提供せんとするものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a water level simulating device for a reservoir or the like, and particularly to provide a simulating device capable of simulating a water level in an adjacent area.

自動水位調節装置として使用することができる。Controls are carried out on adjacent properties using televisions and other equipment without direct on-site observation by managers. However, even with the use of televisions, it is difficult to accurately monitor changes in water level from time to time due to errors caused by waves and the need to have a professional watcher in front of the television at all times. It is quite difficult. Furthermore, there has been no suitable automatic alarm system that accurately responds to water level changes, especially water level rises. The water level simulator of this invention accurately reflects changes in the water level of a reservoir, etc. in an adjacent area, and is connected to the operating mechanism of an alarm device or water gate opening/closing device, and is activated in accordance with changes in the water level of the simulator. By doing so, it can be used as an automatic water level warning device or an automatic water level adjustment device.

る。That is, the water level simulating device of the present invention is capable of recognizing the amount of fluctuation in the water level in a reservoir in an adjacent area either as a numerical value as it is, or after being enlarged or reduced. An embodiment of the present invention will be described below based on the drawings.

同じ水位に満たされている。FIG. 1 is an explanatory diagram of the operation of the present invention, in which water from the reservoir 1 flows through the communication hole 3 into the container 2, which is installed in the reservoir 1 and has a small diameter communication hole 3 formed in the side wall or bottom. filled to the same water level.

Float 4 (larger than the drainage weight below) is floating,
A rope 5 is fixed to its upper surface. A drainage weight 8 is attached to the float 4 at the adjacent land via this rope 5.
(more specific weight than water) is connected. 6, T is a guide roller supporting the rope 5;

に対し、排水重錘８の上下に応じて有底筒状体９内の水
位は、排水重錘８が上昇すればその上昇分の容積に等し
い容積分の高さｈだけ下降し、排水重錘８が下降すれば
その下降分の容積に等しい容積分の高さだけ上昇する。The drainage weight 8 is suspended in a bottomed cylindrical body 9 installed in an adjacent area such as inside a reservoir management building, and the lower part is immersed in clear water 10 filled in this bottomed cylindrical body 9. Immersed.
FIG. 2 is an enlarged side view of the bottomed cylindrical body 9. This bottomed cylindrical body 9 is filled with clear water 10, and a drainage weight 8 is immersed in the water. This drainage weight 8 moves in the bottomed cylindrical body 9 in response to the vertical movement of the flow volume 4 and in the opposite direction over the same distance. That is, if the float goes up, the drainage weight 8 goes down by the same distance, and if the float goes down, the drainage weight 8 goes up by the same distance. On the other hand, depending on the vertical position of the drainage weight 8, the water level inside the bottomed cylindrical body 9 will fall by a height h equal to the volume of the rise when the drainage weight 8 rises, and When the weight 8 descends, it rises by a volume equivalent to the volume of the descent.
したがつて有底筒状体９内の水位は、貯水池１内の水位
に応じてフロート４が上昇し、このフロート４と連動す

せるというように、貯水池１内の水位と完全に比例する
。しかしながら有底筒状体９内の水位の変動は、有底筒
状体９の底面積に占める排水重錘８の底面積の比率にか
かつている。Therefore, the water level in the bottomed cylindrical body 9 is increased by the float 4 rising according to the water level in the reservoir 1, and the drainage weight 8 interlocking with this float 4 descending. It is completely proportional to the water level in the reservoir 1, as it raises the water level. However, fluctuations in the water level within the bottomed cylindrical body 9 depend on the ratio of the bottom area of the drainage weight 8 to the bottom area of the bottomed cylindrical body 9.

容積の変動量は次式で表わされる。１１１１／ 五工
要約すると次式のようになる。That is, when the bottom area of the bottomed cylindrical body 9 is A, and the bottom area of the drainage weight 8 is A/n, if the lifting or descending distance of the drainage weight 8 is H, the drainage weight 8 is in the water. The amount of variation in volume 2 is A/NXH, and the amount of variation in volume of the water surface portion in the bottomed cylindrical body 9 is expressed by the following equation. 1111/ Five steps To summarize, it is as follows.

動量（ＫＨ）の変数（ｋ）は次式のようなｊ関係を有し
ているのである。In other words, for a fluctuation rate 1 of the water level in the reservoir that is equal to the rising or falling distance of the drainage weight 8, the variable (k) of the water level fluctuation amount (KH) in the bottomed cylindrical body 9 has a j relationship as shown in the following equation. We have it.
（なおＡ＞Ａ／ｎであるからｎ〉１）
以上のことは排水重錘８が有底筒状体９の半分５の底面
積のとき、言いかえればｎ＝２のときは、ｋ−１となつ
て貯水池の水位と有底筒状体９内の水位とは完全に同一
距離だけ変化する。(Since A>A/n, n>1) The above means that when the drainage weight 8 has a bottom area of half 5 of the bottomed cylindrical body 9, in other words when n=2, k- 1, and the water level in the reservoir and the water level in the bottomed cylindrical body 9 change by exactly the same distance.

９の水位変動にあられれる。In this case, the transparent window 11 provided on the side wall of the bottomed cylindrical body 9 is provided with scales having the same interval. Next, when the drainage weight 8 has a bottom area of more than half of the four-bottomed cylindrical body 9, for example, n=1
．． 5 or when n=1.25, k=2 or k
= 4, the water level fluctuations in the reservoir are magnified and reflected in the water level fluctuations in the bottomed cylindrical body 9. Therefore, the intervals between the scales become wider, and the amount of variation can be read in more detail. Conversely, when the drainage weight 8 has a bottom area less than half of the bottomed cylindrical body 9,
For example, when N3 or n-4, k= or k=
I, the water level fluctuations in the reservoir are reduced and reflected in the water level fluctuations in the bottomed cylindrical body 9.

る。Therefore, large amounts of variation can be observed using a small-scale device. Note that 12 is a water level sensor such as a non-contact relay, which is suspended by a cord 13 on the bottomed cylindrical body 9, and is connected to an alarm and a gate opening/closing mechanism. When the water level rises and the water level sensor 12 is energized, the alarm and gate opening/closing device are activated. In the present invention, the container 2 installed in the reservoir 1 is a cylindrical tank made of iron or FRP with a communication hole 3 provided in the lower part of the side wall, or a tank with compartments partitioned into the reservoir 1 with a concrete wall or the like. However, there are also those in which communicating holes are formed.

へ行かずに遠隔地で、時々刻々と変化する水位を正確に
知ることができるようになつた。The drainage weight 8 attached to the other end of the wire rope 5 is made lighter than the float 4, but must have a higher specific gravity than the water in the bottomed cylindrical body 9. Since the water level simulating device of the present invention is configured as described above, it can be installed in reservoirs such as dams and canal power plants, or in rivers, and can be used to monitor constantly changing water levels in remote areas without going to dangerous water edges. It is now possible to accurately determine the water level.
