It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0026] In order to solve the technical problem in the prior art that the pipeline repair equipment has a limited length and can only repair the parts closer to the pipeline end, and the parts deeper in the pipeline cannot be repaired, resulting in limited use, the present utility model provides a coil-coupled magnetization assembly, which can quickly repair damaged pipelines without excavating the ground, with convenient construction and high repair efficiency.

[0027] Please refer to Figure 1 , Figure 1FIG. 0 is a schematic structural diagram of a coil-coupled magnetization component 100 in an embodiment of the present utility model. The coil-coupled magnetization component 100 is used in cooperation with a magnetic capsule to drive the magnetic capsule to move to a damaged part of a pipeline, and then perform a fixed-point explosion on the magnetic capsule, driving the magnetic adhesive stored in the magnetic capsule to adhere to the damaged part of the pipeline, thereby completing the repair of the damaged part of the pipeline. The coil-coupled magnetization component 100 includes a box body 1, an electromagnetic coil 2 and an induction coil 3 arranged in the box body 1. The electromagnetic coil 2 can magnetically attract the magnetic capsule located in the underground pipeline when energized, so that the coil-coupled magnetization component 100 can be moved to drive the magnetic capsule to move in the pipeline to the damaged part of the pipeline through magnetic attraction.

[0028] The induction coil 3 can drive the heating coil of the magnetic capsule to generate heat when energized, so that the capsule body of the magnetic capsule melts and releases a colloid to adhere to the damaged part of the pipeline, thereby completing the repair of the damaged part of the pipeline. It can be seen that compared with the prior art, the coil-coupled magnetization component 100 of the present application can not only drive the magnetic capsule to quickly move to the damaged part of the pipeline, but also heat and explode the magnetic capsule directionally, so that the magnetic adhesive of the magnetic capsule is released to repair the damaged part of the pipeline, and can repair any position of the pipeline, and the operation is simple and convenient.

[0029] In one embodiment, please refer to Figure 2 , the box body 1 includes a box body 11, a box cover 12 and a positioning member 13. An accommodating cavity 111 is arranged in the box body 11. The positioning member 13, the electromagnetic coil 2 and the induction coil 3 are all located in the accommodating cavity 111, and both the electromagnetic coil 2 and the induction coil 3 are connected to the positioning member 13 and fixed. The box cover 12 is detachably covered on the box body 11. In this embodiment, components such as the electromagnetic coil 2 and the induction coil 3 are all arranged in the box body 1, so as to facilitate the integration of multiple functions, and by moving the box body 1, the magnetic capsule located inside the pipeline can be driven to move to the damaged part of the pipeline.

[0030] In one embodiment, please refer to Figure 1 , a handle 14 is arranged on the side of the box cover 12 facing away from the box body 11. Maintenance personnel can manually pull the handle 14 to drive the coil-coupled magnetization component 100 to move, thereby driving the magnetic capsule to move to the damaged part of the pipeline. It should be emphasized that there are various ways to determine the damaged part of the pipeline. For example, the existing ultrasonic leak detection is used to detect the water leakage point, or a robot with a built-in camera is placed inside the pipeline. The robot takes pictures of the pipeline in sequence while moving in the pipeline, and uploads the taken images to the terminal device for maintenance personnel to refer to. The maintenance personnel can determine the damaged part of the pipeline by viewing the images of the terminal device.

[0031] In one embodiment, please refer to Figure 2, an opening 112 communicating with the accommodating cavity 111 is formed at one end of the box body 11 away from the box cover 12, and the induction coil 3 is disposed close to the opening 112. In this embodiment, by providing the opening 112, the electromagnetic induction effect between the induction coil 3 and the heating coil in the magnetic capsule is stronger, which can accelerate the heating efficiency of the heating coil and accelerate the melting of the magnetic capsule to release the magnetic glue.

[0032] In one embodiment, please refer to Figure 2 , the box body 11 is in the shape of a cuboid, the induction coil 3 is disposed parallel to the bottom surface of the box body 11, and the projection of the electromagnetic coil 2 on the bottom surface of the box body 11 is located inside the projection of the induction coil 3 on the bottom surface of the box body 11, so that the occupied space of the electromagnetic coil 2 and the induction coil 3 is smaller, the size of the box body 11 can be reduced, and it is convenient to carry.

[0033] In one embodiment, please refer to Figure 2 , the inner wall size of the box cover 12 is not larger than the outer wall size of the box body 11, and the box cover 12 is snap-fitted with the box body 11 with an interference fit, so that the box cover 12 and the box body 11 can be detachably connected, and the disassembly and assembly are fast and convenient.

[0034] In one embodiment, please refer to Figure 2 , the positioning member 13 is fixed to the accommodating cavity 111 by screws, and the electromagnetic coil 2 is fixed inside the positioning member 13. The coil coupling and magnetizing assembly 100 further includes a plurality of cooling fans 4, and the plurality of cooling fans 4 are disposed around the periphery of the positioning member 13, and each cooling fan 4 is in a different heat dissipation direction, so as to facilitate heat dissipation of the electromagnetic coil 2 and the induction coil 3. Figure 3 The illustrated embodiment is provided with three cooling fans 4, and the three cooling fans 4 are all connected to the box body 11 by screws. Three cooling openings 113 are provided on three side surfaces of the box body 11, and the three cooling openings 113 are correspondingly arranged with the three cooling fans 4, so that the three cooling fans 4 can respectively take out the heat in the accommodating cavity 111 from the three cooling openings 113, which is beneficial to improving the heat dissipation efficiency.

[0035] In one embodiment, please refer to Figure 1 and Figure 2, the coil coupling magnetization assembly 100 further includes a power supply 5 and a control board 6 disposed inside the box body. The power supply 5 is electrically connected to the control board 6 and is used to supply power to the control board 6. The control board 6 is connected to the electromagnetic coil 2 and the induction coil 3 and is used to supply power to the electromagnetic coil 2 and the induction coil 3, so that the electromagnetic coil 2 can magnetically attract the magnetic capsule when energized, and the induction coil 3 can establish electromagnetic induction with the heating coil of the magnetic capsule when energized to melt the capsule body of the magnetic capsule to release the magnetic glue. The power supply 5 in this embodiment can also be used as a battery and has a certain power storage function. A plurality of connectors 51 are also provided on the power supply 5. One of the connectors 51 can be used to connect an external charger to charge the power supply 5. Another connector 51 can be used to electrically connect to the control board 6 to electrically connect the power supply 5 and the control board 6. In addition, the power supply 5 is also provided with a display screen 52, and the display screen 52 can be used to display the working states of the electromagnetic coil 2 and the induction coil 3, such as whether the electromagnetic coil 2 is normally energized, the magnitude of the current and voltage, and whether the induction coil 3 establishes a normal connection with the heating coil of the magnetic capsule, etc., for the reference of maintenance personnel.

The power supply 5 also has a USB interface 54, and the USB interface 54 can be used to connect a charging cable or a data cable for charging a mobile phone or transmitting data.

[0036] In a second aspect, please refer to Figure 3 and Figure 4 , the present invention also provides a pipeline repair device, including a magnetic capsule 7 and the above-mentioned coil coupling magnetization assembly 100. The magnetic capsule 7 includes an upper half shell 71, a lower half shell 72, a heating coil 73, a coiled pipe 74 and a magnetic glue (not shown in the figure). Among them, magnetic glue is encapsulated inside both the upper half shell 71 and the lower half shell 72. The heating coil 73 is arranged around the peripheral side edge of the lower half shell 72 and is embedded inside the lower half shell 72 to facilitate the bonding of the upper half shell 71 and the lower half shell 72. The coiled pipe 74 is located inside the heating coil 73 and is connected to the heating coil 73. When the induction coil 3 of the coil coupling magnetization assembly 100 is energized, it can generate current for the heating coil 73 through electromagnetic induction, so that the heating coil 73 drives the coiled pipe 74 to heat up. Both the upper half shell 71 and the lower half shell 72 are made of plastic material. When the coiled pipe 74 heats up, it can melt both the upper half shell 71 and the lower half shell 72 to release the magnetic glue inside the upper half shell 71 and the lower half shell 72. When the magnetic glue is released, it can adhere to the pipeline breakage under the adsorption force of the electromagnetic coil 2 of the coil coupling magnetization assembly 100 for plugging, thereby completing the repair of the pipeline. After the magnetic glue has adsorbed for a period of time, such as ten minutes, the coil coupling magnetization assembly 100 can be removed.

[0037] In one of the embodiments, please refer to Figure 3, the shape of the magnetic capsule 7 is approximately spherical, so that when the magnetic capsule 7 encounters an obstacle inside the pipeline, it can roll over the obstacle to quickly reach the pipeline break. In other embodiments, the shape of the magnetic capsule 7 can also be set to spherical, so that the magnetic capsule 7 has stronger rolling ability.

[0038] To better understand the present invention, the following will Figures 1 to 4 describe the technical solution of the present invention in detail:

[0039] The coil coupling magnetization assembly 100 provided by the present invention is used in cooperation with the magnetic capsule 7. When repairing a pipeline, the magnetic capsule 7 can be first placed into the pipeline from the pipeline inlet, and the electromagnetic coil 2 of the coil coupling magnetization assembly 100 is controlled to be energized, so that the electromagnetic coil 2 magnetically attracts the magnetic glue of the magnetic capsule 7, and the magnetic capsule 7 adheres to the inner wall of the pipeline. The coil coupling magnetization assembly 100 is moved to drive the magnetic capsule 7 to move to the pipeline break; then the induction coil 3 is controlled to be energized to drive the heating coil 73 of the magnetic capsule 7 to generate current through electromagnetic induction. The heating coil 73 drives the coiled pipe 74 to heat up, melts the magnetic capsule 7, and releases the magnetic glue. Under the action of the electromagnetic coil 2, the magnetic glue adheres to the pipeline break, thereby completing the repair of the pipeline.

[0040] The above specific embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any other corresponding changes and deformations made according to the technical concept of the present invention should be included in the protection scope of the claims of the present invention.
