[0012] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0013] The technical solution specifically implemented in this utility model is:

[0014] like Figure 1 As shown, a wireless communication repeater for underground pipeline space includes a first cylinder 1 and a second cylinder 2, the upper part of the first cylinder 1 is a large cylinder 3, a relay module 4 is arranged inside the large cylinder 3, the lower part of the first cylinder 1 is a small cylinder 5, a battery pack 6 is arranged inside the small cylinder 5, the relay module 4 is electrically connected to the battery pack 6, a first contact 7 is arranged on the bottom surface of the small cylinder 5, and the first contact 7 is electrically connected to the battery pack 6; a mounting groove 8 is provided at the bottom of the second cylinder 2, an electromagnet 9 extending to the outside of the lower cylinder is arranged in the mounting groove 8, a cylinder groove 10 is provided at the top of the second cylinder 2, the small cylinder 5 is slidably arranged in the cylinder groove 10, a second contact 11 is arranged on the inner bottom surface of the cylinder groove 10, the second contact 11 is arranged corresponding to the first contact 7 up and down, and the second contact 11 is electrically connected to the electromagnet 9.

[0015] A limiting slide groove 12 is provided on the inner side of the above-mentioned barrel groove 10, and a limiting protrusion 13 is provided on the bottom side of the small barrel portion 5, and the limiting protrusion 13 is slidably set in the limiting slide groove 12; in actual use, the small barrel portion 5 is prevented from completely escaping from the barrel groove 10, and the first barrel body 1 and the second barrel body 2 are completely separated.

[0016] The first contact 7 is a male contact, and the second contact 11 is a corresponding female contact groove, and the male contact is inserted into the female contact groove; in actual use, it is beneficial to the conductive connection between the first contact 7 and the second contact 11.

[0017] A hanging ring 14 is provided on the top of the first cylinder 1; in actual use, the hanging ring 14 facilitates the robot to retract and release the wireless communication repeater.

[0018] The outer diameters of the first cylinder and the second cylinder are equal, and the outer diameter of the small cylinder portion matches the inner diameter of the cylinder groove.

[0019] When in use, after the wireless communication repeater is placed at a preset position in the pipeline, the first cylinder 1 descends under the action of gravity, and the small cylinder portion 5 of the first cylinder 1 moves down along the limiting slide groove 12 in the cylinder groove 10 of the second cylinder 2, and the first contact 7 contacts the second contact 11, so that the electromagnet 9 is energized to generate electromagnetic attraction, and the wireless communication repeater is automatically adsorbed and fixed in the pipeline.
