Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic panels, and in particular to an energy-saving electric photovoltaic bracket assembly with adjustable angle. Background Art

[0002] Photovoltaic brackets are a key component in solar power generation systems. They are mainly used to install and support solar panels to ensure that they can effectively receive sunlight and convert it into electrical energy. During the use of photovoltaic panels, the sun's position changes over time every day. That is, the sun is at its highest point and the light intensity is the highest at noon, while the sun is close to the horizon in the morning and afternoon. Sunlight usually shines on the photovoltaic panels at a larger incident angle, causing part of the light to be reflected and unable to be fully absorbed, thereby reducing the utilization rate of sunlight. Therefore, in order to ensure that the photovoltaic panels always maintain the best light reception angle, the angle of the photovoltaic bracket needs to be adjustable to improve the illumination intensity and power generation efficiency of the photovoltaic panels.

[0003] However, there are usually some problems in the use of current photovoltaic panel brackets. With the development of science and technology, technicians in related fields have also carried out a lot of optimization on photovoltaic panel brackets. In order to make a more accurate comparison, a Chinese patent with publication number CN108183666A discloses an adjustable photovoltaic bracket, including a supporting member, which is arranged on the top of the adjustable photovoltaic bracket; a base member, one side edge of which is hinged to the supporting member and connected to the supporting member through a first adjustment component; the base member is connected to the support member through a second adjustment component, the first adjustment component includes a rack, the rack is connected to the first motor through a transmission box, one end of the rack is inserted in the rack box, and the other end is hinged to the upper cross bar through a first hinge; the second adjustment component includes a receiving member, a frame member and a second motor, and the second motor is connected to the ruler ring through a second transmission box.

[0004] When the above-mentioned prior art adjusts the photovoltaic panel support, the first motor controls the linear telescopic movement of the rack, and the upper cross bar hinged with the rack can adjust its position under the telescopic movement of the rack, thereby ultimately achieving the effect of controlling the overall pitch angle of the supporting member; when the second motor drives the second transmission box and the ruler ring to rotate, the base member as a whole and the upper structure can rotate with the ruler ring, thereby ultimately achieving the effect of adjusting the azimuth angle of the overall structure of the present invention.

[0005] However, there are still some shortcomings in the process of adjusting the photovoltaic panel bracket in the above-mentioned prior art:

[0006] 1. Since the photovoltaic panels are in a tilted state facing the sun for a long time, they tend to rotate downward under the action of gravity. However, after the above-mentioned prior art adjusts the pitch angle of the photovoltaic panels, it is impossible to limit and lock them accordingly, which makes it easy for the photovoltaic panels to change their pitch angle under the action of gravity or wind when used for a long time, making it difficult to maintain the optimal lighting angle, thereby affecting the power generation efficiency.

[0007] 2. Photovoltaic panels improve the utilization rate of solar energy and obtain more electricity. Usually, a large number of photovoltaic panels are laid in designated locations, so as to fully utilize land resources. Therefore, when adjusting the photovoltaic panel bracket according to the angle of sunlight, multiple photovoltaic panel brackets need to be adjusted. However, the above-mentioned prior art can only complete the angle adjustment of one photovoltaic panel bracket at a time, and cannot achieve synchronous adjustment of multiple photovoltaic panel brackets, which makes the operation cumbersome and affects the adjustment efficiency.

[0008] Therefore, based on the above-stated viewpoints, there is still room for improvement in the existing photovoltaic panel support adjustment methods. Summary of the invention

[0040] The following is combined with Figure 1-Figure 13 Embodiments of the present invention are described in detail.

[0041] The embodiment of the present application discloses an energy-saving electric photovoltaic bracket assembly with adjustable angle. It should be noted that the energy-saving electric photovoltaic bracket assembly with adjustable angle of the present application is mainly used in the process of adjusting the angle of the photovoltaic panel 6. In terms of technical effect, it can adaptively adjust the angle of the photovoltaic panel 6 according to the azimuth of the sun, and can synchronously adjust multiple photovoltaic panels 6 at the same time to improve the adjustment efficiency, so that the irradiation surfaces of multiple photovoltaic panels 6 are always facing the sun, thereby reducing the reflection of sunlight after irradiating the photovoltaic panel 6 and reducing the irradiation intensity, thereby ensuring the power generation efficiency of the photovoltaic panel 6; in particular, after the angle of the photovoltaic panel 6 is adjusted, it can be limited, and the angle of the photovoltaic panel 6 will not change randomly, so as to ensure the stability of the photovoltaic panel 6 after adjustment and its irradiation intensity; further, the energy-saving electric photovoltaic bracket assembly with adjustable angle can also move multiple photovoltaic panels 6 up and down when the azimuth angle of the photovoltaic panel 6 is adjusted, so that the multiple photovoltaic panels 6 are staggered up and down, so as to avoid the photovoltaic panel 6 on the side away from the sun being blocked after the azimuth angle of the photovoltaic panel 6 is adjusted, thereby affecting the light intensity and power generation efficiency.

[0042] Embodiment 1:

[0043] Reference Figure 1 , Figure 2 and Figure 3 As shown, an energy-saving electric photovoltaic bracket assembly with adjustable angle includes a plurality of bracket bodies 1 distributed at equal intervals, an inclined plate 2 is installed on the upper end of the bracket body 1, the inclined plate 2 gradually tilts upward on the side away from the bracket body 1, a worm 3 is rotatably arranged on the upper end of the bracket body 1, a receiving member is installed between two adjacent worms 3, a connecting frame 22 is rotatably installed on the inclined plate 2 through an annular cylinder 21, a worm wheel 24 meshing with the worm 3 is fixedly sleeved on the connecting frame 22 through a positioning shaft 23, an actuator plate 4 is installed on the side of the connecting frame 22 away from the worm 3, a photovoltaic panel 6 is arranged on the actuator plate 4 through an adjustment unit 5, the adjustment unit 5 is used to adjust the pitch angle of the photovoltaic panel 6, the adjustment unit 5 includes a fixed block 51 installed on the side of the actuator plate 4 away from the connecting frame 22, and the fixed block 51 and the photovoltaic panel 6 are hinged through a pin 52.

[0044] During the specific implementation process, after the photovoltaic panel 6 is installed on the actuator plate 4, the worm gear 24 is driven to rotate by rotating the worm 3. When the worm gear 24 rotates, the actuator plate 4 is driven to rotate synchronously through the positioning shaft 23 and the connecting frame 22, so that the actuator plate 4 drives the photovoltaic panel 6 to rotate synchronously, so as to adjust the azimuth angle of the photovoltaic panel 6 according to the position of the sun, so that the photovoltaic panel 6 can be adaptively adjusted according to the position of the sun in the morning and afternoon; in the process of the connecting frame 22 driving the actuator plate 4 and the photovoltaic panel 6 to rotate and adjust, the annular cylinder 21 can support and limit the connecting frame 22, the actuator plate 4 and the photovoltaic panel 6, so as to ensure the stability of the photovoltaic panel 6 during the angle adjustment process, and further ensure the use effect of the present invention.

[0045] In addition, the photovoltaic panel 6 can form a rotational connection between the pin shaft 52 and the fixed block 51. At this time, the pitch angle of the photovoltaic panel 6 can be adjusted through the adjustment unit 5, so that the photovoltaic panel 6 can be adaptively adjusted with the height of the sun; in this way, the photovoltaic panel 6 can automatically adjust the angle according to the direction of the sun, so that the photovoltaic panel 6 can track the sun, thereby improving the illumination intensity and power generation efficiency.

[0046] Reference Figure 3 and Figure 4 As shown, in order to facilitate automatic adjustment of the azimuth angle of the photovoltaic panel 6, it is necessary to control the worm 3 to rotate automatically. Based on this, in this embodiment, a mounting groove is opened at the upper end of the bracket body 1, and a rotating shaft 11 is rotatably arranged in the mounting groove. The worm 3 is sleeved on the outer wall of the rotating shaft 11, and a driving motor 12 is installed on any one of the bracket bodies 1 through a motor seat. The output shaft of the driving motor 12 is connected to the rotating shaft 11, and a controller 13 is provided on any one of the inclined plates 2. The driving motor 12 and the controller 13 are electrically connected, and a limiting unit 14 for preventing the worm 3 from rotating is installed between the worm 3 and the bracket body 1.

[0047] It should be noted that the controller 13 used in this embodiment is a prior art, which is mainly used to control the start and stop of the drive motor 12. The working principle of the controller 13 will not be described here.

[0048] During the specific implementation process, the driving motor 12 is powered on and started through the controller 13, and the driving motor 12 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the worm 3 to rotate synchronously, so that the worm 3 drives the worm wheel 24 to rotate, so that the worm wheel 24 can drive the actuator plate 4 and the photovoltaic panel 6 to rotate through the connecting frame 22, so as to adjust its azimuth angle; in addition, the photovoltaic panel 6 can rotate in the opposite direction by driving the worm 3 to rotate in the driving motor 12, so as to facilitate the adaptive adjustment of the photovoltaic panel 6 according to the direction of the sun, so that the irradiation surface of the photovoltaic panel 6 is always facing the sun, so that the photovoltaic panel 6 can always receive the sun's light, reduce the reflection of sunlight after it hits the photovoltaic panel 6 and reduce the irradiation intensity, thereby ensuring the power generation efficiency of the photovoltaic panel 6.

[0049] Reference Figure 5 As shown, in order to prevent the rotating worm 3 from cooperating with the worm wheel 24 to control the photovoltaic panel 6 to adjust the azimuth angle and not rotating randomly, it is necessary to limit the photovoltaic panel 6 accordingly. Based on this, a limit unit 14 is provided in this embodiment. Specifically, the limit unit 14 includes a circular groove opened on the inner wall of the worm 3, and the circular groove has a plurality of annularly distributed tooth grooves at either end close to the worm 3, and a receiving groove is provided at the other end of the circular groove. The outer wall of the rotating shaft 11 is sleeved with a spline shaft 141 that matches the tooth groove; in the initial state, the spline shaft 141 is located in the receiving groove, so that the rotating shaft 11 and the worm 3 are in relative rotation, and the rotating shaft 11 cannot drive the worm 3 to rotate at this time; a telescopic rod 142 is slidably arranged inside the rotating shaft 11, and a plurality of annularly distributed sliding holes 143 are evenly opened on the rotating shaft 11, and a plurality of connecting strips 144 that slide through the sliding holes 143 are installed between the outer wall of the telescopic rod 142 and the spline shaft 141.

[0050] It should be noted that the connecting bar 144 can enable the rotating shaft 11 and the telescopic rod 142 to rotate synchronously, and then the telescopic rod 142, the rotating shaft 11 and the spline shaft 141 to rotate synchronously without affecting the sliding fit between the spline shaft 141 and the rotating shaft 11.

[0051] During the specific implementation process, by controlling the extension and contraction of the telescopic rod 142, the telescopic rod 142 drives the spline shaft 141 to move along the sliding hole 143 through the connecting strip 144, so that the spline shaft 141 is inserted into the tooth groove, so that the rotating shaft 11 can drive the worm 3 to rotate synchronously, and then adjust the azimuth angle of the photovoltaic panel 6 through the mutual cooperation of the worm 3 and the worm wheel 24; after the adjustment of the photovoltaic panel 6 is completed, the telescopic rod 142 drives the spline shaft 141 to reset to the accommodating groove, so that the relative rotation between the rotating shaft 11 and the worm 3 is restored, thereby avoiding the rotating shaft 11 driving the worm 3 to rotate at will and causing the azimuth angle of the photovoltaic panel 6 to change.

[0052] Reference Figure 6 As shown, in order to prevent the rotating shaft 11 from rotating randomly when the rotating shaft 11 and the worm 3 are in a relative rotation state, thereby causing the rotation of the worm 3, and further affecting the change of the azimuth angle of the photovoltaic panel 6, it is necessary to perform corresponding limit fixation on the rotating shaft 11. Based on this, in the present embodiment, both ends of the rotating shaft 11 are fixedly sleeved with a linkage ring 15 after extending out of the bracket body 1, and the bracket body 1 is provided with an annular frame 16 coaxial with the linkage ring 15, the diameter of the annular frame 16 is larger than the diameter of the linkage ring 15, and the outer wall of the linkage ring 15 is evenly provided with a plurality of annularly distributed grooves, and the inner wall of the annular frame 16 is installed with a plurality of interference blocks 18 corresponding to the positions of the grooves through supporting spring rods 17.

[0053] It should be noted that the supporting spring rod 17 always applies a top contact force to the contact block 18, so that the contact block 18 is forced to press against the groove, so that the rotation direction of the rotating shaft 11 can be limited by the mutual cooperation between the contact block 18 and the groove, so that when the telescopic rod 142 drives the spline shaft 141 to be located in the accommodating groove, the rotating shaft 11 and the worm 3 are in relative rotation. Since the rotating shaft 11 will not rotate arbitrarily when not subject to other external forces, it will not cause the worm 3 to rotate arbitrarily, and will not cause the azimuth angle of the photovoltaic panel 6 to change arbitrarily, thereby ensuring the stability of the photovoltaic panel 6 after adjustment and its irradiation intensity.

[0054] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in order to realize automatic switching of the rotation state between the worm 3 and the rotating shaft 11, in the present embodiment, a positioning plate 20 is installed on the side of the bracket body 1 close to the driving motor 12, and the end of the telescopic rod 142 away from the cylinder 19 rotates through the positioning plate 20, and the telescopic rod 142 close to the driving motor 12 passes through the positioning plate 20 and is connected to the output shaft of the driving motor 12. The positioning plate 20 can limit the end of the telescopic rod 142 close to the driving motor 12, and the other end of the telescopic rod 142 can be freely extended and retracted and drive the spline shaft 141 to cooperate with the tooth groove or reset to the accommodating groove. In addition, the multiple telescopic joints of the telescopic rod 142 used in the present embodiment can only slide relative to each other and cannot rotate relative to each other, so that the output shaft of the driving motor 12 can drive the rotating shaft 11 to rotate through the telescopic rod 142.

[0055] Furthermore, in the present embodiment, the receiving member is a cylinder 19 connected between two adjacent telescopic rods 142, and the cylinder 19 and the controller 13 are electrically connected; the cylinder 19 is electrically started through the controller 13, and the cylinder 19 can drive the spline shaft 141 to be inserted into the tooth groove or retracted into the accommodating groove through the telescopic rod 142, so as to control the automatic switching of the rotation state between the rotating shaft 11 and the worm 3, and the telescopic end of the cylinder 19 is connected to the end of the telescopic rod 142 close to the driving motor 12, and the fixed end of the cylinder 19 is connected to the positioning plate 20 adjacent to the telescopic rod 142; in addition, the end of the telescopic rod 142 away from the driving motor 12 is also installed with a cylinder 19, and the cylinder 19 is connected to the bracket body 1 through a stabilizing frame.

[0056] Reference Figure 7As shown, since the photovoltaic panel 6 has a certain weight, the connecting frame 22 and the actuator plate 4 are subjected to gravity. Therefore, in order to ensure the stability of the photovoltaic panel 6, in this embodiment, an arc plate 25 is installed on the side of the inclined plate 2 close to the connecting frame 22, and an arc groove 26 is provided on the side of the arc plate 25 away from the inclined plate 2. A support block 27 that slides and docks in the arc groove 26 is installed on the side of the connecting frame 22 close to the arc plate 25, and an arc groove is provided on the side of the arc plate 25 close to the actuator plate 4. A top support block 28 that slides and docks in the arc groove is installed on the side of the actuator plate 4 close to the arc plate 25; the arc plate 25, the arc groove 26 and the arc groove are all on the same axis as the annular cylinder 21, so as to ensure that when the actuator plate 4 drives the photovoltaic panel 6 to rotate, the actuator plate 4 is always supported and limited to ensure the stability of the photovoltaic panel 6.

[0057] During the specific implementation process, the connection frame 22 can be supported and limited by the mutual cooperation between the support block 27 and the arc-shaped groove 26, so that the connection frame 22 can firmly support the actuator plate 4 and the photovoltaic panel 6. In addition, the cooperation between the top support block 28 and the arc-shaped groove can further support the actuator plate 4, thereby further ensuring the stability of the actuator plate 4 and the photovoltaic panel 6, avoiding the lack of stability of the photovoltaic panel 6 after adjusting the azimuth angle, resulting in a change in the angle, thereby effectively ensuring that the photovoltaic panel 6 can maintain the optimal light receiving angle.

[0058] Reference Figure 8 and Fig. 9 As shown, due to the constant change in the position of the sun, the angle between the photovoltaic panel 6 and the sun is constantly changing, especially in the morning and evening, when the sun is at a lower angle, making it impossible for the photovoltaic panel 6 to fully receive the sunlight. Therefore, in order to ensure that the photovoltaic panel 6 always maintains the optimal light receiving angle, it is necessary to adjust the pitch angle of the photovoltaic bracket. Based on this, in the present embodiment, the adjustment unit 5 also includes a limiting slide groove opened on the side of the fixed block 51 away from the execution plate 4, and a top block 53 is slidably arranged in the limiting slide groove. The distance between the bottom wall in the limiting slide groove and the execution plate 4 gradually increases from top to bottom, so that the top block 53 is gradually pushed out to the side away from the execution plate 4 during the sliding process from top to bottom. An auxiliary plate 54 that slides against the top block 53 is installed on the side of the photovoltaic panel 6 close to the fixed block 51, and a threaded rod 55 is rotatably arranged on the fixed block 51. The threaded rod 55 passes through the top block 53 by a threaded connection, and the ends of the threaded rod 55 between the two adjacent fixed blocks 51 are jointly sleeved with a belt.

[0059] It should be noted that the belt can make multiple threaded rods 55 rotate synchronously, and when the photovoltaic panel 6 adjusts the azimuth angle, the multiple actuator plates 4, the fixed blocks 51 and the photovoltaic panel 6 rotate in the same direction as a whole, so that the rotation angles of the threaded rods 55 on the multiple fixed blocks 51 are equal. Therefore, the spacing and parallel state between two adjacent threaded rods 55 will never change, thereby avoiding interference with the belt.

[0060] Furthermore, in the present embodiment, a fixing sleeve at the end of the threaded rod 55 on any one of the fixing blocks 51 is provided with a linkage bevel gear 511, a positioning motor 512 is provided on the side wall of the fixing block 51 through a motor cover, the positioning motor 512 is electrically connected to the controller 13, and an output shaft sleeve of the positioning motor 512 is provided with an active bevel gear 513 meshing with the linkage bevel gear 511.

[0061] It should be further noted that a torsion spring is provided between the photovoltaic panel 6 and the pin shaft 52 , and the torsion spring always applies a torsional force to the photovoltaic panel 6 , so that the bottom of the photovoltaic panel 6 has a tendency to rotate toward the side close to the actuator plate 4 .

[0062] In the specific implementation process, when the pitch angle of the photovoltaic panel 6 needs to be adjusted, the positioning motor 512 is powered on and started through the controller 13, and the positioning motor 512 drives the active bevel gear 513 to rotate, and the active bevel gear 513 drives the threaded rod 55 to rotate through the linkage bevel gear 511, and the threaded rod 55 rotates while driving the top block 53 to move along the length direction of the limiting slide groove; when the threaded rod 55 rotates forward, it drives the top block 53 to move to the side close to the pin shaft 52, and since the length of the top block 53 does not change, the top block 53 cooperates with the auxiliary plate 5 4 can push the photovoltaic panel 6 toward the side away from the fixed block 51, so that the photovoltaic panel 6 rotates upward; when the threaded rod 55 is reversed, the control push block 53 moves toward the side away from the pin shaft 52, and the photovoltaic panel 6 rotates downward under the action of the torsion spring, so that the pitch angle of the photovoltaic panel 6 can be adjusted according to the direction of the sun, and then the worm wheel 24 and the worm 3 can simultaneously adjust the azimuth angle and pitch angle of the photovoltaic panel 6 according to the direction of the sun, so that the photovoltaic panel 6 always maintains the best light receiving angle, thereby improving the irradiation intensity and power generation efficiency of the photovoltaic panel 6.

[0063] Reference Fig. 9 and Fig.10As shown, in order to ensure the stability of the photovoltaic panel 6 during the process of adjusting the pitch angle, in the present embodiment, a sliding groove is provided on the side of the auxiliary plate 54 close to the fixed block 51, and a locking sliding hole is provided on the inner wall of the sliding groove close to the photovoltaic panel 6, and the end of the top block 53 away from the fixed block 51 is slidably docked in the sliding groove, and a linkage column 531 is fixedly penetrated on the side of the top block 53 located in the sliding groove, and the linkage column 531 is slidably docked in the locking sliding hole; it should be noted that the side of the top block 53 close to the auxiliary plate 54 is an arc-shaped structure. When the pitch angle of the photovoltaic panel 6 changes, the photovoltaic panel 6 drives the angle between the auxiliary plate 54 and the top block 53 to change. At this time, interference can be avoided by the arc-shaped structure of the top block 53.

[0064] During the specific implementation process, when the top block 53 moves along the length direction of the limiting slide groove, the top block 53 drives the linkage column 531 to move synchronously. During this period, the top block 53 can push the auxiliary plate 54 upward through the cooperation between the linkage column 531 and the locking slide hole, and prevent the auxiliary plate 54 from falling off the top block 53, thereby ensuring the stability of the photovoltaic panel 6 during the process of adjusting the pitch angle.

[0065] Embodiment 2:

[0066] Reference Fig.11 , Fig.12 and Fig.13 As shown, on the basis of the first embodiment, when the azimuth angle of the photovoltaic panel 6 is adjusted, the multiple photovoltaic panels 6 rotate in the same direction and are divided into multiple independent planes parallel to each other by the same plane. At this time, the photovoltaic panel 6 on the side close to the sun is easy to block the photovoltaic panel 6 on the side away from the sun, resulting in the blocked photovoltaic panel 6 being unable to fully receive the sun's radiation, thereby affecting the power generation efficiency; based on this, in this embodiment, a control unit 7 for staggered arrangement of the multiple photovoltaic panels 6 is also provided, specifically, the control unit 7 includes a connecting block 71, a reciprocating groove is provided on the side of the executive plate 4 close to the fixed block 51, a connecting block 71 is slidably docked in the reciprocating groove, and the fixed block 51 is installed on the connecting block 71; a first fixing rod 72 is provided on the upper side of the inclined plate 2, and a second fixing rod 73 located on the lower side of the inclined plate 2 is installed on the side wall of the bracket body 1, and multiple first fixing rods 72 and second fixing rods 73 are arranged at intervals, and through holes for passing the first fixing rod 72 are provided on the connecting frame 22 and the positioning shaft 23.

[0067] Furthermore, in this embodiment, a positioning wheel 74 is fixedly sleeved on the end of the first fixed rod 72 and the second fixed rod 73 away from the inclined plate 2, and a pull rope 75 is wound around the outer wall of the positioning wheel 74. The end of the pull rope 75 away from the positioning wheel 74 passes through the actuator plate 4 and is connected to the side of the connecting block 71 close to the positioning wheel 74. A contraction spring 76 is installed between the side of the connecting block 71 away from the pull rope 75 and the inner wall of the reciprocating slide groove.

[0068] It should be noted that the contraction spring 76 always applies tension to the connecting block 71, so that the connecting block 71 always has a tendency to move away from the positioning wheel 74. In the initial state, the connecting block 71 is located in the middle of the reciprocating slide groove under the action of the contraction spring 76 and the pull rope 75, so that the multiple photovoltaic panels 6 are flush and in the same plane in the initial state; in addition, the multiple fixed blocks 51 are all equipped with positioning motors 512 through motor covers, and the multiple positioning motors 512 are electrically connected to the controller 13, so that the multiple positioning motors 512 can be powered on and started at the same time through the controller 13 to control the synchronous rotation of the multiple threaded rods 55, and then the threaded rods 55 cooperate with the fixed block 51 to drive the multiple photovoltaic panels 6 to synchronously adjust the pitch angle.

[0069] In the specific implementation process, when the worm 3 rotates to cooperate with the worm gear 24 to drive the actuator plate 4 and the photovoltaic panel 6 to rotate to adjust the azimuth, the actuator plate 4 moves circumferentially along the positioning wheel 74, and the actuator plate 4 drives the connecting block 71 to move synchronously. Since the positioning wheel 74 does not rotate, the pull rope 75 can be wound around the positioning wheel 74 during the movement of the actuator plate 4, and then the positioning wheel 74 applies a pulling force to the connecting block 71 through the pull rope 75, so that the connecting block 71 drives the fixed block 51 and the photovoltaic panel 6 to move along the reciprocating slide groove, and the movement directions of the two adjacent photovoltaic panels 6 are opposite, so that the multiple photovoltaic panels 6 are staggered up and down (in Fig.13 ), so as to avoid the photovoltaic panel 6 on the side away from the sun being blocked after adjusting the azimuth angle of the photovoltaic panel 6, thereby affecting the light intensity and power generation efficiency.

[0070] During operation: The first step: by controlling the extension and contraction of the telescopic rod 142, the telescopic rod 142 drives the spline shaft 141 to move along the sliding hole 143 through the connecting strip 144, so that the spline shaft 141 is inserted into the tooth groove, so that the rotating shaft 11 can drive the worm 3 to rotate synchronously; then the driving motor 12 is powered on and started through the controller 13, the driving motor 12 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the worm 3 to rotate synchronously, so that the worm 3 drives the worm wheel 24 to rotate, so that the worm wheel 24 can drive the actuator plate 4 and the photovoltaic panel 6 to rotate through the connecting frame 22, so as to adjust its azimuth angle.

[0071] In addition, by driving the worm 3 to rotate in the opposite direction through the driving motor 12, the photovoltaic panel 6 can rotate in the opposite direction, so as to facilitate the adaptive adjustment of the photovoltaic panel 6 according to the direction of the sun, so that the irradiated surface of the photovoltaic panel 6 always faces the sun, so that the photovoltaic panel 6 can always receive sunlight.

[0072] Step 2: After the azimuth angle of the photovoltaic panel 6 is adjusted, the telescopic rod 142 drives the spline shaft 141 to return to the accommodating groove, so that the relative rotation between the rotating shaft 11 and the worm 3 is restored, thereby preventing the rotating shaft 11 from driving the worm 3 to rotate randomly and causing the azimuth angle of the photovoltaic panel 6 to change.

[0073] Step 3: When the pitch angle of the photovoltaic panel 6 needs to be adjusted, the positioning motor 512 is powered on and started through the controller 13, and the positioning motor 512 drives the active bevel gear 513 to rotate, and the active bevel gear 513 drives the threaded rod 55 to rotate through the linkage bevel gear 511. When the threaded rod 55 rotates, it drives the top block 53 to move along the length direction of the limiting slide groove.

[0074] When the threaded rod 55 rotates forward, it drives the top block 53 to move toward the side close to the pin shaft 52 and cooperates with the auxiliary plate 54 to push the photovoltaic panel 6 toward the side away from the fixed block 51, so that the photovoltaic panel 6 rotates upward; when the threaded rod 55 is reversed, it controls the top block 53 to move toward the side away from the pin shaft 52. At this time, the photovoltaic panel 6 rotates downward under the action of the torsion spring, so that the pitch angle of the photovoltaic panel 6 can be adjusted according to the direction of the sun, and then, in cooperation with the worm gear 24 and the worm 3, the azimuth angle and pitch angle of the photovoltaic panel 6 can be adjusted simultaneously according to the direction of the sun, so that the photovoltaic panel 6 always maintains the optimal light receiving angle, thereby improving the illumination intensity and power generation efficiency of the photovoltaic panel 6.

[0075] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
