Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of geological disaster early warning, and specifically relates to a geological disaster early warning monitoring device. BACKGROUND

[0002] Geological disasters are caused by disastrous damage of natural and human geological actions to geological environment, and mainly include collapse, landslide, debris flow, ground subsidence and ground fissure; China is one of the regions with frequent geological disasters in the world, and in recent years, the research on landslide and debris flow disasters along railways is one of the focuses of the industry. In order to reduce the loss of life and property along the railway caused by geological disasters, regional risk prediction is usually carried out, and a monitoring and early warning device can be used for monitoring before the occurrence of geological disasters, so as to achieve the purpose of early warning of train operation along the railway, timely evacuation of people and protection of the safety of people's life and property.

[0003] For example, patent number CN114673875A discloses a geological disaster early warning monitoring device, which belongs to the field of geological disaster early warning. The geological disaster early warning monitoring device comprises two groups of fixed columns, a landslide extensometer and a pull rope. The landslide extensometer is fixedly connected to the two groups of fixed columns. The pull rope is connected to the landslide extensometers on the two groups of fixed columns at both ends. The device further comprises a fixed box fixedly connected to the two groups of fixed columns. The fixed box is rotatably connected to a first screw rod. The first screw rod is threadedly connected to a push rod mechanism. The push rod mechanism is provided with a limiting plate abutting against the pit wall. The fixed column is slidably connected to a steel wire rope. The push rod mechanism drives the limiting plate to move, so that the limiting plate always maintains the state of abutting against the inner wall of the pit groove to fix the fixed column, improves the stability of the fixed column, reduces the interference of shaking on the landslide extensometer, and improves the accuracy and stability of early warning and monitoring.

[0004] During the use of the device, it is found that the technology has the following problems. The device uses the length value of the pull rope on the landslide extensometer assembly to determine the danger degree of landslide. However, in the snow season with a long duration, a large amount of ice and snow will adhere to the pull rope, thereby causing a certain downward pressure on the pull rope. At this time, the weight of the adhered ice and snow cannot be reduced in a short time, and thus the pull rope may continuously pull the pull line, causing the control of the wire reel to reach the warning length, thereby causing misjudgment. Therefore, in order to solve the problem, it is necessary to provide a geological disaster early warning monitoring device. CONTENT OF THE INVENTION

[0007] A swinging device is fixedly installed on the inner side of the top of the detection rod, a special-shaped rod is rotatably installed in the swinging device, a sleeve rod is sleeved and installed on the middle of the special-shaped rod, a connecting rod is hingedly installed on the bottom of the sleeve rod, a limiting hole for the up-and-down movement of the connecting rod is formed in the bottom of the swinging device, a sleeve is fixedly installed on the bottom of the connecting rod, a pull rope is insertedly installed on the middle of the sleeve, a second spring is fixedly installed on the outer end of the pull rope, and the inner end of the second spring is fixedly connected to the outer wall of the sleeve.

[0008] In a preferred embodiment, the number of the lock floors is two, and the two lock floors are respectively installed on the two sides of the cracks at landslide-prone locations, and the bottom of the lock floor is fixed on the detection position base surface through concrete pouring.

[0009] In a preferred embodiment, a limiting sliding groove matching the rack is formed in the bottom of the track plate, and the rack is slidably installed in the limiting sliding groove.

[0010] In a preferred embodiment, nitrogen cylinders whose inner ends extend into the track plate are fixedly installed on both ends of the track plate, a piston is slidably installed in the nitrogen cylinder, and a push-pull rod which is inserted into the nitrogen cylinder and is fixed to the piston is fixedly installed on both ends of the rack.

[0011] In a preferred embodiment, a first spring is fixedly installed on the outer periphery of the push-pull rod at both ends of the rack, the outer end of the first spring is fixedly connected to the wall of the track plate, and the chamber on the outer side of the piston in the nitrogen cylinder is filled with nitrogen.

[0012] In a preferred embodiment, the special-shaped rod is of a U-shaped structure, a driving motor whose output shaft is fixed to the special-shaped rod is fixedly installed in the swinging device, the inner end of the special-shaped rod is fixedly connected to the inner wall of the swinging device through a bearing, and the air temperature detector and the landslide extensometer are electrically connected to a circuit control panel for controlling the opening and closing of the driving motor.

[0013] In summary, due to the adoption of the above technical scheme, the present application has the following beneficial effects:

[0014] 1、In this application, through the above design, when the inner side of the detection rod is subjected to tension, the detection rod will rotate around the bottom end of the shaft, and a certain angle will be generated on the corner base. At this time, when the corner base rotates, the gears on both sides of the corner base will mesh with the rack to move linearly. At this time, one of the two springs on both sides of the rack is compressed and the other is tensioned, thereby generating a certain resistance to the movement of the rack. At the same time, the push-pull rods at both ends of the rack are squeezed to drive the piston in the nitrogen cylinder to move, so that one of the nitrogen chambers in the two nitrogen cylinders is in a positive pressure state and the other is in a negative pressure state, thereby further generating resistance to the movement of the rack. At the same time, it has a certain buffering capacity, so as to ensure that when the detection rod is subjected to tension from the inner side, the corner force will be transmitted to the spring and the nitrogen chamber in the nitrogen cylinder to reduce the force, so as to prevent the detection rod from directly transmitting the force to the locking plate to cause shaking, so that the base fixing pit surface of the locking plate becomes larger, and the locking plate loses its fixation. At the same time, when the inner side of the detection rod loses tension, the detection rod will also return to its original position and maintain its original posture.

[0015] 2、In this application, based on the description in the above paragraph, when the pull rope is attached with ice and snow in winter, the detection rods at the two measurement locations will be subjected to force and inclined inward under the action of the tension of the pull rope. At this time, the wire control end on the landslide extensometer will be dragged a distance by the inclined detection rod through the connecting rope and be sensed. At this time, the temperature detector is at a temperature in the local winter. When both are sensed at the same time, the detection rod is inclined under the winter temperature, so that the temperature detector and the landslide extensometer will send an electrical signal to the circuit control board that controls the starting of the driving motor to control the starting of the driving motor to drive the special-shaped rod to rotate. The rotation of the special-shaped rod drives the connecting rod to move up and down reciprocally through the sleeve rod. At this time, the connecting rod drives the pull rope to swing up and down through the sleeve, and the ice and snow attached to the pull rope is shaken off, thereby reducing the weight of the pull rope and allowing the detection rod to recover to its original state without being subjected to tension from the inner side. At this time, the landslide extensometer does not issue a warning. However, when the detection rod does not return to its original position, or when the detection rod is subjected to tension from the inner side and is inclined while the temperature detector does not detect that the temperature is in the cold season of winter, it indicates that the two locking plates located on both sides of the landslide crack are likely to move away from each other. At this time, the landslide extensometer issues a warning, indicating that the landslide is likely to have occurred or is occurring, thereby achieving the effect of detection and warning to alert the trains and people along the railway to move away.

[0023] When the inner side of the detection rod 4 is subjected to a pulling force, the detection rod 4 will rotate around the bottom end of the rotating shaft 3, and a certain angle will be generated on the rotating angle base 2. At this time, when the rotating angle base 2 rotates, the gears 11 on both sides of the rotating angle base 2 will mesh with the rack 10 to move linearly. At this time, one of the two springs 15 on both sides of the rack 10 is compressed, and the other is pulled, thereby generating a certain resistance to the movement of the rack 10.

When both are sensed at the same time, i.e. the detection rods 4 are tilted at the winter temperature, the temperature detector 8 and the landslide extensometer 6 will send an electrical signal to the circuit control board to control the driving motor 18 to start, so as to drive the special-shaped rod 17 to rotate, and the rotation of the special-shaped rod 17 will drive the connecting rod 20 to move up and down reciprocatingly through the sleeve rod 19, at this time, the connecting rod 20 will drive the pull rope 22 to swing up and down through the sleeve block 21, so as to shake off the ice and snow attached to the pull rope 22, thereby reducing the weight of the pull rope 22, and the detection rods 4 are restored to the original state without the inward pulling force.
