Abstract
The utility model relates to a photoelectric tension wire coordinatograph which comprises a light source arranged in a sealing shell, a transparent flat lens, a filter lens and a charge-coupled device (CCD); a tension wire is positioned in an open slot of the shell; the transparent flat lens and the filter lens are respectively arranged on transparent windows that are parallel and opposite at the two sides of the open slot; the light source is arranged in parallel with the transparent flat lens; a reflecting flat lens forming an angle of 45 degrees with the light axis of the light source is arranged in front of the light source and the intersection point of the central line of the transparent flat lens and the light axis of the light source is caused to be in the center of the reflecting flat lens. The light source is arranged in parallel with the transparent flat lens; the limited space in the sealing shell is fully utilized to arrange the light source with relatively large volume; the reflecting flat lens is added, so the light path is changed without changing the measuring principle; the purpose of reducing the volume of the coordinatograph is realized, and thus the coordinatograph is convenient for on-site installation and the sealing performance of the coordinatograph is ensured.
Description
Technical field
The utility model relates to a kind of photo-electric that is used for the dam horizontal displacement monitoring and draws the bracing cable coelosphere, belongs to the displacement measuring instrument technical field.
Background technology
It is a kind of Basic Measuring Instrument of monitoring dam horizontal displacement that photo-electric is drawn the bracing cable coelosphere.At present, the composition that photo-electric is drawn the bracing cable coelosphere comprises the light source that is contained in the seal casinghousing, the flat mirror of printing opacity, optical filtering, charge coupled device ccd, draw the open slot that bracing cable places housing, flat mirror of printing opacity and optical filtering lay respectively on the optical transmission window of open slot both sides parallel opposed longer sides, light source is installed perpendicular to the flat mirror of printing opacity, during measurement, the directional light that light source sends directly vertically shines on the bracing wire body by the flat mirror of printing opacity, pass through optical filtering again, the light path that will contain the bracing wire body positional information projects on the CCD, the signal that CCD is gathered carries out data analysis, just can obtain the position of bracing wire body, and calculate the relative displacement of drawing bracing cable.Existing photo-electric is drawn the bracing cable coelosphere and is existed following defective: because light source is with to draw bracing cable perpendicular, and the light source volume is bigger, make that the whole volume that draws the bracing cable coelosphere is bigger, install very inconvenient, and draw the bracing cable system for what be installed on the dam end face, because the restriction in place, for bigger the drawing the bracing cable coelosphere even can not install of volume.
Summary of the invention
Technical problem to be solved in the utility model is, provides the improved photo-electric of a kind of light path to draw the bracing cable coelosphere, so that effectively dwindle the volume of coelosphere, is convenient to on-the-spot the installation.
The technical scheme in the invention for solving the technical problem is as follows: a kind of photo-electric is drawn the bracing cable coelosphere, its composition comprises the light source that is contained in the seal casinghousing, the flat mirror of printing opacity, optical filtering, charge coupled device ccd, draw the open slot that bracing cable places housing, flat mirror of printing opacity and optical filtering lay respectively on the optical transmission window of open slot both sides parallel opposed longer sides, it is characterized in that light source is parallel to the flat mirror of printing opacity and installs, having an optical axis included angle with light source in light source the place ahead is 45 ° reflective flat mirror, and makes the intersection point of the center line of the flat mirror of printing opacity and light source optical axis be positioned at the center of this reflective flat mirror.
The further technical scheme that the utility model solves its technical matters is as follows: be separately installed with heating plate on the flat mirror of described printing opacity, optical filtering.
The beneficial effects of the utility model are as follows: light source is parallel to the flat mirror of printing opacity and installs, make full use of space limited in the seal casinghousing and come the bigger light source of installation volume, increased the flat mirror of reflection, light path changes to some extent and measuring principle is constant, the purpose that the coelosphere volume is effectively dwindled in realization, be convenient to on-the-spot the installation, guaranteed the sealing of coelosphere.During measurement, the directional light elder generation that light source sends, vertically shines on the bracing wire body by the flat mirror of printing opacity again to the flat mirror of printing opacity by reflective flat mirror reflection, and by optical filtering, the light path that will contain the bracing wire body positional information projects on the CCD again.
Description of drawings
Fig. 1 draws bracing cable coelosphere one-piece construction cut-open view for the utility model photo-electric.
Embodiment
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.
As shown in Figure 1, the composition that the utility model photo-electric is drawn the bracing cable coelosphere comprises the flat mirror 3 of the light source 10, the printing opacity that are contained in the seal casinghousing 1, optical filtering 5, charge-coupled device (CCD) 4, draw the open slot 7 that bracing cable 8 places housing, the flat mirror 3 of printing opacity lays respectively on the optical transmission window 11,12 of open slot both sides parallel opposed longer sides with optical filtering 5, light source 10 is parallel to the flat mirror 3 of printing opacity and installs, having an optical axis included angle with light source in light source 10 the place aheads is 45 ° reflective flat mirror 2, and makes the intersection point of the center line of the flat mirror 3 of printing opacity and light source 10 optical axises be positioned at the center of reflective flat mirror.6 is transformer among Fig. 1, and 9 is cable splice.
Haze in order to prevent that steam from building up on the flat mirror 3 of printing opacity of optical transmission window 11,12, optical filtering 5, the further feature of the utility model is: as shown in Figure 1, on the flat mirror 3 of printing opacity, optical filtering 5, heating plate 31,51 is installed respectively, this measure can be measured instrument normally under very moist environment, eyeglass can be not mouldy.
