[0002] Air doors in mine roadways play a crucial role in the mine ventilation system, primarily used to regulate airflow direction, control air volume distribution, and block the diffusion of hazardous gases. Most current air doors are automatic, bi-directional opening doors, but problems persist when used in high-pressure environments. During operation, the increased pressure at high-pressure locations places a burden on the automatic cylinders and auxiliary components, causing frequent malfunctions in the automatic mechanical parts. This results in a significantly higher failure rate compared to other locations, compromising the normal operation of the equipment and the stability of the ventilation system. Furthermore, the high pressure causes delays or rapid opening and closing of the doors when personnel pass through, posing a significant safety risk and posing a high risk of injury to pedestrians.

[0019] This utility model discloses a fast pressure equalization damper regulator and a damper. The following describes one embodiment of this utility model in detail with reference to the accompanying drawings.

[0020] Combination Figure 1 and Figure 2 As shown, the rapid pressure equalizing damper regulator includes a door body 1, limiting components, an adjusting plate 3, and a telescopic cylinder. An air vent is provided at the lower part of the door body 1. The limiting components include a first limiting component 2 and a second limiting component. The first limiting component 2 is located on the left side of the air vent and is fixedly connected to the door body 1. The second limiting component is located on the right side of the air vent and is also fixedly connected to the door body 1. The air vent is located on the lower side between the first limiting component 2 and the second limiting component. The first limiting component 2 and the second limiting component are symmetrical about the air vent, and both the first limiting component 2 and the second limiting component have L-shaped cross-sections. A first sliding groove is formed between the first limiting component 2 and the door body 1, and a second sliding groove is formed between the second limiting component and the door body 1. The adjusting plate 3 is adapted to the air vent; the left part of the adjusting plate 3 is adapted to insert into the first sliding groove, and the right part is adapted to insert into the second sliding groove. Limiting blocks 4 are provided at the bottom of both the first and second sliding grooves, and the limiting blocks 4 are fixedly connected to the door body 1.

[0021] The telescopic cylinder is located above the adjusting plate 3. The cylinder barrel 5 of the telescopic cylinder is hinged to the door body 1 via the first connecting member 7. The first connecting member 7 includes a base plate and two fixed plates. The base plate is fixedly connected to the door body 1. The two fixed plates are symmetrically fixed on the same side of the base plate and are perpendicular to the base plate. Coaxial connecting holes are provided on the two fixed plates. A first sleeve is fixedly connected to the top of the cylinder barrel 5. The first sleeve is adapted to be placed between the two fixed plates. The sleeve is connected to the two fixed plates by a pin, which is used to realize the rotation of the cylinder barrel 5 relative to the door body 1. The piston rod 6 of the telescopic cylinder is hinged to the adjusting plate 3 via a second connecting member. The second connecting member has the same structure as the first connecting member 7. A second sleeve is fixedly connected to the bottom of the piston rod 6. The second sleeve is connected to the second connecting member by a pin. The telescopic cylinder drives the adjusting plate 3 to move up and down along the first slide groove and the second slide groove by telescopic movement, thereby realizing the opening and closing of the air vent.

[0022] Combination Figure 3 and Figure 4 As shown, an air vent includes a door frame 8, a first door leaf 9, and a second door leaf 10. The first door leaf 9 is hinged to the right side of the door frame 8, and the second door leaf 10 is hinged to the left side of the door frame 8. The first door leaf 9 and the second door leaf 10 rotate in opposite directions. A ventilation opening is provided on the first door leaf 9, and a rapid pressure equalization damper regulator is disposed in the ventilation opening. One side of the rapid pressure equalization damper regulator is connected to the first door leaf 9 through several hinges to enable the rapid pressure equalization damper regulator to rotate relative to the first door leaf 9.

[0023] When in use, the airlock is fixedly installed in the tunnel. Due to the large pressure difference on both sides of the airlock, the first door leaf 9 and the second door leaf 10 are prone to rapid opening and closing under the influence of the pressure difference. This not only increases the burden on the mechanical structure used to open and close the airlock, but also poses a safety hazard of workers being pinched when passing through the airlock. To avoid the above problems, before opening the first door leaf 9 and the second door leaf 10, the controller first controls the opening of the telescopic cylinder. The telescopic cylinder retracts and drives the adjusting plate 3 to move upward along the first slide rail and the second slide rail through the piston rod 6, gradually opening the air vent. By pre-balancing the air pressure of the airlock, the pressure difference inside and outside the airlock is balanced before opening the first door leaf 9 and the second door leaf 10. If the controller or the telescopic cylinder malfunctions, the operator can manually open the rapid pressure equalization airlock regulator. The rapid pressure equalization airlock regulator is rotated relative to the first door leaf 9 through the first connecting piece 7 and the second connecting piece to open the ventilation vent on the first door leaf 9 to achieve air pressure pre-balancing. This invention uses the adjusting plate 3 to open the air vent, thereby pre-balancing the air pressure on both sides of the damper. This effectively balances the pressure difference on both sides of the damper, avoiding problems such as difficulty in opening the damper and rapid opening or closing due to air pressure intervention. It effectively improves the smoothness of damper opening and reduces safety hazards.

[0024] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
