DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0020] Embodiment 1

[0021] Reference Figures 1-4The utility model discloses a ship stability measuring device, including installation platform 1, the fixed connection of installation platform 1 has ink box 2, be provided with the water absorption sponge 3 in ink box 2, the bottom surface fixed connection of water absorption sponge 3 has the pendant 4, the bottom fixed connection of pendant 4 has plumb bob 5, the fixed connection of installation platform 1 has fixed plate 6, the side fixed connection of fixed plate 6 has spring 7, the side fixed connection of spring 7 has moving plate 8, the side fixed connection of moving plate 8 has rack 9, the fixed connection of installation platform 1 has L type board 10, and the rotary connection of L type board 10 has missing tooth gear 11, and missing tooth gear 11 and rack 9 are mutually engaged, and the side fixed connection of moving plate 8 has the top rope board 12 of 12;

[0022] The side symmetrical fixed connection of fixed plate 6 has a plurality of limit rods 19, and moving plate 8 is slidably connected with the limit rods 19, and the side fixed connection of missing tooth gear 11 has a rotating rod 17, the rotating rod 17 penetrates through the L-shaped plate 10, and the end of the rotating rod 17 is fixedly connected with a handle 16.

[0023] The operation process of the embodiment is as follows: the installation platform 1 is fixed on the surface of the ship plate by bolts and kept in a vertical state with the ship body, when measuring the stability of the ship, the counterweight of a fixed weight is moved to one side of the ship body, at this time, the ship is tilted due to the influence of the counterweight, when the ship body is completely stable, the tilt angle of the ship body is measured, at this time, the ship body is tilted in the water, thereby driving the installation platform 1 to change the angle with the horizontal line, but the plumb bob 5 at the bottom of the pendant 4 always pulls the pendant 4 to keep vertical with the horizontal line, by measuring the angle change between the pendant 4 and the installation platform 1, it can be concluded that under the specific weight of the counterweight, how many degrees of tilt will occur to the ship body;

[0024] The ink in the ink box 2 continues to slowly soak downward along the water absorption sponge 3, so that the surface of the pendant 4 is full of ink during the measurement stage, after the ship body is completely stable, the missing tooth gear 11 is rotated, the missing tooth gear 11 drives the rack 9 to move and compresses the spring 7, the movement of the rack 9 drives the top rope board 12 to move and change the position of the pendant 4, when the teeth on the missing tooth gear 11 and the rack 9 are disengaged, the moving plate 8 is quickly slid on the limit rods 19 towards the position of the pendant 4 under the influence of the reset of the spring 7, the initial position of the top rope board 12 is not in contact with the pendant 4, and it keeps parallel with the fixed frame, at this time, the angle between the fixed frame and the pendant 4 changes due to the tilt of the ship body, the top rope board 12 quickly contacts with the pendant 4, the ink on the pendant 4 is printed on the jacking plate, thereby the measurement results of this stability can be directly recorded, which is more convenient for the user to calculate the stability of the ship in the future.

[0025] Embodiment 2

[0026] Because the different weights need to incline the ship body during the test, multiple measurements need to be taken, and the ink stamp on the lifting rope 4 can only record on the top rope plate 12 once, thereby reducing the practicability of the device. Figures 1-4 On the basis of the first embodiment, the top rope plate 12 is fixedly connected with a replacement seat 13, the two opposite sides of the replacement seat 13 are provided with sliding grooves 15, and the replacement seat 13 is slidably connected with a display plate 14, the display plate 14 is provided with a scale line, and the two opposite sides of the display plate 14 are fixedly connected with sliding blocks which are inserted and matched with the sliding grooves 15.

[0027] The side of the missing gear 11 is fixedly connected with a rotating rod 17 which penetrates the L-shaped plate 10, the end of the rotating rod 17 is fixedly connected with a handle 16, the surface of the mounting table 1 is fixedly connected with a measuring plate 18, and the center line of the display plate 14 is parallel to the lifting rope 4.

[0028] The operation process of the embodiment is as follows: when the top rope plate 12 moves towards the lifting rope 4 quickly, the replacement seat 13 moves, the display plate 14 is arranged on the replacement seat 13, and the display plate 14 is provided with a scale line, at this time, because the ship body inclines, the angle between the lifting rope 4 and the display plate 14 changes, after the display plate 14 is attached to the lifting rope 4, the ink stamp on the lifting rope 4 is on the scale line, and the inclination angle during the measurement can be more clearly reflected.

[0029] When the detection is re-performed, the weight or position of the weight on the ship body changes, at this time, the inclination angle of the ship body changes, the recorded display plate 14 is removed from the replacement seat 13 and saved, the new display plate 14 is inserted into the replacement seat 13, and the next stability measurement can be re-performed, when used, the measurer can also observe whether the lifting rope 4 and the fixing frame remain in the vertical state according to the scale line on the measuring plate 18, and the test result can be affected by the installation deviation of the fixing table.

[0030] The above is only a preferred specific embodiment of the utility model, but the protection scope of the utility model is not limited to this, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, and all of them should be covered in the protection scope of the utility model.
