[0002] Currently, during the installation of floating photovoltaic systems, the anti-corrosion treatment of pile heads, supports, purlins, components, as well as cable trays and cables, all need to be carried out using floating work platforms, and each task has high requirements for construction precision.

[0003] Compared to land-based construction, the stability of floating platforms on water is particularly important. For example, the CN221477480U floating photovoltaic power generation installation platform includes a platform component and a moving component. Multiple sets of the moving component are arranged along the bottom corners of the platform component. The platform component includes a hollow floating platform, a circular sleeve, an internally threaded hole, and mounting lugs. The moving component includes an externally threaded cylinder, a support column, a first vacuum tube, a second vacuum tube, and an internal hexagonal groove. The externally threaded cylinder is threaded into the circular sleeve, and the internal hexagonal groove is located at the top of the externally threaded cylinder. During photovoltaic installation, the lack of stability of this patented platform leads to low operator efficiency and safety risks. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for a floating photovoltaic installation platform, which solves the problems of low work efficiency and safety caused by the inability of the existing technology to fully stabilize the working platform.

[0005] This utility model is implemented as follows: a fixing device for a floating photovoltaic installation platform includes: an inner sleeve and an outer sleeve sleeved on the inner sleeve. The inner sleeve has a first pin hole, and the outer sleeve has a second pin hole corresponding to the first pin hole. The first end of the inner sleeve has a bayonet fixing structure, and a directional rotation structure is provided between the bayonet fixing structure and the outer sleeve. The directional rotation structure is fixed to the inner sleeve.

[0006] This utility model uses a rotating structure to adjust the direction of the clamping mechanism to be horizontal, thus clamping the pile body. At this time, the positions of the first pin hole and the second pin hole of this device coincide, and the matching pin passes through the first pin hole and the second pin hole simultaneously to achieve turning and fixing. At this time, the floating platform achieves stability by clamping the pile body, thereby further ensuring construction safety, improving construction efficiency, and achieving high-quality and high-efficiency construction.

[0007] A further technical solution of this utility model is: an end plate is provided on the second end of the inner sleeve, and the projection of the end plate along the axial direction of the inner sleeve at least partially overlaps with the outer sleeve.

[0008] The end plate is welded and fixed to the inner sleeve to prevent the inner sleeve from coming out of the outer sleeve.

[0009] A further technical solution of this utility model is that the length of the inner sleeve is greater than the length of the outer sleeve, and the inner sleeve and the outer sleeve can move relative to each other in the axial direction.

[0010] The inner sleeve is longer than the outer sleeve to ensure sufficient space for installing the bayonet fixing structure and the directional rotation structure.

[0011] A further technical solution of this utility model is: the directional rotation structure includes an inner ring, an outer ring, and a support rod, the inner ring is coaxially connected to the inner sleeve, and the outer ring is concentric with the inner ring and connected through the support rod.

[0012] The inner sleeve can be rotated more conveniently and stably through the construction of the inner ring, outer ring, and support rod.

[0013] A further technical solution of this utility model is: multiple support rods are arranged at intervals along the circumference of the inner ring between the inner ring and the outer ring.

[0014] Multiple support rods further ensure stability.

[0015] A further technical solution of this utility model is: the directional rotation structure includes multiple grips, one end of each grip is connected to the inner sleeve, and the multiple grips are spaced apart circumferentially on the inner sleeve.

[0016] The grip structure is simpler and easier to manufacture.

[0017] A further technical solution of this utility model is: the bayonet fixing structure includes a straight rod, one end of which is perpendicularly connected to the inner sleeve, and two straight rods are spaced apart along the axial direction of the inner sleeve to form a limiting bayonet, which is sleeved on the outer structure.

[0018] The straight bar is simple and stable to set up, and can firmly hold the main pile body to achieve stability.

[0019] A further technical solution of this utility model is: the limiting slot is configured in a U-shape, and the external structure includes a pile body for supporting photovoltaic modules; the inner width of the limiting slot is greater than the outer diameter of the pile body.

[0020] The U-shaped locking jaws are better suited to the pile body, making it more convenient to lock the pile body in place.

[0021] A further technical solution of this utility model is: the bayonet fixing structure also includes a diagonal rod; one end of the diagonal rod is fixed to the side of the straight rod, and the other end of the diagonal rod is fixed to the inner sleeve, and the diagonal rod and the straight rod are arranged in a one-to-one correspondence.

[0022] The diagonal brace further ensures the stability of the bayonet fixing structure.

[0023] A further technical solution of this utility model is that both the straight rod and the diagonal rod are configured as square steel tubes.

[0024] Square steel pipes are lightweight yet sturdy, ensuring stability without becoming bulky.

[0025] The beneficial effects of this utility model are as follows: By rotating the structure, the direction of the clamping mechanism is adjusted to be horizontal; the pile body is clamped, and at this time the positions of the first pin hole and the second pin hole of this device coincide. The matching pin passes through the first pin hole and the second pin hole at the same time to achieve turning and fixing; at this time, the floating platform achieves stability by clamping the pile body, thereby further ensuring construction safety, improving construction efficiency, and achieving high-quality and high-efficiency construction.

[0036] Example 1: Figure 1 The overall structure of this utility model is shown, including an outer sleeve 1, an inner sleeve 2, a directional rotation structure 3, and a bayonet fixing structure 4. The main body is the outer sleeve 1 and the inner sleeve 2. The length of the inner sleeve 2 is greater than the length of the outer sleeve 1, which can ensure that there is enough space to install the directional rotation structure 3 and the bayonet fixing structure 4. The inner sleeve 2 is inserted into the outer sleeve 1, and the inner sleeve 2 and the outer sleeve 1 can move relative to each other in the axial direction. This can ensure smoother adjustment of the direction of the bayonet fixing structure 4.

[0037] The first ends of the outer sleeve 1 and the inner sleeve 2 are nearly flush. An end plate 22 is welded on the inner sleeve 2. The end plate can be round, square or rectangular. The length or area of ​​the end plate 22 needs to be greater than the diameter or cross-sectional area of ​​the outer sleeve 1, so as to prevent the inner sleeve 2 from falling out of the outer sleeve 1.

[0038] The directional rotation structure 3 is fixed to the inner sleeve 2. The position of this device is close to the second end of the outer sleeve 1. It has the same function as the end plate 22 and can also prevent the inner sleeve 2 from falling off the outer sleeve 1. The directional rotation structure 3 also serves to rotate the inner sleeve 2 to adjust the direction of the bayonet fixing structure 4.

[0039] The clamping structure 4 is fixed to the second end of the inner sleeve 2. Its size is adapted to the pile body to be clamped. The inner sleeve 2 is rotated by the direction rotation structure 3, thereby adjusting the clamping direction of the clamping structure 4 to clamp the pile body.

[0040] As shown Figure 2 This is a structural diagram of the outer sleeve 1. A steel pipe with an outer diameter of Φ60mm and a wall thickness of 3.5mm can be used, with a length of 1.2m. The second pin hole 11 is a Φ14 round hole.

[0041] Figure 3 This is a structural diagram of the inner sleeve 2. It can be made of steel pipe with an outer diameter matching the inner diameter of the outer sleeve 1 and a wall thickness of 3.5mm. The length is 1.2m + 0.1m + 0.4m = 1.7m. The first pin hole 21 is a Φ14 round hole, and the end plate 22 is a steel plate with a diameter of 80mm and a thickness of 5mm.

[0042] Both the inner sleeve 2 and the outer sleeve 1 are made of steel, which can ensure the robustness of the device. When the first pin hole 21 and the second pin hole 11 are rotated to the same position, a matching pin is inserted to fix the position of the inner sleeve 2 and the outer sleeve 1.

[0043] Figure 4 The inner sleeve 2 of this utility model passes through the direction rotation structure 3 and is welded and fixed to the direction rotation structure 3. At the same time, the direction rotation structure 3 also serves to prevent the inner sleeve 2 from coming out of the outer sleeve 1.

[0044] The directional rotation structure 3 includes: an inner ring 31, an outer ring 32, and support rods 33. The inner ring 31 and the outer ring 32 are coaxial. Multiple support rods 33 are provided between the inner ring 31 and the outer ring 32. The multiple support rods 33 are arranged at intervals along the circumference of the inner ring 31 between the inner ring 31 and the outer ring 32.

[0045] The inner sleeve 2 passes through the inner ring 31, and the inner ring 31 is fixed on the inner sleeve 2. When the outer ring 32 is rotated, the inner sleeve 2 can be rotated, thereby achieving the effect of adjusting the direction of the bayonet. The design of the inner ring 31, the outer ring 32 and the support rod 33 makes it easier and more convenient for the operator to rotate, and it is also more stable and reliable when rotating.

[0046] Figure 5 The bayonet fixing structure 4 uses a 40mm*40mm square steel pipe, which is welded and fixed to the inner sleeve 2. L1 represents the inner width of the limiting bayonet, and L2 represents the distance from the welding point of the inclined rod 42 on the straight rod 41 to the top of the straight rod 41. L1 = pile diameter + 20mm and L2 = pile radius + 20mm can achieve the fixing function.

[0047] The bayonet fixing structure 4 includes a straight rod 41, one end of which is perpendicularly connected to the inner sleeve 2. Two straight rods are spaced apart along the axial direction of the inner sleeve to form a limiting bayonet, which is sleeved on the outer structure.

[0048] The straight bar is simple and stable to set up, and can firmly hold the pile body to achieve stability;

[0049] The limiting bayonet is U-shaped, and the external structure includes a pile body for supporting photovoltaic modules; the inner width of the limiting bayonet is greater than the outer diameter of the pile body.

[0050] The U-shaped limiting jaw is more suitable for the pile body, making it more convenient to clamp the pile body. The shape of the limiting jaw can also be adjusted according to the different shapes of the pile body to ensure that the clamp fixing structure 4 can clamp the pile body and ensure stability.

[0051] The bayonet fixing structure 4 also includes a diagonal rod 42; one end of the diagonal rod 42 is fixed to the side of the straight rod, and the other end of the diagonal rod 42 is fixed to the inner sleeve 2. The diagonal rod 42 and the straight rod 41 are arranged in a one-to-one correspondence.

[0052] The straight rod 41 is further secured by the diagonal rod 42 to prevent the straight rod 41 from loosening during photovoltaic installation, which could lead to unstable clamping and affect operation. Both the straight rod 41 and the diagonal rod 42 are made of square steel pipe, ensuring their sturdiness.

[0053] Figure 6 This is a schematic diagram of the utility model installed below the deck of a floating work platform. The deck has a pre-drilled hole 5 to facilitate the subsequent insertion of pins for fixation. In the initial state, the locking mechanism 4 faces downward. The locking mechanism 4 can be adjusted by rotating the direction mechanism 3 to lock the pile body.

[0054] Figure 7 This is a schematic diagram of the utility model, which uses a bayonet to hold the pile body in place. The bayonet fixing structure 4 holds the pile body in place, thereby achieving the effect of stabilizing the floating platform.

[0055] Working principle:

[0056] 1. This utility model is installed below the deck of a floating platform and fixed to the transverse main keel by welding or using matching fasteners. A 200mm*200mm pre-drilled opening is made at the position corresponding to the second pin hole 11 on the deck. At this time, the snap-fit ​​structure 4 of this utility model faces downwards. Figure 6 .

[0057] 2. When the floating platform reaches the work surface, rotate the direction rotation structure 3 of this utility model to adjust the direction of the locking structure 4 of this utility model to be horizontal. At this time, the second pin hole 11 and the first pin hole 21 of this utility model are aligned. The matching pin passes through the second pin hole 11 and the first pin hole 12 at the same time to achieve steering and fixation. At this time, the floating platform achieves stability by locking the pile body.

[0058] Example 2: The directional rotation structure 3 includes multiple handles, one end of each handle is connected to the inner sleeve 2, and the multiple handles are spaced apart circumferentially on the inner sleeve 2.

[0059] The grip structure is simpler and easier to manufacture.
