This strain gauge tension sensor accurately reflects the longitudinal tensile force experienced by the instrument. Since the tension sensor is crucial to logging safety, it needs to be verified after a period of use to determine its proper functioning.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, components, or parts (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, components, or parts. Unless otherwise stated, "a plurality of" means two or more.

[0048] It is understandable that, due to the complex working environment downhole, when a tension sensor malfunctions, it cannot be determined whether the malfunction is due to the downhole environment or a fault in the sensor itself. Since the tension sensor is crucial for logging safety, it needs to be verified for proper functioning in a normal surface environment after a period of use. In existing technologies, verification of tension sensors in a normal surface environment typically only allows for positive value verification, not negative value verification. Therefore, this application provides a downhole tension sensor verification device to address this problem. The technical solution of this application will be further described below with reference to specific embodiments and accompanying drawings.

[0049] Please see Figure 1 This utility model provides a downhole tension sensor verification device 1, including a base 11, a top plate 12, a tension sensor 13, a movable frame assembly 14, and an adjusting member 15. The top plate 12 and the base 11 are spaced apart along a first direction. The tension sensor 13 is disposed between the base 11 and the top plate 12, and its first end is connected to the base 11. The movable frame assembly 14 is movably disposed between the base 11 and the top plate 12, and is connected to the second end of the tension sensor 13. The adjusting member 15 passes through the top plate 12 and is connected to the movable frame assembly 14. The adjusting member 15 can apply a positive direction (e.g., along the first direction) to the movable frame assembly 14. Figure 1 (as shown in the X direction) or the opposite direction (e.g.) Figure 1 The force (shown in the Y direction) is used to verify the positive or negative value of the tension sensor 13.

[0050] It should be noted that the first direction is a two-way direction, including the positive direction and the negative direction. The positive direction of the first direction is opposite to the negative direction of the first direction.

[0051] The distance between the base 11 and the top plate 12 in the first direction remains unchanged. The base 11 provides support for the tension sensor 13, and the top plate 12 provides support for the adjusting member 15.

[0052] The movement of the adjusting member 15 can drive the moving frame assembly 14 to move synchronously. When the moving frame assembly 14 is connected to the tension sensor 13, since the tension sensor 13 is fixed to the base 11, the adjusting member 15 has a tendency to move along the first direction, which causes the moving frame assembly 14 to also have a tendency to move synchronously. The moving tendency of the moving frame assembly 14 applies a force along the first direction to the tension sensor 13, thereby verifying the tension sensor 13 for positive or negative values.

[0053] For example, the first end of the tension sensor 13 is first fixed to the base 11, and the adjusting member 15 is connected to the moving frame assembly 14. The adjusting member 15 moves along the first direction to drive the moving frame assembly 14 to move synchronously, so that the moving frame assembly 14 gradually approaches the second end of the tension sensor 13 and connects the moving frame assembly 14 to the second end of the tension sensor 13.

[0054] When the moving frame assembly 14 is connected to the second end of the tension sensor 13, the adjusting member 15 has a tendency to move in the positive direction of the first direction, which drives the moving frame assembly 14 to move in the positive direction of the first direction simultaneously, so that the tension sensor 13 is subjected to a force in the positive direction of the first direction. When the tension sensor 13 is subjected to a force in the positive direction of the first direction, the positive value verification is completed.

[0055] Alternatively, the adjusting member 15 has a tendency to move in the negative direction of the first direction, which drives the moving frame assembly 14 to have a tendency to move in the negative direction of the first direction simultaneously, so that the tension sensor 13 receives a force in the negative direction of the first direction, and the negative value verification is completed when the tension sensor 13 receives a force in the negative direction of the first direction to reach a second preset force.

[0056] It should be noted that the above positive value verification and negative value verification are both primary verifications. After the tension sensor 13 is verified by the verification device 1 of this application embodiment for positive or negative value verification, it is then verified by other testing equipment to determine whether the tension sensor 13 is normal.

[0057] For example, after the tension sensor 13 is verified to be positive by this verification device 1, other testing equipment is used to test whether the tension sensor 13 is subjected to the first preset force. If the other testing equipment detects that the tension sensor 13 is subjected to the first preset force, it proves that the tension sensor 13 is normal. If the other testing equipment detects that the tension sensor 13 is not subjected to the first preset force, such as the tension sensor 13 is subjected to a force greater than or less than the first preset force, it proves that the tension sensor 13 is abnormal.

[0058] Similarly, after the tension sensor 13 is verified by the verification device 1 with a negative value, other testing equipment is used to test whether the tension sensor 13 is subjected to the second preset force. If the other testing equipment detects that the tension sensor 13 is subjected to the second preset force, it proves that the tension sensor 13 is normal. If the other testing equipment detects that the tension sensor 13 is not subjected to the second preset force, such as the tension sensor 13 is subjected to a force greater than or less than the second preset force, it proves that the tension sensor 13 is abnormal.

[0059] In this embodiment, the adjusting member 15 can apply a positive force or a negative force along the first direction to the tension sensor 13 through the moving frame assembly 14, thereby performing positive or negative value verification on the tension sensor 13, which improves the applicability of the verification of the tension sensor 13, while reducing the complexity of the device structure and the cost of verifying the tension sensor 13.

[0060] Please continue reading. Figure 1 In some embodiments, the adjusting member 15 is an adjusting screw, which passes through the top plate 12 and forms a threaded engagement with the top plate 12. The adjusting screw is connected to the movable frame assembly 14 and can rotate relative to the movable frame assembly 14. The adjusting screw can rotate in a first rotation direction or a second rotation direction to apply a force to the movable frame assembly 14 in the positive or negative direction of the first direction, wherein the first rotation direction is opposite to the second rotation direction.

[0061] The adjusting screw passes through the top plate 12, with one end of the adjusting screw located on the side of the top plate 12 away from the base 11, and the other end of the adjusting screw extending between the top plate 12 and the base 11 and connecting to the movable frame assembly 14. It should be noted that the adjusting screw and the movable assembly can rotate relative to each other to ensure that the rotation of the adjusting screw does not cause the movable assembly to rotate, but only causes the movable assembly to move along the first direction.

[0062] When the adjusting screw rotates along the first direction, it tends to move in the positive direction of the first direction, which drives the moving frame assembly 14 to move in the positive direction of the first direction simultaneously, so that the tension sensor 13 is subjected to the positive force of the first direction. When the tension sensor 13 is subjected to the positive force of the first direction, the positive value verification is completed.

[0063] When the adjusting screw rotates in the second direction, it tends to move in the negative direction of the first direction, which drives the moving frame assembly 14 to move in the negative direction of the first direction simultaneously, so that the tension sensor 13 receives a force in the negative direction of the first direction. When the tension sensor 13 receives a force in the negative direction of the first direction and the negative value verification is completed, the negative value verification is completed.

[0064] In this embodiment, the threaded structure of the adjusting screw can convert rotational motion into precise linear displacement, accurately controlling the magnitude of the force applied to the tension sensor 13 along the first direction, ensuring the verification accuracy of the tension sensor 13 in performing positive or negative value verification. Secondly, the screw engagement between the adjusting screw and the top plate 12 enables the adjusting screw to self-lock. That is, after the adjusting screw rotates along the first and second rotational directions to apply the first and second preset forces to the tension sensor 13, the rotational force applied to the adjusting screw can be removed. Because the adjusting screw achieves self-locking due to its thread, the tension sensor 13 remains subjected to the first and second preset forces. Furthermore, the force applied to the tension sensor 13 along the first direction by the adjusting screw can be gradually increased, avoiding sudden loads that could impact the tension sensor 13.

[0065] Please refer to the following: Figure 1 , Figure 2 and Figure 3 In some embodiments, a probe 133 is provided at the second end, and the moving frame assembly 14 is provided with a first through hole 1421 to avoid the probe 133. The probe 133 is electrically connected to the display device (not shown in the figure) via a connecting wire.

[0066] When the tension sensor 13 is subjected to a force in the positive direction of the first direction or a force in the opposite direction of the first direction, the force can be displayed on the display device, thereby allowing the tension sensor 13 to be intuitively obtained.

[0067] The probe 133 extends along the first direction. Due to its relatively long length, the probe 133 may interfere with the movable frame assembly 14. To solve this problem, in this embodiment, a first through hole 1421 is provided in the movable frame assembly 14. The probe 133 is avoided through the first through hole 1421, thus preventing interference between the probe 133 and the movable frame assembly 14 due to its long length.

[0068] Please refer to it again. Figure 1 and Figure 3 In some embodiments, the movable frame assembly 14 includes a first plate 141, a second plate 142, and a connecting rod 143. The first plate 141 is connected to an adjusting member 15. The second plate 142 is spaced apart from the first plate 141 along a first direction. The second plate 142 is connected to a second end and has a first through hole 1421. A probe 133 passes through the first through hole 1421 and extends between the first plate 141 and the second plate 142 to connect a connecting line. The connecting rod 143 connects the first plate and the second plate 142.

[0069] The second plate 142 is provided with a first through hole 1421. The probe 133 extends through the first through hole 1421 to connect the connecting wire. In order to avoid interference with the probe 133, in this embodiment, the first plate 141 and the second plate 142 are spaced apart along the first direction, so that the probe 133 passes through a part of the first through hole 1421 between the first plate 141 and the second plate 142, thereby preventing the first plate 141 from interfering with the probe 133.

[0070] The first plate 141 and the second plate 142 are connected by a connecting rod 143. At the same time, the first plate 141 is connected to the adjusting member 15. The first plate 141, the connecting member and the second plate 142 play the role of transmitting force, that is, the adjusting member 15 can apply force to the tension sensor 13 through the first plate 141, the connecting member and the second plate 142.

[0071] Please refer to it again. Figure 1 In some embodiments, the verification device 1 further includes a sleeve 161, one end of which is fitted and connected to a second end, and the other end of which passes through a first through hole 1421 and extends between a first plate 141 and a second plate 142. The end of the sleeve 161 located between the first plate 141 and the second plate 142 is connected to the second plate 142. The probe 133 passes through the sleeve 161 and extends between the first plate 141 and the second plate 142.

[0072] One end of the sleeve 161 is fitted onto and connected to the second end, and the other end is connected to the second plate 142, so that part of the probe 133 is located inside the sleeve 161. The sleeve 161 can avoid the probe 133 and protect the probe 133.

[0073] The sleeve 161 also serves to transmit force, meaning that the adjusting member 15 can apply force to the tension sensor 13 through the first plate 141, the connecting member, the second plate 142, and the sleeve 161.

[0074] Please refer to it again. Figure 1 and Figure 3 In some embodiments, the second end is provided with an external thread, and the end of the sleeve 161 used to connect the tension sensor 13 is provided with an internal thread, and the second end and the sleeve 161 are threadedly engaged. The sleeve 161 located at the end between the first plate 141 and the second plate 142 is provided with an external thread. The verification device also includes a nut 162, which is disposed between the first plate 141 and the second plate 142 and is threadedly engaged with the sleeve 161 to connect the sleeve 161 and the second plate 142.

[0075] The sleeve 161 is threaded to the second end of the tension sensor 13, which improves the stability of the connection between the sleeve 161 and the tension sensor 13, making the force transmitted from the sleeve 161 to the tension sensor 13 more stable. Similarly, the sleeve 161 and the nut 162 are threaded to connect to the second plate 142, which improves the stability of the connection between the sleeve 161 and the second plate 142, making the force transmitted from the second plate 142 to the sleeve 161 more stable.

[0076] Please refer to the following: Figure 4 and Figure 5 In some embodiments, the first end is provided with an internal thread. The verification device 1 also includes a first connector 17, one end of which is provided with an external thread and engages with the first end through a thread, and the other end of the first connector 17 is connected to the base 11.

[0077] The first connector 17 is threaded to the first end, which can improve the stability of the connection between the tension sensor 13 and the first connector 17.

[0078] Please see Figure 5 In some embodiments, the base 11 is provided with a second through hole 111, and the end of the first connector 17 away from the first end extends into the second through hole 111. The verification device 1 also includes a second connector 18, which connects the end of the first connector 17 extending into the second through hole 111 to the base 11.

[0079] The base 11 is provided with a second through hole 111 to avoid the end of the first connector 17 that is far away from the tension sensor 13, thus preventing the verification device 1 from being too long in the first direction. By connecting the end of the first connector 17 that extends into the second through hole 111 to the base 11 through the second connector 18, the tension sensor 13 can be fixed to the base 11.

[0080] Please continue reading. Figure 5 In some embodiments, the base 11 has a first side surface 112 and a second side surface 113 facing away from each other. The first side surface 112 and the second side surface 113 are respectively provided with a first screw hole (not shown in the figure) and a second screw hole (not shown in the figure) arranged along a second direction and coaxially connected. The first screw hole and the second screw hole are both connected to a second through hole 111. The end of the first connector 17 that extends into the through hole is provided with a connecting hole (not shown in the figure) coaxial with the first screw hole. The second direction (e.g. Figure 5 (As shown in the Z-direction) Perpendicular to the first direction. The second connecting member 18 is a fixing screw, which is threaded into the first screw hole and the second screw hole and passes through the connecting hole.

[0081] The first screw hole and the second screw hole are both connected to the second through hole 111 and are coaxial. The end of the first connector 17 away from the tension sensor 13 extends into the second through hole 111 and is provided with a connecting hole. The connecting hole is coaxial with the first screw hole and the second screw hole and the axial direction is parallel to the second direction. The fixing screw can pass through the first screw hole, the connecting hole and the second screw hole at the same time, and the fixing screw is threaded to at least the first screw hole and the second screw hole, so that the first fixing screw is connected to the base 11. At the same time, the fixing screw passes through the connecting hole and is connected to the first connector 17, thereby fixing the tension sensor 13 to the base 11.

[0082] It is understood that the connecting hole can be internally threaded and connected to the fixing screw, or it can be other types of holes, which are not limited here.

[0083] Please refer to it again. Figure 1 In some embodiments, the verification device 1 further includes a support rod 19, which is connected between the base 11 and the top plate 12 along a first direction, and the support rod 19 passes through the movable frame assembly 14.

[0084] The support rod 19 connects the base 11 and the top plate 12, which can maintain the stability of the verification device 1. At the same time, the support rod 19 passes through the movable frame assembly 14, so that the movable frame assembly 14 can only move along the support rod 19. The support rod 19 extends in the first direction, thereby ensuring that the movable frame assembly 14 can only move in the first direction.

[0085] Although the present invention has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
