A Portable Multipurpose Inclinometer

Abstract

The utility model relates to a portable multipurpose inclinometer, which belongs to the technical field of ship measuring tools and is used for observing the inclination angle of a ship's hull when loading and unloading cargo. Its technical solution is: it includes a base plate, a horizontal plate, a dial, a fixed seat and a pendulum. The fixed seat and the base plate are respectively adsorbed on the hull by the magnets installed inside. The suspender is horizontally connected to the fixed seat. The line is hoisted under the boom, the horizontal plate is vertically connected to the base plate, the surface of the base plate and the horizontal plate is perpendicular to the horizontal plane, there are scales on the plate surface of the base plate and the horizontal plate, and the pendulum line is connected to the scale plate on the base plate and the horizontal plate relatively. Measure the ship's heel and trim angles through the pendulum line and the dials on the base plate and transverse plate. The present invention has the characteristics of high sensitivity, high accuracy, convenient installation, simple use, and timely correction of errors found. risk.

[0002] When the ship is loading and unloading cargo in the port, it is necessary to use an inclinometer to observe the inclination angle of the hull. Currently, the pendulum inclinometer is widely used in bulk carriers. The disadvantages of this pendulum inclinometer are: first, its Low sensitivity, according to the requirements of CB / T3376-2005, the sensitivity is not greater than 0.4°; secondly, the accuracy is low, the division value is large, and the minimum scale is 1°; moreover, due to installation errors, improper fixing of the substrate, and excessive service life Long-term reasons such as loosening of fixing parts and corrosion of swinging parts cause large angle errors, which cannot accurately reflect the angle of ship deflection, and inaccurate inclinometers will bring a lot of inconvenience and risks to the ship and the port; the fourth , The marine inclinometer is fastened on the ship by screws, and it is not easy to correct after the error is found; fifth, due to the large error, the water gauge correction calculation cannot be performed according to the angle displayed by the inclinometer at the stage of adjusting the water gauge; sixth, the inclination The inclinometer belongs to the ship's auxiliary equipment and the port does not have corresponding equipment or standards, so the port staff can only judge the inclination angle based on the inclinometer installed on the ship, and the standards of the inclinometer installed on different ships are different. The accuracy is not the same, which increases the difficulty and risk of the work for the staff; finally, the traditional marine inclinometer can only display the heel angle of the hull but not the trim angle at the same time

Due to the above-mentioned many defects of the pendulum-type inclinometer, it can no longer meet the needs of the modern production of the port. It is necessary to design a new instrument for measuring the inclination angle of the ship to meet the needs of the ship and the port.
