[0041] Example 1

[0042] This embodiment provides a photovoltaic power generation roof module, such as Figures 1 to 6 As shown, the photovoltaic roof module includes a base member 1, a roof member 2, a photovoltaic member 3, a thermal break connector 4, a locking member 5, an assembly connector, and an edge seal 8. The base member 1, the roof member 2, and the photovoltaic member 3 are arranged in sequence in a direction away from the interior.

[0043] like Figure 1 and Figure 2 As shown, the thermal break connector 4 is installed inside the photovoltaic roof module and includes a thermal break insulation member 41 and a reinforcing support member 42. The thermal break insulation member 41 is connected to the base member 1, and the reinforcing support member 42 is connected to the thermal break insulation member 41 and also to the roof member 2. The first connecting protrusion 422 of the reinforcing support member 42 overlaps the second connecting protrusion 411 of the thermal break insulation member 41, and the two are connected by fasteners such as rivets.

[0044] By setting up a reinforcing support member 42, the reinforcing support member 42 can improve the strength of the thermal break connector 4, thereby improving the wind pressure resistance of the lock edge fitting portion 421 on the thermal break connector 4 connected to the roofing member 2, thereby improving the wind resistance of the photovoltaic roof module, and preventing the roofing member 2 from falling off when encountering strong winds. By setting up a first connecting protrusion 422 of the reinforcing support member 42 to overlap the second connecting protrusion 411 of the thermal break insulation member 41, the stability of the connection between the reinforcing support member 42 and the thermal break insulation member 41 can be improved.

[0045] like Figure 4 As shown, the roofing member 2 is provided with a locking portion 21, and the locking portion 421 of the reinforcing support member 42 is located in the locking portion 21. The locking portion 21 passes through the interval between adjacent photovoltaic members 3 and is located on the side of the photovoltaic member 3 away from the roofing member 2.

The locking member 5 includes a first clamping member 51 and a second clamping member 52, which are rotatably connected to each other. A fastener such as a bolt is connected between the first clamping member 51 and the second clamping member 52 to fix the first clamping member 51 and the second clamping member 52 to clamp the locking portion 21.

[0046] By providing a locking portion 21, the stability of the connection between adjacent roofing members 2 can be improved, and gaps between adjacent roofing members 2 can be prevented to avoid water leakage; by providing a first clamping member 51 and a second clamping member 52 on the locking portion 21, a fastener is connected between the first clamping member 51 and the second clamping member 52, and the first clamping member 51 and the second clamping member 52 are moved toward the side close to the locking portion 21 by the fastener, thereby fixing the locking portion 21 and preventing the locking portion 21 from shaking; the locking portion 21 is provided through the interval on the side of the photovoltaic member 3 away from the roofing member 2, which can facilitate the installation of the locking member 5 and enable the locking member 5 to fix the photovoltaic member 3.

[0047] like Figure 1 and Figure 5 As shown, the assembling connectors in this embodiment are arranged at the splicing edges of the photovoltaic power generation roof modules. The assembling connectors include a first assembling connector 6 and a second assembling connector 7.

By providing the first assembling connector 6 and the second assembling connector 7, the connection of adjacent photovoltaic power generation roof modules can be facilitated, thereby improving the on-site installation efficiency of the photovoltaic power generation house.

[0048] like Figure 3 、 Figure 5 and Figure 6 As shown, the first assembling connector 6 is a first heat-insulating assembling component, which is connected to the photovoltaic roof module and has a first snap-fitting portion 61 , which is snap-fitted to the second assembling connector 7 .

[0049] By setting the first assembling connector 6 as the first heat-insulating assembling component, the heat on the roofing component 2 can be blocked from being transferred to the base component 1, so as to prevent the indoor temperature of the photovoltaic power generation room from being affected by the temperature of the roofing component 2.

[0050] like Figure 3 、 Figure 5 and Figure 6As shown, the second assembling connector 7 includes a second assembling body 71 and an assembling clip 72. The second assembling body 71 is connected to the photovoltaic power generation roof module. The assembling clip 72 is connected to the second assembling body 71 and the assembling clip 72 has a second snap-fitting portion 721. The second snap-fitting portion 721 is snap-fitted to the first snap-fitting portion 61. By setting the assembling clip 72 to be connected to the second assembling body 71 and the second snap-fitting portion 721 to be snap-fitted to the first snap-fitting portion 61, the first assembling connector 6 and the second assembling connector 7 can be quickly connected. Among them, a mounting hole can be provided at the bottom of the assembling clip 72, and a fastener such as a screw or bolt can be provided in the mounting hole to fix the second assembling connector 7 to the roof beam or purlin. The assembling clip 72 can also be welded and fixed to the roof beam or purlin.

[0051] Among them Figure 3 and Figure 6 As shown, the second assembly body 71 includes a second thermal insulation assembly 711 and a reinforcement support assembly 712 arranged in sequence along the direction away from the room.

[0052] By setting up the second thermal insulation assembly 711 and the reinforced support assembly 712, the second thermal insulation assembly 711 can block the heat from the roofing member 2 from being transferred to the base member 1, preventing the indoor temperature of the photovoltaic power generation house from being affected by the temperature of the roofing member 2; and the reinforced support assembly 712 can increase the strength of the second assembly body 71, preventing the second assembly body 71 from being deformed and damaged under the pressure of the roofing member 2.

[0053] like Figure 1 As shown, a thermal insulation member 9 is provided between the base member 1 and the roofing member 2. The thermal insulation member 4 penetrates the thermal insulation member 9 in the direction from the base member 1 to the roofing member 2. The thermal insulation member 4 can connect the base member 1, the thermal insulation member 9, and the roofing member 2 into one. The thermal insulation member 9 can insulate the photovoltaic power generation roof module. The thermal insulation member 9 includes a first sound insulation member 91, a thermal insulation member 92, and a second sound insulation member 93.

The heat insulation member 92 can prevent heat from the roof member 2 from being transferred to the interior of the photovoltaic power generation room through the heat insulation member 9, thereby preventing the indoor temperature from being affected by the temperature of the roof member 2. The heat insulation member 92 can be a vacuum insulation panel or other material.

[0054] like Figure 1 As shown, edge seals 8 are installed at the spliced ​​edges of the photovoltaic roof modules. Specifically, one end of edge seal 8 is connected to insulation 9, and the side away from insulation 9 is connected to roofing member 2 and second assembly connector 7. Edge seals 8 prevent gaps that could lead to water leaks. Edge seals 8 are made of polyurethane or other materials.

[0055] In the installation process of a photovoltaic power generation roof module in this embodiment, during on-site installation, first determine the installation position of the assembling clip 72, and fix the assembling clip 72 to the roof beam or purlin through bolts and other fixing parts. After the installation of the assembling clip 72 is completed on all roof beams or purlins from the ridge to the eaves, the photovoltaic power generation roof module is hoisted to the predetermined position, and the assembling clip 72 is connected to the second assembling body 71 through fixing parts such as screws. Then, the first assembling connector 6 on one of the photovoltaic power generation roof modules is clamped with the assembling clip 72 on the other photovoltaic power generation roof module, thereby completing the connection of the bottom of the two photovoltaic power generation roof modules, and then the locking parts 21 on the two photovoltaic power generation roof modules are connected to complete the connection of the top of the two photovoltaic power generation roof modules. Finally, the locking part 5 is clamped to the locking part 21 to complete the fixation of the locking part 21.
