[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] Reference Figures 1 to 5 The present application discloses a lightweight waterproof and dustproof photovoltaic panel, which includes several photovoltaic panel bodies 1. One side of each body 1 is provided with connector 1 2 and connector 2 3, and the other side is provided with cover plate 1 4, connector 3 5 and connector 4 6. Cover plate 1 4 is located between connector 3 5 and connector 4 6, and cover plate 2 7 is located between connector 2 3 and connector 4 6. Each group of photovoltaic panels is connected by the cooperation of connector 1 2, connector 2 3, connector 3 5 and connector 4 6.

[0027] Connector 2 3 is used to cover one end of connector 1 2 of the first body 1. Connector 3 5 on other photovoltaic panels is used to cover connector 2 3. Connector 4 6 on other photovoltaic panels is used to cover connector 3 5 and apply pressure to it. Cover plate 1 4 is used to cover connector 1 2 of the first photovoltaic panel and apply pressure to it. Cover plate 2 7 is used to cover the gap between adjacent bodies 1.

[0028] The connector 2 is provided with a limiting part 21, a groove 22, a deformation zone 1, an inclined surface 23, and an inclined surface 24. The limiting part 21 is provided on the inclined surface 23 to limit the position of the cover plate 4 on the connector 2. The groove 22 is used to accommodate other fixed structures and form the deformation zone 1. The deformation zone 1 is used to make the connector 2 deform under the pressure of the cover plate 4. The inclined surfaces 23 and 24 are used to guide rainwater away from the cover plate 4. In this embodiment, a screw can be used to pass through the groove 22 to fix the body 1 to other fixed structures. For ease of description, the screw is not shown in the figure.

[0029] The connector 2 3 is provided with a limiting part 2 31, a groove 2 32, a deformation area 2, a limiting surface 1 33, a limiting surface 2 34, and a limiting surface 35. The limiting part 2 31 is used to limit the position of the connector 3 5. The groove 2 32 is used to cooperate with the groove 1 22 to form the deformation area 2. The deformation area 2 is used to make the connector 2 3 deform under the pressure of the connector 4 6. The limiting surface 1 33 is used to prevent the connector 2 3 from sliding between the connector 2 3 and the connector 1 2 on the adjacent body 1. The limiting surface 2 34 prevents the connector 2 3 from sliding between the connector 3 5 on the adjacent body 1. The limiting surface 3 35 prevents the connector 2 3 from sliding between the connector 4 6 on the adjacent body 1.

[0030] Connector 3 5 and connector 4 6 are respectively provided with limiting part 3 51 and limiting part 4 61 that fit into limiting part 2 31. Limiting part 3 51 and limiting part 4 61 are used to cooperate with limiting part 2 31 to make connector 2 3, connector 3 5 and connector 4 6 more firmly connected.

[0031] The cross-sectional shape of connector 1 2 fits with connector 2 3 and cover plate 2 7, the cross-sectional shape of connector 2 3 fits with connector 3 5, and the cross-sectional shape of connector 3 5 fits with connector 4 6.

[0032] The cover plate 4 is provided with an insert 41, which is used to insert into the limiting part 21. The insert 41 is provided with an arc surface, and the shape of the limiting part 21 matches the arc surface.

[0033] When connecting the main body 1, the screw fixes the first main body 1 to the designed position through the groove 22. The second connector 3 covers the first connector 2 on the main body 1. The first connector 2 and the limiting surface 33 on the second connector 3 abut against each other, so that the position of the second connector 3 is limited. The cover plate 7 connected to the second connector 3 covers the gap between adjacent main bodies 1, so that the sealing between adjacent main bodies 1 is better. The screw fixes the second connector 3 to the designed position through the groove 22.

[0034] When the main body 1 in the other direction is connected to the fixed main body 1, the connector 3 5 covers the connector 2 3 on the fixed main body 1. The limiting surface 2 34 on the connector 3 5 abuts against the limiting surface 2 34 on the connector 2 3, so that the position of the photovoltaic panel is limited. The cover plate 4 covers the connector 2 on the adjacent photovoltaic panel. The shape of the cover plate 4 fits the shape of the connector 2, and the protrusion on the cover plate 4 extends into the limiting part 21, so that the connection between the connector 2 and the cover plate 4 is firm and the sealing between the adjacent main bodies 1 is better. The deformation area 1 allows the connector 2 to produce a certain deformation, so that when the pressure applied by the cover plate 4 is applied to the connector 2, the connector 2 can generate a reaction force, thereby making the connection between the connector 2 and the cover plate 4 more firm. The main body 1 is fixed to the design position (such as the bracket) by using a screw through the groove 22.

[0035] Next, the fourth connector 6 covers the third connector 5 on the fixed body 1 and applies force to the third connector 5, so that the third connector 5 applies force to the second connector 3, thereby causing the deformation zone 2 on the second connector 3 to deform. The deformation zone 2 allows the second connector 3 to deform to a certain extent, so that when the pressure applied to the third connector 5 is transmitted to the second connector 3, the second connector 3 can generate a reaction force, thereby making the connection between the second connector 3, the third connector 5 and the fourth connector 6 more secure. Finally, the body 1 is fixed to the designed position by using a screw through the groove 22.

[0036] The implementation principle of this embodiment is as follows: Each group of main bodies 1 is connected by the cooperation of connector 1 2, connector 2 3, connector 3 5 and connector 4 6. The cover plate 1 4 between connector 3 5 and connector 4 6 covers connector 2 on other main bodies 1. The limiting part 1 21 limits the position of cover plate 1 4 on other main bodies 1, so that the two adjacent groups of photovoltaic panels are firmly connected. Through the cooperation of connector 1 2, connector 2 3, connector 3 5 and connector 4 6, the photovoltaic panels can be combined and installed as needed. There is no need to customize a large number of profile keel brackets to install roof photovoltaic panels, which reduces photovoltaic installation costs and shortens the installation cycle.

[0037] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
