For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to the specific circumstances.

[0031] like Figures 1 to 5 As shown, the mine wind window capable of rotating as a whole provided by the embodiment of the utility model comprises a window frame 2, a window body 1, a side baffle 4, a reduction motor 5, a transmission mechanism and a hand crank 6.

[0032] The window body 1 is rotatably installed in the window frame 2. The window body 1 is a shutter-type window. The rotating shaft 3 at the upper part of the window body 1 is located at the center of the top, and the rotating shaft 3 at the lower part of the window body 1 is located at the center of the bottom. The upper rotating shaft 3 and the lower rotating shaft 3 are both provided with limit plates that match the window frame 2. Side baffles 4 are provided on both sides of the window body 1. The side baffles 4 match the left wall plate or the right wall plate of the window frame 2. The side baffles 4 on both sides are respectively located at the front and rear sides of the window frame 2.

[0033] A reduction motor 5 and a transmission mechanism are arranged in the window frame 2, and the output shaft of the reduction motor 5 is connected to the rotating shaft 3 at the upper part of the window body 1 through the transmission mechanism. The driving gear 9 of the transmission mechanism is connected to the rotating shaft 3 of the hand crank 6, and the hand crank 6 is arranged outside the window frame 2.

[0034] It should be noted that during daily ventilation of the mine, ventilation is carried out through multiple blades of the window 1, and the air volume is adjusted. When encountering special circumstances and further increasing the ventilation volume, the staff rotates the window 1 ninety degrees as a whole to achieve the ventilation demand of large flow, and personnel and materials can also be evacuated quickly in this state. The limit plate can not continue to rotate when the window 1 rotates ninety degrees, thereby maintaining the current state. The side baffles 4 on both sides can play a limiting role after the window 1 is reset, and at the same time play a role in further sealing the window frame 2 and the window 1. When the window 1 needs to be rotated ninety degrees as a whole, the reduction motor 5 is started, and the reduction motor 5 drives the window 1 to rotate ninety degrees through the transmission mechanism. The staff can also manually drive the driving gear 9 of the transmission mechanism to rotate through the hand crank 6, thereby realizing the rotation of the window 1. The wind window can quickly adjust its angle, thereby increasing the evacuation channel for personnel and materials, allowing personnel and materials to evacuate quickly, and avoiding delays in the best evacuation time. Therefore, the wind window has a simple structure and strong practicality.

[0035] In this embodiment, the transmission mechanism includes a driving bevel gear 7 , a driven bevel gear 8 , a driving gear 9 , a rack 10 and a driven gear 11 .

[0036] The output shaft of the reduction motor 5 is coaxially arranged with the rotating shaft 3 of the window body 1. The output shaft of the reduction motor 5 is installed with a driving bevel gear 7. The driving bevel gear 7 is meshed with a driven bevel gear 8. The driven bevel gear 8 is rotatably installed in the window frame 2. The driven bevel gear 8 and the driving gear 9 are coaxially fixed.

[0037] The rack 10 is slidably installed in the window frame 2. The rack 10 is located on one side of the rotating shaft 3 of the window body 1. The driving gear 9 is located above the rack 10. The teeth of the driving gear 9 and the top wall of the rack 10 are meshed.

[0038] A driven gear 11 is mounted on the rotating shaft 3 at the upper portion of the window body 1 , and the driven gear 11 is meshed with teeth on the side wall of the rack 10 .

[0039] It should be noted that when the transmission mechanism is working, the reduction motor 5 drives the active bevel gear 7 to rotate, the active bevel gear 7 drives the driven bevel gear 8 to rotate, the driven bevel gear 8 and the driving gear 9 rotate together, the driving gear 9 drives the rack 10 to move, the rack 10 drives the driven gear 11 to rotate, and the driven gear 11 rotates the window 1 as a whole through the rotating shaft 3.

[0040] In this embodiment, a locking mechanism is also included. The locking mechanism includes a locking pin 12 , a return spring 13 , a swing rod 16 , a driven rod 17 , an active rod 18 , a first magnet 19 and a second magnet 20 .

[0041] The lock pin 12 is slidably installed in the window frame 2. The lock pin 12 is horizontally arranged. A return spring 13 is arranged at the rear end of the lock pin 12. A slope 14 matching with the window body 1 is arranged at the front end of the lock pin 12. A pin hole 15 is arranged in the window body 1.

[0042] The middle part of the swing rod 16 is hinged in the window frame 2, the telescopic end of the lower end of the swing rod 16 is hinged to the top of the lock pin 12, the telescopic end of the upper end of the swing rod 16 is hinged to the right end of the driven rod 17, the driven rod 17 is slidably installed in the window frame 2, the left end of the active rod 18 is connected to the right end of the rack 10, and the left end of the driven rod 17 and the right end of the active rod 18 are respectively provided with a matching first magnet 19 and a second magnet 20.

[0043] The side wall on the left side of the rack 10 is a polished rod section 101 , and the side wall on the right side of the rack 10 is provided with teeth matched with the driven gear 11 .

[0044] When the front end of the locking pin 12 is located in the pin hole 15 of the window body 1 , the polished rod section 101 of the rack 10 is located at the driven gear 11 .

[0045] It should be noted that when the window 1 is in the initial state, the front end of the locking pin 12 is located in the pin hole 15 of the window 1, and the bare rod section 101 of the rack 10 is located at the driven gear 11. The reduction motor 5 is started, and the reduction motor 5 drives the rack 10 to move through the active bevel gear 7, the driven bevel gear 8 and the driving gear 9. The rack 10 drives the driven rod 17 to move through the active rod 18. At this time, the first magnet 19 and the second magnet 20 are attracted, and then the locking pin 12 is driven to move through the swing rod 16. When the front end of the locking pin 12 moves out of the pin hole 15 of the window 1, the teeth on the right side of the driven gear 11 and the rack 10 are meshed, so that the rack 10 drives the driven gear 11 to rotate, and the driven gear 11 rotates the window 1 as a whole to ninety degrees through the rotating shaft 3. During the rotation of the window 1, the first magnet 19 and the second magnet 20 are separated, and the locking pin 12 is reset.

[0046] When the window 1 needs to be restored to its original state, the reduction motor 5 is started, and the reduction motor 5 causes the rack 10 to move in the opposite direction, and the window 1 rotates as a whole. After the window 1 and the front end inclined surface 14 of the locking pin 12 abut against each other, the locking pin 12 retreats until the window 1 is reset, and then the front end of the locking pin 12 returns to the pin hole 15 of the window 1 under the action of the reset spring 13.

[0047] The locking mechanism of this embodiment can unlock the window 1 before the window 1 is rotated as a whole, or lock the window 1 after the window 1 is rotated as a whole, thereby achieving the purpose of automatic unlocking and locking, thereby optimizing the control method and improving the window opening efficiency.

[0048] In this embodiment, there are two groups of transmission mechanisms, and the two groups of transmission mechanisms are symmetrically arranged about the rotating shaft 3 of the window 1 .

[0049] There are two sets of locking mechanisms, which are respectively arranged on the left and right sides of the window frame 2 .

[0050] The two sets of transmission mechanisms and the two sets of locking mechanisms correspond one to one.

[0051] It should be noted that there are two sets of locking mechanisms, so as to improve the effect of locking the window 1 .

[0052] In this embodiment, sealing strips 21 matching with the window frame 2 are provided on the top and bottom of the window body 1 .

[0053] It should be noted that the sealing strip 21 can improve the sealing between the window body 1 and the window frame 2 .

[0054] In this embodiment, it is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiment, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiment should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and therefore it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
