Description

Technical Field

[0002] In mine operations, the ventilation system is one of the essential mining facilities. The ventilation system directly affects the safety of workers in the mine. It not only needs to ensure the smooth breathing of workers but also carry dust out of the mine to control the dust concentration. Currently, the commonly used ventilation method is to send air from the outside into the deep mine by a fan, and then realize the return air through the air ducts in the mine. Moreover, a wind window needs to be set at the opening of the air duct for blocking. The wind window blocking usually adopts a grid structure. In the ventilation system, air doors also need to be set in the mine roadway to ensure that the air sent from the outside does not directly flow out of the mine roadway. The air door and the air window complement each other. However, the problem with the existing air door and air window structures in actual use is that since the opening size of the grid cannot be adjusted, when the opening of the grid is too small, the return air efficiency will be affected; while when the opening of the grid is too large, or even when the grid is not installed, the air velocity in the air duct will be too high, thus affecting the overall air circulation effect of the ventilation facilities. In addition, the adjustment of the wind window is different from that of an ordinary window. The former requires more delicate adjustment to accurately control the air velocity. Therefore, the industry urgently needs an air door and air window control system that can automatically control the opening and closing of the air door and automatically adjust the air velocity of the air window.

[0033] Please continue reading Figures 1 to 5Before the ventilation system is put into operation, the wind speed sensor 3 is first set to a preset range for sending a signal. When the detected wind speed is higher than the preset upper limit, the wind speed sensor 3 will send a window closing signal to reduce the aforementioned adjustable wind window 2 until the wind speed drops to the preset range. When the wind speed is lower than the preset lower limit, the wind speed sensor 3 sends a window opening signal to increase the aforementioned adjustable wind window 2 until the wind speed rises to the preset range. The working principle of the aforementioned adjustable wind window 2 is as follows: the aforementioned pneumatic motor 213 is controlled to work, and the aforementioned pneumatic motor 2 The power of 13 is decelerated by the reducer 212 and the reduction box 211, so that the output shaft 2111 and the driving disk 214 rotate slowly. The aforementioned adjusting rod 215 also slides in the long hole 2411 and moves upward or downward with the rotation of the driving disk 214, thereby driving the aforementioned driving plate 241 and the connecting rod 24 to move upward or downward. During the displacement process, the aforementioned connecting rod 24 pulls the connecting ear 234, so that the corresponding windshield plate 23 rotates around its respective hinge ear bolt 2331, thereby adjusting the size of the aforementioned air outlet 11. The working principle of the aforementioned wind window control box 4 is as follows: when the aforementioned wind window controller 41 receives a window closing signal, the wind window controller 41 controls the first ball valve I411 to rotate, so that the gas of the gas source 46 enters the first exhaust valve I44 through the first ball valve I411, and the gas enters the pneumatic motor 213 after passing through the aforementioned first exhaust valve I44 and the first exhaust valve connecting pipe I441. At this time, the aforementioned pneumatic motor 213 rotates forward to close the wind deflector 23, and the gas passing through the aforementioned pneumatic motor 213 is discharged from the second exhaust valve II45 through the second exhaust valve connecting pipe II451; when the aforementioned wind window controller 41 receives a window opening signal, the wind window controller 41 controls the second ball valve II41 2 rotates, so that the gas of the gas source 46 enters the second exhaust valve II45 through the second ball valve II412, and the gas enters the pneumatic motor 213 through the second exhaust valve II45 and the second exhaust valve connecting pipe II451. At this time, the pneumatic motor 213 reverses to open the wind deflector 23, and the gas passing through the pneumatic motor 213 is discharged from the first exhaust valve I44 through the first exhaust valve connecting pipe I441; when it is necessary to manually control the aforementioned adjustable wind window 2, the aforementioned wind window closing button 42 or the aforementioned wind window opening button 43 is pressed, and the gas also enters the pneumatic motor 213 through the first exhaust valve I44 or the second exhaust valve II45 to close or open the wind deflector 23.

[0034] At the same time, in order to prevent the air flow from flowing out of the mine tunnel and causing the wind speed at the aforementioned regulating window 2 to drop significantly, the aforementioned dampers 5 are arranged at intervals in the mine tunnel and are opened and closed in sequence when pedestrians or mine cars pass by to avoid direct ventilation between the mine tunnel and the outside world. When the staff needs to enter from one side of the damper 5, they long press the aforementioned first door opening button Ⅰ73 to open the air path at the first door opening button Ⅰ73, and the gas enters the left reversing port 612 of the two-position five-way valve along the channel between the first door opening button Ⅰ73 and the second door opening button Ⅱ62, so that the two-position five-way valve air inlet 611 and the left air outlet 614 of the two-position five-way valve 61 are open, and the gas filtered by the aforementioned filter 72 passes through the two-position five-way valve air inlet 611 in sequence. 11.
