It should be noted that, in the absence of conflict, the embodiments of the present invention and the features therein can be combined with each other.

[0026] In the description, it should be noted that the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance. It should be noted that, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood broadly. For example, they can refer to fixed connections, removable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms based on specific circumstances.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0029] The detection mechanism for simulating the displacement of an actuating member under deep water conditions comprises a circular cover 1 and a tank body 2 with a round bottom. The function of the tank body 2 is to ensure the environmental pressure of the product in the tank.

[0030] The round bottom of the tank body 2 is fixedly connected to the mounting base 3, and a blind hole 31 with a thread is provided downwardly at the top of the mounting base 3. The top of the tank body 2 is provided with an edge 21, and a sealing groove 1 is provided on the top of the edge 21. A sealing ring 22 is installed in the sealing groove 1, and a plurality of threaded holes 23 are provided on the edge 21. The side wall of the tank body 2 is provided with an inner cavity pressure interface 24 and an action pressure interface 25 near the round bottom.

[0031] A light hole corresponding to the position of the threaded hole 23 is provided on the edge of the cover 1, and a mounting hole 11 is fixedly provided on the cover 1. The mounting hole 11 extending out of the top surface of the cover 1 is provided with a thread, and a sealing groove 2 is provided on the lower side of the thread of the mounting hole 11, and a sealing ring 2 12 is installed in the sealing groove 2.

[0032] A measuring stud 4 is installed in the mounting hole 11. The measuring stud 4 includes a first column 41, a threaded column 42 and a second column 43. The diameter of the threaded column 42 is larger than the maximum outer diameter of the first column 41 and the second column 43. The length of the first column 41 is larger than the length of the threaded portion of the mounting hole 11. The first column 41 is a square column. The cover 1 is fixedly provided with a mounting hole 2 13. A constant pressure valve is installed in the mounting hole 2 13.

[0033] A mounting hole three is provided on the side wall of the tank body 2 near the cover 1 , and an observation window 6 is fixed in the mounting hole three.

[0034] In embodiment 1, the second mounting hole 13 is welded to the cover 1, and the gas in the tank body 2 is discharged during the water adding process. After the gas is discharged, a constant pressure valve is installed to ensure that the measuring stud 4 maintains a constant test pressure inside the tank body 2 during the measurement process when it is screwed into the tank body 2.

[0035] The mounting hole 11 is welded to the cover 1, and the measuring stud 4 is screwed into the tank body 2. After confirming through the observation window 6 that the second column 43 contacts the actuating part, the displacement of the second column 43 outside the tank body 2 is measured to obtain the actuating stroke of the actuating part.

[0036] A handle 14 is provided on the top surface of the cover 1. In this embodiment, 8 threaded holes 23 are provided and are evenly distributed. It should be noted that during actual operation, the observation window 6 may be too close to the cover 1. At this time, the edge 21 of the can body 2 is not a complete circle, and the position of the observation window 6 will be vacant. However, the sealing ring 22 is still complete, that is, the sealing groove is still a complete circle.

[0037] The observation window 6 is circular and includes a window frame 61, organic glass 62 and a pressure ring 63. The window frame 61 is welded in the mounting hole three and a portion thereof extends out of the tank body 2. The organic glass 62 is fixed on the side of the window frame 61 away from the tank body 2. A sealing structure 64 is provided at the position where the organic glass 62 and the window frame 61 are fixed. The portion of the window frame 61 extending out of the outside of the tank body 2 is provided with an internal thread. The pressure ring 63 is a hollow ring, with an external thread provided on the outer wall at one end and a regular hexagonal cross-section on the outer wall at the other end.

[0038] A stick-shaped protrusion 32 is provided on the top of the mounting seat 3 , and the stick-shaped protrusion 32 is a detachable pin.

[0039] The operating principle is as follows: During use, the actuator is placed inside the tank body 2 and fixed to the mounting base 3 using screws and pins. The actuator drive port is connected to the operating pressure port 25 via a pipe. The cover 1 is then installed and sealed to the tank body 2. It is important to ensure that the line connecting the observation window 6 and the center of the measuring stud 4 passes through the center line of the tank body 2 when sealing the cover 1 and the tank body 2. This is for optimal observation.

[0040] According to the test pressure required, a corresponding constant pressure valve is installed on the second mounting hole 13. The action pressure interface 25 is connected to the external air source, and the inner cavity pressure interface 24 is connected to the external hydraulic source. The tank body 2 is pressurized through the inner cavity pressure interface 24.

[0041] At this point, the measuring stud 4 is screwed in for the first time to measure the position of the actuating member before actuation (specifically, the length of the first stud 41 extending beyond the mounting hole 11 is measured using a measuring instrument). After this measurement, the second stud 43 of the measuring stud 4 is retracted into the cover 1. The actuating member is then actuated by the air source from the actuating pressure port 25. The measuring stud 4 is then screwed in again to measure the actuating member after actuation. While the measuring stud 4 is measuring and the actuating member is actuating, the constant pressure valve maintains a constant pressure within the tank 2. The pressure is then released to complete the actuating member position measurement.

[0042] In the second embodiment, two observation windows 6 are provided on the side wall of the tank body 2 near the cover 1 and are installed at the same level. One observation window 6 is specifically used to observe the operating parts, and the other observation window 6 is used to provide light when the vision is poor.

[0043] The utility model is characterized by:

[0044] The main feature is that the pressure inside the tank body 2 is increased through the inner cavity pressure interface 24, and the action pressure interface 25 drives the action part to move. The constant pressure valve ensures that the action part moves and the pressure of the tank body 2 remains unchanged during the measurement process of the measuring stud 4.

[0045] This structural measurement method is to accurately measure the displacement of the actuating member before and after the actuation by combining the observation window 6 and the measuring stud 4.

[0046] The above description is only a specific embodiment of the present invention, which enables those skilled in the art to understand or implement the present invention. Although detailed descriptions have been made with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents; and such modifications or replacements do not deviate from the essence of the corresponding technical solutions within the scope of the technical solutions of the embodiments, and they should all be covered by the scope of protection of the claims.
