Description

Technical Field

[0001] The invention relates to the technical field of mountain disaster monitoring devices, in particular to a landslide and mud-rock flow monitoring device. Background Art

[0002] Crack detectors are mainly used to monitor small changes in mountains, slopes or surfaces, which may be precursors to impending landslides or mud-rock flows. By accurately measuring the width and rate of change of cracks, crack detectors can provide key data on geological stability. These data are of great significance for analyzing the potential risks and predictions of landslides and mud-rock flows.

[0003] The prior art also has the following defects during use: The landslide and debris flow monitoring device in the prior art has high requirements for the installation environment during the detection process. When detecting in an outdoor environment, it is easily affected by changes in humidity and temperature, which causes a large deviation in the detection data, which directly affects the detection accuracy and reduces the prediction value of the detection data for landslide and debris flow. When the landslide and debris flow monitoring device in the prior art detects the width of the crack, due to the existence of a magnetic field of a certain strength in the outdoor environment, when using the electromagnetic field to judge the width of the crack, it is easy for the electromagnetic field generated by the device to interfere with the magnetic field in the environment, thereby affecting the detection effect of the device, and affecting the electronic components inside the device, resulting in less than ideal working stability of the device.

[0004] In view of this, we propose a landslide and debris flow monitoring device to solve the existing problems. Summary of the invention

DETAILED DESCRIPTION

[0016] The technical solution of the present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0017] like Figure 1 - Figure 7As shown, a landslide and debris flow monitoring device proposed by the present invention includes a first mounting frame 1, a fixing plate 2 and a second mounting frame 3. A fixing ring 102 is fixedly installed on the left side of the first mounting frame 1, and a sleeve 103 is fixedly installed on the right side of the first mounting frame 1. The sleeve 103 is a double-layer hollow cylindrical structure, and a plug-in slot is opened in the sleeve 103. A mounting hole is opened on the right side of the sleeve 103. An auxiliary coil 104 is fixedly installed inside the sleeve 103. The auxiliary coil 104 is made of a spiral non-magnetic conductive material. An electromagnetic inductor 105 is fixedly installed on the right side of the sleeve 103. The first mounting frame 1 is used to provide an installation position for surrounding components. The fixing ring 102 can be fixedly connected to the mountain or rock, so as to cooperate with the fixing plate 2 to fix the first mounting frame 1, so that after the first mounting frame 1 is fixed, it cooperates with the second mounting frame 3. When the cracks in the mountain change, the relative movement of the first mounting frame 1 and the second mounting frame 3 is used to judge the cracks. The width variation range is used to judge the probability of a landslide disaster. The sleeve 103 can be connected with the connecting tube 306 and provide an installation position for the internal components. The auxiliary coil 104 can cooperate with the electromagnetic coil 307 to heat the sleeve 103 and the internal components thereof, thereby keeping the temperature inside the device constant, avoiding the device being affected by the changes in the ambient temperature and humidity during detection and causing the detection accuracy to decrease, thereby ensuring the accuracy of the device for monitoring mountain cracks. The auxiliary coil 104 can also form a magnetic field shielding on one side of the electromagnetic sensor 105 inside the sleeve 103, and perform magnetic field shielding on the left side of the electromagnetic sensor 105, so that the electromagnetic sensor 105 detects the magnetic field on the right side of the connecting tube 306, and then judge the relative displacement range of the connecting tube 306 and the sleeve 103 through the change in the magnetic field strength, and then judge the change in the crack width, so as to obtain the probability of a landslide and a landslide at the installation position of the device. A connecting tube 306 is movably installed inside the plug slot, an electromagnetic coil 307 is fixedly installed inside the connecting tube 306, a current converter 301 is fixedly installed on the right side of the connecting tube 306, and a second mounting frame 3 is fixedly installed on the right side of the current converter 301. The connecting tube 306 can be connected to the sleeve 103, and one side of the connecting tube 306 is fixedly connected to the current converter 301. When the mountain crack expands, the distance between the first mounting frame 1 and the second mounting frame 3 increases, thereby causing the connecting tube 306 and the sleeve 103 to have a relative displacement. When the connecting tube 306 and the sleeve 103 are relatively displaced, the electromagnetic inductor 10 5 detects the change in the intensity of the magnetic field emitted by the electromagnetic coil 307, and then determines the change range of the width of the mountain crack. The current converter 301 adopts the DAT1135 type. The current converter 301 can convert the current between alternating current and direct current, so that the storage battery 305 releases electric energy to power other electronic components inside the device. The second mounting frame 3 can be fixedly connected to one side of the mountain crack, so that when the mountain moves, the second mounting frame 3 and the components around it are driven to move, so that the connecting tube 306 and the sleeve 103 are relatively displaced, and then the electromagnetic sensor 105 generates detection data; A fixing plate 2 is fixedly mounted at the bottom of the first mounting frame 1 and the second mounting frame 3 , and the fixing plate 2 can be connected to the first mounting frame 1 or the second mounting frame 3 , thereby ensuring the installation stability of the first mounting frame 1 and the second mounting frame 3 on the mountain surface.

[0018] Furthermore, a clip-on plate 101 is fixedly installed on the top of the first mounting frame 1. The clip-on plate 101 is an L-shaped plate, and a guide strip is provided on the top of the clip-on plate 101. The clip-on plate 101 can be snap-connected with the mounting plate 302, so that when the first mounting frame 1 and the second mounting frame 3 undergo relative displacement, the connection stability between the clip-on plate 101 and the mounting plate 302 can be ensured.

[0019] Furthermore, three collars 202 are installed inside the fixing plate 2. The collars 202 are semi-cylindrical structures. The collars 202 can be connected to the fixing plate 2, thereby facilitating the adjustment of the installation angle of the installation sleeve 204 so that the bottom of the device can be installed to adapt to the terrain.

[0020] Furthermore, a mounting sleeve 204 is fixedly installed at the bottom of the collar 202, a fixing seat 203 is fixedly installed at the bottom of the mounting sleeve 204, and the fixing seat 203 penetrates the mounting sleeve 204, a fixing anchor 201 is fixedly installed at the bottom of the fixing plate 2, and the fixing anchor 201 is a cone structure, and the mounting sleeve 204 can cooperate with the fixing seat 203 to fix the bottom of the fixing plate 2 to the mountain, so that the first mounting frame 1 is connected to the relatively stable mountain, and the second mounting frame 3 is connected to the part of the mountain where there is a crack, and the first mounting frame 1 and the second mounting frame 3 are respectively installed on both sides of the crack, and then when the crack expands, the expansion speed and amplitude of the crack can be judged by the relative displacement of the first mounting frame 1 and the second mounting frame 3, so as to judge the probability of landslide and mud-rock flow in the mountain.

[0021] Furthermore, a storage battery 305 is fixedly installed on the right side of the second mounting frame 3, a mounting plate 302 is fixedly installed on the top of the second mounting frame 3, a wireless signal transceiver 304 is fixedly installed on one side of the bottom of the mounting plate 302, and a solar panel 303 is fixedly installed on the top of the mounting plate 302. The storage battery 305 can be electrically connected to the solar panel 303, thereby storing electrical energy and providing electricity to the device. The mounting plate 302 can provide installation locations for surrounding components. The wireless signal transceiver 304 adopts the NRF24L01 type. The wireless signal transceiver 304 can wirelessly transmit the data detected by the device and transmit the detection data to the system end through the Internet, so as to facilitate the monitoring personnel to view and analyze the data sent back by several detection devices, so as to determine the probability of large-scale landslides and mudslides occurring in the mountain. The solar panel 303 can convert solar energy into electrical energy, thereby charging the storage battery 305.

[0022] Furthermore, a guide groove is opened inside the mounting plate 302, and the guide groove is engaged with the snap-in plate 101. The guide groove can be plugged into the guide bar to connect the mounting plate 302 with the snap-in plate 101, and when the mounting plate 302 and the snap-in plate 101 are relatively displaced with the first mounting frame 1 and the second mounting frame 3, the movement of the mounting plate 302 and the snap-in plate 101 is limited, thereby ensuring the structural stability of the overall device during operation.

[0023] Working principle: After detecting the crack position of the mountain, the installation position is selected, the first installation frame 1 is fixedly installed near the upper position of the mountain crack, and the second installation frame 3 is fixed at the lower position of the mountain, so that the first installation frame 1 and the second installation frame 3 are installed with a crack between them, and the solar panel 303 continuously converts solar energy into electrical energy to charge the battery 305, and the battery 305 then powers the device through the current converter 301, and the electromagnetic coil 307 is energized to generate an electromagnetic field. The electromagnetic sensor 105 detects the electromagnetic field emitted by the electromagnetic coil 307 at the same time, and the auxiliary coil 104 electromagnetically shields the left side of the electromagnetic sensor 105. At the same time, it is affected by the electromagnetic coil 307 and heated by electromagnetic heating to make the internal temperature of the sleeve 103 rise to the set range. The electromagnetic sensor 105 detects the electromagnetic field strength in a constant temperature environment; When the mountain changes and the crack width increases, the distance between the second mounting frame 3 and the first mounting frame 1 increases, causing the connecting tube 306 and the sleeve 103 to move relative to each other. At the same time, the electromagnetic sensor 105 and the electromagnetic coil 307 move relative to each other, and the magnetic field strength detected by the electromagnetic sensor 105 keeps changing. The probability of landslides and debris flows in the mountain is determined by the magnetic field strength data detected by the electromagnetic sensor 105, and the monitoring data is transmitted to the system platform through the wireless signal transceiver 304. The probability of large-scale disasters in the mountain is determined by the data transmitted by several groups of landslide and debris flow monitoring devices.
