Description

Technical Field

[0001] This invention belongs to the field of solar photovoltaic panel technology, and specifically relates to a mounting bracket for a solar photovoltaic panel. Background Technology

[0002] With the continued growth in global demand for renewable energy, solar photovoltaic power generation, as a clean and efficient energy utilization method, has been widely used. Solar photovoltaic panels typically need to be installed outdoors, and the stability of their fixing and mounting brackets directly affects the safe operation and power generation efficiency of the photovoltaic system.

[0003] Common photovoltaic (PV) panel mounting brackets often employ bolt locking or clip-on fixing methods. These structures suffer from drawbacks in practice, including cumbersome installation steps, difficulty in alignment, and the tendency for clamping force to loosen due to vibration or wind load. Consequently, during long-term outdoor use, bolts may fail due to corrosion or vibration, and clip-on structures may lose stable clamping force due to manufacturing tolerances or material aging, leading to PV panel displacement or even detachment, posing significant safety hazards. Furthermore, the long-term exposure of solar PV panels to air makes their surfaces prone to accumulating dust, bird droppings, leaves, and other pollutants, significantly reducing light transmittance and photoelectric conversion efficiency. Currently, cleaning PV panel surfaces mainly relies on regular manual cleaning or the installation of automated cleaning robots. However, these methods are costly, complex to maintain, and unsuitable for large-scale or remote PV power plants. Therefore, those skilled in the art have developed a solar PV panel mounting bracket to address the problems mentioned in the background section. Summary of the Invention

[0004] The purpose of this invention is to provide a simple and reasonably designed mounting bracket for solar photovoltaic panels in order to solve the above-mentioned problems.

[0005] The present invention achieves the above objectives through the following technical solutions: A mounting bracket for a solar photovoltaic panel includes a fixed plate and two clamping devices. A support rod is fixedly connected to the top center of the fixed plate, and an angle adjustment mechanism is provided on the side wall of the support rod. The two clamping devices include second fixed frames, one of which has a second fixed rod fixedly connected to the center, and the other has a first fixed rod fixedly connected to the center. Both the second and first fixed rods cooperate with the angle adjustment mechanism. A limit device is provided between the two second fixed frames.

[0007] As a further optimization of the present invention, the angle adjustment mechanism includes a second connecting sleeve that is movably connected to the side wall of the support rod. The inner wall of the second connecting sleeve is threaded with a second screw that is rotatably connected to the bottom end of the side wall of the first fixed rod. The top end of the support rod is fixedly connected to a first mounting bracket. The inner wall of the first mounting bracket is rotatably connected to a first rotating block. The middle of the first rotating block rotatably passes through a second fixed rod. An adjustment module is provided on the side wall of the first rotating block.

[0008] As a further optimization of the present invention, the adjustment module includes a second rotating block fixedly sleeved to one end of the second fixed rod, a first screw rotatably connected to the side wall of the second rotating block, a connecting frame fixedly connected to the side wall of the support rod, and a first connecting sleeve threadedly connected to the first screw movably connected to the top of the connecting frame.

[0009] As a further optimization of the present invention, the rotating device includes a rack fixedly connected to both sides of the insertion rod, a first fixed frame fixedly connected to both sides of the slide, a gear meshing with the rack being rotatably connected to the inner wall of the first fixed frame, and a rotating rod being fixedly sleeved at both ends of the fixed shaft in the middle of the gear.

[0010] As a further optimization of the present invention, the clamping device further includes a slide rod that is slidably connected to the top of the inner wall of the second fixed frame. The side wall of the slide rod is slidably sleeved with the rotating rod. A connecting rod is fixedly sleeved in the middle of the slide rod, and a clamping mechanism is provided at one end of the connecting rod.

[0011] As a further optimization of the present invention, the clamping mechanism includes two second limiting rods that slide through one end of the connecting rod, one end of the two second limiting rods is fixedly connected to a clamping plate, and the sidewalls of the second limiting rods are respectively sleeved with second springs fixedly connected to the clamping plates. The top end of the clamping plate is rotatably connected to a plurality of positioning plates, and the bottom end of the plurality of positioning plates is fixedly connected to a top rod.

[0012] As a further optimization of the present invention, the fixing device includes a mounting base fixedly connected to the top end of the insertion rod, a fixing shell fixedly connected to the front end and the rear end of the mounting base, and a bidirectional lead screw rotatably connected to the inner walls of the two fixing shells. The two ends of the bidirectional lead screw are respectively threaded with sliders that are slidably connected to the inner walls of the fixing shells. A film-releasing clamping seat is provided on the side wall of the two sliders located on the inner wall of one of the fixing shells, and a film-receiving clamping seat is provided on the side wall of the two sliders located on the inner wall of the other fixing shell.

[0013] As a further optimization of the present invention, the film-releasing clamping seat includes a first rotating shaft that slides through the side wall of the slider, a fixing ring is fixedly sleeved on the side wall of the first rotating shaft, a first clamping block is rotatably sleeved on one end of the fixing ring, and a third spring is sleeved on the side wall of the first rotating shaft and fixedly connected to the fixing ring.

[0014] As a further optimization of the present invention, the film receiving clamping seat includes a second rotating shaft that rotates through the slider, a second clamping block that is rotatably connected to the side wall of one of the sliders is rotatably sleeved at one end of the second rotating shaft, a worm wheel that is fixedly sleeved on the side wall of one of the second rotating shafts, and a worm that meshes with the worm wheel that is rotatably connected to the side wall of one of the sliders.

[0015] The beneficial effects of this invention are as follows: 1. In this invention, by setting a limiting device and a rotating device, after the solar photovoltaic panel is placed on the fixing device, pressing the insertion rod can cause the insertion rod to move downward along the slide. Since the front end of the insertion rod is provided with a first ratchet, as the first ratchet moves downward, and with the cooperation of the second ratchet and the first ratchet, the insertion rod can move downward, so that the clamping device will not loosen after fixing the photovoltaic panel. During the movement of the insertion rod, the rack will move downward synchronously. At this time, the rack will drive the gear to rotate. As the gear rotates, the rotating rod will deflect with the rotation of the gear, effectively driving the clamping device to clamp the photovoltaic panel, effectively preventing loosening after the insertion rod moves to the designated position, thereby improving the stability of fixing the photovoltaic panel.

[0016] 2. In this invention, by setting up a clamping device, during the rotation of the rotating rod, the sliding rod will be driven to slide in the second fixed frame, thereby pushing the connecting rod to slide along the inner wall of the second fixed frame, so that the top rod on the clamping plate can contact the side wall of the photovoltaic panel and rotate on the clamping plate. At this time, the positioning plate rotates synchronously and overlaps the top of both sides of the photovoltaic panel to achieve clamping and fixing of the photovoltaic panel. Furthermore, the positioning plate limits the upper surface of the photovoltaic panel, which can effectively prevent the photovoltaic panel from falling off from above and improve the stability during installation.

[0017] 3. In this invention, by setting a fixing device, the photovoltaic panel can be initially positioned using the groove in the middle of the mounting base. After the clamping device installs the photovoltaic panel, a transparent film roll that matches the width of the photovoltaic panel can be selected. At this time, the bidirectional lead screw is rotated so that the slider on the bidirectional lead screw matches the length of the transparent film roll. The film-releasing clamping seat clamps the hollow roller in the middle of the film roll to fix the film roll. After the film roll passes over the photovoltaic panel, the film-receiving clamping seat on another fixing shell is used to install the hollow roller that collects the transparent film. By rotating the film-receiving clamping seat, a new transparent film can be replaced when the transparent film is covered with dust, effectively avoiding the impact of dust on the photovoltaic's reception of sunlight and improving power generation efficiency.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Example: Figure 1 , Figure 2 , Figure 12 and Figure 14 As shown, a mounting bracket for a solar photovoltaic panel includes a fixing plate 5 and two clamping devices 3. A support rod 6 is fixedly connected to the top center of the fixing plate 5. The two clamping devices 3 include second fixing frames 301. A second fixing rod 16 is fixedly connected to the middle of one second fixing frame 301, and a first fixing rod 12 is fixedly connected to the middle of the other second fixing frame 301. A limiting device 1 is provided between the two second fixing frames 301. A fixing device 4 is provided at the top of the limiting device 1. Rotating devices 2 that cooperate with the clamping devices 3 are respectively provided on both sides of the limiting device 1.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 13 and Figure 15As shown, the limiting device 1 includes a slide 105 fixedly connected to two second fixed frames 301. A rod 101 is slidably connected to the middle of the slide 105. A first ratchet rack 102 is fixedly connected to the front end of the rod 101. An adjusting frame 104 is fixedly connected to the front end of the slide 105. A first limiting rod 103 slidably passes through the front end of the adjusting frame 104. A second ratchet rack 107 cooperating with the first ratchet rack 102 is fixedly connected to one end of the first limiting rod 103. A first spring 106 fixedly connected to the front end of the second ratchet rack 107 is sleeved on the side wall of the first limiting rod 103. The first limiting rod 103 is slidably mounted on the adjusting frame 104, and the first spring 106 is sleeved on the side wall of the first limiting rod 103 to ensure… The second ratchet 107 and the first ratchet 102 are always engaged under the elastic force of the first spring 106 to prevent the insertion rod 101 from loosening. The engagement of the second ratchet 107 with the insertion rod 101 can be released by pulling the first limiting rod 103. After the solar photovoltaic panel is placed on the fixing device 4, pressing the insertion rod 101 can make the insertion rod 101 move downward along the slide 105. Since the front end of the insertion rod 101 is provided with the first ratchet 102, as the first ratchet 102 moves downward, and with the engagement of the second ratchet 107 with the first ratchet 102, the insertion rod 101 can move downward, so that the clamping device 3 will not loosen after fixing the photovoltaic panel.

[0023] like Figure 1 , Figure 12 and Figure 14 As shown, a second connecting sleeve 10 is movably connected to the side wall of the support rod 6. A second screw 11, which is rotatably connected to the bottom end of the side wall of the first fixed rod 12, is threaded onto the inner wall of the second connecting sleeve 10. A first mounting bracket 7 is fixedly connected to the top of the support rod 6. A first rotating block 13 is rotatably connected to the inner wall of the first mounting bracket 7. A second fixed rod 16 is rotatably passed through the middle of the first rotating block 13. After the photovoltaic panel is installed, the combined distance between the second connecting sleeve 10 and the second screw 11 can be adjusted by rotating the second connecting sleeve 10, so that the second fixed rod 16 can rotate around the first mounting bracket 7, thereby adjusting the angle of the photovoltaic panel in the horizontal direction.

[0024] like Figure 1 , Figure 12 and Figure 14As shown, a second rotating block 14 is fixedly sleeved on one end of the second fixed rod 16. The connection between the second fixed rod 16 and the second rotating block 14 is a spline rod, which can better drive the second fixed rod 16 to rotate synchronously when the second rotating block 14 rotates. A first screw 15 is rotatably connected to the side wall of the second rotating block 14. A connecting frame 8 is fixedly connected to the side wall of the support rod 6. A first connecting sleeve 9, which is threaded to the first screw 15, is movably connected to the top of the connecting frame 8. By rotating the first connecting sleeve 9, the distance between the first connecting sleeve 9 and the first screw 15 can be adjusted. The second fixed rod 16 can be driven to rotate axially by the second rotating block 14, thereby realizing the adjustment of the angle of the photovoltaic panel in the front and rear directions.

[0025] like Figure 1 - Figure 5 As shown, the rotating device 2 includes a rack 202 fixedly connected to both sides of the insertion rod 101, and a first fixing frame 201 fixedly connected to both sides of the slide 105. A gear 203 meshing with the rack 202 is rotatably connected to the inner wall of the first fixing frame 201. Rotating rods 204 are fixedly sleeved at both ends of the fixed shaft in the middle of the gear 203. During the movement of the insertion rod 101, the rack 202 will move downward synchronously. At this time, the rack 202 will drive the gear 203 to rotate. As the gear 203 rotates, the rotating rod 204 will deflect along with the rotation of the gear 203, effectively driving the clamping device 3 to clamp the photovoltaic panel, effectively preventing loosening after the insertion rod 101 moves to the designated position, thereby improving the stability of fixing the photovoltaic panel.

[0026] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12 As shown, the clamping device 3 also includes a slide rod 303 that is slidably connected to the top of the inner wall of the second fixed frame 301. A sliding groove is provided on the side wall of the rotating rod 204 to slide in cooperation with the side wall of the slide rod 303. When the rotating rod 204 rotates around the fixed shaft in the middle of the gear 203, it drives the slide rod 303 to slide in the inner wall of the second fixed frame 301, thereby clamping the photovoltaic panel. The side wall of the slide rod 303 is slidably sleeved with the rotating rod 204. A connecting rod 302 is fixedly sleeved in the middle of the slide rod 303. During the rotation of the rotating rod 204, the slide rod 303 will slide in the second fixed frame 301, thereby pushing the connecting rod 302 to slide along the inner wall of the second fixed frame 301.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 12 As shown, one end of the connecting rod 302 slides through two second limiting rods 304. One end of each second limiting rod 304 is fixedly connected to a clamping plate 306. Second springs 305, fixedly connected to the clamping plates 306, are respectively sleeved on the side walls of the second limiting rods 304. The clamping plates 306 also have second limiting rods 304 that slide through the connecting rod 302 on their side walls, and second springs 305 on the side walls of the second limiting rods 304. This ensures that the clamping plate 306 flexibly clamps the photovoltaic panel's sidewall, preventing damage to the photovoltaic panel during clamping. To prevent damage, the top of the clamping plate 306 is rotatably connected to several positioning plates 307, and the bottom of the positioning plates 307 is fixedly connected to top rods 308. The top rods 308 on the clamping plate 306 can contact the side wall of the photovoltaic panel, allowing it to rotate on the clamping plate 306. At this time, the positioning plates 307 rotate synchronously, overlapping the tops of both sides of the photovoltaic panel to clamp and fix the photovoltaic panel. Furthermore, the positioning plates 307 limit the upper surface of the photovoltaic panel, which can effectively prevent the photovoltaic panel from coming off from above and improve the stability during installation.

[0028] like Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the fixing device 4 includes a mounting base 401 fixedly connected to the top end of the insertion rod 101. A fixing shell 402 is fixedly connected to the front and rear ends of the mounting base 401, respectively. A bidirectional lead screw 406 is rotatably connected to the inner walls of the two fixing shells 402. Slider blocks 403, which are slidably connected to the inner walls of the fixing shells 402, are threaded onto both ends of the bidirectional lead screw 406. A film-laying clamping seat 404 is provided on the side walls of the two sliders 403 located on the inner wall of one fixing shell 402, and a film-retracting clamping seat 405 is provided on the side walls of the two sliders 403 located on the inner wall of the other fixing shell 402. The groove in the middle of the mounting base 401 allows for initial confinement of the photovoltaic panel. After the photovoltaic panels are installed using the clamping device 3, a transparent film roll that matches the width of the photovoltaic panels can be selected. At this time, the bidirectional lead screw 406 is rotated so that the slider 403 on the bidirectional lead screw 406 matches the length of the transparent film roll. The film unloading clamping seat 404 clamps the hollow roller in the middle of the film roll to fix the film roll. After the film roll passes over the photovoltaic panels, the film receiving clamping seat 405 on another fixing shell 402 is used to install the hollow roller that collects the transparent film. By rotating the film receiving clamping seat 405, a new transparent film can be replaced when the transparent film is covered with dust, effectively avoiding the impact of dust on the photovoltaic's reception of sunlight and improving power generation efficiency.

[0029] like Figure 1 , Figure 2, Figure 3 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the film-laying clamping seat 404 includes a first rotating shaft 4041 that slides through the side wall of the slider 403. A fixing ring 4043 is fixedly sleeved on the side wall of the first rotating shaft 4041. A first clamping block 4044 is rotatably sleeved on one end of the fixing ring 4043. A third spring 4042 is sleeved on the side wall of the first rotating shaft 4041 and fixedly connected to the fixing ring 4043. The film-laying clamping seat 404 is provided with the first rotating shaft 4041 and the third spring 4042. The pressure applied by the third spring 4042 to the fixing ring 4043 can ensure the stability of the transparent film roll when clamping it and prevent it from falling.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, the film collection clamping base 405 includes a second rotating shaft 4053 that rotatably passes through the slider 403. One end of the second rotating shaft 4053 is rotatably fitted with a second clamping block 4051 rotatably connected to the side wall of one of the sliders 403. A worm gear 4052 is fixedly fitted to the side wall of one of the second rotating shafts 4053. A worm 4054, meshing with the worm gear 4052, is rotatably connected to the side wall of one of the sliders 403. The worm gear 4052 is located on the side wall of one of the second rotating shafts 4053 in the film collection clamping base 405, and is driven to rotate by the worm 4054. This allows for the recovery of the laid transparent film, ensuring the light... The surface of the photovoltaic panel can receive good sunlight. A rollable and replaceable transparent film is laid on the surface of the photovoltaic panel. Because the glass on the surface of the photovoltaic panel generates static electricity during the power generation process, it can firmly attract fine dust in the air to the surface of the photovoltaic panel. In addition, dew, fog and even rainwater will cause the dust to mix with water vapor and form a thin mud film on the panel, forming an oily film that makes it difficult to clean the surface of the photovoltaic panel with a brush. Using a transparent film to shield and protect the surface of the photovoltaic panel can prevent dust from falling directly on the surface of the photovoltaic panel without affecting the sunlight conditions, thereby avoiding the impact on the power generation efficiency of the photovoltaic panel.

[0031] It should be noted that, in use, the mounting bracket for this type of solar photovoltaic panel utilizes the groove in the middle of the mounting base 401 to initially limit the position of the photovoltaic panel. After the clamping device 3 installs the photovoltaic panel, a transparent film roll that matches the width of the photovoltaic panel can be selected. At this time, the bidirectional lead screw 406 is rotated so that the slider 403 on the bidirectional lead screw 406 matches the length of the transparent film roll, and the film-releasing clamping seat 404 clamps the hollow roller in the middle of the film roll to fix the film roll. After the film roll passes over the photovoltaic panel, the film-receiving clamping seat 405 on another fixing shell 402 is used to install the hollow roller that collects the transparent film. By rotating the film-receiving clamping seat 405, a new transparent film can be replaced when the transparent film is covered with dust. After the solar photovoltaic panel is placed on the fixing device 4, pressing the insertion rod 101 allows the insertion rod 101 to move downward along the slide 105. Since the front end of the insertion rod 101 is provided with a first ratchet, As the first ratchet 102 moves downward, and with the cooperation of the second ratchet 107 and the first ratchet 102, the insertion rod 101 can move downward, so that the clamping device 3 will not loosen after fixing the photovoltaic panel. During the movement of the insertion rod 101, the rack 202 will move downward synchronously. At this time, the rack 202 will drive the gear 203 to rotate. As the gear 203 rotates, the rotating rod 204 will deflect in accordance with the rotation of the gear 203. By setting the clamping device 3, during the rotation of the rotating rod 204, the sliding rod 303 will slide in the second fixed frame 301, thereby pushing the connecting rod 302 to slide along the inner wall of the second fixed frame 301, so that the top rod 308 on the clamping plate 306 can contact the side wall of the photovoltaic panel and rotate on the clamping plate 306. At this time, the positioning plate 307 rotates synchronously and overlaps the top of both sides of the photovoltaic panel to achieve clamping and fixing of the photovoltaic panel. After the photovoltaic panel is installed, the combined distance between the second connecting sleeve 10 and the second screw 11 can be adjusted by rotating the second connecting sleeve 10, so that the second fixing rod 16 can rotate around the first mounting frame 7, thereby adjusting the angle of the photovoltaic panel in the horizontal direction. At the same time, by rotating the first connecting sleeve 9, the distance between the first connecting sleeve 9 and the first screw 15 can be adjusted. The second fixing rod 16 can be driven to rotate axially by the second rotating block 14, thereby adjusting the angle of the photovoltaic panel in the front-back direction.

[0032] The above-described embodiments are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
