Description

Technical Field

[0001] This invention belongs to the field of photovoltaic tracking bracket technology, and particularly relates to an adaptive folding photovoltaic tracking bracket. Background Technology

[0002] A photovoltaic tracking bracket is an intelligent support structure that uses electromechanical drive to make photovoltaic panels follow the sun like a sunflower. Compared with fixed brackets, it can significantly increase power generation.

[0003] Once the existing photovoltaic tracking bracket is fixedly installed, it can drive the photovoltaic panel to rotate according to the direction of the sun's movement, and it will always remain in a flat state. When encountering severe weather such as hail, it will be directly hit by heavy objects such as hail, which will damage the photovoltaic panel surface. At the same time, during heavy snowfall, the photovoltaic panel surface will be covered by thick snow and unable to work. During the long period of time when the snow melts, the photovoltaic panel surface cannot absorb light energy, resulting in significant losses. In order to avoid the above situations, an adaptive folding photovoltaic tracking bracket is provided. Summary of the Invention

[0004] This invention provides an adaptive folding photovoltaic tracking bracket, which aims to solve the problems of existing photovoltaic tracking brackets. After being fixedly installed, the photovoltaic panels can rotate to track the direction of the sun's movement, but they always remain in a flat state. When encountering severe weather such as hail, they are directly hit by heavy objects such as hail, which damages the photovoltaic panels. At the same time, during heavy snowfall, the photovoltaic panels are covered by thick snow and cannot work. During the long period of snowmelt, the photovoltaic panels cannot absorb light energy, resulting in significant losses.

[0005] The present invention is implemented as follows: an adaptive folding photovoltaic tracking bracket includes a fixing component: an adjustment component is provided on the inner wall of the fixing component, a support frame mechanism is connected to the inner wall of the adjustment component, a side protection component is provided on the inner wall of the support frame mechanism, and a cleaning component is provided on the outer wall of the support frame mechanism. The load-bearing frame mechanism includes a connecting shaft and an inner fixing plate. Two single-frame assemblies are rotatably connected to the outer wall of the connecting shaft. Multiple photoelectric sensors are fixedly connected to both sides of the single-frame assemblies. Multiple folding motors are fixedly connected to the outer wall of the inner fixing plate. The output shaft of the folding motor is fixedly connected to a connecting short rod through a coupling. A transmission gear is fixedly connected to one end of the connecting short rod. The single-frame assembly includes a frame, an inner support frame is fixedly connected to the inner wall of the frame, a shaft connecting cylinder is fixedly connected to one side of the frame, and a photovoltaic fixing installation hole is opened on one side of the frame; The inner wall of the shaft connecting cylinder is provided with multiple internal toothed grooves arranged in a ring, and these internal toothed grooves are used in conjunction with the transmission gear. In use, the folding motor is started and controlled, which drives the transmission gear to rotate. Because multiple internal tooth grooves work in conjunction with the transmission gear, the two frames rotate along the connecting shaft, thereby folding the two single frame components together.

[0006] Preferably, the frame is rotatably connected to the connecting shaft, and the side protection assembly is embedded in the inner wall of the frame; The side protection assembly includes an inner connecting corner plate that is slidably connected to the inner wall of the frame and an inner rotating shaft that is rotatably connected to the inner wall of the frame. A plurality of protective short rods are fixedly connected to one side of the inner connecting corner plate, and the protective short rods penetrate one side of the frame. A pressure plate is fixedly connected to the outer wall of the inner rotating shaft, and one end of the pressure plate is located below the inner connecting corner plate. A pressure rod is fixedly connected to the outer wall of the frame, and a pressure groove is provided on the inner wall of the frame. The pressure rod and the pressure groove are used in conjunction, and the pressure groove is located above the side of the pressure plate away from the inner connecting corner plate. When the two single frame components are unfolded, the inner connecting corner plate and the protective short rod slide down, and the protective short rod falls into the frame. When the two single-frame components are folded, the opposing pressure rods and pressure grooves work together. The pressure rods are inserted into the pressure grooves and press against the side of the pressure plate away from the inner connecting corner plate. The pressure plate rotates along the inner rotation axis, pushing the inner connecting corner plate and the protective short rod upward. The protective short rod slides out of the frame and is located in the gap between the two single-frame components, providing protection from the side of the single-frame components to prevent birds and small animals from crawling into the two single-frame components when folded.

[0007] Preferably, the outer wall of the frame is fixedly connected with a mating lock head and a mating lock rod, and the mating lock head and the mating lock rod are correspondingly mated; The matching lock head includes a fixed lock head that is fixedly connected to the frame, a sliding lock block that is slidably connected to the outer wall of the fixed lock head, and a return spring embedded in the inner wall of the sliding lock block; The return spring has a damper on its inner wall, and the sliding lock block and the fixed lock head are connected by the return spring and the damper. Figure 6 As shown, the sliding lock block is an approximately elliptical lock block, the upper end of the fixed lock head is set with a slope, and a locking block is set at the upper end of the lock rod; During use, when the two single-frame components are folded and overlapped, the locking rod first enters between the fixed lock head and the sliding lock block. At this time, the fixed lock head and the locking rod are locked together, forming a locking relationship. The two single-frame components are locked. Then, the folding motor is controlled to rotate one side of the single-frame component in the same direction. The locking rod continues to move forward, and the locking block at the head of the locking rod slides to the other end of the sliding lock block. Under the action of the return spring, the sliding lock block returns to its original position and fits tightly against the fixed lock head. At this time, the folding motor is controlled to rotate in the opposite direction, and the locking rod smoothly slides away from the fixed lock head and the sliding lock block. The two single-frame components are then unlocked and unfolded.

The auxiliary water tank includes a small water tank body, with a water inlet hole on the lower side of one side of the small water tank body. A pressure probe is installed on the inner wall of the small water tank body, and the first water replenishment pump is connected to the small water tank body through the water inlet hole. When the water in the small water tank is used, the water level drops, and the pressure probe value changes accordingly. Once the pressure probe value drops to the set value, the first water replenishment pump is started to automatically replenish the small water tank. The water inlet and the first water supply pump are used together. The output shaft of the receiver is fixedly connected to a winding rod via a coupling. A pull rope is fixedly connected to the outer wall of the winding rod, and a cleaning brush head is fixedly connected to one end of the pull rope. The inner wall of the frame is provided with an inner limiting groove. The two sides of the cleaning brush head are slidably connected to the inner wall of the inner limiting groove.

A pressure switch is fixedly connected to the inner wall of the frame. The output end of the second water pump is connected to the inner water channel through a hose. During use, start and control the receiving and discharging motor to drive rotation and retract the cleaning brush head. The cleaning brush head slides along the inner wall of the inner limit groove, which can wipe and clean the upper surface of the photovoltaic panel and improve the light energy absorption efficiency of the photovoltaic panel. When the cleaning brush head slides to the end of its travel on one side, it presses against the pressure switch, triggering the switch and starting the second water pump. This pump draws water from the auxiliary water tank and sprays it onto the photovoltaic panel through the internal water channel and spray nozzles, thus cleaning the photovoltaic panel in conjunction with the cleaning brush head.

The regulating motor is fixedly installed inside the mounting base. In use, firstly, based on the light-sensing signal from the photoelectric sensor, the position of the sun is determined, and the control motor is started and activated to drive the main rotating rod to rotate, which in turn drives the carrier frame mechanism and the photovoltaic panels installed in the carrier frame mechanism to rotate, so as to achieve light tracking and improve the absorption efficiency of the photovoltaic panels.

[0012] Preferably, the fixing component further includes a base, an inner connecting block is fixedly connected to the top of the base, and a plurality of connecting bolts are threadedly connected to the inner wall of the mounting base, with the connecting bolts spirally inserted into the inner connecting block; In use, first, fix the base to the installation ground. By rotating multiple connecting bolts, the position between the mounting base and the base can be fixed.

[0013] Preferably, the top of the base is fixedly connected with a plurality of inner limiting strips, and the inner limiting strips fit into the mounting base; The multiple inner limit bars allow for adjustment of the relative distance between the base and the mounting base by rotating the length of the multiple connecting bolts inserted into the base, thereby adjusting the height of the upper support frame mechanism and the photovoltaic panels installed in the support frame mechanism.

[0014] Compared with the prior art, the embodiments of this application have the following main advantages: The load-bearing frame mechanism, serving as the core installation and driving unit for photovoltaic panels, fundamentally solves the problem of traditional fixed or flat supports failing to protect themselves in severe weather through its unique folding structure design. Its core benefit lies in achieving adaptive switching between the photovoltaic panel's working state—flat state, protective state, and folded state. By setting up and using the support frame mechanism and the side protection components together: the linkage design of the support frame mechanism and the side protection components cleverly utilizes the folding action to trigger the generation of a lateral physical barrier, which solves the problem that gaps are formed between the two photovoltaic panels in the folded state, which may be caused by birds or small animals crawling in and causing secondary damage such as short circuits, corrosion or nesting. By setting up and using the support frame mechanism and cleaning components in a coordinated manner, the passive recovery after severe weather and the active cleaning of daily maintenance are integrated, solving the problem of dirt on the panel surface and dust accumulation affecting power generation efficiency after snow melts, and realizing the linkage and intelligentization of cleaning and protection. By using the fixed components: The fixed components provide a stable and flexibly adjustable installation base for the entire adaptive tracking bracket, solving the problems of poor adaptability of photovoltaic brackets to different terrains and installation environments and the inability to easily adjust the foundation height; By setting and using the control components: The control components are the key hub that connects the two core functions of "tracking" and "receiving and distributing". They solve the problems of separation between traditional tracking and protection mechanisms, complex control and slow response, and realize unified and coordinated control of precise solar power generation and rapid emergency protection.

Multiple photoelectric sensors 304 are fixedly connected to both sides of the single frame assembly 301. Multiple folding motors 305 are fixedly connected to the outer wall of the inner fixing plate 303. The output shaft of the folding motor 305 is fixedly connected to a connecting short rod through a coupling. A transmission gear 306 is fixedly connected to one end of the connecting short rod. The single-frame assembly 301 includes a frame 3011, an inner support frame 3013 is fixedly connected to the inner wall of the frame 3011, a shaft connecting cylinder 3012 is fixedly connected to one side of the frame 3011, and a photovoltaic fixing installation hole 30111 is opened on one side of the frame 3011. The inner wall of the shaft connecting cylinder 3012 is provided with multiple internal toothed grooves arranged in a ring, and the multiple internal toothed grooves are used in conjunction with the transmission gear 306. In use, the folding motor 305 is started and controlled to drive the transmission gear 306 to rotate. Because multiple internal tooth grooves work in conjunction with the transmission gear 306, the two frames 3011 are driven to rotate along the connecting shaft 302, thereby folding the two single frame components 301 together.

[0020] The frame 3011 is rotatably connected to the connecting shaft 302, and the side protection component 4 is embedded in the inner wall of the frame 3011; The side protection assembly 4 includes an inner connecting corner plate 401 that is slidably connected to the inner wall of the frame 3011 and an inner rotating shaft 403 that is rotatably connected to the inner wall of the frame 3011. A plurality of protective short rods 402 are fixedly connected to one side of the inner connecting corner plate 401, and the protective short rods 402 penetrate one side of the frame 3011. A pressure plate 404 is fixedly connected to the outer wall of the inner rotating shaft 403, and one end of the pressure plate 404 is located below the inner connecting corner plate 401. A pressure rod 3017 is fixedly connected to the outer wall of the frame 3011, and a pressure groove 3018 is provided on the inner wall of the frame 3011. The pressure rod 3017 and the pressure groove 3018 are used in conjunction, and the pressure groove 3018 is located above the pressure plate 404 on the side away from the inner connecting corner plate 401. When the two single frame components 301 are unfolded, the inner connecting corner plate 401 and the protective short rod 402 slide down, and the protective short rod 402 falls into the frame 3011. When the two single-frame components 301 are folded, the opposing pressure rods 3017 and pressure grooves 3018 work together. The pressure rods 3017 are inserted into the pressure grooves 3018 and press on the side of the pressure plate 404 away from the inner connecting corner plate 401. The pressure plate 404 rotates along the inner rotating shaft 403, pushing the inner connecting corner plate 401 and the protective short rod 402 upward. The protective short rod 402 slides out of the frame 3011 and is located in the gap between the two single-frame components 301, providing protection from the side of the single-frame components 301 to prevent birds and small animals from crawling into the two single-frame components 301 in the folded state.

[0021] The outer wall of the frame 3011 is fixedly connected with a locking head 3015 and a locking rod 3016, and the locking head 3015 and the locking rod 3016 are correspondingly fitted together. The locking head component 3015 includes a fixed locking head 3015-a fixedly connected to the frame 3011, a sliding locking block 3015-b slidably connected to the outer wall of the fixed locking head 3015-a, and a return spring 3015-c embedded in the inner wall of the sliding locking block 3015-b. The return spring 3015-c has a damper on its inner wall, and the sliding lock block 3015-b and the fixed lock head 3015-a are connected by the return spring 3015-c and the damper. Figure 6 As shown, the sliding lock block 3015-b is an approximately elliptical lock block, and the upper end of the fixed lock head 3015-a is set with a slope, and a locking block is set at the upper end of the locking rod 3016. In use, when the two single-frame components 301 are folded and overlapped, the locking rod 3016 first enters between the head of the fixed lock head 3015-a and the sliding lock block 3015-b. At this time, the fixed lock head 3015-a and the locking rod 3016 are locked together, forming a locking relationship. The two single-frame components 301 are locked. The folding motor 305 is then used to control one side of the single-frame component 301 to rotate in the same direction. The locking rod 3016 continues to move forward, and the locking block at the head of the locking rod 3016 slides to the other end of the sliding lock block 3015-b. Under the action of the return spring 3015-c, the sliding lock block 3015-b returns to its original position and fits tightly against the fixed lock head 3015-a. At this time, the folding motor 305 is used to rotate in the opposite direction, and the locking rod 3016 smoothly slides away from the fixed lock head 3015-a and the sliding lock block 3015-b. The two single-frame components 301 are then unlocked and unfolded.

[0022] The cleaning component 5 includes a main water tank 501, a receiver / discharger 504, and a secondary water tank 503. A first water replenishment pump 502 is installed on the top of the main water tank 501, and a second water replenishment pump 507 is fixedly connected to the outer wall of the secondary water tank 503. The auxiliary water tank 503 is fixedly installed on the back side of the frame 3011; The auxiliary water tank 503 includes a small water tank body 5031. A water inlet hole 5032 is provided on the lower side of one side of the small water tank body 5031. A pressure probe 5033 is provided on the inner wall of the small water tank body 5031. The first water replenishment pump 502 is connected to the small water tank body 5031 through the water inlet hole 5032. When the water in the small water tank 5031 is used, the water level drops, and the value of the pressure probe 5033 also changes accordingly. After the value of the pressure probe 5033 drops to the set value, the first water replenishment pump 502 is started to automatically replenish water to the small water tank 5031. The inlet 5032 and the first water supply pump 502 are used together; The output shaft of the retractor 504 is fixedly connected to a winding rod via a coupling. A pull rope 505 is fixedly connected to the outer wall of the winding rod, and a cleaning brush head 506 is fixedly connected to one end of the pull rope 505. The inner wall of the frame 3011 is provided with an inner limiting slide groove 3014. The two sides of the cleaning brush head 506 are slidably connected to the inner wall of the inner limiting slide groove 3014. The inner wall of the frame 3011 is provided with an inner water channel.

In use, the start and control of the receiving and discharging motor 504 is used to drive it to rotate and retract the cleaning brush head 506. The cleaning brush head 506 slides along the inner wall of the inner limit slide groove 3014, which can wipe and clean the upper surface of the photovoltaic panel and improve the light energy absorption efficiency of the photovoltaic panel. When the cleaning brush head 506 slides to the end of its travel on one side, it presses against the pressure switch 30110, triggering the pressure switch 30110. The second water pump 507 starts, drawing water from the auxiliary water tank 503 and spraying it onto the photovoltaic panel through the internal water channel and the spray head 3019. This can be used in conjunction with the cleaning brush head 506 to clean the photovoltaic panel.

[0023] It should be noted that, since the existing photovoltaic tracking brackets are fixed and installed, they can drive the photovoltaic panels to rotate according to the direction of the sun's movement, and will always remain in a flat state, they will be directly hit by heavy objects such as hail when encountering severe weather, which will damage the photovoltaic panels. At the same time, when there is heavy snowfall, the photovoltaic panels will be covered by thick snow and unable to work. During the long period of time when the snow melts, the photovoltaic panels cannot absorb light energy, resulting in significant losses.

[0024] Specifically, in this embodiment, the solution mainly uses the setting and cooperation of the fixing component 1, the adjustment component 2, the support frame mechanism 3, the side protection component 4 and the cleaning component 5. In use, firstly, the base 102 is fixed on the installation ground. By rotating multiple connecting bolts 104, the position between the mounting base 101 and the base 102 can be fixed, and the height of the upper support frame mechanism 3 and the photovoltaic panel installed in the support frame mechanism 3 can also be adjusted. Then, the photovoltaic panel is placed on the frame 3011 and fixedly installed through the photovoltaic mounting holes 30111. The folding motor 305 is started and controlled to drive the transmission gear 306 to rotate. Because multiple internal tooth grooves cooperate with the transmission gear 306, the two frames 3011 are driven to rotate along the connecting shaft 302 respectively until the two single frame components 301 are flat. In use, the position of the sun is determined based on the light-sensing signal of the photoelectric sensor 304, and the control motor 201 is started and controlled to drive the main rotating rod 202 to rotate, which in turn drives the support frame mechanism 3 and the photovoltaic panel installed in the support frame mechanism 3 to rotate, so as to achieve light tracking and improve the absorption efficiency of the photovoltaic panel. In use, the folding motor 305 is started and controlled, which drives the transmission gear 306 to rotate. Because multiple internal tooth grooves cooperate with the transmission gear 306, the two frames 3011 are driven to rotate along the connecting shaft 302, thereby closing and folding the two single frame components 301. When the two single frame components 301 are folded, the opposing pressure rods 3017 and pressure grooves 3018 cooperate. The pressure rods 3017 are inserted into the pressure grooves 3018 and press on the side of the pressure plate 404 away from the inner connecting corner plate 401. The pressure plate 404 rotates along the inner rotating shaft 403, pushing the inner connecting corner plate 401 and the protective short rod 402 upward. The protective short rod 402 slides out of the frame 3011 and is located in the gap between the two single frame components 301, providing protection from the side of the single frame components 301 and preventing birds and small animals from crawling into the two single frame components 301 in the folded state. When the two single-frame components 301 are folded and overlapped, the locking rod 3016 first enters between the head of the fixed lock head 3015-a and the sliding lock block 3015-b. At this time, the fixed lock head 3015-a and the locking rod 3016 are locked together, forming a locking relationship. The two single-frame components 301 are locked. The folding motor 305 is used again to control one side of the single-frame component 301 to rotate in the same direction. The locking rod 3016 continues to move forward. The locking block at the head of the locking rod 3016 slides to the other end of the sliding lock block 3015-b. Under the action of the return spring 3015-c, the sliding lock block 3015-b returns to its original position and fits tightly against the fixed lock head 3015-a. At this time, the folding motor 305 is used to rotate in the opposite direction. The locking rod 3016 slides smoothly away from the fixed lock head 3015-a and the sliding lock block 3015-b. The two single-frame components 301 are unlocked and unfolded. Passive cleaning: When the two single-frame components 301 are folded and overlapped, the length of the pull rope 505 remains unchanged, and the frame 3011, under the action of gravity, the cleaning brush head 506 slides along the inner wall of the inner limiting slide groove 3014, which can wipe and clean the surface of the photovoltaic panel. Active cleaning: During use, start and control the receiving and discharging motor 504 to drive it to rotate and retract the cleaning brush head 506. The cleaning brush head 506 slides along the inner wall of the inner limit slide groove 3014 to wipe and clean the upper surface of the photovoltaic panel, thereby improving the light energy absorption efficiency of the photovoltaic panel. When the cleaning brush head 506 slides to the end of its travel on one side, it presses against the pressure switch 30110, triggering the pressure switch 30110. The second water pump 507 starts, drawing water from the auxiliary water tank 503 and spraying it onto the photovoltaic panel through the internal water channel and the spray head 3019. This can be used in conjunction with the cleaning brush head 506 to clean the photovoltaic panel.

[0025] In this embodiment, the mechanism includes two single-frame components 301 that can rotate around a connecting shaft 302. Each frame 3011 has an inner support frame 3013 and photovoltaic mounting holes 30111. The control system can instruct the folding motor 305 to drive the transmission gear 306 to mesh with the internal gear groove in the shaft connecting cylinder 3012, precisely controlling the two frames 3011 to close towards each other. This design allows the photovoltaic panels to be quickly folded from a flat state to a near-vertical or back-to-back protective state before hail or blizzards, significantly reducing the impact area and effectively preventing hail from directly hitting the panel surface and preventing large accumulation of snow. At the same time, the wind resistance of the folded structure is significantly reduced, enhancing the overall wind resistance stability of the support. After the weather improves, the mechanism can be unfolded again to resume tracking and power generation, avoiding the loss of long-term inability to work during the snowmelt period, and achieving active and adaptive physical protection for the photovoltaic panels. In this embodiment, the side protection assembly 4 includes an inner connecting corner plate 401, protective short rods 402, an inner rotating shaft 403, and a pressure plate 404. Its ingenuity lies in its complete reliance on mechanical triggering during the folding action, requiring no additional sensors or power source. When the two single-frame assemblies 301 fold together in inclement weather, the pressure rod 3017 on one frame inserts into the pressure groove 3018 on the opposite frame, directly pressing down on the distal end of the pressure plate 404. The pressure plate 404 rotates around the inner rotating shaft 403, and its proximal end pushes upward against the inner connecting corner plate 401, thereby pushing multiple protective short rods 402 out from inside the frame 3011, which stand upright in the gap between the two single-frame assemblies 301. In the folded state, these protective short rods 402 form a dense, fence-like physical barrier. Conversely, when the bracket is unfolded, the pressure rod 3017 disengages, and the inner connecting corner plate 401 and the protective short rod 402 automatically retract and hide under the action of gravity or the reset structure. This design effectively prevents small animals such as birds and rodents from perching, defecating, or gnawing on cables in the gaps of the folded photovoltaic panels without adding extra drive and control logic, ensuring electrical safety, extending the service life of the equipment, and reflecting a highly integrated and intelligent structural design concept. In this embodiment, the cleaning component 5 includes a main water tank 501, a secondary water tank 503, a retractor 504, a pull rope 505, a cleaning brush head 506, and a spray nozzle 3019. When the two single-frame components 301 are folded up in inclement weather, the relative length of the pull rope 505 remains unchanged, and the cleaning brush head 506 will automatically slide along the inner limiting groove 3014 under the action of gravity to passively wipe the surface of the folded photovoltaic panel, initially removing snow residue or dirt. Under normal tracking conditions, the system can actively start the retractor 504 to drive the cleaning brush head 506 to reciprocate. When the brush head touches the pressure switch 30110, the second water pump 507 automatically sprays water from the secondary water tank 503 through the inner water channel and the spray nozzle 3019, realizing simultaneous water spraying and brushing. The auxiliary water tank 503 is equipped with a pressure probe 5033 and a first water replenishment pump 502, which can automatically replenish water from the main water tank 501 to form a complete water circulation cleaning system. This combination not only ensures that the surface of the photovoltaic panel is in a state of high light transmittance for a long time, improving the average annual power generation efficiency, but also utilizes the folding action itself to trigger cleaning, realizing a clever design of "one fold, double protection, namely anti-impact + cleaning"; In this embodiment, the fixing component 1 consists of a base 102, a mounting base 101, a tilting bracket 103, and connecting bolts 104. The top of the base 102 is equipped with an inner connecting block 105 and multiple inner limiting strips. During installation, the base 102 is first firmly embedded in or fixed to the installation ground. Then, the mounting base 101 is precisely inserted into the base 102 via the inner limiting strips, ensuring the alignment and torsional stability of the upper and lower structures. Crucially, by rotating the multiple connecting bolts 104, the relative distance between the mounting base 101 and the base 102 can be precisely adjusted, thereby achieving stepless fine-tuning of the entire bracket and the photovoltaic panel's height above the ground. This function is highly practical: on the one hand, it can compensate for height errors during ground construction, ensuring the bracket is level; on the other hand, in areas with thick snow, a higher preset height can be used to prevent the folded photovoltaic panel from being buried by snow or contaminated by splashed mud and water. Meanwhile, the design of the inclined support 103 provides auxiliary support for the main rotating rod 202, disperses the bending moment and wind load of the upper structure, enhances the rigidity and fatigue resistance of the overall structure, and lays a solid foundation for the long-term stable operation of the control component 2 and the load-bearing frame mechanism 3. In this embodiment, the control component 2 includes a control motor 201, a main rotating rod 202, a connecting seat 204, a rear plate 205, and a support seat 206. Its beneficial effects are reflected in three aspects: First, precise tracking. The control motor 201 drives the main rotating rod 202 to rotate precisely based on the real-time light-sensing signal from the photoelectric sensor 304 on the carrier frame mechanism 3. This, in turn, drives the entire carrier frame mechanism 3 and its photovoltaic panels to track the solar azimuth angle around the clock via the support seat 206, maximizing light energy absorption efficiency. Second, structural integration. The connecting shaft 302 is rotatably connected to the support seat 206, allowing the carrier frame mechanism 3 to both revolve and track as a whole under the drive of the control component 2, and also achieve relative rotation and folding of the two single-frame components 301 through its internal folding motor 305. These two movements do not interfere with each other and are highly integrated. Third, functional support. The main water tank 501 of the cleaning component 5 and the collector / discharge motor 504 are fixedly installed on the rear plate 205. This layout optimizes the center of gravity distribution, making the rotating parts more stable during tracking, and ensuring that the water source and power required for cleaning always follow the movement of the photovoltaic panel, eliminating the need for complex pipe and cable winding devices. In short, the control component 2, as the "skeleton," organically connects the three major functional modules of tracking, collection / folding, and cleaning, ensuring that the system can quickly, reliably, and coordinately switch between normal power generation mode and emergency protection mode.

[0026] In a further preferred embodiment of the present invention, the control component 2 includes a control motor 201. The output shaft of the control motor 201 is fixedly connected to a connecting rod via a coupling. One end of the connecting rod is fixedly connected to a main rotating rod 202. A connecting seat 204 is fixedly connected to the outer wall of the main rotating rod 202. A support seat 206 is fixedly connected to the outer wall of the connecting seat 204. A rear plate 205 is fixedly connected to the inner wall of the support seat 206. A support inner rod is connected between the rear plate 205 and the connecting seat 204.

[0027] The outer wall of the connecting shaft 302 is rotatably connected to the inner wall of the support 206; The main water tank 501 and the receiver / discharger 504 are fixedly connected to the rear plate 205; The fixing component 1 includes a mounting base 101, and an inclined bracket 103 is fixedly connected to the upper end of the mounting base 101; The main rotating rod 202 is provided with ball bearings 203 at both ends, and the two ends of the main rotating rod 202 are rotatably connected to the mounting base 101 and the inclined bracket 103 through the ball bearings 203. The regulating motor 201 is fixedly installed inside the mounting base 101. In use, firstly, based on the light-sensing signal from the photoelectric sensor 304, the position of the sun is determined, and the control motor 201 is started and controlled to drive the main rotating rod 202 to rotate, which in turn drives the support frame mechanism 3 and the photovoltaic panel installed in the support frame mechanism 3 to rotate, so as to achieve light tracking and improve the absorption efficiency of the photovoltaic panel.

[0028] The fixing component 1 also includes a base 102, an inner connecting block 105 is fixedly connected to the top of the base 102, and a plurality of connecting bolts 104 are threadedly connected to the inner wall of the mounting base 101, and the connecting bolts 104 are spirally inserted into the inner connecting block 105. In use, first, the base 102 is fixed to the installation ground. By rotating multiple connecting bolts 104, the position between the mounting base 101 and the base 102 can be fixed.

[0029] Multiple inner limiting strips are fixedly connected to the top of the base 102, and the inner limiting strips fit into the mounting base 101. The multiple inner limit bars allow for adjustment of the relative distance between the base 102 and the mounting base 101 by rotating the length of the multiple connecting bolts 104 inserted in the middle, thereby adjusting the height of the upper support frame mechanism 3 and the photovoltaic panels installed in the support frame mechanism 3.
