Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and particularly relates to a two-axis tracking photovoltaic bracket. Background Art

[0002] A two-axis tracking photovoltaic bracket is a photovoltaic power generation device that uses two sets of mirrors or photovoltaic panels to track the direction of sunlight, thereby maximizing the absorption efficiency of the photovoltaic panels. A two-axis tracking photovoltaic bracket usually consists of a control system and a driver. The control system continuously detects the angle and position of sunlight and sends signals to the driver, which then adjusts the angle of the photovoltaic bracket according to the instructions of the control system, so that the photovoltaic panels always face the sun. Different from traditional fixed photovoltaic brackets, a two-axis tracking photovoltaic bracket can adapt to different light conditions and weather conditions by changing its angle. Therefore, it can utilize solar energy more effectively and generate more electricity.

[0003] The two-axis tracking photovoltaic bracket is easily damaged in a harsh environment. When the wind is strong, the photovoltaic bracket may be subjected to large vibrations and impacts, which may cause damage or detachment of the photovoltaic components. At the same time, strong winds will also blow dust and dirt onto the surface of the photovoltaic bracket, which may scratch or damage the coating or seal of the photovoltaic component surface, and the dust and dirt will adhere to the surface of the photovoltaic component, affecting its reflection and absorption effects, thereby reducing its photoelectric conversion efficiency. In order to reduce the impact of dust on the solar panel, the dust on the surface of the solar panel is generally cleaned regularly. At the same time, in order to reduce the impact of the harsh environment on the stability of the photovoltaic bracket, in the prior art, structures such as diagonal bars are generally added to the photovoltaic bracket to protect and stabilize the photovoltaic bracket. However, in actual use, especially when the change range is large during the occurrence of a harsh environment, it is still difficult to avoid the impact on the photovoltaic bracket only by adding diagonal bars or other structures, thereby affecting the normal use of the solar panel.

[0004] In view of the problems existing in the above prior art, we designed a two-axis tracking photovoltaic bracket that reduces the damage of the photovoltaic bracket in a harsh environment with drastic changes and affects the stability during the operation of the solar panel.

[0067] Spray nozzles, and a plurality of the spray nozzles are equally angularly connected at positions on the mounting frame corresponding to the solar panel.

[0068] The working principle and beneficial effects of the present invention are as follows:

[0069] 1. In the present invention, the second motor drives two driven bevel gears to rotate in opposite directions simultaneously through the driving bevel gear, thereby driving two rotating rings to rotate in opposite directions simultaneously. The two rotating rings respectively drive the corresponding second torsion springs to rotate. Since the directions of the two second torsion springs are opposite, both of the two second torsion springs can be wound around the connecting rod while the rotating ring rotates, improving the tensile force between the second torsion spring and the connecting rod. And due to the setting of the two second torsion springs, the connecting rod is kept relatively balanced, so that when encountering bad weather, the connecting rod swings with a smaller amplitude, improving the stability of the mounting frame.

[0070] 2. In the present invention, when encountering bad weather, the bearing frame drives the annular plate to shift in the position-adjusting frame. At this time, the first spring is compressed, thereby offsetting the force acting on the mounting frame in the bad environment, reducing the offset amplitude of the mounting frame, and improving the stability of the mounting frame. While the bearing frame moves inside the spherical frame, it drives the connecting rod to swing inside the support cylinder. Under the action of the counterweight, the stability of the bearing frame is improved. Under the action of the first torsion spring, when the bearing frame suddenly makes a large displacement inside the spherical frame, it plays a role in pulling the connecting rod, cooperating with the first spring to reduce the influence caused by the connecting rod driving the counterweight on the inner wall of the support cylinder in bad environment, improving the stability of the photovoltaic support, eliminating the rigid force received by the mounting frame, and avoiding damage to the mounting frame.

[0071] 3. In the present invention, the electric cylinder drives the sliding frame to move on the support frame. After the second electromagnet contacts the rotating frame, the second electromagnet is activated, and then the first electromagnet is activated. The first electromagnet drives the arc-shaped positioning frame to move towards the direction of the second electromagnet until the first electromagnet drives the arc-shaped positioning frame to contact the anti-slip protrusion. Since the bottom of the arc-shaped positioning frame has a certain elasticity and is provided with anti-slip patterns, the bottom of the arc-shaped positioning frame will deform to a certain extent after contacting the anti-slip protrusion, so that the arc-shaped positioning frame firmly presses on the anti-slip protrusion, fixing the relative positions of the fixed frame and the rotating frame. With the cooperation of the second electromagnet, the stability between the rotating frame and the fixed frame is improved.

[0072] 4. In the present invention, the air pump extracts the air in the air intake hopper through the air intake pipe. Through the settings of the mesh plate and the air filter in the air intake hopper, impurities such as dust that may be doped in the air are filtered out, and then the extracted air is transported to the inside of the mounting frame through the exhaust pipe. Then the spray head is activated to clean the dust attached to the solar panel, or the dust near the solar panel can be blown away during the process in a harsh environment, reducing the phenomenon of dust adhering to the solar panel when a harsh environment occurs, and improving the efficiency and working stability of the solar panel.

[0073] 5. In the present invention, through the setting of the limit assembly, when encountering a harsh environment, through the setting of the connecting rod, the force received by the mounting frame due to the harsh environment can be eliminated, avoiding damage to the mounting frame, and at the same time improving the stability of the mounting frame during operation, making the work of the solar panel more stable. Through the positions of the fixing assembly and the positioning part, the positions between the rotating frame and the fixed frame can be fixed more firmly and stably, avoiding the possibility of being damaged under the influence of severe and changing harsh weather. Through the setting of the dust cleaning assembly, the influence of the harsh environment on the normal operation of the solar panel is further reduced. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0087] Next, in combination with the embodiments of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present invention.

[0088] As Figures 1 to 11As shown in the figure, this embodiment proposes a biaxial tracking photovoltaic support, which includes a substrate 1, a support cylinder 2, an adjustment frame 3, a horizontal adjustment component, a limit component, an angle adjustment component, a mounting frame 4, a solar panel 5, a sensor 43 and a fixing component. The support cylinder 2 is fixedly installed on the substrate 1, and the adjustment frame 3 is fixedly installed on the top of the support cylinder 2. The horizontal adjustment component is installed inside the adjustment frame 3 and is used to adjust the horizontal position of the photovoltaic support. The horizontal adjustment component includes a spherical frame 6, a bearing frame 7, an annular plate 8, a first motor 9 and a support frame 10. The spherical frames 6 are symmetrically and fixedly installed inside the adjustment frame 3. The bearing frame 7 is slidably installed inside the spherical frame 6. An annular plate 8 is fixedly installed on the bearing frame 7. The annular plate 8 is located between the two spherical frames 6. The first motor 9 is fixedly installed inside the bearing frame 7. The support frame 10 is fixedly installed at the output end of the first motor 9. The support frame 10 is rotationally matched with the bearing frame 7.

[0089] Specifically, when using the photovoltaic support, first install the substrate 1. When the photovoltaic support is working, start the first motor 9. The first motor 9 drives the support frame 10 to rotate. The support frame 10 drives the angle adjustment component to rotate, thereby adjusting the position of the mounting frame 4 in the horizontal direction. At the same time, start the angle adjustment component to adjust the angle between the mounting frame 4 and the substrate 1. Through the setting of the sensor 43, the position of the sunlight is detected in real time, so that the solar panel 5 always faces the sun through the mounting frame 4. When encountering bad weather such as strong winds, it may affect the stability of the mounting frame 4 and even damage the mounting frame 4. At this time, it is necessary to first start the fixing component to fix the position between the angle adjustment component and the support frame 10, and then turn off and lock the first motor 9, thereby fixing the position of the support frame 10. When encountering bad weather, the bearing frame 7 will move relatively inside the spherical frame 6. At this time, under the action of the limit component, the mounting frame 4 can generate a certain displacement when affected by bad weather, thereby eliminating the rigid force received by the mounting frame 4 and avoiding damage to the mounting frame 4.

[0090] The limit component is installed on the horizontal adjustment component and is used to maintain the stability of the horizontal adjustment component during operation. The limit component includes a first spring 11, a connecting rod 12, a counterweight 13, a first coil spring 14 and a second limiting part. A plurality of first springs 11 are evenly and angularly fixedly installed at the upper and lower ends of the annular plate 8. The plurality of first springs 11 are fixedly connected to the adjustment frame 3. The connecting rod 12 is fixedly installed at the bottom of the bearing frame 7. A counterweight 13 is fixedly installed at the bottom of the connecting rod 12. The first coil spring 14 is fixedly installed between the connecting rod 12 and the support cylinder 2. The second limiting part is installed on the support cylinder 2 and is used to reduce the possibility of the connecting rod 12 rotating.

[0091] Specifically, when encountering bad weather, the bearing frame 7 will move relatively inside the spherical frame 6. The bearing frame 7 drives the annular plate 8 to shift inside the position-adjusting frame 3. At this time, the first spring 11 is compressed, thereby offsetting the force acting on the mounting frame 4 in the harsh environment, reducing the offset amplitude of the mounting frame 4, and improving the stability of the mounting frame 4. While the bearing frame 7 moves inside the spherical frame 6, it will drive the connecting rod 12 to swing inside the support cylinder 2. Under the action of the counterweight 13, the stability of the bearing frame 7 is improved. At the same time, under the action of the first torsion spring 14, the sudden force received by the mounting frame 4 can be reduced. When the bearing frame 7 suddenly undergoes a large displacement inside the spherical frame 6, it plays a role in pulling the connecting rod 12, and cooperates with the first spring 11 to reduce the impact on the inner wall of the support cylinder 2 caused by the connecting rod 12 driving the counterweight 13 in bad weather, thereby improving the stability of the photovoltaic support.

[0092] As described above, the second limiting portion includes a rotating ring 15 and a second torsion spring 16. The rotating rings 15 are symmetrically and rotatably installed inside the support cylinder 2. Second torsion springs 16 are fixedly installed inside both of the two rotating rings 15. Both of the two second torsion springs 16 are fixedly connected to the connecting rod 12, and the directions of the two second torsion springs 16 are opposite.

[0093] Specifically, when encountering a harsh environment, since the severity at different times is different, it is necessary to adjust the force between the connecting rod 12 and the second torsion spring 16 according to the severity of the harsh environment when the harsh environment occurs. At this time, the two rotating rings 15 are simultaneously driven to rotate in opposite directions. The two rotating rings 15 respectively drive the corresponding second torsion springs 16 to rotate. Since the directions of the two second torsion springs 16 are opposite, both of the two second torsion springs 16 can be wound around the connecting rod 12 while the rotating rings 15 are rotating, improving the pulling force between the second torsion spring 16 and the connecting rod 12. And due to the arrangement of the two second torsion springs 16, the connecting rod 12 is kept relatively balanced, so that when encountering bad weather, the connecting rod 12 swings with a smaller amplitude, thereby improving the stability of the mounting frame 4.

[0094] As described above, it further includes a driven bevel gear 17, a second motor 18 and a driving bevel gear 19. Driven bevel gears 17 are fixedly installed at the corresponding positions of the two rotating rings 15. The second motor 18 is fixedly installed on the support cylinder 2. The driving bevel gear 19 is fixedly installed at the output end of the second motor 18. The driving bevel gear 19 meshes with the two driven bevel gears 17.

[0095] Specifically, when driving the connecting ring to rotate, start the second motor 18. The second motor 18 drives the driving bevel gear 19 to rotate. The driving bevel gear 19 simultaneously drives the two driven bevel gears 17 to rotate in opposite directions, so that the two driven bevel gears 17 respectively drive the corresponding connecting rings to rotate.

[0096] The angle adjustment component is installed on the horizontal adjustment component and is used to adjust the angular position of the photovoltaic support. The angle adjustment component includes a fixed frame 20, a housing 21, a rotating frame 22 and a rotating part. The fixed frame 20 is fixedly installed on the support frame 10, the housing 21 is fixedly installed on the fixed frame 20, the rotating frame 22 is rotatably installed on the fixed frame 20, and the housing 21 is located inside the rotating frame 22. Among them, the rotating frame 22 is fixedly connected to the mounting frame 4, and the rotating part is installed inside the housing 21 and is used to drive the rotating frame 22 to rotate.

[0097] Specifically, when using the photovoltaic support, it is also necessary to adjust the angular position of the mounting frame 4. At this time, the rotating part drives the rotating frame 22 to rotate inside the fixed frame 20, so as to adjust the position of the mounting frame 4 according to the setting of the sensor 43.

[0098] The mounting frame 4 is fixedly installed on the angle adjustment component, the solar panel 5 is fixedly installed on the mounting frame 4, sensors 43 are fixedly installed at the four corners of the mounting frame 4. The rotating part includes a transmission shaft 23, a third motor 24, a first gear 25, a second gear 26 and a third toothed ring 27. The transmission shaft 23 is rotatably installed on the fixed frame 20, the transmission shaft 23 is located inside the housing 21, the third motor 24 is fixedly installed on the fixed frame 20, the output end of the third motor 24 is fixedly connected to the transmission shaft 23. First gears 25 are rotatably installed on both the upper and lower sides of the housing 21, a second gear 26 is fixedly installed on the transmission shaft 23, the second gear 26 meshes with the two first gears 25, the third toothed ring 27 is fixedly installed inside the rotating frame 22, and the third toothed ring 27 meshes with the two first gears 25 respectively.

[0099] Specifically, when adjusting the angular position of the mounting frame 4, start the third motor 24. The third motor 24 drives the transmission shaft 23 to rotate, the transmission shaft 23 drives the second gear 26 to rotate, the second gear 26 drives the first gear 25 to rotate, and the first gear 25 drives the third toothed ring 27 to rotate. Thus, the rotating frame 22 is driven to rotate through the third toothed ring 27 to adjust the angular position of the mounting frame 4. When it is necessary to fix the position between the rotating frame 22 and the fixed frame 20, turn off and lock the third motor 24 to fix the positions of the second gear 26 and the third toothed ring 27.

[0100] The fixing component is installed inside the angle adjustment component and is used to fix the positions of the angle adjustment component and the horizontal adjustment component when encountering harsh environments. The fixing component includes an arc-shaped positioning frame 28, anti-slip protrusions 30, a first electromagnet 31, and a positioning portion. The inside of the housing 21 is symmetrically and elastically installed inside the housing 21 through a second spring 29. A plurality of anti-slip protrusions 30 are evenly and angularly fixedly installed at positions corresponding to the arc-shaped positioning frame 28 on both sides inside the rotating frame 22. The anti-slip protrusions 30 are adapted to the arc-shaped positioning frame 28. A first electromagnet 31 is fixedly installed inside each of the two arc-shaped positioning frames 28. The positioning portion is installed on the support frame 10 and is used to control the positions of the arc-shaped positioning frame 28 and the anti-slip protrusions 30.

[0101] Specifically, when fixing the position between the rotating frame 22 and the fixed frame 20, the positioning portion is activated to move to the working position. At this time, the first electromagnet 31 is activated, and the first electromagnet 31 drives the arc-shaped positioning frame 28 to move in the direction of the positioning portion until the first electromagnet 31 drives the arc-shaped positioning frame 28 to contact the anti-slip protrusions 30. Since the bottom of the arc-shaped positioning frame 28 has a certain elasticity and is provided with anti-slip patterns, the bottom of the arc-shaped positioning frame 28 will deform to a certain extent after contacting the anti-slip protrusions 30, so that the arc-shaped positioning frame 28 firmly presses on the anti-slip protrusions 30, and the relative positions of the fixed frame 20 and the rotating frame 22 are fixed in cooperation with the positioning portion. When relative rotation is required between the fixed frame 20 and the rotating frame 22, the positioning portion is retracted and the first electromagnet 31 is turned off. At this time, the arc-shaped positioning frame 28 is pulled back into the housing 21 under the action of the second spring 29, and the arc-shaped positioning frame 28 disengages from the anti-slip protrusions 30, and the fixed frame 20 and the rotating frame 22 can be released.

[0102] As described above, the positioning portion includes a sliding frame 32, a second electromagnet 33, and an electric cylinder 34. Sliding frames 32 are slidably installed at positions corresponding to the arc-shaped positioning frame 28 on the support frame 10. Second electromagnets 33 are fixedly installed at the tops of the sliding frames 32. The second electromagnets 33 are adapted to the first electromagnet 31. The electric cylinder 34 is fixedly installed on the support frame 10, and the output end of the electric cylinder 34 is fixedly connected to the sliding frame 32.

[0103] Specifically, when fixing the position between the rotating frame 22 and the fixed frame 20, the electric cylinder 34 is activated, and the electric cylinder 34 drives the sliding frame 32 to move on the support frame 10 until the sliding frame 32 drives the second electromagnet 33 to contact the rotating frame 22. Then the second electromagnet 33 is activated, thereby fixing the position between the rotating frame 22 and the support frame 10. At the same time, in cooperation with the setting of the first electromagnet 31, the position between the rotating frame 22 and the fixed frame 20 is fixed, improving the stability between the rotating frame 22 and the fixed frame 20.

[0104] The above also includes a dust cleaning component, which includes a housing 35, an air pump 36, an air inlet hopper 37, a mesh plate 38, an air inlet pipe 39, an air filter 40, an exhaust pipe 41 and a nozzle 42. The housing 35 is fixedly installed on the support cylinder 2. The air pump 36 is fixedly installed inside the housing 35. The air inlet hopper 37 is fixedly installed on the housing 35. The mesh plate 38 is fixedly installed between the housing 35 and the air inlet hopper 37. The air inlet pipe 39 is connected between the air inlet hopper 37 and the input end of the air pump 36. The air filter 40 is fixedly installed at the position where the air inlet hopper 37 is connected to the air inlet pipe 39. Among them, the inside of the mounting frame 4 is a hollow structure. The exhaust pipe 41 is connected between the output end of the air pump 36 and the mounting frame 4. A plurality of nozzles 42 are equally angularly connected to the position of the mounting frame 4 corresponding to the solar panel 5.

[0105] Specifically, when bad weather occurs, it may bring a large amount of dust and other impurities. These impurities will adhere to the solar panel 5, affecting the normal operation of the solar panel 5 and may also affect the stability of the support frame. At this time, start the air pump 36. The air pump 36 extracts the air in the air inlet hopper 37 through the air inlet pipe 39. The air inlet hopper 37 inhales the outside air into the air inlet hopper 37 through the mesh plate 38. Through the setting of the air filter 40, the dust and other impurities that may be mixed in the air are filtered out. Then the extracted air is transported to the inside of the mounting frame 4 through the exhaust pipe 41. Then start the nozzle 42 to clean the dust on the solar panel 5, and blow the dust on the solar panel 5 outside the mounting frame 4, reducing the phenomenon of dust adhering to the solar panel 5 when bad environment occurs, and improving the efficiency and working stability of the solar panel 5.

[0106] In summary, when using the photovoltaic support, first install the substrate 1. When the photovoltaic support is working, start the first motor 9. The first motor 9 drives the support frame 10 to rotate. The support frame 10 drives the fixed frame 20 to rotate, thereby adjusting the position of the mounting frame 4 in the horizontal direction and at the same time adjusting the angular position of the mounting frame 4. When adjusting the angular position of the mounting frame 4, start the third motor 24. The third motor 24 drives the transmission shaft 23 to rotate. The transmission shaft 23 drives the second gear 26 to rotate. The second gear 26 drives the first gear 25 to rotate. The first gear 25 drives the third toothed ring 27 to rotate, thereby driving the rotating frame 22 to rotate through the third toothed ring 27 to adjust the angular position of the mounting frame 4. According to the setting of the sensor 43, the position of the sunlight is detected in real time, and the position of the mounting frame 4 is adjusted, so that the solar panel 5 always faces the sun through the mounting frame 4.

[0107] When encountering bad weather such as strong winds, it may affect the stability of the mounting frame 4 and even damage the mounting frame 4. At this time, start the electric cylinder 34. The electric cylinder 34 drives the sliding frame 32 to move on the support frame 10 until the sliding frame 32 drives the second electromagnet 33 to contact the rotating frame 22. Then start the second electromagnet 33, and then start the first electromagnet 31. The first electromagnet 31 drives the arc-shaped positioning frame 28 to move towards the direction of the second electromagnet 33 until the first electromagnet 31 drives the arc-shaped positioning frame 28 to contact the anti-slip protrusion 30. Since the bottom of the arc-shaped positioning frame 28 has a certain elasticity and is provided with anti-slip lines, the bottom of the arc-shaped positioning frame 28 will deform to a certain extent after contacting the anti-slip protrusion 30, so that the arc-shaped positioning frame 28 firmly presses on the anti-slip protrusion 30, fixing the relative positions of the fixed frame 20 and the rotating frame 22 and improving the stability between the rotating frame 22 and the fixed frame 20.

[0108] Then turn off and lock the first motor 9 to fix the position of the support frame 10. When encountering bad weather, the bearing frame 7 will move relatively inside the spherical frame 6. The bearing frame 7 drives the annular plate 8 to offset inside the positioning frame 3. At this time, the first spring 11 is compressed, thereby offsetting the force acting on the mounting frame 4 in the harsh environment, reducing the offset amplitude of the mounting frame 4 and improving the stability of the mounting frame 4. While the bearing frame 7 moves inside the spherical frame 6, it will drive the connecting rod 12 to swing inside the support cylinder 2. Under the action of the counterweight 13, the stability of the bearing frame 7 is improved. At the same time, under the action of the first coil spring 14, the sudden force on the mounting frame 4 can be reduced. When the bearing frame 7 suddenly undergoes a large displacement inside the spherical frame 6, it plays a role in pulling the connecting rod 12, and cooperates with the first spring 11 to reduce the impact on the inner wall of the support cylinder 2 caused by the connecting rod 12 driving the counterweight 13 in bad weather, improving the stability of the photovoltaic support.

[0109] Due to the different intensities at different times, when a harsh environment occurs, it is necessary to adjust the force between the connecting rod 12 and the second coil spring 16 according to the intensity of the harsh environment. At this time, the second motor 18 is started, and the second motor 18 drives the active bevel gear 19 to rotate. The active bevel gear 19 simultaneously drives the two driven bevel gears 17 to rotate in opposite directions, so that the two driven bevel gears 17 respectively drive the corresponding connecting rings to rotate, and the two rotating rings 15 respectively drive the corresponding second coil springs 16 to rotate. Since the directions of the two second coil springs 16 are opposite, the two second coil springs 16 can be wound around the connecting rod 12 while the rotating ring 15 rotates, improving the tensile force between the second coil spring 16 and the connecting rod 12. And due to the arrangement of the two second coil springs 16, the connecting rod 12 is kept relatively balanced, so that when encountering harsh weather, the connecting rod 12 swings with a smaller amplitude, eliminating the rigid force received by the mounting bracket 4 and avoiding damage to the mounting bracket 4, thereby improving the stability of the mounting bracket 4.

[0110] When relative rotation is required between the fixing frame 20 and the rotating frame 22, the electric cylinder 34 is retracted, and the first electromagnet 31 and the second electromagnet 33 are turned off. At this time, the arc-shaped positioning frame 28 is pulled back into the interior of the housing 21 under the action of the second spring 29, and the arc-shaped positioning frame 28 is disengaged from the anti-slip protrusion 30, so that the fixing frame 20 and the rotating frame 22 can be loosened.

[0111] When a harsh weather occurs, a large amount of dust and other impurities may be brought. These impurities will adhere to the solar panel 5, affecting the normal operation of the solar panel 5 and may also affect the stability of the support frame. At this time, the air pump 36 is started. The air pump 36 extracts the air in the air inlet hopper 37 through the air inlet pipe 39. The air inlet hopper 37 inhales the outside air into the interior of the air inlet hopper 37 through the mesh plate 38. Through the setting of the air filter 40, the dust and other impurities that may be doped in the air are filtered out, and then the extracted air is conveyed to the interior of the mounting bracket 4 through the exhaust pipe 41. Then the spray head 42 is started to clean the dust on the solar panel 5, and the dust on the solar panel 5 is blown out of the mounting bracket 4, reducing the phenomenon of dust adhering to the solar panel 5 when a harsh environment occurs and improving the efficiency and stability of the solar panel 5 during operation.

[0112] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
