Description

【0001】
【発明の属する技術分野】
本発明は、水槽などの液面に、波を人工的に発生する造波用スネーク動作フラップおよびこれを用いた造波装置に関する。
【0002】
【従来の技術】
従来、3次元波を正確に発生する方法として、特公平6−70598号公報に示す造波装置が提案されている。同公報によれば、この造波装置は、水平方向に所定の間隔をもって並設され前後方向に進退する多数の受具と、これら受具のうち相互に隣接する2つの受具に連結され前後方向に揺動する多数の造波板とを備えている。これら造波板は、一方の連結部が前記受具の並列方向に摺動し、他方の連結部が上下方向に延在する軸線の回りに回動する造波板により構成されている。これら造波板のうち相互に隣接する2つの造波板の間隔は、フレキシブルシールプレートによって閉塞し、これらフレキシブルシールプレートは前記造波板に対して一方端部が固定され、他方端部が摺動自在に設けられていることが記載されている。
【0003】
【発明が解決しようとする課題】
しかしながら、特公平6−70598号公報においては、図7に示すように、それぞれの造波板81の前面部81Aが鉛直を保ちながら駆動装置83により前後に移動するピストン型運動を行うため、造波板81で排除される水粒子の速度(V)が、どの深さでも同一になってしまうという構造特性をもっている。この特性は、港湾分野等、波の波長に比べて水深の浅い水域での波、すなわち、水粒子の運動(V)がほぼ前後運動であり、しかも水深方向ではあまり運動振幅に差がないような波を発生するのに相応しいものである。しかし、この特性は、造船分野等、波の波長に比べて水深の深い水域での波、すなわち、水粒子の運動が楕円運動で水底に近づくほど、その楕円運動が小さくなるような波とは、かなり異なったものである。このような波は、従来、波の進行方向と水深方向だけを考える2次元波の造波においては、このような比較的水深の深い波の造波においては、水粒子の運動(Vb)に一致する度合いが高い造波板として、図8に示すような主型造波板91が使用されて来た。しかるに、図8に示すような造波板91を単純に並べて、3次元造波機として個別に動作させるときに、図9に示すように造波板91の前面91Aが静水面(S)と接する線を上から見ると、どうしても隣接する造波板同士が階段状(D)にならざるを得ないという特性を有しており、実際の波に合っていないという欠点を有している。
【0004】
本発明は、上記従来の問題点に着目し、深さ方向について主型運動を保ちつつ、波の幅方向については、より連続性を持ったスネーク動作が可能であり、実際の海洋に倣った3次元波の波を発生することができる造波用スネーク動作フラップおよびこれを用いた造波装置を提供することを目的としている。
【0005】
【課題を解決するための手段】
上記目的を達成するために、本発明に係る造波用スネーク動作フラップは、前後揺動可能に複数の造波板を配列し、隣接する前記造波板の間に形成された隙間を埋めるよう前記造波板に連結される連結ユニット板を有し、当該連結ユニット板は複数の扇型板を積層して形成するとともに扇子状に開閉できるように相互連結して形成し、前記扇型板の積層上下端の外側縁にヒンジを取付け隣接する前記造波板とスネーク運動可能に結合してなる構成を特徴としている。この場合において、前記連結ユニット板における扇型板は、各扇型板間の側縁に前記扇型板間の隙間を覆うプレートを取付け扇子状に開閉可能とすればよい。
【0006】
また、本発明に係る造波装置は、水槽の底部に枢着されて前後揺動可能複数の造波板と、隣接する前記造波板の間に形成された隙間を埋めるよう前記造波板にヒンジを介して積層上下端の外側縁を連結した複数の扇型板を扇子状に開閉可能とし連結ユニット板とからなるスネーク動作フラップを有し、当該スネーク動作フラップの造波板を前後に揺動させる複数のアクチュエータを備え、配列された前記アクチュエータの位相を順次変えて前記造波板を揺動させることにより前記スネーク動作フラップにスネーク動作を付与させる制御手段を備えたことを特徴とするものである。
【0007】
【発明の実施の形態】
以下に本発明に係る造波用スネーク動作フラップおよびこれを用いた造波装置の具体的実施の形態について図面を参照しつつ、詳細に説明する。
図1は実施形態に係る造波用スネーク動作フラップを用いた造波装置の全体構成斜視図である。同図において、造波用スネーク動作フラップ10が水槽12の1縁部に沿って据え付けられている。この造波用スネーク動作フラップ10は、ほぼ三角形形状の造波板14を横方向に一列に連続して一平面を構成するように配列されている。すなわち、三角形状の底辺が直線状に縦列するように水槽12の底部に配列され、個々の造波板14の底辺部を水槽12の底部とヒンジ結合させ、上端部が前後に揺動できるように取着されている。このような造波板14の各々には電動シリンダ16が連結され、各々独立して揺動運動ができるようになっている。電動シリンダ16は水槽12の躯体上部に据え付けられ、シリンダロッド18を造波板14の上端部に連結している。電動シリンダ16を駆動制御する手段としてのコントローラ20が設けられており、これは前記造波板14にスネーク運動を与えるように電動シリンダ16の位相をずらして運転させるようにしている。すなわち、シリンダロッド18の先端が正弦波の軌跡上にあるようにシリンダロッド18のストローク制御をなさしめるのである。
【0008】
ところで、上記造波板は、正面形状が三角形状とされ、底辺部を水槽12の底部にヒンジ結合されているため、隣接する造波板14同士の間には逆三角形状の隙間が生じる。この隙間は造波作用を発揮させる上で埋め込んでおく必要がある。本実施形態では、複数の造波板14を位相が異なるように前後に揺動させるため、造波板14間の隙間距離が変動する。このような稼働中における変動隙間が常に閉鎖されて、造波作用に支障を来さないように、扇子状に開閉動作される連結ユニット板22をもって前記隙間を埋めている。
【0009】
造波板14の間の隙間に装着される連結ユニット板22は、左右の造波板14に連結されるが、これは複数の扇型板24(24A、24B、………)を積層して形成するとともに扇子状に開閉できるように相互連結して形成し、積層上下端の扇型板24A、24Nを隣接造波板14、14に結合している。この具体的構成を図2〜図6に示す。
【0010】
図示のように、実施形態における連結ユニット板22は、一対の造波板14,14の間に装着されるが、図3に示しているように、長さが若干異なる複数の扇型板24を面スライド可能に相互連結して構成される。より具体的には、前記連結ユニット板22における各扇型板24は一方に長穴26を形成し、他方に当該長穴26に嵌入される連結ピン28を備えて相互連結されて扇子状に開閉可能とされているのである。図4は連結ユニット板22を閉じた状態を示し、図5は開いた状態を示している。積層されている最上面の扇型板24Aの外側縁にはヒンジ30Lを取付け、また、最下面の扇型板24Nの外側縁にも同様にヒンジ30Rを取付け(図4参照)、それぞれ左右の造波板14、14に連結するようにしている。図6は左右一対の造波板14,14が同一面上にある場合の平面図と(同図(1))、上端が最大離隔状態にある場合の平面図(同図(2))とを示している。図6(1)に示しているように、最小の隙間の場合には、連結ユニット板22は図4の状態となる。また、図6(2)に示しているように、最大隙間が形成されるように左右の造波板14,14が作動された場合には、図5(1)の状態の最大に広げられた状態となる。連結ユニット板22はヒンジ30L、30Rにて造波板14の側縁を中心とした回動が可能となっているので、図6(2)のように造波板14同士が最大離間したような場合であっても。連結ユニット板22は造波板14同士の間に通流隙間を形成することがない。扇型板24間の隙間からの通水が問題であれば、図5に示すように、各扇型板24の側縁にテフロン(登録商標)プレート32を取付け、隙間からの漏れをなくすように調整すればよい。
【0011】
造波装置は、図1に示すように、電動シリンダ16の全部一体の作動により、全部の造波板14が水槽の底部に対して一体で前後方向に揺動されるが、コントローラ20が各電動シリンダ16のストローク制御を行い、連結された造波板14に位相差が生じるように揺動させ、これにより上方から見た場合に、正弦波に沿った動きをなすように作動される。各造波板14の間には連結ユニット板22が介装されており、これは左右の造波板14の動きに応じて、図6(1)の最小離間位置と、同(2)に示す最大離間位置との形態を限度として扇子状の開閉動作をなす。これにより、上面から造波板14と連結ユニット板22からなる造波用スネーク動作フラップ10見た場合、スネーク運動をなすのである。これにより、全般の造波用スネーク動作フラップ10の作動により、図1、図8に示すような水底を起点とした造波板14の前後運動と、電動シリンダ16によるストローク制御による造波用スネーク動作フラップ10の上縁側のスネーク運動により、波の波長に比べて水深の深い水域での波、すなわち、水粒子の運動が楕円運動で水底に近づくほど、その楕円運動が小さくなるような波の速度が与えられ、また、このとき波は、図1に示すよう、造波用スネーク動作フラップ10の造波板14に対して傾斜した波の波長(Wa)を発生することができる。
【0012】
また、従来の階段状に形成された段差を設けた造波板に比較して、造波板14は段差がなく連続しているため段差エッジ部近傍に発生していたリングウエイブを防止でき、連続した波を発生することができる。
また、造波板14間には間隙を埋め扇子状の開閉運動をなす連結ユニット板22をを設けているため、水の浸入を防止することができるとともに、段差を少なくすることができ連続性を持った折れ線状に接続する造波板にすることができる。また、深さ方向について主型運動を保ちつつ、波の幅方向については、より連続性を持った折れ線状に接続する造波板を有し、実際の海洋に適した3次元波の波を発生することが行われる。
【0013】
造船分野など実験する波の波長に比べて、比較的水深の深い水槽実験においては、水粒子の運動に合致した主運動型の造波板が相応しいとされている。従来では、このために造波板の数を増して造波板の幅を極力狭くすることによって段差を少なくし滑らかな造波面を得ていた。これに比べて、本実施形態に係る造波用スネーク動作フラップおよびこれを用いた造波装置によれば、三角形状の造波板14を互いに揺動自在にしつつ、これらの隙間を埋める連結ユニット板22を連結している構成を採用しているため、フラップ10に接している静水に上下方向の水粒子の速度(V)を与え、この速度は主造波板および接続造波板の底面の近傍で小さく、液面に近づくにしたがって大きくなる主型運動となるので、3次元の方向性を持った波を、より正確に、かつ、経済的に連続した波を発生することができるとともに、段差エッジ部近傍に発生していたリングウエイブを有効に防止できるものとなる。
【0014】
【発明の効果】
以上説明したように、本発明によれば、水槽の底部に枢着されて前後揺動可能複数の造波板と、隣接する前記造波板の間に形成された隙間を埋めるよう前記造波板にヒンジを介して積層上下端の外側縁を連結した複数の扇型板を扇子状に開閉可能とし連結ユニット板とからなるスネーク動作フラップを有し、当該スネーク動作フラップの造波板を前後に揺動させる複数のアクチュエータを備え、配列された前記アクチュエータの位相を順次変えて前記造波板を揺動させることにより前記スネーク動作フラップにスネーク動作を付与させる制御手段を備えた構成としているので、深さ方向について主型運動を保ちつつ、波の幅方向については、より連続性を持ったスネーク動作が可能であり、実際の海洋に倣った3次元波の波を発生することができるという優れた効果が得られる。

BACKGROUND OF THE INVENTION
The present invention relates to a snake action flap for artificially generating waves on a liquid surface such as a water tank and a wave making apparatus using the same.
[0002]
[Prior art]
Conventionally, as a method for accurately generating a three-dimensional wave, a wave making device disclosed in Japanese Patent Publication No. 6-70598 has been proposed. According to the publication, this wave making device is connected to a large number of receivers arranged in parallel in the horizontal direction at predetermined intervals and advanced and retracted in the front-rear direction, and to two receivers adjacent to each other among these receivers. And a number of wave-making plates that swing in the direction. These wave-making plates are constituted by wave-making plates in which one connecting portion slides in the parallel direction of the support and the other connecting portion rotates around an axis extending in the vertical direction. The space between two wave plates adjacent to each other among these wave plates is closed by a flexible seal plate, and one end of the flexible seal plate is fixed to the wave plate and the other end is slid. It is described that it is provided movably.
[0003]
[Problems to be solved by the invention]
However, in Japanese Examined Patent Publication No. 6-70598, as shown in FIG. 7, the front surface portion 81 </ b> A of each wave-making plate 81 performs a piston-type motion that is moved back and forth by the drive device 83 while maintaining the vertical direction. It has a structural characteristic that the velocity (V) of water particles eliminated by the corrugated plate 81 is the same at any depth. This characteristic is that the wave in the water area where the water depth is shallower than the wave wavelength, such as the port field, that is, the motion (V) of the water particles is almost back-and-forth motion, and there is not much difference in motion amplitude in the depth direction. It is suitable for generating a strong wave. However, this characteristic is a wave in a deep water area compared to the wavelength of the wave, such as in the shipbuilding field, that is, a wave whose elliptical motion becomes smaller as the motion of water particles approaches the bottom of the water by elliptical motion. Is quite different. Conventionally, in the wave formation of a two-dimensional wave considering only the wave traveling direction and the water depth direction, such a wave is caused by the movement of water particles (Vb) in the wave formation of such a relatively deep wave. As a wave-making plate having a high degree of coincidence, a main-type wave-making plate 91 as shown in FIG. 8 has been used. However, when the wave-making plates 91 as shown in FIG. 8 are simply arranged and individually operated as a three-dimensional wave-making machine, the front surface 91A of the wave-making plate 91 and the hydrostatic surface (S) are shown in FIG. When the line in contact is viewed from above, the adjacent wave-making plates inevitably have a stepped shape (D), and there is a disadvantage that they do not match the actual wave.
[0004]
The present invention pays attention to the above-mentioned conventional problems, and while maintaining the main motion in the depth direction, the snake operation with more continuity is possible in the width direction of the wave, following the actual ocean. An object of the present invention is to provide a snake operation flap for wave generation capable of generating a three-dimensional wave and a wave making apparatus using the same.
[0005]
[Means for Solving the Problems]
To achieve the above object, snake operation flap Wave according to the present invention, by arranging a plurality of wave-plate swingably back and forth, said to fill the gap formed in said wave-making plates adjacent granulation A connecting unit plate connected to the corrugated plate, wherein the connecting unit plate is formed by stacking a plurality of fan-shaped plates and interconnecting the fan-shaped plates so as to be opened and closed; A configuration is characterized in that hinges are attached to the outer edges of the upper and lower ends and the adjacent wave-making plates are coupled so as to be capable of snake motion . In this case, the fan-shaped plate in the connecting unit plate may be attached to a side edge between the fan-shaped plates so as to be openable and closable by attaching a plate covering the gap between the fan-shaped plates .
[0006]
Further, wave-device according to the present invention, a plurality of wave-plate pivotable back and forth is pivotally mounted to the tank bottom, the wave-plate so as to fill the gap formed in said wave-making plates adjacent It has a snake action flap consisting of a connecting unit plate that can open and close in a fan shape a plurality of fan-shaped plates that connect the outer edges of the upper and lower layers through hinges, and the wave-making plate of the snake action flap comprising a plurality of actuators for swinging, characterized by comprising a control unit for applying snake operation to the snake operation flaps by swinging sequentially changed in the wave-plate the phase of arrayed said actuator Is.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
A specific embodiment of a snake action flap for wave making and a wave making apparatus using the same according to the present invention will be described below in detail with reference to the drawings.
FIG. 1 is a perspective view of the overall configuration of a wave making device using a wave making snake action flap according to an embodiment. In the figure, a snake action flap 10 for wave making is installed along one edge of a water tank 12. The wave-forming snake action flaps 10 are arranged so that a substantially triangular wave-making plate 14 is continuously arranged in a row in a row to form a plane. That is, the bottoms of the water tanks 12 are arranged so that the bottoms of the triangles are aligned in a straight line, and the bottoms of the individual wave-making plates 14 are hinged to the bottoms of the water tanks 12 so that the tops can swing back and forth. Has been attached to. An electric cylinder 16 is connected to each of the wave forming plates 14 so as to be able to swing independently. The electric cylinder 16 is installed at the upper part of the housing of the water tank 12, and connects the cylinder rod 18 to the upper end of the wave making plate 14. A controller 20 is provided as a means for driving and controlling the electric cylinder 16, which is operated by shifting the phase of the electric cylinder 16 so as to give a snake motion to the wave making plate 14. That is, the stroke control of the cylinder rod 18 is performed so that the tip of the cylinder rod 18 is on the locus of the sine wave.
[0008]
By the way, since the front shape of the wave plate is triangular, and the bottom side is hinged to the bottom of the water tank 12, an inverted triangular gap is generated between adjacent wave plates 14. This gap needs to be embedded in order to exert the wave forming action. In this embodiment, since the plurality of wave forming plates 14 are swung back and forth so that the phases are different, the gap distance between the wave forming plates 14 varies. The fluctuation gap during operation is always closed, and the gap is filled with a connecting unit plate 22 that is opened and closed in a fan shape so as not to hinder the wave forming action.
[0009]
The connecting unit plate 22 mounted in the gap between the wave forming plates 14 is connected to the left and right wave forming plates 14, which are formed by stacking a plurality of fan-shaped plates 24 (24 A, 24 B,...). The upper and lower fan-shaped plates 24A and 24N are coupled to the adjacent wave-making plates 14 and 14 so as to be opened and closed in a fan shape. This specific configuration is shown in FIGS.
[0010]
As shown in the figure, the connecting unit plate 22 in the embodiment is mounted between a pair of wave-making plates 14, 14, but as shown in FIG. 3, a plurality of fan-shaped plates 24 having slightly different lengths. Are connected to each other so as to be slidable. More specifically, each of the fan-shaped plates 24 in the connection unit plate 22 has a long hole 26 formed on one side and a connection pin 28 fitted into the long hole 26 on the other side. It can be opened and closed. 4 shows a state in which the connecting unit plate 22 is closed, and FIG. 5 shows an open state. A hinge 30L is attached to the outer edge of the uppermost fan-shaped plate 24A, and a hinge 30R is similarly attached to the outer edge of the lowermost fan-shaped plate 24N (see FIG. 4). The wave plates 14 and 14 are connected to each other. FIG. 6 is a plan view when a pair of left and right wave-making plates 14 and 14 are on the same plane (FIG. (1)), and a plan view when the upper end is in a maximum separated state (FIG. (2)). Is shown. As shown in FIG. 6A, in the case of the minimum gap, the connecting unit plate 22 is in the state shown in FIG. Further, as shown in FIG. 6 (2), when the left and right wave forming plates 14 and 14 are operated so as to form a maximum gap, the state shown in FIG. 5 (1) is expanded to the maximum. It becomes a state. Since the connecting unit plate 22 can be rotated around the side edge of the wave forming plate 14 by the hinges 30L and 30R, the wave forming plates 14 seem to be spaced apart from each other as shown in FIG. Even if it is. The connecting unit plate 22 does not form a flow gap between the wave forming plates 14. If water flow from the gaps between the fan-shaped plates 24 is a problem, as shown in FIG. 5, a Teflon (registered trademark) plate 32 is attached to the side edge of each fan-shaped plate 24 to eliminate leakage from the gaps. You may adjust to.
[0011]
As shown in FIG. 1, in the wave making device, all the wave making plates 14 are integrally swung in the front-rear direction with respect to the bottom of the water tank by the operation of the electric cylinder 16 as a whole. The stroke control of the electric cylinder 16 is performed, and the connected wave-making plates 14 are swung so as to produce a phase difference, thereby being operated so as to move along a sine wave when viewed from above. A connecting unit plate 22 is interposed between the wave forming plates 14, which corresponds to the minimum separation position of FIG. 6 (1) and (2) according to the movement of the left and right wave forming plates 14. A fan-shaped opening / closing operation is performed up to the maximum separation position shown. Thereby, when the snake action flap 10 for wave making composed of the wave making plate 14 and the connecting unit plate 22 is viewed from the upper surface, the snake motion is performed. As a result, the general operation of the wave-making snake flap 10 causes the wave-making plate 14 to move back and forth starting from the water bottom as shown in FIGS. Due to the snake motion on the upper edge side of the operation flap 10, the wave in the deep water area compared to the wave wavelength, that is, the wave whose wave motion becomes smaller as the motion of the water particle approaches the water bottom due to the elliptic motion. A speed is given, and at this time, the wave can generate a wave wavelength (Wa) inclined with respect to the wave-making plate 14 of the wave-making snake action flap 10 as shown in FIG.
[0012]
In addition, compared with the conventional wave-making plate having a step formed in a stepped shape, the wave-making plate 14 is continuous without a step, so that ring waves that have occurred near the step edge portion can be prevented, A continuous wave can be generated.
Further, since the connecting unit plate 22 is provided between the wave forming plates 14 so as to fill the gap and perform a fan-like opening / closing motion, it is possible to prevent water from entering and to reduce the level difference and to provide continuity. It can be made into the wave-making board connected in the shape of a broken line with. In addition, while maintaining the main motion in the depth direction, in the width direction of the wave, it has a wave-making plate that is connected in a more continuous polygonal line, and the wave of the three-dimensional wave suitable for the actual ocean What happens is done.
[0013]
Compared to the wave wavelengths to be tested, such as in the shipbuilding field, main motion type wave-making plates that match the movement of water particles are suitable for experiments in relatively deep water tanks. Conventionally, for this purpose, the number of wave-making plates is increased and the width of the wave-making plate is made as narrow as possible, thereby reducing the level difference and obtaining a smooth wave-making surface. Compared with this, according to the snake action flap for wave making and the wave making apparatus using the same according to the present embodiment, the connecting unit that fills the gaps while making the triangular wave making plates 14 swingable with respect to each other. Since the structure in which the plates 22 are connected is adopted, the velocity (V) of water particles in the vertical direction is given to the still water in contact with the flap 10, and this velocity is the bottom surface of the main wave plate and the connection wave plate. It becomes a main type motion that is small in the vicinity of and increases as it approaches the liquid level, so that waves with a three-dimensional directionality can be generated more accurately and economically continuously. Thus, the ring wave generated near the step edge portion can be effectively prevented.
[0014]
【The invention's effect】
As described above, according to the present invention, a plurality of wave-plate pivotable back and forth is pivotally mounted to the bottom of the tank, so as to fill the gap formed in said wave-making plates adjacent the wave-plate A snake action flap composed of a plurality of fan-shaped plates connected to the outer edges of the upper and lower ends of the stack via hinges, and a connecting unit plate that can be opened and closed like a fan. comprising a plurality of actuators for rocking the, since a structure in which a control unit for applying snake operation to the snake operation flaps by swinging sequentially changed in the wave-plate the phase of arrayed said actuator In addition, the snake motion with more continuity is possible in the width direction of the wave while maintaining the main motion in the depth direction, and it generates a three-dimensional wave that follows the actual ocean. Excellent effect that can be obtained.
