DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] Please refer to Figures 1 to 3In an embodiment of the utility model, a novel mine ventilation structure includes an air duct 2, and a bracket mechanism connected to the top of the mine road is arranged at the outer bottom end of the air duct 2. The bracket mechanism includes a support plate 7 for supporting the bottom end of the air duct 2, and connecting columns 4 that penetrate to the top of the support plate 7 are arranged below both ends of the support plate 7. An external thread 6 is opened on the lower half of the outer circumference of the connecting column 4, and a rotating nut 8 threadedly connected to the external thread 6 is arranged at the bottom end of the support plate 7; an adjusting component connected to the top of the mine road is slidably connected inside the upper half of the connecting column 4, and the adjusting component is the top part of the bracket mechanism. The adjusting component is used to adjust according to the concave and convex of the top of the mine road so that the air duct 2 can be installed horizontally.

[0019] In this embodiment: first, the top of the adjusting component is fixed to the top of the mine tunnel. After fixing, observe whether the bottom ends of the four connecting columns 4 are flush. Then, the bottom ends of the four connecting columns 4 are adjusted to a flush state through the adjusting component. After the corresponding air duct 2 is installed, the support plate 7 is aligned from the bottom end of the connecting column 4 and pushed upward. Then, the rotating nut 8 is rotated. The rotating nut 8 moves upward during the rotation process. The upward moving rotating nut 8 pushes the support plate 7 to move upward. The upward moving support plate 7 pushes the air duct 2 to move upward, forming an effective support for the air duct 2, avoiding the entanglement between adjacent air ducts 2, and can better support the air duct 2.

[0020] Please refer to Figure 2 and Figure 3 The adjusting component includes a sliding block 11 which is slidably connected up and down. The sliding block 11 is a rectangular parallelepiped structure, and the top of the sliding block 11 is fixedly connected to an adjusting column 5 which passes through the top of the connecting column 4. A connecting hole 14 is opened at the center of the sliding block 11, and two symmetrically arranged notches 10 are vertically opened on the connecting column 4; the adjusting component also includes an adjusting bolt 12 which is inserted into the inner wall of the connecting hole 14, and an adjusting nut 13 is threadedly connected to the outer periphery of the adjusting bolt 12.

[0021] In this embodiment: during adjustment, by pulling the connecting column 4 to move upward or downward, the connecting column 4 drives the sliding groove 9 to slide along the outer wall of the sliding block 11. When the adjustment is completed, the adjusting bolt 12 is used to pass through the notch 10 and the connecting hole 14, and pass through the other notch 10. Then, the adjusting nut 13 is threadedly connected with the adjusting bolt 12, and the adjusting nut 13 is rotated. After the adjusting nut 13 is tightened, the end faces of the adjusting nut 13 and the adjusting bolt 12 are effectively clamped on the outer wall of the connecting column 4, thereby limiting the connecting column 4 to the adjusted position.

[0022] Please refer to Figure 3 A sliding groove 9 is provided inside the connecting column 4 for the sliding block 11 to slide up and down, and a round hole is provided inside the top of the connecting column 4 for the adjusting column 5 to slide up and down.

[0023] In this embodiment: when the connecting column 4 slides up and down, the sliding groove 9 moves up and down along the outer wall of the sliding block 11, and at the same time, the circular hole moves up and down along the outer wall of the adjusting column 5. Since the cross-sections of the sliding block 11 and the sliding groove 9 are square, the sliding block 11 and the sliding groove 9 can only slide up and down and cannot rotate.

[0024] Please refer with emphasis to Figure 1 , at both ends of the outer periphery of the air duct 2, there is integrally formed a connecting plate 1 formed along the outer periphery of the air duct 2. A plurality of docking holes 3 are opened on the connecting plate 1. The plurality of docking holes 3 are equidistantly distributed along the extending direction of the connecting plate 1. Two adjacent air ducts 2 are connected by a connecting bolt passing through the docking hole 3 and locking with a connecting nut. And a sealing rubber ring is installed on the docking surface of the connecting plate 1 to prevent the air in the air duct 2 from overflowing, or the dusty air in the mine tunnel from entering the inside of the air duct 2.

[0025] In this embodiment: when adjacent air ducts 2 are docked and installed, align the docking end faces of the two air ducts 2. At this time, the connecting plates 1 are aligned with each other, and the connecting plates 1 are aligned with the docking holes 3. Then use a fixing bolt to pass through the docking hole 3, and then use a fixing nut to lock with the fixing bolt, and the two air ducts 2 can be docked and installed. At this time, the rubber sealing ring is deformed under pressure to seal the docking position, preventing the air in the air duct 2 from overflowing, or the dusty air in the mine tunnel from entering the inside of the air duct 2.

[0026] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
