ULTRASONICS WAVE DETECTING DEVICE PERFORMING DOMAIN AND PRECISE DETECTION FOR LONG DISTANCE AND ULTRASONICS WAVE GATHER APPARATUS AND INDEPENDENCE SERIES OF SENSOR MODULE DEVICE USING IN THE ULTRASONICS WAVE DETECTING DEVICE
The present invention relates to a device regarding a signal detecting unit for a step before a detecting signal is input to an amplifying circuit when ultrasonic waves generated from defect apparatuses of power equipment such as overhead power distribution lines are to be received from a distance and detected. In order to solve inconvenience in carrying, a short detection distance, and a narrow detecting angle at long distances, which are disadvantages of the conventional equipment, the present invention connects a waveguide (20) at a separate position (60) in front of the focus to a collecting tube (10) using a parabolic-shaped inner surface (50) in front of a focus (110) of a parabolic surface, not a parabolic type using a reflective surface in rear of the focus of a parabolic surface, and disposes a plurality of sensors in a wide area of the waveguide, thereby securing a wide detecting angle. Further, the waveguide accompanies a wide area of a collecting hole to increase a detectable distance. Further, a large signal amplitude can be obtained by an overlapping effect of an input signal by placing the plurality of sensors in the wide area of the waveguide and connecting the sensors in series. Only the center sensor can search for a precise (within 2°) location. A video camera (40) is mounted inside the collecting tube to display a circle and a distance calculation value for display of a detectable angle by distance and record and store a diagnostic process as a video. Therefore, the cause of diagnosis omission due to misalignment of a collecting angle can be eliminated, and a wrong determination of a diagnostician can be prevented by reanalysis.
