Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic construction technology, specifically a positioning frame for marine photovoltaic pile foundations. Background Technology

[0002] Offshore photovoltaic (PV) systems are photovoltaic power generation systems built in intertidal zones, nearshore areas, and deep-sea areas. They can avoid land restrictions on land, are close to coastal load centers, and have a power generation efficiency that is 5%-10% higher than that of onshore systems. They are widely used in coastal energy bases.

[0003] Currently, operators frequently need to use pile positioning frames when constructing offshore photovoltaic systems. While existing pile positioning frames have basic pile positioning functions, there is still room for improvement. During the truss installation phase, the frames need to be hoisted to the work area by crane, where operators grab and assemble them on-site. Complex natural factors such as wind, waves, and currents at sea can cause irregular swaying and attitude deviations of the truss during hoisting. The sway amplitude can easily increase with environmental changes, making it difficult for operators to aim steadily and grab the truss accurately. This not only prolongs the time required for each grab but also significantly increases the difficulty of high-altitude operations and the risk of collisions, adversely affecting construction progress and operational safety. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this invention is to address the above-mentioned problems. This invention provides a positioning frame for marine photovoltaic pile foundations, which has the advantages of reducing operational difficulty and risk.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning frame for marine photovoltaic pile foundations, comprising a left platform, a rectangular block fixedly installed on the right side of the top of the left platform, a connecting block fixedly connected to the top of the rectangular block, a long rod movably connected to the top of the connecting block, a material box fixedly installed at the top of the long rod, a servo motor fixedly installed below the left side of the connecting block, a rotating shaft fixedly sleeved at the other end of the output shaft of the servo motor, a moving rod fixedly sleeved on the outer surface of the rotating shaft, a movable rod hinged to the other end of the moving rod, and the other end of the movable rod hinged to the left side of the long rod.

[0006] As a preferred embodiment of this utility model, the top end of the connecting block is fixedly connected to a limiting rod located inside the long rod, and the outer surface of the limiting rod is movably connected to the interior of the long rod.

[0007] As a preferred embodiment of this utility model, a right platform is movably connected to the right side of the left platform, an installation plate is fixedly installed on the left side of the top of the right platform, and a floating box is fixedly connected to the bottom of both the left and right platforms.

[0008] As a preferred embodiment of this invention, an assembly frame is fixedly connected to the top of the mounting plate, and a counterweight is movably connected inside the assembly frame.

[0009] As a preferred embodiment of this utility model, positioning blocks are fixedly connected to the two corners of the left side of the left platform in the front-back direction and the two corners of the right side of the right platform in the front-back direction. There are four positioning blocks, and the four positioning blocks are of the same size.

[0010] As a preferred embodiment of this invention, a guide block located inside the left platform is fixedly connected to the left side of the right platform, and the outer surface of the guide block is movably connected to the interior of the left platform.

[0011] As a preferred embodiment of this utility model, a circular block is fixedly connected to the left side of the front of the left platform, and a short shaft is movably mounted on the outer surface of the circular block. The back of the short shaft is movably connected to the front of the guide block.

[0012] As a preferred embodiment of the present invention, the guide block is internally threaded with a threaded shaft, the front side of the threaded shaft passing through the guide block and the short shaft in sequence and extending to the outside of the front side of the short shaft, and the outer surface is movably connected to the inside of the short shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting up a material loading box, a servo motor, a rotating shaft, a moving rod, and a movable rod, allows the operator to start the servo motor, which will cause the rotating shaft and the moving rod to rotate. This will cause the movable rod to push the long rod and the material loading box upward, thereby enabling the material loading box to move to the material loading point. This operation avoids the problem that when operators use a hoisting machine to hoist the truss, the truss may sway due to natural environmental factors such as wind and waves, making it difficult for operators to accurately grasp the truss.

[0015] 2. This utility model, by setting up a circular block, a short shaft, and a threaded shaft, allows the operator to rotate the threaded shaft, causing its back side to detach from the inside of the guide block, thereby releasing the fixing effect on the guide block. Subsequently, the operator rotates the short shaft, causing its back side to detach from the front of the guide block, thus releasing the pre-fixing effect on the guide block. Then, the operator pulls the right platform, causing the mounting plate to detach from the inside of the left platform, thereby completing the modular disassembly operation and facilitating the subsequent transportation of the left platform and rectangular block by the operator.

[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] like Figures 1 to 5 As shown, this utility model provides a positioning frame for offshore photovoltaic pile foundations, including a left platform 1. A rectangular block 2 is fixedly installed on the right side of the top of the left platform 1. A connecting block 3 is fixedly connected to the top of the rectangular block 2. A long rod 4 is movably connected to the top of the connecting block 3. A material box 5 is fixedly installed on the top of the long rod 4. A servo motor 6 is fixedly installed on the lower left side of the connecting block 3. A rotating shaft 7 is fixedly sleeved at the other end of the output shaft of the servo motor 6. A moving rod 8 is fixedly sleeved on the outer surface of the rotating shaft 7. A movable rod 9 is hinged to the other end of the moving rod 8. The other end of the movable rod 9 is hinged to the left side of the long rod 4.

[0024] When the operator starts the servo motor 6, the rotating shaft 7 and the moving rod 8 will rotate, which will cause the moving rod 9 to push the long rod 4 and the material box 5 upward, so that the material box 5 can reach the position for loading materials. Since the rectangular block 2 is fixed to the top of the left platform 1 by bolts, the rectangular block 2 can be removed.

[0025] The top of the connecting block 3 is fixedly connected to a limiting rod 10 located inside the long rod 4, and the outer surface of the limiting rod 10 is movably connected to the inside of the long rod 4.

[0026] Due to the design of the limiting rod 10, it can effectively guide the movement of the long rod 4.

[0027] The right side of the left platform 1 is movably connected to the right platform 11, and the left side of the top of the right platform 11 is fixedly installed with an installation plate 12. The bottom ends of both the left platform 1 and the right platform 11 are fixedly connected with floating boxes 20.

[0028] Since the mounting plate 12 is fixed to the top of the right platform 11 by bolts, the mounting plate 12 can be removed later.

[0029] The top of the mounting plate 12 is fixedly connected to the assembly frame 13, and the interior of the assembly frame 13 is movably connected to the counterweight block 14.

[0030] Due to the design of the counterweight 14, the loading box 5 can be prevented from tilting severely due to gravity when it is loaded with too much material.

[0031] Positioning blocks 15 are fixedly connected to the two corners of the left side of the left platform 1 in the front-back direction and the two corners of the right side of the right platform 11 in the front-back direction. There are four positioning blocks 15, and the four positioning blocks 15 are the same size.

[0032] The design of the four positioning blocks 15 allows operators to insert the pile foundation into the four positioning blocks 15 for pile driving operations.

[0033] The left side of the right platform 11 is fixedly connected to a guide block 16 located inside the left platform 1, and the outer surface of the guide block 16 is movably connected to the interior of the left platform 1.

[0034] Due to the design of the guide block 16, the movement of the right platform 11 can be effectively limited.

[0035] Among them, a circular block 17 is fixedly connected to the left side of the front of the left platform 1, and a short shaft 18 is movably installed on the outer surface of the circular block 17. The back of the short shaft 18 is movably connected to the front of the guide block 16.

[0036] When the short axis 18 is located on the front of the guide block 16, it will have a pre-fixing effect on the guide block 16.

[0037] The guide block 16 has a threaded shaft 19 inside it. The front of the threaded shaft 19 passes through the guide block 16 and the short shaft 18 in sequence and extends to the outside of the front of the short shaft 18, and its outer surface is movably connected to the inside of the short shaft 18.

[0038] When one end of the threaded shaft 19 is inside the guide block 16, it will have a fixing effect on the guide block 16.

[0039] Working principle and usage process of this utility model:

[0040] The operators first insert the pile foundation into the four positioning blocks 15 to complete the precise positioning and driving of the pile foundation. Then, they proceed to the truss installation stage. The servo motor 6 is started, and the servo motor 6 drives the rotating shaft 7 and the moving rod 8 to rotate synchronously. The moving rod 9 pushes the long rod 4 and the loading box 5 upward until the loading box 5 reaches the designated height for truss installation. When loading truss components into the loading box 5, the operators need to place counterweights 14 of corresponding weight into the assembly frame 13 according to the weight of the components to ensure the gravity balance at the top of the left platform 1 and the right platform 11, and avoid the platform swaying due to the shift of the center of gravity. This design replaces the traditional hoisting method and effectively prevents the truss components from swaying during the hoisting process, ensuring the safety and stability of the offshore operation.

[0041] After the offshore photovoltaic installation is completed, the left platform 1 and the right platform 11 need to be disassembled for easy transportation. The operator first rotates the threaded shaft 19 so that its back side is disengaged from the threaded hole of the guide block 16, thereby releasing the fixed limit on the guide block 16. Then, the short shaft 18 is rotated so that its back side is separated from the front side of the guide block 16, completely releasing the lock. At this time, the operator can pull the right platform 11 forward to drive the guide block 16 out of the installation slot of the left platform 1, completing the disassembly of the left platform 1 and the right platform 11. The disassembled platform is smaller in size and easier to transport, which greatly reduces the difficulty and cost of offshore transportation.
