Description

Technical Field

[0001] The utility model relates to the technical field of building integrated photovoltaics, in particular to a matrix-type photovoltaic curtain wall and a building body based on individual control. Background Art

[0002] As a carbon emission source, the building field accounts for half or more of the carbon emissions of each country. In the context of energy conservation and emission reduction, it is necessary to reduce carbon emissions. Combining buildings with photovoltaics can effectively reduce the carbon emissions of the construction industry through the characteristics of solar energy being pollution-free and zero-emission. Building integrated photovoltaics is a technology that integrates solar power generation products into buildings. Photovoltaic curtain walls can convert light energy into electrical energy and utilize solar power while providing sunshade. Affected by environmental factors, it is essential to control the switching of photovoltaic curtain walls. Existing technologies mainly focus on controlling the angle of photovoltaic curtain walls to receive more solar energy, while ignoring the influence of the environment, and the rigid photovoltaic glass curtain walls used cannot well control their working conditions in the external environment.

[0003] In the prior art, there is a lack of flexible control of photovoltaic curtain walls. Photovoltaic curtain walls are all fixed by frames. Some photovoltaic curtain walls are fixed and cannot be opened, and most of them are rigidly exposed in the external environment, which easily reduces their service life due to environmental factors.

[0026] The embodiment of the present invention provides an intelligent flexible photovoltaic curtain wall matrix, which is a device for absorbing solar energy and converting it into electrical energy. In this solution, one row in the overall flexible photovoltaic curtain wall matrix of n rows and m×N columns is evenly divided into N individual modules, and each individual module can be controlled independently.

[0027] Specifically, referring to Figure 1 , the matrix-type photovoltaic curtain wall based on independent control includes a first photovoltaic module, a second photovoltaic module,... a Nth photovoltaic module, a first transmission mechanism, a second transmission mechanism,... a Nth transmission mechanism, and a total controller. Each transmission mechanism includes a first motor and multiple second motors. The first photovoltaic module is connected to the first transmission mechanism, the Nth photovoltaic module is connected to the Nth transmission mechanism, and the first motor and the second motors are connected to the total controller.

[0028] The total controller is electrically connected to the motors of each photovoltaic module to control the lifting of each individual photovoltaic module. Transmission mechanism: Combine m flexible photovoltaic glass units to form N individual modules, and transfer the motion brought by the rotation of the motor, so that each individual flexible photovoltaic curtain wall module can be lifted independently.

[0029] As a specific embodiment, referring to Figure 2, the transmission mechanism includes: motor 1, worm 2, worm gear 3, driving shaft 4, driving gear 5, planetary gear 6, planet carrier 7, motor 8, driven gear 9, driven shaft 10, drum 11, photovoltaic unit 12 and coupling 13. Motor 1 serves as the first motor and is used to drive the driving shaft to rotate. Motor 8 serves as the second motor and is used to drive the planet carrier to rotate. Both motor 1 and motor 8 are electrically connected to the main controller. A worm 2 is provided on the output shaft of motor 1 to transmit the motor speed, and the worm 2 meshes with the worm gear 3. The worm gear 3 is fixedly connected to the driving shaft 4, and the worm gear 3 drives the driving shaft 4 to rotate together. The driving shaft 4 is also fixedly connected to the driving gear 5. Using the driving gear 5 as the sun gear, the planetary gear 6 meshes with the gear 5 and orbits. The planetary gear 6 is controlled by the planet carrier 7 powered by the motor 8. A drum 11 is provided on the driven shaft 10, and the driven gear 9 is fixedly connected to the drum 11 and can mesh with the planetary gear 6. The photovoltaic unit 12 is flexible photovoltaic glass, and the drum 11 is fixedly connected to the flexible photovoltaic glass. Each individual module is provided with m drums 11 and m flexible photovoltaic glasses fixedly connected thereto, and a coupling 13 is provided between every two drums. Correspondingly, there are m planetary gears 6, planet carriers 7, motors 8 and couplings 13 corresponding to the drums 11 and the flexible photovoltaic glasses.

[0030] In the present utility model, for the overall photovoltaic curtain wall matrix, each row contains n flexible photovoltaic glasses, and there are m×N columns in total. It is divided into N individual modules. Each individual module contains the same flexible photovoltaic glass lifting system. The motors 1 and 8 in each lifting system are electrically connected to the main controller. The main controller controls the forward and reverse rotation of the motor 1 to provide power for the lifting of the photovoltaic curtain wall; the main controller controls the start of the motor 8 to make the planetary gear 6 mesh with or disengage from the driven gear 9 to achieve the lifting of different flexible photovoltaic glasses, thereby realizing the individual control of each flexible photovoltaic glass.

[0031] During specific operation, the main controller controls the on-off of the forward and reverse rotation of the motor in each module, and controls the motor in the flexible glass lifting system that needs to be lifted or lowered. Driven by the motor 1, the worm 2 rotates and meshes with the worm gear 3. The worm and worm gear provide the power required for the system to transmit motion and provide the self-locking condition. The rotation of the worm gear 3 drives the driving shaft 4 to rotate, and the driving gear 5 provides the power. The motor 8 controls the rotation of the planet carrier 7 to make the planetary gear 6 mesh with the driven gear 9, transmits the motion of the driving gear 5 to make the drum 11 rotate, and achieves the lifting of the flexible photovoltaic glass. The coupling 13 connects the driven shafts 10 between each drum, provides displacement compensation ability, and improves the dynamic performance of the shafting. When only the lifting of a certain individual flexible photovoltaic glass needs to be controlled, the main controller controls the rotation of the motor 8 to rotate the planet carrier 7 to achieve the meshing or disengagement of the planetary gear 6 and the driven gear 9.

[0032] The utility model divides the photovoltaic curtain wall into multiple separate modules, and can independently control the lifting of each flexible photovoltaic glass, improving the efficiency of controlling the lifting of the matrix flexible glass curtain wall in a building. Meanwhile, the inspection and maintenance efficiency when the photovoltaic curtain wall is damaged is improved. On the other hand, using a roller to retract the flexible glass can avoid the problem of affecting its service life due to long-term exposure of the photovoltaic glass to the environment.
