Description

Technical Field

[0001] This invention belongs to the technical field of disaster monitoring and alarm equipment, specifically relating to a landslide disaster monitoring device. Background Technology

[0002] Landslides refer to the rapid sliding of large amounts of soil and rock material along a mountainside due to factors such as gravity, rainfall, and earthquakes. Their hazards primarily include damage to housing, infrastructure, and farmland, potentially causing serious casualties and property losses. Especially during highway tunnel construction, a series of geological disasters are unavoidable, including sudden water and mudflows, rock bursts, large deformations, tunnel entrance landslides, and rock collapses. These factors greatly complicate tunnel surveying, design, and construction, severely hindering safe and efficient tunnel construction. Therefore, improving the stability control of tunnel entrance slopes is crucial, requiring effective and safe responses through the prediction and prevention of tunnel entrance slope disasters.

[0003] Chinese Patent Application No. 202410619168.4 discloses a distributed landslide monitoring and early warning device and system. This integrated monitoring device and system comprehensively monitors surface displacement, deep displacement, rainfall, and groundwater levels of the mountain, and uses monitoring floats to conduct subsequent monitoring of landslide disasters. The distributed monitoring network effectively improves the accuracy of assessing mountain instability risks and provides timely early warnings of landslides. It consists of a displacement monitoring structure, a rainfall monitoring structure, and a post-disaster monitoring structure. The displacement monitoring structure comprises a hollow support column, a deep displacement monitoring tube, a fixing plate, a fixing groove, a surface displacement monitoring tube, a flexible connecting pipe, and a power supply. One end of the deep displacement monitoring tube is placed at one end of the hollow support column, and the power supply is placed inside the hollow support column. The other end of the hollow support column is an open structure, and the deep displacement monitoring tube contains a deep displacement sensor.

[0004] When installing landslide monitoring equipment, since the equipment generally has sensors, if some equipment with the function of detecting different depths is installed, the surrounding soil may damage the sensors during the installation process due to the deep installation location, making the installation inconvenient. Some equipment is also difficult to remove after installation, leading to difficulties in later maintenance. At the same time, how to ensure the installation stability of the monitoring equipment is also one of the research directions. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a landslide disaster monitoring device. This invention not only protects the pressure sensor from damage during installation and removal but also makes the monitoring device more securely installed. This invention not only limits and fixes the pressure sensor but also further improves the installation stability of the monitoring device. This invention not only makes the installation pipe easier to lower and install but also enables rapid disassembly.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A landslide disaster monitoring device includes an installation tube with a positioning rod slidably connected inside it. A monitoring box is fixedly installed at the upper end of the positioning rod. Multiple monitoring holes are evenly spaced vertically on the installation tube, and multiple pressure sensors are correspondingly fixedly connected to the positioning rod. An electrical cable channel is provided inside the positioning rod. A power supply, a control module, and a Wi-Fi module are installed inside the monitoring box. An audible and visual alarm is fixedly installed on the top of the monitoring box. The Wi-Fi module and the audible and visual alarm are electrically connected to the control module, which is electrically connected to the power supply. The pressure sensors are electrically connected to the control module inside the monitoring box via wiring in the electrical cable channel. A sliding groove is vertically fixed on the inner wall of the installation tube, and the monitoring holes are located within the sliding groove. The outer shell of the pressure sensor is slidably connected to the sliding groove. Multiple protective mechanisms are also installed within the sliding groove to protect the pressure sensors during installation and removal of the monitoring device.

[0008] Furthermore, the upper end of the mounting tube is fixedly connected to an upper sliding sleeve by multiple first support rods, the upper sliding sleeve is fitted onto the positioning rod and slidably connected to the positioning rod; the lower end of the mounting tube is fixedly connected to a lower sliding sleeve by multiple second support rods, the lower sliding sleeve is fitted onto the positioning rod and slidably connected to the positioning rod.

[0009] A first mounting ring is fixedly provided on the upper periphery of the mounting tube, and a second mounting ring is fixedly provided on the positioning rod, with the second mounting ring located above the first mounting ring.

[0010] Furthermore, the lower end of the mounting tube is fixedly connected to a conical cylinder, the tip of the conical cylinder is provided with a through hole, and the lower end of the positioning rod is fixedly provided with a positioning cone, which passes through the through hole of the conical cylinder and faces outward.

[0011] Furthermore, the protective mechanism includes a protective plate, both ends of which are slidably connected to a sliding groove; a first limiting plate is fixedly provided at the upper end of the protective plate, the first limiting plate movably abutting against the bottom of the housing of the pressure sensor, and sliding rods are fixedly provided on both sides of the bottom of the first limiting plate; a plurality of stops are evenly fixedly provided on the sliding groove, each stop being located below a corresponding monitoring hole; two sliding holes are formed through the stops, and the sliding rods pass through the corresponding sliding holes and are slidably connected to the sliding holes; a second limiting plate is fixedly connected to the ends of the two sliding rods away from the first limiting plate; a limiting spring is sleeved on the sliding rod, and both ends of the limiting spring are fixedly connected to the first limiting plate and the stops, respectively.

[0012] Furthermore, when the second limiting plate abuts against the upper stop, the protective plate seals the monitoring hole.

[0013] Furthermore, a limiting mechanism is fixedly provided on the top of the housing of the pressure sensor. The limiting mechanism includes a sliding groove, which is fixedly connected to the top of the housing of the pressure sensor. A limiting block is slidably connected on the sliding groove. The limiting block has an inclined surface at one end away from the positioning rod, and the end of the inclined surface movably abuts against the inner wall of the mounting tube. A sliding hole is provided through the inside of the limiting block, and a second sliding rod is slidably connected on the sliding hole. One end of the second sliding rod is fixedly connected to the positioning rod. A return spring is sleeved on the second sliding rod, and both ends of the return spring are fixedly connected to the positioning rod and the limiting block, respectively.

[0014] Furthermore, when the positioning rod moves down, causing the end of the inclined plane to release its contact with the inner wall of the mounting tube, the inclined plane extends out of the monitoring hole, the flat end of the top of the limit block abuts against the monitoring hole, and the force detection end of the pressure sensor aligns with the corresponding monitoring hole.

[0015] Furthermore, the positioning rod is characterized by having an auxiliary mechanism installed on it, the auxiliary mechanism including a limiting ring and a second return spring, the limiting ring being located above the sliding sleeve and fixed to the positioning rod; the second return spring being sleeved on the positioning rod, and the two ends of the second return spring being fixedly connected to the limiting ring and the sliding sleeve respectively.

[0016] Furthermore, mounting ears are symmetrically fixed to the upper periphery of the positioning rod, and the mounting ears are fixedly connected to the bottom of the monitoring box by bolts; the monitoring box includes a monitoring box body and a door hinged to one side of the monitoring box body.

[0017] This invention also claims a method for monitoring landslide disasters using the aforementioned monitoring equipment, comprising the following steps:

[0018] S1. By pressing down the first mounting ring, the mounting tube is inserted into the soil. At this time, under the limit of the stop block, the positioning rod follows the mounting tube into the soil. During this process, the stop block always abuts against the second limiting plate below, and the protective plate seals the monitoring hole to protect the pressure sensor inside the mounting tube.

[0019] S2. If the installation pipe encounters an obstacle and cannot move down during the process of moving down, the second installation ring is controlled. Under the reset action of the second reset spring of the auxiliary mechanism, the positioning rod moves up and down repeatedly. At this time, the positioning cone continuously inserts into the soil below the cone cylinder, making it easier for the installation pipe to move down.

[0020] S3. After reaching the specified depth, the positioning rod continues to move downward by pressing down the second mounting ring. The positioning cone is inserted into the deeper soil for positioning until the inclined end of the limiting mechanism releases from contact with the inner wall of the mounting tube. The inclined surface extends out of the monitoring hole, and the flat end of the top of the limiting block abuts against the monitoring hole. At this time, the limiting mechanism and the limiting spring together limit the housing of the pressure sensor, so that the pressure sensor is aligned with the monitoring hole to monitor the soil.

[0021] S4. When it is necessary to disassemble the monitoring equipment, first pull the first and second mounting rings upwards. Through the reaction force of the surrounding soil on the inclined surface of the limiting mechanism, the limiting block extends into the monitoring hole. The flat end of the top of the limiting block releases from contact with the monitoring hole. At this time, under the reset action of the second return spring and the limiting spring, pull the second mounting ring upwards to move the positioning cone of the positioning rod upwards to release the positioning. At the same time, the protective plate moves upwards to close the monitoring hole and protect the pressure sensor. Then, by continuing to pull the second mounting ring upwards, under the limitation of the stop block on the second limiting plate, the positioning rod and the mounting tube move upwards together to achieve disassembly.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) This invention, through the cooperation of the positioning rod and the protective mechanism, not only protects the pressure sensor from damage during the loading and unloading of the monitoring equipment, but also makes the monitoring equipment more secure. Specifically, when the monitoring equipment needs to be installed, the first mounting ring is pressed down to insert the mounting tube into the soil. At this time, under the limit of the stop block, the positioning rod follows the mounting tube into the soil. During this process, the stop block always abuts against the second limiting plate below, and the protective plate seals the monitoring hole to protect the pressure sensor inside the mounting tube, thereby preventing the pressure sensor from being damaged by the surrounding soil during the downward movement. When the monitoring equipment needs to be disassembled, the second mounting ring is pulled up. Under the limit of the stop block by the second limiting plate, the protective plate seals the monitoring hole to protect the pressure sensor, thereby preventing the pressure sensor from being damaged by the surrounding soil during the upward movement. At the same time, after the installation reaches the specified depth, the positioning rod continues to move downward by pressing down the second mounting ring. The pressure sensor aligns with the monitoring hole to monitor the soil. At this time, the positioning cone is inserted deeper into the soil for positioning, making the monitoring equipment more secure.

[0024] (2) Through the cooperation of the limiting mechanism and the protective mechanism, this invention can not only limit and fix the pressure sensor to ensure that the force detection end of the pressure sensor is aligned with the corresponding monitoring hole, but also further improve the installation stability of the monitoring equipment. Specifically, when the second mounting ring is pressed down to release the inclined end of the limiting mechanism from the inner wall of the mounting tube, the inclined end extends out of the monitoring hole, and the flat end of the top of the limiting block abuts against the monitoring hole. At this time, the limiting mechanism and the limiting spring together limit the housing of the pressure sensor, so that the pressure sensor is aligned with the monitoring hole to monitor the soil. At this time, the end of the limiting block is inserted into the soil to fix the monitoring equipment laterally, which further improves the installation stability of the monitoring equipment.

[0025] (3) Through the cooperation of the auxiliary mechanism and the protective mechanism, this invention not only makes it easier to lower and install the installation pipe, but also enables quick disassembly. Specifically, when the installation pipe encounters an obstacle and cannot move down during the downward movement, the second installation ring is controlled, and under the reset action of the second reset spring of the auxiliary mechanism, the positioning rod moves up and down repeatedly. At this time, the positioning cone continuously inserts into the soil below the cone cylinder, making it easier for the installation pipe to move down. At the same time, when it is necessary to disassemble the monitoring equipment, the first installation ring and the second installation ring are pulled upward first. Through the reaction action of the surrounding soil on the inclined surface of the limiting mechanism, the limiting block extends into the monitoring hole, and the flat end of the top of the limiting block is released from contact with the monitoring hole. At this time, under the reset action of the second reset spring and the limiting spring, the positioning cone of the positioning rod can be quickly moved upward to release the positioning by pulling the second installation ring upward, thereby achieving quick disassembly.

[0037] Although the steps in this invention are arranged by reference numerals, this is not intended to limit the order of the steps. Unless the order of the steps is explicitly stated or the execution of a step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" as used herein refers to and covers any and all possible combinations of one or more of the associated listed items.

[0038] Example

[0039] like Figures 1 to 8As shown, a landslide disaster monitoring device includes an installation pipe 100, a positioning rod 300 slidably connected inside the installation pipe 100, and a monitoring box 200 fixedly installed at the upper end of the positioning rod 300; the installation pipe 100 has a plurality of monitoring holes 120 evenly spaced vertically, and a plurality of pressure sensors 500 are fixedly connected to the positioning rod 300 accordingly; the positioning rod 300 has an electrical cable channel 340 inside, the monitoring box 200 has a power supply, a control module, and a Wi-Fi module installed inside, and an audible and visual alarm 220 is fixedly installed on the top of the monitoring box 200; The Wi-Fi module and the audible and visual alarm 220 are both electrically connected to the control module, which is electrically connected to the power supply. The pressure sensor 500 is electrically connected to the control module in the monitoring box 200 via wiring in the wire trough 340. A sliding groove 800 is vertically fixed on the inner wall of the mounting tube 100, and the monitoring hole 120 is located in the sliding groove 800. The outer shell of the pressure sensor 500 is slidably connected to the sliding groove 800. Multiple protective mechanisms 400 are also installed in the sliding groove 800 to protect the pressure sensor 500 when the monitoring equipment is installed or removed.

[0040] The present invention, through the cooperation of the positioning rod 300 and the protective mechanism 400, not only protects the pressure sensor 500 from damage during the installation and removal of the monitoring equipment, but also makes the monitoring equipment more securely installed; details will be described in detail later.

[0041] It is worth noting that this invention utilizes multiple pressure sensors 500 to monitor the pressure within soil at different depths in corresponding monitoring holes 120, thereby determining the pressure changes within the soil at different depths and thus monitoring landslide hazards. When the pressure sensors 500 detect pressure changes within the soil at different depths, the information is transmitted to the control module, which then controls the audible and visual alarm 220 to trigger an alarm, alerting on-site personnel. Simultaneously, the control module uses a Wi-Fi module to transmit data and process alarms with nearby wireless network receiving devices or mobile communication service devices, thereby achieving rapid monitoring and early warning. Components such as the pressure sensors 500 and the control module can specifically employ piezoelectric pressure sensors, PLC control systems, etc., which will not be described in detail here.

[0042] Furthermore, the upper end of the mounting tube 100 is fixedly connected to an upper sliding sleeve 141 by a plurality of first support rods 140, and the upper sliding sleeve 141 is sleeved on the positioning rod 300 and slidably connected to the positioning rod 300; the lower end of the mounting tube 100 is fixedly connected to a lower sliding sleeve 151 by a plurality of second support rods 150, and the lower sliding sleeve 151 is sleeved on the positioning rod 300 and slidably connected to the positioning rod 300.

[0043] A first mounting ring 130 is fixedly provided on the upper periphery of the mounting tube 100, and a second mounting ring 320 is fixedly provided on the positioning rod 300, with the second mounting ring 320 located above the first mounting ring 130. The second mounting ring 320 is not only used for installation, but also allows for rain protection of the mounting tube 100.

[0044] It is worth noting that the first mounting ring 130 and the second mounting ring 320 of the present invention can be controlled manually or by mechanical force, which facilitates the installation of the monitoring equipment. The specific installation method will be described in detail later.

[0045] Furthermore, the lower end of the mounting tube 100 is fixedly connected to a conical cylinder 110, the tip of the conical cylinder 110 is provided with a through hole, and the lower end of the positioning rod 300 is fixedly provided with a positioning cone 310, which is arranged outward through the through hole of the conical cylinder 110.

[0046] It is worth noting that the design of the conical cylinder 110 and the positioning cone 310 facilitates the insertion of the monitoring equipment into the soil for installation. The purpose of not sealing the upper end of the installation pipe 100 is to facilitate the viewing of the internal condition of the installation pipe 100. At the same time, if a landslide occurs, the stability of the installation pipe 100 can be improved to a certain extent when soil enters the interior of the installation pipe 100.

[0047] Further, the protective mechanism 400 includes a protective plate 410, both ends of which are slidably connected to the sliding groove 800; a first limiting plate 411 is fixedly provided at the upper end of the protective plate 410, the first limiting plate 411 movably abuts against the bottom of the housing of the pressure sensor 500, and sliding rods 420 are fixedly provided on both sides of the bottom of the first limiting plate 411; a plurality of stops 810 are evenly fixedly provided on the sliding groove 800, each stop 810 being located below the corresponding monitoring hole 120; two sliding holes 811 are opened through the stop 810, and the sliding rods 420 pass through the corresponding sliding holes 811 and are slidably connected to the sliding holes 811; a second limiting plate 440 is fixedly connected to the ends of the two sliding rods 420 away from the first limiting plate 411; a limiting spring 430 is sleeved on the sliding rod 420, and both ends of the limiting spring 430 are fixedly connected to the first limiting plate 411 and the stop 810 respectively.

[0048] Furthermore, when the second limiting plate 440 abuts against the upper stop 810, the protective plate 410 seals the monitoring hole 120.

[0049] When the monitoring equipment needs to be installed, the first mounting ring 130 is pressed down to insert the mounting tube 100 into the soil. At this time, under the limitation of the stop block 810, the positioning rod 300 follows the mounting tube 100 into the soil. During this process, the stop block 810 always abuts against the lower second limiting plate 440, and the protective plate 410 seals the monitoring hole 120, protecting the pressure sensor 500 inside the mounting tube 100, thereby preventing the pressure sensor 500 from being damaged by collision with the surrounding soil during the downward movement. When the monitoring equipment needs to be disassembled, the second mounting ring 32 is pulled upward. 0. With the second limiting plate 440 limiting the stop block 810, the protective plate 410 always seals the monitoring hole 120 to protect the pressure sensor 500, thereby preventing the pressure sensor 500 from being damaged by the surrounding soil during the upward movement; at the same time, after the installation of the monitoring equipment reaches the specified depth, the positioning rod 300 continues to move downward by pressing down the second mounting ring 320, and the pressure sensor 500 is aligned with the monitoring hole 120 to monitor the soil. At this time, the positioning cone 310 is inserted into the deeper soil for positioning, making the installation of the monitoring equipment more secure.

[0050] It is worth noting that the pressure sensor 500 of the present invention can be equipped with a rigid outer shell, which is a conventional setting and therefore will not be described in detail. Since the force detection end 510 of the pressure sensor 500 is relatively sensitive, it is easily damaged by the soil when moving, so it needs to be protected. The external shape of the pressure sensor 500 can be designed according to the actual size and is a conventional adjustment.

[0051] Furthermore, a limiting mechanism 600 is fixedly provided on the top of the housing of the pressure sensor 500. The limiting mechanism 600 includes a sliding groove 650, which is fixedly connected to the top of the housing of the pressure sensor 500. A limiting block 610 is slidably connected on the sliding groove 650. The end of the limiting block 610 away from the positioning rod 300 is provided with an inclined surface 611, and the end of the inclined surface 611 is movably abutting against the inner wall of the mounting tube 100. A sliding hole 620 is provided through the interior of the limiting block 610. A second sliding rod 630 is slidably connected on the sliding hole 620. One end of the second sliding rod 630 is fixedly connected to the positioning rod 300. A return spring 640 is sleeved on the second sliding rod 630. The two ends of the return spring 640 are fixedly connected to the positioning rod 300 and the limiting block 610, respectively.

[0052] Furthermore, when the positioning rod 300 moves down, causing the end of the inclined surface 611 to release from contact with the inner wall of the mounting tube 100, the inclined surface 611 extends out of the monitoring hole 120, the flat end of the top of the limiting block 610 abuts against the monitoring hole 120, and the force detection end 510 of the pressure sensor 500 is aligned with the corresponding monitoring hole 120.

[0053] This invention, through the cooperation of the limiting mechanism 600 and the protective mechanism 400, not only limits and fixes the pressure sensor 500, ensuring that the force-detecting end 510 of the pressure sensor 500 is aligned with the corresponding monitoring hole 120, but also further improves the installation stability of the monitoring equipment. Specifically, when the second mounting ring 320 is pressed down to release the end of the inclined surface 611 of the limiting mechanism 600 from contact with the inner wall of the mounting tube 100, the inclined surface 611 extends out of the monitoring hole 120, and the flat end of the top of the limiting block 610 abuts against the monitoring hole 120. At this time, the limiting mechanism 600 and the limiting spring 430 together limit the housing of the pressure sensor 500, realizing that the pressure sensor 500 is aligned with the monitoring hole 120 to monitor the soil. At this time, the end of the limiting block 610 is inserted into the soil, fixing the monitoring equipment laterally, further improving the installation stability of the monitoring equipment.

[0054] It is worth noting that when the flat end of the top of the limiting block 610 abuts against the monitoring hole 120, since the flat end of the top of the limiting block 610 will not slide up and down with the monitoring hole 120, the second mounting ring 320 can be pulled up. If the positioning rod 300 cannot move up, it means that the flat end of the top of the limiting block 610 has abutted against the monitoring hole 120, so as to quickly determine whether the pressure sensor 500 is installed in place.

[0055] Furthermore, an auxiliary mechanism 700 is also installed on the positioning rod 300. The auxiliary mechanism 700 includes a limiting ring 710 and a second return spring 720. The limiting ring 710 is located above the sliding sleeve 151 and is fixed on the positioning rod 300. The second return spring 720 is sleeved on the mounting positioning rod 300, and its two ends are fixedly connected to the limiting ring 710 and the sliding sleeve 151, respectively.

[0056] This invention, through the cooperation of the auxiliary mechanism 700 and the protective mechanism 400, not only makes it easier to lower and install the mounting pipe 100, but also enables rapid disassembly. Specifically, when the mounting pipe 100 encounters an obstacle during its downward movement and cannot move further, the second mounting ring 320 is controlled, and under the reset action of the second return spring 720 of the auxiliary mechanism 700, the positioning rod 300 moves up and down reciprocally. At this time, the positioning cone 310 continuously inserts into the soil below the cone cylinder 110, making it easier to lower the mounting pipe 100. Simultaneously, when... When the monitoring equipment needs to be disassembled, first pull the first mounting ring 130 and the second mounting ring 320 upwards. Through the reaction of the surrounding soil on the inclined surface 611 of the limiting mechanism 600, the limiting block 610 extends into the monitoring hole 120, and the flat end of the top of the limiting block 610 releases its contact with the monitoring hole 120. At this time, under the reset action of the second reset spring 720 and the limiting spring 430, pulling the second mounting ring 320 upwards can quickly move the positioning cone 310 of the positioning rod 300 upwards to release the positioning, thereby achieving quick disassembly.

[0057] It is worth noting that when the positioning cone 310 needs to be continuously inserted into the soil below the cone cylinder 110, the up-and-down reciprocating movement of the positioning rod 300 does not need to be too large, so as not to affect the pressure sensor 500. At the same time, through the reset action of the second reset spring 720 and the limit spring 430, the positioning rod 300 can be easily and quickly moved up and reset, so that the positioning rod 300 can quickly move up and down.

[0058] Furthermore, mounting lugs 330 are symmetrically fixed to the upper periphery of the positioning rod 300, and the lugs 330 are fixedly connected to the bottom of the monitoring box 200 by bolts; the monitoring box 200 includes a monitoring box body 210 and a door 211 hinged to one side of the monitoring box body 210. The door 211 facilitates equipment maintenance, and the lugs 330 facilitate the installation or disassembly of the monitoring box 200.

[0059] A method for monitoring landslide disasters using the aforementioned monitoring equipment includes the following steps:

[0060] S1. By pressing down the first mounting ring 130, the mounting tube 100 is inserted into the soil. At this time, under the limit of the stop block 810, the positioning rod 300 follows the mounting tube 100 into the soil. During this process, the stop block 810 always abuts against the second limiting plate 440 below. The protective plate 410 seals the monitoring hole 120 so that the pressure sensor 500 is protected inside the mounting tube 100.

[0061] S2. If the installation pipe 100 encounters an obstacle and cannot move down during the process of moving down, the second installation ring 320 is controlled. Under the reset action of the second reset spring 720 of the auxiliary mechanism 700, the positioning rod 300 moves up and down repeatedly. At this time, the positioning cone 310 continuously inserts into the soil below the cone cylinder 110, making it easier for the installation pipe 100 to move down.

[0062] S3. After reaching the designated depth, the positioning rod 300 continues to move downward by pressing down the second mounting ring 320, and the positioning cone 310 is inserted into the deeper soil for positioning until the end of the inclined surface 611 of the limiting mechanism 600 is released from contact with the inner wall of the mounting tube 100. The inclined surface 611 extends out of the monitoring hole 120, and the flat end of the top of the limiting block 610 abuts against the monitoring hole 120. At this time, the limiting mechanism 600 and the limiting spring 430 together limit the housing of the pressure sensor 500, so that the pressure sensor 500 is aligned with the monitoring hole 120 to monitor the soil.

[0063] S4. When it is necessary to disassemble the monitoring equipment, first pull the first mounting ring 130 and the second mounting ring 320 upwards. Through the reaction of the surrounding soil on the inclined surface 611 of the limiting mechanism 600, the limiting block 610 extends into the monitoring hole 120.

8. A method for monitoring landslide disasters using the landslide disaster monitoring equipment described in any one of claims 1 to 7, characterized in that, Includes the following steps: S1. The first mounting ring (130) is pressed down to insert the mounting tube (100) into the soil. At this time, the positioning rod (300) follows the mounting tube (100) into the soil under the limit of the stop block (810). During this process, the stop block (810) always abuts against the second limiting plate (440) below. The protective plate (410) seals the monitoring hole (120) so that the pressure sensor (500) is protected inside the mounting tube (100). S2. If the installation pipe (100) encounters an obstacle and cannot move down during the process of moving down, the second installation ring (320) is controlled, and the positioning rod (300) moves up and down repeatedly under the reset action of the second reset spring (720) of the auxiliary mechanism (700). At this time, the positioning cone (310) continuously inserts into the soil below the cone cylinder (110), making it easier for the installation pipe (100) to move down. S3. After reaching the specified depth, the positioning rod (300) continues to move downward by pressing down the second mounting ring (320), and the positioning cone (310) is inserted into the deeper soil for positioning until the end of the inclined surface (611) of the limiting mechanism (600) is released from contact with the inner wall of the mounting tube (100). The inclined surface (611) extends out of the monitoring hole (120), and the flat end of the top of the limiting block (610) abuts against the monitoring hole (120). At this time, the limiting mechanism (600) and the limiting spring (430) together limit the housing of the pressure sensor (500) so that the pressure sensor (500) is aligned with the monitoring hole (120) to monitor the soil. S4. When it is necessary to disassemble the monitoring equipment, first pull the first mounting ring (130) and the second mounting ring (320) upwards. Through the reaction of the surrounding soil on the inclined surface (611) of the limiting mechanism (600), the limiting block (610) extends into the monitoring hole (120). The flat end of the top of the limiting block (610) releases from contact with the monitoring hole (120). At this time, under the reset action of the second reset spring (720) and the limiting spring (430), it moves upwards. Pulling the second mounting ring (320) causes the positioning cone (310) of the positioning rod (300) to move upward and release the positioning. At the same time, the protective plate (410) moves upward to close the monitoring hole (120) and protect the pressure sensor (500). Then, by continuing to pull the second mounting ring (320) upward, the positioning rod (300) and the mounting tube (100) move upward together to achieve disassembly under the limitation of the second limiting plate (440) by the stop block (810).
