Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic technology, specifically to a high-altitude operation device for assembling marine photovoltaic grid structures. Background Technology

[0002] Against the backdrop of global energy structure transformation, the development and utilization of renewable energy has attracted much attention. Among them, offshore photovoltaic projects, with their abundant solar energy resources and vast exploitable sea areas, have become a new hotspot in the energy sector in recent years.

[0003] In offshore photovoltaic projects, the first step is to assemble the offshore photovoltaic grid on land, then install the photovoltaic panels on the grid, and finally transport the entire structure to the sea for installation. Because the offshore photovoltaic grid is quite tall, high-altitude work is required. Furthermore, the grid members are intertwined, and the work site conditions are complex and unique, making conventional high-altitude work aids such as ladders and mobile operating platforms unsuitable.

[0004] In the current technology, a common method used in the industry for temporarily setting up a work platform is to hang four S-shaped hooks in pairs on two adjacent parallel rods. Then, two narrow steel plates are placed at the lower end of the hooks along the length of the rods. The two narrow steel plates are arranged in parallel and on the same horizontal plane. Finally, two wide steel plates are placed perpendicular to the narrow steel plates and close to the inside of the hooks to form the work platform.

[0005] This type of work platform, which can be constructed using the interlaced members of a space frame, offers high flexibility and is suitable for photovoltaic panel installation on such structures. However, in actual use, firstly, the S-hooks directly contact the members, and the swaying of these hooks during operation can easily damage the anti-corrosion layer of the space frame members, causing quality problems. Secondly, the hooks are in a swinging state during operation, and the wide steel plate rests solely on the narrow steel plate under its own weight, generally without any securing measures, posing a significant safety hazard and increasing the risk of workers falling from heights. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a high-altitude operation device for assembling offshore photovoltaic grid structures. It uses a fixed structure, longitudinal support plate and transverse mounting plate to form a rigid operation platform, which solves the swaying problem of existing high-altitude operation platforms during operation, reduces the risk of high-altitude operations, and uses anti-slip protective pads to prevent the rigid operation platform from directly contacting and damaging the anti-corrosion layer of the poles, thus preventing quality problems.

[0007] To address the aforementioned technical problems, this utility model provides a high-altitude operation device for assembling offshore photovoltaic grid structures. It includes two parallel longitudinal support plates, on which two transverse mounting plates are sequentially erected and fixed. Each longitudinal support plate has a set of fixing structures at both ends. Each fixing structure includes a fixing rod and a clamp assembly at the upper end of the fixing rod. The lower end of the fixing rod is fixed to the longitudinal support plate. The clamp assembly has an anti-slip protective pad attached to its interior. Four sets of clamp assemblies are used to be paired and fixed to the two horizontal members of the grid structure.

[0008] Furthermore, the fixing rod includes a first vertical rod and a horizontal extension section disposed at the lower end of the first vertical rod and extending inward therein, and the longitudinal support plate is fixedly situated on the horizontal extension section.

[0009] Furthermore, the horizontal extension section extends laterally, and the lateral dimension of the horizontal extension section is adapted to the lateral width of the longitudinal support plate. The end of the horizontal extension section facing away from the first vertical rod is provided with an upwardly extending vertical section, and the longitudinal support plate is engaged between the vertical section and the first vertical rod.

[0010] Furthermore, the height of the vertical section is greater than the height of the longitudinal support plate.

[0011] Furthermore, the horizontal extension section is fixedly connected to the longitudinal support plate by a bolt assembly.

[0012] Furthermore, the clamp assembly includes a first clamping ring and a second clamping ring, wherein the first clamping ring is integrally formed with the fixing rod.

[0013] Furthermore, the anti-slip protective pad is made of PVC.

[0014] Furthermore, the transverse mounting plate is a U-shaped plate with an opening facing downwards. The U-shaped plate has a matching snap-fit ​​notch at the position corresponding to the longitudinal support plate. The transverse mounting plate is snapped and fixed to the longitudinal support plate through the snap-fit ​​notch.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The lower end of the fixed rod is fixed to the longitudinal support plate, and the clamp assembly at the upper end of the fixed rod is sleeved and fixed to the two horizontal members of the space frame. A transverse mounting plate is fixedly erected on the longitudinal support plate, making the whole device a rigid structure, which can provide a more stable and reliable support structure. During operation, the device is fixed to the space frame to avoid shaking. At the same time, the transverse mounting plate is fixed to the longitudinal support plate to prevent slippage and fall during operation, reducing the risk of working at height and improving safety. The inside of the clamp assembly is fitted with an anti-slip protective pad, which can increase the friction between the clamp assembly and the rod to prevent swaying due to excessive force during operation. On the other hand, it can also protect the rod to prevent the clamp assembly from directly contacting the rod and damaging the anti-corrosion layer, which would lead to quality problems.

[0017] (2) A horizontal extension section is provided at the lower end of the first vertical bar, which can provide a better support foundation for the longitudinal support plate and ensure that the longitudinal support plate and the fixed bar are fixed reliably.

[0018] (3) The vertical section can be used in conjunction with the first vertical rod to clamp the longitudinal support plate between the two, so as to achieve precise positioning and effective fixation of the longitudinal support plate, prevent the longitudinal support plate from moving in the horizontal and vertical directions, further enhance the overall stability of the device, and ensure personnel safety.

[0019] (4) The height of the vertical section is greater than the height of the longitudinal support rod. After installation, the upper end of the vertical section extends out of the longitudinal support plate. On the one hand, it makes it easier for operators to intuitively perceive the operating boundary, and on the other hand, it can block the horizontal installation plate and play a side protection role.

[0020] (5) The horizontal mounting plate is a U-shaped plate with the opening facing downwards. While improving the strength and load-bearing capacity of the horizontal mounting plate, it can relatively reduce the weight of the horizontal mounting plate, improve portability, reduce the difficulty of operation, and make it easy to position and fix the horizontal mounting plate and the longitudinal support plate by using the snap-fit ​​notch, which facilitates assembly and disassembly.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings: Specific Implementation Example 1:

[0028] In this embodiment, as Figure 3 As shown, the horizontal direction is the length direction of the horizontal mounting plate 3, and the vertical direction is the length direction of the vertical support plate 2.

[0029] refer to Figures 1 to 4 This utility model discloses a high-altitude work device (hereinafter referred to as a high-altitude work device) for assembling offshore photovoltaic grid structures, comprising two parallel longitudinal support plates 2, which are located on the same horizontal plane. Two transverse mounting plates 3 are sequentially erected and fixed on the longitudinal support plates 2, forming a rigid work platform. In this embodiment, each longitudinal support plate 2 has a set of fixing structures at both ends, and the rigid work platform is fixedly installed on the offshore photovoltaic grid structure through these fixing structures.

[0030] Specifically, in this embodiment, two longitudinal support plates 2 are arranged at a horizontal interval, and two transverse mounting plates 3 are arranged at a longitudinal interval. Of course, in other embodiments, depending on the actual size requirements, the two longitudinal support plates 2 can also be arranged adjacent to each other, and similarly, the two transverse mounting plates 3 can also be arranged adjacent to each other. The fixing structure includes a fixing rod 7 and a clamp assembly 1 set on the upper end of the fixing rod 7. The lower end of the fixing rod 7 is fixed to the longitudinal support plate 2. The clamp assembly 1 is provided with an anti-slip protective pad 4 inside. Four sets of clamp assemblies 1 are used to be fitted and fixed in pairs on the two horizontal members 6 of the space frame, thereby fixing the high-altitude operation device to the space frame.

[0031] With this configuration, the lower end of the fixing rod 7 is fixed to the longitudinal support plate 2, and the clamp assembly 1 at the upper end of the fixing rod 7 is sleeved and fixed to the two horizontal members 6 of the space frame. A transverse mounting plate 3 is fixedly erected on the longitudinal support plate 2, making the entire device a rigid structure that provides a more stable and reliable support structure. During operation, the device is fixed to the space frame to prevent swaying. Simultaneously, the transverse mounting plate 3 is fixed to the longitudinal support plate 2 to prevent slippage and detachment during operation, reducing the risk of working at heights and improving safety. An anti-slip protective pad 4 is attached inside the clamp assembly 1. This increases friction between the clamp assembly 1 and the members 6, preventing swaying due to excessive force during operation. It also protects the members 6 from direct contact, preventing damage to the anti-corrosion layer and potential quality problems.

[0032] In this embodiment, preferably, such as Figure 1 As shown, the fixing rod 7 includes a first vertical rod 71 and a horizontal extension section 72 located at the lower end of the first vertical rod 71 and extending inward. The upper end of the first vertical rod 71 is fixedly connected to the clamp assembly 1, and the longitudinal support plate 2 is fixedly mounted on the horizontal extension section 72. This arrangement provides a better support foundation for the longitudinal support plate 2, ensuring reliable fixation between the longitudinal support plate 2 and the fixing rod 7.

[0033] Specifically, in this embodiment, the horizontal extension segment 72 extends laterally, and its lateral dimension matches the lateral width of the longitudinal support plate 2. A vertically extending segment 73 is provided at the end of the horizontal extension segment 72 facing away from the first vertical rod 71. The distance between the vertical segment 73 and the first vertical rod 71 matches the width of the longitudinal support plate 2. The longitudinal support plate 2 is positioned between the vertical segment 73 and the first vertical rod 71. This arrangement facilitates precise positioning and effective fixation of the longitudinal support plate 2, preventing it from shifting horizontally and vertically, further enhancing the overall stability of the device and ensuring personnel safety.

[0034] In this embodiment, preferably, the height of the vertical section 73 is greater than the height of the longitudinal support plate 2. Specifically, the upper end of the vertical section 73 extends beyond the transverse mounting plate 3. This arrangement, after installation, allows operators to visually perceive the operating boundaries, while also blocking the transverse mounting plate 3 for lateral protection. Simultaneously, it prevents the longitudinal support plate 2 from detaching from the horizontal extension section 72, thus improving safety.

[0035] Preferably, in this embodiment, mounting holes are provided at corresponding positions of the horizontal extension section 72 and the longitudinal support plate 2, and the horizontal extension section 72 and the longitudinal support plate 2 are fixedly connected together by bolt assembly 5. On the one hand, the shape of the horizontal extension section 72 is used to hold the longitudinal support plate 2 in place, so that the longitudinal support plate 2 can be placed stably and reliably. On the other hand, the bolt assembly 5 is used to fix the longitudinal support plate 2, which improves the reliability of the fixation between the longitudinal support plate 2 and the fixed structure, and can prevent movement during operation or personnel and the longitudinal support plate 2 from falling due to excessive load on one end, thus forming a double insurance.

[0036] Of course, in other embodiments, when meeting actual usage requirements, the bolt assembly 5 may not be provided. In this case, mounting through holes are provided on the opposite sides of the vertical section 73 and the first vertical rod 71. The position of the mounting through holes is slightly higher than that of the longitudinal support plate 2. A stop bar is provided in the two mounting through holes. One end of the stop bar is provided with a through hole. A fixing stop pin is provided in the through hole. The stop bar is used to stop the longitudinal support plate 2 to prevent it from falling off. At the same time, the friction between the longitudinal support plate 2 and the first vertical rod 71 and the vertical section 73 is used to keep it fixed.

[0037] In other embodiments, when meeting actual needs, the lower end of the fixing rod 7 may not be provided with a horizontal extension section 72. In this case, an outwardly extending screw is provided on the side of the longitudinal support plate 2 corresponding to the fixing rod 7, and a through hole is provided at the lower end of the fixing rod 7. The through hole of the fixing rod 7 is sleeved on the corresponding screw and fixedly connected by a nut, so as to realize the detachable fixing of the fixing rod 7 and the longitudinal support plate 2.

[0038] In other embodiments, when meeting actual usage requirements, the horizontal extension section 72 can extend longitudinally, and the vertical section 73 is no longer provided. The horizontal extension section 72 is set at the lower part of the longitudinal support plate 2, hooks and supports the longitudinal support plate 2 and is fixedly connected together by the bolt assembly 5.

[0039] In this embodiment, preferably, the clamp assembly 1 includes a first clamping ring 12 and a second clamping ring 13. Vertical clamping short plates 11 are provided at the upper and lower ends of both the first clamping ring 12 and the second clamping ring 13. The opposing clamping short plates 11 are fixedly connected by bolt assemblies 5 to achieve locking of the clamp assembly 1. The clamping short plate 11 at the lower end of the first clamping ring 12 is fixedly connected to the fixing rod 7.

[0040] Specifically, in this embodiment, the first clamping ring 12 is integrally formed with the first vertical rod 71 of the fixing rod 7. The first clamping ring 12 is also positioned outside the second clamping ring 13, facilitating the arrangement of the horizontal extension section 72 and the vertical section 73. The integrally formed components reduce connection points, improve the overall strength and stability of the clamping assembly 1, and allow for better fitting and fixing to the space frame rods 6. This effectively prevents the clamping assembly 1 from loosening or deforming during operation, ensuring a reliable connection between the working device and the space frame.

[0041] Preferably, in this embodiment, the anti-slip protective pad 4 is made of PVC, which has good flexibility, wear resistance, and anti-slip properties. In other embodiments, the anti-slip protective pad 4 may also be made of silicone.

[0042] Preferably, in this embodiment, the transverse mounting plate 3 is a U-shaped plate with the opening facing downwards, and the U-shaped plate has a snap-fit ​​notch 31 that is adapted to the longitudinal support plate 2 at the position corresponding to the longitudinal support plate 2. The transverse mounting plate 3 is snapped and fixed on the longitudinal support plate 2 through the snap-fit ​​notch 31. Considering the length, width and weight of the transverse support plate, it is only necessary to set a groove to fix it on the longitudinal support plate 2, which not only saves materials, but also facilitates installation and disassembly.

[0043] The transverse mounting plate 3 is a U-shaped plate with its opening facing downwards. While improving the strength and load-bearing capacity of the transverse mounting plate 3, its weight can be relatively reduced, improving portability and simplifying operation. The snap-fit ​​notch 31 facilitates the positioning and fixing of the transverse mounting plate 3 to the longitudinal support plate 2, making assembly and disassembly convenient. In other embodiments, to improve connection reliability, a bolt assembly 5 can be provided between the longitudinal support plate 2 and the transverse mounting plate 3 for fixation.

[0044] The working process of this application:

[0045] Based on the actual conditions of working at height, select a fixed structure of appropriate length, and longitudinal support plate 2 and transverse mounting plate 3 of appropriate length and width.

[0046] First, the four sets of clamping assemblies 1 are clamped and fixed to the two adjacent horizontal members 6 (i.e., the round steel of the space frame). The first clamping ring 12 is arranged on the outside, and the lower horizontal extension section 72 is extended inward along the transverse direction (i.e., perpendicular to the horizontal member 6). The two horizontal extension sections 72 on the same longitudinal side are coplanar to form a support plate for a single longitudinal support plate 2 to sit on.

[0047] The longitudinal support plates 2 are placed on the horizontal extension sections 72 on both sides, keeping the longitudinal support plates 2 parallel to the horizontal members 6, and the ends of the longitudinal support plates 2 are fixed to the corresponding horizontal extension sections 72 using bolt assemblies 5. The transverse mounting plate 3 is vertically snapped and fixed to the longitudinal support plates 2 using snap-fit ​​notches 31. The overall installation of the device is completed.

[0048] The aerial work platform can then be used to facilitate the installation of photovoltaic panels.

[0049] In summary, the aerial work device of this utility model effectively solves the swaying problem of existing aerial work platforms during operation, greatly reduces the risk of working at heights, provides workers with a safe and reliable working condition, and at the same time prevents the rigid clamp assembly 1 from directly contacting and damaging the anti-corrosion layer, thus preventing quality problems and improving efficiency.

[0050] Example 2: This example provides a different first vertical rod. Unlike Example 1, in this example, the first vertical rod is segmented, including a first segment and a second segment along the vertical direction. Multiple connecting holes are provided at intervals along the vertical direction on the first segment and the second segment. The first segment and the second segment are fixedly assembled by bolt assemblies passing through the corresponding connecting holes. In this way, the length of the first vertical rod can be adjusted by adjusting the corresponding positions of the relative connecting holes, thereby improving practicality.

[0051] Example 3: This example provides a different longitudinal support plate and transverse mounting plate. Unlike Example 1, in this example, the longitudinal support plate is a longitudinal telescopic plate with an adjustable length along the longitudinal direction, and the transverse mounting plate is a transverse telescopic plate with an adjustable length along the transverse direction. This allows for adjustment of the working area of ​​the entire rigid work platform, adapting to different sizes of working spaces and improving practicality.

[0052] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0053] In the description of the embodiments of this application, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0054] Furthermore, the use of the term "horizontal" does not imply that the component must be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.
