Description

Technical Field

[0001] This utility model relates to the field of new energy photovoltaic power generation technology, specifically a multi-layer photovoltaic panel placement rack. Background Technology

[0002] A solar photovoltaic panel is a sheet material assembled from several solar cells in a certain way to receive solar energy. A solar photovoltaic panel module is a power generation device that generates direct current when exposed to sunlight. It is an important component that converts light energy into electrical energy, consisting of thin solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon).

Each layer of the lifting platform has lifting rods at its four corners, each lifting rod extending along the X-axis and equipped with lifting wheels. The frame has a frame at each end of the X-axis, and a lifting assembly within each frame transmits lifting power along the Z-axis. The end of each lifting rod with a lifting wheel extends into the frame, allowing the lifting wheel to engage with the lifting assembly.

However, this design will lead to a complex device structure, which is prone to failure due to gear wear. In addition, the photovoltaic panel located at the bottom of the lifting platform has poor light reception. Even if the lifting platform can be raised, the upper lifting platform will still block some light, affecting the light reception of the bottom photovoltaic panel. Utility Model Content

[0022] The specific embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0023] Please see Figure 1-5A multi-layer photovoltaic panel placement rack includes columns 1, a lifting platform 2, and a movable platform 3. There are four columns 1. A lifting mechanism 4 is provided on one side of the lifting platform 2. A forward pushing mechanism 5 is provided on one side of the movable platform 3. A stabilizing mechanism 6 is provided on the surface of the columns 1. Self-locking casters 7 are fixed at the bottom of the columns 1. A connecting horizontal plate 8 is fixed between the two rear columns 1. The lifting platform 2 is located above the movable platform 3.

[0024] Through the above technical solution, the column 1, the lifting platform 2, and the movable platform 3 constitute the main frame. The column 1 forms a rectangular support through the connecting horizontal plate 8, and the lifting platform 2 is located above the movable platform 3. The self-locking casters 7 facilitate the overall movement, and the stabilizing mechanism 6 can increase the friction between the device and the ground after arriving at the site to complete the positioning. The overall layered layout can multiply the number of photovoltaic panels, increase the photovoltaic power generation per unit area, and enable flexible movement through the casters during transportation, installation, and maintenance. The stabilizing mechanism 6 ensures working stability, takes into account both movement and fixation requirements, reduces the intensity of manual handling, improves deployment efficiency, and solves the contradiction that traditional fixed supports cannot balance movement and stability.

[0025] The lifting mechanism 4 includes a connecting shaft 401, which is rotatably connected to the surfaces of the two front columns 1. One end of the connecting shaft 401 passes through the column 1 and is fixed with a first pulley 402. A lower connecting plate 403 and an upper connecting plate 405 are fixed between the front and rear columns 1. A second pulley 404 is rotatably connected to the surface of the lower connecting plate 403, and a third pulley 406 is rotatably connected to the surface of the upper connecting plate 405. A steel rope 408 is fixed to the surface of the first pulley 402. Extension rods 407 are fixed to both sides of the surface of the lifting platform 2. The surface of the steel rope 408 is slidably connected to the surfaces of the second pulley 404 and the third pulley 406. One end of the steel rope 408 is fixedly connected to the surface of the extension rod 407. An extension frame 412 is fixed to the surface of one column 1. A drive motor 413 is fixed to the top of the extension frame 412. The output shaft of the drive motor 413 is fixedly connected to one end of the connecting shaft 401. The drive motor 413 is a worm gear reducer motor.

[0026] Through the above technical solution, in the lifting mechanism 4, the drive motor 413 drives the connecting shaft 401 to rotate, the first pulley 402 rotates accordingly and winds up the steel rope 408. The steel rope 408 passes through the second pulley 404 and the third pulley 406 in sequence and then pulls the extension rod 407, causing the lifting platform 2 to rise. The pulley group and the steel rope 408 cooperate to replace the gear and rack, reducing meshing wear and lowering the failure rate. The symmetrical arrangement of the extension rod 407 ensures that the platform is evenly stressed, prevents tilting, and extends its service life. The mechanism has a simple structure and smooth power transmission. During maintenance, only the wear of the steel rope 408 needs to be checked, which greatly reduces maintenance time and cost. It solves the problems of easy wear, high noise, and complex maintenance of traditional gear lifting. At the same time, the worm gear reducer motor has a self-locking function, which can prevent the motor output shaft from rotating after power failure.

[0027] The forward pushing mechanism 5 includes a combination plate 501, which is fixed between the front and rear columns 1. There are two combination plates 501 on the surface of the front and rear columns 1. A support horizontal plate 508 is fixed on the surface of the lower combination plate 501. An electric cylinder 502 is fixed on the surface of the support horizontal plate 508. One end of the electric cylinder 502 passes through the support horizontal plate 508 and is fixed with an extension block 503. The top of the extension block 503 is fixedly connected to the bottom of the movable platform 3.

[0028] Through the above technical solution, in the forward pushing mechanism 5, the telescopic end of the electric cylinder 502 drives the movable platform 3 to move back and forth through the extension block 503. When the movable platform 3 is pushed forward, the photovoltaic panels on its surface can avoid the obstruction of the lifting platform 2 and obtain more direct sunlight, thus improving the power generation efficiency. When it is retracted, the platform overlaps with the lifting platform 2, reducing the footprint. The electric cylinder 502 achieves precise stroke control, avoiding manual pushing and pulling and reducing labor intensity. The mechanism is fast and accurate in positioning, significantly improving the light reception effect of the bottom photovoltaic panels and solving the problem of insufficient light at the bottom layer when multiple layers are stacked.

[0029] The stabilizing mechanism 6 includes a block 601, which is fixedly connected to the surface of the column 1. A shank screw 602 is threaded through the surface of the block 601, and a rubber friction pad 603 is fixed to the bottom of the shank screw 602.

[0030] Through the above technical solution, the block 601 in the stabilizing mechanism 6 is fixed on the column 1. After the screw 602 with a handle is screwed into the block 601, the rubber friction pad 603 at the bottom contacts the ground and generates friction, preventing the casters from rolling. The handle design facilitates quick manual rotation, and the rubber friction pad 603 can adapt to uneven ground, increasing the contact area and preventing the equipment from shifting under wind or external force. This mechanism can lock and unlock without additional tools, making it simple to operate, improving on-site deployment efficiency, reducing shaking caused by uneven foundation, ensuring the safety of photovoltaic panels, and solving the hidden dangers of unstable and slippery mobile equipment.

[0031] The first linear slide rail 410 is fixed on the surface of the column 1. Two L-shaped plates 409 are fixed on the left and right sides of the surface of the lifting platform 2. The first slider 411 is slidably connected to the surface of the first linear slide rail 410. The surface of the first slider 411 is fixedly connected to the surface of the L-shaped plate 409.

[0032] Through the above technical solution, the first linear slide rail 410 and the first slider 411 form a sliding pair. The first slider 411 is fixedly connected to the lifting platform 2 through the L-shaped plate 409, so that the platform moves along a predetermined trajectory when lifting and lowering, preventing swaying. The slide rail and slider bear vertical and lateral loads, disperse the tension of the steel rope 408, reduce stress concentration at single points, and extend the service life of the structure. This structure enables the lifting platform 2 to remain stable under heavy load, reduces the risk of photovoltaic panels being damaged by vibration, improves system reliability, and solves the problems of platform swaying and easy collision of photovoltaic panels during lifting and lowering.

[0033] An extension leg 506 is fixed to the bottom of the activity platform 3. A support caster 507 is fixed to the bottom of the extension leg 506. The extension leg 506 is located in front of the support plate 508.

[0034] Through the above technical solution, the extension leg 506 is fixed to the bottom of the movable platform 3, and the support caster 507 contacts the ground when the platform is pushed forward, forming a four-point support to share the load of the column 1 and the caster, and avoid cantilever deformation; the caster has low rolling resistance and rolls with the platform without adding extra thrust; this design enhances the rigidity of the platform, prevents sagging or shaking when the platform is pushed forward for a long stroke, protects the photovoltaic panel, and maintains overall mobility.

[0035] Multiple wheel frames 509 are fixed on the opposite surfaces of the upper and lower combination plates 501. Support rollers 510 are rotatably connected to the surface of the wheel frames 509, and the surface of the support rollers 510 is slidably connected to the surface of the movable platform 3.

[0036] Through the above technical solution, the wheel frame 509 and the support roller 510 are installed between the upper and lower combined plates 501. The support roller 510 makes rolling contact with the bottom surface of the movable platform 3, transferring the platform's gravity to the combined plate 501, reducing the lateral force on the electric cylinder 502, and reducing wear and noise.

[0037] A second linear slide rail 504 is fixed between the front and rear columns 1. A second slider 505 is slidably connected to the surface of the second linear slide rail 504. The surface of the second slider 505 is fixedly connected to the surface of the movable platform 3.

[0038] Through the above technical solution, the second linear slide rail 504 and the second slider 505 form a high-precision guide pair, which is fixed between the front and rear columns 1 to provide linear guidance for the movable platform 3; the slider is fixed to the platform, which restricts the lateral and torsional degrees of freedom of the platform and ensures that the push-out and retraction paths are consistent.

[0039] Working principle: The operator pushes the entire frame to the installation position using the self-locking casters 7, and tightens the shank screw 602 in the stabilizing mechanism 6 to press the rubber friction pad 603 firmly against the ground to complete the fixation; then, the photovoltaic panels are placed on the lifting platform 2 and the movable platform 3 respectively, the drive motor 413 is started, and its output shaft drives the connecting shaft 401 and the first pulley 402 to rotate. The first pulley 402 winds up the steel rope 408, and the steel rope 408 passes through the second pulley 404 and the third pulley 406 in sequence before pulling the extension rod 407, so that the lifting platform 2 rises smoothly under the guidance of the first linear slide rail 410 and the first slider 411, and stops after reaching the required height; when it is necessary to enhance the light reception of the bottom photovoltaic panels, the electric cylinder 502 extends, and its piston rod passes through... The extension block 503 pushes the movable platform 3, which slides forward along the support roller 510 under the constraint of the second linear slide rail 504 and the second slider 505. The support casters 507 at the bottom of the extension leg 506 simultaneously touch the ground to form auxiliary support, so that the photovoltaic panels on the movable platform 3 are fully exposed to direct sunlight. When retracting, the electric cylinder 502 retracts, the platform resets, the drive motor 413 reverses, and the lifting platform 2 descends to the initial position, completing one work cycle. The whole process realizes the flexible scheduling of photovoltaic panels in the vertical and horizontal directions through the coordinated action of the motor and the electric cylinder 502. It not only ensures compactness during transportation and installation, but also maximizes the light-receiving area during operation, solving the problems of complex and easily damaged gears in traditional multi-layer frames and insufficient light reception of the bottom photovoltaic panels.
