Description

Technical Field

[0001] The invention relates to the technical field of mine fire extinguishing, and in particular to a fire sprinkler fire extinguishing system for mines. Background Art

[0002] As the coal industry enters the era of scientific and technological production, the importance of safe production is becoming increasingly important. Coal fire is one of the five major disasters in mine safety production. Its effective prevention and control is the main guarantee to ensure mine safety production. Therefore, an efficient fire prevention and extinguishing system is particularly important.

[0003] After searching, it was found that the invention patent "application number is 202010917140.0, and the patent name is a large space sprinkler fire extinguishing device for coal mine fires". Through the attraction of the magnet to the pressure plate of the iron material, and the tension of the spring and the gravity of the pressure plate itself, the pressure plate is in a balanced state in the initial state, and the gas in the first cavity and the water in the second cavity will not flow out. The excessive temperature will cause the airbag to expand, and the expanded airbag will expand to move the second sliding block that is against each other. Because the connecting rod is connected to drive the first sliding block to push the extrusion plate upward, the extrusion plate squeezes the air in the first cavity and drives the magnet to move upward, so that the pressure plate loses the attraction of the magnet and the pressure plate will be pressed down, and the water in the second cavity will flow out from the spray, so as to extinguish the fire and slow down the fire;

[0004] Although the above device can effectively extinguish fires on a large scale in mines, the device has the following disadvantages when in use: the expansion of the airbag is the power source for pushing the second slider to move, but the expansion of the airbag relies on the evaporation of liquid water into water vapor. Although water can begin to evaporate before reaching the boiling point, the speed is much lower than the evaporation speed at boiling, and the airbag is inside the mounting block, which will cause the airbag to heat more slowly, reduce the evaporation rate of liquid water, and thus slowly push the second slider, affecting the spraying of water flow, which is not conducive to the fire extinguishing work.

The upper side of the liquid outlet pipe 51 passes through the fire box 10 and extends to the outside thereof. The liquid outlet pipe 51 is equipped with a nozzle 50 for spraying the mixed liquid, thereby realizing fire extinguishing in the mine.

[0042] The water tank 30 is an airbag made of composite materials, which combines different types of materials together, so that the water tank 30 has good elasticity and durability, can be stretched later, and can withstand a certain amount of pressure.

[0043] The water tank 30 is configured as a double layer, the outer layer is a wear-resistant rubber layer, and the inner layer is a silicone rubber layer with good elasticity; silicone rubber has good heat resistance, cold resistance, chemical resistance and electrical insulation, good elasticity, and is not easy to age, so that the water tank 30 as a whole can withstand high temperatures and can also be deformed.

[0044] An air outlet is provided on the upper side of the water tank 30 , and when the water tank 30 is deformed by force, the excess gas in the water tank 30 can be discharged to avoid explosion caused by excessive pressure in the water tank 30 .

[0045] The bottom side of the mixing box 40 is configured in a triangular shape, which can increase the flow range of the water in the water outlet pipe 34 sprayed into the mixing box 40.

[0046] A rotating rod 45 is rotatably connected in the mixing box 40, and a stirring blade 44 is fixedly connected to the bottom side of the rotating rod 45. The rotation of the stirring blade 44 can ensure that the water and the salt solution are fully mixed;

[0047] A transmission motor 42 is provided on the upper side of the rotating rod 45, and a protective box 43 is covered on the outer side of the transmission motor 42. The protective box 43 is fixedly connected to the upper outer wall of the fire extinguishing box 10; the bottom side of the output end of the transmission motor 42 is fixedly connected to the upper side of the rotating rod 45, which is used to provide power for the rotating rod 45 to rotate.

[0049] A smoke sensor is installed on the right outer wall of the control box 20, and an infrared camera is installed on the front outer wall of the control box 20. Both are used to monitor the fire status in the mine in real time. The coordinated use of the smoke sensor and the infrared camera can effectively improve fire monitoring.

[0050] The smoke sensor and the infrared camera are electrically connected to the controller through wires respectively.

[0051] The control box 20 and the fire extinguisher box 10 are both provided with wire outlet holes, which are used for external power supply of electrical components such as battery blocks and water pumps 33; at the same time, the rear end face of the fire extinguisher box 10 can also be provided with heat dissipation holes to dissipate heat inside the box.

[0052] During the actual operation of the embodiment of the present application, a certain amount of water (at least two-thirds of the total capacity of the water tank 30) is injected into the water tank 30, and a certain amount of salt solution (at least one-half of the total capacity of the mixing box 40) is injected into the mixing box 40. The electrical components on the fire extinguishing box 10 and the control box 20 are in normal working condition. The smoke sensor and the infrared camera monitor the mine conditions in real time. When there is a fire, its signal is transmitted to the controller. The controller receives the signal and starts the water pump 33 and the transmission motor 42 at the same time. The water in the water tank 10 enters the mixing box 40 through the water inlet pipe 32, the water pump 33, and the water outlet pipe 34.

[0053] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: the cooperation between the smoke sensor and the infrared camera can transmit the fire condition to the controller in the first time, so that the fire can be extinguished in the first time; and the mixture of water and salt solution can increase the boiling point of water, reduce evaporation, and enable water to remain liquid at higher temperatures, thereby improving the fire extinguishing effect.

[0054] It should be noted that since the nozzle sprays water outwards by water pressure, if all the water in the water tank is transported to the mixing tank, in order to avoid the waste of liquid in the mixing tank, a water pump can be added to the liquid outlet pipe as needed to increase the liquid outlet power.

[0055] Embodiment 2

[0056] See also Figure 4 , 6When the nozzle 50 sprays liquid, in order to ensure that the nozzle 50 can spray over a large range, eliminate certain spraying dead angles, and ensure that fire sources at relatively far or relatively close locations can also be effectively extinguished, an adjustment component 70 is designed.

[0057] The adjustment assembly 70 is arranged on the right side of the fire extinguishing box 10, and is located at the rear side of the water tank 30; the adjustment assembly 70 is provided with two groups, and the other group of adjustment assembly 70 is symmetrically arranged on the left side of the fire extinguishing box 10; the adjustment assembly 70 includes a support frame 71, a motor 72, a rotating shaft 74, and a sleeve 75;

[0058] The support frame 71 is fixedly connected to the inner wall of the bottom side of the fire extinguisher box 10, and is arranged in an inverted L shape for installation support of the motor 72; the motor 72 is fixedly connected to the support frame 71, and is used to provide power for the rotation of the rotating shaft 74; the rotating shaft 74 is rotatably connected to the inner wall of the bottom side of the fire extinguisher box 10, and is arranged as a threaded rod; the sleeve 75 is sleeved on the outer side of the rotating shaft 74, and a threaded hole is provided therein, and the rotating shaft 74 is rotatably connected to the sleeve 75 through the thread.

[0059] The upper side of the sleeve 75 is fixedly connected with a support plate 61 , and the upper end surface of the support plate 61 is slidably connected with a slider 1 62 and a slider 2 65 , and the slider 1 62 is located on the left side of the slider 2 65 .

[0060] The motor 42 and the rotating shaft 74 are connected via a belt 73 for driving the rotating shaft 74 to rotate.

[0061] A support rod 60 is slidably connected inside the fire extinguisher box 10 and is located at the rear side of the mixing box 40; a connecting block 1 64 and a connecting block 2 67 are fixedly mounted on the support rod 60; a mounting rod 1 81 is fixedly connected to the upper side of the connecting block 14, and a mounting rod 2 82 is fixedly connected to the upper side of the connecting block 2 67; the upper sides of the mounting rod 1 81 and the upper sides of the mounting rod 2 82 both pass through the upper side of the fire extinguisher box 10 and extend to the outside thereof, and the mounting rod 1 81 and the mounting rod 2 82 are both slidably connected to the fire extinguisher box 10; a mounting seat 80 is fixedly connected between the mounting rod 1 81 and the mounting rod 2 82, and the nozzle 50 is fixedly connected to the mounting seat 80.

[0062] A connecting rod 1 63 is connected between the slider 1 62 and the connecting block 1 64, and the connecting rod 1 63 is rotatably connected to the slider 1 62 and the connecting block 1 64 respectively; a connecting rod 2 66 is connected between the slider 2 65 and the connecting block 2 67, and the connecting rod 2 66 is rotatably connected to the slider 2 65 and the connecting block 2 67 respectively.

[0063] The front end surface of the support rod 60 is fixedly connected to the rear end surface of the mixing box 40. The mixing box 40 is configured to have a similar structural design to the water tank 10, that is, the mixing box 40 is configured to have a double layer, the outer layer is a wear-resistant rubber layer, and the inner layer is a silicone rubber layer with good elasticity;

[0064] When the support rod 60 slides upward, the mixing box 40 can be appropriately tightened, thereby pushing the liquid in the mixing box 40 upward, so that the nozzle 50 can spray liquid over a large area and a large amount of water to extinguish a fire at a distant location.

[0065] The front half of the upper end face of the support plate 61 is located on the upper side of the water tank 30 (but on the rear side of the water pump 33). When the support plate 61 moves downward, it can apply a certain pressure to the water tank 30, causing the water tank 30 to shrink downward and pressurize the water in the tank. The pressure is higher than the external environment of the water tank, and the water will be pushed toward the water inlet pipe 32, accelerating the entry of water.

[0066] The water inlet pipe 32, the water outlet pipe 34 and the liquid outlet pipe 51 are all configured as retractable metal hoses, which can prevent the water inlet pipe 32 and the water outlet pipe 34 from being broken when the water tank 30 and the mixing box 40 are deformed; similarly, the liquid outlet pipe 51 can be prevented from being broken when the mounting seat 80 moves up and down.

[0067] The motor 72 is electrically connected to the controller via a wire.

[0068] It should be noted that the up and down movement range of the support rod 60 is not too large, and is within the deformation tolerance range of the mixing box 40 to ensure the normal use of the mixing box 40 and the water tank 10.

[0069] During the actual operation of the embodiment of the present application, during the spraying process of the nozzle 50, the controller simultaneously turns on the motor 72, and the motor 72 drives the rotating shaft 74 to rotate clockwise or counterclockwise, thereby pushing up or pulling down the sleeve 75, and realizing the up and down movement of the support plate 61; when the support plate 61 moves up, the slider 1 62 and the slider 2 65 slide in opposite directions, and the support rod 60 is pushed up through the connecting rod 1 63 and the connecting rod 2 66, thereby realizing the upward movement of the mounting seat 80, and when the support rod 60 slides up, it can appropriately tighten the mixing box 40, thereby pushing the liquid in the mixing box 40 upward, so that the nozzle 50 50 can spray liquid over a large area and with a large amount of water to extinguish a fire at a distant location; when the support plate 61 moves downward, the slider 1 62 and the slider 2 65 slide in opposite directions, and the support rod 60 is pulled down via the connecting rod 1 63 and the connecting rod 2 66, thereby realizing the downward movement of the mounting seat 80. When the support plate 61 moves downward, a certain pressure can be applied to the water tank 30, causing the water tank 30 to shrink and pressurize the water in the tank. The water will be pushed toward the water inlet pipe 32, and the water pump 33 cooperates to accelerate the water flow into the mixing box 40, so that the nozzle 50 can quickly spray the liquid to the fire at a nearby location for extinguishing.

[0070] The technical scheme in the above-mentioned embodiment of the present application has at least the following technical effects or advantages: the nozzle is adjusted up and down at the same time when spraying liquid, which can ensure that the nozzle sprays over a large range, eliminates certain spraying dead angles, and ensures that fire sources at farther or closer locations can also be effectively extinguished; and when the nozzle moves up, the support rod can slide up and tighten the mixing box appropriately, thereby pushing the liquid in the mixing box upward, so that the nozzle can spray liquid over a large range and with a large amount of water to extinguish fires at farther locations; when the nozzle moves down, the support plate can apply a certain pressure to the water tank when it moves down, so that the water tank shrinks and pressurizes the water in the box. The water will be pushed to the water inlet pipe, and the water pump cooperates to accelerate the water flow into the mixing box, so that the nozzle can quickly spray the liquid to the fire at a closer location for extinguishing.

[0071] After the fire is extinguished in the later stage, water and salt solution should be added to the water tank and mixing tank in time.

[0072] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
