Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and in particular to an adaptive photovoltaic panel support and photovoltaic system for desert regions. Background Technology

[0002] With the increasing global demand for renewable energy, photovoltaic (PV) power generation technology has been widely applied globally, especially in desert and Gobi regions rich in solar resources. Desert regions possess abundant solar resources, vast land areas, and low development costs, making them ideal locations for PV equipment installation. Vigorously developing the desert PV industry is of great significance for promoting the clean energy transition. However, the unique characteristics of the desert environment bring many challenges to the stable operation of PV equipment, mainly manifested in:

[0003] I. Desert environments are characterized by frequent sandstorms and highly mobile sand dunes. A key technical challenge lies in the fact that the continuous deposition and migration of sand particles can easily bury photovoltaic modules and their supporting structures. When sand accumulates around and under the photovoltaic array, it may obstruct the photovoltaic modules, leading to a significant decrease in their power generation efficiency. If not cleaned up in time, the entire photovoltaic array and even its support structure will eventually be completely buried, resulting not only in power generation loss but also in deformation, twisting, or even complete collapse of the support structure due to enormous static pressure, causing huge economic losses and maintenance difficulties.

[0004] Second, strong winds are frequent at night in desert areas. Most existing photovoltaic panel supports are fixed structures, which cannot adjust the posture of the photovoltaic panels according to changes in the day and night environment. If the photovoltaic panel supports maintain a fixed tilt angle, they are prone to bearing huge wind loads due to their large windward area, which can lead to deformation of the supports and damage to the photovoltaic panels.

[0005] Third, in desert areas, sand and dust settle quickly during the day, and sand and dust easily accumulate on the surface of photovoltaic panels, blocking sunlight and causing a significant decrease in power generation efficiency.

[0006] Fourth, some of the support structures with cleaning functions require manual triggering and cannot be linked with the wind resistance requirements at night; moreover, the support instruments lack a sand and dust cleaning mechanism, which makes them susceptible to the effects of accumulated sand and dust, leading to detection failure.

[0007] In summary, existing traditional photovoltaic (PV) brackets are insufficient in wind and dust resistance, making it difficult to meet the core requirements of "wind-resistant and stable, low dust accumulation, and easy operation and maintenance" for PV equipment in desert areas, thus restricting the large-scale development of the desert PV industry.

[0008] In view of this, the present invention is hereby proposed. Summary of the Invention

[0009] The purpose of this invention is to solve the problem that existing photovoltaic panel supports are not strong enough in terms of wind and dust resistance, are easily affected by sand and dust accumulation, and are difficult to meet the usage requirements of special environments in desert areas.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] This invention first provides an adaptive photovoltaic panel support for desert areas, used to support photovoltaic panels, comprising:

[0012] The base includes a box-shaped base and multiple adaptive spiral blades installed at the bottom of the box-shaped base. The box-shaped base is disposed on the surface of the desert stratum, and the multiple adaptive spiral blades are buried in the desert stratum to support the box-shaped base and can adaptively lift the box-shaped base under a first predetermined condition.

[0013] An adjustable support assembly is fixed to the base to rotatably support the back of the photovoltaic panel and is capable of adjusting the tilt angle of the photovoltaic panel under a second predetermined condition.

[0014] A cleaning assembly includes a linkage unit and a cleaning unit, wherein the linkage unit is installed on the back of the photovoltaic panel and can be linked with the adjustment support assembly under a second predetermined condition to activate the cleaning unit, and the cleaning unit is installed on the photovoltaic panel for cleaning the surface of the photovoltaic panel.

[0015] In an optional embodiment, the box-type base is equipped with an adaptive lifting unit, including:

[0016] The first motor and the central gear are both built into the center of the box-type base, and the first motor is driven by the central gear.

[0017] Multiple planetary gears are evenly distributed circumferentially around the central gear and mesh with it. Each planetary gear is correspondingly connected to multiple adaptive helical blades for drive connection.

[0018] An infrared sensor is installed on the top of the box-type base and at a certain height above the upper surface of the box-type base. It is used to detect whether the box-type base is covered by sand and dust and the thickness of the sand and dust accumulation.

[0019] In an optional embodiment, the adjustable support assembly includes:

[0020] A rotating part, which is fixed to the back of the photovoltaic panel;

[0021] The two columns are fixed at one end to the box-type base and rotatably support the rotating part at the other end.

[0022] The second motor is fixed to at least one of the columns and is drivenly connected to the rotating part.

[0023] In an optional embodiment, the linkage unit includes:

[0024] A sealed box is fixed to the back of the photovoltaic panel, and the inner cavity of the sealed box is in air communication with the cleaning unit;

[0025] The first piston plate is embedded in the inner cavity of the sealed box and corresponds to the adjustment support assembly via an extended push rod on the side away from the photovoltaic panel. It can be pushed by the adjustment support assembly under a second predetermined condition to start the cleaning unit.

[0026] An elastic reset member is disposed in the inner cavity of the sealed box near the photovoltaic panel and abuts against the first piston plate to reset after the first piston plate is pushed to its maximum stroke.

[0027] In an optional embodiment, the adjusting support assembly includes an abutment portion fixed to the upper ends of the two columns and extending horizontally or at a certain angle to abut and push the push rod under a second predetermined condition.

[0028] In an optional embodiment, the cleaning unit includes:

[0029] The second piston plate is embedded in the inner cavity of the photovoltaic panel, dividing the inner cavity into two regions;

[0030] The first air pipe is located at the bottom of the photovoltaic panel and one end is connected to the inner cavity of the sealed box, while the other end is connected to the lower area of ​​the inner cavity of the photovoltaic panel.

[0031] The second air pipe is located in the upper part of the inner cavity of the photovoltaic panel, with one end connected to the second piston plate and the other end extending out of the inner cavity of the photovoltaic panel and connected to an air blowing module. An air inlet is provided on the second air pipe.

[0032] An air blowing module is slidably mounted on the photovoltaic panel and connected to the second air pipe.

[0033] In an optional embodiment, the cleaning unit further includes:

[0034] The first pulley and the second pulley are respectively fixed to the upper edge and the lower edge of the photovoltaic panel;

[0035] A pull rope is wound around the first pulley and the second pulley, with one end connected to the second piston plate and the other end connected to the air blowing module.

[0036] In one alternative embodiment, the second air tube is a flexible tube; the air inlet is located at one end of the second air tube near the second piston plate.

[0037] In an alternative embodiment, a protective component is further included, the protective component comprising:

[0038] A folding curtain, one side of which is installed on the photovoltaic panel and the other side is fixed to the top of the air blowing module. The folding curtain can be unfolded and folded up as the air blowing module slides along the surface of the photovoltaic panel to provide protection.

[0039] The present invention also provides an adaptive photovoltaic system for desert regions, comprising:

[0040] The aforementioned adaptive photovoltaic panel bracket; and

[0041] A photovoltaic panel, wherein the photovoltaic panel is mounted and supported by the adaptive photovoltaic panel bracket.

[0042] Beneficial Effects: This invention provides an adaptive photovoltaic panel support system for desert regions. Compared with existing technologies, it can automatically adjust the photovoltaic structure's state according to real-time changes in the desert environment, thereby preventing burial, reducing wind resistance, clearing sand and dust, improving power generation efficiency, and reducing the failure rate. Specifically, this can be better understood from one or more of the following aspects:

[0043] Firstly, the adaptive photovoltaic panel support can detect whether the photovoltaic structure is covered by sand and dust through infrared sensors. When the amount of sand and dust accumulation reaches a preset value, it automatically raises the height of the photovoltaic structure to keep it away from the sand and dust accumulation layer, thus avoiding the burial of photovoltaic modules and their supporting structure due to sand deposition and dune migration.

[0044] Secondly, the adaptive photovoltaic panel bracket can automatically adjust the photovoltaic structure to a flat state when necessary, effectively resisting the impact of strong winds in the desert at night. During the turning process, the air blowing module of the cleaning component blows and cleans the photovoltaic structure. At the same time, the pull rope drives the air blowing module to move on the surface of the photovoltaic structure for comprehensive cleaning.

[0045] Thirdly, this adaptive photovoltaic panel support, through the linkage of the protection and cleaning components, can automatically unfold the folding curtain while completing the cleaning process, which can protect the photovoltaic panels, prevent secondary accumulation after cleaning, and ensure the stable operation of the photovoltaic structure.

[0046] Fourthly, the adaptive photovoltaic panel support system allows each component to be used in conjunction with existing conventional photovoltaic panels, or to be modified structurally, making it highly adaptable.

Other features of the invention will become readily apparent from the following description. Furthermore, implementation of any embodiment of the present invention does not imply the simultaneous possession or achievement of multiple or all of the aforementioned beneficial effects.

Here, the illustrative embodiments and descriptions of the present invention are used to explain the present invention, but are not intended to limit the present invention.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0073] The implementation of the present invention will be described in detail below with reference to preferred embodiments.

[0074] Overall reference Figure 1 , Figure 2As shown in the figure, an adaptive photovoltaic panel support for desert areas is proposed in this embodiment of the invention. This support is used to support photovoltaic panels 50 and includes a base 10, an adjusting support component 20, and a cleaning component 30. It is easy to understand that the base 10 is buried in the desert stratum, serving as the foundation structure of the entire support, and extends to a certain depth to provide stable support. The adjusting support component 20 is mounted on the base 10 to support the upper structure, especially the photovoltaic panels 50. The cleaning component 30 is used to automatically clean the sand and dust accumulation on the surface of the photovoltaic panels 50 under specific conditions or at specific times, ensuring the photovoltaic panels 50's ability to receive sunlight and guaranteeing power generation efficiency.

[0075] Specifically, such as Figure 3 The base 10 includes a box-type base 11 and multiple adaptive spiral blades 12 installed at the bottom of the box-type base 11. The box-type base 11 is set on the surface of the desert stratum, and the multiple adaptive spiral blades 12 are buried in the desert stratum to support the box-type base 11.

[0076] The box-type base 11 has a hollow box structure, and related components are installed inside, which will be described in detail later. In this embodiment of the invention, the box-type base 11 can be formed by the interlocking of upper and lower shell halves, which are similar to flange structures. Preferably, the upper and lower shell halves are circular, and are fixed with bolts at the interlocking edges. This structure is simple, easy to assemble on site, and the use of metal for the upper and lower shell halves provides greater weight, ensuring the stability of the base 10.

[0077] Four adaptive spiral blades 12 are fixed to the bottom of the box-type base 11 and drilled into the desert strata to a sufficient depth (the number and length in the figure are only for illustration; the actual design should be flexible based on load-bearing capacity and stability). They are capable of adaptively lifting the box-type base 11 under a first predetermined condition. It should be noted that the first predetermined condition is that when sand and dust accumulate to a certain thickness, the four adaptive spiral blades 12 are activated to lift the upper structure to prevent it from being buried by the sand and dust, and a cleaning mechanism is simultaneously initiated.

[0078] In a preferred embodiment, in order to enable the four adaptive spiral blades 12 to adaptively lift under a first predetermined condition, this embodiment has an adaptive lifting unit installed on the box-type base 11, including: a first motor 111 and a central gear 112, a plurality of planetary gears 113, and an infrared sensor 114.

[0079] The first motor 111 and the central gear 112 are both built into the center of the box-type base 11, and the first motor 111 is driven by the central gear 112; for example Figure 4As shown, a cylindrical groove is recessed downwards in the center of the box-type base 11, in which the first motor 111 is embedded. The bottom of the cylindrical groove is designed to be conical to facilitate the stable placement of the entire base 10 on the desert strata. The central gear 112 is located above the first motor 111 and is connected to the output shaft of the first motor 111. When the first motor 111 starts, it drives the central gear 112 to rotate.

[0080] like Figure 5 As shown, four planetary gears 113 are evenly arranged in a circumferential direction around the central gear 112 and mesh with the central gear 112. The four planetary gears 113 have a rotating shaft at their center. The rotating shaft passes through the bottom shell of the box-type base 11 and is connected to the adaptive helical blade 12 below. When the four planetary gears 113 rotate, they drive one adaptive helical blade 12 to rotate. The forward rotation is used to drill into the desert strata, and the reverse rotation is used to lift upward.

[0081] In this invention, an infrared sensor 114 is installed on top of the box-type base 11, extending a certain height above the upper surface of the base 11, to detect whether the base 11 is covered by sand and dust and the thickness of the sand accumulation. The infrared sensor 114 can be screwed into a threaded hole at the center of the upper surface of the base 11, or it can be installed on a separate bracket. During use, the infrared sensor 114 monitors the sand accumulation at the base 10 in real time. When the sand accumulation reaches a certain height or even buries the sensor, the first motor 111 is activated to drive the adaptive spiral blades 12 to rotate in the opposite direction to lift the device, ensuring that the device remains above the sand dune. This prevents the photovoltaic modules and their supporting structure from being buried due to sand deposition and dune migration.

[0082] See also Figure 6 , Figure 7 The adjustment support component 20 of the present invention is fixed to the base 10 and rotatably supports the back of the photovoltaic panel 50, and can adjust the tilt angle of the photovoltaic panel 50 under a second predetermined condition. The second predetermined condition may be, for example, a situation with no sunlight at night, or a strong wind. In this case, the photovoltaic panel 50 is adjusted to a horizontal state to reduce the windward area, resist the attack of large sandstorms, and prevent the support from deforming and the photovoltaic panel from breaking.

[0083] In a preferred embodiment, the adjustment support assembly 20 includes a rotating part 22, a column 21, and a second motor 23.

[0084] The rotating part 22 is a fixed part, which is fixed to the back of the photovoltaic panel 50; specifically, it adopts a strip box or strip block structure, mainly used to pass through the rotating shaft.

[0085] Two columns 21 are fixed at one end to the box-type base 11, and the other end rotatably supports the rotating part 22. Specifically, the top ends of the two columns 21 are pre-set with mounting holes, and a rotating shaft passes through the rotating part 22 and is rotatably supported in the corresponding mounting holes at both ends (bearings can be added). The rotating shaft is fixed to the rotating part 22 as a whole. When it rotates, it drives the rotating part 22 and further drives the photovoltaic panel 50 to rotate to adjust the tilt angle.

[0086] A second motor 23 is fixed to one of the columns 21, and its output shaft is driven by the rotating shaft of the rotating part 22. When the second motor 23 starts, it drives the rotating shaft and the rotating part 22 to rotate.

[0087] See also Figure 7 , Figure 8 , Figure 9 The cleaning component 30 provided by the present invention includes a linkage unit 31 and a cleaning unit 32. The linkage unit 31 is installed on the back of the photovoltaic panel 50 and can be linked with the adjustment support component 20 under a second predetermined condition to start the cleaning unit 32. The cleaning unit 32 is installed on the photovoltaic panel 50 for cleaning the surface of the photovoltaic panel 50.

[0088] In a preferred embodiment, the linkage unit 31 includes: a sealing box 311, a first piston plate 312, and an elastic reset member 314.

[0089] The sealed box 311 is fixed to the back of the photovoltaic panel 50, specifically above the rotating part 22. The inner cavity of the sealed box 311 forms a sealed internal space and is in air communication with the cleaning unit 32. Figure 9 As shown, the sealed box 311 adopts a strip-shaped structure, and its cross-sectional dimensions should ensure that the internal gas is completely discharged, which is sufficient to clean or substantially clean the sand and dust accumulation on the surface of the photovoltaic panel 50.

[0090] Inside the sealed box 311, a first piston plate 312 is provided. The shape of the first piston plate 312 matches the shape of the sealed box 311 and divides the internal space of the sealed box 311. The first piston plate 312 is embedded in the inner cavity of the sealed box 311 and corresponds to the adjustment support assembly 20 through the extended push rod 313 on the side away from the photovoltaic panel 50. It can be pushed by the adjustment support assembly 20 under a second predetermined condition to start the cleaning unit 32. The figure shows that a push rod 313 extends from both ends of the sealed box 311. The push rod 313 can be further provided with a cross plate to facilitate contact with the adjustment support assembly 20.

[0091] Inside the sealed housing 311, near the photovoltaic panel 50, a built-in elastic reset member 314 is installed. The elastic reset member 314 abuts against the first piston plate 312 to reset after the first piston plate 312 is pushed to its maximum stroke. In this embodiment, the elastic reset member 314 is one or more helical springs.

[0092] In a preferred embodiment, such as Figure 6 , Figure 7 As shown, to facilitate contact with the push rod 313 on the sealing box 311, an abutment portion 24 is further provided on the adjusting support assembly 20. The abutment portion 24 is fixed to the upper end of the two columns 21 and extends horizontally or at a certain inclined angle to abut and push the push rod 313 under a second predetermined condition. In this embodiment, the abutment portion 24 is specifically a semi-circular plate that extends horizontally or at a certain inclined angle, so that it can abut the push rod 313 precisely when the photovoltaic panel 50 rotates to the horizontal angle.

[0093] See also Figure 8 , Figure 9 , Figure 10 In a preferred embodiment, the cleaning unit 32 provided by the present invention includes: a second piston plate 321, a first air pipe 322, a second air pipe 323, and an air blowing module 325.

[0094] In this invention, a second piston plate 321 is provided in the inner cavity of the photovoltaic panel 50, which divides the inner cavity into two regions. It should be noted that the cleaning unit 32 can be integrated with the original photovoltaic panel structure, or it can be adjusted based on the original photovoltaic panel. For example, a shell can be provided at the bottom of the original photovoltaic panel, and the components of the cleaning unit 32 can be arranged in the shell.

[0095] The first air pipe 322 is located at the bottom of the photovoltaic panel 50 (or its housing), with one end connected to the inner cavity of the sealed box 311 and the other end connected to the lower region of the inner cavity of the photovoltaic panel 50; in a specific arrangement, the first air pipe 322 can pass through the rotating part 22, such as... Figure 9 As shown. With the help of the first air pipe 322, the gas discharged from the first piston plate 312 in the inner cavity of the sealed box 311 is rapidly compressed to the lower region of the inner cavity of the photovoltaic panel 50, thereby pushing the second piston plate 321 to move.

[0096] Furthermore, the present invention provides a second air pipe 323 in the upper region of the inner cavity of the photovoltaic panel 50. Preferably, two or more second air pipes 323 are provided, with one on each side of the photovoltaic panel in this embodiment. The lower end of the second air pipe 323 is connected and fixed to the second piston plate 321, and the upper end extends out of the inner cavity of the photovoltaic panel 50 and connects to the air blowing module 325. An air inlet 324 is provided on the second air pipe 323. The gas compressed into the lower region of the inner cavity of the photovoltaic panel 50 pushes the second piston plate 321 to move. During this process, the gas in the upper region of the inner cavity of the photovoltaic panel 50 is compressed from the air inlet 324 to the second air pipe 323, thereby delivering a rapid airflow to the air blowing module 325 to clean the surface of the photovoltaic panel 50.

[0097] The air blowing module 325 is slidably mounted on the photovoltaic panel 50 and is connected to the second air pipe 323. Figure 8 The diagram shows that multiple air blowing nozzles are evenly arranged on the air blowing module 325. The module is hollow and connected to the second air pipe 323 so that the gas compressed by the second air pipe 323 is synchronously ejected from the multiple air blowing nozzles. The module moves as a whole and drives the multiple air blowing nozzles to move synchronously.

[0098] In a preferred embodiment, the cleaning unit 32 further includes: a first pulley 326 and a second pulley 327, and a pull rope 328.

[0099] The first pulley 326 and the second pulley 327 are fixed to the upper and lower edges of the photovoltaic panel 50, respectively. Specifically, four pulleys are installed at the four corners of the upper and lower edges of the photovoltaic panel 50. The upper and lower pulleys on both sides of the photovoltaic panel 50 form a group. A pull rope 328 is wound around the first pulley 326 and the second pulley 327, with its lower end passing through the inner cavity of the photovoltaic panel 50 and connected to the second piston plate 321. The other end is connected to the air blowing module 325. The pull rope 328 on the other side adopts the same arrangement as the first pulley 326 and the second pulley 327. When the gas pressed into the lower area of ​​the inner cavity of the photovoltaic panel 50 pushes the second piston plate 321 to move, the second piston plate 321 drives the pull rope 328 to move synchronously. The pull rope 328 passes around the first pulley 326 and the second pulley 327, driving the air blowing module 325 to move back and forth on the surface of the photovoltaic panel 50 for air blowing cleaning.

[0100] Preferably, the second air tube 323 is a flexible tube; the flexible tube allows it to move around the second pulley 327 as the air blowing module 325 moves. The flexible tube should have sufficient strength to prevent it from being stretched and broken.

[0101] Preferably, the air inlet 324 on the second air pipe 323 is located at one end of the second air pipe 323 near the second piston plate 321, such as... Figure 10 As shown, this is to compress as much gas as possible from the upper region of the inner cavity of the photovoltaic panel 50 into the pipe.

[0102] See also Figure 1 , Figure 7As shown, in a preferred embodiment of the present invention, a protective component 40 is further provided. The protective component 40 mainly includes a folding curtain 41, which is horizontally arranged on the photovoltaic panel 50. Specifically, one side is installed on the photovoltaic panel 50 (the last set of folding units), and the other side (the first set of folding units) is fixed to the top of the air blowing module 325 and can unfold and fold up as the air blowing module 325 slides along the surface of the photovoltaic panel 50. Of course, the present invention can further provide slide rails 42 on both sides of the photovoltaic panel 50 (shell), and the two ends of the folding curtain 41 are slidably engaged in the slide rails 42 so that it can be opened or closed as it moves. It is easy to understand that the significance of adding the folding curtain 41 is that when the photovoltaic panel 50 is adjusted to a horizontal state at night, the air blowing module 325 thoroughly cleans the surface of the photovoltaic panel 50, and at the same time drives the folding curtain 41 to automatically unfold, thereby playing a protective role and preventing the accumulation of sand and dust on the surface of the photovoltaic panel 50 at night from causing pollution and damage. During the day when the photovoltaic power generation is in progress, the second motor 23 drives the photovoltaic panel 50 to tilt, and after the accumulated sand and dust slides off the folding curtain 41, the folding curtain 41 can be controlled to fold and retract.

[0103] Based on the adaptive photovoltaic panel bracket, the present invention further provides an adaptive photovoltaic system for desert areas, in which the photovoltaic panel 50 is installed and supported by the adaptive photovoltaic panel bracket, thereby improving the power generation efficiency and service life of the photovoltaic panel in desert areas.

[0104] It should be noted that the first motor 111 and the second motor 23 mentioned above can both be powered by photovoltaic power generation, without the need for external power. The detection and signal control of the infrared sensor 114 can be completed by the control center or by a single-chip microcomputer deployed on site. Wind detection and nighttime light detection can be carried out by conventional means, which are existing technologies and will not be described in detail in this invention.

[0105] Working principle:

[0106] When the photovoltaic structure is in use, the infrared sensor 114 detects the presence of sand and dust, and then controls the first motor 111 to drive the central gear 112 to rotate. With the help of the planetary gear 113, the adaptive spiral blades 12 move upward and lift the device, thereby raising the overall height of the device. This ensures that the device can always remain on the sand dune, preventing the photovoltaic modules and their supporting structure from being buried due to sand deposition and dune migration.

[0107] During nighttime or periods of heavy sandstorms, the second motor 23 drives the photovoltaic panel 50 to turn horizontally. During this turning process, the contact part 24 pushes the push rod 313, causing the first piston plate 312 to pressurize the gas inside the sealed box 311 into the inner cavity of the photovoltaic panel 50. The pressurized gas further pushes the second piston plate 321 to move, pulling the pull rope 328. The pull rope 328 drives the air blowing module 325 downwards. Simultaneously, the second piston plate 321 discharges the gas from the inner cavity of the photovoltaic panel 50 through the second air pipe 323 and the air blowing module 325, allowing several air nozzles on the air blowing module 325 to clean the surface of the photovoltaic panel 50. Furthermore, the movement of the air blowing module 325 directly unfolds the folding curtain 41. Figure 11 As shown, the air blowing module 325 has moved to the bottom of the photovoltaic panel 50, completing the comprehensive cleaning of the photovoltaic panel 50. At the same time, both ends of the folding curtain 41 slide synchronously to the bottom in the slide rail 42, thereby shielding and protecting the photovoltaic panel 50.

[0108] When no protection is needed, the second motor 23 drives the photovoltaic panel 50 to reset, the abutment part 24 moves away from the push rod 313, the elastic reset member 314 pushes the first piston plate 312 to reset, so that the air blowing module 325 resets upward, and at the same time the folding curtain 41 folds up, so that the photovoltaic structure can be put back into use.

[0109] Through simple mechanical linkage and collaborative operation between components, without the need for excessive electrical control equipment, and using only air blowing for cleaning, the photovoltaic structure can automatically adjust its own state according to the real-time changes in the desert environment. This achieves a high degree of integration of multiple functions such as preventing burial, reducing wind resistance, cleaning up sand and dust, and protecting the structure, thereby improving power generation efficiency, reducing failure rate, reducing maintenance and repair costs, and providing comprehensive protection for the safe and stable operation of the photovoltaic system in extreme environments.

[0110] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
