Detailed Implementation

[0016] like Figures 1 to 3As shown, this utility model provides a regional centralized control chamber with emergency rescue functions for use in underground coal mines. It includes a control chamber body, inside which lighting, power supply, and water supply equipment are installed. The control chamber body also houses an electrical control module 3 and an emergency rescue module 4, arranged as separate upper and lower units connected by flanges. A water pipe connected to the underground water supply pipeline is installed on the control chamber body, and a solenoid valve is installed on the water pipe. The side of the control chamber body also has terminals for connecting to an external high-voltage AC power supply and a duct for connecting to the mine's compressed air self-rescue system. The control chamber body also contains an emergency rescue kit 12, emergency food, a portable chemical oxygen generator 10, and medical equipment 13.

[0017] The electrical control module 3 includes a host computer component and a communication protection device. The host computer component includes a switch 5, an intrinsically safe display 11, and an explosion-proof and intrinsically safe computer 7. The intrinsically safe display 11 is connected to the explosion-proof and intrinsically safe computer 7 through the switch 5. The switch 5 is connected to the electrical equipment in the coal mine through the communication protection device. The electrical equipment includes coal mining equipment on the fully mechanized mining face, underground ventilation system, conveying system, water pump system, etc., and is used to monitor and control underground equipment and processes to realize functions such as remote centralized control and parameter monitoring.

[0018] The emergency rescue module 4 includes an emergency UPS power supply group 2 and an alarm system. The input terminal of the emergency UPS power supply group 2 is connected to an external high-voltage AC power supply, and the output terminal is connected to the power input of the electrical control module 3. The alarm system is connected to the electrical control module 3. The emergency rescue module 4 is used to achieve emergency activation in the event of an accident, that is, to control the lighting equipment, water supply, compressed air self-rescue system, and other related electrical equipment in the central control unit.

[0019] The control room is made of high-strength, high-temperature resistant, and corrosion-resistant materials, and waterproof material is applied to all joints to ensure its safety. A dedicated emergency rescue area is designated within the room, containing emergency survival kits (12), emergency food, a portable chemical oxygen generator (10), and medical equipment (13). The area of ​​this area is designed to accommodate the number of personnel operating underground, ensuring that the room can adequately accommodate all personnel working underground in the event of an accident.

[0020] like Figure 1As shown, under normal operating conditions in the coal mine, the power converted by the emergency UPS power supply group 2 supplies power to the electrical control module 3. The electrical control module 3 works normally, and the emergency rescue module 4 is in hot standby mode. When an external power failure occurs, the emergency UPS power supply group 2 serves as a backup power supply to the electrical control module 3, and the upper computer of the electrical control module 3 drives the emergency rescue module 4 to be put into operation quickly. At this time, the alarm system sounds an alarm and transmits the signal through the communication line, so that personnel underground and above ground can receive emergency event reminder information. After the alarm signal is transmitted, the electrical control module 3 locks out other functions except for the auxiliary protection of the emergency rescue function to reduce energy consumption in emergency situations.
