Description

Technical Field

[0001] The present invention relates to photovoltaic power generation, and particularly to a multifunctional energy-saving photovoltaic building roof structure. Background Art

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photovoltaic effect at the semiconductor interface. The photovoltaic building roof structure refers to a building structure in which a photovoltaic power generation system is installed on the building roof.

[0003] The photovoltaic building roof structure generally includes photovoltaic modules, a support structure, an electrical system, a waterproof system, and a heat dissipation system. When constructing a photovoltaic building roof structure on a higher floor in the city, due to the high floor height, it is difficult for personnel to maintain. However, if the photovoltaic panels are not cleaned for a long time, dust accumulates on the surface of the photovoltaic panels, affecting the power generation efficiency. At the same time, when the floor is high, the wind force is high, and a flat-mounted photovoltaic panel installation structure is generally used to reduce the influence of the wind force.

[0004] In the prior art, the cleaning of photovoltaic panels generally adopts two methods: manual cleaning and natural cleaning. Natural cleaning means that when it rains naturally, the rainwater flushes the photovoltaic panels. However, due to the large influence of the wind force on high-rise buildings, a flat-mounted installation method is generally used, and its natural cleaning effect is poor. At the same time, natural cleaning also depends on the rainfall intensity and rainfall frequency, which is relatively unstable. Manual cleaning is generally carried out by manual labor. However, when the floor is high, the manual cleaning and maintenance cost is high. At the same time, due to the large wind force, manual maintenance is somewhat dangerous, resulting in troublesome cleaning of photovoltaic panels on higher floors. Summary of the Invention

The rotational speed sensor 412 is used to detect the rotational speed of the rotating shaft 404. A controller is provided on the roof of the building. The controller is connected to an external power supply and is in control connection with the rotational speed sensor 412. A protection mechanism controlled by the controller is provided on the mounting base 401.

The extraction pipe 8 is fixedly connected to the dust collection end of the dust collection device 9, and the extraction pipe 8 is provided with a plurality of connecting pipes 7 for fixedly connecting to the air outlet end of the dust collection rack 6.

[0039] Working principle: Under the action of wind power drive, the vertical blade 403 rotates. The rotation of the vertical blade 403 drives the rotation of the rotating shaft 404. The rotation of the rotating shaft 404 drives the rotation of the connecting rod 405 through the meshing connection of the first bevel gear 406 and the second bevel gear 407. The rotation of the connecting rod 405 drives the rotation of the transmission connection frame 408. The transmission connection frame 408 drives the adjacent rotating connection frames 20 on the left and right through the coupling 411. The rotation of the rotating connection frame 20 drives the reciprocating lead screw 19 connected thereto to rotate. The rotation of the reciprocating lead screw 19 drives the first dust brush mounting frame 15 connected thereto to reciprocate left and right under the limiting action of the slide bar 18, thereby driving the dust brush 501 to clean the photovoltaic panel 2, sweeping up or pushing away the larger particulate matter, dirt, and some dust adhering to the surface.

[0040] When the dust collection device 9 is started, it sucks the dust collection rack 6 through the extraction pipe 8 to collect the dust raised by the cleaning of the dust brush 501 above the photovoltaic panel 2. At the same time, when the dust brush 501 approaches the dust collection rack 6, the dust collection rack 6 also sucks the dust of the dust brush 501.

[0041] Thus, the dust brush 501 can be driven to move left and right by wind power to clean the photovoltaic panel 2, thereby saving energy and effectively utilizing wind energy. And when the wind power is too strong, the transmission connection between the wind power drive device 4 and the rotating connection frame 20 can be cut off through the protection mechanism. At the same time, after the dust brush 501 cleans the photovoltaic panel 2, the dust collection assembly is used for dust collection, which improves the dust collection efficiency and avoids the re-deposition of the dust after it is raised. At the same time, it is automatically cleaned, reducing the manual maintenance cost. At the same time, the suction during dust collection can assist in the heat dissipation of the photovoltaic panel 2 and improve the power generation efficiency.

[0042] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above-described exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, in any aspect, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description.
