Detailed description of the invention
See Fig. 1, stack aqueous rubbish 2 in burning power plant sanitary fill hole 1, the diafiltration produced in aqueous rubbish 2
Liquid will flow in the percolate passage 6 that sanitary fill hole is other by paliform barrier, the too much or moisture at sanitary fill
In the case of relatively big, in percolate passage 6, form percolate source of release 3(percolate horizontal plane).Inventive embodiments automatic floating
Formula gas detection apparatus 4 is installed on higher position, percolate passage 6 side, and lower section is connected to gas catalysis physical prospecting 5.
Seeing Fig. 2, Fig. 3, embodiment of the present invention automatic floating gas detection apparatus 4 is outside uses integrated explosion-proof shell
21, front and back it is respectively arranged with two round screw threads and uncaps, facilitate inner member installation, maintenance, each reserved standard electrical interface 22 in left and right, use
In the later stage, wiring and Function Extension are installed.
Explosion-resistant enclosure 21 is broadly divided into upper and lower two parts, and top is divided into controller, comprises one-chip computer module 23, display operation
The parts such as assembly 24, connecting terminal block, are conventional design, are not repeating.Lower part comprises micromachine 25 by anti-
Quick-fried shell is fixed, and micromachine 25 rotor connects reel 26, and the opposite side of reel 26 is equipped with disc-type slide ring 27, disc-type slide ring
The effect of 27 is when reel 26 rotates, and the wire of the slip ring left and right sides is connected by annular metal sheet, thus avoids side
The problem that wire is wound around occurs.One-chip computer module 23 is gone to automatic floating gas detection apparatus 4 bottom and is divided into three holding wires,
Wherein one is micromachine control signal wire 28, is connected to micromachine 25, is responsible for controlling its start-stop and rotation direction；Additionally
Two are respectively probe signal line 29 and infrared distance sensor holding wire, are respectively connecting to probe ring and the survey of disc-type slide ring 27
Away from ring, then drawing through the connection rope 30 reel 26 from probe ring, ranging reticle respectively, probe signal line 29 removes gas downwards
Body catalytic materials probe 5, is responsible for transmission probe detectable signal；Infrared distance sensor holding wire is with infrared distance sensor 32 even
Connect, be responsible for the distance gathering gas catalysis physical prospecting 5 with percolate source of release 3.
Catalytic materials probe 31 and infrared distance sensor 32, be installed in special dust cover 33, dust cover 33 surrounding
Opening paliform otch, facilitate air to circulate, lower section reserving hole, the infrared ray enabling infrared distance sensor 32 to launch is free
Pass through；Gas catalysis physical prospecting 5 is responsible for being converted to the concentration signal of gas the signal of telecommunication, thus obtains the concentration values of gas；
Infrared distance sensor 32 is installed on below probe 5, is responsible for the distance measuring gas catalysis physical prospecting 5 with percolate source of release 3,
Thus guide one-chip computer module 23 to control micromachine 25 and drive reel 26 to rotate, thus change gas catalysis physical prospecting 5
Position so that gas catalysis physical prospecting 5 distance source of release distance remain within the scope of state-set standard.
Seeing Fig. 4, the concrete operation workflow of control method of automatic floating gas detection apparatus 4 of the present invention is: be first
Initialization step, user inputs gas catalysis physical prospecting 5 away from percolate source of release 3 apart from (this reality by display operating assembly 24
Executing example is 10 centimetres, can arrange according to actual needs), (assay intervals time t) etc. join infrared distance sensor 32 setting cycle
Number；Then controller carries out preliminary treatment and self-inspection to the data of input, if user input values is beyond device range of accommodation
Or gas catalysis physical prospecting 5, the faulty then display alarm signal prompting on display operating assembly 24 of infrared distance sensor 32
User maintenance, after self-inspection is passed through, controller will read infrared distance sensor 32 data, control micromachine 25 and drive reel
26 rotate, and make the distance of gas catalysis physical prospecting 5 to percolate source of release 3 equal to user's setting value, it is achieved to calibrate for the first time；Then
After elapsed time t, one-chip computer module 23 will again read off infrared distance sensor 32 data, and the distance set with user is carried out
Relatively, if difference is more than 10cm, then one-chip computer module 23 controls the distance of gas catalysis physical prospecting 5 to percolate source of release 3
Equal to user's setting value；Finally by repeat the above steps so that gas catalysis physical prospecting 5 is along with the floating of percolate source of release 3
And changing position so that the distance of gas catalysis physical prospecting 5 to percolate source of release 3 remains at the model of state-set standard
Within enclosing.
