Description

Technical Field

[0001] This utility model relates to the field of ship hull spraying technology, specifically to a device for spraying paint on the surface of a ship hull. Background Technology

[0002] Hull painting is a complex engineering project involving corrosion prevention, anti-fouling, and aesthetics. The construction process includes surface cleaning, sandblasting, and weld grinding. The steel plate temperature must be controlled above the dew point, and attention must be paid to weather and wind speed. Using a high-altitude construction platform and manual spraying with spray guns is a common method. However, spraying paint in an open space is easily affected by external airflow, leading to paint spillage, environmental pollution, and significant hazards to spraying personnel. This method requires personnel to wear heavy protective clothing and respirators, is labor-intensive and inflexible, and is dangerous due to the risk of paint spillage and environmental pollution.

[0003] A search revealed patent number CN201520632646.1, which proposes an automatic ship painting robot that can simulate painting workers, reducing the labor input in shipyards and improving work efficiency. However, during operation, in order to avoid contaminating the painting surface with wheels, it can only spray in a fixed single direction and cannot spray up and down repeatedly, resulting in low painting efficiency. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing ship hull surface paint spraying equipment can only spray from one end, and cannot perform efficient spraying in a circulating manner.

[0005] To solve the above technical problems, the present invention provides the following technical solution: The present invention proposes a paint spraying device for ship hull surface, including a base, four sets of magnetic rollers at the four corners of the bottom of the base, the base being a cavity structure with an open top and a paint storage compartment inside the base, support columns at the four corners of the top of the base and a U-shaped frame at the top of the four sets of support columns, and a spraying structure for spraying within the frame.

[0006] The spraying structure includes a sliding plate that slides on the inner side wall of the frame. The sliding plate is equipped with an electric telescopic rod, and the free end of the electric telescopic rod extends through to the bottom of the sliding plate. It also includes a spray plate on the free end of the electric telescopic rod. The bottom of the spray plate is equipped with a spray head. A liquid pump is provided on one side of the base. The inlet end of the liquid pump is connected to the inside of the paint storage chamber through an inlet pipe. The outlet end of the liquid pump is connected to the spray head.

[0007] Adjusting screws are rotatably provided on both sides of the frame. A drive motor is provided on one side of the frame, and the power output shaft of the drive motor is connected to the adjusting screws. The adjusting screws pass through and are threadedly connected to the slide plate.

[0008] Preferred technical solution 1: Two sets of guide rods are symmetrically provided on the top of the spray plate, and the upper end of the guide rods slides through the plate.

[0009] Preferred technical solution 2: A protective cover is also provided on the outside of the spray plate, and a distance sensor is provided on the side wall of the protective cover for accurate detection of the spraying distance.

[0010] Preferred technical solution 3: The bottom of the skateboard is also equipped with a monitoring camera.

[0011] Preferred technical solution four: A paint injection pipe is provided on one side of the base and is connected to the inside of the paint storage chamber, and fixing blocks are provided on both sides of the base.

[0012] Preferred technical solution five: The side wall of the base is also equipped with a controller. The electric telescopic rod, drive motor, liquid pump and distance sensor are all electrically connected to the controller. The controller and the monitoring camera are both equipped with built-in wireless transmission modules and connected to external terminals.

[0024] Example 1

[0025] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: a paint spraying device for the surface of a ship hull includes a base 1, four sets of magnetic rollers 2 are provided at the four corners of the bottom of the base 1 for adhering to the outer shell of the ship hull to ensure that the movement is close to the ship hull and stable. The base 1 is a cavity structure with an open top and a paint storage chamber 3 is provided inside the base 1. Support columns 4 are provided at the four corners of the top of the base 1 and a U-shaped frame 5 is provided at the top of the four sets of support columns 4. A spraying structure for spraying is provided inside the frame 5.

[0026] like Figure 2 As shown, the spraying structure includes a slide plate 6 that slides on the inner wall of the frame 5. An electric telescopic rod 7 is provided on the slide plate 6, and the free end of the electric telescopic rod 7 extends through to the bottom of the slide plate 6. It also includes a spray plate 8 provided on the free end of the electric telescopic rod 7. A spray head 9 is provided at the bottom of the spray plate 8. A liquid pump 10 is provided on one side of the base 1. The liquid inlet end of the liquid pump 10 is connected to the inside of the paint storage chamber 3 through the liquid inlet pipe. The liquid outlet end of the liquid pump 10 is connected to the spray head 9.

[0027] To facilitate adjustment of the spraying position when the spraying structure moves up and down (i.e., the nozzle is at the lower end when moving upwards and at the upper end when moving downwards), and to prevent the rollers from contaminating the spraying surface, adjusting screws 11 are rotatably installed on both sides of the frame 5. A drive motor 12 is installed on one side of the frame 5, and the power output shaft of the drive motor 12 is connected to the adjusting screws 11. The adjusting screws 11 pass through and are threadedly connected to the slide plate 6. To facilitate observation of the spraying quality, a monitoring camera 16 is also installed at the bottom of the slide plate 6.

[0028] The base 1 is also equipped with a controller 19 on its side wall. The electric telescopic rod 7, drive motor 12, liquid pump 10 and distance sensor 15 are all electrically connected to the controller 19. The controller 19 and the monitoring camera 16 are both equipped with a built-in wireless transmission module and can be connected to an external terminal to operate and observe the spraying situation in real time.

[0029] Example 2

[0030] Based on Example 1, such as Figure 4 As shown, to increase the stability of the spray plate 8 during lifting, two sets of guide rods 13 are symmetrically arranged on the top of the spray plate 8, and the upper ends of the guide rods 13 are slidably mounted on the slide plate 6. In order to reduce the pollution of the environment by paint mist and to accurately control the spraying distance, a protective cover 14 is also fitted on the outside of the spray plate 8. A distance sensor 15 is provided on the side wall of the protective cover 14 for accurately detecting the spraying distance.

[0031] like Figure 2 As shown, a paint injection pipe 17 is provided on one side of the base 1 and is connected to the inside of the paint storage chamber 3. Fixing blocks 18 are also provided on both sides of the base 1. The device can be lifted upward by winding the rope around the fixing block 18, while the device moves downward by its own gravity. The other end of the rope is received by the winding mechanism.

[0032] In practical use, the device is lifted upwards by winding a rope around the fixed block 18, while simultaneously moving downwards using its own gravity. The other end of the rope is received by a winding mechanism. During upward movement, the nozzle is positioned at the lower end, and during downward movement, the spraying position is at the upper end, preventing the rollers from contaminating the spraying surface. The spraying distance is accurately detected by the distance sensor 15, and the electric telescopic rod 7 is activated to push the slide plate 6 downwards and spray through the spray head 9. When the spraying end needs to be adjusted, the position can be adjusted by driving the adjusting screw 11 through the drive motor 12. The monitoring camera 16 is connected to an external terminal, allowing real-time observation of the spraying situation.

[0033] In addition, the controller 19, electric telescopic rod 7, drive motor 12, liquid pump 10 and distance sensor 15 mentioned in this embodiment, as well as their matching power supply and control switch, are provided by the manufacturer. The circuits, electronic components and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated.
