Embodiment
Below in conjunction with the drawings and specific embodiments, a kind of stationary pollution source particle monitoring instrument optical table that the utility model provides is described in detail.
Fig. 1 illustrates a kind of stationary pollution source particle monitoring instrument optical table, comprise: main installing plate 1, be arranged on the window outgoing assembly of main installing plate side, optical fiber receive module, this optical fiber receive module is arranged on the optical fiber receive module of the opposite side relative with described window outgoing assembly of described main installing plate, and extend outstanding away from main installing plate 1 from described opposite side, light source assembly, light source assembly is arranged on the lower end of main installing plate 1, and arrange with optical fiber receive module homonymy, by this, the light sent by light source assembly can by window outgoing assembly and from the outgoing of window outgoing assembly, and filtering assembly, filtering assembly is arranged on optical fiber receive module inside and is arranged on the end away from main installing plate 1 of optical fiber receive module.
Window outgoing assembly can comprise window glass mounting blocks 5, window glass 4 and outgoing glass 6, window glass mounting blocks 5 is arranged in main installing plate 1, and window glass 4 and outgoing glass 6 are removably arranged on window glass mounting blocks 5 respectively, and window glass 4 and outgoing glass 6 not overlapping.
Optical fiber receive module can comprise: receiver lens seat 7, described receiver lens seat is arranged on the described opposite side of described main installing plate and stretches out outstanding, receiver lens 3 from this opposite side, this receiver lens is arranged on one end adjacent with described main installing plate 1, the circuit board for receiving 15 of described receiver lens seat 7, this circuit board for receiving is arranged on the other end away from described receiver lens and the optical receiver 14 of described receiver lens seat, and described optical receiver is connected to described circuit board for receiving.
Light source assembly can comprise: angle board 11, described angle board to be arranged on described receiver lens seat 7 and be arranged between described receiver lens 3 and described circuit board for receiving 15, laser transmission circuit plate 10, described laser transmission circuit plate is fixed to described angle board 11 and Laser emission assembly 8, and described Laser emission assembly is arranged on described laser transmission circuit plate.
Here, the angle of angle board 11 is fixing nonadjustable, this improves the reliability and stability of in-site installation and on-line checkingi.In addition, angle board 11 can be changed, like this, if when needing the parameters such as the angle of adjustment angle board, can adjust by changing angle board.
Filtering assembly can comprise: filter glass mounting blocks 13, described filter glass mounting blocks is arranged on the other end of receiver lens seat 7 and extends and filter glass 12 towards receiver lens 3 is inwardly outstanding, and described filter glass is alternatively arranged on the end extended towards receiver lens 3 of filter glass mounting blocks 13.Filter glass 12 can be the logical filter glass of band, and the light that it only allows the laser beam frequency that sends with laser instrument identical or close passes through, and this makes it possible to eliminating optical receiver and receives the possibility that other light source enters optical receiver.
Receiver lens seat 7 inwall arranges screw thread, and surface is black, can effectively absorb non-parallel light like this, thus greatly reduces non-parallel light in the internal reflection of receiver lens seat to the impact of measurement result.
