 [0001] WEIGHING RAINGAUGE USING A PAIRED BARREL CAPABLE OF AUTOMATIC STORAGE AND EMPTYING OF WATER [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weight weighing apparatus capable of automatically storing and draining water, and more particularly, to a weight weighing apparatus using an automatic watering system capable of automatically draining water according to the weight of stored water, will be.

In general, a conduction type rain gauge is used as a standard equipment for observing precipitation. These standard conduction type rain gauges have limited resolution and have a problem of storm drainage associated with the crossing of tipping buckets in the case of strong rain. Compared to observations at the same place, the conductivity type rain gauge showed 10-30% less precipitation than the weight type rain gauge.

Therefore, we use a weigh type rain gauge to observe precipitation in places where precise observations are required or where mountains are difficult to approach. It is well known that the weight type rain gauge is superior to the conduction type rain gauge in terms of function. This is because it is more accurate to measure the weight of rainwater collected like a weight type rain gauge than to estimate the number of times that the conductivity type rain gauge reaches a certain volume. In addition, under a similar precipitation environment, the weight type rain gauge can attain a resolution of 10 times or more as compared with the conduction type rain gauge, which is advantageous in terms of automatic observation and remote adjustment.

However, in spite of the excellent performance mentioned above, the resolution of the weighing scale is similar to that of the conduction type weighing scale at the observation site, and is rather lower in practical terms. The main reason is that no method has been developed to drain the rainwater properly. Secondly, the price of the load cell (load sensor) also makes it difficult to supply the weight weighing system. Siphon drainage of existing weighing instruments requires at least 5-10 seconds, albeit fluid. In recent years, the weight of a load cell is measured while collecting rainwater continuously for 3 months or 1 year during the observation period. That is, an accumulation type weight raising meter which does not drain water for a certain period of time is generally used.

In order to overcome the problems of the integrated type and siphon type weight type rain gauge as described above, modern commercial rain gauge uses a high performance load cell and adopts a once-a-year manual drain method in consideration of climatological precipitation. Belfort Instrument in the United States, OTT in Germany, and Geonor in Norway. The absence of a reasonable drainage method is the main reason that the weighbridge has a volume and weight of about two to three times the typical conduction type. The relatively large scale causes many restrictions on the use of the weighing scale.

In the case of recently commercialized weight type rain gauges, a large water tank has been adopted to continuously measure strong precipitation over a long period of time, to shorten the drainage time, or to remove it from the source. Large - capacity water tank can observe continuous precipitation for a certain time, but it leads to increase of fatigue of load cell and reduction of resolution of rainfall observation according to limit capacity of rain gauge. The limitation of the utilization of such a load cell results in the difficulty in installation and operation of the weight type rain gauge and the increase of the production cost.

FIG. 2 is a perspective view showing the inside of the heavy weighing instrument of FIG. 1, and FIG. 3 is an example of a pair of weights of the heavy weighing instrument of FIG. Fig. 4 is a perspective view showing the inside of the paired water tank of Fig. 3, and Figs. 5A and 5B are perspective views showing another example of the paired water tank of Fig.

1 and 2, the heavy weighing scale 1 according to the present embodiment includes a water receiver 90 formed at an upper portion thereof, and an apparatus such as a water tank capable of storing the precipitation water 10 can be mounted A load cell 100 installed in the body 95, a load cell 150, a rotation driving unit 200, and a controller (not shown).

The water receiver 90 is formed in a funnel shape having a lower diameter than that of the upper portion. The water collector 90 collects and flows the water into the double water tank 100. Although not shown, Alternatively, a detachable foreign matter prevention net can be formed to prevent foreign matter mixed with the eyes.

The double water tank 100 may have a columnar shape, for example, as shown in FIGS. 3 and 4, and may have a rectangular columnar structure as shown in FIGS. 5A and 5B. have.

The double water tank (100) may have a heat insulating material in order to prevent a measurement error due to the temperature of the outside air. Particularly, it is preferable to use a resin material having a low heat transfer rate rather than a metal material which can easily transfer heat. This is to prevent as much as possible the occurrence of errors in the measurement of precipitation by evaporation of the rainwater stored in the double water tank 100 when the summer temperature is high.

3, the dual water tank 100 is divided into a first water tank 110 and a second water tank 120 so as to divide the inside of the double water tank 100 from the upper surface of the double water tank 100, And a partition plate 130 attached to the partition plate 130 so as to extend toward the bottom surface.

Thus, the dual water tank 100 has a dual water tank structure including the first water tank 110 and the second water tank 120.

A first inlet 111 and a second inlet 121 are provided at upper and lower portions of the dual water tank 100, respectively. That is, the first water inlet 110 is provided in the first water tank 110, and the second water inlet 121 is formed in the second water tank 120.

The rainwater drained from the water injector 90 into the double water tank 100 passes through the first inlet 111 or the second inlet 121 and flows into the first water tank 110 or the second water tank 120 And then the weight is measured by a load cell 150 measuring the weight at the bottom of the first water tank 110 or the second water tank 120.

The load cell 150 is a typical load cell.

When the rain water is stored in the first water tank 110 or the second water tank 120, the detection weight of the load cell 150 gradually increases. When the predetermined water level is stored in the first water tank 110 or the second water tank 120, the center of gravity of the water tank 110 is raised, and the center of gravity of the water tank 110 is positioned on the upper part of the water tank 100 So that the double water tank 100 is rotated by gravity.

The control unit (not shown) receives the measured weight from the load cell 150 in the twin water tank 100. The control unit may calculate the measured weight as the height of the precipitation, and transmit the calculated result to the weather station, the weather information provider, and the like through a communication unit (not shown).

The control unit may process the measured values of the weight of the first water tank 110 or the second water tank 121 at regular intervals to store and process the data in real time, Can be transmitted.

Further, the control unit rotates the double water tank 100 according to the weight detection result of the double water tank 100 to selectively position the first inlet 111 or the second inlet 112 at the lower portion, It is possible to drain the precipitation water stored in the double water tank 100.

The rotation driving unit 200 rotates the double water tank 100 and includes a support table 210, a first rotation axis part 221, a second rotation axis part 222, and a support plate 230.

The supporter 210 is located on the outer side of both sides of the double water tank 100, and a hinge (not shown) is installed on the upper side.

The first and second rotary shafts 221 and 222 are made of a metal material and welded to the outer surface of the pair of water wash basins 100 as a pair of rotating shafts. One end of each of the first and second rotary shafts 221 and 222 is fixed to the outer surface of the double water tank 100 and the other end is rotatably coupled to the hinge. The first and second rotary shafts 221 and 222 may rotate together with the rotation of the pair of water wash basins 100 but the support table 210 is fixed to the support plate 230 without rotating.

FIG. 6 is a perspective view showing a state in which first and second side groups are attached to both side surfaces of the paired water tank of FIG. 3, and FIG. 7 is a view showing the first or second side tank of FIG.

The weighing scale 1 according to the present embodiment includes a first auxiliary tank 310 and a second auxiliary tank 320 which are detachably attached to both sides of the double water tank 100, ).

The first and second auxiliary reservoirs 310 and 320 may be used to minimize the amount of precipitation of precipitation when collecting a large amount of precipitation.

The first and second auxiliary tanks 310 and 320 are installed in a vertically reversed form and are provided with first and second inlet ports 311 and 321 for collecting the precipitation, respectively.

Thus, while the first water tank 110 stores the precipitation through the first inlet 111, the first side tank 310 stores the precipitation through the first inlet 311.

The first water tank 110 and the first water tank 310 drain the stored water and the second water tank 120 is connected to the second inlet 121, and the second auxiliary tank 320 stores the precipitation through the second inlet 321. [0064]

Furthermore, when precipitation is stored in the second water tank 120 and the second water tank 320 so that the water tank 100 rotates again, the second water tank 120 and the second water tank 320 Is drained, and precipitation is stored in the first water tank (110) and the first side water tank (310).

If the leaves or foreign matter that are caught by the filtering net are left for a long period of time, It is desirable to clean it.

8A to 8C, when the rain water 10 is generated, the rain water 10 is supplied to the water collecting unit (not shown) The load cell 150 formed in the lower part of the first water tank 110 (the lower side of the receiving plate 230) is collected in the first water tank 110 through the first inlet 111, The weight of the rainwater transmitted to the first water tank 110 is measured.

Meanwhile, the load cell 150 transmits the weight of the measured precipitation to the control unit, and the control unit calculates the measured weight as the height of the precipitation and transmits the calculated result to the weather station, weather information provider, do.

As the precipitation 10 is stored in the first water tank 110, the detection weight of the load cell 150 gradually increases. As a result, the center of gravity of the double water tank 100 is raised and the center of gravity of the water tank 100 is positioned above the double water tank 100. As a result, the double water tank 100 is rotated do.

In this case, the double water tank 100 rotates through the first and second rotary shafts 221 and 222 provided at the center, and the rainwater stored in the first water tank 110 serves to transmit power .

8C, when the first inlet 111 formed in the first tank 110 is formed at a position corresponding to the second inlet 121, . In this case, the turning radius is 180 degrees, and the double water tank 100 is rotated in half, and the rainwater stored in the first water tank 110 by gravity is lowered and drained through the first inlet 11 .

In this case, the rainwater stored in the first water tank 110 is drained, and the second water tank 120 stores the precipitation water 10 through the second inlet 121.

Therefore, the weight gauges 1 according to the present embodiment form a pair of water tanks 100 including the first and second water tanks 110 and 120, thereby discharging the rain water filled in the water gutters 100 And at the same time can store the precipitation inside.

This completes the half-turn process of the double water tank 100, and the process of draining the water stored in the second water tank 320 thereafter can be performed by repeating the above-described process.

According to the present embodiments, the dual water tank 100 including the first and second water tanks 100 and 120 is constructed so that drainage can be performed while the precipitation water is stored, thereby eliminating the observation limit value of the existing weight water meter A heavy rain gauge can be produced which can be continuously observed in the same manner as a conduction type while being highly accurate.

In addition, it is possible to downsize the volume and weight to one third of the weight woofers currently in commercial use, and the compact weight woofers can be easily installed and managed and the production cost is reduced.
