Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, and particularly relates to a fire prevention and extinguishing device for coal mines underground. Background Art

[0002] Spontaneous combustion of coal is one of the serious disasters in coal mines. The inducements for underground fires include spontaneous combustion of coal seams, smoldering of conveyor belts at transfer points, etc. An underground vertical shaft that is not directly connected to the ground in a coal mine is called a blind vertical shaft, and an inclined roadway is called a blind inclined shaft. When a fire breaks out in a coal mine underground, it is necessary to extinguish the fire inside to increase the safety of personnel.

[0003] Existing fire prevention and extinguishing devices for coal mines underground usually use fire extinguishers for fire extinguishing. Fire extinguishers can only be used when personnel discover a fire, and cannot effectively give early warnings of fires in flammable areas in coal mines underground. In addition, the volume of fire extinguishers is small, the spraying pressure is weak, and the fire extinguishing effect on coal mines is poor. Therefore, we propose a fire prevention and extinguishing device for coal mines underground to facilitate early warning and fire extinguishing in coal mines underground. Summary of the Utility Model

[0004] Aiming at the problems in the prior art, the utility model provides a fire prevention and extinguishing device for coal mines underground.

[0005] The technical solution adopted by the utility model to solve its technical problems is a fire prevention and extinguishing device for coal mines underground, including a bottom plate. An early warning mechanism is installed at the top of the bottom plate. The early warning mechanism is composed of sleeve A, sleeve B, a support rod, a cross plate, a smoke detection sensor, and a buzzer. Sleeve A is installed at the top of the bottom plate through bolts. Sleeve B is fixedly connected to the inner wall of sleeve A through bolts. The support rod is fixedly connected to the inner wall of sleeve B through bolts. The other end of the support rod is welded to the cross plate. The buzzer is installed at the top of the cross plate. The smoke detection sensor is installed at the top of the cross plate.

[0006] By adopting the above technical solution, when giving an early warning of a fire in a coal mine underground, since the early warning mechanism is installed at the top of the bottom plate and the early warning mechanism is composed of sleeve A, sleeve B, a support rod, a cross plate, a smoke detection sensor, and a buzzer, by loosening the bolts, sleeve B can move inside sleeve A, and the support rod can move inside sleeve B. After adjusting the height of the cross plate, since the smoke detection sensor is installed at the top of the cross plate, after the smoke detection sensor detects coal smoke, the smoke detection sensor transmits the signal to the controller. Then, after the controller receives the signal, the controller controls the buzzer to ring to prompt personnel, thus realizing the early warning of a fire in a coal mine underground and protecting personnel.

[0007] Specifically, it further includes a fire extinguishing mechanism, and the fire extinguishing mechanism is installed at the top of the bottom plate.

[0008] By adopting the above technical solution, the fire extinguishing mechanism can extinguish the coal mine fire point.

[0009] Specifically, the fire extinguishing mechanism is composed of a fire extinguishing tank, a motor, a high-pressure pump, a rotating shaft and blades. A group of fire extinguishing tanks for storing fire extinguishing liquid are installed at the top of the bottom plate. A motor is installed at the top of the fire extinguishing tank. The output end of the motor is installed with a rotating shaft, and blades are installed on the shaft wall of the rotating shaft. A high-pressure pump is installed at the top of the bottom plate, and the input end of the high-pressure pump is connected to the wall of the fire extinguishing tank through a conduit.

[0010] By adopting the above technical solution, when extinguishing a fire in a coal mine underground, since a fire extinguishing mechanism is installed at the top of the bottom plate, and the fire extinguishing mechanism is composed of a fire extinguishing tank, a motor, a high-pressure pump, a rotating shaft and blades. After adding fire extinguishing liquid into the fire extinguishing tank, the motor is controlled by the controller, so that the motor drives the rotating shaft at its output end, and the rotating shaft drives the blades to mix the fire extinguishing liquid in the fire extinguishing tank. Since the wall of the fire extinguishing tank is connected to the input end of the high-pressure pump through a conduit, the high-pressure pump extracts the fire extinguishing liquid in the fire extinguishing tank, and the high-pressure pump is connected to an external conduit. The pressurized fire extinguishing liquid conducts high-pressure fire extinguishing on the fire point, improving the fire extinguishing effect.

[0011] Specifically, a support plate is welded to the wall of the bottom plate.

[0012] By adopting the above technical solution, it is convenient to connect with an external driving part through the support plate to pull the bottom plate.
