Abstract
Description
Technical Field
[0001] This invention belongs to the field of mine ventilation technology, specifically a coal mine underground ventilation regulation device. Background Technology
[0002] When mining coal, mine shafts are generally built to access the coal seam and facilitate mining operations. Existing coal mines are also classified into vertical shafts, inclined shafts, and horizontal adits. Regardless of the type of mine, ventilation and real-time monitoring of methane content are necessary to prevent excessive harm to the human body from dust or methane in the mine.
[0003] For example, the document with patent number CN114753878B discloses a ventilation device for detecting excessive gas levels in coal mines;
[0004] This invention discloses a coal mine gas over-limit detection and ventilation device, including a mine tunneling roadway, a monitoring host, ventilation ducts, a fan, a gas concentration sensor, an oxygen concentration sensor, a nitrogen concentration sensor, an electrical fault detection device, an oxygen generator, and a nitrogen generator. This invention achieves comprehensive monitoring of gas concentrations in various areas within the coal mine tunneling roadway. The monitoring host comprehensively evaluates the values of various environmental gases that cause gas over-limits within the tunneling roadway, breaking the traditional isolation of information on methane, carbon monoxide, and oxygen. By adding oxygen and nitrogen generators to the fan inlet, the monitoring host can directly control the fan inlet to reduce gas concentrations in various areas of the tunneling roadway. The addition of nitrogen, due to its inertness, also inhibits the oxidation reaction of oxygen and methane to produce carbon monoxide to some extent.
[0005] However, the existing ventilation systems only collect coal dust from inside the mine to the outside, and cannot effectively absorb coal dust in the mine. As a result, coal dust always exists in the mine or outside the mine shaft. Excessive coal dust can easily cause dust explosions and also damage the respiratory system of coal mine workers. Therefore, we provide a coal mine underground ventilation regulation device. Summary of the Invention

[0017] Preferably, the ventilation assembly includes a dual-axis motor and a fan duct fixedly mounted on the top of the water storage box. One end of the output shaft of the dual-axis motor is connected to a fan, and the other end of the output shaft of the dual-axis motor is connected to a gear. A bracket is fixedly mounted on the top of the water storage box, and a gear is connected to the internal bearing of the bracket.
[0018] Preferably, both gear one and gear two are located inside the bracket and mesh with each other, the outer side of gear two is fixedly connected to the spiral disk, and the number of teeth of gear one is less than the number of teeth of gear two.
[0019] Preferably, a water pipe is fixedly installed on the top of the water storage box.

[0022] Preferably, the water supply assembly further includes an extension rod that is driven to one side of the turbine;
[0023] The collection assembly also includes a turbine II and a metal threaded plate fixedly sleeved on the outer periphery of the extension rod.

A nut II is threadedly installed at the bottom of the water storage box.
[0024] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0025] This invention utilizes a combination of interception and ventilation components. The ventilation component draws air from the mine and water sprayed by the water supply component towards the side of the filter plate, causing the spiral disc to rotate. Coal dust contained in the air remains on the side of the filter plate. The rotating spiral disc concentrates the coal dust and water to the center of the filter plate and drops it into the storage box. When there is too much coal dust in the storage box, it will descend, and the coal dust will be washed away by the water. The weight of the storage box will also decrease. The connecting rod will also cause the guide ring to descend and scrape against the inner wall of the collection pipe. The mixture of coal dust and water adhering to the inner wall of the collection pipe will also fall into the storage box, thereby accelerating the descent speed of the storage box and improving the efficiency of the device. It also prevents blockage inside the collection pipe. The water supply component will also raise the bidirectional telescopic rod back to its initial state, enabling the device to repeatedly perform coal dust cleaning and collection.
[0026] This invention utilizes a combination of exhaust and water supply components. A dual-shaft motor drives a turbine via a chain to rotate. Water from the chamber containing the water supply component inside the water storage box is drawn into the water collection box and sprayed onto the side of the fan through a water pipe and water holes. One end of the bidirectional telescopic rod descends, while the other end, via a cover plate, raises the top of a rubber threaded plate. The increased pitch of the rubber threaded plate allows water to pass through it more quickly and be sprayed outwards, resulting in more water contact with the filter plate. Furthermore, the spiral disc can better rub against its side, achieving a better cleaning effect. Once the coal dust in the storage box is washed away by the water, a spring pushes the bidirectional telescopic rod back to its initial position, returning the device to its initial state and enabling reciprocating operation, further improving the device's efficiency.
[0027] This invention utilizes a combination of water supply and collection components. Turbine 1 drives an extension rod to rotate, while turbine 2 and the metal threaded plate rotate simultaneously. Turbine 2 guides water from the lower end of the partition towards the storage box, thereby flushing away coal dust inside the storage box. Turbine 2 also guides water containing coal dust to the opening at the horizontal end of water pipe 2. After the rotation of turbine 2, the coal dust eventually adheres to the side of spring 2. When there is too much coal dust, it will squeeze through the sealing plate and press against spring 2, falling onto the vertical side of water pipe 2. This further reduces the coal content of the water and also better flushes away the coal dust in the storage box. When the device is no longer working, opening nut 2 allows for cleaning of the coal dust inside water pipe 2. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0039] like Figures 1 to 9 As shown, the present invention provides a ventilation regulating device for underground coal mines, including a water storage box 1, wherein the interior of the water storage box 1 is divided into two independent chambers, and the interior of the two chambers is filled with water, and also includes;
[0040] The exhaust assembly 2 is installed on the top of the water storage box 1;
[0041] An interception component 3 is fixedly mounted on the top of the water storage box 1 and located on the side of the exhaust component 2;
[0042] The water supply component 4 is installed in one side chamber inside the water storage box 1. The water supply component 4 is used to draw water from the side chamber and spray it to the air outlet of the exhaust component 2.
[0043] Collection component 5 is installed in the other chamber inside the water storage box 1;
[0044] A plug 12 is installed on the top of the water storage box 1. The plug 12 is used to seal the side chamber where the water supply component 4 is installed.
[0045] Nut 13 is installed on the side of water storage box 1. Nut 13 is used to seal the other chamber where collection component 5 is located.
[0046] The interception component 3 includes a collection pipe 31 fixedly installed on the top of the water storage box 1 and connected to a side chamber where the collection component 5 is provided. A filter plate 32 is fixedly installed on the side of the collection pipe 31. A guide ring 35 is movably installed inside the collection pipe 31. A connecting rod 34 is fixedly installed at the bottom of the guide ring 35. A storage box 36 is movably sleeved on the outer periphery of the connecting rod 34. A filter plate is provided at the bottom of the storage box 36. A bidirectional telescopic rod 37 is connected to the ball shaft inside the water storage box 1. One side of the output end of the bidirectional telescopic rod 37 is hinged to the outer periphery of the connecting rod 34. A spiral disk 33 is drivenly connected to one side of the exhaust component 2. The water supply component 4 is also used to keep the bidirectional telescopic rod 37 always in an inclined state.
[0047] The exhaust assembly 2 is used to guide air to blow towards the side of the filter plate 32, and the exhaust assembly 2 is used to drive the spiral disk 33 to rotate.
[0048] A partition 15 is provided in the side chamber of the water storage box 1 where the collection component 5 is located. The partition 15 has a slot that matches the storage box 36. The storage box 36 is made of rubber. The top of the water storage box 1 has a storage groove 14 located at the bottom of the filter plate 32.
[0049] Using the above scheme: the device is first placed in the mine, and then the exhaust component 2 is turned on, which drives the air in the mine and the water sprayed by the water supply component 4 to flow to the side of the filter plate 32. The coal dust contained in the air is retained on the side of the filter plate 32. At the same time, the exhaust component 2 will also drive the spiral disk 33 to rotate. Since the spiral disk 33 is spiral, the mixture of coal dust and water attached to the side of the filter plate 32 will be concentrated to the middle part of the filter plate 32. Finally, the wind generated by the exhaust component 2 will blow it into the inside of the collection pipe 31.
[0050] The mixture is eventually guided by the connecting rod 34 and falls into the storage box 36. When there is too much coal powder inside the storage box 36, the storage box 36 and one side of the output end of the bidirectional telescopic rod 37 descend simultaneously and pass through the slot on the partition plate 15. The bottom of the partition plate 15 is filled with water, and most of the coal powder is pressed against the filter plate. When the storage box 36 cannot descend, the coal powder will also press the connecting rod 34 to descend, thus creating a gap between the storage box 36 and the filter plate. At this time, the coal powder inside the storage box 36 will be washed away by the water, and the weight of the storage box 36 will also decrease.
[0051] It should be noted that the bottom of the connecting rod 34 is equipped with a filter plate. This allows the connecting rod 34 and the storage box 36 to rise and return to their original positions when the water supply assembly 4 raises the bidirectional telescopic rod 37 to its initial state. The water inside the storage box 36 will flow out from the filter plate at the bottom of the storage box 36, thereby enabling the device to repeatedly perform coal powder cleaning and collection work.
[0052] During the descent of the connecting rod 34, it will also drive the guide ring 35 to descend, and force the guide ring 35 to scrape against the inner wall of the collection pipe 31. The mixture of coal powder and water adhering to the inner wall of the collection pipe 31 will also fall into the storage box 36, thereby accelerating the descent speed of the storage box 36. Furthermore, it improves the working efficiency of the device and avoids the blockage inside the collection pipe 31, which would prevent it from working properly.
[0053] Most of the water sprayed by the water supply component 4 will pass through the filter plate 32, with only a small portion remaining on the side of the filter plate 32. This allows the spiral disc 33 to better clean the coal dust on the side of the filter plate 32 during rotation. Similarly, the air generated by the exhaust component 2 will also pass through the side of the filter plate 32, thus dispersing the water and blowing it further. This further reduces the concentration of methane and the temperature of the air in the mine, thereby improving the safety of the mine shaft.
[0054] like Figures 1-6 As shown, the exhaust assembly 2 includes a dual-axis motor 21 and a fan duct 23 fixedly mounted on the top of the water storage box 1. One end of the output shaft of the dual-axis motor 21 is connected to a fan 22, and the other end of the output shaft of the dual-axis motor 21 is connected to a gear 24. A bracket 26 is fixedly mounted on the top of the water storage box 1, and a gear 25 is connected to the internal bearing of the bracket 26.
[0055] Both gear 24 and gear 25 are located inside the bracket 26 and mesh with each other. The outer side of gear 25 is fixedly connected to the spiral disk 33. The number of teeth of gear 24 is less than the number of teeth of gear 25.
[0056] The above scheme is adopted: the dual-shaft motor 21 is started first, which drives the fan 22 to rotate and generate wind power, thereby guiding the air in the mine through the filter plate 32. The gear 1 24 and gear 2 25 form a reduction gear set, which makes the wind power generated by the fan 22 greater, while the speed of the spiral disk 33 driven by gear 2 25 is reduced, thus avoiding the spiral disk 33 from rotating too fast and causing damage to the side of the filter plate 32. This further improves the working efficiency and service life of the device. Both gear 1 24 and gear 2 25 are located inside the support 26, which can prevent coal dust from affecting the meshing of gear 1 24 and gear 2 25.
[0057] like Figure 1 , Figure 2 , Figure 4 , Figures 6-9As shown, a water pipe 41 is fixedly installed on the top of the water storage box 1. The top of the water pipe 41 is circular and has several water holes 43 opened at equal angles around its outer periphery. One end of the output shaft of the dual-axis motor 21 is connected to a turbine 48 via a chain 42. A water collection box 47 is fixedly installed in one side chamber of the water supply component 4 inside the water storage box 1. A rubber threaded plate 45 is elastically connected inside the water pipe 41 via a spring 44. A cover plate 46 is movably snapped onto the outer periphery of the water pipe 41. The cover plate 46 is fixedly connected to the bottom of the spring 44.
[0058] The turbine 48 is located inside the water collection box 47. The water collection box 47 is connected to a side chamber where the water supply component 4 is provided. The interior of the water collection box 47 is connected to the interior of the water pipe 41. The output end of the bidirectional telescopic rod 37 is hinged to the cover plate 46.
[0059] Using the above scheme: the dual-shaft motor 21 drives the turbine 48 to rotate through the chain 42, thereby drawing water from the side chamber of the water storage box 1 where the water supply component 4 is installed to the inside of the water collection box 47, and finally spraying it to the side of the fan 22 through the water pipe 41 and the water hole 43.
[0060] When the storage box 36 is pressed down by the weight of the coal powder inside, one end of the bidirectional telescopic rod 37 descends simultaneously, while the other end drives the top of the rubber threaded plate 45 to rise through the cover plate 46. The pitch of the rubber threaded plate 45 increases, allowing water to pass through the rubber threaded plate 45 more quickly and be sprayed outwards. The filter plate 32 comes into contact with more water, and furthermore, the spiral disc 33 can better rub against the side of the spiral disc 33, thus achieving a better cleaning effect. After the coal powder in the storage box 36 is washed away by the water, the spring 44 pushes the bidirectional telescopic rod 37 back to its initial position. At this time, the device returns to its initial state and can perform reciprocating work, further improving the working efficiency of the device.
[0061] like Figure 5 , Figure 7 and Figure 9 As shown, the collection component 5 includes a water pipe 51 fixedly installed in one side chamber of the water storage box 1. The water pipe 51 is in an "L" shape rotated 180 degrees. The interior of the horizontal end of the water pipe 51 is elastically connected to a sealing plate 55 by a spring 54.
[0062] The water supply assembly 4 also includes an extension rod 49 that is connected to the side of the turbine 48 via a transmission.
[0063] The collection assembly 5 also includes a turbine 52 and a metal threaded plate 53 fixedly sleeved on the outer periphery of the extension rod 49. The metal threaded plate 53 is located inside the horizontal end of the water pipe 51 and the outer side of the metal threaded plate 53 is in close contact with the side of the sealing plate 55. The bottom of the water storage box 1 is threaded with a nut 56.
[0064] The above scheme is adopted: Turbine 1 48 drives the extension rod 49 to rotate, Turbine 2 52 and metal threaded plate 53 rotate simultaneously. Turbine 2 52 guides the water at the lower end of the partition plate 15 to impact the storage box 36. When the storage box 36 is located below the storage box 36 and can no longer be moved, there is a gap between the filter plate at the bottom of the connecting rod 34 and the bottom of the storage box 36, so that the water flow generated by Turbine 2 52 can wash away the coal powder inside the storage box 36. Turbine 2 52 also guides the water containing coal powder to the opening at the horizontal end of the water pipe 2 51. After the rotation of Turbine 2 52, the coal powder finally sticks to the side of the spring 2 54. When there is too much coal powder, it will squeeze through the sealing plate 55 to squeeze the spring 2 54 and fall into the interior of the vertical end of the water pipe 2 51. This further reduces the coal content of the water. Similarly, it can better wash away the coal powder in the storage box 36. When the device is no longer working, nut 2 56 can be opened to clean the coal powder inside the water pipe 2 51.
[0065] Working principle and usage process of this invention:
[0066] The device is first placed in the mine, and then the dual-axis motor 21 is turned on to drive the fan 22 to rotate and generate wind, thereby guiding the air in the mine through the filter plate 32. The dual-axis motor 21 drives the turbine 48 to rotate through the chain 42, thereby drawing water from the side chamber of the water storage box 1 which is equipped with the water supply component 4 to the inside of the water collection box 47, and finally spraying it to the side of the fan 22 through the water pipe 41 and the water hole 43.
[0067] The coal dust contained in the air is retained on the side of the filter plate 32. The dual-shaft motor 21 drives the spiral disk 33 to rotate through gear 1 24 and gear 2 25. The mixture of coal dust and water adhering to the side of the filter plate 32 will be concentrated in the middle part of the filter plate 32, and finally blown into the inside of the collection pipe 31 by the wind generated by the exhaust assembly 2.
[0068] The mixture is eventually guided by the connecting rod 34 and falls into the storage box 36. When there is too much coal powder inside the storage box 36, the storage box 36 and one side of the output end of the bidirectional telescopic rod 37 descend simultaneously and pass through the slot on the partition plate 15. Most of the coal powder is pressed onto the filter plate. When the storage box 36 cannot descend, the coal powder will also press the connecting rod 34 to descend, thus creating a gap between the storage box 36 and the filter plate. At this time, the coal powder inside the storage box 36 will be washed away by water, and the weight of the storage box 36 will also decrease.
[0069] During the descent of the connecting rod 34, it will also drive the guide ring 35 to descend, and force the guide ring 35 to scrape against the inner wall of the collection pipe 31. The mixture of coal powder and water adhering to the inner wall of the collection pipe 31 will also fall into the interior of the storage box 36.
[0070] One end of the bidirectional telescopic rod 37 descends simultaneously, while the other end drives the top of the rubber threaded plate 45 to rise through the cover plate 46. The pitch of the rubber threaded plate 45 increases, allowing water to pass through the rubber threaded plate 45 more quickly and be sprayed to the outside, and the filter plate 32 comes into contact with more water.
[0071] Turbine 1 48 drives extension rod 49 to rotate, turbine 2 52 and metal threaded plate 53 rotate simultaneously. Turbine 2 52 guides the water at the lower end of partition 15 to impact storage box 36. When storage box 36 is located below storage box 36 and can no longer be moved, there is a gap between the filter plate at the bottom of connecting rod 34 and the bottom of storage box 36, so that the water flow generated by turbine 2 52 can wash away the coal powder inside storage box 36. Turbine 2 52 also guides the water containing coal powder to the opening at the horizontal end of water pipe 2 51. After the rotation of turbine 2 52, the coal powder finally sticks to the side of spring 2 54. When there is too much coal powder, it will squeeze through the sealing plate 55 to squeeze spring 2 54 and fall into the interior of the vertical end of water pipe 2 51.
