[0002] Under the concept of green development, China is vigorously promoting the development and utilization of renewable energy, and photovoltaic power plants are one of the most representative models. Photovoltaic power plants can achieve uninterrupted power generation throughout the year, make reasonable use of idle land resources, and generate electricity without pollution or noise. They are one of the best systems for converting solar energy into electrical energy.

[0003] Currently, Chinese patent publication number CN210528306U discloses a portable manual lifting device for rooftop photovoltaic power stations, including a support structure, a sleeve, a winch, a lifting assembly, and a horizontal traction rope. The sleeve is vertically installed on the rooftop power station ladder, and the bottom of the support structure is movably installed inside the sleeve. A winch is located in the middle of the support structure, and a lifting assembly is located at the top. One end of the lifting assembly is fixedly stored inside the winch, and the other end is connected to the load to be lifted. A horizontal traction rope is located at the horizontal end of the support structure, and the direction of the support structure is controlled by the horizontal traction rope. This portable manual lifting device reduces maintenance costs and improves the work efficiency of maintenance personnel in the operation and maintenance of distributed rooftop photovoltaic power stations. Furthermore, the lifting device is easy to assemble and disassemble, the lifting direction is easy to control, it has good stability and controllability, is low in cost, lightweight, easy to carry, and convenient to operate, possessing extremely high practical value and cost-effectiveness.

[0004] The above solution uses hooks to directly lift the photovoltaic panels. However, this method cannot secure the photovoltaic panels during use, and the panels will sway during the ascent, potentially colliding with the wall and causing some damage. Therefore, there is an urgent need for a portable manual lifting device for rooftop photovoltaic power stations to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a portable manual lifting device for rooftop photovoltaic power stations to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A portable manual lifting device for a rooftop photovoltaic power station includes a base plate. Two pillars are fixedly connected to the top of the base plate, and a horizontal plate is fixedly connected between the upper ends of the two pillars. A lifting assembly for lifting photovoltaic panels is installed on one side of each pillar, and a fixing mechanism for supporting the photovoltaic panels is provided on one side of the lifting assembly.

[0008] In the above technical solution, the present invention provides a portable manual lifting device for a rooftop photovoltaic power station, (1) using a fixed mechanism to hold the top of the support column against the roof, such as Figure 1 As shown, photovoltaic panels are stacked on top of the moving plate in sequence. The bottom support plate can support the photovoltaic panels when they rise. When the motor is started, the motor drives the two threaded rods to rotate synchronously through the sprocket set. At this time, the long plates approach each other under the restriction of the moving plate, so that photovoltaic panels of different lengths can be fixed. When the screw is rotated, the abutment plate approaches the uppermost photovoltaic panel under the restriction of the guide rod until it is in close contact with the photovoltaic panel, so that the photovoltaic panel can be fixed. (2) Through the set lifting components, the drive motor drives the winch to rotate. The winch winds up the rope. While the rope is winding up, it can pull the moving plate to move upward, so that the photovoltaic panel can be lifted. At the same time, the slider and slide rail can improve the stability of the moving plate when it rises and falls. Attached Figure Description

[0026] The fixing mechanism 3 includes a bottom support plate 30, a motor 31, a sprocket assembly 32, threaded rods 33, a long plate 34, a top plate 35, and a limiting member 36. The bottom support plate 30 is fixedly installed below the surface of the movable plate 28. The motor 31 is fixedly installed on one side of the movable plate 28. The output end of the motor 31 is fixedly installed with the sprocket assembly 32. Two threaded rods 33 are fixedly connected to one side of the sprocket assembly 32. Long plates 34 are threadedly connected to both sides of the surface of the threaded rods 33. The top of the long plate 34 is fixedly connected with... The top plate 35 has a limiting component 36 installed on one side. The limiting component 36 includes a screw 361, an abutment plate 362, and a guide rod 363. The screw 361 is threadedly connected to the middle of the top plate 35. The abutment plate 362 is rotatably installed at one end of the screw 361. The guide rod 363, which is slidably engaged with the top plate 35, is fixedly connected to both sides of the top of the abutment plate 362.

[0027] Specifically, the top of the support column 11 is placed against the roof, such as... Figure 1 As shown, photovoltaic panels are stacked sequentially on top of the movable plate 28. The bottom support plate 30 can support the photovoltaic panels when they rise. When the motor 31 is started, the motor 31 drives the two threaded rods 33 to rotate synchronously through the sprocket set 32. At this time, the long plates 34 approach each other under the restriction of the movable plate 28, which can fix the photovoltaic panels of different lengths.

[0028] Example 2

[0029] This embodiment further defines the lifting assembly 2 based on embodiment 1. The lifting assembly 2 includes a drive motor 21, a winch 22, a rope 23, and a fixed pulley 24. The drive motor 21 is fixedly installed on the top side of the base plate 1. The output end of the drive motor 21 is fixedly installed with the winch 22. The rope 23 is arranged around the outside of the winch 22. The fixed pulley 24 is arranged around the top of the rope 23. The fixed pulley 24 is fixedly connected to the cross plate 12. The lifting assembly 2 also includes a connector 25, a slide rail 26, a slider 27, and a moving plate 28. One end of the rope 23 is tied to the connector 25.

The slide rail 26 is fixedly connected to the upper surface of the support column 11, and its shape matches the support column 11.

[0030] Specifically, the drive motor 21 is started to drive the winch 22 to rotate. The winch 22 winds up the rope 23. While the rope 23 is winding up, it can pull the moving plate 28 upward, thereby lifting the photovoltaic panel. At the same time, the slider 27 and the slide rail 26 can improve the stability of the moving plate 28 when it rises and falls.

[0031] Working principle: When using, first place the top of the support column 11 against the roof, such as... Figure 1 As shown, photovoltaic panels are stacked sequentially on top of the moving plate 28. The bottom support plate 30 supports the photovoltaic panels as they rise. The motor 31 is started, and the motor 31 drives two threaded rods 33 to rotate synchronously through the sprocket set 32. At this time, the long plates 34 move closer to each other under the constraint of the moving plate 28, thus fixing photovoltaic panels of different lengths. When the screw 361 is rotated, the abutment plate 362 moves closer to the uppermost photovoltaic panel under the constraint of the guide rod 363 until it is in close contact with the photovoltaic panel, thus fixing the photovoltaic panel. The drive motor 21 is started to drive the winch 22 to rotate. The winch 22 winds up the rope 23. While the rope 23 is winding up, it can pull the moving plate 28 upward, thus lifting the photovoltaic panels. At the same time, the slider 27 and the slide rail 26 can improve the stability of the moving plate 28 during rising and falling.
