Description

Technical Field

[0001] The invention relates to the field of photovoltaics, and in particular to protective equipment for photovoltaic solar panels. Background Art

[0002] With the development of the global economy and the growth of population, the demand for energy is increasing. The reserves of traditional fossil energy are limited and facing an increasingly severe depletion crisis. Photovoltaic solar panels use solar energy, an inexhaustible clean energy, to generate electricity, providing a new way to meet global energy needs and greatly alleviating the energy crisis. They have many advantages such as environmental protection and energy saving, strong sustainability, low maintenance costs, and high energy independence. With the continuous advancement of technology, the conversion efficiency of photovoltaic cells has gradually increased, and the production cost has continued to decline, prompting photovoltaic solar power generation to be more and more widely used in civil and industrial fields. Today, photovoltaic solar 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 people with clean and reliable electricity.

[0003] However, photovoltaic solar power generation equipment is generally installed on roofs or relatively open areas. Such environments are prone to strong winds due to the lack of shelter. When the photovoltaic panels are facing away from the wind, they are tilted at a certain angle. When strong winds blow to the back of the solar panels, it is very easy to overturn the photovoltaic panels, causing damage to the equipment. At the same time, because the photovoltaic panels are exposed to the sun for a long time, their temperature is high. When the temperature of the photovoltaic panels rises, the carrier concentration and mobility inside the semiconductor material will change, resulting in a decrease in 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, the power generation efficiency will decrease by about 0.4%-0.5% for every 1°C increase in temperature. Summary of the invention

The number of the air collecting ducts is multiple and they are symmetrically distributed left and right. The airflow is gradually squeezed and accelerated by the inner wall of the air collecting duct during the process of entering from the air inlet end to the air outlet end, thereby forming an airflow with higher pressure and flow rate. When the airflow is sprayed onto the back of the scooping plate, it can also form a thrust to drive the water wheel to rotate, thereby increasing the rotation speed of the water wheel, making the flow of water entering the heat transfer pipe larger, and accelerating the heat dissipation efficiency.

[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.

[0018] Preferably, the interior of the mounting frame is provided with a plurality of three-way heat dissipation holes which are symmetrically distributed along the left and right sides, and both ends of the three-way heat dissipation holes are connected to the outside of the mounting frame, and the other end of the three-way heat dissipation holes extends to the side surface of the photovoltaic panel. External cold air enters through the outer end of the three-way heat dissipation holes, passes through the interior to take away the hot air generated by the side wall of the photovoltaic panel, and then flows out from the other outer end, thereby realizing a rapid exchange of cold and hot gases inside and outside, greatly improving the heat dissipation effect, reducing the temperature of the photovoltaic panel, and thereby improving the power generation efficiency.

[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. A protective device for photovoltaic solar panels. When the airflow passes through the upper surface of the wind pressure plate, the airflow on both sides will be collected and squeezed by the wind collecting duct to form a high-speed airflow. The high-speed airflow blows to the back of the scooping plate on the water wheel, so that the water wheel is not only driven to rotate by the second shaft, but also driven and rotated by the thrust provided by the high-speed airflow. Under the action of the double force, the rotation speed of the water wheel is faster, and the flow rate of water entering the heat pipe is larger, which accelerates the heat dissipation efficiency. In addition, the heat dissipation device can also convert wind energy into electrical energy through a generator and store it in a battery to achieve energy storage, and automatically release electrical energy in windless weather, so that the motor intervenes and drives the water wheel to continue to rotate for heat dissipation. It is not only more environmentally friendly and greatly reduces the cost of use, but also ensures that water cooling can be achieved under windy and windless conditions, thereby improving the continuity and efficiency of equipment heat dissipation.

[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 scooping plate 15. The left and right sides of the mounting frame 1 are fixedly connected with a lifting ear 25. The inner wall of the lifting ear 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 distributed in a circumferential annular array. The arc-shaped fan 13 is bent 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. A groove is provided inside the water wheel 14. The scooping plate 15 is located in the groove and is distributed in a circumferential direction.

[0042] In this embodiment, in strong wind weather, first loosen the limit nut 11, then hold the handle 10 and turn the screw rod 9. During the rotation of the screw rod 9 in the pull rod 8, pull the pull rod 8 up and down or downward to make it move vertically. During the vertical movement of the pull rod 8, the plurality of third rotating shafts 26 are driven to rotate in the corresponding wind pressure plate 5, so that the wind pressure plate 5 rotates in the mounting frame 1 through the first rotating shaft 6, so that the wind pressure plate 5 tilts backward within the angle range of 15° to 75°, and then tighten the limit nut 11 so that the screw 9 no longer rotates, so that the angle of the wind pressure plate 5 is achieved. When strong wind blows from the back of the photovoltaic panel 2, the airflow squeezes the upper surface of the wind pressure plate 5 so that the wind pressure plate 5 provides a downward pressure, thereby pressing the mounting frame 1 downward to prevent it from being overturned by the wind, making it more stable and improving the safety of the equipment.

After being lifted, the water is introduced into the water inlet end of the heat pipe 16 and flows into the interior of the heat pipe 16, realizing heat exchange with the back of the mounting frame 1, and then flows into the water tank 18 through the water outlet end of the heat pipe 16 through the return pipe 17 and mixes with the water in the water tank 18, so as to cool the heated water again, realize water circulation and cool the hot water at the same time, thereby greatly improving the energy-saving and environmental protection performance of the equipment.

[0043] Embodiment 2

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

[0045] The wind stabilizing 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 duct 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 scooping plate 15. The water cooling component includes a heat 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 pipe 16. A filter screen 19 is provided at the water inlet of the heat pipe 16. The filter screen 19 is detachably connected to the heat pipe 16. The inner wall of the heat pipe 16 is provided with a plurality of equally spaced arc-shaped heat conducting fins 20. 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. The drain pipe 23 is connected to the inside of the water tank 18. A sloped water collecting plate 21 is provided on the inner wall of the water tank 18. The slope of the sloped water collecting plate 21 is 10°. The rear end of the return pipe 17 The water outlet is located below the sloped water collecting plate 21, and the upper surface of the sloped water collecting plate 21 is provided with a baffle 22 symmetrically distributed on the left and right, and water holes are provided inside the baffle 22. Openings are formed between the two ends of the sloped 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 battery 31 is fixedly provided on the right surface of the generator 30. A motor 32 is fixedly provided on the right surface of the water tank 18, and a speed sensor 33 is installed at the right end of the second rotating shaft 12. The input end of the generator 30 is transmission-connected to the second rotating shaft 12, and the output end of the motor 32 is transmission-connected to the second rotating shaft 12. The output end of the generator 30 is electrically connected to the battery 31 through a wire, and the output end of the battery 31 is electrically connected to the motor 32 through a wire.

[0047] In this embodiment, in strong wind weather, the second rotating shaft 12 rotates under the drive of wind energy and the electric energy generated by the generator 30 will be stored in the battery 31. When there is no wind or weak wind, the speed sensor 33 detects that the second rotating shaft 12 cannot rotate, and the starter motor 32 intervenes to drive the second rotating shaft 12 through the electric energy provided by the battery 31, thereby ensuring that water cooling can be achieved under windy and windless conditions, improving the continuity and efficiency of equipment heat dissipation, making full use of wind energy, realizing alternating drive of wind drive and electric drive, and greatly reducing the whole process. The electric energy loss of the electric drive is reduced. At the same time, before the water flows into the heat pipe 16, it is first filtered by the filter 19 arranged at the water inlet end of the heat pipe 16 to prevent excessive impurities in the water from precipitating on the inner wall of the heat pipe 16 to cause blockage or poor water flow, thereby causing a decrease in heat dissipation performance. When the water flows through the heat pipe, it fully contacts with the arc-shaped heat-conducting fins 20 arranged on the inner wall, increasing the contact area with the water, so that the water flow can take away the 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 can be added automatically. The water in the water tank 18 is collected in advance by the method of natural precipitation. During the rainfall process, raindrops fall on the upper surface of the sloped water collection plate 21. Due to its unique slope design, the water drops naturally slide along the slope to the baffle 22 to be filtered, preventing excessive impurities in the water tank 18. Then, the water drops fall into the water tank from both ends of the sloped water collection plate 21, thereby realizing the collection of rainwater. When the water in the water tank 18 evaporates, the water vapor floats to the lower surface of the water tank 18 and is blocked, and then gathers into water droplets, which fall into the water below again through the slope, which not only reduces the loss of water resources caused by water evaporation, but also reduces the loss of water resources caused by water evaporation. Loss is achieved, water resources are saved, and the water in the water tank 18 is covered by the water collecting plate 21 to avoid the water stored in the water tank 18 being exposed to direct sunlight and causing the temperature to be too high, thereby achieving a better cooling effect in the water circulation process. At the same time, external cold air enters through the outer end of the three-way heat dissipation hole 28, passes through the interior and takes away the hot air generated by the side wall of the photovoltaic power generation panel 2, and then flows out from the other end of the three-way heat dissipation hole 28, realizing a rapid exchange of cold and hot gases inside and outside, greatly improving the heat dissipation effect, reducing the temperature of the photovoltaic power generation panel 2, and then improving the power generation efficiency.
