[0002] Wireless LWD inclinometers have been relatively widely used in the drilling industry of oil drilling rigs. The centralizer of a wireless LWD inclinometer, as a general interface connecting various parts of the instrument, its reliability and durability have become issues that oilfield users are more concerned about, because it directly affects the service life of the wireless LWD inclinometer and the success rate of running it into the well. The centralizer device is used at the end of the LWD inclinometer to prevent bending and vibration to ensure the accuracy of measurement data.

[0003] Most of the existing centralizer devices at the end of wireless LWD inclinometers are of an integrated structure design, making it inconvenient to replace when there are problems with the centralizer device. Moreover, the existing centralizer devices at the end of wireless LWD inclinometers lack an adjustment device and cannot well adapt to different models of inclinometers, resulting in relatively low flexibility.

[0004] Therefore, aiming at the above-mentioned situation where most of the existing centralizer devices at the end of wireless LWD inclinometers are of an integrated structure design, inconvenient for disassembly and assembly, and lacking an adjustment device, making the centralizer device unable to well adapt to different models of inclinometers and having relatively low flexibility. Thus, a centralizer device at the end of a wireless LWD inclinometer that is convenient for disassembly and assembly can be designed. By inserting a slider into a limit hole, the centralizer device can be disassembled and assembled, and by rotating a rocker, a moving plate can be moved to facilitate adapting to different models of inclinometers and improve the flexibility of the device. Summary of the Utility Model

A threaded rod 3 is arranged inside the straightening pipe 2. Both the upper and lower ends of the threaded rod 3 are rotatably connected with mounting frames 31. The surface of the mounting frame 31 is fixedly connected with the straightening pipe 2. A threaded block 32 is threadedly connected to the surface of the threaded rod 3. A chute 21 is formed on the surface of the straightening pipe 2, and a connecting rod 6 is slidably connected in the chute 21. A fixed seat 9 is fixedly installed at the lower end of the surface of the straightening pipe 2. A fixing plate 10 is rotatably connected to the fixed seat 9. A moving plate 8 is arranged at the upper end of the fixing plate 10. One end of the moving plate 8 away from the fixing plate 10 is rotatably connected with a moving seat 7. A disassembly seat 11 is fixedly installed at the lower end of the straightening pipe 2. The disassembly seat 11 is detachably connected to the upper end of the tester 1. A slider 111 is arranged on the surface of the disassembly seat 11. By rotating the threaded rod 3, the threaded block 32 drives the connecting rod 6 to move along the chute 21 synchronously, and drives the moving seat 7 to move synchronously, so that the moving plate 8 pushes the fixing plate 10, thereby completing the adjustment of the straightening pipe 2, facilitating work in different environments. At the same time, the disassembly seat 11 and the tester 1 are detachably connected through the slider 111, facilitating the replacement of the straightening pipe 2 and improving the convenience.

[0024] Please refer to Figure 1 , Figure 2 and Figure 3 , in this embodiment, the upper end of the threaded rod 3 extends to the outside of the straightening pipe 2 and is fixedly connected with a turning handle 4. A rocker 5 is arranged on the surface of the turning handle 4. By setting the turning handle 4, it is convenient for the staff to rotate the threaded rod 3, improving the convenience. There are four chutes 21. One end of the connecting rod 6 is fixedly connected with the threaded block 32, and the other end of the connecting rod 6 is fixedly connected with the moving seat 7, facilitating the simultaneous straightening of the four sides of the straightening pipe 2 and improving the stability of the straightening pipe 2.

By driving the fixing plate 10 to rotate synchronously through the moving plate 8, it is convenient for the staff to adjust the device and improves the convenience.

[0025] Please refer to Figure 2 and Figure 4In this embodiment, two sliders 111 are symmetrically arranged, and a fixing rod 112 is fixedly installed inside the slider 111. The fixing rod 112 extends into the disassembly seat 11 at one end away from the slider 111, and a limiting plate 113 is fixedly installed. The fixing rod 112 is slidably connected with the disassembly seat 11. By pushing the tester 1, the fixing rod 112 moves inward, which is convenient for the staff to disassemble and assemble the disassembly seat 11 and the tester 1.
