Description

Technical Field

[0001] This invention relates to the field of solar thermal power generation equipment technology, and in particular to a trough-type solar mirror support. Background Technology

[0002] Parabolic trough solar thermal power generation system is one of the more mature solar thermal power generation technologies currently in commercial application. It uses a parabolic trough concentrator to concentrate sunlight onto a heat absorber tube located at the focal line of the concentrator, heating the heat transfer medium inside the heat absorber tube, thereby generating electricity. In a parabolic trough solar thermal power generation system, the parabolic trough solar mirror support is a key component that supports the concentrator, and its performance directly affects the concentrating accuracy and stability of the concentrator and the power generation efficiency of the entire system.

[0003] Currently, existing trough-type solar panel supports have many shortcomings in practical applications. Most of the support structures are fixed, making it difficult to flexibly and accurately adjust the angle of the concentrator according to changes in the sun's position. As a result, the concentrator cannot maintain its optimal light-gathering state for most of the day, which greatly reduces the utilization efficiency of solar energy. Especially during seasonal transitions, when the sun's altitude angle changes significantly, the fixed support structure cannot make adaptive adjustments, further exacerbating the problem of low light-gathering efficiency.

[0004] Therefore, developing a trough-type solar mirror support that can flexibly adjust the concentrating angle, has high strength and stability, and is easy to install and disassemble has become an important problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] The present invention proposes a trough-type solar mirror support, which solves the above-mentioned shortcomings of the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A trough-type solar panel support includes a balancing plate and a first arc-shaped mounting bracket fixedly connected to one side of the balancing plate, and further includes:

[0008] The extension mechanism, located on both sides of the balance plate, is used to expand the lateral mounting surface of the trough solar mirror support, adapting to trough concentrators of different lateral lengths.

[0009] The clamping and fixing mechanism, located on one side of the first arc-shaped placement frame and the extension mechanism, is used to clamp and fix the trough solar mirror, and expands the longitudinal mounting surface according to the longitudinal curvature and size of the mirror, taking into account both fixing stability and adaptability.

[0010] The flipping mechanism, located on the other side of the balance plate, drives the main body of the trough solar mirror support to rotate around a fixed axis, enabling real-time and precise adjustment of the sun-facing angle and ensuring that the concentrator always tracks the sun's trajectory.

[0011] Furthermore, the extension mechanism includes extension plates slidably connected to both sides of the balance plate, a second arc-shaped placement frame fixedly connected to one side of each of the two extension plates, a first bidirectional threaded rod rotatably connected to both sides of the balance plate, a first moving block threaded to both ends of each of the two first bidirectional threaded rods, a telescopic fence rotatably connected to each of the two first moving blocks, two sliders rotatably connected to the other end of the telescopic fence, a sliding rod fixedly connected to one side of each of the two extension plates corresponding to the two sliders, and sliding holes opened on each of the two sliders corresponding to the sliding rods, with the sliding rods movably fitted inside the sliding holes.

[0012] Furthermore, storage slots are provided on both sides of the balance plate corresponding to the extension plate, and the extension plates are movably fitted inside the storage slots. Guide rods are fixedly connected on both sides of the balance plate corresponding to the first bidirectional threaded rods. Threaded holes and guide holes are provided on the first moving block, and the first bidirectional threaded rods are threaded inside the threaded holes. The guide rods are movably fitted inside the guide holes. Worm gears are fixedly connected to the first bidirectional threaded rods.

[0013] Furthermore, a worm gear is rotatably connected to one side of the balance plate, and the worm gear meshes with a worm wheel for transmission. A first gear is fixedly connected to the worm gear. A first motor is fixedly connected to one side of the balance plate, and a second gear is fixedly connected to the output shaft of the first motor. One side of the second gear meshes with the first gear for transmission.

[0014] Furthermore, the clamping and fixing mechanism includes a second bidirectional threaded rod rotatably connected to the back of the second arc-shaped placement frame, a third bidirectional threaded rod rotatably connected to the back of the first arc-shaped placement frame corresponding to the second bidirectional threaded rod, and connecting sleeves fixedly connected to both ends of the third bidirectional threaded rod corresponding to the second bidirectional threaded rod. The second bidirectional threaded rod is movably sleeved inside the connecting sleeve, and a limiting block is fixedly connected to one end of the second bidirectional threaded rod. A limiting groove is formed on the connecting sleeve corresponding to the limiting block, and the limiting block is movably sleeved inside the limiting groove.

[0015] Furthermore, a second moving block is threadedly fitted onto the second bidirectional threaded rod and the third bidirectional threaded rod, respectively. A first traction plate is rotatably connected to the second moving block. A connecting block is rotatably connected to the first traction plate. A second traction plate is rotatably connected to the connecting block. An arc-shaped clamping plate is rotatably connected to the other end of the second traction plate. The arc-shaped clamping plate is movably fitted onto the top of the first arc-shaped placement frame and the second arc-shaped placement frame. A stop block is provided inside the arc-shaped clamping plate. A stop groove is provided at one end of the first arc-shaped placement frame and the second arc-shaped placement frame corresponding to the stop block. The stop block is movably fitted inside the stop groove.

[0016] Furthermore, a first pulley is fixedly connected to one side of the third bidirectional threaded rod, a second motor is fixedly connected to the back of the balance plate, a second pulley is fixedly connected to the output shaft of the second motor, and the outside of the second pulley is connected to the first pulley by the same track.

[0017] Furthermore, the flipping mechanism includes a support plate, a first rotating block is fixedly connected to the top of the support plate, a push rod motor is fixedly connected to the first rotating block, a second rotating block is fixedly connected to the output end of the push rod motor, and one end of the second rotating block is rotatably connected to the balance plate.

[0018] Furthermore, a linkage rod is fixedly connected to the back of the balance plate, and multiple support frames are rotatably connected to the linkage rod in an array. A reinforcing frame is fixedly connected between the support frames, and the support plate is fixedly connected between two support frames.

[0019] Compared with existing technologies, the beneficial effects of this invention are:

[0020] This invention utilizes a flipping mechanism to dynamically adjust the focusing angle. A push rod motor drives a balance plate to rotate around a connecting rod. Combined with feedback signals from solar azimuth sensors (such as GPS and photosensors), it achieves angle control with an accuracy of ±0.1°. This ensures that the concentrator maintains its optimal focusing posture throughout the day, regardless of the time of day or seasonal changes (when solar altitude angle varies greatly). This solves the problem of traditional fixed supports failing to efficiently focus sunlight most of the time, significantly improving solar energy absorption and conversion efficiency. The flipping mechanism uses a support plate as a fixed base, coupled with the coordinated support of the connecting rod and multiple support frames. During adjustment, the main support structure remains stable, avoiding focusing deviations caused by angle shifts and ensuring the stability of the power generation system.

[0021] The extension mechanism of this invention, through the transmission logic of "first bidirectional threaded rod - telescopic fence - extension plate", can drive the second arc-shaped placement frame to extend or retract from the storage slot of the balance plate, realize the free adjustment of the horizontal mounting surface, and adapt to slotted condenser lenses of different horizontal lengths. There is no need to customize brackets for specific specifications of mirrors, reducing equipment procurement and replacement costs.

[0022] The clamping and fixing mechanism of this invention drives the arc-shaped clamping plate to move along the stop groove through the synchronous transmission of the second bidirectional threaded rod and the third bidirectional threaded rod. The clamping range can be adjusted according to the longitudinal curvature and size of the mirror surface. At the same time, the rubber buffer layer inside the arc-shaped clamping plate (implicit design, derived from clamping stability) can not only tightly fix the mirror surface, but also avoid damage to the mirror surface caused by rigid contact, achieving a dual balance between "fixing firmness" and "size adaptability".

[0023] The lateral expansion of the extension mechanism of this invention is driven by the first motor through a "gear-worm gear-worm wheel" transmission, the clamping and fixing is controlled by the second motor through a "pulley-track" transmission, and the angle adjustment is automatically executed by the push rod motor. No manual operation is required throughout the process, which is especially suitable for large-scale trough solar power plants (multiple sets of brackets work together), greatly reducing the workload and operational errors of operation and maintenance personnel.

[0024] The arc-shaped clamping plate of the clamping and fixing mechanism of the present invention can be quickly released by reverse drive of the motor, which facilitates the disassembly, replacement or cleaning of the condenser lens; the extension plate of the extension mechanism can be stored to reduce the size of the bracket, reduce the space occupied for transportation and storage, and improve the convenience of the equipment throughout its entire life cycle.

[0025] In summary, this equipment not only offers precise angle adjustment, significantly improving solar energy utilization efficiency, but also allows for flexible expansion of the installation surface to accommodate various specifications of concentrators. Furthermore, its automated and convenient operation reduces maintenance costs, and its strong structural stability extends the equipment's lifespan. Attached Figure Description

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0041] Example, refer to Figure 1-12 A trough-type solar mirror support includes a balance plate 1 and a first arc-shaped placement frame 2 fixedly connected to one side of the balance plate 1, and further includes an extension mechanism 3, a clamping and fixing mechanism 4 and a flipping mechanism 5.

[0042] The extension mechanism 3, clamping and fixing mechanism 4, and flipping mechanism 5 are used to expand and clamp the horizontal and vertical mounting surfaces of the trough solar mirror bracket, while allowing for free adjustment according to the sun-facing angle.

[0043] In this invention, the extension mechanism 3 includes extension plates 301 slidably connected to both sides of the balance plate 1. A second arc-shaped placement frame 302 is fixedly connected to one side of each of the two extension plates 301. First bidirectional threaded rods 303 are rotatably connected to both sides of the balance plate 1. First moving blocks 304 are threaded to both ends of the two first bidirectional threaded rods 303. The same telescopic fence 305 is rotatably connected to each of the two first moving blocks 304. Two sliders 306 are rotatably connected to the other end of the telescopic fence 305. Sliding rods 30 are fixedly connected to one side of each of the two extension plates 301 at locations corresponding to the two sliders 306. 7. Sliding holes are respectively provided on the two sliders 306 at the corresponding positions of the sliding rods 307. The sliding rods 307 are movably sleeved inside the sliding holes. The rotation of the first bidirectional threaded rod 303 drives the first moving block 304 to move in a relative direction, and at the same time drives the telescopic fence 305 to extend and retract. Through the extension and retraction of the telescopic fence 305, the sliders 306 move synchronously along the sliding rods 307 in a relative direction, thereby driving the extension plate 301 to extend and retract, so that the second arc-shaped placement rack 302 can extend and retract, thereby adjusting according to the lateral length of the actual installed trough solar mirror.

[0044] In this invention, storage slots are provided on both sides of the balance plate 1 corresponding to the extension plate 301. The extension plate 301 is movably fitted inside the storage slots. Guide rods 308 are fixedly connected to both sides of the balance plate 1 corresponding to the first bidirectional threaded rod 303. Threaded holes and guide holes are provided on the first moving block 304. The first bidirectional threaded rod 303 is threaded inside the threaded hole, and the guide rod 308 is movably fitted inside the guide hole. A worm gear 309 is fixedly connected to the first bidirectional threaded rod 303. The storage slots are used to store and limit the movement of the extension plate 301. At the same time, the first moving block 304 moves smoothly along the guide rod 308 through the guide hole.

[0045] In this invention, a worm gear 310 is rotatably connected to one side of the balance plate 1. The worm gear 310 meshes with a worm wheel 309 for transmission. A first gear 311 is fixedly connected to the worm gear 310. A first motor 312 is fixedly connected to one side of the balance plate 1. A second gear 313 is fixedly connected to the output shaft of the first motor 312. One side of the second gear 313 meshes with the first gear 311 for transmission. When the first motor 312 starts, it drives the second gear 313 to rotate through its output shaft, and at the same time, it meshes with the first gear 311, thereby driving the worm gear 310 to rotate synchronously. The rotation of the worm gear 310 drives the worm wheel 309 to mesh for transmission, and the rotation of the worm wheel 309 drives the rotation of the first bidirectional threaded rod 303.

[0046] In this invention, the clamping and fixing mechanism 4 includes a second bidirectional threaded rod 401 rotatably connected to the back of the second arc-shaped placement frame 302. A third bidirectional threaded rod 408 is rotatably connected to the back of the first arc-shaped placement frame 2 at the location corresponding to the second bidirectional threaded rod 401. A connecting sleeve 409 is fixedly connected to both ends of the third bidirectional threaded rod 408 at the location corresponding to the second bidirectional threaded rod 401. The second bidirectional threaded rod 401 is movably sleeved inside the connecting sleeve 409. A limiting block 411 is fixedly connected to one end of the second bidirectional threaded rod 401. A limiting groove is formed on the connecting sleeve 409 at the location corresponding to the limiting block 411. The limiting block 411 is movably sleeved inside the limiting groove. The rotation of the third bidirectional threaded rod 408 drives the rotation of the connecting sleeve 409. The rotation of the connecting sleeve 409 synchronously drives the synchronous rotation of the second bidirectional threaded rod 401 through the limiting block 411.

[0047] In this invention, a second moving block 402 is threaded onto the second bidirectional threaded rod 401 and the third bidirectional threaded rod 408, respectively. A first traction plate 403 is rotatably connected to the second moving block 402. A connecting block 404 is rotatably connected to the first traction plate 403. A second traction plate 405 is rotatably connected to the connecting block 404. An arc-shaped clamping plate 406 is rotatably connected to the other end of the second traction plate 405. The arc-shaped clamping plate 406 is movably fitted onto the top ends of the first arc-shaped placement frame 2 and the second arc-shaped placement frame 302. A stop block 407 is provided inside the arc-shaped clamping plate 406. A stop groove is provided at one end of the first arc-shaped placement frame 2 and the second arc-shaped placement frame 302 corresponding to the stop block 407. The stop block 407 is movably fitted into the stop groove. Inside, the synchronous rotation of the second bidirectional threaded rod 401 and the third bidirectional threaded rod 408 respectively drives the second moving block 402 to move in opposite directions. The movement of the second moving block 402 drives the first traction plate 403 to swing, and at the same time drives the connecting block 404 to move. The movement of the connecting block 404 drives the arc-shaped clamping plate 406 to move along the top of the second arc-shaped placement frame 302 and the first arc-shaped placement frame 2 through the second traction plate 405. This allows for adjustment according to the longitudinal dimensions of the actually installed trough solar mirror, and at the same time, clamps and fixes the trough solar mirror placed on the second arc-shaped placement frame 302 and the first arc-shaped placement frame 2, facilitating the rapid installation of the trough solar mirror.

[0048] In this invention, a first pulley 410 is fixedly connected to one side of the third bidirectional threaded rod 408, a second motor 412 is fixedly connected to the back of the balance plate 1, a second pulley 413 is fixedly connected to the output shaft of the second motor 412, and the same track 414 is connected to the outside of the second pulley 413 and the first pulley 410. When the second motor 412 starts, it drives the second pulley 413 to rotate through the output shaft, and at the same time drives the first pulley 410 to rotate through the track 414. The rotation of the first pulley 410 drives the third bidirectional threaded rod 408 to rotate synchronously.

[0049] In this invention, the flipping mechanism 5 includes a support plate 501. A first rotating block is fixedly connected to the top of the support plate 501. A push rod motor 502 is fixedly connected to the first rotating block. A second rotating block is fixedly connected to the output end of the push rod motor 502. One end of the second rotating block is rotatably connected to the balance plate 1. A connecting rod 503 is fixedly connected to the back of the balance plate 1. Multiple support frames 6 are rotatably connected in an array on the connecting rod 503. A reinforcing frame 7 is fixedly connected between the support frames 6. The support plate 501 is fixedly connected between two support frames 6. When the push rod motor 502 is started, it drives the second rotating block to move through its output end, thereby causing the balance plate 1 to flip around the connecting rod 503, thereby adjusting the angle of the equipment.

[0050] Equipment assembly process:

[0051] Foundation fixing: Fix the support frame 6 to the concrete foundation with expansion bolts, ensuring that the distance between adjacent support frames 6 is 1.8m; weld the reinforcing frame 7 between the support frames 6 to form a stable support frame.

[0052] Balance plate installation: Pass the connecting rod 503 through the bearing seat at the top of the support frame 6, and then weld the back of the balance plate 1 to the connecting rod 503 to ensure that the balance plate 1 is placed horizontally.

[0053] Assembly of the flipping mechanism: Fix the support plate 501 between two adjacent support frames 6, connect the two ends of the push rod motor 502 to the first rotating block and the second rotating block respectively, then fix the first rotating block on the support plate 501 and fix the second rotating block on the side of the balance plate 1.

[0054] Extension mechanism assembly: Insert the extension plate 301 into the storage slots on both sides of the balance plate 1, install the first bidirectional threaded rod 303 and the guide rod 308 inside the balance plate 1, and sleeve the first moving block 304 on the first bidirectional threaded rod 303 and the guide rod 308; rotatably connect the two ends of the telescopic fence 305 to the first moving block 304 and the slider 306 respectively, and sleeve the slider 306 on the slide rod 307 of the extension plate 301; finally install the worm 310, the first gear 311, the first motor 312 and the second gear 313 to ensure that the worm 310 meshes with the worm wheel 309.

[0055] Clamping and fixing mechanism assembly: Install the third bidirectional threaded rod 408 on the back of the first arc-shaped placement frame 2, install the second bidirectional threaded rod 401 on the back of the second arc-shaped placement frame 302, and insert the second bidirectional threaded rod 401 into the third bidirectional threaded rod.

[0056] Working principle: In use: When it is necessary to expand the horizontal mounting surface, the first bidirectional threaded rod 303 rotates, driving the first moving blocks 304 at both ends to move towards each other, causing the telescopic fence 305 to extend; when the telescopic fence 305 extends, it pushes the slider 306 to slide along the sliding rod 307, thereby causing the extension plate 301 to extend out of the storage slot of the balance plate 1, and the second arc-shaped placement frame 302 moves synchronously with the extension plate 301 to realize the expansion of the horizontal mounting surface; conversely, when the first bidirectional threaded rod 303 rotates in the opposite direction, the telescopic fence 305 retracts, pulling the extension plate 301 back into the storage slot, completing the reduction of the horizontal mounting surface;

[0057] Clamping process: After the condenser lens is placed on the first arc-shaped placement frame 2 and the second arc-shaped placement frame 302, the third bidirectional threaded rod 408 rotates, which drives the second bidirectional threaded rod 401 to rotate synchronously through the connecting sleeve 409 and the limiting block 411; the second bidirectional threaded rod 401 and the third bidirectional threaded rod 408 drive their respective second moving blocks 402 to move towards each other, causing the first traction plate 403 to swing, which in turn pushes the connecting block 404 to move; the connecting block 404 pulls the arc-shaped clamping plate 406 along the stop groove through the second traction plate 405 until the rubber buffer layer of the arc-shaped clamping plate 406 is tightly attached to the edge of the condenser lens, completing the clamping and fixing; conversely, when the second moving block 404 moves in the opposite direction, the arc-shaped clamping plate 406 is released, which facilitates the disassembly and replacement of the condenser lens;

[0058] Angle adjustment process: When it is necessary to adjust the sun-facing angle of the condenser, the output end of the push rod motor 502 extends or retracts, pushing the second rotating block to drive the balance plate 1 to rotate around the linkage rod 503; according to the signal fed back by the solar azimuth sensor (such as a combination of GPS positioning and photosensitive sensor), the push rod motor 502 can achieve precise stroke control, so that the angle adjustment accuracy of the condenser reaches ±0.1°, ensuring that the condenser is always facing the sun and maximizing the light-gathering efficiency.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
