Description

Technical Field

[0001] The utility model relates to the field of photovoltaics, in particular to an adjustable photovoltaic curtain wall. Background Art

[0002] Photovoltaic curtain wall is a curtain wall form that replaces the building curtain wall panels with photovoltaic curtain wall components with power generation function, which perfectly embodies the concept of sustainable development and achieves the goal of carbon reduction. Most of the existing photovoltaic panels are fixed by frames and integrated with crystalline silicon or thin-film photovoltaic panels on the facade of the building. However, due to the change in the angle of sunlight during the day, most of the existing photovoltaic panels are fixed on the facade, resulting in reduced power generation efficiency and failure to fully utilize the photovoltaic panels for power generation.

[0003] In addition, photovoltaic curtain walls generate or absorb heat when working, causing the temperature inside the curtain wall to rise. If the heat cannot be effectively dissipated, it is easy to cause the components to overheat and burn out. At the same time, there is also a risk of fire due to excessive local temperature. The needs of buildings are inconsistent throughout the year, especially in winter and summer. The existing photovoltaic curtain walls cannot adapt well to the various needs of users and have certain limitations. Utility Model Content

BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the closed state of the adjustable photovoltaic curtain wall in an embodiment of the utility model.

[0014] Figure 2 It is a structural schematic diagram of the opening state of the adjustable photovoltaic curtain wall in an embodiment of the utility model. DETAILED DESCRIPTION

[0015] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0016] The implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0017] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, an adjustable photovoltaic curtain wall is provided, which includes a transverse bracket 2 extending from the bottom end of a vertical beam 1 above the balcony on the current floor of the building, a first bracket 3 connected between the end of the transverse bracket 2 and the top of the vertical beam 1, and a second bracket 5 connected between the end of the transverse bracket 2 and the outer edge of the balcony ground 4 on the current floor. It should be noted that in a building with a balcony, a vertical beam for bearing weight is usually arranged on the outer side of the top of the balcony.

[0018] The first bracket 3 is provided with a first photovoltaic panel 31. The first photovoltaic panel 31 adopts a crystalline silicon cell photovoltaic panel. The angle between the first photovoltaic panel 31 and the horizontal ground is the optimal photovoltaic tilt angle of the local area. It should be noted that since the first photovoltaic panel 31 is located on the outside of the vertical beam 1, there is no need to consider the line of sight factor. It can use a crystalline silicon cell that is opaque but has high power generation efficiency, and its tilt angle should be matched with the optimal photovoltaic tilt angle of the local area as much as possible, so that the photovoltaic power generation panel can fully absorb sunlight to obtain the maximum power generation. The photovoltaic tilt angle is the angle between the plane of the photovoltaic panel and the horizontal ground. The optimal photovoltaic tilt angle in a year is related to the local geographical latitude. When the latitude is higher, the corresponding tilt angle is also larger.

[0019] The second bracket 5 is provided with a second photovoltaic panel 51. The second photovoltaic panel 51 includes an upper photovoltaic panel 511 and a lower photovoltaic panel 512 which are hinged to each other. A guide rail 52 is provided on the second bracket 5. The bottom end of the lower photovoltaic panel 512 is fixed on the guide rail 52 and can move on the guide rail 52. A control box 53 is also provided on the top of the second photovoltaic panel 51. The control box 53 is connected to the bottom end of the lower photovoltaic panel 512 and is used to control the position of the bottom end of the lower photovoltaic panel 512. Specifically, the control box 53 can be connected to the bottom end of the lower photovoltaic panel 512 through a pull rope (not shown in the figure). The position of the bottom end of the lower photovoltaic panel 512 is controlled by controlling the length of the pull rope, thereby controlling the state of the second photovoltaic panel 51. When ventilation is needed, the lower photovoltaic panel 512 can be pulled so that the second photovoltaic panel 51 is in an open state, such as Figure 2 When heat collection is required, the lower photovoltaic panel 512 can be retracted so that the second photovoltaic panel 51 is in a closed state, such as Figure 1 shown.

[0020] Furthermore, in the embodiment of the utility model, the second photovoltaic panel 51 adopts a thin-film photovoltaic panel, and when in the off state, the angle between the second photovoltaic panel 51 and the horizontal ground is 75 degrees. It should be noted that since the second photovoltaic panel 51 is located under the beam, it is necessary to consider the line of sight and the light transmission effect, and a semi-transparent thin-film battery with slightly lower power generation efficiency is selected, and the angle between the thin-film battery and the horizontal ground is 75 degrees, thereby reducing the radiation and glare of direct sunlight. And due to the weak light property of the thin-film battery, it can achieve a stable power supply even in bad weather.

[0021] To summarize, by adopting the adjustable photovoltaic curtain wall of the utility model, a first photovoltaic panel is arranged on the first bracket, which can achieve maximum power generation when the sunshine conditions are good. In addition to supplying its own energy demand, the surplus electricity can be returned to the state grid; a second photovoltaic panel is arranged on the second bracket, and the second photovoltaic panel includes an upper photovoltaic panel and a lower photovoltaic panel hinged to each other, and a guide rail is arranged on the second bracket. The bottom end of the lower photovoltaic panel is fixed on the guide rail and can be moved on the guide rail. The coverage degree of the photovoltaic panels on the facade of the building can be controlled by adjusting the shape of the second photovoltaic panel, so as to adapt to weather changes and meet the needs of users, and can respond quickly according to environmental changes or the needs of indoor personnel to reduce energy consumption, improve the energy efficiency of buildings, and better achieve the goals of building energy conservation and emission reduction.

[0022] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
