Description

Technical Field

[0001] This utility model relates to the field of construction technology for offshore photovoltaic grid support systems, specifically a reverse-hanging connection structure. Background Technology

[0002] Offshore photovoltaic (PV) grid-type support structures are specifically designed for offshore PV projects. They support the PV modules, ensuring their stable operation in harsh marine environments. The support system uses a grid structure, with multiple interconnected grid units forming a stable support network. This structure effectively distributes external forces, improving the overall stability of the support system. The support system is typically made of high-strength steel or other corrosion-resistant materials to ensure it can withstand the impacts of wind and waves in harsh marine environments. To adapt to different sunlight conditions and sea conditions, the tilt angle of the support system can be adjusted. This helps maximize the utilization of solar radiation and improve power generation efficiency.

[0003] The existing construction platforms used for the erection of offshore photovoltaic grid supports still have certain shortcomings: the existing construction platforms are inconvenient to carry, cumbersome to assemble, and difficult to flexibly adjust the height under the support with dense lower chord members, which increases construction difficulties and reduces construction efficiency. Based on the shortcomings of the existing technology, this utility model designs a reverse hanging connection structure. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a reverse-hanging connection structure, which has the advantage of facilitating flexible adjustment of the construction height under a support structure with dense lower chord members.

[0005] This utility model provides the following technical solution: a reverse-hanging connection structure, including four main support rods, with a rotating handle rotatably mounted at one bottom end of each of the four main support rods, internal threaded grooves formed inside the four rotating handles, a limit rod fixedly mounted on one side of the inner wall of each of the main support rods, and a lifting structure provided inside each of the four main support rods; the four lifting structures include secondary support rods, with a hook at one end of each secondary support rod, external threaded grooves formed on the outer surface of each of the four secondary support rods, and limit grooves formed inside each of the four secondary support rods.

[0006] As a preferred embodiment of this utility model, two horizontal plates are placed inside the four hooks, and two slots are formed inside the two horizontal plates.

[0007] As a preferred technical solution of this utility model, the two sets of slots are internally connected to vertical plates, and the two ends of the two vertical plates can be spliced ​​together.

[0008] As a preferred embodiment of this utility model, the top of the four main support rods is provided with a locking structure, and the four locking structures include two curved rail plates.

[0009] As a preferred embodiment of this utility model, the two curved rail plates are fixedly connected to the main support rod, and curved plates are slidably connected inside the two curved rail plates.

[0010] As a preferred embodiment of this utility model, a clamping plate is fixedly installed on one side of the outer surface of the two curved plates, and clamping blocks are installed on both sides of the two clamping plates.

[0011] As a preferred embodiment of this utility model, two protruding blocks are installed on one side of the outer surface of the two curved rail plates, and fixing grooves are formed inside the two protruding blocks.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This reverse-hanging connection structure, through the main support rods and lifting structure, allows the assembly device to be assembled by hanging the top bends of the four main support rods on the chords below the bracket, supporting the two horizontal plates by hanging them on the hooks, and then locking the two vertical plates in the slots for worker movement. By rotating the four rotating handles, since the limiting slots are locked in the limiting rods, the auxiliary support rods move up and down horizontally inside the main support rods when the rotating handles are rotated. This allows the four auxiliary support rods to drive the slots and vertical plates to flexibly adjust the construction height below the bracket, reducing construction difficulty and improving construction efficiency.

[0014] 2. This reverse-hanging connection structure, through a locking mechanism, after the four main support rods are hung on the chord below the bracket, push the four bent plates respectively to move them out of the curved rail plate. At this time, the bent plates and the curved rail plate form an approximately circular clamp around the chord. By fixing the clamping blocks in the fixing groove, the four main support rods can be locked on the chord to prevent the main support rods from falling off during construction and to protect the safety of construction personnel.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 A reverse-hanging connection structure includes four main support rods 1. A rotating handle 101 is rotatably installed at one bottom end of each of the four main support rods 1. The interior of each rotating handle 101 has an internal threaded groove 102. A limit rod 103 is fixedly installed on one side of the inner wall of each main support rod 1. A lifting structure 2 is provided inside each of the four main support rods 1. Each lifting structure 2 includes a secondary support rod 21. One end of each secondary support rod 21 has a hook 22. The outer surface of each secondary support rod 21 has an external threaded groove 23. A limit groove 24 is provided inside each secondary support rod 21.

[0024] Please see Figure 1 and Figure 6 Inside the four hooks 22, there are two horizontal plates 4, and inside the two horizontal plates 4, there are two slots 5. The two slots 5 are fitted with vertical plates 6, and the two ends of the two vertical plates 6 can be spliced ​​together.

[0025] Two horizontal plates 4 are hung at the hook 22 for support, and then two vertical plates 6 are inserted into the slots 5 for workers to walk on. The two ends of the two vertical plates 6 can be spliced ​​with other vertical plates 6, making it easier for construction workers to move under the support.

[0026] Please see Figure 5 The top of each of the four main support rods 1 is equipped with a locking structure 3, which includes two curved rail plates 31. The two curved rail plates 31 are fixedly connected to the main support rods 1, and curved plates 34 are slidably connected inside the two curved rail plates 31. A clamping plate 35 is fixedly installed on one side of the outer surface of each of the two curved plates 34, and clamping blocks 36 are installed on both sides of the two clamping plates 35. Two protruding blocks 32 are installed on one side of the outer surface of each of the two curved rail plates 31, and fixing grooves 33 are formed inside the two protruding blocks 32.

[0027] After the four main support rods 1 are hung on the chord below the bracket, the four bent plates 34 are pushed to move them out of the bent rail plate 31. At this time, the bent plates 34 and the bent rail plate 31 form an approximately circular clamp around the chord. By fixing the clamping block 36 in the fixing groove 33, the four main support rods 1 can be locked on the chord to prevent the main support rods 1 from falling off during construction and to protect the safety of the construction personnel.

[0028] The working principle is as follows: When using a reverse-hanging connection structure, the top bends of the four main support rods 1 are first hung on the chord below the bracket. Two horizontal plates 4 are hung at the hooks 22 for support. Then, two vertical plates 6 are inserted into the slots 5 for workers to walk on. Subsequently, by rotating the four rotating handles 101, since the limiting grooves 24 are inserted into the limiting rods 103, the auxiliary support rods 21 move up and down horizontally inside the main support rods 1 when the rotating handles 101 are rotated. This allows the four auxiliary support rods 21 to drive the slots 5 and the vertical plates 6 to flexibly adjust the construction height below the bracket. After the four main support rods 1 are hung on the chord below the bracket, the four bent plates 34 are pushed to move them out of the curved rail plates 31. At this time, the bent plates 34 and the curved rail plates 31 form an approximately circular clamp around the chord. By locking the locking blocks 36 into the fixing grooves 33, the four main support rods 1 can be locked onto the chord to prevent the main support rods 1 from falling off during construction and to protect the safety of the construction personnel.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
