DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figures 1 to 7 As shown, the utility model provides a photovoltaic support that is easy to adjust, including columns 1, wherein there are two groups of columns 1, and support columns 2 are arranged on the tops of the two groups of columns 1, and inclined beams 3 are rotatably installed on the tops of the support columns 2, and a cross beam 4 is fixedly installed between the two groups of inclined beams 3;

[0028] An adjusting rod 5 is fixedly installed at the bottom of the two groups of inclined beams 3, and slots 9 are opened on the front and rear sides of the two groups of support columns 2. The adjusting rod 5 passes through the slot 9 and is movably installed inside the support column 2. A tooth 6 is fixedly opened at the bottom of the adjusting rod 5. Gears 7 are rotatably installed inside the two groups of support columns 2, and the two groups of gears 7 are fixedly connected by a synchronization rod 8, and the gear 7 and the tooth 6 are meshed with each other;

[0029] A fixed cylinder 17 is fixedly installed on the outer wall of the support column 2 on the left side, and a braking mechanism is arranged inside the fixed cylinder 17. One end of the braking mechanism is fixedly connected to the gear 7. A control disk 19 is rotatably installed on the left side of the fixed cylinder 17, and two sets of control rods 20 are fixedly installed on the right side of the control disk 19.

[0030] The staff first installs the photovoltaic bracket. After the installation is completed, when the laying angle of the photovoltaic module needs to be adjusted, the staff can rotate the control disk 19 clockwise or counterclockwise. When the control disk 19 rotates clockwise, the control rod 20 moves synchronously with the control disk 19, and at this time, the front control rod 20 will squeeze the protrusion on the surface of the slider 12, so that the slider 12 slides inward, and the spring 13 is squeezed by the slider 12, further disengaging the brake block 2 15 and the ratchet ring 2 18. At the same time, the rear control rod 20 will drive the slider 12 to move, and due to the characteristics of the ratchet ring 16, when the slider 12 moves, the brake block 14 cannot brake the ratchet ring 16. At this time, the fixed plate 11 drives the rotating disk 10 clockwise. Rotate to make the gear 7 rotate. At this time, through the transmission of the synchronization rod 8, the two sets of gears 7 drive the adjustment rod 5 to rotate through the teeth 6, so that the inclination angle of the inclined beam 3 changes. When the staff rotates the control disk 19 counterclockwise, the rear control rod 20 will squeeze the surface protrusion of the slider 12, so that the brake block 14 and the ratchet ring 16 are disengaged, and the brake block 2 15 of the front slider 12 cannot brake the ratchet ring 2 18, further making the gear 7 rotate counterclockwise, which is convenient for adjusting the photovoltaic bracket. After the adjustment is completed, the brake block 14 and the ratchet ring 16 are meshed with each other, and the brake block 2 15 and the ratchet ring 2 18 are meshed with each other, so that the ratchet ring 16 and the ratchet ring 2 18 brake the gear 7 to avoid changes in the support angle of the photovoltaic bracket.

[0031] By rotating the control disk 19, the control rod 20 will drive the fixed plate 11 to rotate. At this time, the rotating disk 10 drives the gear 7 to rotate, and further the gear 7 drives the adjusting rod 5 to rotate through the teeth 6. At this time, the supporting surface angle of the photovoltaic bracket changes, and after the adjustment is completed, the ratchet ring 16 and the ratchet ring 2 18 brake the gear 7 through the brake block 14 and the brake block 2 15. Compared with the traditional device, the device controls the rotation of the gear 7 through the control disk 19, and can easily adjust the inclination angle of the inclined beam 3. The inclination angles of the two groups of inclined beams 3 are the same, which improves the stability of the photovoltaic module. The gear 7 is braked through the braking mechanism to avoid shaking of the photovoltaic module, which reduces the difficulty of operation for the staff.

[0032] Among them, an extension rod 21 is fixedly installed at the bottom of the support column 2, and a hole 22 is opened inside the extension rod 21. The extension rod 21 is movably installed inside the column 1. A fastener 23 is provided on the outer wall of the column 1. The fastener 23 and the column 1 are threadedly connected. One end of the fastener 23 passes through the outer wall of the column 1 and is located inside the hole 22 to fix the hole 22.

[0033] When the staff is installing the photovoltaic bracket, the staff lifts the support column 2 upwards so that the inclined beam 3 on the top of the support column 2 is at a suitable height. The staff then rotates the fastener 23 so that one end of the fastener 23 passes through the column 1 and is located inside the hole 22. At this time, the support column 2 is fixed.

[0034] By setting the extension rod 21 and the hole 22 inside the extension rod 21, the staff can adjust the support height of the support column 2, and after the adjustment is completed, the extension rod 21 is fixed by the fastener 23. Compared with the traditional device, the device extends the support height of the support column 2 through the setting of the extension rod 21, thereby improving the versatility of the device.

[0035] The braking mechanism includes a rotating disk 10 rotatably mounted inside a fixed cylinder 17 . The rotating disk 10 is rotatably mounted on the outer wall of the support column 2 , one end of which is fixedly connected to the gear 7 . A fixed plate 11 is fixedly mounted on the left side of the rotating disk 10 .

[0036] The braking mechanism further includes a ratchet ring 16 fixedly mounted on the inner wall of the fixed tube 17 , and a ratchet ring 2 18 is fixedly mounted on the left side of the ratchet ring 16 .

[0037] A sliding groove is provided inside the fixing plate 11 , and sliders 12 are slidably installed on both the front and rear sides of the fixing plate 11 , and one end of two groups of the sliders 12 and the fixing plate 11 are elastically connected via springs 13 .

[0038] After the adjustment is completed, the elastic potential energy of the spring 13 will drive the brake block 14 and the brake block 2 15 outward, so that the brake block 14 and the brake block 2 15 respectively conflict with the ratchet ring 16 and the ratchet ring 2 18 to achieve the braking of the gear 7.

[0039] Among them, there are two groups of sliders 12, and the slider 12 on the rear side is fixedly connected to brake block 14, and brake block 14 and ratchet ring 16 are engaged with each other. The slider 12 on the front side is fixedly connected to brake block 2 15, and brake block 2 15 and ratchet ring 2 18 are engaged with each other.

[0040] After the adjustment is completed, brake block 14 and ratchet ring 16 are meshed with each other, and brake block 2 15 and ratchet ring 2 18 are meshed with each other, so that ratchet ring 16 and ratchet ring 2 18 brake the gear 7 to prevent the supporting angle of the photovoltaic bracket from changing.

[0041] The two groups of sliders 12 are internally fixed with protrusions, and the protrusions are in the shape of right triangles, and the inclined surfaces of the protrusions of the two groups of sliders 12 are opposite.

[0042] When the control disk 19 rotates clockwise, the control rod 20 moves synchronously with the control disk 19, and at this time, the front control rod 20 will squeeze the protrusion on the surface of the slider 12, causing the slider 12 to slide inward. When the staff rotates the control disk 19 counterclockwise, the rear control rod 20 will squeeze the protrusion on the surface of the slider 12, causing the brake block 14 and the ratchet ring 16 to disengage.

[0043] The working principle and use process of this utility model:

[0044] The staff first installs the photovoltaic bracket. After the installation is completed, when the laying angle of the photovoltaic module needs to be adjusted, the staff can rotate the control disk 19 clockwise or counterclockwise. When the control disk 19 rotates clockwise, the control rod 20 moves synchronously with the control disk 19, and at this time, the front control rod 20 will squeeze the protrusion on the surface of the slider 12, so that the slider 12 slides inward, and the spring 13 is squeezed by the slider 12, further disengaging the brake block 2 15 and the ratchet ring 2 18. At the same time, the rear control rod 20 will drive the slider 12 to move, and due to the characteristics of the ratchet ring 16, when the slider 12 moves, the brake block 14 cannot brake the ratchet ring 16. At this time, the fixed plate 11 drives the rotating disk 10 clockwise. Rotate to make the gear 7 rotate. At this time, through the transmission of the synchronization rod 8, the two sets of gears 7 drive the adjustment rod 5 to rotate through the teeth 6, so that the inclination angle of the inclined beam 3 changes. When the staff rotates the control disk 19 counterclockwise, the rear control rod 20 will squeeze the surface protrusion of the slider 12, so that the brake block 14 and the ratchet ring 16 are disengaged, and the brake block 2 15 of the front slider 12 cannot brake the ratchet ring 2 18, further making the gear 7 rotate counterclockwise, which is convenient for adjusting the photovoltaic bracket. After the adjustment is completed, the brake block 14 and the ratchet ring 16 are meshed with each other, and the brake block 2 15 and the ratchet ring 2 18 are meshed with each other, so that the ratchet ring 16 and the ratchet ring 2 18 brake the gear 7 to avoid changes in the support angle of the photovoltaic bracket.

[0045] When the staff is installing the photovoltaic bracket, the staff lifts the support column 2 upwards so that the inclined beam 3 on the top of the support column 2 is at a suitable height. The staff then rotates the fastener 23 so that one end of the fastener 23 passes through the column 1 and is located inside the hole 22. At this time, the support column 2 is fixed.
