Specific embodiments

[0028] Please refer to Figures 1 to 6 , in the embodiment of the present invention, a safety ventilation system for auxiliary haulage gate based on progressive mining includes a ventilation module.

[0029] The filter assembly 3 includes a filter seat 31, a rotating seat 32, a rotating rod 33, and a filter net 34. Among them, the filter seat 31 is fixedly arranged at the air inlet 21.

A filter net 34 is fixedly arranged between the plurality of rotating rods 33.

[0030] During implementation, the monitoring module monitors the oxygen content, toxic gas concentration, air humidity and coal powder content inside the tunnel in real time, and then controls the arc baffle 7 through the control module to open the corresponding air outlet 11 and air inlet 21 to perform local ventilation replacement on the tunnel, replace the toxic gas in the tunnel and introduce fresh air, and adjust the atomization intensity of the atomization mechanism 5 through the adjustment mechanism 6 during the ventilation process, so as to remove dust from the air in the tunnel and keep the air at a certain humidity, thereby improving the air quality in the tunnel, and in the process of leading the toxic gas out of the tunnel, the coal powder in the air is filtered through the filter component 3 to prevent the coal powder from clogging the ventilation equipment, and the filter component 3 is cleaned by the cleaning mechanism 4 to prevent the filter net 34 from being blocked due to long-term use, thereby realizing automatic replacement of the air in the tunnel, thereby ensuring the safety of the miners.

[0031] In this embodiment, Figure 4 An axial flow fan 35 is rotatably arranged on the support shaft 111, a sleeve shaft 1 is arranged on the axial flow fan 35, a sleeve shaft 2 is arranged on the rotating seat 32, and the sleeve shaft 1 and the sleeve shaft 2 are connected through a pulley 36.

Subsequently, when the rotating rod 33 rotates to the bottom of the cleaning plate 41, the rotating rod 33 is deflected under the action of the arc block 43, and then the arc block 43 is separated from the arc block 43 and knocks on the cleaning plate 41 under the action of the spring 1 to generate vibration, so that the coal powder on the filter screen 34 is shaken off into the collecting tank 42, so as to prevent the filter screen 34 from being blocked due to long-term use and affecting the filtering effect.

[0034] In this embodiment, Figure 5, the atomizing mechanism 5 includes an atomizing seat 51, a piston rod 52, and a water supply chamber 53. Among them, a second support shaft 211 is fixedly arranged on the air outlet 11, the atomizing seat 51 is fixedly arranged on the second support shaft 211, a hydraulic chamber 54 is formed inside the atomizing seat 51, a partition plate 55 is fixedly arranged in the hydraulic chamber 54, the piston rod 52 seals and slides along the inner side of the partition plate 55, a plurality of liquid spraying ports 541 are circumferentially arranged at one end of the hydraulic chamber 54 away from the second support shaft 211, a plurality of liquid supply ports 542 are circumferentially arranged at one end of the hydraulic chamber 54 close to the second support shaft 211, a water supply chamber 53 is arranged outside the liquid supply port 542, and the water supply chamber 53 is communicated with a water supply tank fixedly arranged on the top of the air guide pipe 2 through a water supply pipe.

[0036] and the clamping plate 563 in the liquid spraying port 541 is located inside the hydraulic chamber 54, and the clamping plate 563 in the liquid supply port 542 is located outside the hydraulic chamber 54.

[0037] During implementation, when the piston rod 52 slides towards the liquid spraying port 541, the sealing plug 56 in the liquid supply port 542 is pressed against the liquid supply port 542 to seal a plurality of the liquid supply ports 542, and the sealing plug 56 in the liquid spraying port 541 is pressed to disengage from the liquid spraying port 541, so that the liquid spraying port 541 is opened, and then the liquid in the hydraulic chamber 54 is sprayed out and forms water mist under the wind pressure generated by the second axial flow fan 212 to perform dust removal treatment on the air in the roadway. When the piston rod 52 slides towards the end away from the liquid spraying port 541, the sealing plug 56 in the liquid spraying port 541 is repositioned at the liquid spraying port 541 under the action of the second spring to block the liquid spraying port 541, while the sealing plug 56 in the liquid supply port 542 is pressed to disengage from the liquid supply port 542, so that the water in the water supply chamber 53 is sucked into the hydraulic chamber 54, that is, the liquid in the hydraulic chamber 54 is replenished. Furthermore, by the reciprocating sliding of the piston rod 52, the atomizing mechanism 5 can continuously and effectively spray water mist, further ensuring that the atomizing mechanism 5 continuously and effectively performs dust removal treatment on the air in the roadway.

[0038] In this embodiment, as Figure 6, the adjustment mechanism 6 includes an adjustment base 61, a gear set 62, a rotating shaft 63, a driving rod 64, and a turntable 65. Among them, the adjustment base 61 is fixedly arranged at the bottom of the air outlet 11. Two slide rails 611 are fixedly arranged on the adjustment base 61. The gear set 62 is slidably arranged between the two slide rails 611. A support platform 612 is fixedly arranged on the adjustment base 61. A turntable 65 is rotatably arranged on the support platform 612. The turntable 65 is in transmission connection with the driving rod 64 through a bevel gear set. The rotating shaft 63 is slidably connected with the driving rod 64 through a snap pin. A driving gear is fixedly arranged on the rotating shaft 63. The driving gear meshes with the gears in the gear set 62.

[0039] In this embodiment, a chute 613 is formed on the adjustment base 61. An adjusting rod 66 is slidably arranged in the chute 613 through a hydraulic rod drive. Two ejector rods 661 are fixedly arranged on the adjusting rod 66. The ejector rods 661 are rotatably connected with the rotating shaft 63 and drive the rotating shaft 63 to slide horizontally.

[0040] Step-shaped push blocks 621 are arranged on both sides of the gear set 62. A third spring is arranged between the push blocks 621 and the slide rails 611. The ejector rods 661 slide along the push blocks 621 and lift the push blocks 621.

[0041] In this embodiment, an annular groove 651 is formed on the turntable 65, and a clamping groove 614 is formed on the support platform 612.

[0042] A guide rod 521 is fixedly arranged on the piston rod 52. The guide rod 521 is snapped into the clamping groove 614 and slides along the clamping groove 614. A clamping block 522 is fixedly arranged on the guide rod 521. The clamping block 522 is snapped into the annular groove 651 and slides along the annular groove 651.

[0043] In this embodiment, an axial flow fan two 212 is rotatably arranged on the support shaft two 211. The axial flow fan two 212 is in transmission connection with the gear set 62 through a pulley two 67. A tensioning wheel is arranged on the pulley two 67.

[0044] During implementation, the axial flow fan II 212 rotates under the shunting effect and drives the gear set 62 to rotate through the pulley II 67, causing the rotating shaft 63 to rotate. The rotation of the rotating shaft 63 drives the drive rod 64 to rotate, and under the action of the bevel gear set, the turntable 65 rotates, thereby causing the latch 522 to slide along the annular groove 651, causing the guide rod 521 to slide back and forth along the card slot 614, further driving the piston rod 52 to slide back and forth in the hydraulic chamber 54 to spray the liquid into the roadway. During this process, by driving the adjusting rod 66 to slide, the position of the rotating shaft 63 is changed, and under the action of the ejector rod 661, the gear set 62 is lifted, causing the driving gear to mesh with different gears in the gear set 62, thereby changing the rotation speed of the driving gear, further changing the rotation speed of the turntable 65, causing the sliding frequency of the piston rod 52 to change, and further changing the liquid spraying amount, i.e., the atomization intensity, of the atomization mechanism 5, so that the atomization mechanism 5 can be intelligently regulated according to the coal dust content and air humidity in the roadway.

[0045] In this embodiment, it further includes a monitoring module and a control module. Among them, the monitoring module monitors the oxygen content, toxic gas concentration, air humidity, and coal dust content in the roadway in real time through a variety of monitoring sensors, and transmits the monitored data to the control module. The control module is electrically connected to both the hydraulic rod and the monitoring sensors.

[0046] In summary, when the present invention is implemented, the monitoring module monitors the oxygen content, toxic gas concentration, air humidity, and coal dust content inside the roadway in real time. Subsequently, the control module controls the arc-shaped baffle 7 to open the corresponding air outlet 11 and air inlet 21 for local ventilation replacement of the roadway, replacing the toxic gas in the roadway and introducing fresh air. During the replacement process, the atomization mechanism 5 is used to remove dust from the air in the roadway and adjust the air humidity in the roadway, effectively improving the air quality in the roadway. The atomization intensity of the atomization mechanism 5 is adjusted through the adjustment mechanism 6 to perform intelligent dust removal on the air in the roadway. The coal dust in the air introduced into the air duct 2 is filtered by the filter component 3 to prevent the ventilation equipment from being blocked. During the filtering process, the coal dust in the filter component 3 is cleaned by the cleaning mechanism 4 to prevent the filter screen 34 from being blocked and affecting the filtering effect, thereby continuously and intelligently replacing the air in the roadway, making the air environment in the roadway always safe and having a higher air quality.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
