は困る場合が多い。《Conventional technology》 Conventionally, as a flood control measure, water was stored in dams,
Electric flood gates are installed that can be opened and closed to release water from the dam. Manually operated water gates are also installed in small rivers. In any case, these are not easy to install technically or economically, and especially in the latter case, their maintenance and management and the opening and closing of the water gates are not easy. however,
Facilities that require the control of water inflow can be found everywhere. For example, in small waterways such as irrigation water and drainage canal water, it is often a problem if the amount of water exceeds a certain amount.
《考案が解決しようとする課題》
このような場合には、あまりに多くの水が流れ
過ぎるのを防止するための開閉水門と、バイパス
が必要となることは、大きな河川等の場合と基本
的に異なることはない。《Problem that the invention aims to solve》 In such cases, the need for opening/closing sluice gates and bypasses to prevent too much water from flowing is basically the same as in the case of large rivers. Nothing is different.
しかしながら、このような場合に従来のような

ことを見出し、本考案に到達した。 As a result of extensive research in response to the above requests, the inventor of the present invention has developed a system for small-scale waterways that utilizes the buoyancy of the water to raise the door when the water rises, without causing the door to overturn. They discovered that it is possible to dam the water while at the same time allowing the water to flow by tilting the door as the amount of water decreases, leading to the development of the present invention.

する自動開閉扉によつて達成された。<Means for Solving the Problems> The above objectives of the present invention are to consist of a door body that rotates in the direction of water flow according to the water level of the waterway, and a rotation shaft, and a door below the rotation shaft. The automatic opening/closing door forms a drainage port between the lower part of the door body and the bottom surface of the waterway, and the center of gravity of the door body in the closed state is located above and upstream of the rotation axis, and the door This is achieved by an automatic opening/closing door characterized in that a portion of the main body above the rotation axis is made of a material and/or structure that can float on water.
以下本考案を実施例に従つて詳述する。 The present invention will be described in detail below with reference to examples.
第１図は本考案の自動開閉扉の第１実施例であ

流側にある。 In the figure, numeral 1 represents the main body of the automatic opening/closing door, and 2 represents the horizontal axis on which the automatic opening/closing door rotates.The solid line representing main body 1 is when the water level is low and the door is open, and the dotted line is when the water level has increased. Indicates that the door is closed. In this case, the center of gravity of the door body, at least when the door is closed, is above the rotation axis and on the upstream side of the waterway.
又、扉の軸より上の部分は水に浮くように、水
に浮く材質でつくられているか、又は水に沈む材
質を使用したとしても、中空構造として水に浮く
構造を有している。 Also, the part above the shaft of the door is made of a material that floats on water, or even if a material that sinks in water is used, it has a hollow structure that floats on water.

扉の回動を不必要に妨げないように、軸から下の

ましい。[Operation] When the amount of water flowing through the waterway is small, the door tilts upstream due to the relationship between the center of gravity of the door and the rotation axis, leaving the waterway open. Therefore, water mainly flows through the channel, and as a rule does not flow into the bypass.
In this case, it is preferable to provide a stopper or adjust the position of the rotation axis or the center of gravity to prevent it from falling over more than necessary. Since the part above the shaft floats on water, as the amount of water in the waterway increases, buoyancy acts, and the door rotates in the direction of water flow and is raised, reducing the amount of water flowing through the waterway and reducing the amount of water flowing through the bypass. increase As the water level increases further, the door finally stands upright to close off the waterway, allowing all water to flow through the bypass except for the leaking part.
In order not to unnecessarily impede the rotation of the door, it is preferable that the portion below the shaft be made of material and structure that does not float on water.

い。 Therefore, the automatic opening/closing door of the present invention can be made integrally of the same material, or separately made above and below the shaft and then joined together. in this case,
By changing the overall shape of the door, it is possible to set the amount of water required to completely close the door, or to keep the amount of water flowing downstream from the door almost constant when the door is closed. . The width of the waterway may be made wider or narrower in the area where the door of the present invention is provided, as necessary, such as to prevent the door from falling or tilting toward the downstream side. Furthermore, a guide groove may be provided along at least one wall of the drainage channel in order to facilitate and ensure opening and closing of the door.

る。 In order to reduce water leakage when the waterway is closed, steps or protrusions may be provided on the side walls and bottom of the waterway. Conversely, the size and shape of the door can be designed so that a constant amount of water can flow when the door is in an upright position. In other words, the automatic opening/closing door in the present invention refers to a door that rotates according to the amount of water to control the amount of water, and is suitable not only for completely closing a waterway when the water rises, but also for continuing to release a certain amount of water. Also included in the concept of the automatic opening/closing door of the present invention.

うにすることができる。 FIG. 2 is a sectional view in the flow direction of a second embodiment of the present invention, and FIG. 3 is a plan view. In the figure, the solid line is the state when the water level is low and the door is open.
The dotted line indicates the state where the water volume has increased and the door is closed.
In the case of this embodiment, by enlarging the hemispherical portion at the top of the shaft, the waterway can be closed relatively quickly after the water rises. In this case as well, by appropriately setting the length and shape of the portion below the hemisphere, the width of the door, etc., it is possible to allow a constant amount of water to flow even when the water increases.
本考案の自動開閉扉を灌漑用水路に設けた場合
には、増水した水をそのまま水路に放流すること
なく、バイパスに流すことにより水田の冠水を防
ぐことができる。 When the automatic opening/closing door of the present invention is installed in an irrigation canal, flooding of rice fields can be prevented by allowing the increased water to flow through a bypass instead of being directly discharged into the canal.
又、小規模排水浄化設備の場合には、水量が多
くなると浄化能力が発揮できないのみならず、汚
泥等が流出され、かえつて汚染源となることもあ

ある。 In addition, in the case of small-scale wastewater purification equipment, if the amount of water increases, not only will the purification ability not be achieved, but sludge and other substances may flow out and become a source of pollution, so the waterways of the wastewater purification equipment should be closed when the water rises. However, it is also effective when draining water using a bypass.

る。<<Effects of the invention>> As detailed above, according to the invention, an automatic opening/closing door can be installed in a small-scale waterway at extremely low cost and easily, thereby preventing the inflow of water more than necessary or in excess of the processing capacity. . In addition, the automatic opening/closing door of this invention is
Since it uses buoyancy that varies depending on the water level of the waterway, it not only does not require special maintenance, but also is convenient because it does not require much effort to open and close.
