Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a photovoltaic support structure and a photovoltaic system. Background Technology

[0002] The installation and protection of photovoltaic (PV) panels has always been a key area of ​​technological research and development. Conventional PV brackets only fix the PV panels and cannot assist in the arrangement of power lines, resulting in a messy and disorganized power line layout in the PV system. This can lead to tangled and squeezed lines, increasing the risk of circuit failures and making PV system maintenance more difficult. At the same time, after fixing the PV panels with brackets, the bottom of the PV panels is exposed to the natural environment for a long time. External factors such as wind, snow, rain, and flying sand can easily come into direct contact with the bottom of the PV panels, increasing the risk of damage to the bottom of the PV panels, affecting their service life, and impacting the long-term stability of the PV panels. Utility Model Content

[0003] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a photovoltaic support structure and photovoltaic system that facilitates the orderly arrangement of power lines and facilitates real-time shading of the bottom of the photovoltaic panel, reducing the contact of wind, snow, rain and flying sand with the bottom of the photovoltaic panel, and reducing the risk of damage to the photovoltaic panel.

[0004] To achieve the above objectives, the following structure is proposed:

A traction opening is provided on the side of the first long box and the two second long boxes facing each other. The interior of the second long box contains two No. 1 winding components and one No. 2 winding component. The surface of the No. 1 winding component is covered with a waterproof cloth, and the surface of the No. 2 winding component is covered with a wear-resistant rope. One end of the wear-resistant rope is fixedly connected to one end of the waterproof cloth through a traction opening. Side plates are fixedly connected to the lower surfaces of the front and rear walls of the mounting frame. Both the No. 2 and No. 1 long boxes have lead screws at their bottoms, with mounting plates rotatably connected to their upper ends. The lower ends of the No. 1 and No. 2 winding components are fixedly connected to the upper surface of the mounting plate. This reduces the contact area between external factors and the bottom of the photovoltaic panel, lowering the risk of damage to the bottom of the photovoltaic panel.

[0006] According to the photovoltaic support structure and photovoltaic system described in this utility model, the front surfaces of both the first and second long boxes are provided with passage openings, through which the front ends of the first and second winding components pass into the interior of the first and second long boxes. This improves the convenience of assembling and disassembling the winding components.

[0007] According to the photovoltaic support structure and photovoltaic system described in this utility model, both the first winding component and the second winding component consist of two vertical plates and a long rod. The two vertical plates are distributed opposite each other, and the vertical plates are fixedly connected to the mounting plate. This improves the convenience of inspecting and maintaining the winding components.

[0008] According to the photovoltaic support structure and photovoltaic system described in this utility model, the long rod is rotatably connected to the vertical plate, and the front end of the long rod passes through the vertical plate located in front. This improves the convenience of using the winding component.

[0009] According to the photovoltaic support structure and photovoltaic system described in this utility model, the height of the traction opening on the surface of the second long box is greater than the thickness of the waterproof cloth and the same as the diameter of the wear-resistant rope, while the height of the traction opening on the surface of the first long box is the same as the thickness of the waterproof cloth. This improves the smoothness of movement of the waterproof cloth and the wear-resistant rope.

[0010] According to the photovoltaic support structure and photovoltaic system described in this utility model, a motor is fixedly connected to the upper surface of the mounting plate, and the output end of the motor is fixedly connected to the front end of the long rod. This improves the convenience of winding waterproof cloth and wear-resistant rope.

[0022] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0023] Reference Figure 1-4 As a first embodiment: This utility model embodiment provides a photovoltaic support structure and photovoltaic system, which includes: a mounting frame 2, a support rod 1 fixedly connected to the lower surface of the mounting frame 2, a horizontal plate 3 fixedly connected to the surface of the mounting frame 2, the support rod 1 and the horizontal plate 3 are used to provide support for the photovoltaic panel 19, and the lower ends of the mounting frame 2 and the horizontal plate 3 are provided with lead wire holes 6, the lead wire holes 6 are used to limit the range of motion of the power lines at the bottom of the photovoltaic panel 19, and a sealing plug 7 is provided inside the lead wire holes 6 on the surface of the mounting frame 2, the sealing plug 7 is used to seal unused lead wire holes 6.

[0024] Specifically, the photovoltaic panel 19 is directly fixed to the upper surface of the mounting frame 2 and the horizontal plate 3. When pulling the power cord, the power cord is first passed through the lead hole 6 on the surface of the horizontal plate 3. Then, the lead hole 6 on the left or right side is released according to the wiring requirements to ensure that the power cord is always above the waterproof cloth 10 after being arranged.

[0025] The lower surfaces of the left and right walls of the mounting frame 2 and the lower surface of the horizontal plate 3 are respectively fixedly connected to a second long box 15 and a first long box 4. Each of the two facing sides of the first long box 4 and the two second long boxes 15 has a traction opening 5. The second long boxes 15 and the first long box 4 are used to reduce the contact area between external factors and the waterproof cloth 10. The height of the traction opening 5 on the surface of the second long box 15 is greater than the thickness of the waterproof cloth 10 and the same as the diameter of the abrasion-resistant rope 9. The height of the traction opening 5 on the surface of the first long box 4 is the same as the thickness of the waterproof cloth 10. Inside the first long box 4 and the second long box 15, there are two first winding parts 16 and one second winding part 16. Winding component 8, winding component 16, and winding component 2 each consist of two vertical plates 18 and a long rod 17. The two vertical plates 18 are distributed opposite each other and are fixedly connected to the mounting plate 12. The long rod 17 is rotatably connected to the vertical plates 18, and the front end of the long rod 17 passes through the vertical plate 18 located in front. The surface of winding component 16 is provided with a waterproof cloth 10, and the surface of winding component 2 is provided with a wear-resistant rope 9. One end of the wear-resistant rope 9 passes through the traction opening 5 and is fixedly connected to one end of the waterproof cloth 10. The winding component, the wear-resistant rope 9, and the waterproof cloth 10 cooperate to provide conditions for the bracket to shield the bottom of the photovoltaic panel 19.

[0026] Specifically, under normal conditions, the waterproof cloth 10 is in a wound state, while the abrasion-resistant rope 9 is pulled out and the second long box 15 is in a state of tension. When the external environment is poor, the second winding component 8 is rotated to wind up the pulled-out abrasion-resistant rope 9. During the winding process, the long rod 17 of the first winding component 16 is automatically rotated under the influence of tension, causing the waterproof cloth 10 on its surface to be unfolded. At the same time, since the height of the traction opening 5 on the surface of the second long box 15 is greater than the thickness of the waterproof cloth 10, when the waterproof cloth 10 is close to the second long box 15, under the influence of the tension transmitted by the abrasion-resistant rope 9, the end of the waterproof cloth 10 that is pulled out can be wound on the surface of the second winding component 8, thereby keeping the stretched waterproof cloth 10 in a taut state.

[0027] Side plates 11 are fixedly connected to the lower surfaces of the front and rear walls of the mounting frame 2. The side plates 11 cooperate with the stretched waterproof cloth 10 to improve the sealing effect of the bottom of the photovoltaic panel 19. Screw rods 13 are installed below both the second long box 15 and the first long box 4. The upper end of the screw rod 13 is rotatably connected to the mounting plate 12. The screw rod 13 cooperates with the mounting plate 12 to facilitate adjustment of the height of the winding components. The lower ends of the first winding component 16 and the second winding component 8 are fixedly connected to the upper surface of the mounting plate 12. The mounting plate 1... A motor 20 is fixedly connected to the upper surface of 2. The output end of the motor 20 is fixedly connected to the front end of the long rod 17. The motor 20 is used to improve the convenience of rotating the winding part. The front surfaces of the first long box 4 and the second long box 15 are provided with passage openings 14. The front ends of the first winding part 16 and the second winding part 8 pass through the passage openings 14 and enter the interior of the first long box 4 and the second long box 15. The passage openings 14 are used to provide the first winding part 16 and the second winding part 8 with the conditions to freely enter and exit the long box.

[0028] Specifically, manually rotating the upper end of the lead screw 13 extends the lead screw 13, thereby pushing the mounting plate 12 closer to the long box. Since the mounting plate 12 rotates relative to the lead screw 13, it is not affected by rotational stress. When the mounting plate 12 is in close contact with the lower surface of the long box, the winding part is completely inserted into the interior of the long box. Conversely, when rotating the lead screw 13 to retract, the mounting plate 12 drives the winding part away from the long box. During the process of the winding part moving away from the long box, the wear-resistant rope 9 is blocked by the inner wall of the traction opening 5, so the wound part of the wear-resistant rope 9 is pulled and released.

[0029] Reference Figure 5 As a second embodiment: a photovoltaic system of this embodiment includes: a photovoltaic panel 19, and a photovoltaic support structure as described in embodiment one is disposed below the photovoltaic panel 19.

[0030] Working principle: The photovoltaic panel 19 is directly fixed to the upper surface of the mounting frame 2 and the horizontal plate 3 using bolts and nuts. Due to the influence of the lead hole 6, the power line at the bottom of the photovoltaic panel 19 is always at the top of the waterproof cloth 10. It will not be blocked by the power line during the unfolding and rewinding of the waterproof cloth 10. When the waterproof cloth 10 needs to be inspected, the height of the screw 13 is lowered by rotating it, thereby lowering the height of the mounting plate 12, so as to take out the winding part and provide the workers with the conditions to inspect the winding part.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
