[0035] For better explaining the present invention and facilitating understanding, the present invention will be described in detail below in conjunction with the drawings through specific implementation modes.

[0036] Refer to Figures 1-6 As shown, a signal transmission system for a well chamber includes a signal transmission device for a well chamber. The signal transmission device for a well chamber includes an upper shell 1, a lower shell 2 and a connection mechanism 3. The upper shell 1 is located at the top of the manhole cover 100, the lower shell 2 is located at the bottom of the manhole cover 100, at least one through hole 101 is opened on the manhole cover 100, and the upper and lower ends of the connection mechanism 3 pass through the through hole 101 and are respectively connected to the upper shell 1 and the lower shell 2. A signal receiver 4 is arranged in the upper shell 1, a chip assembly 5 is arranged in the lower shell 2, the chip assembly 5 is connected to the signal receiver 4 through a wire, and the wire passes through the connection mechanism 3. The chip assembly 5 is used for processing signals underground, and the signal receiver 4 is used for receiving the processed signals and transmitting them to the ground above the well.

[0037] In this embodiment, a through hole 101 is opened on the manhole cover 100, and the transmission device is installed in the manhole cover 100 through the through hole 101. The signal transmission device for the well chamber installs the upper shell 1 and the lower shell 2 on the upper and lower sides of the manhole cover 100 respectively by setting the connection mechanism 3, and the chip assembly 5 is installed in the lower shell 2, the signal receiver 4 is installed in the upper shell 1, and the chip assembly 5 is connected to the signal receiver 4 through a wire passing through the connection mechanism 3, that is, the 4G signal and Beidou signal underground are effectively transmitted to the ground, so that the 4G signal and Beidou signal can be transmitted to the base station on the ground for further analysis and use.

[0038] Further, the connecting mechanism 3 includes a connecting cylinder 31, a connecting nut 32 and a connecting screw. The bottom of the connecting cylinder 31 is provided with a thread, and a threaded hole is opened at the top end face of the lower shell 2. The thread is screwed with the threaded hole in a matching manner. The signal receiver 4 is welded to one end of a wire, and the other end of the wire passes through the hollow chamber of the connecting cylinder 31 and extends to the bottom of the connecting cylinder 31. The other end of the wire can be inserted into the receiving port of the chip assembly 5. The top of the connecting cylinder 31 is integrally formed with the upper shell 1, and the connecting cylinder 31 is fixed to the manhole cover 100 through the connecting nut 32 and the connecting screw. This connection method is convenient for installation and operation and greatly improves the signal transmission efficiency.

[0039] Further, a positioning structural member 6 is also included. The positioning structural member 6 includes a positioning pin seat 61 welded to the inner wall of the well chamber. The positioning pin seat 61 extends towards the connecting cylinder 31 along the radial direction of the manhole cover 100. An annular jack 62 with an opening is opened at one end of the positioning pin seat 61 close to the connecting cylinder 31. The positioning structural member 6 further includes a steel ring 63 sleeved on the connecting cylinder 31. An "L"-shaped connecting rod 64 is fixedly arranged on the steel ring 63. The "L"-shaped connecting rod 64 can be inserted into the annular jack 62. An arc-shaped movable baffle 65 is also arranged at the opening of the annular jack 62. When the "L"-shaped connecting rod 64 is inserted into the annular jack 62, the arc-shaped movable baffle 65 can extend along the circumference of the annular jack 62 to close the opening. The setting of this positioning structural member 6 can effectively prevent the problem that the lower shell 2 and the connecting cylinder 31 become loose and then fall off during long-term use. It should also be noted that the setting of the arc-shaped movable baffle 65 closes the opening to prevent the "L"-shaped connecting rod 64 from rotating circumferentially, thereby preventing the connecting cylinder 31 from rotating relative to the lower shell 2, and thus reasonably fixing the connecting cylinder 31.

[0040] Further, the positioning structural member 6 further includes a driving member 66 located at the bottom of the inner ring of the annular jack 62, a transmission member 67 arranged in the inner ring of the annular jack 62, and a sliding piece 68 that can be slidably installed on the annular jack 62. The sliding piece 68 is fixedly connected to the arc-shaped movable baffle 65. The driving member 66 is connected to the transmission member 67. The transmission member 67 can slide along the circumference of the inner ring of the annular jack 62. The sliding piece 68 is distributed along the radial direction of the annular jack 62, and the side of the sliding piece 68 close to the inner diameter passes through the annular jack 62 and is connected to the transmission member 67. This driving method has a simple structure, is easy to implement, has a compact space structure, and does not affect the use of other structures.

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

[0042] It should also be noted that after the manhole cover 100 is installed in the well chamber through the positioning structural member 6, the "L"-shaped connecting rod 64 can be locked in an automatic driving manner, thereby preventing the connecting column body 31 from loosening.

[0043] Furthermore, the upper shell 1 includes an integrally formed flat chassis 11 and an arc-shaped end cover 12. A plurality of support partition plates 13 are arranged at intervals on the flat chassis 11, and the support partition plates 13 extend vertically upward to the arc-shaped end cover 12. A space for placing the signal receiver 4 is formed between adjacent support partition plates 13. The arc-shaped end cover 12 can be suitable for the passage of different vehicles on the ground. And the support partition plates 13 made of steel material are arranged on the flat chassis 11, which can improve the support effect of the upper shell 1 when the vehicle passes by.

[0044] Furthermore, both the arc-shaped end cover 12 and the flat chassis 11 are made of hard plastic material to ensure the effective transmission of signals.
