The invention discloses a horizontal apparatus for an azimuth compass repeater. The horizontal apparatus comprises an outer ring, an installation base, a longitudinal motor, a lateral motor, an innerring, a longitudinal inclination angle sensor, a lateral inclination angle sensor and a control module, wherein the outer ring is fixed on the installation base through a longitudinal rotation shaft,the longitudinal motor is fixed on the installation base, the rotation shaft of the longitudinal motor is fixedly connected to the outer ring, the lateral motor is fixed on the outer ring, the rotation shaft of the lateral motor is fixedly connected to the inner ring, the inner ring is fixed in the outer ring through a lateral rotation shaft, an azimuth compass repeater is fixed in the inner ringthrough a fastening member, and the longitudinal inclination angle sensor and the lateral inclination angle sensor are fixed on the inner ring and are respectively and electrically connected to the control module. According to the present invention, by arranging the azimuth compass repeater on the horizontal apparatus, the horizontal state can be always automatically maintained without manual intervention; during the observation, the operator can manually control the level of the azimuth compass repeater at any time without distraction so as to reduce the operation difficulty; and especially the generation of the large error during the vigorous shaking of the ship can be avoided.
Description
technical field [0001] The invention relates to the technical field of ship navigation, in particular to a leveling device for an azimuth compass. Background technique [0002] A compass is an instrument used in navigation to determine heading and azimuth. At present, the compass equipped on the ship includes a gyro compass and a magnetic compass. The gyro compass is made by using the principle that the high-speed rotating gyroscope can force its rotation axis to remain in the meridian plane after being properly damped. The gyro compass can drive several sub-compass (also known as compass repeater). The azimuth sub-compass is generally installed on both sides of the cab, and it is synchronized with the main compass. The operator can use the azimuth sub-compass and the azimuth circle to observe the azimuth of objects (including celestial bodies) conveniently. [0003] In nautical science, using azimuth compass and azimuth circle together to observe low-altitude solar azimu...
