Specifically, underground ventilation equipment, especially in wind ducts, cannot be used or has a low service life and requires frequent maintenance. However, when it comes to specific application environments such as duct air distribution and return air dust control, the air volume adjustment of different ducts can achieve positive application effects. For this situation, there is currently a lack of corresponding solutions or related equipment. Utility Model Content

[0004] The device comprises a wind tube, wherein a power main shaft is passed through the wind tube, and the power main shaft is passed through the housing of the air outlet;

[0005] Preferably, one end of the power main shaft is rotatably arranged on the inner wall of the wind tube, and the other end passes through the wind tube as a connection end of the power equipment.

[0006] The power main shaft is provided with two driving gears, which are arranged mirror-symmetrically with respect to the center of the air outlet; air volume regulating blades are respectively fixedly arranged on the power main shaft on the outside of the two driving gears;

[0007] A driven shaft is also provided in the air outlet housing, and a driven gear meshing with the driving gear is provided on the driven shaft;

[0008] Air volume regulating blades are respectively arranged on the driven shaft and outside the driven gear.

[0009] The beneficial effects of the utility model are as follows: the utility model solves the problem that the existing wind window has low strength and cannot be used in strong wind environment, especially the synchronous rotation and opening of the six-sided fan blades can make the device easy to open and close, and flexibly adjust the air volume. Moreover, the device can cooperate with the rotating mechanical power to realize flexible opening and closing, and has higher strength, low maintenance frequency, long service life, and great market promotion value.

[0015] The realization of the purpose, functional features and advantages of the utility model will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0016] Reference Figure 1 , Figure 2 and Figure 3 The utility model discloses a six-pointed wind window, comprising a wind tube 1, wherein a power main shaft 4 is provided in the wind tube 1, and the power main shaft 4 is provided on the housing of the air outlet;

[0017] Preferably, one end of the power main shaft 4 is rotatably arranged on the inner wall of the wind tube 1, and the other end passes through the wind tube 1 as a connection end of the power equipment.

[0018] The power main shaft 4 is provided with two driving gears, which are arranged mirror-symmetrically with respect to the center of the air outlet; air volume regulating blades 3 are respectively fixedly arranged on the power main shaft 4 on the outside of the two driving gears;

[0019] A driven shaft 5 is also provided in the air outlet housing, and a driven gear meshing with the driving gear is provided on the driven shaft 5;

[0020] Air volume regulating blades 3 are respectively arranged on the driven shaft 5 outside the driven gear.

[0021] The effect achieved in this way is that, through the action of the rotating power device, the action of the power main shaft 4 drives the air volume regulating blade 3 to flip, and due to the meshing relationship between the driving gear and the driven gear, the air volume regulating blade 3 on the driven shaft 5 flips synchronously, thereby realizing the adjustment of the air duct area at the air outlet position.

[0022] Furthermore, the driven shaft 5 includes four short shafts, and two short shafts form a group of the four short shafts, and each group of short shafts is arranged opposite to each other;

[0023] The short shaft is rotatably arranged on the inner cavity wall of the air outlet;

[0024] The air volume regulating blades 3 are six in total, and the air volume regulating blades 3 are arranged in a close-fitting manner in a flat state.

[0025] That is to say, the movement of the power main shaft 4 drives the movement of the six-sided air volume regulating blades 3 to adjust the flux of the air outlet position. When the air volume regulating blades 3 are flat, only the matching gap of the middle gear is ventilated, and the ventilation air volume can be adjusted by controlling and adjusting its opening.

[0026] Furthermore, a positioning frame 2 is provided in the middle of the wind tube 1. The positioning frame 2 is a hexagonal frame structure, and the power main shaft 4 is set through the positioning frame 2; one end of the short shaft is rotatably set on the inner cavity wall of the air outlet, and the other end is passed through the positioning frame 2.

[0027] Preferably, the driving gear and the driven gear are both arranged in the positioning frame 2 .

[0028] The effect achieved thereby is to improve the stability of equipment assembly and use.

[0029] Furthermore, the driving gear and the driven gear are both bevel gears.

[0030] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
