A first slider 8 is slidably provided on the linear slide 901. The first slider 8 is wrapped with a sealing layer. The sealing layer is used to seal the sensing window 101 when the first slider 8 is inserted into the sensing window 101. The lower end of the first slider 8 is connected to the central axis of the roller; the soil monitoring part is arranged on the first slider 8, and is used to detect the pressure and humidity of the soil at the sensing window 101; the driving component is arranged on the base 2, and is connected to the rotating shaft 7, and is used to drive the turntable 5 to rotate, so as to drive the soil monitoring part to extend into the sensing window 101.

[0040] The present embodiment provides a flash flood danger zone warning and forecasting device. Compared with the prior art, the present invention adds a hollow pile rod 1, which can be drilled or buried deep into the ground. A sensing window 101 is provided on the rod wall of the pile rod 1. A rotating shaft 7 is rotatably arranged in the pile rod 1. A rotating disk 5 is arranged on the rotating shaft 7. The depth of the rotating disk 5 is determined according to the soil depth to be monitored. A spiral guide groove 501 is provided on the rotating disk 5. A roller is arranged to roll in the spiral guide groove 501. A linear slide 901 is provided on the slide frame 9 above the rotating disk 5. A first slider 8 is slidably arranged on the linear slide 901, and a second slider 8 is slidably arranged on the linear slide 901. The lower end of a slider 8 is connected to the central axis of the roller, and a soil monitoring unit is provided on the first slider 8. When the rotating shaft 7 drives the turntable 5 to rotate, the first slider 8, which can only slide in a straight line, is connected to the roller in the spiral guide groove 501. When the spiral guide groove 501 is farther and farther away from the center of the turntable 5, the first slider 8 can be pushed to move in a direction away from the center of the turntable 5, so that the first slider 8 wrapped with a sealing layer extends into the sensing window 101 to seal the sensing window 101. At the same time, the soil monitoring unit on the first slider 8 can contact the soil through the sensing window 101 to monitor the soil.

By monitoring and analyzing the humidity and pressure of the underground soil, the mountain torrent danger can be predicted in advance, and sufficient time for people to escape from the mountain torrent danger area can be prepared. At the same time, during use, the turntable 5 can be controlled to rotate according to the actual situation, and the position of the soil monitoring unit can be fine-tuned to ensure the accuracy of monitoring.

[0041] In this embodiment, a through hole is provided on the base 2, the driving assembly is provided on the base 2, and the rotating shaft 7 passes through the through hole on the base 2 and is connected to the driving assembly. A hollow pillar 21 is provided on the base 2, and the driving assembly is located in the pillar 21. The driving assembly can be a driving motor or a manually operated rotating handle. When it is a manually operated rotating handle, the staff can rotate the rotating shaft 7 by rotating the rotating handle.

[0042] In this embodiment, the soil monitoring unit includes a pressure sensing element and a humidity sensing element, both of which are located at one end of the first slider 8 inserted into the sensing window 101. The pressure sensing element may be a pressure sensor, and the humidity sensing element may be a soil humidity sensor.

[0043] In this embodiment, the first slider 8 is a long strip structure. When the first slider 8 is extended, the outer end of the first slider 8 protrudes from the outer wall of the pile rod 1 by a preset distance, which can be 1-3 cm, to prevent the pressure sensing element and the humidity sensing element from being too close to the pile rod 1 and being affected by the pile rod 1 during monitoring.

[0044] In this embodiment, the extension line of the linear slideway 901 passes through the center of the turntable 5 , and the first sliding block 8 can move in the radial direction of the turntable 5 .

[0046] In this embodiment, multiple sets of rotating disks 5, slide frames 9, and first sliders 8 are arranged along the axial direction of the rotating shaft 7, so that soils at different depths can be monitored synchronously, thereby comprehensively analyzing and judging to ensure the accuracy of the judgment. Moreover, the moving directions at different depths do not have to be the same, so that the soil monitoring unit can monitor soils at different depths and in different directions.

[0047] like Figures 3 to 6 As shown, a specific implementation method provided by the present invention on the basis of the first implementation method is as follows: a plurality of identical spiral guide grooves 501 are arranged on each turntable 5, and the plurality of spiral guide grooves 501 are evenly arranged along the circumferential direction, a roller is rotatably arranged in each spiral guide groove 501, a plurality of linear slideways 901 are evenly arranged along the circumferential direction on the slideway frame 9, and the number of the linear slideways 901 is the same as the number of the spiral guide grooves 501, a first slider 8 is slidably arranged in each linear slideway 901, the first slider 8 is connected to the roller in a one-to-one correspondence, a soil monitoring part is arranged on each first slider 8, and a plurality of sensing windows 101 are arranged on the rod wall of the pile rod 1, and the sensing windows 101 correspond to the soil monitoring parts in a one-to-one manner.

[0048] In this embodiment, through ingenious size and structural design, multiple identical spiral guide grooves 501 are arranged on the same turntable 5, and the identical spiral grooves are evenly arranged along the circumferential direction without interference.

The end points of two spiral guide grooves 501 whose starting points are on the same diameter line of the turntable 5 are also located on the same diameter line of the turntable 5. In this embodiment, the slide frame 9 is a cross structure, and a through hole is provided in the middle of the slide frame 9, and the rotating shaft 7 passes through the through hole. A linear slide 901 is arranged on each branch of the slide frame 9, and each linear slide 901 is arranged along the radial direction of the turntable 5, and the first slider 8 can slide along the radial direction of the turntable 5. Through a simple structural design, rotating a turntable 5 can simultaneously control the four first sliders 8 to move synchronously by the same distance, so that the four soil monitoring parts are simultaneously inserted into the four sensing windows 101 respectively, and the soil in different directions at the same depth can be monitored.

[0050] In this embodiment, a plurality of turntables 5 are arranged along the axial direction of the rotating shaft 7, and a turntable 5 is arranged at different depth layers. Four spiral guide grooves 501 are arranged on each turntable 5, and a cross-structured slide frame 9 is arranged above each turntable 5. A linear slide 901 is arranged on each branch of the slide frame 9, and a first slider 8 is arranged on each linear slide 901, so that the pressure and humidity of the soil at different depths and directions can be monitored.

[0051] like Figure 5 As shown, a specific embodiment provided by the present invention on the basis of the first embodiment is as follows: an arc-shaped connecting frame 10 is provided on the outer cover of the turntable 5, the connecting frame 10 is rotatably connected to the turntable 5, the connecting frame 10 is connected to the vertical frame rod 6, a socket is provided on the base 2, the upper end of the vertical frame rod 6 is inserted into the socket, the slide frame 9 is connected to the connecting frame 10, and the slide frame 9 is connected to the base 2 through the connecting frame 10 and the vertical frame rod 6.

[0052] In this embodiment, by setting a socket on the base 2 and inserting the vertical frame rod 6 connected to the connecting frame 10 into the socket, the direction of the soil monitoring part on the first slider 8 can be positioned, so that the soil monitoring part can be smoothly extended into the sensing window 101 by controlling the movement of the turntable 5.

Two guide holes are provided on the cover plate 26, and the upper end surface of the cover plate 26 is a frustum, which is used to introduce rainwater into the inner cylinder 14; the filter plate 3 is located in the outer cylinder 4, and is arranged above the inner cylinder 14, and two rod holes are provided on the filter plate 3; the filter screen 24 is located in the outer cylinder 4, and is arranged above the filter plate 3, and the two sides of the filter screen 24 are respectively ball-hinged with two second sliders 27; the ejection mechanism is arranged between the outer cylinder 4 and the inner cylinder 14, and the ejection mechanism has two ejection rods 11, and the upper ends of the two ejection rods 11 respectively pass through the two rod holes and the two guide holes in sequence to be rotatably connected with the filter screen 24, and the guide holes are used to limit the ejection rod 11 to only move vertically, and the ejection mechanism is used to push the filter screen 24 to move along the slide rail 25 to extend out of the outer cylinder 4, and vibrate and tilt to remove debris.

[0058] Specifically, the filter screen 24 is a flexible screen structure, the inner side of which can be supported by a hard frame. Under the support of the hard frame, the filter screen 24 can be a planar structure or a structure with a convex middle portion, so as to shake off debris such as fallen leaves.

[0059] In the prior art, a warning and forecasting device for flash flood danger areas generally needs to be equipped with a rainwater meter. However, because it is an outdoor environment, fallen leaves and the like often fall into the rainwater meter, blocking the water inlet of the rainwater meter, affecting the detection accuracy, thereby affecting the prediction result of flash flood danger. In this embodiment, the rainwater monitor is additionally provided with an outer cylinder 4 and an inner cylinder 14 arranged in the outer cylinder 4, the rainwater meter body is arranged in the inner cylinder 14, and the space between the outer cylinder 4 and the inner cylinder 14 is closed by a cover plate 26 of an annular structure. A filter plate 3 is arranged on the cover plate 26, and a filter screen 24 is arranged on the filter plate 3. At the same time, the upper end of the outer cylinder 4 is higher than the upper end of the inner cylinder 14, which can prevent the rainwater from rebounding and flying out of the outer cylinder 4 after contacting the filter plate 3 and the filter screen 24, and can collect all the rainwater in the outer cylinder 4, ensuring that the detection data is more accurate. The upper end surface of the cover plate 26 is a round table surface, and the rainwater falling on the cover plate 26 can be drained into the rainwater meter body of the inner cylinder 14. In this embodiment, a filter plate 3 is provided on the basis of the filter screen 24. In view of the actual working environment, the filter screen 24 is easily damaged under long-term sunlight, so the filter screen 24 plus the filter plate 3 can provide double protection to prevent debris from clogging the water inlet of the rain gauge body. At the same time, the filter screen 24 is light in weight, which is convenient for the push mechanism to push and clean the debris or fallen leaves on the filter screen 24.

[0060] In this embodiment, the rainwater meter body can be a bucket-type rainwater meter available on the market.

[0061] like Figures 7 to 13As shown, the present invention provides a specific embodiment based on the above embodiment as follows: the push mechanism includes a basic ring 19, an outer ring gear 15, a plurality of pin bodies 16, two internal gears 20, two cams 12, a driving gear 17 and a driver, the basic ring 19 is connected to the inner wall of the outer cylinder 4; the outer ring gear 15 is rotatably arranged on the basic ring 19 and is coaxially arranged with the basic ring 19; a plurality of pin bodies 16 are evenly arranged on the upper end of the outer ring gear 15 along the circumferential direction; the outer ring gear 15 passes through the inner holes of the two internal gears 20, and the connecting line of the two internal gears 20 passes through the center of the outer ring gear 15, the internal gear 20 has the freedom to rotate around its own axis, the internal gear 20 is a helical gear structure, and the pin bodies 16 are inserted into the gear teeth of the internal gear 20 to push the outer ring gear 15. The inner gear 20 rotates; the two cams 12 are respectively mounted on the two inner gears 20 and can rotate with the inner gear 20. The outer wall of the cam 12 is provided with a low section 1203, a push section 1202 and a vibration section 1201 which are connected in sequence. The two cams 12 are respectively in contact with the lower ends of the two push rods 11. The low section 1203 is used to maintain the filter 24 in a horizontal state in the outer cylinder 4. The push section 1202 is used to push the push rod 11 to move upward and make the filter 24 extend out of the outer cylinder 4. The vibration section 1201 is used to push the filter 24 to shake and cause debris to fall off; the driving gear 17 is meshed with the outer ring gear 15; the driver is fixed on the outer cylinder 4, and the power output end is connected to the driving gear 17, which is used to drive the outer ring gear 15 to rotate.

[0062] In this embodiment, through a simple structural design, two or even more internal gears 20 can be rotated synchronously. In this embodiment, a rotating outer ring gear 15 is provided, and a plurality of pin bodies 16 are provided on the outer ring gear 15, and the pin bodies 16 are evenly arranged along the circumferential direction. At the same time, two internal gears 20 that can rotate around their own axes are provided. The internal gears 20 are helical gear structures. When the outer ring gear 15 rotates, it passes through the inner holes of the two internal gears 20, so that the pin bodies 16 on the outer ring gear 15 enter the gear teeth of the internal gear 20. When one of the pin bodies 16 rotates out of the gear teeth of the internal gear 20, the next pin body 16 rotates into the next gear tooth of the internal gear 20, and the pin body 16 can push the internal gear 20 to rotate, thereby driving the external cam 12 of the internal gear 20 to rotate. Under the action of gravity, the lower end of the ejector rod 11 is always in contact with the cam 12.

[0063] In this embodiment, the two inner gears 20 rotate synchronously in opposite directions. When one rotates clockwise, the other rotates counterclockwise. When it rains, the low sections 1203 of the two cams 12 contact the ejection rod 11, and the filter 24 is located in the outer cylinder 4 and is horizontally arranged above the filter plate 3. When it is about to rain, the controller drives the gear 17 to rotate, driving the two cams 12 to rotate to the ejection section 1202 first. At this time, the ejection rod 11 moves upward, and the second ejection slider 27 slides along the slide rail 25, so that the filter 24 rises and moves to the top of the outer cylinder 4. Then the two cams 12 continue to rotate, and the push rod 11 contacts the vibration section 1201. When one of the cams 12 is located at the wave crest of the vibration section 1201, the other cam 12 is located at the wave trough of the vibration section 1201, so that the two push rods 11 are at different heights, and the filter 24 rotates and tilts; then the cam 12 just located at the wave crest enters the wave trough, and the other cam 12 just located at the wave trough enters the wave crest, and so on, so that the filter 24 rotates and shakes continuously, clearing the fallen leaves on the filter 24, and preparing for the subsequent monitoring of rainwater. When the shaking is completed, the two cams 12 return to the low section 1203 again, and the filter 24 is retracted into the outer cylinder 4.

[0064] like Figures 9 to 13 As shown, the present invention provides a specific embodiment based on the above embodiment as follows: the ejection mechanism also includes two connecting sleeves 18, each connecting sleeve 18 is respectively sleeved with an internal gear 20, and a through groove 1802 is provided in the middle of the connecting sleeve 18, and the outer ring gear 15 and the pin body 16 pass through the internal gear 20 through the through groove 1802.

[0065] In this embodiment, the connecting sleeve 18 is composed of two half sleeves 1801 assembled and connected. The basic ring 19 passes through the through groove 1802 of the connecting sleeve 18, and the bottom end of the through groove 1802 is connected to the basic ring 19. The basic ring 19 is also provided with an inner ring 13, and the inner ring 13 is connected to the side wall of the through groove 1802, so as to fix the connecting sleeve 18. This connection method has a simple structure and is easy to disassemble.

[0066] like Figure 1 As shown, a specific embodiment provided by the present invention on the basis of the above-mentioned embodiment is as follows: a support 21 is provided at the upper end of the base 2, and a rain monitor, a solar panel 23 and an electric control box 22 are provided on the support 21. The electric control box 22 is provided with a controller, an alarm, a data transmission module and a battery. The controller is electrically connected to the soil monitoring part, the rain monitor, the driver of the driving gear 17, the alarm, the data transmission module and the battery respectively, and the solar panel 23 is electrically connected to the battery.

[0067] In this embodiment, the controller controls the driver of the driving gear 17 according to a preset program. Before it rains, the driver makes the push-up section 1202 and the vibration section 1201 of the cam 12 contact the push-up rod 11, so that the filter 24 extends out of the outer tube 4 to shake, remove debris, and prepare for rainwater metering; when it rains, the driver makes the low section 1203 of the cam 12 contact the push-up rod 11, and the filter 24 is located in the outer tube 4, parallel to the filter plate 3. The battery is charged by the solar panel 23 and used to power various electrical devices; the data transmission module is used to send and receive data so that the remote control terminal can obtain monitoring data and send control instructions; when the soil monitoring unit detects that the pressure and humidity changes of the soil exceed the preset value range, or the precipitation and precipitation rate detected by the rain monitor exceed the preset value range, the controller controls the alarm and the data transmission module to send an alarm signal.

[0068] Based on the same inventive concept, the embodiment of the present application also provides a flash flood danger zone warning and forecasting method, comprising the following steps:

[0069] S100, installing the flash flood danger zone warning and forecasting device as described in the above scheme; specifically, inserting the rotating shaft 7 with the rotating disk 5, the slide frame 9, and the soil monitoring part into the pile rod 1, and connecting the rotating shaft 7 with the pile rod 1, driving the rotating disk 5 to rotate, so as to drive the soil monitoring part to move and insert into the sensing window 101 of the pile rod 1; drilling or burying the pile rod 1 into the ground, connecting the base 2 with the pile rod 1, the slide frame 9, and the rotating shaft 7, and driving the rotating disk 5 to rotate through the rotating shaft 7, and adjusting the extended position of the soil monitoring part so that the soil monitoring part contacts the soil; installing the pillar 21 and the rain monitor, the solar panel 23 and the electric control box 22;

[0070] S200: When the soil monitoring unit detects that the pressure and humidity changes of the soil exceed the preset value range, or the precipitation amount and precipitation rate detected by the rain monitor exceed the preset value range, the controller controls the alarm and the data transmission module to send out an alarm signal.

[0071] Compared with the prior art, the present embodiment provides a flash flood danger zone warning and forecasting method. First, the rotating shaft 7, the rotating disk 5, the slide frame 9, the soil monitoring part and the pile rod 1 are assembled. The rotating shaft 7 drives the rotating disk 5 to rotate, so as to drive the soil monitoring part to move and insert into the sensing window 101 of the pile rod 1. When the pile rod 1 is inserted into the ground by drilling or burying, the driving component drives the rotating disk 5 to rotate through the rotating shaft 7, and fine-tunes the position of the soil monitoring part to ensure that the soil monitoring part is in contact with the soil, so as to accurately monitor the humidity and pressure of the soil deep underground in real time. The controller analyzes and issues early warning of flash flood disasters, so that people in the flash flood danger zone have enough time to prepare for evacuation.

[0072] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
