Description

Technical Field

[0001] This utility model relates to the field of high-altitude operation and maintenance technology of photovoltaic power plants, and in particular to a support structure for high-altitude operation and maintenance of photovoltaic power plants. Background Technology

[0002] In the daily operation of photovoltaic power plants, high-altitude maintenance is a crucial link in ensuring the efficient and stable operation of the photovoltaic system. Since photovoltaic modules are typically installed on high supports or on rooftops, maintenance personnel need to clean the surface of the photovoltaic panels, check the connection status of the modules, and replace damaged parts—all of which must be performed at height. To meet the needs of working at height, the industry commonly uses movable lifting platforms as maintenance vehicles. These platforms achieve position adjustment through a bottom-mounted moving mechanism (such as self-locking casters) and are driven by a lifting drive device to raise and lower the work platform, thereby transporting maintenance personnel to the designated working position.

[0003] Currently, most support structures rely on self-locking casters or simple support rods at the bottom to fix the working position. However, photovoltaic power stations are mostly located in open areas. In strong winds, the airflow will exert a continuous lateral impact on the support structure. Especially when the wind is strong, the strong wind may directly cause the entire support structure to sway or even swing periodically. This will not only interfere with the operating accuracy of maintenance personnel and increase the difficulty of the operation, but may also cause maintenance personnel to lose balance and fall, resulting in poor safety and stability. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a support structure for the operation and maintenance of photovoltaic power plants at high altitudes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a support mechanism for high-altitude operation and maintenance of a photovoltaic power station, comprising a photovoltaic panel and a movable lifting seat, wherein a vertical plate is fixedly installed on the upper end of the side of the movable lifting seat near the photovoltaic panel, and a limiting support component is slidably provided on the upper end of the vertical plate;

[0006] The limiting support assembly includes a follower plate, a cam is rotatably mounted in the middle of the follower plate, two symmetrical protrusions are provided on the side of the cam, slide rails are provided at both ends of the follower plate, sliders are slidably mounted inside the slide rails, a stop plate is fixedly mounted on the upper side of the slider, and a U-shaped groove is provided on the other end of the stop plate. A mounting bracket is fixedly mounted at the bottom of the photovoltaic panel, the size of the support legs of the mounting bracket is adapted to the inside of the U-shaped groove, and a return spring is fixedly mounted on the side of the two sliders near the cam, and the other end of the return spring is fixedly connected to the inner wall of the slide rail.

[0007] Preferably, a sliding groove is provided in the middle of the upright plate, a movable block is slidably installed inside the sliding groove, a transmission seat is fixedly installed on the side of the movable block near the cam, and a hollow groove is provided inside the transmission seat.

[0008] Preferably, a worm gear is rotatably mounted at the upper center of the hollow groove, the follower plate is fixedly mounted at the end of the transmission seat away from the movable block, and the rotating shaft in the middle of the worm gear passes through the follower plate and is fixedly connected to the rotation axis of the cam.

[0009] Preferably, worm gears are rotatably mounted at both ends of the bottom of the hollow groove, the upper end of the worm gear meshes with the bottom of the worm wheel for transmission, and a drive motor is mounted on the outer side of the bottom of the transmission seat. The output end of the drive motor is connected to one side of the worm gear through a coupling.

[0010] Preferably, the movable block has a screw hole in the middle, and the bottom of the slide groove has an adjustment component. The adjustment component includes a groove, which is opened inside the movable lifting seat and located at the bottom of the slide groove.

[0011] Preferably, a transmission screw is rotatably mounted at both ends of the slide groove, the movable block is threadedly connected to the surface of the transmission screw through a screw hole, and the bottom of the transmission screw is inserted through the groove and fixedly mounted with a bevel gear.

[0012] Preferably, a second bevel gear is meshed with one side of the bottom of the first bevel gear, a drive rod is fixedly installed on the side of the second bevel gear, and the other end of the drive rod passes through the groove and extends to the outside of the movable lifting seat and is fixedly connected to a crank handle.

[0013] Preferably, the movable lifting seat has a support on the side away from the upright plate and a servo motor is installed on its upper end. The output end of the servo motor passes through the top of the support via a coupling and is connected to a screw. The movable lifting seat has a lifting platform on its upper end. One side of the lifting platform is slidably disposed in the support via its own protrusion structure and is threadedly connected to the screw.

[0014] In summary, this utility model has the following beneficial effects:

[0015] 1. By setting up a limit support component, the drive motor drives the worm gear to rotate. The worm gear meshes with the worm wheel, causing the worm wheel to drive the cam to rotate. The convex part of the cam pushes the sliders on both sides to slide along the slide rail, causing the U-shaped groove of the clamping plate to clamp the support leg of the photovoltaic panel mounting frame, connecting the support mechanism to the fixed structure of the photovoltaic panel. This transforms the traditional method of relying on the base for support into a rigid connection with the photovoltaic panel mounting frame, greatly improving the anti-swaying ability of the support mechanism in strong wind environments, avoiding overall swaying caused by lateral wind force, and enhancing the safety of working at heights.

[0016] 2. By setting up the adjustment component, turning the handle drives the drive rod and bevel gear two to rotate. Bevel gear two meshes with bevel gear one to rotate the transmission screw. The movable block slides up and down along the transmission screw through the screw hole, thereby driving the transmission seat and the limit support component to rise and fall synchronously. The clamping position of the limit support component can be flexibly adjusted according to the height of the photovoltaic panel mounting frame, ensuring that the U-shaped groove can accurately engage the support legs of different heights. This enhances stability and improves adaptability to high-altitude operation and maintenance scenarios of photovoltaic power stations of different specifications.

[0017] 3. By setting up a worm gear transmission structure and utilizing its reverse self-locking characteristic, the cam can maintain a stable thrust on the slider after the drive motor stops running, ensuring that the U-shaped groove continuously and tightly engages the support leg. Compared with a transmission structure without self-locking function, this avoids the loosening of the clamping caused by motor power failure or external impact, further ensuring the reliability of the rigid connection, reducing safety hazards in high-altitude operations, and extending the stable operation cycle of the device.

[0030] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings:

[0032] Example: Reference Figures 1-5 A support mechanism for high-altitude operation and maintenance of a photovoltaic power station includes a photovoltaic panel 1 and a movable lifting seat 2. A vertical plate 3 is fixedly installed on the upper end of the side of the movable lifting seat 2 near the photovoltaic panel 1, and a limiting support component 6 is slidably provided on the upper end of the vertical plate 3.

[0033] The limiting support assembly 6 includes a follower plate 602, a cam 601 is rotatably mounted in the middle of the follower plate 602, two symmetrical protrusions are provided on the side of the cam 601, slide rails 603 are provided at both ends of the follower plate 602, sliders 604 are slidably mounted inside the slide rails 603, a retaining plate 606 is fixedly mounted on the upper side of the slider 604, and a U-shaped groove 607 is provided on the other end of the retaining plate 606. A mounting bracket 101 is fixedly mounted at the bottom of the photovoltaic panel 1, and the size of the support leg of the mounting bracket 101 is adapted to the inside of the U-shaped groove 607. A return spring 605 is fixedly mounted on the side of the two sliders 604 near the cam 601, and the other end of the return spring 605 is fixedly connected to the inner wall of the slide rail 603.

[0034] Specifically: In use, the drive motor 54 drives the worm 53 to rotate. The meshing transmission between the worm 53 and the worm wheel 52 causes the worm wheel 52 to drive the cam 601 to rotate continuously in the same direction. As the cam 601 rotates, the protruding part on the side gradually contacts the sliders 604 on both sides and applies a pushing force, causing the sliders 604 to slide along the slide rail 603 away from the cam 601. This, in turn, drives the clamping plate 606 to move synchronously, so as to realize the U-shaped groove 607 clamping the support leg of the photovoltaic panel 1 mounting bracket 101. This can form a stable connection between the support mechanism and the photovoltaic panel 1 mounting bracket 101, changing the The traditional method of relying solely on the bottom structure of the movable lifting seat 2 for fixation effectively improves the anti-sway capability of the support mechanism when working at heights, avoids overall swaying caused by factors such as strong winds, and ensures the safety of maintenance personnel. The cam 601 of the limit support component 6 only needs to rotate in one direction to complete the pushing action of the sliders 604 on both sides. When the protruding part of the cam 601 rotates away from the slider 604, the slider 604 automatically resets under the elastic force of the return spring 605. During this process, the cam 601 always maintains unidirectional rotation and does not need to be reversed, reducing component wear.

[0035] A groove 31 is provided in the middle of the upright plate 3. A movable block 32 is slidably installed inside the groove 31. A transmission seat 5 is fixedly installed on the side of the movable block 32 near the cam 601. The groove 31 in the middle of the upright plate 3 provides a stable sliding guide for the movable block 32. A hollow groove 51 is provided inside the transmission seat 5. A worm gear 52 is rotatably installed in the middle of the upper end of the hollow groove 51. A follower plate 602 is fixedly installed at the end of the transmission seat 5 away from the movable block 32. The rotating shaft in the middle of the worm gear 52 passes through the follower plate 602 and is fixedly connected to the rotation axis of the cam 601, so that the rotation of the worm gear 52 can directly drive the cam 601 to rotate synchronously, realizing the stable transmission of power from the transmission seat 5 to the limiting support component 6.

[0036] Worms 53 are rotatably mounted at both ends of the bottom of the hollow groove 51. The upper end of the worm 53 meshes with the bottom of the worm wheel 52 for transmission. A drive motor 54 is mounted on the outer side of the bottom of the transmission seat 5. The output end of the drive motor 54 is connected to one side of the worm 53 via a coupling. The upper end of the worm 53 meshes with the bottom of the worm wheel 52 for transmission, which can stably transmit the power of the drive motor 54 to the worm wheel 52, thereby driving the cam 601 to rotate and realize the clamping action of the limit support component 6. The worm wheel 52 and worm 53 transmission has a reverse self-locking characteristic. When the drive motor 54 stops running, the worm wheel 52... 2. The worm gear 53 cannot be reversed to rotate, so that the cam 601 can maintain its current position, ensuring that the U-shaped groove 607 of the clamping plate 606 continuously and stably clamps the support leg of the mounting bracket 101, avoiding loosening of the clamp due to external force or unexpected motor stoppage, enhancing the reliability of the connection between the support mechanism and the photovoltaic panel 1 mounting bracket 101, and ensuring the safety of high-altitude operations. The movable block 32 has a screw hole 33 in the middle, and the bottom of the slide 31 has an adjustment component 4. The adjustment component 4 includes a groove 401, which is opened inside the movable lifting seat 2 and located at the bottom of the slide 31.

[0037] The upper and lower ends of the slide 31 are rotatably mounted with transmission screws 402. The movable block 32 is threadedly connected to the surface of the transmission screw 402 through the screw hole 33. When the transmission screw 402 rotates, the movable block 32 can stably rise and fall along the slide 31, thereby driving the transmission seat 5 and the limit support assembly 6 to adjust their height synchronously. This allows for precise adaptation to photovoltaic panel 1 mounting brackets 101 of different heights, ensuring that the U-shaped groove 607 of the limit support assembly 6 is in the corresponding position with the support leg of the mounting bracket 101. This improves the device's adaptability to different operation and maintenance scenarios. The bottom of the lead screw 402 is inserted into the groove 401 and a bevel gear 403 is fixedly installed thereon. A bevel gear 404 is meshed with one side of the bottom of the bevel gear 403. A drive rod 405 is fixedly installed on the side of the bevel gear 404. The other end of the drive rod 405 is inserted into the groove 401 and extends to the outside of the movable lifting seat 2 and is fixedly connected to a crank handle. The bevel gear 403 at the bottom of the lead screw 402 meshes with the bevel gear 403 at the bottom of the lead screw 402, and transmits the rotational force of the crank handle to the lead screw 402, thereby realizing the rotation of the lead screw 402.

[0038] The movable lifting seat 2 has a stand on the side away from the upright plate 3, and a servo motor 201 is installed on its upper end. The output end of the servo motor 201 passes through the top of the stand through a coupling and is connected to a screw 202. The upper end of the movable lifting seat 2 has a lifting platform 203. One side of the lifting platform 203 is slidably set in the stand through its own protrusion structure and is threadedly connected to the screw 202. The servo motor 201 drives the screw 202 to rotate. The protrusion structure of the lifting platform 203 is set in the stand and is threadedly connected to the screw 202. The rotational motion of the servo motor 201 can be converted into the vertical lifting motion of the lifting platform 203, so as to realize the precise adjustment of the working height of the maintenance personnel. This structure is a mature existing technology, so it will not be described in detail.

[0039] The working principle of this utility model is as follows: In specific use, the movable lifting seat 2 is first moved to the working position below the photovoltaic panel 1 by the self-locking universal wheels. Then, the crank of the adjusting component 4 is turned, which drives the bevel gear 404 to rotate through the drive rod 405. The bevel gear 404 meshes with the bevel gear 403 to drive the transmission screw 402 to rotate. The movable block 32 slides up and down along the slide groove 31 of the vertical plate 3 by means of the threaded engagement between the screw hole 33 and the transmission screw 402, thereby driving the transmission seat 5 and the limiting support component 6 to rise and fall synchronously until the support point is adjusted to a suitable position according to the height of the photovoltaic panel 1.

[0040] Next, the drive motor 54 at the bottom of the transmission base 5 is started. The output end of the motor drives the worm 53 to rotate. The worm 53 meshes with the worm wheel 52, causing the worm wheel 52 to drive the cam 601 to rotate. The protruding part of the cam 601 pushes the sliders 604 at both ends of the follower plate 602 to slide along the slide rail 603. The sliders 604 drive the abutment plate 606 to move synchronously, so that the U-shaped groove 607 at the end of the abutment plate 606 is locked onto the support leg of the mounting bracket 101, realizing a rigid connection between the support mechanism and the photovoltaic panel 1 mounting bracket 101, effectively improving the stability during operation.

[0041] Finally, after the operator enters the lifting platform 203, he controls the servo motor 201 to drive the screw 202 to rotate, so that the lifting platform 203 slides along the stand to the appropriate working height. During the operation, the reverse self-locking characteristic of the worm gear 52 and worm 53 transmission can prevent the cam 601 from reversing due to external force or unexpected motor stoppage, ensuring that the U-shaped groove 607 always maintains stable clamping on the support leg. After the operation is completed, the reverse start drive motor 54 resets the cam 601, and the reset spring 605 pulls the slider 604 to drive the clamping plate 606 back, separating the U-shaped groove 607 from the support leg. Finally, the entire device is moved to the next photovoltaic panel installation location for maintenance.
