Description

[0001] The present invention relates to the technical field of mine auxiliary equipment, in particular to a mine gas tunnel safety ventilation device. Background Art

[0002] During the construction and use of mines, a large amount of gas may be excavated. In order to avoid explosions caused by excessive gas concentrations deep in the mine, ventilation devices need to be installed in the mine tunnels to ensure that the gas concentration in the mine tunnels is kept low, while also ensuring that the air in the mine tunnels can be circulated.

[0003] At present, ventilation circulation treatment in mine tunnels is usually carried out by using fans to suck and blow air. However, due to the flammable and explosive characteristics of gas, when the air humidity in the mine tunnel and its surroundings is low and the weather is hot and dry, even if ventilation is continued, it is easy to cause gas explosions in the mine tunnel. The ventilation device can only perform ventilation circulation treatment.

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.

[0029] In order to solve the technical problem that when the air humidity in the mine tunnel and the surrounding area is low and the weather is hot and dry, even if ventilation is continued, it is easy to cause gas explosion in the mine tunnel, which is highly dangerous, such as Figures 1-4 and Figure 7-10 As shown, the following preferred technical solutions are provided:

[0030] A mine gas tunnel safety ventilation device includes a mounting shell 1, a fan 2 is fixedly installed through the middle upper end of the mounting shell 1, an air humidity sensor 3 is fixedly installed in the inner cavity of the fan 2, a water tank 4 is fixedly installed on the top surface of the mounting shell 1, a T-shaped sprinkler column 5 is movably installed on the lower middle outer wall of one side of the mounting shell 1, a raised frame 6 is fixedly installed on the outer peripheral wall of one side of the mounting shell 1, and an inner baffle 7 is fixedly installed on the inner outer wall of one side of the raised frame 6, a pressure water suction box 8 is fixedly installed at one end of the top surface of the water tank 4, and the pressure water suction box 8 is connected to the water tank 4, and a ventilation duct 9 is connected to the middle outer wall of the upper end of the other side of the mounting shell 1. After the mounting shell 1 is fixedly installed at the external opening of the mine tunnel, the mine tunnel can be ventilated by starting the fan 2.

[0031] A circular mounting hole 11 is provided at the middle of the upper end of the mounting shell 1, an insertion groove 12 is provided on the outer wall of the middle part of the lower end of one side of the mounting shell 1, a top through hole 13 is provided at the middle of the top surface of the mounting shell 1, and a concave inner groove 14 is provided on the outer periphery of the inner cavity of one end of the mounting shell 1, and the upper end of the concave inner groove 14 is connected to the top through hole 13, and the lower end of the concave inner groove 14 is connected to the insertion groove 12 through an inclined through hole 15, an arcuate annular groove 121 is provided at the middle of the inner cavity of the insertion groove 12, and the inner wall of the inner cavity of the insertion groove 12 is provided. A sealing sleeve 122 is fixedly mounted on the upper portion, and a sealing ring 123 is fixedly mounted on the outer peripheral wall of one side of the sealing sleeve 122, and the inner end portion of the T-shaped sprinkler column 5 is sealedly connected to the sealing sleeve 122 through the sealing ring 123. This arrangement enables the T-shaped sprinkler column 5 to rotate quickly while also achieving a sealed connection between the T-shaped sprinkler column 5 and the sealing sleeve 122. When the water storage tank 4 is filled with water, under the action of gravity, water will enter the concave inner groove 14 through the top through hole 13 and fill the T-shaped sprinkler column 5 through the inclined through hole 15.

[0032] The air humidity sensor 3 includes a support column 31 and a sensor body 32 fixedly mounted on the upper end of the support column 31 , and the support column 31 is fixedly mounted on the inner wall on the other side of the inner cavity of the circular mounting hole 11 .

[0033] A threaded water inlet 41 is installed on the top of the water tank 4, and a threaded cover 42 is installed on the threaded water inlet 41 through a threaded seal. By screwing open the threaded cover 42, water can be filled into the water tank 4 through the threaded water inlet 41. The two ends of the inner bottom surface of the raised frame 6 are respectively arranged with inclined surfaces, and an entrance bottom hole 61 is provided at the middle part of the inner bottom surface of the raised frame 6. A water suction pipe 62 is sealed and fixedly installed at the middle part of the bottom surface of the raised frame 6, and the upper end part of the water suction pipe 62 is connected and installed on the upper outer wall of the pressure water suction box 8; a negative pressure pipe 81 is connected and fixedly installed on the outer wall of the other side of the upper end of the pressure water suction box 8, and the lower end part of the negative pressure pipe 81 is connected and installed on the outer wall of the mounting shell 1, and the negative pressure pipe 81 is connected and installed on the inner cavity of the fan housing 21.

[0034] The T-shaped sprinkler column 5 includes a rotating drum 51 and a sprinkler plate 53 fixedly mounted on one side of the rotating drum 51. A plurality of connecting balls 52 are evenly mounted on the outer peripheral wall of the middle portion of the rotating drum 51, and the connecting balls 52 are respectively arranged in the arc-shaped annular groove 121. A plurality of elastic blocking plates 54 are evenly mounted on the outer peripheral wall of the sprinkler plate 53. An annular tooth groove 511 is provided on the outer peripheral wall of one side end of the rotating drum 51, and the lower end of the transmission belt 25 is engaged and sleeved in the annular tooth groove 511. The inner middle outer wall of the sprinkler plate 53 is provided with a A T-shaped water inlet groove 531 is provided, and a number of T-shaped water outlet holes 532 are evenly arranged on the outer wall of the sprinkler plate 53. The elastic sealing plate 54 includes an inclined plate 541 and a bottom protrusion 542 fixedly installed in the middle of the bottom surface of the inclined plate 541. A sealing gasket 543 is fixedly installed on the bottom surface of the bottom protrusion 542. One end of the inclined plate 541 is provided with a raised upper end opening of the T-shaped water outlet hole 532, and both sides of the other end of the inclined plate 541 are elastically mounted in the inner cavity of the T-shaped water outlet hole 532 through torsion springs 544.

[0035] Specifically, through the setting of the air humidity sensor 3, when the air humidity of the air inhaled by the fan 2 is less than a preset value, the air humidity sensor 3 can send an electrical signal to the fan 2, so that the fan 2 can drive the T-shaped sprinkler column 5 to rotate while sucking air. At this time, the upper end opening of the T-shaped water outlet 532 is raised by one end of the elastic sealing plate 54, so that when the sprinkler disc 53 rotates rapidly, it will drive the elastic sealing plate 54 to rotate clockwise through centrifugal force and wind resistance, so that the sealing gasket 543 leaves the T-shaped water outlet 532. At this time, water will splash out from the T-shaped water outlet 532 under the action of centrifugal force, and the water splashed to the fan 2 will be sucked into the fan 2, thereby ensuring the humidity in the mine tunnel. The structure is cleverly set up, and one machine has multiple uses. The humidification effect is achieved by utilizing the wind power of the fan 2, which not only has a good effect, but also prevents gas explosions and improves the safety of the mine tunnel.

[0036] Furthermore, the water thrown out by the sprinkler plate 53 can splash onto the raised frame 6 and be blocked by the inner baffle 7 to prevent water from leaking from the raised frame 6. The collected water will flow into the bottom hole 61 and into the lower end inner cavity of the water suction pipe 62. At this time, the inner cavity of the pressure water suction box 8 is in a negative pressure state through the setting of the negative pressure pipe 81, so that water can be continuously drawn into the pressure water suction box 8 from the water suction pipe 62, and finally flow into the water storage tank 4 for collection. While saving water, the fan 2 can also be used to automatically replenish the collected water to the water storage tank 4. The whole process is automatic and convenient to use.

[0037] In order to solve the technical problem of how to drive the T-shaped sprinkler column 5 to rotate quickly by the fan 2 to save the use and manufacturing costs, as shown in FIG. Figure 3 、 Figure 5 and Figure 6 As shown, the following preferred technical solutions are provided:

[0038] The fan 2 includes a fan housing 21 and a mounting frame 22 fixedly mounted in the middle of the inner cavity of the fan housing 21. A drive motor 23 is embedded and fixedly mounted in the inner cavity of the mounting frame 22. A fan 24 is movably mounted on the outer wall of the middle part of one side of the mounting frame 22, and the output end of the drive motor 23 is fixedly mounted on the fan 24. The output end of the drive motor 23 is connected to the T-shaped sprinkler column 5 through a transmission belt 25. An H-shaped connecting shaft 231 is fixedly mounted on the output end of the drive motor 23, and a gear sleeve 232 is movably sleeved on the middle periphery of the H-shaped connecting shaft 231. An electromagnet 233 is fixedly mounted in the inner cavity of the middle part of the H-shaped connecting shaft 231. A magnetic clamping block 234 is also installed in the middle inner cavity of the H-shaped connecting shaft 231. The upper end of the transmission belt 25 is engaged with the outer periphery of the gear sleeve 232. A clamping groove 2321 is provided on the inner inner wall of the gear sleeve 232. An receiving groove 2311 is provided on the outer peripheral wall of the middle part of the inner cavity of the H-shaped connecting shaft 231, and the receiving groove 2311 is provided on the outer side of the electromagnet 233. The magnetic clamping block 234 includes a metal clamping block 2341 and a reset spring 2342 installed at the bottom of the metal clamping block 2341, and the metal clamping block 2341 is elastically slidably installed in the receiving groove 2311 through the reset spring 2342.

[0039] Specifically, when the fan 2 needs to drive the T-shaped sprinkler column 5 to rotate, the electromagnet 233 will be activated, thereby generating a repulsive force on the metal clamping block 2341, so that the metal clamping block 2341 is clamped into the clamping groove 2321. When the H-shaped connecting shaft 231 rotates, it can simultaneously drive the gear sleeve 232 to rotate. Driven by the transmission belt 25, the T-shaped sprinkler column 5 can be driven to rotate. When watering is not needed, the electromagnet 233 will be turned off. Under the elastic force of the reset spring 2342, the metal clamping block 2341 will automatically reset. The whole process is automatic, one machine has multiple uses, and saves the cost of driving the T-shaped sprinkler column 5 to rotate.
