[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1

[0029] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a maintenance platform, specifically including: a telescopic component 5, the telescopic component 5 including a first telescopic rod 51, a second telescopic rod 52 sleeved outside the first telescopic rod 51, and a fixed rod 53 sleeved outside the second telescopic rod 52; an adjustment component 6 is fixedly provided at one end of the fixed rod 53, and a floating platform 7 is fixedly provided at the end of the adjustment component 6 away from the fixed rod 53.

[0030] Preferably, the floating platform 7 is made of lightweight plastic and has a vacuum inside, allowing it to float on the water surface and possessing a large load-bearing capacity. Workers can stand on the floating platform 7 to inspect and maintain the photovoltaic pillars. The first telescopic rod 51, the second telescopic rod 52, and the fixed rod 53 are all made of rigid materials, ensuring a stable connection for the entire device.

[0031] The telescopic component 5 serves the following purpose: when performing maintenance in a narrow space formed by multiple photovoltaic pillars, the design of connecting the fixed rod 53 to the second telescopic rod 52, and the second telescopic rod 52 to the first telescopic rod 51, allows workers to adaptively adjust the distance between the clamping component 1 and the floating platform 7 within the narrow space, thus adjusting the maintenance position. It also facilitates storage when not in use.

[0032] Furthermore, the first telescopic rod 51 includes a first locking block 511 fixedly disposed at one end of the first telescopic rod 51, two sets of first threaded plates 512 fixedly disposed on the first locking block 511, and a limiting hole 513 opened on the first telescopic rod 51; wherein, the first telescopic rod 51, the second telescopic rod 52, and the fixed rod 53 are all provided with limiting holes 513 of the same size.

[0033] Furthermore, the second telescopic rod 52 includes a second locking block 521, two sets of second threaded plates 522 fixedly disposed on the second locking block 521, a first annular groove 523 opened in the second telescopic rod 52, and two sets of first limiting grooves 524 that cooperate with the two sets of first threaded plates 512; the outer wall of the first locking block 511 cooperates with the inner wall of the first annular groove 523; wherein, two sets of first threaded plates 512 are also fixedly disposed at one end of the second telescopic rod 52 located in the first limiting groove 524, and the two sets of first annular grooves 523 are perpendicular to the two sets of first limiting grooves 524.

[0034] In use, the first telescopic rod 51 is pulled out of the first annular groove 523. Because the outer wall of the first locking block 511 and the inner wall of the first annular groove 523 cooperate with each other and can slide relative to each other, and the second locking block 521 and the second annular groove 531 have the same design, the first telescopic rod 51 and the second telescopic rod 52 can move stably and smoothly in the first annular groove 523 and the second annular groove 531 respectively. When the first telescopic rod 51 moves to the end of the second telescopic rod 52, the first threaded plate 512 on the first telescopic rod 51 passes through the first limiting groove 524 and forms four sets of first threaded plates 512 in a circumferential array with the first threaded plate 512 on the second telescopic rod 52. The included angle between each set of first threaded plates 512 is 90°. Then, the nut is rotated and connected to the four sets of first threaded plates 512. At this time, the connection between the first telescopic rod 51 and the second telescopic rod 52 is stable and firm, and will not be affected by water surface fluctuations, causing the first telescopic rod 51 to retract into the second telescopic rod 52 during maintenance, thereby avoiding the risk of workers falling into the water.

[0035] Furthermore, the fixing rod 53 includes a second annular groove 531 formed within the fixing rod 53, a second limiting groove 532 formed at one end of the fixing rod 53, a mounting base 533 fixedly mounted on the fixing rod 53, a through hole 534 formed on the mounting base 533, a spring 535 fixedly mounted on one side of the mounting base 533, a pin 536 fixedly connected to the other end of the spring 535, a limiting post 537 inserted into the limiting hole 513, and three sets of pin holes 538 evenly distributed on the limiting post 537; the outer wall of the second locking block 521 cooperates with the inner wall of the second annular groove 531; wherein, two sets of second threaded pieces 522 are also fixedly mounted at one end of the fixing rod 53 located in the second limiting groove 532, and the two sets of second threaded pieces 522 are perpendicular to the two sets of second limiting grooves 532.

[0036] The fixing connection between the second telescopic rod 52 and the fixed rod 53 is the same as the connection between the second telescopic rod 52 and the first telescopic rod 51. First, move the second telescopic rod 52 to the end of the fixed rod 53. At this time, the second threaded plate 522 on the second telescopic rod 52 passes through the second limiting groove 532 and forms four sets of second threaded plates 522 arranged in a circular array with the second threaded plate 522 on the fixed rod 53. The included angle between each set of second threaded plates 522 is also 90°. It is best to then rotate the nut onto the four sets of second threaded plates 522. A stable and secure connection is thus formed between the second telescopic rod 52 and the fixed rod 53.

[0037] During maintenance, the overall length of the telescopic assembly 5 needs to be adjusted due to the influence of the water surface environment and the installation position of the photovoltaic pillar, resulting in three possible scenarios. First, the first telescopic rod 51 retracts into the first annular groove 523 within the second telescopic rod 52, and the second telescopic rod 52 retracts into the second annular groove 531 within the fixed rod 53, resulting in the shortest overall length of the telescopic assembly 5. Second, the first telescopic rod 51 extends beyond the second telescopic rod 52, and the second telescopic rod 52 is fixed within the second annular groove 531 of the fixed rod 53, resulting in a moderate overall length of the telescopic assembly 5. Third, the first telescopic rod 51 extends beyond the second telescopic rod 52, and the second telescopic rod 52 extends beyond the fixed rod 53, resulting in the longest overall length of the telescopic assembly 5. In this invention, the three sets of pin holes 538 arranged vertically and equidistantly on the limiting post 537 correspond to the three length scenarios of the telescopic assembly 5.

[0038] When only the shortest overall length of the telescopic assembly 5 is needed, the pin 536 is inserted into the uppermost pin hole 538. At this time, the limiting pin 537 passes through the limiting holes 513 of the fixed rod 53 and the second telescopic rod 52, with the end of the limiting pin 537 inserted into the limiting hole 513 on the first telescopic rod 51, facilitating storage. When the pin 536 is inserted into the middle pin hole 538, the limiting pin 537 passes through the fixed rod 53, with its end inserted into the limiting hole 513 on the second telescopic rod 52. The first telescopic rod 51 can then extend outside the first annular groove 523, and the overall length of the telescopic assembly 5 reaches the appropriate position. When the pin 536 is inserted into the bottom pin hole 538, the end of the limiting pin 537 is inserted into the limiting hole 513 on the fixed rod 53, releasing the limiting of the second telescopic rod 52, and the length of the entire telescopic assembly 5 can be adjusted to its maximum. This design allows workers to adjust the length of the telescopic assembly 5 more conveniently and accurately. The function of spring 535 is to automatically retract pin 536 into pin hole 538, thus simplifying the operation process.

[0039] Furthermore, the adjustment assembly 6 includes a fixed sleeve 61 fixedly connected to one end of the fixed rod 53, a universal joint 62 fixedly disposed at one end of the fixed sleeve 61, and a fixing hole 63 opened on the universal joint 62; the adjustment assembly 6 also includes a U-shaped mounting bracket 64, and a connecting shaft 65 fixedly disposed on the U-shaped mounting bracket 64; the U-shaped mounting bracket 64 also has a plurality of fixed holes 63 arranged in an array; wherein, the universal joint 62 is rotatably connected to the connecting shaft 65; the end of the U-shaped mounting bracket 64 away from the universal joint 62 is fixedly connected to the floating platform 7.

[0040] like Figure 1 As shown, the fixed shaft 53 and the adjustment assembly 6 are positioned close to the floating platform. The advantage of this design is that it shortens the distance between the adjustment position and the operator, making it easier for the operator to adjust by hand during maintenance.

[0041] It should be noted that the adjustment component 6 facilitates maintenance in confined spaces. Due to the installation location of the photovoltaic support in water and the limitations imposed by the water surface environment, workers sometimes need to adjust the angle of the telescopic component 5 to better secure the device. Therefore, by creating fixing holes 63 on the universal joint 62 and also creating a circular array of fixing holes 63 on the U-shaped mounting bracket 64, when angle adjustment is needed, simply align the corresponding fixing holes 63 on the U-shaped mounting bracket 64 with the fixing holes 63 on the universal joint 62, and finally secure with bolts to achieve angle adjustment between the fixing rod 53 and the floating platform 7. The fixing holes 63 on the U-shaped mounting bracket 64 correspond to different fixing angles of the clamping component 1 and the maintenance angle of the floating platform 7.

[0042] In summary, the three-stage structure of the telescopic assembly—the first telescopic rod, the second telescopic rod, and the fixed rod—allows for flexible adjustment of the distance between the clamping assembly and the floating platform within the narrow space of the photovoltaic support, adapting to different maintenance positions. When not in use, retracting the telescopic assembly can reduce the storage volume and lower storage and transportation costs. Furthermore, the structural design of the limiting post and pin post with three sets of pin holes allows the telescopic assembly to quickly switch between three lengths, improving adjustment efficiency and adapting to different water surface environments.

[0043] Example 2

[0044] Reference Figures 1-2 The second embodiment of this utility model further includes: a clamping component 1, a movable block 2 axially connected to the clamping component 1, a rotating component 3 screwed into the movable block 2, and a support frame 4 externally connected to the rotating component 3; the support frame 4 is axially connected to the clamping component 1; the clamping component 1 is provided in two sets, and the two sets of clamping components 1 are symmetrically arranged on both sides of the movable block 2.

[0045] Furthermore, the clamping assembly 1 includes a clamp 11, an L-shaped frame 12 movably connected within the clamp 11, and two sets of first annular frames 13 movably connected to the clamp 11; wherein one side of the clamp 11 is configured as an arc shape.

[0046] Preferably, the clamp 11 has teeth at the arc-shaped part, which are used to increase the friction between the clamp 11 and the photovoltaic support, thereby achieving a stable clamping.

[0047] Furthermore, a threaded hole 21 is provided in the middle of the movable block 2, and two sets of second annular frames 22 are symmetrically arranged at both ends of the movable block 2, and the end of the second annular frame 22 away from the movable block 2 is movably connected to the L-shaped frame 12.

[0048] Furthermore, the rotating assembly 3 includes a screw 31 and a handle 32 that rotates coaxially with the screw 31; wherein the screw 31 is connected to the moving block 2 through a threaded hole 21.

[0049] Rotating the screw 31 allows the movable block 2 to move along it, thereby driving the clamp 11 to hold the photovoltaic bracket, providing both convenient operation and stable clamping. The function of the first ring frame 13 is to provide stable support between the clamp 11 and the support frame 4 during the rotation of the clamp 11. When the clamp 11 rotates, the first ring frame 13 rotates around the support frame 4. The other end of the first ring frame 13 is axially connected to the clamp 11. Therefore, during the rotation of the clamp 11, the first ring frame 13 ensures that the rotation trajectory of the clamp 11 is on a horizontal plane.

[0050] Furthermore, the screw 31 is rotatably connected to the support frame 4; the end of the first annular frame 13 away from the clamp 11 is axially connected to the support frame 4, and the corner of the L-shaped frame 12 is also axially connected to the support frame 4.

[0051] In use, rotating the handle 32 causes the screw 31 to rotate coaxially with the handle 32, thus moving the moving block 2 closer to the handle 32. The moving block 2 then moves the second annular frame 22. Under the action of the second annular frame 22, the L-shaped frame 12 rotates using the connection point between the support frame 4 and the inflection point of the L-shaped frame 12 as its rotation point. The clamp 11, driven by the L-shaped frame 12, moves closer to the central axis of the screw 31. Because the clamping assembly 1 has two sets, both sets of clamps 11, driven by the two sets of L-shaped frames 12 respectively, move closer to the central axis of the screw 31 to clamp the photovoltaic support, facilitating subsequent maintenance of the photovoltaic support pillar.

[0052] It should be noted that, as Figure 2 As shown, the two sets of clamps 11 are in the open state in the initial state. The moving block 2 is located at the end of the screw 31 that is furthest from the handle 32. When the screw 31 is rotated to move the moving block 2 toward the handle 32, the two sets of clamps 11 gradually retract toward the center.

[0053] In summary, the structural design that uses the rotating handle to move the screw and thus bring the two sets of clamps closer to the central axis of the screw not only achieves stable clamping of the photovoltaic bracket, but also allows the clamping components to flexibly adapt to photovoltaic brackets of different sizes, improving the versatility and applicability of the fixing mechanism.

[0054] The rest of the structure is the same as in the above embodiments.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
