[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-3 A photovoltaic module wind pressure plate structure includes a plurality of parallel horizontal frames 1, the horizontal frame 1 is provided with a plurality of positioning plates 2, the positioning plates 2 are U-shaped, the top ends of the positioning plates 2 are symmetrically provided with lower pressure plates 3, the inner ends of the positioning plates 2 are fixedly connected with positioning rods 4, and the upper outer part of the positioning rods 4 is provided with threads, the top ends of the two positioning rods 4 are penetrated by a top plate 5, the two ends of the top plates 5 are fixedly connected with upper pressure plates 6, and the two upper pressure plates 6 are symmetrically arranged, a photovoltaic panel 7 is clamped between the upper pressure plate 6 and the lower pressure plate 3 at the same end, and a locking nut 8 is connected with a threaded sleeve on the upper outer side of the positioning rod 4;

[0021] In the technical solution adopted above, the positioning rod 4 is in a state of being movable and penetrating the top plate 5. By placing the photovoltaic panel 7 between the upper pressure plate 6 and the lower pressure plate 3, and then tightening the locking nut 8 downward, the locking nut 8 drives the upper pressure plate 6 downward and firmly presses against the surface of the photovoltaic panel 7, thereby achieving the purpose of fixing the photovoltaic panel 7. This device can simultaneously press and fix the edges of the photovoltaic panels 7 at both ends.

[0022] A baffle 9 is fixedly connected to the bottom of the upper pressing plate 6, and protective lines are provided on the contact surfaces between the upper pressing plate 6 and the lower pressing plate 3 and the photovoltaic panel 7;

[0023] In the technical solution adopted above, the baffle plate 9 is arranged to position the edge of the photovoltaic panel 7 so as to extend into the position between the upper pressure plate 6 and the lower pressure plate 3, so that when the edge of the photovoltaic panel 7 is against the position of the baffle plate 9, the photovoltaic panel 7 can be pressed and fixed. The anti-slip grooves on the upper pressure plate 6 and the lower pressure plate 3 are arranged to increase the friction force in contact with the surface of the photovoltaic panel 7 and improve the fixing effect.

[0024] An arc-shaped hook plate 10 is extended toward the inner side of the positioning plate 2 at one end of the lower pressing plate 3 close to the positioning plate 2. The arc-shaped hook plates 10 on the two lower pressing plates 3 are symmetrically arranged, and a movable plate 11 is installed between the two arc-shaped hook plates 10. The positioning rod 4 movably penetrates the movable plate 11, and a compression spring 12 is sleeved on the portion of the positioning rod 4 located between the top of the movable plate 11 and the bottom of the top plate 5.

[0025] The technical solution adopted above, as shown in the accompanying drawings, the bottom of the two ends of the movable plate 11 are hooked with the bent parts of the two arc-shaped hook plates 10 to achieve the effect of connection. In the process of the locking nut 8 driving the top plate 5 to move downward, the bottom of the top plate 5 will squeeze the compression spring 12, and the compression spring 12 will deform and shrink. The reaction force of the compression spring 12 will push the movable plate 11 to move downward, so that the movable plate 11 squeezes the two arc-shaped hook plates 10 downward. The arc-shaped hook plate 10 and the lower pressure plate 3 are an integral structure with a certain deformation ability, and the middle part of the overall structure is connected to the positioning plate 2. When the arc-shaped hook plate 10 moves downward slightly, the lower pressure plate 3 will be slightly tilted up, thereby cooperating with the upper pressure plate 6 to clamp the photovoltaic panel 7 more firmly, thereby improving the grip of the photovoltaic panel 7 and preventing it from sliding easily due to strong winds.

[0026] The cross frame 1 is a hollow structure, and a guide groove 13 is provided on the top of the cross frame 1. L-shaped plates 14 are fixedly connected to both sides of the bottom end of the positioning plate 2, and the two L-shaped plates 14 are symmetrically arranged. A triangular plate 15 is connected to the bottom end of the L-shaped plate 14, and the bottom ends of the two triangular plates 15 are commonly connected to a bottom plate 16. The overall structure composed of the two L-shaped plates 14, the two triangular plates 15 and the bottom plate 16 is slidably connected to the inner side of the cross frame 1 through the guide groove 13;

[0027] In the technical solution adopted above, the inner cavity of the cross frame 1 and the guide groove 13 form a T-shaped groove structure, and the external structure composed of two L-shaped plates 14, two triangular plates 15 and the bottom plate 16 is similar to a T-shape, which matches the T-shaped groove structure on the cross frame 1 and can slide freely inside to adjust the position of the positioning plate 2.

[0028] An adjusting screw 17 is installed through a thread in the middle of the positioning plate 2, and the diameter of the adjusting screw 17 is larger than the distance between the two triangular plates 15, and a conical column is fixed to the bottom end of the adjusting screw 17;

[0029] In the technical solution adopted above, the two triangular plates 15 are in a horizontal state, and the two corners are adjacent to each other with a small gap. When the adjusting screw 17 is turned downward, the triangular plate 15 will be squeezed and deformed outward, so that the structure composed of the L-shaped plate 14, the triangular plate 15 and the bottom plate 16 tends to deform outward, so that the outer wall will gradually cling to the inner wall of the horizontal frame 1, the friction increases, and it cannot slide, thereby achieving the position of the fixed positioning plate 2.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
