The terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the invention.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This invention provides a highly reliable microseismic monitor, such as... Figures 1-6 As shown, the high-reliability microseismic monitor includes: a microseismic monitor body 1; a base 2, with mounting holes at the center of the upper and lower surfaces of the base, the lower half of the microseismic monitor body being fixedly connected to the mounting hole, and the base being hollow; an annular sleeve 8, located inside the base and fitted onto the outer circumference of the microseismic monitor body, with an opening at the top; an injection port 9, located on the upper surface of the base and communicating with the top of the annular sleeve; several release holes 5, located at the bottom of the annular sleeve; and several through holes 11, located on the lower surface of the base and distributed along the annular sleeve. Below the sleeve; a flexible absorbent part 3, which is adapted to the through hole and partially exposed outside the through hole, the through hole having a certain height, i.e., the lower surface of the base having a certain thickness; two spiral rods 4 rotatably mounted on the bottom of the base 2 and symmetrically distributed about the annular sleeve, the tops of the two spiral rods extending upward into smooth rods, the tops of the smooth rods connecting to the upper surface of the base; a drive mechanism 10 disposed on the upper surface of the base 2, the drive mechanism being used to drive one spiral rod 4 to rotate; a main gear 7, the gear being sleeved on the smooth rods of the two spiral rods; and a secondary gear 6, the secondary gear being sleeved on the outer circumferential surface of the annular sleeve and meshing with the main gear.

[0022] In this embodiment, the microseismic monitor body 1 is a cylindrical structure, two spiral rods 4 are rotatably installed at the bottom of the base 2, and can drive two main gears, a secondary gear through a driving mechanism, and then drive the two spiral rods to rotate synchronously. The design of the spiral rod allows it to further penetrate the soil or rock layer when needed, achieving a more secure fixing effect. This adjustable fixing method enables the monitor to adapt to different geological conditions, improving the flexibility and stability of the installation. The design of the driving mechanism simplifies the adjustment process of the spiral rod, allowing the operator to easily control the depth of the spiral rod and quickly achieve stable installation of the monitor. The coupling agent is injected into the annular sleeve through the injection port, and the coupling agent enters the through hole through the release hole, wetting the flexible water absorption part. While rotating the spiral rod, the bottom of the flexible water absorption part first deforms in contact with the soil or rock layer, releasing the coupling agent to the gap between the microseismic monitor body and the soil or rock layer, ensuring that the coupling agent can fill the gap and enhance wave conduction, thereby allowing the monitor to better receive microseismic signals. This structure allows the coupling agent to be accurately released between the microseismic monitor body and the soil or rock layer, and the flexible water absorption part can intermittently receive the coupling agent from the annular sleeve. When the release hole is aligned with the through hole, the coupling agent flows into the flexible water absorption part. When the release hole is completely misaligned with the through hole, the coupling agent is blocked, greatly improving the utilization rate of the coupling agent and avoiding waste.

[0023] In a further preferred embodiment of the present application, the flexible water absorption part is fixed in the through hole. Specifically, a screen can be provided in the through hole, and the flexible water absorption part is filled in the screen. In this way, the flexible water absorption part is prevented from falling out of the through hole. The flexible water absorption part is preferably made of materials such as sponge and cotton that rely on cavities to absorb water.

[0024] In a further preferred embodiment of the present application, a photovoltaic power supply mechanism is also included. The photovoltaic power supply mechanism includes an L-shaped plate 12 fixedly installed on the upper surface of the base 2, two vertical plates 13 fixedly installed on the top of the horizontal section of the L-shaped plate 12, a horizontal shaft 14 rotatably installed between the two vertical plates 13, a rotating plate 15 fixedly sleeved on the horizontal shaft 14, and a solar cell 16 fixedly installed on the rotating plate 15. The solar cell is electrically connected to the driving mechanism.

[0025] In this embodiment, the solar cell converts solar energy into electrical energy to supply the driving mechanism, which is an electric motor that drives the spiral rod to rotate.

[0026] In a further preferred embodiment of the present application, a stepping motor 17 is fixedly installed at the bottom of the horizontal section of the L-shaped plate 12. The output shaft of the stepping motor 17 is rotatably connected to the horizontal section of the L-shaped plate. A driving bevel gear 18 is fixedly installed on the output shaft of the stepping motor 17. A driven bevel gear 19 is fixedly sleeved on the horizontal shaft 14. The driving bevel gear 18 is engaged with the driven bevel gear 19.

[0027] In the embodiment, the horizontal shaft 14 can be driven to rotate by the stepping motor 17, the driving bevel gear 20 and the driven bevel gear 19, and the solar cell 16 can be driven to rotate by the rotating plate 15, so that the angle of the solar cell 16 is adjusted.

[0028] In several embodiments provided in the present application, it should be understood that the disclosed device can be implemented by other ways.

[0029] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit the protection scope of the present application.
