DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example 1: Please refer to Figure 1-Figure 6 , a photovoltaic support device with wind resistance function shown in the figure comprises: a base 1 and a support frame 2 standing on the top of the base 1, and two photovoltaic panels 5 are installed on the side of the support frame 2 away from the base 1, and the photovoltaic panels 5 are placed at an angle;

[0030] It also includes: a turning unit, which is used to adjust the horizontal direction of the support frame 2 and the photovoltaic panel 5, and the turning unit is arranged inside the base 1;

[0031] The folding unit is used to fold the two photovoltaic panels 5 together to reduce the wind-exposed area. The folding unit is located between the support frame 2 and the two photovoltaic panels 5 .

[0032] The turning unit includes a turntable 9 rotatably mounted inside the base 1, and the bottom of the support frame 2 is fixedly assembled with the turntable 9, a sleeve 10 is fixedly arranged at the bottom of the turntable 9, and a worm gear 11 is fixedly sleeved on the outer surface of the sleeve 10, a rotating shaft 13 is laterally rotatably mounted inside the base 1, and a worm 12 movably meshed with the worm gear 11 is fixedly sleeved on the outer surface of the rotating shaft 13, the rotating shaft 13 extends out of the outside of the base 1, and the worm gear 12 is rotated by the rotating shaft 13, and the worm gear 11 and the turntable 9 are driven to rotate by the worm gear 12.

[0033] The sleeve 10 and the rotating disk 9 are coaxially distributed, and the axis of the rotating shaft 13 is perpendicular to the axis of the sleeve 10 .

[0034] The folding unit includes an assembly frame block 3 fixedly mounted on the top of the support frame 2. The outer side of the assembly frame block 3 is hingedly equipped with two symmetrically distributed installation frames 4. The two installation frames 4 are respectively fixedly connected to two photovoltaic panels 5. A reinforcement plate 21 is fixedly arranged between the installation frame 4 and the photovoltaic panel 5 on the same side. A trigger component is arranged between each reinforcement plate 21 and the support frame 2. The reinforcement plate 21 can improve the stability between the photovoltaic panel 5 and the installation frame 4.

[0035] The triggering component includes a gear differential 15 fixedly mounted inside the support frame 2, and a threaded rod 16 is fixedly arranged at the output end of the gear differential 15, and the end of the threaded rod 16 away from the gear differential 15 faces the assembly frame block 3, and the external thread sleeve of the threaded rod 16 is provided with a threaded sleeve block 17, and the outer side of the threaded sleeve block 17 is fixedly provided with two symmetrically distributed fixed rods 18, and the two fixed rods 18 are slidably extended out of the support frame 2, and each reinforcement plate 21 is fixedly provided with a hinged seat block 20 on one end surface away from the photovoltaic panel 5, and each fixed rod 18 is provided with a straight groove 2 at one end away from the threaded sleeve block 17. 2, and a connecting rod 19 is hingedly provided between the straight groove 22 and the hinged seat block 20 on the same side, and a limit rod 14 is fixedly installed on the inner coaxial line of the base 1, and the limit rod 14 movably runs through the sleeve 10, the turntable 9 and the support frame 2, and the end of the limit rod 14 away from the base 1 is connected to the input end of the gear differential 15. Since the limit rod 14 is fixed, when the turntable 9 rotates with the support frame 2, it is equivalent to the input end of the gear differential 15 rotating. The gear differential 15 is a speed increaser, that is, when the input end of the gear differential 15 rotates one circle, its output end can rotate multiple circles.

[0036] Working principle: The staff can set up multiple photovoltaic devices on the roof of the building, and the multiple photovoltaic devices are placed in parallel, so that the rotating shafts 13 inside the multiple bases 1 can be docked together. By rotating the rotating shafts 13 manually or electrically, multiple sets of worms 12 and worm wheels 11 can be driven. At this time, the turntable 9 will deflect the support frame 2 and the upper photovoltaic panel 5. The purpose of the deflection is to prevent the photovoltaic panel 5 from being directly opposite to the wind direction of the strong wind, which can effectively reduce the impact of the strong wind on the photovoltaic panel 5;

[0037] Moreover, during the deflection of the support frame 2, since the limit rod 14 is fixed, it is equivalent to that the input end of the gear differential 15 is started, so that the output end of the gear differential 15 rotates multiple circles with the threaded rod 16. Through the threaded assembly of the threaded sleeve 17 and the threaded rod 16, and the limiting of the fixed rod 18 and the support frame 2, the fixed rod 18 can move upward, and the two photovoltaic panels 5 can be pushed upward through the connecting rod 19, so that the two photovoltaic panels 5 can be closed together, and the glass panels of the two photovoltaic panels 5 can be protected from collision by foreign objects.

[0038] Example 2: Please refer to Figure 6 and Figure 8 This embodiment is a further explanation of the first embodiment. A limiting sleeve 25 is arranged between the input end of the gear differential 15 and the limiting rod 14. The input end of the gear differential 15, the limiting rod 14 and the limiting sleeve 25 are coaxially distributed, and a clamping assembly is arranged between the input end of the gear differential 15 and the limiting sleeve 25. The clamping assembly can avoid the limiting rod 14 and the gear differential 15 from getting stuck.

[0039] The engaging assembly includes a movable disk body 24 fixedly arranged at the input end of the gear differential 15, and the movable disk body 24 is rotatably assembled inside the limiting sleeve 25. The inner wall of the limiting sleeve 25 is provided with a plurality of arc grooves 27 equidistantly distributed around the circumference. At least two radially distributed chucks 28 are slidably arranged inside the movable disk body 24. The end of the chuck 28 away from the center of the movable disk body 24 is fixedly provided with a dome brake column 23 sliding through the movable disk body 24, and a spring 26 is arranged between the other end of the chuck 28 and the movable disk body 24. The dome top head of the spring 26 is movably engaged with the arc groove 27. When there is a large torsional force between the movable disk body 24 and the limiting sleeve 25, the dome brake column 23 will be separated from the inside of the arc groove 27. At this time, the limiting sleeve 25 cannot rotate with the input end of the gear differential 15 through the movable disk body 24.

[0040] One end of the limiting rod 14 away from the base 1 is embedded in the limiting sleeve 25, and the limiting rod 14 and the limiting sleeve 25 are fixed by bolts.

[0041] In this embodiment: when the threaded rod 16 drives the threaded sleeve 17 to move upward, and the two photovoltaic panels 5 are pushed closer to each other through the action of the fixed rod 18 and the connecting rod 19, the closure of the two photovoltaic panels 5 causes the threaded sleeve 17 to be unable to move. At this time, the limiting rod 14 drives the limiting sleeve 25 to rotate, which can generate a large torsional force between the limiting sleeve 25 and the movable disk 24. At this time, the dome brake column 23 can be separated from the arc groove 27, and the limiting sleeve 25 can be idle, which can prevent the two photovoltaic panels 5 from being damaged by a large extrusion force, thereby protecting the photovoltaic panels 5.

[0042] Example 3: Please refer to Figure 1 This embodiment is a further explanation of the first embodiment. A column 6 is fixedly mounted at the top center of the assembly frame block 3, and a rotating rod 7 is rotatably sleeved at the end of the column 6. The column 6 is the mid-perpendicular line of the rotating rod 7, and bowl-shaped blocks 8 are fixedly mounted at both ends of the rotating rod 7. The two bowl-shaped blocks 8 are distributed at equal intervals around the circumference. The two bowl-shaped blocks 8 can be pushed by the flow of air, so that the entire rotating rod 7 rotates at the end of the column 6.

[0043] The bowl-shaped block 8 is made of silicone rubber. When the bowl-shaped block 8 is clamped by two photovoltaic panels 5 , it will not cause damage to the glass panel of the photovoltaic panel 5 .

[0044] In this embodiment: During normal use of the photovoltaic panel 5, in order to prevent birds from stopping on the photovoltaic panel 5 and defecating, causing the excrement to coat the photovoltaic panel 5 and affect the electrical conversion efficiency, the gas flowing in the air can blow the bowl-shaped block 8 during normal use, so that the bowl-shaped block 8 can rotate continuously with the rotating rod 7, and the rotation process can drive away the birds and prevent them from stopping.
