Specifically, the pusher 6 is vertically installed on the main steel frame structure 9, and the insulation water tank 7 is installed on the top of the pusher 6. The pusher 6 can drive the warm water tank 7 to move up and down to adjust the upper and lower positions of the warm water tank 7; the sensor module 8 is arranged on the main steel frame structure 9, and is used to monitor the light, wind speed, temperature, rain and snow and other conditions of the outdoor environment of the building, 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 unit 10 according to the monitoring data.

[0039] See attached Figure 1 and attached Figure 5 The rotatable photovoltaic unit 10 includes two rotatable and adjustable photovoltaic panel mechanisms arranged in a central symmetric manner (see attached Figure 5), each rotatable and adjustable photovoltaic panel mechanism includes a photovoltaic panel 1, a sleeve 2, a rotating shaft 3, a bearing support 4, a gear 5 and a motor (not shown in the figure); wherein, both ends of the rotating shaft 3 are mounted on the main steel frame structure 9 through the bearing support 4, and the motor is fixedly mounted on the main steel frame structure 9, and the output shaft of the motor is transmission-connected with the gear 5 on the rotating shaft 3, so that the rotating shaft 3 can be driven to rotate by the motor; the sleeve 2 is fixedly connected to the rotating shaft 3, and the photovoltaic panel 1 is fixedly connected to the sleeve 2, that is, the motor (not shown in the figure) drives the rotating shaft 3 to rotate, and the rotating shaft 3 drives the sleeve 2 and the photovoltaic panel 1 to rotate, so that the angle of the photovoltaic panel 1 can be adjusted.

[0040] See attached Figure 6 The heat preservation water tank 7 is a rectangular tank body, which is used to block the gaps between the photovoltaic panels 1 on both sides of the top thereof, so as to achieve the effects of sealing and heat preservation and collecting rain and snow falling through the gaps. Specifically, the heat preservation water tank 7 includes a bottom 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 bottom plate 7.3, and the two second side walls 7.2 are fixedly connected to the left and right sides of the bottom plate 7.3.

It should be noted that the height of the second side walls 7.2 on the left and right sides of the heat preservation water tank 7 is higher than the height of the first side walls 7.1 on the front and rear sides, so that the second side walls 7.2 can be inserted into the clamping groove 1.1.

[0042] Embodiment 2

[0043] The regulation method of the multi-mode photovoltaic system for the roof of a building:

[0044] (1) When the sensor module 8 detects that the external environment is in a state of rain and snow and the temperature is low, that is, when the temperature of the external environment is lower than the system setting value, the multi-mode photovoltaic system for the roof of the building is adjusted to the rain and snow insulation mode (see Appendix Figure 1 ):

[0045] The photovoltaic panels 1 of all the rotatable photovoltaic units 10 are adjusted to a horizontal state, and the thermal insulation water tank 7 is pushed up to the bottom position of the gap between two adjacent rotatable photovoltaic units 10, so that the thermal insulation water tank 7 blocks the gap between the photovoltaic panels 1 on both sides of its top, thereby achieving the effect of sealing and heat preservation as well as receiving rain and snow falling through the gap; and the second side walls 7.2 on the left and right sides of the thermal insulation water tank 7 are respectively inserted into the snap-in grooves 1.1 on the bottom surfaces of the photovoltaic panels 1 of the rotatable photovoltaic units 10 adjacent to its top, so that the thermal insulation water tank 7 and the photovoltaic panels 1 form an interlocking structure, which is more stable.

[0046] (2) When the sensor module 8 detects that the light intensity of the external environment is low, that is, when the light intensity of the external environment is lower than the system setting value, the multi-mode photovoltaic system used on the roof of the building is adjusted to the lighting and ventilation mode (see Appendix Figure 2 ):

[0047] The pusher 6 retracts until the height of the insulation 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 each rotatable photovoltaic unit 10 is tilted at a fixed angle (≤20°) to the main steel frame structure 9 under the adjustment of a motor (not shown in the figure), 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 daylighting, reducing indoor lighting load, and saving energy and reducing consumption.

[0048] (3) When the sensor module 8 detects that the light intensity of the external environment is good and the wind speed is high (that is, the light intensity and wind speed of the external environment are higher than the system setting value), the multi-mode photovoltaic system used on the roof of the building is adjusted to the high wind speed power generation mode (see Appendix Figure 3 ):

[0049] The pusher 6 retracts until the height of the insulation 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 a motor (not shown in the figure), thereby increasing the light receiving area of ​​the photovoltaic panel 1, reducing wind pressure and improving diversion.

[0050] (4) When the sensor module 8 detects that the light intensity of the external environment is good and the wind speed is low (i.e., the light intensity of the external environment is higher than the system setting value and the wind speed of the external environment is lower than the system setting value), the multi-mode photovoltaic system used on the roof of the building is adjusted to the low wind speed power generation mode (see Appendix Figure 4 ):

[0051] The pusher 6 retracts until the height of the insulation 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 a motor (not shown in the figure). This increases the light-receiving area while increasing the reflected radiation between the photovoltaic panels 1, thereby increasing the power generation.

[0052] For ease of explanation, spatial relative terms such as "upper", "lower", "left", "right" and the like are used in the embodiments to illustrate the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, the spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, the element described as being "under" other elements or features will be positioned "on" other elements or features. Therefore, the exemplary term "under" can include both upper and lower orientations. The device can be positioned in other ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used here can be interpreted accordingly.

[0053] Furthermore, relational terms such as “first” and “second” and the like are merely used to distinguish one component from another having the same name, but do not necessarily require or imply any such actual relationship or order between these components.

[0054] The present invention is described above by way of example. It should be noted that, without departing from the core of the present invention, any simple deformation, modification or other equivalent replacement that can be made by those skilled in the art without inventive effort falls within the protection scope of the present invention.
