The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] like Figure 1-Figure 5 As shown, the utility model provides a technical solution for a magnetic memory detection probe positioning device, comprising a vehicle body 1, a detection mechanism 2 being provided on the vehicle body 1, and a ruler rope 3 being provided on one side of the vehicle body 1, a starting plate 4 being provided at the movable end of the ruler rope 3, a winding rod 5 being rotatably connected to the starting plate 4, the movable end of the ruler rope 3 being fixedly wound around the outer side of the winding rod 5, two mounting plates 11 being installed on the upper part of the starting plate 4, two rollers 6 being rotatably connected between the two mounting plates 11, the outer sides of the rollers 6 being provided with a rubber material, the two rollers 6 being respectively in extrusion contact with the two sides of the ruler rope 3, a counter for recording the number of revolutions of the rollers 6 being provided on the starting plate 4, and two telescopic blocking rods 7 being installed on the side of the starting plate 4 located on the vehicle body 1;

[0025] Place the starting plate 4 against one end of the pipe, with the telescopic stopper 7 resting against the pipe opening. Simultaneously, the vehicle body 1 is moved within the pipe, releasing the ruler rope 3 as the vehicle body 1 moves. Due to the tight contact between the roller 6 and the ruler rope 3, the ruler rope 3 can drive the roller 6 to rotate. The released length of the ruler rope 3 and the travel distance of the vehicle body 1 can be determined based on the number of revolutions and the circumference of the roller 6.

[0026] The vehicle body 1 is a remote-controlled vehicle in the prior art, and its usage and form are not described in detail;

[0027] When the vehicle body 1 moves in the pipeline, it will be detected by the detection mechanism 2.

[0028] like Figure 2 and Figure 4 As shown, the counter includes a small battery 8 , a display screen 9 and a controller 10 mounted on the starting board 4 . The small battery 8 is electrically connected to the controller 10 , and the controller 10 is electrically connected to the display screen 9 .

A spring is provided between the movable end of the seesaw 12 and the inner wall of the groove. A touch block 13 is fixedly connected to the eccentric axis of the end of the roller 6. The touch block 13 is located in the cavity of the groove and is located on the side of the axis of the seesaw 12. The touch block 13 contacts the end of the seesaw 12. The switch key 23 provided on one side of the controller 10 contacts the other end of the seesaw 12. A shaft is installed at the center of the seesaw 12, and the shaft is rotatably connected to the inner wall of the groove.

[0030] When the roller 6 rotates, the roller 6 drives the touch block 13 to rotate around the axis of the roller 6. Every time the roller 6 rotates one circle, the touch block 13 will contact one end of the seesaw 12 and push the seesaw 12 to rotate, so that the other end of the seesaw 12 can be tilted up and contact the switch key 23. The switch key 23 is pressed using the other end of the seesaw 12, thereby starting the controller 10 to count once. Therefore, the number of rotations of the roller 6 is known based on the number of counts, and the release length of the ruler rope 3 is known based on the number of rotations of the roller 6. The count value of the controller 10 will be displayed on the display screen 9, so it is convenient for the staff to understand the situation in time.

[0032] By rotating the bevel gear ring 15, the bevel gear ring 15 drives each bevel gear 16 to rotate, and the bevel gear 16 uses the threaded rod 17 to drive the magnetic probe 18 away from or close to the turntable 14. In this way, the position of the magnetic probe 18 can be adjusted according to the size of the inner diameter of the pipeline, so as to facilitate the magnetic probe 18 to approach the inner wall of the pipeline, thereby improving the accuracy of the detection of the magnetic probe 18.

[0033] like Figure 3 As shown, the limiting assembly includes a limiting rod 19 and a limiting plate fixedly connected to each other. The limiting plate is fixedly connected to one side of the threaded rod 17. A limiting groove is opened on the outer side of the rotating disk 14 at a position corresponding to the limiting rod 19. The limiting rod 19 is slidably connected to the limiting groove. The limiting rod 19 is located on one side of the threaded rod 17.

[0034] The limiting rod 19 can be used to limit the rotation of the threaded rod 17, so that the magnetic sensitive probe 18 can be driven to move by the threaded rod 17.

[0035] like Figure 3As shown, the bottom of the vehicle body 1 is rotatably connected to two rollers, and wheels 20 are fixedly connected to both ends of the rollers. Two servo motors 21 are installed on the vehicle body 1. The movable ends of the two servo motors 21 are fixedly connected to the outer sides of the rollers and one side of the turntable 14 respectively. The servo motors 21, small batteries 8, display screens 9 and controllers 10 used in this application are all purchased parts, which are selected according to power and size requirements. The system of the controller 10 adopts the module provided by the corresponding merchant. This application will not go into too much detail. The servo motors 21 are electrically connected to the power supply, and a battery is provided in the vehicle body 1. The servo motors 21 are electrically connected to the battery.

[0036] Two servo motors 21 are used to respectively drive the turntable 14 and the roller to rotate, thereby facilitating the movement of the vehicle body 1 and the rotation of the turntable 14 .

[0037] like Figure 3 As shown, a circular groove is formed at the movable end of the threaded rod 17, in which a ball 22 is placed, and the ball 22 contacts the inner wall of the pipe;

[0038] The ball bearings 22 are used to reduce the friction between the movable end of the threaded rod 17 and the inner wall of the pipe, thereby facilitating the stable movement of the vehicle body 1.

[0039] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention.
