Description

Technical Field

[0001] This utility model relates to the field of photovoltaic panel clamping block loosening detection technology, and in particular to a photovoltaic panel clamping block loosening detection device. Background Technology

[0002] A photovoltaic module refers to the smallest indivisible photovoltaic cell assembly that is encapsulated and internally connected and can provide DC power output independently. It is composed of solar cells or solar cells of different specifications cut by laser cutting machines or wire cutting machines. The photovoltaic cell is the most important and basic power generation unit of a photovoltaic module. Therefore, the quality of a photovoltaic module largely depends on the quality of the photovoltaic cells.

[0003] In photovoltaic (PV) power generation systems, pressure blocks play a role in installing and fixing solar panels. As the most important part of the PV system, the PV support structure requires the support of accessories to achieve good stability. Among these accessories, pressure blocks are important auxiliary accessories. Pressure blocks fix the module support structure, prevent the support structure from shifting, and ensure the stability of the module installation. In existing technologies, pressure blocks use bolts to press and fix the PV modules. However, after the pressure blocks are installed, the PV panels are usually manually pulled to test whether the installation is stable. This manual testing method requires pulling the PV panels, and the pulling force is difficult to control, which can easily damage the PV panels. Moreover, the test is completed by feel and visual inspection, which has poor accuracy. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as difficulty in controlling the tensile force, which can easily damage photovoltaic panels, and the poor accuracy of testing based on touch and visual inspection. This invention provides a photovoltaic panel clamp loosening detection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic panel clamping block loosening detection device, comprising a placement frame, a sliding rod fixedly connected to the outer surface of the placement frame, a fixing frame fixedly connected to the outer surface of the placement frame, a first motor fixedly connected to the outer surface of the fixing frame, a screw fixedly connected to one end of the first motor, a slot sleeved on the outer surface of the sliding rod, a limit rod fixedly connected to the outer surface of the fixing frame, a collar sleeved on the outer surface of the screw, a connecting rod fixedly connected to one side of the collar, an adjusting frame fixedly connected to the outer surface of the connecting rod, a movable plate sleeved on the inner wall of the adjusting frame, and a movable block fixedly connected to the outer surface of the movable plate.

[0006] In a preferred embodiment, a second motor is fixedly connected to the outer surface of the adjustment frame, and a bidirectional lead screw is fixedly connected to one end of the second motor.

[0007] In a preferred embodiment, the outer surface of the bidirectional lead screw penetrates the inner wall of the moving plate, and the bidirectional lead screw is threadedly connected to the inner wall of the moving plate.

[0008] In a preferred embodiment, the outer surface of the placement rack is provided with a scale, and a pointer is fixedly connected to the outer surface of the slot.

[0009] In a preferred embodiment, the outer surface of the slot has a through hole, the outer surface of the slide rod is slidably connected to the inner wall of the through hole, a photovoltaic panel is sleeved on the slot, and a pressure block assembly is connected to the outer surface of the photovoltaic panel.

[0010] In a preferred embodiment, the outer surface of the collar is provided with a threaded hole, and the outer surface of the screw is threadedly connected to the inner wall of the threaded hole.

[0011] In a preferred embodiment, the inner wall of the collar is provided with a sliding hole, and the outer surface of the limiting rod is slidably connected to the inner wall of the sliding hole.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: This utility model provides an installation environment for other components by setting up a placement rack, making it convenient for workers to install photovoltaic panels and thus facilitating the inspection of the pressure block assembly. A sliding rod ensures the slot can move normally while preventing it from falling off. After the photovoltaic panel and pressure block assembly are connected, the slot is moved so that the gap between the two photovoltaic panels is directly below the moving block. Then, a first motor drives a screw to rotate, which moves the collar. A limit rod guides the collar during its movement, preventing it from rotating. The movement of the collar also moves the connecting rod, which in turn moves the adjusting frame. Attached Figure Description

[0019] 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.

[0020] Example 1 like Figures 1-5 As shown, this utility model provides a technical solution: a photovoltaic panel pressing block loosening detection device, including a placement frame 1, a sliding rod 2 fixedly connected to the outer surface of the placement frame 1, a fixing frame 3 fixedly connected to the outer surface of the placement frame 1, a first motor 5 fixedly connected to the outer surface of the fixing frame 3, a screw 8 fixedly connected to one end of the first motor 5, a slot 4 sleeved on the outer surface of the sliding rod 2, a limit rod 9 fixedly connected to the outer surface of the fixing frame 3, a collar 7 sleeved on the outer surface of the screw 8, a connecting rod 10 fixedly connected to one side of the collar 7, a photovoltaic panel sleeved on the inner wall of the slot 4, and a pressing block assembly 6 connected to the outer surface of the photovoltaic panel.

[0021] In this embodiment, the placement rack 1 provides an installation environment for other components and facilitates the installation of photovoltaic panels by staff, thereby facilitating the inspection of the pressure block assembly 6. The sliding rod 2 ensures that the slot 4 can move normally while preventing it from falling off. After the photovoltaic panel and the pressure block assembly 6 are connected, the slot 4 is moved so that the gap between the two photovoltaic panels is directly below the moving block 15. Then, the first motor 5 drives the screw 8 to rotate, and the rotation of the screw 8 causes the collar 7 to move. The limiting rod 9 ensures that the collar 7 moves while guiding it, preventing it from rotating. As the collar 7 moves, it drives the connecting rod 10 to move, which in turn drives the adjusting frame 11 to move.

[0022] Example 2 like Figures 1-5As shown, an adjusting frame 11 is fixedly connected to the outer surface of the connecting rod 10. A moving plate 14 is sleeved on the inner wall of the adjusting frame 11. A moving block 15 is fixedly connected to the outer surface of the moving plate 14. A second motor 12 is fixedly connected to the outer surface of the adjusting frame 11. A bidirectional lead screw 13 is fixedly connected to one end of the second motor 12. The outer surface of the bidirectional lead screw 13 penetrates the inner wall of the moving plate 14. The bidirectional lead screw 13 is threadedly connected to the inner wall of the moving plate 14. The outer surface of the placement frame 1 is provided with a scale 16. A pointer 17 is fixedly connected to the outer surface of the slot 4.

[0023] In this embodiment, when the adjusting frame 11 moves, the surface of the moving block 15 is brought into contact with the surface of the photovoltaic panel. Then, the second motor 12 drives the bidirectional lead screw 13 to rotate. Since the moving plate 14 is threadedly connected to the bidirectional lead screw 13, the two moving plates 14 move in opposite directions while the bidirectional lead screw 13 rotates, which in turn drives the moving block 15 to move. The movement of the moving block 15 causes the photovoltaic panel to move to both sides, which in turn causes the slot 4 to move. The movement of the slot 4 causes the pointer 17 to move, and the distance extended by the pointer 17 can be read and recorded by the exposure degree of the scale 16. When the tightness of the pressure block assembly 6 is up to standard, the moving block 15 cannot push the photovoltaic panel, that is, the photovoltaic panel cannot push the slot 4, and the scale 16 cannot be read and recorded.

[0024] Working principle: like Figures 1-5 As shown, in this utility model, when the operator needs to inspect the pressing block assembly 6, firstly, the photovoltaic panel is connected to the slot 4, and then the pressing block assembly 6 is connected to the photovoltaic panel. After the connection is completed, the slot 4 is moved so that the gap between the two photovoltaic panels is directly below the moving block 15. Then, the first motor 5 drives the screw 8 to rotate, and the rotation of the screw 8 causes the collar 7 to move. The limiting rod 9 ensures that the collar 7 moves while guiding it, ensuring that the collar 7 does not rotate. Then, the collar 7 moves while driving the connecting rod 10 to move, thereby driving the adjusting frame 11 to move. When the adjusting frame 11 moves, the surface of the moving block 15 is adjusted. The surface of the pressure block assembly 6 is attached to the surface of the photovoltaic panel. Then, the second motor 12 drives the bidirectional lead screw 13 to rotate. Since the moving plate 14 is threadedly connected to the bidirectional lead screw 13, the two moving plates 14 move in opposite directions while the bidirectional lead screw 13 rotates. This drives the moving block 15 to move. The movement of the moving block 15 causes the photovoltaic panel to move to both sides, which in turn causes the slot 4 to move. The movement of the slot 4 causes the pointer 17 to move. The distance that the pointer 17 moves can be read and recorded by the exposure degree of the scale 16. When the tightness of the pressure block assembly 6 is up to standard, the moving block 15 cannot push the photovoltaic panel, that is, the photovoltaic panel cannot push the slot 4, and the scale 16 cannot be read and recorded.

[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
