[0010] Furthermore, transmission gears are fixedly mounted on the rear ends of the two connecting shafts through bearings penetrating the guide frame, and the two transmission gears are meshed and connected.

[0011] Furthermore, a synchronous wheel three is fixedly installed on the front end of the connecting shaft located at the upper part through a bearing passing through the guide frame, and a synchronous wheel four is fixedly installed on the front end of the rotating shaft through a bearing passing through the U-shaped seat, and the synchronous wheel four is transmission-connected to the synchronous wheel three through a synchronous belt.

[0015] Furthermore, a plurality of mounting holes are evenly provided on the front and rear parts of the top wall of the workbench, and the driving motor and the feeding pump are electrically connected to an external power supply and a controller.

[0016] The present invention has the following beneficial effects: (1) The underwater cable laying device of the water conservancy project drives the winding roller to convey the cable outward through the driving motor. The winding roller shaft drives the synchronous wheel 2, the synchronous belt, the synchronous wheel 1, and the reciprocating screw to rotate. The sliding seat moves back and forth along the reciprocating screw and the outer wall of the limit rod. The moving direction of the sliding seat is the same as the winding direction of the cable, so that the cable always keeps a vertical state with the winding roller when conveyed outward. The sliding seat drives the U-shaped seat, the auxiliary wheel, the triangular support seat and the guide frame to move. The guide frame drives the supporting roller to roll along the inner wall of the travel track at the top of the supporting slide rail, which has the function of supporting the movement of the guide frame. After the cable passes through the auxiliary wheel and the guide wheel, the guide frame will also follow the movement of the triangular support seat and the sliding seat, so that the moving direction of the guide frame is also the same as the winding direction of the cable, thereby improving the transmission efficiency of the cable laying and reducing the wear during transportation. It can move according to the winding direction of the cable, reduce the transmission resistance of the cable, and avoid damage to the cable.

[0017] (2) The water conservancy project uses an underwater cable laying device. When the auxiliary wheel is driven by the friction of the cable itself, the auxiliary wheel drives the rotating shaft to rotate, and at the same time, the rotating shaft drives the synchronous wheel four to rotate. The synchronous wheel four drives the synchronous wheel three to rotate through the synchronous belt. When the synchronous wheel three rotates, it will drive the connecting shaft and the cleaning roller located at the upper part to rotate, so that the connecting shaft and the cleaning roller located at the upper part will drive the corresponding transmission gear to rotate when they rotate, and then drive the transmission gear at the lower part that meshes with them to rotate synchronously. When the cleaning roller rotates, it will drive the cleaning brush to clean the surface of the cable, thereby reducing dust and impurities on the surface of the cable. At the same time, no additional power source is required to work, which can reduce production costs and save energy. At the same time, it provides a good and clean substrate for the subsequent spraying of paint on the cable surface.

[0018] (3) The water conservancy project uses an underwater cable laying device. The feed pump draws environmentally friendly paint that hardens when it comes into contact with water and has friction resistance from the inside of the material box through the feed pipe. The paint passes through the discharge pipe and enters the inside of the connecting pipe. The atomized paint is sprayed from the discharge nozzle and contacts the surface of the cable, so that the paint can evenly cover the outer surface of the cable. When the cable enters the water, the paint reacts with water and the water evaporates. The polyurethane resin molecular chains cross-link with each other to form a tough paint film. The molecular structure is tight and has good elasticity and wear resistance to withstand frequent friction. The VOC volatile organic compound content is low, non-toxic and odorless, meets environmental protection standards and will not pollute the water source. Therefore, when there is a tough paint film on the surface of the cable and it enters the water and rubs against mud, sand and stones, it can reduce the friction damage of the cable, increase the service life of the cable, and protect the cable during laying.

[0019] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The rear end of the winding roller 7 passes through the U-shaped frame 5 through a bearing and is fixedly mounted with a synchronous wheel 2 87. The bottom of the inner wall of the U-shaped frame 5 is fixedly mounted with a limit rod 82. The outer wall of the reciprocating screw rod 81 is screwed with a sliding seat 83. The top wall of the sliding seat 83 is fixedly mounted with a U-shaped seat 84. The inner wall of the U-shaped seat 84 is rotatably mounted with an auxiliary wheel 85 through a rotating shaft. The guide assembly 3 includes a guide frame 31, a triangular support seat 36 is fixedly installed on the left side of the bottom wall of the guide frame 31, the left side wall of the triangular support seat 36 is fixedly connected to the right side wall of the sliding seat 83, a plurality of guide wheels 32 are rotatably installed on the left and right sides of the inner wall of the guide frame 31, and a support wheel 37 is rotatably installed on the bottom right side of the inner wall of the guide frame 31.

[0025] In this embodiment, when the winding roller 7 conveys the cable outward, the guide component 3 cooperates with the moving component 8 so that the auxiliary wheel 85, the guide frame 31 and the guide wheel 32 will move synchronously following the cable's winding direction, always in a vertical state with the cable and the winding roller 7, thereby improving the conveying efficiency and reducing wear.

[0026] Specifically, the synchronous wheel 2 87 and the synchronous wheel 1 86 are connected through a synchronous belt transmission, the inner wall of the bottom of the sliding seat 83 is slidably connected to the outer wall of the limiting rod 82, and the rotating shaft passes through the U-shaped seat 84 through a bearing and is fixedly connected to the cleaning component 4.

[0027] In this embodiment, the inner wall of the bottom of the sliding seat 83 is slidably connected to the outer wall of the limiting rod 82 to prevent the sliding seat 83 from being displaced and flipped when moving, thereby improving the overall stability during movement.

[0028] Specifically, the inner wall of the guide frame 31 is fixedly connected to the cleaning assembly 4, the right side wall of the guide frame 31 is fixedly connected to the spray assembly 2, a supporting slide rail 33 is fixedly installed in the middle of the top wall of the workbench 1, a traveling track 34 is opened on the top wall of the supporting slide rail 33, and a supporting roller 35 is installed at the bottom of the guide frame 31, and the supporting roller 35 is rollingly connected to the inner wall of the traveling track 34.

[0029] In this embodiment, when the guide frame 31 moves, it drives the supporting roller 35 to roll along the travel track 34 on the top of the supporting slide rail 33 , which has a stable supporting effect on the guide frame 31 .

[0030] Specifically, the cleaning assembly 4 includes two connecting shafts 45, which are symmetrically arranged in an upper and lower manner. The two connecting shafts 45 are rotatably installed in the middle of the inner wall of the guide frame 31, and the outer walls of the two connecting shafts 45 are fixedly installed with cleaning rollers 41, and the outer walls of the two cleaning rollers 41 are evenly installed with a number of cleaning brushes 42.

[0031] In this embodiment, after the cable passes through the guide frame 31, it enters the position between the two cleaning rollers 41 and the cleaning brush 42. When the cable is continuously conveyed outwards, the cleaning brush 42 will clean the possible dust and impurities on the surface, providing a good substrate.

[0032] Specifically, at the rear ends of both connecting shafts 45, transmission gears 44 are fixedly installed through the guide frame 31 by bearings, and the two transmission gears 44 are meshed and connected.

[0033] In this embodiment, when the connecting shaft 45 at the top rotates, it will drive the transmission gear 44 to rotate, and then drive the lower transmission gear 44 meshed with it, so that the two connecting shafts 45 rotate in opposite directions, and then drive the cleaning rollers 41 and the cleaning brush 42 to rotate to clean the surface of the cable.

[0034] Specifically, at the front end of the upper connecting shaft 45, a third synchronous pulley 43 is fixedly installed through the guide frame 31 by a bearing, and at the front end of the rotating shaft, a fourth synchronous pulley 46 is fixedly installed through the U-shaped seat 84 by a bearing. The fourth synchronous pulley 46 is传动 connected to the third synchronous pulley 43 by a synchronous belt.

[0035] In this embodiment, when the cable passes through the auxiliary wheel 85, the friction force will drive it to rotate, and then drive the rotating shaft and the fourth synchronous pulley 46 to rotate, and drive the third synchronous pulley 43 to rotate through the transmission of the synchronous belt, reducing the setting of the power source and lowering the production cost.

[0036] Specifically, the spraying assembly 2 includes a feeding pump 21, the bottom wall of the feeding pump 21 is fixedly connected to the top wall of the workbench 1, and a material box 23 is fixedly installed at the front part of the top wall of the workbench 1.

[0037] In this embodiment, the feeding pump 21 is mainly used to extract the paint inside the material box 23. The paint filled inside the material box 23 is mainly an environmentally friendly paint that hardens after encountering water and has wear-resistant properties, which has a protective effect on the cable. When the cable enters the water and rubs against the sediment, it reduces the degree of friction damage on the surface of the cable.

[0038] Specifically, the feeding port of the feeding pump 21 is communicated with a feeding pipe 22, the front end of the feeding pipe 22 is communicated with the material box 23, and the discharging port of the feeding pump 21 is communicated with a discharging pipe 24.

[0039] In this embodiment, after the feeding pump 21 extracts the paint, it conveys it into the connecting pipe 25.

[0040] Specifically, the top end of the discharging pipe 24 is communicated with a connecting pipe 25. The connecting pipe 25 is in the shape of a "mouth", and the connecting pipe 25 is fixedly installed on the right side wall of the guide frame 31. A plurality of discharging nozzles 26 are uniformly communicated with the inner wall of the connecting pipe 25.

[0041] In this embodiment, the paint that enters the interior of the connecting tube 25 is sprayed into atomized paint through the discharge nozzle 26 and evenly covers the surface of the cable. When the cable enters the water, it reacts to form a dense coating with friction resistance on the surface of the cable, which prevents the cable from being damaged after friction with the mud and sand on the bottom of the water.

[0042] Specifically, a plurality of mounting holes are evenly provided on the front and rear parts of the top wall of the workbench 1 , and the driving motor 6 and the feeding pump 21 are electrically connected to an external power supply and a controller.

[0043] In this embodiment, the several mounting holes on the top wall of the workbench 1 are mainly used to install the entire device on a cable-laying vessel, and the driving motor 6 and the feeding pump 21 are controlled to work by an external controller.

[0044] During operation, the workbench 1 and the entire device are installed on the cable-laying vessel, and the external power supply and controller are electrically connected to the feeding pump 21 and the driving motor 6. The winding roller 7 of the cable installed around is now installed into the interior of the U-shaped frame 5, and the movable end of the cable passes through the auxiliary wheel 85 and enters the interior of the guide frame 31, and the movable end of the cable is guided to move outward after passing through the cleaning roller 41, the cleaning brush 42, the supporting wheel 37 and the connecting pipe 25. When the work is officially started, the winding roller 7 is driven by the driving motor 6 to start rotating, so that the winding roller 7 starts to transport the cable outward. When the winding roller 7 is rotating, the roller shaft drives the synchronous wheel 2 87 to rotate, and the synchronous wheel 2 87 drives the synchronous wheel 1 86 to rotate through the synchronous belt when the synchronous wheel 1 86 rotates. The reciprocating screw rod 81 will be driven to rotate, and then the sliding seat 83 will reciprocate left and right along the outer wall of the reciprocating screw rod 81 and the limit rod 82. The moving direction of the sliding seat 83 is the same as the winding direction of the cable, so that the cable always maintains a vertical state with the winding roller 7 when it is transported outward. When the sliding seat 83 moves, it will drive the U-shaped seat 84 and the auxiliary wheel 85 to move, and the sliding seat 83 will synchronously drive the triangular support seat 36 and the guide frame 31 to move. When the guide frame 31 moves, it will drive the supporting roller 35 to roll along the inner wall of the travel track 34 at the top of the supporting slide rail 33, which has the function of supporting the movement of the guide frame 31. After the cable passes through the auxiliary wheel 85 and the guide wheel 32, the friction force on the cable surface will drive the auxiliary wheel 85 and the guide wheel 32 to rotate. The guide frame 31 also moves along with the movement of the triangular support seat 36 and the sliding seat 83, so that the moving direction of the guide frame 31 is the same as the winding direction of the cable, thereby improving the transmission efficiency of the cable laying and reducing the wear during transportation. When the auxiliary wheel 85 is driven by the friction force of the cable itself, the auxiliary wheel 85 drives the rotating shaft to rotate, and at the same time, the rotating shaft drives the synchronous wheel four 46 to rotate, and the synchronous wheel four 46 drives the synchronous wheel three 43 to rotate through the synchronous belt. When the synchronous wheel three 43 rotates, it will drive the upper connecting shaft 45 and the cleaning roller 41 to rotate, so that the upper connecting shaft 45 and the cleaning roller 41 will drive the corresponding transmission gear 44 to rotate when they rotate, and then drive the lower transmission gear 44 meshing with it to rotate synchronously, so as to clean the When the roller 41 rotates, it drives the cleaning brush 42 to clean the cable surface, reducing the dust and impurities on the cable surface. At the same time, the feeding pump 21 is started to extract environmentally friendly paint that hardens after contact with water and has friction resistance from the inside of the material box 23 through the feeding pipe 22, such as water-based polyurethane paint. The specific paint to be used needs to be selected according to the construction requirements. After passing through the discharge pipe 24, the paint enters the inside of the connecting pipe 25 and is sprayed from the discharge nozzle 26 to contact the cable surface, so that the paint can be evenly covered on the outer surface of the cable. When the cable enters the water, the paint reacts with water and the water evaporates. The molecular chains of the polyurethane resin cross-link with each other to form a tough paint film. The molecular structure is tight and has good elasticity and wear resistance to withstand frequent friction.The VOC content is low, non-toxic and odorless, and it meets environmental standards and will not pollute water sources. Therefore, when the cable surface has a tough paint film and enters the water and rubs against mud, sand, and stones, it can reduce the friction damage of the cable, increase the service life of the cable, and protect the cable when it is laid.
