Description

Technical Field

[0001] This utility model belongs to the technical field of landslide monitoring devices, specifically relating to a geological landslide disaster monitoring device. Background Technology

[0002] Landslide disasters refer to the phenomenon in which a portion of rock and soil on a mountain slope moves downhill as a whole due to shear displacement along a certain weak structural plane under the action of gravity. The part of rock and soil that separates from the stable slope and slides after a landslide occurs is called the landslide body, and the stationary body above the landslide body is called the landslide wall.

[0003] Chinese patent CN222774898U discloses a simple landslide monitoring and early warning device. The device includes symmetrically arranged support rods, with several horizontal tubes fixedly connected between the two support rods. Each horizontal tube has an alarm component in its middle. The alarm component includes an alarm device fixedly connected inside the horizontal tube. The alarm device is fixedly connected to a steel wire rope. A steel plate is fixedly connected to the end of the steel wire rope away from the alarm device. The above device uses the steel plate to drive the steel wire rope to move, causing the steel wire rope to trigger the alarm device.

[0004] In the above scheme, the two ends of the wire rope are fixedly connected to the alarm and the steel plate, which are fixedly installed in the horizontal pipe, respectively. When the steel plate moves quickly with the landslide, the wire rope is prone to pulling damage to the alarm, and may even pull the support rod down with the landslide, resulting in a high cost of using the above scheme. Utility Model Content

[0005] The present invention aims to provide a geological landslide disaster monitoring device to reduce the cost of using landslide monitoring devices.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A landslide disaster monitoring device includes a fixed rod fixedly inserted into a landslide wall and a fixed base fixedly installed on the landslide body. A mounting box is rotatably mounted on the top of the fixed rod. The mounting box has an inner cavity, and an alarm module is fixedly mounted on the top of the mounting box. A rocker switch is mounted on the bottom of the alarm module. A magnetic block is fixedly mounted on the top of the bottom wall of the inner cavity, and a slider that can slide along the length of the mounting box is located within the inner cavity. The magnetic block and the slider are magnetically connected. The rocker switch is triggered during the slider's sliding motion. A pull rope slides through the side wall of the slider. A limiting structure for locking the pull rope is located inside the slider. An opening is formed on the inner side wall of the inner cavity away from the magnetic block, and a top rod for unlocking the limiting structure is fixedly mounted thereon. The pull rope passes through the opening. The top of the fixed base is connected to the pull rope. When the slider slides along the length of the mounting box, the top rod can press against and unlock the limiting structure. During unlocking, there is a gap between the slider and the inner side wall of the inner cavity with the opening.

[0008] The principle and effects of this technical solution:

[0009] In the initial state, the slider is magnetically connected to the magnetic block, and the pull rope is connected to the slider through a limiting structure. During installation, the fixing rod and fixing seat are respectively placed on the landslide wall and the landslide body, and the pull rope extends out of the mounting box and is connected to the fixing seat. When a landslide occurs, the fixing seat moves downward with the landslide body, and the pull rope drives the slider to slide along the length of the mounting box. During the sliding of the slider, the rocker switch is triggered, and the alarm module is activated. As the slider continues to move, the top rod releases the limiting structure from locking the pull rope. The pull rope first detaches from the slider, and then comes out of the mounting box through the opening, sliding down with the fixing seat and the landslide body.

[0010] With the above settings, the fixed base moves with the landslide body, causing the slider to move and triggering the alarm module to work. Then, before the slider contacts the inner wall of the mounting box, the locking structure of the pull rope is released, preventing the fixed rod, mounting box and alarm module from being pulled and damaged by large tension or sliding down with the landslide body, thus achieving the purpose of reducing the cost of use.

[0011] In this utility model, the slider sidewall has a through hole, the pull rope slides through the through hole, the inner sidewall of the through hole has a limiting groove, the inner sidewall of the limiting groove has a through insertion hole aligned with the top rod, the limiting structure includes a limiting block and a tension spring, the limiting block is slidably inserted into the limiting groove, the end of the limiting block near the through hole has a guide inclined surface that cooperates with the top rod, the end of the limiting block away from the through hole has a connecting rod that slides through the slider, the end of the connecting rod has a baffle fixedly installed, the tension spring is sleeved on the connecting rod, and the two ends of the tension spring are respectively connected to the outer sidewall of the slider and the baffle, and the end of the pull rope extending into the mounting box is fixedly connected to a movable block.

[0012] The principle and effects of this technical solution:

[0013] Before the landslide, the movable block is located in the through hole. The tension spring drives the end of the limiting block near the through hole to abut against the side wall of the pull rope. At this time, the end of the movable block connected to the pull rope abuts against the straight section of the limiting block. When the pull rope moves with the fixed base, it pulls the movable block to move. The movable block pushes the limiting block and the slider to move along the length of the mounting box. During the movement of the slider, the outer wall of the slider pushes the rocker switch to rotate, thereby activating the alarm module. Then, the slider continues to slide along the length of the mounting box below the rocker switch. At this time, the push rod is inserted into the limiting groove through the insertion hole relative to the slider. After the end of the push rod contacts the guide slope of the limiting block, it pushes the limiting block to move into the limiting groove. When the limiting block moves into the limiting groove, the movable block can move relative to the slider and pass through the through hole and the opening in sequence.

[0014] The above settings achieve the purpose of triggering the alarm module by pulling the slider with the pull rope, while also allowing the pull rope to be disconnected from the slider before it comes into contact with the inner wall of the mounting box.

[0015] This utility model also includes a telescopic rod, which includes a rod sleeve and a movable rod. One end of the rod sleeve is threaded to the outer wall of the mounting box, and the rod sleeve is coaxially arranged with the opening. One end of the movable rod is slidably inserted into the other end of the rod sleeve, and the other end of the movable rod is rotatably connected to the fixed seat. The pull rope is threaded through the rod sleeve and connected to the movable rod.

[0016] In this utility model, the movable rod is provided with a through receiving groove along its axial direction, and a through screw hole is provided on the inner side wall of the receiving groove. A bolt is inserted into the screw hole by thread, and the pull rope slides through the receiving groove.

[0017] By using the above settings, the rope is covered by a telescopic rod to prevent it from being pulled by wild animals and accidentally triggering the alarm module.

[0018] In this invention, slide rails are fixedly provided at intervals on the top of the inner wall of the cavity, and slide grooves are provided on both side walls of the slider. The two slide rails are slidably embedded in the corresponding slide grooves. Through the above arrangement, the movement direction of the slider can be restricted.

[0019] In this invention, a fixing plate is fixedly mounted on the top of the fixing rod, and support plates are fixedly mounted on both ends of the top of the fixing plate. Connecting blocks that are rotatably inserted into adjacent support plates are fixedly mounted on both side walls of the mounting box. Through the above arrangement, the mounting box can be rotatably mounted on the top of the fixing rod.

[0020] In this invention, a rod is fixedly installed at the bottom of the fixing base. This design allows the fixing base to be installed on the landslide body, ensuring that the fixing base moves with the landslide body and improving the accuracy and timeliness of the landslide monitoring results.

[0031] In this embodiment, the slider 50 has a through hole 51 on its side wall, and the pull rope 60 slides through the through hole 51. The inner side wall of the through hole 51 is provided with a limiting groove 52.

The end of the limiting block 71 near the through hole 51 is provided with a guide slope that cooperates with the top rod 34. The end of the limiting block 71 away from the through hole 51 is fixedly provided with a connecting rod 711 that slides through the slider 50. The end of the connecting rod 711 is fixedly provided with a baffle 712. The tension spring 72 is sleeved on the connecting rod 711, and the two ends of the tension spring 72 are respectively connected to the outer side wall of the slider 50 and the baffle 712. The end of the pull rope 60 that extends into the mounting box 30 is fixedly connected to a movable block 61. The inner diameter of the opening 33 is larger than the inner diameter of the through hole 51.

[0032] In this embodiment, a telescopic rod 80 is also included. The telescopic rod 80 includes a rod sleeve 81 and a movable rod 82. One end of the rod sleeve 81 is threaded to the outer wall of the mounting box 30, and the rod sleeve 81 is coaxially arranged with the opening 33. One end of the movable rod 82 is slidably inserted into the other end of the rod sleeve 81, and the other end of the movable rod 82 is rotatably connected to the fixed seat 20. The pull rope 60 passes through the rod sleeve 81 and is connected to the movable rod 82.

[0033] In this embodiment, the movable rod 82 is provided with a through receiving groove 821 along its axial direction, and a through screw hole 822 is provided on the inner side wall of the receiving groove 821. A bolt 83 is threaded into the screw hole 822, and the pull rope 60 slides through the receiving groove 821.

[0034] In this embodiment, the top of the inner bottom wall of the inner cavity 31 is fixedly provided with slide rails 35 at intervals, and the two side walls of the slider 50 are provided with slide grooves 54, and the two slide rails 35 are slidably embedded in the corresponding slide grooves 54.

[0035] In this embodiment, a fixing plate 11 is fixedly installed on the top of the fixing rod 10, and support plates 12 are fixedly installed at both ends of the top of the fixing plate 11. Connecting blocks 36 that are rotatably inserted into the adjacent support plates 12 are fixedly installed on both sides of the mounting box 30.

[0036] In this embodiment, a chisel 21 is fixedly provided at the bottom of the fixing base 20.

[0037] The specific implementation process is as follows:

[0038] In the initial state, the slider 50 is magnetically connected to the magnetic block 32, and the pull rope 60 is connected to the slider 50 through the limiting structure. During installation, the fixing rod 10 and the fixing seat 20 are respectively set on the landslide wall 1 and the landslide body 2, and the pull rope 60 extends one end out of the mounting box 30 and is connected to the fixing seat 20. When the landslide occurs, the fixing seat 20 moves downward with the landslide body 2, and the pull rope 60 drives the slider 50 to slide along the length direction of the mounting box 30. During the sliding of the slider 50, the rocker switch 41 is triggered, so that the alarm module 40 works. As the slider 50 continues to move, the top rod 34 releases the locking of the limiting structure on the pull rope 60. The pull rope 60 first separates from the slider 50, and then comes out of the mounting box 30 through the opening 33, and slides down with the fixing seat 20 and the landslide body 2.

[0039] Before the landslide, the movable block 61 is located inside the through hole 51. The tension spring 72 drives the end of the limiting block 71 near the through hole 51 to abut against the side wall of the pull rope 60. At this time, the end of the movable block 61 connected to the pull rope 60 abuts against the straight section of the limiting block 71. When the pull rope 60 moves with the fixed base 20, it pulls the movable block 61 to move. The movable block 61 pushes the limiting block 71 and the slider 50 to move along the length of the mounting box 30. During the movement of the slider 50, the outer wall of the slider 50 pushes the rocker switch 41 to rotate. The movement activates the alarm module 40. Subsequently, the slider 50 continues to slide along the length of the mounting box 30 below the rocker switch 41. At this time, the push rod 34 is inserted into the limiting groove 52 through the insertion hole 53 relative to the slider 50. After the end of the push rod 34 contacts the guide slope of the limiting block 71, it pushes the limiting block 71 to move into the limiting groove 52. When the limiting block 71 moves into the limiting groove 52, the movable block 61 can move relative to the slider 50 and pass through the through hole 51 and the opening 33 in sequence.
