Description

Technical Field

[0001] This invention relates to the field of bracket technology, and more specifically to a quick-installation bracket for photovoltaic panels with adjustable tilt angle. Background Technology

[0002] Adjustable tilt photovoltaic (PV) panel quick-installation brackets are PV support structures that combine rapid assembly with dynamic tilt adjustment. The core of these brackets is modular design, pre-punched holes, and snap-fit ​​mechanisms for rapid on-site assembly. For tilt adjustment, two methods are available: either each bracket can be equipped with an independent motor (single-drive independent control, flexible adjustment, adaptable to complex terrain), or a unified centralized motor (using linkages, gears, or wireless synchronous drive to synchronously drive the entire row / panel of brackets, resulting in lower cost and better synchronization). These methods drive mechanical transmission mechanisms (such as push rods, lead screws, and gears) to rotate the PV panels around their axis, adapting to seasonal changes in solar altitude angle and improving power generation efficiency.

[0003] Existing adjustable tilt photovoltaic (PV) panel quick-installation brackets can achieve rapid on-site assembly and tilt angle adjustment via an independent motor per bracket or a unified motor throughout the area, all employing a rigid mechanical transmission structure for adjustment. However, PV panels are mostly deployed in complex outdoor environments such as mountain slopes, Gobi deserts, open rooftops, and farmland, constantly exposed to harsh conditions such as strong winds, gusts, heavy rain, blizzards, sandstorms, and fluctuating day-night temperatures. These purely rigid mechanical adjustment structures are extremely rigid and lack buffer margins. When there is wind disturbance or external impact, the rigid tensile, compressive, and vibration stresses generated during adjustment, operation, and positioning and locking are directly transmitted to the PV panel surface, easily causing internal microcracks in the cells, deformation of the module frame, and micro-damage to the glass panel surface. Long-term repeated exposure to wind loads and mechanical tension can also exacerbate cracking of the PV module sealant and delamination, directly damaging the PV panel's structural lifespan and causing a series of problems such as power generation attenuation, light leakage, water seepage, and insulation safety hazards. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides an adjustable tilt angle photovoltaic panel quick-installation bracket, which effectively solves the problems of existing purely rigid motor-adjustable photovoltaic quick-installation brackets lacking buffering, easily transmitting external stress in harsh outdoor environments, causing damage to photovoltaic modules, power generation attenuation, safety hazards, and shortened service life.

[0014] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. Through the air compressor, metering component, diversion component, compression component, and pressure stabilizing component in the pneumatic-hydraulic mechanism, external air is used to compress and draw in hydraulic oil, thereby controlling the lifting and lowering of the corresponding lifting component to achieve angle adjustment of the photovoltaic panel. Specifically, the air compressor, rotating forward, draws in external air and transmits it to the metering component, which in turn acts on the compression component. This causes the compression component to descend within the metering component, compressing the hydraulic oil inside. The compressed hydraulic oil, after being stabilized by the pressure stabilizing component, is then delivered to the corresponding square tube, increasing the amount of hydraulic oil delivered to the corresponding lifting component, thus extending the lifting component. When the air compressor rotates in reverse, it draws air from the metering component, which also acts on the compression component to achieve the same effect. The extrusion component rises within the metering component to draw hydraulic oil from its interior, thereby reducing the amount of hydraulic oil delivered to the corresponding lifting component via the square tube. This facilitates the descent of the lifting component. Utilizing hydraulic oil as the power transmission medium, the buffering and pressure-equalizing properties of liquids avoid the rigid force mode of traditional motor-driven mechanical transmission. Furthermore, the hydraulic oil adjustment inherently provides shock absorption, force relief, and pressure equalization, mitigating the impact stress caused by strong outdoor winds and temperature fluctuations. This ensures that the photovoltaic panel experiences gentle and uniform force under angle adjustments and daily wind conditions, preventing rigid pulling, extrusion, and resonance. This fundamentally avoids issues such as component microcracks, frame deformation, adhesive layer cracking, and glass damage, enhancing overall anti-aging and anti-interference capabilities, protecting the photovoltaic module structure for a long time, and ensuring stable power generation efficiency.

[0015] 2. The pressure-limiting and releasing components and the pressure-reducing component in the infusion mechanism divert hydraulic oil when it is delivered to a pair of lifting components through a square tube. This ensures that the lifting components receive the same amount of hydraulic oil evenly and simultaneously locks the hydraulic oil acting on the lifting components. The pressure-limiting and releasing component opens at a predetermined pressure to allow the hydraulic oil to increase or decrease within the lifting components, and closes when the predetermined pressure is not reached to lock the hydraulic oil within the lifting components. The pressure-limiting and releasing component also diverts the delivered hydraulic oil to the corresponding positions of the pair of lifting components. The pressure-reducing component utilizes… By utilizing its own deformation under limited pressure, the photovoltaic panel expands itself through deformation when subjected to strong winds. The pressure-relief module can also expand slightly by its own controllable deformation when strong winds impact the photovoltaic panel. Relying on the flexible buffering characteristics of the hydraulic medium, it absorbs the instantaneous impact force and vibration stress brought by the wind pressure, thereby achieving pressure relief and energy dissipation. This ensures that the angle adjustment of multiple sets of lifting modules is uniform and the positioning is reliable, eliminating the problems of unilateral force and tilt deviation. It can also flexibly resolve the sudden loads generated by strong outdoor winds, avoid module pulling, frame compression, and cell microcracks caused by hydraulic hard lifting, and improve the wind resistance stability and structural safety of the support.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, 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, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] The present invention will be further described below with reference to embodiments.

[0021] Example: Refer to Figures 1 to 18 An adjustable tilt angle photovoltaic panel quick-installation bracket includes: A control base 1 is fixedly connected to a mounting base 11 on one side of the control base 1 in the width direction, and protective plates 12 are fixedly connected to both sides of the upper end face of the mounting base 11 in the length direction. The gas-liquid mechanism 2 includes two air compressors 21 and two metering components 23 disposed on the upper end face of the control base 1. Each metering component 23 has a diversion component 24 disposed on its inner top and the diversion component 24 is connected to the corresponding air compressor 21. Each metering component 23 has a compression component 25 and a pressure stabilizing component 26 disposed sequentially from top to bottom on its inner wall. Two square tubes 27 are fixedly connected to the center position of the upper end face of the mounting base 11 in the length direction. Angle adjustment mechanism 3, multiple angle adjustment mechanisms 3 are arranged in a linear array on the upper end face of the mounting base 11, and two square tubes 27 are located at the center of the angle adjustment mechanism 3. The infusion mechanism 4 corresponds to the angle adjustment mechanism 3 in number. Each infusion mechanism 4 includes two pressure limiting and release components 41 disposed on the upper surface of the mounting base 11 and located on both sides of the angle adjustment mechanism 3. The two pressure limiting and release components 41 are connected to two square tubes 27. Pressure relief components 42 are provided on both sides of each pressure limiting and release component 41 on the mounting base 11.

[0022] The forward rotation of the air compressor 21 in the gas-liquid mechanism 2 draws in outside air and transmits it to the metering component 23, which in turn acts on the squeezing component 25, causing the squeezing component 25 to descend within the metering component 23, thereby controlling the rise of the angle adjustment mechanism 3. Conversely, the reverse rotation of the air compressor 21 draws in air from the metering component 23 and acts on the squeezing component 25, causing the squeezing component 25 to rise within the metering component 23, thereby controlling the descent of the angle adjustment mechanism 3. The infusion mechanism 4 uses the pressure limiting and releasing component 41 to lock the angle adjustment mechanism 3 after it has been raised or lowered, while the pressure relief component 42 is used to release pressure when the angle adjustment mechanism 3 is subjected to excessive pressure.

[0023] Reference Figures 1 to 5 A controller is provided on the upper end face of the control base 1, and a detector 22 is fixedly connected to the upper end face of the control base 1, and the detector 22 is electrically connected to the controller. Two air compressors 21 are fixedly connected side by side to the upper surface of the control base 1 away from the mounting base 11, and two metering components 23 correspond one-to-one with the two air compressors 21.

[0024] The metering component 23 includes an outer casing 231 fixedly connected to the upper surface of the control base 1 near the mounting base 11. A limiting frame 232 is fixedly connected to the upper part of the outer casing 231. A measuring ruler 233 is fixedly connected to the inner wall of the outer casing 231 below the limiting frame 232. A first pressure device 234 and a delivery pipe 235 are fixedly connected to the two sides of the lower part of the outer casing 231, respectively. The other end of the delivery pipe 235 is connected to the input end of the corresponding square pipe 27, and the first pressure device 234 is electrically connected to the controller.

[0025] The detector 22 is used to detect the surrounding environment and transmit the detection information to the controller. The air compressor 21 provides corresponding suction by rotating in both directions. The limiting frame 232 in the metering component 23 is used to limit the highest position of the squeezing component 25 sliding and rising inside the outer box 231, while the measuring ruler 233 is used to provide the position of the squeezing component 25 inside the outer box 231.

[0026] Reference Figure 4 , Figure 6 The diversion assembly 24 includes a top plate 241 fixedly connected to the top of the outer casing 231. A diverter 243 is fixedly connected to the side of the top plate 241 facing the inside of the outer casing 231. An air pipe 242 is fixedly connected to the input end of the diverter 243, and the other end of the air pipe 242 passes through the top plate 241 and is connected to the output end of the corresponding air compressor 21.

[0027] The air pipe 242 in the diversion assembly 24 is used to receive the air pressure delivered by the air compressor 21, while the diverter 243 is used to divert the air pressure, so that the air pressure can be fully distributed inside the outer casing 231.

[0028] Reference Figure 4 , Figure 7 , Figure 8 The extrusion assembly 25 includes a piston 251 that is airtightly slidably connected to the inner wall of the outer casing 231 located below the limiting frame 232. Hydraulic oil is stored inside both the outer casing 231 located below the piston 251 and inside the square tube 27. A rubber block 252 is fixedly connected to the side of the piston 251 facing the measuring scale 233, and the rubber block 252 and the measuring scale 233 slide airtightly. Multiple gas-gathering hoods 253 are fixedly connected in a rectangular array to the side of the piston 251 facing the limiting frame 232. A reader 254 is fixedly connected to the side of the piston 251 away from the gas-gathering hood 253. The reader 254 corresponds to the measuring scale 233 and is electrically connected to the controller.

[0029] The piston 251 in the extrusion assembly 25 moves up and down within the outer casing 231 to deliver or draw hydraulic oil from the square tube 27 into the outer casing 231. The rubber block 252 in the piston 251 further seals the piston 251 as it passes through the measuring scale 233. The scale on the measuring scale 233 is read by the reader 254 to obtain the current position of the piston 251 within the outer casing 231. Based on the current position of the piston 251 within the outer casing 231, the current amount of hydraulic oil in the outer casing 231 is further determined.

[0030] Reference Figure 4 , Figure 9 The pressure stabilizing component 26 includes a honeycomb plate 261 fixedly connected to the inside of the outer casing 231 and located below the measuring ruler 233. The honeycomb plate 261 divides the inside of the outer casing 231 into a pressurizing area and a depressurizing area. A storage box 262 is embedded on the side of the honeycomb plate 261 facing the piston 251. The storage box 262 corresponds to the position of the reader 254. The first pressure device 234 and the delivery pipe 235 correspond to the positions of the depressurizing area.

[0031] The honeycomb plate 261 in the pressure stabilizing component 26 is used to buffer and divert the hydraulic oil in the pressurized area, while the storage box 262 is used to store the reader 254 when the piston 251 descends to contact the honeycomb plate 261.

[0032] Reference Figures 10 to 11 The angle adjustment mechanism 3 includes two pairs of lifting components 31 symmetrically arranged on the upper surface of the mounting base 11 and located between two protective plates 12. Each pair of lifting components 31 includes a connecting seat 311 fixedly connected to the upper surface of the mounting base 11. The upper surface of the connecting seat 311 is fixedly connected to multiple sections of retractable rods 313. An angle adjustment component 314 is fixedly connected to the telescopic end of the multiple sections of retractable rods 313. The adjustment ends of each telescopic angle adjustment component 314 are fixedly connected to a photovoltaic mounting frame 32. A photovoltaic panel 100 is installed in the photovoltaic mounting frame 32. A horizontal detector 33 is fixedly connected to the center position of the photovoltaic mounting frame 32. The horizontal detector 33 is electrically connected to the controller. A second pressure device 312 is fixedly connected to the side of one of the connecting seats 311. The second pressure device 312 is electrically connected to the controller.

[0033] The connecting seat 311 of the lifting component 31 in the angle adjustment mechanism 3 receives the hydraulic oil delivered or drawn by the corresponding square tube 27, and further delivers it to the multi-section retractable rod 313, thereby causing the multi-section retractable rod 313 to extend or retract accordingly, while the level detector 33 is used to detect the tilt of the current photovoltaic mounting frame 32.

[0034] Reference Figures 13 to 15 Two pressure-limiting and release components 41 correspond to the positions of two pairs of lifting components 31 and two square tubes 27 respectively. The pressure-limiting and release component 41 includes a housing 411 fixedly connected to the upper end face of the mounting base 11 and located between two connecting seats 311. A release structure 412 is provided at the center of the housing 411. The release structure 412 includes a partition plate 4121 fixedly connected to the center of the housing 411. Multiple connecting holes 4122 are provided in a rectangular array on the side of the partition plate 4121. Each connecting hole 4122 is airtightly slidably connected to a blocking block 4123. Multiple perforated boxes 4124 are fixedly connected to both sides of the partition plate 4121, and the perforated boxes 4124 correspond to the connecting holes 4122. Pressure rods 4125 are fixedly connected to both sides of the blocking block 4123, and the other end of the pressure rod 4125 is fixedly connected to the side of the perforated box 4124 facing the blocking block 4123. The input end of the housing 411 is fixedly connected to the input pipe 414, and the other end of the input pipe 414 is connected to one of the corresponding square pipes 27. The output end of the housing 411 is fixedly connected to the diversion valve 413, and the two output ends of the diversion valve 413 are respectively fixedly connected to the interconnecting pipe 4131.

[0035] The internal structure of the housing 411 is separated by the release structure 412 in the pressure limiting and release assembly 41. The blocking block 4123 in the release structure 412 is used to block the connecting hole 4122. Only when the pressure of the hydraulic oil in the square tube 27 overcomes the pressure value of the pressure rod 4125 itself will the pressure rods 4125 on both sides of the blocking block 4123 be compressed and extended. At this time, the blocking block 4123 will disengage from the connecting hole 4122, thereby opening the connecting hole 4122.

[0036] Reference Figures 16 to 18 The pressure relief assembly 42 includes a pressure relief box 421 fixedly connected to the mounting base 11 near the upper surface of the housing 411. An elastic buffer block 422 is fixedly connected to the center of the pressure relief box 421. A guide structure 423 is provided at the center of the elastic buffer block 422. The guide structure 423 includes two fixed tubes 4231 fixedly connected to the inner walls on both sides of the pressure relief box 421. The two fixed tubes 4231 are respectively connected to the input end and the output end of the pressure relief box 421. An elastic tube 4332 is fixedly connected between the two fixed tubes 4231 and contacts the interior of the elastic buffer block 422. The other end of the interconnecting tube 4131 is connected to the input end of the pressure relief box 421. A connecting tube 424 is fixedly connected to the output end of the pressure relief box 421 and is connected to the input end of the nearby connecting seat 311.

[0037] The hydraulic oil transmitted from the interconnecting pipe 4131 is received by the fixed pipe 4231 and the elastic pipe 4332 in the pressure relief assembly 42. The elastic expansion of the elastic pipe 4332 is limited by the elastic buffer block 422. The hydraulic oil through the fixed pipe 4231 and the elastic pipe 4332 is delivered to the multi-section retraction rod 313. The specific operating principle of this embodiment is as follows: Step 1: First, the detector 22 on the base 1 is controlled to detect outdoor environmental data such as solar azimuth, altitude angle, wind speed, and wind pressure in real time. This data provides a data source for adjusting the tilt angle of the photovoltaic panel 100 and transmits the detection signal to the controller. Meanwhile, the horizontal detector 33 corresponding to the photovoltaic mounting frame 32 simultaneously detects the current tilt angle and levelness of the photovoltaic mounting frame 32. Thus, the controller combines the solar position data to determine the optimal solar reception tilt angle of the photovoltaic panel 100, compares it with the current actual tilt angle, and generates adjustment commands to raise, lower, or fine-tune the tilt angle. At the same time, it sends targeted forward, reverse, or stop commands to two independent air compressors 21 (one can be controlled individually or both can be controlled simultaneously). Meanwhile, the first pressure device 234 detects the pressure value of the hydraulic oil in the corresponding metering component 23, and the second pressure device 312 detects the pressure value of the hydraulic oil in the multi-section retraction rod 313, continuously feeding back pressure data to the controller.

[0038] Among them, two air compressors 21 and two metering components 23 correspond one-to-one to form two independent pneumatic-hydraulic systems. The controller can independently control the forward and reverse rotation and working time of each air compressor 21, and thus independently control the hydraulic oil extrusion delivery or negative pressure back suction of the corresponding metering component 23, providing the power basis for multi-angle tilt adjustment. Specifically, it is divided into two working states: tilt angle raising / fine adjustment and tilt angle lowering / fine adjustment. The two working states have the same principle and can be executed independently. 1. Tilt angle lifting / fine adjustment (air compressor 21 rotates forward, corresponding to the extension of a pair of lifting components 31): At this time, the controller controls the corresponding air compressor 21 to rotate forward, and draws in and filters outside air from the air compressor 21. The compressed air is sent along the air pipe 242 to the distributor 243. The distributor 243 evenly and vertically discharges the compressed air into the space above the piston 251 inside the outer casing 231, avoiding uneven local air pressure that could cause the piston 251 to tilt and jam. When the compressed air contacts the air-gathering shroud 253 on the upper surface of the piston 251, the air-gathering shroud 253 gathers the dispersed air pressure into a concentrated pressure that is vertically downward, thereby pushing the piston 251 along the outer casing 231. The piston 251 slides down the inner wall of the outer box 231 in an airtight manner. During the downward movement of the piston 251, its rubber block 252 is in close contact with the measuring scale 233 on the inner wall of the outer box 231 and slides in an airtight manner to make up for the gap between the measuring scale 233 and the piston 251, ensuring the airtightness of the air pressure chamber inside the outer box 231 and preventing air pressure leakage. At the same time, the reader 254 on the lower end face of the piston 251 is aligned with the measuring scale 233 to read the scale value in real time and transmit it to the controller. The controller calculates the downward movement distance of the piston 251 through the scale change, and then determines the volume of hydraulic oil that is squeezed. When the piston 251 slides down and squeezes the hydraulic oil in the outer box 231, the hydraulic oil flows to the honeycomb plate 261 after being squeezed. The honeycomb-shaped through holes of the honeycomb plate 261 disperse the concentrated high pressure of the piston 251 into a uniform low pressure. At the same time, it filters out the tiny air bubbles in the hydraulic oil to prevent air bubbles from entering and causing pressure fluctuations. The hydraulic oil that has been stabilized and defoamed enters the pressure relief zone of the outer box 231. At this time, the first pressure device 234 detects the hydraulic oil pressure in real time, and the hydraulic oil is also transported to the corresponding square pipe 27 along the delivery pipe 235. Since the square tube 27 is pre-filled with hydraulic oil, when new hydraulic oil is injected, the pressure of the hydraulic oil in the tube increases rapidly and linearly, providing sufficient power for the subsequent opening of the pressure limiting and releasing component 41.

[0039] As the hydraulic oil pressure inside the square tube 27 continues to rise, when the pressure exceeds the preset pressure limit threshold of the pressure rod 4125 in the pressure relief assembly 41, the high-pressure hydraulic oil enters the housing 411 along the input pipe 414 and directly acts on the block 4123. The hydraulic oil pressure overcomes the elastic support force of the pressure rod 4125, pushing the block 4123 to slide airtightly along the connecting hole 4122 towards the diverter valve 413. At this time, the pressure rod 4125 on the input pipe 414 side is stretched and extended, and the pressure rod 4125 on the diverter valve 413 side is squeezed. When the pressure is compressed, the connecting hole 4122 is fully opened, and the hydraulic oil enters the diversion valve 413 inside the housing 411 and is diverted. The diverted hydraulic oil enters the pressure relief box 421 of the pressure relief component 42 along the interconnect pipe 4131. It first passes through the fixed pipe 4231 at the input end of the pressure relief box 421 and then enters the elastic pipe 4332 (the elastic pipe 4332 is made of flexible material and fits inside the elastic buffer block 422). At this time, the elastic pipe 4332 expands slightly with the flow of hydraulic oil, completing the initial pressure relief and preventing the high-pressure hydraulic oil from directly impacting the lifting component 31. Hydraulic oil passes through the elastic tube 4332, then through the fixed tube 4231 and the connecting tube 424 at the output end of the pressure relief box 421, and enters the connecting seat 311 of the lifting assembly 31. The hydraulic oil continuously enters the multi-section retractable rod 313 (hydraulic-driven telescopic structure with airtight seals between sections), pushing it to extend synchronously and equidistantly along the telescopic direction. The telescopic end of the multi-section retractable rod 313 drives the angle adjustment component 314 to provide angle support, ultimately pushing the photovoltaic mounting frame 32 and the photovoltaic panel 100 to slowly lift, achieving tilt angle lifting / fine adjustment.

[0040] 2. Tilt angle reduction / fine adjustment (air compressor 21 reverses, corresponding to the retraction of the other pair of lifting components 31): At this time, the controller controls the corresponding air compressor 21 to reverse, drawing air from the upper part of the piston 251 inside the outer casing 231 through the air pipe 242 and the distributor 243, creating a stable negative pressure in the air pressure chamber above the piston 251. The upward force generated by this negative pressure pulls the piston 251 to slide airtightly along the inner wall of the outer casing 231. As the piston 251 slides upward, a stable negative pressure is formed in the depressurization zone and pressurization zone inside the outer casing 231, generating a continuous and uniform suction force on the hydraulic oil in the square pipe 27 through the delivery pipe 235. At this time, the hydraulic oil in the square tube 27 is subjected to suction, and the pressure drops rapidly, forming a negative pressure state. When the negative pressure value (absolute value) exceeds the preset pressure limit threshold of the pressure rod 4125, it provides sufficient power for the subsequent reverse opening of the pressure limit release component 41 and the back suction of hydraulic oil. During the upward sliding of the piston 251, the reader 254 still reads the scale of the measuring ruler 233 in real time and feeds back the upward sliding distance to the controller. The controller determines the volume of back suctioned hydraulic oil by controlling the reverse reversal time of the air compressor 21.

[0041] The negative pressure suction in the square tube 27 is transmitted along the input tube 414 to the end face of the block 4123 in the housing 411. The suction overcomes the elastic support force of the pressure rod 4125 and pulls the block 4123 along the connecting hole 4122 to the side of the input tube 414 in an airtight manner. At this time, the pressure rod 4125 on the side of the input tube 414 is squeezed and compressed, and the pressure rod 4125 on the side of the diversion valve 413 is stretched and extended. The connecting hole 4122 is fully opened, and the hydraulic oil in the lifting assembly 31 is subjected to negative pressure suction and flows along the connecting tube 424 → the fixed tube 4231 of the pressure relief assembly 42, the elastic tube 4332 → the interconnecting tube 4131. After being equalized by the diversion valve 413, it enters the square tube 27 along the housing 411 and the input tube 414, ensuring that the two multi-section retraction rods 313 of a single pair of lifting assemblies 31 return oil in equal amounts, and preventing the photovoltaic mounting frame 32 from tilting.

[0042] As the hydraulic oil in the multi-section retractable rod 313 is continuously and equally drawn back, the volume of hydraulic oil in the rod decreases. Under the combined action of its own structural gravity and negative pressure suction, it contracts synchronously and at equal intervals along the extension and retraction direction. The contraction end of the multi-section retractable rod 313 drives the angle adjustment component 314 to lower the angle, and the photovoltaic mounting frame 32 and photovoltaic panel 100 slowly descend, realizing the reduction / fine adjustment of the tilt angle.

[0043] Special Note: The core difference between tilt angle raising / fine-tuning and tilt angle lowering / fine-tuning lies in the reverse rotation direction of the air compressor 21. This causes the components, pressure changes, and hydraulic oil flow directions of the entire process of the gas-liquid mechanism 2, liquid delivery mechanism 4, and angle adjustment mechanism 3 to be completely opposite, ultimately achieving the extension and retraction of the multi-section retraction rod 313. The specific differences are as follows: 1) When the tilt angle is raised / fine-tuned, the controller controls the corresponding air compressor 21 to rotate forward, drawing in filtered air from the outside and delivering it to the distributor 243 through the air pipe 242. After the air is evenly distributed, the piston 251 is pushed down the outer box 231 in an airtight manner, squeezing the hydraulic oil in the outer box 231. The hydraulic oil is then stabilized and defoamed through the honeycomb plate 261 and enters the square tube 27 through the delivery pipe 235, so that positive pressure is formed in the square tube 27 and exceeds the pressure limit threshold of the pressure rod 4125. This pushes the block block 4123 to slide to the side of the diversion valve 413 to open the connecting hole 4122. After the hydraulic oil is divided equally by the diversion valve 413, it enters the elastic tube 4332 of the pressure relief component 42 through the interconnecting pipe 4131 to complete the initial pressure relief. Then, it enters the multi-section shrink rod 313 through the connecting pipe 424 and the connecting seat 311, pushing the multi-section shrink rod 313 to extend synchronously and equidistantly, driving the angle adjustment component 314 and the photovoltaic mounting frame 32 to lift, thereby increasing the tilt angle of the photovoltaic panel by 100°.

[0044] 2) When the tilt angle is reduced / fine-tuned, the controller controls the corresponding air compressor 21 to reverse, drawing air from above the piston 251 inside the outer casing 231 through the air pipe 242 and the distributor 243. This creates a negative pressure inside the outer casing 231, pulling the piston 251 upwards along the limiting frame 232 for airtight sealing. The negative pressure inside the outer casing 231 is transmitted to the square pipe 27 through the delivery pipe 235, creating a negative pressure inside the square pipe 27. The negative pressure value exceeds the pressure limit threshold of the pressure rod 4125, pulling the blockage block 4123 towards the input pipe 4. 14. The connecting hole 4122 is slid open on one side. The hydraulic oil in the multi-section retractable rod 313 enters the pressure relief component 42 through the connecting seat 311 and the connecting pipe 424 under the negative pressure suction. Then, it is drawn back to the square pipe 27 through the interconnecting pipe 4131 and the diversion valve 413. Finally, it flows back to the outer box 231 along the conveying pipe 235. The multi-section retractable rod 313 retracts synchronously and at equal intervals under the combined action of its own gravity and negative pressure suction, which drives the angle adjustment component 314 and the photovoltaic mounting frame 32 to descend, thereby reducing the tilt angle of the photovoltaic panel by 100°.

[0045] When the photovoltaic panel 100 reaches the preset optimal tilt angle, the controller controls all air compressors 21 to stop working, no longer generating compressed air or negative pressure suction. At this time, the air pressure in the outer casing 231 no longer changes, thereby causing the piston 251 to lose pressure / tension, stop sliding and maintain its current position. At this time, the hydraulic oil no longer exerts a pushing / pulling force on the blocking block 4123 of the pressure limiting release component 41, and the pressure rod 4125, relying on its own elastic restoring force, pushes the blocking block 4123 to slide along the connecting hole 4122, re-airtightly embedding it in the connecting hole 4122, achieving the sealing of the connecting hole 4122, cutting off all transmission of hydraulic oil. At this time, the hydraulic oil in the multi-section retractable rod 313 of the lifting component 31 is sealed and locked, and the multi-section retractable rod 313 maintains its current extended / retracted state. The tilt angle of the photovoltaic mounting frame 32 is fixed, and it will not shift even if it is slightly disturbed by external forces.

[0046] Step 2: Since the photovoltaic panel 100 is deployed outdoors, when it encounters strong winds, gusts, or sudden wind pressure, the instantaneous impact force of the wind pressure on the photovoltaic panel 100 will be transmitted to the multi-section retractable rod 313 through the photovoltaic mounting frame 32 and the angle adjustment component 314. This causes the hydraulic oil pressure inside the rod to increase instantaneously. The high-pressure hydraulic oil flows in reverse along the connecting pipe 424 into the pressure relief box 421 of the pressure relief component 42. The reverse-flowing high-pressure hydraulic oil enters the elastic tube 4332, thereby generating a squeezing force on the elastic tube 4332 and pushing the elastic tube 4332 to undergo a slight expansion. When the elastic tube 4332 expands, it squeezes the external elastic buffer block 422, causing the elastic buffer block 422 to undergo elastic deformation simultaneously. This converts the high-pressure impact energy of the hydraulic oil into the deformation energy of the elastic buffer block 422. When the wind pressure impact disappears, the elastic buffer block 422, relying on its own elastic restoring force, squeezes the elastic tube 4332 to contract and reset. The high-pressure hydraulic oil in the elastic tube 4332 flows back to the multi-section retraction rod 313, and the pressure relief component 42 returns to its initial state.

[0047] Special Note: 1. Through the controllable deformation of the elastic tube 4332 and the elastic buffer block 422, the hard impact stress directly acting on the photovoltaic panel 100 is converted into flexible deformation energy, which dissipates the instantaneous impact force and vibration stress brought by wind pressure, avoids the stress being directly transmitted to the surface of the photovoltaic panel 100, and prevents problems such as cell microcracks, module frame extrusion deformation, micro-damage to the glass panel surface, and sealant cracking.

[0048] 2. The elastic buffer block 422 is preset with a specific elastic limit pressure, for example, this limit pressure value is set to 0.8MPa, thereby constraining the elastic expansion range of the elastic tube 4332. After the photovoltaic mounting bracket 32 ​​and the photovoltaic panel 100 exert their own weight on the multi-section retractable rod 313, the hydraulic oil inside the rod will only form a normal stable pressure far below the limit pressure. After this pressure is transmitted to the elastic tube 4332, it cannot push it to deform, nor will it cause elastic deformation of the elastic buffer block 422. In addition, during this process, the release structure 412 in the pressure limiting release component 41 always forms a stable lock on the hydraulic oil, blocking the arbitrary transmission of hydraulic oil. To ensure that the tilt angle of the photovoltaic panel 100 does not change under normal circumstances, only when the photovoltaic panel 100 is subjected to additional instantaneous impact forces such as strong winds, gusts, or sudden wind pressure outdoors, the impact force will be quickly transmitted to the multi-section retractable rod 313 through the photovoltaic mounting frame 32 and the angle adjustment component 314. This causes the hydraulic oil pressure inside the rod to increase instantly and exceed the 0.8MPa elastic limit pressure of the elastic buffer block 422. The high-pressure hydraulic oil then flows in the opposite direction along the connecting pipe 424 into the elastic pipe 4332, pushing the elastic pipe 4332 to expand slightly while squeezing the elastic buffer block 422 to undergo elastic deformation, thereby flexibly dissipating the impact stress brought by the wind pressure. When the wind pressure disappears, the elastic buffer block 422 returns to its original state by its own elastic restoring force, squeezing the elastic tube 4332 to contract and reset. The high-pressure hydraulic oil in the elastic tube 4332 flows back to the multi-section retraction rod 313. During this process, the release structure 412 of the pressure limiting release component 41 remains locked to the hydraulic oil, with no hydraulic oil overflowing or flowing back. Finally, it pushes the multi-section retraction rod 313 back to its original state, causing the photovoltaic panel 100 to accurately return to its original tilt angle, ensuring the normal solar power generation of the photovoltaic panel 100.

[0049] Step 3: When the outdoor wind speed / wind pressure exceeds the safety threshold, and the second pressure device 312 detects that the hydraulic oil pressure in the multi-section retraction rod 313 reaches the maximum pressure that the photovoltaic panel 100 can withstand, the controller controls the two air compressors 21 to start the reverse mode at the same time, and perform synchronous and strong negative pressure suction on the outer box 231 of the two metering components 23, so that a high-intensity stable negative pressure is formed in the outer box 231, providing sufficient power for the rapid back suction of all hydraulic oil. At this time, a high-intensity negative pressure is formed in both square tubes 27, and the negative pressure value is much greater than the pressure limit threshold of the pressure rod 4125, which pushes the block 4123 of the pressure limit release component 41 to open in the reverse direction at the same time. Hydraulic oil in the lifting components 31 of all angle adjustment mechanisms on the mounting base 11 flows quickly and evenly back to the corresponding square pipe 27 through the pressure relief component 42, interconnecting pipe 4131, diverting valve 413, housing 411, and input pipe 414, and then flows back to the outer box 231 along the conveying pipe 235. When the hydraulic oil in all the multi-section retractable rods 313 is quickly drained, they completely retract to their shortest state under the combined action of their own structural gravity and negative pressure suction. After the multi-section retractable rods 313 are completely retracted, they drive the angle adjustment component 314 and the photovoltaic mounting frame 32 to fall back, so that the photovoltaic panel 100 quickly returns to a horizontal state and remains flush with the protective plates 12 on both sides of the mounting base 11.

[0050] Special note: After the photovoltaic panel 100 is horizontally reset, the windward area is reduced (only 1 / 3 to 1 / 2 of the tilted state), which reduces the impact force of strong winds on the photovoltaic panel 100 and avoids serious structural damage such as the photovoltaic panel 100 being overturned by strong winds, frame deformation, and glass breakage, thus achieving the ultimate emergency protection for the photovoltaic module.

[0051] When the outdoor wind speed / pressure drops below the safety threshold, and the second pressure device 312 detects that the hydraulic oil pressure has returned to normal, the controller can restart the gas-liquid mechanism 2 according to the solar position data, and adjust the photovoltaic panel 100 to the optimal tilt angle according to the tilt angle lifting / fine-tuning process in the first step, so as to restore the normal power generation state.
