を得ることが困難となる。 Conventionally, the Ministry of Transport's Marine Technology Research Institute system is known as a tidal current tank.As shown in FIG. This is a method to generate In this method, when the width of the water tank 50 is narrow, the flow inside the water tank is relatively uniform, but when the width is wide, the circulating water flow is concentrated on the outside (the right side of the water tank 50 in the figure) due to the centering force, resulting in a uniform flow. It becomes difficult to obtain.
この考案はこのような事情に鑑みて創案された
もので、その目的は水槽幅が比較的広い場合にも
均一な流れを得ることのできる潮流水槽を提供す

均一な流れが得られるようにしたものである。 The tidal flow tank according to this invention forms a deceleration tank with a deep water depth over the entire width of the tank inlet side, and a plurality of tidal current generating devices are installed in parallel in the tank at right angles to the water flow direction after the deceleration tank. It is installed submerged in water, and first, by decelerating the circulating water flow in a deceleration tank, uniform suction conditions are created for each tidal current generator, and then the tidal current generator generates a tidal current. Even if the flow is uniform, it is possible to obtain a uniform flow over its entire width.
以下この考案を図示する一実施例に基づいて説

１、循環水路２、減速水槽３および潮流発生装置
４から構成されている。 This invention will be explained below based on an illustrated embodiment. As shown in FIG. 2, the tidal flow tank is composed of a wide water tank 1, a circulation channel 2, a deceleration tank 3, and a tidal flow generator 4.
潮流発生装置４は幅広水槽１の入口側に、減速
水槽のあとに続けて水流方向と直角をなして並列
に複数個水没させて設置されている。 A plurality of tidal current generators 4 are installed on the entrance side of the wide water tank 1, following the deceleration tank, and submerged in parallel in a direction perpendicular to the water flow direction.
また、減速水槽３は水槽の全幅にわたつて水深
が深くされ循環された水流の流速を減じるように
されている。 Further, the deceleration water tank 3 is designed to have a deep water depth over the entire width of the tank to reduce the flow velocity of the circulated water flow.
このような構成であれば潮流発生装置４が複数
配設されかつ循環水流が減速水槽３で減速され均
一な吸込条件で潮流発生装置に吸込まれるため、
水槽１内の流速は均一となる。また、各潮流発生

とすることができる。 With such a configuration, a plurality of tidal current generating devices 4 are provided, and the circulating water flow is decelerated by the deceleration water tank 3 and sucked into the tidal current generating device under uniform suction conditions.
The flow velocity in the water tank 1 becomes uniform. Further, by adjusting the discharge amount of each tidal current generating device 4, it is possible to make the discharge amount more uniform.
次に潮流発生装置４は第３図に示すように、下
部にインペラ５、上部に電動機等の駆動源６を有
し、インペラ５はケーシング７内に、駆動源６は
水密ケース８内に収納されている。 Next, as shown in FIG. 3, the tidal current generating device 4 has an impeller 5 at the bottom and a drive source 6 such as an electric motor at the top. The impeller 5 is housed in a casing 7, and the drive source 6 is housed in a watertight case 8. has been done.
ケーシング７と水密ケース８はパイプ等の連結

１１で被覆され水密とされている。 The casing 7 and the watertight case 8 are connected and integrated by a connecting member 9 such as a pipe. The drive source 6 and the impeller 5 are connected by a power transmission mechanism 10 such as a chain transmission or a belt transmission. This power transmission mechanism 10 is covered with a covering material 11 such as a hollow member to make it watertight.
潮流水槽の入口側には下部が開口された仕切壁
１２，１３が設けられ、図示右から順に減速水槽
３、潮流発生装置用ピツト１４、幅広水槽１が形

装置４が挿入される。 Partition walls 12 and 13 with open bottoms are provided on the entrance side of the tidal flow tank, and a deceleration tank 3, a pit 14 for a tidal current generator, and a wide tank 1 are formed in order from the right in the figure. The tidal current generating device 4 is inserted into.
なお、不切壁１３の下部には整流板１３ａが設
けられ流速の乱れを整流するようにされている。 Note that a rectifying plate 13a is provided at the lower part of the uncut wall 13 to rectify disturbances in flow velocity.
前述のとおりこの考案に係る潮流水槽は水槽入
