Technical Field

[0002] Photovoltaic panels are often displayed at an inclined angle, so that the surface of the photovoltaic panel faces the sunlight to improve the light energy absorption rate. It refers to a power generation system that uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. Photovoltaic hot spots are an attachment phenomenon on photovoltaic panels. Because photovoltaic panels are tilted at an angle, a layer of shielding will be formed on their low-side areas. For example, when rainwater is discharged from the low-side area of the photovoltaic panel over time, dirt or spots will form in the low-side area. These spots are similar to forming a load in this area of the photovoltaic panel. When the photovoltaic panel diode generates electricity, energy loss will be generated in this area, causing the heat in this area to be significantly higher than other areas, resulting in premature aging of the photovoltaic panel. In addition, due to the energy loss, the output power of the photovoltaic cell assembly will be reduced to a certain extent. Summary of the invention

The carrier faces vertically downward to support the base frame at an inclined angle. At the same time, the assembly cavity and the photovoltaic panel are displayed at an inclined angle through the base frame. The water pipe is located on the inclined low side of the assembly cavity. When the water outlet of the water pipe is drained, it can push the lifting seat to rise along the guide rod, and the lifting seat drives the scraper rod to rise;
[0007] The lifting seat is close to the inclined lower side of the assembly cavity and close to the top of the drain port of the water pipe. The side of the base frame is provided with a leakage hole, which is far away from the lifting seat and located on the rising path of the lifting seat.
[0008] As a further preferred embodiment, a float cavity is provided on the lifting seat, the float cavity faces the inner end of the water pipe, the float cavity is filled with a spring, the other end of the spring is connected to the assembly cavity, and the lifting seat is supported by the spring to form a floating space between the lifting seat and the assembly cavity, the water outlet of the water pipe faces the floating space, and when the water outlet of the water pipe discharges water outward, rainwater enters the floating space and pushes the lifting seat to gradually rise.
[0009] As a further preferred embodiment, a partition is fixed in the assembly cavity, the bottom end of the partition is connected to the water pipe and close to the water outlet of the water pipe, the top end of the partition is parallel to the inner side of the guide rod and extends along the length direction of the guide rod, and a partition cavity is formed between the partition and the side of the assembly cavity. When water flows out of the water outlet of the water pipe, rainwater enters the partition cavity and as the water level of the rainwater rises, the lifting seat is pushed to rise along the guide rod.
[0010] As a further preferred embodiment, the scraper rod is connected to a rubber strip on one side facing the photovoltaic panel, and a first chamfered surface is provided on the inclined lower side of the rubber strip facing the base frame. The length of the scraper rod extends from one side of the photovoltaic panel to the other side of the photovoltaic panel, and an angle is formed between the first chamfered surface and the front face of the photovoltaic panel.
[0011] As a further preferred embodiment, the rubber strip is provided with a second chamfered surface on the other side opposite to the first chamfered surface, and the second chamfered surface is tangent to the surface of the photovoltaic panel.

[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] Rainwater falls into the socket from the interface, and flows into the water pipe after gathering in the socket. As the amount of rainwater in the socket gradually increases, the amount of rainwater flowing into the water pipe will also increase. The rainwater flows along the water pipe to the bottom of the lifting seat, and as the rainwater gathers more and more at the bottom of the lifting seat, the water pressure at the bottom of the lifting seat will become higher and higher. Since the size of the socket is larger than the lumen of the water pipe, and the socket is located at the high end of the water pipe, according to the principle of water level difference, when the water pressure at the bottom of the lifting seat becomes higher and higher, it will push the lifting seat to rise along the guide rod. In addition, since the side of the base frame is provided with a slideway located on the outside of the lifting seat, a scraper rod is connected to the lifting seat. The scraper rod passes through the slideway and bends on the surface of the photovoltaic panel; therefore, when the lifting seat rises along the guide rod, it will bring the scraper rod up with it, and the inner surface of the scraper rod will move upward along the photovoltaic surface of the photovoltaic panel, which is equivalent to using the inner surface of the scraper rod to wipe the photovoltaic surface; on the contrary, when the rain stops, the rainwater in the water pipe will be drained, and the water outlet of the water pipe will no longer supply water to the bottom of the lifting seat, and the bottom of the lifting seat will lose the water pressure effect, and the gravity of the lifting seat is greater than the water pressure. At this time, the lifting seat will descend along the guide rod, and the lifting seat will bring the scraper rod down, and the inner surface of the scraper rod will move downward along the outside of the photovoltaic panel, which is equivalent to using the inner surface of the scraper rod to wipe the photovoltaic surface again. To solve the problem that the photovoltaic surface of the photovoltaic panel may form hot spots due to dirt or other attachments. Since hot spots are mostly formed on the low side area of the photovoltaic surface, the scraping and wiping action of the scraper rod only needs to be located in the low area of the photovoltaic surface. Although rainwater flushing can also clean dirt and other attachments, the present invention collects rainwater and uses it as the power of the scraper to wipe the dirt and other attachments on the low-lying area of the photovoltaic surface, which can further improve the wiping effect.

DETAILED DESCRIPTION
[0026] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.
[0027] In one embodiment, Figure 1-Figure 8 As shown: This embodiment provides an intelligent hot spot-free photovoltaic component, including a base frame 1, an assembly cavity 2 is provided on the front side of the base frame 1, a photovoltaic panel 3 is installed in the assembly cavity 2, the top surface of the photovoltaic panel 3 protrudes upward above the top surface of the base frame 1, a water pipe 4 is provided in the assembly cavity 2, the water pipe 4 is covered inside the photovoltaic panel 3, and the photovoltaic panel 3, in addition to receiving light and absorbing light energy, is also used to cover the water pipe 4. Photovoltaic power generation is a prior art, and its specific power generation principle will not be repeated in the present invention.
[0028] The back of the base frame 1 is provided with a carrier 14, and the top surface of the carrier 14 is provided with an inclined surface. The carrier 14 is welded to the back of the base frame 1 through the inclined surface. The carrier 14 is vertically downward, and is used to support the base frame 1 at an inclined angle. At the same time, the assembly cavity 2 and the photovoltaic panel 3 are displayed at an inclined angle through the base frame 1. In actual use, a support frame is installed on the carrier 14, and the bottom of the support frame is fixed on the building. The photovoltaic panel 3 is supported by the carrier 14 at an inclined angle to meet the requirements of light absorption. Figure 1 , Figure 4As shown, the water pipe 4 is located on the inclined lower side of the assembly cavity 2. When the water outlet of the water pipe 4 discharges water, it can push the lifting seat 6 to rise along the guide rod 5, and the lifting seat 6 drives the scraper rod 13 to rise;
[0029] like Figure 1 , Figure 4 as well as Figure 5 As shown, in addition to the above-mentioned power generation function, the photovoltaic module is also equipped with a vertical guide rod 5 on one side of the inner cavity of the assembly cavity 2. The guide rod 5 is located on one side of the water outlet of the water pipe 4. A lifting seat 6 is installed on the guide rod 5. The lifting seat 6 is a high-density foam. The lifting seat 6 is filled with a sliding sleeve 19. The sliding sleeve 19 is loosely fitted on the guide rod 5. The lifting seat 6 can be lifted and lowered along the guide rod 5 through the sliding sleeve 19. One end of the water inlet of the water pipe 4 extends along one side of the assembly cavity 2 and is close to the lifting seat 6. The water pipe 4 The other end of the assembling chamber 2 is penetrated to the outside of the assembly chamber 2 and is installed with a socket 7, on which an interface 8 is provided; on rainy days, rainwater falls into the socket 7 through the interface 8, and flows into the water pipe 4 after gathering in the socket 7. As the amount of rainwater in the socket 7 gradually increases, the amount of rainwater flowing into the water pipe 4 will also increase, and the rainwater flows along the water pipe 4 to the bottom of the lifting seat 6. As the rainwater gathers more and more at the bottom of the lifting seat 6, the water pressure at the bottom of the lifting seat 6 will become higher and higher. Since the size of the socket 7 is larger than the lumen of the water pipe 4, and the socket 7 The lifting seat 6 is located at the high end of the water pipe 4. Therefore, according to the principle of water level difference, when the water pressure at the bottom of the lifting seat 6 becomes higher and higher, the lifting seat 6 will be pushed up along the guide rod 5. Since the side of the bottom frame 1 is provided with a slideway 12 located outside the lifting seat 6, the lifting seat 6 is connected with a scraper rod 13, and the scraper rod 13 passes through the slideway 12 and is bent on the surface of the photovoltaic panel 3; therefore, when the lifting seat 6 rises along the guide rod 5, the scraper rod 13 will be brought up with it, and the inner surface of the scraper rod 13 will go up along the outer surface (photovoltaic surface) of the photovoltaic panel 3. , which is equivalent to using the inner surface of the scraper 13 to wipe the photovoltaic surface; on the contrary, when the rain stops, the rainwater in the water pipe 4 is drained, and the outlet of the water pipe 4 no longer supplies water to the bottom of the lifting seat 6. The bottom of the lifting seat 6 loses the water pressure effect, and the gravity of the lifting seat 6 is greater than the water pressure. At this time, the lifting seat 6 will descend along the guide rod 5, and the lifting seat 6 will bring the scraper 13 down. The inner surface of the scraper 13 will go down along the outside (photovoltaic surface) of the photovoltaic panel 3, which is equivalent to using the inner surface of the scraper 13 to wipe the photovoltaic surface again. To solve the problem that the photovoltaic surface of the photovoltaic panel 3 may form hot spots due to dirt or other attachments. Since hot spots are mostly formed on the low side area of the photovoltaic surface, the scraping and wiping action of the scraper 13 is only located in the low area of the photovoltaic surface. Although rainwater flushing can also clean dirt and other attachments, the present invention collects rainwater and uses it as the power of the scraper 13 to wipe the dirt and other attachments on the low area of the photovoltaic surface, which can further improve the wiping effect.
[0030] like Figures 5 to 7As shown, the lifting seat 6 is close to the inclined lower side of the assembly cavity 2 and above the drain port of the water pipe 4. A drainage hole 15 is opened on the side of the base frame 1. The drainage hole 15 is far away from the lifting seat 6 and is located on the rising path of the lifting seat 6. When rainwater is discharged to the bottom of the lifting seat 6 through the drain port and the water pressure is greater than the gravity of the lifting seat 6, the lifting seat 6 will be pushed up. When the water level pushes the lifting seat 6 to the position of the drainage hole 15, the rainwater is discharged outward from the drainage hole 15, and the lifting seat 6 stops rising, limiting the rising range of the lifting seat 6. Since hot spots are mostly formed on the low-level area of the photovoltaic surface, the lifting seat 6 can be raised by a certain distance to wipe off dirt and other attachments to avoid the generation of hot spots.
[0031] like Figure 6 , Figure 7 As shown, a floating cavity 9 is provided on the lifting seat 6, and the floating cavity 9 faces the inner end of the water pipe 4. The floating cavity 9 is filled with a spring 10, and the other end of the spring 10 is connected to the assembly cavity 2. Through the support of the spring 10 on the lifting seat 6, a floating space 11 is formed between the lifting seat 6 and the assembly cavity 2. The outlet of the water pipe 4 faces the floating space 11. When the outlet of the water pipe 4 is drained outward, rainwater enters the floating space 11 to push the lifting seat 6 to gradually rise. Under the support of the spring 10, the bottom of the lifting seat 6 forms a floating space 11 for rainwater to enter. After the rainwater is discharged from the outlet of the water pipe 4, it enters the floating space 11, and gradually forms an upward water pressure in the floating space 11. As the water level continues to rise, the floating cavity 9 pushes the lifting seat 6 to gradually rise. The opening of the floating cavity 9 makes the lifting seat 6 light in weight, and can better act on the water pressure on the lifting seat 6, pushing the lifting seat 6 to complete the rising action, and the structure of the lifting seat 6 is more reasonable. The spring 10 limits the descending range of the lifting seat 6, and reserves the floating space 11 for the rainwater level to rise and form water pressure.
[0032] like Figure 4 , Figure 5 As shown, a partition 16 is fixed in the assembly chamber 2, the bottom end of the partition 16 is connected to the water pipe 4 and close to the water outlet of the water pipe 4, the top end of the partition 16 is parallel to the inner side of the guide rod 5 and extends along the length direction of the guide rod 5, and a partition 17 is formed between the partition 16 and the side of the assembly chamber 2. When water flows out of the water outlet of the water pipe 4, rainwater enters the partition 17, and as the water level of the rainwater rises, the lifting seat 6 is pushed up along the guide rod 5. When the water level of rainwater rises and the lifting seat 6 is pushed up by the rising water pressure, rainwater will also enter the partition 17. As the water level of rainwater in the partition 17 continues to rise, when the lifting seat 6 is pushed to the bottom to reach the position of the drain hole 15, the excess rainwater will be discharged outward through the drain hole 15 to reduce the water pressure. The lifting seat 6 stops rising.
[0033] like Figure 8As shown, a rubber strip is connected to the scraper bar 13 on one side facing the photovoltaic panel 3, and a first chamfered surface 18 is provided on the inclined lower side of the rubber strip facing the base frame 1. The length of the scraper bar 13 extends from one side of the photovoltaic panel 3 to the other side of the photovoltaic panel 3, and an angle is formed between the first chamfered surface 18 and the front of the photovoltaic panel 3. The first chamfered surface 18 is provided to form a line contact between the rubber strip and the photovoltaic surface, thereby reducing the friction resistance between the rubber strip and the photovoltaic surface, and reducing the resistance when rainwater enters the floating cavity 9 and pushes the lifting seat 6 to rise.
[0034] like Figure 1 As shown, the rubber strip is provided with a second chamfered surface 20 on the other side opposite to the first chamfered surface 18, and the second chamfered surface 20 is tangent to the surface of the photovoltaic panel 3. When rainwater washes dirt and other attachments to a lower position on the photovoltaic surface, the dirt and other attachments are discharged to a lower position through the second chamfered surface 20, and even if the scraper 13 exists, it can avoid the interception effect of the dirt and other attachments on the discharge.
[0035] An intelligent hot spot-free photovoltaic system includes a controller 24 installed on a base frame 1, a distance sensor 21 installed in a compartment 17, the distance sensor 21 is close to a leakage hole 15, the distance sensor 21 is connected to the controller 24, the probe of the distance sensor 21 faces a lifting seat 6, a discharge pipe 22 is installed on a water pipe 4 vertically and passes through the lower side of the base frame 1, and a solenoid valve 23 connected to the controller 24 is installed on the discharge pipe 22. Intelligent control is realized. Rainwater falls into the socket 7 from the interface 8. Since the socket 7 is at a high position and higher than the water pipe 4, the rainwater will flow into the water pipe 4. As more and more rainwater flows into the socket 7, the water pressure of the rainwater in the water pipe 4 will increase. At the same time, the water pressure acting on the float chamber 9 when it flows into the floating space 11 will also increase. The high water pressure pushes the water level in the floating space 11 to rise, and the rising water level pushes the lifting seat 6 to rise. When the lifting seat 6 rises to the bottom and reaches the position of the leakage hole 15, the excess rainwater will be discharged outward through the leakage hole 15 and the pressure will be relieved. The water level will no longer rise, and the lifting seat 6 will no longer rise. At this time, the scraper rod 13 rises with the lifting seat 6 to wipe and clean the dirt on the photovoltaic surface. At the same time, the rising end of the lifting seat 6 approaches the distance sensor 21 and reaches the distance When the distance sensor 21 reaches the detection range of the probe, the distance sensor 21 sends a command to the module in the controller 24 and instructs the solenoid valve 23 to open automatically. The rainwater in the water pipe 4 is discharged outward from the discharge pipe 22. The water level of the rainwater in the floating space 11 drops completely. The lifting seat 6 drops rapidly along the guide rod 5. The lifting seat 6 drives the scraper 13 to drop rapidly. The scraper 13 wipes the photovoltaic surface again. The rainwater is collected again in the receiving seat 7. When the water pressure provided by the rainwater to the water pipe 4 is greater than the deadweight of the lifting seat 6 again, the lifting seat 6 is pushed up again. When it rises to the detection range of the probe close to the distance sensor 21, the rainwater in the water pipe 4 is completely discharged again. By analogy, the lifting seat 6 is frequently lifted and lowered, and the scraper 13 frequently cleans the photovoltaic surface. Intelligentization is realized, which greatly reduces the possibility of hot spots on the photovoltaic surface.
[0036] It should be further explained that the principle of intelligent control of solenoid valve is a prior art, and the present invention will not elaborate on this technology. However, the application of its intelligent control in the present invention plays a supplementary role in improving the intelligence of the solution of the present invention.
[0037] It should be further explained that another embodiment can be set up. A water pump is set up in the photovoltaic system to regularly replenish water in the socket 7 to replace rainwater. When the water pump fills the socket 7 with water, it can also flow into the water pipe 4 from the socket 7. As the amount of water supplied increases, the water pressure in the water pipe 4 will also increase. The lifting seat 6 can also be pushed up by draining water to the floating space 11. The water pump is controlled by the controller 24. When the rising end of the lifting seat 6 approaches the distance sensor 21 and reaches the probe detection range of the distance sensor 21, the controller 24 instructs the solenoid valve 23 to open automatically and controls the water pump to cut off the power. The rainwater in the water pipe 4 is discharged outward from the discharge pipe 22, the water level in the floating space 11 decreases, the lifting seat 6 no longer rises, and the water pump stops working, and the lifting seat 6 automatically descends. In this embodiment, the socket 7 is set up to receive rainwater. While providing water source non-artificially, it can also enable the lifting seat 6 to carry the scraper 13 to complete the above action, and at the same time, it can also achieve the above effect, saving water source and saving water pump. In addition, the manufacturing and maintenance costs are relatively high.
