Description

Technical Field

[0001] The invention belongs to the technical field of mine ventilation, in particular to an underground ventilation regulating device for a coal mine. Background Art

[0002] When mining coal, a mine is usually built to enter the coal seam, so as to better carry out the mining work. In the existing coal mines, there are vertical shafts, inclined shafts and horizontal tunnels. However, no matter what kind of mine, the interior needs to be ventilated and the gas content needs to be detected in real time to avoid excessive harm to the human body caused by dust or gas in the mine.

[0003] For example, the document with patent number: CN114753878B discloses a ventilation device for detecting excessive gas in coal mines;

[0004] The present invention discloses a ventilation device for detecting excessive gas in a coal mine, comprising a mine excavation tunnel, a monitoring host, a ventilation duct, a ventilator, a gas concentration sensor, an oxygen concentration sensor, a nitrogen concentration sensor, an electrical appliance fault detection device, an oxygen production device, and a nitrogen production device. The present invention realizes all-round monitoring of the gas concentration in each area of ​​the mine excavation tunnel in the coal mine, and comprehensively evaluates the values ​​of various environmental gases in the excavation tunnel that cause excessive gas through the monitoring host, breaking the phenomenon of traditional methane, carbon monoxide and oxygen information islands; by adding oxygen and nitrogen production equipment to the pressure-in blower end, it is convenient to directly reduce the gas concentration in each area of ​​the mine excavation tunnel by controlling the blower air inlet end through the monitoring host, and the addition of nitrogen, due to its inertness, also inhibits the reaction process of the oxidation reaction of oxygen and methane to produce carbon monoxide to a certain extent.

[0005] However, the ventilation system provided by the prior art only collects the coal powder inside the mine to the outside of the mine, and cannot effectively absorb the coal powder in the mine, which results in the coal powder always existing in the mine or outside the mine. Excessive coal powder not only easily causes dust explosions, but also causes damage to the respiratory system of workers in the coal mine. For this reason, we provide a ventilation and adjustment device for underground coal mines. Summary of the invention

The bottom thread of the water storage box is threaded with a nut 2.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention cooperates with structures such as an interception component and an exhaust component. The exhaust component drives the air in the mine and the water sprayed by the water supply component to flow to the side of the filter plate, and drives the spiral disk to rotate, while the coal powder contained in the air is retained on the side of the filter plate. The spiral disk rotates to concentrate the coal powder and water to the middle of the filter plate and drops into the interior of the storage box. When there is too much coal powder in the storage box, it will fall and be washed away by water. The weight of the storage box will also decrease. The connecting rod will also drive the guide ring to descend and scratch the inner wall of the collection pipe. The mixture of coal powder and water adhered to the inner wall of the collection pipe will also fall into the interior of the storage box, thereby accelerating the descent speed of the storage box, thereby improving the working efficiency of the device and avoiding blockage inside the collection pipe. The water supply component will also lift the two-way telescopic rod to the initial state again, so that the device can reciprocate to clean and collect coal powder.

[0026] The present invention cooperates with structures such as an exhaust component and a water supply component. A dual-axis motor drives a turbine to rotate through a chain. Water in a chamber on one side of a water supply component provided inside a water storage box is drawn into the water collection box and sprayed to the side of the fan through a water pipe and a water hole. One end of the two-way telescopic rod descends, and the other end thereof drives the top of the rubber threaded sheet to rise through a cover plate. The pitch of the rubber threaded sheet increases, so that water can pass through the rubber threaded sheet more quickly and spray to the outside. The filter plate contacts more water. Furthermore, the spiral disk can better scrape the side of the spiral disk, thereby achieving a better cleaning effect. When the coal powder in the storage box is washed away by water, a spring pushes the two-way telescopic rod back to its original position. At this time, the device is in its initial state again and can perform reciprocating work, thereby further improving the working efficiency of the device.

[0027] The present invention cooperates with structures such as a water supply component and a collection component. Turbine 1 drives the extension rod to rotate, and turbine 2 and the metal threaded sheet rotate at the same time. Turbine 2 guides the water at the lower end of the partition to impact the storage box, thereby flushing out the coal powder inside the storage box, and turbine 2 also guides the water containing coal powder to flow to the opening at the horizontal end of water pipe 2. After the rotation of turbine 2, the coal powder eventually adheres to the side of spring 2. When there is too much coal powder, it will squeeze through the closing plate to squeeze spring 2 and fall on the vertical side of water pipe 2. Further, the coal content of the water can be reduced. Similarly, the coal powder in the storage box can be better flushed. When the device no longer works, nut 2 is opened to clean the coal powder inside water pipe 2. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0039] like Figures 1 to 9 As shown, the present invention provides a ventilation and regulating device for underground coal mines, comprising a water storage box 1, wherein the interior of the water storage box 1 is divided into two independent left and right chambers and the interiors of the two chambers are filled with water, and further comprising;

[0040] An exhaust assembly 2 is arranged on the top of the water storage box 1;

[0041] An interception component 3 fixedly mounted on the top of the water storage box 1 and located on the side of the exhaust component 2;

[0042] A water supply component 4 is disposed in a side chamber inside the water storage box 1, and the water supply component 4 is used to extract water in the side chamber and spray it to the air outlet of the exhaust component 2;

[0043] A collecting assembly 5 installed in the other side chamber of the water storage box 1;

[0044] A plug 12 is installed on the top of the water storage box 1, and the plug 12 is used to block the side chamber where the water supply component 4 is set;

[0045] A nut 13 is installed on the side of the water storage box 1, and the nut 13 is used to block the other side chamber where the collecting assembly 5 is arranged;

[0046] The interception assembly 3 includes a collection pipe 31 fixedly mounted on the top of the water storage box 1 and connected to a side chamber provided with the collection assembly 5, a filter plate 32 is fixedly mounted on the side of the collection pipe 31, a guide ring 35 is movably mounted inside the collection pipe 31, a connecting rod 34 is fixedly mounted 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 two-way telescopic rod 37 is connected to the internal ball shaft of the water storage box 1, one side of the output end of the two-way telescopic rod 37 is hinged to the outer periphery of the connecting rod 34, a spiral disk 33 is transmission-connected to one side of the exhaust assembly 2, and the water supply assembly 4 is also used to keep the two-way telescopic rod 37 always in an inclined state;

[0047] The exhaust assembly 2 is used to guide the air to blow toward 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 a side chamber of the water storage box 1 where the collecting assembly 5 is provided. The partition 15 is provided with a notch adapted to the storage box 36. The storage box 36 is made of rubber. A storage groove 14 is provided on the top of the water storage box 1 and is located at the bottom of the filter plate 32.

[0049] The above scheme is adopted: the device is placed in the mine first, and then the exhaust assembly 2 is turned on to drive the air in the mine and the water sprayed by the water supply assembly 4 to flow to the side of the filter plate 32, and the coal powder contained in the air is retained on the side of the filter plate 32. The exhaust assembly 2 will also drive the spiral disk 33 to rotate. Since the spiral disk 33 is spiral, the mixture of coal powder and water attached to the side of the filter plate 32 will be concentrated to the middle part of the filter plate 32, and finally the wind generated by the exhaust assembly 2 is blown to the inside of the collection pipe 31;

[0050] The mixture finally falls into the storage box 36 under the guidance of the connecting rod 34. When there is too much coal powder in the storage box 36, the storage box 36 and one side of the output end of the two-way telescopic rod 37 will drop at the same time and pass through the notch on the partition 15. The bottom of the partition 15 is filled with water. Most of the coal powder is pressed on the filter plate. When the storage box 36 cannot drop, the coal powder will also press the connecting rod 34 to drop, so that there is a gap between the storage box 36 and the filter plate. At this time, the coal powder in 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 a filter plate is provided at the bottom of the connecting rod 34, so that when the water supply assembly 4 lifts the two-way telescopic rod 37 to the initial state, the connecting rod 34 and the storage box 36 rise and return to the initial position, and the water inside the storage box 36 will flow out from the filter plate at the bottom of the storage box 36, so that the device can reciprocate to clean and collect coal powder;

[0052] When the connecting rod 34 descends, it also drives the guide ring 35 to descend, and forces the guide ring 35 to scrape the inner wall of the collecting pipe 31, and the mixture of coal powder and water adhering to the inner wall of the collecting pipe 31 will also fall into the storage box 36, thereby accelerating the descending speed of the storage box 36, further improving the working efficiency of the device, and avoiding the clogging of the collecting pipe 31, which causes the abnormal working state;

[0053] Most of the water sprayed by the water supply component 4 will pass through the filter plate 32, and only a small part will remain on the side of the filter plate 32. This allows the spiral disk 33 to better clean the coal powder on the side of the filter plate 32 during rotation. Similarly, the wind generated by the exhaust component 2 will also pass through the side of the filter plate 32, thereby breaking up the water and blowing it farther, further reducing the gas concentration in the mine and the temperature of the air, thereby improving the safety of the mine seats.

[0054] like Figure 1-Figure 6 As shown, the exhaust assembly 2 includes a double-axis motor 21 and a wind tube 23 fixedly mounted on the top of the water storage box 1, one end of the output shaft of the double-axis motor 21 is transmission-connected to the fan 22, the other end of the output shaft of the double-axis motor 21 is transmission-connected to the gear 1 24, and a bracket 26 is fixedly mounted on the top of the water storage box 1, and the internal bearing of the bracket 26 is connected to the gear 2 25.

[0055] The gear 1 24 and the gear 2 25 are both located inside the bracket 26 and mesh with each other. The outer side of the gear 2 25 is fixedly connected to the spiral disk 33 . The number of teeth of the gear 1 24 is smaller than that of the gear 2 25 .

[0056] The above scheme is adopted: the dual-axis motor 21 is started first to drive the fan 22 to rotate and generate wind force, so that the air in the mine can be guided through the filter plate 32, and the gear 1 24 and the gear 2 25 form a reduction gear set, which makes the wind force generated by the fan 22 larger, and the speed at which the spiral disk 33 rotates driven by the gear 2 25 is reduced, thereby avoiding the spiral disk 33 from rotating too fast and causing damage to the side of the filter plate 32, further improving the working efficiency and service life of the device, and the gear 1 24 and the gear 2 25 are both located inside the bracket 26, which can prevent the coal powder from affecting the meshing of the gear 1 24 and the gear 2 25.

[0057] like Figure 1 , Figure 2 , Figure 4 , Figure 6-Figure 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 a plurality of water holes 43 are opened at equal angles in the outer circumference, one end of the output shaft of the dual-axis motor 21 is connected to a turbine 48 through a chain 42, a side chamber of a water supply component 4 is provided inside the water storage box 1, and a water collecting box 47 is fixedly installed in the chamber, the inside of the water pipe 41 is elastically connected to a rubber threaded piece 45 through a spring 44, and a cover plate 46 is movably clamped on the outer periphery of the water pipe 41, and the cover plate 46 is fixedly connected to the bottom of the spring 44.

[0058] The turbine 48 is located inside the water collecting box 47, the water collecting box 47 is connected to a side chamber provided with a water supply assembly 4, the interior of the water collecting box 47 is connected to the interior of the water pipe 41, and the output end of the bidirectional telescopic rod 37 is hinged to the cover plate 46.

[0059] The above scheme is adopted: the dual-axis motor 21 drives the turbine 48 to rotate through the chain 42, so that the water in the chamber on one side of the water storage box 1 where the water supply component 4 is arranged is drawn into the inside of the water collection box 47, and finally sprayed 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 it, one end of the two-way telescopic rod 37 descends at the same time, and the other end drives the top of the rubber threaded sheet 45 to rise through the cover plate 46. The pitch of the rubber threaded sheet 45 increases, so that water can pass through the rubber threaded sheet 45 more quickly and spray to the outside, and the filter plate 32 is in contact with more water. Furthermore, the spiral disk 33 can better scrape the side of the spiral disk 33, thereby achieving a better cleaning effect. When the coal powder in the storage box 36 is washed away by water, the spring 44 pushes the two-way telescopic rod 37 back to its original position. At this time, the device is in its initial state again and can perform reciprocating work, which further improves the working efficiency of the device.

[0061] like Figure 5 , Figure 7 and Fig. 9 As shown, the collecting assembly 5 includes a water pipe 51 fixedly installed in a side chamber of the water storage box 1 where the collecting assembly 5 is provided. The water pipe 51 is in an "L" shape rotated one hundred and eighty degrees, and the interior of the horizontal end of the water pipe 51 is elastically connected to a closing plate 55 through a spring 54.

[0062] The water supply assembly 4 also includes an extension rod 49 which is transmission-connected to the side of the turbine 1 48;

[0063] The collecting assembly 5 also includes a turbine 2 52 and a metal threaded sheet 53 fixedly mounted on the outer periphery of the extension rod 49. The metal threaded sheet 53 is located inside the horizontal end of the water pipe 2 51 and the outer side of the metal threaded sheet 53 is tightly attached to the side of the closing plate 55. The bottom thread of the water storage box 1 is threadedly installed with a nut 2 56.

[0064] The above scheme is adopted: turbine 1 48 drives the extension rod 49 to rotate, turbine 2 52 and metal threaded sheet 53 rotate at the same time, turbine 2 52 guides the water at the lower end of the partition 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 flush out the coal powder inside the storage box 36, and turbine 2 52 will also guide the water containing coal powder to flow to the opening at the horizontal end of water pipe 2 51. After the rotation of turbine 2 52, the coal powder is finally adhered to the side of spring 2 54. When there is too much coal powder, it will squeeze through the closing plate 55 to squeeze the spring 2 54 and fall into the inside of the vertical end of water pipe 2 51, further, the coal content of the water can be reduced. Similarly, the coal powder in the storage box 36 can be better flushed. When the device is no longer working, nut 2 56 is opened to clean the coal powder inside water pipe 2 51.

[0065] The working principle and use process of the present invention:

[0066] The device is preferably placed in a mine, and then the dual-axis motor 21 is turned on to drive the fan 22 to rotate and generate wind, so that the air in the mine can be guided through the filter plate 32. The dual-axis motor 21 drives the turbine 48 to rotate through the chain 42, so that the water in the chamber on one side of the water storage box 1 where the water supply component 4 is arranged is drawn into the inside of the water collection box 47, and finally sprayed to the side of the fan 22 through the water pipe 41 and the water hole 43;

[0067] The coal powder contained in the air is retained on the side of the filter plate 32. The dual-axis motor 21 drives the spiral disk 33 to rotate through the gear 1 24 and the gear 2 25. The mixture of coal powder and water attached to the side of the filter plate 32 will be concentrated to the middle part of the filter plate 32, and finally blown to the inside of the collection pipe 31 by the wind force generated by the exhaust assembly 2.

[0068] The mixture finally falls into the storage box 36 under the guidance of the connecting rod 34. When there is too much coal powder in the storage box 36, the storage box 36 and one side of the output end of the two-way telescopic rod 37 are simultaneously lowered and penetrate the notch on the partition 15. Most of the coal powder is pressed on the filter plate. When the storage box 36 cannot be lowered, the coal powder will also press the connecting rod 34 to lower, so that there is a gap between the storage box 36 and the filter plate. At this time, the coal powder in the storage box 36 will be washed away by water, and the weight of the storage box 36 will also decrease.

[0069] When the connecting rod 34 descends, it also drives the guide ring 35 to descend, and forces the guide ring 35 to scrape the inner wall of the collecting pipe 31, and the mixture of coal powder and water adhering to the inner wall of the collecting pipe 31 will also fall into the interior of the storage box 36;

[0070] One end of the two-way telescopic rod 37 descends at the same time, and the other end thereof drives the top of the rubber threaded sheet 45 to rise through the cover plate 46, and the pitch of the rubber threaded sheet 45 increases, so that water can pass through the rubber threaded sheet 45 more quickly and spray to the outside, and the filter plate 32 contacts more water;

[0071] Turbine 1 48 drives the extension rod 49 to rotate, and turbine 2 52 and the metal threaded sheet 53 rotate at the same time. Turbine 2 52 guides the water at the lower end of the partition 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 flush out the coal powder inside the storage box 36, and turbine 2 52 will also guide 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 will eventually adhere to the side of spring 2 54. When there is too much coal powder, it will squeeze through the closing plate 55 to squeeze spring 2 54 and fall into the inside of the vertical end of water pipe 2 51.
