Description

Technical Field

[0001] This utility model is a side-pressing device for photovoltaic modules, belonging to the field of photovoltaic construction. Background Technology

[0002] Edge clamps are crucial components for ensuring the stability and safety of photovoltaic (PV) systems. Proper selection and installation of edge clamps not only improves the wind resistance and lifespan of the PV system but also reduces maintenance costs and risks. Edge clamps should be evenly distributed along the edges of the PV modules to ensure uniform stress. Commonly used edge clamps include U-shaped and Z-shaped types. U-shaped clamps are placed between adjacent PV panels, while Z-shaped clamps are used at the edges. Therefore, at least two types of edge clamps are required during PV module installation, which is inconvenient for management. Thus, a universal edge clamping device for PV modules needs to be designed. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a side pressing device for photovoltaic modules to solve the problems mentioned in the background technology. This utility model is universal and does not require the production of at least two types of side pressing parts.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a photovoltaic module edge pressing device, comprising a connecting plate, with vertical portions on both sides of the connecting plate, an insertion groove on the side of the connecting plate facing the vertical portions, an insertion strip installed on the side of the vertical portions facing the connecting plate, the insertion strip being inserted into the insertion groove, a pressing portion for pressing against the edge of the photovoltaic panel being installed at the end of the vertical portions away from the insertion strip, a through hole being provided at the center of the upper surface of the connecting plate, an internal hexagon screw being inserted into the through hole, a square nut being threaded to the lower end of the internal hexagon screw, a U-shaped frame being wrapped around the square nut, the internal hexagon screw passing through the U-shaped frame, and clips for locking into aluminum profile guide rails being installed at both ends of the U-shaped frame, an arc-shaped groove concentrically arranged with the through hole being provided at the center of the insertion strip, the internal hexagon screw passing through the arc-shaped groove.

[0005] Furthermore, two symmetrically arranged rectangular openings are provided on the upper part of one side of the vertical part, and two rectangular rods are symmetrically installed on the side of the pressing part facing the vertical part. The rectangular rods pass through the rectangular openings, and two positioning screws for restricting the rectangular rods within the rectangular openings are threaded to the upper surface of the vertical part.

[0006] Furthermore, two vertical holes are symmetrically formed on the upper surface of the vertical part, and the vertical holes communicate with the rectangular opening. An internally threaded sleeve is provided on the upper side of the vertical hole, which is concentrically arranged with the vertical hole. One end of the internally threaded sleeve is connected and fixed to the vertical part. The positioning screw is threadedly connected to the internally threaded sleeve, and the lower end of the positioning screw passes through the vertical hole and contacts the rectangular rod.

[0007] Furthermore, the cross-section of the connector strip is "T" shaped, and the cross-section of the connector groove is "T" shaped.

[0008] Furthermore, ribs for supporting the square nut are installed on both parallel sides of the U-shaped frame, and the ribs and the U-shaped frame are integrally formed.

[0009] Furthermore, the card head and the U-shaped frame are integrally formed, and a circular opening is provided on the upper surface of the U-shaped frame, through which the internal hexagonal screw passes.

[0010] The beneficial effects of this utility model are:

[0011] 1. Insert the connector strip into both slots to complete the assembly of the two vertical parts and the connecting plate. At this time, the pressing part, the vertical part and the connecting plate together form a U-shaped edge pressing part. Insert the connector strip into one slot to form a Z-shaped edge pressing part, which achieves universality and eliminates the need to produce at least two types of edge pressing parts.

[0012] 2. After inserting the connector strip into the connector slot, arrange the arc-shaped slot and the through hole concentrically. Then, after the hex socket screw passes through the through hole, the arc-shaped slot and the hex socket screw cooperate with each other to prevent the connector strip from moving randomly along the connector slot, so that the relative position of the vertical part and the connecting plate remains unchanged, thereby improving the stability of the structure.

[0013] 3. Adjust the position of the rectangular rod along the rectangular opening. At this time, the distance between the pressing part and the vertical part changes. When the relative position of the pressing part and the photovoltaic panel meets the requirements, use the positioning screws to limit the relative position of the rectangular rod and the vertical part, so as to adjust the relative position of the pressing part and the photovoltaic panel as needed.

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-3 This utility model provides a technical solution: a photovoltaic module edge pressing device, including a connecting plate 1, with vertical parts 3 on both sides of the connecting plate 1. The side of the connecting plate 1 facing the vertical parts 3 has a T-shaped insertion groove 14. The side of the vertical parts 3 facing the connecting plate 1 is equipped with a T-shaped insertion strip 2. The end of the vertical parts 3 away from the insertion strip 2 is equipped with a pressing part 4 for pressing against the edge of the photovoltaic panel. Insertion strips 2 are inserted into both insertion grooves 14, thereby completing the assembly of the two vertical parts 3 with the connecting plate 1. At this time, the pressing part 4, the vertical parts 3 and the connecting plate 1 together form a U-shaped edge pressing component. Insertion strips 2 are inserted into one insertion groove 14, thereby forming a Z-shaped edge pressing component with one vertical part 3, one pressing part 4 and the connecting plate 1 together, achieving universality and eliminating the need to produce at least two types of edge pressing components.

[0021] See Figures 1-3 A through hole 13 is provided in the middle of the upper surface of the connecting plate 1. A hexagonal socket screw 7 is inserted into the through hole 13. A square nut 10 is threaded to the lower end of the hexagonal socket screw 7. A U-shaped frame 9 is wrapped around the square nut 10. Ribs 11 for supporting the square nut 10 are installed on two parallel sides inside the U-shaped frame 9. The ribs 11 and the U-shaped frame 9 are integrally formed. The hexagonal socket screw 7 passes through the round opening on the upper surface of the U-shaped frame 9. Both ends of the U-shaped frame 9 are equipped with clips 12 for locking into the aluminum profile guide rail. The head 12 and the U-shaped frame 9 are integrally formed. The middle of the plug strip 2 is provided with an arc-shaped groove 16 arranged concentrically with the through hole 13. The internal hex screw 7 passes through the arc-shaped groove 16. After the plug strip 2 is inserted into the plug groove 14, the arc-shaped groove 16 is arranged concentrically with the through hole 13. Then, after the internal hex screw 7 passes through the through hole 13, the arc-shaped groove 16 and the internal hex screw 7 cooperate with each other to prevent the plug strip 2 from moving randomly along the plug groove 14, so that the relative position of the vertical part 3 and the connecting plate 1 remains unchanged, thereby improving the stability of the structure.

[0022] See Figures 1-3 Two symmetrically arranged rectangular openings 15 are provided on the upper part of one side of the vertical part 3. Two rectangular rods 6 are symmetrically installed on the side of the holding part 4 facing the vertical part 3. The rectangular rods 6 pass through the rectangular openings 15. Two positioning screws 5 are threadedly connected to the upper surface of the vertical part 3 to restrict the rectangular rods 6 within the rectangular openings 15. Two vertical holes are symmetrically provided on the upper surface of the vertical part 3, which communicate with the rectangular openings 15. An internally threaded sleeve 8 is provided on the upper side of the vertical hole, which is concentrically arranged with the vertical hole. One end of the internally threaded sleeve 8 is connected and fixed to the vertical part 3. The positioning screws 5 are threadedly connected to the internally threaded sleeve 8. The lower end of the positioning screws 5 passes through the vertical hole and contacts the rectangular rods 6. The design of the internally threaded sleeve 8 improves the connection stability between the positioning screws 5 and the vertical part 3. The position of the rectangular rods 6 is adjusted along the rectangular openings 15. At this time, the distance between the holding part 4 and the vertical part 3 changes. When the relative position of the holding part 4 and the photovoltaic panel meets the requirements, the positioning screws 5 are used to restrict the relative position of the rectangular rods 6 and the vertical part 3, so as to adjust the relative position of the holding part 4 and the photovoltaic panel as needed.
