Description
Technical Field
[0001] The present invention relates to the technical field of coal mine ventilation, in particular to a coal mine ventilation and regulating device. Background Art
[0002] Inside coal mines and other mines, the oxygen concentration is relatively low, and there are toxic and harmful gases and dust in the air. Therefore, ventilation equipment is needed to bring fresh air into the interior to ensure the safety of people inside the mine.
[0003] For example, a regulating device for regulating the ventilation volume of a coal mine with the announcement number CN219865104U includes a ventilation pipe, a fixed block fixedly connected to the side wall of the ventilation pipe, a groove formed at the lower end of the fixed block, an electric turntable fixedly connected to the groove, an output end of the electric turntable passes through the side wall of the ventilation pipe and is fixedly connected to a vertical rod, and air is sucked in from the outside and blown into the coal mine through a reduction motor and a one-way blade. When the air passes through, it drives the fan blades to rotate, and the fan blades drive the cleaning brush to rotate through the rotating rod, and the cleaning brush can clean the dust on the filter screen to prevent the filter screen from being blocked; the electric turntable, the vertical rod, and the first bevel gear can drive the second bevel gear to rotate, and the second bevel gear will drive the first baffle to rotate through the cross bar, so that the ventilation hole is dislocated, thereby The ventilation volume is adjusted according to the actual situation to prevent the air beam from short-circuiting. However, during the same construction period, in order to provide sufficient ventilation volume and ensure the air circulation and dilution of harmful gases in the mine, the rotation speed of the ventilation fan blades in the mine will basically not slow down. When the fan is damaged or the components are aged, the rotation speed of the ventilation fan blades may decrease. Since the maintenance of the ventilation duct is generally a positioning inspection, it is difficult to detect the reduction in the rotation speed of the ventilation fan blades in time, which will affect the normal supply of ventilation volume in the mine and even cause safety risks. Dust is easily accumulated on the surface of the ventilation duct in the mine, which not only affects the ventilation effect, but also may cause safety hazards. The existing direct spray dust reduction structure is not convenient for collecting the dust and droplet combination after spraying, and it is easy to cause the combination to accumulate on the inner wall of the ventilation duct, affecting the smooth ventilation.
[0004] Therefore, a coal mine ventilation and conditioning device is proposed to solve the above-mentioned problems. Summary of the Invention

[0028] Compared with the prior art, the present invention has the following beneficial effects:
[0029] 1. By setting the adjustment component, start the motor, the motor drives the shaft and the fan blade to rotate, the fan blade draws air through the air inlet filter, the air inlet filter plays a filtering role, the shaft drives the fixed sleeve to rotate, the fixed sleeve drives the outer rod and the sleeve to rotate, the arc sleeve is subjected to centrifugal force, it will stretch the spring 2 and throw it out, and the elastic coefficient of the spring 2 is greater than the elastic coefficient of the spring 1, so that the arc sleeve will squeeze the arc plates on both sides, the arc plates compress the spring 1 and slide on the fixed rod. When the motor fails or ages, the speed of the shaft slows down. At this time, the elastic force of the spring 2 will drive the arc sleeve to slide toward the outer rod, so that the arc sleeve expansion distance is reduced, and the spring The elastic force of one drives the arc plate to move, the arc plate drives the screw rod and the movable plate to move, and the movable plate drives the contact switch to move, so that the contact switches on both sides are in contact and conductive. At this time, the warning light is on to warn, which is convenient for the operator to find the fault in time and perform maintenance operations. By loosening the tightening bolt and moving the initial position of the adjustment sleeve, it is convenient to indirectly adjust the diameter of the subsequent centrifugal rotation of the arc sleeve, so as to facilitate the adjustment of the expansion distance of the arc plates on both sides. By rotating the upper and lower screw rods, it is convenient to horizontally adjust the position of the movable plate and the contact switch, so as to adapt to the change of the expansion position of the arc plate and keep the two contact switches in normal contact to achieve the adjustment of the air volume.
[0030] 2. The wind extracted by the fan blades is transported between the arc plates and the annular groove. The rotation of the shaft also drives the installation sleeve to rotate, and the installation sleeve drives the guide rod and the rotating rod to rotate. The rotating rod throws out and stretches the spring three. The air hole at one end of the rotating rod is connected to the annular groove, which is convenient for the extracted wind to pass through. When the speed of the shaft decreases, the elastic force of the spring three drives the rotating rod to slide closer to the installation sleeve. The area of communication between the air hole and the annular groove is reduced, which reduces the air intake of the pipeline body and can also help warn the operator. This solves the problem that when the fan is damaged or the speed is reduced due to aging of components, the operator is difficult to find in time, which in turn affects the normal supply of mine ventilation.
[0031] 3. By setting up a dust removal component, the water pipe is connected to the external pressurized water body during operation. The pressurized water passes through the fixed ring and the rotating part and is sprayed out by the bifurcated nozzle. The bifurcated nozzle includes two vertical and inclined nozzles. The vertical nozzle sprays the gas to reduce dust, and the recoil of the water sprayed from the inclined nozzle will drive the bifurcated nozzle and the rotating part to rotate. The collection filter filters the water after spraying, and the guide block guides the cleaning brush. When the cleaning brush rotates to the top of the collection filter, the elastic force of the spring four drives the pressure plate and the cleaning brush to press down, so that the cleaning brush wipes and cleans the top of the collection filter, thereby reducing the clogging of the collection filter, improving the collection effect after spraying, and solving the problem of inconvenience in collecting the combination of dust and droplets after spraying, which easily causes the combination to accumulate on the inner wall of the ventilation duct.

An air hole is opened inside the end of the rotating rod 424 away from the rotating shaft 42, and the position of the air hole is flush with the annular groove 427. A rotating groove 426 is opened inside the side of the annular member 45 close to the motor 41, and the rotating rod 424 is rotatably connected to the rotating groove 426.
[0057] A dust removal assembly 5 is provided on the other side of the interior of the pipe body 1. The dust removal assembly 5 includes a forked nozzle 54 symmetrically mounted inside the pipe body 1. A pressure plate 56 is slidably mounted on the outer side of the forked nozzle 54, and a cleaning brush 58 is fixedly connected to the outer side of the pressure plate 56.
[0058] Example 1: Figure 4-11 As shown, start the motor 41, the motor 41 drives the rotating shaft 42 and the fan blade part 43 to rotate, the fan blade part 43 draws air through the air inlet filter 2, and the air inlet filter 2 plays a filtering role. The rotating shaft 42 drives the fixed sleeve 416 to rotate, and the fixed sleeve 416 drives the outer rod 417 and the sleeve 418 to rotate. The arc sleeve 421 is subjected to centrifugal force, which will stretch the spring 2 420 and throw it out, and the elastic coefficient of the spring 2 420 is greater than the elastic coefficient of the spring 1 410, so that the arc sleeve 421 will squeeze the arc plates 48 on both sides, and the arc plates 48 compress the spring 1 410 and slide on the fixed rod 47.
[0059] When the motor 41 fails or ages, the rotation speed of the rotating shaft 42 slows down. At this time, the elastic force of the second spring 420 will drive the arc sleeve 421 to slide toward the outer rod 417, so that the expansion distance of the arc sleeve 421 is reduced. The elastic force of the first spring 410 drives the arc plate 48 to move. The arc plate 48 drives the screw rod 411 and the movable plate 412 to move. The movable plate 412 drives the contact switch 413 to move, so that the contact switches 413 on both sides are in contact and conductive. At this time, the warning light 415 lights up to warn, making it easier for the operator to find the fault in time and perform maintenance operations.
[0060] By loosening the fastening bolt 419 and moving the initial position of the adjustment sleeve 418, the diameter of the subsequent centrifugal rotation of the arc sleeve 421 can be indirectly adjusted, thereby facilitating the adjustment of the expansion distance of the arc plates 48 on both sides. By rotating the upper and lower screw rods 411, the position of the movable plate 412 and the contact switch 413 can be horizontally adjusted to adapt to the change in the expansion position of the arc plate 48, thereby maintaining normal contact between the two contact switches 413 and achieving air volume adjustment.
[0061] The wind extracted by the fan blade part 43 is transported through the arc plate 48 and the annular groove 427. The rotation of the rotating shaft 42 will also drive the installation sleeve 422 to rotate, and the installation sleeve 422 drives the guide rod 423 and the rotating rod 424 to rotate. The rotating rod 424 throws out and stretches the spring three 425. The air hole at one end of the rotating rod 424 is connected to the annular groove 427, which facilitates the passage of the extracted wind.
[0062] When the rotation speed of the rotating shaft 42 decreases, the elastic force of the spring three 425 drives the rotating rod 424 to slide closer to the mounting sleeve 422, and the area of the connection between the air hole and the annular groove 427 is reduced, so that the air intake of the pipeline body 1 is reduced, and it can also assist in warning the operator, solving the problem that when the fan is damaged or the components are aged, causing the rotation speed to decrease, the operator is difficult to discover in time, which will affect the normal supply of ventilation in the mine.
[0063] The top of the collecting box 3 is symmetrically fixedly connected with a guide block 7, which is located on both sides of the top of the collecting filter 6. The dust removal assembly 5 also includes a fixed ring 51 fixedly connected to one side of the pipe body 1. The two collecting filters 6 are respectively located on both sides of the fixed ring 51. A water receiving pipe 52 is fixedly installed on the top of the outer side of the fixing ring 51, and a rotating part 53 is rotatably installed on the inner side of the fixing ring 51.
[0064] The water receiving pipe 52 is connected to the rotating part 53 through the fixed ring 51, and the bifurcated nozzle 54 is symmetrically fixedly installed on the inner side of the rotating part 53. Side rods 55 are symmetrically fixedly installed on both sides of the rotating part 53. The pressure plate 56 is slidably connected to the side rods 55, and the outer side of the side rods 55 is sleeved with springs 57.
[0065] Spring four 57 is located on the side of the pressure plate 56 away from the fixed ring 51. One side of the spring four 57 is fixedly connected to the pressure plate 56, and the other side of the spring four 57 is fixedly connected to the end of the pressure plate 56.
[0066] Example 2: Figure 12-14 As shown, when working, the water receiving pipe 52 is connected to the external pressurized water body. The pressurized water passes through the fixed ring 51 and the rotating part 53 and is sprayed out by the bifurcated nozzle 54. The bifurcated nozzle 54 includes two vertical and inclined spray holes. The vertical spray hole sprays gas to reduce dust, and the recoil force of the water sprayed out from the inclined spray hole will drive the bifurcated nozzle 54 and the rotating part 53 to rotate. The collection filter 6 filters the sprayed water, and the guide block 7 guides the cleaning brush 58.
[0067] When the cleaning brush 58 rotates to the top of the collecting filter 6, the elastic force of the spring four 57 drives the pressure plate 56 and the cleaning brush 58 to press down, so that the cleaning brush 58 wipes and cleans the top of the collecting filter 6, thereby reducing the blockage of the collecting filter 6, improving the collection effect after spraying, and solving the problem of the inconvenience in collecting the dust and droplet combination after spraying, which easily causes the combination to accumulate on the inner wall of the ventilation duct.
[0068] Working principle: When using this device, first, Figures 1-14 As shown, the motor 41 is started, and the motor 41 drives the rotating shaft 42 and the fan blade part 43 to rotate. The fan blade part 43 draws air through the air inlet filter 2, and the rotating shaft 42 drives the fixed sleeve 416 to rotate. The arc sleeve 421 squeezes the arc plates 48 on both sides. When working, the water pipe 52 is connected to the external pressurized water body. The pressurized water body passes through the fixed ring 51 and the rotating part 53 and is sprayed out by the bifurcated nozzle 54. The bifurcated nozzle 54 includes two vertical and inclined nozzle holes. The vertical nozzle hole sprays the gas to reduce dust. The recoil of the water body sprayed out by the inclined nozzle hole drives the bifurcated nozzle 54 and the rotating part 53 to rotate, and the collection filter 6 filters the sprayed water body, and guides The cleaning brush 58 is guided toward block 7. When the cleaning brush 58 rotates to the top of the collecting filter 6, the elastic force of spring four 57 drives the pressure plate 56 and the cleaning brush 58 to press down, so that the cleaning brush 58 wipes and cleans the top of the collecting filter 6. When the motor 41 fails or ages, the speed of the rotating shaft 42 slows down, and the contact switches 413 on both sides are connected. At this time, the warning light 415 lights up as a warning, and when the speed of the rotating shaft 42 decreases, the elastic force of spring three 425 drives the rotating rod 424 to slide closer to the mounting sleeve 422, and the area of the air hole communicating with the annular groove 427 is reduced, so that the air intake of the duct body 1 is reduced.
