Description

Technical Field

[0001] The present invention relates to a mine fire extinguishing device with a dust removal function, belonging to the technical field of mine equipment. Background Art

[0002] A mine is a place for underground mining of mineral resources, which includes a series of facilities such as roadways, shafts, and working faces for miners to enter and exit, mineral transportation, ventilation, and drainage. The main function of a mine is to obtain underground mineral resources to meet the needs of industrial production and social development. Mining operations (such as drilling, blasting, crushing, transportation, etc.) will generate a large amount of dust, which may contain harmful substances such as silicon dioxide (silica dust). Long-term inhalation can lead to occupational diseases such as silicosis and respiratory diseases. Sprinkler dust suppression devices can effectively reduce the concentration of suspended dust in the air and reduce the exposure risk of workers.

[0003] For example, the Chinese utility model patent with the publication number CN221942502U discloses a mobile fire extinguishing device for coal mines, including a vehicle frame, a storage component is fixed at the upper end of the vehicle frame, and an adjustment mechanism is installed on one side of the storage component. The adjustment mechanism includes: a transmission box, the transmission box is fixedly connected to one side of the top of the vehicle frame; a servo motor, the servo motor is fixedly connected to the middle of the top of the transmission box and is internally provided with an angle sensor.

[0004] The above-mentioned solution has the following deficiencies in actual use: This solution adopts a two-station mechanism and a transmission and rotation mechanism composed of a servo motor, a main gear, a transmission gear, a sub-gear, and a turntable. During the spraying and fire extinguishing process, the two groups of nozzles rotate and spray, which can effectively increase the spraying area of the slurry of the device. In actual use, although this solution adopts a two-station mechanism and a specific transmission and rotation mechanism to make the two groups of nozzles rotate and spray to increase the spraying slurry area, in the actual complex mine environment, the adjustment flexibility of its spraying range and angle is limited, it is difficult to accurately cover each dust generation point and the fire area, and moreover, the filtering effect of the spraying liquid of this device is poor, which easily causes the nozzle to be blocked, affecting the dust suppression and fire extinguishing effects, and cannot meet the diverse needs of mine safety production.

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 11 , the present invention provides a technical solution: As Figure 1 and Figure 2 shown, a mine fire extinguishing device with a dust removal function mainly consists of a lower box body 1 and an upper box body 3, which are arranged up and down, and the lower box cover 6 and the upper box cover 7 are respectively rotatably connected through hinges. The lower box body 1 and the upper box body 3 are both internally provided with a first partition 15 and a second partition 16. Among them, a liquid storage cavity is formed between one side of the first partition 15 and the inner wall of the lower box cover 6, and this liquid storage cavity is used to store liquids required for fire extinguishing and dust reduction, such as clear water, fire extinguishing agent solution, etc. A working cavity is formed between one side of the second partition 16 and the inner wall of the upper box body 3. A spraying assembly for dust reduction or fire extinguishing and a driving member for adjusting the position and angle of the spraying assembly are installed in the working cavity. Openings 11 corresponding to the spraying assembly are provided on the upper surface and the left and right sides of the upper box body 3. A flow guide seat 18 is arranged at the bottom of the inner wall of the liquid storage cavity, and its function is to guide the liquid in the liquid storage cavity to the connecting pipe 17 to ensure that the liquid smoothly enters the working cavity and can recycle the excess liquid.

[0022] Further, two fixing bars 2 are provided on the upper surface of the lower box body 1, and two clamping bars 4 corresponding to the fixing bars 2 are provided at the bottom of the upper box body 3. A baffle 5 is provided at the rear ends of the two fixing bars 2. Through the cooperation of the fixing bars 2 and the clamping bars 4, the upper box body 3 can be stably connected to the lower box body 1, preventing displacement during transportation or use. The baffle 5 further plays a role in limiting, ensuring that the upper box body 3 is installed in place and does not slide backward.

[0023] As Figure 3 shown, a control unit 8 is provided on the other side of the first partition 15, which is used to receive the signals of the sensor assembly 9 and control the operation of components such as the driving member and the pump body 31 according to a preset program. A sensor assembly 9 is provided on the other side of the second partition 16. The sensor assembly 9 includes various types such as a dust sensor, a temperature sensor, and a smoke sensor, and can real-time monitor the dust concentration, temperature, and the presence of smoke in the mine, etc., and transmit the data to the control unit 8. A control panel 10 is provided on the outer side wall of the upper box cover 7. An operator can manually control the device through the control panel 10, such as starting, stopping, adjusting the spraying mode, etc. At the same time, the control panel 10 can also display information such as the operating status of the device and sensor data.

[0024] As Figure 11 shown, a protective door 12 is provided in the opening 11. A groove corresponding to the protective door 12 is provided on the side wall of the opening 11 for accommodating the protective door 12, so that when it is closed, it is flush with the surface of the upper box body 3, without affecting the overall structure and aesthetics of the device. Three cylinders 13 are provided on the inner wall of the upper box body 3, and push plates 14 are provided at the output ends of the cylinders 13. The three push plates 14 are respectively connected to the protective door 12. When the spraying assembly needs to be started, the control unit 8 controls the cylinders 13 to extend, and the protective door 12 is pushed open through the push plates 14; when the device is not working or internal components need to be protected, the cylinders 13 retract, driving the protective door 12 to close, preventing dust, sundries, etc. in the mine from entering the working chamber and affecting the normal operation of the device.

[0025] As Figure 4 and Figure 5 shown, the driving member includes a lifting platform 19. A linear motor one 20 for driving the lifting platform 19 to move up and down is provided on the inner wall of the upper box body 3. The linear motor one 20 can accurately control the lifting height of the lifting platform 19, thereby adjusting the vertical position of the spraying assembly to adapt to dust-producing points or fire areas at different heights. The positioning accuracy of the linear motor one 20 ≤ 0.1 mm, and the repeat positioning error < 0.05 mm. A linear motor two 21 is provided on the upper surface of the lifting platform 19, and an angle adjustment assembly is provided on the mover seat of the linear motor two 21. The linear motor two 21 can drive the angle adjustment assembly to move horizontally, further expanding the coverage range of the spraying assembly.

[0026] AsFigure 6 As shown, the angle adjustment component includes a mounting table 22. The upper surface of the mounting table 22 is rotatably connected to a sleeve 24 and a drive shaft 25 respectively through two fixing plates 23. Motors 26 are provided at the ends of the sleeve 24 and the drive shaft 25. An adjustment seat 27 is provided on the sleeve 24. An adjustment shaft 28 is rotatably connected to the adjustment seat 27. Tapered gears 29 are provided at the bottom end of the adjustment shaft 28 and on the drive shaft 25. The two tapered gears 29 are meshed and connected. An adjustment table 30 is provided at the top end of the adjustment shaft 28. When it is necessary to adjust the angle of the spraying component, the control unit 8 controls the motor 26 to operate. The motor 26 drives the drive shaft 25 or the sleeve 24 to rotate. If the drive shaft 25 rotates, through the meshing transmission of the tapered gears 29, the adjustment shaft 28 is driven to rotate, and then the adjustment table 30 rotates, realizing the adjustment of the angle of the spraying component. If the sleeve 24 rotates, the adjustment seat 27 and the components such as the adjustment shaft 28 connected thereto can be driven to rotate as a whole, further increasing the flexibility of angle adjustment.

[0027] As Figure 7 and Figure 8 As shown, the spraying component includes a filter sleeve 34. One side of the bottom of the filter sleeve 34 is provided with an extension pipe 35. The liquid outlet end of the extension pipe 35 is tangent to the inner peripheral surface of the filter sleeve 34. This design can make the liquid entering the filter sleeve 34 form a swirling water flow, improving the filtering effect. The bottom of the filter sleeve 34 is connected to a bottom cover 36 through a flange, which is convenient for disassembling and replacing the internal filter unit 41. The top of the filter sleeve 34 is connected to a diversion cover 37 through a flange. A pipe 38 is provided at the top of the diversion cover 37. The function of the diversion cover 37 is to guide the filtered liquid into the pipe 38 smoothly. A diversion hood 39 is provided at the top end of the pipe 38. A turntable 49 is rotatably connected to the diversion hood 39. A plurality of high-pressure nozzles 50 are provided on the upper surface of the turntable 49. A transmission member for driving the turntable 49 to rotate is provided inside the filter sleeve 34. A pump body 31 is provided at the top of the inner wall of the liquid storage cavity. An inlet pipe 32 is provided at the water inlet of the pump body 31. The inlet pipe 32 is inserted into the liquid storage cavity for sucking liquid. An outlet hose 33 is provided at the water outlet of the pump body 31. The end of the outlet hose 33 is connected to the extension pipe 35. When the pump body 31 works, the liquid in the liquid storage cavity is sucked through the inlet pipe 32, then transported to the filter sleeve 34 through the outlet hose 33 and the extension pipe 35, and finally sprayed out by the high-pressure nozzles 50.

[0028] As Figure 9As shown in the figure, the transmission member includes a transmission shaft 43. A connecting inner ring 46 and a connecting outer ring 47 are arranged on the outer peripheral side of the transmission shaft 43. The connecting inner ring 46 is located inside the connecting outer ring 47. A paddle 48 is arranged between the connecting inner ring 46 and the connecting outer ring 47. When liquid enters the filter sleeve 34 and forms a rotating water flow, the water flow impacts the paddle 48, driving the transmission shaft 43 to rotate. A spiral transmission column 59 is arranged at the top of the transmission shaft 43. The top of the spiral transmission column 59 is connected to the turntable 49. The spiral pitch angle of the spiral transmission column 59 is 30° ± 2°. The pitch has a linear relationship with the rotation speed of the high-pressure nozzle 50. When the transmission shaft 43 rotates, the turntable 49 is driven to rotate through the spiral transmission column 59, enabling the liquid sprayed by the high-pressure nozzle 50 to evenly cover a larger range. Among them, by arranging the spiral transmission column 59, when the spiral transmission column 59 rotates, it will agitate the liquid in the pipeline 38. At the same time, in cooperation with the rotating high-pressure nozzle 50, when the rotating water flow impacts the atomization net 54, the centrifugal force and shear force generated by its rotation will make the distribution of the water flow on the surface of the atomization net 54 more uniform, and can promote the water flow to be further broken into finer water droplets, which helps to improve the atomization effect, making the finally generated water mist more delicate and uniform. Thus, in applications such as dust suppression and humidification, it can be more efficiently mixed with air and play a better role; after the rotating water flow sprays out of the pipeline, its own rotational momentum will make the water flow have stronger penetration power. When extinguishing a fire, this rotating water flow can more powerfully penetrate the flame and reach the core part of the combustible, better realizing the direct cooling and extinguishing of the fire source. Especially for some situations with a large fire and a thick flame, it can more effectively play the role of extinguishing the fire.

[0029] Furthermore, a limiting ring 40 is arranged at the bottom of the inner wall of the filter sleeve 34. Three filtering units 41 are arranged on the limiting ring 40. The filtering units 41 adopt high-precision filter meshes or filter cores, which can effectively filter impurities in the liquid and prevent the nozzles from being blocked. The three filtering units 41 are, in the water flow direction, an 80-mesh stainless steel mesh, a neodymium iron boron magnetic attraction plate, and a 200-mesh nylon filter mesh in sequence, which can effectively separate metal debris and dust. Above the three filtering units 41, a pressing seat 42 is arranged. The pressing seat 42 is in interference fit or threaded connection with the filter sleeve 34 for fixing the filtering units 41. The filtering units 41 are sleeved on the transmission shaft 43. A mounting sleeve 44 is arranged at the bottom end of the transmission shaft 43. A cleaning brush 45 for cleaning the bottom filtering unit 41 is arranged on the outer peripheral side of the mounting sleeve 44. When the transmission shaft 43 rotates, the cleaning brush 45 rotates accordingly to clean the impurities on the surface of the filtering units 41, extending the service life of the filtering units 41 and ensuring the filtering effect.

[0030] As Figure 10As shown in the figure, a base plate 51 is provided at the bottom of the pipeline 38. Rotating connection arms 52 are provided at both ends of the base plate 51. A U-shaped arm 53 is provided at the top of the connection arm 52. Atomizing meshes 54 are provided on the inner side walls of the U-shaped arm 53. Two annular bodies 55 are provided on the outer side wall of the pipeline 38. The upper annular body 55 is fixedly connected to the pipeline 38, and the lower annular body 55 is sleeved on the pipeline 38. A spring 56 is provided between the two annular bodies 55. A connecting plate 58 is rotatably connected between the lower annular body 55 and the two connection arms 52 through a rotating shaft. A connecting part 57 adhered to the lower annular body 55 is provided on the upper surface of the base plate 51. The connecting part 57 is made of a tin-bismuth alloy with a melting point of 75 - 85 °C. When a fire breaks out in the mine, the high temperature will melt the connecting part 57, releasing the fixation of the annular body 55. Under the elastic force of the spring 56, the lower annular body 55 moves upward, driving the connection arm 52 to rotate through the connecting plate 58, causing the U-shaped arm 53 to flip to both sides. At this time, the water sprayed by the high-pressure nozzle 50 directly acts on the fire point to achieve the fire extinguishing effect. During actual use, in order to improve the timeliness of fire extinguishing, a heating coil is provided in the connecting part 57. When the smoke sensor detects a fire, the control unit 8 controls the heating coil to work to melt the connecting part 57.

[0031] The working process of this embodiment is as follows: During daily mine dust suppression operations, the control unit 8 is in a continuous operation state. The dust sensor in the sensor assembly 9 continuously monitors the dust concentration in the mine. When the dust concentration reaches the preset dust suppression threshold, the dust sensor transmits a signal to the control unit 8. After receiving the signal, the control unit 8 immediately starts the pump body 31 and simultaneously controls the cylinder 13 to act. The output end of the cylinder 13 extends, pushing the push plate 14 to open the protective door 12. The liquid in the liquid storage chamber, usually clear water, is sucked into the pump body 31 through the water inlet pipe 32 and then conveyed to the extension pipe 35 through the water outlet hose 33. Since the liquid outlet end of the extension pipe 35 is tangent to the inner peripheral surface of the filter sleeve 34, the liquid forms a rotating water flow after entering the filter sleeve 34. Inside the filter sleeve 34, the liquid is filtered by the filter unit 41. The filter unit 41 can effectively intercept impurities in the liquid to prevent them from clogging the nozzles. At the same time, the rotating water flow impacts the blades 48 in the transmission member, driving the transmission shaft 43 to rotate. The spiral transmission column 59 at the top of the transmission shaft 43 rotates accordingly, and then drives the turntable 49 to rotate, causing the high-pressure nozzles 50 installed on the turntable 49 to spray a rotating water flow. Then the water flow passes through the atomization net 54 on the inner side wall of the U-shaped arm 53 for atomization, forming a finer water mist and a large area of water mist. During this process, if it is necessary to adjust the position and angle of the spraying assembly to better cover the dust-producing area, the control unit 8 will issue instructions according to the actual situation. For example, when it is necessary to adjust the spraying height, the control unit 8 controls the linear motor 1 20 to work, driving the lifting platform 19 to move up and down, thereby driving the entire spraying assembly to rise or fall. If it is necessary to change the horizontal position of the spraying, the linear motor 2 21 is started to drive the angle adjustment assembly and the spraying assembly to move horizontally. When it is necessary to adjust the spraying angle, the control unit 8 controls the motor 26 in the angle adjustment assembly to operate. The motor 26 drives the drive shaft 25 or the sleeve 24 to rotate. Through the meshing transmission of the bevel gears 29, the adjustment shaft 28 rotates, and then the angle adjustment of the adjustment table 30 and the spraying assembly connected to the adjustment table is realized; When a fire breaks out in the mine, the temperature sensor and the smoke sensor in the sensor assembly 9 will quickly detect the abnormality and transmit signals to the control unit 8. After receiving the fire signal, in addition to starting the pump body 31 to increase the liquid delivery volume, at the same time, the high temperature generated by the fire will melt the connecting part 57. The connecting part 57 is usually made of a material such as hot melt adhesive that is easily melted by heat. After the connecting part 57 melts, the lower ring body 55 is no longer fixed. Under the elastic force of the spring 56, it moves upward. The ring body 55 drives the connecting arm 52 to rotate through the connecting plate 58, causing the U-shaped arm 53 to flip to both sides, making the rotating water flow directly act on the ignition point to achieve the fire extinguishing function; During the operation of the device, the cleaning brush 45 on the outer peripheral side of the mounting sleeve 44 at the bottom end of the transmission shaft 43 will clean the filtering unit 41 as the transmission shaft 43 rotates. During regular maintenance, the lower box cover 6 and the upper box cover 7 can be opened to check the filtering effect of the filtering unit 41. If the filtering unit 41 is severely blocked, the pressing seat 42 can be unscrewed to replace the new filtering unit 41. At the same time, check the connection of each component, such as whether there is leakage at the pipe connection, whether the transmission components are operating normally, etc., to ensure that the device is always in good working condition.
