[0073] Based on this technical problem, the following embodiments are proposed.

[0074] Embodiment 1

[0075] like Figure 1 , 2 As shown, a photovoltaic support comprises:

[0076] Photovoltaic panel bracket 12, used for installing photovoltaic panels;

[0077] Base 1;

[0078] The power mechanism includes a driving member 20 and a transmission shaft 21, one end of the transmission shaft 21 is transmission-connected to the driving member 20, and the other end is rotatably disposed on the base 1; the transmission shaft 21 includes a first transmission shaft section and a second transmission shaft section, wherein the first transmission shaft section is disposed closer to the base 1 than the second transmission shaft section;

[0081] In this embodiment, the base 1 serves as the base of the photovoltaic bracket and is directly fixedly assembled with the mounting surface, so that the photovoltaic bracket as a whole has good stability and improves the overall windproof performance of the photovoltaic bracket. The base 1 is a cylindrical trough structure, and the inner wall of the base 1 is provided with internal meshing teeth, which mesh with the first driven gear 3. The first adjustment mechanism and the second adjustment structure work simultaneously through the operation of the driving member 20. The specific working method is to drive the first driving gear 4 to rotate, and the rotation of the first driving gear 4 drives the first driven gear 3 to rotate, so that the rotating frame 2 rotates on the base 1. The setting of the internal meshing teeth further improves the overall rotation stability of the rotating frame 2. Qualitatively, the rotation of the rotating frame 2 drives the lifting frame and the lifting mechanism to rotate synchronously, and the photovoltaic panel bracket 12 rotates accordingly. The photovoltaic panel bracket 12 is used to fix the photovoltaic panel unit 16. The photovoltaic panel bracket 12 can be lifted and adjusted through the lifting frame and the lifting mechanism while rotating. The lifting adjustment is the adjustment of the angle between the photovoltaic panel bracket 12 and the horizontal direction. The photovoltaic bracket can work through the single transmission shaft 21 of the driving member 20 and adjust the circumferential rotation direction of the photovoltaic panel bracket 12 at the same time, so as to more conveniently track the solar radiation, so as to achieve the real-time reception of a large amount of solar radiation, and at the same time provide convenience for reducing the angle between the photovoltaic panel bracket 12 and the horizontal direction at any time and adjusting it to the wind protection mode.

[0082] The driving member 20 includes a motor, a coupling and other motor components. The driving member 20 is assembled on the upper side of the first driving gear 4, and the transmission shaft 21 serves as the output shaft of the driving member 20.

[0086] The plurality of spokes include a first spoke 201, a second spoke 202, and a third spoke 203. A first driven gear A 301 is disposed at the end of the first spoke 201, a first driven gear B 302 is disposed at the end of the second spoke 202, and a first driven gear C 303 is disposed at the end of the third spoke 203;

[0088] In this embodiment, the number of spokes is 3, and the number of the first driven gears 3 is also 3. The lifting mechanism changes the height of the first frame body 501, acting on the photovoltaic panel bracket 12 to change the angle between the photovoltaic panel bracket 12 and the horizontal direction.

[0090] the lifting mechanism includes a lead screw 9, a second driving gear 11, and a second driven gear 10;

[0091] The second driving gear 11 is sleeved on the second transmission shaft section or integrally formed by the second transmission shaft section;

[0092] The first frame body 501 is provided with a threaded hole in transmission cooperation with the lead screw 9. One end of the lead screw 9 is in transmission cooperation with the threaded hole of the first frame body 501, and the other end is fixedly connected to the second driven gear 10. The second driven gear 10 is in external meshing transmission connection with the second driving gear 11 provided on the second transmission shaft section;

[0093] The lifting mechanism further includes a first connecting plate 6 and a guide rod 8. The first connecting plate 6 is connected between the axles of the first driven gear A 301 and the first driven gear B 302; the guide rod 8 is arranged in parallel with the lead screw 9, one end of which is fixed on the first connecting plate 6, and the other end is in sliding cooperation with the first frame body 501.

[0094] In this embodiment, the number of the guide rods 8 is 2, and the number of the lead screws 9 is 1. The two guide rods 8 are located on both sides of the lead screw 9. The guide rods 8 and the first connecting plate 6 together form a U-shaped frame structure. By rotating the transmission shaft 21, the second transmission shaft section drives the second driving gear 11 to rotate. The second driving gear 11 rotates to drive the second driven gear 10 to rotate. The second driven gear 10 rotates to drive the lead screw 9 to rotate, which can force the first frame body 501 to move along the axial direction of the guide rod 8. One end of the first frame body 501 acts on one end of the photovoltaic panel bracket 12 to lift one end of the photovoltaic panel bracket 12. The other end of the photovoltaic panel bracket 12 does not make a lifting displacement but only cooperates with the rotation, so as to change the angle between the photovoltaic panel bracket 12 and the horizontal direction.

[0095] Optionally, in one implementation of this embodiment, as Figure 1 shown

[0096] The second transmission shaft section is provided with a second driving gear 11;

[0097] The lifting mechanism includes a lead screw 9, a sliding block 22, a second driving gear 11 and a second driven gear 10;

[0098] The second driving gear 11 is sleeved on the second transmission shaft section or integrally formed by the second transmission shaft section;

[0100] The lifting mechanism further includes a first connecting plate 6 and a guide rod 8. The first connecting plate 6 is connected between the axle of the first driven gear A 301 and the axle of the first driven gear B 302; The guide rod 8 is arranged parallel to the lead screw 9. One end of it is fixed on the first connecting plate 6, and the other end is in sliding cooperation with the first frame body 501.

[0101] In this embodiment, the number of the arranged guide rods 8 is 2, and the number of the arranged lead screws 9 is 1. The two guide rods 8 are located on both sides of the lead screw 9. The guide rod 8 and the first connecting plate 6 together form a C-shaped frame structure. By rotating the transmission shaft 21, the second transmission shaft section drives the second driving gear 11 to rotate. The rotation of the second driving gear 11 drives the second driven gear 10 to rotate. The rotation of the second driven gear 10 drives the lead screw 9 to rotate, which can force the sliding block 22 to move axially along the guide rod 8. The sliding block 22 drives the first frame body 501 to move axially along the guide rod 8. One end of the first frame body 501 acts on one end of the photovoltaic panel bracket 12, so that one end of the photovoltaic panel bracket 12 is lifted. The other end of the photovoltaic panel bracket 12 does not make a lifting displacement but only cooperates with the rotation, thereby changing the included angle between the photovoltaic panel bracket 12 and the horizontal direction.

[0102] Through the above method, the single transmission shaft 21 of the driving member 20 works while adjusting the circumferential rotation direction of the photovoltaic panel bracket 12, which is more convenient for tracking solar radiation, achieving real-time maintaining the reception of a relatively large amount of solar radiation, and at the same time providing convenience for reducing the included angle between the photovoltaic panel bracket 12 and the horizontal direction at any time and adjusting to the windproof mode.

When the frame is simple and coordinated for use, the four points extended by the four vertical plates provide installation positions for the connecting pins. The end of the photovoltaic panel bracket 12 connected to the connecting pin 14 can be raised and lowered due to the setting of the limiting slide groove 13, which facilitates the lifting and lowering movement of the photovoltaic panel bracket 12.

[0120] The photovoltaic panel is composed of a plurality of photovoltaic panel units 16 , and the plurality of photovoltaic panel units 16 are detachably connected to the photovoltaic panel bracket 12 .

[0121] In this embodiment, the buckle 17 is composed of a screw and a pressing plate assembly. The pressing plate is locked by the screw, and the pressing plate presses the photovoltaic panel unit 16. This design method facilitates the replacement of the photovoltaic panel unit 16.

[0122] Optionally, in an implementation of this embodiment, as Figure 2 As shown,

[0123] The photovoltaic module also includes a control mechanism;

[0124] The control mechanism includes a mounting frame 18, an azimuth angle indicator column 19, a sensor assembly, and a controller;

[0125] The mounting frame 18 is connected to the second frame body 502, and the azimuth angle indicating column 19 is connected to the mounting frame 18 and is parallel to the transmission shaft 21;

[0126] The sensing component includes a first angle sensor and a light-sensitive sensor;

[0127] The photosensor is placed at the center of the photovoltaic panel, and is used to cooperate with the azimuth indicator column 19 to obtain the optimal angle value for the photovoltaic panel to receive solar radiation. The first angle sensor is placed on the transmission shaft 21, and is used to obtain the rotation position of the transmission shaft 21 when the photovoltaic panel receives solar radiation at the optimal angle. The controller controls the first adjustment mechanism to rotate the photovoltaic panel bracket 12 to the optimal angle position for the photovoltaic panel to receive solar radiation based on the information obtained by the cooperation between the photosensor and the azimuth indicator column 19 and the first angle sensor.

[0128] The sensing assembly also includes a wind pressure sensor and a second angle sensor. The wind pressure sensor is placed on the side of the photovoltaic panel bracket 12 facing away from solar radiation, and is used to obtain the real-time wind pressure value borne by the photovoltaic panel bracket 12. The second angle sensor is placed on the photovoltaic panel bracket 12, and is used to obtain the real-time inclination angle of the photovoltaic panel bracket 12 with the horizontal direction.

[0129] In this embodiment, after being exposed to the sun, the azimuth indicator column 19 has a projection on the photovoltaic panel unit 16 because it blocks the sunlight. When the projection blocks the photosensor, it proves that the photovoltaic panel unit 16 is in a position where it receives a relatively large amount of solar radiation. One of the angle sensors corresponds to recording the current angular position of the transmission shaft 21. The controller controls the photovoltaic component to rotate one circle and finds the optimal radiation position. The driving member 20 drives the photovoltaic component to return to the optimal radiation position according to the angular position recorded by the angle sensor on the transmission shaft 21 to receive a larger amount of radiation. The optimal radiation position is tracked repeatedly every cycle. The photovoltaic component receives solar radiation with high efficiency and achieves a relatively high power generation.

[0130] When the wind pressure in the external environment is high, the photovoltaic assembly needs to enter the wind protection mode. At this time, the controller controls one end of the photovoltaic panel bracket 12 to lower to reduce its angle with the horizontal direction, thereby achieving a better wind protection effect.

[0131] Embodiment 3

[0132] like Figure 7 As shown, this embodiment provides a control method for a photovoltaic assembly, which is applied to the photovoltaic assembly in the second embodiment, including:

[0133] S10, in response to a photovoltaic module tracking instruction,

[0134] S11, controlling the first adjustment mechanism to drive the photovoltaic panel bracket 12 to rotate, and using the azimuth angle indicator column, the first angle sensor, and the photosensor to determine the optimal angle at which the photovoltaic panel receives solar radiation;

[0135] S12, controlling the first adjustment mechanism to drive the photovoltaic panel bracket 12 to rotate to the optimal angle of solar radiation according to the optimal angle of solar radiation;

[0136] S13. Repeat steps S11 and S12 at every set period.

[0137] The control method in this embodiment is used to achieve the tracking of the photovoltaic component to the optimal radiation position. The period TO is a preset rated value and can be set as needed. Every other period T0, the controller controls the driving member 20 to work, driving the photovoltaic panel bracket 12 to rotate one circle, and obtaining the optimal angle of solar radiation during the rotation. The specific searching method is that after being irradiated by the sun, the azimuth angle indicator column 19 has a projection on the photovoltaic panel unit 16 because it blocks the sunlight. When the projection blocks the photosensor, it proves that the photovoltaic panel unit 16 is in a position where it receives a relatively large amount of solar radiation. The angle sensor correspondingly records the current angular position of the transmission shaft 21. After the photovoltaic component rotates one circle, the optimal radiation position is found, and the driving member 20 is controlled to work, driving the photovoltaic panel bracket 12 to rotate to the optimal angle of solar radiation, and the photovoltaic panel unit 16 receives solar radiation.

[0138] In this embodiment, the tracking of the optimal angle position of solar radiation may also be converted into real-time tracking without responding to the tracking instruction;

[0139] S30, using the azimuth indicator column, the first angle sensor, and the photosensor to detect in real time whether the photovoltaic panel is at an optimal angle position for receiving solar radiation;

[0140] S31. If the photovoltaic panel is not at an optimal angle position for receiving solar radiation, control the first adjustment mechanism to drive the photovoltaic panel bracket 12 to rotate so that the photovoltaic panel is at an optimal angle position for receiving solar radiation.

[0141] Those skilled in the art will appreciate that, in this embodiment, the optimal angle of solar radiation is a preset maximum angle value of the received solar radiation extracted after the photovoltaic panel bracket rotates one circle, that is, the optimal is a relative optimal within a certain range.

[0142] Embodiment 4

[0143] like Figure 8 As shown, this embodiment provides a control method for a photovoltaic assembly, which is applied to the photovoltaic assembly in the second embodiment, including:

[0144] S20, in response to the photovoltaic module wind protection instruction,

[0145] S21, obtaining a wind pressure value P detected by the wind pressure sensor and an inclination angle α of the photovoltaic panel bracket 12 detected by the second angle sensor, wherein the wind pressure value P borne by the photovoltaic panel bracket 12 is the wind pressure value borne by the back of the photovoltaic panel bracket 12 and the inclination angle α of the photovoltaic panel bracket 12 detected by the second angle sensor;

[0146] S22, comparing the wind pressure value P of the photovoltaic panel bracket 12 with the preset rated wind pressure value P0 and the preset maximum wind pressure threshold value Pm:

[0147] S23, controlling the inclination angle α of the photovoltaic panel bracket 12 according to the comparison result:

[0148] S231, if P<P0, keep the inclination angle α of the photovoltaic panel bracket 12 unchanged;

[0149] S232, if P≥Pm, control the second adjustment mechanism to drive the lifting frame 5 to lower so that the inclination angle α of the photovoltaic panel bracket reaches a preset minimum inclination angle threshold αm;

[0150] S233. If P0≤P<Pm, control the second adjustment mechanism to drive the lifting frame 5 to lower so that the inclination angle α of the photovoltaic panel bracket becomes α-α1, and repeat S22 and S23 until P<P0 or the inclination angle α of the photovoltaic panel bracket 12 reaches the preset minimum inclination angle threshold αm.

[0151] The control method in this embodiment is used to realize the wind protection function of the photovoltaic module. In severe weather conditions, when the photovoltaic module receives a wind protection instruction,

[0152] The wind pressure value P borne by the photovoltaic module and the tilt angle α of the photovoltaic panel bracket 12 are obtained through the wind pressure sensor and the angle sensor;

[0153] The preset rated wind pressure value P0, the preset maximum wind pressure value Pm, the minimum tilt angle threshold αm, and the preset rated tilt angle α1 are all preset rated values;

[0154] The real-time value is compared with the preset rated value, and then the tilt angle of the photovoltaic panel bracket 12 is adjusted to achieve a further wind protection effect.

[0155] Specifically, if P≥Pm, the controller controls the driving member 20 to work, driving one end of the photovoltaic panel bracket 12 to be lowered, so that α=αm. At this time, the inclination angle of the photovoltaic panel bracket 12 with the horizontal direction reaches the minimum, that is, the windward surface reaches the minimum, and the windproof effect reaches the best;

[0156] If P<Pm, compare P and P0;

[0157] If P<P0, α is kept unchanged. At this time, the real-time wind pressure on the photovoltaic panel bracket 12 is small, and the current angle can be kept unchanged;

[0158] If P0≤P<Pm, the second adjustment mechanism is controlled to drive the lifting frame 5 to lower, so that the inclination angle α of the photovoltaic panel bracket becomes α-α1, and S22 and S23 are repeated until P<P0 or the inclination angle α of the photovoltaic panel bracket 12 reaches the preset minimum inclination angle threshold αm. That is, the adjustment is performed in a step-by-step manner to reduce the angle so that the photovoltaic panel bracket 12 can achieve a suitable windproof effect.

[0159] For the detection of the wind pressure value and the tilt angle of the photovoltaic panel bracket 12, preferably, the wind pressure sensor and the second angle sensor are detected in real time, for example, they can be in the detection state all the time, or they can be detected at a set frequency. These are all real-time detections to ensure dynamic understanding of the wind pressure value. Of course, it is also feasible in this patent to detect the wind pressure value P and the tilt angle α of the photovoltaic panel bracket 12 when the photovoltaic component wind protection instruction is triggered.

[0160] The control of the tilt angle can be carried out according to the preset relationship between wind pressure value - tilt angle - motor rotation time. For example, when the current wind pressure value is P1, the corresponding tilt angle α1 can be found in the table, and then the difference between the current tilt angle α and α1 is calculated. The operation time of the drive member 20 is calculated based on the difference, and the lifting mechanism is lowered to reduce α to a distance of α-α1.

[0161] In summary, the ingenious design of photovoltaic brackets and photovoltaic modules lies in:

[0162] First, the base is used as the pedestal of the photovoltaic bracket and is directly fixed and assembled with the mounting surface, so that the photovoltaic bracket as a whole has good stability and improves the overall wind resistance of the photovoltaic bracket.

[0163] Secondly, the gear structure and the screw structure are cleverly combined. Through the single transmission shaft of the driving part, the circumferential rotation direction of the photovoltaic panel bracket can be adjusted at the same time, so as to more conveniently track solar radiation and achieve real-time reception of a large amount of solar radiation. At the same time, it provides convenience for reducing the angle between the photovoltaic panel bracket and the horizontal direction at any time and adjusting it to a windproof mode.

[0164] Third, by controlling the photovoltaic modules, the photovoltaic modules can track the locations with larger radiation and prevent wind.
