DETAILED DESCRIPTION

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, the assembled underwater weight and center of gravity measuring device applicable to any curved surface body of the present invention comprises a movable water tank 1, a weighing unit 2 and an anti-overturning connecting rod 3. The movable water tank 1 is set on the ground to safely store water; the weighing unit 2 comprises a plurality of weighing units 2, and adjacent weighing units 2 are connected by an anti-overturning connecting rod 3, and the weighing unit 2 is used to support the object to be measured and measure the weight of the object to be measured. The weighing unit 2 uses the anti-overturning connecting rod 3 to fix the relative position, and the height position can be adjusted to support the object to be measured and measure the weight of the object to be measured; the anti-overturning connecting rod 3 is located between the weighing units 2, so as to connect the weighing units 2 in pairs, fix the relative position, and prevent the weighing units 2 from overturning.

[0026] The movable water tank 1 comprises a plurality of modular panels, and adjacent modular panels are fixedly connected to form a rectangular parallelepiped shape. A waterproof cloth is laid inside the movable water tank 1 .

[0027] The weighing unit 2 includes an outer frame 21, an anti-overturning device connection point 22, a height adjustment device 23 and a liftable weighing module 24; the outer frame 21 includes a bottom bracket 21a, an oblique bracket 21b and a center bracket 21c, the bottom bracket 21a includes four bottom brackets 21a, the bottom brackets 21a are arranged at the bottom of the center bracket 21c, the angle between adjacent bottom brackets 21a is 90°, the top end of the oblique bracket 21b is arranged at the top of the center bracket 21c, and the bottom end of the oblique bracket 21b is arranged at the end of the bottom bracket 21a; the two ends of the anti-overturning connecting rod 3 are clamped on the anti-overturning device connection point 22; the center bracket 21c is a cylindrical structure, the height adjustment device 23 is arranged in the cylinder of the center bracket 21c, and the liftable weighing module 24 is arranged on the top of the height adjustment device 23.

[0028] The middle positions of the bottom bracket 21a and the oblique bracket 21b are both provided with an anti-tipping device connection point 22. The liftable weighing module 24 can slide up and down in the cylinder of the outer frame 21. The height adjustment device 23 adjusts the height of the measuring point by lifting the liftable weighing module 24. The anti-tipping connecting rod 3 can adjust the length telescopically, and is provided with a length locking device. When one end of the anti-tipping connecting rod 3 is connected to the anti-tipping device connection point 22, it can rotate along the anti-tipping device connection point 22. Any two weighing units 2 can be connected by the anti-tipping connecting rod 3, and when the length of the anti-tipping connecting rod 3 is locked, the relative positions between multiple weighing units 2 can be fixed.

[0029] The measurement process of the present invention is as follows:

[0030] During measurement, a structure consisting of several weighing units 2 and anti-overturning connecting rods 3 is placed in a movable water tank 1. When water is not filled, the weight center of gravity of the object to be measured in the air is measured. After water is filled, the weight center of gravity of the object to be measured in the water can be measured. After the posture adjustment is completed, the relative position of the weighing unit and the object to be measured should be measured, and then the reading is measured by the weighing module to calculate the weight center of gravity in the air. After the object to be measured is filled with water and immersed, the reading can be measured again by the weighing module to calculate the underwater weight center of gravity.

[0031] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
