Description

Technical Field

[0001] This utility model relates to the field of construction, specifically to an adjustable photovoltaic sunshade. Background Technology

[0002] Energy and energy conservation have become a hot topic of discussion in the world today. In my country, the high energy consumption of winter heating and summer cooling, as well as the corresponding high cost of buildings and equipment, require buildings to adapt to climate change and achieve adaptability through the building's external interface.

[0003] Modern buildings, especially large office buildings, often use large windows or even glass curtain walls to maximize the use of sunlight to improve the indoor environment. This requires certain shading measures to be taken at the beginning of the design. At the same time, sunshades can prevent glare from direct sunlight and local overheating of the room, thus improving the indoor lighting environment.

[0004] In existing technologies, building exterior shading is categorized by form into: horizontal shading, vertical shading, combined shading, and baffle shading. Among these, horizontal shading is the most widely used and most effective, capable of blocking sunlight at a relatively high angle. While existing horizontal shading can effectively block sunlight during periods of intense sunshine, it does not reach its maximum effectiveness at other times. Furthermore, when the sun's angle is low, it can negatively impact the indoor lighting environment, affecting indoor illumination. Existing shading technologies suffer from the following problems:

[0005] 1. Existing sunshades have fixed angles. Under low irradiance conditions (such as cloudy days, early morning, or dusk), fixed-angle sunshades will excessively block natural light, forcing the use of artificial lighting indoors and increasing building energy consumption.

[0006] 2. Existing sunshades have limited functionality;

[0007] 3. Since the sunshade is suspended outside the building, the cost of cleaning and maintenance is relatively high. Utility Model Content

[0008] The purpose of this invention is to provide an energy-saving and easy-to-maintain adjustable photovoltaic sunshade.

[0009] In this embodiment of the utility model, an adjustable photovoltaic sunshade is provided, comprising: a corner embedded part fixed to the civil engineering beam of a building balcony, an electrically controlled rotating shaft fixed to the corner embedded part, a photovoltaic module fixed to the electrically controlled rotating shaft, a light monitoring device and a control device installed on the exterior wall of the building, wherein the control device is connected to the light monitoring device and the electrically controlled rotating shaft, and is used to control the rotation angle of the electrically controlled rotating shaft according to the solar altitude angle of the light monitoring device.

[0010] In this embodiment of the invention, the adjustable photovoltaic sunshade also includes a cleaning device disposed above the photovoltaic sunshade and an air quality monitoring device disposed on the building, wherein the air quality monitoring device and the cleaning device are respectively connected to the control device.

[0011] In this embodiment of the invention, the adjustable photovoltaic sunshade also includes a manual operating device electrically connected to the electrically controlled rotating shaft.

[0012] In this embodiment of the utility model, the photovoltaic module includes a steel plate frame and a photovoltaic panel, and the photovoltaic panel is fixed to the steel plate frame by stainless steel bolts.

[0013] In this embodiment of the invention, the adjustable photovoltaic sunshade also includes a power supply device, which is connected to the photovoltaic panel, the electronically controlled rotating shaft, and the control device.

[0014] Compared with existing technologies, the adjustable photovoltaic sunshade of this invention collects outdoor light environment parameters and measures the solar altitude angle through a light monitoring device installed on the exterior wall of the building. This information is then transmitted to the control system, which drives the sunshade to rotate to a set position via a pivot, achieving optimal sun shading. The photovoltaic panel generates electricity using the shading surface of the sunshade and is connected to a power supply device via wires, automatically powering the entire system. An air quality monitoring device monitors outdoor PM2.5, PM10, dust, and particulate matter. When these values ​​exceed a certain threshold, the control system activates a cleaning device to clean the photovoltaic sunshade, reducing dust accumulation and its impact on power generation efficiency. The adjustable photovoltaic sunshade also includes a manual operating device electrically connected to the control pivot, which can replace the automatic control system for manual control when necessary. This method also ensures that the sunshade does not rotate accidentally during maintenance or inspection. Attached Figure Description

[0020] The light monitoring device 14 is used to collect outdoor light environment parameters, measure the solar altitude angle, and transmit the information to the control device 15. The control device 15 controls the rotation angle of the electrically controlled shaft 12 based on the solar altitude angle measured by the light monitoring device 14, thereby driving the photovoltaic module 13 to rotate to a set position to achieve the best sun-blocking effect. The electrically controlled shaft 12 may include a motor, and the rotation angle is controlled by the movement of the motor.

[0021] In this embodiment of the invention, the photovoltaic module 13 includes a steel plate frame 131 and a photovoltaic panel 132, wherein the photovoltaic panel 132 is fixed to the steel plate frame 131 by stainless steel bolts 133.

The air quality monitoring device 16 and the cleaning device 17 are respectively connected to the control device 15. The air quality monitoring device 16 is used to monitor outdoor PM2.5, PM10, dust, and particulate matter. When the measured value exceeds the set value, the control device 15 will activate the cleaning device 17 to clean the photovoltaic sunshade, reducing dust and other pollutants covering the photovoltaic sunshade and affecting its power generation efficiency.

[0023] Furthermore, in this embodiment of the invention, the adjustable photovoltaic sunshade also includes a manual operating device 18 electrically connected to the electrically controlled rotating shaft 12. The manual operating device 18 is used to replace the control device 15 for manual operation, so as to ensure that the photovoltaic sunshade will not rotate accidentally during maintenance or inspection.

[0024] Furthermore, in this embodiment of the present invention, the adjustable photovoltaic sunshade also includes a power supply device 19, which is connected to the photovoltaic panel 132, the electrically controlled rotating shaft 12, and the control device 15. The power supply device 19 is used to store the electrical energy generated by the photovoltaic panel 132 and to supply power to the control device 15, the electrically controlled rotating shaft 12, the light monitoring device 14, the air quality monitoring device 16, and the cleaning device 17.

[0025] In summary, the adjustable photovoltaic sunshade of this invention collects outdoor light environment parameters and measures the solar altitude angle through a light monitoring device installed on the exterior wall of the building. This information is then transmitted to the control system, which drives the sunshade to rotate to a set position via a pivot, achieving optimal sun shading. The photovoltaic panel generates electricity using the shading surface of the sunshade and is connected to a power supply device via wires, automatically powering the entire system. The air quality monitoring device monitors outdoor PM2.5, PM10, dust, and particulate matter. When these values ​​exceed a certain threshold, the control system activates a cleaning device to clean the photovoltaic sunshade, reducing dust accumulation and its impact on power generation efficiency.
