[0036] The specific implementation of this embodiment is described below with reference to the accompanying drawings.

[0037] The displacement detection assembly 1 comprises three groups of displacement detection components 1, each group of displacement detection components 1 is evenly arranged around the annular container 2 with the center of the circle as the base point, and the displacement detection assembly 1 is provided with a track 3, a slider 4 is slidably provided at one end of the track 3, a vertical support beam 5 is installed on the slider 4, a horizontal support beam 6 is slidably provided on the vertical support beam 5, a top probe 61 is provided on the horizontal support beam 6, a vertical beam 7 is installed at the end of the horizontal support beam 6, a small-diameter probe 71 is installed on the vertical plate, a top block 72 is installed on the right side of the small-diameter probe 71, a top column 73 is installed at the lower end of the top block 72, and the end of the top column 73 is installed in the locking block 75 through a spring 74, a support rod 8 is slidably installed between the top block 72 and the vertical support beam 5 through the slider 4, a large-diameter probe 81 is installed on the support rod 8, and a top probe 61. The small-diameter probe 71 and the large-diameter probe 81 are cylindrical metal rods, and the ends of the metal rods can be polished into a conical shape. The top probe 61, the small-diameter probe 71 and the large-diameter probe 81 simultaneously abut the strain gauge 10 set on the side wall of the annular container 2. A circular hole is opened on the support rod 8, and the large-diameter probe 81 is placed in the circular hole and then fixed in the circular hole by welding. A circular hole is opened on the transverse support beam 6, and the top probe 61 is placed in the circular hole and then fixed in the circular hole by welding. A circular hole is opened on the transverse support beam 6, and the large-diameter probe 81 is placed in the circular hole and then the small-diameter probe 71 is fixed in the circular hole by welding. The strain gauge abutted against the annular container 2 can be a resistance strain gauge with an existing model of BF120.

[0038] Fixing holes 31 are provided at both ends of the track 3 , and the track 3 is fixedly mounted on the orifice plate 9 through the fixing holes 31 . The orifice plate 9 can be an existing breadboard, and the track 3 can be mounted corresponding to different positions.

[0039] A flat plate 62 is installed at the end of the top probe 61, and the top probe 61 is abutted against the side wall of the annular container 2 through the flat plate 62. The probe head is designed as a flat plate 62 and a probe structure. This is because the surface of the annular container 2 is concave or convex. During the container pressurization process, the cross-section of the annular container 2 will change. In order to enable the probe to be evenly pressurized, the probe head adopts a flat plate 62 and a probe-shaped structure.

[0040] Reference Figure 4 A flat plate 62 is installed at the end of the large-diameter probe 81 , and the large-diameter probe 81 abuts against the side wall of the annular container 2 through the flat plate 62 .

[0041] The top probe 61 and the small-diameter probe 71 are 90° apart in the circumferential direction with the center of the cross-section of the annular container 2 as the base point, and the small-diameter probe 71 and the small-diameter probe 71 are 180° apart in the circumferential direction with the center of the cross-section of the annular container 2 as the base point. This can realize the accurate detection of the displacement of the three positions of the inner ring circle, the outer ring circle and the top of the ring surface of the annular container 2 during the filling process, without being affected by the overall size of the annular container 2 and the circular cross-section.

[0042] Each group of detection components is circumferentially spaced 120° apart with the center of the annular container 2 as a base point, ensuring the detection of displacement changes in multiple areas of the annular container 2.

[0043] The cross-section of the track 3 is convex, and a concave groove 41 is provided in the slider 4. The slider 4 is slidably installed on the track 3 through the concave groove 41. The sliding locking block 75 is provided with a concave groove 41. The locking block 75 is slidably installed on the track 3 through the concave groove 41.

[0044] Reference Figure 5 and Figure 6 The slider 4 and the locking block 75 can be fixed to the rail 3 by the first locking bolt 42. The first locking bolt 42 passes through the slider 4 or the locking block 75. The end of the first locking bolt 42 contacts the side wall of the rail 3. The first locking bolt 42 presses the slider 4 or the locking block 75 onto the rail 3 to achieve fixation. When adjustment is required, loosen the first locking bolt 42. The end of the first locking bolt 42 no longer contacts the side wall of the rail 3. At this time, the slider 4 or the locking block 75 can move along the rail 3.

[0045] Reference Figure 1 、 Figure 7 and Figure 8 The vertical support beam 5 is provided with a T-shaped slot 51, and a rectangular slot 53 is provided on the side wall of the vertical support beam 5 and at the bottom of the T-shaped slot 51. A T-shaped fixing plate 52 is fixed at the end of the transverse support beam 6 and at both side walls of the transverse support beam 6 by installing bolts 54. Threaded holes are provided on the T-shaped fixing plate 52 and the transverse support beam 6. The installing bolts 54 penetrate the T-shaped fixing plate 52 and the transverse support beam 6 at the same time and fix the T-shaped fixing plate 52 and the transverse support beam 6 with nuts. A threaded hole 55 is provided at the end of the transverse support beam 6, and a second locking bolt 56 is provided through the rectangular slot 51 and the threaded hole 55. The second locking bolt 56 is loosened when the height of the transverse support beam 6 needs to be adjusted, and the second locking bolt 56 is tightened when it needs to be fixed. At this time, the nut at the end of the second locking bolt 56 is against the side wall of the vertical support beam 5.

[0046] A mounting groove 76 is provided in the locking block 75, and a spring 74 is fixedly installed at the end of the top column 73. The end of the spring 74 is fixedly installed on the bottom wall of the mounting groove 76. The top column 73 of the locking block 75 can press the top block 72 with a certain compression force of the spring 74. The top block 72 restricts the movement of the annular container 2. The force generated by the spring 74 in the locking block 75 should be moderate. The cross-sectional shape of the annular container 2 changes during the pressurization process. Under the action of the spring 74, the top block 72 always presses against the inner surface of the annular container 2.

[0047] The testing process of this utility model is as follows:

[0048] The track 3 is fixed on the orifice plate 9 through the fixing hole 31. The orifice plate 9 can be an existing breadboard. The track 3 and the orifice plate 9 are fixed by bolts. There are fixing holes 31 on the track 3. The fixed position of the track 3 can be adjusted according to the overall size of the annular container 2. The three displacement detection components 1 are distributed on the breadboard at an angle of 120° to each other. The annular container 2 is placed on the track 3 of the three detection devices. The locking block 75 of the annular container 2 presses the top block 72 along the track 3 with a certain force to fix the annular container 2. The position of the position probe is adjusted so that the probe head touches the surface of the annular container 2 and returns to zero. The annular container 2 is pressed. After the annular container 2 expands under pressure, it squeezes the probe. The probe squeezes the strain gauge 10. The strain gauge 10 records the pressure change and the probe records the displacement change.

[0049] Although the specific implementation methods of the present invention are described in conjunction with the accompanying drawings, this does not limit the scope of protection of the present invention. Those skilled in the art should understand that on the basis of the technical solution of the present invention, various modifications or variations that can be made by those skilled in the art without creative work are still within the scope of protection of the present invention.
