The collector component 1 and the collector component 2 2 are sealed and connected by a sealing component 32 matched with the card slot 31. The inner wall of the alloy frame 3 is set as an insulation board 33. There is a cavity between the insulation board 33 and the photovoltaic panel 4.

[0028] In some embodiments, the alloy frame 3 of the collector assembly 1 and the collector assembly 2 2 is fixed by a pressing block assembly 5 to achieve a stable connection between the collector assembly 1 and the collector assembly 2 2; in addition, the side end of the alloy frame 3 connected to the collector assembly 1 and the collector assembly 2 2 is sealed by a sealing assembly 32 matched with the card slot 31, which reduces the heat energy loss between the collector assemblies and also plays a role in stabilizing the connection of the collector assemblies; the setting of the insulation board 33 can effectively reduce the cavity heat energy loss between the photovoltaic panel 4 and the insulation board 33, and the photovoltaic panel 4 and the alloy frame 3 are fixed and sealed by gluing to prevent air leakage.

[0029] Reference Figure 2 The pressing block assembly 5 is configured as a fixed pressing block 51 and a fixing screw 52, ​​and the fixed pressing block 51 and the fixing screw 52 are matched and configured. The fixed pressing block 51 is used to fix the alloy frame 3 connected to the collector assembly 1 and the collector assembly 2 2, and the fixing screw 52 is used to press and firmly fix the alloy frame connected to the pressing block 51.

[0030] In some embodiments, the alloy frames 3 of the collector assembly 1 and the collector assembly 2 are fixed by means of a fixed pressure block 51 provided in the pressure block assembly 5, and then a fixing screw 52 provided in conjunction with the fixed pressure block 51 is inserted into the fixed pressure block 51 and the fixing screw 52 is tightened to achieve a stable connection between the corresponding alloy frames 3 of the collector assembly 1 and the collector assembly 2, which is not only convenient to operate but also can make the connection between the collector assemblies more stable.
