When the device is in a damp and corrosive underground environment for a long time, the internal components are prone to failure due to moisture or corrosion, which significantly shortens the overall service life of the earthquake early warning monitoring device.

[0005] In a first aspect, this invention provides an earthquake monitoring device with an early warning function, specifically comprising: a transmission connector, a seismic detector, a rotating sleeve, a sliding sleeve, a small sealing ring, a protective upper cap, a large sealing ring, a protective lower shell, a sliding ring, and a positioning pin; the top of the transmission connector is connected to a data acquisition and early warning station on the ground via a wire, and the bottom of the transmission connector is connected to the seismic detector, which is located at a depth of 50-150 meters underground; the transmission connector is externally fitted with a rotating sleeve and a sliding sleeve, with the sliding sleeve located on top of the rotating sleeve and connected to the seismic detector; the seismic detector is externally fitted with a small sealing ring, and the seismic detector is externally connected to a protective upper cap, which is located on top of the small sealing ring; a large sealing ring is installed inside the protective upper cap, and the bottom of the protective upper cap is connected to a protective lower shell, with the seismic detector located inside the protective lower shell; the protective lower shell is externally fitted with a sliding ring, which is connected to the protective upper cap.

[0006] Furthermore, the top of the seismic detector is provided with a plug, which is inserted into the transmission connector. Connecting blocks are symmetrically arranged on the outside of the plug, and straight connection slots are symmetrically arranged on the outside of the transmission connector. The connecting blocks are connected to the straight connection slots.

[0007] Furthermore, the rotating sleeve is rotatably connected to the transmission connector, and two L-shaped slots are arranged around the outside of the rotating sleeve. The L-shaped slots are connected to the straight connection slots, and the connecting block is connected in the L-shaped slots.

[0008] Furthermore, the sliding sleeve is slidably connected to the transmission connector, and fixed blocks are symmetrically arranged on the outside of the transmission connector, while sliding holes are symmetrically arranged inside the sliding sleeve, with the fixed blocks slidably connected within the sliding holes.

[0009] Furthermore, the top of the rotating sleeve is symmetrically provided with limiting grooves, and the bottom of the sliding sleeve is symmetrically provided with limiting blocks, which are inserted into the limiting grooves.

[0010] Furthermore, a small spring is fitted outside the transmission connector, with the top of the small spring contacting the transmission connector and the bottom of the small spring contacting the top of the sliding sleeve.

[0011] Furthermore, the transmission connector is surrounded by a guide groove, the protective cap is slidably connected to the transmission connector, the protective cap is surrounded by a guide block, the guide block is slidably connected in the guide groove, the bottom side of the small sealing ring contacts the transmission connector, and the top side of the small sealing ring contacts the protective cap.

[0012] Furthermore, the inner side of the lower protective shell contacts the outer side of the seismic detector, the top of the lower protective shell is threaded into the upper protective cap, the top side of the large sealing ring contacts the upper protective cap, and the bottom side of the large sealing ring contacts the lower protective shell.

[0013] Furthermore, the protective cap is symmetrically provided with positioning grooves on its outer surface, and the protective lower shell is symmetrically provided with sliding grooves on its outer surface. The sliding grooves are connected to the positioning grooves, and the sliding ring is slidably connected to the protective lower shell. The top of the sliding ring is symmetrically provided with positioning pins, which are slidably connected in the sliding grooves, and the top of the positioning pins is slidably inserted into the positioning grooves.

[0014] Furthermore, a large spring is fitted on the top of the protective lower shell, with the bottom of the large spring in contact with the protective lower shell and the top of the large spring in contact with the sliding ring.

[0015] This invention provides an earthquake monitoring device with early warning function, which has the following beneficial effects:

[0016] In use, the seismic detector converts seismic waves into electrical signals, which are transmitted to the data acquisition and early warning station via a transmission connector. This provides timely early warning before high-intensity seismic waves reach the ground, reducing personal and property losses. When the plug is inserted into the transmission connector to establish the transmission line connection, the connecting block moves to the innermost end of the straight connection slot. At this time, the connecting block is located at the turning position of the L-shaped slot. Rotating the rotating sleeve moves the connecting block to the innermost end of the L-shaped slot, which limits the connection of the connecting block. The rotating sleeve fixes the seismic detector, ensuring the firmness of the connection between the seismic detector and the transmission connector, and making the disassembly and maintenance of the seismic detector easier in the future.

[0017] Furthermore, when the connecting block moves to the innermost end of the L-shaped slot, the limiting groove is located directly below the limiting block. The sliding sleeve moves downward under the influence of the small spring, causing the limiting block to insert into the limiting groove, thus locking and fixing the rotating sleeve. This effectively prevents the rotating sleeve from rotating in the opposite direction and ensures the fixing effect of the rotating sleeve on the seismic detector. When the seismic detector malfunctions and needs to be disassembled for repair or replacement, the rotating sleeve is moved upward, the small spring contracts under force, the limiting block separates from the limiting groove, the rotating sleeve is unlocked, and the rotating sleeve can be rotated in the opposite direction to move the connecting block to the turning position of the L-shaped slot. The connecting block is then released from its limiting position, and the seismic detector can be disassembled from the bottom of the transmission connector. The operation is simple and quick.

[0018] In addition, a small sealing ring seals the connection between the protective cap and the transmission connector, while a large sealing ring seals the connection between the protective cap and the lower protective shell. This keeps the internal seismic detector dry, effectively preventing corrosion from groundwater vapor and extending its service life. When the protective cap and the lower protective shell are threaded together, the sliding groove and the positioning groove are connected. The lower protective shell moves and resets under the thrust of the large spring, causing the end of the positioning pin to insert into the positioning groove, thus limiting the lower protective shell and effectively preventing loosening of the threaded connection between the protective cap and the lower protective shell, ensuring the sealing and protection of the internal seismic detector. When it is necessary to separate the lower protective shell from the protective cap, the sliding ring is moved downwards, the end of the positioning pin separates from the positioning groove, the lower protective shell is released from its limiting position, and the lower protective shell can be rotated in the opposite direction to separate it from the protective cap.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the described embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please refer to Figures 1 to 8 Example 1:

[0035] This invention proposes an earthquake monitoring device with early warning function, comprising: a transmission connector 1, a seismic detector 2, a rotating sleeve 3, a sliding sleeve 4, a small sealing ring 6, a protective upper cap 7, a large sealing ring 8, a protective lower shell 9, a sliding ring 10, and a positioning pin 1001; the top of the transmission connector 1 is connected to a data acquisition and early warning station on the ground via a wire, and the bottom of the transmission connector 1 is connected to the seismic detector 2, which is located at a depth of 50-150 meters underground; the transmission connector 1 is externally fitted with a rotating sleeve 3 and a sliding sleeve 4, with the sliding sleeve 4 located on top of the rotating sleeve 3, and the rotating sleeve 3 connected to the seismic detector 2; the seismic detector... The seismic detector 2 is externally fitted with a small sealing ring 6, and externally connected to a protective cap 7, which is located on top of the small sealing ring 6. A large sealing ring 8 is installed inside the protective cap 7, and a protective lower shell 9 is connected to the bottom of the protective cap 7, with the seismic detector 2 located inside the protective lower shell 9. A sliding ring 10 is fitted externally to the protective lower shell 9, and the sliding ring 10 is connected to the protective cap 7. When an earthquake occurs, the seismic detector 2 converts the seismic waves into electrical signals, which are transmitted to the data acquisition and early warning station via the transmission connector 1. This provides timely early warning before high-intensity seismic waves reach the ground, reducing personal and property losses.

[0036] In this embodiment, the top of the seismic detector 2 is provided with a plug 201, which is inserted into the transmission connector 1. Connecting blocks 2011 are symmetrically arranged on the outside of the plug 201. A straight connection groove 101 is symmetrically arranged on the outside of the transmission connector 1. The connecting blocks 2011 are connected to the straight connection groove 101. The rotating sleeve 3 is rotatably connected to the transmission connector 1. Two L-shaped slots 301 are arranged around the outside of the rotating sleeve 3. The L-shaped slots 301 are connected to the straight connection groove 101. The connecting blocks 2011 are connected to the L-shaped slots 301.

[0037] Using the above technical solution, when the plug 201 is inserted into the transmission connector 1 to connect the transmission line, the connecting block 2011 moves to the innermost end of the straight connection slot 101. At this time, the connecting block 2011 is located at the turning position of the L-shaped slot 301. By rotating the rotating sleeve 3, the connecting block 2011 is moved to the innermost end of the L-shaped slot 301, which has the effect of limiting the connecting block 2011. The rotating sleeve 3 fixes the seismic detector 2, ensuring the firmness of the connection between the seismic detector 2 and the transmission connector 1, making the disassembly and maintenance of the seismic detector 2 easier in the future.

[0038] In this embodiment, the sliding sleeve 4 is slidably connected to the transmission connector 1. The transmission connector 1 is symmetrically provided with fixed blocks 102 on the outside. The sliding sleeve 4 is symmetrically provided with sliding holes 401 inside. The fixed blocks 102 are slidably connected in the sliding holes 401. The top of the rotating sleeve 3 is symmetrically provided with limiting grooves 302. The bottom of the sliding sleeve 4 is symmetrically provided with limiting blocks 402. The limiting blocks 402 are inserted into the limiting grooves 302. The transmission connector 1 is fitted with a small spring 5 on the outside. The top of the small spring 5 contacts the transmission connector 1, and the bottom of the small spring 5 contacts the top of the sliding sleeve 4.

[0039] Using the above technical solution, when the connecting block 2011 moves to the innermost end of the L-shaped slot 301, the limiting slot 302 is located directly below the limiting block 402. The sliding sleeve 4 moves downward under the influence of the small spring 5, so that the limiting block 402 is inserted into the limiting slot 302, which plays a role in locking and fixing the rotating sleeve 3, effectively preventing the rotating sleeve 3 from rotating in the opposite direction and ensuring the fixing effect of the rotating sleeve 3 on the seismic detector 2. When the seismic detector 2 malfunctions and needs to be disassembled for repair and replacement, the rotating sleeve 3 is moved upward, the small spring 5 is compressed under force, the limiting block 402 separates from the limiting slot 302, the rotating sleeve 3 is unlocked, and the rotating sleeve 3 can be rotated in the opposite direction, so that the connecting block 2011 moves to the turning position of the L-shaped slot 301, the connecting block 2011 is released from the limit, and the seismic detector 2 can be disassembled from the bottom of the transmission connector 1. The operation is simple and quick.

[0040] In Example 2, based on Example 1, a guide groove 103 is provided around the outside of the transmission connector 1, the protective cap 7 is slidably connected to the transmission connector 1, a guide block 701 is provided around the inside of the protective cap 7, the guide block 701 is slidably connected in the guide groove 103, the bottom side of the small sealing ring 6 contacts the transmission connector 1, the top side of the small sealing ring 6 contacts the protective cap 7, the inner side of the protective lower shell 9 contacts the outer side of the seismic detector 2, the top of the protective lower shell 9 is threadedly connected to the protective cap 7, the top side of the large sealing ring 8 contacts the protective cap 7, and the bottom side of the large sealing ring 8 contacts the protective lower shell 9.

[0041] By adopting the above technical solution, the connection between the protective cap 7 and the transmission connector 1 is sealed by the small sealing ring 6, and the connection between the protective cap 7 and the protective lower shell 9 is sealed by the large sealing ring 8, so that the internal seismic detector 2 is kept dry, effectively preventing groundwater vapor from corroding it and extending the service life of the seismic detector 2.

[0042] In this embodiment, the protective cap 7 is symmetrically provided with positioning grooves 702 on the outside, and the protective lower shell 9 is symmetrically provided with sliding grooves 901 on the outside. The sliding grooves 901 are connected to the positioning grooves 702. The sliding ring 10 is slidably connected to the protective lower shell 9. The top of the sliding ring 10 is symmetrically provided with positioning pins 1001. The positioning pins 1001 are slidably connected in the sliding grooves 901. The top of the positioning pins 1001 is slidably inserted into the positioning grooves 702. The top of the protective lower shell 9 is fitted with a large spring 11. The bottom of the large spring 11 is in contact with the protective lower shell 9, and the top of the large spring 11 is in contact with the sliding ring 10.

[0043] Using the above technical solution, when the upper protective cap 7 and the lower protective shell 9 are threaded together, the slide groove 901 and the positioning groove 702 are in a connected state. The lower protective shell 9 moves and resets under the influence of the large spring 11, so that the end of the positioning pin 1001 is inserted into the positioning groove 702, which has the effect of limiting the lower protective shell 9 and effectively preventing the threaded connection between the upper protective cap 7 and the lower protective shell 9 from loosening, thus ensuring the sealing and protection effect of the internal seismic detector 2. When it is necessary to separate the lower protective shell 9 from the upper protective cap 7, the slide ring 10 is moved downward, the end of the positioning pin 1001 is separated from the positioning groove 702, the lower protective shell 9 is released from the limit, and the lower protective shell 9 can be rotated in the opposite direction to separate the lower protective shell 9 from the upper protective cap 7.

[0044] The working principle of this embodiment is as follows: First, the plug 201 is inserted into the transmission connector 1 to establish the transmission line connection. The connecting block 2011 is moved to the innermost end of the straight connection slot 101. At this time, the connecting block 2011 is located at the turning position of the L-shaped slot 301. The rotating sleeve 3 is rotated to move the connecting block 2011 to the innermost end of the L-shaped slot 301, which has a limiting effect on the connecting block 2011. The rotating sleeve 3 fixes the seismic detector 2, ensuring the firmness of the connection between the seismic detector 2 and the transmission connector 1. When the connecting block 2011 moves to the innermost end of the L-shaped slot 301, the limiting slot 302 is located directly below the limiting block 402. The sliding sleeve 4 moves downward under the influence of the small spring 5, so that the limiting block 402 is inserted into the limiting slot 302, which has a locking and fixing effect on the rotating sleeve 3, effectively preventing the rotating sleeve 3 from rotating in the opposite direction and ensuring the fixing effect of the rotating sleeve 3 on the seismic detector 2. Next, the protective cap 7 and the protective lower shell 9 are threaded together, and the protective cap 7 is secured by the small sealing ring 6. The connection between the upper protective cap 7 and the lower protective shell 9 is sealed, and the connection between the upper protective cap 7 and the lower protective shell 9 is sealed by the large sealing ring 8, keeping the internal seismic detector 2 dry and effectively preventing corrosion from groundwater vapor. After the upper protective cap 7 and the lower protective shell 9 are threaded together, the slide groove 901 and the positioning groove 702 are in communication. The lower protective shell 9 moves and resets under the influence of the large spring 11, so that the end of the positioning pin 1001 is inserted into the positioning groove 702, which has a limiting effect on the lower protective shell 9 and effectively prevents the threaded connection between the upper protective cap 7 and the lower protective shell 9 from loosening, ensuring the sealing and protection effect of the internal seismic detector 2. The seismic detector 2 is lowered to a depth of 50 to 150 meters underground. When an earthquake occurs, the seismic detector 2 converts the seismic waves into electrical signals and transmits them to the data acquisition and early warning station through the transmission connector 1. It provides timely early warning before high-intensity seismic waves reach the ground, reducing personnel and property losses.
