Specifically, the inclined cylindrical rigid body 2 has small holes at the upper and lower parts, according to the principle of a communicating vessel, the height of the liquid level inside the inclined cylindrical rigid body is the same as that of the liquid level of the closed container 1, the balloons 3 in the rigid body float on the liquid level, the inclined cylindrical rigid body 2 rotates around the fixed shaft 4 by the related operation device, the rotational inertia measuring device can measure corresponding rotational inertia values, when the liquid level is at different positions, the heights of the balloons 3 in the inclined cylindrical rigid body 2 are different, the measured rotational inertia values are different corresponding to different heights of the balloons 3, and the height of the liquid level can be accurately obtained by comparing data measured by the rotational inertia measuring device.

Example 2

Referring to fig. 1, the device for detecting the liquid level of the closed container based on the measurement of the moment of inertia comprises a closed container 1, wherein an inclined cylindrical rigid body 2 is arranged in the closed container 1, a balloon 3 is arranged in the inclined cylindrical rigid body 2, liquid with a certain height is arranged in the closed container 1, holes are formed in two ends of the inclined cylindrical rigid body 2, a fixed shaft 4 is welded at the bottom of the closed container 1, and the upper end of the fixed shaft 4 is connected with the inclined cylindrical rigid body 2.

Specifically, the inclined cylindrical rigid body 2 has small holes at the upper and lower parts, according to the principle of a communicating vessel, the height of the liquid level inside the inclined cylindrical rigid body is the same as that of the liquid level of the closed container 1, the balloons 3 in the rigid body float on the liquid level, the inclined cylindrical rigid body 2 rotates around the fixed shaft 4 by the related operation device, the rotational inertia measuring device can measure corresponding rotational inertia values, when the liquid level is at different positions, the heights of the balloons 3 in the inclined cylindrical rigid body 2 are different, the measured rotational inertia values are different corresponding to different heights of the balloons 3, and the height of the liquid level can be accurately obtained by comparing data measured by the rotational inertia measuring device.

Specifically, referring to fig. 2, the outer side of the oblique cylindrical rigid body 2 is a wedge-shaped structure, and a plurality of circular holes are formed in the outer side of the oblique cylindrical rigid body 2. When the inclined cylindrical rigid body 2 rotates in water, the water rotates not only with gravitational potential energy, but also with rotational potential energy and kinetic energy, the closer to the rotating shaft, the larger the rotational potential energy is, and the closer to the rotating shaft, the lower the relative gravitational potential energy is, so that the middle of the water can sink down when rotating. This can make the measurement inaccurate.

The external part of the rigid body in the rotating direction is of a wedge-shaped structure, so that the contact surface generated in the rotating process is small, the resistance is small, and the rotating water driven by the contact surface is reduced. The rotating outer side surface is provided with a plurality of round small holes, so that water flows through the left side surface and the right side surface and also passes through the small holes in the rotating process, and the rotating potential energy of the water is reduced. Thus, the measurement result can be more stably and accurately obtained.

Example 3

Referring to fig. 1, the device for detecting the liquid level of the closed container based on the measurement of the moment of inertia comprises a closed container 1, wherein an inclined cylindrical rigid body 2 is arranged in the closed container 1, a balloon 3 is arranged in the inclined cylindrical rigid body 2, liquid with a certain height is arranged in the closed container 1, holes are formed in two ends of the inclined cylindrical rigid body 2, a fixed shaft 4 is welded at the bottom of the closed container 1, and the upper end of the fixed shaft 4 is connected with the inclined cylindrical rigid body 2.

Specifically, the inclined cylindrical rigid body 2 has small holes at the upper and lower parts, according to the principle of a communicating vessel, the height of the liquid level inside the inclined cylindrical rigid body is the same as that of the liquid level of the closed container 1, the balloons 3 in the rigid body float on the liquid level, the inclined cylindrical rigid body 2 rotates around the fixed shaft 4 by the related operation device, the rotational inertia measuring device can measure corresponding rotational inertia values, when the liquid level is at different positions, the heights of the balloons 3 in the inclined cylindrical rigid body 2 are different, the measured rotational inertia values are different corresponding to different heights of the balloons 3, and the height of the liquid level can be accurately obtained by comparing data measured by the rotational inertia measuring device.

Specifically, referring to fig. 3, the balloon 3 is filled with a filler, and a hollow air cushion is disposed at the lower end of the balloon 3. During the rotation, the balloon 3 is tightly attached to the wall of the oblique cylindrical rigid body 2 due to inertia effect and does not change along with the change of the liquid level height because the balloon is too light. If the weight of the balloon 3 is increased, the balloon 3 is sunk in water, and the measurement is affected. The balloon 3 is filled, i.e. the mass is increased, and a hollow air cushion is arranged below the balloon 3, so that the hollow air cushion can not sink or cling to the wall of the device due to inertia, and the measurement is more stable.
