Description

Technical Field

[0001] The utility model relates to the technical field of mining production equipment, in particular to an automatic fire extinguishing device for a beltway in an underground mine. Background Art

[0002] At present, in the process of mining and production, belt conveyors are an important transportation equipment in underground mine production. Therefore, the safe and efficient operation of belt conveyors is crucial to improving the overall efficiency of mining and production. The belt conveyor beltway also generally has the risk of fire. When a fire occurs in the underground beltway, a large amount of smoke will be generated, which will have a great impact on the normal operation of the downwind transportation lane and mining plane of the belt conveyor, thereby causing serious impact on the overall mining and production of the mine, and even causing safety accidents. Therefore, optimizing the fire prevention and fire extinguishing device structure of the belt conveyor beltway has an important role in promoting the safety of mining and production and the improvement of the overall efficiency. Utility Model Content

[0003] The utility model provides an automatic fire extinguishing device for a beltway in an underground mine, so as to solve the problems existing in the above background.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] An automatic fire extinguishing device for an underground beltway in a mine, comprising a side plate fixedly arranged on the side of the beltway, a top plate horizontally arranged on the top of the side plate, a PLC controller fixedly arranged on the side of the side plate close to the beltway, an air inlet pipe and a water inlet pipe also being arranged on the side of the side plate, and a solenoid valve being connected to one side of the air inlet pipe and the water inlet pipe, a spray pipe being horizontally connected to the solenoid valve, and the spray pipe being located on the top side of the beltway, a plurality of smoke sensors being fixedly arranged on the bottom of the top plate, and the smoke sensors and the solenoid valves being connected to the PLC controller.

[0006] Furthermore, the spray pipe is evenly provided with a plurality of water spray holes.

[0007] Furthermore, the PLC controller is a Siemens series controller, the solenoid valve is a TQDCF-02 series solenoid valve, and the smoke sensor is a BRJ-301L / T model sensor.

[0008] The utility model has the following beneficial effects:

[0009] The utility model provides an automatic fire extinguishing device for an underground mine beltway, which is mainly composed of top side panels, air inlets, water pipes, solenoid valves, sprinkler pipes, smoke sensors and PLC controllers. By adding side panels and top panels to the sides of the mine beltway, installing water inlets, air ducts and sprinkler pipes on the sides of the side panels, and adding a smoke sensor to the bottom of the top panel at the top of the beltway, the smoke sensor will feed back a fire signal to the PLC controller as soon as a fire occurs on the beltway, and the PLC controller will then control the solenoid valves to allow air and water to enter, thereby extinguishing the fire. In this way, the beltway is efficiently and quickly extinguished, the operation safety of the beltway is effectively ensured, and the overall efficiency of mining transportation is improved. The problem that when dealing with a fire on a conveying beltway in an underground mine, the downwind side of the beltway and the mining platform are usually filled with smoke due to the lack of a dedicated, efficient and timely fire extinguishing device, which ultimately has a significant impact on the overall production safety and efficiency of the mine is solved.

[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] like Figure 1-2 As shown, an automatic fire extinguishing device for an underground beltway in a mine comprises a side panel 1 fixedly arranged on the side of a beltway 10, a top panel 2 being horizontally arranged on the top of the side panel 1, a PLC controller 3 being fixedly arranged on the side of the side panel 1 close to the beltway 10, an air inlet pipe 4 and a water inlet pipe 5 being also arranged on the side of the side panel 1, and a solenoid valve 6 being connected to one side of the air inlet pipe 4 and the water inlet pipe 5, the solenoid valve 6 being also horizontally connected to a spray pipe 7, the spray pipe 7 being located on the top side of the beltway 10, and a plurality of water spray holes 8 being evenly distributed on the spray pipe 7, a plurality of smoke sensors 9 being fixedly arranged on the bottom of the top panel 2, and the smoke sensor 9 and the solenoid valve 6 being both connected to the PLC controller 3.

[0016] When the utility model is used in a specific application, first check whether all parts of the device are well installed, then turn on the power of the device, when a fire occurs on the belt road 10 of the belt conveyor and a large amount of smoke is generated, the smoke sensor 9 detects the fire signal in time, and feeds the signal back to the PLC controller 3 as soon as possible. The PLC controller 3 receives the fire signal and controls the solenoid valve 6 to open, so that the air inlet pipe 4 and the water inlet pipe 5 continue to supply air and water to the sprinkler pipe 7 respectively, and the water flow in the water inlet pipe 5 quickly enters the sprinkler pipe 7 through the pressure of wind, and is sprayed on the belt road 10 through the water spray hole 8, so as to achieve fire extinguishing and control of the fire at the fire place of the belt road 10, effectively ensuring the safety of the operation of the belt conveyor, and thus improving the overall efficiency of mining production.
