Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of earthquake monitoring and warning equipment, and particularly relates to an earthquake monitoring and warning device and a use method thereof. BACKGROUND

[0002] Earthquake monitoring refers to monitoring and measuring earthquake precursors and seismic activity before and after an earthquake, and an earthquake monitoring and warning device refers to earthquake monitoring instruments, facilities and equipment. There are three methods of earthquake wave propagation: P-wave, S-wave and surface wave. P-wave propagates at high speed, causing the ground to vibrate up and down, S-wave propagates at a slower speed, causing the ground to move forward and backward, and surface wave is a mixed wave generated by the encounter of P-wave and S-wave on the ground, which has great destructive power.

[0003] Common earthquake monitoring and warning equipment is installed on the ground or in an observation well during use. When falling rocks, vehicle driving or nearby construction occur in the external environment, the ground will vibrate, and the external vibration will affect the earthquake monitoring accuracy of the earthquake monitoring and warning equipment, resulting in misjudgment of the cause of the vibration by the earthquake monitoring and warning equipment. The earthquake monitoring and warning equipment cannot be buried in a specified depth of the ground during use, and cannot monitor different earthquake waves generated during an earthquake in real time.

[0020] Step five: when a slight earthquake occurs, the plurality of low-frequency sound detection sheets can detect the low-frequency sound generated during the earthquake, and the accuracy of earthquake monitoring is improved by monitoring the earthquake in multiple ways during use, and the pipe body is buried in the ground at a specified depth, thereby reducing the influence of external ground vibration on earthquake monitoring.

[0021] Compared with the prior art, the beneficial effects of the present application are:

[0022] 1、The pipe body in the application is installed at a specified depth in the ground through a drill bit and a connecting rod, the drill bit 3 can drill holes in underground rocks or relatively hard soil, facilitating the downward movement of the pipe body 1 to the specified depth, and the vibration amplitude of the ground will not affect the pipe body in the ground when the ground vibrates due to falling rocks, driving, construction, etc., so that the pipe body can accurately monitor the vibration amplitude of the surrounding soil during an earthquake, and when the pipe body is being installed, the gravity ball can be adjusted when the gravity ball is in contact with the tactile sensor for a long time, and the angle of the pipe body can be adjusted when the pipe body is about to be moved to the specified position, and the plurality of fixed plates on the outer wall of the pipe body are expanded so that the fixed plates are perpendicular to the outer wall of the pipe body, and the plurality of fixed plates can better limit and support the position of the pipe body during use.

[0023] 2、In the application, the top end of the connecting rope moves to the inside of the limiting hole on the rotating plate during use, and the plurality of limiting holes can better limit the position of the top end of the connecting rope, the longitudinal wave generated during the earthquake will cause the ground to vibrate up and down, and the pipe body will also vibrate up and down, and the locator inside the pipe body can detect the amplitude of the up and down movement of the pipe body in real time, and 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, and the connecting rope can be pushed by the limiting hole when the rotating plate rotates, so that the connecting rope and the gravity ball at the bottom end of the connecting rope are shaken until the gravity ball contacts the tactile sensor, and the circuit board can transmit the information detected by the locator and the tactile sensor to the outside.

[0024] 3、The transverse wave generated during the earthquake can drive the pipe body and the surrounding soil to sway left and right through the ground, and when the pipe body sways left and right, the connecting rope inside the pipe body and the gravity ball thereon will swing inside the pipe body, and the gravity ball will reciprocally collide with the two sides of the inner wall of the tactile sensor.

[0025] 4、When the staff needs to remove the pipe body from the ground for maintenance or position replacement, the bottom end of the connecting rod pushes the soil inside the top end of the pipe body, so that the soil inside the pipe body gradually passes through the cleaning holes and is discharged to the outside of the pipe body.

[0046] The use method of the earthquake monitoring and early warning device in the present application comprises the following steps:

[0047] Step one: the worker installs a drill bit 3 on the bottom end of the pipe body 1, and installs a connecting rod 2 of a specified length on the top end of the pipe body 1, the top end of the connecting rod 2 is connected with a transmission mechanism outside, the transmission mechanism drives the pipe body 1 and the drill bit 3 to rotate on the ground, and the pipe body 1 is vertically drilled into the ground along with the rotation of the drill bit 3;

[0048] Step two: the positioner 17 located in the pipe body 1 can monitor the position of the pipe body 1 in the ground in real time during use, when the pipe body 1 is about to move to a specified position, the worker stops the rotation of the pipe body 1 through the transmission mechanism outside, and presses the pipe body 1 downward, so that the pipe body 1 moves vertically into the ground;

[0049] Step three: the electric sliding block 31 drives the sliding plate 30 to move, so that the sliding plate 30 drives the fixed plate 6 and the rotating plate 26 to rotate around the support rod 20 as the center, until the fixed plate 6 is perpendicular to the outer wall of the pipe body 1, and the top end of the connecting rope 12 is located in the limiting hole 27 on the rotating plate 26;

[0050] Step four: when the ground appears earthquake, the locator 17 can detect the up and down vibration amplitude of the ground when the seismic longitudinal wave, and through the fixed plate 6 and the rotating plate 26, the top end of the connecting rope 12 is pulled, so that the gravity ball 13 contacts the tactile sensor 21, and when the seismic transverse wave appears, the pipe body 1 is moved forward and backward, and the gravity ball 13 on the connecting rope 12 also contacts the tactile sensor 21;

[0051] Step five: when a slight earthquake occurs, the low-frequency sound detection sheet 11 can detect the low-frequency sound generated during the earthquake, and in use, the earthquake is monitored in multiple ways to improve the accuracy of earthquake monitoring, and the pipe body 1 is buried in the ground at a specified depth, reducing the influence of external ground vibration on earthquake monitoring.

[0052] In use, the staff installs the drill bit 3 at the bottom end of the pipe body 1, and the bottom end of the pipe body 1 is conical, so after installing the drill bit 3, the bottom end of the pipe body 1 and the drill bit 3 are conical as a whole, which facilitates the staff to move the pipe body 1 to the ground. The staff connects the connecting rod 2 at the top end of the pipe body 1 through the thread 15, and in use, the staff can install connecting rods 2 of different lengths according to the depth of the pipe body 1 buried. The top end of the connecting rod 2 is connected with the transmission mechanism outside, and the pipe body 1 and the drill bit 3 are driven to rotate through the transmission mechanism.

[0053] 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, and the staff can understand the position of the pipe body 1 underground through the locator 17 inside the pipe body 1. When installing the pipe body 1, 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 installs the pipe body 1, if the gravity ball 13 contacts the tactile sensor 21 for a long time, the staff can adjust the angle of the pipe body 1. In use, the pipe body 1 is installed at a specified depth underground, and when the ground vibrates due to falling stones, driving, construction and other reasons, it will not affect the pipe body 1 underground, so that the pipe body 1 can accurately monitor the earthquake.

[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 down vertically underground. The staff can drive the sliding plate 30 to slide in the installation groove 23 by the electric sliding block 31, and move one end of the sliding plate 30 into the placement groove 5. 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, making the fixed plate 6 drive the rotating plate 26 to rotate around the support rod 20 until the end of the fixed plate 6 close to the electric sliding block 31 moves out of the placement groove 5. When the pipe body 1 moves down, the soil underground pushes the side of the fixed plate 6 close to the placement groove 5, making the rotating plate 26 and the fixed plate 6 gradually rotate until the fixed plate 6 is perpendicular to the outer wall of the pipe body 1.

[0055] When the rotating plate 26 rotates, the end of the rotating plate 26 inside the pipe body 1 also gradually rotates towards the connecting rope 12. In use, with the rotation of the several rotating plates 26, the top end of the connecting rope 12 moves into the limiting hole 27 on the several rotating plates 26, and the several limiting holes 27 can better limit the position of the top end of the connecting rope 12. Before the rotating plate 26, the fixed plate 6 and the rotating plate 26 can better block and seal the fixed hole 19. After the fixed plate 6 rotates, the middle end of the L-shaped rotating plate 26 can still seal the fixed hole 19, preventing the soil outside from entering the inside of the pipe body 1 in use. In use, the battery pack 9, the circuit board 16, the locator 17 and the tactile sensor 21 are electrically connected with each other, and the circuit board 16 is electrically connected with the outside.

[0056] When an earthquake occurs, the longitudinal wave generated during the earthquake will make the ground vibrate up and down, and also drive the pipe body 1 to vibrate up and down. The locator 17 inside the pipe body 1 can detect the amplitude of the up-and-down movement of the pipe body 1 in real time. When the pipe body 1 vibrates up and down, the soil around the pipe body 1 pushes the end of the fixed plate 6 away from the pipe body 1, making the fixed plate 6 rotate up and down slightly around the support rod 20, and driving the rotating plate 26 to rotate slightly. When the rotating plate 26 rotates, the limiting hole 27 can push the end of the connecting rope 12 close to the installation plate 8, making the connecting rope 12 and the gravity ball 13 at the bottom end of the connecting rope 12 shake until the gravity ball 13 contacts the tactile sensor 21. The circuit board 16 can transmit the information detected by the locator 17 and the tactile sensor 21 to the outside.

[0057] The shear waves generated during an earthquake will drive the pipe body 1 and the surrounding soil to swing left and right through the ground. When the pipe body 1 swings left and right, the connecting rope 12 inside it and the gravity ball 13 on it will swing inside the pipe body 1. At the same time, the gravity ball 13 will collide back and forth with the inner walls on both sides of the tactile sensor 21. When in use, the gravity ball 13 hits the tactile sensor 21 when the pipe body 1 swings left and right more strongly than when the pipe body 1 swings up and down. The staff can cooperate with the locator 17 according to the force and frequency of the impact on the tactile sensor 21 to detect the vibration amplitude of different seismic waves when an earthquake occurs. In addition, several low-frequency sound wave detection pieces 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 time between the longitudinal wave and the shear wave.

[0058] When the staff needs to remove the pipe body 1 from the ground for maintenance or relocation, the staff can use the positioner 17 to position the pipe body 1, 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, causing the soil to be squeezed and moved toward the top plate 10 inside the top end of the pipe body 1. As the connecting rod 2 moves, the soil inside the pipe body 1 is gradually discharged to the outside of the pipe body 1 through the several cleaning holes 4. During 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 rotation of the connecting rod 2 will not drive the pipe body 1 to rotate underground. 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 and the pipe body 1.

[0059] The staff can use the external transmission mechanism to pull the connecting rod 2 and the pipe body 1 upward. The side of the fixing plate 6 near the end of the pipe body 1 is provided with a fixing groove 28. Therefore, 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 break. After the pipe body 1 and the fixing plate 6 are disconnected, 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 by the vibration of the surrounding soil, thereby moving the connecting rope 12. The material of the fixing plate 6 is a hard plastic plate, which is relatively low in cost. When several fixing plates 6 break and fall underground, it will not cause excessive cost waste. Moreover, the hard plastic plate can still be used normally after being underground for a long time without dissolving.

[0060] The above description is only the preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent substitutions or changes according to the technical solution and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
