Description
Technical field
The utility model relates to laser displacement sensor detection technique field, is specifically related to a kind of water wheels guide vane servomotor laser displacement change and send device.
Background technology
In hydroelectric process, need in time to gather the feedback signal of guide vanes of water turbine aperture usually, with exerting oneself of control rotational speed of water turbine and genset.Because the displacement of guide vanes of water turbine servomotor piston is with the continuous random variation of practical operation situation in electrical network and power station, therefore, higher requirement has been proposed for the reliability of linear measurement guide vanes of water turbine servomotor piston displacement signals collecting.And existing potentiometer stay-supported guide vanes of water turbine servomotor shift transmission device, its inside is to have adopted potentiometer to come the angular displacement of sensing coiling drum, because potentiometer inside is abutted against the touch slide plate and is transmitted signal, the slide plate loose contact often appears in the practice, thereby instability, the poor reliability that causes output signal easy to wear greatly influenced the normal operation of system.
Summary of the invention
The purpose of this utility model provides a kind of water wheels guide vane servomotor laser displacement change and send device, it selects laser displacement sensor for use, be that device is sent in a kind of new type hydraulic turbine guide vane servomotor laser displacement change, the existing problem of old-fashioned shift transmission device can be avoided, the displacement of linear measurement guide vanes of water turbine servomotor can be steady in a long-term realized reliably.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises semiconductor laser 1, first eyeglass 2, second eyeglass 3, linear CCD array apparatus 4 and signal processor 5; Semiconductor laser 1 is connected with signal processor 5 respectively with linear CCD array apparatus 4, and a side of semiconductor laser 1 is provided with first eyeglass 2, and a side of linear CCD array apparatus 4 is provided with second eyeglass 3.
The utlity model has following beneficial effect: it selects laser displacement sensor for use, be that device is sent in a kind of new type hydraulic turbine guide vane servomotor laser displacement change, the existing problem of old-fashioned shift transmission device can be avoided, the displacement of linear measurement guide vanes of water turbine servomotor can be steady in a long-term realized reliably.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Referring to Fig. 1, this embodiment by the following technical solutions: it comprises semiconductor laser 1, first eyeglass 2, second eyeglass 3, linear CCD array apparatus 4 and signal processor 5; Semiconductor laser 1 is connected with signal processor 5 respectively with linear CCD array apparatus 4, and a side of semiconductor laser 1 is provided with first eyeglass 2, and a side of linear CCD array apparatus 4 is provided with second eyeglass 3.
The principle of work of this embodiment is: semiconductor laser 1 detects the first object a and the second object b, detects behind the object to handle by signal processor 5, measure the distance of object.
This embodiment is selected laser displacement sensor for use, be that device is sent in a kind of new type hydraulic turbine guide vane servomotor laser displacement change, the existing problem of old-fashioned shift transmission device can be avoided, the displacement of linear measurement guide vanes of water turbine servomotor can be steady in a long-term realized reliably.
