For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0026] As shown in Figure 1 and Figure 2 A new air door structure for coal mine ventilation, comprising a door frame plate 1, a door hole 2 is arranged at a position deviating from the center of the plate surface of the door frame plate 1, sliding door structures 3 are arranged at the front and rear ends of the door frame plate, the sliding door structures 3 cooperate with the door hole 2, and one of the sliding door structures 3 is provided with a ventilation fan 4.

[0027] The above technical scheme provides three working modes:

[0028] Firstly, the door hole 2 is closed by the sliding door structure 3, and ventilation is closed at this time.

[0029] Secondly, the sliding door structures 3 on both sides are simultaneously slid to be opened, and the door hole 2 realizes natural ventilation at this time.

[0030] Thirdly, the sliding door structure 3 of the side without the ventilation fan 4 is opened, at this time, the ventilation fan 4 corresponds to the door hole 2, and the ventilation fan 4 actively ventilates.

[0031] The above technical scheme can realize natural ventilation and artificial ventilation, and can be closed when ventilation is not needed, which is simple and convenient to operate.

[0032] Referring to Figure 1As shown in the drawings, the door frame 21 is installed inside the door opening 2, and the two ends of the door frame 21 protrude to the outside of the door opening 2. The door frame 21 is provided with a rib plate 22 between the door frame plate 1, and the sliding door structure 3 cooperates with the door frame 21.

[0033] The door frame 21 is provided to better fit the sliding door structure 3 and achieve the required sealing.

[0034] As shown in the drawings, Figure 1 and Figure 3 As shown in the drawings, the sliding door structure 3 includes a hood 31 and a sliding door 32. The hood 31 is installed on the plate surface of the door frame plate 1 and is located above the door opening 2. The bottom of the hood 31 is provided with a sliding groove 33. Two hanging rails 34 are provided in parallel inside the hood 31. A screw rod 35 is rotatably provided inside the hood 31. The screw rod 35 cooperates with the bearing (not shown) between the hood 31. A speed reducer motor 36 is installed on the door frame plate 1 to drive the rotation of the screw rod 35. The sliding door 32 cooperates with the sliding groove 33 and is closed at the door frame 21 after transversely sliding along the sliding groove 33. The upper end of the sliding door 32 is provided with a lifting bracket 37. The lifting bracket 37 has a pipe portion 38 passing through the hanging rail 34. The lifting bracket 37 has a threaded sleeve 39 cooperating with the screw rod 35. The ventilation fan 4 is installed on one side of the sliding door 32.

[0035] In the above technical solution, the hanging method is used to realize the suspended installation of the sliding door 32, which will not be affected by the closing of the sliding door 32 by the things falling from the ground, so that the closing of the sliding door 32 is more smooth.

[0036] The speed reducer motor 36 provides driving force to drive the rotation of the screw rod 35. The screw rod 35 cooperates with the threaded sleeve 38 to drive the sliding of the sliding door 32.

[0037] A polygonal stress hole is formed at the end of the screw rod 35 away from the speed reducer motor. When the speed reducer motor 36 is damaged, the screw rod 35 can be manually rotated by using a wrench to cooperate with the stress hole, so as to realize the emergency opening of the sliding door 32.

[0038] A ventilation hole (not shown) is formed in one side of the sliding door 32. The ventilation fan 4 is installed in the ventilation hole.

[0039] As shown in the drawings, Figure 3 The rubber strip 331 is embedded in the two side walls of the sliding groove 33. The dustproof hair 332 is installed by the rubber strip 331. The two side dustproof hairs 332 are partially staggered.

[0040] In the above technical solution, the sealing of the sliding groove 33 is increased to reduce the amount of dust entering.

[0041] The door frame 21 is rounded at the corner positions.

[0042] The rounded transition can reduce the damage caused by collision.

[0043] Referring to Figure 4 As shown, the left and right sides of the sliding door 32 are provided with inclined portions 333, the door frame 21 is made of elastic rubber material, the rib plate 22 and the door frame 21 are in an integrated structure, the rib plate 22 and the door frame 21 are glued and fixed, and the inclined portions 333 correspond to the door frame 21.

[0044] In the above technical solution, the door frame 21 made of elastic rubber material can better seal with the sliding door 32, and the inclined portions 333 can guide and cooperate to avoid the direct impact of the sliding door 32 on the door frame 21 caused by the cooperation error of the sliding door 32 and the door frame 21.

[0045] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited to this, any change or replacement without creative labor should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be limited by the protection scope defined in the claims.
