Technical field
The present invention relates to β rays method PM10 on-line monitoring appearance sampling pipe, the especially jacking gear of β rays method PM10 on-line monitoring appearance sampling pipe.
Background technology
β rays method PM10 on-line monitoring appearance is one of China's main monitoring instrument of measuring pellet in the atmosphere at present.In observation process, calibration, sampling, counting and the output link that is absolutely necessary, and in these links, need sampling pipe to rise sometimes, need sampling pipe to descend sometimes.The descending operation of sampling pipe inconvenience at present, up-down degree of accuracy can not better controlled, so design operation is convenient, and the jacking gear of the on-line monitoring appearance sampling pipe that the up-down degree of accuracy is high becomes a kind of demand of enterprise.
Summary of the invention
The object of the invention just provides a kind of easy to operate, the β rays method PM10 on-line monitoring appearance sampling pipe of the band jacking gear that the up-down degree of accuracy is high.
The technical scheme that the present invention adopts is: β rays method PM10 on-line monitoring appearance sampling pipe jacking gear, it is characterized in that it comprises the passage body that is used for supporting sampling pipe, the mainboard that is used for fixing the passage body, press spring base, compression spring and press spring base jacking gear, and said passage body is provided with vertical hole; Sampling pipe is positioned at vertical hole and can moves up and down along vertical hole, and the passage body is provided with horizontal square hole and transverse slot, and the bottom surface, transverse slot is provided with filter paper; Filter paper is close in the sampling pipe bottom; The passage body is provided with gas passage below the sampling pipe of transverse slot, the sampling pipe top in the said transverse slot is set with pad, and press spring base is a solid of revolution; The cross section takes the shape of the letter U; The bottom is provided with the through hole that supplies sampling pipe to pass through, and through bottom through-hole and sampling pipe suit and affixed, compression spring is enclosed within on the sampling pipe; Two ends are pushed pad and press spring base respectively, and described press spring base jacking gear drive pressure spring abutment moves up and down and realizes that sampling pipe moves up and down.
Adopt technique scheme, when the upward movement of press spring base jacking gear drive pressure spring abutment, the pressure that press spring base will overcome compression spring rises; The drive sampling pipe rises; When press spring base jacking gear drive pressure spring abutment moves downward, will drive sampling pipe and descend, thereby realize that sampling pipe moves up and down.
Above-mentioned press spring base jacking gear comprises the fixed head that is connected on the mainboard, is installed in claw-pole motor and excentric sleeve on the fixed head; The U-shaped upper edge of described press spring base is provided with outwardly directed annular boss; Described excentric sleeve one end is fixed on the claw-pole motor output shaft, and the other end stretches in the horizontal square hole of passage body through the through hole on the mainboard, and the end is connected with the minor axis that deflects away from the excentric sleeve center; Minor axis is positioned under the annular boss of press spring base, and claw-pole motor is provided with photo interrupter.Above-mentioned press spring base jacking gear is when claw-pole motor rotates; Make the minor axis of front end make circular motion through excentric sleeve; Will promote annular boss drive press spring base moves up and down; Because photo interrupter can accurately be controlled the rotation of motor, so the up-down degree of accuracy of sampling pipe can be precisely controlled.
For reducing friction, be set with bearing on the described minor axis.
In sum, beneficial effect of the present invention is: 1, owing to adopt claw-pole motor to drive, make sampling pipe require to carry out automatically rise and fall according to reality, automaticity is high, and is easy to operate; 2, in the sampling pipe process of rising or falling, running is steady, and frictional resistance is little; 3, under the effect of compression spring, sampling pipe compresses filter paper, plays good sealing function, has improved sampling efficiency.
