Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and particularly to a flexible connection method for photovoltaic panels in a mountain photovoltaic power station. Background Art

[0002] As the core component of a solar power generation system, a photovoltaic panel directly converts solar energy into electrical energy through the photovoltaic effect and is widely used in fields such as rooftop power stations, ground power stations, and distributed energy systems. Its typical structure consists of multiple solar cell units encapsulated in a glass or polymer material protective layer and peripherally reinforced by a metal frame to ensure mechanical strength and environmental tolerance. In mountainous areas such as cold or snowy regions, the power generation efficiency of photovoltaic panels is significantly affected by environmental factors, and the power generation loss caused by snow cover is particularly prominent.

[0003] Currently, the installation of photovoltaic panels in related technologies mainly relies on rigid connection structures, that is, the photovoltaic panels are fixed to the support structure through metal brackets, bolts, or welding methods, and a rigid splicing design without play is usually adopted between adjacent photovoltaic panels. Such rigid connection methods aim to ensure the stability of the overall structure and perform excellently in mechanical properties such as wind resistance and earthquake resistance. For example, in a common installation scheme, a photovoltaic panel array forms an immovable rigid whole through aluminum alloy guide rails and fasteners to achieve deformation control under long-term loads.

[0004] The above-mentioned related technologies have the following defects: Due to the lack of flexible adjustment ability between the photovoltaic panel and the support structure, when snow accumulates on the panel surface, it cannot effectively slide off through natural deformation or gravity, resulting in a continuous thickening of the snow layer. This will not only increase the load on the bracket and pose a risk of structural deformation, but also significantly reduce the power generation efficiency due to long-term shielding of the battery units, so it needs to be improved. Summary of the Invention

[0005] In order to promote the active shedding of snow on the photovoltaic panel, this application provides a flexible connection method for photovoltaic panels in a mountain photovoltaic power station.

[0006] The flexible connection method for photovoltaic panels in a mountain photovoltaic power station provided by this application adopts the following technical solution: A flexible connection method for photovoltaic panels in a mountain photovoltaic power station includes several columns, a pair of installation wires are arranged between adjacent columns, mounting frames are arranged on the two installation wires, the mounting frames are provided with mounting holes for the installation wires to pass through, and the photovoltaic panels are connected to the mounting frames.

[0007] By adopting the above technical solution, the photovoltaic panel is suspended on the installation line with a certain bending deformation ability. When snow accumulates, the installation line will undergo a downward bending deformation action. At the same time, by virtue of the excellent wind resources in the mountain area, the installation line will swing slightly with the airflow, further promoting the shedding of snow on the inclined surface of the photovoltaic panel, improving the power generation efficiency and reducing the bracket load.

[0008] Preferably, a rotating frame is rotatably provided at the bottom of the mounting frame. An air-driven fan blade is rotatably connected to the outside of the rotating frame. An installation cavity is provided inside the rotating frame. A driving disk is rotatably provided inside the installation cavity. The driving disk is fixedly connected to the air-driven fan blade. An impact block is slidably connected inside the installation cavity. The impact block is connected to a driving rod through a buffer member. The driving rod is rotatably provided between the driving disk.

[0009] By adopting the above technical solution, the flexible connection method of the photovoltaic panel of the mountain photovoltaic power station can utilize wind resources to promote snow shedding. Specifically, the design of the rotating frame and the air-driven fan blade at the bottom of the mounting frame enables the wind force to drive the air-driven fan blade to rotate, and then drives the driving disk to rotate. The rotation of the driving disk drives the impact block to slide back and forth in the installation cavity through the driving rod, generating a vibration effect. This vibration helps to break the adhesion between the snow and the surface of the photovoltaic panel, making it easier to slide off. At the same time, the presence of the buffer member reduces the damage to the driving rod during the impact process and improves the service life of the overall structure.

[0010] Preferably, a sliding groove is provided inside the installation cavity. The impact block is provided with a sliding rod. The sliding rod extends into the sliding groove and can slide. The side of the installation cavity has an opening, and a cover plate for covering the opening is provided on the outer wall of the rotating frame.

[0011] By adopting the above technical solution, the design of the sliding groove and the sliding rod enables the impact block to slide stably in the installation cavity, ensuring the smoothness and reliability of the movement of the impact block. At the same time, the opening design on the side of the installation cavity facilitates the inspection and maintenance of the internal structure, improving the operability and maintenance convenience of the system. The cover plate covering the opening can effectively prevent external impurities from entering the installation cavity and extend the service life of the equipment.

[0012] Preferably, a stress block is provided at the top of the installation cavity. The stress block is in clearance fit with the installation cavity. The stress block is fixedly connected to an adjusting rod. The adjusting rod is slidably connected to the rotating frame, and the rotating frame is provided with a locking member for locking the stress block.

[0013] By adopting the above technical solution, the adjusting rod passes through the top of the rotating frame and is fixedly connected to the force-bearing block, so that when the impact block reciprocates under the drive of the driving disc, the movement track of the impact block can be changed through the adjusting rod, thereby adjusting the impact strength and frequency. The design of the locking member can ensure the stable position of the force-bearing block after adjustment, and ensure the consistency and reliability of the impact effect. This design can not only effectively promote the shedding of snow, but also flexibly adjust the vibration intensity according to actual needs, improving the adaptability and durability of the system.

[0014] Preferably, the wind-driven fan blade includes a driving shaft and a plurality of blades. The driving shaft passes through the rotating frame and is rotatably connected to the rotating frame. The end of the driving shaft extending into the installation cavity is fixedly connected to the driving disc. Each of the plurality of blades has an assembly hole. After the driving shaft passes through the plurality of assembly holes, an assembly nut is threadedly connected to the end of the driving shaft, and the assembly nut abuts against the blade.

[0015] By adopting the above technical solution, the wind-driven fan blade can rotate with the airflow, and then drive the driving disc to rotate. During the rotation of the driving disc, the impact block is driven to reciprocate through the driving rod, thereby generating vibration, which helps the shedding of snow. At the same time, the convenient disassembly and assembly design of the blades enables the number of blades and the blade angles to be flexibly increased or decreased according to needs, improving the adaptability and practicability of the device.

[0016] Preferably, one side of the blade is provided with a positioning bump, and the other side is provided with a positioning hole. The adjacent blades are angle-locked by inserting the positioning bump into the positioning hole.

[0017] By adopting the above technical solution, the positioning bumps and positioning holes on the blades can achieve angle locking between adjacent blades, so as to maintain a stable blade angle under the action of wind force. This design not only facilitates the assembly and disassembly of the blades, but also ensures the relative stability between adjacent blades when adjusting the number and angle of the blades, improving the working efficiency and reliability of the wind-driven fan blade.

[0018] Preferably, a plurality of positioning holes on the blade are evenly distributed circumferentially with the assembly hole as the center.

[0019] By adopting the above technical solution, a plurality of positioning holes on the blade are evenly distributed circumferentially with the assembly hole as the center, so that when adjusting the number of blades and the angle between adjacent blades, the positioning bumps can be inserted into the positioning holes at corresponding positions, improving the stability of the angle between adjacent blades after the blades are increased or decreased. This not only helps to optimize the working performance of the wind-driven fan blade, but also ensures its stability and reliability under different wind speed conditions, so as to more effectively utilize the wind resources in the mountain area and promote the rapid shedding of snow.

[0020] Preferably, the mounting bracket includes an upper mounting plate and a lower mounting plate. Both the upper mounting plate and the lower mounting plate have mounting semi-holes, and the two mounting semi-holes enclose a mounting hole. The upper mounting plate and the lower mounting plate are detachably connected to each other.

[0021] By adopting the above technical solution, the mounting bracket includes an upper mounting plate and a lower mounting plate, both of which have mounting semi-holes, and the two mounting semi-holes enclose a mounting hole, making the connection between the mounting bracket and the mounting wire more convenient and fast. At the same time, the upper mounting plate and the lower mounting plate are detachably connected to each other, facilitating the quick replacement or repair of components when needed, and improving the maintainability and flexibility of the system.

[0022] Preferably, the drive disk and the drive rod are detachably connected to each other.

[0023] By adopting the above technical solution, the detachable connection between the drive disk and the drive rod enables the disconnection of the two during snow-free seasons, avoiding continuous ineffective impacts on the structure, reducing unnecessary wear and energy loss. At the same time, this design also allows for reconnection when needed to ensure that the vibration mechanism can be activated in a timely manner during snow seasons, effectively promoting snow shedding. In addition, the wind-driven fan blades can be optionally connected to the wind power generation module to make full use of the rich wind resources in mountainous areas for power generation, improving the overall utilization rate of the system.

[0024] Preferably, an adjustment disk is rotatably arranged on the column, and the column is provided with an adjustment driving member for rotating the adjustment disk. An installation buckle is arranged at the end of the installation wire, and an installation ring is arranged on the adjustment disk. The installation buckle is buckled on the installation ring.

[0025] By adopting the above technical solution, the adjustment disk rotatably arranged on the column and its adjustment driving member can achieve precise adjustment of the tension of the installation wire. During snow-free seasons, the installation wire can be tensioned through the adjustment disk to improve the overall stability and power generation efficiency of the photovoltaic panel; while during snow seasons, the installation wire can be appropriately relaxed to increase the tilt angle of the photovoltaic panel, which is beneficial for the natural sliding of snow and reduces the impact of snow on photovoltaic power generation. In addition, in the case of weak wind, the reciprocating rotation of the adjustment disk can be used to generate the up-and-down shaking of the installation wire to further assist in snow sliding and enhance the self-cleaning ability of the system.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. By suspending the photovoltaic panel on the installation wire with a certain bending deformation ability, when snow accumulates, the installation wire will undergo a downward bending deformation action. With the help of the unique wind resources in mountainous areas, the small swing of the installation wire helps to promote the shedding of snow on the inclined surface of the photovoltaic panel, reducing the power generation loss caused by snow.

[0027] 2. The bottom of the mounting frame is provided with a rotating frame and wind-driven fan blades. The abundant wind resources in the mountainous area are utilized to drive the wind-driven fan blades to rotate, thereby causing the driving disk to rotate and driving the impact block to slide reciprocally through the driving rod, generating vibrations to further promote the shedding of snow and improving the working efficiency of the photovoltaic panel.

[0028] 3. An adjusting disk and an adjusting driving member are provided on the column, and the tension degree of the mounting wire can be adjusted by adjusting the angle of the adjusting disk. In the snow-free season, the mounting wire can be tightened to keep the photovoltaic panel stable; in the snow season, the mounting wire can be appropriately relaxed to increase the inclination angle of the photovoltaic panel, which is beneficial to the faster sliding of snow.

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of the present invention, not all possible implementations. Those skilled in the art can fully combine the embodiments of the present invention to obtain other embodiments without creative labor, and these embodiments are also within the protection scope of the present invention.

[0032] The inventors of the present application found that as the core component of a solar power generation system, a photovoltaic panel directly converts solar energy into electrical energy through the photovoltaic effect and is widely used in fields such as rooftop power stations, ground power stations, and distributed energy systems. Its typical structure consists of multiple solar cell units encapsulated in a glass or polymer material protective layer and peripherally reinforced by a metal frame to ensure mechanical strength and environmental tolerance. In mountainous areas with cold or snowy conditions, the power generation efficiency of photovoltaic panels is significantly affected by environmental factors, and the power generation loss caused by snow cover is particularly prominent. Therefore, the present application mainly adopts the following flexible connection method to achieve the effect of promoting the active shedding of snow on the photovoltaic panel, thereby improving the power generation efficiency. The following is a further detailed description of the present application. Embodiment

[0033] Refer to Figure 1 , Figure 1The top view of the whole application is shown in the figure. The flexible connection method of photovoltaic panels in a mountain photovoltaic power station provided by the embodiment of the application includes a plurality of columns 1, which are pre-buried in the mountain soil by concrete pouring, and the distance between adjacent columns 1 is flexibly adjusted according to the actual situation. A pair of mounting wires 11 are arranged between adjacent columns 1. In the embodiment, the mounting wires 11 can be made of steel strands or other materials with high flexibility and strength, such as stainless steel wire ropes or high-strength nylon ropes. Selecting suitable materials can not only ensure the durability of the mounting wires 11, but also enhance the system's wind resistance and ability to adapt to various severe weather conditions. The two mounting wires 11 are parallel to each other, and the middle part can bend naturally under the action of its own gravity. A mounting frame 2 is connected between the two mounting wires 11, and the mounting frame 2 is used to install photovoltaic panels 12. Several mounting frames 2 and photovoltaic panels 12 are evenly distributed along the mounting wires 11. After installation, the two mounting wires 11 can erect several photovoltaic panels 12 in mid-air to reduce the impact of mountain trees on the photovoltaic panels 12 receiving light. The mountains have better wind resources. When the airflow blows against the mounting frame 2 or the photovoltaic panel 12, it will drive the mounting line 11 to shake as a whole. The mounting line 11 itself is flexible, so that the photovoltaic panel 12 does not always remain horizontal during the shaking process, but will be intermittently in a tilted state. Furthermore, this flexible installation method, combined with the wind resources in the mountains, can promote the shedding of snow on the surface of the photovoltaic panel 12. This design allows the photovoltaic panel 12 to bend and deform to a certain extent with the mounting line 11 in a suspended state. Especially when covered with snow, the mounting line 11 will bend downward due to gravity, which helps the snow to slide off through natural deformation or gravity, thereby improving the efficiency of photovoltaic power generation.

[0034] Reference Figure 1 , the side of the column 1 is rotatably provided with an adjusting disk 13, and the edge of the adjusting disk 13 is fixedly provided with a mounting ring 14. Correspondingly, the end of the mounting line 11 is provided with a mounting buckle 15. The mounting line 11 is actually installed with the column 1 by buckling the mounting buckle 15 on the mounting ring 14, so it is also convenient for later maintenance or replacement. The side wall of the column 1 is also fixedly provided with an adjusting drive 16. In this embodiment, the adjusting drive 16 is a motor for rotating the adjusting disk 13. The tension of the mounting line 11 can be adjusted by adjusting the angle of the adjusting disk 13 using the adjusting drive 16. For example, the mounting line 11 can be tightened in the season without snow accumulation, and the mounting line 11 can be appropriately relaxed in the season with snow accumulation, so that the photovoltaic panel 12 can be tilted to facilitate the sliding of snow accumulation. In addition, in the case of weak wind force, the reciprocating rotation of the adjusting disk 13 can also be used to realize the back and forth switching of the bending and straightening of the mounting line 11, so as to realize the up and down shaking of the mounting line 11, thereby assisting in promoting the sliding of snow accumulation.

[0035] Reference Figure 2, the mounting bracket 2 is integrally a plate-like structure, which includes an upper mounting plate 21 and a lower mounting plate 22. Both the upper mounting plate 21 and the lower mounting plate 22 have mounting semi-holes 23. After the upper mounting plate 21 and the lower mounting plate 22 are buckled, the two mounting semi-holes 23 enclose a mounting hole 24 for the mounting wire 11 to pass through and be fastened and positioned by bolts to realize the installation of the mounting bracket 2 and the mounting wire 11. In this application, the connection between the upper mounting plate 21 and the lower mounting plate 22 is designed to be detachable. The advantage of this design is to realize the convenient installation and maintenance of the mounting wire 11 in cooperation with the detachable method at the end of the mounting wire 11, and the position of the mounting bracket 2 can be quickly replaced or adjusted according to needs.

[0036] Refer to Figure 2 and Figure 3 , a rotating frame 3 is rotatably arranged at the bottom of the mounting bracket 2 through a bearing. An installation cavity 30 is arranged inside the rotating frame 3. The side of the installation cavity 30 has an opening, and a cover plate 31 for sealing the opening is detachably arranged on the outer wall of the rotating frame 3 through bolts. This design facilitates inspection and maintenance, and inspection and repair can be carried out without removing the entire device.

[0037] Refer to Figure 3 , a wind-driven fan blade 4 is rotatably connected to the bottom of the rotating frame 3. The wind-driven fan blade 4 includes a drive shaft 41 and a plurality of blades 42. The drive shaft 41 passes through the rotating frame 3 and is rotatably connected to the rotating frame 3 through a bearing. A drive disk 32 is arranged inside the installation cavity 30. The drive disk 32 is synchronously rotated with the wind-driven fan blade 4 by being fixedly connected to the drive shaft 41. An impact block 33 is also slidably connected to the middle of the installation cavity 30. A slide rod is fixedly arranged on the side of the impact block 33, and a chute is arranged on the side wall of the installation cavity 30. The slide rod extends into the chute to realize the stable sliding and stroke limitation of the impact block 33. The bottom of the impact block 33 is connected to a drive rod 34 through a buffer member 35. In this embodiment, the buffer member 35 is a spring, and the bottom of the drive rod 34 is rotatably arranged with the drive disk 32. This design utilizes the rich wind resources in mountainous areas. The drive disk 32 is driven to rotate by the wind-driven fan blade 4. During the rotation of the drive disk 32, the drive rod 34 will drive the buffer member 35 and the impact block 33 to slide reciprocally as a whole.

[0038] Refer to Figure 4, a force block 36 is provided at the top of the installation cavity 30, and a clearance is formed between the force block 36 and the installation cavity 30 so that the position of the force block 36 can be adjusted in the vertical direction along the installation cavity 30. An adjusting rod 37 is fixedly connected to the top of the force block 36, and the adjusting rod 37 passes through the top wall of the rotating frame 3 and is slidably connected to the rotating frame 3. The rotating frame 3 is provided with a locking member 38 for locking the force block 36. In this embodiment, the locking member 38 is a pair of locking nuts, both of which are threadedly connected to the adjusting rod 37, and are respectively located inside the installation cavity 30 and outside the rotating frame 3. After being tightened, the two locking nuts are respectively pressed against the inner side and the outer side of the top wall of the rotating frame 3 to achieve position locking of the adjusting rod 37. Mountain areas have relatively good wind resources. With the flow of air, the wind-driven fan blades 4 can be driven to rotate, and then the driving disk 32 can be driven to rotate. During the rotation of the driving disk 32, the driving rod 34 drives the impact block 33 to slide back and forth, so that the impact block 33 can continuously impact the rotating frame 3 through wind resources, and further promote the shedding of snow through vibration. And by adjusting the position of the force block 36, the position where the impact block 33 actually impacts during the reciprocating process can be actually adjusted, because the buffer 35 can automatically compensate for the adjustment stroke of the force block 36 to ensure that the impact block 33 can collide with the force block 36, thereby realizing the adjustment of the vibration degree, which is suitable for snow with different thicknesses.

[0039] Reference Figure 5 The assembly relationship between the driving shaft 41 of the wind-driven fan blade 4 and the plurality of blades 42 is as follows: the plurality of blades 42 all have assembly holes 420, the driving shaft 41 passes through the plurality of assembly holes 420 and then is threadedly connected with an assembly nut 43 at the end, and the plurality of blades 42 are pressed against each other by the assembly nut 43 and the outer wall of the rotating frame 3. In this way, the blades 42 can be conveniently disassembled and assembled, which is conducive to flexibly increasing or decreasing the number of blades 42 and adjusting the angle of the blades 42.

[0040] Reference Figure 6 and Figure 7 In addition, when the number of blades is more than three, among the blades 42, except for the blades 42 located on the outside, the blades 42 located in the middle are all provided with a positioning protrusion 44 on one side and a positioning hole 45 on the other side, and the blades 42 located on the outside are also provided with a positioning protrusion 44 or a positioning hole 45 accordingly. The positioning holes 45 on the blades 42 are evenly distributed along the circumference with the assembly hole 420 as the center, and the angles of adjacent blades 42 are locked by inserting the positioning protrusions 44 into the positioning holes 45. When actually adjusting the number of blades 42 and the angles of adjacent blades 42, the positioning protrusions 44 can be inserted into the positioning holes 45 at different positions to improve the stability of the angles of adjacent blades 42 after the increase or decrease of the blades 42. In addition, in the season without snow, the blades 42 can be folded and rotated upward to the side of the rotating frame 3 to reduce the impact of airflow on the shaking of the device.

[0041] The driving disk 32 and the driving rod 34 are detachably connected by means of buckles or the like. In seasons without snow, the connection state between the driving disk 32 and the driving rod 34 can be disconnected to avoid continuous ineffective impact of the structure. The wind-driven fan blade 4 can be selectively operated. For example, the wind-driven fan blade 4 can be connected to the wind power generation module to make full use of the wind resources in mountainous areas and jointly generate electricity with the photovoltaic panel 12.

[0042] In order to further improve the reliability and intelligence level of the system, in this embodiment, sensors and controllers can also be provided on the photovoltaic panel 12. The sensors are used to monitor the snow thickness on the photovoltaic panel 12 in real time, and the controllers are used to automatically start the adjusting driving member 16 when the sensors detect that the snow accumulation reaches a certain threshold, adjust the tension of the installation wire 11, make it retract and release periodically, increase the inclination angle and shaking degree of the photovoltaic panel 12, so as to accelerate the sliding speed of the snow.

[0043] The selection of sensors can be diversified. Commonly used ones include ultrasonic sensors, infrared sensors or pressure sensors, etc. These sensors can be connected to the controller through wireless communication technology to achieve real-time data transmission and remote monitoring.

[0044] In this embodiment, an anti-icing coating is also coated on the surface of the photovoltaic panel 12. This coating has good hydrophobicity and low friction coefficient, and can effectively reduce the probability of snow adhesion. Common anti-icing coating materials include fluorocarbon resin, polyurethane or silicone oil, etc. These materials not only have excellent waterproof performance, but also can extend the service life of the photovoltaic panel 12.

[0045] In addition to the anti-icing coating, a heating element is also provided on the back of the photovoltaic panel 12 in this embodiment. The heating element can be in the form of an electrothermal film, a resistance wire or a heating cable, etc., and is automatically turned on by the controller to increase the temperature of the photovoltaic panel 12 to cooperate in melting the snow on the surface area. The specific layout method of the heating element can be diverse, such as parallel laying, grid layout or spiral winding, etc., to ensure uniform heat distribution.

[0046] In order to avoid excessive energy consumption, the power of the heating element can be adjusted according to actual needs. For example, when the temperature is low, the heating time can be appropriately increased or the heating power can be increased; while in the case of high temperature, the heating time can be shortened and the heating power can be reduced to save energy.

[0047] The implementation principle of this embodiment is as follows: 1. Dynamic deformation and gravity collaborative snow removal mechanism The installation wire 11 is made of high-ductility steel strands (elongation at break ≥ 3%), and can produce a sag deformation of up to 15°-25° under snow load. For example, when the snow thickness on the surface of the photovoltaic panel 12 reaches 5 cm, the self-weight of the system increases by about 30 kg / m². At this time, the installation wire 11 forms a parabolic deformation within the critical yield strength range, causing the photovoltaic panel 12 to form an inclined angle gradient distribution. Experimental data shows that when the inclined angle of the panel surface exceeds 12°, the snow sliding speed can be significantly increased. Combined with the unique wind speed in mountainous areas, the snow on the surface can fall off relatively quickly. Different from traditional rigid brackets, the unique flexible deformation ability of this structure enables the snow to continuously slide under the action of gravity instead of breaking and falling off locally.

[0048] 2. Wind-energy-mechanical energy composite drive system The chord length of the blade 42 of the wind-driven fan blade 4 can be adjusted according to the actual situation. For example, it is required to generate a torque of 12-15 N·m at a wind speed of 8 m / s. The drive disk 32 can adopt an asymmetric cam structure to facilitate increasing the vibration degree during impact. When the perennial snow thickness in the actual area is relatively high, the impact block 33 can be appropriately lowered by adjusting the lock nut to increase the impact energy of each impact. With a stable impact frequency, an equivalent and better snow removal effect can be produced. The buffer spring can effectively reduce the impact of the peak impact force on the drive rod 34 and avoid structural damage.

[0049] 3. Intelligent adjustment system The sensor for measuring the snow thickness can select a pressure sensor and adopt a MEMS piezoresistive array (resolution ±10 Pa), which is arranged in a 20×20 cm grid to monitor the snow distribution in real time. When the local pressure difference exceeds the set threshold (corresponding to 5 cm of snow), the controller starts a hierarchical response: the first-level response (snow thickness of 5-10 cm) triggers the motor to rotate forward and backward periodically at a speed of 0.5 rpm, causing the installation wire 11 to produce an angular fluctuation of ±5°; the second-level response (snow thickness ≥ 10 cm) activates the heating element (power density 300 W / m²) to work, and at the same time adjusts the stroke of the impact block 33 to the maximum.

[0050] 4. Multi-modal working strategy Normal mode (temperature ≥ 5℃): The tension of the installation wire 11 is maintained at 120 kN, the impact mechanism is on standby, and the wind-driven fan blade 4 can be used for wind power generation.

[0051] Winter standby mode (-20℃ ≤ T < 5℃): The tension of the installation wire 11 is reduced to 80 kN, and preheating is used to maintain the panel surface temperature above -5℃.

[0052] Snow removal mode (snow thickness ≥ 5 cm): Start the shaking of the installation wire 11 + mechanical impact of the impact block 33 + surface heating for composite snow removal.

[0053] Hurricane mode (wind speed ≥ 15 m / s): Automatically tighten the installation line 11 to 150 kN to reduce damage to the photovoltaic panel 12 caused by excessive swaying of the installation line 11.

[0054] The above are all preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
