The protection component 4 is located above the rainfall monitoring component 2 and protects the rainfall monitoring component 2.

[0025] The mobile assembly 1 includes a support body 11, a lower end of the support body 11 is screwed with an anchor rod 12, an upper end of the support body 11 is fixedly connected to a base 13, side panels 14 are symmetrically arranged on both sides of the support body 11, a gravity wheel 15 is rotatably installed on the opposite side of the side panel 14 and away from the support body 11, an auxiliary wheel 17 is rotatably installed on the side wall of the support body 11 and away from the side panel 14, the auxiliary wheel 17 and the gravity wheel 15 work together to support the support body 11 and keep the support body 11 off the ground, and a handrail frame 16 is fixedly installed on the side wall of the side panel 14 at a position corresponding to the gravity wheel 15.

[0026] The rainfall monitoring component 2 includes a liquid-carrying dish 21, which is fixedly installed on the middle part of the upper end of the support body 11, and arc-shaped support rods 22 are evenly installed on the upper edge of the liquid-carrying dish 21. The upper end of the arc-shaped support rod 22 is fixedly connected to a mounting seat 23, a sliding hole is opened in the middle of the mounting seat 23, and a pressure alarm 24 is fixedly arranged above the sliding hole, and the switch of the pressure alarm 24 is opposite to the sliding hole, and a coil spring 25 is fixedly connected to the middle part of the lower end surface of the mounting seat 23, and a floating plate 27 is fixedly connected to the lower end of the coil spring 25, and a vertical rod 26 is fixedly installed in the middle part of the upper end surface of the floating plate 27, and the vertical rod 26 is located on the inner side of the coil spring 25 and opposite to the sliding hole.

[0027] The side wall of the liquid carrying dish 21 is provided with leakage holes 211 evenly arranged along the circumference thereof near the upper end.

[0028] Furthermore, the protection component 4 includes a reinforcement rod 41, the reinforcement rod 41 is fixedly installed in the middle part of the inclined bracket 3, a lining plate 42 is fixedly installed on the reinforcement rod 41 near the end, the end of the lining plate 42 away from the reinforcement rod 41 is fixedly connected to the handrail frame 16, and an anti-collision plate 43 is fixedly installed between the opposite side walls of the lining plate 42. A circular through hole is opened on the anti-collision plate 43 at a position corresponding to the liquid carrier 21, a metal filter screen 44 is fixedly installed in the circular through hole, and a rain collecting cover 45 is installed at the lower end of the circular through hole. The rain collecting cover 45 is a funnel-shaped structure with a larger upper part and a smaller lower part.

[0029] In this embodiment, the pressure alarm 24 is connected to the terminal device, so that the staff can be informed of the alarm situation in time.

[0030] In the specific work, a platform for carrying the monitoring alarm device is first opened up manually on the half slope of the monitoring point, and then the monitoring alarm device is pushed manually to move it to the platform, and holes are drilled on the platform for installing anchor rods 12, so as to play a certain fixing role for the mobile component 1. The weight of the gravity wheel 15 can balance the weight of the monitoring alarm component 5, so that the monitoring alarm device is stable on the platform. During the monitoring process, the anti-collision plate 43 can play a certain protective role for the mobile component 1 and the rainfall monitoring component 2, thereby preventing the monitoring alarm device from being damaged by falling rocks. In rainy weather, the liquid-carrying dish 21 can collect rainwater. Under normal rainfall, when the rainwater level in the liquid-carrying dish 21 reaches the leakage hole 2 11 height, rainwater will leak out through the leakage hole 211. When the amount of water entering the liquid-carrying dish 21 per unit time is greater than the amount of rainwater discharged from the leakage hole 211, the rainwater level in the liquid-carrying dish 21 will continue to rise, and the rainwater can generate a certain buoyancy on the floating plate 27. As the rainwater level continues to rise, the force of the rainwater on the floating plate 27 will drive the floating plate 27 to move upward, the coil spring 25 is compressed, and the vertical rod 26 will also move upward. Finally, the upper end of the vertical rod 26 passes through the sliding hole and touches the switch of the pressure alarm 24. The pressure alarm 24 starts to alarm and transmits the alarm signal to the terminal device. At this time, it means that the rainfall is too heavy and a landslide may occur. The staff can issue an early warning signal in time according to the alarm signal.

[0031] Embodiment 2:

[0032] The technical solution is basically the same as that of the first embodiment, see Figure 1 , Figure 2 as well as Figures 6 to 13 The difference is that: the end of the inclined bracket 3 away from the moving component 1 is fixedly connected with a monitoring alarm component 5.

[0033] Specifically, the monitoring and alarm component 5 includes a horizontal plate 51, and the end of the inclined bracket 3 away from the support body 11 is fixedly connected to the horizontal plate 51, and rectangular through holes 52 are arranged in a linear manner on the horizontal plate 51, and a feedback unit 54 is arranged in the rectangular through hole 52. A monitoring column 55 is inserted into the lower end of the feedback unit 54, and the lower end of the monitoring column 55 is conical. A pillar 53 is fixedly installed at the corner of the upper end surface of the horizontal plate 51, and an alarm unit 56 is fixedly connected to the upper end of the pillar 53.

[0034] The feedback unit 54 includes a slide bar 541, which is fixedly installed in the rectangular through hole 52, and a shield plate 542 is slidably installed on the slide bar 541 through an extrusion spring 543. A photoelectric transmitter 544 is fixedly installed on the side of the rectangular through hole 52 and close to the inclined bracket 3, and a signal receiver 545 is fixedly installed on the other side of the rectangular through hole 52 corresponding to the position of the photoelectric transmitter 544. Vertical plates 546 are symmetrically installed on both sides of the lower end of the rectangular through hole 52, and a pin shaft 547 is fixedly installed on the opposite side of the vertical plate 546 near the lower end. A feedback rod 548 is rotatably arranged in the middle of the pin shaft 547, and a blind hole groove is opened at the upper end of the feedback rod 548. A shift block 5410 is slidably installed in the blind hole groove through an extension spring 549. The upper end of the shift block 5410 is slidably matched with the slide bar 541 and abuts against the side wall of the shield plate 542.

[0035] Furthermore, a plug hole matching with the lower end of the feedback rod 548 is provided at the upper end of the monitoring column 55 , a sleeve 551 is fixedly provided at the upper end of the outer wall of the monitoring column 55 , and guard plates 552 are symmetrically installed on both sides of the sleeve 551 .

[0036] The alarm unit 56 includes a ladder frame 561, the ladder frame 561 is fixedly installed on the upper end of the pillar 53, a solar panel 562 is fixedly arranged on the inclined surface of the ladder frame 561, and sound and light alarms 563 are linearly arranged on the side wall of the ladder frame 561 away from the inclined support 3. The sound and light alarms 563 are controlled by the controller on the signal receiver 545, and the signal receiver 545 and the solar panel 562 are electrically connected.

[0037] In the specific work, after arriving at the monitoring point, the monitoring column 55 is first manually chiseled into the landslide slope, so that the lower end of the guard plate 552 is close to the landslide slope. The guard plate 552 can intercept the rubble and soil rolling down the mountain slope, thereby avoiding the hidden danger of falling rocks. Then the lower end of the feedback rod 548 is inserted into the upper end of the monitoring column 55; During the monitoring process, before a landslide occurs in the mountain, the soil inside the mountain will first move, and the soil inside will exert pressure on the monitoring column 55 and transmit it to the feedback rod 548, so that the feedback rod 548 and the monitoring column 55 move around the pin 547 in the direction away from the slope surface, and at the same time, the upper end of the feedback rod 548 moves in the direction close to the slope surface, thereby driving the shift block 5410 to squeeze the shield plate 542, and the shift block 5410 drives the shield plate 542 to move in the direction close to the photoelectric transmitter 544, and the extrusion spring 543 is compressed. When the shield plate 542 moves to the photoelectric transmitter 544 and the signal interface 544, the feedback rod 548 moves to the feedback axis 547, and the feedback rod 548 moves to the feedback axis 547. When the position between the signal receiver 545 and the photoelectric transmitter 544 is reached, it means that the soil inside the mountain has been displaced too much and a landslide may occur. Due to the shielding effect of the shield 542, the signal receiver 545 can no longer receive the photoelectric signal emitted by the photoelectric transmitter 544. At this time, the controller connected to the signal receiver 545 will turn on the sound and light alarm 563 and emit a sound and light alarm, thereby warning and promptly persuading people passing by under the monitoring point to leave and avoid personal injury. At the same time, the sound and light alarm signal emitted by the sound and light alarm 563 will also be transmitted to the terminal, so that the staff can take emergency measures in time.

[0038] In addition, the present invention also provides a landslide monitoring and alarm system, the monitoring and alarm system comprising: Data acquisition module: The physical parameters of landslides are collected in real time through monitoring and alarm devices deployed on the slope surface of the mountain; Data transmission module: transmits the monitoring data collected by the data acquisition module to the data processing center through satellite or optical fiber communication equipment; Data processing and analysis module: Use statistical analysis and machine learning algorithms to process and analyze monitoring data, identify abnormal changes and potential risks of landslides, and establish early warning models to predict the possibility and time of landslides; Warning release module: Different warning levels are divided according to the size of landslide risks and fed back to the data receiving center through multiple channels; Remote monitoring and management module: The remote monitoring interface provides an intuitive graphical interface, allowing managers to remotely view the status and monitoring data of the landslide in real time.

[0039] The working principle of the present invention when in use:

[0040] One: First, a platform for carrying the monitoring alarm device is opened up manually on the half slope of the monitoring point, and then the monitoring alarm device is pushed manually to move it to the platform, and holes are drilled on the platform for installing anchor rods 12, so as to play a certain fixing role for the mobile component 1. The weight of the gravity wheel 15 can balance the weight of the monitoring alarm component 5, so that the monitoring alarm device is stable on the platform. During the monitoring process, the anti-collision plate 43 can play a certain protective role for the mobile component 1 and the rainfall monitoring component 2, thereby preventing the monitoring alarm device from being damaged by falling rocks. In rainy weather, the liquid-carrying dish 21 can collect rainwater. Under normal rainfall, when the rainwater level in the liquid-carrying dish 21 reaches the leakage hole 211 After the height reaches 400°, rainwater will leak out through the leakage hole 211. When the amount of water entering the liquid-carrying dish 21 per unit time is greater than the amount of rainwater discharged from the leakage hole 211, the rainwater level in the liquid-carrying dish 21 will continue to rise, and the rainwater can generate a certain buoyancy on the floating plate 27. As the rainwater level continues to rise, the force of the rainwater on the floating plate 27 will drive the floating plate 27 to move upward, the coil spring 25 is compressed, and the vertical rod 26 will also move upward. Finally, the upper end of the vertical rod 26 passes through the sliding hole and touches the switch of the pressure alarm 24. The pressure alarm 24 starts to alarm and transmits the alarm signal to the terminal device. At this time, it means that the rainfall is too heavy and a landslide may occur. The staff can issue an early warning signal in time according to the alarm signal.

[0041] 2. When arriving at the monitoring point, first manually chisel the monitoring column 55 into the landslide slope so that the lower end of the guard plate 552 is close to the landslide slope. The guard plate 552 can intercept the gravel and soil rolling down the mountain slope, thereby avoiding the risk of falling rocks. Then, the lower end of the feedback rod 548 is inserted into the upper end of the monitoring column 55.

[0042] 3. During the monitoring process, before a landslide occurs in the mountain, the soil inside the mountain will first move, and the soil inside will exert pressure on the monitoring column 55 and transmit it to the feedback rod 548, so that the feedback rod 548 and the monitoring column 55 move around the pin 547 in the direction away from the slope surface, and at the same time, the upper end of the feedback rod 548 will move in the direction close to the slope surface, thereby driving the shift block 5410 to squeeze the shield plate 542, and the shift block 5410 drives the shield plate 542 to move in the direction close to the photoelectric transmitter 544, and the extrusion spring 543 is compressed. When the shield plate 542 moves to the photoelectric transmitter 544 and the signal When the position between the receiver 545 is reached, it means that the soil displacement inside the mountain is too large and a landslide may occur. Due to the shielding effect of the baffle 542, the signal receiver 545 can no longer receive the photoelectric signal emitted by the photoelectric transmitter 544. At this time, the controller connected to the signal receiver 545 will turn on the sound and light alarm 563 and emit a sound and light alarm, thereby warning and promptly persuading people passing by under the monitoring point to leave to avoid personal injury. At the same time, the sound and light alarm signal emitted by the sound and light alarm 563 will also be transmitted to the terminal, so that the staff can take emergency measures in time.

[0043] Finally, it should be noted that in order to more comprehensively reflect the displacement of the soil at the monitoring point, the monitoring column 55 can be made into different lengths. When monitoring columns 55 of different lengths are selected, soil at different depths can be monitored. However, no matter what length of the monitoring column 55 is selected, its upper end should meet the normal use of the feedback rod 548.
