Description

Technical Field

[0001] The 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 an underground location where mineral resources are extracted. It includes a series of tunnels, shafts, working faces, and other facilities used for miner access, mineral transportation, ventilation, and drainage. The primary function of a mine is to access underground mineral resources to meet the needs of industrial production and social development. Mining operations (such as drilling, blasting, crushing, and transportation) generate large amounts of dust, which may contain harmful substances such as silicon dioxide (silica dust). Long-term inhalation of dust can lead to occupational diseases such as silicosis and respiratory diseases. Water sprinklers can effectively reduce airborne dust concentrations and mitigate worker exposure risks.

[0003] For example, the Chinese utility model patent with announcement number CN221942502U discloses a mobile fire extinguishing device for coal mines, including a frame, a storage assembly is fixed to the upper end of the frame, and an adjustment mechanism is installed on one side of the storage assembly. The adjustment mechanism includes: a transmission box, the transmission box is fixed to one side of the top end of the frame; and a servo motor, the servo motor is fixed to the middle of the top end of the transmission box and has a built-in angle sensor.

[0004] The above solution has the following shortcomings in actual use:

[0005] This solution adopts a double-station mechanism and a transmission 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 sets of nozzles are rotated to spray, which can effectively increase the slurry spraying area of ​​the device. In actual use, although this solution adopts a double-station mechanism and a specific transmission rotation mechanism to rotate the two sets of nozzles to spray to increase the spraying slurry area, in the actual complex mine environment, the adjustment flexibility of the spraying range and angle is limited, and it is difficult to accurately cover various dust-generating points and fire areas. Moreover, the device has a poor filtering effect on the spraying liquid, which can easily cause the nozzle to be blocked, affecting the dust reduction and fire extinguishing effects, and cannot meet the diverse needs of mine safety production.

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] See also Figures 1-11 , the present invention provides a technical solution:

[0037] like Figure 1 and Figure 2As shown, a mining fire extinguishing device with a dust removal function is mainly composed of a lower box body 1 and an upper box body 3, which are arranged in an upper and lower manner and are respectively connected to the lower box cover 6 and the upper box cover 7 by hinges. A partition 15 and a partition 2 16 are provided inside the lower box body 1 and the upper box body 3, wherein a liquid storage chamber is formed between one side of the partition 15 and the inner wall of the lower box cover 6, and the liquid storage chamber is used to store liquids required for fire extinguishing and dust reduction, such as clean water, fire extinguishing agent solution, etc., and a working chamber is formed between one side of the partition 2 16 and the inner wall of the upper box body 3, and a spray assembly for dust reduction or fire extinguishing and a driving member for adjusting the position and angle of the spray assembly are installed in the working chamber. Openings 11 corresponding to the spray assembly are provided on the upper surface and left and right sides of the upper box body 3, and a guide seat 18 is provided at the bottom of the inner wall of the liquid storage chamber, whose function is to guide the liquid in the liquid storage chamber to flow to the connecting pipe 17, ensure that the liquid enters the working chamber smoothly, and can recover excess liquid.

[0038] Furthermore, two fixing bars 2 are provided on the upper surface of the lower box body 1, and two clip bars 4 corresponding to the fixing bars 2 are provided on the bottom of the upper box body 3. The rear ends of the two fixing bars 2 are provided with baffles 5. Through the cooperation of the fixing bars 2 and the clip bars 4, the upper box body 3 and the lower box body 1 can be stably connected to prevent displacement during transportation or use. The baffles 5 further play a limiting role to ensure that the upper box body 3 is installed in place and will not slide backward.

[0039] like Figure 3 As shown, a control unit 8 is provided on the other side of the partition 15 for receiving signals from the sensor assembly 9 and controlling the operation of components such as the drive member and the pump body 31 according to a preset program. A sensor assembly 9 is provided on the other side of the partition 2 16. The sensor assembly 9 includes various types such as dust sensors, temperature sensors, and smoke sensors, which can monitor the dust concentration, temperature, and the presence of smoke in the mine in real time, and transmit the data to the control unit 8. A control panel 10 is provided on the outer wall of the upper box cover 7. The 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 the operating status of the device, sensor data and other information.

[0040] like Figure 11As shown, a protective door 12 is provided in the opening 11, and 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 it is flush with the surface of the upper box body 3 when closed, without affecting the overall structure and appearance 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 component needs to be started, the control unit 8 controls the cylinder 13 to extend and push the protective door 12 to open through the push plates 14; when the device is not working or needs to protect the internal components, the cylinder 13 retracts, driving the protective door 12 to close, thereby preventing dust, debris, etc. in the mine from entering the working chamber and affecting the normal operation of the device.

[0041] like Figure 4 and Figure 5 As shown, the driving part includes a lifting platform 19, and the inner wall of the upper box body 3 is provided with a linear motor 20 that drives the lifting platform 19 to move up and down. The linear motor 20 can accurately control the lifting height of the lifting platform 19, thereby adjusting the vertical position of the spray assembly to adapt to dust-generating points or fire areas at different heights. The positioning accuracy of the linear motor 20 is ≤0.1mm, and the repeat positioning error is <0.05mm. The upper surface of the lifting platform 19 is provided with a linear motor 21, and the mover seat of the linear motor 21 is provided with an angle adjustment assembly. The linear motor 21 can drive the angle adjustment assembly to move horizontally, thereby further expanding the coverage range of the spray assembly.

[0042] like Figure 6 As shown, the angle adjustment assembly includes a mounting platform 22, the upper surface of which is rotatably connected to a sleeve 24 and a drive shaft 25 through two fixing plates 23. The ends of the sleeve 24 and the drive shaft 25 are both provided with a motor 26, and an adjustment seat 27 is provided on the sleeve 24. The adjustment seat 27 is rotatably connected to the adjustment shaft 28. The bottom end of the adjustment shaft 28 and the drive shaft 25 are both provided with a bevel gear 29, which is meshed with each other. The top of the adjustment shaft 28 is provided with an adjustment platform 30. When the angle of the spray assembly needs to be adjusted, the control unit 8 controls the operation of the motor 26, and the motor 26 drives the drive shaft 25 or the sleeve 24 to rotate. If the drive shaft 25 rotates, the meshing transmission of the bevel gear 29 drives the adjustment shaft 28 to rotate, and then the adjustment platform 30 rotates to achieve adjustment of the angle of the spray assembly. If the sleeve 24 rotates, it can drive the adjustment seat 27 and the adjustment shaft 28 connected thereto and other components to rotate as a whole, further increasing the flexibility of angle adjustment.

[0043] like Figure 7 and Figure 8As shown, the spray assembly includes a filter sleeve 34, and an extension tube 35 is provided on one side of the bottom of the filter sleeve 34. The liquid outlet end of the extension tube 35 is tangent to the inner circumference of the filter sleeve 34. This design can make the liquid entering the filter sleeve 34 form a rotating water flow, thereby 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 disassembly and replacement of the internal filter unit 41. The top of the filter sleeve 34 is connected to a flow guide cover 37 through a flange. The top of the flow guide cover 37 is provided with a pipe 38. The function of the flow guide cover 37 is to guide the filtered liquid to smoothly enter the pipe 38. The top of the pipe 38 is provided with a diverter cover 39. A turntable 49 is rotatably connected to the diverter cover 39, and a plurality of high-pressure nozzles 50 are provided on the upper surface of the turntable 49. A transmission part for driving the turntable 49 to rotate is provided in the filter sleeve 34. A pump body 31 is provided on the top of the inner wall of the liquid storage chamber. The water inlet of the pump body 31 is provided with a water inlet pipe 32. The water inlet pipe 32 is inserted into the liquid storage chamber for sucking liquid. The water outlet of the pump body 31 is provided with a water outlet hose 33. The end of the water outlet hose 33 is connected to the extension pipe 35. When the pump body 31 is working, the liquid in the liquid storage chamber is sucked in through the water inlet pipe 32, and then transported to the filter sleeve 34 through the water outlet hose 33 and the extension pipe 35, and finally sprayed out by the high-pressure nozzle 50.

[0044] like Figure 9As shown, the transmission member includes a transmission shaft 43, and the outer circumference of the transmission shaft 43 is provided with an inner connecting ring 46 and an outer connecting ring 47. The inner connecting ring 46 is located inside the outer connecting ring 47, and a paddle 48 is provided between the inner connecting ring 46 and the outer connecting ring 47. When the 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 provided at the top of the transmission shaft 43, and the top of the spiral transmission column 59 is connected to the turntable 49. The spiral rise angle of the spiral transmission column 59 is 30°±2°, and the pitch is linearly related to the rotation speed of the high-pressure nozzle 50. When the transmission shaft 43 rotates, the turntable 49 is driven to rotate by the spiral transmission column 59, so that the liquid sprayed by the high-pressure nozzle 50 can evenly cover a larger range. Among them, by providing the spiral transmission column 59, when the spiral transmission column 59 rotates, The liquid in the pipe 38 is stirred and coordinated with the rotating high-pressure nozzle 50. When the rotating water flow impacts the atomizing net 54, the centrifugal force and shear force generated by its rotation can make the water flow more evenly distributed on the surface of the atomizing net 54, and can prompt the water flow to be further broken into smaller water droplets, which helps to improve the atomization effect and make the final water mist more delicate and uniform, so that it can be more efficiently mixed with the air and play a better role in applications such as dust reduction and humidification; after the rotating water flow is ejected from the pipe, its own rotational momentum will make the water flow have stronger penetrating power. When extinguishing a fire, this rotating water flow can penetrate the flame more forcefully and reach the core of the burning object, so as to better achieve direct cooling and extinguishing of the fire source, especially for some large fires and thick flames, it can more effectively play a fire extinguishing role.

[0045] Furthermore, a limit ring 40 is provided at the bottom of the inner wall of the filter sleeve 34, and three filter units 41 are provided on the limit ring 40. The filter unit 41 adopts a high-precision filter screen or filter core, which can effectively filter impurities in the liquid and prevent the nozzle from being blocked. The three filter units 41 are 80-mesh stainless steel mesh, neodymium iron boron magnetic plate and 200-mesh nylon filter screen in the direction of water flow, which can effectively separate metal debris and dust. A pressing seat 42 is provided above the three filter units 41. The pressing seat 42 is interference fit or threadedly connected to the filter sleeve 34 for fixing the filter unit 41. The filter unit 41 is socketed with the drive shaft 43, and a mounting sleeve 44 is provided at the bottom of the drive shaft 43. A cleaning brush 45 for cleaning the bottom filter unit 41 is provided on the outer peripheral side of the mounting sleeve 44. When the drive shaft 43 rotates, the cleaning brush 45 rotates accordingly to clean the impurities on the surface of the filter unit 41, thereby extending the service life of the filter unit 41 and ensuring the filtering effect.

[0046] like Figure 10As shown, a base plate 51 is provided at the bottom of the pipe 38, and both ends of the base plate 51 are rotatably connected to a connecting arm 52, a U-shaped arm 53 is provided at the top of the connecting arm 52, and an atomizing net 54 is provided on the inner side wall of the U-shaped arm 53. Two ring bodies 55 are provided on the outer side wall of the pipe 38, the upper ring body 55 is fixedly connected to the pipe 38, and the lower ring body 55 is sleeved with the pipe 38. A spring 56 is provided between the two ring bodies 55, and a connecting plate 58 is rotatably connected between the lower ring body 55 and the two connecting arms 52 through a rotating shaft. The upper surface of the base plate 51 is provided with a connecting portion 55 bonded to the lower ring body 55. 7. The connecting portion 57 is made of a tin-bismuth alloy with a melting point of 75-85°C. When a fire occurs in the mine, the high temperature will melt the connecting portion 57, releasing the fixation of the ring body 55. Under the elastic force of the spring 56, the lower ring body 55 moves upward, driving the connecting 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 a fire extinguishing effect. In actual use, in order to improve the timeliness of fire extinguishing, a heating coil is provided in the connecting portion 57. When the smoke sensor detects a fire, the control unit 8 controls the heating coil to melt the connecting portion 57.

[0047] The working process of this embodiment is as follows: during daily mine dust reduction operations, the control unit 8 is in a continuous operation state, and the dust sensor in the sensor assembly 9 monitors the dust concentration in the mine in real time. When the dust concentration reaches the preset dust reduction 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 controls the cylinder 13 to move. The output end of the cylinder 13 extends to push the push plate 14 to open the protective door 12. The liquid in the liquid storage chamber is usually clean water and is sucked into the pump body 31 through the water inlet pipe 32. It is then transported 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 circumference of the filter sleeve 34, the liquid forms a rotating water flow after entering the filter sleeve 34. In the filter sleeve 34, the liquid is filtered through the filter unit 41. The filter unit 41 can effectively intercept impurities in the liquid to prevent it from clogging the nozzle. At the same time, the rotating water flow impacts the blades 48 in the transmission member, driving the transmission shaft 43 to rotate, and the spiral transmission column 59 at the top of the transmission shaft 43 It rotates accordingly, thereby driving the turntable 49 to rotate, causing the high-pressure nozzle 50 installed on the turntable 49 to spray a rotating water flow, and then the water flow passes through the atomizing net 54 on the inner wall of the U-shaped arm 53 to be atomized to form a finer water mist, forming a large-area water mist. In this process, if it is necessary to adjust the position and angle of the spray 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, drive the lifting platform 19 to move up and down, thereby driving the entire spray assembly to rise or fall. If the horizontal position of the spray is to be changed, the linear motor 21 is started to drive the angle adjustment assembly and the spray assembly to move horizontally. When the spraying angle needs to be adjusted, the control unit 8 controls the motor 26 in the angle adjustment assembly to operate, and the motor 26 drives the drive shaft 25 or the sleeve 24 to rotate. Through the meshing transmission of the bevel gear 29, the adjustment shaft 28 is rotated, thereby realizing the angle adjustment of the adjustment platform 30 and the spray assembly connected to the adjustment platform;

[0048] When a fire occurs in the mine, the temperature sensor and smoke sensor in the sensor assembly 9 will quickly detect the abnormality and transmit the signal to the control unit 8. After receiving the fire signal, the control unit 8 will not only start the pump body 31 to increase the liquid delivery volume, but also the high temperature generated by the fire will melt the connecting part 57. The connecting part 57 is usually made of a material that is easily melted by heat, such as hot melt adhesive. After the connecting part 57 melts, the lower ring body 55 is no longer fixed and moves upward under the elastic force of the spring 56. 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, so that the rotating water flow directly acts on the fire point, achieving the fire extinguishing function;

[0049] 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 filter 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 filter unit 41. If the filter unit 41 is seriously clogged, the pressing seat 42 can be unscrewed and a new filter unit 41 can be replaced. At the same time, check the connection status of each component, such as whether there is any leakage at the pipeline connection, whether the transmission components are operating normally, etc., to ensure that the device is always in good working condition.

[0050] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
