[0069] On the one hand, due to the provision of the outer frame 1, the photovoltaic panel 2 will not be damaged during installation and removal, and by adopting a modular structure for the photovoltaic assembly, the connecting rod assembly 4 is accommodated in the accommodating cavity 3, so that the transportation of the photovoltaic assembly is more convenient; on the other hand, by moving the end of the lever 6 extending out of the lock slot 31 to achieve locking and unlocking of the locking rod 5, the installation and removal of the photovoltaic assembly is more convenient. It can be seen that compared with the prior art, the assembled photovoltaic assembly for construction in the embodiment of the present invention adopts a modular structure, which is more convenient for installation and removal.

[0070] In the embodiment of the present invention, the first direction is specifically a counterclockwise rotation direction, and correspondingly, the second direction is specifically a clockwise rotation direction.

[0071] In the above structure, as a more preferred embodiment, the assembled photovoltaic component for building in the embodiment of the present invention also includes a first elastic member 7, wherein the first elastic member 7 is arranged in the accommodating chamber 3, and the two ends of the first elastic member 7 are respectively connected to the locking rod 5 and the inner wall of the accommodating chamber 3, and under the action of external force, the lever 6 is rotated along the second direction to the unlocking working position, and the locking rod 5 is driven to move into the accommodating chamber 3 through the connecting rod assembly 4, the first elastic member 7 is compressed, thereby realizing the unlocking process, and, when the external force disappears, under the action of the first elastic member 7, the locking rod 5 is pushed through the lock hole 32 to extend out of the accommodating chamber 3, and the connecting rod assembly 4 drives the lever 6 to rotate along the first direction to the locking working position.

[0072] Due to the provision of the first elastic member 7, the locking rod 5 can be kept in a locked state, and the installation of the photovoltaic component is more stable.

[0075] Specifically, when the lever 6 is rotated in the second direction (clockwise rotation direction) to the unlocking working position, the lever 6 rotates around the rotating shaft, driving the third connecting rod 44 to move in the limit block 45, and under the action of the second connecting rod 43, the connecting rod is driven to rotate counterclockwise around the mounting column, and the first connecting rod 42 drives the locking rod 5 to compress the first elastic member 7, and the locking rod 5 moves into the accommodating cavity along the direction of the locking hole 32, thereby realizing the unlocking process. When the external force of the lever 6 is released, under the action of the first elastic member 7, the locking rod 5 is pushed through the locking hole 32 and extends out of the accommodating cavity 3, and drives the first connecting rod 42, the connecting rod 41, the second connecting rod 43, the third connecting rod 44 and the lever 6 to work together, so that the lever 6 rotates in the first direction to the locking working position.

[0076] In the above structure, as a more preferred embodiment, the end of the locking rod 5 in the embodiment of the present invention that passes through the locking hole 32 has a downward inclined surface in the direction away from the connecting rod assembly 4, making it easier for the locking rod 5 to pass through the locking hole 32 and insert the locking rod 5 into the slot.

[0087] In the above method, a ventilation channel is arranged between the decorative panel 500 and the photovoltaic module 100; a ventilation louver 360 connected to the ventilation channel is arranged on the side of the frame 300 away from the base wall 200, and the ventilation louver 360 is used to connect the inside and outside of the ventilation channel, and discharge the hot air to the outside or utilize it through the ventilation channel, thereby reducing the heat generated by the photovoltaic module, reducing the cold load that lowers the indoor temperature in summer, and increasing the power generation of the photovoltaic module.

[0088] In order to more clearly illustrate the installation method in the embodiment of the present invention, the present invention also provides an assembled photovoltaic power generation building.

When the locking rod 5 is in a locked state, the locking rod 5 extends out of the accommodating cavity through the locking hole 32 and is engaged with the slot 320 to achieve the connection between the photovoltaic module and the frame 300, and when the locking rod 5 is in an unlocked state, the locking rod 5 moves into the accommodating cavity through the locking hole 32, which is convenient for loading and unloading the photovoltaic module. Since the photovoltaic module adopts a modular structure, the locking rod 5 can be locked and unlocked by toggling the lever 6, which makes the installation and disassembly of the photovoltaic module more convenient. On the other hand, since the frame 300 is provided with a mounting groove 310, the photovoltaic module is placed in the mounting groove 310 and supported by the frame 300, the service life of the photovoltaic module is extended.

The installation of the photovoltaic component is firm and reliable, and has the ability to resist wind pressure and wind blowing.

[0091] When disassembly is required, the lever 6 is rotated in the lock groove 31 along the second direction to the unlocking working position, the lock rod 5 is retracted into the accommodating cavity 3 through the lock hole 32, and then the lever 6 is pulled outward to allow the photovoltaic component to rotate around the limit rod 330. Since the opening width of the limit groove 9 gradually decreases along the depth direction of the limit groove 9, it is convenient for the limit groove 9 to be separated from the limit rod 330, making disassembly and assembly more convenient.

By setting the insulation layer 400, the material and thickness of the insulation layer 400 can be changed according to the requirements of different climate zones, thereby reducing the heat exchange between the photovoltaic module and the room, having good thermal insulation performance, reducing the energy consumption of indoor air conditioning, and effectively promoting the development of building energy conservation; the decorative panel 500 has good thermal insulation performance, reduces the energy consumption of indoor air conditioning, and can effectively promote the development of building energy conservation; The panel 500 is arranged between the insulation layer 400 and the photovoltaic module, and can play a decorative role; the power generation of the photovoltaic module will decrease as the photovoltaic temperature increases, especially in the summer when the temperature is high and the indoor temperature is greatly affected. Therefore, the photovoltaic module needs to dissipate heat and ventilation in time. A ventilation channel is arranged between the decorative panel 500 and the photovoltaic module in the embodiment of the present invention, and a ventilation louver 360 is arranged on the side of the frame 300 away from the base wall 200. The ventilation louver 360 is used to connect the inside and outside of the ventilation channel, and the hot air is discharged to the outside or utilized through the ventilation channel, thereby reducing the heat generated by the photovoltaic module, reducing the cold load for lowering the indoor temperature in summer, and increasing the power generation of the photovoltaic module.

[0096] The assembled photovoltaic power generation building needs to perform the functions of a building during use, among which waterproofing is an important one. As a more preferred implementation, the ventilation louvers 360 in the embodiment of the present invention are specifically waterproof louvers.

[0097] In the above structure, as a more preferred implementation, the base wall 200 in the embodiment of the present invention may be an exterior wall or a roof wall.

[0098] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
