[0024] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments.

Without conflict, the embodiments and features in the present application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Figure 1Shows an embodiment of an underground pipeline detection device of the present utility model. Refer to Figure 1 , in this embodiment, the underground pipeline detection device includes: a detection mechanism 1, a bearing mechanism 2, a holding mechanism 3, and a controller 4;

[0027] Furthermore, refer to Figure 2 , the detection mechanism 1 includes a connecting plate 11, detection discs 12, and position sensors 13; one set of opposite sides of the connecting plate 11 are each connected to a detection disc 12, and position sensors 13 are provided at the ends of the two detection discs 12 that are away from each other; the detection discs 12 are used to detect underground metals, and the position sensors 13 are used to monitor the positions of the two detection discs 12 in real time.

[0028] Preferably, the detection discs 12 are disc-shaped, and the axis of each detection disc 12 is perpendicular to the upper or lower end surface of the connecting plate 11; the detection discs 12 use alternating current passing through coils to generate a rapidly changing magnetic field, and this magnetic field can generate eddy currents inside metal objects. The eddy currents will in turn generate a magnetic field, which will affect the original magnetic field in reverse to achieve the detection of underground metals; by driving the detection mechanism 1 to rotate, the two detection discs 12 simultaneously detect underground metal pipelines. With the positioning function of the position sensors 13, when the two detection discs 12 simultaneously detect underground metals and with the positioning function of the position sensors 13, the path detection of underground pipelines can be achieved.

[0029] Furthermore, refer to Figure 3, the carrier mechanism 2 includes: a carrier plate 21, a first support plate 22, a second support plate 23, a first motor 24, a second motor 25, and a third motor 26; the upper or lower end surface of the carrier plate 21 is parallel to the upper end surface of the connecting plate 11, one end of the carrier plate 21 is perpendicularly connected to one end of the first support plate 22 to form a right-angle plate, and the second support plate 23 is disposed on the side of the first support plate 22 away from the carrier plate 21; the first motor 24 is disposed on the upper end surface of the carrier plate 21, and the rotating shaft of the first motor 24 vertically penetrates from the upper end surface of the carrier plate 21 to the lower end surface and is fixedly connected to the middle of the upper end surface of the connecting plate 11. The first motor 24 is used to drive the two detection disks 12 to rotate clockwise or counterclockwise around the axis of the rotating shaft of the first motor 24; the second motor 25 is disposed on the end surface of the first support plate 22 away from the second support plate 23, and the rotating shaft of the second motor 25 vertically penetrates from the end surface of the first support plate 22 close to the carrier plate 21 to the end surface away from the carrier plate 21 and is perpendicularly connected to one end surface of the second support plate 23. The second motor 25 is used to drive the first support plate 22 to rotate around the axis of the rotating shaft of the second motor 25; a connecting ear 27 is provided on the end surface of the second support plate 23 away from the first support plate 22, and one end of the detection rod 31 away from the controller 4 is rotatably connected to the connecting ear 27 through a rotating shaft 28. The third motor 26 is disposed on the second support plate 23, and the rotating shaft 28 is coaxially connected to the rotating shaft of the third motor 26 and is fixedly connected to the detection rod 31. The third motor 26 is used to drive the second support plate 23 to rotate around the axis of the rotating shaft of the third motor 26;

[0030] Further, referring to Figure 3 , the carrier device further includes an inclination sensor 29, and the inclination sensor 29 is disposed on the upper end surface of the carrier plate 21 and is used to monitor in real time the angle value between the upper or lower end surface of the carrier plate 21 and the horizontal plane.

[0031] Preferably, the axis of the rotating shaft of the second motor 25 is perpendicular to the axis of the rotating shaft of the third motor 26, and the axis of the rotating shaft of the third motor 26 is parallel to the horizontal plane in the initial state, so that the second motor 25 and the third motor 26 cooperate to adjust the angle between the upper or lower end surface of the carrier plate 21 and the horizontal plane.

[0032] For example, assume that in the initial state, the upper or lower end face of the bearing plate 21, the axis of the rotating shaft of the second motor 25, and the axis of the rotating shaft of the third motor 26 are such that the axis of the rotating shaft of the second motor 25 is parallel to the X-axis in the three-dimensional coordinate system, and the axis of the rotating shaft of the third motor 26 is parallel to the Y-axis in the three-dimensional coordinate system. The inclination sensor 29 real-time monitors the angle between the upper or lower end face of the bearing plate 21 and the horizontal plane. When the second motor 25 operates, since the bearing plate 21 and the first support plate 22 are an integral structure, the bearing plate 21 will rotate around the axis of the rotating shaft of the second motor 25, thereby realizing the adjustment of the angle between the upper or lower end face of the bearing plate 21 and the Y-axis; when the third motor 26 operates, since the axis of the rotating shaft of the second motor 25 is perpendicular to the axis of the rotating shaft of the third motor 26, and the axis of the rotating shaft of the third motor 26 is parallel to the horizontal plane, the bearing plate 21 will rotate around the axis of the rotating shaft of the third motor 26, thereby realizing the adjustment of the angle between the upper or lower end face of the bearing plate 21 and the X-axis. Through the coordinated operation of the second motor 25 and the third motor 26, the upper or lower end face of the bearing plate 21 can always be kept parallel to the horizontal plane, and thus the two detection discs 12 can always be kept parallel to the horizontal plane.

[0033] Further, referring to Figure 4 , the holding mechanism 3 further includes a fixing component 32 and a handle 33. The end of the detection rod 31 away from the second support plate 23 and on the side away from the bearing plate 21 is connected to the fixing component 32, and the handle 33 is located on the side of the fixing component 32 adjacent to the second support plate 23 and one end thereof is connected to the detection rod 31.

[0034] Further, referring to Figure 4 , the fixing component 32 includes a fixing plate 321 and a strap 322. The fixing plate 321 is an arc-shaped plate. The outer arc surface of the fixing plate 321 is connected to the detection rod 31 through a connecting block 323. Each end of the fixing plate 321 is connected to a strap 322, and a cushion layer is provided on the inner arc surface of the fixing plate 321; the arc-shaped design of the fixing plate 321 facilitates fitting to the human arm, and the strap 322 is used to tie the fixing plate 321 to the human arm, so as to provide support from the arm when the operator holds the handle 33 with one hand, which is conducive to keeping the detection mechanism 1 in a stable state during movement in the air.

[0035] Preferably, the strap 322 is a cloth strap provided with Velcro. The strap 322 at one end of the fixing plate 321 is provided with a fuzzy surface Velcro, and the strap 322 at the other end of the fixing plate 321 is provided with a hook surface Velcro, which improves the connection and disconnection process of the two straps 322.

[0036] Further, referring to Figure 4, the ground wire detection device further includes a controller 4. The detection mechanism is disposed on a side of the detection rod 31 away from the fixing assembly 32 and is connected to the detection rod 31. An operating member 41 for receiving an external touch operation and a display member 42 for displaying the touch operation and control instructions are disposed on an end surface of the controller 4 away from the bearing mechanism 2. A central control module with a number of control instructions is disposed inside the controller 4. The central control module is electrically connected to the detection disc 12, the position sensor 13, the first motor 24, the second motor 25, the third motor 26, the inclination sensor 29, the operating member 41, and the display member 42. The central control module is configured to identify the touch operation contacted by the operating member 41, as well as the data transmitted by the detection disc 12, the displacement sensor, and the inclination sensor 29, and match corresponding control instructions to respectively control the energization or de-energization of the first motor 24, the second motor 25, and the third motor 26, and the working frequency adjustment.

[0037] Preferably, a plurality of buttons may be provided on the operating member 41, and the display member 42 may be provided as a display screen; or the display member 42 may be directly provided as a liquid crystal touch screen, and then the operating member 41 and the display member 42 may be integrated into one body.

[0038] It should be noted that this embodiment focuses on the working principles of the detection disc 12, the position sensor 13, the first motor 24, the second motor 25, the third motor 26, the inclination sensor 29, the operating member 41, the display member 42, and the central control module. Its specific structure is not the focus of this embodiment. The structures, shapes, and models of the detection disc 12, the position sensor 13, the first motor 24, the second motor 25, the third motor 26, the inclination sensor 29, the operating member 41, the display member 42, and the central control module are all mature prior arts. Any existing device in the prior art that satisfies the principles of this embodiment can be installed.

[0039] In this application, the detection mechanism 1 is driven by the first motor 24 to rotate clockwise or counterclockwise in a plane along its axis. When the two detection discs 12 simultaneously detect underground metal pipelines, the radial direction of the underground pipelines at that location can be determined. Then, the position sensor 13 records the positions of each detection disc 12. Driving the ground wire detection device to move within a certain range can directly realize the detection of the underground pipeline path, eliminating the troublesome process of marking point by point.
