Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic support equipment, and in particular to photovoltaic wind-resistant support equipment and a support method. Background Art

[0002] Photovoltaic wind-resistant support equipment usually refers to the support structure for installing photovoltaic panels. Currently common photovoltaic support structure styles include fixed supports, tracking supports and fixed adjustable supports.

[0003] Chinese patent CN113890464B discloses a wind-resistant integrated photovoltaic bracket and its installation method. By setting a buffer part, when strong wind blows the photovoltaic panel to shake, the photovoltaic panel drives the mounting seat to rotate on the crossbeam, so that the inclined rod pushes the slider to slide inside the arc seat. In the absence of strong wind influence, the spring can support the inclination angle of the photovoltaic panel and will not change significantly. When the wind is strong, the spring can be deformed by force, causing the photovoltaic panel to flip over, thereby reducing the wind-exposed area of ​​the photovoltaic panel.

[0004] In order to improve the utilization rate of solar energy, more and more photovoltaic brackets are currently using tracking brackets and fixed adjustable brackets. These two types of photovoltaic brackets can adjust the inclination angle of the photovoltaic panel according to the angle of sunlight, thereby increasing power generation. The buffer parts provided in the above-mentioned devices can improve the wind resistance of the photovoltaic panel, but cannot adjust the inclination angle of the photovoltaic panel. At the same time, when the above-mentioned devices encounter strong winds, the photovoltaic panels will swing at a large angle due to the strong wind with constantly changing wind speeds, which can easily lead to rapid structural loss in the photovoltaic bracket, thereby affecting the service life of the photovoltaic bracket.

[0024] (3) Beneficial effects

[0025] Compared with the prior art, the present invention provides a photovoltaic wind-resistant support device and support method, which has the following beneficial effects:

[0026] 1. The photovoltaic wind-resistant support equipment is equipped with a wind-resistant mechanism. In windless conditions, it can support the beam so that the inclination angle of the beam remains unchanged. When there is a small wind force, the swing caused by the wind blowing the photovoltaic panel is transmitted to the buffer spring through the arc frame and the tooth plate, thereby reducing the swing frequency of the photovoltaic panel. When there is a strong wind, the locking rod is inserted into the mounting block, so that the pin in the mounting block is pushed into the support, so that the beam and the support are fixed and locked, so that the strong wind cannot blow the photovoltaic panel to rotate, thereby improving the wind resistance of the photovoltaic wind-resistant support equipment.

[0027] 2. The photovoltaic wind-resistant support equipment, by arranging transmission teeth on the arc frame, not only meshes and transmits with the flat gear in the angle adjustment mechanism, but also meshes and fixes with the tooth plate in the buffer and shock-absorbing component. Therefore, it is more convenient to control the rotation and fixation of the arc frame. Moreover, when affected by a smaller wind force, the arc frame can drive the tooth plate to rotate, thereby facilitating the expansion and contraction of the buffer spring for buffering.

[0028] 3. The photovoltaic wind-resistant support equipment is equipped with a bidirectional screw rod, a threaded slider, a slide plate and a directional slider, so that the bottom of the connecting rod can only move up and down when it is raised or lowered, and cannot swing, thereby limiting the range of motion of the tooth plate when pushed by the arc frame, reducing the swing amplitude of the photovoltaic panel when the wind is relatively small, and through the drive shaft, the active bevel gear, the driven bevel gear and the locking drive motor, the beams installed on the supports at both ends of the photovoltaic wind-resistant support equipment can rotate and be fixed synchronously.

[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0050] Example 1

[0051] See also Figure 1 、 Figure 2 、 Figure 4 and Figure 7 The present invention provides a photovoltaic wind-resistant support device, comprising a support 1, a beam 2, and a support rod 3. The middle position of the lower surface of the beam 2 is rotatably connected to the top of the support 1, the lower surface of the support rod 3 is fixedly connected to the upper surface of the beam 2, an arc frame 4 is fixedly installed on the lower surface of the beam 2, a transmission tooth 41 is provided on the outer side surface of the arc frame 4, and a locking rod 42 is fixedly connected between the arc frame 4 and the beam 2;

[0052] The support 1 is equipped with an angle adjustment mechanism 5 and a wind-resistant mechanism 6. The angle adjustment mechanism 5 is used to drive the crossbeam 2 to rotate around the top of the support 1. The wind-resistant mechanism 6 includes a buffering and shock-absorbing component 61, a locking component 62 and a locking driving component 63. The buffering and shock-absorbing component 61 includes a tooth plate 611 and a buffer spring 612. The upper end of the tooth plate 611 is provided with a tooth block, which is adapted to mesh with the transmission tooth 41. The tooth plate 611 is movably installed in the interior of the support 1 through the buffer spring 612. The locking component 62 includes a latch 621, a return spring 622 and a mounting block 623. The blocks 623 are fixedly mounted on both ends of the lower surface of the tooth plate 611, and the latch 621 is slidably mounted inside the mounting blocks 623. The lower end of the locking rod 42 is engaged with the mounting blocks 623, and the upper end of the latch 621 is engaged with the lower end of the locking rod 42, and the lower end of the latch 621 is engaged with the support 1. The return spring 622 is mounted between the mounting blocks 623 and the latch 621, and is used to separate the latch 621 from the support 1 after the latch 621 is separated from the locking rod 42. The locking drive component 63 is mounted on the support 1, and is used to drive the tooth plate 611 to move up and down;

[0053] An interlocking mechanism 7 is also provided on the crossbeam 2 , and the interlocking mechanism 7 is used to connect the crossbeams 2 of adjacent photovoltaic wind-resistant support devices.

[0054] As can be seen from the above, when using the support device, the support 1 is fixed to the ground, and the photovoltaic panels are fixedly installed side by side on the support pole 3; the working mode of the angle adjustment mechanism 5 is set according to the lighting conditions of the area where the photovoltaic wind-resistant support device is installed to control the inclination angle of the beam 2 at different times; when the photovoltaic panel encounters a small wind and vibrates, the vibration is transmitted to the buffer spring 612 through the arc frame 4 and the tooth plate 611, thereby reducing the impact of the wind on the photovoltaic panel. When the photovoltaic panel encounters strong winds, the angle adjustment mechanism 5 drives the beam 2 to move, so that the beam 2 is horizontal, and the locking component 62 locks the beam 2, which reduces the wind-exposed area of ​​the photovoltaic panel while preventing the photovoltaic panel from shaking. At the same time, multiple photovoltaic wind-resistant support devices in the same row can be connected through the interlocking mechanism 7 to improve the wind resistance. By setting up the wind-resistant mechanism 6, under windless conditions, the tooth plate 611 is close to the arc frame 4 through the locking drive component 63, and is fixed by the buffer spring 612, so that the tooth plate 611 can fix the arc frame 4, thereby enabling the buffer shock-absorbing component 61 to support and fix the beam 2, so that the inclination angle of the beam 2 remains unchanged. When there is a small wind force, the swing generated by the wind blowing the photovoltaic panel is transmitted to the buffer spring 612 through the arc frame 4 and the tooth plate 611, and the vibration buffering of the buffer spring 612 reduces the swing frequency of the photovoltaic panel. When there is a strong wind, by inserting the locking rod 42 into the mounting block 623, the pin 621 in the mounting block 623 is pushed into the support 1, so that the beam 2 and the support 1 are fixed and locked, so that the strong wind cannot blow the photovoltaic panel to rotate, thereby improving the wind resistance of the photovoltaic wind-resistant support equipment.

[0055] Example 2

[0056] like Figure 2 - Figure 8 As shown, the difference between this embodiment and the above embodiment is that the support 1 includes an oblique rod 11, a mounting plate 12, a mounting shaft 13 and a support leg 14. The oblique rod 11 is symmetrically fixed on both sides of the mounting plate 12, and the mounting shaft 13 is fixedly installed on the top of the mounting plate 12. A bearing 21 is fixedly installed in the middle position of the lower surface of the beam 2, and the bearing 21 is rotatably installed on the mounting shaft 13. The support leg 14 is fixedly installed at the lower end of the oblique rod 11, and the adjacent oblique rods 11 are fixedly installed on the transverse rib 15. The support 1 also includes a transverse rod 16, and a support seat 17 is fixedly installed at the lower end of the transverse rod 16.

[0057] As can be seen from the above, the support 1 is relatively stable through the arrangement of the inclined rod 11 , the mounting plate 12 , the mounting shaft 13 and the supporting foot 14 .

[0058] The buffering and shock-absorbing component 61 includes a connecting rod 613, the upper end of the connecting rod 613 is fixedly connected to the middle position of the lower surface of the tooth plate 611, and the lower end of the connecting rod 613 is installed on the locking drive component 63, and the buffer spring 612 is arranged on both sides of the connecting rod 613, and the two ends of the buffer spring 612 are respectively rotatably connected to the inner wall of one side of the support seat 17 and one side surface of the connecting rod 613.

[0059] As can be seen from the above, by providing the connecting rod 613 , the buffer spring 612 does not need to extend from the interior of the support seat 17 when supporting the tooth plate 611 .

[0060] A through hole 18 is formed in the middle of the crossbar 16 , and the connecting rod 613 is inserted into the through hole 18 . The length of the through hole 18 is greater than the width of the connecting rod 613 .

[0061] As can be seen from the above, by providing the through-hole 18 , the connecting rod 613 can not only slide inside the through-hole 18 , but also rotate relative to the through-hole 18 .

[0062] A slot 624 is provided on the upper surface of the mounting block 623 at a position opposite to the locking rod 42, and a through hole 625 is provided at the lower end of the slot 624, which passes through the bottom wall of the slot 624 and extends to the lower surface of the mounting block 623. The latch 621 is slidably inserted into the interior of the through hole 625, and a stopper 626 is fixedly installed on the upper end of the latch 621. The two ends of the return spring 622 are respectively fixedly connected to the bottom wall of the slot 624 and the lower surface of the stopper 626. A limit block 627 is symmetrically fixed on one side of the cross bar 16, and a socket 628 is provided on the limit block 627, which is adapted to be plugged into the latch 621.

[0063] As can be seen from the above, when the arc frame 4 rotates so that the locking rod 42 is opposite to the mounting block 623, the tooth plate 611 moves upward to enable the locking rod 42 to be inserted into the slot 624 opened on the mounting block 623, so that the pin 621 can be inserted into the socket 628, so that the axes of the locking rod 42, the mounting block 623, the pin 621 and the socket 628 are connected in a straight line, and under the restriction of the mounting block 623, the locking rod 42 cannot be rotated out, and the tooth plate 611 cannot be rotated, thereby fixing the arc frame 4 and the beam 2.

[0064] The locking drive component 63 includes a bidirectional screw rod 631, a threaded slider 632, a slide plate 633 and a directional slider 634. The two ends of the bidirectional screw rod 631 are respectively rotatably connected to the two side walls of the support seat 17, the threaded slider 632 is respectively threadedly connected to the two sides of the bidirectional screw rod 631, the two ends of the slide plate 633 are respectively slidably connected to the two side walls of the support seat 17, and the middle position of the upper surface of the slide plate 633 is rotatably connected to the lower end of the connecting rod 613, the directional slider 634 is fixedly installed in the middle of the lower surface of the slide plate 633, and two symmetrical rotating blocks 635 are rotatably installed on the directional slider 634, and the other end of the rotating block 635 is rotatably connected to the threaded slider 632 on the same side.

[0065] As can be seen from the above, when the bidirectional screw 631 rotates, the two threaded sliders 632 slide in opposite directions at the same speed, and the directional slider 634 moves up and down through the push of the turning block 635. Since the slide plate 633 is slidably installed on the support seat 17, the directional slider 634 moves up and down, driving the slide plate 633 to move up and down, causing the lower end of the connecting rod 613 to move up and down, thereby pushing the tooth plate 611 to move up and down.

[0066] The locking drive component 63 also includes a driving shaft 636, a driving bevel gear 637, a driven bevel gear 638 and a locking drive motor 639. The driving shaft 636 is rotatably connected to the outer wall of one side of the support seat 17. The driving bevel gear 637 is fixedly mounted on the driving shaft 636. The driven bevel gear 638 is fixedly mounted on one end of the bidirectional screw rod 631, and the driven bevel gear 638 is meshed with the driving bevel gear 637. The locking drive motor 639 is placed on the inner side of the support 1, and the locking drive motor 639 is fixedly mounted on the cement pier fixed to the ground. The locking drive motor 639 and the driving shaft 636 are connected through a transmission pulley.

[0067] As can be seen from the above, the beams 2 installed on the supports 1 at both ends of the photovoltaic wind-resistant support equipment are driven by the drive shaft 636, the active bevel gear 637 and the driven bevel gear 638, and the transmission synchronization is better.

[0068] Example 3

[0069] like Figure 2 As shown, the difference between this embodiment and the above embodiment is that the angle adjustment mechanism 5 includes a rotating shaft 51, a flat gear 52 and an angle adjustment motor 53. The rotating shaft 51 is rotatably connected to a side wall of the inclined rod 11, and the flat gear 52 is fixedly mounted on the rotating shaft 51. The angle adjustment motor 53 is placed on the inner side of the support 1, and the angle adjustment motor 53 is fixedly mounted on a cement pier fixed to the ground. The angle adjustment motor 53 is connected to the rotating shaft 51 through a transmission pulley.

[0070] The rotation of the flat gear 52 can drive the arc frame 4 to rotate. In this embodiment, the angle adjustment motor 53 and the rotating shaft 51 are single-headed transmission, that is, the rotor of the angle adjustment motor 53 can drive the rotating shaft 51 to rotate, while the rotating shaft 51 cannot drive the rotor of the angle adjustment motor 53 to rotate, so that the arc frame 4 will not be restricted by the flat gear 52 when swinging.

[0071] Example 4

[0072] like Figure 3 and Figure 5 As shown, the difference between this embodiment and the above embodiment is that the interlocking mechanism 7 includes a sleeve 71, an insert plate 72, a sleeve 73, a driving gear 74 and an interlocking driving motor 75. The sleeve 71 is fixedly mounted on the beam 2 on one side, and the length direction of the sleeve 71 is perpendicular to the length direction of the beam 2. The insert plate 72 is slidably mounted inside the sleeve 71, the sleeve 73 is fixedly mounted on the beam 2 away from the sleeve 71, and the opening direction of the sleeve 73 is opposite to the sliding direction of the insert plate 72. A tooth groove 76 is provided on one side of the insert plate 72, and a notch 77 is provided on one side of the sleeve 71. The driving gear 74 is rotatably mounted on one of the beams 2, and it extends through the notch 77 to the interior of the sleeve 71 and is meshed with the tooth groove 76. The interlocking driving motor 75 is fixedly mounted on the beam 2, and its driving end is fixedly connected to the driving gear 74.

[0073] As can be seen from the above, when the plug 72 on a photovoltaic wind-resistant support device extends from the sleeve 71, the plug 72 can be inserted into the socket 73 on the adjacent photovoltaic wind-resistant support device, so that the two adjacent photovoltaic wind-resistant support devices can be connected and fixed.

[0074] Example 5

[0075] See also Figure 1 - Figure 8 The present invention also discloses a photovoltaic wind-resistant support method, which comprises the following specific steps:

[0076] Fix the support 1 to the ground and install the photovoltaic panels side by side on the support pole 3;

[0077] According to the light conditions of the area where the photovoltaic wind-resistant support equipment is installed, the working mode of the angle adjustment mechanism 5 is set to control the tilt angle of the beam 2 at different times;

[0078] When the photovoltaic panel vibrates due to a small wind, the vibration is transmitted to the buffer spring 612 through the arc frame 4 and the tooth plate 611, thereby reducing the impact of the wind on the photovoltaic panel. When the photovoltaic panel encounters strong wind, the angle adjustment mechanism 5 drives the beam 2 to move, so that the beam 2 is horizontal, and the locking component 62 locks the beam 2, thereby reducing the wind-exposed area of ​​the photovoltaic panel and preventing the photovoltaic panel from shaking. At the same time, multiple photovoltaic wind-resistant support devices in the same row can be connected through the interlocking mechanism 7 to improve the wind resistance performance.

[0079] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
