Abstract

A device for measuring liquid sloshing force of a ship transporting liquid. The device includes a first cuboidal frame; a second cuboidal frame; a rotating mechanism; a dynamometer; and a liquid tank disposed in the second cuboidal frame. The second cuboidal frame is pivotally connected to the first cuboidal frame via the rotating mechanism. The first cuboidal frame includes a first horizontal plane frame, a second horizontal plane frame, a plurality of upright tubes connecting the first horizontal plane frame and the second horizontal plane frame, and an X-shaped support rod disposed between the first horizontal plane frame and the second horizontal plane frame. The second cuboidal frame includes a third horizontal plane frame including two longitudinal beams and two transverse beams, a longitudinal U-shaped bar disposed between the two transverse beams, and a plurality of transverse U-shaped bars disposed between the two longitudinal beams.

First claim

What is claimed is:

1. A device, comprising:
1) a first cuboidal frame, the first cuboidal frame comprising a first horizontal plane frame, a second horizontal plane frame, a plurality of upright tubes connecting the first horizontal plane frame and the second horizontal plane frame, and an X-shaped support rod disposed between the first horizontal plane frame and the second horizontal plane frame;
2) a second cuboidal frame, the second cuboidal frame comprising a third horizontal plane frame comprising two longitudinal beams and two transverse beams, a longitudinal U-shaped bar disposed between the two transverse beams, and a plurality of transverse U-shaped bars disposed between the two longitudinal beams;
3) a rotating mechanism, the rotating mechanism comprising a connection plate, a bearing seat comprising an axle hole and being fixed on the connection plate, and a hinge pin;
4) a dynamometer, the dynamometer comprising a tensiometer, a first regulator, and a second regulator; and
5) a liquid tank disposed in the second cuboidal frame, the liquid tank comprising a faceplate, two first side plates, two second side plates, a first base plate, a second base plate, a guide plate, and a baffle plate;
wherein:
the second cuboidal frame is pivotally connected to the first cuboidal frame via the rotating mechanism;
the plurality of transverse U-shaped bars is supported by the longitudinal U-shaped bar;
the X-shaped support rod comprises a junction and the connection plate is fixed on the junction; the hinge pin comprises a first end fixed on one of the two longitudinal beams and a second end disposed in the axle hole of the bearing seat;
the tensiometer is disposed between the first regulator and the second regulator; the first regulator is connected to the first horizontal plane frame, and the second regulator is connected to the third horizontal plane frame; and
the faceplate, the two first side plates, the two second side plates and the second base plate are connected to each other to form a compartment, and the first base plate is disposed in the compartment to divide the compartment into a first compartment and a second compartment; the guide plate is vertically disposed on the faceplate; the guide plate comprises a slot, and the first base plate comprises a surface having a groove; the baffle plate is disposed in the slot and extends into the groove; the faceplate comprises a ventilation hole; and the first base plate comprises a drain hole.

2. The device of claim 1 , wherein the first horizontal plane frame comprises two first longitudinal beams and two first transverse beams; the second horizontal plane frame comprises two second longitudinal beams and two second transverse beams; four ends of the X-shaped support rod are connected to one of the two first longitudinal beams and one of the two second longitudinal beams, respectively; and the two second longitudinal beams each comprise a support leg.

3. The device of claim 1 , wherein the connection plate comprises four corners and the X-shaped support rod comprises four bars respectively disposed on the four corners.

4. The device of claim 1 , wherein the second cuboidal frame further comprises a diagonal brace and a plurality of support plates; the plurality of transverse U-shaped bars is fixed on the diagonal brace; and the plurality of support plates is clamped between two ends of each of the plurality of transverse U-shaped bars, respectively.

5. The device of claim 2 , wherein the dynamometer further comprises a first suspension ring connected to the first regulator and fixed on a middle part of one of the two first transverse beams via a first bolt, and a second suspension ring connected to the second regulator and fixed on a middle part of one of the two transverse beams via a second bolt.

6. The device of claim 1 , wherein the bearing seat is fixed on the connection plate through a plurality of connecting bolts and nuts.

7. The device of claim 1 , wherein the liquid tank comprises three guide plates, three baffle plates, and four side plates; the second base plate comprises a lightening hole; the surface of the first base plate comprises three grooves; one end of each baffle plate is clamped in each three groove; the three guide plates and the four side plates are connected to one another and fixed on the faceplate.
