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
The present invention relates to a kind of instrument that is used to measure the boats and ships degree of dip, a kind of longitudinal clinometer that is used to measure boats and ships fore-and-aft tilt angle and draft difference of more specifically saying so.
Background technology
In the ship's navigation process, because the effect of wave, the situation that boats and ships have heel and trim takes place, and when navigation, and this angle of inclination does not change taking place all the time.In order to measure the maximum inclination angle of run-off the straight, there is a kind of equipment to be called clinometer in the nautical instrument, it is made up of a weight and a graduation apparatus, is commonly referred to as to be lateral inclinometer.The precision angle with smallest of the common energy measurement of this clinometer is 0.5 degree just, angle of heel appears in boats and ships in the navigation process possibility is very big, 1 degree～20 degree all belong to together normal, so it is unchallenged that conventional clinometer is used to measure the boats and ships heel, but will measure trim has just had certain degree of difficulty.For instance, for 300 meters long boats and ships, if trim 0.5 degree, the draft difference of bow stern just has more than 2.6 meters.Therefore, existing clinometer can't satisfy the needs of measuring trim angle.
Summary of the invention
The technical problem to be solved in the present invention provides the instrument and equipment of the caused draft difference of a kind of energy measurement boats and ships fore-and-aft tilt, to overcome the deficiency that can not accurately measure boats and ships trim value in the prior art.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: a kind of trim meter of ship, comprise one can receiving fluids communicating pipe, the two ends of described communicating pipe respectively connect one section transparent tube, the transparent tube opening upwards, and two transparent tube near be equipped with scale indicating device with respect to the transparent tube stationkeeping.
Preferably, described communicating pipe is the U-shaped pipe.
Preferably, described scale indicating device is the graduation apparatus of mint-mark on the transparent tube surface.
Preferably, described scale indicating device is the scaleplate that is fixed on the transparent tube back side.
Preferably, the distance between described two transparent tube is fixed.
Preferably, described transparent tube is a lucite tube.
The invention has the beneficial effects as follows: the present invention has utilized the principle of permeator dexterously, difference by the indicated scale of liquid level in two transparent tube, just can learn the draft difference of boats and ships bow stern at an easy rate, intuitive and convenient, simple in structure, the measuring accuracy height, being applicable to needs to measure on the boats and ships of trim value, such as passenger boat, pleasure boat.
Description of drawings
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Fig. 1 is the scheme drawing of trim meter of ship of the present invention.
Fig. 2 is the installation site scheme drawing of longitudinal clinometer on boats and ships.
Fig. 3 is the enlarged diagram of longitudinal clinometer high scale plate.
The specific embodiment
As shown in Figure 1, trim meter of ship of the present invention comprises the communicating pipe 4 of a U-shaped, and the top at two ends respectively connects one section transparent tube 1 in communicating pipes 4, and transparent tube 1 can adopt lucite tube.The opening of two transparent tube 1 makes progress, and each fixes a scaleplate 3 its back side.The perfusion certain amount of fluid makes two ends liquid level 2 be stable at the midway location of transparent tube 1 in communicating pipe 4, promptly can be used to instrumentation ship oceangoing ship trim.According to the principle of permeator, the shape of communicating pipe 4 might not be confined to U-shaped, also can be other shape, but should guarantee that the opening of two transparent tube 1 makes progress.Consider the smoothness that liquid flows in pipeline, the pipe diameter of communicating pipe 4 is Φ 25mm, and the pipe diameter of transparent tube 1 is Φ 23mm.The place that communicating pipe 4 is connected with lucite tube is coated with silica gel sealing, oozes out to prevent liquid.The pipeline planted agent of whole communicating pipe 4 cleans free from dust, should not have bubble behind the injection liquid and produces.
When longitudinal clinometer is installed on the boats and ships, must on the building berth of dock or level, carry out, should confirm when promptly installing that boats and ships are to be in horizontality.Longitudinal clinometer 6 can be installed on the longitudinal bulkhead 7 of boats and ships (as shown in Figure 2), promptly on the smooth bulkhead in the close ship on certain one deck deck, preferably on the aisle, make things convenient for the crewman to observe and calculate.The height of longitudinal clinometer is set to 1m usually, and setting height(from bottom) is set to the position that two ends liquid level 2 flushes with people's eyes height, probably is 1.6m.With Ω type pipe clamp 5 communicating pipe 4 is fixed on the bulkhead.Perfusion certain amount of fluid in communicating pipe 4 makes two ends liquid level 2 be stable at the midway location of transparent tube 1 then.At this moment, the water level at two ends is on same horizontal surface, and at the back side of transparent tube 1, each installs the scaleplate 3 (as shown in Figure 3) that a corrosion-resistant steel is made, and is fixed on the bulkhead with screw 8 around the scaleplate 3.Zero-bit on the scaleplate 3 is alignd with liquid level 2 in the transparent tube 1.Graduation apparatus 9 usefulness electroetching systems on the scaleplate 3 form, and are measure unit with mm, and accuracy of scale requires very high.Certainly, graduation apparatus 9 also directly mint-mark but can increase installation difficulty like this on the surface of transparent tube 1 because must guarantee the installation levelness of longitudinal clinometer itself, to guarantee after promptly installing that liquid level indicated scale in two ends is the same.
When boats and ships generation trim, the indicated scale of the liquid level at longitudinal clinometer two ends will change, and just can calculate the draft difference of boats and ships bow stern according to the liquid level difference at two ends.After longitudinal clinometer installed, the distance between its two transparent tube 1 was fixed, and this distance can design in proportion according to the length between perpendiculars of boats and ships.Such as, be example with the boats and ships of length between perpendiculars 300m, in 1: 25 ratio design, the width between centers between longitudinal clinometer two transparent tube 1 was 12m so, when the liquid level difference of 1mm appearred in the longitudinal clinometer two ends, the bow aft draft difference that just can calculate boats and ships in this ratio was 25mm.Therefore, under the certain situation of length ratio, the scale range of graduation apparatus 9 also will design according to the maximum trim value of boats and ships, and correspondingly, the maximum trim value is big more, and the length of transparent tube 1 is also longer.
