[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] Reference Figure 1 and Figure 2 An embodiment of this utility model is provided: a foldable portable mine local ventilation guide hood, including a mounting ring 1, a folding cover 2 fixedly installed inside the mounting ring 1, and connecting plates 3 provided at both ends of the folding cover 2. A movable rod 7 is provided at the lower end of the mounting ring 1, and a support rod 8 is sleeved at the lower end of the movable rod 7. A fixing plate 12 is installed at the lower end of the support rod 8, and leveling components 13 are provided at the four corners of the fixing plate 12.

[0029] Specifically, the leveling component 13 is used to adjust the fixed plate 12 to be horizontal, then the mounting ring 1 is installed on the upper end of the movable rod 7, and then the height of the movable rod 7 at the upper end of the support rod 8 is adjusted, thereby connecting the two sets of connecting plates 3 to the folding cover 2, which facilitates ventilation of the mine.

[0030] Reference Figure 5 All four leveling components 13 include a positioning piece 131. The positioning piece 131 is fixedly installed on one side of the fixed plate 12. An adjusting rod 132 is inserted into the middle of the positioning piece 131 through a threaded structure. A positioning seat 133 is provided at the lower end of the adjusting rod 132. A first throttle 134 is provided at the upper end of the adjusting rod 132.

[0031] Specifically, after setting the fixing plate 12 to a horizontal position, by rotating the first handle 134 in each of the four sets of leveling components 13, the adjusting rod 132 moves through the threaded structure in the middle position of the positioning piece 131, thereby moving the positioning seat 133 at the lower end of the adjusting rod 132 to a position in contact with the ground, thus ensuring that the fixing plate 12 is set horizontally and preventing the device from tilting due to unevenness.

[0032] Reference Figure 3 Multiple positioning holes 4 are provided on the surface of both sets of connecting plates 3. Sealing gaskets 5 are provided on the side of the two sets of connecting plates 3 that are far apart. Two sets of fixing plates 6 are provided on the lower side of the mounting ring 1, and fixing bolts are provided on the side of the two sets of fixing plates 6 that are far apart.

[0033] Specifically, the positioning holes 4 provided by the connecting plate 3 facilitate the connection of the two sets of folding covers 2. The two sets of connecting plates 3 are provided with sealing gaskets 5 on the opposite sides, which effectively improves the sealing of the ventilation system and prevents airflow leakage. The fixing plate 6 and fixing bolts ensure that the guide cover is fixedly installed on the upper end of the movable rod 7.

[0034] Reference Figure 4 The movable rod 7 is movably inserted into the upper end of the support rod 8, and a fixing bolt is provided at the upper front side of the support rod 8. A rotating rod 9 is inserted into the upper end of the support rod 8, and a gear 10 is provided on the outer side of the rotating rod 9. A matching tooth groove is provided on the rear side of the interior of the movable rod 7. A crank 11 is installed at the right end of the rotating rod 9.

[0035] Specifically, by turning the crank handle 11, the rotating rod 9 is driven to rotate at the upper end of the support rod 8, thereby driving the gear 10 to rotate within the movable rod 7. Through the engagement of the gear 10 and the tooth groove, the movable rod 7, which is movably inserted at the upper end of the support rod 8, is moved, thereby adjusting the height of the folding cover 2 and facilitating the movement of the folding cover 2 to a suitable position.

[0036] Reference Figure 2 Mounting plates 14 are provided on both the front and rear sides of the fixing plate 12, and positioning rods 15 are inserted into the middle of the two sets of mounting plates 14 through a threaded structure. A second handle 16 is provided at the upper end of the positioning rods 15, and the lower ends of the two sets of positioning rods 15 are both set with a tapered structure.

[0037] Specifically, by rotating the second handle 16, the positioning rod 15 moves in the middle position of the mounting plate 14 through the threaded structure. Then, through the cooperation of the tapered structure at the lower end of the positioning rod 15, the positioning rod 15 is easily inserted into the ground to install the device.

[0038] Example 2:

[0039] Reference Figure 6 All four leveling components 13 include a positioning piece 131. The positioning piece 131 is fixedly installed on one side of the fixing plate 12. A positioning sleeve 135 is provided on the upper side of the positioning piece 131. A moving rod 136 is movably inserted in the middle of the positioning sleeve 135. A fixing bolt is provided on the front side of the positioning sleeve 135. A fixing seat 137 is provided at the lower end of the moving rod 136.

[0040] Specifically, after setting the fixing plate 12 to a horizontal position, the position of the positioning piece 131 and the moving rod 136 inside the positioning sleeve 135 are adjusted so that the fixing seat 137 contacts the ground. Then, the moving rod 136 inside the positioning sleeve 135 is fixed by the fixing bolt, thereby ensuring that the fixing plate 12 is set horizontally and preventing the device from tilting due to unevenness.

[0041] Working principle: By operating the four sets of leveling components 13, the fixed plate 12 is leveled. Then, the second handle 16 is rotated so that the positioning rod 15 is inserted into the ground to fix the fixed plate 12. Then, the mounting ring 1 is installed on the upper end of the movable rod 7 through the fixing plate 6 and the fixing bolt. Then, the two sets of folding covers 2 are connected through the connecting plate 3 and the positioning hole 4. Then, by turning the rocker handle 11, the height of the movable rod 7 is adjusted through the rotating rod 9 and the gear 10 so that the folding cover 2 moves to a suitable height. Finally, the height of the movable rod 7 is fixed by the fixing bolt.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
