[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application: Specific embodiment 1:

[0037] refer to Figure 1 to Figure 2 As shown, a pile-based photovoltaic assembly of the utility model includes a pile foundation 1 and an upper bracket 11 fixedly arranged at the upper end of the pile foundation 1, a photovoltaic panel (not shown in the figure) is arranged on the upper bracket 11, and also includes a liftable construction platform of the pile-based photovoltaic assembly (hereinafter referred to as the liftable construction platform). The lower end of the pile foundation 1 extends into and is fixed to the seabed H, and the upper end of the pile foundation 1 extends out of the sea level S. During actual operation, the upper bracket 11 is first seated on the pile top A of the pile foundation 1, and then the staff completes the fixation through the liftable construction platform of the pile-based photovoltaic assembly.

[0038] Specifically, Figure 1 , 2 As shown, the liftable construction platform includes a mounting frame, which is fixed to the upper part of the pile foundation 1 through a fixed structure, and a construction platform 6 is arranged on the upper part of the mounting frame. A lifting device is arranged on the construction platform 6, and the lifting device includes a lifting platform 12 and a lifting mechanism. The lifting mechanism includes a scissor frame structure 9 and a driving mechanism arranged between the lifting platform 12 and the construction platform 6. The upper end of the scissor frame structure 9 is extended in the horizontal direction (i.e. Figure 1Two upper hinged ends are arranged at intervals in the length direction of the lifting platform 12 shown in the figure, and both upper hinged ends are hinged to the lower bottom surface of the lifting platform 12. Two lower hinged ends are arranged at intervals in the horizontal direction at the lower end of the scissors frame structure 9, and both lower hinged ends are hinged to the upper end surface of the construction platform 6.

[0039] In this way, by fixing the mounting frame on the pile foundation 1 and utilizing the fixity of the pile foundation 1 to provide stable support for the liftable construction platform, the liftable construction platform will not be affected by wind and waves and will not sway back and forth during actual work, thereby ensuring the safety of workers working on it. The lifting platform 12 can be lifted up and down in the vertical direction using the lifting mechanism, so that the workers can rise to a predetermined height with the lifting platform 12, thereby facilitating the fixing of the upper bracket 11 and the pile foundation 1. The scissor frame structure 9 can ensure the stability of the lifting platform 12 during the lifting process, thereby ensuring construction safety, and can realize flexible and adjustable height of the lifting platform 12, which can adapt to construction requirements at different heights, and is conducive to more convenient construction of the pile top A and the upper bracket 11. At the same time, in actual use, the liftable construction platform can be used to facilitate the inspection and maintenance of photovoltaic modules.

[0040] Among them, the mounting frame includes a mounting column 4, which is arranged parallel to one side of the pile foundation 1, and the fixing structure includes a fixing ear 3 and a clamp 2, wherein the fixing ear 3 is arranged at a position corresponding to the lower end of the mounting column 4 of the pile foundation 1, the lower end of the mounting column 4 is connected to the fixing ear 3, and the peripheral surface of the mounting column 4 is fixed to the pile foundation 1 through the clamp 2. In this embodiment, three clamps 2 are arranged at intervals along the vertical direction, and the uppermost clamp 2 is arranged close to the top of the mounting column 4, and the lifting platform 12 is arranged between the uppermost clamp 2 and the middle clamp 2. Of course, in other embodiments, when the actual fixing requirements are met, the number of clamps 2 can be set according to actual needs, such as 1, 2, 4, etc. In this way, the fixing ear 3 can provide support for the lower end of the mounting column 4 on the one hand, and the vertical position of the mounting column 4 can be limited on the other hand. The clamp 2 can fix the peripheral surface of the mounting column 4 on the pile foundation 1, ensuring that the mounting column 4 is reliably fixed on the pile foundation 1.

[0041] Preferably, in this embodiment, Figure 1 As shown, the lower end of the installation column 4 is hingedly connected to the fixed lifting ear 3, which can reduce the actual installation difficulty and facilitate the adjustment of the position between the installation column 4 and the pile foundation 1.

[0042] Preferably, in this embodiment, Figure 1As shown, the mounting frame also includes a support frame 5. Specifically, the upper end of the support frame 5 is connected to the side of the construction platform 6 facing away from the mounting column 4, and the lower end of the support frame 5 extends obliquely downward and is connected to the mounting frame. The support frame 5 can improve the support strength of the mounting frame, improve the support stability of the construction platform 6, and ensure the safety of the workers.

[0043] Preferably, in this embodiment, both ends of the support frame 5 are hingedly connected to the construction platform 6 and the installation pillars, respectively, so that the actual assembly of the support frame 5 is convenient.

[0044] In this embodiment, if Figure 1 , 2 As shown, the driving mechanism includes a hydraulic cylinder 7, and the hydraulic cylinder 7 is integrally arranged inside the scissor frame structure 9. In this way, the hydraulic cylinder 7 can be used to ensure the lifting stability of the lifting platform 12, and on the other hand, it is convenient to adjust the height position of the lifting platform 12. At the same time, the scissor frame structure 9 can be used to protect the hydraulic cylinder 7, thereby improving the operating safety of the hydraulic cylinder 7. In this embodiment, as shown in FIG. Figure 2 As shown, the scissor frame structure 9 is provided with multiple groups of scissor frames in the vertical direction. What is not shown in the figure is that the scissor frame structure 9 is symmetrically provided with two groups in the longitudinal direction (i.e., the width direction of the upper end surface of the construction platform 6), and the hydraulic cylinders 7 are also symmetrically provided with two groups in the longitudinal direction, so as to ensure the lifting stability of the lifting platform 12. Of course, in other embodiments, when meeting actual needs, the hydraulic cylinders 7 can be provided on the outside of the scissor frame structure 9. In this case, a hydraulic cylinder 7 is provided on both sides of the scissor frame structure 9 in the transverse direction, and a total of four hydraulic cylinders 7 are provided on the entire construction platform 6 to ensure the lifting stability of the lifting platform 12.

[0045] Preferably, in this embodiment, the hydraulic cylinder 7 is arranged vertically, wherein the lower end support of the cylinder body of the hydraulic cylinder 7 is fixedly mounted on the upper end surface of the construction platform 6, the upper end of the telescopic cylinder of the hydraulic cylinder 7 is the output end, and the output end support is fixedly mounted on the lower end surface of the lifting platform 12. In this way, the output direction of the hydraulic cylinder 7 is parallel to the lifting direction of the lifting platform 12, which facilitates the hydraulic cylinder 7 to apply force to the lifting platform 12.

[0046] Preferably, in this embodiment, Figure 1 As shown, the height of the upper end of the mounting frame is not higher than the height of the upper end of the cylinder body of the hydraulic cylinder 7, that is, the height of the upper end of the mounting column 4 is not higher than the height of the upper end of the cylinder body of the hydraulic cylinder 7. This arrangement can avoid interference between the lifting platform 12 and the mounting frame during the lifting process, and can correspondingly increase the working space of the lifting platform 12.

[0047] Preferably, in this embodiment, a protective fence 10 is provided on the lifting platform 12, and a platform railing 8 is provided on the construction platform 6. This can protect the workers and improve the safety of the operation.

[0048] The installation process of the pile-based photovoltaic module of the present invention is as follows: first, the pile foundation 1 is installed at the construction location, the lower end of the pile foundation 1 is extended into and fixed to the seabed H, then the liftable construction platform is transported to the position of the pile foundation 1, and then the lower end of the installation column 4 of the liftable construction platform is connected to the fixed lifting ear 3, and the installation support is fixed to the pile foundation 1 by using the clamp 2 to complete the installation of the liftable construction platform.

[0049] The upper support 11 is placed on the upper end of the pile foundation 1 by means of shipping and hoisting, etc., to complete the preliminary installation.

[0050] The staff enters the construction platform 6 and starts the lifting mechanism. The staff rises to the connection position between the pile foundation 1 and the upper bracket 11 through the lifting platform 12 to fix the upper bracket 11 and the pile foundation 1. After the construction is completed, the lifting platform 12 is lowered and the staff returns.

[0051] Embodiment 2: This embodiment provides a different lifting device. Different from Embodiment 1, in this embodiment, Figure 3 , 4 As shown, the lower end of the cylinder body of the hydraulic cylinder 7 is hingedly connected to the upper end surface of the construction platform 6, and the upper end of the telescopic cylinder of the hydraulic cylinder 7 is hingedly connected to the scissor frame structure 9. Specifically, the cylinder body of the hydraulic cylinder 7 is arranged on the side of the construction platform 6 facing the pile foundation 1, and the upper end of the telescopic cylinder is hingedly connected to a scissor frame at the uppermost end of the scissor frame structure 9 and the lower side of the cylinder body, so that in actual operation, the height of the cylinder body of the hydraulic cylinder 7 can change with the extension and contraction of the scissor frame. When the scissor frame is compressed, the overall height of the hydraulic cylinder 7 can be reduced as the lower end of the hydraulic cylinder 7 rotates, thereby making the lifting platform 12 lower and more compact as a whole, and at the same time facilitating the workers to enter and exit the lifting platform 12.

[0052] Example 3: This example provides a different lifting mechanism. Different from Example 1, in this example, the driving mechanism includes a driving motor and a driving screw, wherein the driving motor is fixedly arranged on the upper end surface of the construction platform, the lower end of the driving screw is connected to the output end of the driving motor, and the upper end of the driving screw extends upward. A threaded through hole matching the driving screw is provided at a position corresponding to the driving screw on the lifting platform, and the driving screw is threadedly connected in the threaded through hole.

[0053] An upwardly extending guide rod is fixedly provided at the four corners of the end face of the construction platform, and a guide hole matching the guide rod is correspondingly provided on the lifting platform. The guide rod slides through the guide hole, so that the driving motor is used to drive the driving screw to rotate, and the scissor frame structure and the guide rod are used for guidance. The driving screw can drive the lifting platform to rise and fall during the rotation process.

[0054] The utility model provides an embodiment of a liftable construction platform for a pile-based photovoltaic assembly. The liftable construction platform for the pile-based photovoltaic assembly of the utility model has the same structure as the liftable construction platform for the pile-based photovoltaic assembly in the above-mentioned embodiment, and will not be described in detail here.

For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.

[0056] In the description of the embodiments of the present application, it should be noted that if the terms "upper", "lower", "horizontal", "inner", etc. indicate an orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0057] In addition, if the term "horizontal" appears, it does not mean that the component must be absolutely horizontal, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", which does not mean that the structure must be completely horizontal, but can be slightly tilted.
