[0062] The above-mentioned pipeline can be buried in the bottom plate or the side of the tunnel 100, and extend in sequence along the extension direction of the tunnel 100 until it reaches the last safety chamber 200.

[0063] The positioning device 5 is used to locate the position in the tunnel 100 to provide data for the subsequent determination of the location of the emergency accident and the selection of a suitable safety chamber 200. Multiple sets of positioning devices 5 are arranged at intervals along the extension direction of the tunnel 100. The positioning device 5 is equipped with a position sensor, a loudspeaker, a camera, etc. The electronic devices in the positioning device 5 are connected to the control device 1 through a wire to achieve signal transmission. The personnel at the display screen of the control device 1 can observe the scene around each positioning device 5 through the screen display, and can also make voice calls to communicate with the personnel around the positioning device 5. Each staff member entering the mine is equipped with a personnel identification card, which has a positioning chip.

After the underground worker presses the "help" button, the control device 1 will display the "help" position according to the positioning function to start the rescue plan.

[0065] Each safety chamber 200 is equipped with a rescue vehicle 6, an emergency rescue pipe 7, a converter 8 and a backup power supply.

[0066] The converter 8 is fixedly installed in the safety chamber 200. The converter 8 is respectively connected to the pipes of the water supply equipment 2, the ventilation equipment 3 and the nutrient solution supply equipment 4. On the one hand, it is used to transfer water, fresh air and nutrient solution to the safety chamber 200. On the other hand, it is also used to transfer water / fresh air and nutrient solution to the emergency rescue pipe 7.

[0067] Specifically, the converter 8 is provided with a water supply connector 81, an air supply connector 82 and a nutrient solution supply connector 83. The water supply connector 81, the air supply connector 82 and the nutrient solution supply connector 83 are respectively provided with a control valve 84 for controlling the on and off of each connector. The control valve 84 is preferably an electromagnetic control valve, which is controlled by the control device 1.

[0068] The converter 8 further includes a water supply interface connected to the water supply connector 81, an air supply interface connected to the air supply connector 82, and a nutrient solution supply interface connected to the nutrient solution supply connector 83. The pipeline of the water supply device 2 is connected to the water supply interface so that water can be directed to the water supply connector 81. The pipeline of the air supply device 3 is connected to the air supply interface so that wind can be directed to the air supply connector 82. The pipeline of the nutrient solution supply device 4 is connected to the nutrient solution supply interface so that the nutrient solution can be directed to the nutrient solution supply connector 83.

[0069] The water supply connector 81, the air supply connector 82 and the nutrient solution connector 83 each have two outlets, each of which is provided with a control valve 84. The first outlet is arranged in the safety chamber 200, similar to a faucet, for personnel to receive water, breathe ventilation, and drink nutrient solution. The second outlet is connected to the emergency rescue pipe 7 to transfer water / fresh air and nutrient solution to the emergency rescue pipe 7.

[0070] Considering that during underground rescue, nutrient solution must be carried and supplied, and the situation where water and fresh air are supplied at the same time is rare, in order to reduce the diameter of the emergency rescue pipe 7, the emergency rescue pipe 7 adopts the following structural design:

[0071] The emergency rescue pipe 7 adopts a flexible pipe, which can be coiled in the safety chamber 200 and put away in normal state. When in use, it can be pulled into the tunnel 100 or into the depth of the well by the rescue trolley 6. The length of the emergency rescue pipe 7 can be designed according to needs.

[0072] The emergency rescue pipe 7 adopts a double-layer structure, which includes a central pipe 71 and an outer sleeve 73. The outer sleeve 73 is sleeved on the central pipe 71, and an annular channel 74 is formed between the outer sleeve 73 and the central pipe 71. The central pipe 71 transfers nutrient solution, and the annular channel 74 is used to select water or air supply.

[0073] The head end of the emergency rescue tube 7 is fixedly connected to the converter 8 , and the tail end of the emergency rescue tube 7 is connected to the rescue vehicle 6 , so that it can move with the rescue vehicle 6 .

[0074] The air supply connector 82 and the water supply connector 81 are respectively connected to the head end of the outer sleeve 73 and are respectively communicated with the annular channel 74. By controlling the switch of the control valve 84 in each connector, water or air can be supplied to the annular channel 74.

[0075] The nutrient solution supply connector 83 is connected to the head end of the central tube 71, and the tail end of the central tube 71 is connected to the telescopic nozzle 72. When the central tube 71 supplies the nutrient solution, the telescopic nozzle 72 extends out of the outer sleeve 73 so as to extend into the mouth of the person to be rescued, or it is convenient for the person to be rescued to open his mouth and suck the telescopic nozzle 72 to squeeze the nutrient solution into his mouth. The nozzle of the telescopic nozzle 72 preferably adopts a silicone sleeve so as to squeeze out the nutrient solution. The power of the liquid pump can be set as needed to avoid a large amount of nutrient solution being sprayed out and wasted.

[0076] As required, an electromagnetic valve can be configured at the head end of the central tube 71, and a liquid level sensor can be configured at the tail end of the central tube 71. The electromagnetic valve and the liquid level sensor are respectively connected to the control device 1 by signal. When the liquid level sensor detects that there is nutrient solution at the tail end of the central tube 71, the control device 1 closes the electromagnetic valve, and the nutrient solution in the central tube 71 is sufficient for multiple people to replenish, thereby reducing the loss caused by the continuous supply of nutrient solution.

[0077] The rescue vehicle 6 is used to tow the emergency rescue pipe 7 to the designated place, and is also used to monitor the surrounding environment. The rescue vehicle 6 includes a body 60 and a walking mechanism 61 arranged at the bottom of the body. The walking mechanism 61 can adopt a crawler mechanism. A control unit 62 is provided in the body 60, such as a chip, a controller, etc., which is used to control the operation of electrical components and signal transmission of the rescue vehicle 6. The control unit 62 is connected to the control device 1 by signal, and can transmit the received signals to the control device 1 for display, judgment and selection by the control device 1. A power mechanism 63 is provided in the body 60, such as a hydraulic drive mechanism or an electric drive mechanism, which is used to drive the walking mechanism 61 forward, backward or turn.

[0078] The vehicle body 60 is provided with a smoke / dust sensor 64, a temperature sensor 65, a positioning chip 66 and a monitoring camera 67. The smoke / dust sensor 64, the temperature sensor 65, the positioning chip 66 and the monitoring camera 67 are respectively connected to the control unit 62 through wires for transmitting signals.

[0079] The smoke / dust sensor 64 is used to monitor the smoke condition, dust concentration, etc. of the place. The smoke / dust sensor 64 can be a combination of a smoke sensor and a dust sensor, or an integrated sensor with smoke monitoring function and dust monitoring function.

[0080] If the smoke concentration is too high, a fire may occur. If the dust concentration is too high, the monitoring camera 67 may not be able to shoot clearly and the rescue personnel may have difficulty breathing. When the smoke concentration is too high, water is supplied to the annular channel 74 to spray on the fire scene to suppress the spread of the fire. When the dust concentration is too high, air is supplied to the annular channel 74 to blow the dust and the like in a safe direction.

[0081] The temperature sensor 65 is used to monitor the temperature of the place, and if the smoke concentration is too high and the temperature is higher than normal temperature, it is judged that a fire may occur. At this time, water is supplied to the annular channel 74 to spray on the fire scene to suppress the spread of the fire.

[0082] The positioning chip 66 locates the position of the rescue vehicle 6 and transmits the position signal to the control unit 62 .

[0083] The monitoring camera 67 is used to shoot the scene at the location, and the screen can show whether anyone has not escaped, whether there is a fire, smoke, thick dust, etc. The monitoring camera 67 transmits the above signal information to the control unit 62.

[0084] The above-mentioned various judgments are comprehensively judged based on the signals of the smoke / dust sensor 64, the temperature sensor 65 and the monitoring camera 67, and then a suitable rescue plan is selected.

[0085] The top of the vehicle body 60 is provided with a pipe clamp 68 , which can be a sleeve. The tail end of the emergency rescue pipe 7 passes through the pipe clamp 68 and is fixed.

[0086] The method for emergency rescue using the underground positioning emergency system provided by the present invention is as follows:

[0087] The first step: after an emergency accident occurs underground, the location where the emergency accident occurred is located using the positioning device 5.

[0088] Step 2: Determine one or more safety chambers 200 that are close to the emergency accident site and currently safe.

[0089] Step 2: Control the rescue vehicle 6 in the selected safety chamber 200 to move, the rescue vehicle 6 pulls the emergency rescue pipe 7 toward the emergency accident site, monitors the surrounding environmental factors in real time, and executes emergency rescue measures, including:

[0090] If the monitoring camera 67 captures that there are people who have not yet left the dangerous place, the location of the people can be seen from the screen display, and the rescue vehicle 6 is controlled to move through the screen display so that the tail end of the emergency rescue tube 7 is facing the people, and then the telescopic nozzle 72 is extended toward the people to be rescued, and nutrient solution begins to be supplied in the central tube 71. The people to be rescued can get nutrient solution from the telescopic nozzle 72, which helps to replenish physical energy and escape from the predicament.

[0091] If the monitoring camera 67 captures thick smoke or fire, the smoke / dust sensor 64 detects thick smoke, and the temperature sensor 65 detects that the ambient temperature is too high, the rescue vehicle 6 is controlled to move through the screen display so that the tail end of the emergency rescue pipe 7 is directed toward the fire scene, and water is supplied to the annular channel 74 to spray the water toward the fire scene to suppress the spread of the fire.

[0092] If the monitoring camera 67 captures a dust accumulation area, and the smoke / dust sensor 64 detects that the dust concentration is too high and ventilation is required, the rescue vehicle 6 is controlled to move through the screen display so that the tail end of the emergency rescue pipe 7 is directed toward the dust accumulation area, and air is supplied to the annular channel 74 to blow the wind toward the dust accumulation area to disperse the dust.

[0093] In order to facilitate the movement of the rescue vehicle 6 and reduce its load during movement, the emergency rescue pipe 7 is an empty pipe before the situation requiring rescue is detected. After the situation requiring rescue is detected, nutrient solution is supplied to the central pipe, or water / wind is supplied to the annular channel 74.

[0094] The power of the water pump and the fan can be selected according to needs to meet the requirements of water spraying and air blowing.

[0095] In order to prevent the wires, wires, optical fibers, etc. connected to the rescue vehicle 6 from being in disarray and worn out by gravel in the lane 100, the wires, wires, optical fibers, etc. can be wrapped on the outer sleeve 73 with adhesive tape and moved integrally with the emergency rescue tube 7.

[0096] To sum up, the underground positioning emergency system provided by the present invention, after an emergency accident occurs, uses the rescue vehicle 6 to tow the emergency rescue pipe 7 toward the site of the emergency accident, and monitors the surrounding environmental factors in real time to implement different emergency rescue measures. It can provide nutrient solution to the rescued personnel, suppress the spread of underground fires, and reduce the dust concentration underground to improve the accuracy of video monitoring, which greatly improves the emergency rescue effect and efficiency and reduces the difficulty of later rescue.
