Description
本発明は、河川の流力を受けて回転する発電用等の水車に対して、これに向って流れてくるゴミを事前に排除させるようにした水車に対するゴミ流入排除装置に関する。 The present invention relates to a waste inflow elimination device for a water turbine that allows a turbine for power generation that rotates in response to the flow force of a river to exclude waste flowing toward the turbine in advance.
従来、河川等に設置し、その流力を利用して水車を回転させ、同回転力に基づき発電を生じさせるようにした発電用水車は存在する（例えば、特許文献１参照。）。 そして、この種の水車に於いて、水中のゴミ等を吸い込まないようにするために、図１に示すように、その取水口側に先細円錐状を呈するゴミ通過阻止用カバーＭを被せることによって、ゴミの吸込みを防止する様に構成したものがある。 2. Description of the Related Art Conventionally, there is a power generation water turbine that is installed in a river and the like, and a water turbine is rotated using the flow force to generate power based on the rotational force (see, for example, Patent Document 1). And in this kind of water wheel, in order to prevent inhalation of underwater dust etc., as shown in FIG. 1, by covering the water intake side with a dust passing prevention cover M having a tapered conical shape. Some are configured to prevent the inhalation of dust.
上記したようなカバーＭを用いたものであると、細かいゴミによる目詰まりに対しては、定期的な清掃作業で対応可能とする。 然し乍、大きなゴミが引っかかった際には瞬時に取水に齟齬をきたしてしまい、機能不良が生じてしまうこととなる。 このような場合、緊急的清掃処理を行わなければならず、そのために水車の保守管理には継続的な監視作業と、臨時的清掃作業の体制を確立しておかなければならず、従って、水車の保守作業の経済的負担性が著しく伴うことを余儀なくされた。 If the cover M as described above is used, clogging with fine dust can be dealt with by a regular cleaning operation. However, when large trash is caught, water will be drowned instantaneously, resulting in malfunction. In such a case, an urgent cleaning process must be performed, and for this purpose, a continuous monitoring operation and a temporary cleaning operation system must be established for maintenance of the turbine. The economic burden of maintenance work was forced to accompany.
本発明はこのような従来の問題の解消化を果たすように構成した水車に対する新規のゴミ流入排除装置の提供を図ったものである。 The present invention is intended to provide a novel waste inflow eliminating apparatus for a water turbine configured to solve such a conventional problem.
本発明は、 河川の水中に位置させることにより、流れに基づく水圧を受けて水車を回転させて発電作用を奏させるようにした発電用水車であって、ゴミ通過阻止用カバーを当該発電用水車の取水側開口部に被せることに依って、水中に浮遊する細かいゴミに対する吸込みを阻止させるように構成した発電用水車を実施対象とし、ゴミ排除用体を、上記ネット製カバーの先端に、起伏可能にしてかつ元状復帰可能に取付けたことを特徴とする水車に対するゴミ流入排除装置に係る。 The present invention relates to a power generation water turbine that is positioned in the water of a river to receive a water pressure based on a flow and rotate the water wheel to produce a power generation operation, and the dust passage prevention cover is provided with the power generation water wheel. A water turbine for power generation configured to prevent suction of fine dust floating in the water by covering the intake side opening of the water intake, and the dust removal body is undulated at the tip of the net cover The present invention relates to a dust inflow elimination device for a water turbine, characterized in that it is mounted so that it can be restored to its original state.
本発明は、先細三角形状を呈するゴミ排除用体２を、既存のゴミ通過阻止用カバーＭの先端に、起伏可能にしてかつ元状復帰可能に取付けたから、例えば、木の枝、木の葉、海藻、シート状ビニール片等、比較的大きなゴミがゴミ排除用体２に引っかかった際、水流抵抗の増加に基づき、図３に示す状態、並びに図４の鎖線で示す状態に首振り的な屈折をなすこととなる。 このような転動的な回動転移に基づき、上記ゴミは、今度は水流圧力により引き剥がされる力として作用する位置に移動するため、水流により自然に引き剥がされると共に、ゴミ通過阻止用カバーＭの外側に移動させるような流れ的案内が成されることとなる。 従って、当該ゴミがカバーＭに被さって機能不良を来してしまうような事態発生を未然に回避させる。 In the present invention, the dust removing body 2 having a tapered triangular shape is attached to the tip of the existing dust passage prevention cover M so that it can be raised and lowered and can be restored to its original shape. When a relatively large trash such as a sheet-like vinyl piece is caught on the trash-removing body 2, the swinging refraction is caused in the state shown in FIG. 3 and the state shown by the chain line in FIG. Will be done. Based on such a rotational rotation, the dust moves to a position where it acts as a force to be peeled off by the water flow pressure, so that the dust is naturally peeled off by the water flow and the dust passage prevention cover M Thus, the flow guide is moved so as to be moved to the outside. Therefore, it is possible to avoid the occurrence of a situation where the dust covers the cover M and causes a malfunction.
図において、Ｓはドラム体Ａの内部に水車Ｂを収装して成る既存の発電用水車であって、河川の水中に位置させることにより、流れに基づく水圧を受けて水車Ｂを回転させて発電作用を奏させるものである。 このような形式の発電用水車Ｓは公知の技術に属し、多数個を並列状に位置させて設置し、河川の水位に基づき浮力に基づき自動的なる水位保持がなされるように構成してある。 In the figure, S is an existing power generation water turbine in which a water turbine B is housed inside a drum body A. By positioning the water turbine in the river water, the water turbine B is rotated by receiving water pressure based on the flow. The power generation action is achieved. Such a type of power generation turbine S belongs to a known technique, and is installed in parallel with a large number of water turbines, and is configured to automatically maintain the water level based on the buoyancy based on the water level of the river. .
Ｍはゴミ通過阻止用カバーであって、上記した発電用水車Ｓの取水側開口部に被せることに依って、水中に浮遊する細かいゴミに対する吸込みを阻止させるためのものである。 そして、当該カバーＭは定期的な清掃作業を施すことに依り、ゴミによる目詰まりを解消するような管理体制を採るものである。 なお、図示の実施例にあっては、当該カバーＭとして先細円錐形状を呈するのとしてあるが、このような形状に限定されるものではなく、発電用水車Ｓの取水側開口部をカバーしてゴミ等の吸込みを阻止可能とするものであれば如何なる形態であっても可とする。 但し、後述するゴミ排除用網体２の取付けが可能とする形態を具えたものとする。 そのためには、前方に斜状に突出するような形態、例えば図示のような先細円錐形状のような流線型状とすることが望ましい。 そして、当該カバーＭは図示のような網状のもの以外、細い鉄棒で格子状或いは簀子状に組んだものであっても良い。 M is a dust passage blocking cover for blocking the suction of fine dust floating in the water by covering the intake side opening of the power generation turbine S described above. And the said cover M takes the management system which eliminates clogging by garbage by performing a regular cleaning operation | work. In the illustrated embodiment, the cover M has a tapered conical shape, but is not limited to such a shape, and covers the intake side opening of the power generation turbine S. Any form is possible as long as it can prevent the suction of dust and the like. However, it is assumed that it has a configuration that enables attachment of a dust removal net 2 described later. For this purpose, it is desirable to have a shape that projects obliquely forward, for example, a streamline shape such as a tapered cone shape as shown in the figure. The cover M other than the net-like one shown in the figure may be one assembled in a lattice shape or an insulator shape with a thin iron rod.
本発明は上記したようなゴミ通過阻止用カバーＭを具えた発電用水車Ｓを実施対象とするゴミ排除装置に関するものであり、下記するような構成を具えている。 The present invention relates to a dust removal apparatus that implements a power generation water turbine S provided with a dust passage prevention cover M as described above, and has the following configuration.
１は上記したゴミ通過阻止用カバーＭの先端に固定化するための取付け具であって、先細三角形状を呈するゴミ排除用体２を、その基端側中心部で左右方向に起伏自在とするように取付けられている。 なお、図示の実施例にあっては、左右方向に起伏自在とするように構成してあるが、例えば自在継手金具を用いることに依り、上下若しくは左右方向、或いは無指向的な全方向に起伏自在とするように構成しても良い。 更に、上記ゴミ排除用体２は図示のような網状のもの以外、細い鉄棒で格子状或いは簀子状に組んだものであっても良い。 Reference numeral 1 denotes an attachment for fixing to the tip of the dust passage prevention cover M, and the dust removal body 2 having a tapered triangular shape can be raised and lowered in the left-right direction at the base end side central portion. As installed. In the illustrated embodiment, it is configured to be able to undulate in the left-right direction. However, for example, by using a universal joint bracket, the undulation is performed in the up-down direction, the left-right direction, or in all non-directional directions. You may comprise so that it may be made freely. Further, the dust-removing body 2 may be one that is assembled in a lattice shape or an insulator shape with a thin iron bar other than the net-like one as shown in the figure.
また、上記したゴミ排除用体２と取付け具１との接続部分には、図面に於いては省略してあるが、これが倒された状態から元状に復帰すための既存の復元バネ機構を組み込むことに依り、元状復帰機能が付与されているものとする。 そして、当該復元バネ機構に関する制限性は無く、通常の復元機能を有するものであれば如何なる形態のものであっても可とする。 In addition, the connecting portion between the dust removing body 2 and the fixture 1 is omitted in the drawing, but an existing restoring spring mechanism for restoring the original state from the state in which the dust removing body 2 is tilted is provided. It is assumed that a function for returning to the original state is given by incorporation. And there is no restriction | limiting property regarding the said restoring spring mechanism, and what kind of thing of any form is possible if it has a normal restoring function.
図２に示す状態にあって、木の枝、木の葉、海藻、ビニール片等、比較的大きなゴミがゴミ排除用体２に引っかかった際、この部分に当たる水流の圧力が増加し、この圧力に基づきゴミ排除用体２が図３に示す状態、並びに図４の鎖線で示す状態に首振り的な屈折をなすこととなる。 この状態にあっては付着したゴミは水流とほぼ平行するような状態に転動されたこととなり、従って、水流の圧力は上記ゴミを引き剥がす力として作用することとなり、ゴミは自然に引き剥がされることとなる。 そして、引き剥がされた後は、ゴミ除去用網体２の倒伏状態の角度に基づき、これに沿う水流の方向に引き剥がされて流れるため、カバーＭを避けてその外側に移動させるような案内が成されることとなる。 従って、当該ゴミがカバーＭに被さって水車の機能不良を来してしまうような事態発生を未然に回避させることとなる。 In the state shown in FIG. 2, when relatively large garbage such as tree branches, leaves, seaweed, vinyl pieces, etc. is caught on the dust removal body 2, the pressure of the water flow hitting this part increases, and based on this pressure The dust-removing body 2 is swung into the state shown in FIG. 3 and the state shown by the chain line in FIG. In this state, the attached dust was rolled in a state almost parallel to the water flow, and therefore the pressure of the water flow acts as a force for peeling off the dust, and the dust is peeled off naturally. Will be. Then, after being peeled off, based on the angle of the lying state of the dust removal net 2, it is peeled off and flows in the direction of the water flow along this, so that the guide is moved away from the cover M. Will be made. Accordingly, it is possible to avoid the occurrence of a situation in which the dust covers the cover M and causes a malfunction of the water turbine.
