Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of liquid level position measurement in a marine fuel tank, in particular to a sensor for measuring the liquid level position in a marine fuel tank and a working method thereof. BACKGROUND

[0002] The fuel system is one of the important systems of the ship power system, and multiple fuel tanks and daily oil tanks are arranged on the ship to supply fuel for the ship. At present, the measurement of fuel in the ship fuel tank mainly focuses on the measurement of the fuel liquid level position. Through the measured liquid level height data and the tank capacity table, the remaining fuel quantity can be calculated. This is the main way and purpose of monitoring and measuring the fuel tank in the domestic ship (the measurement purpose is to determine how much remaining fuel).

[0003] The float sensor moves up and down with the change of liquid level or flow rate through the buoyancy of the float in the liquid, converts mechanical displacement into electrical signals or other measurable signals. The core components include a float, a guide mechanism, a displacement conversion device (such as magnetic coupling, potentiometer, photoelectric encoder, etc.), and a signal processing circuit. The float rises and falls with the liquid level, and the displacement is transmitted to the sensor through mechanical structure or magnetic coupling, and a signal proportional to the liquid level is output, and the liquid level is further measured.

[0004] Since the ship often travels on the water surface, when traveling on the lake or river surface, the waves on the water surface are small and do not cause too much shaking of the ship body. At this time, when using the float liquid level sensor, the remaining quantity of fuel in the fuel tank can be accurately measured. However, when the ship travels on the sea surface, the waves on the sea surface are large, which drives the ship body to shake, thereby driving the fuel tank on the ship body to shake, further causing the fuel in the fuel tank to shake, driving the float liquid level sensor to move up and down, and thus affecting the detection effect of the liquid level height in the fuel tank.

[0088] Working principle: The sensor for measuring the liquid level in the fuel tank of the ship and its working method has the following steps when in use:

[0089] First, use the flange 2 to vertically place the sensor in the fuel tank, then use the buoyancy between the buoy 5 and the fuel to make the buoy 5 float on the surface of the fuel, further make the buoy 5 in different positions of the fixed rod one 3 to measure the fuel level. When the ship floats, the fuel in the fuel tank will further fluctuate, further driving the buoy 5 to move up and down, sliding on the limiting rod one 6 and driving the rubber plate 35 to approach the surface of the fixed rod one 3, thereby hindering the displacement of the equipment box 4, further reducing the displacement of the resistance ring 7. At the same time, the displacement of the buoy 5 drives the displacement of the sleeve ring two 9, thereby changing the contact area between the buoy 5 and the fuel surface, further increasing the stability of the buoy 5 when the fuel slides. When the hull shakes violently, the gravity ball 19 will be further moved, pushing the curved rod one 27 to deflect, pushing the isolation plate 14 out of the plate opening 33, and blocking around the buoy 5, thereby reducing the impact of fuel floating on the buoy 5. At the same time, the isolation plate 14 is pressed, and the sponge cylinder 23 is also squeezed, making it difficult for the equipment box 4 to move, increasing the stability of the equipment box 4 on the surface of the fixed rod one 3. After the deflection of the curved rod one 27, the rubber sheet 18 will be in contact with the fixed rod one 3 by pulling the elastic rope 29, further preventing displacement of the resistance ring 7 when the fuel shakes violently. When the fuel level tends to be balanced, the spring one 26 restores the curved rod one 27, further restoring the rubber sheet 18 and the sponge cylinder 23, so that the equipment box 4 can normally slide on the surface of the fixed rod one 3.

10. A method for operating a sensor for measuring the liquid level in a marine fuel tank, the method being applicable to the sensor for measuring the liquid level in a marine fuel tank as claimed in claim 9, characterized in that: The following steps are involved: S1: Liquid level measurement: The sensor is placed vertically in the fuel tank using the flange (2). The buoyancy between the buoy (5) and the fuel is used to make the buoy (5) float on the fuel surface. The buoy (5) is then positioned at different positions on the fixed rod (3) to achieve fuel level measurement. S2: Floating buffer: When the ship floats, the fuel in the fuel tank will fluctuate, further driving the buoy (5) to move slightly up and down. During the process of the buoy (5) moving up and down, it will slide on the limit rod (6) and drive the rubber plate (35) close to the surface of the fixed rod (3), thereby hindering the displacement of the equipment box (4), further reducing the displacement of the resistance ring (7), and at the same time, the displacement of the buoy (5) drives the displacement of the sleeve ring (9), thereby changing the contact area between the buoy (5) and the fuel surface, further increasing the stability of the buoy (5) when the fuel slides; S3: Segmentation during violent shaking: When the hull shakes violently, it will further drive the gravity ball (19) to move, pushing the curved rod (27) to deflect, pushing the isolation plate (14) out from the plate outlet (33) to block the buoy (5), thereby reducing the impact of the floating fuel on the buoy (5). At the same time, when the isolation plate (14) is pressed down, it will also squeeze the sponge tube (23), making it difficult for the equipment box (4) to move, thereby increasing the stability of the equipment box (4) on the surface of the fixed rod (3); S4: Reduce sliding: After the bending rod (27) is deflected, the elastic rope (29) is pulled to make the rubber sheet (18) contact with the fixed rod (3), further preventing the resistance ring (7) from moving when the fuel shakes violently; S5: Reset and retest: When the fuel level reaches equilibrium, the spring 1 (26) causes the bent rod 1 (27) to return to its original position, further causing the rubber sheet (18) and the sponge tube (23) to return to their original position, thereby allowing the equipment box (4) to slide normally on the surface of the fixed rod 1 (3).
