<p>The invention relates to a device for measuring a drilled hole axis deviation versus the projected vertical or deviated axis, the measured zenithal angle being 0-50 degrees. The device, according to the invention, consists of a sub-assembly for fixing the used image, mounted in connection with some sub-assemblies for the determination of the zenithal and azimuthal angles, of illumination disinfestation; the sub-assembly for determining the zenithal and azimuthal angles consists of a tubular case, with a reflecting inner surface which delineates a room, where there is a pendulum of a length equal to the curving radius of an engraved glass; the diameter of the circles engraved on the upper surface of the glass has a value equal to the sinus of the angle between the pendulum and the room axis multiplied by two times the pendulum length; the illumination sub-assembly consists of a support, provided with some bulbs, threaded inside, is made of electrically conductive material, in the upper part, the bulbs come in contact with a sleeve made of electrically conductive material; the support is connected in the lower part to the threaded plug of a cylindrical support belonging to the disinfestation sub-assembly; this also consists of a deflector, with a reflecting outer surface, with some cylindrical upper parts and respectively tronconical lower part, long base facing downward; at the cylindrical upper part, the deflector is attached to the cylindrical support, which is made of opaque, electrically nonconductive material and has an upper circular collar, that connects to the sleeve, in its turn fastened with some collar screws.</p> |
