The present invention relates to a gas leakage detection device, and more particularly, to a gas leakage detection device, and more particularly, to a bracket for supporting a mounting plate such that a mounting plate guides the gas detection beam transmitter or the gas detection beam receiver, The gas detection beam transmitter and the gas detection beam receiver are arranged in the center line L1 and L2 of the respective mounting posts through the left and right movement of the mounting plate even under the situation of inconsistency of position of each fixing post, It is possible to guide the operator of the gas leakage detection device to flexibly remove the problem of quality degradation due to a center line discrepancy between the gas detection beam transmitter and the gas detection beam receiver To a gas leakage detection device.

BACKGROUND ART [0002] In recent years, various types of gas leakage detection devices capable of detecting gas leakage from piping, tanks, and the like have been developed / distributed while major accidents occur frequently due to gas leakage.

For example, in Korean Patent Laid-Open No. 10-2008-93189 (titled "Gas Leakage Detection System and Gas Leak Detection Method of Gas Supply System") (published October 21, 2008) Is disclosed in more detail.

1, the gas leakage detecting device 10 according to the related art includes a gas detecting beam emitting unit 10 for detecting whether gas is leaked through a series of ultraviolet beams B, (20) and the gas sensing beam receiving unit (30) are systematically combined.

In this case, the gas sensing beam emitting unit 20 includes a fixing post 27 defining a reference position of the unit 20, a protruding block 26 protruding from the fixing post 27 side, A bracket 24 fixed to the protruding block 26 and a middle connecting block 22 via a clamping tool 25 such as a bolt or U-bolt, A mounting plate 23 fixed to the bracket 24 in a state where the mounting plate 21 is fixed, and the like are structured in a systematic combination.

The gas sensing beam receiving unit 30 paired with the gas sensing beam emitting unit 20 includes a fixing post 37 defining a reference position of the unit 30, A bracket 34 fixed to the projecting block 36 via a fastening tool 35 such as a U-bolt and the like, A mounting plate 33 fixed to the bracket 34 in a state in which the gas sensing beam receiver 31 is fixed via the gas sensor 32 is systematically combined.

2, the mounting plates 23 and 33 and the brackets 25 and 35 provided in the gas sensing beam emitting unit 20, the gas sensing beam receiving unit 30 and the like are inserted into the insertion holes And fastening tools 23a and 33a such as screws passing through the insertion holes 23a and 24a and the insertion holes 23b and 33b.

3, the gas sensing beam emitter 21 provided in the gas sensing beam emitting unit 20 is operated by an operation of rotating along the arrow R1 via the intermediate connection block 22, So that the ultraviolet beam B emitted from the ultraviolet beam B can be more accurately transmitted to the gas sensing beam receiving unit 30 side, The beam receiver 31 also operates to rotate along the arrow R2 via the intermediate connection block 32 so that the ultraviolet beam B transmitted from the gas sensing beam emitter 21 side So that it can be received more accurately.

On the other hand, under such a conventional system, in order for the gas leakage detection device 10 to exhibit a more excellent gas leakage detection performance, the gas detection beam transmitter 21 and the gas detection beam receiver 31, which are mutually paired, The center lines L1 and L2 must coincide with each other (see FIG. 3).

Of course, in order to match the center lines L1 and L2 of the gas detecting beam emitter 21 and the gas detecting beam receiver 31, a fixing post 27, 37) must also be installed very precisely at their corresponding positions (see FIG. 3).

However, since the fixing posts 27 and 37 defining the reference positions of the units 20 and 30 are generally spaced apart from each other at regular intervals, as long as no special measures are taken, each of the units 20 and 30 The fixing posts 27 and 37 which define the reference positions of the fixing posts 27 and 37 can not be installed in a very precise position corresponding to each other. The process of resetting also involves a complicated operation of the firearm, so that there are many difficulties in real life). As a result, on the gas leak detector operating side, the gas detecting beam transmitter 21 and the gas detecting beam receiver 31 The gas sensing beam transmitter 21 and the gas sensing beam receiver 31 are connected to the center line L1 and L2 in the direction of the arrow R1 , R2), but such a rotation operation has little help in terms of matching of the center lines L1, L2).

To solve this difficulty, the gas sensing beam emitter 21 and the gas sensing beam receiver 31 are moved left and right along the arrows S1, S2, through which the gas sensing beam emitter 21 and the gas sensing A procedure for matching the center lines L1, L2 of the usable beam receiver 31 is desperately needed.

However, in spite of this situation, the conventional mounting plates 23 and 33 and the brackets 25 and 35, which support the gas sensing beam emitter 21 and the gas sensing beam receiver 31, Is structured so as to be strongly engaged with and fixed to each other through fastening tools 23a and 33a such as screws passing through the insertion holes 24a and 34a and the insertion holes 23b and 33b, It is difficult for the operator to move the gas sensing beam transmitter 21 and the gas sensing beam receiver 31 left and right along the arrows S1 and S2 so that the gas sensing beam transmitter 21 and the center line L1, L2 of the gas sensing beam receiver 31, the quality of the product is deteriorated.

Korean Patent Laid-Open No. 10-2008-93189 (Name: Gas Leakage Detection System and Gas Leakage Detection Method of Gas Supply Device) (2008.10.21 published)

Accordingly, the object of the present invention is to further arrange a guide slit < guide > for guiding the mounting plate to move left and right in a state where the gas sensing beam transmitter or the gas sensing beam receiver is fixed, to the bracket supporting the mounting plate , Thereby allowing the gas sensing beam emitter and the gas sensing beam receiver to precisely match their respective center lines (L1, L2) through lateral movement of the mounting plate even under the position mismatch situation of each stationary post And guiding the operator of the gas leakage detection device to flexibly remove the problem of quality degradation due to a center line discrepancy between the gas detection beam transmitter and the gas detection beam receiver.

However, since the fixing posts 207 and 307 defining the reference positions of the units 200 and 300 are generally spaced apart at regular intervals, the reference positions of the units 200 and 300 are defined as long as no measures are taken (Of course, the procedure of repositioning once fixed / installed stationary posts 207, 307 is also a complicated process of firearms). The center line L1 and L2 of the gas detecting beam transmitter 201 and the gas detecting beam receiver 301 are aligned with each other at the gas leak detector operating side Even so, we have to suffer great difficulties.

In this case, The fastening tool 303a such as a screw is inserted into the insertion hole 303b on the side of the mounting plate 303 after the center lines L1 and L2 of the gas sensing beam receiver 301 are aligned with each other, And the mounting plate 303 is inserted into the guide slit 310 on the bracket 304 side to advance the process of fixing the mounting plate 303 to the bracket 304. In this case, Additional elements such as washers and nuts may be additionally installed, Also shown is omitted) on the.

When the above procedure is completed, only the mounting plates 203 and 303 are fixed to the brackets 204 and 304 without complicated procedures such as resetting the positions of the fixed posts 207 and 307 once fixed / installed on the gas leak detector operating side.
