Description

Technical Field

[0001] The invention relates to the technical field of ship rust removal, and in particular to a ship rust removal high-pressure water jet system and a working method thereof. Background Art

[0002] Rust removal and cleaning of ships is an important business in the shipbuilding industry. It is an indispensable part of shipbuilding and ship repairing, and is the first step before ship painting. In addition, since the outer wall of the ship is immersed in seawater for a long time, it is eroded by seawater and inevitably corroded. In order to increase the service life of the ship and increase the safety of use, when the outer wall of the ship rusts to a certain extent, rust removal and cleaning must be carried out. Traditional rust removal methods such as manual grinding and chemical treatment are not only inefficient, but also pollute the environment and have a certain impact on human health.

[0003] The method of rust removal by high-pressure water jetting is widely used due to its low pollution and high efficiency. Different jet angles will affect the impact pressure and shear stress distribution of the wall surface during high-pressure water jetting. The appropriate impact angle can increase the dynamic performance of the jet and effectively improve the cleaning efficiency. The experimental results show that when the target distance is small, the optimal impact angle changes with the change of the target distance, and basically shows a decreasing trend; when the target distance is large, the optimal impact angle is relatively stable. Appropriately increasing the impact angle and target distance can reduce the energy loss of the jet to a certain extent, but excessive impact angle and target distance will aggravate the energy loss. The optimal jet angle for ship high-pressure water rust removal is 50-70 degrees. At present, most rust removal methods use manual handheld high-pressure nozzles to achieve jet rust removal. However, this control method is difficult to ensure a constant jet angle and jet distance, which will affect the rust removal effect; Therefore, we propose a ship rust removal high-pressure water jet system and its working method to solve this problem.

[0023] Preferably, hooks are fixedly mounted on both the front and rear sides of the housing.

[0024] The present invention also provides a working method of the above-mentioned ship rust removal high-pressure water jet system, comprising the following steps:

[0025] S1: Pull the square plate to drive the insertion rod out of the slot, then rotate the square frame to drive the adjusting screw to rotate, and the adjusting screw drives the injection nozzle to slide on the outside of the injection pipe through the threaded transmission with the adjusting plate, so as to adjust the extended length of the injection nozzle. After the adjustment is completed, loosen the square frame and the square plate, so that the square plate is reset under the action of the tension spring, and drives the insertion rod to be inserted into the slot to lock the square frame and the adjusting screw;

[0026] S2: Connect the left end of the water inlet pipe to the water pipe, connect the drive motor and the travel motor to the wires, tie the rope to the outside of the hook, and then hang the casing on the outside of the ship and adjust it to the height required for rust removal, then bring the rope close to the ship, so that the two permanent magnets on the casing are adsorbed on the outer surface of the ship, and the front and rear wheels are in contact with the outer surface of the ship;

[0027] S3: By sending a control signal to the controller remotely, the travel motor is controlled to start, and the travel motor drives the driving gear to rotate. The driving gear drives the front axle and the front wheel to rotate by meshing with the driven gear, so that the front wheel rolls on the outer surface of the ship, thereby driving the casing to move on the surface of the ship. While the casing moves, the rear wheel rolls, thereby driving the rear axle to rotate. The rear axle rotates vertically through the meshing of the driving bevel gear and the driven bevel gear. The vertical axis drives the crossbar to rotate and drives the two connecting frames to perform circular motion. The connecting frames move away from each other under the action of centrifugal force, and drive the two connecting plates to move away from each other. The two connecting plates drive the connecting rod to move upward by sliding with the connecting rod. The connecting rod drives the horizontal plate to move upward, and the horizontal plate drives the control switch to move upward, so that the control switch and the touch switch are squeezed against each other. After the control switch is squeezed, the control drive motor is started, thereby driving the impeller to rotate. While the impeller rotates, water is extracted through the water inlet pipe and introduced into the injection pipe and the injection nozzle for spraying. The rust and paint residue on the surface of the ship are washed by the high-pressure water flow. During the spraying process of the injection nozzle moving, the relative angle between the injection nozzle and the ship can be kept constant, thereby improving the washing effect. At the same time, the touch switch is squeezed and closed, so that the electromagnet is energized to generate magnetic attraction, thereby further adsorbing the ship to prevent the casing from falling off under the influence of the high-pressure water flow;

[0028] S4. The image of the ship surface is acquired through the camera and transmitted to the controller. The controller analyzes the image to determine the degree of corrosion of the ship. When the corrosion is serious, the speed of the drive motor is increased and the speed of the travel motor is reduced, thereby increasing the flushing spray pressure and reducing the casing travel speed to ensure the flushing effect.

[0029] S5. The driving motor drives the active pulley to rotate, and the active pulley drives the connecting shaft to rotate through the transmission with the driven pulley, and drives the rotating plate to rotate synchronously. The rotating plate drives the two sliding frames to perform circular motion, so that they move away from each other under the centrifugal force of the counterweight plate, and drives the circular plate to move to the left through the pull rope. The circular plate drives the insulating plate to move to the left through the limit ring, and the insulating plate drives the conductive cylinder fixed inside it to move to the left, so that the resistance of the resistor bar connected to the electromagnet circuit is reduced, and the faster the speed of the driving motor, the lower the resistance of the resistor bar connected to the electromagnet circuit, so that the current passing through the electromagnet is larger, the magnetic force generated is larger, and the electromagnet has a greater adsorption force on the ship, which further avoids the high-pressure water flow causing the casing to fall off;

[0030] S6. When the casing falls off from the outside of the ship, the rear wheel stops rotating, causing the vertical axis to stop rotating. The connecting frame is reset under the action of the compression spring and drives the cross plate and the control button to move downward. After the control button is released, the drive motor stops running, thereby stopping the flushing work.

[0031] Compared with the prior art, the present invention provides a ship rust removal high-pressure water jet system and a working method thereof, which have the following beneficial effects:

[0032] (1) The extension length of the jet nozzle can be adjusted by the adjustment mechanism, so that the distance between the jet nozzle and the outer surface of the ship can be adjusted as needed, and the fixing stability is high after adjustment to prevent loosening;

[0033] (2) The spraying mechanism can spray and remove rust from the ship while the casing moves along the outer surface of the ship, reducing manpower consumption and maintaining a constant spraying angle, thereby improving the rust removal effect;

[0034] (3) The camera and the controller can increase the water spray pressure and reduce the moving speed of the casing when encountering areas with a large degree of rust, thereby ensuring the flushing effect;

[0035] (4) By increasing the flushing pressure and improving the adsorption effect on the ship, it is prevented from falling off, and when accidental falling off occurs, the drive motor can be turned off in time to stop further spraying. BRIEF DESCRIPTION OF THE DRAWINGS

The vertical axis 404 drives the cross bar 405 to rotate and drives the two connecting frames 406 to perform circular motion. The connecting frames 406 move away from each other under the action of centrifugal force, and drive the two connecting plates 413 to move away from each other. The two connecting plates 413 drive the sliding cooperation with the connecting rod 410 The connecting rod 410 moves upward, and the connecting rod 410 drives the horizontal plate 414 to move upward, and the horizontal plate 414 drives the control switch 411 to move upward, so that the control switch 411 and the touch switch 412 are squeezed against each other. After the control switch 411 is squeezed, the control drive motor 602 is started, thereby driving the impeller 601 to rotate. While the impeller 601 rotates, water is extracted through the water inlet pipe 603 and introduced into the injection pipe 2 and the injection nozzle 3 for spraying. The rust and paint residue on the surface of the ship are washed by the high-pressure water flow. During the spraying process of the injection nozzle 3 moving, the relative angle between the injection nozzle 3 and the ship can be kept constant, thereby improving the washing effect. At the same time, the touch switch 412 is squeezed and closed, so that the electromagnet 14 is energized to generate magnetic attraction, thereby further adsorbing the ship to prevent the housing 1 from falling off under the influence of the high-pressure water flow;

[0073] S4, the image of the ship surface is acquired through the camera 15 and transmitted to the controller 11, the controller 11 analyzes the image to determine the degree of corrosion of the ship, and when the corrosion is serious, the speed of the drive motor 602 is increased and the speed of the travel motor 504 is reduced, thereby increasing the flushing spray pressure and reducing the travel speed of the housing 1 to ensure the flushing effect;

[0074] S5. The driving pulley 7 is driven to rotate by the driving motor 602. The driving pulley 7 drives the connecting shaft 9 to rotate through the transmission with the driven pulley 8, and drives the rotating plate 26 to rotate synchronously. The rotating plate 26 drives the two sliding frames 25 to perform circular motion, so that they move away from each other under the centrifugal force of the counterweight plate 27, and drives the circular plate 22 to move leftward through the pull rope 23. The circular plate 22 drives the insulating plate 20 to move leftward through the limit ring. The insulating plate 20 drives the conductive cylinder 21 fixedly connected thereto to move leftward, so that the resistance of the resistor bar 18 connected to the electromagnet 14 circuit is reduced, and the faster the speed of the driving motor 602, the lower the resistance of the resistor bar 18 connected to the electromagnet 14 circuit, so that the current passing through the electromagnet 14 is larger, the magnetic force generated is larger, and the electromagnet 14 has a greater adsorption force on the ship, which further prevents the casing 1 from falling off due to high-pressure water flow;

[0075] S6. When the casing 1 falls off from the outside of the ship, the rear wheel 401 stops rotating, causing the vertical shaft 404 to stop rotating. The connecting frame 406 is reset under the action of the compression spring 407 and drives the horizontal plate 414 and the control button to move downward. After the control button is released, the driving motor 602 stops running, thereby stopping the flushing work.

[0076] In this embodiment, when in use, the extension length of the injection nozzle 3 can be adjusted by the provided adjustment mechanism, so that the distance between the injection nozzle 3 and the outer surface of the ship can be adjusted as needed, and the fixed stability after adjustment is high to prevent loosening; the provided injection mechanism can spray and remove rust on the ship while the casing 1 moves along the outer surface of the ship, reducing manpower consumption, and can maintain a constant injection angle, thereby improving the rust removal effect; the provided camera 15 cooperates with the controller 11 to increase the water injection pressure and reduce the moving speed of the casing 1 when encountering an area with a large degree of rust, thereby ensuring the flushing effect; and can increase the adsorption effect on the ship while increasing the flushing pressure, thereby avoiding falling off, and can timely shut down the drive motor 602 to stop continuing to spray when unexpected falling off occurs.
