Description

Technical Field

[0001] The present invention relates to the technical field of earthquake early warning monitoring equipment, and in particular to an earthquake monitoring and early warning device and a use method thereof. Background Art

[0002] Earthquake monitoring refers to the monitoring and measurement of earthquake precursor anomalies and seismic activities before and after an earthquake occurs. Earthquake monitoring and early warning devices refer to earthquake monitoring instruments, facilities and equipment. There are three types of seismic wave propagation methods: longitudinal waves, transverse waves and surface waves. Longitudinal waves propagate quickly, causing the ground to vibrate up and down. Transverse waves propagate slowly, causing the ground to move forward and backward. Surface waves are mixed waves generated by the encounter of longitudinal waves and transverse waves on the surface, which are more destructive.

[0003] Common earthquake monitoring and early warning equipment is installed on the ground or in observation wells when in use. When there are falling rocks, vehicles driving, or construction nearby, the ground will vibrate, and the external vibration will affect the earthquake monitoring accuracy of the earthquake monitoring equipment, causing the earthquake monitoring equipment to misjudge the cause of the vibration. When in use, the earthquake monitoring equipment cannot be buried underground at a specified depth, and it is impossible to monitor the different seismic waves generated during an earthquake in real time. Summary of the invention

[0011] Preferably, a battery pack is installed on the inner wall of the tube body, and the battery pack is located above the mounting plate. A groove is provided on the top of the mounting plate, and a positioner is installed inside the groove.

[0012] Preferably, a thread is provided on the inner wall of the top end of the tube body, a top plate is installed on the inner wall of the tube body, the top plate is located below the thread, and a plurality of cleaning holes are obliquely provided on the inner wall of the tube body, the cleaning holes are located on the top side of the top plate.

[0013] Preferably, a circuit board is installed at the bottom of the top plate, and a plurality of L-shaped card blocks are installed at the bottom of the top plate near the edge, the edge of the circuit board is located inside the plurality of card blocks, and the battery pack is located between the mounting plate and the top plate.

[0014] Preferably, a connecting rod is installed at the top end of the tube body, the bottom end of the connecting rod is installed inside the tube body through a thread, and a screw hole is opened at the top end of the connecting rod.

[0015] A method for using an earthquake monitoring and early warning device in the present invention comprises the following steps:

[0016] Step 1: The staff installs the drill bit at the bottom of the pipe body, and installs a connecting rod of a specified length at the top of the pipe body. The top of the connecting rod is connected to the external transmission mechanism. The transmission mechanism drives the pipe body and the drill bit to rotate on the ground, so that the pipe body is drilled vertically into the ground as the drill bit rotates;

[0017] Step 2: When in use, the locator inside the pipe body can monitor the position of the pipe body underground in real time. When the pipe body is about to move down to the specified position, the staff stops the rotation of the pipe body through the external transmission mechanism and presses the pipe body down to make the pipe body move vertically underground;

[0018] Step 3: The electric slider drives the sliding plate to move, so that the sliding plate pushes the fixed plate and the rotating plate to rotate around the support rod, until the fixed plate and the outer wall of the tube body are perpendicular to each other, and the top end of the connecting rope is located in the limiting holes on the rotating plates;

[0019] Step 4: When an earthquake occurs on the ground, the locator can detect the amplitude of the ground vibration when the longitudinal wave of the earthquake occurs, and move the top of the connecting rope through the fixed plate and the rotating plate to make the gravity ball contact with the tactile sensor. When the transverse wave of the earthquake occurs, it will drive the tube body to move forward and backward, and also make the gravity ball on the connecting rope contact with the tactile sensor;

[0020] Step 5: When a slight earthquake occurs, several low-frequency sound wave detection pieces can detect the low-frequency sound waves generated by the earthquake. When in use, earthquakes are monitored in a variety of ways to improve the accuracy of earthquake monitoring. The pipe body is buried at a specified depth underground to reduce the impact of external ground vibrations on earthquake monitoring.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, the pipe body is installed at a position at a specified depth underground through a drill bit and a connecting rod. The drill bit 3 can drill holes in underground rocks or relatively hard land, which facilitates the pipe body 1 to move down to the specified depth. When the ground vibrates due to falling rocks, driving, construction, etc., the vibration amplitude of the ground will not affect the pipe body deeper underground, so that the pipe body can accurately monitor the vibration amplitude of the surrounding soil during an earthquake. When the pipe body is buried and installed, the pipe body is perpendicular to the ground. When the staff is burying the pipe body and the gravity ball is in contact with the tactile sensor for a long time, the staff can adjust the angle of the pipe body. When the pipe body is about to move down to the specified position, a plurality of fixed plates on the outer wall of the pipe body are unfolded, so that the fixed plate and the outer wall of the pipe body are perpendicular to each other. When in use, the plurality of fixed plates can play a better role in position limitation and support for the pipe body.

[0023] 2. In the present invention, as the plurality of rotating plates rotate during use, the top end of the connecting rope will move to the inside of the limiting holes on the plurality of rotating plates, and the limiting holes can play a better role in limiting the position of the top end of the connecting rope. The longitudinal waves generated during an earthquake will cause the ground to vibrate up and down, and will also drive the pipe body to vibrate up and down. The positioner located inside the pipe body can detect the amplitude of the up and down movement of the pipe body in real time. At the same time, when the pipe body vibrates up and down, the soil around the pipe body will push the fixed plate, and drive the rotating plate to rotate slightly. When the rotating plate rotates, the end of the connecting rope close to the mounting plate can be moved through the limiting hole, so that the connecting rope and the gravity ball at its bottom end can shake until the gravity ball contacts the tactile sensor, and the circuit board can transmit the information detected by the positioner and the tactile sensor to the outside world.

[0024] 3. In the present invention, the transverse waves generated during an earthquake will drive the pipe body and the surrounding soil to sway left and right through the ground. When the pipe body sways left and right, the connecting rope inside it and the gravity ball on it will swing inside the pipe body. At the same time, the gravity ball will reciprocate against the inner walls on both sides of the tactile sensor. When the pipe body sways left and right during use, the impact of the gravity ball on the tactile sensor is greater than the impact of the gravity ball on the tactile sensor when the pipe body sways up and down. The staff can cooperate with the locator according to the strength and frequency of the impact on the tactile sensor to detect the vibration amplitude of different seismic waves when the earthquake occurs, and can infer the location and intensity of the earthquake based on the interval time between the longitudinal wave and the transverse wave.

[0025] 4. In the present invention, when the staff needs to move the pipe body out of the ground for maintenance or position change, the bottom end of the connecting rod will push the soil inside the top of the pipe body, so that the soil inside the pipe body is gradually discharged to the outside of the pipe body through a number of cleaning holes. When in use, the soil at the top of the pipe body will not affect the connection between the connecting rod and the pipe body. The external transmission mechanism pulls the connecting rod and the pipe body to move upward, and a fixing groove is provided on the side of the fixing plate close to the end of the pipe body. Therefore, the position of the fixing plate close to the fixing groove is too weak. When the connecting rod and the pipe body move upward, the fixing plate close to the fixing groove will be broken. After the pipe body is disconnected from the fixing plate, the pipe body, the drill bit and the connecting rod can be gradually moved out to the ground. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] As a technical optimization solution of the present invention, a connecting rod 2 is installed at the top of the tube body 1, the bottom end of the connecting rod 2 is installed inside the tube body 1 through a thread 15, and a screw hole 7 is opened at the top of the connecting rod 2; when the staff completes the installation of the tube body 1, the staff can disassemble the connecting rod 2 at any time.

[0046] A method for using an earthquake monitoring and early warning device in the present invention comprises the following steps:

[0047] Step 1: The staff installs the drill bit 3 at the bottom end of the pipe body 1, and installs a connecting rod 2 of a specified length at the top end of the pipe body 1. The top end of the connecting rod 2 is connected to an external transmission mechanism. The transmission mechanism drives the pipe body 1 and the drill bit 3 to rotate on the ground, so that the pipe body 1 is vertically drilled into the ground as the drill bit 3 rotates;

[0048] Step 2: When in use, the positioner 17 located inside the pipe body 1 can monitor the position of the pipe body 1 underground in real time. When the pipe body 1 is about to move down to the specified position, the staff stops the rotation of the pipe body 1 through the external transmission mechanism and presses the pipe body 1 downward to make the pipe body 1 move vertically underground;

[0049] Step 3: The electric slider 31 drives the sliding plate 30 to move, so that the sliding plate 30 pushes the fixed plate 6 and the rotating plate 26 to rotate around the support rod 20, until the fixed plate 6 and the outer wall of the tube body 1 are perpendicular to each other, and the top end of the connecting rope 12 is located in the limiting holes 27 on the rotating plates 26;

[0050] Step 4: When an earthquake occurs on the ground, the locator 17 can detect the amplitude of the ground vibration when the longitudinal wave of the earthquake occurs, and move the top of the connecting rope 12 through the fixed plate 6 and the rotating plate 26 to make the gravity ball 13 contact with the tactile sensor 21. When the transverse wave of the earthquake occurs, it will drive the pipe body 1 to move forward and backward, and also make the gravity ball 13 on the connecting rope 12 contact with the tactile sensor 21;

[0051] Step 5: When a slight earthquake occurs, a number of low-frequency sound wave detection pieces 11 can detect the low-frequency sound waves generated during the earthquake. When in use, the earthquake is monitored in a variety of ways to improve the accuracy of earthquake monitoring. The pipe body 1 is buried at a specified depth underground to reduce the impact of external ground vibrations on earthquake monitoring.

[0052] When the present invention is in use, the staff installs the drill bit 3 at the bottom end of the pipe body 1. The bottom end of the pipe body 1 is conical, so after the drill bit 3 is installed, the bottom end of the pipe body 1 and the drill bit 3 are conical as a whole, which is convenient for the staff to move the pipe body 1 underground. The staff connects the top end of the pipe body 1 with the connecting rod 2 through the thread 15. When in use, the staff can install connecting rods 2 of different lengths according to the buried depth of the pipe body 1. The top end of the connecting rod 2 is connected to the external transmission mechanism, and the transmission mechanism drives the pipe body 1 and the drill bit 3 to rotate.

[0053] When in use, the drill bit 3 can drill holes in the ground and cooperate with the transmission mechanism to gradually move the pipe body 1 underground. The staff can understand the position of the pipe body 1 underground based on the locator 17 inside the pipe body 1. When the pipe body 1 is buried, the pipe body 1 is perpendicular to the ground, and the gravity ball 13 inside the pipe body 1 is inside the tactile sensor 21, but the gravity ball 13 does not contact the tactile sensor 21. When the staff is burying the pipe body 1 and the gravity ball 13 contacts the tactile sensor 21 for a long time, the staff can adjust the angle of the pipe body 1. When in use, the pipe body 1 is installed at a specified depth underground. When the ground vibrates due to falling rocks, driving, construction, etc., it will not affect the pipe body 1 deeper underground, so that the pipe body 1 can accurately monitor earthquakes.

[0054] When the pipe body 1 is about to move down to the designated position, the staff stops the transmission mechanism from rotating the pipe body 1 and the drill bit 3, and makes the transmission mechanism press down the connecting rod 2 and the pipe body 1, driving the pipe body 1 to move vertically downward underground. The staff can drive the sliding plate 30 to slide inside the installation groove 23 through the electric slider 31, and move one end of the sliding plate 30 to the inside of the placement groove 5. When in use, one end of the sliding plate 30 moves into the chamfer 25 on the fixed plate 6, and pushes the fixed plate 6, so that the fixed plate 6 drives the rotating plate 26 to rotate around the support rod 20, until the end of the fixed plate 6 close to the electric slider 31 moves out of the placement groove 5, and while the pipe body 1 moves down, the soil underground will push the fixed plate 6 close to one side of the placement groove 5, so that when the pipe body 1 moves down, the rotating plate 26 and the fixed plate 6 gradually rotate until the fixed plate 6 and the outer wall of the pipe body 1 are perpendicular to each other.

[0055] When the rotating plate 26 rotates, one end of the rotating plate 26 located inside the tube body 1 will gradually rotate toward the direction of the connecting rope 12. When in use, as the rotating plates 26 rotate, the top of the connecting rope 12 will move to the inside of the limiting holes 27 on the rotating plates 26. The limiting holes 27 can better limit the position of the top of the connecting rope 12. In front of the rotating plate 26, the fixed plate 6 and the rotating plate 26 can better block and seal the fixing hole 19. After the fixed plate 6 rotates, the middle end of the L-shaped rotating plate 26 can still seal the fixing hole 19 to prevent external soil from entering the interior of the tube body 1 during use. When in use, the battery pack 9, the circuit board 16, the positioner 17 and the touch sensor 21 are electrically connected to each other, and the circuit board 16 is connected to the outside world by electrical signals.

[0056] When an earthquake occurs, the longitudinal waves generated by the earthquake will cause the ground to vibrate up and down, and will also drive the pipe body 1 to vibrate up and down. The positioner 17 located inside the pipe body 1 can detect the amplitude of the up and down movement of the pipe body 1 in real time. At the same time, when the pipe body 1 vibrates up and down, the soil around the pipe body 1 will push the fixed plate 6 away from one end of the pipe body 1, causing the fixed plate 6 to rotate slightly up and down with the support rod 20 as the center, and at the same time drive the rotating plate 26 to rotate slightly. When the rotating plate 26 rotates, the end of the connecting rope 12 close to the mounting plate 8 can be moved through the limiting hole 27, so that the connecting rope 12 and the gravity ball 13 at its bottom end shake until the gravity ball 13 contacts the tactile sensor 21, and the circuit board 16 can transmit the information detected by the positioner 17 and the tactile sensor 21 to the outside world.

[0057] The transverse waves generated during an earthquake will drive the pipe body 1 and the surrounding soil to sway left and right through the ground. When the pipe body 1 sways left and right, the connecting rope 12 inside it and the gravity ball 13 thereon will swing inside the pipe body 1, and at the same time, the gravity ball 13 will reciprocate against the inner walls on both sides of the tactile sensor 21. When in use, the gravity ball 13 hits the tactile sensor 21 harder when the pipe body 1 sways left and right than when the pipe body 1 sways up and down. The staff can cooperate with the locator 17 according to the strength and frequency of the impact on the tactile sensor 21 to detect the vibration amplitude of different seismic waves when an earthquake occurs, and a number of low-frequency sound wave detection sheets 11 can detect the low-frequency sound waves generated during an earthquake, and can infer the location and intensity of the earthquake based on the interval between the longitudinal wave and the transverse wave.

[0058] When the staff needs to remove the pipe body 1 from the ground for maintenance or position change, the staff can position the pipe body 1 through the positioner 17, insert the connecting rod 2 into the ground, and move the bottom end of the connecting rod 2 toward the top end of the pipe body 1 until the bottom end of the connecting rod 2 is inserted into the top end of the pipe body 1. When the bottom end of the connecting rod 2 is installed inside the top end of the pipe body 1, the bottom end of the connecting rod 2 will push the soil inside the top end of the pipe body 1, so that the soil is squeezed and moved toward the top plate 10 inside the top end of the pipe body 1, and as the connecting rod 2 moves, the soil inside the pipe body 1 gradually passes through a number of cleaning holes 4 to the outside of the pipe body 1. When in use, the soil at the top end of the pipe body 1 will not affect the connection between the connecting rod 2 and the pipe body 1. The staff can then rotate the connecting rod 2 so that the bottom end of the connecting rod 2 is installed inside the pipe body 1 through the thread 15. When the staff rotates the connecting rod 2, because several fixing plates 6 on the outer wall of the pipe body 1 are installed in the soil around the pipe body 1, the pipe body 1 will not be driven to rotate underground when the connecting rod 2 rotates. The several fixing plates 6 can better limit the position of the pipe body 1, making it more convenient to connect the connecting rod 2 to the pipe body 1.

[0059] The staff can pull the connecting rod 2 and the pipe body 1 upward through the external transmission mechanism, and a fixing groove 28 is provided on the side of the fixing plate 6 near the end of the pipe body 1, so the position of the fixing plate 6 near the fixing groove 28 is too weak. When the connecting rod 2 and the pipe body 1 move upward, the fixing plate 6 near the fixing groove 28 will be broken, and after the pipe body 1 is disconnected from the fixing plate 6, the pipe body 1, the drill bit 3 and the connecting rod 2 can be gradually moved out to the ground. When in use, the function of the fixing plate 6 is mainly to drive the rotating plate 26 to rotate slightly through the vibration of the surrounding soil, thereby moving the connecting rope 12, and the material of the fixing plate 6 is a hard plastic plate, which is relatively low in cost. When several fixing plates 6 are broken into the ground, it will not cause excessive cost waste, and the hard plastic plate can still be used normally after being underground for a long time, and will not dissolve.

[0060] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.

A method for using an earthquake monitoring and early warning device as claimed in any one of claims 1 to 9, the method comprising the following steps: Step 1: The staff installs the drill bit (3) at the bottom end of the pipe body (1), and installs a connecting rod (2) of a specified length at the top end of the pipe body (1). The top end of the connecting rod (2) is connected to an external transmission mechanism, and the transmission mechanism drives the pipe body (1) and the drill bit (3) to rotate on the ground, so that the pipe body (1) is vertically drilled into the ground as the drill bit (3) rotates; Step 2: When in use, the positioner (17) located inside the pipe body (1) can monitor the position of the pipe body (1) underground in real time. When the pipe body (1) is about to move down to the specified position, the staff stops the rotation of the pipe body (1) through the external transmission mechanism and presses the pipe body (1) downward to make the pipe body (1) move vertically underground; Step 3: The electric slider (31) drives the sliding plate (30) to move, so that the sliding plate (30) pushes the fixed plate (6) and the rotating plate (26) to rotate around the support rod (20) until the fixed plate (6) and the outer wall of the tube body (1) are perpendicular to each other, and the top end of the connecting rope (12) is located in the limiting holes (27) on the plurality of rotating plates (26); Step 4: When an earthquake occurs on the ground, the locator (17) can detect the amplitude of the ground vibration when the longitudinal wave of the earthquake occurs, and move the top of the connecting rope (12) through the fixed plate (6) and the rotating plate (26) to make the gravity ball (13) contact with the tactile sensor (21). When the transverse wave of the earthquake occurs, it will drive the pipe body (1) to move forward and backward, and also make the gravity ball (13) on the connecting rope (12) contact with the tactile sensor (21); Step 5: When a slight earthquake occurs, a plurality of low-frequency sound wave detection pieces (11) can detect the low-frequency sound waves generated during the earthquake. When in use, the earthquake is monitored in a variety of ways to improve the accuracy of earthquake monitoring. The pipe body (1) is buried underground at a specified depth to reduce the impact of external ground vibrations on earthquake monitoring.
