本発明は１港の入口に設けられる防波用のスウィングゲ
ートに関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a swing gate for breakwater provided at the entrance of a port.

転し、ゲー）０１を全閉していた。A conventional swing gate will be explained with reference to FIG. 3. Figure 3 is a view of Shigate 01 from the sea side. 02 is the embankment at the entrance of the port, 03 is the support that supports the gate 1, 04 is the gear attached to the support, 05 is the rack for giving rotational motion to the gear 04, and 06 is the hydraulic series 7 that moves the rack O5. It is. Normally, when a ship is entering or exiting a port, game) 01 is fully open. However, as the waves inside the embankment increase during typhoons, etc., it is necessary to close off the opening with Gate 1 to prevent collisions with ships, etc. When closing, the gate) 01 was rotated by a drive device such as a hydraulic cylinder 06, and the gate) 01 was fully closed.
従来によれば、ゲート０１を開閉しようとする時、水面
に波立ちがあり、それによる荷重が油圧シリンダー等の
駆動装置に負荷となって作用するので駆動装置が大がか
りとなる。Conventionally, when attempting to open or close the gate 01, there are ripples on the water surface, and the resulting load acts on a drive device such as a hydraulic cylinder, making the drive device bulky.
また、その波立ちによる荷重の方向は一定とは限らず繰
シ返し荷重となって駆動装置に作用し、疲労に対する配
慮も必要となる。Furthermore, the direction of the load due to the undulations is not necessarily constant and acts on the drive device as a repetitive load, so consideration must be given to fatigue.
本発明は上記環境においても負荷影響の少ない駆動装置
を具えたスウィングゲートを提案するものである。The present invention proposes a swing gate equipped with a drive device that is less affected by load even in the above environment.
本発明によるスウィングゲートは、堤防等の構造物に垂
直の支承部を介して開閉可能に設けられたゲートの他方
側の没水部に推力駆動装置を設けたことを特徴とするも
のである。The swing gate according to the present invention is characterized in that a thrust drive device is provided in the submerged part on the other side of the gate, which is provided in a structure such as an embankment so as to be openable and closable via a vertical support part.
しかして、ゲートの開閉は没水部の推力駆動装置によシ
行なわれるので、ゲートに波立ち等の負荷が作用しても
駆動装置に上記負荷が直接的に作用することはない。Since the gate is opened and closed by the thrust drive device in the submerged section, even if a load such as waves is applied to the gate, the load does not directly act on the drive device.
本発明によるスウィングゲートを第１図及び第２図に示
す１実施例により°説明する。A swing gate according to the present invention will be explained with reference to an embodiment shown in FIGS. 1 and 2.
第１図及び第２図において、１はゲート。In FIG. 1 and FIG. 2, 1 is a gate.
２は堤防、３は支承部、４はブラケットである。支承部

全開直前にそれぞれブレーキをかけることもできる。2 is an embankment, 3 is a support portion, and 4 is a bracket. A side thruster 5 is installed in the submerged part of the gate 1 on the other side of the support part 3. The gate 1 is opened and closed by rotating the side thruster 5 in forward and reverse directions. Also 9
6 in the figure is a fixing device driven by a power cylinder for the gate tortoise against the embankment 3, as shown in figure 2! - A fixing device is also provided on the open side of the gate λ.In addition, if a variable pitch side thruster 5 is installed, the opening/closing speed of the gate 1 can be adjusted, so the brakes can be applied just before fully closing and immediately before fully opening. You can also apply it.
また、サイドスラスタ−の代シにウォータージェットを
用いてもよい。Also, a water jet may be used in place of the side thruster.

〔発明の効果〕
従来の方式が支承部を直接回転させる為に。If a gate valve is installed at the entrance and exit of the side thruster or water jet, it can be applied to gates that require watertightness. [Effects of the invention] The conventional method rotates the support directly.
波等の瞬間的な変動荷重が拡大されて駆動装置に伝えら

変動荷重を受けてもそれほど影響を受けず、装置自体は
大がかりなものとする必要がなく経済性にすぐれている
。Compared to instantaneous fluctuating loads such as waves, which are magnified and transmitted to the drive device, the drive device of the present invention is of a thrust type, so it is not affected much by fluctuating loads, and the device itself is not large-scale. It is highly economical as there is no need to use it.
