Description

Technical Field

[0001] The utility model belongs to the field of solar photovoltaic panel installation, in particular to a fastening structure of a solar photovoltaic panel. Background Art

[0002] Solar photovoltaic panels are devices that use the photovoltaic effect to directly convert solar radiation into electrical energy. They are mainly composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, AC distribution cabinets, solar tracking control systems and other equipment. Among them, solar cells are the core components of photovoltaic power generation systems, which can convert light energy into electrical energy. Solar photovoltaic panels can be used in various fields, such as independent photovoltaic power generation systems, grid-connected photovoltaic power generation systems, distributed photovoltaic power generation systems, etc. When installing solar photovoltaic panels, a large number of bolts are usually used for tightening, which is time-consuming and labor-intensive.

By lowering the support rod, the clips are propped open, rotated at an angle, and the photovoltaic panel is clamped in cooperation with the U-shaped clamp. The fastening structure of the solar photovoltaic module has the following disadvantages:

[0004] Since the support rod is located at the uppermost end of the gap between the clips and is in close contact with the clips, when the support rod moves to the lowermost end, the clips are stretched to a nearly vertical state at their maximum, and the clip angle has a small range of variation. A fastening structure of one specification can only adapt to photovoltaic panels of corresponding specifications, and has poor adaptability. Utility Model Content

[0018] Figure 1 It is a schematic diagram of the structure of the utility model;

[0019] Figure 2 It is the front view of the utility model.

[0020] In the figure, there are U-shaped clamp 1, moving rod 2, external connecting plate 3, rotating head 4, positioning rod 5, limiting nut 6, transition plate 7, support plate 8, and clamping piece 9. DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and embodiments:

[0022] In the present invention, the terms "longitudinal", "lateral", "vertical", "upper", "lower", "top", "bottom" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or position relationship shown is only for the convenience of describing the present invention, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] The fastening structure is the same as that of a traditional solar photovoltaic panel, including a U-shaped clip 1, which is used to wrap the solar panel. The top of the U-shaped clip 1 is provided with two symmetrical clips 9, and the top of the clip 9 is rotatably connected to the U-shaped clip 1, and a gap is left between the two clips 9. A middle hole is provided at the center of the top of the U-shaped clip 1, and a positioning rod 5 is movably inserted in the middle hole. A transition plate 7 is provided in the gap between the two clips 9, and the bottom end of the positioning rod 5 is connected to the transition plate 7.

[0024] Different from the fastening structure of traditional solar photovoltaic panels, such as Figure 1 and Figure 2As shown, the fastening structure of the solar photovoltaic panel disclosed by the utility model has the same width of the gap between the two clips 9 in the vertical direction; in the horizontal direction, gaps are set between the two ends of the transition plate 7 and the corresponding clips 9, and a support plate 8 is set in the gap between the transition plate 7 and the corresponding clips 9. The support plate 8 is tilted in the gap, and one end of the support plate 8 is hinged to the transition plate 7, and the other end is hinged to the clip 9. Figure 1 As shown, the positioning rod 5 is at the highest position, that is, the transition plate 7 is at the highest position, and the support plate 8 gradually extends downward from the end connected to the transition plate 7 to the end connected to the clip 9. In this way, when the positioning rod 5 pushes the transition plate 7 downward, the support plate 8 rotates, and the angle of the support plate 8 increases, thereby spreading the two clips 9 apart, so that the two clips 9 are distributed in an eight-shaped shape.

[0025] The middle hole is a threaded hole, the positioning rod 5 is a threaded rod, and the positioning rod 5 is threadedly connected to the middle hole, so that the positioning rod 5 is easy to move.

[0026] Two round through holes are provided in the middle of the top of the U-shaped clamp 1 along the longitudinal direction, and the two round through holes are located on both sides of the middle hole. A moving rod 2 is movably inserted in the round through hole, and the round through hole is a bare hole without threads, which is used to limit the horizontal displacement of the moving rod 2 so that it can only move axially. The top ends of the two moving rods 2 are connected to an external connecting plate 3, the top end of the positioning rod 5 passes through the external connecting plate 3 and is movably connected to the external connecting plate 3, and the bottom end of the moving rod 2 is connected to the transition plate 7; and the bottom end of the positioning rod 5 is rotatably connected to the transition plate 7.

[0027] In order to facilitate assembly and disassembly and ensure that the moving rod 2 can rotate, preferably, through holes are provided on the transition plate 7 at positions corresponding to the moving rod 2 and the positioning rod 5; the moving rod 2 and the positioning rod 5 are inserted into the corresponding through holes, and limiting structures are provided between the moving rod 2 and the transition plate 7 and between the positioning rod 5 and the transition plate 7, respectively.

[0028] The limiting structure serves to prevent the movable rod 2 from being disengaged from the transition plate 7, and the positioning rod 5 from being disengaged from the transition plate 7, thereby ensuring normal use. The limiting structure includes at least two limiting nuts 6 that cooperate with the bottom threads of the movable rod 2, and the two limiting nuts 6 are located on the upper and lower sides of the transition plate 7.

[0029] In order to facilitate the application of a force to drive the positioning rod 5 to rotate, thereby realizing the axial movement of the positioning rod 5 and further driving the transition plate 7 to move, the top end of the positioning rod 5 is arranged on the rotating head 4. The rotating head 4 can adopt a rhombus-cube structure and can be used in combination with an external driving device such as a wrench to realize the rotation of the screw positioning rod 5.

[0030] Preferably, the two sides of the bottom of the clip 9 are respectively provided with convex parts protruding in the transverse direction. When the internal connecting plate 7 moves up and down, the support plate 8 is driven to rotate, thereby realizing the rotation of the clip 9. The clip 9 is connected with the support plate 8 and the U-shaped clip 1, and can realize relative free rotation under the hinge structure. The convex part at the end of the clip 9 increases the fastening and prevents it from falling off after fastening.

[0031] The fastening structure of the solar photovoltaic panel disclosed by the utility model can drive all parts by axial movement of only one positioning rod 5 to realize the rotation of the clamping piece 9, thereby clamping the solar panel. No more operating tools are required, and no more screws are required for fastening. The operation is convenient and efficient.

[0032] The positioning rod 5 moves continuously in the axial direction, which can realize stepless adjustment, and the clamping piece is in an 8-shaped shape, which can realize the adjustment of the clamping piece 9 at any angle, and can meet the connection of components of different models, with wide applicability. At the same time, it can be stably tightened at any angle with high precision.

[0033] All components of the fastening structure of the solar photovoltaic panel disclosed by the utility model can be made of high-strength steel, and the material has good durability. Compared with traditional screws, it has less wear and tear, is not easy to loosen after connection, and has good fastening effect.

[0034] After installation, it can be recycled again. At the same time, the parts have less wear and tear and can be recycled more often, which is beneficial to saving resources and has good environmental protection effects.
