[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As Figure 1 , 2 shown, a lightning protection and automatic detection device for photovoltaic modules includes a lightning rod 1 and a rain sensor 2. The lightning rod 1 and the rain sensor 2 are arranged on a telescopic assembly 3. Multiple groups of protective frames 4 are arranged on the telescopic assembly 3. The protective frames 4 are unfolded as the telescopic assembly 3 rises. The telescopic assembly 3 is arranged on a support bottom rod 5. A camera detection mechanism 6 is rotatably connected to the support bottom rod 5. The camera detection mechanism 6 includes a camera 61 and an extension rod 62.

[0025] The telescopic component 3 is used to adjust the height of the lightning rod 1. It rises during rainy days to better and faster absorb lightning and prevent the photovoltaic module from being damaged by lightning strikes. The telescopic component 3 includes a fixed rod 31, a telescopic rod 32, a first motor 33, a threaded rod 34, and a slider 35. The fixed rod 31 is provided with a receiving cavity 311. The telescopic rod 32 is slidably connected to the receiving cavity 311. The fixed end of the first motor 33 is provided at the bottom of the receiving cavity 311. The threaded rod 34 is fixedly connected to the output end of the first motor 33. The slider 35 is screwed onto the threaded rod 34. A vertical through hole is provided in the middle of the telescopic rod 32. The diameter of the vertical through hole is larger than the outer diameter of the threaded rod 34. The threaded rod 34 extends into the vertical through hole. The top of the threaded rod 34 is flush with the top of the fixed rod 31. When the first motor 33 rotates, it drives the threaded rod 34 to rotate together.

[0026] A slideway 312 is provided on the side wall of the receiving cavity 311. The slideway 312 is vertically arranged. A protrusion is provided on the side wall of the slider 35. The protrusion is slidably connected to the slideway 312. The slideway 312 restricts the rotation of the slider 35. When the threaded rod 34 rotates, the slider 35 moves up and down along the direction of the slideway 312. When the slider 35 moves upward, it pushes the telescopic rod 32 to rise. When the slider 35 moves downward, it drives the telescopic rod 32 to be received into the receiving cavity 311.

[0027] The top of the telescopic rod 32 is provided with an equipment platform. The lightning rod 1 and the rain sensor 2 are installed on the equipment platform. The rain sensor 2 is signal-connected to the first motor 33. When the rain sensor 2 senses rain, the first motor 33 is started to make the slider 35 rise to increase the height of the lightning rod 1 for lightning protection. Ground wires are arranged inside the telescopic rod 32, the fixed rod 31, and the support bottom rod 5. The ground wires are finally connected to the ground for conduction. After the rain stops, the telescopic rod 32 enters the receiving cavity 311. The receiving cavity 311 protects the telescopic rod 32 from being damaged and increases the service life of the telescopic rod 32.

[0028] There are three groups of protective frames 4, which are distributed in a circular array in the telescopic rod 32 and the fixed rod 31. As Figure 3 shown, the protective frame 4 includes a first frame rod 41, a second frame rod 42, a first hinge 43, and a second hinge 44. The first hinge 43 and the second hinge 44 are located on the same vertical line. The first hinge 43 is provided on the side wall of the fixed rod 31. The second hinge 44 is provided on the telescopic rod 32. The bottom of the first frame rod 41 is rotatably connected to the first hinge 43. The bottom of the second frame rod 42 is rotatably connected to the second hinge 44. The top of the second frame rod 42 is rotatably connected to the side wall of the first frame rod 41. When the telescopic rod 32 is at the lowest point, the first frame rod 41 is received upward. When the telescopic rod 32 rises, the second frame rod 42 pushes the first frame rod 41 to tilt outward and expand.

[0029] The side wall of the first support rod 41 is provided with a rainproof cloth (not shown). After the first support rod 41 is unfolded, the rainproof cloth is stretched. After unfolding, the rainproof cloth covers the photovoltaic modules under this device, reducing the degree of the photovoltaic modules being exposed to rain. In case of hail weather, the rainproof cloth can block some hailstones to reduce the damage to the photovoltaic modules.

[0030] As Figure 4 shown, the camera detection mechanism 6 further includes an annular slide rail 63, a gear disk 64, a second motor 65, a gear shaft 66 and a universal ball seat 67. The annular slide rail 63 is formed by the inner concavity of the side wall of the support bottom rod 5. The gear disk 64 is arranged at the bottom of the annular slide rail 63. The output end of the second motor 65 is fixedly connected with the gear shaft 66, and the gear shaft 66 meshes with the gear disk 64. The top of the second motor 65 is fixedly connected to the rear end of the extension rod 62. The rear end of the extension rod 62 is provided with an annular slider 621, and the annular slider 621 is slidably connected to the annular slide rail 63. The universal ball seat 67 is fixedly connected to the front end of the extension rod 62, and the camera 61 is arranged at the bottom of the universal ball seat 67. During the daily automatic detection of the photovoltaic modules, the gear shaft 66 rotates on the gear disk 64 to drive the extension rod 62 to rotate by the second motor 65. The length of the extension rod 62 covers the photovoltaic modules to be detected. The cooperation between the camera 61 and the rotatable extension rod 62 enables a single camera 61 to monitor more photovoltaic modules, saving the number of cameras 61 and reducing the construction cost. When a problem is found with the photovoltaic modules, the rotation of the camera 61 can be stopped to carefully conduct remote diagnosis on the problem.

[0031] The camera 61 is rotatably connected to the universal ball seat 67. Under the rotation of the universal ball seat 67, the irradiation direction of the camera 61 is always vertically downward. Thus, the problem that the installation of this device on an inclined steep slope may cause deviation in the shooting angle of the camera 61 due to inclination is overcome. The camera 61 that is always vertically downward can detect the photovoltaic modules more clearly and accurately.

[0032] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
