Description

Precipitation system, precipitation collection device and precipitation meter using the same {Pad heater, Water collecting funnel and Device for measuring amount of precipitation using the pad heater}

The present invention relates to an apparatus for measuring precipitation, and more particularly, to a precipitation meter, a heating device for precipitation meter and a catchment container for precipitation meter used in a system for preventing natural disasters such as landslides in mountainous terrain.

When rainfall falls on slopes made of natural land or soil, soil and water flow down the slope to the lower part of the slope under the influence of rainfall in the topsoil layer. As a result, soil erosion occurs at the top or the middle of the slope, and the soil shifted from the top is deposited in a relatively low altitude and a gentle slope.

Soil erosion and sedimentation are the most basic causes of natural topographical changes, and severe erosion can lead to landslides or slope collapse. In addition, when the soil lost from the slope meets small rivers and the like, it moves downstream. In this process, some of the soil is deposited at the bottom of the river to increase the height of the riverbed. Increasing riverbeds ultimately decreases the channel's access, which may be a potential source of flooding.

One of the important factors in this movement of soil is rainfall and snowfall. Therefore, it is very important to identify the relationship between the amount of soil shift and rainfall or rainfall. Therefore, it is common to install a precipitation meter in a landslide or natural mountain area. Of course, precipitation can be measured using information from the Korea Meteorological Administration. However, in the case of high altitude mountains, it is preferable to install a precipitation meter directly in the mountain areas because the difference in precipitation is very large.

3 to 6, the precipitation meter 100 according to the preferred embodiment of the present invention includes a measuring body 50, a collecting container 60, and a heating device 90.

Precipitation meter of the present invention, including a tipping bucket method and a weighing method, it is possible to employ any method for measuring precipitation by collecting rain or snow. Hereinafter, a tipping bucket type precipitation system will be described as an example.

Precipitation meter 100 according to the present embodiment is provided with a cylindrical casing 10, the collecting container 60 is accommodated in the cylindrical casing 10, the measuring body 50 is disposed in the lower portion of the collecting container 60 do.

The measuring body 50 is provided with a base member 30 in the lower portion, the tipping bucket 20 is installed on the base member (30). Metering tanks 21 and 22 are formed in the tipping bucket 20 in a symmetrical manner so as to temporarily accommodate the water discharged from the collecting container 60 to be described later. In addition, the tipping bucket 20 has a pivoting point 23 formed between the right and left sides of the fixed water tanks 21 and 22 so that the tipping bucket 20 is rotated based on the pivoting point 23.

When a predetermined amount of water is filled in the fixed-quantity tanks 21 and 22 on the left and right sides of the tipping bucket 20, the tipping bucket 20 is rotated by weight to drop the water in the fixed-quantity tanks 21 and 22 downward. The position is restored to the equilibrium position again.

In addition, drainage tanks 30 are provided below the left and right fixed water tanks 21 and 22 of the tipping bucket 20 to guide and discharge the water dropped from the fixed water tanks 21 and 22 to the outside, or the base member ( 40) Guide the water to the lower tank (not shown).

On the other hand, the tipping bucket 20 is provided with a sensor unit 45 consisting of a magnet body and a reed switch, when the magnet body is rotated to detect the number of times the reed switch is rotated. The tipping bucket 20 is rotated to detect the number of times the water of the fixed water tanks 21 and 22 is discharged to the outside to calculate precipitation.

In addition to the configuration of the method described above, the measurement body 50 for measuring precipitation may be configured in various forms such as a weight measurement method, and the measurement body 50 of such various forms is well known and thus will not be described in further detail. do.

The water collecting container 60 disposed on the upper portion of the measuring body 50 has a water collecting port 61 and a water collecting pipe 62 in the form of the upper and lower openings 63 and 64, respectively. The catching hole 61 is formed to have a diameter of the lower part gradually in a funnel shape, and the collecting pipe 62 is formed to extend downward from the lower side of the collecting hole 61 in a hollow shape.

Rain or snow is collected in the collecting container 60, and the snow is discharged downward while the snow is melted, and rainwater is directly discharged. However, when rain or snow freezes in the sump container 60 under the condition where the temperature falls below zero, water is not discharged to the lower part, which makes it difficult to measure precipitation.

Thus, in the present invention, it is provided with a precipitation device for heating device 90 to heat the water collecting container (60).

Precipitation heating device 90 has at least one heating pad 70, the heating pad 70 is attached to the inner or outer surface of the water collecting container (60). In the present embodiment, three heating pads 70 are provided to heat almost the entire area of the collecting container 60, and are attached to the inner surface of the collecting container 60.

The heating pad 70 includes heating elements 71 that are generated by current and pad members 72 and 73 that are attached to each other with the heating element 71 therebetween. The heating wire 71 is a heating tool that uses a point generated by a resistance when a current flows, and is disposed in a zigzag form between the pad members 72 and 73. However, the portion where the heating wire 71 is bent in the zigzag form the upper and lower portions of the pad members 72 and 73, so that the heating wire 71 is disposed long along the vertical direction of the pad members 72 and 73. .

Since snow accumulated in the collecting container 60 is melted along the heating wire 71, when the heating wire 71 is disposed long in the vertical direction, the snow melted water forms a waterway that can be naturally discharged from the upper side to the lower side. For example, unlike the present embodiment, when the heating wire is disposed in the transverse direction, waterways are formed along the transverse direction, so that snow melted water is not easily discharged as compared with the case in which the waterways are formed in the longitudinal direction.

In addition, the pad members (72, 73) is formed in a shape of the upper portion is wider and the lower portion so as to correspond to the shape of the collection container (60). In addition, the pad members 72 and 73 are formed in a thin film form using a flexible material so as to be in close contact with the inner surface or the outer surface of the water collecting container 60 having a curved surface.

In this embodiment, the pad member 73 disposed close to the collection container 60 uses a vinyl material, and the pad member 72 which is in direct contact with rain or snow uses an aluminum material.

The different materials of the two pad members 72 and 73 are to be used to melt the snow by minimizing the release of heat generated from the heating wire 71 to the outside. That is, if the thermal conductivity of the pad member 72 is relatively close to the eye or rain among the two pad members 72 and 73, the thermal conductivity of the pad member is relatively farther than the thermal conductivity. This is because more can be delivered to the collected snow in the container 60.

As in the present embodiment, when the heating pad 70 is attached to the inner surface of the collecting container 60, the pad member 73 which is in direct contact with the inner surface of the collecting container 60 is relatively to the part where the eyes are collected. Since it is disposed far away, the thermal conductivity is made of a vinyl material smaller than aluminum, and the pad member 72 in direct contact with the eye uses aluminum larger than vinyl.

And in the present invention, the heating pad 70 is detachably coupled to the water collecting container (60). This is because the heating pad 70 is advantageous in that it is detachable without being fixed to the water collecting container 60. In other words, the period of sub-zero temperatures during the year in Korea is limited to winter. This is because it is advantageous to store the temperature without using the heating pad 70 in the summer, etc., so that the heating pad is detachable.

In addition, it was difficult to measure the precipitation when the snow froze in the water collection container except for the heater buried in the existing precipitation meter, using the heating device 70 for the precipitation meter according to the present invention. It was possible to attach it separately to the collecting container 60 so that precipitation measurement was possible even in winter.

In addition, in the structure that can replace the collection vessel in the existing precipitation meter, the collection vessel (60) with a heating device for precipitation meter is replaced with the existing collection vessel to enable the measurement of precipitation even in winter.

 In this embodiment, the Velcro member is adopted to detach the heating pad 70 from the water collecting container 60. That is, the first Velcro member 78 is attached to the collecting container 60, and the second Velcro member 79 is attached to the heating pad 70, so that the first Velcro member 78 and the second Velcro member 79 are attached. The heating pad 70 is detachably coupled to the water collecting container 60 by the coupling between the two pads.

Of course, the method of detaching the heating pad 70 to the water collecting container 60 may be employed in various ways. In this embodiment, the Velcro member is used in consideration of the convenience and economical efficiency of the precipitation device heating device 90. do.

 On the other hand, in the present embodiment, a plurality of heating pads 70 are arranged, the heating wire 71 is formed integrally. That is, one heating wire 71 extends across the plurality of heating pads 70 and is connected to a power source. In addition, the heating wire 71 extends to the collecting pipe 62 of the collecting container 60. That is, since the snow or rain can freeze even in the water collecting pipe 62 disposed below the water collecting port 61, the heating wire 71 extending in a coil shape is also in close contact with the inner surface of the water collecting pipe 62 to close the water collecting pipe 62. Heat. The insulating wire 71 disposed between the heating pads 70 is wrapped by the coating so as not to contact with water.

In addition, in this embodiment, a temperature sensor and a precipitation sensor are provided. The temperature sensor is a digital thermometer, and the precipitation sensor detects snow or rain, and a moisture sensor for measuring the presence of water may be employed. The heating wire 71 is in a state of being connected to a power source, and does not supply power to the heating wire 71 from the power source when the temperature measured by the temperature sensor as well as when there is no snow or rain.

When snow or rain is sensed by the moisture sensor and the temperature is sensed below zero, power is supplied to the heating wire 71.

Hereinafter, with reference to Figure 7, the operation of the precipitation meter 100 made of the above configuration will be described. FIG. 7 is a schematic operation flowchart of the precipitation meter shown in FIG. 3.

Referring to FIG. 7, when snowfall and rainfall are sensed and the temperature is measured below zero, the collector vessel 60 is heated by supplying power to the heating wire 71 from a power source. The heating temperature is about 5 degrees Celsius or less. This is because 5 ° C can sufficiently prevent freezing in the collecting container 60. If the temperature rises too much, the durability of the heating wire 71 may be lowered. Therefore, when the temperature of the heating wire 71 is measured using a separate temperature sensor, the power supply is cut off when the temperature exceeds the set temperature, for example, 5 ° C. When the temperature of 71 decreases, it operates by supplying power.

Temperature sensor and precipitation sensor continuously measure whether snow and rain persist and temperature to detect whether water in the container can freeze, and the power supply is based on the signals received from the above sensors. Supply.

So far, the precipitation apparatus 90 is described and illustrated as being attached to the inner surface of the collecting container 60, but is not necessarily limited thereto, and may be attached to the outer surface of the collecting container as shown in FIG. 9.

That is, when the heating pad 70 is attached to the inner surface of the water collecting container 60, there is an advantage in the heat transfer, but even if attached to the outer surface is possible to transfer the heat enough to melt the snow and the heating pad is covered by the water collecting container snow or rain Because it is not directly exposed to the product, the service life may be increased. In addition, there is an advantage that it is easier to attach to the outer surface of the collecting container 60 than to the inner surface.

When the heating pad 70 is attached to the outer surface of the water collecting container 60 as described above, the pad member 73 directly contacting the water collecting container 60 is disposed relatively close to the eyes collected inside the water collecting container. The material of the member 73 is made of aluminum, and the material of the pad member 72 disposed outside is made of vinyl.

In the embodiment 200 illustrated in FIG. 9, all other configurations are the same except that the heating wire 71 surrounding the heating pad and the collecting pipe 62 is attached to the outer circumferential surfaces of the collecting hole 61 and the collecting pipe 62, respectively. A separate description will be omitted.

As described above, in the precipitation meter (100,200) equipped with the heating device 90 for the precipitation meter according to the present invention, it is possible to reliably measure precipitation regardless of temperature by preventing freezing in the collecting container even in winter.

In addition, since the precipitation device heating apparatus 90 according to the present embodiment can be easily coupled to the existing precipitation system, the subzero condition using the existing precipitation meter without purchasing a separate precipitation meter in which the heater is embedded. Precipitation can also be measured at.

In addition, the present precipitation system heating device 90 can be manufactured very economically by using a Velcro member, and there is an advantage that it is easy to use because it is easily attached and detached to the water collecting container.
