[0030] The optional embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] In a preferred embodiment 1 of the present invention, a photovoltaic rotating device is provided. Specifically, Figure 1 An optional structural schematic diagram of the photovoltaic rotating device is shown, such as Figure 1 As shown, the photovoltaic rotating device comprises:

[0033] The photovoltaic plane bracket 1 is used to support the photovoltaic panel. The photovoltaic panel is arranged on the photovoltaic plane bracket 1. The photovoltaic panel is used to receive sunlight and convert solar energy into electrical energy.

[0034] The bracket rotating device is connected to the photovoltaic plane bracket and is used to rotate the photovoltaic plane bracket according to the direction of the sunlight so that the photovoltaic panel is set perpendicular to the sunlight. The bracket rotating device includes a sliding rod shaft and a rotating rod. The sliding rod shaft is connected to the photovoltaic plane bracket and is used to support the photovoltaic plane bracket. One end of the rotating rod is connected to the photovoltaic plane bracket and the other end is connected to the sliding rod shaft. It is used to rotate the photovoltaic plane bracket according to the direction of the sunlight so that the photovoltaic panel is set perpendicular to the sunlight. Figure 1 As shown in the figure, the sun rises in the east and sets in the west, and is in different positions at different times of the day, so the angle between it and the photovoltaic panel is also different. The support rotating device in the present invention follows the sunlight in the east-west direction, that is, Figure 1 It rotates on the plane formed by the XY axes of the center view, keeping it perpendicular to the sunlight in real time, thereby maximizing the absorption and utilization of solar energy.

[0035] In the above embodiment, a photovoltaic rotating device capable of rotating in accordance with sunlight is provided, comprising a photovoltaic plane bracket for supporting a photovoltaic panel, and a bracket rotating device for rotating the photovoltaic plane bracket according to the direction of sunlight, so that the photovoltaic panel is arranged perpendicular to the sunlight. Through the above photovoltaic rotating device, the angle of the sun is automatically tracked, so that the photovoltaic panel and the sunlight are at a 90° direct angle, reducing the reduction in the power generation efficiency of the photovoltaic panel due to fixed angle restrictions and shading, maximizing the absorption of solar radiation, increasing the power generation of the photovoltaic panel, and improving the power generation efficiency of the photovoltaic system, thereby reducing the layout of the photovoltaic panels and reducing the cost of the photovoltaic system.

[0036] like Figure 1As shown, the support rotation device includes: a sliding rod shaft 2, the top of the sliding rod shaft 2 is slidably connected to the bottom of the photovoltaic plane support 1, and the sliding rod shaft 2 slides along the east-west direction at the bottom of the photovoltaic plane support 1; when necessary, the sliding rod shaft 2 can be telescopically adjusted, that is, the length is adjustable to ensure that the photovoltaic panel is located at a required angle. The rotating rod includes a first rotating rod 3 and a second rotating rod 4, the first end of the first rotating rod 3 is fixedly connected to the first end of the photovoltaic plane support 1, the second end of the first rotating rod 3 is slidably connected to the first side of the sliding rod shaft 2, the first end of the second rotating rod 4 is fixedly connected to the second end of the photovoltaic plane support 1, and the second end of the second rotating rod 4 is slidably connected to the second side of the sliding rod shaft 2; wherein the first end of the photovoltaic plane support 1 is located on the east side of the photovoltaic plane support 1, the second end of the photovoltaic plane support 1 is located on the west side of the photovoltaic plane support 1, the first side of the sliding rod shaft 2 is located on the east side of the sliding rod shaft 2, and the second side of the sliding rod shaft 2 is located on the west side of the sliding rod shaft 2. Based on the above bracket rotation device, the first rotating rod 3 and the second rotating rod 4 are slidably connected to the sliding rod shaft 2, and the sliding rod shaft 2 is slidably connected to the bottom of the photovoltaic plane bracket 1, so that the photovoltaic plane bracket 1 has different tilt angles through the different positions of the sliding rod shaft 2, the first rotating rod 3 and the second rotating rod 4, so that the photovoltaic panel can be rotated on the photovoltaic plane bracket 1 to follow the direction of sunlight. And the combination of the above sliding rod shaft 2, the first rotating rod 3 and the second rotating rod 4 can make the photovoltaic plane bracket 1 rotate stably to different angles, with high stability and reliability.

[0037] Figure 2 A schematic diagram of the support rotating device is further shown in FIG. Figure 2 As shown, the bracket rotating device also includes: a first slide groove 6, located on the first side of the sliding rod shaft 2, the second end of the first rotating rod 3 is located in the first slide groove 6, and slides up and down along the first slide groove 6; a second slide groove 7, located on the second side of the sliding rod shaft 2, the second end of the second rotating rod 4 is located in the second slide groove 7, and slides up and down along the second slide groove 7; in addition, in order to drive the rotating rod to move, a first motor is also provided, located in the first slide groove 6, and used to drive the first rotating rod 3 to slide up and down along the first slide groove 6; a second motor is located in the second slide groove 7, and used to drive the second rotating rod 4 to slide up and down along the second slide groove 7. Figure 2 As shown, the first slide groove 6 is located on the east side of the sliding rod shaft 2, and the second slide groove 7 is located on the west side of the sliding rod shaft 2. The sliding rod shaft 2 can be in the form of a rectangular parallelepiped to make the slide groove more stable. Since the structure in the present invention is a triangular structure, the present invention has a certain stability. In order to further improve the stability of the structure, different slots can be set in the slide groove, and the sliding rod shaft 2 can be stuck in the slot when it does not need to move, so as to further improve the stability.

[0038] In addition, the bracket rotation device also includes: a photosensitive sensor, located on the photovoltaic panel, for detecting the direction of sunlight; by detecting the direction of sunlight, the angle of the photovoltaic panel is adjusted to control the precise positioning of the rotation direction of the photovoltaic panel so that it can always face the sun, thereby maximizing the absorption of solar radiation and improving the power generation efficiency of the photovoltaic system.

[0039] In addition, if Figure 1 As shown, the device further includes a base 5, and the bottom of the sliding rod shaft 2 is located in the base 5. The photovoltaic rotating device is supported by the base 5, so that the photovoltaic rotating device can operate stably. At the same time, by accurately responding to the position of the sun, the tracking accuracy and stability of the photovoltaic power generation system are comprehensively improved.

[0040] The photovoltaic rotating device in the present invention can follow the rising and setting of the sun, and absorb solar energy to the maximum extent by tracking the sun's position in real time, thereby increasing power generation. Compared with statically fixed photovoltaic panels, it can increase power generation by about 10%-30%, thereby improving the power generation efficiency of the entire photovoltaic panel power generation system.

[0041] Example 2

[0042] In a preferred embodiment 2 of the present invention, a photovoltaic rotating device control method is provided, which is applied to the photovoltaic rotating device in the above embodiment 1. Specifically, Figure 3 An optional flow chart of the method is shown as follows: Figure 3 As shown, the method includes the following steps S302-S306:

[0043] S302: Acquire the direction of sunlight, and determine the setting angle of the photovoltaic panel according to the direction of sunlight;

[0044] S304: Determine a displacement parameter of the support rotating device according to the setting angle of the photovoltaic panel;

[0045] S306: Controlling the operation of the support rotating device according to the displacement parameters.

[0046] In the above embodiment, a photovoltaic rotating device capable of rotating in accordance with sunlight is provided, comprising a photovoltaic plane bracket for supporting a photovoltaic panel, and a bracket rotating device for rotating the photovoltaic plane bracket according to the direction of sunlight, so that the photovoltaic panel is arranged perpendicular to the sunlight. Through the above photovoltaic rotating device, the angle of the sun is automatically tracked, so that the photovoltaic panel and the sunlight are at a 90° direct angle, reducing the reduction in the power generation efficiency of the photovoltaic panel due to fixed angle restrictions and shading, maximizing the absorption of solar radiation, increasing the power generation of the photovoltaic panel, and improving the power generation efficiency of the photovoltaic system, thereby reducing the layout of the photovoltaic panels and reducing the cost of the photovoltaic system.

[0047] In the present invention, the photovoltaic panel is mainly adjusted to rotate in the east-west direction, that is, the setting angle of the photovoltaic panel is the east-west angle; the north-south direction is set perpendicular to the sunlight before the adjustment scheme, that is, before obtaining the direction of the sunlight, it also includes: obtaining the longitude and latitude of the area where the photovoltaic panel is located; calculating the north-south angle of the photovoltaic panel according to the longitude and latitude, and adjusting the photovoltaic panel to the north-south angle. The sun moves slowly in the north-south direction, so the north-south angle changes less. After determining the south direction angle based on longitude and latitude, only the east-west angle needs to be adjusted during daily use, so that the utilization rate of sunlight is optimized.

[0048] Furthermore, obtaining the direction of the sunlight includes: obtaining the longitude and latitude of the area where the photovoltaic panel is located; determining the movement speed of the sunlight according to the longitude and latitude, setting the adjustment frequency of the photovoltaic rotating device according to the movement speed, and obtaining the direction of the sunlight according to the adjustment frequency. Since the sun is always moving from east to west, the adjustment frequency of the photovoltaic rotating device in the present method can be determined by determining the movement speed of the sunlight, so that the adjustment of the photovoltaic rotating device is synchronized with the movement of the sun, so that the adjustment frequency is not too low to reduce the utilization rate of solar energy, and the adjustment frequency is not too high to over-adjust or over-adjust.

[0049] In a preferred embodiment of the present invention, the displacement parameter of the support rotating device is determined according to the setting angle of the photovoltaic panel, including: calculating the distance between the second connection point of the first rotating rod 3 of the support rotating device and the top of the sliding rod shaft 2 and the distance between the second connection point of the second rotating rod 4 and the top of the sliding rod shaft 2 according to the setting angle of the photovoltaic panel; calculating the sliding distance of the second connection point of the first rotating rod 3 according to the distance between the second connection point of the first rotating rod 3 and the top of the sliding rod shaft 2 and the total height of the sliding rod shaft 2, and calculating the sliding distance of the second connection point of the second rotating rod 4 according to the distance between the second connection point of the second rotating rod 4 and the top of the sliding rod shaft 2 and the total height of the sliding rod shaft 2; wherein the initial position of the second connection point of the first rotating rod 3 is the bottom of the first sliding groove 6, and the initial position of the second connection point of the second rotating rod 4 is the bottom of the second sliding groove 7. That is, the first rotating rod 3 and the second rotating rod 4 move from bottom to top, and by calculating the distance between the second connection point of the first rotating rod 3 and the top of the sliding rod shaft 2, the moving distance of the first rotating rod 3 can be obtained by subtracting the distance between the second connection point of the first rotating rod 3 and the top of the sliding rod shaft 2 from the total height of the sliding rod shaft 2. Similarly, by calculating the distance between the second connection point of the second rotating rod 4 and the top of the sliding rod shaft 2, the moving distance of the second rotating rod 4 can be obtained by subtracting the distance between the second connection point of the second rotating rod 4 and the top of the sliding rod shaft 2 from the total height of the sliding rod shaft 2. Through the above steps, the moving distance of the rotating rod is accurately calculated, and the angle of the photovoltaic panel is accurately adjusted, so as to realize the vertical setting of the photovoltaic panel and the sunlight.

[0053] In the above embodiment, a photovoltaic rotating device capable of rotating in accordance with sunlight is provided, comprising a photovoltaic plane bracket for supporting a photovoltaic panel, and a bracket rotating device for rotating the photovoltaic plane bracket according to the direction of sunlight, so that the photovoltaic panel is arranged perpendicular to the sunlight. Through the above photovoltaic rotating device, the angle of the sun is automatically tracked, so that the photovoltaic panel and the sunlight are at a 90° direct angle, reducing the reduction in the power generation efficiency of the photovoltaic panel due to fixed angle restrictions and shading, maximizing the absorption of solar radiation, increasing the power generation of the photovoltaic panel, and improving the power generation efficiency of the photovoltaic system, thereby reducing the layout of the photovoltaic panels and reducing the cost of the photovoltaic system.

[0055] One end of the controller 401 is connected to the DC / DC converter 403, and the other end is connected to the power consumption side, and is used to supply power to the power consumption side according to the power supply parameters of the DC power supply. The electric energy absorbed by the photovoltaic panel is converted into a DC power supply through the DC / DC converter 403.
