Description

Technical Field

[0001] The present invention relates to the field of photovoltaics, and specifically to a protective device for a photovoltaic solar power generation panel. Background Art

[0002] With the development of the global economy and the growth of the population, the demand for energy is increasing continuously. Traditional fossil energy reserves are limited and facing an increasingly severe depletion crisis. Photovoltaic solar power generation panels use solar energy, an inexhaustible and renewable clean energy source, for power generation, providing a new way to meet the global energy demand, greatly alleviating the energy crisis. It has many advantages such as environmental protection, energy conservation, strong sustainability, low maintenance cost, and high energy independence. Moreover, with the continuous progress of technology, the conversion efficiency of photovoltaic cells has been gradually improved, and the production cost has been continuously reduced, promoting the increasingly widespread application of photovoltaic solar power generation in civil and industrial fields. Nowadays, photovoltaic solar power generation panels have played an important role in many aspects such as household rooftop power generation, large-scale photovoltaic power stations, and commercial building integration, providing clean and reliable electricity for people.

[0003] However, photovoltaic solar power generation equipment is generally installed on rooftops or relatively open sites. In such an environment, due to the lack of shielding, the wind is very strong. When the photovoltaic power generation panel faces away from the oncoming wind, because the photovoltaic power generation panel has a certain inclination angle at this time, when the strong wind blows against the back of the solar power generation panel, it is very easy to overturn the photovoltaic power generation panel, causing damage to the equipment. At the same time, due to the long-term exposure of the photovoltaic power generation panel to sunlight, its temperature is relatively high. When the temperature of the photovoltaic panel rises, the carrier concentration and mobility inside the semiconductor material will change, resulting in a decrease in parameters such as the open-circuit voltage, short-circuit current, and fill factor of the battery, thereby reducing the overall power generation efficiency. For example, for crystalline silicon photovoltaic cells, for every 1°C increase in temperature, its power generation efficiency will approximately decrease by 0.4% - 0.5%. Summary of the Invention

[0014] Preferably, the back side of the corrugated heat sink is in contact with the heat pipe, a filter is provided at the water inlet at the upper end of the heat pipe, the filter is detachably connected to the heat pipe, a plurality of equally spaced arc-shaped heat conducting fins are fixedly connected to the inner wall of the heat pipe, the incoming water flow is filtered by the detachable filter, and the filter is convenient to replace to prevent the heat pipe from being blocked by excessive impurities in the water, and the arc-shaped heat conducting fins increase the contact area with the water flow, so that a large amount of heat can be quickly taken away, thereby improving the heat dissipation efficiency.

[0016] Preferably, a drain pipe is fixedly connected to the left side of the water tank, a sealing cover is threadedly connected to the side surface of the drain pipe, and the drain pipe is connected to the interior of the water tank for replenishing and replacing the water in the water tank.

[0019] (III) Beneficial effects

[0020] The present invention provides a protective device for photovoltaic solar panels. It has the following beneficial effects:

[0021] 1. This kind of protective equipment for photovoltaic solar panels adjusts the angle of the wind pressure plate installed on the mounting frame by adjusting the component, so that the wind pressure plate is tilted downward at a certain angle relative to the strong wind. When the strong wind blows from the back of the photovoltaic panel, the airflow squeezes the wind pressure plate to provide a downward pressure, thereby pressuring the mounting frame downward to prevent it from being overturned by the wind, making it more stable and improving the safety of the equipment.

[0022] 2. A protective device for a photovoltaic solar panel. The airflow passes between two wind pressure plates and reaches the arc fan to blow the arc fan. The arc fan rotates and drives the water wheels at both ends of the second rotating shaft to rotate. At the same time, the water collected in the water tank is scooped into the heat pipe. The water flows through the heat pipe to achieve heat dissipation and cooling on the back of the equipment, thereby improving the power generation efficiency. At the same time, when the water flows through the inside of the heat pipe, it fully contacts the arc heat-conducting fins arranged on the inner wall, increasing the area in contact with the water, so that the water flow can take away the heat faster, further improving the heat dissipation effect, and the hot water re-enters the water tank from the return pipe to achieve water circulation, thereby saving water resources.

[0023] 3. For the protection device of a photovoltaic solar panel, when the airflow passes through the upper surface of the wind pressure plate, the airflow on both sides will be collected by the air collecting pipe and compressed to form a high-speed airflow. This high-speed airflow blows to the back of the water scooping plate on the water wheel, causing the water wheel to rotate not only driven by the second rotating shaft but also pushed and rotated by the thrust provided by the high-speed airflow. Under the action of double gravity, the rotation speed of the water wheel is faster, the flow rate of water entering the heat conduction pipe is larger, and the heat dissipation efficiency is accelerated. Moreover, this heat dissipation device can also convert wind energy into electrical energy through a generator and store it in a storage battery to achieve energy storage, and automatically release electrical energy in windless weather. Then, through the intervention of a motor to drive the water wheel to continue rotating for heat dissipation, which is not only more environmentally friendly, greatly reduces the use cost, but also can ensure water-cooled heat dissipation under both windy and windless conditions, improving the continuity and efficiency of equipment heat dissipation.

Detailed implementation manners

[0037] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Embodiment 1

[0039] As Figure 1 - Figure 8 shown, the embodiment of the present invention provides a protection device for a photovoltaic solar power generation panel, including a mounting frame 1 and a photovoltaic power generation panel 2.

[0040] The wind stability device 3 includes a wind pressure component and an adjustment component. The wind pressure component includes a wind pressure plate 5, a first rotating shaft 6 and an air intake pipe 7. The first rotating shaft 6 passes through the inside of the wind pressure plate 5 and is rotatably connected to the mounting frame 1 at both ends. The upper surface of the wind pressure plate 5 is fixedly connected to the air intake pipe 7. The air intake pipe 7 is a semi-hollow frustum of a cone, and the diameter of the large end is twice that of the small end. The large end is the air inlet end, and the small end is the air outlet end. The number of air intake pipes 7 is multiple and symmetrically distributed on the left and right. The adjustment component includes a pull rod 8, a screw rod 9, a turning handle 10 and a fixing plate 29. A third rotating shaft 26 is fixedly connected to the side surface of the pull rod 8. The end of the third rotating shaft 26 is rotatably connected to the wind pressure plate 5. The lower end of the screw rod 9 is threadedly connected to the pull rod 8. The upper end of the screw rod 9 is fixedly connected to the turning handle 10. The side surface of the screw rod 9 is rotatably connected to the fixing plate 29. Both ends of the fixing plate 29 are fixedly connected to the mounting frame 1. A limit nut 11 is threadedly connected to the side surface of the screw rod 9. The angle range of the backward inclination of the wind pressure plate 5 is 15° to 75°.

[0041] The heat dissipation device 4 includes a driving component and a water cooling component. The driving component includes a second rotating shaft 12, an arc-shaped fan 13, a water wheel 14 and a water scooping plate 15. Lifting lugs 25 are fixedly connected to both the left and right sides of the mounting frame 1. The inner wall of the lifting lug 25 is rotatably connected to the second rotating shaft 12. The arc-shaped fan 13 is fixedly connected to the side surface of the second rotating shaft 12 and is circumferentially and annularly arranged. The arc-shaped fan 13 bends backward. The side surface of the second rotating shaft 12 is fixedly connected to the water wheel 14. The water wheels 14 are symmetrically distributed at the left and right ends of the arc-shaped fan 13. Grooves are provided inside the water wheels 14. The water scooping plates 15 are circumferentially distributed in the grooves to form a water tank. The water cooling component includes a heat conduction pipe 16, a return pipe 17 and a water tank 18. The back surface of the corrugated heat dissipation plate 27 is attached to the heat conduction pipe 16. The water outlet at the lower end of the heat conduction pipe 16 is fixedly connected to the return pipe 17. The rear end of the return pipe 17 is fixedly connected to the water tank 18. The rear surface of the water tank 18 is fixedly connected to the mounting frame 1. The heat conduction pipe 16 is communicated with the return pipe 17. The return pipe 17 is communicated with the water tank 18. A filter screen 19 is provided at the water inlet at the upper end of the heat conduction pipe 16. The filter screen 19 is detachably connected to the heat conduction pipe 16. A plurality of arc-shaped heat conduction fins 20 are fixedly connected to the inner wall of the heat conduction pipe 16 at equal intervals.

[0042] In this embodiment, in strong wind weather, first loosen the limit nut 11, then hold the handlebar 10 by hand and rotate the screw rod 9. During the rotation of the screw rod 9 in the pull rod 8, the pull rod 8 is pulled up or down, causing it to move vertically. During the vertical movement of the pull rod 8, it drives a plurality of third rotating shafts 26 to rotate in the corresponding wind pressing plates 5, causing the wind pressing plates 5 to rotate in the mounting frame 1 through the first rotating shaft 6. Thus, the wind pressing plates 5 tilt backward within an angle range of 15° to 75°. Then, tighten the limit nut 11 to stop the rotation of the screw rod 9, achieving the fixation of the angle of the wind pressing plates 5. When strong wind blows from the back of the photovoltaic panel 2, the airflow squeezes the upper surface of the wind pressing plates 5, causing the wind pressing plates 5 to provide a downward pressure, thereby causing the mounting frame 1 to be pressed downward, preventing it from being overturned by the wind force, making it more stable, improving the safety of the equipment. And when the airflow passes through the gaps between the wind pressing plates 5, it will be guided to the concave surface where the arc-shaped fan 13 bends backward, thereby driving the arc-shaped fan 13 to drive the second rotating shaft 12 and the water wheel 14 on the second rotating shaft 12 to rotate. At the same time, when the airflow passes through the upper surface of the wind pressing plates 5, due to the unique large-small opening design of the air collecting pipe 7, the airflow on both sides will be collected and squeezed by the air collecting pipe 7 to form a high-speed airflow. This high-speed airflow blows to the back of the water scooping plate 15 on the water wheel 14, causing the water wheel 14 to be not only driven to rotate by the second rotating shaft 12 but also pushed and rotated by the thrust provided by the high-speed airflow. Under the dual action of gravity, the rotation speed of the water wheel 14 is faster, the flow rate of water entering the heat conduction pipe 16 is larger, accelerating the heat dissipation efficiency. And this heat dissipation device 4 is driven by wind energy for its drive components in strong wind weather, not only saving electric energy but also being more environmentally friendly, greatly reducing the use cost. During the rotation of the water scooping plate 15 along with the water wheel 14, its unique arc-shaped structure scoops the water in the water tank 18 into the water tank formed by the water scooping plate 15 and the water wheel 14. After the water is lifted, it is introduced into the water inlet end of the heat conduction pipe 16 and flows into the interior of the heat conduction pipe 16 to achieve heat exchange with the back surface of the mounting frame 1. Then, it flows back into the water tank 18 through the water outlet end of the heat conduction pipe 16 and is mixed with the water in the water tank 18 to re-cool the heated water, realizing water circulation and at the same time cooling the hot water, greatly improving the energy-saving and environmental protection performance of the equipment.

[0043] Embodiment Two

[0044] As Figure 1 - Figure 12As shown in the figure, an embodiment of the present invention provides a protection device for a photovoltaic solar power generation panel, including a mounting frame 1 and a photovoltaic power generation panel 2. An installation groove is provided inside the mounting frame 1, and the installation groove is detachably connected to the photovoltaic power generation panel 2. A plurality of three-way heat dissipation holes 28 are symmetrically distributed along the left and right inside the mounting frame 1. Both ends of the three-way heat dissipation hole 28 communicate to the outside of the mounting frame 1, and the other end of the three-way heat dissipation hole 28 extends to the side surface of the photovoltaic power generation panel 2. A corrugated heat dissipation plate 27 is provided on the bottom inner wall of the installation groove. A generator 30 is fixedly connected to the right surface of the mounting frame 1, and a storage battery 31 is fixedly connected to the right surface of the generator 30. A wind stability device 3 and a heat dissipation device 4 are provided inside the mounting frame 1.

[0045] The wind stability device 3 includes a wind pressure component and an adjustment component for adjusting the angle. The wind pressure component includes a wind pressure plate 5, a first rotating shaft 6 and an air collecting pipe 7. The adjustment component includes a pull rod 8, a screw rod 9, a turning handle 10 and a fixing plate 29.

[0046] The heat dissipation device 4 includes a driving component and a water cooling component. The driving component includes a second rotating shaft 12, an arc-shaped fan 13, a water wheel 14 and a water scooping plate 15. The water cooling component includes a heat conduction pipe 16, a return pipe 17 and a water tank 18. The lower surface of the mounting frame 1 is fixedly connected to the heat conduction pipe 16. A filter screen 19 is provided at the water inlet of the heat conduction pipe 16, and the filter screen 19 is detachably connected to the heat conduction pipe 16. A plurality of equally spaced arc-shaped heat conduction fins 20 are provided on the inner wall of the heat conduction pipe 16. A drain pipe 23 is fixedly connected to the left side of the water tank 18. A sealing cover 24 is threadedly connected to the side surface of the drain pipe 23, and the drain pipe 23 communicates with the inside of the water tank 18. A slope-type water collecting plate 21 is provided on the inner wall of the water tank 18, and the slope of the slope-type water collecting plate 21 is 10°. The rear water outlet of the return pipe 17 is located below the slope-type water collecting plate 21. Baffles 22 are symmetrically distributed on the upper surface of the slope-type water collecting plate 21. Water holes are provided inside the baffles 22. Openings are formed between both ends of the slope-type water collecting plate 21 and the inner wall of the water tank 18. A generator 30 is fixedly provided on the right surface of the mounting frame 1, and a storage battery 31 is fixedly installed on the right surface of the generator 30. A motor 32 is fixedly provided on the right surface of the water tank 18. A rotation speed sensor 33 is assembled at the right end of the second rotating shaft 12. The input end of the generator 30 is in transmission connection with the second rotating shaft 12. The output end of the motor 32 is in transmission connection with the second rotating shaft 12. The output end of the generator 30 is electrically connected to the storage battery 31 through a wire. The output end of the storage battery 31 is electrically connected to the motor 32 through a wire.

[0047] In this embodiment, since the electric energy generated by the rotation of the second rotating shaft 12 driven by wind energy in strong wind weather is stored in the storage battery 31, when there is no wind or weak wind, when the rotation speed sensor 33 detects that the second rotating shaft 12 cannot rotate, the motor 32 is started to drive the second rotating shaft 12 by the electric energy provided by the storage battery 31, so as to ensure that water-cooled heat dissipation can be realized under both windy and windless conditions, improve the continuity and efficiency of equipment heat dissipation, make full use of wind energy, realize the alternating drive of wind drive and electric drive, greatly reduce the electric energy loss of full electric drive, and at the same time, before the water flow enters the inside of the heat conduction tube 16, it is first filtered by the filter screen 19 arranged at the water inlet end of the heat conduction tube 16 to prevent too many impurities in the water from precipitating on the inner wall of the heat conduction tube 16, causing blockage or poor water flow, and then resulting in the decline of heat dissipation performance. And when the water flow passes through the heat conduction tube, it fully contacts with the arc-shaped heat conduction fins 20 arranged on the inner wall, increasing the area of contact with water, enabling the water flow to take away heat faster, further improving the heat dissipation effect. At the same time, the water stored in the water tank 18 can not only be added manually, but also be collected in advance by natural precipitation. During the rainfall process, raindrops fall on the upper surface of the slope-type water collecting plate 21. Due to its unique inclined surface design, the water drops slide down along the inclined surface to the baffle 22 and are filtered to prevent too many impurities in the water tank 18, and then fall into the water tank from both ends of the slope-type water collecting plate 21 to realize the collection of rainwater. And when the water in the water tank 18 evaporates, the water vapor floating reaches the lower surface of the water tank and will be blocked, and then converges into water droplets and falls into the water below through the inclined surface again, not only reducing the loss of water resources caused by water evaporation and realizing the conservation of water resources, but also covering the water in the water tank 18 by the water collecting plate 21 to avoid the water stored in the water tank 18 being directly irradiated by the sun and resulting in too high a temperature, so that the cooling effect in the water circulation process is better. At the same time, the external cold air enters through the outer end of the three-way heat dissipation hole 28, takes away the hot air generated by the side wall of the photovoltaic power generation panel 2 inside, and then flows out from the other outer end of the three-way heat dissipation hole 28, realizing the rapid exchange of internal and external hot and cold gases, greatly improving the heat dissipation effect, reducing the temperature of the photovoltaic power generation panel 2, and then improving the power generation efficiency.
