Description

Technical Field

[0001] The present invention relates to the technical field of geological disaster early warning, and particularly relates to a geological disaster early warning device and method. Background Art

[0002] Geological disasters refer to geological processes or phenomena that cause losses to human life and property under the action of natural or human factors, mainly including earthquakes, landslides, debris flows, ground collapses, etc. Among them, an earthquake is the sudden release of accumulated tectonic stress under the action of internal and external stresses in the earth's crust, generating vibrating elastic waves that spread from the earthquake source to the surrounding areas, causing ground tremors. It is an extremely intense natural phenomenon. For mountainous areas, earthquakes not only cause serious damage to infrastructure such as buildings, roads, and bridges, but may even trigger mountain landslides, further exacerbating the casualties of people in the low-lying areas at the foot of the mountain. To avoid the phenomenon of mountain landslides caused by earthquakes, geological disaster early warning devices are usually set on the mountains to achieve the purpose of early warning, timely evacuation of people, and protection of the lives and safety of the people.

[0003] Currently, some common early warning devices monitor through sensors, mountain crack thresholds, etc. Since the device that predicts by monitoring the opening size of mountain cracks can only issue a warning during or after a landslide, in order to improve the effect of real-time and rapid response early warning, currently, early warning is mostly achieved through sensor early warning devices. The early warning device usually includes a device body, a bracket, and an anchor for anchoring the device body and the bracket to the mountain. Among them, a vibration sensor and a displacement sensor are usually arranged inside the body to monitor the vibration and displacement changes of the strata respectively. Then, by transmitting the monitored data to the main control machine, the main control machine controls the buzzer to issue an early warning signal. The existing early warning devices usually use the data of detecting the transverse wave intensity of an earthquake and the offset amount of the displacement sensor itself relative to the origin position in the horizontal direction to send signals to the main control machine. However, the existing early warning devices have a warning lag when monitoring geological disasters. Because although the longitudinal wave in an earthquake is weaker than the transverse wave in intensity, the propagation speed of the longitudinal wave is faster than that of the transverse wave. The existing early warning devices can only rely on the stronger longitudinal wave to detect vibration and displacement, and it is difficult to achieve the effect of quickly responding and issuing an early warning signal during a real earthquake. Secondly, for the current early warning devices, false early warnings are likely to occur under external interferences such as extreme weather or accidental collisions by animals. Summary of the Invention

[0004] The present invention provides a geological disaster early warning device, which can achieve rapid response during a real earthquake and avoid false early warning signals caused by external interferences such as extreme strong wind and heavy rain weather or accidental collisions caused by animals rolling stones.

[0005] The present invention provides a geological disaster warning device, which includes two triggers, two pulling ropes, and a counterweight body fixedly connected to the middle parts of the two pulling ropes. Each trigger includes: two boxes, two torsion springs connected in the boxes, two yaw assemblies, and a plurality of electromagnetic sensing transceiver modules. The two boxes are respectively placed in the soil layer and rock layer of the mountain body. An opening is formed on one side of the two boxes facing each other. Two coaxial rotating shafts are horizontally rotatably connected in each box. Each torsion spring is sleeved and fixedly connected to the corresponding rotating shaft. The upper and lower ends of the two pulling ropes are respectively fixedly connected to the torsion springs above and below one by one. The counterweight body is placed in the cavity between the two boxes. The two yaw assemblies are respectively placed in the two boxes. Each yaw assembly includes two swing wheels rotatably connected to the box through a wheel shaft and a plurality of elastic sliding members slidably inserted along the axial direction of the swing wheel. The wheel shaft and the rotating shaft are connected through a synchronous rotation assembly. A gap is left between the two swing wheels. The plurality of electromagnetic sensing transceiver modules are respectively connected to the outer ends of the elastic sliding members. As the two swing wheels rotate, the elastic sliding members are thrown out by inertia, so that the electromagnetic sensing transceiver modules close to each other send the electromagnetic intensity data of mutual induction into the main control machine for sending out warning signals.

[0006] Preferably, the axes of the two wheel shafts in the same box are on the same horizontal plane.

[0007] Preferably, a housing is sleeved outside each torsion spring. An opening for the pulling rope to pass through is formed on one side of the housing close to the opening of the box. The two torsion springs at the same height are symmetrical to each other.

[0008] Preferably, the synchronous rotation assembly includes: a first pulley, a second pulley, and a synchronous belt. The first pulley is fixedly sleeved on the rotating shaft, the second pulley is fixedly sleeved on the wheel shaft, and the synchronous belt is wound around and connected to the first pulley and the second pulley.

[0009] Preferably, a plurality of blind holes are formed on the circumferential direction of the swing wheel. The elastic sliding member includes: a sliding rod, a counterweight ball, and a return spring. The sliding rod is slidably connected in the blind hole. The counterweight ball is made of metal and is fixedly connected to the end of the sliding rod outside the blind hole. One end of the return spring is fixedly connected to the counterweight ball, and the other end is fixedly connected to the inner wall of the blind hole for resetting the sliding displacement of the sliding rod.

[0010] Preferably, the electromagnetic sensing transceiver module includes an electromagnetic inductor and an electromagnetic signal transceiver. The electromagnetic signal transceiver is electrically connected to the main control machine.

[0011] Preferably, a fixed box is sleeved on the pulling rope close to the counterweight body. The fixed box is fixed between the soil layer and the rock layer of the mountain body. The counterweight ball is placed in the middle of the fixed box. A circular inner cavity is formed inside the fixed box. A distance sensor is arranged in the inner cavity for on-line monitoring of the position offset of any degree of freedom of the counterweight body. A signal transmitter for sending data signals to the main control machine is arranged on the fixed box.

[0012] Preferably, guide wheels are rotatably connected to both sides of the two pulling ropes corresponding to the opening of each box body, and the pulling ropes are placed between the corresponding two guide wheels.

[0013] Preferably, the box body placed in the upper soil layer is connected to the support through a connecting rod.

[0014] The present invention also provides a monitoring method for a geological disaster warning device, including the following steps:

[0015] S1. During an earthquake, the counterweight undergoes a longitudinal offset in the cavity between the two box bodies under the longitudinal wave of the earthquake. As the counterweight moves longitudinally, it drives the two pulling ropes to synchronously displace vertically.

[0016] S2. When the two pulling ropes move downward, the pulling ropes pull the two torsion springs at a higher position downward. At the same time, the two torsion springs below contract synchronously. When the two pulling ropes move upward, the pulling ropes pull the two torsion springs at a lower position upward. At the same time, the two torsion springs above contract synchronously. At this time, each rotating shaft rotates simultaneously, and each rotating shaft drives the wheel shaft to rotate synchronously through the first belt pulley, the second belt pulley, and the belt. Each swing wheel rotates with the corresponding wheel shaft.

[0017] S3. Each sliding rod in the swing wheel slides out of the blind hole under the action of the counterweight ball and the rotational centrifugal force. The electromagnetic sensors on the two swing wheels that are close to each other sense the electromagnetic intensity, and thus the data signal of the intensity is fed back and sent to the main control machine through the electromagnetic signal transceiver.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: This early warning device can convert the energy of the shear wave into an early warning data signal, and relying on the prerequisite that the propagation speed of the longitudinal wave is faster than that of the shear wave, it preferentially converts the relatively weak energy of the longitudinal wave into a data signal that triggers the main control machine to issue an early warning, thereby achieving the beneficial effect of rapid response during a real earthquake. At the same time, this early warning device can also achieve the beneficial effect of converting kinetic energy into an electrical data signal and sending it to the main control machine and promptly issuing an early warning signal under the vibration environment where the soil layer and the rock layer have different directions and frequencies caused by the longitudinal wave of the earthquake. By placing two triggers, a counterweight, etc. in the mountain stratum, it can avoid false triggering of the early warning signal caused by external interferences such as extreme strong wind and heavy rain weather or animals, gravel rollers, etc. Specifically, during an earthquake, the counterweight undergoes longitudinal reciprocating displacement in the cavity between the two boxes under the action of the longitudinal wave of the earthquake. Due to the counterweight having a certain gravity, it drives the two pulling ropes to synchronously displace vertically relying on its gravity and inertia. When the two pulling ropes move downward, the pulling ropes pull the two upper torsion springs downward. At the same time, the two lower torsion springs contract synchronously. When the two pulling ropes move upward, the pulling ropes pull the two lower torsion springs upward. At the same time, the two upper torsion springs contract synchronously. At this time, each rotating shaft rotates at a high speed, and each rotating shaft drives the wheel shafts of the respective swing wheels to rotate synchronously through a synchronous rotation assembly. Each swing wheel rotates with the corresponding wheel shaft. Each sliding rod in the swing wheel slides out of the blind hole under the action of the counterweight ball and the rotational centrifugal force. The electromagnetic sensors on the two swing wheels that are close to each other sense the electromagnetic intensity, and thus the data signal of this intensity is fed back and sent to the main control machine through the electromagnetic signal transceiver.

[0019] Under the vibration environment where the soil layer and the rock layer have different directions and frequencies caused by the longitudinal wave of the earthquake, the relative positions of the two boxes shift. At this time, relying on the pulling ropes, the internal torsion springs can still be continuously tightened, thereby triggering the rotation of the swing wheels, and then using the electromagnetic sensing and transceiver module to sense the electromagnetic intensity and promptly feedback it to the main control machine to achieve the real-time issuance of the early warning signal.

Therefore, it should not be construed as a limitation to the present invention.

[0028] Refer to Figure 1 、 Figure 2 and Figure 3, the present invention provides a geological disaster warning device, which includes two triggers 1, two pulling ropes 2, and a counterweight 3 fixedly connected to the middle of the two pulling ropes 2. The trigger 1 includes: two boxes 11, two torsion springs 12 connected inside the box 11, two yaw assemblies 14, and a plurality of electromagnetic sensing transceiver modules 15. The two boxes 11 are respectively placed in the soil layer a and the rock layer b of the mountain. An opening is provided on the opposite side of the two boxes 11. Two coaxial rotating shafts 13 are horizontally rotatably connected inside each box 11. Each torsion spring 12 is sleeved and fixedly connected to the corresponding rotating shaft 13. The upper and lower ends of the two pulling ropes 2 are respectively fixedly connected to the upper and lower torsion springs 12 in a one-to-one correspondence. The counterweight 3 is placed in the cavity between the two boxes 11. The two yaw assemblies 14 are respectively placed in the two boxes 11. The yaw assembly 14 includes two swing wheels 142 rotatably connected to the box 11 through a wheel shaft 141 and a plurality of elastic sliding members 143 axially slidably inserted along the swing wheel 142. The wheel shaft 141 is connected to the rotating shaft 13 through a synchronous rotation assembly 144. A gap is left between the two swing wheels 142. A plurality of electromagnetic sensing transceiver modules 15 are respectively connected to the outer ends of the elastic sliding members 143. As the two swing wheels 142 rotate, the elastic sliding members 143 are thrown out by inertia, so that the corresponding electromagnetic sensing transceiver modules 15 close to each other send the electromagnetic intensity data that can be mutually sensed into the main control machine c for sending out a warning signal.

[0029] In the above embodiments, the warning device can convert the shear wave energy into warning data signals. Relying on the prerequisite that the propagation speed of the longitudinal wave is faster than that of the shear wave, it preferentially converts the relatively weak energy of the longitudinal wave into the data signal for triggering the main controller c to issue a warning, so as to achieve the beneficial effect of rapid response during an actual earthquake. At the same time, the warning device can still convert kinetic energy into electrical data signals and send them to the main controller c under the vibration environment where the soil layer a and the rock layer b have different directions and frequencies caused by the longitudinal wave of the earthquake, and achieve the beneficial effect of timely sending of warning signals. By placing the two triggers 1, the counterweight 3, etc. in the bottom layer of the mountain, it can avoid false triggering of warning signals caused by external interferences such as extreme strong wind and rain weather or animal gravel rollers. Specifically, during an earthquake, the counterweight 3 undergoes longitudinal reciprocating displacement in the cavity between the two boxes 11 under the action of the longitudinal wave of the earthquake. Due to the certain gravity of the counterweight 3 itself, it drives the two pulling ropes 2 to move vertically synchronously by relying on its gravity and inertia. When the two pulling ropes 2 move downward, the pulling ropes 2 pull down the two spiral springs 12 at a higher position. At the same time, the two spiral springs 12 below contract synchronously. When the two pulling ropes 2 move upward, the pulling ropes 2 pull up the two spiral springs 12 at a lower position. At the same time, the two spiral springs 12 above contract synchronously. At this time, each rotating shaft 13 rotates at a high speed. Each rotating shaft 13 drives the axle 141 of each swing wheel 142 to rotate through the synchronous rotation assembly 144. Each swing wheel 142 rotates along with the corresponding axle 141. Each sliding rod 1431 in the swing wheel 142 slides out of the blind hole 1421 under the action of the counterweight ball 1432 and the rotational centrifugal force. The electromagnetic sensors on the two swing wheels 142 that are close to each other sense the electromagnetic intensity, and thus feedback and send the data signal of this intensity to the main controller c through the electromagnetic signal transceiver.

[0030] Under the vibration environment where the longitudinal wave of the earthquake causes the soil layer a and the rock layer b to have different directions and frequencies, the relative positions of the two boxes 11 shift. At this time, relying on the pulling rope 2, the internal spiral springs 12 can still be continuously tightened, thereby triggering the rotation of the swing wheel 142, and then using the electromagnetic sensing and transceiver module 15 to sense the electromagnetic intensity and timely feedback it to the main controller c to achieve the real-time sending of warning signals.

[0031] Further, referring to Figure 2 , considering more accurate and stable sensing of the electromagnetic intensity, in this embodiment, the axes of the two axles 141 in the same box 11 are located on the same horizontal plane.

[0032] Further, referring to Figure 4 , a housing 5 is sleeved outside each spiral spring 12. An opening for the pulling rope 2 to pass through is provided on one side of the housing 5 close to the opening of the box 11. The two spiral springs 12 at the same height are symmetric with each other.

[0033] In the above embodiments, in order to accurately guide and limit the coil spring 12 and the pulling rope 2, the provided housing 5 can wrap the coil spring 12, and the pulling rope 2 only passes through the opening of the housing 5.

[0034] Further, referring to Figure 4 , the synchronous rotation assembly 144 includes: a first pulley 1441, a second pulley 1442, and a synchronous belt 1443. The first pulley 1441 is fixedly sleeved on the rotating shaft 13, the second pulley 1442 is fixedly sleeved on the wheel shaft 141, and the synchronous belt 1443 is wound around and connected to the first pulley 1441 and the second pulley 1442.

[0035] In the above embodiments, the provided first pulley 1441 and second pulley 1442 can achieve the effect of synchronously driving the rotation of the rotating shaft 13 and the wheel shaft 141. Further, the outer diameter of the first pulley 1441 fixedly connected to the rotating shaft 13 is larger than the outer diameter of the second pulley 1442 fixedly connected to the wheel shaft 141, thereby realizing the amplification adjustment of the rotation speed of the wheel shaft 141, and when an earthquake occurs, the response is faster.

[0036] Further, referring to Figure 3 , a plurality of blind holes 1421 are formed in the circumferential direction of the swing wheel 142. The elastic sliding member 143 includes: a sliding rod 1431, a counterweight ball 1432, and a return spring 1433. The sliding rod 1431 is slidably connected in the blind hole 1421. The counterweight ball 1432 is made of metal and is fixedly connected to the end of the sliding rod 1431 outside the blind hole 1421. One end of the return spring 1433 is fixedly connected to the counterweight ball 1432, and the other end is fixedly connected to the inner wall of the blind hole 1421 for resetting the sliding displacement of the sliding rod 1431.

[0037] In the above embodiments, relying on the weight of the counterweight ball 1432 being greater than the weight of the sliding rod 1431, the sliding rod 1431 is driven to slide out along the blind hole 1421 during the high-speed rotation of the swing wheel 142.

[0038] Further, referring to Figure 2 and Figure 3 , the electromagnetic sensing transceiver module 15 includes an electromagnetic inductor and an electromagnetic signal transceiver, and the electromagnetic signal transceiver is electrically connected to the main control machine c.

[0039] In the above embodiments, this electrical connection can be achieved through a wire. Further, this embodiment also provides a component capable of protecting the wire. This component includes a sleeve made of rubber material. The upper and lower ends of the sleeve are fixedly connected to the upper and lower boxes 11 respectively, and the pulling rope 2 is placed in the sleeve, thereby achieving a sealing effect and following the movement depending on the rubber material after stretching.

[0040] Further, referring to Figure 2, a fixing box 6 is sleeved on the pulling rope 2 near the counterweight 3. The fixing box 6 is fixed between the soil layer a and the rock layer b of the mountain body. The counterweight ball 1432 is placed in the middle of the fixing box 6. A circular inner cavity is opened inside the fixing box 6, and a distance sensor 7 is arranged in the inner cavity for on-line monitoring of the position deviation of any degree of freedom of the counterweight 3. A signal transmitter 8 for sending data signals to the main control machine c is arranged on the fixing box 6.

[0041] In the above embodiments, through the arranged fixing box 6 and the distance sensor 7, secondary sensing monitoring can be carried out in cooperation with the deviation of the counterweight 3. The distance sensor 7 will send the deviation amount of any degree of freedom of the sphere to the main control machine c through the signal transmitter 8, so as to realize a more accurate warning signal sending comprehensively. When an earthquake occurs, the longitudinal wave causes the longitudinal displacement of the counterweight 3. At this time, the distance sensor 7 can sense the distance between the counterweights 3 and send signals in real time. When the transverse wave of the earthquake appears or even the soil layer a landslides, the counterweight 3 will still swing horizontally.

[0042] Further, referring to Figure 3 , at the openings of each box body 11, guide wheels 9 are rotatably connected to both sides corresponding to the two pulling ropes 2, and the pulling ropes 2 are placed between the corresponding two guide wheels 9.

[0043] In the above embodiments, the arranged guide wheels 9 can play a beneficial role in guiding and supporting the displacement of the pulling ropes 2.

[0044] Further, referring to Figure 1 , the box body 11 placed in the upper soil layer a is connected to the bracket through a connecting rod.

[0045] In the above embodiments, both sides of the bracket are fixed to the mountain body through a plurality of anchor rods extending into the mountain body.

[0046] The present invention also provides a monitoring method for a geological disaster warning device, including the following steps:

[0047] S1. During an earthquake, the counterweight 3 undergoes longitudinal deviation in the cavity between the two box bodies 11 under the longitudinal wave of the earthquake. As the counterweight 3 undergoes longitudinal displacement, it drives the two pulling ropes 2 to synchronously displace vertically;

[0048] S2. When the two pulling ropes 2 move downward, the pulling ropes 2 pull the two upper spiral springs 12 downward. At the same time, the two lower spiral springs 12 contract synchronously. When the two pulling ropes 2 move upward, the pulling ropes 2 pull the two lower spiral springs 12 upward. At the same time, the two upper spiral springs 12 contract synchronously. At this time, each rotating shaft 13 rotates simultaneously. Each rotating shaft 13 drives the wheel shaft 141 to rotate synchronously through the first belt pulley 1441, the second belt pulley 1442, and the belt synchronous belt 1443. Each swing wheel 142 rotates with the corresponding wheel shaft 141;

[0049] S3. Each sliding rod 1431 in the swing wheel 142 slides out of the blind hole 1421 under the action of the counterweight ball 1432 and the rotational centrifugal force. The electromagnetic sensors on the two swing wheels 142 that are close to each other sense the electromagnetic intensity, and thus feedback and send the data signal of the intensity to the main controller c by relying on the electromagnetic signal transceiver;

[0050] Further, when an earthquake occurs, its longitudinal wave causes the longitudinal displacement of the counterweight 3. At this time, the distance sensor 7 can sense the distance of the counterweight 3 and send signals in real time. When the transverse wave of the earthquake appears or even a landslide of the soil layer a occurs, the counterweight 3 will still swing horizontally.

[0051] The above only discloses several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be thought of by those skilled in the art should fall within the protection scope of the present invention.
