Description

Technical Field

[0001] This utility model relates to the field of guide rail inspection technology, and in particular to a guide rail inspection device for photovoltaic power plants. Background Technology

[0002] Against the backdrop of the accelerated global energy transition, photovoltaic power plants, as an important carrier of clean energy, have placed higher demands on the stability of equipment operation and maintenance efficiency as they develop on a large scale and with intelligence. The guide rail system of photovoltaic power plants, as the core structure supporting photovoltaic modules, is exposed to the outdoor environment for a long time and is prone to accumulating dust, snow, fallen leaves, bird droppings and other debris. It may even rust or deform on the surface of the guide rail due to wind, sand and rain erosion.

[0003] The photovoltaic power station rail-mounted inspection device includes mechanical support, drive movement, detection sensors, control and communication, power supply and auxiliary protection systems. It moves along the rail and detects photovoltaic panel faults through infrared thermal imagers, cameras and other means. After data processing and positioning correlation, the data is uploaded to the background for analysis, fault identification and alarm. It can perform full-coverage, high-precision and stable inspection.

[0004] Existing technologies for rail inspection lack the ability to detect dust, snow, and debris on the rails, which can obstruct the movement of the sliding parts of the inspection device, causing jamming or even stagnation. This disrupts the stable inspection path and speed, affecting inspection efficiency. Debris can also increase friction between the sliding parts and the rail, leading to excessive wear, shortening the device's lifespan, increasing maintenance costs, and causing a decrease in the stability of the mounted detector, resulting in errors in the collected data and affecting the accuracy of the detection. Therefore, a rail-mounted inspection device for photovoltaic power plants is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a guide rail inspection device for photovoltaic power stations, which aims to improve the existing technology where dust, snow, and debris on the track can hinder the sliding of the device, increase maintenance costs, and reduce the stability of the detector, causing data errors that affect the accuracy of the detection.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A guide rail inspection device for a photovoltaic power station includes two sliding frames. Each sliding frame has a sliding plate fixedly connected inside.

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a photovoltaic power station guide rail inspection device, comprising two sliding frames 1, each with a sliding plate 2 fixedly connected inside. Grooves inside the sliding frame 1 provide sliding guide space for the sliding plate 2. Support plates 19 on adjacent sides enhance the connection strength between the frames, ensuring structural stability during device operation. Fixed blocks 3 are fixedly connected to adjacent sides of the sliding plates 2. The bottom of the sliding plate 2 slides in contact with the top of the sliding rail 12, converting the movement of the sliding frame 1 into linear motion along the rail. The outer side of the rotating wheel 10 contacts the top of the fixed block 3. A rotating rod 7 is fixedly connected to the opposite side of the fixed block 3. The pivot point of the rotating rod 7 is fixed on the sliding plate 2, ensuring that the rotating rod 7 swings around the fixed axis point, thereby stably transmitting the tension of the tension spring 5 to the shovel plate 11. The opposite side of the rotating rod 7 is fixedly connected to the adjacent side of the fixed block 3. The adjacent side of the sliding plate 2 is fixedly connected to the fixed rod 6. Through its own structural strength, the tension of the tension spring 5 and the reaction force of the rotating rod 7 are balanced, ensuring that the sliding plate 2 maintains a stable sliding track 12 when under force. The fixed rod 6 is fixedly connected to the outside of the fixed rod 6. The elastic force of the tension spring 5 keeps the bottom of the shovel plate 11 in contact with the sliding track 12, ensuring that the shovel plate 11 is in close contact with the track surface when cleaning the track, effectively removing debris.

[0034] Each tension spring 5 has a fixed post 4 fixedly connected to its top. The fixed post 4, through its own rigid support, ensures the stability of the pivot point when the rotating rod 7 rotates around the fixed block 3 under the action of the tension spring 5, indirectly controlling the swing amplitude of the shovel 11. Each fixed post 4 has a fixed rotating rod 7 fixedly connected to its rear side. The rotating rod 7 drives the shovel 11 to swing through the fixed rod 8, realizing the contact or separation of the shovel 11 with the sliding rail 12, controlling the start and stop of the cleaning action. Each fixed rod 8 is rotatably connected to its front side. The fixed rod 8, through rigid connection, ensures that the shovel 11 maintains a stable angle when swinging, so that the bottom of the shovel 11 is in uniform contact with the surface of the sliding rail 12, improving the cleaning effect. Each fixed rod 8 has a fixed shovel 11 fixedly connected to its rear side. The bottom edge or flat surface of the shovel 11 is in contact with the surface of the sliding rail 12, removing dust, snow, debris, etc. from the track when the device moves, ensuring the track surface is clean and avoiding debris from affecting the installation accuracy of the photovoltaic module. The outside of the shovel 11 is in contact with the sliding plate 2. The two sides of the shovel plate 11 are in contact with each other. The bottom of the shovel plate 11 is slidably connected to the sliding rail 12. The sliding rail 12 provides precise linear motion guidance, bears the entire weight of the device and the friction during cleaning. The flatness of its surface directly affects the smoothness of the device's movement and the cleaning effect of the shovel plate 11. The bottom of the sliding plate 2 is slidably connected to the top of the sliding rail 12. The inside of the sliding frame 1 is slidably connected to the outside of the sliding rail 12. The front side of the shovel plate 11 is fixedly connected to the support shaft 9. The support shaft 9 provides axial support, allowing the rotating wheel 10 to roll freely when in contact with the rail, reducing the frictional resistance when the device moves. At the same time, it transfers part of the weight of the shovel plate 11 to the sliding frame 1 through the rotating wheel 10. The inside of the support shaft 9 is rotatably connected to the rotating wheel 10. The rotating wheel 10 converts sliding friction into rolling friction, reducing the movement resistance of the device. At the same time, it assists in supporting the front weight of the shovel plate 11 through contact with the fixed block 3. The bottom of the sliding frame 1 is fixedly connected to a component for quick disassembly.

[0035] Reference Figure 4 , Figure 5 The disassembly assembly includes a second fixing column 14, the top of which is fixedly connected to the bottom of the sliding frame 1. A fixing plate 16 is fixedly connected to the outside of the second fixing column 14. The second fixing column 14 serves as the core support for the mounting structure of the detector 13, ensuring the position of components such as the fixing plate 16 and clamping blocks 17 is fixed, thus ensuring the stability of the detector 13 during testing. Two clamping blocks 17 are slidably connected to the outside of the fixing plate 16. By adjusting the spacing of the clamping blocks 17, the fixing plate 16 can accommodate rotating rings 18 of different specifications, achieving universal installation of the detector 13 and enhancing the disassembly and compatibility of the device. The bottom of the clamping blocks 17 is threadedly connected to the rotating ring 18. When the clamping blocks 17 clamp the rotating ring 18, the weight of the detector 13 is transferred to the second fixing column 14. At the same time, the rotation angle of the rotating ring 18 is fixed by the threaded connection, ensuring that the detector 13 is fixed in position during operation.

[0036] The bottom of the rotating ring 18 is fixedly connected to the detector 13. The rotating ring 18 serves as the installation interface for the detector 13, allowing the detector 13 to rotate around the fixed column 14, thereby adjusting the detection direction to meet the detection requirements of different angles and improve detection flexibility. The detector 13 collects data in real time and feeds it back to the control system, providing a basis for equipment maintenance and realizing the detection function of the inspection device. The top of the rotating ring 18 is in contact with the bottom of the sliding frame 1. The rotating ring 18 has a slot 15 inside. When the clamping block 17 is inserted into the slot 15, it restricts the axial movement of the rotating ring 18, while allowing the rotating ring 18 to rotate around the fixed column 14 to adjust the detection angle of the detector 13. The side of the clamping block 17 is in contact with the outside of the fixed column 14. The sliding frame 1 has a groove inside. Multiple support plates 19 are fixedly connected to the side of the sliding frame 1 to prevent deformation of the sliding frame 1 due to uneven force, ensuring the relative position stability of the sliding frame 1 with the sliding plate 2, disassembly components, and other parts, and ensuring the mechanical performance of the overall device.

[0037] Working principle: The sliding frame 1 slides along the sliding rail 12, driving the internal sliding plate 2 to move synchronously. The sliding plate 2 fixes the pivot point of the rotating rod 7 through the fixing block 3. The tension spring 5 connects the fixing column 4 and the component fixing rod 6. Its elastic tension causes the rotating rod 7 to rotate around the fixing block 3. Through the fixing rod 8, the scraper 11 is driven to stick tightly to the surface of the sliding rail 12. The rotating wheel 10 on the front side of the scraper 11 rolls under the action of the support shaft 9 to reduce friction. The scraper 11 removes debris from the track. The bottom disassembly assembly of the sliding frame 1 realizes the cleaning and inspection functions, removes dust, snow, debris, etc. on the track, and avoids them from obstructing the sliding parts of the inspection device, reducing jamming, wear, etc., ensuring that the device moves smoothly along the track, maintaining a stable inspection path and speed. Debris on the track may cause the device to vibrate or deviate, affecting the stability of the mounted detection instrument 13. After cleaning, it can ensure that the detection equipment is in a stable working state and improve the accuracy of data acquisition.

[0038] During component disassembly, the second fixed column 14 is fixed to the bottom of the sliding frame 1, providing support for the fixed plate 16. The two clamping blocks 17 on the fixed plate 16 can slide and adjust their spacing to accommodate different rotating rings 18. The bottom of the clamping block 17 is connected to the rotating ring 18 by threads and is engaged in the internal slot 15 of the rotating ring 18, restricting its axial movement while allowing it to rotate around the second fixed column 14 to adjust the detection angle of the detector 13. The detector 13, fixed to the bottom of the rotating ring 18, moves with the device, collects track data in real time and provides feedback. The support plate 19 enhances the structural strength of the sliding frame 1, ensuring stable installation of the disassembly component and enabling flexible installation, angle adjustment, and reliable detection of the detector 13. After disassembly, the component volume is reduced, making it easier to disassemble and package the device during transportation, reducing transportation costs. It can also be stored separately, saving space and reducing stress loss on the overall structure during long-term storage. This allows faulty components to be quickly separated without disassembling the entire device, shortening maintenance time and reducing maintenance difficulty.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
