Detailed Implementation

[0027] 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.

[0028] See Figure 1-7As shown, the photovoltaic power station operation and maintenance inspection device includes a first column 1 and a second column 2. The lower ends of the first column 1 and the second column 2 are fixed to the location of the photovoltaic power station by bolts. The height of the first column 1 and the second column 2 is higher than that of the photovoltaic panels in the photovoltaic power station. When the inspection length is long, the number of columns can be increased to improve the support capacity. A track assembly is set between the first column 1 and the second column 2 to provide guidance for movement between the top of the first column 1 and the top of the second column 2. Preferably, the track assembly provides a horizontal guide trajectory. This inspection device is relatively suitable for the inspection of photovoltaic power stations installed on the roof of buildings. Of course, in the actual construction, the height of the columns can be selected according to different construction sites to make the track assembly more horizontal. When the area of ​​the photovoltaic power station to be inspected is large, multiple inspection devices can be set up, with one inspection device responsible for the inspection of a certain area of ​​the photovoltaic power station.

[0029] The mobile inspection component installed on the track assembly is used to move on the track assembly between the first column 1 and the second column 2 to change the position of the mobile inspection component and inspect the photovoltaic power station. The top side of the first column 1 and the second column 2 are respectively provided with support blocks 3 extending outward from the column to provide support for the installation position of the track assembly. The track assembly is located between the two support blocks 3 below.

[0030] The mobile inspection component includes a mobile housing, a rolling mechanism, a drive component, an inspection camera 4, and a photovoltaic power generation component. The rolling mechanism is mounted on the upper part of the outside of the mobile housing and moves together with the mobile housing. The rolling component is rolled on the track component, that is, the rolling mechanism enables the mobile housing to move on the guide trajectory of the track component.

[0031] The drive assembly is housed within the mobile enclosure, which provides some protection for it. A transmission assembly connects the drive assembly and the track assembly, providing driving force which is then converted into the ability for the mobile enclosure to move on the track assembly. A photovoltaic power generation module is mounted on the outer side of the upper part of the mobile enclosure to receive sunlight and convert it into electrical energy. An inspection camera 4 is installed below the mobile enclosure to inspect the photovoltaic power station site and obtain images of the site. The photovoltaic power generation module is electrically connected to the drive assembly and the inspection camera 4, using the electricity generated by the photovoltaic module to power these components. The inspection camera 4 is a wireless network camera, enabling communication with external user terminals.

[0032] In one embodiment, the track assembly includes a square support profile 5, two track base plates 6, and two tracks 7. The ends of the support profile 5 are fixed to the bottom of the support block 3 by screws. The two sides of the support profile 5 are mounting surfaces for mounting the track base plates 6. The two track base plates 6 are welded and fixed to the left and right sides of the support profile 5, and the two track base plates 6 are symmetrically arranged with respect to the vertical center line of the support profile 5. The upper surface of the track base plate 6 is a horizontal base surface for mounting the tracks 7. The two tracks 7 are mounted one-to-one on the upper surfaces of the two track base plates 6, and the two tracks 7 are arranged in parallel at the same height, that is, the tracks 7 are at the same height and remain parallel to each other. The track 7 has a toothed cross-section, that is, the track 7 includes a toothed portion 8 and a connecting portion 9 located below the two sides of the toothed portion 8. The connecting portion 9 is connected to the track base plate 6 by screws, and the toothed portion 8 is arranged facing upward.

[0033] In one embodiment, the rolling mechanism includes four rolling components, which are arranged in pairs on both sides of the track assembly. The rolling mechanism is used to support the movable box, which is suspended on the track, and through the cooperation between the rolling mechanism and the track, the movable box has the ability to move. The rolling components include rollers 10, support blocks 11, and mounting columns 12. The lower end of the support block 11 is fixedly connected to the top of the movable box by bolts at the bottom. One end of the mounting column 12 has a rectangular cross-section and is located above the support block 11. The other end of the mounting column 12 has a circular cross-section and is located above the track. The upper side of the support block 11 is fixedly connected to one end of the mounting column 12 by bolts. The roller 10 is rotatably mounted to the other end of the mounting column 12 by bearings. The support block 11 is arranged vertically, and the mounting column 12 is arranged horizontally. The outer peripheral surface of the roller 10 is a rolling surface that cooperates with the track in the track assembly. The rolling surface includes toothed grooves 13 that adapt to the toothed portion 8 and outer peripheral rolling surfaces 14 that roll in cooperation with the upper surface of the connecting portion near the root of the toothed portion 8. The engagement of the toothed portion 8 and the toothed groove 13 can guide the movement of the roller 10 on the track, and at the same time reduce the possibility of the roller 10 deviating left or right on the track.

[0034] In one embodiment, the distance between the inner side of the support block 11 and the outer end face of the track mounting plate is less than half the width of the roller 10. This way, even if the roller 10 deviates during rolling, the outer end face of the track mounting plate will block the inner side of the support block 11, preventing the toothed groove 13 on the roller 10 from disengaging from the toothed portion 8 on the track, thereby further enhancing the rolling stability.

[0035] In one embodiment, the drive assembly includes a motor 15, a reducer 16, and a drive shaft 17 housed in a movable housing. The motor 15 is a reversible servo motor and may be equipped with an electromagnetic brake to enable braking functionality. The output end of the motor 15 is connected to the input end of the reducer 16, and the output end of the reducer 16 is connected to the drive shaft 17. The drive shaft 17 is horizontally mounted in the center of the movable housing via two bearing seats 18. That is, the rotation of the motor 15 can drive the drive shaft 17 through the reducer 16, causing it to rotate around its own axis on the two bearing seats 18.

[0036] The transmission assembly includes a gear 19 and a rack 20. The gear 19 is fixedly mounted on the drive shaft 17 located between two bearing seats 18 and rotates together with the drive shaft 17. The rack 20 is fixedly mounted on the center of the lower surface of the support profile 5 and is arranged along the length of the support profile 5. Specifically, a mounting groove 21 is provided in the center of the lower surface of the support profile 5 along its length. A countersunk screw fixes a mounting block 22 in the mounting groove 21. The mounting block 22 has a concave structure with the recess facing downward. The lower end of the mounting block 22 protrudes from the mounting groove 21. The rack 20 is inserted into the recess of the mounting block 22. Then, a screw is inserted from the outside of the mounting block 22 to install the rack 20 in the mounting block 22. The teeth of the rack 20 protrude from the mounting block 22 and mesh with the gear 19.

[0037] A slot 23 is provided at the center of the top of the movable housing to expose the outer periphery of the gear 19. The gear 19 exposed outside the movable housing meshes with the rack 20, so that the gear 19 can move relative to the rack 20, thereby driving the movable housing to move.

[0038] A barrier 24, higher than the top surface of the mobile housing, is fixedly installed on the top of the mobile housing. The barrier 24 encloses the slot and its height does not exceed the outer periphery of the gear 19, allowing the outer periphery of the gear 19 to protrude from the barrier 24 and mesh with the rack 20. L-shaped baffles 25 are installed on both sides of the lower surface of the supporting profile 5. The lower ends of the L-shaped baffles 25 are below the upper surface of the barrier 24. The barrier 24 and L-shaped baffles 25 reduce the probability of external water flowing from the upper surface of the mobile housing into the mobile housing through the slot. The L-shaped baffles 25 can be made of rubber, with the lower ends directly contacting the upper surface of the mobile housing to enhance the barrier's effectiveness.

[0039] In one embodiment, the photovoltaic power generation module includes a photovoltaic module 26 and a battery pack 27 electrically connected to the photovoltaic module 26. The battery pack 27 is used to receive the electrical energy generated by the photovoltaic module. The photovoltaic module is installed on the upper outer side of the mobile housing, and the battery pack is located inside the mobile housing. The battery pack is electrically connected to the motor 15 and the inspection camera 4 in the drive assembly for power supply. An L-shaped support plate 28 is fixedly installed on the upper outer side of the mobile housing for mounting the photovoltaic module. Inside the mobile housing, the motor 15 and the battery pack are positioned on both sides of the gear 19 to balance the weight of the entire mobile housing as much as possible. A wireless communication module is built into the mobile housing and connected to the controller signal of motor 15. The wireless communication module can send signals to the motor 15 controller to control the working state of motor 15. For example, when inspection is required, motor 15 is activated, and the engagement of gear 19 and rack 20 causes the mobile housing to move, thus moving the inspection camera 4, which can then perform inspection work. When inspection is finished or not required, motor 15 is turned off, stopping the inspection. When inspection is not needed, the mobile housing can move to below the support block 3 on the column, where the support block 3 shields the rollers 10, providing some protection. Numbers are affixed to the column within the camera's field of view below the inspection camera 4 to facilitate identification of the inspection location.

[0040] In one embodiment, the mobile housing includes a housing 29 with an open top, a cover 30 that is screwed to the open end of the housing 29, and a rolling mechanism and a photovoltaic module that are mounted on the cover 29 to facilitate the assembly and disassembly of the mobile housing.

[0041] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
