Description

Technical Field

[0001] This invention relates to the field of solar power generation device technology, specifically to a solar power generation device. Background Technology

[0002] With the surge in global demand for clean energy, solar power generation devices have become core application equipment in the new energy field due to their advantages of renewable resources and zero pollution operation. However, existing solar power generation devices have the following problems in actual operation, limited by clean energy mechanisms, tracking accuracy, and structural design:

[0003] The core performance indicator of solar power generation devices is power generation efficiency, while the surface cleanliness of solar power generation modules directly determines light transmittance. According to industry data, when dust, oil, and other pollutants adhere to the surface of the modules, the light transmittance can decrease by 15%-35%, corresponding to a simultaneous decline in power generation efficiency. Furthermore, long-term accumulation of stubborn pollutants can also trigger hot spot effects, accelerating module aging.

[0004] However, existing technologies always use fixed amplitude cleaning when cleaning solar panels, and the aforementioned cleaning structure is prone to damaging the solar panels. At the same time, existing rigid photovoltaic panels are easily scratched by sand and dust, and flexible power generation films are easily damaged by hail.

[0005] Based on this, the present invention provides a solar power generation device to solve the problems mentioned in the background art. Summary of the Invention

[0012] As a preferred technical solution of the present invention, an electric rotator is installed on the dual-axis shifting frame, a rotating frame is installed on the rotation output end of the electric rotator, the rotating frame is hinged to the pitch frame, and an angle adjustment push rod is hinged between the pitch frame and the rotating frame.

[0013] As a preferred embodiment of the present invention, the control unit includes a battery box mounted on a fixed frame, the battery box containing a storage battery, a microcontroller mounted on the end face of the battery box, a light angle sensor, a dust sensor, and a temperature sensor mounted on the pitch frame, the data output terminals of the light angle sensor, the dust sensor, and the temperature sensor being electrically connected to the data receiving terminal of the microcontroller, the power supply output terminal of the storage battery being electrically connected to the power input terminal of the microcontroller, and the power supply output terminals of the solar power generation film being electrically connected to the storage battery.

[0014] As a preferred technical solution of the present invention, the scissor-type telescopic mechanism includes a set of scissor frame units that are hinged in sequence. The display frame and the tilting frame are slidably connected to a movable hinge seat and are fixedly installed on each other. The movable hinge seat and the fixed hinge seat are both hinged to the scissor frame units at adjacent positions.

[0015] As a preferred technical solution of the present invention, the transmission module includes a drive motor mounted on the pitch frame and a drive screw rotatably connected to the pitch frame. The drive screw is threadedly connected to the movable hinge seat on the pitch frame, and the output shaft end of the drive motor is connected to the drive screw via a third toothed belt.

[0016] As a preferred technical solution of the present invention, the baseband is made of nylon cut-resistant fabric, the length of the baseband is 7 times the maximum extension length of a single scissor telescopic mechanism, and the length of the solar power generation film is 1.5 times the maximum extension length of a single scissor telescopic mechanism.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] To address the problems of inadequate cleaning of solar power generation devices using fixed-amplitude vibration, blind spots in fixed brush structures, high manual cleaning costs, and the risk of scratching the power panels, this invention utilizes a deep, synergistic cleaning system combining bidirectional variable-amplitude vibration, spiral brush washing, and cleaning fluid spraying, along with dynamic electronic control, to create a comprehensive, blind-spot-free cleaning solution for solar power generation devices. The first rotating wheel of the bidirectional vibration platform has three first sector tooth segments with center angles of 30°, 40°, and 50°, which can alternately drive the single-axis moving frame to generate small, medium, and large gradient amplitudes. The small amplitude driven by the 30° sector tooth segment gently shakes off loose and thin dust, preventing dust spread; the medium amplitude of the 40° sector tooth segment shakes off tightly adhered mid-layer dust without excessive force; and the large amplitude of the 50° sector tooth segment precisely impacts stubborn stains, increasing the removal rate of stubborn dust.

[0019] The variable amplitude vibration of this invention is linked with the cleaning fluid spraying system of the storage tank, booster pump, and brush shaft. When the dust sensor detects excessive dust, the microcontroller starts the booster pump, and the cleaning fluid enters the fluid channel of the brush shaft through the three-way hose. It is then evenly sprayed onto the surface of the solar power film from regularly distributed cleaning nozzles. Combined with the axial cleaning force of the spiral brush blades, it can clean the dust on the solar power film and avoid dry brushing friction damage to the coating. In addition, the servo motor supports high and low speed dual modes. In the cleaning mode, the high speed increases the vibration frequency and enhances the cleaning effect. In the normal power generation mode, the low speed works periodically to avoid the solar power film being in a high-frequency vibration state for a long time, which significantly reduces the risk of damage to the solar power film during the cleaning process. This synergistic design of gradient vibration, spraying, brushing, and intelligent speed regulation breaks through the limitations of the one-way trade-off of existing cleaning technologies and achieves the triple goals of thorough cleaning, adequate protection, and controllable energy consumption.

[0020] 3. Addressing the issues of existing rigid photovoltaic panels being easily scratched by sand and dust, and flexible photovoltaic films being easily damaged by hail, this invention utilizes a synergistic structure of roller winding and cut-resistant fabric baseband protection, combined with the environmental response capability of the control unit, to form an active protection closed loop under severe weather conditions. When temperature and dust sensors detect severe weather such as hail or sandstorms, the microcontroller automatically triggers the drive motor to reverse, and the two rollers rotate in the opposite direction through the first toothed belt, completely winding the solar photovoltaic film onto the rollers. At this time, the non-photovoltaic film installation area of ​​the baseband is naturally exposed, and the high strength of the cut-resistant fabric can resist hail impact and sand and dust scratches, preventing the photovoltaic film from directly contacting external impacts. Compared with the passive bearing method in existing technologies, this provides a significant improvement. The design of this invention offers two core advantages in its protective mechanism: first, it actively retracts rather than passively protects, physically isolating the power-generating membrane from the harsh environment through rollers, thus increasing the success rate of protection; second, it utilizes a baseband for collaborative protection, with the baseband length being seven times the maximum extension length of a single scissor-type telescopic mechanism, allowing it to completely wrap around the power-generating membrane during retraction, avoiding damage from wrinkles during winding. Furthermore, the nylon cut-resistant fabric has a longer service life than ordinary fabric basebands. In addition, this protective action is linked to the retraction function of the scissor-type telescopic mechanism, with the transmission module driving the scissor frame unit to retract, bringing the display stand closer to the tilting frame, further reducing the device's size and decreasing the wind-exposed area in severe weather, thus forming a dual protection of retraction and contraction.

[0021] 4. Addressing the issues of inconvenient transportation, easy jamming of simple telescopic structures, and poor stability in existing solar power generation devices, this invention achieves a dual improvement in both flexible adjustment of the light-receiving area and operational stability through the coordinated design of a scissor-type telescopic mechanism, a transmission module, and optimized baseband length. The scissor-type telescopic mechanism consists of a set of sequentially hinged scissor frame units. Both the deployment frame and the tilting frame are equipped with slidingly connected movable hinge seats and fixed fixed hinge seats. The drive motor of the transmission module drives the drive screw to rotate via a third toothed belt, driving the movable hinge seat to slide, thereby controlling the smooth deployment or retraction of the scissor frame units. This structure offers improved stability compared to existing telescopic structures with pull rods, preventing wrinkles in the solar power generation film caused by swaying of the display stand. Furthermore, the baseband length is designed to be 7 times the maximum extension length of a single scissor-type telescopic mechanism, and the solar power generation film length is 1.5 times that. When unfolded, the baseband can completely cover the display stand and tilting frame area, ensuring the solar power generation film is fully extended without the risk of tensile breakage. When retracted, the baseband can be completely wound up by rollers, preventing wrinkles and overlaps in the solar power generation film. This design allows the device to adjust its light-receiving area according to the size of the site and shrink to its minimum volume during transport, effectively improving the deployment flexibility of this power generation device.

[0034] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0035] The present invention provides the following preferred embodiments.

[0036] like Figure 1 , Figure 2 and Figure 5 As shown, a solar power generation device includes a fixed frame 1, on which a bidirectional vibration platform is installed, and a dual-axis moving frame 2 that vibrates synchronously in both horizontal and vertical directions is connected to the bidirectional vibration platform.

[0037] It also includes a liquid storage tank 26 installed on the fixed frame 1, and a booster pump is connected to the liquid storage tank 26 through a liquid delivery pipe;

[0038] The bidirectional vibration platform includes a servo motor 14 mounted on a fixed frame 1. A first rotating wheel 15 is mounted on the output shaft end of the servo motor 14. Three first sector tooth segments 16 and first idle segments 17 are alternately arranged on the first rotating wheel 15.

[0039] A single-axis shift bracket 18 is slidably mounted on the fixed frame 1. Two first return springs 19 are mounted on the bottom surface of the single-axis shift bracket 18, and the other ends of the two first return springs 19 are fixedly connected to the fixed frame 1.

[0040] An internal rack plate 20 is installed on the single-axis shifter 18, and three first sector tooth segments 16 alternately mesh with the internal rack plate 20.

[0041] The central angles corresponding to the three first sector segments 16 are 30°, 40° and 50° respectively, and the central angles corresponding to the three first idle segments 17 are all 80°.

[0042] When it is necessary to clean and remove dust from the solar power generation film 11, the bidirectional vibration platform works and the speed of the servo motor 14 is adjusted to a high speed. In the cleaning mode, the solar power generation film 11 is exposed and the reciprocating frequency of the solar power generation film 11 is increased compared with the normal power generation state.

[0043] When the solar power generation film 11 is working normally, the servo motor 14 in the bidirectional vibration platform works periodically, and when the servo motor 14 is started periodically, it is in low speed mode.

[0044] In a preferred embodiment, the servo motor 14 rotates at 600-1400 rpm in cleaning mode and at 300-500 rpm in normal power generation mode.

[0045] When the servo motor 14 drives the first rotating wheel 15 to rotate, the three first sector tooth segments 16 on the first rotating wheel 15 with center angles of 30°, 40° and 50° respectively will alternately mesh with the inner rack plate 20 of the single-axis shift frame 18, and push the single-axis shift frame 18 to slide along the fixed frame 1 during the meshing process.

[0046] The first idle segment 17, with three center angles of 80°, provides reset time for the single-axis shifter 18. At this time, the single-axis shifter 18 returns to its initial position under the elastic force of the two first reset springs 19 on the bottom surface, forming periodic horizontal vibration.

[0047] This design breaks through the limitations of traditional solar energy devices that vibrate at a fixed or uniform speed, and achieves variable amplitude horizontal vibration through the first sector tooth segment 16 with different center angles;

[0048] like Figure 6 , Figure 7 and Figure 8 As shown, the dual-axis shift frame 2 is slidably connected to the single-axis shift frame 18. A second return spring 21 is installed between the dual-axis shift frame 2 and the single-axis shift frame 18. A second rotating wheel 22 is rotatably installed on the single-axis shift frame 18. The second rotating wheel 22 is driven by the servo motor 14.

[0049] A tensioning platform 29 is slidably mounted on the fixed frame 1. A set of tensioning springs 30 is installed between the tensioning platform 29 and the fixed frame 1. A tensioning wheel 31 is rotatably connected to the tensioning platform 29. A second toothed belt is drivingly connected between the first rotating wheel 15 and the tensioning wheel 31. A differential shaft 32 is rotatably mounted on the single-axis shifting frame 18. The differential shaft 32 is drivingly connected to the second toothed belt.

[0050] The differential shaft 32, the first pulley 15, and the tensioner 31 are all equipped with second pulleys that are connected to the second toothed belt;

[0051] Both the differential shaft 32 and the second rotating wheel 22 are equipped with linkage bevel gears, and the two linkage bevel gears mesh orthogonally.

[0052] Two second sector tooth sections 23 and two second idle sections 24 are alternately arranged on the second rotating wheel 22. An outer rack plate 25 is installed on the dual-axis shift frame 2. The two second sector tooth sections 23 alternately mesh with the outer rack plate 25. A set of support springs 41 is hinged between the dual-axis shift frame 2 and the fixed frame 1.

[0053] The center angles corresponding to the two second sector segments 23 are 50° and 70° respectively, and the center angles corresponding to the two second idle segments 24 are both 120°.

[0054] After the servo motor 14 drives the first rotating wheel 15 to rotate, the power is transmitted to the tension wheel 31 of the tensioning table 29 through the second toothed belt. The tension spring 30 on the side of the tensioning table 29 can automatically extend and retract according to the tightness of the toothed belt, and adjust the position of the tension wheel 31 in real time to avoid the second toothed belt from slipping. The tension wheel 31 then drives the differential shaft 32 on the single-axis shift frame 18 to rotate.

[0055] The differential shaft 32 converts the horizontal power into the vertical power through two orthogonally meshing bevel gears, driving the second wheel 22 to rotate.

[0056] The two second sector tooth segments 23 on the second rotating wheel 22, with center angles of 50° and 70°, alternately mesh with the outer rack plate 25 of the dual-axis shift frame 2, pushing the dual-axis shift frame 2 to slide along the single-axis shift frame 18. At the same time, the second return spring 21 is stretched and reset, driving the dual-axis shift frame 2 to reciprocate and vibrate, forming a two-way vibration of horizontal and vertical with the horizontal vibration of the single-axis shift frame 18.

[0057] The automatic tensioning structure of the tensioning table 29 realizes the stable transmission of the driving force of the second tooth when the single-axis shifter 18 is displaced. When the single-axis shifter 18 is displaced, the shape of the second tooth belt changes accordingly.

[0058] The bidirectional vibration platform alternates between a first sector tooth segment 16 with three center angles of 30°, 40° and 50° and a first idle segment 17 with three center angles of 80°. Combined with the high-speed drive of the servo motor 14 in cleaning mode, it achieves small, medium and large gradient amplitudes, solving the cleaning blind zone problem that exists in traditional fixed amplitude.

[0059] The small amplitude of the 30° first sector segment 16 can gently shake off floating dust and thin dust, preventing dust from spreading. The medium amplitude of the 40° first sector segment 16 can shake off the tightly attached middle layer of dust. The large amplitude of the 50° first sector segment 16 can impact stubborn stains, increasing the rate of stubborn dust removal compared to the fixed amplitude, achieving cleaning of the entire area without dead corners.

[0060] Secondly, under the high-speed drive of the cleaning mode, the variable amplitude vibration alternates between small, medium and large amplitudes, which not only retains the strong dust removal capability of large amplitude, but also avoids the solar power generation film 11 being in a large amplitude vibration state for a long time by using the buffer of small and medium amplitude, thereby reducing the damage rate of the solar power generation film 11 under high speed, and taking into account both strong dust removal and protection of the solar power generation film 11.

[0061] The first sector tooth section 16, the second sector tooth section 23, the first idle section 17, the second idle section 24, the inner rack plate 20, and the outer rack plate 25 are all provided with an anti-impact coating. The anti-impact coating is made of polyurethane and has a thickness of 0.15mm.

[0062] The anti-impact coating is used to reduce meshing impact and noise;

[0063] The dual-axis shifter 2 is equipped with a pitching frame 3;

[0064] like Figure 5 As shown, an electric rotator 33 is installed on the dual-axis shifter 2. A rotator 34 is installed on the rotation output end of the electric rotator 33. The rotator 34 is hinged to the pitch frame 3. An angle adjustment push rod 35 is hinged between the pitch frame 3 and the rotator 34.

[0065] The illumination angle sensor 38 transmits the illumination data to the microcontroller 37, which controls the electric rotator 33 to drive the rotating frame 34 to rotate, thus realizing the horizontal 360° rotation of the pitch frame 3.

[0066] Simultaneously control the extension and retraction of the angle adjustment push rod 35 to push the pitch frame 3 to rotate around the hinge point with the slewing frame 34, thereby adjusting the pitch angle;

[0067] The dual-dimensional adjustment of horizontal rotation and pitch breaks through the limitation of traditional pitch adjustment only. It can accurately track the sun's trajectory and ensure that the solar power generation film 11 always receives sunlight at the best angle, thus improving power generation efficiency.

[0068] The tilting frame 3 is equipped with display racks 4 on both sides. A scissor telescopic mechanism is installed between the tilting frame 3 and the two display racks 4. Two transmission modules are installed on the tilting frame 3, and the two transmission modules are connected to the two scissor telescopic mechanisms respectively.

[0069] The scissor-type telescopic mechanism includes a set of scissor frame units 5 that are hinged in sequence. The display frame 4 and the tilting frame 3 are both slidably connected to a movable hinge seat 42 and are both fixedly installed with a fixed hinge seat 43. The movable hinge seat 42 and the fixed hinge seat 43 are both hinged to the scissor frame unit 5 at adjacent positions.

[0070] like Figure 3 and Figure 4As shown, the transmission module includes a drive motor 6 mounted on the pitch mount 3 and a drive screw 44 rotatably connected to the pitch mount 3. The drive screw 44 is threadedly connected to the movable hinge seat 42 on the pitch mount 3. The output shaft end of the drive motor 6 is connected to the drive screw 44 via a third toothed belt.

[0071] The microcontroller 37 controls the start of the drive motor 6 of the transmission module. The drive motor 6 drives the drive screw 44 to rotate through the third toothed belt. The drive screw 44 drives the movable hinge seat 42 on the pitch frame 3 to slide.

[0072] Both the drive screw 44 and the output shaft of the drive motor 6 are equipped with a third pulley that is connected to the third toothed belt.

[0073] The movable hinge seat 42 drives the scissor lift unit 5 to unfold or retract, thereby pushing the display frame 4 away from or closer to the tilt frame 3, and cooperating with the roller 8 to realize the unfolding and retraction of the solar power generation film 11;

[0074] The scissor-type telescopic mechanism has a stable structure. Through the hinge of multiple scissor frame units 5, it can achieve a wide range of smooth extension and retraction, avoiding the shaking of the display frame 4 that could cause wrinkles or damage to the solar power generation film 11. Compared with the rod-type telescopic mechanism, its stability is improved.

[0075] Furthermore, the telescopic structure of the scissor-type telescopic mechanism allows for flexible adjustment of the specifications of the device and the light-receiving area of ​​the solar power generation film 11, thereby facilitating the flexible transportation and deployment of the device.

[0076] Two guide rollers 7 are rotatably mounted on each display stand 4, and two rollers 8 and two brush shafts 9 are rotatably mounted on the tilting frame 3. A base belt 10 that fits with the guide rollers 7 is wound between the two rollers 8. A solar power generation film 11 is installed on the base belt 10. The two rollers 8 are linked by the first toothed belt, and the two brush shafts 9 are both connected to the first toothed belt drive.

[0077] Each of the two rollers 8 and the two brush shafts 9 is equipped with a first pulley that is connected to the first toothed belt;

[0078] During normal power generation, the solar power generation film 11 is in the unfolded state, and the drive motor 13 drives the roller 8 in a reciprocating working mode.

[0079] In severe weather conditions such as hail and sandstorms, the solar power generation film 11 is in a retracted state, and the installation area of ​​the non-solar power generation film 11 on the baseband 10 is exposed, thereby effectively protecting the solar power generation film 11.

[0080] Both brush shafts 9 are equipped with spiral brush blades 12 that are attached to the solar power generation film 11. The pitching frame 3 is equipped with a drive motor 13, and the output shaft end of the drive motor 13 is fixedly connected to a roller 8.

[0081] During normal power generation, the drive motor 13 drives one roller 8 to rotate, and drives another roller 8 to rotate synchronously through the first toothed belt, unfolding the base belt 10 and the solar power generation film 11. The drive motor 13 drives the roller 8 to rotate back and forth, causing the solar power generation film 11 to move slowly.

[0082] Meanwhile, during the power generation process of the solar power generation film 11, the first toothed belt drives the brush shaft 9 to rotate, and the spiral brush blades 12 adhere to the surface of the solar power generation film 11 to clean it;

[0083] In severe weather, the drive motor 13 rotates in reverse, the roller 8 retracts the solar power generation film 11, and the baseband 10 is exposed and protected from non-power generation areas.

[0084] The reciprocating roller 8, in conjunction with the spiral brush 12, achieves comprehensive cleaning of the solar power generation film 11. When the spiral brush 12 rotates, it generates axial cleaning force, pushing the dust to both sides, eliminating cleaning dead angles. Compared with the fixed brush, the cleaning effect is improved, and dust accumulation is avoided from affecting the light transmittance.

[0085] The retraction function under severe weather conditions uses the roller 8 to retract the solar power generation film 11, and the cut-resistant fabric base belt 10 resists impact and scratch, solving the problem of easy damage to traditional solar panels.

[0086] The fixed frame 1 is equipped with a control unit for adjusting the parameters of the bidirectional vibration platform and the drive motor 13.

[0087] The control unit includes a battery box 36 mounted on a fixed frame 1. The battery box 36 contains a storage battery. A microcontroller 37 is mounted on the end face of the battery box 36. A light angle sensor 38, a dust sensor 39, and a temperature sensor 40 are mounted on the pitch frame 3. The data output terminals of the light angle sensor 38, the dust sensor 39, and the temperature sensor 40 are electrically connected to the data receiving terminal of the microcontroller 37. The power output terminal of the storage battery is electrically connected to the power input terminal of the microcontroller 37. The power output terminals of the solar power generation film 11 are all electrically connected to the storage battery.

[0088] The light angle sensor 38, dust sensor 39, and temperature sensor 40 collect light data, dust concentration data, and equipment temperature data in real time, and transmit the data to the microcontroller 37.

[0089] The microcontroller 37 is model STM32F103. The light angle sensor 38, dust sensor 39, and temperature sensor 40 can all be customized or selected according to actual needs.

[0090] After analyzing the data, the microcontroller 37 automatically adjusts the speed of the servo motor 14 of the bidirectional vibration platform, the movement of the electric rotator 33 and the angle adjustment push rod 35, and the direction and speed of the drive motor 13.

[0091] Meanwhile, the electrical energy generated by the solar power film 11 is transmitted to the storage battery, which in turn powers the microcontroller 37, various motors, sensors, and other components, forming a self-sufficient energy cycle.

[0092] Through the control unit, fully automated intelligent control is achieved without human intervention, which can adapt to unattended scenarios and significantly reduce operation and maintenance costs. On the other hand, through the coordinated linkage of multiple sensors, it can respond to environmental changes in real time. Compared with traditional manually adjustable devices, it has improved environmental adaptability and response speed.

[0093] Furthermore, the built-in battery enables energy self-sufficiency, eliminating the need for an external power source. This not only reduces dependence on the power grid but also stores excess energy to power the control system on cloudy days or at night, ensuring continuous and stable operation of the device and improving energy utilization.

[0094] The baseband 10 is made of nylon cut-resistant fabric. The length of the baseband 10 is 7 times the maximum extension length of a single scissor telescopic mechanism, and the length of the solar power generation film 11 is 1.5 times the maximum extension length of a single scissor telescopic mechanism.

[0095] When the scissor telescopic mechanism is deployed, the cut-resistant fabric base belt 10, which is 7 times the maximum length of the scissor telescopic mechanism, can completely cover the area of ​​the display frame 4 and the tilting frame 3, and support the solar power generation film 11, which is 1.5 times the length, to be fully deployed.

[0096] When retracted, the baseband 10 can be completely wound by the roller 8 to wrap and protect the solar power generation film 11;

[0097] The cut-resistant fabric base tape 10 is high-strength, wear-resistant, and tear-resistant, which can support the solar power generation film 11 and resist external scratches, solving the problem of easy damage of traditional ordinary fabric base tape 10 and extending the service life of base tape 10;

[0098] The baseband 10 is 7 times the maximum extension length of a single scissor telescopic mechanism, ensuring no risk of stretching and breakage when fully extended, and completely wrapping the solar power generation film 11 when retracted, providing more comprehensive protection.

[0099] The 1.5 times length design of the solar power generation film 11 ensures that it covers the main light-receiving area when unfolded, avoids overlapping wrinkles when rolled up, and provides sufficient length for the reciprocating movement of the solar power generation film 11.

[0100] The outlet port of the booster pump is connected to a three-way hose 27. A fluid channel is fixedly opened inside the brush shaft 9. The fluid channel is rotatably connected to the three-way hose 27. Multiple sets of regularly distributed cleaning spray holes 28 are opened on the brush shaft 9 and are connected to the fluid channel.

[0101] When the dust sensor 39 detects excessive dust, the microcontroller 37 starts the booster pump. The cleaning fluid in the storage tank 26 is pressurized by the booster pump and transported by the three-way hose 27 to the fluid channel of the brush shaft 9, and then sprayed onto the surface of the solar power generation film 11 through the regularly distributed cleaning nozzles 28.

[0102] At the same time, the brush shaft 9 rotates, and the spiral brush blades 12 work with the cleaning liquid to scrub, achieving dual cleaning through spraying and brushing.

[0103] The variable amplitude vibration of this device, together with the spraying of cleaning fluid and the brushing of the brush shaft 9, forms a synergistic cleaning closed loop, which drives the solar power generation film 11 to vibrate irregularly, promoting the penetration of cleaning fluid into the gaps between dust particles and improving the overall cleaning efficiency.

[0104] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
