Description

Technical Field

[0001] The present application belongs to the technical field of alarm devices, and in particular relates to an early warning device for landslide disasters and a method of using the same. Background Art

[0002] Early warning of landslides usually relies on irregular inspections by personnel and measurement of the relative displacement of the landslide body. This method cannot obtain 24-hour data information, which easily leads to defects such as untimely data updates and insufficient warning time for personnel to evacuate. With the development of Internet of Things technology, early warning devices for landslide disasters have gradually developed into automatic monitoring methods. By arranging multiple detection points on the mountain, the base station detects the real-time position information of multiple detection points and analyzes and calculates the displacement. When the set threshold is reached, a warning is issued through various methods such as broadcasting, sound and light alarms, and base station text messages.

[0003] The existing Chinese patent with publication number CN114283561A discloses a landslide geological disaster early warning device, which includes a vertical pole and a cone head fixedly connected to the lower end of the vertical pole for being embedded in the ground.

[0004] Although the above-mentioned early warning device can realize landslide early warning, its early warning function is only one-time. When other situations such as strong winds, human collisions, etc. cause the vertical pole to shake, the permanent magnet block will also come into contact with the magnetic induction module, issuing an early warning signal. When maintaining later, although the detection box can be reused, it still needs to be manually reset, which increases labor intensity. Summary of the Invention

[0005] The purpose of this application is to address the above-mentioned technical problems and provide an early warning device for landslide disasters, which can realize automatic and manual control to reset the detection mechanism of the early warning device to ensure reuse after false triggering.

[0006] The present application provides an early warning device for landslide disasters, comprising an early warning device body and several detection boxes placed in the early warning device body, wherein the detection boxes include:

[0007] Magneto-induction module;

[0008] A communication module is electrically connected to the magneto-induction module;

[0009] A detection mechanism is installed in the detection box, and the detection mechanism includes a rotating shaft, a rotating ring, a swing rod, and a permanent magnet block;

[0010] An abutment seat is installed in the detection box, and the abutment seat is provided with a plurality of evenly arranged abutment seats, and the lengths thereof are gradually increased;

[0011] A reset assembly, used to reset the swing rod to abut against the abutment seat, the reset assembly comprising a drive structure, a reset seat, and a reset spring;

[0012] A buffer device is placed on the reset seat and is adapted to the swing rod;

[0013] The magnetic induction module is placed on one side of the detection mechanism, the abutment seat is placed on the other side of the detection box, and the reset spring is placed between the reset seat and the detection box.

[0014] The magnetic induction module and the communication module are installed in the detection box. When the early warning device body shakes or tilts, the detection mechanism in the detection box is affected, causing the swing rod to rotate around the rotating shaft, and the permanent magnet acts on the magnetic induction module. The magnetic induction module generates an electrical signal and transmits it to the communication module. However, when the early warning device body is only subjected to severe shaking and no landslide disaster occurs, the early warning signal of the detection box can also be triggered, and the early warning device body without landslide disaster can continue to be used. All the swing rods are reset by the reset component so that all the swing rods are abutted against the abutment seat. By setting abutment seats of different lengths, it is possible to detect different degrees of shaking of the early warning device body and improve the detection range. The reset component drives the reset seat to move through the driving structure, and the reset seat pushes the swing rod to achieve the reset of the swing rod. The reset seat is movably installed on the detection box, with one end outside the detection box and the other end inside the detection box. The buffer device is used to increase the rigid collision between the reset seat and the swing rod, and at the same time, the stability of the swing rod during rotation is improved.

[0015] Furthermore, the driving structure includes:

[0016] A drive disc is installed on the early warning device body;

[0017] A driving device, used for driving the driving disc to rotate;

[0018] A mounting seat, used for mounting the driving device, wherein the mounting seat is movably connected to the warning device body;

[0019] a first spring, disposed between the mounting seat and the warning device body;

[0020] Among them, the driving disk is provided with a driving part, the driving part is connected to the driving device, the driving disk is provided with a pushing part corresponding to the reset seat, the early warning device body is provided with a pushing groove adapted to the pushing part, and the early warning device body is provided with a movable groove adapted to the mounting seat.

[0021] The axis of the driving disk is the same as the axis of the early warning device body. The driving disk is driven to rotate by the driving device, so that the pushing part on the driving disk pushes the reset seat to move. The pushing part is provided with several reset seats on the detection box. The pushing part extends from the driving disk to the early warning device body through the pushing groove. The driving device is installed on the mounting seat, and the mounting seat is installed in the movable groove. Under the action of the first spring, the mounting seat is abutted against one side of the movable groove. When the driving device drives the driving disk to rotate, the mounting seat does not move. When the driving disk is manually driven to rotate, the mounting seat moves in the movable groove. After the drive is completed, the driving disk is reset by the first spring. The driving part is used to be connected to the driving device.

[0022] Furthermore, the driving device adopts a motor, the driving part is provided with a tooth part, and the output shaft of the motor is provided with a gear adapted to the tooth part.

[0023] When the driving device is a motor, a gear is installed on the output shaft of the motor, and a tooth portion is provided on the driving portion. The tooth portion cooperates with the gear, and the driving disk rotates through the rotation of the gear. The tooth portion is strip-shaped.

[0024] Furthermore, the driving device adopts an electric cylinder, and the electric cylinder is hinged to the mounting seat and the driving part.

[0025] When the driving device is an electric cylinder, the electric cylinder drives the extension and retraction to rotate the driving disk.

[0026] Furthermore, the drive disc is provided with anti-slip protrusions on the outer side.

[0027] The anti-skid protrusions increase the friction of the drive disc during manual rotation, thereby further improving the stability of the manual rotation of the drive disc.

[0028] Furthermore, the buffer device includes:

[0029] A buffer chamber is installed on the reset seat;

[0030] A buffer seat is installed in the buffer cavity, and the buffer seat is provided with a first piston disposed in the buffer cavity;

[0031] A storage chamber is disposed on the early warning device body;

[0032] a second piston disposed in the storage chamber;

[0033] a third piston disposed in the storage chamber, wherein the third piston is provided with a push rod;

[0034] a third spring disposed between the second piston and the third piston;

[0035] A connecting pipe is placed between the buffer chamber and the storage chamber;

[0036] Wherein, the buffer chamber or the storage chamber contains a buffer solution.

[0037] When the reset seat pushes the swing arm to rotate, the buffer seat and the swing arm are counteracted, so that the first piston on the buffer seat moves in the buffer chamber, and the buffer solution in the buffer chamber flows to the storage chamber through the connecting pipe, thereby realizing the buffering performance of the buffer device, and the second piston moves in the storage chamber and compresses the third spring. When the reset seat is reset, the buffer solution is refilled in the buffer chamber through the third spring. When the driving disk is manually rotated, the mounting seat moves and the mounting seat is counteracted against the top rod. At this time, the second piston and the third piston are moved during the resetting process of the swing arm. Under the change of the buffer solution in the storage chamber and the action of the third spring, when the swing arm is manually reset, the second piston and the third piston move slowly to refill the buffer chamber and the mounting seat is slowly reset.

[0038] Furthermore, the buffer seat is Y-shaped, and is provided with an elastic membrane. A sealed cavity is formed between the elastic membrane and the edges of both ends of the buffer seat. The buffer seat is provided with a connecting hole, and the connecting hole connects the buffer cavity and the sealed cavity.

[0039] The elastic membrane increases the flexible contact between the buffer seat and the swing rod to prevent the swing rod from bending when it is reset. The buffer in the buffer seat is connected to the sealing cavity through the connecting hole, so that there is a buffer in the sealing cavity for buffering, and the elastic membrane is not easy to clamp the swing rod when it is deformed after being released from the swing rod, thereby preventing the swing rod from moving when the reset seat retreats.

[0040] This application also provides a method for using a landslide warning device, the specific steps of which include:

[0041] S1, automatic control, controls the driving device to rotate the driving disk, so that the pushing part pushes the reset seat to move toward the detection mechanism. When the buffer seat abuts against the swing rod, the driving device is continuously controlled to drive until the swing rod abuts against the abutting seat, and the driving device is controlled to rotate and reset the driving disk;

[0042] S3, manual control, manually push the drive disc to rotate, control the reset seat to rotate the swing rod, so that the swing rod is reset. After letting go, the drive disc slowly resets automatically.

[0043] By setting up two types of reset for the swing arm, automatic control and manual control, convenient, fast and diverse reset operations of the swing arm are achieved, thereby increasing the service life of the warning device body.

[0044] The beneficial effects of this application are:

[0045] 1. Reset all the swing rods through the reset assembly so that all the swing rods are against the abutment seat. The reset assembly drives the reset seat to move through the driving structure, and pushes the swing rod through the reset seat to achieve the reset of the swing rod.

[0046] 2. The buffer device is used to improve the rigid collision between the reset seat and the swing rod, and at the same time improve the stability of the swing rod during rotation, to prevent the vibration of the reset seat when retreating after the swing rod is reset, which may cause the detection mechanism to be re-triggered.

[0047] 3. The driving device drives the driving disk to rotate, so that the pushing part on the driving disk pushes the reset seat to move. The pushing part is provided with several reset seats on the detection box. When the driving device drives the driving disk to rotate, the mounting seat does not move. When the driving disk is manually driven to rotate, the mounting seat moves in the movable groove. After the drive is completed, the driving disk is reset by the first spring.

[0048] 4. When the reset seat pushes the swing rod to rotate, the buffer seat and the swing rod are abutted against each other, so that the first piston on the buffer seat moves in the buffer cavity, and the buffer in the buffer cavity flows into the storage cavity through the connecting pipe, thereby realizing the buffering performance of the buffer device.

[0059] The following provides a detailed description of the embodiments of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0060] Example 1:

[0061] like Figure 1 、 Figure 2 、 Figure 3 As shown, the embodiment of the present application provides an early warning device for landslide disasters, including an early warning device body 100 and several detection boxes 200 placed in the early warning device body 100. The detection boxes 200 include:

[0062] Magneto-induction module 210;

[0063] The communication module 220 is electrically connected to the magnetic induction module 210;

[0064] The detection mechanism 230 is installed in the detection box 200, and the detection mechanism 230 includes a rotating shaft 231, a rotating ring 232, a swing rod 233, and a permanent magnet block 234;

[0065] The abutment seat 240 is installed in the detection box 200. The abutment seat 240 is provided with a plurality of evenly arranged abutment seats 240, and the length thereof is gradually increased.

[0066] The reset assembly 300 is used to reset the swing rod 233 to abut against the abutment seat 240. The reset assembly 300 includes a driving structure 310, a reset seat 320, and a reset spring 330;

[0067] The buffer device 400 is placed on the reset seat 320 and is adapted to the swing rod 233;

[0068] The magnetic induction module 210 is placed on one side of the detection mechanism 230 , the abutment seat 240 is placed on the other side of the detection box 200 , and the reset spring 330 is placed between the reset seat 320 and the detection box 200 .

[0069] The magneto-induction module 210 and the communication module 220 are installed in the detection box 200. When the early warning device body 100 shakes or falls over, the detection mechanism 230 in the detection box 200 is affected, causing the swing rod 233 to rotate around the rotating shaft 231 through the rotating ring 232, and the permanent magnet acts on the magneto-induction module 210. The magneto-induction module 210 generates an electrical signal and transmits it to the communication module 220. However, when the early warning device body 100 is only subjected to severe shaking without a landslide disaster, the early warning signal of the detection box 200 can also be triggered, and the early warning device body 100 without a landslide disaster can still continue to be used, and all the swings are reset by the reset component 300. The movable rod 233 is reset, so that all the swing rods 233 are abutted against the abutment seat 240. By setting the abutment seats 240 of different lengths, it is possible to detect different degrees of shaking of the early warning device body 100, thereby improving the detection range. The reset component 300 drives the reset seat 320 to move through the driving structure 310, and the reset seat 320 pushes the swing rod 233 to achieve the reset of the swing rod 233. The reset seat 320 is movably installed on the detection box 200, with one end outside the detection box 200 and the other end inside the detection box 200. The buffer device 400 is used to increase the rigid collision between the reset seat 320 and the swing rod 233, and at the same time, the stability of the swing rod 233 during rotation is improved.

[0070] Furthermore, the driving disc 500 is provided with anti-slip protrusions 503 on the outer side.

[0071] The anti-skid protrusions 503 increase the friction of the driving disc 500 during manual rotation, thereby further improving the stability of the manual rotation of the driving disc 500.

[0072] Example 2:

[0073] like Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 As shown, the embodiment of the present application provides an early warning device for landslide disasters. In addition to the above technical features, the driving structure 310 further includes:

[0079] The axis of the driving disk 500 is the same as the axis of the early warning device body 100. The driving disk 500 is driven to rotate by the driving device 510, so that the pushing part 502 on the driving disk 500 pushes the reset seat 320 to move. The pushing part 502 is provided with several reset seats 320 on the detection box 200, which correspond one to one. The pushing part 502 extends from the driving disk 500 into the early warning device body 100 through the pushing groove 101. The driving device 510 is installed on the mounting seat 520, and the mounting seat 520 is installed in the movable groove 102. Under the action of the first spring 530, the mounting seat 520 is abutted against one side of the movable groove 102. When the driving device 510 drives the driving disk 500 to rotate, the mounting seat 520 does not move. When the driving disk 500 is manually driven to rotate, the mounting seat 520 moves in the movable groove 102. After the drive is completed, the driving disk 500 is reset by the first spring 530. The driving part 501 is used to be connected to the driving device 510.

The tooth portion 511 cooperates with the gear 512. The driving disk 500 rotates when the gear 512 rotates. The tooth portion 511 is strip-shaped.

[0083] Example 4:

[0084] like Figure 6 As shown, an embodiment of the present application provides an early warning device for landslide disasters. In addition to the above-mentioned technical features, the driving device 510 further adopts an electric cylinder, which is hinged to the mounting seat 520 and the driving part 501.

[0085] When the driving device 510 is an electric cylinder, the electric cylinder drives the extension and retraction to rotate the driving disk 500 .

[0086] Example 5:

[0087] like Figure 4 、 Figure 7 As shown, the embodiment of the present application provides an early warning device for landslide disasters. In addition to the above technical features, the buffer device 400 further includes:

[0088] The buffer chamber 410 is mounted on the reset seat 320;

[0095] The buffer chamber 410 or the storage chamber 430 contains a buffer solution.

[0096] When the reset seat 320 pushes the swing rod 233 to rotate, the buffer seat 420 is counteracted with the swing rod 233, so that the first piston 421 on the buffer seat 420 moves in the buffer chamber 410, and the buffer in the buffer chamber 410 flows to the storage chamber 430 through the connecting pipe 470, thereby realizing the buffering performance of the buffer device 400, and the second piston 440 moves in the storage chamber 430, compressing the third spring 460. When the reset seat 320 is reset, the buffer chamber 410 is refilled with buffer through the third spring 460. When the driving disk 500 is manually rotated, the mounting seat 520 moves and the mounting seat 520 is counteracted with the push rod 451. At this time, the second piston 440 and the third piston 450 are moved during the resetting process of the swing rod 233. Under the action of the change of the buffer in the storage chamber 430 and the third spring 460, when the swing rod 233 is manually reset, the second piston 440 and the third piston 450 move slowly, so that the buffer chamber 410 is refilled, and the mounting seat 520 is slowly reset.

[0099] The elastic membrane 422 increases the flexible contact between the buffer seat 420 and the swing rod 233 to prevent the swing rod 233 from bending when it is reset. The buffer in the buffer seat 420 is connected to the sealing cavity 423 through the connecting hole 424, so that there is a buffer in the sealing cavity 423 for buffering, and the elastic membrane 422 is not easy to clamp the swing rod 233 when it is deformed after being released from the swing rod 233, thereby preventing the swing rod 233 from moving when the reset seat 320 retreats.

[0102] S1, automatic control, controls the driving device 510 to rotate the driving disk 500, causing the pushing portion 502 to push the reset seat 320 toward the detection mechanism 230. After the buffer seat 420 abuts against the swing rod 233, the driving device 510 is continuously controlled to drive until the swing rod 233 abuts against the abutting seat 240. The driving device 510 is then controlled to rotate and reset the driving disk 500.

[0103] S3, manual control, manually push the driving disk 500 to rotate, control the reset seat 320 to rotate the swing rod 233, so that the swing rod 233 is reset, and after letting go, the driving disk 500 slowly and automatically resets.
