Description

Technical Field

[0001] The utility model relates to the field of landslide monitoring, and in particular to a self-powered funnel-shaped rain gauge for landslide monitoring. Background Art

[0002] Landslide refers to the phenomenon that the rock and soil on a slope of a certain slope slides down the slope under the influence of various factors and eventually under the action of gravity. Landslide monitoring requires comprehensive consideration of geological, hydrological, topographical, human and earthquake factors. By monitoring and analyzing the changes in these factors, timely warnings and corresponding prevention and control measures can be taken to reduce the occurrence of landslide disasters. Rainfall is a major factor leading to landslides. Long-term and large-scale rainfall causes a sharp increase in soil moisture content and increased instability. According to landslide monitoring theory, rainfall will accelerate the isokinetic deformation stage of the slope. The landslide body will continue to deform at this stage, and finally accelerate the deformation until the landslide occurs. From the perspective of monitoring theory, the measurement of rainfall is extremely important for preventing landslides.

The utility model improves the objectivity of the same rain gauge counting by using the counting function of the three-level pressure sensor connected to the microprocessor, reduces the error of the statistical data; and improves the utilization rate of energy by using the solar wall, ensuring that the operation energy of the entire device is sufficient.

[0004] However, the above-mentioned automatic rainfall monitoring device uses a battery to power the measured data for transmission, reception and storage. Most sensors require external power supply to work properly, which means that additional power supply is required for long-term use in the field, and the cost of subsequent maintenance will also increase. Utility Model Content

[0005] The utility model provides a self-powered funnel-shaped rain gauge for landslide monitoring, which solves the problem in the prior art that monitoring work requires external power supply to work normally, thereby increasing the cost of subsequent maintenance.

[0007] Preferably, the outer side of the rotating member is provided with a plurality of spiral layers in an annular shape, and each spiral layer is also folded from the same material and adhered to the outer sector surface of the rotating member.

[0008] Preferably, both ends of the wire are electrically fused to the small bulb and the copper electrode respectively.

[0009] Preferably, a hole is opened in the upper part of the base for the support rod to be screwed in, and a square groove is opened in a ring shape around the outer side of the base.

[0013] Preferably, the copper electrodes of the inner sector surface of the rotating member and the outer sector surface of the base are in contact with each other.

[0014] The beneficial effects of the utility model are:

[0015] The utility model provides a rotating part on the top of the base. When it rains, rainwater will fall into the top of the rain collecting funnel and fall into the top of the rotating part through the groove inside the supporting rod. At this time, water flows through the internal groove of the supporting rod to form a water flow and drips on the rotating part. Since there is a spiral layer on the rotating part, and all of them are lightweight and waterproof materials, the rotating part can be driven to rotate. The polyimide inside the adhered rotating part will rotate together and rub the copper electrode fitted with it. According to the relevant theory of friction nanogenerators, electric charges will flow between the two materials at this time, and current will be generated and conducted to the small light bulb through the wire. When rainfall drives the rotation friction to generate electricity, the power generation of the small light bulb can intuitively display the rainfall. Through this design, rainfall monitoring can be completed without external power supply, thereby greatly reducing the later maintenance cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See also Figure 2 There are four spiral layers distributed in a ring shape on the outside of the rotating part 2, and each spiral layer is also folded from the same material and adhered to the fan-shaped surface on the outside of the rotating part 2.

Through this design, the small bulb 9 can be powered and lit. The wire 8 can pass through the reserved slot inside the support rod 7 to complete the connection between the copper electrode 4 and the small bulb 9.

[0029] See also Figure 1 - Figure 4 The upper part of the base 6 has a hole for the support rod 7 to be screwed in, and the outer side of the base 6 is provided with a square groove in a ring shape.
