Description

Technical Field

[0001] The utility model relates to the field of photovoltaic power generation systems, in particular to a sliding installation system for photovoltaic modules of a flexible support. Background Art

[0002] With the growth of the global demand for renewable energy and the progress of technology, solar photovoltaic power generation has developed rapidly as a clean and sustainable energy form. In particular, flexible support systems have been widely used in various integrated energy scenarios such as agricultural-photovoltaic complementary, fishery-photovoltaic complementary, and pastoral-photovoltaic complementary due to their unique characteristics such as high capacity, high clearance, large span, multi-span connection, and multi-row connection. However, with the continuous increase in the single-span length and multi-span length of flexible support systems, the existing photovoltaic module installation technologies face many challenges.

[0003] During the installation process of photovoltaic modules of traditional flexible supports, the following disadvantages exist:

[0004] 1. Traditional photovoltaic module installation methods usually rely on manual handling or large-scale lifting machinery, which is not only inefficient but also difficult to implement under complex terrain conditions;

[0005] 2. Using large-scale lifting machinery for installation not only increases the cost of equipment rental but also may lead to additional costs due to the complexity of equipment transportation and on-site operation;

[0006] 3. When carrying out installation operations on flexible support systems with large spans and multi-span connections, due to the need for frequent high-altitude operations, there are relatively high safety risks;

[0007] 4. During the handling process, photovoltaic modules are easily collided and squeezed, resulting in component damage or performance degradation;

[0008] In view of the above problems, there is an urgent need in the market for an efficient and safe photovoltaic module installation method that can adapt to the structural characteristics of large spans and multi-span connections. Especially for flexible support systems, such systems often require photovoltaic modules to be accurately installed at designated positions without the aid of large-scale lifting machinery. Summary of the Utility Model

[0009] The technical problem to be solved by the utility model is to provide a sliding installation system for photovoltaic modules of a flexible support, so as to solve the problems of low efficiency, high cost, safety hazards, and component breakage existing in the prior art, and provide a more efficient, economical, and safe solution for the installation of photovoltaic modules of flexible support systems.

[0010] To solve the above technical problems, the technical solution adopted by the utility model is:

[0011] A sliding installation system for photovoltaic modules with a flexible support, comprising side columns and side beams, middle columns and beams, and a towing hook. A component cable is connected between the side columns and side beams and the middle columns and beams. The photovoltaic modules are placed on the component cable, and the side of the photovoltaic module is movably clamped to the towing hook. One side of the towing hook is connected to a towing rope, and the other side of the towing hook is connected to a circulating rope. The towing rope drags the towing hook and drives the photovoltaic module to slide along the component cable.

[0012] In a preferred embodiment, a circulating pulley is installed on the side columns and side beams. The circulating rope passes around the circulating pulley and is connected to the towing hook.

[0013] In a preferred embodiment, a towing pulley is installed on the middle columns and beams. The towing rope passes around the towing pulley and is connected to the towing hook.

[0014] In a preferred embodiment, a lifting pulley is installed on the side columns and side beams.

[0015] In a preferred embodiment, a safety ring is provided on the component cable. The safety ring slides along the component cable in a limited manner. The towing rope and the circulating rope pass through the safety ring and are connected to the towing hook.

[0016] In a preferred embodiment, the towing hook comprises a towing hook section, a straight section, and a towing rope loop; the towing hook section, the straight section, and the towing rope loop are connected in sequence to form the towing hook body. The towing hook section is connected to the circulating rope, the towing rope loop is connected to the towing rope, and the photovoltaic module is clamped between the towing hook section and the straight section during sliding.

[0017] In a preferred embodiment, the inner side of the straight section is hinged to a safety buckle plate through a hinge. The safety buckle plate rotates freely around the hinge, and a spring is provided between the safety buckle plate and the straight section.

[0018] In a preferred embodiment, the outer sides of the towing hook section, the straight section, and the towing rope loop are coated with a PE outer skin.

[0019] A sliding installation system for photovoltaic modules with a flexible support has the following beneficial effects during use:

[0020] 1. By adopting the circulating traction sliding method, the rapid positioning and installation of photovoltaic modules are realized, reducing the repeated climbing operations of workers, reducing the risk of falling from heights, and at the same time reducing the additional bending moment and vertical tension during the installation of photovoltaic modules, reducing the risk of deformation and hidden cracks of photovoltaic modules and improving the overall construction efficiency;

[0021] 2. Using simple and practical tools (such as towing hooks, U-shaped rings, towing ropes, circulating ropes, pulley blocks, etc.) reduces the physical burden of workers and improves the construction conditions;

[0022] 3. The design of the towing hook ensures non-destructive contact with the photovoltaic module, avoids damage to the module during installation, and reduces the breakage rate of the module.

[0023] 4. For the case where the height of the crossbeam of the flexible support system from the ground is relatively high, the construction efficiency can be further improved by installing a hoisting pulley block to ensure the safe hoisting and installation of the photovoltaic modules.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0031] As Figure 1 shown, a slip installation system for photovoltaic modules of a flexible support includes a side column and side beam 1, a middle column beam 2 and a towing hook 7. A component cable 3 is connected between the side column and side beam 1 and the middle column beam 2. The photovoltaic module 5 is placed on the component cable 3. The side of the photovoltaic module 5 is movably clamped with the towing hook 7. One side of the towing hook 7 is connected to a towing rope 6, and the other side of the towing hook 7 is connected to a circulating rope 4. The towing rope 6 drags the towing hook 7 and drives the photovoltaic module 5 to slide along the component cable 3;

[0032] Before construction, first install a circulating traction system composed of a pulley block, a towing rope 6, a circulating rope 4 and a towing hook 7. Then string the photovoltaic modules 5 on two component cables 3 on the assembly side. The circulating traction system traction the photovoltaic modules 5 to slide uniformly towards the traction side. After being towed to the designed position, the photovoltaic modules 5 are fixed. The circulating rope 5 then drags the towing hook 7 and the towing rope 6 back, and continues to circulate and tow the newly assembled photovoltaic modules 5 until the installation is completed.

[0033] The preferred solution is asFigure 1 , Figure 4 and Figure 5 As shown in Figure 1 , Figure 4 and Figure 5 , a circulating pulley 8 is installed on the side column and side beam 1, and the circulating rope 4 is connected to the towing hook 7 after passing around the circulating pulley 8; a towing pulley 11 is installed on the middle column beam 2, and the towing rope 6 is connected to the towing hook 7 after passing around the towing pulley 11; through the above structure, the staff can complete the work on the ground and avoid working at heights.

[0034] Preferably, as shown in Figure 4 Figure 4 , a lifting pulley 9 is installed on the side column and side beam 1 to facilitate the lifting of the photovoltaic module 5 to be installed.

[0035] Preferably, as shown in Figure 4 Figure 4 , a safety ring 10 is provided on the component cable 3, and the safety ring 10 is limited to slide along the component cable 3. The towing rope 6 and the circulating rope 4 pass through the safety ring 10 and are connected to the towing hook 7. The safety ring 10 adopts a U-shaped ring structure. When the safety ring 10 works, it is buckled on the component cable (main cable). When the photovoltaic module is towed in place and the tow hook is removed, it is ensured that the towing hook 7 will not fall, and it is ensured that the circulating rope 4 and the towing hook 7 can be smoothly retracted along the component cable 3. At the same time, it can also ensure that the circulating rope 4 and the towing rope 6 will not cause entanglement during work.

[0036] Preferably, as shown in Figure 2 and Figure 3 Figure 2 and Figure 3 , the towing hook 7 includes a towing hook section 701, a straight section 702 and a towing rope loop 703; the towing hook section 701, the straight section 702 and the towing rope loop 703 are connected in sequence to form the towing hook 7 body. The towing hook section 701 is connected to the circulating rope 4, and the towing rope loop 703 is connected to the towing rope 6. When the photovoltaic module 5 slides, it is clamped between the towing hook section 701 and the straight section 702;

[0037] The towing hook 7 is made of flat steel, which is convenient for material taking and easy to process, ensuring non-destructive contact with the photovoltaic module 5, and the contact surface is a large-area plane, and it can prevent the towing hook from rotating left and right during towing. Usually, the straight section 702 is designed to be 300 mm, which is bent from a 40 mm * 4 mm hot-rolled flat steel. The towing hook section 701 is a U-shaped towing hook with a bending radius of 35 mm and a straight section length of 100 mm for the towing hook. The circular ring of the towing rope loop 703 is tangent to the straight section of the towing hook, ensuring that the contact surface between the towing hook 7 and the photovoltaic module 5 is a plane.

[0038] Preferably, as shown in Figure 2 and Figure 3As shown, the inner side of the straight line segment 702 and the safety buckle plate 704 are hinged through a hinge 705. The safety buckle plate 704 rotates freely around the hinge 705. A spring 706 is arranged between the safety buckle plate 704 and the straight line segment 702. Under normal circumstances, the safety buckle plate 704 is locked with the towing hook segment 701 under the action of the spring 706 to prevent the towing hook 7 from being stuck with the photovoltaic module 5. The 120° inner bend angle of the safety buckle plate 704 is to prevent the safety buckle 11 from hooking the aluminum alloy frame of the photovoltaic module 5 when removing the towing hook.

[0039] The preferred solution is as Figure 2 and Figure 3 shown. The outer sides of the towing hook segment 701, the straight line segment 702 and the towing rope loop 703 are coated with a PE outer skin, which plays a role in protecting the photovoltaic module 5 during the towing process.

[0040] The usage steps of this system are as follows:

[0041] S1. Complete the first tensioning of the component cable 3, transport the photovoltaic module 5 in place, install a mobile scaffolding or a water operation platform, and set necessary safety measures;

[0042] S2. Install pulley blocks on the cross beams at both ends of the flexible support, deploy the towing rope 6 and the circulating rope 4, and connect them to the towing hook 7. Install the safety ring 10 on the component cable 3;

[0043] S3. Temporarily fix the photovoltaic module 5 on the component cable 3 with aluminum alloy connectors on the assembly side, use the towing hook 7 to hook the photovoltaic module 5, and tow the photovoltaic module 5 to the designed position at a uniform speed;

[0044] S4. After towing the photovoltaic module 5 to the designed position, perform final fastening and connect the grounding wire, unhook the towing hook 7, and tow it back to the assembly side using the circulating rope 4;

[0045] S5. Repeat the above process until the installation of the photovoltaic module 5 in this span is completed.
