[0002] The development of new energy sources is in full swing, and a new energy revolution is sweeping the globe. Solar photovoltaic power generation technology is favored by people for its convenient energy conversion, mature technology, intuitiveness, and high efficiency. In particular, the centralized and distributed photovoltaic power generation methods that are now being widely promoted are gradually being applied to people's production and life under the support and encouragement of the national new energy development policy.

[0003] As a crucial component of photovoltaic power generation technology, photovoltaic panels primarily function to receive sunlight. To enhance their ability to absorb light energy, they are typically mounted on a rotating shaft using screws and nuts, allowing them to rotate as the sun moves. However, these screws and nuts make it inconvenient for workers to disassemble and replace the panels, resulting in a cumbersome process. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the prior art: the screw and nut fasteners make it inconvenient for workers to disassemble and replace the photovoltaic panels, and the process is quite cumbersome. Therefore, this invention proposes a photovoltaic power generation single-axis tracking power transmission and strong wind damping integrated device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A photovoltaic power generation single-axis tracking power transmission and strong wind damping integrated device includes two towers, with a rotating shaft rotatably installed between the two towers, and the rotating shaft is controlled to rotate by a drive component;

[0007] A photovoltaic panel is provided at the rotating shaft, and two connecting rods are fixedly installed on the lower surface of the photovoltaic panel. A slider is fixedly installed at the bottom end of the connecting rods.

[0008] The rotating shaft is equipped with two sets of locking components, which are used to lock the two sliders respectively. Each locking component includes a mounting block fixedly installed on the surface of the rotating shaft, two first spring rods, and two triangular locking plates. The surface of the mounting block has a sliding opening for the slider to be inserted. The mounting block has symmetrically opened mounting cavities. The two first spring rods are horizontally fixedly installed in the two mounting cavities respectively. The cavity wall of the mounting cavity has a through-hole communicating with the sliding opening. One end of the two first spring rods passes through the two through-holes and is fixedly connected to the two locking plates respectively. A triangular pressing block is fixedly installed on the surface of the slider. The front and rear surfaces of the slider have locking grooves for the two locking plates to enter. The first spring rods are controlled to retract by a transmission component.

[0009] A contact plate is fixedly installed on the surface of the tower. A soil entry cone is fixedly installed on the lower surface of the contact plate. A placement cavity is formed inside the soil entry cone. A vertical plate is fixedly installed at the bottom of the placement cavity. Two airbags are fixedly installed on both the front and rear surfaces of the vertical plate. A second spring rod is horizontally fixedly installed inside each airbag. Multiple openings communicating with the placement cavity are formed on the surface of the soil entry cone. Fastening nails are fixedly installed on the surface of each airbag away from the vertical plate. One end of each fastening nail is located within one of the multiple openings. Multiple airbags collect air through a gas collecting assembly. The gas collecting assembly includes a fan blade, a force-bearing rod, and multiple sealed third spring rods. A first fixing rod and a second fixing rod are vertically fixedly installed on the surface of the contact plate. The fan blade and the force-bearing rod are respectively... The device is rotatably connected to the first and second fixed rods. A telescopic spring is fitted on the second fixed rod. The two ends of the telescopic spring are fixedly connected to the force-bearing rod and the contact plate, respectively. An annular frame with the soil-penetrating cone as its center is fixedly installed on the upper surface of the contact plate. Two support plates are fixedly installed inside the annular frame. Multiple third spring rods are fixedly installed on the left and right surfaces of the two support plates, each with the soil-penetrating cone as its center. An air inlet pipe and an air outlet pipe are fixedly installed on the surface of the third spring rods. Multiple air outlet pipes are connected to multiple airbags. A one-way valve is provided in both the air inlet pipe and the air outlet pipe. Two abutment rods are fixedly installed on the lower surface of the force-bearing rod. An air outlet hole is opened in the wall of the airbag. The diameter of the air outlet hole is smaller than the diameter of the air outlet pipe.

[0010] Preferably, the transmission assembly includes a push plate fixedly sleeved on the first spring rod, and the upper surface of the mounting block has two movable openings that are respectively connected to two mounting cavities, with the top ends of the two push plates respectively protruding through the two movable openings.

[0011] Preferably, a geared motor is fixedly installed on the surface of one of the towers, one end of the rotating shaft extends out of the tower, and a transmission roller is fixedly sleeved on both the output shaft and the rotating shaft of the geared motor, and a belt is wound around the two transmission rollers.

[0012] Preferably, the surface of the mounting block is provided with two sets of limiting components, and the two sets of limiting components are respectively used to limit the movement of the two push plates.

[0013] Preferably, the limiting component includes two mounting plates fixedly installed on the surface of the mounting block and an L-shaped rotating rod. A rotating rod is rotatably installed between the two mounting plates. The rotating rod is fixedly sleeved on the rotating rod. A limiting opening for pushing the plate in is opened on the surface of the rotating rod away from the rotating rod. Two torsion springs are sleeved on the rotating rod. The two ends of the torsion springs are fixedly connected to the mounting plate and the rotating rod, respectively.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] The installation and removal of the photovoltaic panel and the rotating shaft can be completed quickly and easily by using two sets of locking components, avoiding the tedious steps of using screws and nuts to fix the panel and improving the efficiency of replacing the photovoltaic panel.

[0016] When installing the tower, the entry cone is first inserted into the ground for fixation. When encountering strong winds, multiple airbags will quickly collect air and push multiple fastening nails into the soil, making the entry cone form a cross shape in the soil. This enhances the entry cone's grip and prevents the tower from being pulled out of the soil by strong winds. When the wind weakens, the multiple fastening nails will gradually move back into the installation cavity, making it easier for subsequent workers to pull the entry cone out of the soil and move the device to a different position.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Reference Figure 1-8 A photovoltaic power generation single-axis tracking power transmission and strong wind damping integrated device includes two towers 1, a rotating shaft 2 rotatably installed between the two towers 1, the rotating shaft 2 is controlled to rotate by a drive component, a contact plate 22 is fixedly installed on the surface of the tower 1, a soil entry cone 23 is fixedly installed on the lower surface of the contact plate 22, a reduction motor 15 is fixedly installed on the surface of one of the towers 1, one end of the rotating shaft 2 passes through the tower 1, and a transmission roller 16 is fixedly sleeved on both the output shaft of the reduction motor 15 and the rotating shaft 2, and a belt 17 is wound on the two transmission rollers 16;

[0028] A photovoltaic panel 3 is provided at the rotating shaft 2. Two connecting rods 4 are fixedly installed on the lower surface of the photovoltaic panel 3, and a slider 5 is fixedly installed at the bottom of the connecting rods 4.

[0029] Two sets of locking components are provided on the rotating shaft 2. The two sets of locking components are used to lock the two sliders 5 respectively. The locking components include a mounting block 6 fixedly installed on the surface of the rotating shaft 2, two first spring rods 7 and two triangular locking plates 8. The surface of the mounting block 6 is provided with a sliding opening 9 for the slider 5 to be inserted. The mounting block 6 is provided with symmetrical mounting cavities 10. The two first spring rods 7 are fixedly installed horizontally in the two mounting cavities 10 respectively. The cavity wall of the mounting cavity 10 is provided with a through opening that communicates with the sliding opening 9. One end of the two first spring rods 7 passes through the two through openings and is fixedly connected to the two locking plates 8 respectively. A triangular pressing block 11 is fixedly installed on the surface of the slider 5. The front and rear surfaces of the slider 5 are provided with locking grooves 12 for the two locking plates 8 to enter. The first spring rods 7 are controlled to retract by a transmission component. The transmission component includes a push plate 13 fixedly sleeved on the first spring rod 7. The upper surface of the mounting block 6 is provided with two moving openings 14 that communicate with the two mounting cavities 10 respectively. The top ends of the two push plates 13 pass through the two moving openings 14 respectively.

[0030] When the geared motor 15 is started, the rotating shaft 2 will rotate together with the photovoltaic panel 3, which is locked to itself by the locking component, under the transmission action of the transmission roller 16 and the belt 17. This allows the photovoltaic panel to rotate with the movement of the sun, improving the photovoltaic panel 3's ability to receive light energy.

[0031] During installation, the two ground-penetrating cones 23 are first inserted into the ground for fixation. Then, the two sliders 5 are aligned with the two sliding openings 9 and pushed in. The inclined surfaces of the two locking plates 8 located in the sliding openings 9 will slide into contact with the two inclined surfaces of the pressing block 11. Under the pressure of the inclined surfaces, the two first spring rods 7 will retract until the sliders 5 slide to the two locking grooves 12 on the front and rear surfaces, which correspond to the positions of the two locking plates 8. At this time, the locking plates 8 will quickly reset under the elastic potential energy of the first spring rods 7 and enter the locking grooves 12 to form a lock. In this way, the installation between the photovoltaic panel 3 and the rotating shaft 2 is completed. When it is necessary to disassemble the photovoltaic panel 3, simply push the multiple push plates 13 by hand to move them and control the multiple first spring rods 7 to retract, so that the multiple locking plates 8 can be moved out of the multiple locking grooves 12 respectively.

[0032] The surface of the mounting block 6 is provided with two sets of limiting components. The two sets of limiting components are used to limit the movement of the two push plates 13. The limiting components include two mounting plates 18 fixedly mounted on the surface of the mounting block 6 and an L-shaped rotating rod 19. A rotating rod 20 is rotatably mounted between the two mounting plates 18. The rotating rod 19 is fixedly sleeved on the rotating rod 20. The surface of the rotating rod 19 away from the rotating rod 20 has a limiting opening for the push plate 13 to enter. Two torsion springs 21 are sleeved on the rotating rod 20. The two ends of the torsion springs 21 are fixedly connected to the mounting plate 18 and the rotating rod 19 respectively.

[0033] When installing the photovoltaic panel 3, multiple rotating rods 19 need to be manually controlled to rotate, so that multiple push plates 13 move out of multiple restricting ports respectively. After the photovoltaic panel 3 is installed, the multiple rotating rods 19 are released. The rotating rods 19 will quickly rotate and reset under the elastic potential energy of the torsion spring 21. At this time, the multiple push plates 13 will re-enter the multiple restricting ports respectively. The multiple push plates 13 cannot move at this time, so the multiple first spring rods 7 cannot move at this time, to avoid the first spring rods 7 being contracted by the influence of external forces, causing the photovoltaic panel 3 to detach from the rotating shaft 2.

[0034] An insertion cone 23 has a placement cavity 24. A vertical plate 25 is fixedly installed at the bottom of the placement cavity 24. Two airbags 26 are fixedly installed on the front and rear surfaces of the vertical plate 25. A second spring rod 27 is horizontally fixedly installed inside the airbag 26. The surface of the insertion cone 23 has multiple openings that communicate with the placement cavity 24. Fastening nails 28 are fixedly installed on the surface of the airbags 26 away from the vertical plate 25. One end of the fastening nails 28 is located in one of the multiple openings. Multiple airbags 26 collect air through an air collecting assembly, which includes a fan blade 29, a force-bearing rod 39, and multiple sealed third spring rods 30. A first fixing rod 31 and a second fixing rod 32 are vertically fixedly installed on the surface of the contact plate 22. The fan blade 29 and the force-bearing rod 39 are rotatably sleeved on the first fixing rod 31 and the second fixing rod 32, respectively. A telescopic spring 33 is sleeved on the second fixing rod 32. The force rod 39 and the contact plate 22 are fixedly connected respectively. The upper surface of the contact plate 22 is fixedly installed with an annular frame 34 centered on the soil entry cone 23. Two support plates are fixedly installed inside the annular frame 34. Multiple third spring rods 30 are fixedly installed on the left and right surfaces of the two support plates respectively, and all are centered on the soil entry cone 23. An air inlet pipe 35 and an air outlet pipe 36 are fixedly installed on the surface of the third spring rod 30. Multiple air outlet pipes 36 are connected to multiple air bags 26 respectively. One-way valves are provided in both the air inlet pipe 35 and the air outlet pipe 36. The one-way valve in the air inlet pipe 35 is directed to enter the third spring rod 30 from the outside. The one-way valve in the air outlet pipe 36 is directed to enter the air bag 26 from the third spring rod 30. Two abutment rods 37 are fixedly installed on the lower surface of the force rod 39. An air outlet hole 38 is opened in the wall of the air bag 26. The diameter of the air outlet hole 38 is smaller than the diameter of the air outlet pipe 36.

[0035] When the device encounters strong winds, the multiple fan blades 29 will rotate rapidly under the force of the wind. During this rotation, they will strike the multiple force-bearing rods 39. The force-bearing rods 39 will then reciprocate with small amplitude rotation in cooperation with the fan blades 29 and the telescopic springs 33. At this time, the multiple abutment rods 37 will also strike the ends of the multiple third spring rods 30 rapidly. The third spring rods 30 will contract upon impact, thus reducing their internal volume and increasing their pressure. The gas inside will then enter the air bladder 26 through the air outlet pipe 36. Then, when the third spring rods 30 return to their original position under their own elastic potential energy, their internal volume will increase and their pressure will decrease. The gas from the outside will enter the air bladder 26 through the air intake pipe 35. As this process continues, the gas inside the air bladder 26 will increase. Since the diameter of the air outlet 38 is smaller than the diameter of the air outlet pipe 36, the gas entering the air bladder 26 will be much more than the gas leaving through the air outlet 38. The air bladder 26 will then gradually stretch, and the second spring rod 27 inside the air bladder 26 will also stretch. At this time, multiple fastening nails 28 will be inserted into the soil from multiple openings, making the soil entry cone 23 cross-shaped in the soil. This will enhance the grip of the soil entry cone 23 and prevent the tower 1 from being pulled out of the soil due to strong winds.

[0036] When the wind weakens or disappears, the fan blades 29 stop rotating, so no more gas will enter the airbag 26. The gas inside the airbag 26 will be gradually squeezed out of the air outlet 38 under the elastic potential energy of the second spring rod 27. Then, as the airbag 26 recovers, the fastening nail 28 will gradually move back to the installation cavity 24, making it easier for the staff to pull the soil entry cone 23 out of the soil and move the position of the device.

[0037] In this invention, when installing the photovoltaic panel 3, the two sliders 5 are first aligned with the two sliding holes 9 and pushed in. The two first spring rods 7 will then retract until the sliders 5 slide to the position of the two locking grooves 12 on the front and rear surfaces, which correspond to the positions of the two locking plates 8. At this time, the locking plates 8 will enter the locking grooves 12 to form a lock. In this way, the installation between the photovoltaic panel 3 and the rotating shaft 2 is completed. When it is necessary to disassemble the photovoltaic panel 3, multiple sets of transmission components are used to control the retraction of multiple first spring rods 7, so that multiple locking plates 8 can be moved out of multiple locking grooves 12 respectively. This is convenient and quick, avoids the cumbersome steps of using screws and nuts for fastening, and improves the work efficiency of replacing the photovoltaic panel 3.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
