[0002] In existing photovoltaic power generation systems, the efficiency of photovoltaic panels is affected by the angle and intensity of sunlight. Traditional fixed photovoltaic panels cannot adjust to changes in the sun's position, resulting in low light utilization during certain periods. To address this issue, light reflectors have been designed to help photovoltaic panels receive better light.

[0003] The prior art "Light reflecting device, photovoltaic module and photovoltaic system", with announcement number: CN220043362U, discloses a light reflecting device, which includes a reflector, an adjustment assembly and a fixing frame. The reflector has a first side and a second side arranged opposite to each other, the first side is located above the second side, the first side is rotatably connected to the fixing frame, the adjustment device is rotatably connected to the reflector, and the adjustment device is used to adjust the angle between the reflective surface of the reflector and the incident light. According to the light reflecting device of the utility model, the reflector is rotatably connected to the fixing frame, and the angle of the reflector can be adjusted according to the adjustment assembly. In this way, the angle of the rear reflector can be adjusted in time according to the angle and intensity of the incident light, so that more sunlight can be reflected to the back of the photovoltaic module in the front row, thereby improving the photoelectric conversion efficiency of the photovoltaic module.

[0004] The current light reflection device cannot adjust its position and angle by itself. It is affected by the photovoltaic panels and the adjustment is not flexible enough, resulting in low light utilization in certain time periods. Utility Model Content

[0005] The present invention aims to overcome the shortcomings of the prior art that the current light reflection device cannot adjust its position and angle by itself, is affected by the photovoltaic panels, and is not flexible enough in adjustment, resulting in low light utilization in certain time periods.

[0006] A high-efficiency photovoltaic light reflection device is proposed, comprising a photovoltaic panel and a mounting frame, and also comprising a tracking bracket, a first motor, a rotating bracket, a driving assembly, a reflecting plate assembly and a light sensor. The photovoltaic panel is connected to the mounting frame, the first motor is located at one end of the mounting frame and is arranged inside the mounting frame, the tracking bracket is arranged below the mounting frame and connected to the mounting frame, the rotating bracket is hinged above the mounting frame, and the first motor is connected to the rotating bracket, the driving assembly is connected inside the rotating bracket and is arranged on one side of the rotating bracket, the reflecting plate assembly is arranged above the photovoltaic panel and connected to the driving assembly, and the light sensor is arranged at the top of the reflecting plate assembly and connected to the first motor, the driving assembly and the reflecting plate assembly.

[0007] In the technical solution of the present utility model, the light sensor is arranged on the reflective plate. Therefore, after the rotating bracket and the reflective plate are opened, the light sensor on the reflective plate detects in real time the light intensity of the reflected light of the photovoltaic panel, and then the light sensor starts the first motor, the second motor and the third motor according to the light intensity to change the angle between the rotating bracket and the photovoltaic panel and the reflective plate and the photovoltaic panel, as well as the distance between the photovoltaic panel and the reflective plate, thereby changing the relative angle and relative distance between the reflective plate and the photovoltaic panel, thereby ensuring that the reflective plate can reflect the reflected light of the photovoltaic panel back to the photovoltaic panel at the optimal angle, so as to solve the shortcomings mentioned in the technical background that the current light reflection device cannot adjust the position and angle by itself, is affected by the photovoltaic panel, and is not flexible enough in adjustment, resulting in low light utilization in certain time periods.

[0008] Preferably, the rotating bracket is provided with a guide groove for guiding the reflector assembly. The guide groove can guide the sliding block and the reflector when the sliding block moves, thereby preventing the reflector from tilting.

[0009] The preferred technical solution of the present utility model is that the reflective plate assembly includes a reflective plate, a sliding block, a movable plate and a second motor. There are two groups of sliding blocks, both of which are slidably set on the rotating bracket and are respectively located on both sides of the reflective plate. The reflective plate is hinged on the sliding block, the movable plate is set inside the rotating bracket and connected to the driving assembly, and the sliding block is connected to the movable plate. The second motor is set inside the sliding block and connected to the reflective plate. When started, the second motor can drive the reflective plate to rotate, so as to change the angle between the reflective plate and the photovoltaic panel to ensure that the reflective plate can reflect the light reflected by the photovoltaic panel back to the photovoltaic panel again.

[0010] Preferably, the surface of the reflective plate is covered with a hydrophobic film. When raindrops fall on the reflective plate, they pass through the hydrophobic film and fall to the ground, preventing raindrops from forming drip marks on the reflective plate and reducing the reflection intensity of the reflective plate.

[0011] The preferred technical solution of the present utility model is that the driving assembly includes a third motor, a main gear, a sub-gear and a chain. The third motor is located at one end of the rotating bracket and is connected to the inside of the rotating bracket. The main gear is located on one side of the third motor and is connected to the output end of the main gear. The sub-gear is connected to the other end of the rotating bracket. The chain is sleeved on the main gear and the sub-gear, and the movable plate is connected to the chain. When the third motor drives the sub-gear to rotate through the main gear and the chain, the chain can drive the sliding block to move through the movable plate when it moves, thereby adjusting the distance between the reflector and the photovoltaic panel.

[0012] Preferably, the tracking bracket is a photovoltaic tracking bracket, which can adjust the position of the photovoltaic panel according to the position of the sun, thereby ensuring that the photovoltaic panel can be illuminated by the sun at an optimal angle.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] After the photovoltaic panel of the present invention is installed on the tracking bracket, the tracking bracket can automatically change the orientation of the photovoltaic panel and the angle between the photovoltaic panel and the ground according to the position of the sun, so as to improve the light utilization rate and power generation efficiency of the photovoltaic panel. When the photovoltaic panel is exposed to sunlight, the light sensor can automatically change the angle between the rotating bracket and the photovoltaic panel and between the reflecting plate and the photovoltaic panel according to the intensity of light reflected by the photovoltaic panel, so as to ensure that the sunlight reflected by the photovoltaic panel can be reflected back to the photovoltaic panel through the reflecting plate again, so as to improve the working efficiency of the reflecting plate.

DETAILED DESCRIPTION

[0022] The following is a combination of the appended examples of the present invention Figure 1-6 , the technical solutions in the embodiments of the present utility model are described in detail.

[0023] like Figure 1-5 As shown, a high-efficiency photovoltaic light reflection device includes a photovoltaic panel 1 and a mounting frame 2, and also includes a tracking bracket 3, a first motor 4, a rotating bracket 5, a driving assembly 6, a reflective plate assembly 7 and a light sensor 8. The tracking bracket 3 used is a photovoltaic tracking bracket. Therefore, after the photovoltaic panel 1 is connected to the top of the tracking bracket 3, the tracking bracket 3 can drive the photovoltaic panel 1 to rotate according to the rotation angle of the sun to ensure that the photovoltaic panel 1 can be exposed to the sun at the optimal angle. The photovoltaic tracking bracket is an existing technology and will not be explained here.

[0024] like Figure 1-5 As shown, the photovoltaic panel 1 is arranged above the mounting frame 2, and the photovoltaic panel 1 is connected to the mounting frame 2 by screws. The mounting frame 2 is arranged at the top of the tracking bracket 3, and the mounting frame 2 is connected to the movable end of the tracking bracket 3. Therefore, the tracking bracket 3 can use the mounting frame 2 to drive the photovoltaic panel 1 to rotate, so as to change the angle between the photovoltaic panel 1 and the ground, and the tracking bracket 3 can use the mounting bracket to drive the photovoltaic panel 1 to rotate according to the position of the sun, so as to change the direction of the photovoltaic panel 1.

[0025] like Figure 1-5 As shown, the rotating bracket 5 is arranged above the mounting frame 2, and one end of the rotating bracket 5 is hinged to the mounting frame 2, the first motor 4 is located at one end of the mounting frame 2 and is connected to the mounting frame 2 by screws, and the output end of the first motor 4 passes through the mounting frame 2 and is connected to the rotating bracket 5, so that the first motor 4 can drive the rotating bracket 5 to rotate when rotating, so as to change the angle between the rotating bracket 5 and the mounting frame 2.

[0026] like Figure 1-5 As shown, the driving component 6 is arranged in a preset groove on one side of the rotating bracket 5, and the driving component 6 is connected to the reflective plate component 7, so that the driving component 6 can drive the reflective plate 71 to move. The reflective plate component 7 is located above the photovoltaic panel 1 and is slidably arranged on the rotating bracket 5.

[0027] like Figure 1-5 As shown, the reflector assembly 7 includes a reflector 71, a sliding block 72, a movable plate 73 and a second motor 74. There are two groups of sliding blocks 72, both of which are slidably arranged on the rotating bracket 5. The rotating bracket 5 is provided with a guide groove 51 for guiding the sliding block 72. Therefore, the sliding block 72 can only slide along the length direction of the movable bracket. The two groups of sliding blocks 72 are respectively arranged on both sides of the reflector 71, and the reflector 71 is connected to the sliding block 72.

[0028] like Figure 1-5As shown, when the sliding block 72 slides on the rotating bracket 5, it will drive the reflective plate 71 to move synchronously. The moving plate 73 is arranged inside the rotating bracket 5, and the moving plate 73 is connected to the moving plate 73 of the driving component 6 by screws. The sliding block 72 located on one side of the driving component 6 is connected to the moving plate 73 by screws, so the chain 64 can drive the sliding block 72 to slide through the moving plate 73 when rotating.

[0029] like Figure 1-5 As shown, the second motor 74 is arranged inside the sliding block 72 on one side of the movable plate 73, and the second motor 74 is connected to the movable block by a screw, and the hinge shaft of the reflecting plate 71 is connected to the output end of the second motor 74, so the second motor 74 can drive the reflecting plate 71 to rotate, so as to change the angle between the reflecting plate 71 and the rotating bracket 5. The surface of the reflecting plate 71 is covered with a hydrophobic film, so even if raindrops fall on the surface of the reflecting plate 71, they will quickly drip to the ground due to the hydrophobic film, thereby avoiding affecting the surface clarity of the reflecting plate 71.

[0030] like Figure 1-5 As shown, the light sensor 8 is arranged at the top of the reflective plate 71 and is connected to the reflective plate 71 by screws, and the light sensor 8 is electrically connected to the first motor 4, the second motor 74 of the reflective plate assembly 7 and the third motor 61 of the drive assembly 6. Therefore, when the transmitting plate is opened, the light sensor 8 will detect the light intensity of the reflected light of the photovoltaic panel 1 in real time, and will change the angle of the reflective plate 71 through the first motor 4, the second motor 74 of the reflective plate assembly 7 and the third motor 61 of the drive assembly 6 according to the change of the light intensity of the reflected light of the photovoltaic panel 1.

[0031] The driving assembly 6 includes a third motor 61, a main gear 62, a sub-gear 63 and a chain 64. A groove is provided on one side of the rotating bracket 5. The third motor 61 is arranged in the groove on one side of the rotating bracket 5 and is located at one end of the groove. The third motor 61 is connected to the inside of the rotating bracket 5 by screws. The main gear 62 is vertically arranged inside the groove of the rotating bracket 5, and the main gear 62 is connected to the output shaft of the third motor 61 by a pin key.

[0032] like Figure 1-5 As shown, the third motor 61 can drive the main gear 62 to rotate, the sub-gear 63 is vertically arranged inside the groove of the rotating bracket 5 and is located at the other end of the groove, and the sub-gear 63 is rotatably connected to the rotating bracket 5, and the chain 64 is sleeved on the main gear 62 and the sub-gear 63. Therefore, when the second motor 74 drives the main gear 62 to rotate, the main gear 62 can drive the sub-gear 63 to rotate through the chain 64, and the movable plate 73 is connected to the chain 64.

[0033] like Figure 1-5As shown, when the second motor 74 drives the main gear 62 and the sub-gear 63 to rotate forward or reverse through the chain 64, the chain 64 can drive the sliding block 72 and the reflective plate 71 through the movable plate 73 to slide back and forth along the length direction of the rotating bracket 5. When the sliding block 72 drives the reflective plate to slide, the distance between the reflective plate 71 and the photovoltaic panel 1 can be changed.

[0034] like Figure 1-5 As shown, the light sensor 8 is electrically connected to the first motor 4, the second motor 74 of the drive assembly 6 and the third motor 61 of the reflector assembly 7. Therefore, when the first motor 4 opens the rotating bracket 5 and the third motor 61 rotates the reflector 71, the light sensor 8 will start to detect the intensity of the reflected light of the photovoltaic panel 1. As the angle between the sun and the photovoltaic panel 1 changes, the light sensor 8 can start the first motor 4 to adjust the angle between the rotating bracket 5 and the photovoltaic panel 1.

[0035] like Figure 1-5 As shown, it is used to prevent the sunlight shining on the photovoltaic panel 1 from being blocked by the reflector 71, and to adjust the distance between the photovoltaic panel 1 and the reflector 71 through the second motor 74 to ensure that the light reflected by the photovoltaic panel 1 can be reflected back to the photovoltaic panel 1 by the reflector 71 more quickly. At the same time, the light sensor 8 will start the third motor 61 to adjust the angle between the reflector 71 and the rotating bracket 5 to ensure that the reflective surface of the reflector 71 can reflect the light reflected by the photovoltaic panel 1 back to the photovoltaic panel 1 again, and ensure that the reflector 71 is at the optimal reflection angle.

[0036] The movement process of this embodiment: after the orientation of the photovoltaic panel 1 and the angle between the photovoltaic panel 1 and the ground are adjusted by the tracking bracket 3, the first motor 4 can be started. When the first motor 4 rotates forward, it can drive the rotating bracket 5 to rotate upward and open. At this time, the angle between the rotating bracket 5 and the photovoltaic panel 1 will change. After the rotating bracket 5 is rotated and opened to a suitable angle, the second motor 74 is started. When the second motor 74 rotates forward, the angle between the reflector 71 and the rotating bracket 5 will change.

[0037] Until the angle of the reflector 71 can reflect the light reflected by the photovoltaic panel 1 back onto the photovoltaic panel 1, the second motor 74 can stop rotating, and then the third motor 61 can be started and drive the main gear 62 and the sub-gear 63 to rotate through the chain 64. When the main gear 62 and the sub-gear 63 rotate, the height of the sliding block 72 and the reflector 71 can be adjusted through the chain 64. When the reflector 71 is turned on, the light sensor 8 will detect the intensity of the light reflected by the photovoltaic panel 1 in real time.

[0038] To ensure that the reflector 71 is at the optimal reflection angle, and as the position of the sun changes, the light sensor 8 will start the first motor 4, the second motor 74 and the third motor 61 to change the angle and distance between the reflector 71 and the photovoltaic panel 1 when it detects that the intensity of the reflected light from the photovoltaic panel 1 changes, ensuring that the reflector 71 is at the optimal reflection angle at all times.

[0039] The above embodiments are only for illustrating the technical idea of ​​the present invention and cannot be used to limit the protection scope of the present invention. Any changes made on the basis of the technical solution in accordance with the technical idea proposed by the present invention shall fall within the protection scope of the present invention.
