Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation, and in particular to a solar tracking device based on a photovoltaic power generation system. Background Art

[0002] A photovoltaic power generation system uses the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. In a photovoltaic power generation system, in order to increase the length of time that sunlight shines on the solar panels, solar tracking devices are generally used to make the solar panels rotate according to the position of the sun, thereby improving power generation efficiency. A single-axis tracker is a type of solar tracking device. People use single-axis trackers to adjust the tilt angle of photovoltaic panels in photovoltaic power generation systems.

[0003] In order to prevent the photovoltaic panel from rotating due to external forces (such as wind and gravity) when its motor stops working or the power is accidentally cut off, existing single-axis trackers generally use a worm gear transmission mechanism to accurately adjust the tilt angle of the photovoltaic panel. However, long-term use of the worm gear will cause the tooth surface to wear, which will lead to an increase in the meshing clearance and affect the accuracy of the transmission precision.

At the same time, the U-shaped stirring magnetic plate rotates to absorb the ferromagnetic metal particles generated by the wear between the worm gear and worm that enter the lubricating oil tank through the smear roller, thereby extending the service life of the lubricating oil.

[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments. Figures 1-11 In the present invention, a solar tracking device based on a photovoltaic power generation system includes: an adjustment box 2 fixedly mounted on a mounting base plate 1, a solar panel 6 and an adjustment mechanism for adjusting the angle of the solar panel 6 are provided on the adjustment box 2, and a driving mechanism for driving a worm gear 8 to rotate is provided inside the adjustment box 2;

[0035] The driving mechanism includes a dual-axis motor 12 fixedly mounted in the regulating box 2, and a first bevel gear 13 is fixedly mounted on the two output shafts of the dual-axis motor 12, and the two first bevel gears 13 are respectively meshed with two second bevel gears 15 fixedly mounted on the vertical rods 14. The two vertical rods 14 are both rotatably connected to the regulating box 2, and the two vertical rods 14 are respectively provided with precision mechanisms for precisely meshing the worm 16 with the worm wheel 8. The two vertical rods 14 are respectively provided with two alarm mechanisms for sounding the alarm when the gap between the worm wheel 8 and the worm 16 becomes larger. A lubrication mechanism for conveying lubricating oil to the worm wheel 8 and the worm 16 is provided in the regulating box 2. In order to transmit the alarm sound to the outside world, a sound transmission hole is opened on the outer wall of one side of the regulating box 2, and a dust-proof sponge is provided in the sound transmission hole to prevent external dust from entering the regulating box 2.

[0036] In order to adjust the angle of the solar panel 6 and thereby improve the power generation efficiency of the solar panel 6, the adjustment mechanism includes an upper rotating rod 3 and a lower rotating rod 10 rotatably installed in the adjustment box 2. A worm gear 8 and two moving gears 11 are fixedly sleeved on the lower rotating rod 10, and the two moving gears 11 are respectively engaged with the residual gears 7 fixedly sleeved on the two upper rotating rods 3. Both ends of the upper rotating rod 3 extend to the outside of the adjustment box 2 and are fixedly installed with a U-shaped plate 4. The upper rotating rod 3 is fixedly connected to the U-shaped plate 4 by welding, and the U-shaped plate 4 is fixedly connected to the solar panel 6 through the connecting plate 5.

[0037] In order to ensure that the worm 16 is always in close contact with the worm wheel 8 when the transmission teeth of the worm wheel 8 and the worm 16 wear and tear, resulting in a decrease in the meshing precision, thereby improving the transmission accuracy, the precision mechanism includes a cavity 19 opened on the vertical rod 14, and a limit plate 18 is slidably installed in the cavity 19. In order to enable the vertical rod 14 to rotate, the limit plate 18 can be driven to rotate. Limit grooves are respectively opened in the two cavities 19, and the two sides of the two limit plates 18 extend into the two limit grooves and are respectively slidably connected to the inner walls of the two limit grooves. The top of the limit plate 18 is rotatably installed with a vertical rod 17, and the top of the vertical rod 17 extends to the vertical rod 14 and is fixedly installed with the worm 16. A tension spring 21 is movably sleeved on the vertical rod 17, and the top of the tension spring 21 is fixedly connected to the top inner wall of the cavity 19. The bottom end of the tension spring 21 is fixedly connected to the limit plate 18. Fixed connection, two first pull ropes 20 are fixedly installed on the bottom of the limit plate 18, and both ends of the two first pull ropes 20 extend to the outside of the vertical rod 14 and are fixedly installed with weight balls 22. A first guide cross bar is fixedly installed in the cavity 19, and the first guide cross bar is slidably connected with the two first pull ropes 20. The first pull ropes 20 are guided by the first guide cross bar. When the vertical rod 14 rotates, it drives the weight ball 22 to make a circular motion with the center of the vertical rod 14. The weight ball 22 is pulled downward by the centrifugal force of the external force, and the downward movement of the first pull rope 20 drives the limit 18, the vertical rod 17 and the worm 16 to move downward. In this way, when the transmission teeth of the worm wheel 8 and the worm 16 are worn and the meshing precision is reduced, the worm 16 is always in close contact with the worm wheel 8, thereby improving the transmission accuracy.

[0038] In order to remind people to replace the worm gear 8 and the worm 16 in time when the gap between the worm gear 8 and the worm 16 is too large, the alarm mechanism includes a semicircular conductive plate 23 fixedly mounted on the weight ball 22 and an L-shaped plate 24 fixedly mounted on the vertical rod 14. A conductive sheet 25, an alarm 26, and a battery 28 are fixedly mounted on the L-shaped plate 24. The conductive sheet 25 is electrically connected to the negative pole of the alarm 26 through a first wire, and the positive pole of the alarm 26 is electrically connected to the negative pole of the battery 28 through a second wire. The positive pole of the battery 28 is electrically connected to the semicircular conductive plate 23 through the spiral wire 27. When the gap between the worm wheel 8 and the worm 16 is too large, the worm 16 and the first pull rope 20 move downward a longer distance, and the weight ball 22 is further away from the vertical rod 14, driving the semicircular conductive plate 23 to contact the conductive sheet 25, thereby forming a complete electrical circuit with the conductive sheet 25, the first wire, the alarm 26, the second wire, the battery 28, the spiral wire 27 and the semicircular conductive plate 23, and the alarm 26 sounds an alarm.

[0039] In order to reduce the wear of the worm gear 8 and worm 16 and improve its service life, the lubrication mechanism includes a lubricating oil tank 32 fixedly installed on the inner wall of the bottom of the adjusting box 2 through two vertical plates and a fixed sleeve arranged on the lower rotating rod 10 with two eccentric wheels 30, and the top of the lubricating oil tank 32 is in an open state. A smear roller 35 is rotatably installed in the lubricating oil tank 32, and the smear roller 35 is in contact with the worm gear 8. A frame frame 29 is slidingly sleeved on the two eccentric wheels 30, and a second pull rope 31 is fixedly installed on the bottom of the two frame frames 29, and a frame-shaped rubber sealing plate 36 is fixedly installed on the bottom end of the two second pull ropes 31. When the lower rotating rod 10 rotates, the eccentric wheel 30 is driven to rotate, and the eccentric wheel 30 drives the frame frame 29 in the first half of its rotation cycle. The frame 29 moves upward, and the frame frame 29 moves upward, driving the second pull rope 31 to move upward. The second pull rope 31 moves upward, driving the frame rubber sealing plate 36 to move upward and no longer squeezes the smear roller 35. At this time, the worm gear 8 rotates and drives the smear roller 35 to rotate through friction to continuously apply the lubricating oil in the lubricating oil tank 32 to the worm gear 8 and the worm 16, thereby improving the service life of the worm gear 8 and the worm 16. Two upper fixed blocks and two lower fixed blocks are fixedly installed on the outer walls of both sides of the lubricating oil tank 32, and guide rods 33 are respectively slidably installed on the two upper fixed blocks, and the top ends of the two guide rods 33 are fixedly connected to the frame rubber sealing plate 36, and the bottom ends of the two guide rods 33 are respectively fixedly installed with elastic pull ropes 3 4, and the two elastic pull ropes 34 are fixedly connected to the two lower fixed blocks respectively, a winding rod 38 is rotatably installed in the lubricating oil tank 32, and the bottom end of the winding rod 38 extends to the outside of the lubricating oil tank 32 and is fixedly sleeved with a circular plate 39, two third pull ropes 37 are wound around the winding rod 38, and the top ends of the two third pull ropes 37 are fixedly connected to the frame-shaped rubber sealing plate 36, two second guide cross bars are fixedly installed in the lubricating oil tank 32, and the two second guide cross bars are slidably connected to the two third pull ropes 37 respectively, and the third pull ropes 37 are limited and guided by the second guide cross bars to prevent the third pull ropes 37 from contacting the smear roller 35 and affecting the normal rotation of the smear roller 35, and a U-shaped stirring magnetic plate is fixedly installed on the top of the winding rod 38 41. At the same time, the frame-shaped rubber sealing plate 36 moves upward, driving the third pull rope 37 to move upward. The third pull rope 37 moves upward and pulls the winding rod 38 to rotate through friction. The rotation of the winding rod 38 drives the U-shaped stirring magnetic plate 41 to rotate to stir the lubricating oil, so that the overall viscosity of the lubricating oil in the lubricating oil tank 32 remains at the same state, thereby improving the lubrication effect. At the same time, the U-shaped stirring magnetic plate 41 rotates to adsorb the ferromagnetic metal particles generated by the wear between the worm wheel 8 and the worm 16 that enter the lubricating oil tank 32 through the coating roller 35, thereby extending the service life of the lubricating oil. The distance between the U-shaped stirring magnetic plate 41 and the dual-axis motor 12 is a safe distance, so the U-shaped stirring magnetic plate 41 will not affect the operation of the dual-axis motor 12.

[0040] In order to allow the frame-shaped rubber sealing plate 36 to rotate and reel in the third pull rope 37 when it moves downward, and thereby drive the U-shaped stirring magnetic plate 41 to rotate when the frame-shaped rubber sealing plate 36 moves upward, a second torsion spring 40 is provided on the movable sleeve of the winding rod 38, and the bottom end of the second torsion spring 40 is fixedly connected to the circular plate 39, and the top end of the second torsion spring 40 is fixedly connected to the bottom of the lubricating oil tank 32.

[0041] In order to make the moving gear 11 rotate until it no longer meshes with the residual gear 7, drive the residual gear 7 to return to its original position, and then drive the solar panel 6 to return to its original angle to face the morning sunlight, which is convenient for people to use next time, two first torsion springs 9 are movably sleeved on the upper rotating rod 3, and one end of the two first torsion springs 9 is fixedly connected to the two residual gears 7 respectively, and the other ends of the two first torsion springs 9 are fixedly connected to the inner walls on both sides of the adjustment box 2.

[0042] In order to limit the frame 29 so that the frame 29 is always stably slidably installed on the eccentric wheel 30, limiting grooves are respectively provided on the inner walls of the four sides of the frame 29, and one end of the eccentric wheel 30 extends into the corresponding limiting groove and is slidably connected to the inner wall of the corresponding limiting groove.

[0043] The working principle of the solar tracking device based on the photovoltaic power generation system provided by the present invention is as follows; in the initial state, the semicircular conductive plate 23 is not in contact with the conductive sheet 25, the lubricating oil tank 32 is filled with lubricating oil, and the elastic pull rope 34 is in a stretched state. The elastic pull rope 34 is used to make the frame-shaped rubber sealing plate 36 and the coating roller 35 in close contact, blocking the opening of the lubricating oil tank 32 to prevent the lubricating oil from evaporating. The mounting base 1 is fixedly installed in a specific location through an external fixing screw so that sunlight is irradiated on the solar panel 6 to generate electricity. When the position of the sun changes, the dual-axis motor 12 is started, and the rotation of the dual-axis motor 12 drives the first bevel gear 13 to rotate, and the rotation of the first bevel gear 13 drives the second bevel gear 15 to rotate, and the second bevel gear 15 rotates. Drive the vertical rod 14 to rotate, the vertical rod 14 rotates to drive the limit plate 18, the vertical rod 17 and the worm 16 to rotate, the worm 16 rotates to drive the worm gear 8 to rotate, the worm gear 8 rotates to drive the lower rotating rod 10 and the moving gear 11 to rotate, the moving gear 11 rotates to drive the residual gear 7 to rotate, the residual gear 7 rotates to drive the upper rotating rod 3 to rotate, the upper rotating rod 3 rotates to drive the U-shaped plate 4 to rotate and at the same time change the first torsion spring 9 from a free state to a stressed state, the U-shaped plate 4 rotates and then drives the solar panel 6 to rotate, so that the solar panel 6 always faces the sun, thereby improving the power generation efficiency of the solar panel 6. When the sun just sets, the moving gear 11 rotates to no longer mesh with the residual gear 7. At this moment, under the action of the first torsion spring 9, the residual gear 7 is driven to return to its initial position, thereby driving the solar panel 6 is restored to its original angle facing the morning sun, which is convenient for people to use next time. At the same time, when the vertical rod 14 rotates, it drives the weight ball 22 to make a circular motion with the center of the vertical rod 14. The weight ball 22 is pulled downward by the centrifugal force of the external force to pull the first pull rope 20. The downward movement of the first pull rope 20 drives the limit plate 18, the vertical rod 17 and the worm 16 to move downward. In this way, when the transmission teeth of the worm wheel 8 and the worm 16 wear and cause the meshing precision to decrease, the worm 16 is always in close contact with the worm wheel 8, thereby improving the transmission accuracy. When the gap between the worm wheel 8 and the worm 16 is too large, the worm 16 and the first pull rope 20 move downward a longer distance, and the weight ball 22 is further away from the vertical rod 14, driving the semicircular conductive plate 23 and the conductive sheet 2 5 contacts, thereby forming a complete electrical circuit among the conductive sheet 25, the first wire, the alarm 26, the second wire, the battery 28, the spiral wire 27 and the semicircular conductive plate 23. The alarm 26 sounds an alarm to remind people to replace the worm gear 8 and the worm 16 in time. At the same time, when the lower rotating rod 10 rotates, it drives the eccentric wheel 30 to rotate. The first half cycle of the rotation of the eccentric wheel 30 drives the frame 29 to move upward. The upward movement of the frame 29 drives the second pull rope 31 to move upward. The upward movement of the second pull rope 31 drives the frame-shaped rubber sealing plate 36 to move upward and no longer squeezes the smear roller 35. At this moment, the worm gear 8 rotates, and the friction force drives the smear roller 35 to rotate, so that the lubricating oil in the lubricating oil tank 32 is continuously applied to the worm gear 8 and the worm 16.This increases the service life of the worm gear 8 and worm 16. Simultaneously, the upward movement of the frame-shaped rubber sealing plate 36 drives the third pull rope 37 upward. The upward movement of the third pull rope 37 rotates the winding rod 38 through friction. The rotation of the winding rod 38 drives the U-shaped stirring magnetic plate 41 to stir the lubricating oil, maintaining the overall viscosity of the lubricating oil in the lubricating oil tank 32 at a constant level, improving the lubrication effect. Simultaneously, the rotation of the U-shaped stirring magnetic plate 41 absorbs ferromagnetic metal particles generated by wear between the worm gear 8 and worm 16 that enter the lubricating oil tank 32 through the smear roller 35, thereby extending the service life of the lubricating oil.

[0044] Compared with related technologies, the solar tracking device based on the photovoltaic power generation system provided by the present invention has the following beneficial effects:

[0045] The present invention provides a solar tracking device based on a photovoltaic power generation system. An elastic pull rope 34 is used to tightly contact a frame-shaped rubber sealing plate 36 with a coating roller 35 to block the opening of a lubricating oil tank 32, preventing lubricating oil from evaporating. A dual-axis motor 12 rotates the solar panel 6, ensuring that the solar panel 6 always faces the sunlight, thereby improving power generation efficiency. When the sun sets, the moving gear 11 rotates until it no longer meshes with the residual gear 7. At this point, the first torsion spring 9 returns to its original state, driving the solar panel 6 back to its original angle, facing the morning sunlight, making it easier for people to use it next time.

[0046] When the vertical rod 14 rotates, the weight ball 22 is subjected to the centrifugal force of the external force, so that the worm 16 always maintains a downward movement trend and is in close contact with the worm wheel 8. In this way, when the transmission teeth of the worm wheel 8 and the worm 16 wear and cause the meshing precision to decrease, the worm 16 is still in close contact with the worm wheel 8, thereby improving the transmission accuracy.

[0047] When the gap between the worm wheel 8 and the worm 16 is too large, the weight ball 22 moves further away from the vertical rod 14 and drives the semicircular conductive plate 23 to contact the conductive sheet 25, so that the conductive sheet 25, the first wire, the alarm 26, the second wire, the battery 28, the spiral wire 27 and the semicircular conductive plate 23 form a complete electrical circuit. The alarm 26 sounds an alarm and the worm wheel 8 and the worm 16 are replaced in time.

[0048] When the lower rotating rod 10 rotates, it drives the eccentric wheel 30 to rotate in the first half cycle, so that the frame-shaped rubber sealing plate 36 moves upward and no longer squeezes the smear roller 35. At this time, the worm gear 8 rotates and drives the smear roller 35 to rotate through friction to continuously apply the lubricating oil in the lubricating oil tank 32 to the worm gear 8 and the worm 16, thereby improving the service life of the worm gear 8 and the worm 16. At the same time, the frame-shaped rubber sealing plate 36 moves upward and drives the U-shaped stirring magnetic plate 41 to rotate to stir the lubricating oil, so that the overall viscosity of the lubricating oil remains at the same state, thereby improving the lubrication effect. At the same time, the U-shaped stirring magnetic plate 41 rotates to absorb the ferromagnetic metal particles generated by the wear between the worm gear 8 and the worm 16 that enter the lubricating oil tank 32 through the smear roller 35, thereby extending the service life of the lubricating oil.
