Description

Technical Field

[0001] The invention relates to the technical field of paint spraying equipment, in particular to an underwater paint touch-up device for ship lock repair. Background Art

[0002] Ship lock refers to a kind of "navigation structure", which is mainly composed of lock chamber, lock head, gate, pilot channel and corresponding equipment. In natural rivers, due to the regulation of flow, channelization and navigation, and in canals due to the limitations of terrain conditions and water surface slope, it is necessary to have a stepped longitudinal section to form a concentrated water surface drop. Therefore, it is necessary to use special navigation structures to allow ships to pass through the drop directly. When the ship travels from downstream to upstream, the water level in the chamber drops to the same level as the downstream water level, and then the gate of the downstream lock head is opened, the ship enters the lock chamber, the gate is closed, and water is poured. After the water level rises to the same level as the upstream water level, the gate of the upstream lock head is opened, and the ship can leave the lock and sail upstream through the upstream pilot channel. When the ship travels from upstream to downstream, the lock operation procedure is the opposite. The lock gate of the ship lock is immersed in water for a long time, and is impacted by the flow of floating objects and sediment in the water. The protective paint layer on the surface of the gate is easily worn, so that the internal steel door plate is exposed to water and corroded. Therefore, it is necessary to regularly repaint the worn paint layer on the gate plate.

[0003] For example, CN112156928A discloses a ship maintenance machine for underwater precise paint touch-up and maintenance of ships, including a machine body, a paint touch-up block cavity with an opening downward is provided in the machine body, a paint touch-up block is provided on the front and rear walls of the paint touch-up block cavity and slides up and down, and a paint spraying cavity with an opening downward is provided in the paint touch-up block. By moving in line with the bottom of the ship underwater, when the detection device detects where the paint has fallen, the paint touch-up device covers the area that needs to be touched up, drains the water through the drainage device, and the grinding device grinds the device that needs to be touched up. After the grinding is completed, the paint spraying device sprays paint, so that the ship can also touch up the exposed areas of the bottom of the ship underwater, without having to remove the entire ship from the water before touching up the paint, which can better maintain the ship and reduce the cost of maintenance. However, the existing underwater paint touch-up device directly applies the paint by spraying paint, and it is difficult to control the uniformity of the thickness of the sprayed paint layer.

[0004] Therefore, a device for underwater paint repairing of ship lock is introduced. Summary of the invention

[0034] The paint touch-up part 6 includes a hollow turntable 61 fixedly connected to the end of the guide tube 13 and a smoothing scraper 62 fixedly connected to both ends of the side wall of the end of the hollow turntable 61. An annular groove is provided at the edge of the outer wall on one side of the fixed end of the hollow turntable 61. The end of the hydraulic rod 15 is movably engaged in the annular groove. Paint spraying holes 63 are evenly spaced on the outer wall of the hollow turntable 61 outside the smoothing scraper 62. Paint spraying tubes 64 are evenly spaced and movably penetrated on the circumferential side wall of the hollow turntable 61. A clockwork spring 65 is fixedly connected to the outer wall at the end of the paint spraying tube 64 inside the hollow turntable 61. The outer end of the clockwork spring 65 is fixedly connected to the inner wall of the internal limiting cavity of the hollow turntable 61, and discharge holes 641 are evenly spaced on the outer wall of one side of the paint spray tube 64. A splash-proof wing plate 66 is fixedly connected to the outer wall of the paint spray tube 64 adjacent to the discharge hole 641, and a spiral guide groove 642 is opened on the outer wall of the paint spray tube 64 on the other side of the discharge hole 641. A spring rod 67 is fixedly connected to the side wall of the hollow turntable 61 outside the paint spray tube 64, and a counterweight ball 68 is fixedly connected to the end of the spring rod 67.

[0035] An accommodating cavity 101 is provided on both sides of the port of the equipment cabin 11, an electric push rod 102 is fixedly connected to the inner wall of the accommodating cavity 101, a sealing plate 103 is fixedly connected to the end of the electric push rod 102, and the sealing plate 103 is movably engaged in the accommodating cavity 101, and an isolation gasket 104 is fixedly connected to the side wall of the end of the waterproof shell 1 outside the port of the equipment cabin 11, and a liquid extraction valve pipe 105 is fixedly connected to the bottom of the isolation gasket 104, and the other end of the liquid extraction valve pipe 105 extends through the inside of the waterproof shell 1 and then the end thereof passes through the bottom thereof, and the water in the space to which the outside of the sealing plate 103 and the isolation gasket 104 belong is sucked out of the waterproof shell 1, thereby creating a waterless closed space after the isolation gasket 104 is attached to the gate plate, so as to facilitate the gate. The board is stably repainted, auxiliary propellers 106 are movably arranged at the middle of the outer walls on both sides of the waterproof shell 1 and at both ends of the bottom plate, and the shafts of the auxiliary propellers 106 are respectively connected to the output ends of the rotating motor arranged inside the equipment cabin 11. After the auxiliary propellers 106 on the outer walls on both sides of the waterproof shell 1 are selectively started, they are used to help push the equipment to move left and right, and the auxiliary propellers 106 at both ends of the bottom plate of the waterproof shell 1 are used to push the equipment to hover or float in the water. A protective cover tube 107 is fixedly connected to the outer wall of the waterproof shell 1 outside the auxiliary propeller 106, and a protective net 108 is fixedly connected to the inner wall at the port of the protective cover tube 107. The protective cover tube 107 and the protective net 108 are used to isolate and protect the auxiliary propeller 106.

[0036] Specifically, after the remote control device enters the water, it uses the underwater camera 31 to shoot and inspect whether the underwater part of the ship lock door panel is worn or peeled. When paint peeling is found, the main propeller 51 and the auxiliary propeller 106 are used to adjust the posture of the waterproof shell 1 so that its end is facing the peeled paint part of the ship lock door panel. Then the main propeller 51 pushes the waterproof shell 1 close to the ship lock door panel until the isolation gasket 104 at the end of the waterproof shell 1 fits the gate panel and covers the peeled paint part. The control box 3 controls the liquid extraction valve pipe 105 to suck the ship lock door panel, the isolation gasket 104 and the sealing plate The water filled in the lock chamber 103 is discharged from the waterproof housing 1 to create a waterless environment, and the electric push rod 102 is controlled to open the sealing plate 103. The hydraulic rod 15 is extended to push the hollow turntable 61 to move to the outside of the equipment cabin 11 port until the smoothing scraper 62 at the end of the hollow turntable 61 fits the outer wall of the ship lock door plate. When the hollow turntable 61 moves, it drives the guide tube 13 to move, so that all the protrusions on the outer wall of the guide tube 13 move to the inside of the gear cylinder 16, and the feed hose 14 transports the paint in the storage box 18 to the hollow turntable 61 through the guide tube 13. At this time, the electric push rod 102 is controlled to open the sealing plate 103, and the hydraulic rod 15 is extended to push the hollow turntable 61 to move to the outside of the equipment cabin 11 port until the smoothing scraper 62 at the end of the hollow turntable 61 fits the outer wall of the ship lock door plate. When the hollow turntable 61 moves, it drives the guide tube 13 to move, so that all the protrusions on the outer wall of the guide tube 13 move to the inside of the gear cylinder 16. The feed hose 14 transports the paint in the storage box 18 to move to the hollow turntable 61 through the guide tube 13. The machine drives the driving gear 17, and the driving gear 17 meshes with the gear cylinder 16 to drive the guide tube 13 and the hollow turntable 61 to rotate. When the hollow turntable 61 rotates, it is affected by the centrifugal force, and the counterweight ball 68 on the side wall thereof stretches the spring rod 67, so that the protrusion on the side wall of the counterweight ball 68 slides along the spiral guide groove 642 on the outer wall of the paint spraying tube 64, so that the paint spraying tube 64 rotates within a certain range, so that the discharge hole 641 on the paint spraying tube 64 faces the ship lock door plate, and at the same time, the splash-proof wing plate 66 on the paint spraying tube 64 is deflected away from the fixed end and tilted to rest on the ship lock. On the outer wall of the gate plate, the paint in the hollow turntable 61 is sprayed out from the paint spraying hole 63 and the discharge hole 641 respectively, and is evenly sprayed over a large area from the center to the edge through rotation to avoid excessive concentration during paint spraying. At the same time, the splash-proof wing plate 66 is tilted and fitted on the outer wall of the ship lock door plate to shield the paint sprayed out of the discharge hole 641 to prevent it from deviating from the ship lock door plate. The splash-proof wing plate 66 and the smoothing scraper 62 synchronously level the paint as the hollow turntable 61 rotates, thereby achieving uniform and automatic paint touch-up of the ship lock door plate within the circle cover of the isolation gasket 104, which is easy to use.

[0037] like Figure 4As shown, the end of the guide tube 13 extends to the inside of the hollow turntable 61, and a plugging head 131 is movably connected between the inner walls at the end port of the guide tube 13. The plugging head 131 is a hemispherical structure, and the shaft rod on one side of the plugging head 131 extends through to the outside of the side wall of the guide tube 13, and the end of the shaft rod is fixedly connected to a fixing rod 132, and the end of the fixing rod 132 is fixedly connected to a bracket, and the end of the bracket is fixedly connected to the inner wall of the port of one of the paint spray tubes 64; when the spherical surface of the plugging head 131 extends to the outside of the port of the guide tube 13, the clockwork spring 65 and the spring rod 67 both maintain a normal relaxation state. At this time, the splash-proof wing plate 66 is arranged vertically downward based on the paint spray tube 64, and the counterweight ball 68 is located at the end of the spiral guide groove 642 close to the hollow turntable 61.

[0038] Specifically, when the counterweight ball 68 stretches the spring rod 67 to push the paint spray tube 64 to rotate, the paint spray tube 64 synchronously drives the sealing head 131 to rotate between the inner walls at the end port of the guide tube 13 based on the fixed rod 132, so that the plane of the sealing head 131 faces downward, and the output port of the guide tube 13 is automatically opened through the rotation of the hollow turntable 61. At the same time, after the hollow turntable 61 stops rotating, the paint spray tube 64 automatically resets under the action of the clockwork spring 65, thereby driving the sealing head 131 to automatically block the output port of the guide tube 13 again, thereby realizing automatic connection and closed control of the paint supply to the output port of the guide tube 13, avoiding the waste caused by the overflow of the paint retained in the guide tube 13, and the problem of uneven paint thickness on the lock door panel.

The end of the elastic component 712 is fixedly connected to a moving rod 713. The end of the moving rod 713 extends through the outer side of the end of the positioning tube 711. A limited sliding groove 721 is provided on the outer wall of the side of the installation cross bar 72 corresponding to the moving rod 713. The end of the moving rod 713 is movably engaged in the limited sliding groove 721. The limited sliding groove 721 is close to the cleaning scraper 73. An adjusting rope 714 is fixedly connected to the inner wall at one end. After the adjusting rope 714 passes through the side wall at the end of the moving rod 713, the other end passes through the side wall of the end of the moving rod 713 in the positioning cylinder 711. The end of the moving rod 713 in the positioning cylinder 711 is fixedly connected to a sliding sleeve. The adjusting rope 714 on the outside of the moving rod 713 is movably sleeved in the sliding sleeve, and the end of the adjusting rope 714 is fixedly connected to the inner wall of the end of the positioning cylinder 711. A return spring 715 is fixedly connected between the side wall of the end of the moving rod 713 and the inner wall of the limiting slide groove 721.

[0042] Specifically, when the waterproof shell 1 moves toward the ship lock door plate, the cleaning scraper 73 vertically suspended at the center of the outer side of the isolation gasket 104 first contacts the ship lock door plate. In the process of the isolation gasket 104 moving to fit the ship lock door plate, the ship lock door plate reacts to the cleaning scraper 73. The cleaning scraper 73 pushes the moving rod 713 to move into the positioning cylinder 711 based on the installation cross bar 72, and squeezes the elastic component 712 on the bottom plate of the positioning cylinder 711. When the moving rod 713 moves into the positioning cylinder 711, it slides and pushes the adjusting rope 714, so that the side wall of the installation cross bar 72 is The adjusting rope 714 in the limiting slide groove 721 is continuously moved into the moving rod 713 and the positioning cylinder 711, so that the adjusting rope 714 pulls the mounting cross bar 72 on the outer wall at the end of the moving rod 713 to move toward the edges of both sides of the waterproof shell 1, so that the two cleaning scrapers 73 close together move along the center of the isolation gasket 104 to both sides thereof, and finally the cleaning scrapers 73 are suspended on both sides of the isolation gasket 104, so that the debris attached to the ship lock door panel is automatically scraped and cleaned during movement, so as to avoid the debris from affecting the adhesion of paint spraying, and no additional operating equipment is required for cleaning, which is convenient to use.

[0043] In order to enhance the cleaning effect of the lock door panel, Figure 6-Figure 8As shown, mounting cavities 74 are evenly spaced apart on the side wall of the cleaning scraper 73 away from the waterproof shell 1, and a magnetic roller 75 is movably connected between the inner walls of the upper and lower ends of the mounting cavity 74. The upper and lower ends of the outer walls on the opposite sides of the two cleaning scrapers 73 are respectively fixedly connected with support seats 76, and corresponding L-shaped shafts 77 are movably provided on the outer walls opposite to the support seats 76. The vertical axis of the L-shaped shaft 77 extends through the support seat 76 and is movably connected to the shaft of the magnetic roller 75. A spiral strip 78 is fixedly connected between the side walls opposite to the cross bar of the L-shaped shaft 77. The spiral strip 78 extends to the outside of the cleaning scraper 73 and is a component made of flexible material.

[0044] The magnetic roller 75 is arranged inside the mounting cavity 74 between the support seats 76. The end of the shaft of the magnetic roller 75 close to one end of the support seat 76 extends into the internal cavity of the cleaning scraper 73. The end of the shaft of the magnetic roller 75 is fixedly connected to a driving gear 751. The L-shaped shaft 77 extends vertically to the inside of the support seat 76 and the rear end is fixedly connected to a driven gear plate 771. The driven gear plate 771 is connected to the driving gear 751 through a chain. The driven gear plate 771 and the chain are only arranged at the end of the L-shaped shaft 77 on one side above or below the spiral strip 78 for transmission control.

[0045] Specifically, when the adjusting rope 714 pulls the installation horizontal bar 72 to move on the outer wall of the end of the moving rod 713 toward the edges of both sides of the waterproof shell 1, the two cleaning scrapers 73 close together move along the center of the isolation gasket 104 to both sides thereof, and finally the cleaning scrapers 73 are suspended on both sides of the isolation gasket 104, the cleaning scrapers 73 always slide against the outer wall of the ship lock door panel, thereby driving the magnetic roller 75 in the installation cavity 74 on the outer wall of the cleaning scraper 73 to roll against the ship lock door panel, and the magnetic roller 75 uses magnetic force to absorb the ship lock door panel to keep the equipment and the ship lock door panel in close contact and stable movement. At the same time, when the magnetic roller 75 rolls and rotates, the magnetic roller 75 uses the shaft rod to cooperate with the driving gear 751 and the chain to drive the driven gear plate 771 to rotate, and the driven gear plate 771 then drives the spiral bar 78 between the support seat 76 to rotate through the L-shaped shaft 77. When the cleaning scraper 73 moves along the center of the isolation gasket 104 to both sides thereof to clean the ship lock door panel, the spiral bar 78 rotates synchronously to wipe the paint-shedding part of the ship lock door panel. Through the staggered cleaning in the vertical and horizontal directions on the cleaning scraper 73 and the spiral bar 78, the cleaning effect of the debris attached to the paint-shedding part of the ship lock door panel is further guaranteed, which is convenient and practical.
