DETAILED DESCRIPTION

[0024] The application is further described in detail below with reference to all the drawings.

[0025] The application discloses a mine suspension type superfine dry powder fire extinguishing device.

[0026] Reference Figure 1 and Figure 2 The mine suspension type superfine dry powder fire extinguishing device comprises a tank body 1, a lifting ring 2 connected to the upper end of the tank body 1, a material conveying pipe 3 and a controller 4 connected to the lower end of the tank body 1, and the controller 4 can be a KXH18(I) mine intrinsic safety type area controller 4, and the material conveying pipe 3 is in communication with the tank body 1. When the mine suspension type superfine dry powder fire extinguishing device is used, the lifting ring 2 is connected with a hook on the top of a roadway or a chamber in a mine, so that the tank body 1 is hung above electromechanical equipment prone to fire. In the embodiment, the material stored in the tank body 1 is superfine dry powder, the superfine dry powder requires a small spraying pressure and has a short spraying distance, and the superfine dry powder has a good fire extinguishing effect on single electromechanical equipment.

[0027] Reference Figure 1 and Figure 3 When the electromechanical equipment catches fire, carbon monoxide, flame and smoke are generated, the controller 4 is electrically connected with a sensing module 5 for monitoring the fire, the sensing module 5 comprises a flame sensor 51, a smoke sensor 52 and a carbon monoxide sensor 53, and the specific models of the sensors can be a GQQ5 mine smoke sensor 52, a GTH1000(A) coal mine carbon monoxide sensor 53 and a GHZ5 mine intrinsic safety type flame sensor 51. The flame sensor 51 is used for detecting whether there is an open flame, the smoke sensor 52 is used for detecting whether there is smoke, and the carbon monoxide sensor 53 is used for detecting the carbon monoxide content.

[0028] Reference Figure 1 and Figure 3 The controller 4 comprises a network communication module 41, a processor 42 and a control module 43, the processor 42 is connected with the network communication module 41, the control module 43 and the sensing module 5, the processor 42 receives signals and sends control signals, when any one of the flame sensor 51, the smoke sensor 52 and the carbon monoxide sensor 53 has an out-of-limit detection result, a signal is sent to the processor 42, and then the processor 42 receives the signal and sends a signal to the control module 43.

[0029] With reference to Figure 2 and Figure 3 , the lower end of the feed pipe 3 is provided with a spray head 31 for spraying the material and an electric ball valve 32 for opening and closing the feed pipe 3, and the electric ball valve 32 can adopt a DFB20 / 7 mine intrinsic safety type electric ball valve 32. The controller 4 is connected with a voice and light alarm 44, which adopts a KXB127 mine explosion-proof and intrinsic safety type voice alarm. When the control module 43 receives a signal that the detection result exceeds the limit, the control module 43 can send a signal to the voice and light alarm 44. The voice and light alarm 44 has a voice alarm countdown function. When the countdown of the voice and light alarm 44 is over, the control module 43 transmits a signal to the electric ball valve 32 to control the electric ball valve 32 to open, and finally the superfine dry powder in the tank 1 flows through the feed pipe 3 and the spray head 31 to be sprayed out, realizing rapid fire extinguishing of the electromechanical equipment.

[0030] With reference to Figure 1 and Figure 3 , the controller 4 is electrically connected with a voltage stabilizing power supply 47 with power storage function, which adopts a KDW127 / 18(B) mine explosion-proof and intrinsic safety type DC voltage stabilizing power supply 47, which can maintain the stable operation of the mine suspended superfine dry powder extinguishing device under power failure. The network communication module 41 receives the control signal sent by the processor 42 and records the received data, which can be transmitted to the ground host computer through the underground industrial ring network.

[0031] With reference to Figure 1 and Figure 3 , the controller 4 is electrically connected with a warning light 45, which can be installed outside the chamber or outside the electromechanical equipment storage place, and the surface of the warning light 45 can be printed with prompt words such as “Do not approach during deflation”. Since the dry powder spraying is toxic and polluting, when the electric ball valve 32 controls the superfine dry powder in the tank 1 to be sprayed, the control module 43 sends a control signal to the warning light 45, and the warning light 45 is turned on to remind the operating personnel not to approach the chamber or the electromechanical equipment storage place.

[0032] With reference to Figure 1 and Figure 3 , the controller 4 is electrically connected with an escape prompt light 46, and the warning light 45 and the escape prompt light 46 both adopt a DHS12LX mine intrinsic safety type signal light. The escape prompt light 46 can be printed with prompt words such as “escape route”. If the personnel in the chamber or the electromechanical equipment storage place do not escape in time, the tank 1 has started to spray dry powder, and the dry powder falls or blocks the line of sight when the personnel escape, when the electric ball valve 32 controls the superfine dry powder in the tank 1 to be sprayed, the control module 43 sends a control signal to the escape prompt light 46, and the escape prompt light 46 is turned on, so that the personnel can leave according to the guidance of the escape prompt light 46.

[0033] With reference toFigure 2 and Figure 3 The branch pipe 33 is detachably connected with the pressure sensor 331 at the end away from the delivery pipe 3, the pressure sensor 331 can be a GPD20 mine pressure sensor 331, and the controller 4 is electrically connected with the pressure sensor 331. The branch pipe 33 and the pressure sensor 331 can be connected together by screw connection, and the delivery pipe 3 is provided with the three-way valve 6 at the connection position of the delivery pipe 3 and the branch pipe 33. When the tank body 1 is not in the spraying state, the three ports of the three-way valve 6 are communicated with the two vertical directions of the delivery pipe 3 and the pressure sensor 331, at this time, the three-way valve 6 is in the initial state, and the pressure sensor 331 is used for monitoring the pressure in the tank body 1 and can transmit the pressure value to the controller 4. When the electric ball valve 32 is opened, the dry powder in the tank body 1 can be normally sprayed out.

[0034] Referring to Figure 2 and Figure 3 When it is needed to fill the dry powder into the tank body 1, the tank body 1 is taken down, the three-way valve 6 is rotated, the delivery pipe 3 is not communicated with the pressure sensor 331, the pressure sensor 331 is detached, the three-way valve 6 is reset, the delivery pipe 3 is communicated with the tank body 1 through the connecting pipe, and the dry powder is filled into the tank body 1. After the filling is completed, the three-way valve 6 is rotated to the delivery pipe 3 blocking state, the pressure sensor 331 is installed, the three-way valve 6 is rotated to the initial state again, and the tank body 1 can be repeatedly used for fire extinguishing. The mine suspension type superfine dry powder fire extinguishing device can quickly fill the fire extinguishing material underground, does not need to go up and down the well for filling, can save more manpower, material resources and time, and improves the timeliness of fire extinguishing of the mechanical and electrical equipment.

[0035] The implementation principle of the mine suspension type superfine dry powder fire extinguishing device is as follows: when the mine suspension type superfine dry powder fire extinguishing device is used, the hook on the top of the underground tunnel or chamber is connected with the lifting ring 2, so that the tank body 1 is hung and placed above the mechanical and electrical equipment prone to fire. In this embodiment, the material stored in the tank body 1 is superfine dry powder, which has small spraying pressure, short spraying distance and good fire extinguishing effect for single mechanical and electrical equipment. When any one of the fire sensor 51, the smoke sensor 52 and the carbon monoxide sensor 53 detects an over-limit result, a signal will be sent to the processor 42, and then the processor 42 receives the signal and sends a signal to the control module 43. The control module 43 can send a signal to the voice and light alarm 44, and the voice and light alarm 44 starts the countdown. After the countdown is over, the control module 43 transmits a signal to the electric ball valve 32 to control the electric ball valve 32 to open, and finally the superfine dry powder in the tank body 1 flows through the feeding pipe 3 and the spray head 31 to realize rapid fire extinguishing of the mechanical and electrical equipment. When it is necessary to fill the tank body 1 with dry powder, the tank body 1 is removed, the three-way valve 6 is rotated to make the feeding pipe 3 not communicate with the pressure sensor 331, the pressure sensor 331 is removed, the three-way valve 6 is reset, the feeding pipe 3 is connected with the connecting pipe to fill the tank body 1 with dry powder. After filling is completed, the three-way valve 6 is rotated to the feeding pipe 3 blocking state, the pressure sensor 331 is installed, and the three-way valve 6 is rotated to the initial state again, so that the tank body 1 can be reused for fire extinguishing. The underground rapid filling of fire extinguishing materials can save a lot of manpower, material resources and time, and improve the timeliness of fire extinguishing of mechanical and electrical equipment.
