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

[0024] Please see the appendix Figures 1-6 This utility model discloses an antenna structure for an underground pipeline detector, including a reading terminal 1 and an antenna mechanism 4, as well as an antenna mounting base 2 and an antenna protection mechanism 3, wherein:

[0025] The antenna mounting base 2 is installed at the bottom of the reading terminal 1 via a conduit, and the antenna protection mechanism 3 is detachably installed at the bottom of the antenna mounting base 2;

[0026] The antenna protection mechanism 3 includes a protective cylinder 31, and the antenna mechanism 4 includes a detection antenna 42. The detection antenna 42 is enclosed in the protective cylinder 31. The top of the detection antenna 42 is equipped with a connecting seat 41 that can be detachably installed at the bottom of the antenna mounting base 2. The bottom of the protective cylinder 31 is equipped with a lifting plate 32 that cooperates with the detection antenna 42 and can be raised and lowered.

[0027] Please refer to the appendix. Figure 2 , Figure 4 , Figure 5 , Figure 6 The antenna mounting base 2 has an annular threaded groove 25 at the bottom, and the outer wall of the top of the protective cylinder 31 has an external thread corresponding to the threaded groove 25. Multiple support legs 33 are symmetrically installed on the outer wall of the bottom of the protective cylinder 31.

[0028] Specifically, hold the protective cylinder 31 and rotate it counterclockwise to disengage the bottom of the protective cylinder 31 from the threaded groove 25 at the bottom of the antenna mounting base 2, thus disassembling the protective cylinder 31. Similarly, move the protective cylinder 31 upwards, put the detection antenna 42 on the protective cylinder 31, and then rotate the protective cylinder 31 clockwise to screw the top of the protective cylinder into the bottom interface of the antenna mounting base 2 to install the protective cylinder 31.

[0029] Furthermore, the antenna mounting base 2 is symmetrically provided with through mounting holes 21 located in the threaded groove 25, and the top of the connecting base 41 is symmetrically provided with screw seats 46. The screw seats 46 are internally threaded with mounting screws 22. The antenna mounting base 2 and the connecting base 41 are fixedly connected by the mounting screws 22 passing through the mounting holes 21 and entering the screw seats 46.

[0030] Specifically, the detection antenna 42 can be removed from the antenna mounting base 2 by unscrewing the mounting screw 22 from the top of the antenna mounting base 2.

[0031] It should be noted that when unscrewing the mounting screw 22, the detection antenna 42 should be supported to prevent it from falling and being damaged after the mounting screw 22 is removed.

[0032] Furthermore, the antenna mounting base 2 has an annular positioning groove 23 with a radius smaller than the threaded groove 25 installed at its bottom. The positioning groove 23 is located inside the threaded groove 25. A positioning ring 44 is installed on the top of the connecting base 41. The positioning ring 44 is movably connected to and fits the positioning groove 23. The antenna mounting base 2 has symmetrically arranged arc-shaped locking grooves 24 at its bottom. The locking grooves 24 are located inside the positioning groove 23. Arc-shaped locking pins 45 are symmetrically installed on the top of the connecting base 41. The locking pins 45 are movably connected to and fit the locking grooves 24. U-shaped control handles 47 are symmetrically installed on the bottom of the connecting base 41. The control handles 47 are offset from the screw seat 46 and are enclosed by the protective sleeve 31.

[0033] Specifically, when installing the detection antenna 42, align the locking pin 45 on the connector 41 with the locking groove 24 at the bottom of the antenna mounting base 2, and then move the detection antenna 42 upward. The detection antenna 42 drives the connector 41 upward so that the positioning ring 44 and the locking pin 45 on the connector 41 are inserted into the positioning groove 23 and the locking groove 24 respectively. This allows for precise positioning and fixation of the detection antenna 42. By controlling the handle 47, the detection antenna 42 can be held and kept stable without touching the antenna. Example 2

[0034] Please refer to the appendix. Figure 2 , Figure 3A spring 34 is installed at the bottom of the protective cylinder 31. The bottom surface of the lifting plate 32 is fixedly connected to the top of the spring 34. A circular transmission base 43 is installed at the bottom of the detection antenna 42. The transmission base 43 is movably connected to the protective cylinder 31. The lifting plate 32 is located at the bottom of the transmission base and cooperates with the transmission base 43.

[0035] In this embodiment, after the protective cylinder 31 moves upward and the detection antenna 42 is placed on the protective cylinder 31, the protective cylinder 31 is rotated clockwise so that the top of the protective cylinder is screwed into the threaded groove 25 at the bottom of the antenna mounting base 2. Under the action of the spring 34, the lifting plate 32 at the bottom of the protective cylinder 31 moves upward and presses against the transmission base 43, so that the detection antenna 42 on the transmission base 43 remains stable.

[0036] The working principle and usage process of this utility model are as follows: When replacing the detection antenna 42, hold the protective sleeve 31 and rotate it counterclockwise so that the bottom of the protective sleeve 31 is disengaged from the threaded groove 25 at the bottom of the antenna mounting base 2. Then, move the protective sleeve 31 vertically downward until the detection antenna 42 is fully exposed, thus completing the disassembly of the protective sleeve 31. Then, unscrew the mounting screw 22 from the top of the antenna mounting base 2. It should be noted that when unscrewing the mounting screw 22, the detection antenna 42 needs to be supported to prevent it from falling and being damaged after the mounting screw 22 is removed. At this time, move the detection antenna 42 downward and remove it to complete the disassembly of the detection antenna 42.

[0037] Place the connector 41 on the new detection antenna 42 upwards at the bottom of the antenna mounting base 2. Then align the locking pin 45 on the connector 41 with the locking groove 24 at the bottom of the antenna mounting base 2. Then move the detection antenna 42 upwards, which will cause the connector 41 to move upwards so that the positioning ring 44 and the locking pin 45 on the connector 41 are inserted into the positioning groove 23 and the locking groove 24 respectively. Then screw the assembly screw 22 through the assembly hole 21 into the screw seat 46 to fix the detection antenna 42.

[0038] Finally, move the protective cylinder 31 upward to fit the detection antenna 42 inside the protective cylinder 31, and then rotate the protective cylinder 31 clockwise so that the top of the protective cylinder is screwed into the threaded groove 25 at the bottom of the antenna mounting base 2 to fix the protective cylinder 31. During this process, the lifting plate 32 at the bottom of the protective cylinder 31 moves upward under the action of the spring 34 to press against the transmission base 43, so that the detection antenna 42 on the transmission base 43 remains stable.
