Description
Technical field
The present invention relates to a kind of optical transmitting set that can launch collimated light and adopt the method for optical transmitting set location, it is mainly used in analyzer is positioned.
Background technology
See also Fig. 1 and Fig. 2, the transmitter unit 1 of semiconductor laser gas analyzer and receiving element 2 are installed in the relative two ends of engineering pipeline 4 by linkage unit respectively, and described linkage unit comprises mounting flange 31 and instrument ring flange 32; Described mounting flange 31 is directly installed on the engineering pipeline 4, and described instrument ring flange 32 is arranged on the mounting flange 31, and transmitter unit 1 and receiving element 2 are installed in respectively on the instrument ring flange 32; The diameter of engineering pipeline 4 is several meters not to be waited to tens meters, and in order to reach the analysis requirement, under the perfect condition, transmitter unit 1 will overlap with the axis of receiving element 2.And in the installation process of reality, as long as transmitter unit 1 meets the demands with receiving element 2 axis runouts:
As, the diameter of engineering pipeline 4 is L, the axle center of transmitter unit 1 and receiving element 2 correspondences is respectively O
1And O
2, transmitter unit 1 is from O
1Point sends the A point that laser is radiated at receiving element 2 and is reflected, and is radiated at the B point of transmitter unit 1 end, as if the B point with respect to O
1The maximum deviation position of point still in transmitter unit 1 receiving plane, then meets the requirements to the location of transmitter unit 1 with receiving element 2; If the maximum deviation position has exceeded transmitter unit 1 receiving plane, then the location to transmitter unit 1 and receiving element 2 is inaccurate, need reorientate.The general deflecting angle that adopts is described the problems referred to above, that is:
Wherein, θ is BO
2With O
1O
2Between angle, l is a transmitter unit receiving plane maximum gauge.
When adopting optical transmitting set that analyzer is positioned, optical transmitting set is installed on the engineering pipeline by ring flange, the light that optical transmitting set sends is set at the mirror reflects on engineering pipeline opposite and returns, the light that reflects just meets the demands in transmitter unit is accepted face with respect to the maximum deviation position of optical transmitting set launch point, that is: the optical transmitting set deflecting angle of sending light also will satisfy above-mentioned requirements, that is: θ≤θ
0Then the light that optical transmitting set is sent is with respect to the angle θ of the central axis of its mounting flange
1Certain requirement is arranged, that is:
When this just requires optical transmitting set regulated, its angle of regulation range otherwise less than θ
1The scope that requires.
For the angle of regulation range that makes optical transmitting set can be applicable to location to analyzer, following solution is arranged: as shown in Figure 3, Figure 4, a kind of locator that is used for the analyzer location, comprise mount pad 5, laser diode 6, inner casing 7, battery 8 and shell 9, mount pad 5 is fixed on the ring flange of engineering pipeline; Laser diode 6, battery 8 be arranged in the inner casing 7 and with inner casing 7 one; Pass shell 9 and be provided with adjustment screw 10, adjustment screw 10 bottoms prop up inner casing 7, and when rotation adjustment screw 10, adjustment screw 10 is withstood inner casing 7 motions, to realize the adjustment to laser diode 6 angles;
The outside cylinder axis of laser diode 6 and the angle of light remain unchanged, as long as the outside cylinder axis of laser diode 6 and the angle of ring flange axis are not less than θ
1The scope that requires gets final product.
Above-mentioned solution can realize the adjustment to the locator certain angle, but also has following problem:
1, the optical transmitting set adjusting range is limited
By the distance between adjustment screw adjustment inner casing and the shell, to realize adjustment, so the adjustment angle of laser diode to the laser diode angle
Be subjected between inner casing and the shell restriction apart from d and inner casing length D:
The shortest length of inner casing length D is laser diode and battery length sum; Because
Satisfy the adjusting requirement, be the bigger the better, so the length of D is preferably just got its shortest length; Then laser diode is adjusted the restriction that angle just is subjected to d: by the precession and the back-out of adjustment screw, the amplitude that inner casing can be adjusted be to the maximum between inner casing and the shell apart from d;
1) if d is less than normal,
Adjusting range may be undesirable;
2) if d is bigger than normal,
Adjusting range increase, can reach requirement, but this moment because d is bigger than normal, make that the profile of locator is too big;
2, adjust trouble, length consuming time
Owing to be, realize the adjustment of distance between optical transmitting set inner casing and the shell, and then regulate the axis of laser diode and the angle of ring flange axis by precession or back-out adjustment screw; During adjustment, a plurality of adjustment screw need to regulate repeatedly, just can reach requirement, the adjustment process complexity, and the adjustment time is generally more than 10 minutes, and is consuming time longer;
Utilize adjustment screw that the inner casing end face is propped up and fix the inner casing of adjusting, can occur because the adjustment screw of other position is more dead to the location of inner casing yet, when adjusting wherein certain adjustment screw again, no matter precession or screw out, inner casing can not move; In order to reach the adjustment requirement, the screw of adjusting is before unclamped so again, transferred again, repeatable operation just might reach the adjusting requirement, wastes time and energy;
3, precision is not high
Utilize adjustment screw that the inner casing end face is propped up and fix the inner casing of adjusting, occur the state that inner casing is unsettled, adjustment screw does not prop up inner casing sometimes; The position instability that can cause optical transmitting set like this, if be subjected to situation such as external impacts, the position of inner casing may change, and makes the deterioration in accuracy of adjustment.
