Compared with the photovoltaic panel used in the prior art, which needs to be exposed to the external environment for a long time, the photovoltaic panel assembly 10 in the power generation device can change the state of the photovoltaic panel assembly 10 according to the use requirements and the influence of environmental factors, namely: when the day weather is better, the photovoltaic panel group 10 is unfolded so as to fully absorb solar energy; when sunlight is weak at night or on a cloudy day, the photovoltaic panel group 10 is wound and stored in the storage cavity by the winding mechanism 30. That is to say, the photovoltaic panel group 10 in the power generation device can meet the requirements of solar power generation, and at the same time, the two states of unfolding and winding are selected according to environmental factors, so that the photovoltaic panel group 10 is not required to be exposed to the external environment all the time in the whole service cycle, and further, the damage to the photovoltaic panel group 10 is effectively reduced, the protection performance to the photovoltaic panel group 10 is improved, and the service life of the photovoltaic panel group 10 is prolonged.

By means of the arrangement, the utilization rate of solar energy can be effectively improved, and the power generation efficiency of the power generation device is further improved. Meanwhile, the flexible member 102 is arranged to facilitate winding of any two adjacent photovoltaic panels 101, that is, when the photovoltaic panel group 10 is wound by the winding mechanism 30, the arrangement position of the flexible member 102 is taken as a bending point, so that not only is winding operation between the plurality of photovoltaic panels 101 realized, but also the hidden danger of bending damage of the photovoltaic panels 101 caused by winding is reduced.

Referring to fig. 2, fig. 2 shows a partial cross-sectional view of a power generation device in an embodiment of the present invention. In some embodiments, the winding mechanism 30 includes a rotating shaft 31 and a winding plate 32; the winding plate 32 extends into the storage cavity, and the connecting end of the photovoltaic panel group 10 is connected with the winding plate 32; the rotating shaft 31 is rotatably connected to the storage box 20, the winding plate 32 is connected to the rotating shaft 31, and the winding plate 32 can rotate synchronously with the rotating shaft 31.

In this embodiment, the containing box 20 has four side walls and a top surface, that is, the bottom surface of the containing box 20 is open, the four side walls and the top surface enclose a storage cavity, the open and storage cavity are communicated, so that the free end 11 of the photovoltaic panel group 10 extends out of and into the open. The quantity of pivot 31 is two, and two pivot 31 are relative and the interval arrangement in the both sides along winding plate 32 length direction, and every pivot 31 all with winding plate 32 rigid coupling, and every pivot 31 is kept away from winding plate 32's one end and is passed through the bearing respectively and be connected with the lateral wall rotation of containing box 20 last corresponding side. The length direction of the photovoltaic panel 101 is the same as the length direction of the winding plate 32, the width direction of the photovoltaic panel 101 is the same as the width direction of the photovoltaic panel 101, and the connecting end of the photovoltaic panel group 10 is hinged to the winding plate 32.

In practical use, the winding mechanism 30 further includes a motor and a speed reducing mechanism, a motor shaft of the motor is in transmission connection with a power input end of the speed reducing mechanism, a power output end of the speed reducing mechanism is in transmission connection with one of the rotating shafts 31, the rotating shafts 31 are driven by the motor to rotate around the circumferential direction of the rotating shafts 31, and then the winding plate 32 is driven to rotate synchronously, so that the winding operation of the photovoltaic panel group 10 is realized. The motor can rotate forward and backward, for example, when the motor is in forward transmission, the winding operation of the photovoltaic panel group 10 is realized, and when the motor is in reverse rotation, the unwinding operation of the photovoltaic panel group 10 is realized.

Of course, the rotation of the rotating shafts 31 may also be achieved manually, for example, a handle is fixedly disposed at one end of one of the rotating shafts 31 far away from the storage box 20, and the worker rotates the handle to further drive the rotating shaft 31 to rotate, so as to achieve the winding operation of the photovoltaic panel group 10 through the synchronous rotation of the winding plates 32. For example, when the handle is rotated clockwise, the winding operation of the photovoltaic panel group 10 is realized, and when the handle is rotated counterclockwise, the unwinding operation of the photovoltaic panel group 10 is realized. Alternatively, when it is desired to unfold the photovoltaic panel assembly 10, the free end 11 of the photovoltaic panel assembly 10 may be manually dragged. In any of these embodiments, the photovoltaic panel group 10 may be wound, stored, or unwound.

The photovoltaic panel group 10 is wound by clockwise rotation of the rotating shaft 31, and the photovoltaic panel group 10 is unfolded by counterclockwise rotation of the rotating shaft 31. When the photovoltaic panel group 10 needs to be unfolded, the counterclockwise rotation of the rotating shaft 31 causes the return member 33 to generate elastic deformation, so as to generate elastic potential energy. When the photovoltaic panel group 10 needs to be wound and stored, the rotating shaft 31 needs to rotate clockwise, the acting force for driving the rotating shaft 31 to rotate counterclockwise gradually decreases or even disappears, at this time, the elastic potential energy generated by the return member 33 can be converted into the power potential energy for pushing the rotating shaft 31 to rotate clockwise, and then the rotating shaft 31 is driven to rotate clockwise by the return member 33, so as to return to the initial state, and the winding operation of the photovoltaic panel group 10 is realized.

The arrangement of the adjusting mechanism can enable the rotating shaft 31 to move in the left-right direction, and the rotating shaft 31 drives the winding plate 32 to move synchronously, so that the inclination angle of the photovoltaic panel group 10 is adjusted, and the photovoltaic panel group 10 can be more suitable for the irradiation direction of sunlight to fully absorb solar energy. In actual use, the photovoltaic panel group 10 is in an unfolded state, and the free end 11 of the photovoltaic panel group 10 is hinged on the installation table 621. At this time, if the inclination angle of the photovoltaic panel assembly 10 needs to be adjusted to be small, the adjusting mechanism can drive the rotating shaft 31 to move rightwards, and then the photovoltaic panel assembly 10 is driven to swing clockwise around the hinged position with the mounting table 621 through the movement of the rotating shaft 31. If the inclination angle of the photovoltaic panel group 10 needs to be increased, the rotating shaft 31 is driven to move leftwards through the adjusting mechanism.

Wherein, if the length of the photovoltaic panel group 10 after being unfolded can be changed along with the change of the inclination angle of the photovoltaic panel group 10, that is: if the inclination angle of the photovoltaic panel group 10 becomes gentle, the length of the photovoltaic panel group 10 to be unfolded is increased; if the inclination angle of the photovoltaic panel group 10 becomes steep, the length of the photovoltaic panel group 10 spread out decreases.

Of course, the length of the photovoltaic panel assembly 10 after being unfolded may not vary with the inclination angle of the photovoltaic panel assembly 10, that is, the length of the photovoltaic panel assembly 10 after being unfolded is constant, and the change of the inclination angle of the photovoltaic panel assembly 10 can change the vertical height of the storage box 20 from the installation platform 621. Namely: if the inclination angle of the photovoltaic panel group 10 becomes gentle, the vertical height between the storage box 20 and the installation platform 621 becomes smaller; if the inclination angle of the photovoltaic panel group 10 becomes steep, the vertical height between the storage box 20 and the installation floor 621 becomes large.
