[0032] In some feasible embodiments, the sliding column 1 is a cylinder made of rigid material, and the liquid level float 2 is a hollow ball. It needs to bear a large pressure in the pressure vessel, and the liquid level float 2 should be made of a material with greater strength. The ranging tube 3 is a circular tube and is installed at the upper end of the pressure vessel for installing the ranging sensor 4. The ranging sensor 4 can be optionally a laser rangefinder.

[0033] As a specific implementation of a pressure vessel internal liquid level observation device provided in the application, please refer to Figure 2 One end of the distance measuring tube 3 located in the pressure vessel is a closed end, and the closed end is made of glass.

[0034] In general, by setting The distance measuring tube 3 with a closed end allows the distance measuring sensor 4 to be located outside the pressure vessel, which facilitates the maintenance and replacement of the distance measuring sensor 4. When the pressure vessel is in working condition, the maintenance and replacement can also be carried out under the condition of complying with the safe operation of the pressure vessel.

A pipe cap 306 is installed on the upper end of the tube body 303 for sealing the distance measuring sensor 4. The limiting groove 301 is a plurality of rectangular grooves opened along the axial direction on the inner side of the distance measuring tube 3, and the rectangular grooves are arranged in a circular array. A rectangular block is arranged on the outer side of the limiting ring 302, and the rectangular block is correspondingly slidably installed in the rectangular groove. In order to facilitate the installation of the distance measuring sensor 4, a spring is arranged between the end of the distance measuring sensor 4 and the pipe cap 306.

[0043] In combination with specific usage scenarios, the liquid level float 2 is set with one side of the plane facing upward so that the plane faces the distance sensor 4, so that the signal of the distance sensor 4 forms effective feedback and reduces errors.
