Description
Technical Field
[0001] The utility model relates to the technical field of fire extinguishing equipment, in particular to an automatic fire extinguishing equipment for preventing coal mine fires. Background Art
[0002] Coal is the main energy source in my country, accounting for about 70% of primary energy, but the coal industry is also a high-risk industry. Accidents such as gas, fire, landslide, and coal dust hinder the safe production of coal mines. Fires in coal mines mainly include fires in goaf areas and tunnels, which are difficult to detect, develop rapidly, and are difficult to extinguish. Once a fire occurs, if it cannot be controlled in time, the scope of involvement will expand rapidly, causing a large number of casualties.
[0003] In the early stage of a coal mine fire, the fire must be extinguished in a timely and comprehensive manner. However, the existing fire extinguishing equipment nozzle structure can only rotate. In the early stage of a fire, the nozzle cannot swing and spray during the rotation process, and thus cannot quickly extinguish the surrounding fire. In addition, during the process of spraying and extinguishing the fire, due to the small spraying range of the nozzle, flames still exist in some corners due to the nozzle not spraying in place, causing the fire to reignite in the later stage. This reduces the fire extinguishing effect of the automatic fire extinguishing equipment. Utility Model Content
[0004] The utility model aims at the deficiencies in the prior art and provides the following technical solutions: an automatic fire extinguishing device for preventing coal mine fires, comprising a water supply main pipe, a spherical body slot is provided on the outer side of the water supply main pipe, a spherical body pipe is movably connected to the spherical body slot, a swinging water pipe is fixedly installed on the outer surface of the spherical body pipe, a rotating water pipe is movably connected to the swinging water pipe, a thread groove is provided on the inner ring surface of the rotating water pipe, a connecting thread is provided on the outer side of the swinging water pipe, the thread groove on the inner side of the rotating water pipe is connected to the connecting thread on the outer side of the swinging water pipe through a thread, a connecting spherical body is fixedly installed on the surface of the rotating water pipe and located near the middle, a horizontal power-assisting plate is movably connected to the surface of the connecting spherical body, an inclined pipe is fixedly installed on the outer side of the rotating water pipe and located near the bottom, and a fire extinguishing nozzle is provided on the outer side of the inclined pipe.
[0005] As an improvement of the above technical solution, a fixed baffle is provided at the left end of the water supply main pipe, an electric push rod is fixedly installed on the right side of the fixed baffle, the telescopic end of the electric push rod is fixedly installed on the left end of the horizontal power-assisting plate, a mounting bracket is fixedly installed on the outside of the water supply main pipe and close to the fixed baffle, and a smoke alarm is provided on the surface of the water supply main pipe and close to the swinging water pipe.
[0006] As an improvement of the above technical solution, an arc limiting groove is opened on the outer side of the water supply main pipe, and the arc limiting groove is connected with the spherical groove. An arc limiting block is fixedly installed on the surface of the spherical pipe, and the arc limiting groove and the arc limiting block are movably connected. The spherical pipe is restricted by the movably connected arc limiting groove and the arc limiting block, so that the spherical pipe can only rotate in the horizontal plane.
[0007] As an improvement of the above technical solution, the top end of the inclined tube is lower than the bottom end of the horizontal power-assisting plate, so as to prevent the inclined tube from colliding with the horizontal power-assisting plate during the rotation process.
[0008] As an improvement of the above technical solution, there are multiple smoke alarms, and the multiple smoke alarms are evenly arranged on the outside of the water supply main, so that fires can be discovered in time.
[0009] The beneficial effects of the utility model are as follows: when the smoke alarm detects a fire, the fire extinguishing nozzle can swing and cross-spray water to quickly extinguish the fire by cooperating with the structures such as the rotating water pipe and the spherical tube during the rotation, thereby preventing the fire from spreading and expanding the spraying range of the fire extinguishing nozzle, making it easier for the fire extinguishing nozzle to extinguish the flames in the corners in time and preventing the possibility of re-ignition at a later time, thereby improving the fire extinguishing effect of the automatic fire extinguishing equipment.

The thread groove 23 on the inner side of the rotating water pipe 22 is threadedly connected to the connecting thread 24 on the outer side of the swinging water pipe 21. A connecting spherical body 25 is fixedly installed on the surface of the rotating water pipe 22 and located near the middle. A horizontal power-assisting plate 26 is movably connected to the surface of the connecting spherical body 25. An inclined pipe 27 is fixedly installed on the outer side of the rotating water pipe 22 and located near the bottom. The top of the inclined pipe 27 is lower than the bottom of the horizontal power-assisting plate 26 to prevent the inclined pipe 27 from colliding with the horizontal power-assisting plate 26 during rotation. A fire extinguishing nozzle 28 is provided on the outer side of the inclined pipe 27.
[0016] A fixed plugging plate 3 is provided at the left end of the water supply main pipe 1, an electric push rod 4 is fixedly installed on the right side of the fixed plugging plate 3, the telescopic end of the electric push rod 4 is fixedly installed on the left end of the horizontal power-assisting plate 26, a mounting bracket 5 is fixedly installed on the outside of the water supply main pipe 1 and at a position close to the fixed plugging plate 3, a smoke alarm 6 is provided on the surface of the water supply main pipe 1 and at a position close to the swinging water pipe 21, there are multiple smoke alarms 6, and the multiple smoke alarms 6 are evenly arranged on the outside of the water supply main pipe 1, so that the multiple smoke alarms 6 can facilitate timely detection of fire.
[0017] The water pipe 1 is installed on the top of the coal mine cave by installing the bracket 5. When the smoke alarm 6 detects a fire, water flows through the spherical pipe 2 and is sprayed out by the fire extinguishing nozzle 28 to spray and extinguish the fire. At the same time, the electric push rod 4 is started. When the electric push rod 4 extends and drives the horizontal assisting plate 26 to move to the right, the horizontal assisting plate 26 drives the rotating water pipe 22 to swing to the right with the spherical pipe 2 as the center through the connected spherical body 25. The rotating water pipe 22 drives the swinging water pipe 21 to swing to the right with the spherical pipe 2 as the center. The rotating water pipe 22 drives the inclined pipe 27 and the fire extinguishing nozzle 28 to swing to the right synchronously. When the rotating water pipe 22 swings to the right, the distance between the rotating water pipe 22 and the spherical pipe 2 becomes longer, so that the rotating water pipe 22 is The water pipe 22 moves relatively to the lower right side. When the rotating water pipe 22 moves relatively to the lower right side, the threaded connection is performed through the threaded groove 23 and the connecting thread 24 to make the rotating water pipe 22 rotate. The rotating water pipe 22 drives the tilting pipe 27 to rotate, and the tilting pipe 27 drives the fire extinguishing nozzle 28 to rotate. Similarly, the working principle of the electric push rod 4 contracting and driving the horizontal assisting plate 26 to move to the left is the same as above. In the initial stage of a fire, the fire extinguishing nozzle 28 sprays water to extinguish the fire. The fire extinguishing nozzle 28 swings and cross-sprays water during the rotation process to quickly extinguish the fire, thereby expanding the spraying range of the fire extinguishing nozzle 28, so that the fire extinguishing nozzle 28 can promptly extinguish the flames in the corner to prevent the possibility of re-ignition in the later stage.
