[0001] This utility model relates to the field of photovoltaic cable laying technology, specifically to a marine photovoltaic cable laying device. Background Technology

[0002] Offshore photovoltaic (PV) cable laying refers to the process of transmitting electricity generated by a PV power generation system to land or energy storage devices via submarine or surface cables. This process includes cable selection, route surveying, laying construction, and subsequent maintenance, and must consider factors such as the marine environment, corrosion resistance, mechanical strength, and insulation performance. Laying methods include burying, suspending, or fixing to the seabed to ensure safe, reliable, and efficient power transmission while minimizing impact on the marine ecosystem. This is a crucial step in grid connection for offshore PV projects, directly affecting system stability and power generation efficiency.

[0003] During the laying of offshore photovoltaic cables, traditional laying devices have defects: when the floating body sways due to the action of waves, the cable is prone to loosening. This loosening will cause unexpected changes in the curvature of the cable, which will directly affect the laying quality of the cable. Utility Model Content

[0004] The purpose of this invention is to provide a device for laying marine photovoltaic cables, which solves the problem that existing farmland weeding devices cannot remove stones before weeding, and that during weeding operations, hard objects such as stones will directly damage the blade when they collide with the cutting blade, increasing the blade wear rate.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: through the coordinated cooperation between the damping component, the first tensioning component and the second tensioning component, an effective tension force can be applied to the cable, which solves the problem of cable loosening caused by insufficient tension effect in traditional laying devices, avoids the impact of abnormal changes in cable curvature on the laying quality, improves the tension stability of the cable, and thus ensures the improvement of the overall laying effect.

[0020] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0021] This embodiment provides a technical solution: a device for laying offshore photovoltaic cables, such as... Figure 1-4 As shown, it includes:

[0022] The laying mechanism 100 includes a float 110, at least two paddles 120 symmetrically arranged at the bottom of the float 110, a cable laying reel 130 fixedly installed on the top of the float 110 for laying cables, and a laying groove 140 opened on the top of the float 110 to cooperate with cable laying.

[0023] The anti-loosening mechanism 200 includes a damping component 210 for damping the cable release, a first tensioning component 220 for tensioning the cable, and a second tensioning component 230 for double tensioning the cable.

[0024] The coordinated action of the damping component 210, the first tensioning component 220, and the second tensioning component 230 applies effective tension to the cable, solving the problem of cable loosening caused by insufficient tension in traditional laying devices, avoiding the impact of abnormal changes in cable curvature on laying quality, improving cable tension stability, and thus ensuring the improvement of overall laying effect.

[0025] Specifically, the damping component 210 includes two fixed bent rods 211 fixedly installed on the top of the float 110, a guide ring 212 fixedly installed between the two fixed bent rods 211 and used for guiding the cable, a connecting frame 213 set on the top of the guide ring 212, and a damping wheel 214 rotatably installed on the inner side of the connecting frame 213 and used for damping the cable release.

[0026] Furthermore, a first spring 215 is fixedly mounted on the surface of the guide ring 212, and the top end of the first spring 215 is fixedly connected to the connecting bracket 213.

[0027] The first spring 215 is used to maintain tension on the connecting frame 213, which in turn drives the damping wheel 214 to keep pressing the cable passing through the guide ring 212, so that the cable is subjected to damping force and the cable is prevented from loosening due to the cable feeding wheel 130 feeding the cable too fast.

[0028] Preferably, the first tensioning component 220 includes a fixed frame 221 fixedly mounted on the top of the float 110, at least two second springs 222 fixedly mounted on the surface of the fixed frame 221, a movable frame 223 fixedly mounted on the other end face of the second springs 222, and a first pulley 224 rotatably mounted inside the movable frame 223 for tensioning the cable.

[0029] The second spring 222 is used to pull the movable frame 223, so that the movable frame 223 tends to move closer to the fixed frame 221. In turn, the movable frame 223 drives the first pulley 224 to keep the cable taut and prevent the cable from loosening during laying.

[0030] Furthermore, the surface of the fixed frame 221 is provided with a connecting groove, and the end of the movable frame 223 passes through the connecting groove.

[0031] The connecting groove is used to limit the movement of the mobile frame 223, thereby improving the stability of the mobile frame 223 during movement, and thus improving the tensioning effect of the first pulley 224 on the cable, preventing the buoy 110 from swaying and causing sudden changes in the curvature of the cable.

[0032] Furthermore, the second tensioning component 230 includes two spring-loaded hinges 231 fixedly mounted on the top of the float 110, a connecting plate 232 rotatably mounted on the surface of the spring-loaded hinges 231, and a second pulley 233 fixedly mounted between the two connecting plates 232 for applying pressure to the cable.

[0033] The spring-loaded hinge 231 is used to apply elastic torque to the connecting plate 232. The connecting plate 232 drives the second pulley 233 to squeeze the cable passing above the second pulley 233, so that the cable is tensioned. The double tensioning of the cable can effectively prevent the cable from becoming loose and causing poor laying effect.

[0034] In use: the first spring 215 is used to maintain tension on the connecting frame 213, and the connecting frame 213 drives the damping wheel 214 to maintain the compression of the cable passing through the inside of the guide ring 212, so that the cable is subjected to damping force;

[0035] The second spring 222 is used to pull the movable frame 223, so that the movable frame 223 maintains the tendency to move closer to the fixed frame 221, and then the movable frame 223 drives the first pulley 224 to maintain the tension of the cable.

[0036] The spring-loaded hinge 231 is used to apply elastic torque to the connecting plate 232. The connecting plate 232 drives the second pulley 233 to squeeze the cable passing above the second pulley 233, so that the cable is tensioned, thus doubly tensioning the cable.

[0037] In summary, through the coordinated operation of the damping component 210, the first tensioning component 220, and the second tensioning component 230, an effective tension force can be applied to the cable, solving the problem of cable loosening caused by insufficient tension in traditional laying devices, avoiding the impact of abnormal changes in cable curvature on the laying quality, improving the tension stability of the cable, and thus ensuring the improvement of the overall laying effect.

[0038] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
