[0016] The beneficial effects of the present invention are as follows: a cavity is set on the outer shell to simulate an oil well, and a high-pressure connection device connected to the inside of the cavity is used to penetrate a high-pressure medium into the cavity to simulate the actual working conditions in the well. The sliding sealing structures set at both ends of the cavity are used to seal the two ends of the cavity when the oil pipe and the oil pipe coupling are inserted into the cavity, so as to ensure the high pressure in the cavity, thereby simulating the actual working conditions in the well, wherein the setting of the sliding sealing structure enables it to seal the cavity when adapting to the angle change of the oil pipe, so as to ensure the high-pressure working conditions in the cavity of the outer shell.

The two installation and adjustment mechanisms are driven by the driving mechanism to move horizontally. Since the oil pipe is fixed on the installation and adjustment mechanism, it can drive the oil pipe to move horizontally in the cavity of the outer shell, realizing the simulation of the lifting and lowering movement of the oil pipe in the well.

When the coupling on the oil pipe passes through the coupling detection unit, the coupling detection unit recognizes the coupling and takes a photo of the coupling, and transmits the image to the industrial control computer. The industrial control computer calculates and feedbacks the wear of the coupling, and calculates and feedbacks the eccentric coordinates of the coupling through coordinate drawing, so as to realize the measurement of the wear and eccentricity of the coupling. After that, the inclination angle of the oil pipe can be adjusted again through the installation adjustment mechanism, and the experiment is carried out again to obtain test data with different inclination angles.

DETAILED DESCRIPTION

[0029] Specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0030] Reference Figures 1 to 8 The present invention provides an embodiment of a contactless coupling automatic detection simulation experimental device.

[0031] A contactless coupling automatic detection simulation experiment device comprises a base 1, on which an outer shell 2 and a power system are arranged. The outer shell 2 is used to simulate an oil well, and the power system is used to simulate the movement state of an oil pipe in the oil well.

[0032] The outer shell 2 is fixed on the upper side of the base 1 through a mounting frame. The outer shell 2 has a cavity 21 with two ends passing through the outside and a high-pressure connection device 3 connected to the inside of the cavity 21. The high-pressure fluid is infiltrated into the cavity 21 through the high-pressure connection device 3 to make the inside reach 70MPa, simulating the working conditions in the well. The axis of the cavity 21 is arranged parallel to the axis of the base 1. Flanges are provided on both sides of the outer shell. Through the setting of the flange, the device can be connected in series with other tools and installed in actual work. The actual working conditions can be simulated before going down the well to test the oil pipe coupling to ensure that the oil pipe coupling can operate normally; it can also cooperate with the oil pipe and the ball ring part 412 to limit the inclination angle of the oil pipe so that it is controlled within 0 to 3° to simulate the rotation angle of the oil pipe in the actual working conditions.

[0033] The high-voltage connection device 3 comprises a high-voltage joint and a combined sealing gasket. A mounting hole is arranged on the outer shell 2, and the high-voltage joint and the combined sealing gasket are mounted in cooperation with the mounting hole.

[0034] The two ends of the cavity 21 are provided with a sliding sealing structure 4, part of the outer side of the sliding sealing structure 4 cooperates with the inner wall of the cavity 21, and the inner side of the sliding sealing structure 4 cooperates with the outer wall of the oil pipe, and is used to seal the two ends of the cavity 21 when the oil pipe and the oil pipe coupling are inserted into the cavity 21, so as to ensure the high pressure in the cavity 21, thereby simulating the actual well working conditions. Among them, the setting of the sliding sealing structure 4 enables it to seal the cavity 21 when adapting to the angle change of the oil pipe, so as to ensure the high pressure working condition in the cavity 21 of the outer shell 2.

[0035] At least one set of coupling detection units is also provided in the circumferential direction of the outer shell 2, and the coupling detection units are connected to the industrial control computer signal; the coupling detection units realize contactless photography of the couplings through image recognition and infrared technology, and input the data into the industrial control computer to analyze the wear and eccentricity of the couplings.

[0036] The power system is arranged on the base 1, and includes a mounting adjustment mechanism 6 arranged on both sides of the outer shell 2 for adjusting the angle and height of the oil pipe and a driving mechanism for horizontal movement of the oil pipe. The two ends of the oil pipe are mounted and fixed by the two mounting adjustment mechanisms 6, and the inclination angle and height of the oil pipe can be adjusted by the two mounting adjustment mechanisms 6, so as to facilitate the simulation of different spatial conditions that may occur in the actual work of the oil pipe, and to enable the detection of couplings at various angles and heights. The two mounting adjustment mechanisms 6 are driven to move horizontally by the driving mechanism. Since the oil pipe is fixed on the mounting adjustment mechanism 6, the oil pipe can be driven to move horizontally in the cavity 21 of the outer shell 2, so as to simulate the lifting and lowering movement of the oil pipe in the well. Under actual working conditions, the oil pipe is connected by a coupling, that is, there are multiple couplings on the oil pipe. In this embodiment, for the convenience of explanation, one coupling is provided on the oil pipe.

[0037] By adopting the present invention, the working environment in the well can be simulated through the outer shell 2, the high-pressure connection device 3 and the sliding seal structure, and the inclination angle of the oil pipe can be adjusted through the installation adjustment mechanism 6 of the power system to simulate the rotation angle of the oil pipe in the actual working condition. The driving mechanism drives the installation adjustment mechanism 6 to move horizontally to simulate the lifting state of the oil pipe in the actual working condition. The coupling detection unit can take non-contact photos of the coupling and feed back to the industrial control computer to calculate the wear and eccentricity. When conducting theoretical research, the wear and eccentricity of the coupling can be experimentally studied, thereby providing a solution to the problem of high difficulty and low precision in detecting the coupling of the oil pipe.

[0038] In some embodiments, the driving mechanism includes a rotary motor 71, a screw 72 and a guide rod 73, the screw 72 is rotatably arranged on the base 1 and fixed to the output end of the rotary motor 71, the screw 72 is threadedly connected with a screw nut 74 that is slidably matched with the guide rod 73, and the mounting adjustment mechanism 6 is arranged on the screw nut 74. The axis of the screw 72 is arranged parallel to the axis of the base 1, so that the oil pipe can reciprocate along the axis direction of the cavity 21. In this way, two groups of screw nuts 74 are provided and located on both sides of the outer shell 2. When the rotating motor 71 rotates, the screw rod 72 is driven to rotate. Since the guide rod 73 and the screw nut 74 slide together to stop the screw nut 74 from rotating, the screw nut 74 makes reciprocating linear motion on the screw rod 72, driving the two mounting and adjusting mechanisms 6 provided on the screw nut 74 to make reciprocating linear motion on the screw rod 72, thereby driving the oil pipe fixed on the mounting and adjusting mechanism 6 to make reciprocating linear motion along the axial direction of the screw rod 72, that is, the oil pipe and the oil pipe coupling make horizontal movement in the cavity 21 of the outer shell 2, so as to realize the simulation of the lifting and lowering state of the oil pipe in the oil well.

[0039] In some embodiments, the installation adjustment mechanism 6 includes a ball-joint bracket 61, a ball-joint connecting rod 63 connected to the ball-joint bracket 61 through a ball-joint 62, an adjusting oil pipe clamp 64 for fixing the oil pipe is connected to the ball-joint connecting rod 63 through a thread, and a clamp 641 is fixed to the top of the adjusting oil pipe clamp 64. A thread is provided on the outer peripheral surface of the ball-joint connecting rod 63, and an internal thread is provided on the adjusting oil pipe clamp 64. The adjusting oil pipe clamp 64 is threadedly matched with the thread on the ball-joint connecting rod 63, and the height of the adjusting oil pipe clamp 64 can be adjusted, that is, the length of the adjusting oil pipe clamp 64 and the component of the ball-joint connecting rod 63 can be changed. The lower end of the ball-joint bracket 61 is fixed with a screw nut 74 to support the ball-joint connecting rod 63 and the adjusting oil pipe clamp 64. The ball-joint bracket 61 and the ball-joint connecting rod 63 are connected through the ball-joint 62, so that the ball-joint connecting rod 63 can be freely rotated relative to the ball-joint bracket 61, and the angle of the ball-joint connecting rod 63 can be freely adjusted. By adjusting the height of the oil pipe clamp 64 and the angle of the ball joint connecting rod 63, the two ends of the oil pipe are fixed on the adjusting oil pipe clamps 64 on both sides, so as to adjust the inclination angle of the oil pipe to simulate the rotation angle of the oil pipe in actual working conditions.

[0040] For ease of understanding, this embodiment is illustrated by way of example. Figure 1When the ball-joint connecting rod 63 on the left side rotates forward, the adjusting tubing clamp 64 is driven to deflect forward, and the ball-joint connecting rod 63 on the right side rotates backward, the adjusting tubing clamp 64 is driven to deflect backward. The axis projections of the tubing clamps on both sides form an angle. The length between the adjusting tubing clamp 64 and the ball-joint connecting rod 63 is adjusted to adapt to the installation of the tubing. Then, the two ends of the tubing are installed on the adjusting tubing clamp 64. At this time, an angle is formed between the axis of the tubing and the axis of the cavity 21, that is, the tubing forms an inclination angle in the cavity 21, so as to simulate different spatial conditions of the tubing in the well.

[0041] Furthermore, the ball-joint bracket 61 includes a connecting column 611 fixed to the screw nut 74, and a ball base 612 fixed to the upper end of the connecting column 611 and provided with a mounting cavity, and a threaded hole 613 is provided on the side wall of the ball base 612, and a bolt is connected to the inner thread of the threaded hole 613. At this time, the lower end of the connecting column 611 is fixed to the screw nut 74, and the mounting cavity of the ball base 612 is spherically matched with the ball-joint 62. When the offset angle of the ball-joint connecting rod 63 is determined, the bolt can be tightened in the threaded hole 613 and the ball-joint 62 can be squeezed, and the ball-joint 62 can be fixed by friction force to achieve the angle positioning of the ball-joint connecting rod 63, thereby ensuring that the two ends of the oil pipe will not rotate around the circumference of the cavity 21 after being fixed on the adjusting oil pipe clamp 64, so as to ensure the stability of the oil pipe during horizontal movement.

[0042] In some embodiments, the sliding seal structure 4 includes a packing cavity 41, the packing cavity 41 includes a main body 411 and a ball ring 412 provided at one end of the main body 411, the outer wall of the ball ring 412 contacts the inner wall of the cavity 21, a packing hole 413 is provided on the main body 411 and a packing 2 42 is provided in the main body 411, and a liquid seal ring 43 and a sealing gland 44 are provided at both ends of the inner side of the main body 411. The inner wall of the packing cavity 41 is sealed with the oil pipe, and the packing 2 42 is injected into the main body 411 of the packing cavity 41 through the packing hole 413 to seal it with the outer wall of the oil pipe, a liquid seal ring 43 is provided at one end of the packing cavity 41, and the other end is pressed by the sealing gland 44 to complete the seal with the oil pipe. The ball ring 412 is used to seal with the cavity wall of the cavity 21. Since the ball ring 412 and the inner wall of the cavity 21 are linearly sealed, further, an annular groove 4121 is provided on the outer wall of the ball ring 412, and a filler 1 4122 is provided in the annular groove 4121, wherein the outer peripheral wall of the filler 1 4122 is an arc-shaped structure, at this time, the seal can be improved by squeezing the filler 1 4122 to deform it. The ball ring 412 is a spherical cut-out part, and the outer diameter contacts the inner wall of the cavity 21, which ensures the sealing effect when the oil pipe is tilted.

In this way, the oil pipe coupling can be photographed synchronously at multiple angles.

[0045] The light-transmitting lens 23 is sealed by a sealing rubber ring 24 to ensure the sealing performance of the cavity 21 of the outer shell 2. Specifically, the outer shell 2 is symmetrically provided with at least one group of stepped holes 22 that penetrate the cavity 21 for installing the light-transmitting lens 23. In this embodiment, two groups of stepped holes 22 are stacked on the outer shell 2. The steps of the stepped holes 22 are provided with a sealing rubber ring 24 and a light-transmitting lens 23. The lens pressure cover 25 is fixed to the outer shell 2 and the inner end of the lens pressure cover 25 presses the light-transmitting lens 23. Preferably, the light-transmitting lens 23 is pressure-resistant glass. The sealing rubber ring 24 is a combined seal, which includes a sealing ring with the same outer diameter and an inner diameter of 40 mm and a sealing ring with an inner diameter of 35 mm. The end of the sealing ring with an inner diameter of 35 mm is placed on the step of the stepped hole 22, and then the sealing ring with an inner diameter of 40 mm is placed, and then the light-transmitting lens 23 is placed. The clearance between the light-transmitting lens 23 and the sealing ring with an inner diameter of 40 mm is matched. The lens pressure cover 25 is tightened with the outer shell 2 by bolts. The inner extending end of the lens pressure cover 25 squeezes the sealing rubber ring 24 to cause it to deform, thereby achieving sealing between the light-transmitting lens 23 and the stepped hole 22.
