(V) detailed description of the preferred embodiments
The attached drawing is a concrete embodiment of the utility model. This embodiment includes door frame 1 and door leaf 2 with door frame 1 looks articulated, install support 3 on the door frame 1, support 3 is articulated mutually with 4 one end of pneumatic cylinder, the 4 other ends of pneumatic cylinder are articulated mutually with door leaf 2, 2 inboard of door leaf are equipped with a plurality of compartments 5, be equipped with little hydro-cylinder 6 in the compartment 5 of upper portion and lower part respectively, the flexible end connection of little hydro-cylinder 6 is used for fixed door leaf 2 and door frame 1's wedge 7, be equipped with the PLC control box 8 that is connected in the compartment 5 at middle part respectively, hydraulic pressure station 9 and solenoid directional valve 10, PLC control box 8 is connected with level sensor 11. A manual button 12 connected with the PLC control box 8 is arranged outside the door frame 1. A screw 13 is hinged in the compartment 5, and the end part of the screw 13 is connected with a clamping block 14 which can be clamped on the door frame 1. A sealing rubber strip 15 arranged on the door frame 1 is arranged between the door frame 1 and the door leaf 2. The inner side edge of the door frame 1 is provided with a position sensing block 16.
Adopt the utility model discloses a waterproof airtight door of remote automation, when the water inrush in the coal mine tunnel was removed, level sensor 11 sends a signal for PLC control box 8, also can control PLC control box 8 and then control waterproof door through remote interface, perhaps control through local button 12 in advance before the water inrush is future, PLC control box 8 is through the motor that starts hydraulic pressure station 9, control solenoid directional valve 10 action, pneumatic cylinder 4 just can promote door leaf 2 and close the door to door frame 1, position sensor on the door leaf 2 senses position response piece 16 on the door frame 1, the back that targets in place closes, little hydro-cylinder 6 in the compartment 5 starts, it is downthehole to insert the locking of door frame 1 after 2 sides of door leaf to promote wedge 7. When the electric and hydraulic failures happen, the screw 13 can be rotated, and the clamping block 14 can continue to rotate around the screw 13 until the clamping block is clamped on the door frame 1, so that the door frame 1 and the door leaf 2 can be locked. A sealing rubber strip 10 is arranged between the door frame 1 and the door leaf 2, so that the influence of water inflow is avoided. The hydraulic system brakes, the moment is large, the phenomenon that the pressure waterproof door cannot be closed due to water burst can be effectively solved, and better safety is provided. A small oil cylinder 6 is arranged in the door frame, and when the door leaf 2 is closed, the small oil cylinder 6 is pushed out and inserted into the door frame 1, so that the door leaf 2 is further locked.
