Embodiment Construction

[0015] Such as figure 1 As shown, the ship trim gauge of the present invention includes a U-shaped connecting pipe 4, and a section of transparent pipe 1 is respectively connected to the tops of both ends of the connecting pipe 4, and the transparent pipe 1 can be a plexiglass pipe. The openings of the two transparent tubes 1 are upward, and a scale plate 3 is respectively fixed on their back sides. A certain amount of liquid is poured into the connecting pipe 4, so that the liquid surface 2 at both ends is stabilized at the middle position of the transparent pipe 1, which can be used to measure the trim of the ship. According to the principle of the connecting device, the shape of the connecting pipe 4 is not necessarily limited to a U-shape, but can also be other shapes, but it should be ensured that the openings of the two transparent pipes 1 are upward. Considering the smooth flow of the liquid in the pipeline, the pipe diameter of the connecting pipe 4 is Φ25mm, and the ...

Abstract

The invention discloses a trim meter of a ship, comprising a communicating pipe capable of containing liquid. Both ends of the communicating pipe are respectively connected with a section of transparent pipe; and the transparent pipes open upwards, and scale indication devices fixed relative to the positions of the transparent pipes are arranged nearby the transparent pipes. Through the invention, the fore and aft trim of the ship are easy to know through the difference value of scales indicated by liquid levels inside the two transparent pipes, and the invention is visual and convenient, has simple structure and high measuring accuracy and is suitable for the ships such as a passenger ship and a cruise ship which need to be measure a trim value.

Description

technical field [0001] The invention relates to an instrument for measuring the inclination of a ship, more specifically an inclinometer for measuring the longitudinal inclination angle and trim of the ship. Background technique [0002] During the sailing process of the ship, due to the action of the sea waves, the ship will have heel and trim, and the inclination angle is changing all the time during the sailing. In order to measure the maximum angle of inclination at which inclination occurs, there is a device in nautical instruments called an inclinometer, which consists of a weight and a scale, and is usually called a heel gauge. This kind of inclinometer can usually measure the angle with the smallest accuracy, which is 0.5 degrees. The ship may have a heel angle during navigation, and 1 degree to 20 degrees are common, so conventional inclinometers are used to measure ships. Heel is not a problem, but it is difficult to measure trim. For example, for a 300-meter-lon...
