The working principle of the monitoring and coupling integrated protection device for the rock burst of the deep mine provided by the invention is as follows:
firstly, erecting the bottom protection plate 21 and the upper protection plate 23, rotating the support rod 22, adjusting the length of the support rod 22 to enable the bottom protection plate 21 to be tightly attached to the surface of the rock body 1, then installing the monitor 27 at the corresponding position of the upper protection plate 23 to enable the monitor 27 to be inserted into the rock body 1, and switching on an external power supply to enable the monitor 27 to be electrified; when rock mass 1 collapses to generate a large amount of dust, the dust can permeate into a roadway through gaps and the like of the protective structure 2, the monitor 27 monitors that the rock mass 1 vibrates, the motor 42 and the spraying structure 7 are started, the spray head 72 sprays water mist, meanwhile, the motor 42 drives the fan 41 to rotate, the fan 41 sucks the dust in the roadway into the dust removal box 31 through the ventilation opening 24, the dust is blocked by the filter screen 43 to block large-particle rocks outside, and groundwater and the like in the rock mass 1 can enter the dust removal box 31 through the ventilation opening 24 to avoid dripping into the roadway; dust enters the dust removal box 31, the water sprayed by the spray head 72 wets the dust and falls into the bottom of the dust settling chamber 34, meanwhile, the upper protection plate 23 and the bottom protection plate 21 are squeezed by shock waves generated by rock burst, the bottom protection plate 21 and the upper protection plate 23 block rock fall out to avoid roadway collapse, the upper protection plate 23 slides up and down in the buffer groove 25, and the buffer spring 26 deforms up and down to offset impact caused by partial vibration waves; at the same time, the fan 41 drives the rotating shaft 44 to rotate, the rotating shaft 44 drives the gear 45 to rotate, the gear 45 is meshed with the transmission gear slot 54, the rotation of the gear causes the transmission gear slot 54 to ascend, the transmission gear slot 54 drives the sliding block 53 to ascend, the first spring 52 is pressed by the sliding block 53, the sliding column 56 slides from the top end of the left slideway of the guide rail 55 to the bottom end of the sliding column, because the bottom end of the guide rail 55 is a slideway with a downward inclination, when the sliding column 56 slides to this position, because the transmission gear slot 54 continues to ascend, the movement of the sliding column 56 in the guide rail 55 forces the transmission gear slot 54 to move leftwards (according to the direction of fig. 2), and meanwhile, the sliding block 53 slides at the top end of the transmission gear slot 54, when the sliding column 56 slides to the slideway on the right side of the guide rail 55, the driving gear slot 54 is separated from the gear 45, at this time, the first spring 52 is reset to push the driving gear slot 54 to move downwards, the sliding column 56 slides upwards from the bottom end of the right slide way of the guide rail 55, when the sliding column 56 slides to the top end of the right slide way of the guide rail 55, because the top of the guide rail 55 is an upwards inclined slide way, the first spring 52 continues to push the driving gear slot 54 to move downwards, so the movement of the sliding column 56 in the guide rail 55 forces the driving gear slot 54 to move rightwards, finally, the driving gear slot 54 is meshed with the gear 45 again, the sliding column 56 just slides to the top end of the left slide way of the guide rail 55, the sliding block 53 slides at the top end of the driving gear slot 54, the gear 45 rotates to drive the driving gear slot 54 to ascend again, and the gear 45 rotates, so that the driving splines 54 repeat the above movement all the time; the ascending of the driving tooth socket 54 drives the connecting column 61 to ascend and the connecting column 61 drives the pressure plate 64 to slide upwards in the compression chamber 62, and since the muddy water in the dust chamber 34 flows into the feed port 63 along the inclined bottom surface and enters the top surface of the pressure plate 64 from the feed port 63, and the pressure plate 64 and the compression chamber 62 form a vacuum, when the pressure plate 64 slides upwards, the baffle 68 in the piston port 66 slides downwards, the third spring 67 is extended, the muddy water on the top surface of the pressure plate 64 enters the compression chamber 62 through the piston port 66, when the driving tooth socket 54 moves downwards, the connecting column 61 pushes the pressure plate 64 to slide downwards, the baffle 68 is pressed upwards by the muddy water in the compression chamber 62 to block the piston port 66, the third spring 67 is shortened, and simultaneously the pressure plate 64 presses the muddy water in the compression chamber 62, the second spring 65 is contracted, the connecting column 61 slides on the top of the pressure plate 64, and impurities flow into the drainage chamber 35 through the semipermeable membrane, and are pressed into cakes by the pressure plate 64; the impurities in the compression chamber 62 can be taken out through the sludge removing opening 32, and the water in the water filtering chamber 35 can be discharged through the water discharging opening 33. The device has the advantage of being able to absorb and process escaping dust.
