[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Please see Figures 1-5 This utility model discloses an underground pipeline detection instrument, including an operating main rod 1 and a handle 2 located at one end of the operating main rod 1, and also includes an angle adjustment component 3, a counterweight balance component 4, a tilt angle adjustment component 5, and a buffer protection component 6, wherein:

[0024] A signal processor 11 is welded onto the main operating rod 1. The processor 11 is equipped with a display screen 111 and a motor control button 112. Specifically, the motor control button 112 can control the opening and closing of the servo motor 31 and the electric telescopic rod 52.

[0025] Please refer to the appendix. Figure 3 The angle adjustment component 3 includes a micro servo motor 31, which is fixed to one side of the operating main rod 1 by screws. One end of the servo motor 31 is connected to the linkage gear 32. One end of the operating main rod 1 is fitted with a rotating column 33 and rotates in cooperation. The outer side of the rotating column 33 is provided with annular serrations 331, which mesh with the linkage gear 32. Specifically, the micro servo motor 31 can drive the linkage gear 32 to rotate, and then use the meshing motion of the annular serrations 331 to make the rotating column 33 rotate in the operating main rod 1. The rotating column 33 uses the rectangular column 62 to drive the bottom column 53 to rotate, and then drives the detection frame 51 to rotate to achieve adjustment.

[0026] Please refer to the appendix. Figure 4The counterweight balancing component 4 includes a slide groove 41, which is fitted with a counterweight 42 and slides in a sliding fit. An adjustment plate 43 is welded to the top surface of the counterweight 42. Both ends of the adjustment plate 43 are fitted with elastic columns 44 and slide in a sliding fit. One end of the elastic column 44 is connected to a ball 45, and the other end is connected to a spring 46. The ball 45 is fitted into a circular groove 47.

[0027] A handle 2 is welded to one end of the slide groove 41. A rubber sleeve 21 is nested in the handle 2. Circular grooves 47 are equidistantly arranged on the inner side of the slide groove 41. A latex pad 411 is attached to the top of the slide groove 41. Specifically, the rubber sleeve 21 can increase the friction of the handle 2, making the grip more secure. The latex pad 411 can support the elbow when holding the handle 2, reducing wrist pressure and making it more comfortable.

[0028] In this embodiment, the adjustment plate 43 can be moved to make the counterweight 42 slide in the slide groove 41. When the counterweight 42 slides, the round beads 45 on both sides of the adjustment plate 43 can slide back and forth in each round groove 47. After the adjustment is completed, the spring 46 rebounds and squeezes the elastic column 44. The elastic column 44 fixes the position of the counterweight by using the engagement of the round beads 45 and the round groove 47, so as to achieve the effect of adjusting the center of gravity of the device to save effort. Example 2

[0029] Based on the above embodiment 1, please refer to the appendix. Figure 3 as well as Figure 5 The tilt angle adjustment component 5 includes a detection frame 51, on which electromagnetic transmitting tubes 511 and electromagnetic receiving tubes 512 are welded perpendicularly to each other. The electromagnetic transmitting tubes 511 and electromagnetic receiving tubes 512 are electrically connected to the signal processor 11.

[0030] The inner side of one end of the detection frame 51 is connected to the electric telescopic rod 52, and the other end of the electric telescopic rod 52 is connected to the base column 53 and rotates with it. The bottom end of the base column 53 is connected to the detection frame 51 and rotates with it.

[0031] A rubber pad 513 is attached to the bottom of the detection frame 51. Specifically, the rubber pad 513 can protect the electromagnetic transmitting tube 511 and the electromagnetic receiving tube 512 of the detection frame 51, and prevent them from being damaged by repeated impacts to the bottom surface during detection.

[0032] The buffer protection component 6 includes a buffer chassis 61, one end of a rotating column 33 is welded to the buffer chassis 61, and a rectangular column 62 is provided on one side of the buffer chassis 61. One end of the rectangular column 62 is fitted into one end of the bottom column 53 and is slidably engaged.

[0033] A damper 63 is provided around the rectangular column 62. One end of the damper 63 is fixed to the buffer base 61 by screws, and the other end is connected to the buffer spring 64. The buffer spring 64 is welded to one end of the base column 53.

[0034] In this embodiment, the electric telescopic rod 52 can be activated as needed to detect the inclination of the bottom surface. The electric telescopic rod 52 drives the detection frame 51 to rotate around one end of the base column 53 through its telescopic action, thereby changing the inclination angle so that it can be parallel to the ground and improve the detection accuracy. After the detection frame 51 hits the bottom surface, the base column 53 receives the impact force and compresses the buffer spring 64. The buffer spring 64 drives the damper 63 to convert the impact force into heat energy for dissipation, thereby reducing the impact force and improving the service life of the equipment.

[0035] The working principle and usage process of this utility model are as follows: When using this device, first hold the handle 2 to lift the detection frame 51, and start the electric telescopic rod 52 according to the required inclination of the bottom surface. The electric telescopic rod 52 drives the detection frame 51 to rotate around one end of the bottom column 53 through the telescopic action, thereby changing the inclination angle so that it can be parallel and close to the ground, improving the detection accuracy.

[0036] When conducting detection in wide areas, the micro servo motor 31 can be activated to drive the linkage gear 32 to rotate, and then the meshing motion of the annular sawtooth 331 will cause the rotating column 33 to rotate in the operating main rod 1. The rotating column 33 will drive the base column 53 to rotate through the rectangular column 62, which in turn will drive the detection frame 51 to rotate, adjusting it to be perpendicular to the projection of the operating main rod 1 on the vertical plane, thereby achieving the widest detection path and improving detection efficiency. When encountering narrow alleys, the micro servo motor 31 can be activated to reduce the included angle of the detection frame 51, thereby facilitating detection.

[0037] During detection, the position of the counterweight can be adjusted according to one's own habits and the inclination angle of the detection surface to balance the center of gravity of the detection end and achieve the effect of saving effort. The adjustment can be achieved by moving the adjustment plate 43 to drive the counterweight 42 to slide in the slide groove 41. When the counterweight 42 slides, the round beads 45 on both sides of the adjustment plate 43 can slide back and forth in each round groove 47. After the adjustment is completed, the spring 46 rebounds and squeezes the elastic column 44. The elastic column 44 fixes the position of the counterweight by the engagement of the round beads 45 and the round groove 47.

[0038] During detection, the rubber pad 513 can protect the detection tube and receiving tube of the detection frame 51, preventing them from being repeatedly hit by the bottom surface and causing damage. At the same time, after the detection frame 51 hits the bottom surface, the bottom column 53 receives the impact force and compresses the buffer spring 64. The buffer spring 64 drives the damper 63 to consume the buffer energy, thereby reducing the impact force and protecting the equipment.

[0039] Finally, the signal processor 11 is activated to generate an alternating current, which causes the coil inside the electromagnetic transmitter tube 511 to generate an electromagnetic field and emit it to the ground. The electromagnetic wave causes the underground pipeline to generate current, which in turn generates an electromagnetic field around it. The electromagnetic receiver tube 512 captures the distribution and changes of the magnetic field and transmits the signal back to the signal processor 11. By analyzing the magnetic field strength, direction and phase difference, the location, direction and depth of the pipeline are determined and displayed on the display screen 111 for observation.
