Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, specifically a windproof and reinforced component that enhances the wind resistance of photovoltaic modules. Background Technology

[0002] Photovoltaic power generation is a technology that directly converts sunlight into electrical energy using the "photovoltaic effect." Its core device is the photovoltaic panel (also known as a solar panel). A photovoltaic panel is composed of a large number of solar cells made of semiconductor materials (such as silicon). When sunlight shines on these cells, photons excite electrons to move in a specific direction, thereby generating direct current (DC) to provide clean energy for homes, businesses, and even the power grid.

[0003] With the popularization of solar energy technology, the deployment scale of photovoltaic power stations is expanding, and their installation environments are becoming increasingly diverse, commonly found on rooftops, plains, mountains, and even coastal areas. These areas frequently encounter severe weather such as strong winds and typhoons, posing a serious threat to the stability of photovoltaic arrays. Traditional photovoltaic module fixing methods mostly use clamps and guide rails for direct locking, which has limited wind resistance. Under strong winds, the modules are at risk of vertical shaking, front-to-back displacement, or even being completely overturned, leading to damage such as module microcracks, frame deformation, and fatigue fracture of fasteners, resulting in huge economic losses. Although there are solutions in existing technologies to strengthen the system by increasing the weight of the support frame or using more bolts, these have disadvantages such as cumbersome installation, high material costs, and high requirements for the original foundation load.

[0004] Therefore, there is an urgent need for a special windproof reinforcement component that is simple in structure, easy to install, and can effectively suppress the vibration and displacement of photovoltaic modules under wind load. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a windproof and reinforced component that enhances the wind resistance of photovoltaic modules. It has the advantages of simple structure and convenient installation, and solves the problems mentioned in the background technology.

[0007] As a preferred embodiment of this utility model, the elastic pressure mechanism includes a lifting plate, a nut threadedly connected to a lead screw is installed in the middle of the lifting plate, two rod grooves are opened on both sides of the lifting plate, a slide rod is slidably connected to the rod groove, a compression spring is sleeved on the surface of the slide rod, a baffle is fixedly provided at the top of the slide rod, and the bottom end of the slide rod is fixedly connected to the top of the clamping plate.

[0008] As a preferred technical solution of this utility model, guide posts are fixedly provided on the inner walls of both sides of the top of the clamping frame, and column grooves that are slidably connected to the guide posts are provided on both sides of the lifting plate.

[0009] As a preferred embodiment of the present invention, the self-locking mechanism includes a pawl, which is engaged with a ratchet wheel. A rotating shaft is fixedly provided at the bottom end of the pawl, and the rotating shaft is rotatably connected to the top end of the clamping frame. A torsion spring is sleeved on the surface of the rotating shaft.

[0010] As a preferred embodiment of this utility model, one side of the torsion spring is engaged with a pawl, and the other side of the torsion spring is engaged with a baffle, the bottom end of which is fixedly connected to the top end of the clamping frame.

[0011] As a preferred embodiment of this utility model, the top of the lead screw is rotatably connected to the middle of the top of the clamping frame, and the bottom of the lead screw is rotatably connected to a support, which is fixedly connected to the inside of the clamping frame.

[0012] As a preferred embodiment of this utility model, the top end of the protective cylinder is provided with a groove, and a sealing gasket is engaged inside the groove. A protective cover is fixedly installed on the top end of the protective cylinder by screws.

[0013] As a preferred embodiment of this utility model, a second rubber pad is bonded to the inner wall of the bottom end of the clamping frame, and both the surface of the first rubber pad and the surface of the second rubber pad are coated with an anti-aging agent.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. By bridging the frames of two adjacent photovoltaic modules, the screw is rotated using a knob. The screw drives the elastic pressure mechanism to descend. The elastic pressure mechanism transmits pressure to the frame of the photovoltaic module through the clamping plate and provides pre-tight clamping force, reducing pressure fluctuations. The clamping plate can stably hold the frame of the photovoltaic module through the rubber pad. The structure is simple, easy to install, and not easy to loosen or fall off. It can effectively restrain the vertical shaking and front-back displacement of the photovoltaic module under wind load, significantly improving the wind resistance of the photovoltaic array.

[0016] 2. The self-locking mechanism ensures unidirectional rotation of the lead screw. After rotation, it prevents the lead screw from retracting, thus achieving a self-locking effect. The protective sleeve at the top of the clamp frame provides shielding protection for the knob and the self-locking mechanism. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5A wind-resistant reinforcement component to enhance the wind resistance of photovoltaic modules includes a frame 1. Inside the frame 1 are two clamping plates 2. Rubber pads 10 are adhered to the bottom of the clamping plates 2. A lead screw 3 is rotatably mounted inside the frame 1. The lead screw 3 is connected to an elastic pressure mechanism 4 that applies pressure to the clamping plates 2. A ratchet 5 is fixed to the top of the lead screw 3. A self-locking mechanism 6 is provided at the top of the frame 1 to lock the ratchet 5. A knob 7 is fixed to the top of the ratchet 5. A wrench position 8 is located in the middle of the top of the knob 7. The top of the frame 1 provides protection for the knob 7 and the self-locking mechanism 6. The protective cylinder 9, by bridging the frame 1 across the frame of two adjacent photovoltaic modules, uses the knob 7 to rotate the lead screw 3, which drives the elastic pressure mechanism 4 to descend. The elastic pressure mechanism 4 can transmit pressure to the frame of the photovoltaic module through the clamping plate 2 and provide pre-tight clamping force, reducing pressure fluctuation. The clamping plate 2 can stably clamp the frame of the photovoltaic module through the rubber pad 10. The structure is simple and easy to install. It can effectively restrain the vertical shaking and front-back displacement of the photovoltaic module under wind load, and significantly improve the wind resistance of the photovoltaic array.

[0025] In this embodiment, preferably, the elastic pressure mechanism 4 includes a lifting plate 401. A nut threadedly connected to the lead screw 3 is installed in the middle of the lifting plate 401. Two rod grooves 402 are opened on both sides of the lifting plate 401. A sliding rod 403 is slidably connected to the rod groove 402. A compression spring 404 is sleeved on the surface of the sliding rod 403. A baffle 405 is fixedly provided at the top of the sliding rod 403. The bottom end of the sliding rod 403 is fixedly connected to the top of the clamping plate 2. Guide posts 12 are fixedly provided on the inner walls of both sides of the top of the clamping frame 1. The lifting plate 401... Both sides of 1 are provided with column grooves 406 that are slidably connected to guide posts 12. The rotational motion of lead screw 3 can be converted into linear motion of lifting plate 401 by nuts. Guide posts 12 and column grooves 406 can guide lifting plate 401 and prevent lifting plate 401 from tilting. Lifting plate 401 can transmit pressure to clamping plate 2 through compression spring 404. When clamping plate 2 clamps the frame of photovoltaic module, compression spring 404 is in a compressed state, which can provide pre-tightening force and reduce pressure fluctuation, and clamping plate 2 is not easy to loosen.

[0026] In this embodiment, preferably, the self-locking mechanism 6 includes a pawl 601, which is engaged with a ratchet 5. A rotating shaft 602 is fixedly provided at the bottom end of the pawl 601. The rotating shaft 602 is rotatably connected to the top end of the clamping frame 1. A torsion spring 603 is sleeved on the surface of the rotating shaft 602. One side of the torsion spring 603 is engaged with the pawl 601, and the other side of the torsion spring 603 is engaged with a baffle 604. The bottom end of the baffle 604 is fixedly connected to the top end of the clamping frame 1. When the screw 3 is rotated by the knob 7, the pawl 601 and the ratchet 5 can ensure the unidirectional rotation of the screw 3. After the rotation is completed, under the support of the torsion spring 603, the pawl 601 and the ratchet 5 are engaged, which can prevent the screw 3 from retracting and can play a self-locking role.

[0027] In this embodiment, preferably, the top of the lead screw 3 is rotatably connected to the middle of the top of the clamping frame 1, and the bottom of the lead screw 3 is rotatably connected to a support 13. The support 13 is fixedly connected to the inside of the clamping frame 1. A second rubber pad 11 is bonded to the inner wall of the bottom end of the clamping frame 1. The surfaces of the first rubber pad 10 and the second rubber pad 11 are coated with an anti-aging agent. The support 13 can provide support to the bottom end of the lead screw 3. The second rubber pad 11 and the first rubber pad 10 cooperate to ensure the fit and friction of the clamping surface.

[0028] In this embodiment, preferably, the top end of the protective cylinder 9 is provided with a groove, and a sealing gasket 14 is engaged inside the groove. The top end of the protective cylinder 9 is fixedly installed with a protective cover 15 by screws. The sealing gasket 14 can seal the protective cover 15, preventing rainwater from seeping in during rainy weather.

[0029] In use, the clamping frame 1 is straddled on the frames of two adjacent photovoltaic modules, and the two clamping plates 2 are respectively located on the frames of the two sets of photovoltaic modules. Then, the screw 3 is rotated by the knob 7. If necessary, the knob 7 can be rotated by the wrench position 8. The nut of the elastic pressure mechanism 4 can convert the rotational motion of the screw 3 into the linear motion of the lifting plate 401. The guide post 12 and the column groove 406 can guide the lifting plate 401 and prevent the lifting plate 401 from tilting. The lifting plate 401 can transmit pressure to the clamping plate 2 through the compression spring 404. When the clamping plate 2 clamps the frame of the photovoltaic module, the compression spring 404 is in a compressed state, which can provide pre-tightening force and reduce pressure fluctuation. The clamping plate 2 is not easy to loosen. The setting of rubber pad 2 11 and rubber pad 10 can ensure the fit and friction of the clamping surface, which can reinforce the two sets of photovoltaic modules and effectively restrain the up-and-down shaking and front-and-back displacement of the photovoltaic modules under wind load.

[0030] When the screw 3 is rotated by the knob 7, the pawl 601 and ratchet 5 of the self-locking mechanism 6 can ensure the unidirectional rotation of the screw 3. After the rotation is completed, under the support of the torsion spring 603, the pawl 601 and ratchet 5 engage, which can prevent the screw 3 from retracting and play a self-locking role. After the photovoltaic module is reinforced, the protective cover 15 is fixed to the protective cylinder 9 by screws, which can provide shielding protection for the knob 7 and the self-locking mechanism 6. The sealing gasket 14 can seal the protective cover 15 and prevent rainwater from seeping in during rainy weather.
