The upper shell 1 is located on the top of the well lid 100, and the lower shell 2 is located on the bottom of the well lid 100. At least one through hole 101 is formed on the well lid 100, and the connecting mechanism 3 is connected with the upper shell 1 and the lower shell 2 through the through hole 101. The signal receiver 4 is arranged in the upper shell 1, and the chip assembly 5 is arranged in the lower shell 2.

The chip assembly 5 is connected with the signal receiver 4 through the wire passing through the connecting mechanism 3, that is, the 4G signal and the Beidou signal under the well are effectively transmitted to the ground, so that the 4G signal and the Beidou signal can be transmitted to the ground base station for further analysis and use.

[0038] Further, the connecting mechanism 3 comprises a connecting column 31, a connecting nut 32 and a connecting screw, the bottom of the connecting column 31 is provided with a thread, the top end face of the lower shell 2 is provided with a threaded hole, the thread is matched with the threaded hole, the signal receiver 4 is welded with one end of the wire, the other end of the wire extends to the bottom of the connecting column 31 through the hollow cavity of the connecting column 31, and the other end of the wire can be inserted into the receiving port of the chip assembly 5. The top of the connecting column 31 is integrally formed with the upper shell 1, and the connecting column 31 is fixed to the well lid 100 through the connecting nut 32 and the connecting screw. The connection mode is convenient to install and operate, and the signal transmission efficiency is greatly improved.

[0039] Further, the positioning structure 6 is further provided. The positioning structure 6 comprises a positioning pin seat 61 welded to the inner wall of the well chamber, the positioning pin seat 61 extends along the radial direction of the well lid 100 and is arranged towards the connecting column 31, an annular insertion hole 62 with an opening is formed at one end of the positioning pin seat 61 close to the connecting column 31, the positioning structure 6 further comprises a steel ring 63 sleeved on the connecting column 31, the steel ring 63 is fixedly provided with an "L"-shaped connecting rod 64, the "L"-shaped connecting rod 64 can be inserted into the annular insertion hole 62, and an arc-shaped movable baffle 65 is further arranged at the opening of the annular insertion hole 62. When the "L"-shaped connecting rod 64 is inserted into the annular insertion hole 62, the arc-shaped movable baffle 65 can extend along the circumference of the annular insertion hole 62 to close the opening. The arrangement of the positioning structure 6 can effectively prevent the lower shell 2 and the connecting column 31 from loosening and falling after long-term use. It should be noted that the arrangement of the arc-shaped movable baffle 65 closes the opening to prevent the "L"-shaped connecting rod 64 from rotating in the circumferential direction, thereby preventing the connecting column 31 from rotating relative to the lower shell 2, and thereby reasonably fixing the connecting column 31.

[0040] Further, the positioning structure 6 further comprises a driving member 66 at the bottom of the inner circle of the annular insertion hole 62, a transmission member 67 arranged in the inner circle of the annular insertion hole 62, and a sliding sheet 68 slidably installed on the annular insertion hole 62, and the sliding sheet 68 is fixedly connected with the arc-shaped movable baffle 65. The driving member 66 is connected with the transmission member 67, the transmission member 67 can slide along the circumferential direction of the inner circle of the annular insertion hole 62, the sliding sheet 68 is distributed along the radial direction of the annular insertion hole 62, and the side close to the inner diameter of the sliding sheet 68 penetrates through the annular insertion hole 62 and is connected with the transmission member 67. The driving mode is simple in structure, easy to realize, compact in space structure, and does not affect the use of the remaining structure.

[0041] Further, the driving member 66 is a servo motor, and the servo motor receives start and stop signals wirelessly. The transmission member 67 is an annular gear ring 671 with the same size as the inner circle of the annular insertion hole 62 and a driving gear 672 connected with the servo motor. The operation is simple, and the transmission force is more direct.

[0042] It is also necessary to point out that through the positioning structure 6, the "L" shaped connecting rod 64 can be locked by automatic driving after the well lid 100 is installed to the well chamber, thereby preventing the connecting column 31 from loosening.

The arc-shaped end cover 12 can be suitable for the passing of different vehicles on the ground. And the support partitions 13 made of steel arranged on the planar base plate 11 can prevent the support effect of the upper shell 1 from being improved when the vehicles pass.
