A fixed flipping device for solar modules

Abstract

This invention discloses a fixed-rotation device for solar panels, relating to the field of new energy technology. It includes a self-cleaning component, comprising an L-shaped groove with rotating rollers rotatably mounted at the corners. The rollers are driven by an externally fitted synchronous belt. During use, rainwater flows over the surface of the photovoltaic panel and, guided by the bottom baffle, flows into a water tank through a bowl-shaped inlet. As day and night alternate, the double-sided mounting plate rotates under the action of a motor, allowing a gravity brush to self-clean dust and impurities on the photovoltaic panel surface during the rotation process, aided by a bottom rubber scraper and water spray holes. The cleaning water in this self-cleaning component comes from natural rainwater, and the movement and repositioning of the gravity brush rely solely on gravity. This allows for automatic self-cleaning of the photovoltaic panel surface through rotation during the day-night cycle.

Description

Technical Field

[0001] This invention relates to the field of new energy technology, specifically to a fixed and rotating device for solar modules. Background Technology

[0002] Streetlights with photovoltaic panels are currently the most common type of new energy streetlights. They use solar panels to generate electricity during the day to power the streetlights at night, making them very environmentally friendly.

[0003] However, these solar streetlights have limitations in use. During long-term outdoor use, dust easily accumulates on the surface of the solar panels, affecting their light-gathering effect. Due to the height of the streetlight poles, the distance between the lamp body and the supporting solar panels and the ground increases, making it more difficult to clean and maintain the solar panels. In addition, the existing photovoltaic panels installed on solar streetlights lack protection against severe weather conditions such as acid rain, hail, or snow, making them susceptible to damage and resulting in economic losses. Summary of the Invention

[0004] The purpose of this invention is to provide a fixed and rotating device for solar modules to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fixed rotating device for a solar panel includes a self-cleaning component. The self-cleaning component includes an L-shaped groove, with a rotating roller rotatably mounted at the corner of the L-shaped groove. The rotating rollers are driven by a synchronous belt externally sleeved on one side. A gravity brush is externally engaged with one side of the synchronous belt, and the bottom plane of the gravity brush is provided with a water spray hole and a rubber scraper. A water tank is embedded in the bottom of the L-shaped groove, and a piston plate is slidably mounted inside the water tank. The piston plate is engaged with the synchronous belt on the same side as the gravity brush. One end of the water tank is provided with a water inlet, and the other end is connected to the gravity brush through a corrugated hose.

[0007] Furthermore, the L-shaped groove is embedded inside the double-sided mounting plate, and the ends of the double-sided mounting plate are fixed with crescent teeth, and the two sides of the double-sided mounting plate are coaxially fixed with trunnions.

[0008] Furthermore, an LED street light is provided on one side of the double-sided mounting plate, and a photovoltaic panel is provided on the other side of the double-sided mounting plate. The end plane of the photovoltaic panel is in contact with the gravity brush. A baffle is fixedly installed at the bottom of the photovoltaic panel, and a bowl-shaped water collection port facing the water inlet of the water tank is provided at the end of the inclined surface of the baffle.

[0009] Furthermore, a battery is provided on the side of the photovoltaic panel, and a controller is connected to the battery. After the photovoltaic panel converts light energy into electrical energy, the controller stores the energy inside the battery, and the battery supplies power to the LED street light through wires.

[0010] Furthermore, the double-sided mounting plate is rotatably mounted inside the recess of the flip bracket, and a motor is bolted to the side end of the flip bracket, and the motor is connected to the trunnion on the side end of the double-sided mounting plate via a coupling.

[0011] Furthermore, a connecting flange is fixedly installed at the bottom center of the flip bracket, and the connecting flange is bolted to the lamp post of the new energy street light. A back plate is fixedly installed on the back of the flip bracket, and a drainage hole is opened at the bottom of the arc surface of the back plate.

[0012] Furthermore, a housing is fixedly installed at the top of the arc surface of the back plate, and a sensor module is fixedly installed on the top plane of the housing.

[0013] Furthermore, a shaft bracket extends from the bottom plane of the housing, and a gear is rotatably mounted inside the shaft bracket, and the gear meshes with the crescent teeth at the end of the double-sided mounting plate.

[0014] Furthermore, one end of the gear is coaxially connected to a drive wheel, and a belt is fitted around the drive wheel, with the belt passing through a groove on the housing to enter the interior.

[0015] Furthermore, the interior of the housing is equipped with a linkage telescopic assembly, which includes a protective cover, a guide rail, a reflector, a rack, a second gear, and a driven wheel. The protective cover slides with the guide rail on the inner wall of the housing, and the reflector is attached to the inner wall of the protective cover. A rack is fixedly installed on the side wall of the protective cover along the length direction, and the rack meshes with the second gear for transmission. The driven wheel is coaxially connected to the end of the second gear, and the driven wheel is connected to the drive wheel for rotational transmission via a belt. Beneficial effects

[0016] This invention enables rainwater to flow over the surface of a photovoltaic panel and, guided by the bottom baffle, into a water tank through a bowl-shaped inlet for collection. As day and night alternate, the double-sided mounting plate is rotated by a motor, allowing the gravity brush to self-clean dust and impurities on the photovoltaic panel surface during the rotation process, under the combined action of the bottom rubber scraper and water spray holes. In this self-cleaning component, the cleaning water comes from natural rainwater, and the movement and resetting of the gravity brush rely solely on gravity. It can automatically achieve self-cleaning of the photovoltaic panel surface by rotating the double-sided mounting plate during the day and night alternation.

[0017] This application utilizes a double-sided mounting plate, with a photovoltaic panel installed on one side and an LED street light installed on the other. During the day when sunlight conditions are good, the side of the double-sided mounting plate with the photovoltaic panel faces the sunlight. The photovoltaic panel converts light energy into electrical energy, which is then stored in a battery via a controller. When lighting is needed at night, a motor drives the double-sided mounting plate to flip and fix it within a rotating bracket, so that the other side of the double-sided mounting plate with the LED street light faces the ground. The battery supplies power to the LED street light through wires, using the electrical energy stored in the battery during the day from the photovoltaic panel to illuminate the LED street light, greatly simplifying the structure and reducing the installation volume.

[0018] 3. When the double-sided mounting plate in this invention flips during the day-night cycle, the crescent-shaped teeth at the end of the double-sided mounting plate mesh with the gear on one side of the shaft frame and drive the transmission. This causes the drive wheel on the other side of the shaft frame to rotate through a belt towards the driven wheel inside the housing. The driven wheel then drives the rack on the side of the protective cover through a gear coaxial with it, causing the protective cover to extend and retract in conjunction with the housing. This further strengthens the physical protection of the photovoltaic panels under severe weather conditions. Moreover, the extension and retraction of the protective cover is linked with the flipping and resetting action of the double-sided mounting plate driven by the motor, eliminating the need for an additional power mechanism for the linkage extension and retraction component, thus making the linkage between the various mechanisms within the device stronger.

[0027] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0028] Please see Figures 1 to 7 This invention provides a fixed and rotating device for solar modules, including a self-cleaning component 1. The self-cleaning component 1 includes an L-shaped groove 101. A rotating roller 102 is rotatably installed at the corner of the L-shaped groove 101, and the rotating rollers 102 are rotated and driven by an externally sleeved synchronous belt 103. A gravity brush 104 is snapped onto the outside of one side of the synchronous belt 103, and the bottom plane of the gravity brush 104 is provided with a water spray hole and a rubber scraper. A water tank 105 is embedded in the bottom of the L-shaped groove 101, and a piston plate 106 is slidably installed inside the water tank 105. The piston plate 106 is snapped onto the synchronous belt 103 on the same side as the gravity brush 104. One end of the water tank 105 is provided with a water inlet, and the other end is connected to the gravity brush 104 through a corrugated hose 107.

[0029] The specific operation is as follows: On rainy days, rainwater flows over the surface of the photovoltaic panel 6 and, guided by the bottom baffle 7, flows into the water tank 105 through the bowl-shaped water inlet 8 for collection. When day and night alternate, the double-sided mounting plate 2 is rotated by the motor 12. At this time, the gravity brush 104 slides on the surface of the photovoltaic panel 6 under the action of gravity, and then drives the rotating roller 102 between the three corners of the L-shaped groove 101 to rotate through the synchronous belt 103, so that the piston plate 106 connected to the synchronous belt 103 on the same side as the gravity brush 104 slides in the water tank 105. The water stored in the water tank 105 is pumped to the gravity brush 104 by the piston plate 106 through the corrugated hose 107. The gravity brush 104 can achieve self-cleaning of dust and impurities on the surface of the photovoltaic panel 6 during the flipping process under the dual action of the bottom rubber scraper and the water spray hole. The cleaning water in the self-cleaning component 1 of this application comes from natural rainwater. The movement and reset of the gravity brush 104 are achieved by gravity alone. It can automatically achieve self-cleaning of the surface of the photovoltaic panel 6 by flipping during the day and night change of the double-sided mounting plate 2.

[0030] Please see Figures 5 to 6 An L-shaped groove 101 is embedded inside the double-sided mounting plate 2, and a crescent tooth 3 is fixed at the end of the double-sided mounting plate 2. A trunnion 4 is coaxially fixed on both sides of the double-sided mounting plate 2. An LED street light 5 is installed on one side of the double-sided mounting plate 2, and a photovoltaic panel 6 is installed on the other side of the double-sided mounting plate 2. The end plane of the photovoltaic panel 6 is in contact with the gravity brush 104. A baffle 7 is fixedly installed at the bottom of the photovoltaic panel 6, and a bowl-shaped water inlet 8 facing the water inlet hole of the water tank 105 is provided at the end of the inclined surface of the baffle 7. A storage battery 9 is installed on the side of the photovoltaic panel 6, and a controller 10 is connected to the external of the storage battery 9. After the photovoltaic panel 6 converts light energy into electrical energy, it stores the energy in the storage battery 9 through the controller 10. The storage battery 9 supplies power to the LED street light 5 through wires.

[0031] The double-sided mounting plate 2 is rotatably mounted inside the recess of the flip bracket 11, and the side end of the flip bracket 11 is bolted with a motor 12. The motor 12 is connected to the trunnion 4 on the side end of the double-sided mounting plate 2 via a coupling. The bottom middle of the flip bracket 11 is fixedly mounted with a connecting flange 13, and the connecting flange 13 is bolted to the lamp post of the new energy street light. The back plate 14 is fixedly mounted on the back of the flip bracket 11, and the bottom end of the arc surface of the back plate 14 is provided with a drainage hole 15.

[0032] A photovoltaic panel 6 is installed on one side of the double-sided mounting plate 2, and an LED street light 5 is installed on the other side. When the daytime lighting conditions are good, the plane of the double-sided mounting plate 2 with the photovoltaic panel 6 faces the sunlight. The photovoltaic panel 6 converts the light energy into electrical energy, which is then stored in the battery 9 by the controller 10. When lighting is needed at night, the double-sided mounting plate 2 is rotated and fixed in the flip bracket 11 by the motor 12, so that the plane of the double-sided mounting plate 2 with the LED street light 5 faces the ground. The battery 9 supplies power to the LED street light 5 through wires. The electrical energy stored in the battery 9 by the photovoltaic panel 6 during the day is used to emit light from the LED street light 5, which greatly simplifies the structure and reduces the installation volume.

[0033] Please see Figures 3 to 4 A housing 16 is fixedly mounted on the top of the arc surface of the back panel 14, and a sensor module 17 is fixedly mounted on the top plane of the housing 16. A shaft bracket 18 extends from the bottom plane of the housing 16, and a gear 19 is rotatably mounted inside the shaft bracket 18. The gear 19 meshes with the crescent teeth 3 at the end of the double-sided mounting plate 2. A drive wheel 20 is coaxially connected to the end of the gear 19, and a belt 21 is sleeved on the outside of the drive wheel 20. The belt 21 enters the housing 16 through a groove. A linkage telescopic assembly 22 is provided inside the housing 16. The linkage telescopic assembly 22 includes a protective cover. 2201, guide rail 2202, reflector 2203, rack 2204, gear 2205, and driven wheel 2206. The protective cover 2201 slides with the guide bar on the inner wall of the housing 16 via the guide rail 2202, and the reflector 2203 is attached to the inner wall of the protective cover 2201. The rack 2204 is fixedly installed on the side wall of the protective cover 2201 along the length direction, and the rack 2204 meshes with gear 2205 for transmission. The driven wheel 2206 is coaxially connected to the end of gear 2205, and the driven wheel 2206 is connected to the drive wheel 20 for rotational transmission via belt 21.

[0034] Understandably, through the above-mentioned setup, when the double-sided mounting plate 2 flips during the day-night cycle, the crescent-shaped teeth 3 at the end of the double-sided mounting plate 2 mesh with the gear 19 on one side of the shaft frame 18, causing the drive wheel 20 on the other side of the shaft frame 18 to rotate through the belt 21 to the driven wheel 2206 inside the housing 16. The driven wheel 2206 then drives the gear 2205 coaxial with it to the rack 2204 on the side of the protective cover 2201, causing the protective cover 2201 to extend and retract in conjunction within the housing 16. In other words, during the day, the side of the double-sided mounting plate 2 with the photovoltaic panel 6 faces the sunlight, and the protective cover 2201 is stored inside the housing 16 to avoid blocking the sunlight and affecting the power generation efficiency of the photovoltaic panel 6. At night, the double-sided mounting plate 2 flips under the action of the motor 12. The rotating bracket 11 is flipped and fixed inside, so that the side of the double-sided mounting plate 2 with the LED street light 5 faces the ground. At this time, the protective cover 2201 extends out from inside the box 16. The reflector 2203 attached to the inner wall of the protective cover 2201 improves the utilization rate of light and reduces light waste to improve the lighting effect. When the sensor module 17 on the top of the box 16 detects severe weather such as acid rain, hail or snow, it can also actively flip the double-sided mounting plate 2 to hide the photovoltaic panel 6 and shield it from the protective cover 2201, further strengthening the physical protection of the photovoltaic panel 6 under severe weather. Moreover, the extension and retraction of the protective cover 2201 is linked with the flipping and resetting action of the double-sided mounting plate 2 driven by the motor 12, without the need to add an additional power mechanism to the linkage extension component 22, making the linkage of various mechanisms in the device stronger.

[0035] In summary, this application has a photovoltaic panel 6 installed on one side of a double-sided mounting plate 2 and an LED street light 5 installed on the other side. When the daytime lighting conditions are good, the plane of the double-sided mounting plate 2 with the photovoltaic panel 6 faces the sunlight. The photovoltaic panel 6 converts light energy into electrical energy, which is then stored in the battery 9 by the controller 10. When lighting is needed at night, the double-sided mounting plate 2 is rotated and fixed in the flip bracket 11 by the motor 12, so that the plane of the double-sided mounting plate 2 with the LED street light 5 faces the ground. The battery 9 supplies power to the LED street light 5 through wires. The electrical energy stored in the battery 9 by the photovoltaic panel 6 during the day is used to emit light from the LED street light 5, which greatly simplifies the structure and reduces the installation volume.

[0036] On rainy days, rainwater flows over the surface of the photovoltaic panel 6 and, guided by the bottom baffle 7, flows into the water tank 105 through the bowl-shaped water inlet 8 for collection. During the day-night cycle, the double-sided mounting plate 2 is rotated by the motor 12. At this time, the gravity brush 104 slides on the surface of the photovoltaic panel 6 under gravity, which in turn drives the rotating rollers 102 at the three corners of the L-shaped groove 101 to rotate via the synchronous belt 103. This causes the piston plate 106, connected to the synchronous belt 103 on the same side as the gravity brush 104, to slide inside the water tank 105, thus... The water stored in the water tank 105 is pumped to the gravity brush 104 by the piston plate 106 through the corrugated hose 107. The gravity brush 104 can achieve self-cleaning of dust and impurities on the surface of the photovoltaic panel 6 during the flipping process under the dual action of the bottom rubber scraper and the water spray hole. The cleaning water in the self-cleaning component 1 of this application comes from natural rainwater. The movement and reset of the gravity brush 104 are achieved by gravity alone. It can automatically achieve self-cleaning of the surface of the photovoltaic panel 6 by flipping during the day and night change of the double-sided mounting plate 2.

[0037] When the double-sided mounting plate 2 flips during the day-night cycle, the crescent-shaped teeth 3 at the end of the double-sided mounting plate 2 mesh with the gear 19 on one side of the shaft bracket 18 and drive the transmission. This causes the drive wheel 20 on the other side of the shaft bracket 18 to rotate through the belt 21 to the driven wheel 2206 inside the housing 16. The driven wheel 2206 drives the rack 2204 on the side of the protective cover 2201 through the coaxial gear 2205. This causes the protective cover 2201 to extend and retract in conjunction with the housing 16. In other words, during the day, the side of the double-sided mounting plate 2 with the photovoltaic panel 6 faces the sunlight. At this time, the protective cover 2201 is stored inside the housing 16 to avoid blocking the sunlight and affecting the power generation efficiency of the photovoltaic panel 6. At night, the double-sided mounting plate 2 flips inside the flipping bracket 11 under the action of the motor 12. The double-sided mounting plate 2 is fixed so that the side with the LED street light 5 faces the ground. At this time, the protective cover 2201 extends out from inside the box 16. The reflector 2203 attached to the inner wall of the protective cover 2201 improves the utilization rate of light and reduces light waste to enhance the lighting effect. When the sensor module 17 on the top of the box 16 detects severe weather such as acid rain, hail or snow, it can also actively flip the double-sided mounting plate 2 to hide the photovoltaic panel 6 and shield it from the protective cover 2201, further strengthening the physical protection of the photovoltaic panel 6 under severe weather. Moreover, the extension and retraction of the protective cover 2201 is linked with the flipping and resetting action of the double-sided mounting plate 2 driven by the motor 12, eliminating the need to add an additional power mechanism to the linkage extension component 22, making the linkage of various mechanisms in the device stronger.
