[0024] In order to clearly and completely describe the purpose, technical solution of the present utility model and make the advantages more clear, the following further details the embodiments of the present utility model with reference to the drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present utility model, rather than all of the embodiments, and are only used to explain the embodiments of the present utility model, not to limit the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0025] Embodiment 1, please refer to Figures 1-7 , the present utility model provides a technical solution: a splicable modular photovoltaic module, including: a photovoltaic panel 1.

[0026] Specifically, a protection frame 2 is fixedly covered at the edge of the photovoltaic panel 1. The protection frame 2 is made of a hard material and is mainly used to protect the photovoltaic panel 1, avoiding damage to the edge of the photovoltaic panel 1 due to bumps. A support cross beam 3 for supporting it is provided below the protection frame 2. As Figure 1 shown, two support cross beams 3 are provided and are parallel to each other, which is used to ensure the stability of the support for the protection frame 2. The cross-section of the support cross beam 3 is set in a "匚" shape with an upward opening. A pressing plate 4 is provided above the support cross beam 3. Two vertical plates 41 are fixed on the lower surface of the pressing plate 4, and the two vertical plates 41 are respectively located on both sides of the support cross beam 3. As Figure 2 shown, the two vertical plates 41 are placed on both sides of the support cross beam 3 from top to bottom. At this time, the support cross beam 3 can limit the position of the pressing plate 4, avoiding the position deviation of the pressing plate 4 in the horizontal direction perpendicular to the support cross beam 3. The pressing plate 4 can only move up and down and along the length direction of the support cross beam 3;

[0027] Secondly, the vertical plate 41 is located between two adjacent protective frames 2, and the pressing plate 4 presses the two adjacent protective frames 2 simultaneously from top to bottom. The vertical plate 41 itself is a flat structure, and only a small gap needs to be left between two adjacent protective frames 2 for the vertical plate 41 to pass through, so as to ensure that the two adjacent photovoltaic panels 1 are in a compact state when the device is installed, saving space occupancy. A limiting baffle 42 is fixed at the lower end of the vertical plate 41, and a positioning plug-in 5 is movably inserted into the side surface of the support crossbeam 3. The positioning plug-in 5 buckles on the outside of the vertical plate 41, and the lower side of the positioning plug-in 5 presses on the upper surface of the limiting baffle 42. The setting of the positioning plug-in 5 can be used to further limit the pressing plate 4, so that the pressing plate 4 always maintains a state of pressing down on the protective frame 2. At the same time, the positioning plug-in 5 cannot shift in the length direction of the support crossbeam 3, thus preventing the pressing plate 4 from moving along the length direction of the support crossbeam 3 and causing it to错开 from the protective frame 2. The device supports the protective frame 2 through the support crossbeam 3, presses and positions the protective frame 2 through the pressing plate 4, and limits the pressing plate 4 through the positioning plug-in 5 to prevent the pressing plate 4 from错开 from the protective frame 2, thereby ensuring the stable position of the protective frame 2 and not being easily loosened.

[0028] In order to connect the positioning plug-in 5 with the support crossbeam 3, the present application also has insertion slots 31 penetrating through both side surfaces of the support crossbeam 3. The positioning plug-in 5 is arranged in a horizontally placed "C" shape. The end of the positioning plug-in 5 sequentially passes through the insertion slots 31 on both sides of the support crossbeam 3 movably. After the "C" shaped positioning plug-in 5 buckles on the outside of the vertical plate 41, it can position the vertical plate 41 from both sides, preventing the vertical plate 41 from shifting in position. Since insertion slots 31 are provided on both sides of the support crossbeam 3, after the positioning plug-in 5 is inserted and matched with the insertion slots 31, firstly, the positioning plug-in 5 itself can remain stable and will not tilt downwards; secondly, the downward pressing of the positioning plug-in 5 on the limiting baffle 42 can ensure that the pressing plate 4 always has a tendency to move downwards, thereby realizing the stable downward pressing of the protective frame 2.

[0029] In order to adjust the position of the positioning plug-in 5 on the support crossbeam 3, multiple groups of insertion slots 3 are provided in the present application and are evenly distributed in the length direction of the support crossbeam 3. The setting of multiple groups of insertion slots 31 can be used to install multiple pressing plates 4 at multiple different positions on the support crossbeam 3, thereby realizing the installation and positioning of any two adjacent protective frames 2. Each group of insertion slots 31 has multiple ones, and the distance between two adjacent insertion slots 31 is equal to the distance between the two ends of the positioning plug-in 5. By inserting the positioning plug-in 5 into other insertion slots 31 in the same group, the position of the positioning plug-in 5 can be adjusted along the length direction of the support crossbeam 3, thereby adapting to different sizes of photovoltaic panels 1 and protective frames 2, ensuring that the vertical plate 41 can closely adhere to the side surface of the protective frame 2, and minimizing the gap between two adjacent protective frames 2 as much as possible.

[0030] To prevent the protective frame 2 from sliding along the direction of the vertical support beam 3, this application also includes a support protrusion 21 fixedly installed at the bottom of the protective frame 2, and the support protrusion 21 is movably inserted into the inner cavity of the support beam 3 from top to bottom. The support protrusion 21 is used to support the protective frame 2 when it is placed on the ground, and when the protective frame 2 is placed on the support beam 3, the support protrusion 21 can limit the protective frame 2 to prevent it from sliding along the direction of the vertical support beam 3. Both sides of the support beam 3 are folded outward to form support flanges 32, which abut against the lower surface of the protective frame 2 from bottom to top. The support flanges 32 can increase the contact area between the support beam 3 and the protective frame 2, thereby improving the stability of the support beam 3 in supporting the protective frame 2 and preventing the protective frame 2 from cracking due to excessive local stress.

[0031] To position the positioning plug 5 after installation and prevent it from loosening, this application also features an arc-shaped protrusion 22 protruding downwards on the lower surface of the support protrusion 21, and an arc-shaped groove 51 that matches the arc-shaped protrusion 22 being recessed downwards in the upper middle part of the positioning plug 5. The support protrusion 21 itself is made of a material that can undergo elastic deformation. During the process of the positioning plug 5 passing through the insertion groove 31, the upper side of the positioning plug 5 will exert an upward squeezing force on the arc-shaped protrusion 22. When the arc-shaped groove 51 corresponds to the arc-shaped protrusion 22, the cooperation between the arc-shaped protrusion 22 and the arc-shaped groove 51 can position the positioning plug 5, thereby preventing the positioning plug 5 from sliding in the opposite direction and causing it to detach from the insertion groove 31. In other words, after installation, the positioning plug 5 of this device can maintain a stable position and will not easily loosen. A chamfer 52 is provided at the end corner of the positioning plug 5 to facilitate the positioning plug 5 entering the inner cavity of the insertion groove 31.

[0032] To prevent the clamping plate 4 from damaging the surface of the protective frame 2, the clamping plate 4 of this application is designed as a flat "U"-shaped structure, which can reduce its own weight as much as possible while ensuring its own strength. The two sides of the clamping plate 4 press against the upper surface edges of two adjacent protective frames 2 respectively. A flexible pad 43 is bonded and fixed to the lower surface of the clamping plate 4. The flexible pad 43 is designed to prevent the surface of the protective frame 2 from being damaged. On the other hand, the flexible pad 43 has a certain elastic deformation capability, which can facilitate the positioning plug 5 to pass through the inner cavity of the insertion slot 31.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
