[0036] A first cover plate 4 is provided between the third connecting member 5 and the fourth connecting member 6, and a second cover plate 7 is provided between the second connecting member 3 and the fourth connecting member 6. The first cover plate 4 on the B1 body 13 is used to cover the first connecting member 2 on the A1 body 11. The first cover plate 4 on the B2 body 14 is used to cover the first connecting member 2 on the A2 body 12. An extending member 41 is provided on the first cover plate 4. The extending member 41 is used to extend into the first limiting portion 21. An arc surface is provided on the extending member 41. The shape of the first limiting portion 21 is matched with the arc surface. The second cover plate 7 is used to cover the gap between group A or group B of photovoltaic panel bodies 1.

[0037] The first connecting member 2 is provided with a first limiting portion 21, a first groove 22, a first inclined surface 23 and a second inclined surface 24. The first limiting portion 21 is arranged on the first inclined surface 23. The first limiting portion 21 on the A1 body 11 is used to limit the position of the first cover plate 4 on the B1 body 13 on the first connecting member 2, and the first limiting portion 21 on the A2 body 12 is used to limit the position of the first cover plate 4 on the B2 body 14 on the first connecting member 2. The first groove 22 is used to accommodate other fixing structures and form a first deformation area. The first deformation area is used to make the first connecting member 2 generate a certain deformation under the pressure of the first cover plate 4. In this embodiment, the other fixing structure can adopt a screw. For the convenience of description, the screw is not shown in the figure.

[0038] The second connecting member 3 is provided with a second groove 32, a second limiting portion 31, a first limiting surface 33, a second limiting surface 34 and a third limiting surface 35. The second groove 32 is used to be attached to the first groove 22 to form a second deformation area. The second deformation area is used to make the second connecting member 3 generate a certain deformation under the pressure of the fourth connecting member 6. The second limiting portion 31 on the A2 body 12 is used to limit the position of the third connecting member 5 on the B1 body 13. The first limiting surface 33 is used to prevent sliding between the second connecting member 3 on the two photovoltaic panel bodies 1 and the first connecting member 2. The second limiting surface 34 is used to prevent sliding between the second connecting member 3 on the A2 body 12 and the third connecting member 5 on the B1 body 13. The third limiting surface 35 is used to prevent sliding between the second connecting member 3 on the A2 body 12 and the fourth connecting member 6 on the B2 body 14.

[0039] The third connecting member 5 and the fourth connecting member 6 are respectively provided with a third limiting portion 51 and a fourth limiting portion 61 that are attached to the second limiting portion 31. The third limiting portion 51 on the B1 body 13 and the fourth limiting portion 61 on the B2 body 14 are used to cooperate with the second limiting portion 31 on the A2 body 12 to make the connection between the second connecting member 3, the third connecting member 5 and the fourth connecting member 6 more firm.

[0040] The cross-sectional shape of the first connecting member 2 fits with the second connecting member 3 and the second cover plate 7. The cross-sectional shape of the second connecting member 3 fits with the third connecting member 5. The cross-sectional shape of the third connecting member 5 fits with that of the fourth connecting member 6.

[0041] When connecting the photovoltaic panel body 1, the screw is passed through the first groove 22 to fix the A1 body 11 to the designed position. The second connecting member 3 on the A2 body 12 covers the first connecting member 2 on the A1 body 11. The second cover plate 7 on the A2 body 12 covers the A1 body 11. The shapes of the first connecting member 2 and the second connecting member 3 fit with each other, so that the contact between the A1 body 11 and the A2 body 12 is sealed. The first limiting surface 33 on the first connecting member 2 and the second connecting member 3 abuts against each other, so that the position of the A2 body 12 is limited, thereby making the position of the A2 body 12 more accurate.

[0042] After the A2 body 12 is completely fixed, the cover plate one 4 and the connecting piece three 5 of the B1 body 13 cover the connecting piece one 2 of the A1 body 11 and the connecting piece two 3 of the A2 body 12. The protruding piece on the cover plate one 4 and the limiting part one 21 cooperate to limit the positions of the cover plate one 4 and the connecting piece one 2. The limiting surface two 34 on the connecting piece two 3 limits the position of the connecting piece three 5, preventing sliding between the A1 body 11 and the B1 body 13, so that the position of the A2 body 12 is more accurate. The deformation area one enables the connecting piece one 2 to generate a certain deformation, so that when the pressure applied by the cover plate one 4 acts on the connecting piece one 2, the connecting piece one 2 can generate a reaction force, making the connection between the connecting piece one 2 and the cover plate one 4 more firm.

[0043] After the B1 body 13 is completely fixed, a part of the A2 body 12 and the B1 body 13 is covered by the B2 body 14. Among them, the connecting piece four 6 on the B2 body 14 covers the connecting piece three 5 on the B1 body 13. Since the connecting piece four 6 and the connecting piece three 5 are in contact, the sealing performance between the two is better. The limiting surface three 35 on the A2 body 12 limits the position of the connecting piece four 6, making the position of the B2 body 14 more accurate.

[0048] Step three:

[0049] Installation steps of the B1 body 13: Make the cover plate one 4 and the connecting piece three 5 on the B1 body 13 cover the connecting piece one 2 on the A1 body 11 and the connecting piece two 3 on the A2 body 12 respectively, so that the protruding piece on the cover plate one 4 extends into the limiting part one 21 of the connecting piece one 2, and the limiting surface two 34 on the connecting piece three 5 and the connecting piece two 3 are in contact, so that the position of the B1 body 13 is limited, and fix the B1 body 13;

[0050] Step three:

[0051] Installation steps of B2 body 14: Connector 2 3, cover plate 1 4, connector 4 6 and cover plate 2 7 on B2 body 14 are respectively covered to connector 3 5 on A1 body 11, connector 1 2 on A2 body 12, connector 3 5 on B1 body 13 and the gap between B1 body 13 and B2 body 14, so that the limiting surface 3 35 on A2 body 12 and connector 4 6 on B2 body 14 are in conflict, so that the position of B2 body 14 is limited, and B2 body 14 is fixed by a fixing structure, so that the B group of photovoltaic panels is assembled;

[0052] Step 4:

[0053] Steps for testing the sealing between the connector three 5 and the connector four 6: The connector three 5 and the connector four 6 are combined to form a storage slot 8. During the splicing process, the surface of the connector three 5 is coated with an adhesive. The connector four 6 is covered on the connector three 5, and the opening of the storage slot 8 is downward, so that the adhesive overflows from the gap between the connector three 5 and the connector four 6. Then, the photovoltaic panel bodies 1 of the group A and the group B are tilted so that the opening of the storage slot 8 is upward (refer to Figure 3 ), so that the overflowed adhesive is stored in the storage tank 8, and whether the sealing between the connecting piece three 5 and the connecting piece four 6 is qualified is judged by observing the drop of the liquid level of the adhesive in the storage tank 8 within a certain period of time.

[0054] Step 5: Use a hot air dryer or other equipment to accelerate the curing of the adhesive in the storage tank 8, so that the connecting piece 3 5 and the connecting piece 4 6 are firmly connected, and the gap between the two is filled densely.

[0055] The implementation principle of this embodiment is: connector 1 2, connector 2 3, connector 3 5 and connector 4 6 cooperate to complete the buckle connection, the cover plate 4 between connector 3 5 and connector 4 6, the cover plate 4 covers the connector 2 of A1 body 11 and the limiting part 21 on connector 2 limits the position of cover plate 4 on connector 2, so that the adjacent A and B groups of photovoltaic panels are firmly connected, and the photovoltaic panels can be combined and installed according to needs through the cooperation of connector 1 2, connector 2 3, connector 3 5 and connector 4 6, without the need to customize a large number of profile keel brackets to install roof photovoltaic panels, so that the photovoltaic installation cost is reduced and the installation period is shortened.
