[0021] The temporary ventilation structure can be fixed by the support seat 1 and the insertion tube 2, and the length of the width adjustment component 4 can be adjusted according to the length of the curtain 5 through the installation rod 41 and the two adjustment tubes 42 in the width adjustment component 4, and the installation of the curtain 5 can be completed by cooperating with the limit plate 43. The sleeve 31 and the adjustment rod 32 in the height adjustment component 3 will drive the mounting seat 33 with the curtain 5 to rise and fall. When the top of the curtain 5 contacts the top of the alley, the height of the temporary ventilation structure can be adjusted according to the height of the alley by cooperating with the locking rod and the locking hole. Through the above steps, the size of the temporary ventilation structure can be adjusted according to the actual size of the alley, thereby expanding the application scope of the temporary ventilation structure. Since the support seat 1 adopts a dual reinforcement method of bolt fixing and weight increase, it not only greatly improves the stability and wind resistance of the temporary ventilation structure, but also facilitates the transportation of the temporary ventilation structure.

[0022] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The height adjustment assembly 3 includes a sleeve 31 movably connected to the insert sleeve 2, an adjustment rod 32 is slidably connected to the sleeve 31, locking holes are provided on the surface of the sleeve 31 and the surface of the adjustment rod 32, a locking rod is threadedly connected to the locking hole, and a mounting seat 33 is fixedly connected to the top of the adjustment rod 32. The sleeve 31 is inserted into the insert sleeve 2 connected to the support seat 1, and then the width adjustment assembly 4 with the curtain 5 is placed in the mounting seat 33 fixedly connected to the top of the adjustment rod 32, and then the adjustment rod 32 is pulled upward to slide upward along the sleeve 31 until the top of the curtain 5 contacts the top of the lane, and the locking rod is tightened to pass through the locking holes provided on the surface of the sleeve 31 and the adjustment rod 32 in turn, so that the height of the temporary ventilation structure can be adjusted according to the height of the lane.

[0023] The surface of the sleeve 31 is fixedly connected with a support frame 13 below the locking hole, and the top of the mounting seat 33 near the curtain 5 is arc-shaped. The support frame 13 can provide additional support force for the locking rod, thereby improving the support effect of the height adjustment component 3 on the curtain 5 installed on the top of the width adjustment component 4. The top of the mounting seat 33 near the curtain 5 is arc-shaped so that the mounting seat 33 can fit the surface of the curtain 5 more closely, which is beneficial to reduce the wear of the mounting seat 33 on the curtain 5 when installing the temporary ventilation structure.

[0024] The width adjustment assembly 4 includes a mounting rod 41 movably connected to the top of the height adjustment assembly 3. Two adjustment cylinders 42 are threadedly connected to the surface of the mounting rod 41. The side of the adjustment cylinder 42 away from the mounting rod 41 is threadedly connected to a limit plate 43. The adjustment cylinder 42 is movably connected to the curtain 5. The curtain 5 of a suitable length is selected according to the width of the lane, and then the two adjustment cylinders 42 threadedly connected to the surface of the mounting rod 41 are rotated according to the length of the curtain 5 so that the two adjustment cylinders 42 move away from each other along the surface of the mounting rod 41. After the width adjustment assembly 4 is adjusted to a suitable length as a whole, the curtain 5 is placed on the surface of the adjustment cylinder 42, and then the limit plate 43 is screwed into the adjustment cylinder 42 to complete the installation of the curtain 5.

[0025] An anti-skid layer is provided inside the inserting tube 2, and an anti-skid pattern is fixedly connected to one end of the anti-skid layer away from the inserting tube 2. The anti-skid layer can prevent the sleeve 31 from rotating inside the inserting tube 2 after being inserted therein.

[0026] The number of the hanging rings 11 is the same as the number of the hooks 12, and each hanging ring 11 corresponds to each hook 12 one by one. The bottom of the curtain door 6 can be fixed by hanging each hook 12 to each hook 12 surface at the corresponding position.

[0027] The installation method of the utility model is as follows: first, the support seat 1 is fixed to the preset position with bolts, and then weight-increasing objects such as stones are filled into the support seat 1 to increase the weight of the support seat 1 to improve the stability of the support seat 1 when placed, and then the sleeve 31 is inserted into the plug-in sleeve 2 connected in the support seat 1, and then the curtain 5 of appropriate length is selected according to the width of the lane, and then the two adjusting cylinders 42 threadedly connected to the surface of the mounting rod 41 are rotated according to the length of the curtain 5 so that the two adjusting cylinders 42 move away from each other along the surface of the mounting rod 41, and after the width adjustment assembly 4 is adjusted to a suitable length as a whole, the curtain 5 is placed on the surface of the adjusting cylinder 42, and then the limit plate 43 is screwed into the adjusting cylinder 42 to complete the installation of the curtain 5, and then the width adjustment assembly 4 with the curtain 5 is placed in the top of the adjusting rod 32 fixedly connected. The bracket 33 is fixed to the top of the support base 1, and then the adjusting rod 32 is pulled upward to slide it upward along the sleeve 31 until the top of the curtain 5 contacts the top of the tunnel, and then the locking rod is tightened to pass through the locking holes on the surface of the sleeve 31 and the adjusting rod 32 in turn. Then, stones or the like can be used to further fix the lower end of the curtain 6. Through the above steps, the size of the temporary ventilation structure can be adjusted according to the actual size of the tunnel, thereby expanding the scope of application of the temporary ventilation structure. Since the support base 1 adopts a dual reinforcement method of bolt fixing and weight adding, it not only greatly improves the stability and wind resistance of the temporary ventilation structure, but also facilitates the transportation of the temporary ventilation structure.

[0028] The working principle of the utility model is: when the wind is blocked normally, the temporary ventilation structure will Figure 1 As shown, the wind flow cannot blow away the mutual attraction between the two first magnetic strips 7 located at the connection between the two curtain doors 6, nor can it blow away the mutual attraction between the two second magnetic strips 10 located at the connection between the curtain door 6 and the curtain window 8, thereby achieving the purpose of blocking the wind in the mine.

[0029] When ventilation is required, refer to Figure 5 , rotate the curtain window 8 in the direction away from the curtain door 6 so that the two second magnetic strips 10 are separated from each other, and then one end of the curtain window 8 can be fixed to the side of the curtain door 6 through the Velcro 9, and the curtain window 8 will be opened for ventilation.

[0030] When people pass through the temporary ventilation structure, refer to Figure 4 The worker removes the stone pressing the curtain 5 and pushes the curtain door 6 so that the two first magnetic strips 7 respectively connected to the two curtain doors 6 are separated from each other, thereby facilitating the passage of people. After that, the two first magnetic strips 7 connected to the two curtain doors 6 will automatically close by relying on the mutual attraction between the two.

[0031] When encountering the overflow of shock waves caused by impact ground pressure or blasting during tunnel excavation, such as Figure 5 As shown, the mutual attraction between the two second magnetic strips 10 will be broken by the impact force, and the curtain window 8 connected to the curtain door 6 will be in the open state at this time. Figure 4 The shock wave will rush through the temporary ventilation structure from the gap between the curtain door 6 and the curtain window 8, and the temporary ventilation structure will not be damaged. After the impact, the curtain door 6 and the curtain window 8 will automatically close by relying on the magnetic force of the first magnetic strip 7 and the second magnetic strip 10 respectively to continue to block the wind.

[0032] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
