DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 3A ventilated positive pressure explosion-proof room comprises an explosion-proof room body 1 and an explosion-proof pipe 2. The explosion-proof pipe 2 is arranged on one side of the explosion-proof room body 1. A support frame 3 is fixed between the inner walls of the explosion-proof pipe 2 on multiple sides by bolts. A rotating shaft 4 is rotatably inserted between the top and bottom of the support frame 3. A rotating plate 5 is welded on the outer wall of the rotating shaft 4. A worm gear 10 is keyed to the bottom end of the rotating shaft 4. A worm 11 is rotatably connected to the bottom of the explosion-proof pipe 2. The worm 11 is meshed with the worm gear 10. An adjusting wheel 12 is welded at one end of the worm 11. Turning the adjusting wheel 12 drives the worm 11 to rotate, and then the rotating shaft 4 is driven to rotate under the action of the meshing of the worm 11 and the worm gear 10, thereby driving the rotating plate 5 to rotate, thereby adjusting the size of the ventilation. Multiple explosion-proof plates 6 are fixed to the inner walls of the explosion-proof pipe 2 on multiple sides by bolts. The explosion-proof is gradually decelerated by the multiple explosion-proof plates 6. A protective frame 7 is integrally formed on one side of the explosion-proof plate 6.

[0023] A connecting rib 8 is fixed between the inner wall of the explosion-proof pipe 2 and the explosion-proof plate 6 by bolts, thereby improving the firmness of the connection between the explosion-proof pipe 2 and the explosion-proof plate 6. A dust-proof net 9 is clamped at one end of the explosion-proof pipe 2 to prevent dust from entering the explosion-proof pipe 2. A convex plate 13 is fixed to the outer wall of one side of the explosion-proof pipe 2 by bolts. A protective cover 14 is connected to the top of the convex plate 13 by a hinge. The protective cover 14 covers the outside of the adjusting wheel 12 to avoid accidental touching of the adjusting wheel 12 to avoid changing the size of ventilation. Two supporting blocks 15 are cast on the bottom outer wall of the explosion-proof pipe 2 by concrete. An outer wall of one side of the explosion-proof room body 1 is connected to an explosion-proof door 16 by a hinge, and an explosion-proof glass 17 is embedded on one side of the explosion-proof door 16.

[0024] The working principle of this embodiment is as follows: when in use, the explosion-proof pipe 2 is connected with the explosion-proof cabin body 1, so as to facilitate the ventilation of the explosion-proof cabin body 1, and then, the adjusting wheel 12 is turned to drive the worm 11 to rotate, and then the rotating shaft 4 is driven to rotate under the action of the meshing of the worm 11 and the worm wheel 10, thereby driving the rotating plate 5 to rotate, and then adjusting the size of the ventilation, and then, the explosion-proof is gradually decelerated through multiple explosion-proof plates 6.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
