[0022] Please see Figures 1-5As shown, a cloud interference early warning device for photovoltaic power generation includes a support column 8 and an all-sky imager 7. The all-sky imager 7 is a TSI-880 model. A first slide rail 9 is fixed to one side of the support column 8 by bolts. A carrier plate 11 is slidably connected to one side of the first slide rail 9 via a slide table, and the carrier plate 11 is fixed to the all-sky imager 7. A protective component 1 for protecting the all-sky imager 7 from severe weather is provided on the top of the carrier plate 11. A locking component for auxiliary fixing of the carrier plate 11 is provided on one side of the support column 8. 5. A lifting assembly 4 for raising and lowering the carrier plate 11 is provided at the top of the support column 8. The lifting assembly 4 includes a fixing frame 404 fixed to the top of the support column 8 by bolts. Two symmetrically arranged rotating rollers 405 are rotatably connected between the inner walls of the two sides of the fixing frame 404 by bearings. A mounting frame 402 is fixed to one side of the support column 8 and inside the housing 10 by bolts. A winding roller 403 is rotatably connected to the inner wall of one side of the mounting frame 402 by bearings. A drive winding roller 403 is fixed to the outer wall of one side of the mounting frame 402 by bolts. The self-locking motor rotates along the axis. The top of the carrier plate 11 is fixedly connected to the first pull rope 401 by a ring buckle. The other end of the first pull rope 401 passes around two take-up rollers 403 and passes through the housing 10 and is fixed to the take-up rollers 403. The housing 10 is fixed to the outside of the support column 8 and at the bottom position by bolts. The support component 3 is provided on the outside of the support column 8 to increase the stability of the support column 8. The all-sky imager 7 can detect cloud clusters in real time, transmit data to the control system for analysis and early warning. Pulling the locking component 5 makes the carrier plate 11 disengage from the fixed position, and then the self-locking motor is started. The output shaft of the self-locking motor drives the take-up roller 403 to rotate along the axis. The take-up roller 403 unwinds the first pull rope 401. The carrier plate 11 moves downward along the first slide rail 9 due to gravity. The carrier plate 11 drives the all-sky imager 7 to move downward until the all-sky imager 7 reaches the bottom of the support column 8. Finally, the self-locking motor is turned off, which greatly facilitates the maintenance of the all-sky imager 7 and eliminates the need for staff to climb to high places for maintenance.

[0023] To address the technical challenges of protection, this invention employs a protective component 1 comprising two symmetrically arranged sliding grooves 102 formed on the top of a carrier plate 11. Two symmetrically arranged protective shells 101 are slidably connected within the two sliding grooves 102. A driving component 2, which drives the two protective shells 101 to move towards each other, is located at the bottom of the carrier plate 11. The driving component 2 includes two symmetrically arranged second slide rails 203 bolted to the bottom of the carrier plate 11. Two symmetrically arranged sliding plates 201 are slidably connected to the bottom of the two second slide rails 203 via a sliding table. Two symmetrically arranged fixing plates 204 are bolted to the bottom of the carrier plate 11. A bidirectional lead screw is rotatably connected between the two fixing plates 204 via a bearing. 202, one side of the fixed plate 204 is fixed with a servo motor that drives the bidirectional lead screw 202 to rotate along the axis. One side of the protective shell 101 is fixed with a connecting frame 205 by bolts, and the connecting frame 205 passes through the fixed plate 204 and is fixed to the slide plate 201. When encountering severe weather, the servo motor is started, and its output shaft will drive the bidirectional lead screw 202 to rotate. The rotation of the bidirectional lead screw 202 is converted into the two slide plates 201 sliding inward relative to each other on the second slide rail 203 until the two protective shells 101 are tightly fitted together, and a sealed space is formed between the two protective shells 101, which effectively blocks the damage of severe weather such as wind, rain and hail to the all-sky imager 7.

[0024] To solve the technical problem of fixing the carrier plate 11, the present invention employs a locking assembly 5 including two third slide rails 507 fixed to one side of the support column 8 by bolts. A locking block 502 is slidably connected to one side of each third slide rail 507 via a slide table. A locking groove 501 is provided on the side of the carrier plate 11 near the support column 8 to engage with the locking block 502. An inclined surface is provided on the lower side of the locking block 502. A support plate 508 is fixed to one side of the support column 8 by bolts. A spring 503 is provided between the support plate 508 and the locking block 502. One end of the spring 503 is fixed to the support plate 508, and the other end is fixed to the locking block 502. A pulling assembly is provided on one side of the support plate 508 to disengage the locking groove 501 from the locking block 502. The assembly includes a guide frame 505 bolted to one side of the support plate 508, and a second pull rope 506 fixed to one side of the locking block 502 by a ring buckle. The other end of the second pull rope 506 passes through the support plate 508 and wraps around the guide frame 505 to be fixed to the housing 10. When the all-sky imager 7 needs to be disassembled, the second pull rope 506 is pulled, which moves the locking block 502, causing the locking block 502 to disengage from the slot 501. Through the second pull rope 506, it is not necessary to climb to a high place to disengage the carrier plate 11. Under the action of the spring 503, the locking block 502 is inserted into the slot 501, thereby fixing the carrier plate 11 and making the carrier plate 11 more stable.

[0025] To address the technical problem of supporting the support column 8, this invention employs a support assembly 3 comprising multiple evenly distributed support frames 301 fixed to the outside of the support column 8 by bolts. A second support rod 303, with one end fixed to the support column 8 and inclined, is welded to the top inner wall of each support frame 301. A first support rod 302, with one end fixed to the second support rod 303 and inclined, is welded to the inner wall of one side of each support frame 301. The even distribution of multiple support frames 301 on the outside of the support column 8 increases the stability of the support column 8. The inclined arrangement of the first and second support rods 302 and 303, working together to form a triangular structure, further enhances the stability of the device. Furthermore, the fixed connection of both the first and second support rods 302 to the support column 8 results in a superior support effect.

[0026] It should be noted that servo motors and self-locking motors are existing technologies, and those skilled in the art can set them according to actual needs, which will not be elaborated here.

[0027] In this application, the inner walls of the threaded holes of the two slide plates 201 that mate with the bidirectional lead screw 202 are provided with annular grooves. Nylon 66 damping rings with a Shore hardness of 85A are embedded in the grooves. Through the continuous axial clamping force generated by its elastic deformation, a helical angle interference fit of 15°-20° is formed with the surface of the threaded rod. When the threaded pair is subjected to axial vibration load, the nylon insert can generate a maximum elastic compression of 0.3mm, which increases the friction coefficient between the thread contact surfaces from 0.15 to 0.68 (tested according to ASTM D1894 standard), effectively suppressing loosening displacement caused by thread springback.

[0028] The present invention is used in the following steps: S1: First pull the second pull rope 506. The second pull rope 506 drives the locking block 502 to move, so that the locking block 502 disengages from the locking slot 501. S2: Then start the self-locking motor. The output shaft of the self-locking motor drives the take-up roller 403 to rotate along the axis. The take-up roller 403 unwinds the first pull rope 401. Due to gravity, the carrier plate 11 moves downward along the first slide rail 9. The carrier plate 11 drives the all-sky imager 7 to move downward until the all-sky imager 7 reaches the bottom of the support column 8. Finally, the self-locking motor is turned off, which facilitates the maintenance of the all-sky imager 7. S3: After maintenance is completed, start the self-locking motor. The output shaft of the self-locking motor reverses and drives the take-up roller 403 to rotate along the axis. The take-up roller 403 winds up the first pull rope 401. The first pull rope 401 pulls the carrier plate 11 upward along the first slide rail 9. The carrier plate 11 drives the all-sky imager 7 to move upward until the all-sky imager 7 reaches the top of the support column 8. Finally, turn off the self-locking motor. S4: When the carrier plate 11 is about to reach the top, the carrier plate 11 will contact the inclined surface of the locking block 502. As the carrier plate 11 continues to move upward, the carrier plate 11 will press against the inclined surface of the locking block 502, causing the locking block 502 to slide along the third slide rail 507. At the same time, the spring 503 will be compressed. When the carrier plate 11 moves to the top, the carrier plate 11 will detach and contact the inclined surface. At the same time, the spring 503 will rebound, causing the locking block 502 to be locked into the slot 501, thereby providing auxiliary fixation for the carrier plate 11.

[0029] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0030] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
