[0054] Photovoltaic panels use photovoltaic power generation technology to convert light energy into electrical energy. Photovoltaic panels are composed of multiple solar cells, and these cells are connected in series and then encapsulated and protected to form a large-area solar cell module.

[0055] Existing fixed photovoltaic panels are fixed on brackets at a certain angle to the ground. This installation method makes the photovoltaic panels maintain a fixed orientation and angle for a long time and does not move with the change of the sun's position. When the sun's position changes at different times, the angle of the light incident on the photovoltaic panels changes accordingly, resulting in the ineffective utilization of light energy.

[0056] Therefore, the problem that needs to be urgently solved in the present application is that fixed photovoltaic panels cannot effectively utilize light energy when the sun's position changes.

[0057] Based on this, an auxiliary device for photovoltaic power generation and a photovoltaic power generation device provided by an embodiment of the present application. The auxiliary device for photovoltaic power generation includes: a photosensitive angle adjustment system 100, a linkage system 200, a support assembly 300, and at least one light storage and reflection plate 400. The photosensitive angle adjustment system 100 includes: a photosensitive angle detector 110 and a motor 120 connected by communication. The photosensitive angle detector 110 is used to detect the incident angle of the light source and send an angle signal, and the motor 120 is used to perform operations according to the angle signal. The linkage system 200 includes: a motor drive wheel 210, a first linkage rack 220, a second linkage rack 230, and at least one follower wheel 240. The first linkage rack 220 connects the motor drive wheel 210 and the motor 120, the second linkage rack 230 connects the motor drive wheel 210 and the follower wheel 240, and the motor drive wheel 210 and the follower wheel 240 are respectively connected to a light storage and reflection plate 400. The support assembly 300 connects the light storage and reflection plate 400 and the photovoltaic panel 700. The first surface of the light storage and reflection plate 400 is a mirror surface, and the mirror surface is used to reflect light so that the light is perpendicularly irradiated onto the photovoltaic panel 700. It can be used in the technical field of photovoltaic power generation and aims to solve the above technical problems in the prior art.

[0058] Figure 1 It is a top view of the auxiliary device for photovoltaic power generation provided by an embodiment of the present application; Figure 2 It is a side view of the auxiliary device for photovoltaic power generation provided by an embodiment of the present application; Figure 3 It is a front view of the auxiliary device for photovoltaic power generation provided by an embodiment of the present application.

[0059] As Figure 1 、 Figure 2 and Figure 3 shown, an embodiment of the present application provides an auxiliary device for photovoltaic power generation, including: a photosensitive angle adjustment system 100, a linkage system 200, a support assembly 300, and at least one light storage and reflection plate 400.

[0060] The photosensitive angle adjustment system 100 includes: a photosensitive angle detector 110 and a motor 120 connected by communication. The photosensitive angle detector 110 is used to detect the incident angle of the light source and send an angle signal, and the motor 120 is used to perform operations according to the angle signal.

[0061] The linkage system 200 includes: a motor drive wheel 210, a first linkage rack 220, a second linkage rack 230, and at least one follower wheel 240. The first linkage rack 220 connects the motor drive wheel 210 and the motor 120, the second linkage rack 230 connects the motor drive wheel 210 and the follower wheel 240, and the motor drive wheel 210 and the follower wheel 240 are respectively connected to a light storage and reflection plate 400.

[0062] The support assembly 300 connects the light storage and reflection plate 400 and the photovoltaic panel 700.

[0063] The first surface of the light storage reflector 400 is a mirror surface, which is used to reflect light so that the light can vertically illuminate the photovoltaic panel 700.

[0064] Specifically, the photosensitive angle detector 110 detects the incident angle of the light source, converts the detected information into an angle signal and sends it to the motor 120. The angle signal includes information indicating the rotation of the light storage reflector 400.

[0065] Motor 120 includes a primary drive wheel. Based on the angle signal, the primary drive wheel drives motor drive wheel 210 via first linkage rack 220, which in turn rotates light storage reflector plate 400, which is connected to motor drive wheel 210. The mirrored surface of light storage reflector plate 400 reflects light, causing it to strike photovoltaic panel 700 perpendicularly, thereby improving light energy utilization efficiency. Simultaneously, motor drive wheel 210 drives follower wheel 240 via second linkage rack 230, causing light storage reflector plate 400, which is connected to follower wheel 240, to rotate, thereby ensuring that light strikes photovoltaic panel 700 perpendicularly.

[0066] Figure 4 A schematic diagram of a working mode 1 of the photovoltaic power generation auxiliary device provided in an embodiment of the present application; Figure 5 Schematic diagram of working mode 2 of the photovoltaic power generation auxiliary device provided in an embodiment of the present application.

[0067] like Figure 4 As shown, the line segments with arrows represent the light and the incident direction. When the light is incident vertically on the photovoltaic panel 700, the light storage reflector 400 rotates to be vertical to the photovoltaic panel 700 so that the light is incident vertically on the photovoltaic panel 700.

[0068] like Figure 5 As shown, the line segment with an arrow represents the light and the incident direction. When the light is not incident vertically on the photovoltaic panel 700, the light storage reflector 400 rotates and adjusts the mirror reflection angle of the light storage reflector 400 so that the light is incident vertically on the photovoltaic panel 700, reducing the energy loss caused by the oblique irradiation of the light, allowing the photovoltaic panel 700 to achieve a good light receiving state and improve the power generation efficiency.

[0069] For example, there may be one or more follower wheels 240 and one or more light storage reflective plates 400, and the number can be adjusted according to the size of the photovoltaic panel 700, thereby making the photovoltaic power generation auxiliary device more applicable.

[0070] For example, the bracket assembly 300 can connect the light storage reflective plate 400 and the photovoltaic panel 700 by screw connection, welding, clamping, etc., to ensure the stability of the position of the light storage reflective plate 400.

[0071] In a possible design, a solar cell is provided on the second surface of the light storage reflector 400. When the photovoltaic panel 700 is not generating electricity, the solar cell is used to convert light energy into electrical energy and store it.

[0072] Specifically, a solar cell is a device that directly converts light energy into electrical energy through the photovoltaic effect or the photochemical effect.

[0073] Figure 6 This is a schematic diagram of working mode three of the photovoltaic power generation auxiliary device provided by the embodiment of the present application. As Figure 6 shown, the arrowed line segments represent light rays and the incident directions. Due to situations such as the power grid being unable to absorb the electrical energy generated by the photovoltaic power generation device, when the photovoltaic panel 700 is not generating electricity, the second surface of the light storage reflector 400 provided with the solar cell faces the light rays, and the light rays charge the solar cell, storing the light energy that was originally "abandoned".

[0074] In a possible design, a light-emitting diode is also provided on the second surface of the light storage reflector 400; the solar cells and the light-emitting diodes are arranged in a cross pattern, and the solar cells and the light-emitting diodes are connected by wires. The solar cells are used to provide electrical energy for the light-emitting diodes, so as to facilitate the light-emitting diodes to irradiate the photovoltaic panel 700 and provide light energy for the photovoltaic panel 700.

[0075] Specifically, a light-emitting diode is a light-emitting device that can convert electrical energy into light energy.

[0076] Figure 7 This is a schematic diagram of working mode four of the photovoltaic power generation auxiliary device provided by the embodiment of the present application. As Figure 7 shown, the arrowed line segments represent light rays and the incident directions. When there is no light at night or the light is very poor on cloudy days, using working mode three or when the photovoltaic panel 700 is working normally, the electrical energy converted and stored by the solar cells from the remaining light rays is used to provide electrical energy for the light-emitting diodes, causing the light-emitting diodes to emit light and thus continuously providing light energy for the photovoltaic panel 700, further improving the photovoltaic power generation amount and its adjustability.

[0077] In a possible design, it further includes: a connecting shaft 500.

[0078] The light storage reflector 400 is provided with a horizontal through hole, and the connecting shaft 500 passes through the through hole, so as to facilitate the fixed connection of the light storage reflector 400 to the connecting shaft 500.

[0079] Both ends of the connecting shaft 500 are fixedly connected to the motor drive wheel 210 and the follower wheel 240 respectively.

[0080] Specifically, the connecting shaft 500 penetrates through the through hole, and the length of the connecting shaft 500 exceeds the size of the optical storage reflector 400, so as to facilitate the fixed connection of both ends of the connecting shaft 500 to the motor drive wheel 210 and the follower wheel 240 respectively. Bracket assemblies 300 and follower wheels 240 are installed at both ends of the optical storage reflector 400, and the follower wheels 240 are connected by a rack, further improving the stability of the position of the optical storage reflector 400 and ensuring the synchronization of the rotation of the optical storage reflector 400, avoiding the situation where one end of the optical storage reflector 400 fails to rotate due to linkage failure.

[0081] Exemplarily, the connecting shaft 500 penetrates through the through hole, and the optical storage reflector 400 can be fixedly connected to the connecting shaft 500 by screwing, welding, etc. The embodiments of the present application do not limit this connection method.

[0084] Exemplarily, both the first bracket 310 and the second bracket 320 can be one or more, and the number can be adjusted according to the size of the photovoltaic panel 700 to enhance the applicability of the photovoltaic power generation auxiliary device.

[0085] Exemplarily, the first bracket 310 is rotatably connected to the connecting shaft 500, and specifically, the rotatable connection can be achieved through connection methods such as bearing connection and hinge connection. The embodiments of the present application do not limit this connection method.

[0086] Exemplarily, the first bracket 310 and the second bracket 320 are fixedly connected. In one example, the fixed connection can be achieved by screwing, or other connection methods can also be used to achieve the fixed connection. The embodiments of the present application do not limit this connection method.

[0087] In a possible design, the first bracket 310 and the second bracket 320 are fixedly connected by bolts in a one-to-one manner.

[0088] Specifically, the two second brackets 320 can be spliced and detachably connected. In one example, the splicing buckle can be used to achieve the splicing and disassembly of the second bracket, so as to be applicable to photovoltaic panels 700 of different sizes.

[0089] Each second bracket 320 and the corresponding first bracket 310 are fixedly connected by bolts, which is convenient for disassembly.

[0090] In a possible design, the photovoltaic panel 700 is embedded in the second bracket 320, and the second bracket 320 and the photovoltaic panel 700 are fixedly connected by bolts.

[0091] Specifically, the second brackets 320 located at both side edges may be provided with grooves for the photovoltaic panel 700 to be embedded therein, and the second brackets 320 and the photovoltaic panel 700 are fixedly connected by bolts.

[0092] Exemplarily, bolts penetrate through the second bracket 320 and the photovoltaic panel 700 to fixedly connect the second bracket 320 and the photovoltaic panel 700.

[0093] In a possible design, among the motor drive wheel 210 and at least one light storage and reflection plate 400, the light storage and reflection plate 400 located at one side edge is connected.

[0094] In a possible design, it further includes: a protective housing 600; the protective housing 600 is fixedly connected to the second bracket 320 by bolts, and the photosensitive angle adjustment system 100 is located inside the protective housing 600.

[0095] Specifically, the cross-section of the second brackets 320 located at both side edges may be provided with protrusions for the protective housing 600 to be fixedly connected to the second bracket 320 by bolts.

[0096] Exemplarily, bolts horizontally penetrate through the protrusions of the second bracket 320 and the protective housing 600 to fixedly connect the protective housing 600 to the second bracket 320 by bolts.

[0097] A photovoltaic power generation auxiliary device provided by an embodiment of the present application includes: a photosensitive angle adjustment system 100, a linkage system 200, a bracket assembly 300, and at least one light storage and reflection plate 400; the photosensitive angle adjustment system 100 includes: a photosensitive angle detector 110 and a motor 120 connected in communication, the photosensitive angle detector 110 is used to detect the incident angle of the light source and send an angle signal, and the motor 120 is used to perform operations according to the angle signal; the linkage system 200 includes: a motor drive wheel 210, a first linkage rack 220, a second linkage rack 230, and at least one follower wheel 240, the first linkage rack 220 connects the motor drive wheel 210 and the motor 120, the second linkage rack 230 connects the motor drive wheel 210 and the follower wheel 240, and the motor drive wheel 210 and the follower wheel 240 are respectively connected to a light storage and reflection plate 400; the bracket assembly 300 connects the light storage and reflection plate 400 and the photovoltaic panel 700; the first surface of the light storage and reflection plate 400 is a mirror surface, and the mirror surface is used to reflect light so that the light is perpendicularly incident on the photovoltaic panel 700. The achieved technical effects are as follows:

[0098] The photosensitive angle detector 110 detects the incident angle of the light source and sends an angle signal, so that the motor 120 drives the optical storage reflector 400 to rotate according to the angle signal. The specularly reflected light of the optical storage reflector 400 ensures that the light is perpendicularly irradiated on the photovoltaic panel 700, solving the problem that the fixed photovoltaic panel 700 cannot effectively utilize solar energy when the sun's position changes.

[0099] The solar cells arranged on the second surface of the optical storage reflector 400 store the solar energy wasted by the phenomena of "power rationing" and "light abandonment", and provide electrical energy for the light-emitting diodes to irradiate the photovoltaic panel 700, thereby further increasing the power generation.

[0100] Meanwhile, the electrical energy converted and stored from the light surplus by the solar cells arranged on the second surface of the optical storage reflector 400 provides electrical energy for the light-emitting diodes, thereby continuously providing solar energy for the photovoltaic panel 700, enhancing the adjustable performance of photovoltaic power generation. Under appropriate circumstances, it can participate in the peak regulation and frequency modulation of the system, making photovoltaic power generation more flexible.
