[0002] The ship tilt test is an effective method to obtain the actual weight and center of gravity height of the ship after completion by heeling the ship. The ship weight and center of gravity position measured and calculated by the test are the basic data for calculating the stability of the ship, and have a direct impact on the correctness of the ship stability calculation. The tilt test plays an important role in the delivery of the ship and the future operation of the ship. For example, the prior art: CN218317209U, a ship tilt test device, including: a hanging pendulum assembly and a measuring assembly, the hanging pendulum assembly includes a suspension bracket, a cycloid and a pendulum, the cycloid One end is connected to the suspension bracket, and the other end is connected to the pendulum; the measuring component includes an oil storage tank, a measuring piece and a support plate, the oil storage tank is provided with an oil storage cavity opening upward, the oil storage cavity is filled with lubricating oil, the oil storage tank is located directly below the suspension bracket, the pendulum is penetrated through the oil storage cavity and is located below the liquid level of the lubricating oil, the measuring piece includes a horizontal plate and a vertical plate, the vertical plate is connected to the horizontal plate and is perpendicular to the horizontal plate, the side wall of the vertical plate is provided with a first measuring ruler, the support plate is circumferentially arranged on the inner wall of the oil storage cavity and is located at the upper part of the oil storage cavity, and the horizontal plate is abutted against the support plate to support the measuring piece.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figure 1 The utility model provides a technical solution: a ship tilting test device.

[0024] Among them, the four corners of the bottom plate 1 are fixedly connected with columns 3, the top of the column 3 is fixedly connected with the top plate 2, a winder 4 is arranged at the bottom center of the top plate 2, a bracket 5 is arranged below the winder 4, a cycloid through hole 6 is opened at the bottom center of the bracket 5, a cycloid 7 is arranged at the center of the cycloid through hole 6, the top of the cycloid 7 is wound on the winder 4, a pendulum clock 11 is arranged at the bottom of the cycloid 7, a double-layer plywood 8 is arranged at the top center of the bottom plate 1, the pendulum clock 11 is arranged in the gap between the double-layer plywood 8, a visible window 9 is opened in the middle of the double-layer plywood 8, and scale lines 13 are arranged above and below the visible window 9.

[0025] In this embodiment, the bottom plate 1 supports the top plate 2 through four pillars 3, and the visual window 9 passes through two places of the double-layer plywood 8. Scale lines 13 are set at the upper and lower places of the visual window 9. The scale lines 13 are divergent long lines, which are scattered around the cycloid perforation 6 as the center, leaving lines above and below the visual window 9. The distance between each line is fixed, and the angle is determined according to the division ratio. The pendulum clock 11 is circular and embedded in the visual window 9. The top of the pendulum clock 11 is connected by the cycloid 7, and the cycloid 7 is wound on the winder 4. The winder 4 is set at the bottom of the top plate 2 to suspend the pendulum clock 11, and the cycloid 7 passes downward. The cycloid perforation 6 passes through the center of the bracket 5, and the visual window 9 is in an arc shape with the cycloid perforation 6 as the center of the arc. The bottom 1 is placed flat on the ground inside the ship. When the ship tilts, the bottom plate 1 fits the ground and the entire device also tilts. At this time, since the direction of gravity perpendicular to the pendulum 11 and the horizontal plane does not change, the direction pulled by the cycloid 7 is the same as the direction of gravity, so that the pendulum 11 slides in the visual window 9, pulling the cycloid 7 to adjust the angle with the bottom plate 1, aligning the position of the cycloid 7 with the corresponding position of the scale line 13, confirming the degree of the aligned scale line 13, and thus determining the tilt angle at this time.

[0026] A pressing plate countersunk hole 10 is provided at the center of the visual window 9 , a limiting plate 12 is provided at the center of the pressing plate countersunk hole 10 , and a through hole is provided at the center of the pendulum clock 11 .

[0027] In this embodiment, the pendulum 11 is stabilized at the center position of the visual window 9, the center line of the perforation in the center of the pendulum 11 is aligned with the center line of the pressure plate countersunk hole 10, and the pendulum 11 is locked in the visual window 9 by passing a screw through the hole. In this way, when the external ship shakes again, the pendulum 11 and the cycloid 7 will no longer shake. When the device does not need to work, the pendulum 11 is fixed to reduce the wear caused by the shaking of the cycloid 7, thereby extending the service life of the cycloid 7. At the same time, fixing the pendulum 11 can also facilitate the transportation of the device.

[0028] Wherein, handles 14 are provided through the left and right sides of the top plate 2 .

[0029] In this embodiment, the handles 14 are on the left and right sides, and the operator can lift the top plate 2 by holding the handles 14 to carry the device. The pendulum clock 11 is locked before carrying to prevent the pendulum clock 11 from shaking and causing collision during the transportation process.

[0030] The visible window 9 is provided with rounded corners in the direction of the gap, and the rounded corners fit the surface of the pendulum clock 11 .

[0031] In this embodiment, the four rounded corners fit the pendulum 11, and the pendulum 11 is clamped between the double-layer plywood 8. The smaller gap can reduce the force of the pendulum 11 hitting the double-layer plywood 8, thereby extending the service life.

[0032] The cycloid 7 is made of nylon rope.

[0033] In this embodiment, multiple strands of nylon material are selected to increase the strength of the cycloid 7 and extend the service life of the cycloid 7 .

[0034] The reel 4 can rotate to reel in or unwind the cycloid 7 .

[0035] In this embodiment, when the pendulum clock 11 is locked, the winder 4 is slightly rotated to lengthen the cycloid 7 , so that the entire cycloid 7 is relaxed and no longer in a tight state, thereby better extending the life of the cycloid 7 .

[0036] Working principle: Place the device on the inner plane of the ship, with the bottom plate 1 fitting the plane. When the ship tilts, since the direction of gravity perpendicular to the pendulum 11 and the horizontal plane will not change, the direction pulled by the cycloid 7 is the same as the direction of gravity. The pendulum 11 slides in the visible window 9, thereby pulling the cycloid 7 to adjust the angle with the bottom plate 1, aligning the position of the cycloid 7 with the corresponding position of the scale line 13, confirming the degree of the aligned scale line 13, and thus determining the tilt angle at this time. After the measurement is completed, stabilize the pendulum 11 at the center position of the visible window 9, and lock the pendulum 11 in the visible window 9 by screwing through the hole. In this way, when the external ship shakes again, the pendulum 11 and the cycloid 7 will not shake with it. When the device does not need to work, the pendulum 11 is fixed to reduce the wear caused by the shaking of the cycloid 7, thereby extending the service life of the cycloid 7. The operator can easily carry the device by holding the handle 14.
