Description

Technical Field

[0001] The utility model relates to the technical field of mine ventilation, in particular to a multi-channel mine ventilation door. Background Art

[0002] Since toxic and harmful gases are continuously produced during the underground production process, ventilation must be carried out underground to input fresh air into the mine to increase the oxygen concentration in order to dilute and remove toxic and harmful gases and dust in the mine.

[0003] The mine ventilation doors commonly used in the prior art usually adopt pressure-free balanced dampers. Through the asynchronous and synchronous opening method, the wind pressure acting on the damper is converted into an internal force through the balancing mechanism to balance it. However, the double-door opening method is not conducive to controlling the air volume in the tunnel. Although the prior art adjusts the air volume by adding windows to block the airflow for people or vehicles to pass through.

[0004] However, in actual use, the air volume position cannot be adjusted through the window, which is not conducive to adjusting the path of air flowing into or out of a specific area, resulting in some areas of the mine being unable to get proper ventilation, making the ventilation area more concentrated, which is not conducive to further blocking the leakage of toxic and harmful gases. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1 As shown, the utility model provides a multi-channel mine ventilation door, including a damper body 10, on which at least two groups of movable leaf doors 20 are movably arranged, the movable leaf doors 20 rotate around the connection with the damper body 10 to form a closed structure, a diversion carrier is provided on the movable leaf door 20, and at least three groups of movable leaf blades 30 forming a planar structure are movably arranged on the diversion carrier, and the movable leaf blades 30 rotate around the connection with the movable leaf door 20 and then open to form a multi-channel ventilation structure.

[0027] The utility model adopts a multi-channel adjustable ventilation door structure in the form of a movable connection, and a movable door is composed of a plurality of independently controlled movable blades, thereby forming a multi-channel adjustable ventilation function. The opening range is then controlled by a plurality of groups of movable doors, so that the channel size can be adjusted according to actual use needs to facilitate the passage of pedestrians or vehicles. The opening angle of the channel is further used to guide the ventilation path, thereby adjusting the air volume and the inflow area, so that all areas of the mine can be properly ventilated.

[0028] By independently controlling the rotation amount and angle of the movable blades 30, the ventilation air volume and the air flow path are adjusted, and the ventilation area is guided so that each area in the mine can get appropriate ventilation. Further, by controlling the movable door 20 to make a larger range of adjustments, the size of the mine passage can be adjusted, and a larger ventilation range can be used. Finally, the damper body 10 is used to open and close the whole thing, so that the opening and closing can be adjusted according to actual use needs, and the air volume can be further accurately adjusted.

[0029] like Figure 2 As shown, the flap door 20 includes a first driving mechanism 21 fixedly arranged on the damper body 10 , a door slot 11 matching the flap door 20 is provided on the damper body 10 , and a sliding slot 22 is provided on the outer wall of the flap door 20 .

[0030] The opening and closing of the flap door 20 is controlled by the first driving mechanism 21, and the opening and closing range of the damper body 10 is adjusted by the door slot 11, which is beneficial for opening and closing in a smaller range on the damper body 10, and is beneficial for increasing the opening and closing speed of the damper body 10. The air volume and wind direction are adjusted by controlling the flap door 20.

[0031] like Figure 2 and Figure 3 As shown, a support rod 211 is fixedly installed at the output end of the first driving mechanism 21, and a motor 212 is fixedly arranged at one end of the support rod 211. The output end of the motor 212 is fixedly connected to a connecting shaft 213 matching the slide slot 22 through a coupling. The bottom end of the connecting shaft 213 is slidably connected to the hinged door 20. A protrusion 214 is fixedly installed on the outer wall of the connecting shaft 213. The connecting shaft 213 rotates around the connection with the motor 212 to drive the protrusion 214 to movably abut against the slide slot 22.

[0032] The motor 212 and the connecting shaft 213 are driven to translate by the first driving mechanism 21 and the support rod 211, so as to adjust the position of the connecting shaft 213 on the flap door 20. The first driving mechanism 21 and the connecting shaft 213 are provided at the bottom end of the flap door 20 for synchronous sliding. The flap door 20 rotates around the connecting shaft 213 as the central axis, which is beneficial to adjust the position of the central axis of the flap door 20 and thus adjust the rotation direction of the flap door 20, and further adjust the position and range of the combined rotation opening of multiple groups of flap doors 20, so as to adjust the air volume and the air inflow path.

[0033] like Figure 2 and Figure 4 As shown, the movable blade 30 includes a second driving mechanism 31 fixedly disposed on the movable door 20. The cross section of the movable blade 30 is a Z-shaped structure, and no less than three groups of movable blades 30 abut against each other to form a closed structure.

[0034] The movable blade 30 is controlled to rotate by the second driving mechanism 31, and can be opened and closed in the smallest range, which is convenient for centralized adjustment of the air circulation position and direction. At the same time, the rotation angle of the movable blade 30 is used to further guide the air circulation path, thereby achieving the purpose of guiding air circulation in various areas.

[0035] The Z-shaped structure of the overlapping movable blades 30 is conducive to enhancing the sealing when closed. By independently controlling multiple groups of movable blades 30, the combination of adjusting wind direction can be expanded. By opening and closing different movable blades 30 and movable doors 20, the path of air flowing into or out of a specific area is adjusted, thereby facilitating proper ventilation of various areas in the mine.

[0036] like Figure 1 and Figure 3 As shown, a frame 40 is fixedly provided on the outer wall of the damper body 10, and the damper body 10 is symmetrically arranged with respect to the vertical center line of the frame 40. The opening of the damper body 10 is at the same position as the opening of one side of the flap door 20. A third driving mechanism 41 connected to the damper body 10 is fixedly provided on the frame 40. After the damper body 10 rotates and closes around the connection between it and the frame 40, it drives the flap doors 20 on both sides to move and abut to form a double closed structure.

[0037] The damper body 10 is controlled to open and close through the third drive mechanism 41, which facilitates the maximum range of switching, so that the mine ventilation door can be opened as a whole, thereby facilitating the maximum range of ventilation inside the mine and the passage of vehicles. It can be adjusted through a multi-channel opening and closing method, which can be suitable for different usage scenarios and perform more flexible and accurate opening and closing adjustments, thereby helping to block the leakage of toxic and harmful gases.

The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
