Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic protection, and specifically to a hail-proof device for photovoltaic panels in a photovoltaic power station and its control system. Background Art

[0002] With the increasing global emphasis on renewable energy, photovoltaic power generation, as a clean and renewable energy form, has received extensive attention and application. However, during the actual operation of a photovoltaic power station, photovoltaic panels face various challenges from the natural environment, and among them, the damage caused by hail weather to photovoltaic panels is particularly significant. Hail, with its high-speed impact force and hard texture, often causes serious physical damage to photovoltaic panels, thereby affecting the power generation efficiency and operation stability of the photovoltaic power station. To address this challenge, the photovoltaic industry has started to actively explore and develop various hail-proof devices.

[0003] For example, in the patent document with the prior art publication number CN222441626U, this patent document belongs to the technical field of protection devices for photovoltaic panels in a photovoltaic power station, and specifically to a hail-proof device for photovoltaic panels in a photovoltaic power station, including a support frame. The upper end of the support frame is fixedly connected with a mounting plate, the upper end of the mounting plate is fixedly connected with a photovoltaic panel, a protection frame and a fixing component are arranged at the upper end of the mounting plate, the mounting plate is connected with the protection frame through the fixing component, the photovoltaic panel is located inside the protection frame, a protection plate and a buffer component are arranged inside the protection frame, the protection frame is slidably connected with the protection plate, and the protection plate is made of a transparent material. By setting the fixing component in the present utility model, when it is necessary to disassemble the protection frame, the insertion rod is moved away from the positioning hole of the positioning plate, thereby releasing the limitation on the protection frame, facilitating the removal of the protection frame from the mounting plate, and thus facilitating the replacement of the internal photovoltaic panel, improving the work efficiency.

[0004] Although the existing hail-proof technology provides an effective protection barrier for photovoltaic panels by cleverly setting the protection frame and successfully withstanding the direct impact of hail, and with the design of the fixing component, the installation and disassembly of the protection frame become convenient. However, in actual application scenarios, when hail violently impacts the protection frame, a large amount of broken ice will be generated, and these broken ice often adhere to and accumulate on the surface of the protection frame. Over time, these accumulated broken ice will gradually block the photovoltaic panel, seriously affecting its lighting effect, and thus reducing the power generation efficiency and overall performance of the photovoltaic power station. Therefore, this application proposes a hail-proof device for photovoltaic panels in a photovoltaic power station and its control system. Summary of the Invention

[0012] Preferably, the jitter component includes a sliding rod fixedly connected to the bottom of the rubber block. A secondary pipe is communicated with the top of the air cylinder, and the end of the sliding rod away from the rubber block extends into the interior of the secondary pipe and is slidably connected to it.

[0013] Preferably, a plurality of multi-leaf movable vanes are rotatably connected inside the auxiliary pipe, and one ends of the plurality of multi-leaf movable vanes close to each other are rotatably connected to the outer surface of the sliding rod. Springs for driving the multi-leaf movable vanes to reset are sleeved at the joints of the plurality of multi-leaf movable vanes and the auxiliary pipe. The plurality of multi-leaf movable vanes together form a circle for blocking the gas flow in the auxiliary pipe.

[0014] Preferably, the auxiliary assembly includes a plurality of cranks rotatably connected to the bottom of the transparent vane. A plurality of positioning frames are fixedly connected to the outer surface of the glass through pipe below the transparent vane. The top of each of the plurality of positioning frames is slidably connected to a top plate rotatably connected to one end of the crank. A plurality of top handles that can abut against the air compression plate are rotatably connected to the outer surface of the glass through pipe.

[0015] Preferably, a tension spring fixedly connected to the top plate is fixedly connected to the top of the positioning frame.

[0016] Preferably, sliding frames are fixedly connected to both ends of the outer surface of the glass through pipe, and both ends of the transparent vane are arranged inside the sliding frames and slidably connected thereto.

[0017] Preferably, a support for adjusting its angle is fixedly connected to the bottom of the photovoltaic panel.

[0018] The present invention also provides a control system for a hail-proof device of a photovoltaic panel in a photovoltaic power station, including:

[0019] A controller, which is arranged inside the mounting frame, coordinately controls the jitter assembly, the auxiliary assembly and the exhaust system, and a data transmission module is arranged inside it;

[0020] A photosensitive resistor array, which is used to monitor the solar azimuth angle in real time, and feeds the monitoring data back to the controller through the data transmission module. The controller adjusts the angle of the photovoltaic panel according to the solar azimuth angle;

[0021] An ultrasonic hail sensor, which is used to monitor the hail situation in real time and is linked with the processor. When hail is detected, the controller quickly starts the adjustment assembly.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Monitor the solar azimuth angle in real time. Push the moving plate through the electric push rod, drive the transmission column to rotate the multi-impeller, link the glass through-tube to tilt the transparent leaf plate, so that the light is focused on the central area of the photovoltaic panel, reduce the light reflection loss, adapt to seasonal changes, extend the effective lighting time. The combined design of the glass through-tube and the transparent leaf plate realizes the automatic closing protection against hail and heavy snow, effectively buffers the impact force, and protects the photovoltaic panel from damage. The transparent characteristic of the transparent leaf plate ensures that the lighting is not affected, further improving the power generation efficiency. The rotating design of the multi-impeller not only disperses the impact of hail, but also realizes the flexible adjustment of the tilt angle of the transparent leaf plate through the adjustment component to adapt to different wind directions and hail landing points, ensuring all-round protection. The rotation of the multi-impeller not only helps with protection, but also drives the gas in the air cylinder to be transported to the exhaust pipe through the connecting pipe and the air delivery pipe and finally discharged from the exhaust hole through the interaction of the transmission beads and the spring piston rod. This gas flow design can blow away the hail and snow sliding on the transparent leaf plate, preventing them from accumulating on the surface of the photovoltaic panel, thus maintaining the cleanliness and high-efficiency power generation of the photovoltaic panel.

[0024] 2. When hail impacts the transparent leaf plate, it will trigger a chain reaction of the auxiliary component, causing the air pressure plate to move in the glass through-tube and squeeze the gas. These gases are then evenly ejected through the discharge port, directly and quickly dispersing the hail and snow accumulated on the surface of the transparent leaf plate, effectively preventing their accumulation, not only improving the cleanliness of the photovoltaic panel, but also ensuring the continuous and efficient power generation of the photovoltaic panel under bad weather. The auxiliary component constitutes a flexible transmission system. When the transparent leaf plate is displaced due to hail impact, this system will immediately respond and push the air pressure plate to move. This self-adaptive ability ensures that the device can quickly and effectively protect itself when hail strikes. The cooperation between the carriage and the rubber block provides a vibration effect for the glass through-tube, making the hail and snow attached to the surface of the transparent leaf plate and the glass through-tube more likely to fall off under the vibration effect. The components such as the sliding rod, auxiliary pipe and multi-leaf movable piece in the jitter component further enhance this vibration effect. When the gas flows in the auxiliary pipe, it will push the multi-leaf movable piece to move, and then drive the sliding rod and the rubber block to vibrate. The combination of this vibration and the gas ejection makes the removal effect of hail and snow more significant. The gas flow in the device is not only used to disperse hail and snow, but also used to drive the movement of the jitter component and the multi-leaf movable piece. This ingenious utilization not only improves the overall efficiency of the device, but also reduces the waste of energy. Especially when the spring piston rod moves up and down, it will drive the gas in the air cylinder to be transported back and forth in the auxiliary pipe. This circulating flow of gas provides continuous power for the vibration and blowing functions of the device. Brief Description of the Drawings

Detailed implementation manners

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0040] Embodiment 1: Please refer to Figure 1 , Figure 2 and Figure 3 , the present invention provides a technical solution: a hail-proof device for photovoltaic panels in a photovoltaic power station, including a photovoltaic panel 100, a support 101 for adjusting its angle is fixedly connected to the bottom of the photovoltaic panel 100. The support 101 is used to be fixed to the ground while other parts are adjustable to ensure that the photovoltaic panel obtains the best light angle in different seasons. Through the adjustment function of the support 101, the device can effectively resist hail impact and protect the safe and stable operation of the photovoltaic panel. The support 101 is made of high-strength materials and has good weather resistance to ensure no deformation during long-term use.

[0041] Please refer to Figure 4 , Figure 5 and Figure 11 , it also includes a glass through-tube 200, which is configured with a plurality of them all arranged above the photovoltaic panel 100, and transparent leaf plates 201 that can be mutually closed are arranged on the outer surfaces of the plurality of glass through-tubes 200. An installation frame 202 is fixedly connected to the top of the photovoltaic panel 100, and a multi-impeller 203 fixedly connected to the plurality of glass through-tubes 200 is rotatably connected inside the installation frame 202. An adjustment component for driving the rotation of the plurality of multi-impellers 203 is arranged on the top of the installation frame 202, and an exhaust pipe 210 is fixedly connected to the top of the photovoltaic panel 100. An exhaust component adapted to the plurality of multi-impellers 203 is arranged inside the installation frame 202. Through the cooperation of the glass through-tube 200 and the transparent leaf plate 201, automatic closing protection can be realized, effectively buffering the hail impact force. At the same time, the transparent characteristic of the transparent leaf plate 201 ensures that the light is not affected and improves the power generation efficiency. The rotating design of the multi-impeller 203 further disperses the impact and enhances the protection effect. At the same time, the adjustment component can change the inclination angle of the plurality of transparent leaf plates 201 to adapt to different wind directions and hail landing points to ensure all-round protection. Its inclination can realize self-cleaning so that the hail slides off without accumulation. In cooperation with the exhaust component, the sliding hail can be blown away.

[0042] Among them, the adjustment component includes an electric push rod 204 fixedly connected to the top of the mounting frame 202. Inside the mounting frame 202 and above multiple multi-impellers 203, a moving plate 205 is provided. The bottom of the moving plate 205 is fixedly connected with multiple groups of transmission columns 206, and multiple groups of transmission columns 206 are all placed on the tops of multiple multi-impellers 203 to drive the multi-impellers 203 to rotate. The output end of the electric push rod 204 is fixedly connected to the moving plate 205. By setting the transmission columns 206 to cooperate with multiple multi-impellers 203, multiple multi-impellers 203 can be effectively driven to rotate synchronously, achieving precise adjustment, ensuring that the protection device can operate efficiently under different weather conditions, and extending the service life of the photovoltaic panel.

[0043] Please refer to Figure 6 , Figure 7 and Figure 10 , the exhaust component includes multiple air cylinders 207 fixedly connected to the bottom of the mounting frame 202, and a connecting pipe 214 is commonly connected between the multiple air cylinders 207. One end of the connecting pipe 214 is connected to an air delivery pipe 215 that is connected to the exhaust pipe 210. Multiple exhaust holes 212 for exhausting gas are provided on the side of the exhaust pipe 210 facing the photovoltaic panel 100. The tops of the multiple air cylinders 207 are all slidably connected with spring piston rods 208 adapted to them. The tops of the multiple spring piston rods 208 are all rotatably connected with transmission beads 209 that are in contact with the multiple multi-impellers 203. By setting multiple air cylinders 207, the transportation of gas can be effectively realized, which enables the transportation of gas when the transparent leaf plate 201 swings. The flowing gas can quickly blow away the hailstones that slide off the transparent leaf plate 201, preventing them from accumulating on the surface of the photovoltaic panel 100.

[0044] Specifically, when in use, first install the mounting frame 202 on the top of the photovoltaic panel 100. At this time, multiple transparent vanes 201 are in the same horizontal state. The photoresistor array 211 on the surface of the glass through-tube 200 can monitor the solar azimuth angle in real time, so as to adjust the tilt angle of the glass through-tube 200 to focus the light on the center of the photovoltaic panel 100. The moving plate 205 can be driven by the driving electric push rod 204 to move, so that the transmission column 206 drives multiple multi-impellers 203 to rotate, and then drives the glass through-tube 200 to rotate, thereby changing the tilt angle of the transparent vanes 201, making the light focus on the surface of the photovoltaic panel 100. When a mixture of hail and heavy snow comes and impacts the multiple transparent vanes 201, the electric push rod 204 can be continuously opened to make it expand and contract, thereby driving the multiple multi-impellers 203 to rotate back and forth, so as to swing the multiple transparent vanes 201, making the snow and hail attached to the surface of the transparent vanes 201 fall under force onto the surface of the photovoltaic panel 100. At the same time, when the multi-impellers 203 rotate, the transmission beads 209 will be pulled to move, making the spring piston rod 208 move downward, thereby squeezing the gas in the air cylinder 207 to pass through the connecting pipe 214 and then through the air delivery pipe 215 to be delivered into the exhaust pipe 210, so that the gas is discharged through the multiple exhaust holes 212 and blown onto the surface of the photovoltaic panel 100, blowing away the snow and hail.

[0045] In summary, by monitoring the solar azimuth angle in real time, the electric push rod 204 is used to push the moving plate 205, driving the transmission column 206 to rotate the multi-impellers 203, and linking the glass through-tube 200 to tilt the transparent vanes 201, so that the light is focused on the central area of the photovoltaic panel 100, reducing the light reflection loss, adapting to seasonal changes, and extending the effective lighting time. The combined design of the glass through-tube 200 and the transparent vanes 201 realizes the automatic closing protection against hail and heavy snow, effectively buffers the impact force, and protects the photovoltaic panel from damage. The transparent characteristic of the transparent vanes 201 ensures that the lighting is not affected, further improving the power generation efficiency. The rotating design of the multi-impellers 203 not only disperses the impact of hail, but also realizes the flexible adjustment of the tilt angle of the transparent vanes 201 through the adjustment component to adapt to different wind directions and hail landing points, ensuring all-round protection. The rotation of the multi-impellers 203 not only helps with protection, but also, through the interaction of the transmission beads 209 and the spring piston rod 208, drives the gas in the air cylinder 207 to be delivered to the exhaust pipe 210 through the connecting pipe 214 and the air delivery pipe 215, and finally discharged from the exhaust holes 212. This gas flow design can blow away the hail and snow sliding on the transparent vanes 201, preventing them from accumulating on the surface of the photovoltaic panel 100, thus keeping the photovoltaic panel clean and highly efficient in power generation.

[0046] Embodiment 2: Please refer to Figure 8 、 Figure 9 and Figure 12, the present invention also provides a technical solution, which is different from the technical solution of Embodiment 1: A hail-proof device for photovoltaic panels in a photovoltaic power station further includes a drain opening 300, which is uniformly opened at the top of a plurality of glass through pipes 200, and a plurality of drain openings 300 all face a plurality of transparent leaf plates 201. A gas compression plate 301 for compressing the gas inside is rotatably connected inside the glass through pipe 200. An auxiliary component for driving the movement of the gas compression plate 301 is provided at the bottom of each of the plurality of transparent leaf plates 201. The auxiliary device compresses the gas by driving the gas compression plate 301, so that the gas is uniformly ejected through the drain opening 300, thereby quickly blowing away the hail and snow impacting on the surface of the transparent leaf plate 201 and effectively preventing their accumulation.

[0047] Furthermore, the auxiliary component includes a plurality of cranks 303 rotatably connected to the bottom of the transparent leaf plate 201. A plurality of positioning brackets 302 are fixedly connected to the outer surface of the glass through pipe 200 below the transparent leaf plate 201. The top of each of the plurality of positioning brackets 302 is slidably connected to a top plate 304 rotatably connected to one end of the crank 303. A plurality of top handles 306 that can contact the gas compression plate 301 are rotatably connected to the outer surface of the glass through pipe 200. One end of the top handle 306 away from the gas compression plate 301 is fixedly connected to a pressure handle 305 that can contact the top plate 304. A tension spring fixedly connected to the top plate 304 is fixedly connected to the top of the positioning bracket 302. Both ends of the outer surface of the glass through pipe 200 are fixedly connected with sliding brackets 307. Both ends of the transparent leaf plate 201 are arranged inside the sliding brackets 307 and are slidably connected thereto. By setting the crank 303, the top plate 304 and the positioning bracket 302 can be driven to move, and then the top handle 306 is pushed to contact the gas compression plate 301. It can be flexibly transmitted according to the movement of the transparent leaf plate 201, ensuring uniform gas ejection, effectively removing hail and snow, improving the power generation efficiency of the photovoltaic panel, extending the service life, and ensuring the stable operation of the power station.

[0048] Specifically, when hail strikes, operate a plurality of transparent leaf plates 201 to be in the same horizontal state to block the hail. When the hail impacts the surface of the transparent leaf plate 201, the transparent leaf plate 201 will be misaligned, causing it to slide on the surface of the sliding bracket 307 and then push one end of a plurality of cranks 303 downward, causing it to push the top plate 304 to move and drive one end of the pressure handle 305 to move downward, thereby driving the top handle 306 to move upward, causing the gas compression plate 301 to move upward and compress the gas in the glass through pipe 200 so that it is discharged through the drain opening 300, and then blown onto the surface of the transparent leaf plate 201, causing the hail fragments that have just fallen on the surface of the transparent leaf plate 201 to be blown away. At the same time, the inclination of the transparent leaf plate 201 will cause the hail to fall and be discharged.

[0049] It also includes a carriage 400, which is fixedly connected to the bottom of a plurality of glass through-tubes 200. A rubber block 401 adapted to it is slidably connected inside each of the plurality of carriages 400, and a jitter assembly is arranged at the bottom of the rubber block 401 to increase the dry friction between the rubber block 401 and the carriage 400. The jitter assembly includes a sliding rod 402 fixedly connected to the bottom of the rubber block 401. The top of its air cylinder 207 is communicated with an auxiliary pipe 403. One end of the sliding rod 402 away from the rubber block 401 extends into the interior of the auxiliary pipe 403 and is slidably connected to it. By setting the cooperation between the rubber block 401 and the carriage 400, vibrations can be applied to the glass through-tube 200, making it easier for hail and snow accumulation to fall off under the action of vibrations, further optimizing the hail prevention effect. And setting the jitter assembly can effectively cooperate with the rotation of the glass through-tube 200 to apply a vibration force to the glass through-tube 200.

[0050] Wherein, a plurality of multi-leaf movable pieces 404 are rotatably connected inside the auxiliary pipe 403, and one ends of the plurality of multi-leaf movable pieces 404 close to each other are rotatably connected to the outer surface of the sliding rod 402. Springs for driving the multi-leaf movable pieces 404 to reset are sleeved at the joints of the plurality of multi-leaf movable pieces 404 and the auxiliary pipe 403. The plurality of multi-leaf movable pieces 404 together form a circle to block the gas flow in the auxiliary pipe 403. By setting the multi-leaf movable pieces 404, the sliding rod 402 can be driven to move according to the gas flow, enhancing the jitter effect and ensuring that hail and snow accumulation quickly fall off during vibrations. When the gas flows, it will drive the joints of the plurality of multi-leaf movable pieces 404 and the sliding rod 402 to move, causing the multi-leaf movable pieces 404 to tilt and stagger to allow the gas to pass through.

[0051] Specifically, when the spring piston rod 208 moves up and down, it will drive the gas in the air cylinder 207 to continuously transport back and forth in the auxiliary pipe 403. When the gas passes through the multi-leaf movable pieces 404, it will push the central axis of the multi-leaf movable pieces 404 to move, and then pull the carriage 400 to cause a dislocation inside it for gas transportation. When the inside of the carriage 400 is dislocated, it will drive the sliding rod 402 to move, making the rubber block 401 continuously contact the inner wall of the carriage 400. Cooperating with the rotation of the glass through-tube 200, a vibration force is generated on the glass through-tube 200, thereby improving the snow removal effect of the transparent leaf plate 201.

[0052] In summary, when hail impacts the transparent vane 201, it triggers a chain reaction in the auxiliary component, causing the air compression plate 301 to move within the glass conduit 200 and compress the gas. These gases are then evenly ejected through the discharge port 300, directly and rapidly dispersing the hail and snow accumulating on the surface of the transparent vane 201, effectively preventing their accumulation. This not only improves the cleanliness of the photovoltaic panel but also ensures its continuous and efficient power generation under harsh weather conditions. The auxiliary component constitutes a flexible transmission system. When the transparent vane 201 is displaced due to hail impact, this system immediately responds by pushing the air compression plate 301 to move. This adaptive ability ensures that the device can quickly and effectively provide protection when hail strikes. The cooperation between the carriage 400 and the rubber block 401 provides a vibration effect for the glass conduit 200, making it easier for the hail and snow adhering to the surfaces of the transparent vane 201 and the glass conduit 200 to fall off under the action of vibration. Components such as the sliding rod 402, auxiliary pipe 403, and multi-leaf movable piece 404 in the jitter component further enhance this vibration effect. When the gas flows within the auxiliary pipe 403, it pushes the multi-leaf movable piece 404 to move, thereby driving the sliding rod 402 and the rubber block 401 to vibrate. The combination of this vibration and the ejection of the gas makes the effect of removing hail and snow more remarkable. The gas flow in the device is not only used to disperse hail and snow but also to drive the movement of the jitter component and the multi-leaf movable piece 404. This ingenious utilization not only improves the overall efficiency of the device but also reduces energy waste. Especially when the spring piston rod 208 moves up and down, it drives the gas in the air cylinder 207 to be transported back and forth within the auxiliary pipe 403. This circulating flow of gas provides a continuous power source for the vibration and blowing functions of the device.

[0053] Embodiment 3: Please refer to Figure 1 - Figure 13 , the present invention also provides a technical solution. The difference from the technical solution of Embodiment 1 is: A control system for a hail prevention device of a photovoltaic panel in a photovoltaic power station further includes a controller, which is disposed inside the mounting frame 202 and coordinately controls the jitter component, the auxiliary component, and the exhaust system. And a data transmission module is provided inside it, which can adopt the Arduino Mega 2560 model;

[0054] A photosensitive resistor array 211, which is used to real-time monitor the solar azimuth angle and feedback the monitoring data to the controller through the data transmission module. The controller adjusts the angle of the photovoltaic panel 100 according to the solar azimuth angle;

[0055] An ultrasonic hail sensor 213, which is used to real-time monitor the hail situation and is linked with the processor. When hail is detected, the controller quickly activates the adjustment component.

[0056] Specifically, the photoresistor array 211 can detect the solar azimuth angle, transmit the numerical value to the controller, and drive the electric push rod 204 to expand and contract, so as to adjust the inclination of multiple transparent vanes 201, making the photovoltaic panel always at the best light-receiving angle and improving the power generation efficiency; the ultrasonic hail sensor 213 monitors hail in real time. When hail is detected, the controller quickly starts the electric push rod 204 to expand and contract back and forth to drive the glass through-tube 200 to generate high-frequency vibrations, and cooperate with the dislocation movement of the rubber block 401 and the carriage 400 to accelerate the shedding of hail and snow, ensuring the cleanliness of the photovoltaic panel surface.

[0057] In summary, the photoresistor array 211 can monitor the solar azimuth angle in real time and feedback the data to the controller. The controller adjusts the angle of the photovoltaic panel 100 according to these data to ensure that the photovoltaic panel is always at the best light-receiving angle. Through the expansion and contraction of the electric push rod 204, the moving plate 205 and the transmission column 206 drive the glass through-tube 200 to rotate, thereby changing the inclination angle of the transparent vane 201, making the light focus on the surface of the photovoltaic panel and maximizing the power generation efficiency. The ultrasonic hail sensor 213 can monitor the hail situation in real time. Once hail is detected, the controller immediately starts the protection measures. The controller quickly starts the electric push rod 204 to expand and contract back and forth, driving the glass through-tube 200 to generate high-frequency vibrations, and cooperate with the dislocation movement of the rubber block 401 and the carriage 400 to accelerate the shedding of hail and snow, ensuring the cleanliness of the photovoltaic panel surface.

[0058] Working principle: When in use, first install the mounting frame 202 on the top of the photovoltaic panel 100. At this time, multiple transparent vanes 201 are in the same horizontal state, and the photoresistor array 211 on the surface of the glass through-tube 200 can monitor the solar azimuth angle in real time, so as to adjust the inclination angle of the glass through-tube 200 to make the light focus on the center of the photovoltaic panel 100. The electric push rod 204 can be driven to drive the moving plate 205 to move, so that the transmission column 206 drives multiple multi-impellers 203 to rotate, and then drives the glass through-tube 200 to rotate, thereby changing the inclination angle of the transparent vane 201, making the light focus on the surface of the photovoltaic panel 100;

[0059] When hail comes, operate multiple transparent vanes 201 to be in the same horizontal state to block the hail. When the hail impacts on the surface of the transparent vane 201, the transparent vane 201 will be misaligned, causing it to slide on the surface of the sliding frame 307, and then push one end of multiple cranks 303 to move downward, causing it to push the top plate 304 to move and drive one end of the pressure handle 305 to move downward, and drive the top handle 306 to move upward, causing the pressure plate 301 to move upward and squeeze the gas in the glass through-tube 200 to discharge it through the discharge port 300, and then blow it onto the surface of the transparent vane 201, so that the hail fragments just falling on the surface of the transparent vane 201 are blown away. At the same time, the inclination of the transparent vane 201 will cause the hail to fall and be discharged;

[0060] When hail and heavy snow mixedly strike the multiple transparent blades 201, the electric push rod 204 can be continuously turned on to extend and retract, thereby driving the multiple multi-impellers 203 to rotate back and forth, thereby swinging the multiple transparent blades 201, so that the snow and hail attached to the surface of the transparent blades 201 are forced to fall onto the surface of the photovoltaic panel 100. At the same time, when the multi-impeller 203 rotates, it will pull the transmission bead 209 to move so that the spring piston rod 208 moves downward, thereby squeezing the gas in the gas cylinder 207 through the connecting pipe 214 and through the gas delivery pipe 215 to the inside of the exhaust pipe 210, so that the gas is discharged through the multiple exhaust holes 212 and blown onto the surface of the photovoltaic panel 100, and the snow and hail are blown away;

[0061] When the spring piston rod 208 moves up and down, it will drive the gas in the gas cylinder 207 to be continuously transported back and forth in the auxiliary pipe 403. When the gas passes through the multi-leaf movable sheet 404, it will push the central axis of the multi-leaf movable sheet 404 to move, and then pull the slide 400 to cause the interior thereof to be misaligned for gas transportation. When the interior of the slide 400 is misaligned, it will drive the sliding rod 402 to move so that the rubber block 401 continuously contacts the inner wall of the slide 400, and cooperate with the rotation of the glass tube 200 to cause the glass tube 200 to generate a vibration force, thereby improving the snow removal effect of the transparent leaf plate 201.
