Detailed implementation manner

[0025] The technical solution of the present invention will be described in detail below with reference to the accompanying drawings and embodiments.

[0026] As Figure 1 shown, a magnetic metal pipeline detection device includes a box body 1. An auxiliary induction component is provided on the top of the box body 1, an electric hammer 2 is provided on the side, and electronic devices such as a storage battery, a communication device, and a processor are provided inside. Among them, the electric hammer 2 is used to continuously strike the metal pipeline during driving. If there is a crack in the pipeline, abnormal sound waves will be generated; Wheels 3 are symmetrically provided on both sides of the box body 1, and the two are connected by a fixed shaft 4. As Figure 2 shown, the wheels 3 are made of rubber, and a number of induction chips 5 are embedded in the wheel surface. Further, the induction chips 5 are electromagnets.

[0027] A driving device 6, a rotating disk 7, and a fixed disk 8 are sequentially provided on the side of the wheel 3 corresponding to the fixed shaft 4. Among them, a stepping motor is provided in the driving device 6, and it is connected to the rotating disk 7 through a number of support rods 9. The driving device 6 is used to drive the rotating disk 7 to rotate; Both the rotating disk 7 and the fixed disk 8 are sleeved outside the fixed shaft 4. The side of the rotating disk 7 corresponding to the fixed disk 8 is provided with a first jack 7a and a second jack 7b. Among them, the number of the first jacks 7a is several, the number of the second jacks 7b is one, and the distance from the center of the rotating disk 7 to the first jack 7a is greater than its distance to the second jack 7b. Further, an anode contact structure 7c is provided in the first jack 7a, which is connected to the anode of the induction chip 5 through a wire, and a cathode contact structure 7d is provided in the second jack 7b, which is connected to the cathode of the induction chip 5 through a wire; Specifically, both the anode contact structure 7c and the cathode contact structure 7d are composed of a conductive sheet and a spring. The spring can continuously press the conductive sheet to ensure its contact with the conductive block of the fixed disk 8.

[0028] The fixed disk 8 is connected to the fixed shaft 4 by bolts. At the position corresponding to the anode contact structure 7c, a semi-circular anode conductive block 8a is provided, and at the position corresponding to the cathode contact structure 7d, a circular cathode conductive block 8b is provided. The anode conductive block 8a and the cathode conductive block 8b are respectively connected to the power supply lines in the box body 1. Since the rotating disk 7 and the fixed disk 8 are in close contact, when the rotating disk 7 rotates with the wheel 3, some of the anode contact structures 7c sequentially contact the anode conductive block 8a, while the cathode contact structure 7d always contacts the cathode conductive block 8b. At this time, the induction sheet 5 in contact with the metal pipe is energized, and the induction sheet 5 not in contact with the metal pipe is de-energized, so as to ensure that the wheel 3 can be adsorbed on the metal pipe and keep running on the metal pipe.

[0029] As Figure 3 shown, the auxiliary induction component includes an electric push rod 10. The electric push rod 10 is hingedly connected to the box body 1. A Y-shaped connecting plate 11 is provided at the top and a gear 12 is provided at the bottom. Among them, an auxiliary wheel 13 is provided at the top of the connecting plate 11, and the auxiliary wheel 13 has the same structure as the wheel 3. An electric motor 12a is provided in the box body 1, and the gear 12 is driven by the electric motor 12a. When the electric motor 12a rotates, it will drive the electric push rod 10 to swing. The electric motor 12a is connected to a sensor. When the electric push rod 10 swings and encounters a large resistance, the electric motor 12a will stop moving or even rotate in the reverse direction. In addition, a support 10a is also installed on the box body 1, and the support 10a is used to store the electric push rod 10.

[0030] In addition, a sound wave generator 14 and a sound wave receiver 15 are provided on the top of the box body 1, and a driving track recorder 16 is provided on the side. Among them, the sound wave receiver 15 is used to receive the sound waves reflected from the inner wall of the pipe and send them to the processor for analysis through a communication device. The processor will determine the direction of the pipe ahead according to the reflection of the sound waves and guide the device to move forward, and analyze the sound waves after resonance with the metal pipe to determine whether there is damage to the metal pipe. The driving track recorder 16 is used to record the driving track, so as to generate a three-dimensional route map. The processor marks the detected damage points on the route map, and the staff can easily find the specific surface position of the underground pipe damage point by analyzing and processing the route map.

[0031] When the present invention is in use, it is first placed at the entrance of the metal pipeline, and the electric push rod 10 is swung to the rear side of the box body 1. Then, the acoustic wave transmitter 14, the acoustic wave receiver 15, the driving track recorder 16 and the electric hammer 2 are started, and it begins to automatically move forward along the pipeline. During this period, the acoustic wave transmitter 14 will emit a frequency that can resonate with the metal pipeline outward, the electric hammer 2 will strike the metal pipeline, and the acoustic wave receiver 15 will send the above two kinds of acoustic waves to the processor for analysis. That is, the processor first determines the forward path of the robot by using the reflected acoustic waves, and then determines the damage points of the metal pipeline by analyzing the received acoustic waves, and marks the damage points on the three-dimensional route recorded by the driving track recorder 16.

[0032] During the driving process, if the pipeline is relatively flat, the controller of the device will automatically stop supplying power to the anode conductive block 8a and the cathode conductive block 8b, and it will move forward only by the rotation of the wheels 3; if it needs to walk in a relatively steep pipeline, the controller supplies power to the anode conductive block 8a and the cathode conductive block 8b, so that the induction sheet 5 in contact with the pipeline generates magnetic force, increasing the adsorption force between the wheels 3 and the metal pipeline and avoiding slipping during forward movement.

[0033] As Figure 4 shown, if it needs to pass through a vertically upward pipeline, the controller will supply power to the induction sheet 5, and at the same time extend the electric push rod 10, and the electric motor 12a controls the electric push rod 10 to swing, so that the auxiliary wheel 13 contacts the upper surface of the pipeline. At this time, the four wheels 3 and an auxiliary wheel 13 are adsorbed on the pipeline by magnetic force and rotate continuously, so that the device climbs the vertical pipeline. During the climbing process, the electric motor 12a and the sensors on it will ensure that the auxiliary wheel 13 always contacts the upper surface of the pipeline; as Figure 5 shown, if it needs to pass through a vertically downward pipeline, its working principle is the same as that of passing through a vertically upward pipeline.

[0034] When it is necessary to return to the starting point, only the direction of the current in the driving device 6 inside the wheel 3 needs to be changed to make the wheel 3 rotate in the reverse direction. At this time, it can retreat to the starting point. After changing the driving direction, start the electric motor 12a to control the electric push rod 10 to rotate 180 degrees, so that the auxiliary induction component is in the rear side direction when the box body 1 is driving.
