Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic panel installation accessories, and specifically relates to a photovoltaic panel installation structure. Background Art

[0002] A photovoltaic panel is the abbreviation of a solar photovoltaic panel, also called a solar panel. It is a device that directly or indirectly converts solar radiation into electrical energy by using the photovoltaic effect or the photochemical effect. Generally, it consists of a bottom plate, solar cells, a light-transmitting cover plate, and a metal edge seal. Since the power generation of a single solar photovoltaic panel is limited, in order to improve the power generation efficiency and power generation amount, multiple solar photovoltaic panels are usually used. When installing solar photovoltaic panels, a base is usually built using stainless steel or aluminum alloy brackets in a relatively open area, and then a fastener is used to press the metal edge seal of the solar photovoltaic panel, and then the fastener and the bracket are fixed using bolts.

[0003] In the prior art, the fasteners are usually made of aluminum alloy, and are divided into single fasteners and double fasteners. The single fastener can only press one solar photovoltaic panel, and the double fastener can press two adjacent solar photovoltaic panels at the same time. In order to reduce the installation gap and improve the space utilization rate, usually a single fastener is used for the outer side edge of the outermost solar photovoltaic panel, and double fasteners are used between the inner solar panels. However, during the maintenance and replacement of the photovoltaic panels, the fasteners on both sides of the photovoltaic panels need to be removed. At this time, only one side of the adjacent photovoltaic panels has a fastener for fixation. To prevent the adjacent photovoltaic panels from sliding due to the reduction of fasteners caused by replacing the photovoltaic panels, the bolts of the fasteners are usually tightened relatively tightly, which is likely to damage the photovoltaic panels. In addition, when disassembling the fasteners, the operator needs to step on the edge of the photovoltaic panel to reach the fixing screws of the fasteners, which is likely to damage the intact photovoltaic panel, resulting in unnecessary losses.

[0030] Embodiment 1:

[0031] Please refer to Figures 1-4, the above technical solution of the present utility model is described in detail through the following embodiments:

[0032] A photovoltaic panel installation structure, comprising:

[0033] A photovoltaic panel 1, the photovoltaic panel 1 includes a photovoltaic cell 11, and the outside of the photovoltaic cell 11 is wrapped with a sealing edge 12.

[0034] The sealing edge 12 is made of aluminum alloy material and is used to protect the photovoltaic cell 11, and the photovoltaic cell 11 is used to convert light energy into electrical energy.

[0035] An installation frame 2, the installation frame 2 includes a cross beam 23, and the upper part of the cross beam 23 is fixedly connected to the sealing edge 12 through a top fastener 3 and a bottom fastener 4;

[0036] The installation frame 2 further includes a column 21, and the bottom of the column 21 is inserted into the bottom surface or fixed with concrete. The top of the column 21 is fixedly installed with a longitudinal beam 22 through bolts, and the cross beam 23 is fixedly installed on the top surface of the longitudinal beam 22 through bolts. The column 21 and the longitudinal beam 22 are used to bear the weight of the cross beam 23, and the cross beam 23 is used to bear the weight of the photovoltaic panel 1.

[0037] An installation groove 24 is provided inside the cross beam 23, and an opening is provided on the side of the cross beam 23 away from the photovoltaic panel 1.

[0038] The cross beam 23 is made of aluminum alloy material. The installation groove 24 penetrates through both ends of the cross beam 23.

[0039] The top fastener 3 includes a first U-shaped plate 31, the first U-shaped plate 31 is slidably connected to the cross beam 23 through a first fastener, and a C-shaped fastener 36 is connected to the side of the first U-shaped plate 31 close to the photovoltaic panel 1 through a first adjustment assembly. The bottom surface of the head of the C-shaped fastener 36 abuts against the inner bottom surface of the head of the sealing edge 12. The first U-shaped plate 31 wraps the left and right two side surfaces and the bottom surface of the cross beam 23.

[0040] The first adjustment assembly is used to adjust the distance between the bottom surface of the head of the C-shaped fastener 36 and the inner bottom surface of the head of the sealing edge 12. When the bottom surface of the head of the C-shaped fastener 36 abuts against the inner bottom surface of the head of the sealing edge 12, it can cooperate with the cross beam 23 to clamp the sealing edge 12, and fix the sealing edge 12 by using friction to prevent the sealing edge 12 from sliding down, thereby preventing the photovoltaic panel 1 from moving.

[0041] The first fastener includes a first bolt 33, the screw rod of the first bolt 33 penetrates through the first U-shaped plate 31 and is threadedly connected to a first slider 32 through an opening on the side surface of the cross beam 23, and the first slider 32 can slide in the installation groove 24.

[0042] Since the first bolt 33 is threadedly connected to the first slider 32, rotating the first bolt 33 can drive the first slider 32 to move along the axis direction of the first bolt 33, thereby controlling the distance between the first slider 32 and the inner side wall of the cross beam 23.

[0043] When the first slider 32 abuts against the inner wall of the cross beam 23, the first U-shaped plate 31 cooperates to clamp the cross beam 23 to realize the fixation of the first U-shaped plate 31.

[0044] When the first slider 32 separates from the inner wall of the cross beam 23, the first U-shaped plate 31 can slide along the cross beam 23.

[0045] The first adjustment component includes an adjustment stud 34, which is vertically welded and installed in the middle of the bottom surface of the first U-shaped plate 31. The adjustment stud 34 penetrates downward through the bottom of the C-shaped fastener 36, and an adjustment nut 35 is threadedly connected between the C-shaped fastener 36 and the first U-shaped plate 31 on the adjustment stud 34.

[0046] Since the adjustment nut 35 is threadedly connected to the adjustment stud 34, rotating the adjustment nut 35 can change the position of the adjustment nut 35 on the adjustment stud 34, thereby changing the distance between the adjustment nut 35 and the top surface of the bottom of the C-shaped fastener 36.

[0047] When the adjustment nut 35 moves downward, it can drive the C-shaped fastener 36 to move downward, thereby changing the pressure between the bottom surface of the top of the C-shaped fastener 36 and the edge seal 12.

[0048] The bottom fastener 4 includes a second U-shaped plate 41, which is slidably connected to the cross beam 23 through a second fastener. A fastener connecting plate 44 is provided at the top of the second U-shaped plate 41 close to the photovoltaic panel 1. A Z-shaped fastener 45 is connected above the fastener connecting plate 44 through a second adjustment component. The bottom surface of the head of the Z-shaped fastener 45 abuts against the inner bottom surface of the tail of the edge seal 12.

[0049] The second adjustment component is used to control the distance between the bottom surface of the head of the Z-shaped fastener 45 and the edge seal 12. When the bottom surface of the head of the Z-shaped fastener 45 abuts against the inner bottom surface of the tail of the edge seal 12, it can cooperate with the cross beam 23 to clamp the edge seal 12, and use friction to fix the edge seal 12 to prevent the edge seal 12 from sliding downward, thereby preventing the photovoltaic panel 1 from moving.

[0050] The second fastener includes a second bolt 43. The screw rod of the second bolt 43 penetrates through the second U-shaped plate 41 and is threadedly connected to a second slider 42 through an opening on the side surface of the cross beam 23. The second slider 42 can slide in the installation groove 24.

[0051] Since the second bolt 43 is threadedly connected to the second slider 42, rotating the second bolt 43 can drive the second slider 42 to move along the axis direction of the second bolt 43, thereby controlling the distance between the second slider 42 and the inner wall of the cross beam 23.

[0052] When the second slider 42 abuts against the inner wall of the cross beam 23, it cooperates with the second U-shaped plate 41 to clamp the cross beam 23 to realize the fixation of the second U-shaped plate 41.

[0053] When the second slider 42 separates from the inner side wall of the cross beam 23, the second U-shaped plate 41 can slide along the cross beam 23.

[0054] The second adjusting component includes a second stud 46. The second stud 46 is vertically welded and installed at the center of the bottom surface of the tail of the Z-shaped fastener 45. The second stud 46 penetrates downward through the fastener connecting plate 44 and is threadedly connected with a locking nut 48. A first spring 47 is sleeved on the second stud 46 above the fastener connecting plate 44.

[0055] Since the locking nut 48 is threadedly connected with the second stud 46, rotating the locking nut 48 can change the position of the locking nut 48 on the second stud 46.

[0056] When the locking nut 48 moves upward, the top surface of the locking nut 48 abuts against the fastener connecting plate 44, and it will drive the Z-shaped fastener 45 to move downward through the second stud 46, thereby changing the distance between the bottom surface of the head of the Z-shaped fastener 45 and the inner bottom surface of the tail of the edge seal 12, and simultaneously compressing the first spring 47.

[0057] When the locking nut 48 moves downward, the distance between the top surface of the locking nut 48 and the bottom surface of the fastener connecting plate 44 increases, the pressure on the first spring 47 decreases, and under the elastic force of the first spring 47, the Z-shaped fastener 45 and the second stud 46 move upward, so that the bottom surface of the head of the Z-shaped fastener 45 separates from the inner bottom surface of the tail of the edge seal 12.

[0058] Until the bottom surface of the tail of the Z-shaped fastener 45 is higher than the inner bottom surface of the tail of the edge seal 12, at this time, the Z-shaped fastener 45 can be rotated so that the head of the Z-shaped fastener 45 leaves the tail of the edge seal 12.

[0059] In this embodiment, when the operator uses this device, loosen the first bolt 33 and the second bolt 43 so that the first U-shaped plate 31 and the second U-shaped plate 41 can slide along the cross beam 23.

[0060] Rotate the adjusting nut 35 so that the distance from the bottom surface of the head of the C-shaped fastener 36 to the top surface of the cross beam 23 is greater than the inner thickness of the edge seal 12.

[0061] At the same time, rotate the locking nut 48 so that the bottom surface of the tail of the Z-shaped fastener 45 is higher than the inner thickness of the edge seal 12, and then rotate the Z-shaped fastener 45 so that the Z-shaped fastener 45 is parallel to the cross beam 23.

[0062] Place the photovoltaic panel 1 on the cross beam 23 so that the head of the C-shaped fastener 36 is inserted into the inner side of the top of the edge seal 12. Rotate the adjusting nut 35 so that the bottom surface of the head of the C-shaped fastener 36 abuts against the inner bottom surface of the head of the edge seal 12.

[0063] Rotate the Z-shaped fastener 45 again to insert the head of the Z-shaped fastener 45 into the inner side of the tail of the edge seal 12, and then rotate the lock nut 48 so that the bottom surface of the head of the Z-shaped fastener 45 abuts against the top surface of the inner side of the tail of the edge seal 12. The preliminary fixation of the photovoltaic panel 1 is completed.

[0064] At this time, applying a horizontal force to the photovoltaic panel 1 can drive the photovoltaic panel 1 to slide along the cross beam 23, thereby controlling the distance between two adjacent photovoltaic panels 1.

[0065] After the distance adjustment is completed, tighten the first bolt 33 and the second bolt 43 to complete the fixation of the first U-shaped plate 31 and the second U-shaped plate 41. Then tighten the adjusting nut 35 to fix the head of the edge seal 12 by using the C-shaped fastener 36, and tighten the lock nut 48 to fix the tail of the edge seal 12 by using the Z-shaped fastener 45.

[0066] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
