Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0045] In this embodiment, as Figure 1 and Figure 2As shown, a torque detection device for a submersible motor used in wells includes: a servo motor carrier 1, on which a servo motor 11 is mounted; a drive shaft 2, which is connected to the servo motor carrier 1 via bearings, and the top end of the drive shaft 2 is connected to the output end of the servo motor 11; a torque sensor 21, whose input end is connected to the drive shaft 2 via a first coupling 22, and whose output end is connected to the transmission part of the submersible motor via a second coupling 24; and a limiting member 23 is disposed on the outer periphery of the torque sensor 21, which is used to constrain the position of the torque sensor 21.

[0046] Thus, the top of the torque sensor 21 is connected to the drive shaft 2 via the first coupling 22, and the output end of the torque sensor 21 is connected to the transmission part of the submersible motor through the second coupling 24. Then, the servo motor 11 in the servo motor carrier 1 is started, and the servo motor 11 drives the drive shaft 2 to rotate in the servo motor carrier 1. The drive shaft 2 drives the transmission part of the submersible motor to rotate through the torque sensor 21. In the process of turning the machine, the torque sensor 21 detects the torque of the transmission part of the submersible motor, changing the traditional operation method of manually using a torque wrench for detection, and making it more efficient in batch detection.

[0047] Specifically, the servo motor support 1 is used to support the servo motor 11. The transmission shaft 2 rotates in the servo motor support 1 as the output shaft of the servo motor 11 rotates. The torque sensor 21 is installed between the transmission shaft 2 and the transmission part of the submersible motor for wells. The torque sensor 21 is used to detect the torque of the transmission part of the submersible motor for wells.

[0048] In some embodiments, such as Figure 4 As shown, the limiting component 23 includes: a limiting bracket 231, which has a U-shaped groove that is adapted to the outer periphery of the torque sensor 21; and two fixing screws 232, which are connected to the limiting bracket 231 through bearings, and the top ends of the two fixing screws 232 are connected to the internal threads of the servo motor bearing seat 1.

[0049] Specifically, the limiting bracket 231 is inserted into the outer periphery of the torque sensor 21 through a U-shaped groove. The design of the two fixing screws 232 prevents the limiting bracket 231 from rotating. The design of the limiting bracket 231 constrains the position of the torque sensor 21.

[0050] In some embodiments, such as Figure 3As shown, the servo motor carrier 1 is equipped with an adjustable mounting bracket 3, which is used to assist the servo motor carrier 1 in horizontal or vertical directions. The adjustable mounting bracket 3 includes: a fixed shaft 31, which is fixedly connected to the through hole of the servo motor carrier 1; two slotted plates 32, which are respectively disposed at both ends of the fixed shaft 31, and both slotted plates 32 are connected to the fixed shaft 31 through bearings, and the slotted plates 32 are connected to the servo motor carrier 1 through positioning pins 321; the side wall of the servo motor carrier 1 is machined with round holes, which are evenly distributed along the fixed shaft 31 and are adapted to the positioning pins 321; and an adjusting plate 33, which is located in the groove of the slotted plate 32, and is connected to the slotted plate 32 through a connector 34. A lifting plate 35 is fixedly connected to the end of the adjusting plate 33 away from the slotted plate 32.

[0051] Specifically, the fixed shaft 31 is installed in the through hole of the servo motor carrier 1, and the two slot plates 32 are symmetrically distributed based on the fixed shaft 31. The slot plates 32 are machined with grooves that are compatible with the adjusting plate 33. The adjusting plate 33 is machined with a strip-shaped sliding groove. The lifting plate 35 is used to connect with the external installation object.

[0052] In some embodiments, such as Figure 3 As shown, the connector 34 includes a threaded pin 341 and a nut 342; one end of the threaded pin 341 is fixedly connected to the groove plate 32, and the other end of the threaded pin 341 passes through the groove of the adjusting plate 33 and is connected to the nut 342.

[0053] Each slot plate 32 is provided with a threaded pin 341, which, together with the nut 342, fixes the position of the adjusting plate 33 in the slot plate 32.

[0054] In some embodiments, such as Figure 4 As shown, the lifting plate 35 is equipped with lifting rings 351, which are symmetrically distributed based on the lifting plate 35.

[0055] Specifically, there are two lifting rings 351. The use of lifting rings 351 facilitates the lifting of the entire mechanism by external wire ropes.

[0056] In some embodiments, such as Figure 5 As shown, an auxiliary support rod 4 is fixedly connected to the bottom end of the servo motor carrier 1; the auxiliary support rod 4 includes: a snap-fit ​​plate 41, which is located in the snap-fit ​​groove of the servo motor carrier 1 and is connected to the servo motor carrier 1 by bolts 411; and a positioning sleeve 42, whose top end is fixedly connected to the snap-fit ​​plate 41 and has a cavity.

[0057] The snap-fit ​​plate 41 is adapted to the slot of the servo motor carrier 1, and the bolt 411 connects the snap-fit ​​plate 41 to the servo motor carrier 1. The positioning sleeve 42 can be directly inserted into the positioning hole of the well submersible motor.

[0058] In some embodiments, such as Figure 5 As shown, an extension member 43 is installed in the cavity of the positioning sleeve 42; the extension member 43 includes an extension rod 431 and a limiting pin 432; the extension rod 431 is adapted to the cavity of the positioning sleeve 42, and the extension rod 431 is connected to the positioning sleeve 42 through the limiting pin 432.

[0059] Specifically, when the integrated mechanism is used vertically, if the distance between the positioning sleeve 42 and the well submersible motor is far, the position of the extension rod 431 is adjusted. The limit pin 432 is threaded and is used to fix the position of the extension rod 431 in the positioning sleeve 42.

[0060] In some embodiments, such as Figure 5 As shown, the extension rod 431 has threaded holes evenly distributed, and the threaded holes are adapted to the limit pin 432.

[0061] The position of the extension rod 431 in the positioning sleeve 42 is changed, and the limiting pin 432 is inserted into the threaded hole of the extension rod 431 to fix the position of the extension rod 431 in the positioning sleeve 42.

[0062] In some embodiments, such as Figure 5 As shown, the bottom end of the extension rod 431 is threadedly connected to a positioning joint 433, which is adapted to the groove of the well submersible motor.

[0063] The outer diameter of the positioning connector 433 is the same as the outer diameter of the positioning sleeve 42, and the positioning connector 433 can be inserted into the groove of the well submersible motor.

[0064] In some embodiments, such as Figure 1 As shown, the card plate 41 is symmetrically distributed based on the servo motor carrier 1.

[0065] The design of the two snap-fit ​​plates 41, in conjunction with the use of the positioning sleeve 42, increases the stability of the torque sensor 21.

[0066] The working principle of this application is illustrated below with a preferred embodiment:

[0067] The servo motor carrier 1 is connected to an external installation object via the lifting plate 35. The servo motor carrier 1 rotates between the two slot plates 32, causing the fixed shaft 31 to rotate within the slot plate 32. The position of the servo motor carrier 1 is fixed using the positioning pin 321 (adjusting the servo motor carrier 1 to a vertical or horizontal position according to actual usage requirements). The slot plate 32 is moved along the outer wall of the adjusting plate 33, causing the threaded pin 341 to move within the groove of the adjusting plate 33. The position of the adjusting plate 33 within the slot plate 32 is fixed using the nut 342. The clamping plate 41 is connected to the servo motor carrier 1 using bolts 411. The extension rod 431 is moved within the positioning sleeve 42. 431 drives the positioning connector 433 to be inserted into the positioning slot of the submersible motor, and the position of the extension rod 431 in the positioning sleeve 42 is fixed by the limit pin 432. The input end of the torque sensor 21 is connected to the transmission shaft 2 through the first coupling 22. Then, the output end of the torque sensor 21 is connected to the transmission part of the submersible motor through the second coupling 24. Then, the servo motor 11 in the servo motor carrier 1 is started to drive the transmission shaft 2 to rotate in the servo motor carrier 1. The transmission shaft 2 drives the transmission part of the submersible motor to rotate through the torque sensor 21. Then, during the turning process, the torque sensor 21 detects the torque of the transmission part of the submersible motor.
