Description

Technical Field

[0001] This invention relates to the field of photovoltaic panel cleaning technology, and more specifically, to a photovoltaic panel anti-sand accumulation cleaning device adapted to windy and sandy environments. Background Technology

[0002] Photovoltaic panels, commonly known as solar panels, are devices that directly convert sunlight into electrical energy. Their core principle is the photovoltaic effect, where photons strike the semiconductor material in a solar cell, generating an electron flow that produces an electric current. With technological advancements and reduced production costs, photovoltaic power generation is becoming increasingly widespread, forming a crucial component of the global clean energy transition. The applications of photovoltaic panels are extensive, primarily in the following areas: First, residential photovoltaic (PV) systems are the most common application. As PV technology matures, more and more households are choosing to install PV panels on their roofs to generate electricity from solar energy, reducing electricity bills and generating profits by selling surplus power back to the grid. Second, large-scale commercial and industrial PV power plants are also gradually becoming an important part of renewable energy. Businesses and industrial parks utilize large rooftops or open land to build PV power plants for self-sufficient energy production, reducing dependence on traditional energy sources and generating revenue through electricity sales. Third, PV panels also have significant application value in remote areas, especially those without grid coverage. PV power generation provides local residents with a stable power supply, greatly improving their living conditions. In summary, as a representative of clean energy, photovoltaic panels have been widely adopted globally. With the continuous development of technology and the reduction of production costs, photovoltaic power generation is expected to play a greater role in the future and become an important driver of global energy transformation.

[0003] However, existing photovoltaic panels still have some problems in actual use. For example, when using photovoltaic panels in areas with heavy sandstorms, a large amount of sand and dust will accumulate on the surface of the photovoltaic panels. On the one hand, this affects the power generation efficiency of the photovoltaic panels, and on the other hand, it will also damage the photovoltaic panels. The existing cleaning methods are all manual cleaning, which is inefficient and labor-intensive, and is not suitable for cleaning large-scale photovoltaic panels. Summary of the Invention

[0004] To overcome the above deficiencies, the present invention provides an adaptive photovoltaic panel anti-sand accumulation cleaning device for wind and sand environments that overcomes or at least partially solves the above technical problems.

[0005] This invention is implemented as follows: This invention provides a photovoltaic panel anti-sand cleaning device that adapts to wind and sand environments, including a column, an installation frame fixedly installed on the outer surface of the column, a positioning rod tightly installed inside the installation frame, an installation base integrally welded to the bottom end of the column, a positioning frame installed on the outer surface of the positioning rod, a frame installed at the top of the positioning frame, a photovoltaic panel arranged inside the frame, and an external frame fixedly installed on the outside of the frame. The external frame has guide rails fixedly installed on the top surfaces of both sides of the frame. Baffles are fixedly installed at both ends of the guide rails. A self-cleaning mechanism is provided on the top of the guide rails. A dust collection box is fixedly installed inside the external frame. The dust collection box is equipped with a dust scraping mechanism and a dust discharge mechanism.

[0006] In a preferred embodiment, the self-cleaning mechanism includes a frame, the number of which is four, the four frames are symmetrically distributed in pairs, and a rotating shaft is rotatably installed inside the two sets of frames, and a cleaning roller is fixedly installed on the outer surface of the rotating shaft.

[0007] In a preferred embodiment, rollers are installed at both ends of the frame, a motor is fixedly installed on one side of the frame, and pulleys are fixedly installed on the output end of the motor and one side of the rollers. A transmission toothed belt is sleeved between each of the pulleys, and the outer surface of the rollers is in contact with the top surface of the guide rail.

[0008] In a preferred embodiment, a mounting shaft is rotatably mounted in the middle of the frame, and pulleys are fixedly mounted on the outer surface of the mounting shaft and the output end of the motor. A transmission belt is sleeved between the two pulleys.

[0009] In a preferred embodiment, a first transmission gear is fixedly mounted on the outer surface of the mounting shaft, and a second transmission gear is fixedly mounted on the outer surface of the first rotating shaft, wherein the second transmission gear meshes with the first transmission gear.

[0010] In a preferred embodiment, a top reinforcing bar is fixedly installed at the top of the frame, and side reinforcing bars are fixedly installed on both sides of the frame.

[0011] In a preferred embodiment, the dust scraping mechanism includes two partitions, which are symmetrically installed on the inner walls of both sides of the dust collection box and form a through groove in the middle. A cleaning frame is provided above the dust collection box, and a discharge port is provided on the bottom surface of the cleaning frame. A guide frame is fixedly installed inside the discharge port and is movably inserted into the through groove. The cleaning frame has an inverted triangular structure, and multiple protrusions are fixedly installed on both inner walls of the cleaning frame. The multiple protrusions are irregularly distributed.

[0012] In a preferred embodiment, a plurality of springs are provided between the cleaning rack and the partition, with one end of each spring fixedly connected to the outer surface of the cleaning rack and the other end of each spring fixedly connected to the top surface of the partition.

[0013] In a preferred embodiment, the dust removal mechanism includes an arc-shaped frame that is movably engaged inside the dust collection box and located below a partition. The top surface of the partition is connected to the outer side of the discharge port by multiple connecting plates. A second rotating shaft is rotatably installed inside the dust collection box, and a spiral blade is fixedly installed on the outer surface of the second rotating shaft. The outer surface of the spiral blade is in contact with the inner wall of the arc-shaped frame.

[0014] In a preferred embodiment, a dust exhaust pipe is fixedly connected to the bottom surface of the arc-shaped frame. One end of the dust exhaust pipe extends to the outside of the dust collection box and is movably inserted into the bottom surface of the dust collection box. A second motor is fixedly installed on one side of the dust collection box. The output end of the second motor is fixedly connected to one end of a second rotating shaft. A touch switch is fixedly connected to the bottom surface of the dust collection box, and the touch switch and the second motor are engaged with each other.

[0015] The photovoltaic panel anti-sand accumulation cleaning device adapted to wind and sand environments provided by this invention has the following beneficial effects: 1. By setting up a self-cleaning mechanism and controlling the start of motor one, the motor one drives pulley one to rotate. Since a transmission toothed belt is sleeved between the two pulleys one, it can synchronously drive the roller to roll on the top surface of the guide rail, thereby driving the cleaning roller to move. The cleaning roller contacts the top surface of the photovoltaic panel. When the cleaning roller moves on the top of the photovoltaic panel, it can clean the dust adhering to the top of the photovoltaic panel and move towards the inclined end of the photovoltaic panel until the cleaning roller moves to the dust collection box, so that the cleaned dust falls into the dust collection box for unified collection, thereby achieving the purpose of automatically cleaning the dust on the top of the photovoltaic panel.

[0016] 2. By setting up a dust scraping mechanism, when the cleaning roller moves above the cleaning frame, it can squeeze the cleaning frame, so that the outer surface of the cleaning roller is inside the cleaning frame. At this time, the motor continues to rotate, and the dust adhering to the cleaning roller is limited by the obstruction of the baffle made of ordinary material. The dust can be discharged into the interior of the cleaning frame through the protrusions and discharged downward through the discharge port. On the one hand, it can clean the cleaning roller, and on the other hand, the inverted triangular structure of the cleaning frame can prevent the dust entering the dust collection box from floating upward from the inside of the dust collection box, avoiding secondary pollution after cleaning.

[0017] 3. By setting up a dust removal mechanism, when the cleaning roller squeezes the cleaning frame, the cleaning frame will move downward, which in turn drives the discharge port downward. The connecting plate allows the arc-shaped frame to move downward inside the dust collection box until the bottom surface of the arc-shaped frame contacts the top of the touch switch. The touch switch can then control the second motor to start, which in turn drives the second rotating shaft and the spiral blades to rotate above the arc-shaped frame. When dust falls through the discharge port onto the top of the arc-shaped frame, the rotation of the second rotating shaft and the spiral blades will discharge the dust outward through the connecting plate. In other words, the dust that falls into the dust collection box and the dust that falls during the cleaning of the photovoltaic panels can be automatically discharged outward during the cleaning of the cleaning roller, thereby further increasing the overall practicality of the device.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Reference Figures 1-8 The present invention provides a technical solution: a photovoltaic panel anti-sand cleaning device for wind and sand environment, including a column 1, an installation frame 2 fixedly installed on the outer surface of the column 1, a positioning rod 3 tightly installed inside the installation frame 2, an installation base 4 integrally welded to the bottom end of the column 1, a positioning frame 5 installed on the outer surface of the positioning rod 3, a frame 6 installed at the top of the positioning frame 5, a photovoltaic panel 7 arranged inside the frame 6, and an external frame 8 fixedly installed on the outside of the frame 6. The top surfaces of both sides of the external frame 8 are fixedly installed with guide rails 9. Both ends of the guide rails 9 are fixedly installed with baffles 10. The top of the guide rails 9 is provided with a self-cleaning mechanism 12. The dust collection box 14 is fixedly installed inside the external frame 8. The dust collection box 14 is provided with a dust scraping mechanism 13 and a dust discharge mechanism 15.

[0023] In actual use, the photovoltaic panel 7 is first installed inside the frame 6, and then the frame 6 is fixedly installed with the positioning bracket 5 and the positioning rod 3. After installation, the mounting base 4 is fixed to the mounting surface with bolts. During the installation of the positioning rod 3, since the positioning rod 3 and the mounting bracket 2 are fastened together, the installation angle of the frame 6 and the photovoltaic panel 7 can be adjusted, thereby increasing the light-receiving area of ​​the photovoltaic panel 7 and increasing the power generation efficiency.

[0024] The self-cleaning mechanism 12 includes four frames 1201, which are symmetrically arranged in pairs. A rotating shaft 1208 is rotatably mounted inside each pair of frames 1201. A cleaning roller 1209 is fixedly mounted on the outer surface of the rotating shaft 1208. Rollers 1206 are mounted at both ends of each frame 1201. A motor 1204 is fixedly mounted on one side of each frame 1201. Pulleys 1205 are fixedly mounted on the output end of the motor 1204 and on one side of each roller 1206. A transmission toothed belt is fitted between each pulley 1205. 1207. The outer surface of roller 1206 is in contact with the top surface of guide rail 9. Mounting shaft 1210 is rotatably mounted in the middle of frame 1201. Pulley 1211 is fixedly mounted on the outer surface of mounting shaft 1210 and the output end of motor 1204. Transmission belt 1212 is sleeved between the two pulleys 1211. Transmission gear 1213 is also fixedly mounted on the outer surface of mounting shaft 1210. Transmission gear 1214 is fixedly mounted on the outer surface of rotating shaft 1208. Transmission gear 1214 and transmission gear 1213 mesh with each other.

[0025] When the photovoltaic panel 7 has been used for a long time in areas with heavy sandstorms, and its surface needs to be cleaned, it is only necessary to start the motor 1204. During startup, the motor 1204 drives the pulley 1205 to rotate. Since a toothed belt 1207 is fitted between the two pulleys 1205, it synchronously drives the roller 1206 to roll on the top surface of the guide rail 9, thereby driving the cleaning roller 1209 to move. The cleaning roller 1209 contacts the top surface of the photovoltaic panel 7. As the cleaning roller 1209 moves on the top of the photovoltaic panel 7, it removes the dust adhering to the top of the photovoltaic panel 7. The cleaning roller 1209 moves towards the inclined end of the photovoltaic panel 7 until it reaches the dust collection box 14, where the cleaned dust falls into the dust collection box 14 for unified collection. After cleaning is completed, the motor 1204 reverses to drive the roller 1206 to continue rolling, so that the self-cleaning mechanism 12 returns to its original position. The baffle 10 at the inclined end of the photovoltaic panel 7 is made of ordinary material, while the baffle 10 at the other end is a magnetic block. When the self-cleaning mechanism 12 returns to its original position, the magnetic block attracts and fixes the entire self-cleaning mechanism 12, ensuring the stability of the self-cleaning mechanism 12 when it is not cleaning.

[0026] Furthermore, when the motor 1204 rotates, it can also drive the mounting shaft 1210 to rotate under the action of the pulley 1211 and the transmission belt 1212, which in turn drives the transmission gear 1213 to rotate. Since the transmission gear 1213 and the transmission gear 1214 mesh with each other, they can drive the rotating shaft 1208 to rotate, which in turn drives the cleaning roller 1209 to rotate. That is, when the self-cleaning mechanism 12 moves as a whole, it can also synchronously drive the cleaning roller 1209 to roll on the top surface of the photovoltaic panel 7, thereby further improving the cleaning effect on the top of the photovoltaic panel 7 and allowing the cleaned dust to be better discharged into the dust collection box 14.

[0027] A top reinforcing rod 1202 is fixedly installed at the top of the frame 1201, and side reinforcing rods 1203 are fixedly installed on both sides of the frame 1201. The top reinforcing rod 1202 and the side reinforcing rods 1203 make the connection between the two sets of frames 1201 more stable, which greatly improves the overall movement stability of the self-cleaning mechanism 12 and the overall strength of the self-cleaning mechanism 12.

[0028] The dust scraping mechanism 13 includes two partitions 1301. The two partitions 1301 are symmetrically installed on the inner walls of the two sides of the dust collection box 14, and a through groove is separated in the middle. A cleaning frame 1302 is provided above the dust collection box 14. A discharge port 1305 is opened on the bottom surface of the cleaning frame 1302. A guide frame 1303 is fixedly installed inside the discharge port 1305. The guide frame 1303 is movably inserted into the through groove. The cleaning frame 1302 has an inverted triangular structure. Multiple protrusions 1306 are fixedly installed on both sides of the inner wall of the cleaning frame 1302. The multiple protrusions 1306 are irregularly distributed. Multiple springs 1304 are provided between the cleaning frame 1302 and the partitions 1301. One end of the multiple springs 1304 is fixedly connected to the outer surface of the cleaning frame 1302, and the other end of the springs 1304 is fixedly connected to the top surface of the partitions 1301.

[0029] During operation, as the self-cleaning mechanism 12 moves, when the cleaning roller 1209 moves above the cleaning frame 1302, the cleaning roller 1209 can squeeze the cleaning frame 1302, so that the outer surface of the cleaning roller 1209 can be inside the cleaning frame 1302. At this time, the motor 1204 continues to rotate, and the baffle 10 of ordinary material is used to limit the movement. The dust adhering to the cleaning roller 1209 can be discharged into the interior of the cleaning frame 1302 through the protrusion 1306 and discharged downward through the discharge port 1305. On the one hand, the cleaning roller 1209 can be cleaned, and on the other hand, the inverted triangular structure of the cleaning frame 1302 can prevent the dust entering the dust collection box 14 from floating upward from the interior of the dust collection box 14, thus avoiding secondary pollution after cleaning.

[0030] The dust removal mechanism 15 includes an arc-shaped frame 1501, which is movably engaged inside the dust collection box 14 and located below the partition 1301. Multiple connecting plates 1506 connect the top surface of the partition 1301 to the outer side of the discharge port 1305. A second rotating shaft 1502 is rotatably mounted inside the dust collection box 14. Spiral blades 1503 are fixedly mounted on the outer surface of the second rotating shaft 1502, and the outer surface of the spiral blades 1503 is in contact with the inner wall of the arc-shaped frame 1501. A dust exhaust pipe 1505 is fixedly connected to the bottom surface of the arc frame 1501. One end of the dust exhaust pipe 1505 extends to the outside of the dust collection box 14 and is movably inserted into the bottom surface of the dust collection box 14. A second motor 1504 is fixedly installed on one side of the dust collection box 14. The output end of the second motor 1504 is fixedly connected to one end of the second shaft 1502. A touch switch 1507 is fixedly connected to the bottom surface of the dust collection box 14. The touch switch 1507 and the second motor 1504 are engaged with each other.

[0031] During operation, when the cleaning roller 1209 squeezes the cleaning frame 1302, the cleaning frame 1302 moves downward, which in turn drives the discharge port 1305 downward. The connecting plate 1506 allows the arc-shaped frame 1501 to move downward inside the dust collection box 14 until the bottom surface of the arc-shaped frame 1501 contacts the top of the touch switch 1507. At this point, the touch switch 1507 controls the second motor 1504 to start, thereby driving the second rotating shaft 1502 and the spiral blades 15... 03 rotates above the arc frame 1501. When dust falls above the arc frame 1501 through the discharge port 1305, it can be discharged outward through the connecting plate 1506 by the rotation of the rotating shaft 1502 and the spiral blade 1503. That is, when cleaning the photovoltaic panel 7, the dust that falls into the dust collection box 14 and the dust that is cleaned by the cleaning roller 1209 can be automatically discharged outward when cleaning the cleaning roller 1209, thereby further increasing the overall practicality of the device.

[0032] Specifically, the working process or principle of this adaptive photovoltaic panel anti-sand cleaning device for sandy environments is as follows: First, the photovoltaic panel 7 is installed inside the frame 6. Then, the frame 6 is fixedly installed to the positioning rod 3 via the positioning bracket 5. After installation, the mounting base 4 is fixed to the mounting surface using bolts. During the installation of the positioning rod 3, because the positioning rod 3 and the mounting sleeve 2 are tightly clamped, the installation angle between the frame 6 and the photovoltaic panel 7 can be adjusted. By controlling the start of the motor 1204, the motor 1204 drives the pulley 1205 to rotate. Since a transmission toothed belt 1207 is sleeved between the two pulleys 1205, it can... The synchronously driven roller 1206 rolls on the top surface of the guide rail 9, thereby driving the cleaning roller 1209 to move. The cleaning roller 1209 contacts the top surface of the photovoltaic panel 7. When the cleaning roller 1209 moves on the top of the photovoltaic panel 7, it can clean the dust adhering to the top of the photovoltaic panel 7 and move towards the inclined end of the photovoltaic panel 7 until the cleaning roller 1209 moves to the dust collection box 14, causing the cleaned dust to fall into the dust collection box 14 for unified collection. When the motor 1204 rotates, it can also drive the mounting shaft 1210 to rotate under the action of the pulley 1211 and the transmission belt 1212, thereby driving the transmission gear 1213 to rotate. Since the transmission gear 1213 and the transmission gear 1212 rotate together, the installation shaft 1210 rotates, which in turn drives the transmission gear 1213 to rotate. The gears 214 mesh with each other, thus driving the rotating shaft 1208 to rotate, which in turn drives the cleaning roller 1209 to rotate. This means that during the overall movement of the self-cleaning mechanism 12, the cleaning roller 1209 can also be synchronously driven to roll on the top surface of the photovoltaic panel 7, further improving the cleaning effect on the top of the photovoltaic panel 7 and allowing the cleaned dust to be better discharged into the dust collection box 14. When the motor 1204 rotates, it can also drive the mounting shaft 1210 to rotate under the action of the pulley 1211 and the transmission belt 1212, thereby driving the transmission gear 1213 to rotate. Because the transmission gear 1213 and the transmission gear 1214 mesh with each other, they can drive the... The rotating shaft 1208 rotates, thereby driving the cleaning roller 1209 to rotate. This means that while the self-cleaning mechanism 12 is moving as a whole, it also synchronously drives the cleaning roller 1209 to roll on the top surface of the photovoltaic panel 7, further improving the cleaning effect on the top of the photovoltaic panel 7 and allowing the cleaned dust to be better discharged into the dust collection box 14. As the self-cleaning mechanism 12 moves, when the cleaning roller 1209 moves above the cleaning frame 1302, it squeezes the cleaning frame 1302, so that the outer surface of the cleaning roller 1209 is inside the cleaning frame 1302. At this time, the motor 1204 continues to rotate, limited by the obstruction of the ordinary material baffle 10.The dust adhering to the cleaning roller 1209 can be discharged into the cleaning frame 1302 through the protrusion 1306 and discharged downward through the discharge port 1305. This achieves cleaning of the cleaning roller 1209 on the one hand, and the inverted triangular structure of the cleaning frame 1302 prevents dust entering the dust collection box 14 from floating upward from the inside of the dust collection box 14, avoiding secondary pollution after cleaning. When the cleaning roller 1209 squeezes the cleaning frame 1302, the cleaning frame 1302 will move downward, which in turn drives the discharge port 1305 to move downward. The connecting plate 1506 enables the arc frame 1501 to move downward inside the dust collection box 14 until the arc frame 1501... When the bottom surface of the device contacts the top of the touch switch 1507, the touch switch 1507 controls the start of the motor 1504, which in turn drives the rotating shaft 1502 and the spiral blade 1503 to rotate above the arc frame 1501. When dust falls through the discharge port 1305 onto the arc frame 1501, the rotation of the rotating shaft 1502 and the spiral blade 1503 discharges the dust outward through the connecting plate 1506. In other words, dust falling into the dust collection box 14 and dust collected by the cleaning roller 1209 during the cleaning of the photovoltaic panel 7 can be automatically discharged outward during the cleaning of the cleaning roller 1209, further increasing the overall practicality of the device.

[0033] It should be noted that motor 1204 and motor 2 1504 are existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition and principle are clear to those skilled in the art, so they will not be described in detail.
