In order to prevent the free end of the blade 2 from bending due to the influence of gravity, the blade 2 is preferably made of a metal sheet or a non-metal material with high strength, such as hard plastic; it is also possible to provide the notches 22 with a view to reducing the weight of the blade 2, while ensuring the tightness.

In order to realize that the plurality of blades 2 can be accommodated in the cover plate 1 when not rotating, the cover plate 1 is provided with a split structure, as shown in fig. 4, the cover plate 1 comprises a first sub cover plate 11 and a second sub cover plate 12, the first sub cover plate 11 and the second sub cover plate 12 can be mutually clamped to form an accommodating space with an accommodating groove at the inner side, the driving assembly 3 and the plurality of blades 2 are arranged in the accommodating space, and the blades 2 can be screwed in or out from the accommodating groove.

Further, fig. 8 is a partial enlarged view of a in fig. 5, the driving assembly 3 includes a driving shaft 31 and a transmission belt 32, the rotation of the driving shaft 31 can be driven by a single motor, the driving shaft 31 can drive the transmission belt 32 to rotate, and the transmission belt 32 can drive a plurality of blades 2 to rotate simultaneously, so that adjacent two blades 2 can be partially overlapped to close the cover plate opening. The driving assembly 3 is used for driving all the blades 2 to rotate simultaneously, and the specific structure thereof may be various, for example, the driving shaft 111 may be set to rotate, the blades 2 are fixed to the rotating shaft 111 through the connecting holes 21, and rotate simultaneously with the rotating shaft 111, and at this time, the blades 2 may be driven to rotate only by driving the rotating shaft 111 to rotate; the rotating shaft 111 can be fixed relative to the cover plate, the blade 2 is sleeved on the rotating shaft 111 through the connecting hole 21 and can rotate relative to the rotating shaft 111, the end part of the blade 2 is driven to rotate at the moment, and the blade 2 can swing by taking the rotating shaft 111 as a shaft to realize free end swing. The driving belt 32 may be a belt, a rope, a wire, or the like.

Specifically, fig. 8 is a schematic structural diagram of the driving assembly 3, in fig. 8, the transmission belt 32 is a belt, each rotating shaft 111 is fixedly connected with the transmission belt 32, and the blade 2 is fixed with the rotating shaft 111 through the connecting hole 21 and rotates simultaneously with the rotating shaft 111. When the driving shaft 31 rotates in fig. 8, the driving shaft 31 can drive the driving belt 32 to rotate, the driving belt 32 drives the fixedly connected rotating shaft 111 to rotate, the rotating shaft 111 drives the blades 2 to rotate, and then all the blades 2 can be driven to rotate simultaneously only by one power source, namely, the driving shaft 31.

Further, the connection mode of the transmission belt and the rotating shaft in fig. 8 can be replaced by that the transmission belt 32 is wound on each rotating shaft 111, when the driving shaft 31 rotates, the driving shaft 31 can drive the transmission belt 32 to rotate, because the transmission belt 32 and the wound rotating shaft 111 have friction force, the friction force can drive the rotating shaft 111 to rotate, the rotating shaft 111 drives the blades 2 to rotate, and then all the blades 2 can be driven to rotate simultaneously only by one power source, namely, the driving of the driving shaft 31.

Further, fig. 9 is a schematic view of another structure of the driving assembly in fig. 8, in fig. 9, the transmission belt 32 is a belt, an end portion of each blade 2 provided with the connection hole 21 is fixedly connected with the transmission belt 32, the rotating shaft 111 is stationary with respect to the cover plate 1, and the blade 2 is sleeved on the rotating shaft 111 through the connection hole 21 and can rotate with respect to the rotating shaft 111. In fig. 9, when the driving shaft 31 rotates, the driving shaft 31 can drive the driving belt 32 to rotate, the driving belt 32 drives the end of the fixedly connected blade 2 to rotate, and the blade rotates relative to the rotating shaft 111, so that all the blades 2 can be driven to rotate simultaneously only by one power source, i.e., the driving shaft 31.

fig. 10 is a schematic view of still another structure of the driving assembly in fig. 8, in fig. 10, the transmission belt 32 is a belt, first transmission teeth 321 are arranged on the inner side of the transmission belt 32, preferably, the first transmission teeth 321 are arranged in a plurality of segments at intervals shown in fig. 10, a second transmission tooth 23 is correspondingly arranged on the end portion of each blade 2 provided with the connecting hole 21 in the circumferential direction, and the first transmission teeth 321 are meshed with the second transmission teeth 23. In fig. 10, when the driving shaft 31 rotates, the driving shaft 31 can drive the driving belt 32 to rotate, and the first driving teeth 321 on the driving belt 32 are engaged with the second driving teeth 23 of the blades 2, so that the blades can rotate relative to the rotating shaft 111, and further, the driving of only one power source, i.e., the driving shaft 31, can drive all the blades 2 to rotate simultaneously. In fig. 10, the first transmission teeth 321 are provided at intervals in multiple stages inside the transmission belt 32, which can save cost, and the first transmission teeth 321 may be provided on the entire inside of the transmission belt 32; and the second transmission gear 23 is only arranged in the circumferential direction of the end part of the blade 2 provided with the connecting hole 21, because the rotation angle of the blade 2 is not large, the transmission of power can be realized only by arranging a section of second transmission gear 23 structure.

It is anticipated that the present solution is not limited to the structure of the driving unit 3, but is preferable to protect the structure of the driving unit 3 and the transmission of the power with the blade 2. Whilst it is envisaged that the transmission of power between the drive shaft 31 and the drive belt 32 is effected by friction between the drive belt 32 and the drive shaft 31, the drive shaft 31 acting like a pulley, with reference to the arrangement of figure 10, it is also possible to provide drive teeth on the drive shaft 31 such that the transmission of power between the drive shaft 31 and the drive belt 32 is effected by meshing.

in order to prevent the rotation angle of the blade 2 from being too large or too small, a limit shaft 33 and a stopper 34 are further provided. In fig. 8 to 10, two limiting shafts 33 are provided, and are symmetrically arranged on two sides of the driving shaft 31, the stopping portions 34 are arranged on the driving shaft 31, and the limiting shafts 33 and the stopping portions 34 cooperate to define the rotation angle of the driving shaft 31. When the driving shaft 31 rotates, the stopping portion 34 is driven to rotate, and the stopping portion 34 can abut against the limiting shaft 33 to limit the rotation angle of the driving shaft 31. For example, when the driving shaft 31 rotates clockwise, all the blades 2 are driven to rotate simultaneously, and when the stop portion 34 on the driving shaft 31 abuts against one of the limiting shafts 33 located at the lower side in fig. 8, the driving shaft 31 cannot rotate any more at this time, and all the blades 2 are screwed into the cover plate 1 at this time. Therefore, the axes of the two limiting shafts 33 are connected with the axis of the driving shaft 31 to form an included angle, which is the angle range that the driving shaft 31 can rotate; the two limit shafts 33 correspond to two limit positions of the blade 2 which is completely screwed into the cover plate 1 and completely screwed out of the cover plate 1 respectively. The arrangement mode is simpler in structure and good in limiting effect.

in conclusion, drive assembly 3 has adopted a power supply drive shaft 31, and transmit power through drive belt 32, drive all blades 2 and rotate simultaneously, and drive shaft 31 is rotatory according to the first direction, a plurality of blades 2 are rotatory simultaneously along the first direction, drive shaft 31 is rotatory according to the second direction, a plurality of blades 2 are rotatory simultaneously along the second direction, the setting of this kind of structure makes blade pivoted direction be convenient for control more, the synchronism is better, the part overlap joint between two blades 2 is realized more easily, and can not take place to interfere, response speed is also faster.
