Referring to fig. 1-4, underground space situation detecting system, including detecting a protection section of thick bamboo 1, be equipped with empty gas detection survey equipment 21 in detecting a protection section of thick bamboo 1, an opening 2 has been seted up to the lower extreme that detects a protection section of thick bamboo 1, the embedded filter screen 3 that is equipped with of opening 2, it is provided with cavity pressure disk 4 to slide in detecting a protection section of thick bamboo 1, guide way 19 has been seted up on the inner wall that detects a protection section of thick bamboo 1, sliding connection has guide bar 18 in guide way 19, and the one end fixed connection that guide bar 18 kept away from guide way 19 is on the lateral wall of cavity pressure disk 4, the lower extreme fixedly connected with spring 20 of guide bar, the lower extreme fixed connection of spring 20 is at the interior bottom that detects a protection section of thick bamboo 1.
A plurality of clearance end caps 15 of lower extreme fixedly connected with of cavity pressure disk 4, install its drive arrangement who reciprocates of drive on the cavity pressure disk 4, detect the communicating toper section of thick bamboo 12 of lower extreme fixedly connected with and opening 2 of a protection section of thick bamboo 1, air inlet 13 has been seted up to the lateral wall of toper section of thick bamboo 12, the intercommunication of toper section of thick bamboo 12 lower extreme has blow off pipe 14, new trend groove 8 has been seted up to the lateral wall that detects protection section of thick bamboo 1, be equipped with air discharge fan 11 in the new trend groove 8, top and lateral wall communicate respectively in the new trend groove 8 has new trend intake pipe 10 and new trend outlet duct 9. It should be noted that, referring to fig. 1 and 2, the cleaning plugs 15 correspond to the filtering holes on the filter screen 3 one by one, the filtering holes on the filter screen 3 are only arranged in the middle of the filter screen 3, and the air inlets 13 are arranged on both sides of the edge of the conical cylinder 12, so that the dust falling from the filtering holes can fall into the middle of the conical cylinder 12 and be discharged from the sewage discharge pipe 14.
The driving device comprises an exhaust pipe 5 which is fixedly arranged at the upper end of the hollow pressure plate 4 and communicated with the inside of the hollow pressure plate, the upper end of the exhaust pipe 5 is communicated with a corrugated pipe 6, an exhaust hole 16 communicated with the inside of the hollow pressure plate 4 is formed in the side wall of the cleaning plug 15, and the aperture of the exhaust hole 16 is smaller than the pipe diameter of the exhaust pipe 5.
The side wall of the detection protection barrel 1 is provided with an air groove 17, an exhaust mechanism exhausting to the corrugated pipe 6 is installed in the air groove 17, the exhaust mechanism comprises a sliding plug 23 connected in the air groove 17 in a sliding mode, a reciprocating lead screw 22 is connected in the air groove 17 in a rotating mode, and the reciprocating lead screw 22 is in sealing threaded connection with the sliding plug 23. It should be noted that, because the aperture of the exhaust hole 16 is smaller than the pipe diameter of the exhaust pipe 5, and the exhaust volume of the exhaust hole 16 is smaller than the intake volume of the exhaust pipe 5, the air cannot be completely exhausted and will gather in the bellows 6, so that the air pressure in the bellows 6 is increased to force the bellows 6 to extend, and because the position of the one-way air outlet pipe 7 is fixed, the hollow pressure plate 4 will be pushed to move downwards. Furthermore, the one-way air inlet pipe 26 enables air to flow into the air groove 17 from the one-way air inlet pipe 26 in one way, and the one-way air outlet pipe 7 enables air to flow into the one-way air outlet pipe 7 from the air groove 17 in one way, and in addition, in the device, the one-way air outlet pipe 7 can push the hollow pressure plate 4 to move downwards for cleaning when exhausting, and air is sucked in the one-way air inlet pipe 26 to enable the air not to be cleaned, so that dust falling off after cleaning can have enough time to be discharged from the conical cylinder 12 and the sewage discharge pipe 14, and secondary pollution can not be caused.
The rotating shaft of the reciprocating screw rod 22 is coaxially and fixedly connected with the rotating shaft of the exhaust fan 11, the air groove 17 is communicated with the corrugated pipe 6 through the one-way air outlet pipe 7, and the bottom and the inner top in the air groove 17 are respectively communicated with a one-way air inlet pipe 26 and an air guide pipe 24. It should be noted that the space above the spool 23 can be communicated with the outside by providing the air duct 24, so that the spool 23 can move up and down without being obstructed. Further, the thread of the reciprocating screw rod 22 is only arranged at the middle part, as shown in fig. 4, so that the upper end of the reciprocating screw rod 22 can penetrate through the top part of the air groove 17 in a sealing way and is connected with the rotating shaft of the exhaust fan 11.
In the invention, after the exhaust fan 11 is started, overground fresh air can be continuously sucked in through the fresh air inlet pipe 10 and discharged into an underground space through the fresh air outlet pipe 9, so that the underground air is kept fresh and clean.
In the process, the rotating shaft of the exhaust fan 11 drives the reciprocating lead screw 22 to continuously rotate, so that the sliding plug 23 in threaded connection with the reciprocating lead screw 22 can reciprocate up and down in the air groove 17, and continuously sucks air from the one-way air inlet pipe 26 and then exhausts the air from the one-way air outlet pipe 7. When air is sucked from the one-way air inlet pipe 26, external underground air passes through the air inlet 13 and the filter screen 3 and enters the detection protection cylinder 1 for supplement, so that the detection equipment 21 arranged in the detection protection cylinder 1 can sense the underground air condition at the first time, and the monitoring accuracy of the detection equipment 21 on the underground air is improved.
When air is exhausted from the one-way air outlet pipe 7, the air can be blown into the corrugated pipe 6, is exhausted into the hollow pressure plate 4 through the air exhaust pipe 5 and is finally exhausted through the air exhaust hole 16, because the aperture of the air exhaust hole 16 is smaller than the diameter of the air exhaust pipe 5, most of the air cannot be completely exhausted at a time when the air is blown into the corrugated pipe 6, the air is gradually gathered in the corrugated pipe 6, the corrugated pipe 6 extends and pushes the hollow pressure plate 4 to move downwards, the cleaning plug 15 at the lower end of the hollow pressure plate 4 penetrates through the filtering hole of the filter screen 3 to clean out dust blocked in the filtering hole, the dust falls in the conical cylinder 12 below and is exhausted through the drain pipe 14, and when the air is exhausted from the air exhaust hole 16, the air flow can also blow and clean the filter screen 3 to promote the dust adhered to the filter screen 3 to fall off. When the sliding plug 23 moves upwards again and air is sucked from the one-way air inlet pipe 26, the one-way air outlet pipe 7 stops feeding air to the corrugated pipe 6, residual air in the corrugated pipe 6 is exhausted gradually, the spring 20 can push the hollow pressure plate 4 to move upwards to reset, and meanwhile, the corrugated pipe 6 is contracted. And because the sliding plug 23 is made of magnetic material, when the sliding plug 23 moves up and down in a reciprocating manner, the sliding plug can continuously enter and exit the spiral coil 25, so that the magnetic flux in the spiral coil 25 is continuously changed, the spiral coil 25 generates induced current and enables the electric vibrating piece 27 to be electrified to vibrate, and therefore the upper filter screen 3 can be continuously pushed against, and dust adhered to the filter screen 3 can be promoted to fall off.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
