Technical Field

[0001] The present invention relates to a device and method for measuring the weight and gravity center in air and underwater, and more particularly to an assembled underwater weight and gravity center measuring device suitable for any curved surface body. Background Art

[0002] To determine the actual weight and center of gravity of any curved surface, it is necessary to conduct tests to measure its weight and center of gravity in air and underwater. In existing technology, test fixtures are often constructed temporarily based on the principle of measuring the center of gravity using a three-point support method.

[0003] Existing testing fixtures often use a three-point support method to measure the center of gravity, requiring temporary construction. However, due to the complexity of installing test equipment in ordinary water tanks, the lack of lifting equipment to transport the test objects, and the lack of specialized equipment or devices, measuring weight and center of gravity in air and underwater presents significant challenges. Furthermore, replacing the test objects and readjusting the fixtures during batch measurements is time-consuming and labor-intensive. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an assembled underwater weight and center of gravity measuring device suitable for arbitrary curved surface bodies, which can solve the problem of difficulty in measuring the weight and center of gravity of arbitrary curved surface bodies in the air and underwater.

[0005] The technical solution adopted by the present invention to solve the technical problem is: constructing an assembled underwater weight and gravity center measuring device suitable for any curved surface, including a movable water tank, a weighing unit and an anti-overturning connecting rod;

[0006] The movable water tank is arranged on the ground to store water safely;

[0007] The weighing units include a plurality of weighing units, and adjacent weighing units are connected via an anti-overturning connecting rod. The weighing units are used to support the object to be measured and measure the weight of the object to be measured.

[0008] According to the above solution, the movable water tank includes 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.

[0009] According to the above scheme, the weighing unit includes an outer frame, an anti-overturning device connection point, a height adjustment device and a liftable weighing module; the outer frame includes a bottom bracket, an oblique bracket and a center bracket, the bottom bracket includes four, the bottom bracket is arranged at the bottom of the center bracket, the angle between adjacent bottom brackets is 90°, the top end of the oblique bracket is arranged at the top of the center bracket, and the bottom end of the oblique bracket is arranged at the end of the bottom bracket; the two ends of the anti-overturning connecting rod are clamped on the anti-overturning device connection point; the center bracket is a cylindrical structure, the height adjustment device is arranged in the cylinder of the center bracket, and the liftable weighing module is arranged on the top of the height adjustment device.

[0010] According to the above solution, anti-overturning device connection points are provided at the middle positions of the bottom bracket and the oblique bracket.

[0011] According to the above solution, the liftable weighing module can slide up and down in the cylinder of the outer frame.

[0012] According to the above solution, the anti-overturning connecting rod can be telescopically adjusted in length and is provided with a length locking device.

[0013] According to the above solution, when one end of the anti-overturning connecting rod is connected to the connection point of the anti-overturning device, it can rotate along the connection point of the anti-overturning device.

[0014] The assembled underwater weight and center of gravity measuring device applicable to any curved surface of the present invention has the following beneficial effects:

[0015] 1. The present invention uses a movable water tank to store water, which can be used to quickly measure the weight center of gravity in the air and underwater in a general factory environment. First, lay a waterproof cloth, build the test equipment on the waterproof cloth and place the object to be measured, then build the movable water tank. After completing the weight center of gravity measurement in the air, water is added to complete the underwater measurement.

[0016] 2. The present invention allows for free selection of the measurement point location for the center of gravity, with the option of three-point or four-point measurement. Weighing units are arranged at the measurement points, and the relative positions of the weighing units are fixed with anti-overturning connecting rods. This significantly saves time and labor costs when batch testing curved surfaces of different sizes. Furthermore, the device is assembled, making it easy to store.

[0017] 3. In the present invention, multiple weighing units are connected by anti-overturning connecting rods to form a frame structure. When a heavier object is lifted or placed, the measuring device can be prevented from overturning, thereby ensuring the safety of personnel and property. The weighing module can adjust the height position of the measuring point to adapt to the curved surface position of the object being measured, and the posture of the object being measured can be adjusted by lifting or lowering the measuring point.

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 present invention is an assembled underwater weight and center of gravity measuring device suitable for any curved surface, comprising a movable water tank 1, weighing units 2, and an anti-overturning connecting rod 3. The movable water tank 1 is set on the ground to safely store water; the weighing units 2 include a plurality of weighing units 2, adjacent weighing units 2 are connected by an anti-overturning connecting rod 3, and the weighing units 2 are used to support the object to be measured and measure the weight of the object to be measured. The weighing units 2 are fixed in relative position by the anti-overturning connecting rod 3, 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 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 includes 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] An anti-overturning device connection point 22 is provided at the middle position of the bottom bracket 21a and the oblique bracket 21b. 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-overturning connecting rod 3 can be telescopically adjusted in length and is provided with a length locking device. When one end of the anti-overturning connecting rod 3 is connected to the anti-overturning device connection point 22, it can be rotated along the anti-overturning device connection point 22. Any two weighing units 2 can be connected by the anti-overturning connecting rod 3. When the length of the anti-overturning connecting rod 3 is locked, the relative positions of 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-tilt connecting rods 3 is placed in a movable water tank 1. Without water, the center of gravity of the object under test is measured in air. After water is added, the center of gravity of the object under test can be measured underwater. After the posture is adjusted, the relative position of the weighing units and the object under test is measured. The weighing module then measures the readings and calculates the center of gravity in air. After water is added to submerge the object under test, the weighing module measures the readings again and calculates the center of gravity underwater.

[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 methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
