Technical Field

[0001] This utility model relates to the field of monitoring and sampling technology, specifically to a rainfall warning device for geological disaster risk. Background Technology

[0002] In geological disaster prevention and control, rainfall is one of the important triggers for many geological disasters such as landslides and debris flows. At present, the early warning methods for geological disasters related to rainfall mainly focus on professional meteorological monitoring departments transmitting rainfall data and disaster risk levels to relevant departments through numerical forecasts and data release platforms, or setting up early warning notices in some key areas based on sensor detection data being transmitted back to the monitoring center for analysis and judgment.

[0003] Chinese patent (CN209132449U) discloses an automatic rainfall monitoring and recording device and a rainwater sampling device. This device can automatically record rainfall during rainfall, automatically sample, and alert the user to replace the standard sampling bottle. Compared with manual sampling, it greatly improves the level of automation. However, its monitoring efficiency is not high, which affects its ability to warn of geological disasters. Therefore, this utility model proposes a warning device that can intuitively display the corresponding geological disaster risk level in real time based on rainfall, so that people can react quickly and reduce the harm that geological disasters may cause. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the shortcomings of the low monitoring efficiency of existing rainfall warning devices for geological disaster risks, and thus provide a rainfall warning device for geological disaster risks.

[0005] To address the aforementioned problems, this utility model provides a rainfall warning device for geological disaster risk, comprising:

[0006] The cylinder has a first collecting plate at its top, a first collecting hole at the center of the first collecting plate to allow rainwater to enter the cylinder, and a drain outlet at its bottom to discharge rainwater from the cylinder.

[0007] The second collecting plate divides the cylinder into two cavities distributed vertically, and a second collecting hole is provided at the center of the collecting plate;

[0008] Monitoring devices are respectively installed below the first collection hole and / or the second collection hole for monitoring;

[0009] The control device controls the monitoring institutions to perform monitoring respectively. The control device is also connected to an alarm mechanism, which is used to warn whether rainfall will cause geological disasters based on the monitoring structure of the monitoring institutions.

[0010] Preferably, the top of the first collecting plate and the second collecting plate are respectively provided with collecting grooves, and the collecting grooves are in the shape of a frustum.

[0011] Preferably, a limiting groove is provided at the edge of the first collection hole, and a filter plate is provided inside the first collection hole. The filter plate and the limiting groove are detachably connected.

[0012] Preferably, at least three legs are evenly arranged at the bottom of the cylinder with the center of the cylinder as the center, and each leg has a sharp end at its bottom.

[0013] Preferably, the monitoring mechanism includes: a base plate and a swing block, the swing block being located directly below the first collection hole and / or the second collection hole, and the swing block being located above the base plate with a gap between them;

[0014] A pair of first connecting rods are provided at the middle of the front and rear edges near the bottom plate. One end of the first connecting rod is connected to the bottom plate, and the other end of the first connecting rod is rotatably connected to the middle of the swing block. A second connecting rod is connected between the first connecting rod and the inner wall of the cylinder.

[0019] The rainfall warning device for geological disaster risk provided by this utility model has the following beneficial effects:

[0020] 1. This utility model enables the rapid and accurate acquisition of relatively accurate rainfall monitoring data in real time by having a second monitoring agency provide a reference for the accuracy of the data while the first monitoring agency monitors it.

[0021] 2. This utility model also utilizes the following method: When rainwater flows downward through the first or second collection hole and falls into the collection trough, the collection trough will deflect due to the impact of the rainwater. When the swing block deflects to one side, the collection trough on the other side rotates to below the first or second collection hole and begins to collect rainwater. When it is full, the balance is broken, and the swing block deflects from the previous side to the other side. The collection trough on the side that was previously deflected begins to collect rainwater. When it is full, the balance is broken again. This process of collecting rainwater is repeated. The frequency of the swing block's swing per unit time is used to measure the amount of rainfall.

[0022] 3. This utility model also establishes a geological disaster level corresponding to the threshold by dividing the monitoring agency into thresholds, thereby providing a warning to people in the vicinity of potential geological disaster risk areas, making it easier for people to take timely avoidance or prevention measures, and enhancing the intuitiveness and timeliness of on-site geological disaster early warning.

[0029] like Figure 1-4 As shown, this utility model provides a rainfall warning device for geological disaster risk, which includes:

[0030] The cylinder 1 has a first collecting plate 2 at its top and a first collecting hole 4 at its center to allow rainwater to flow into the cylinder 1. The bottom of the cylinder 1 has a drain outlet 5 for discharging rainwater from the cylinder 1.

[0031] The second collecting plate 3 divides the inside of the cylinder 1 into two cavities distributed vertically, and a second collecting hole 6 is provided at the center of the collecting plate.

[0032] The monitoring devices are respectively installed below the first collection hole 4 and / or the second collection hole 6 for monitoring;

[0033] A control device controls the monitoring mechanisms to perform monitoring respectively. The control device is also connected to an alarm mechanism 7, which is used to warn of whether rainfall will cause geological disasters based on the monitoring structure of the monitoring mechanisms. Figure 1-4 As shown, a rainfall warning device for geological disaster risk has a segmented structure for its cylinder 1. The upper part is a transparent polycarbonate pipe section with a diameter of 300mm, and the lower part is a steel pipe section with a diameter of 400mm, with a total height of 1.2m. The first collection plate 2 at the top of the cylinder 1 is a 304 stainless steel disc with a thickness of 5mm and a first collection hole 4 with a diameter of 80mm in the center. The first collection plate 2 and the second collection plate 3 can be connected to the inner wall of the cylinder 1 by snap-fit ​​or bolt connection. The first collection hole 4 is provided with an annular limiting groove, and a PP material filter plate 8 can be detachably installed. The filter plate 8 has a filter hole diameter of 2mm. The cylinder 1 provides a stable monitoring environment. After monitoring, the rainwater is discharged through the drain outlet 5 at the bottom of the cylinder 1. The location of the monitoring mechanism can be selected based on the actual situation, such as below the first collection hole 4 or below the second collection hole 6, or both below the first collection hole 4 and the second collection hole 6. While the first monitoring mechanism monitors, the second monitoring mechanism provides a reference for the accuracy of its data, enabling the rapid and accurate acquisition of relatively accurate rainfall monitoring data in real time, thereby improving monitoring efficiency. The control device is commercially available. The main control chip of the control device is an STM32F407 with a sampling frequency of 100Hz. The control device connects to a processor and a communication module, both of which are commercially available. The processor is used for the conversion of sensor signals and data processing, while the communication module is used for 5G / WIFI dual-mode transmission of alarm signals and for establishing a connection with the remote control terminal.

[0034] In some embodiments, the tops of the first collecting plate 2 and the second collecting plate 3 are respectively provided with collecting grooves, and the collecting grooves are frustum-shaped. For example... Figure 1-4 As shown, the collection troughs of the first collection plate 2 and the second collection plate 3 are both frustum-shaped to facilitate the rapid collection of rainwater into the first collection hole 4 and the second collection hole 6. The bottom of the collection trough is coated with a hydrophobic coating.

[0035] In some embodiments, a limiting groove is provided at the edge of the first collection hole 4, and a filter plate 8 is provided inside the first collection hole 4. The filter plate 8 and the limiting groove are detachably connected. Figure 1-4As shown, the filter plate 8 and the first collection hole 4 can be connected by bonding, snap-fitting or bolting. The filter plate 8 is made of PP material and has a filter hole diameter of 2mm. It can prevent impurities in the environment from entering the cylinder 1, such as preventing branches or sand particles from affecting the accuracy of measurement.

[0036] In some embodiments, at least three legs 9 are evenly arranged at the bottom of the cylinder 1 with the center of the cylinder 1 as the center, and the bottom of each leg 9 is provided with a sharp end. For example Figure 1-4 As shown, the three support legs 9 at the bottom of the cylinder 1 are distributed at 120° and are made of φ20mm threaded steel. The tips are hardened to form sharp ends with an acute angle of 60°, so that they can be inserted into the ground to provide stable support for the cylinder 1. Before use, the level of the cylinder 1 needs to be adjusted to avoid affecting the accuracy of monitoring.

[0037] In some embodiments, the monitoring mechanism includes: a base plate 10 and a swing block 11, the swing block being located directly below the first collection hole 4 and / or the second collection hole 6, and the swing block 11 being located above the base plate 10 with a gap between them;

[0038] A pair of first connecting rods 12 are provided at the middle of the front and rear edges near the bottom plate 10. One end of the first connecting rod 12 is connected to the bottom plate 10, and the other end of the first connecting rod 12 is rotatably connected to the middle of the swing block 11. Second connecting rods 13 are connected between the first connecting rod 12 and the inner wall of the cylinder 1. Figure 1-4 As shown, the monitoring mechanism is installed below the first collection hole 4 and / or the second collection hole 6, with the base plate 10 and the inner wall of the cylinder 1 connected by bonding or snap-fitting. A gap is pre-set between the base plate 10 and the inner wall of the cylinder 1 to allow water to flow through. The first connecting rod 12 and the swing block 11 are rotatably connected. When rainwater flows down through the first collection hole 4 or the second collection hole 6 and falls into the collection trough 14, the collection trough 14 will deflect due to the impact of the rainwater. When the swing block 11 deflects to one side, the collection trough 14 on the other side rotates to the bottom of the first collection hole 4 or the second collection hole 6 and begins to collect rainwater. When it is full, the balance is broken, and the swing block 11 deflects from the previous side to the other side. The collection trough 14 on the side that was previously deflected begins to collect rainwater. When it is full, the balance is broken again. This process of collecting rainwater is repeated. The frequency of the swing block 11's swing per unit time is used to measure the rainfall.

[0039] In some embodiments, the cross section of the swing block 11 along both sides is an isosceles triangle, and the two sides of the swing block 11 are symmetrically provided with collection slots 14.

[0040] Pressure sensors 15 are symmetrically arranged on the bottom plate 10 below one end of the collection groove 14 near the inner wall of the cylinder 1. Each pressure sensor 15 is connected to the processor of the control device. Figure 1-4 As shown, the collection slots 14 of the swing block 11 on both sides facilitate the collection of rainwater. When the rainwater in the collection slots 14 on both sides is different, the balance will be broken and the block will deflect to one side. At the same time, the rainwater on the deflected side will be poured out, and the other side will collect rainwater again. This cycle is repeated to count the rainfall. The time of the cycle is calculated as two deviations of the swing block 11. The rainfall is measured by the amount of rainwater collected in the two collection slots 14. The pressure sensor 15 is commercially available. When the swing block 11 swings, one end of the swing block 11 contacts the pressure sensor 15 and a record is made. After the processor obtains the pressure, the counter inside the control device counts it to count the entire monitoring.

[0041] In some embodiments, the external discharge port is connected to an external discharge pipe 16, which extends outward from the cylinder 1 to prevent the soil at the bottom of the cylinder 1 from being washed away directly as it flows downward through the external discharge port, thus affecting the stability of the cylinder 1.

[0042] In some embodiments, the warning device includes a commercially available warning light and a buzzer, which are connected to a control device. A monitoring agency performs threshold classification to establish corresponding geological disaster levels. The levels are categorized as follows: a blue warning light indicates a possible minor geological disaster, with a generally low probability of occurrence and a small area / scale; a yellow warning light indicates a possible moderate geological disaster, with a relatively high probability of occurrence and a large area / scale; an orange warning light indicates a possible relatively serious geological disaster, with a high probability of occurrence and a large area / scale; and a red warning light indicates a possible extremely serious geological disaster, with a very high probability of occurrence and a large area / scale. This serves as a warning, visually alerting people near potential geological disaster risk areas to the current level of risk, facilitating timely evacuation or prevention measures, and enhancing the intuitiveness and timeliness of on-site geological disaster warnings.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. The above description is only a preferred embodiment of this utility model.
