Description

Technical Field

[0001] This invention relates to the field of solar photovoltaic module technology, specifically to a dual-axis solar photovoltaic automatic tracking support mechanism. Background Technology

[0002] Solar photovoltaic (PV) power generation, as a core form of clean and renewable energy utilization, has been widely applied in centralized PV power plants, distributed grid-connected PV systems, and outdoor special PV power supply scenarios. To maximize the photoelectric conversion efficiency of PV modules, the industry generally adopts dual-axis automatic tracking brackets to replace fixed brackets and single-axis tracking brackets. Through dynamic adjustment of azimuth and pitch angles, the PV modules are aligned with the direction of sunlight in real time, significantly improving the overall power generation gain of the PV system. Dual-axis photovoltaic (PV) tracking brackets primarily rely on support mechanisms to achieve overall load-bearing capacity, rotation adjustment, and attitude positioning. They are the core structural element ensuring tracking accuracy, equipment stability, and lifespan. Currently, most existing dual-axis PV tracking support mechanisms employ fixed truss welded structures or simple hinged shaft support structures, coupled with worm gear and gear transmission components to achieve dual-axis tracking adjustment. These traditional support structures still have many technical shortcomings in practical applications and cannot meet the demands of large-scale PV power plants for high precision, long lifespan, and low maintenance. First, existing support structures lack sufficient overall structural rigidity and load-bearing capacity. Most are integrated fixed support structures, capable only of providing a single rotating support function, lacking adaptive buffering and stress-distributing structures. Outdoor photovoltaic power stations are constantly exposed to complex and harsh conditions such as strong winds, heavy rains, blizzards, and sandstorms. The support structures must continuously withstand wind pressure, snow loads, and the equipment's own weight. Stress easily concentrates in core load-bearing parts such as shafts and hinge points. Under long-term alternating loads, structural deformation, shaft wear, and loosening of connectors are prone to occur. This not only directly reduces the tracking and alignment accuracy of photovoltaic modules, causing a decrease in power generation efficiency, but in severe cases, it can also lead to safety hazards such as bracket tilting and module detachment. Traditional support mechanisms are difficult to disassemble and maintain. They are mostly integral welded and fixed structures, and the support wear parts and transmission components cannot be disassembled and replaced individually. Once the core support parts are worn or deformed, the entire support equipment needs to be disassembled or even replaced. This results in high operation and maintenance costs and low maintenance efficiency, which greatly increases the later operation costs of photovoltaic power plants and restricts the large-scale promotion and application of dual-axis photovoltaic tracking equipment.

[0013] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, by setting an automatic tracking motor loading component as the loading position of the tracking drive motor and setting an adjustment drive motor as the power device for longitudinal adjustment, the automatic tracking motor loading component can make fine position adjustments from top to bottom when it loads the driving tracking motor part, which facilitates timely and flexible position adjustment and thus benefits the tracking adjustment of photovoltaic modules.

[0014] 2. In this invention, after the arch plate of the settling component rotates away from the bottom of the shift fork plate, the driven gear will not separate from the driving gear in a short time, thereby ensuring that the driving gear has sufficient driving time for the driven gear, further ensuring that the settling screw can rotate a sufficient number of turns, so that the range of downward movement of the automatic tracking motor loading component is large, thereby making the adjustment range of the tracking part after loading also large.

[0015] 3. In this invention, during the downward reset of the driven gear, the friction ring located at its bottom is simultaneously driven to reset downward as well, gradually approaching the top of the brake pad. Until the driven gear resets downward and separates from the driving gear, the bottom of the friction ring at the bottom of the driven gear contacts the top of the brake pad, thereby limiting the rotation of the friction ring, the driven gear, and the sinker screw, preventing unnecessary rotation of the sinker screw, which in turn prevents unnecessary positional shift of the automatic tracking motor loading components during operation, ensuring the stability of the operation.

[0016] Furthermore, the structure of this invention is an internal structure, with corresponding gears and drive mechanisms, and external protective mechanisms are provided. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1 - Figure 11 The technical solution provided by the present invention specifically includes the following embodiments: Example 1: A dual-axis solar photovoltaic automatic tracking bracket support mechanism includes a top plate 1, two left and right distributed support frames 101 are fixedly installed at the bottom of the top plate 1, a bottom plate 102 is fixedly installed at the bottom of the two support frames 101, a turnover component 2 is provided at the bottom of the top plate 1, an automatic tracking motor loading component 3 is provided at the bottom of the top plate 1, a sinking component 4 is provided at the bottom of the top plate 1, and an auxiliary loading component 5 is provided at the top of the bottom plate 102, with the auxiliary loading component 5 located at the lower end of the turnover component 2; The turnover component 2 includes a turnover vertical shaft 201 rotatably installed inside the top plate 1. The turnover vertical shaft 201 movably passes through the top and bottom of the top plate 1. A flange 202 is fixedly installed at the bottom of the turnover vertical shaft 201. The bottom of the flange 202 is connected to the added structure by bolts. A drive gear 203 is fixedly installed on the outer wall of the turnover vertical shaft 201. A driven pulley 204 is fixedly installed at the top of the turnover vertical shaft 201. A position adjustment drive motor 205 is fixedly installed on the left side of the top plate 1. A drive pulley 206 is fixedly installed on the output shaft of the position adjustment drive motor 205. A power belt 207 is sleeved between the drive pulley 206 and the driven pulley 204. The automatic tracking motor loading component 3 includes a tracking drive motor loading platform 301, which is located at the bottom rear of the drive gear 203. Two telescopic rods 302 are slidably installed inside the tracking drive motor loading platform 301, which pass through the front and back of the tracking drive motor loading platform 301. There are two telescopic rods 302, and a loading end plate 303 is fixedly installed at the front of the two telescopic rods 302. A first spring 304 is sleeved around the periphery of each telescopic rod 302. The first spring 304 is fixedly installed between the tracking drive motor loading platform 301 and the loading end plate 303. A ball sleeve 305 is fixedly installed on the upper part of the side of the loading end plate 303 away from the tracking drive motor loading platform 301. A rolling ball 306 is rolled inside the ball sleeve 305. A loading auxiliary positioning protruding ball head 307 is fixedly installed on the lower part of the side of the loading end plate 303 away from the tracking drive motor loading platform 301. The loading auxiliary positioning protruding ball head 307 is located at the bottom of the ball sleeve 305. In this embodiment, the output shaft of the adjustment drive motor 205 drives the active pulley 206 to rotate slowly. The rotation of the active pulley 206 drives the driven pulley 204 to rotate via the power belt 207. The rotation of the driven pulley 204 drives the flange 202 to rotate together via the rotating vertical shaft 201. This further drives the flange 202, which is fixedly installed at the bottom, to rotate together. During the rotation, the thrust applied to the ball 306 is transmitted to the two telescopic rods 302 through the ball sleeve 305 and the loading end plate 303. This causes the two telescopic rods 302 to move along the loading platform 301 of the tracking drive motor. The two first springs 304 are compressed. The rebound force of the first springs 304 pushes the telescopic rods 302, the loading end plate 303, the ball sleeve 305, and the ball 306. This further drives the loading auxiliary positioning convex ball head 307 to swing together, thereby achieving position adjustment, that is, achieving position adjustment of the automatic tracking motor loading component 3 and its loading structure.

[0021] Example 2: The settling component 4 includes a settling screw 401 and a settling platform 402. The settling screw 401 is rotatably mounted on the bottom of the top plate 1 and is located at the rear of the rotating vertical shaft 201. The settling platform 402 is movably located around the settling screw 401. An internal threaded sleeve 403 is fixedly installed at the bottom of the settling platform 402. The inner wall of the internal threaded sleeve 403 is threadedly connected to the outer wall of the settling screw 401. The settling platform 402 is located at the rear of the tracking drive motor loading platform 301, and the front of the settling platform 402 is fixedly connected to the back of the tracking drive motor loading platform 301. A plurality of key blocks 404 distributed at equal angles are fixedly installed on the upper part of the outer wall of the settling screw 401. A driven gear 405 is slidably installed on the outer wall of the settling screw 401. The driven gear 405 is located at the rear end bottom of the driving gear 203. The inner wall of the driven gear 405 is provided with multiple keyways 406 distributed at equal angles. The inner wall of the keyway 406 is slidably connected to the outer wall of the key block 404. A retaining ring 407 is fixedly installed on the top of the driven gear 405. The outer wall of the retaining ring 407 is provided with an annular groove 408. A shift fork plate 409 is rotatably sleeved around the annular groove 408. A collar 4010 is provided at the end of the shift fork plate 409 away from the annular groove 408. The inner wall of the collar 4010 is slidably connected to the outer wall of the rotating vertical shaft 201. A mounting groove 4011 is provided through the top of the shift fork plate 409. A guide wheel 4012 is rotatably installed inside the mounting groove 4011. An arch plate 4013 is fixedly installed on the top of the driving gear 203. The settling component 4 also includes two hydraulic cylinders 4014 distributed to the left and right. The hydraulic cylinders 4014 penetrate the top and bottom of the top plate 1, and their outer walls are fixedly connected to the inner walls of the through holes in the top plate 1. An oil separator 4015 is fixedly installed in the middle of the inner wall of the hydraulic cylinder 4014. An oil passage 4016 is formed through the top of the oil separator 4015 extending downwards. A guide rod 4017 is fixedly installed on the top wall of the hydraulic cylinder 4014, extending into the oil passage 4016. A valve plate 4018 is slidably installed on the outer wall of the guide rod 4017. The bottom of the valve plate 4018 abuts against the top of the oil separator 4015, and the diameter of the valve plate 4018 is larger than the inner diameter of the oil passage 4016. The top of the cylinder 4017 is provided with multiple equally angled oil return holes 4019. A second spring 4020 is sleeved around the guide rod 4017. The second spring 4020 is fixedly installed between the top wall of the cylinder 4014 and the top of the valve plate 4018. A piston 4021 is slidably installed inside the cylinder 4014. The piston 4021 is located at the bottom of the oil separator 4015. A push rod 4022 is fixedly installed at the bottom of the piston 4021. The bottom of the push rod 4022 is fixedly connected to the top of the shift fork plate 409. A third spring 4023 is sleeved around the push rod 4022. The third spring 4023 is fixedly installed between the bottom of the piston 4021 and the bottom wall of the cylinder 4014. In this embodiment, during the rotation of the vertical shaft 201, the driving gear 203 and the arch plate 4013 rotate together. Each rotation of the arch plate 4013 pushes the shift fork plate 409 upwards, causing the shift fork plate 409 to move upwards. This upward movement of the shift fork plate 409, through its interaction with the annular groove 408, drives the driven gear 405 to move upwards. The driven gear 405 then engages with the driving gear 203. Therefore, the driving gear 203, through its engagement with the driven gear 405, drives the sinker screw 401 to rotate. The rotation of the sinker screw 401, through its threaded engagement with the internal threaded sleeve 403, pushes the sinking platform 402 downwards. The tracking drive motor loading platform 301 drives the ball sleeve 305, rolling ball 306, and loading auxiliary positioning convex ball head 307 to move downwards together. It should be noted that the upward movement of the shift fork plate 409 will cause the push rod 4022 and piston 4021 to move upwards, stretching and storing the third spring 4023. The upward movement of piston 4021 compresses the oil at its top, increasing the oil pressure in the area between piston 4021 and oil separator 4015, thus pushing valve plate 4018 upwards. The compressed oil quickly enters the top area of ​​oil separator 4015 through oil passage 4016 and the gap between the pushed-up valve plate 4018 and the top of oil separator 4015. Meanwhile, the valve... The upward movement of plate 4018 compresses the second spring 4020, storing energy. When the arch plate 4013 rotates away from the bottom of the shift fork plate 409, the rebound force of the third spring 4023 drives the piston 4021 and push rod 4022 to return downwards, causing the shift fork plate 409 to return downwards as well. Simultaneously, the rebound force of the second spring 4020 pushes the valve plate 4018 downwards, again abutting against the top of the oil separator plate 4015. This causes the oil at the top of the oil separator plate 4015 to flow back to the bottom area of ​​the oil separator plate 4015 under the negative pressure created by the downward movement of the piston 4021. Since the diameter of the oil return hole 4019 is small, the oil at the top of the oil separator plate 4015... The oil cannot flow back to the bottom area of ​​the oil separator 4015 in a short time, causing the piston 4021 to slowly reset downwards. This further drives the shift fork plate 409 to slowly reset downwards via the push rod 4022. The shift fork plate 409 drives the driven gear 405 to slowly move downwards via the annular groove 408. In other words, after the arch plate 4013 rotates away from the bottom of the shift fork plate 409, the driven gear 405 will not separate from the driving gear 203 in a short time. This ensures that the driving gear 203 has enough driving time for the driven gear 405, further ensuring that the sinker screw 401 can rotate a sufficient number of turns, so that the downward movement distance of the automatic tracking motor loading component 3 is not too small.

[0022] Furthermore, a friction ring 4025 is fixedly installed at the bottom of the driven gear 405. Two rear-mounted lifting rods 4026 are fixedly installed at the bottom left and bottom right ends of the top plate 1. A support plate 4027 is fixedly installed at the bottom of the two rear-mounted lifting rods 4026. A brake pad 4028 is fixedly installed at the top of the support plate 4027. The brake pad 4028 is located at the bottom of the friction ring 4025, and the top of the brake pad 4028 abuts against the bottom of the friction ring 4025. When the driven gear 405 is resetting downwards, it synchronously drives the position... The friction ring 4025 at its bottom is reset downwards together, gradually approaching the top of the brake pad 4028, until the driven gear 405 resets downwards and separates from the driving gear 203. Then, the bottom of the friction ring 4025 at the bottom of the driven gear 405 contacts the top of the brake pad 4028, thereby limiting the rotation of the friction ring 4025, the driven gear 405 and the sinker screw 401, preventing unnecessary rotation of the sinker screw 401, which in turn prevents unnecessary adjustment of the detection height of the automatic tracking motor loading component 3.

[0023] Furthermore, two sliding holes 4029 distributed to the left and right are opened through the top of the settling platform 402. Two smooth rods 4024 distributed to the left and right are fixedly installed between the top plate 1 and the bottom plate 102. The outer wall of the smooth rod 4024 is slidably connected to the inside of the sliding hole 4029. Through the sliding connection between the smooth rod 4024 and the sliding hole 4029, the smoothness of the settling platform 402 moving up and down can be improved.

[0024] Example 3: The auxiliary loading component 5 includes a telescopic sleeve 501 fixedly installed on the top of the base plate 102. A telescopic column 502 is slidably installed on the inner wall of the telescopic sleeve 501. A transition plate 503 is rotatably installed on the bottom of the telescopic column 502. A fourth spring 504 is fixedly installed between the bottom of the transition plate 503 and the top of the base plate 102. A tray 505 is fixedly installed on the top of the telescopic column 502. A positioning frustum 507 is detachably installed on the top of the tray 505. A positioning groove 5013 is opened on the top of the positioning frustum 507. Two slots 506 are provided on the lower part of the outer wall of the tray 505. The two slots 506 are symmetrically distributed about the center of the tray 505. Two sliding grooves 508 are provided on the upper part of the outer wall of the positioning frustum 507. The two sliding grooves 508 are symmetrically distributed about the center of the positioning frustum 507. A slider 509 is slidably installed inside each of the two sliding grooves 508. A connecting plate 5010 is fixedly installed at the bottom of each slider 509 at the far end. A latch 5011 is fixedly installed on the lower part of the side of each connecting plate 5010 that is close to each other. The latch 5011 is engaged inside the slot 506. A fifth spring 5012 is fixedly installed on the side of each slider 509 that is close to each other. The end of the fifth spring 5012 that is away from the slider 509 is fixedly connected to the inner wall of the sliding groove 508. By pressing down the positioning frustum 507, the positioning frustum 507 pushes the telescopic column 502 and the adapter plate 503 downward along the inner wall of the telescopic sleeve 501 via the tray 505, causing the fourth spring 504 to compress. Then, the structure to be loaded is fixed to the bottom of the flange 202 with bolts. The downward pressure of the positioning frustum 507 is removed, and the rebound force of the fourth spring 504 pushes the adapter plate 503, telescopic column 502, tray 505 and positioning frustum 507 upward, so that the positioning groove 5013 is fitted on the outside of the structure to be loaded, thereby positioning the bottom of the structure to be loaded. In addition, with the joint action of the flange 202, the stability of the structure to be loaded is ensured, and the structure to be loaded will not swing during rotation.

[0025] During the rotation of the vertical shaft 201, the driving gear 203 and the arch plate 4013 rotate together. Each rotation of the arch plate 4013 pushes the shift fork plate 409 upwards, causing it to move upwards. This upward movement of the shift fork plate 409, through its interaction with the annular groove 408, drives the driven gear 405 upwards. The driven gear 405 then meshes with the driving gear 203. Therefore, the driving gear 203, through its meshing with the driven gear 405, drives the sinker screw 401 to rotate. The rotation of the sinker screw 401, through its threaded engagement with the internal threaded sleeve 403, pushes the sinking platform 402 downwards. The sinking platform 402 is connected to the two smooth rods 4024 via two sliding holes 4029. The downward movement of the settling platform 402, driven by the tracking motor, causes the ball sleeve 305, the rolling ball 306, and the loading auxiliary positioning convex ball head 307 to move downwards together, thus adjusting the loading height of the tracking motor. It is important to note that when the shift fork plate 409 moves upwards, it causes the push rod 4022 and piston 4021 to move upwards, stretching and storing the third spring 4023. The upward movement of the piston 4021 compresses the oil at its top, increasing the oil pressure in the area between the piston 4021 and the oil separator 4015, which in turn pushes the valve plate 4018 upwards. The compressed oil then flows through the oil passage 4016 and the upward-pushed valve plate 4018 against the oil separator 4015. The oil quickly enters the top area of ​​the oil separator 4015 through the gap between the parts. The upward movement of the valve plate 4018 compresses the second spring 4020, storing energy. When the arch plate 4013 rotates away from the bottom of the shift fork plate 409, the rebound force of the third spring 4023 drives the piston 4021 and push rod 4022 to return downwards, causing the shift fork plate 409 to return downwards as well. Simultaneously, the rebound force of the second spring 4020 pushes the valve plate 4018 downwards, again abutting against the top of the oil separator 4015. This causes the oil at the top of the oil separator 4015 to flow back to the bottom area of ​​the oil separator 4015 through the return oil orifice 4019 under the negative pressure created by the downward movement of the piston 4021. The return oil orifice 4019 has a small diameter. Therefore, the oil at the top of the oil separator 4015 cannot flow back to the bottom area of ​​the oil separator 4015 in a short time, causing the piston 4021 to slowly reset downwards. This further drives the shift fork plate 409 to slowly reset downwards via the push rod 4022. The shift fork plate 409 drives the driven gear 405 to slowly move downwards via the annular groove 408. In other words, after the arch plate 4013 rotates away from the bottom of the shift fork plate 409, the driven gear 405 will not separate from the driving gear 203 in a short time. This ensures that the driving gear 203 has enough driving time for the driven gear 405, further ensuring that the sinker screw 401 can rotate a sufficient number of turns, so that the downward movement distance of the automatic tracking motor loading component 3 is not too small.
