Description

Technical Field

[0001] This utility model belongs to the field of photovoltaic technology, specifically relating to an intelligent BIPV photovoltaic system. Background Technology

[0002] Currently, known photovoltaic curtain wall structures are fixed building forms with unstable power generation efficiency. At the same time, the angle of photovoltaic modules and the light transmittance of the system cannot be adjusted, and the working status cannot be adjusted according to the actual use requirements of the building to achieve intelligent control and optimization of indicators such as power generation, light transmittance, and temperature.

[0003] This application provides an intelligent BIPV photovoltaic system with many functions such as heat insulation, light transmission, ventilation, rain protection, and heat preservation. At the same time, the novel algorithm logic ensures the intelligent and unified control of green buildings, reducing building energy consumption while generating electricity, thus achieving the goal of energy conservation and emission reduction. Utility Model Content

[0004] The present invention aims to overcome the shortcomings of the prior art and provide an intelligent BIPV photovoltaic system.

[0005] This utility model is achieved through the following technical solution:

[0006] An intelligent BIPV photovoltaic system includes a rotatable photovoltaic unit, a pusher, an insulated water tank, and a sensor module;

[0007] Multiple rotatable photovoltaic units are arranged in a rectangular array on the main steel frame structure of the building roof. A pusher and an insulated water tank are installed below each row of adjacent rotatable photovoltaic units. The pusher is vertically installed on the main steel frame structure, and the insulated water tank is installed on the top of the pusher. The pusher can drive the water tank to move up and down to adjust its vertical position. The sensor module is installed on the main steel frame structure.

[0008] In the above technical solution, the rotatable photovoltaic unit includes two rotatable and adjustable photovoltaic panel mechanisms arranged in a centrally symmetrical manner. Each rotatable and adjustable photovoltaic panel mechanism includes a photovoltaic panel, a bushing, a rotating shaft, a bearing support, a gear, and a motor.

[0009] In the above technical solution, the two ends of the rotating shaft are mounted on the main steel frame structure through bearing support components, the motor is fixedly mounted on the main steel frame structure, the output shaft of the motor is connected to the gear on the rotating shaft through transmission, and thus the rotating shaft can be driven to rotate by the motor; the bushing is fixedly connected to the rotating shaft, and the photovoltaic panel is fixedly connected to the bushing.

[0010] In the above technical solution, the heat-insulating water tank is a rectangular tank, which includes a bottom plate, two first side walls and two second side walls. The two first side walls are fixedly connected to the front and rear sides of the bottom plate, and the two second side walls are fixedly connected to the left and right sides of the bottom plate.

[0011] In the above technical solution, the bottom surface of the photovoltaic panel of the rotatable adjustable photovoltaic panel mechanism of the rotatable photovoltaic unit is provided with a strip-shaped snap-fit ​​groove corresponding to the second side wall of the heat-insulating water tank. When the photovoltaic panel is in a horizontal state, the heat-insulating water tank is pushed up by the pusher to the bottom position of the gap between two adjacent rotatable photovoltaic units, so that the second side walls on the left and right sides of the heat-insulating water tank respectively snap into the snap-fit ​​grooves on the bottom surface of the photovoltaic panel of the adjacent rotatable photovoltaic unit at its top.

[0012] In the above technical solution, the height of the second sidewalls on the left and right sides of the heat-insulating water tank is higher than the height of the first sidewalls on the front and rear sides, so that the second sidewalls can be inserted into the snap-fit ​​groove.

[0013] The advantages and beneficial effects of this utility model are as follows:

[0014] (1) This utility model can be adjusted to multiple working modes for different external environments, namely, rain and snow heat preservation mode, light and ventilation mode, high wind speed power generation mode and low wind speed power generation mode, so as to achieve many functions such as heat insulation, light transmission, ventilation, rain protection and heat preservation.

[0015] (2) The heat-insulating water tank of this utility model is a rectangular tank, which is used to seal the gap between the photovoltaic panels on both sides of its top, thereby achieving the effects of sealing and heat preservation as well as collecting rain and snow falling through the gap.

[0016] (3) The present invention provides a strip-shaped snap-fit ​​groove on the bottom surface of the photovoltaic panel of the rotatable adjustable photovoltaic panel mechanism of the rotatable photovoltaic unit, which corresponds to the second side wall of the heat-insulating water tank. When the photovoltaic panel is in a horizontal state, the heat-insulating water tank is pushed up by the pusher to the bottom position of the gap between two adjacent rotatable photovoltaic units, so that the second side walls on the left and right sides of the heat-insulating water tank respectively snap into the snap-fit ​​groove on the bottom surface of the photovoltaic panel of the adjacent rotatable photovoltaic unit at the top, thereby forming an interlocking between the heat-insulating water tank and the photovoltaic panel, which is more stable.

[0026] Example 1

[0027] To enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below with reference to specific embodiments.

[0028] An intelligent BIPV photovoltaic system, participating in the attached Figure 1 -Appendix Figure 7 It includes a rotatable photovoltaic unit 10, a lifter 6, an insulated water tank 7, and a sensor module 8.

[0029] See appendix Figure 1 and attached Figure 7 Multiple rotatable photovoltaic units 10 are arranged in a rectangular array on the main steel frame structure 9 of the building roof. A pusher 6 and an insulated water tank 7 are arranged below each row of adjacent rotatable photovoltaic units 10. Specifically, the pusher 6 is vertically installed on the main steel frame structure 9, and the insulated water tank 7 is installed on the top of the pusher 6. The pusher 6 can drive the insulated water tank 7 to move up and down, adjusting the vertical position of the insulated water tank 7. The sensor module 8 is installed on the main steel frame structure 9 and is used to monitor the outdoor environment of the building, such as sunlight, wind speed, temperature, rain and snow, and upload the monitoring data to the control system through a wired / wireless communication system. The control system will control whether the pusher 6 is pushed up and control the rotation angle of the rotatable photovoltaic units 10 according to the monitoring data.

[0030] See appendix Figure 1 and attached Figure 5The rotatable photovoltaic unit 10 includes two centrally symmetrically arranged rotatable and adjustable photovoltaic panel mechanisms (see Appendix). Figure 5 Each rotatable adjustable photovoltaic panel mechanism includes a photovoltaic panel 1, a bushing 2, a rotating shaft 3, a bearing support 4, a gear 5, and a motor (not shown in the figure). The rotating shaft 3 is mounted on the main steel frame structure 9 at both ends via the bearing support 4. The motor is fixedly mounted on the main steel frame structure 9, and the motor's output shaft is connected to the gear 5 on the rotating shaft 3, thus driving the rotating shaft 3 to rotate. The bushing 2 is fixedly connected to the rotating shaft 3, and the photovoltaic panel 1 is fixedly connected to the bushing 2. In other words, the motor (not shown in the figure) drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the bushing 2 and the photovoltaic panel 1 to rotate, thereby adjusting the angle of the photovoltaic panel 1.

[0031] See appendix Figure 6 The insulated water tank 7 is a rectangular tank used to seal the gaps between the photovoltaic panels 1 on both sides of its top, thereby achieving the effects of sealing and heat preservation as well as catching rain and snow falling through the gaps. Specifically, the insulated water tank 7 includes a base plate 7.3, two first side walls 7.1, and two second side walls 7.2. The two first side walls 7.1 are fixedly connected to the front and rear sides of the base plate 7.3, and the two second side walls 7.2 are fixedly connected to the left and right sides of the base plate 7.3.

[0032] Furthermore, the bottom surface of the photovoltaic panel 1 of the rotatable adjustable photovoltaic panel mechanism of the rotatable photovoltaic unit 10 is provided with a strip-shaped locking groove 1.1 corresponding to the second side wall 7.2 of the heat-insulating water tank 7. When the photovoltaic panel 1 is in a horizontal state, the heat-insulating water tank 7 is pushed up by the pusher 6 to the bottom position of the gap between two adjacent rotatable photovoltaic units 10, so that the second side walls 7.2 on the left and right sides of the heat-insulating water tank 7 respectively lock into the locking groove 1.1 on the bottom surface of the photovoltaic panel 1 of the adjacent rotatable photovoltaic unit 10 at the top (that is, the second side wall 7.2 on the left side of the heat-insulating water tank 7 locks into the locking groove 1.1 on the bottom surface of the photovoltaic panel 1 on the right side of the rotatable photovoltaic unit 10, and the second side wall 7.2 on the right side of the heat-insulating water tank 7 locks into the locking groove 1.1 on the bottom surface of the photovoltaic panel 1 on the left side of another adjacent rotatable photovoltaic unit 10), thereby forming an interlocking relationship between the heat-insulating water tank 7 and the photovoltaic panel 1, which is more stable. It should be noted that the height of the second sidewalls 7.2 on the left and right sides of the insulated water tank 7 is higher than the height of the first sidewalls 7.1 on the front and rear sides, so that the second sidewalls 7.2 can be inserted into the snap-fit ​​groove 1.1.

[0033] Example 2

[0034] The working method of the intelligent BIPV photovoltaic system:

[0035] (1) When sensor module 8 detects that the external environment is in a rainy or snowy state and the temperature is low, that is, when the temperature of the external environment is lower than the system set value, the intelligent BIPV photovoltaic system adjusts to the rain and snow insulation mode (see Appendix). Figure 1 ):

[0036] Adjust all the photovoltaic panels 1 of the rotatable photovoltaic units 10 to a horizontal position, and push the heat-insulating water tank 7 to the bottom of the gap between two adjacent rotatable photovoltaic units 10, so that the heat-insulating water tank 7 seals the gap between the photovoltaic panels 1 on both sides of its top, thereby achieving the effect of sealing and heat preservation and catching rain and snow falling through the gap; and make the second sidewalls 7.2 on the left and right sides of the heat-insulating water tank 7 respectively snap into the snap-fit ​​grooves 1.1 on the bottom surface of the photovoltaic panel 1 of the adjacent rotatable photovoltaic unit 10 at its top, so that the heat-insulating water tank 7 and the photovoltaic panel 1 form an interlocking structure, which is more stable.

[0037] (2) When sensor module 8 detects that the ambient light intensity is low, i.e., when the ambient light intensity is lower than the system set value, the intelligent BIPV photovoltaic system adjusts to the lighting and ventilation mode (see Appendix). Figure 2 ):

[0038] The pusher 6 retracts until the height of the insulated water tank 7 does not interfere with the angle adjustment of the photovoltaic panel 1. Under the adjustment of the motor (not shown in the figure), the photovoltaic panel 1 of the rotatable photovoltaic unit 10 is tilted at a fixed angle (≤20°) with the main steel frame structure 9, and the photovoltaic panels 1 of the same rotatable photovoltaic unit 10 are located in a straight line, thereby achieving the effects of ventilation, improving light transmission, reducing indoor lighting load, and saving energy.

[0039] (3) When sensor module 8 detects that the ambient light intensity and wind speed are good, that is, when the ambient light intensity and wind speed are higher than the system set value, the intelligent BIPV photovoltaic system adjusts to the high wind speed power generation mode (see Appendix). Figure 3 ):

[0040] The pusher 6 retracts until the height of the insulated water tank 7 does not interfere with the angle adjustment of the photovoltaic panel 1. The photovoltaic panel 1 of the rotatable adjustable photovoltaic panel mechanism of the same rotatable photovoltaic unit 10 is set in a Λ shape under the adjustment of the motor (not shown in the figure), thereby increasing the light-receiving area of ​​the photovoltaic panel 1, reducing wind pressure and improving airflow.

[0041] (4) When sensor module 8 detects that the ambient light intensity is good and the wind speed is low, that is, when the ambient light intensity is higher than the system set value and the ambient wind speed is lower than the system set value, the intelligent BIPV photovoltaic system adjusts to the low wind speed power generation mode (see Appendix). Figure 4 ):

[0042] The pusher 6 retracts until the height of the insulated water tank 7 does not interfere with the angle adjustment of the photovoltaic panel 1. The photovoltaic panel 1 of the rotatable adjustable photovoltaic panel mechanism of the same rotatable photovoltaic unit 10 is set in a V-shape under the adjustment of the motor (not shown in the figure). This increases the light-receiving area and the reflected irradiance between the photovoltaic panels 1, thereby increasing the power generation.

[0043] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” are used in the embodiments to describe the relationship of one element or feature shown in the figures relative to another element or feature. It should be understood that, in addition to the orientations shown in the figures, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figures is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations. The device may be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0044] Moreover, relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0045] The present invention has been described above by way of example. It should be noted that, without departing from the core of the present invention, any simple modifications, alterations or other equivalent substitutions that can be made by those skilled in the art without creative effort fall within the protection scope of the present invention.
