Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic module transportation, and particularly relates to a lifting device for photovoltaic modules with a protection function. Background Technique

[0002] Photovoltaic modules generally refer to solar cell modules. Only after several single cells are connected in series and parallel and encapsulated into modules can they be used as power sources. Photovoltaic modules are the most important part of a solar power generation system, which can convert solar energy in nature into electrical energy and store the electrical energy.

[0003] However, at present, when installing photovoltaic modules, they need to be transported. The lifting devices used in the transportation process lack the limit protection function for photovoltaic modules. If the modules slide, it is easy to cause injuries to workers and damage to property. Moreover, the lifting devices used have low transportation efficiency and slow down the working process of module installation. Therefore, we propose a lifting device for photovoltaic modules with a protection function to solve the problems mentioned above. Content of the Utility Model

[0004] The utility model aims to provide a lifting device for photovoltaic modules with a protection function to solve the problem that the existing lifting devices for photovoltaic modules cannot provide limit protection for photovoltaic modules.

[0005] A lifting device for photovoltaic modules with a protection function in this solution includes a bracket. Two vertical plates are fixedly connected to the bracket. A lifting mechanism is arranged between the two vertical plates. The lifting mechanism is connected with a plurality of support plates for placing photovoltaic modules. A protection component for protecting the photovoltaic modules and a limit component for limiting the photovoltaic modules on the support plates are arranged on the support plates.

[0006] The working principle and beneficial effects of this solution: When in use, place the photovoltaic module on the support plate, use the protection component to clamp and protect the protection component, protect both sides of the photovoltaic module, and then use the limit component to limit the four sides of the photovoltaic module on the support plate to ensure that the photovoltaic module is limited on the support plate, and then use the lifting mechanism to lift and lower. Since the lifting device in this solution is provided with a protection component to clamp and protect both sides of the photovoltaic module, and then under the action of the limit component, the photovoltaic module is limited, so as to achieve the function of limiting and protecting the photovoltaic module and avoid injuries to personnel or damage to property caused by the sliding of the photovoltaic module.

[0007] Further, the lifting mechanism includes a chain and two sprockets. Two mounting shafts are rotatably connected between the two vertical plates. The two sprockets are fixedly connected to the mounting shafts. The two sprockets are driven by the chain. One of the sprockets is connected with a driver. The driver drives one of the sprockets to rotate, drives the two sprockets to rotate together through the chain, and thus drives the chain to move in a uniform circular motion.

[0008] Furthermore, the driver includes a first motor fixed on the bracket. The output shaft of the first motor is fixedly connected with a driving bevel gear, which meshes with a driven bevel gear. The driven bevel gear is fixedly connected with the mounting shaft. The first motor drives the driving bevel gear to rotate, the driving bevel gear drives the driven bevel gear to rotate, the driven bevel gear drives the mounting shaft to rotate, and the mounting shaft drives the sprocket to rotate, thereby driving the chain to lift and lower.

[0009] Furthermore, a cavity is provided on the support plate. The protection assembly includes two connecting plates located on both sides of the support plate. On one side of the two connecting plates adjacent to each other, racks are fixedly connected. A gear meshes between the two racks. The gear is connected with a second motor for driving it to rotate. The second motor, the gear and the two racks are all located in the cavity. Both ends of the cavity penetrate through the support plate for the connecting plates to slide. When the second motor is turned on, the second motor drives the gear to rotate, driving the two racks to move horizontally towards each other or in the opposite direction, thereby driving the connecting plates to approach and clamp the photovoltaic module, or loosen the photovoltaic module in the opposite direction. The provision of the cavity facilitates the operation of the gear and the rack and will not affect the movement of the gear and the rack after the photovoltaic module is placed.

[0010] Furthermore, the limiting assembly includes two fixing rods fixedly connected to the support plate. An electric telescopic rod and a blocking rod are respectively rotatably connected to the fixing rods. The electric telescopic rod is connected to the middle of the blocking rod. By controlling the electric telescopic rod, the two blocking rods are driven to incline in the opposite direction. At this time, the tops of the two blocking rods approach each other, and the two blocking rods and the support plate form a triangle, thereby limiting the photovoltaic module from the side.

[0011] Furthermore, one end of the electric telescopic rod is fixedly connected with a first connecting block, and the other end of the electric telescopic rod is rotatably connected with a second connecting block. The first connecting block is rotatably connected with the fixing rod, and the second connecting block is fixedly connected with the blocking rod. This setting can strengthen the connection of the electric telescopic rod. Description of the Drawings

Two mounting shafts 5 are rotatably connected between the two vertical plates 2, and the two sprockets 6 are fixedly connected to the mounting shafts 5. One of the mounting shafts 5 is fixedly connected with a driven bevel gear 19, the driven bevel gear 19 meshes with a driving bevel gear 20, the driving bevel gear 20 is connected with a first motor 3 that drives it to rotate, the first motor 3 is fixed on the bracket 1, the two sprockets 6 are driven by the chain 7, and a plurality of support plates 8 are arranged side by side on the outer side of the chain 7.

[0020] A protection component and two limiting components are provided on each of the support plates 8;

[0021] A cavity is provided on the support plate 8. The protection component includes two connecting plates 13 located on both sides of the support plate 8. The connecting plates 13 are fixedly connected with sliding blocks 12. A rack 11 is fixedly connected to one side of the two adjacent sliding blocks 12. A gear 10 meshes between the two racks 11. The gear 10 is connected with a second motor 9 that drives it to rotate. The second motor 9, the gear 10 and the two racks 11 are all located in the cavity. The sliding blocks 12 and the two racks 11 are slidably connected in the cavity, and both ends of the cavity penetrate upward through the support plate 8 for the connecting plates 13 to slide;

[0022] The limiting component includes two fixed rods 14 fixedly connected to the support plate 8. A stop rod 18 is rotatably connected to the lower end of the fixed rod 14. A second connecting block 17 is fixedly connected to the middle of the stop rod 18. A first connecting block 16 is rotatably connected to the upper end of the fixed rod 14.

[0023] During use, place the photovoltaic module between the two connecting plates 13 of the support plate 8. Turn on the second motor 9, which drives the gear 10 to rotate, driving the two racks 11 to move horizontally towards each other. The movement of the racks 11 drives the sliding blocks 12 to move, thereby driving the connecting plates 13 to move closer to clamp the photovoltaic module. Control the electric telescopic rod 15 to drive the tops of the two blocking rods 18 to tilt towards the middle of the support plate 8. At this time, the tops of the two blocking rods 18 approach each other, and the two blocking rods 18 and the support plate 8 form a triangle, which is a more stable structure. The blocking rods 18 limit the photovoltaic module from the side. The fixing rod 14 and the connecting plate 13 form a rectangle to protect the four sides of the photovoltaic module. Turn on the first motor 3, which drives the driving bevel gear 20 to rotate. The driving bevel gear 20 drives the driven bevel gear 19 to rotate. The driven bevel gear 19 drives the mounting shaft 5 to rotate. The mounting shaft 5 drives the sprocket 6 to rotate, thereby driving the chain 7 to lift and lower. Through the lifting and lowering of the chain 7, the support plate 8 is driven to lift and lower. The end of the chain 7 that moves upward rises, driving the support plate 8 to rise. After moving to the top, remove the photovoltaic module. Then, as the chain 7 moves, the protection component and the limiting component on the support plate 8 are both located below the support plate 8, and the debris on the support plate 8 can also fall off, which can keep the surface of the support plate 8 clean.

[0024] Use the protection component to clamp and protect the photovoltaic module on both sides, and then use the limiting component to limit the four sides of the photovoltaic module on the support plate 8 to ensure that the photovoltaic module is limited on the support plate 8, and then use the lifting mechanism to lift and lower.
