Description

Technical Field

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

[0002] With the increasing severity of global energy transition and climate change issues, solar photovoltaic power generation, as a green and clean energy source, has developed rapidly. Offshore solar energy resources are abundant, with vast water areas, not limited by land resources, and also possess advantages such as high power generation efficiency. Therefore, offshore photovoltaic power generation has become a research focus in recent years.

[0003] Currently, offshore floating photovoltaic power generation systems consist of: floating units, cable nets, buoys, and mooring structures. These components form a floating platform supporting the photovoltaic panels. The buoys are located outside the floating units. The mooring structure comprises a mooring system and an underwater anchoring structure. One end of the mooring passes through a hole in the buoy and is fixed to it. This mooring installation method is simple and convenient, but stress is concentrated at the hole in the buoy. Under the influence of wind and waves, relative friction easily occurs between the buoy and the mooring. After long-term use, the mooring is prone to breakage, and the hole in the buoy will continue to enlarge, ultimately affecting the buoy's buoyancy. Utility Model Content

[0004] The present invention aims to provide a mooring system connection device to solve the problems that current methods of connecting buoys and mooring systems can easily lead to mooring breakage and affect the buoy buoyancy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a mooring system connection device, comprising a connector and a mooring cable, the connector comprising a truss and a lug plate disposed on the truss, the truss being provided with a sealed chamber for providing buoyancy, the lug plate being fixed on the truss and located on the inner side of the truss, a hole being provided between the outer wall of the truss and the lug plate for the mooring cable to pass through and be wound, the truss being provided with a C-shaped rib plate for limiting the mooring cable, the open end of the C-shaped rib plate being fixed on the upper and lower surfaces of the lug plate, the C-shaped rib plate being symmetrically disposed on both sides of the hole, and the lug plate being provided with a limiting hole.

[0006] The principle of this scheme is as follows: the mooring cable is passed through the hole formed between the outer wall of the truss and the ear plate, and the mooring cable is wrapped and fixed to the outer wall of the truss. Then, the longitudinal and transverse cables of the cable net are fixed at the corresponding limiting holes. The truss structure is used to restrict the movement of the mooring cable and maintain the stability of the overall photovoltaic floating system. The C-shaped rib plate restricts the position of the mooring cable and prevents the mooring cable from sliding laterally.

[0007] Advantages of this solution: By winding the mooring cables around the outer wall of the truss, the mooring cables and the truss form a surface contact, resulting in a more uniform pressure distribution. This avoids the problem of stress concentration at the through holes in traditional structures, which easily damages the mooring cables and greatly reduces the risk of fatigue damage to the overall structure. This winding connection method allows the wound mooring cables to deform to some extent when the truss is subjected to wind and wave impacts, absorbing the force of the impacts and improving the stability of the overall structure. The winding and fixing method of the mooring cables facilitates inspection and replacement. C-shaped ribs restrict the lateral sliding of the mooring cables, maintaining the connection stability between the mooring cables and the truss, while also facilitating the positioning and installation of the mooring cables.

[0008] Preferably, the system further includes reinforcing ribs for connecting the truss and the C-shaped ribs, and for connecting the ear plates and the C-shaped ribs. The reinforcing ribs further improve the strength of the C-shaped ribs and extend their service life; they also disperse stress, preventing structural stress concentration.

[0009] Preferably, the reinforcing ribs are triangular, forming a triangular structure, which makes the overall structure more stable and has a stronger load-bearing capacity.

[0010] Preferably, the reinforcing ribs are evenly distributed on the truss and ear plates, so that the load borne by the C-shaped ribs is evenly distributed, avoiding stress concentration and extending the service life of the structure.

[0011] Preferably, the truss includes an inner upper chord, an outer upper chord, and a lower chord. The spacing between the inner, outer, and lower chords is equal in each pair. The inner, outer, and lower chords are connected sequentially to form an inverted triangular structure. The ear plate is located on the inner upper chord. Axial limiting plates are provided on both the outer upper and lower chords. Reinforcing ribs are provided between the outer upper chord and the axial limiting plates, and reinforcing ribs are provided between the lower chord and the axial limiting plates. The truss with the triangular structure has stronger overall impact resistance.

[0012] Preferably, the diameters of the inner upper chord, the outer upper chord, and the lower chord are the same.

[0013] Preferably, a U-shaped hole is formed between the outer wall of the inner ring upper chord and the ear plate, with the opening of the hole facing the inner ring upper chord. The U-shaped hole eliminates the need for precise alignment of the mooring cable and the hole, making it easier for the operator to insert the mooring cable and speeding up the installation. The smooth transition of the inner wall of the hole reduces stress concentration on the mooring cable and wear on the inner wall of the hole, extending the service life of the structure.

[0014] Preferably, the size of the U-shaped hole matches the diameter of the mooring line, which provides a better limiting effect on the mooring line.

[0015] Preferably, the ear plate is provided with reinforcing ribs, which are located outside the limiting hole. Stress concentration is prone to occur outside the limiting hole. By providing reinforcing ribs, the rigidity of the limiting hole is increased, and the stress at the limiting hole is dispersed to avoid deformation and failure of the limiting hole.

[0018] Figure 3 This is a schematic diagram of the mooring cable and truss structure in an embodiment of this utility model. Detailed Implementation

[0019] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: inner upper chord 1, outer upper chord 2, lower chord 3, ear plate 4, C-shaped rib 5, reinforcing rib 6, axial limiting plate 7, and mooring cable 8.

[0020] Example: A mooring system connection device, such as Figure 1 , Figure 2 and Figure 3 As shown, it includes a connector and a mooring cable 8. The connector includes a truss and an ear plate 4 disposed on the truss. The truss is provided with a sealed chamber for providing buoyancy. In this embodiment, the sealed chamber is formed by the truss and a skin disposed on the truss, and buoyancy is provided through the skin sealed chamber.

[0021] The truss comprises an inner upper chord 1, an outer upper chord 2, and a lower chord 3. The spacing between the chords in the inner upper chord 1, outer upper chord 2, and lower chord 3 is equal in each pair. These chords are connected sequentially to form an inverted triangular structure. The diameters of the inner upper chord 1, outer upper chord 2, and lower chord 3 are the same. All three chords are hollow to reduce structural weight and save on buoyancy materials. The inner upper chord 1, outer upper chord 2, and lower chord 3 are all constructed from steel tubing.

[0022] Both the upper chord 2 and the lower chord 3 of the outer ring are provided with at least one set of annular axial limiting plates 7. Each set of axial limiting plates 7 consists of two pieces, which are arranged in parallel and perpendicular to the axial direction of the upper chord 2 and the lower chord 3. The inner space of the two axial limiting plates 7 is used to accommodate the mooring rope 8. A reinforcing rib 6 is provided between the outer sides of the upper chord 2 and the axial limiting plates 7, and a reinforcing rib 6 is provided between the outer sides of the lower chord 3 and the axial limiting plates 7. The reinforcing rib 6 is triangular, forming a triangular structure, which makes the overall structure more stable and has a stronger load-bearing capacity. The reinforcing ribs 6 are evenly distributed on the outer sides of the axial limiting plates 7 on the upper chord 2 and the lower chord 3. In this embodiment, the upper chord 2, the axial limiting plates 7, and the reinforcing ribs 6 are fixedly connected by welding.

[0023] Ear plates 4 are fixed to the truss and are located on the inner side of the truss. A hole is provided between the outer wall of the truss and ear plates 4 for the mooring cable 8 to pass through and be wound around. Specifically, ear plates 4 are fixed to the inner upper chord 1, and a hole is provided between the inner upper chord 1 and ear plates 4 for the mooring cable 8 to pass through and be wound around. The mooring cable 8 is passed through the hole formed between the outer wall of the truss and ear plates 4, and then wound around and fixed to the outer wall of the truss. By winding the mooring cable 8 around the outer wall of the truss, the mooring cable 8 and the truss form a surface contact, resulting in a more uniform pressure distribution. This avoids the problem of stress concentration at the through holes in traditional structures, which easily damages the mooring cable 8, and greatly reduces the risk of fatigue damage to the overall structure. The truss structure is used to restrict the movement of the mooring cable 8, maintaining the stability of the overall photovoltaic floating system. The winding connection of the mooring cable 8 allows the wound portion of the mooring cable 8 to deform to a certain extent when the truss is subjected to wind and waves, absorbing the impact force of the wind and waves and improving the stability of the overall structure; the winding and fixing method of the mooring cable 8 makes it easy to inspect and replace.

[0024] In this embodiment, a U-shaped hole is formed between the outer wall of the inner upper chord 1 and the ear plate 4. The opening of the hole faces the inner upper chord 1. The U-shaped hole eliminates the need for precise alignment of the mooring cable 8 with the hole, facilitating the insertion of the mooring cable 8 and speeding up installation. The smooth transition of the hole's inner wall reduces stress concentration on the mooring cable 8 and minimizes wear on the hole's inner wall, extending the structure's service life. The size of the U-shaped hole matches the diameter of the mooring cable 8, providing better positioning of the mooring cable 8.

[0025] In this embodiment, the ear plate 4 is U-shaped, and the opening of the ear plate 4 faces the inner ring upper chord 1.

[0026] The inner ring upper chord 1 is provided with at least two C-shaped ribs 5 arranged opposite each other. The plane of the C-shaped ribs 5 is perpendicular to the axial direction of the inner ring upper chord 1. The upper and lower opening ends of the C-shaped ribs 5 are respectively fixed vertically to the upper and lower surfaces of the ear plate 4. The C-shaped ribs 5 are symmetrically arranged on both sides of the hole. The diameter of the C-shaped ribs 5 matches the diameter of the inner ring upper chord 1. The C-shaped ribs 5 restrict the lateral sliding of the mooring cable 8, maintain the connection stability between the mooring cable 8 and the truss, and facilitate the positioning and installation of the mooring cable 8.

[0027] It also includes reinforcing ribs 6, which connect the truss and the C-shaped ribs 5, and connect the ear plates 4 and the C-shaped ribs 5. By adding reinforcing ribs 6, the strength of the C-shaped ribs 5 is further improved, extending their service life; by dispersing stress, stress concentration problems in the structure are avoided. The reinforcing ribs 6 are evenly distributed on the truss and ear plates 4, ensuring that the load borne by the C-shaped ribs 5 is evenly distributed, avoiding stress concentration and extending the service life of the structure. In this embodiment, the inner ring upper chord 1, ear plates 4, C-shaped ribs 5, and reinforcing ribs 6 are fixedly connected by welding.

[0028] The ear plate 4 is provided with limiting holes, which are used to connect with the longitudinal and transverse cables of the cable net. Specifically, the longitudinal and transverse cables are fixed to the limiting holes of the ear plate 4 by shackles. In this embodiment, the shackles are steel shackles.

[0029] The diameter of the limiting hole matches the diameter of the longitudinal and transverse cables of the cable net, which provides a better limiting effect for the longitudinal and transverse cables.

[0030] The ear plate 4 is provided with reinforcing ribs located outside the limiting hole. Stress concentration is prone to occur on the outside of the limiting hole. By providing reinforcing ribs, the rigidity of the limiting hole is increased, and the stress at the limiting hole is dispersed, preventing deformation and failure of the limiting hole. In this embodiment, the reinforcing ribs are circular steel bars, the length of which is slightly larger than the diameter of the limiting hole. The circular steel bars are fixed to the ear plate 4 by welding.

[0031] The specific implementation process is as follows: The mooring cable 8 is passed through the hole formed between the outer wall of the inner upper chord 1 and the ear plate 4. The mooring cable 8 is then wrapped sequentially around the inner upper chord 1 between the C-shaped ribs 5, the outer upper chord 2 between the axial limiting plates 7, and the lower chord 3 between the axial limiting plates 7. It is then fixed at the U-shaped hole of the ear plate 4 of the inner upper chord 1. Specifically, the mooring cable 8 can be wrapped around the inner upper chord 1, the outer upper chord 2, and the lower chord 3 multiple times and then fixed, depending on actual needs. When the truss is subjected to wind and waves, the mooring cable 8 slightly deforms on the outer wall of the truss to absorb the impact of the wind and waves and maintain the stability of the overall structure. The C-shaped ribs 5 and the axial limiting plates 7 restrict the position of the mooring cable 8 on the inner upper chord 1, the outer upper chord 2, and the lower chord 3 to prevent the mooring cable 8 from sliding laterally.

[0032] In this design, the mooring cable 8 is connected by a winding method. When the truss is subjected to wind and wave impacts, the winding mooring cable 8 can deform to a certain extent, absorbing the impact force of the wind and waves and improving the stability of the overall structure. The winding and fixing method of the mooring cable 8 makes maintenance and replacement easy. By winding the mooring cable 8 around the outer wall of the truss, the mooring cable 8 and the truss form a surface contact, resulting in a more uniform pressure distribution. This avoids the problem of stress concentration at the through holes in traditional structures, which can easily damage the mooring cable 8, and greatly reduces the risk of fatigue damage to the overall structure. The C-shaped rib plate 5 restricts the lateral sliding of the mooring cable 8, maintains the connection stability between the mooring cable 8 and the truss, and facilitates the positioning and installation of the mooring cable 8.
