through the thread transmission with the lifting frame, and the lifting frame drives the universal wheel to move upward, so that the universal wheel is retracted and separated from the ground and the supporting legs are in contact with the ground, so as to ensure stable placement;

[0023] 2. In the present invention, the high-pressure water spraying rust removal device for ship outer plates sends a control signal to the controller remotely, and the controller controls the electric control switch to close, so that the driving motor and the high-pressure water pump are energized. After the high-pressure water pump is started, the water in the water tank is extracted through the water inlet pipe, and the high-pressure water is introduced into the spray barrel through the hose, and sprayed from multiple high-pressure nozzles, so as to wash and remove the rust of the ship outer plate. At the same time, the driving motor drives the worm to rotate, and the worm drives the two screws to rotate by meshing with the two worm wheels. The two screws drive the water tank to rise and fall through the threaded transmission with the corresponding ear plate, and the water tank drives the spray barrel to move vertically, so as to realize the washing of ship outer plates at different heights;

[0024] 3.

[0025] 4. In the present invention, a high-pressure water spraying rust removal device for ship outer plates is described.

The image processing module is used to grayscale, binarize and denoise the image. The analysis module is used to analyze the rust state. The judgment module is used to analyze the difficulty of flushing according to the rust state. The execution module is used to control the operation of the adjustment motor according to the difficulty of flushing. When encountering firmly attached heavy rust, the adjustment motor is controlled to drive the adjustment screw to rotate forward. At the same time, the adjustment screw drives the conductive frame to move to the right through the threaded transmission with the insulating plate, so that the resistor bar is connected in series with the high-pressure water pump. The part connected in series becomes smaller, and the part connected in series with the resistance bar and the driving motor becomes larger, so that the voltage provided to the high-pressure water pump increases and the voltage provided to the driving motor decreases, so that the high-pressure water pump increases the injection pressure, and at the same time the driving motor speed decreases, thereby increasing the speed at which the water tank descends, so that the speed of the high-pressure nozzle movement can be reduced while the injection pressure is increased to ensure that the thick rust firmly attached is thoroughly washed away. On the contrary, when encountering a relatively weak rust layer or relatively new rust, the injection pressure can be automatically lowered to remove the surface rust, thereby reducing the impact on the ship's outer plate, protecting the integrity of the primer and the substrate, and at the same time adjusting the speed of the high-pressure nozzle movement to increase the rust removal speed;

[0026] 5. In the present invention, the high-pressure water spraying rust removal device for ship outer plates, during the water spraying process, the connecting spring keeps the runner in contact with the ship outer plate under the action of its own elastic force, so that the U-shaped frame moves horizontally following the concave and convex of the ship outer plate, so that when the distance between the high-pressure nozzle and the ship outer plate becomes larger, the U-shaped frame moves to the right, thereby driving the installation frame, the insulating plate and the conductive frame to move to the right, so that the flushing force becomes shorter and the moving speed of the high-pressure nozzle decreases, so that the ship outer plate at a longer distance can be sprayed for rust removal, and at the same time, when the distance between the high-pressure nozzle and the ship outer plate becomes smaller, the U-shaped frame moves to the left, thereby driving the installation frame, the insulating plate and the conductive frame to move to the left, thereby reducing the flushing force and increasing the moving speed of the high-pressure nozzle, thereby avoiding damage to the ship outer plate caused by excessive flushing;

[0027] 6. In the present invention, the high-pressure water spraying rust removal device for ship outer plates can automatically adjust the spraying pressure and speed according to the spraying distance and the degree of rust on the ship outer plates through the monitoring mechanism and the spraying mechanism, thereby ensuring that the structure of the thick rust layer is effectively destroyed and avoiding damage to the substrate.

The rack 702 drives the connecting shaft 7 and the rotating arm 703 to rotate by meshing with the transmission gear. The rotating arm 703 drives the round rod 704 to perform circular motion. The round rod 704 drives the guide seat 402 to move back and forth through the cooperation of the sliding frame 705 and the vertical rod 706, thereby driving the spray tube 4 and the multiple high-pressure nozzles 401 to move vertically and shake back and forth, thereby achieving comprehensive water spraying and rust removal of the ship's outer plate;

[0060] During the water spraying process, the image of the ship's outer plate is obtained through the camera 16 and transmitted to the controller 10, the signal receiving module 1001 is used to receive image information, the image processing module 1002 is used to grayscale, binarize and denoise the image, the analysis module 1003 is used to analyze the rust state, the judgment module 1004 is used to analyze the difficulty of flushing according to the rust state, and the execution module 1005 is used to control the operation of the adjustment motor 15 according to the difficulty of flushing. When encountering firmly attached heavy rust, the adjustment motor 15 is controlled to drive the adjustment screw 17 to rotate forward. While the adjustment screw 17 rotates forward, it drives the conductive frame 901 to move to the right through the threaded transmission with the insulating plate 14, so that the part of the resistor bar 9 connected in series with the high-pressure water pump 3 The resistance bar 9 and the driving motor 505 are connected in series, and the resistance bar 9 and the driving motor 505 are connected in series, so that the voltage provided to the high-pressure water pump 3 is increased and the voltage provided to the driving motor 505 is reduced, so that the high-pressure water pump 3 increases the injection pressure, and the driving motor 505 is driven at a lower speed, thereby increasing the speed of the water tank 2 descending, so that the speed of the high-pressure nozzle 401 can be reduced while the injection pressure is increased to ensure that the thick rust firmly attached is thoroughly washed away. On the contrary, when encountering a relatively weak rust layer or relatively new rust, the injection pressure can be automatically lowered to remove the surface rust, thereby reducing the impact on the outer plate of the ship, protecting the integrity of the primer and the substrate, and at the same time adjusting the speed of the high-pressure nozzle 401 to increase the rust removal speed;

[0061] At the same time, during the water spraying process, the connecting spring 802 keeps the wheel 805 in contact with the outer plate of the ship under the action of its own elastic force, so that the U-shaped frame 8 moves horizontally following the convexity and concavity of the outer plate of the ship, so that when the distance between the high-pressure nozzle 401 and the outer plate of the ship becomes larger, the U-shaped frame 8 moves to the right, thereby driving the installation frame 13, the insulating plate 14 and the conductive frame 901 to move to the right, so that the flushing force becomes shorter and the moving speed of the high-pressure nozzle 401 decreases, so that the outer plate of the ship at a farther distance can be sprayed for rust removal, and at the same time, when the distance between the high-pressure nozzle 401 and the outer plate of the ship becomes smaller, the U-shaped frame 8 moves to the left, thereby driving the installation frame 13, the insulating plate 14 and the conductive frame 901 to move to the left, thereby reducing the flushing force and increasing the moving speed of the high-pressure nozzle 401, thereby avoiding damage to the outer plate of the ship caused by excessive flushing.
