Description
本発明は小水力発電装置用ゴミスクリーン装置に関する。The present invention relates to a dust screen device for a small hydroelectric generator.
これまで小水力発電装置は小水力発電タービンの上流側に固定式のゴミスクリーンやかき揚げ式の除塵装置などが配置されてきた。
特許文献1のように増水や気象条件など用水路管理上の要件を受けて小水力発電機や除塵装置を水路から引き上げる機構が提案されていた。
特許文献2のようにスクリーンに停滞したゴミを陸上側に引き上げる方法が提案されていた。
特許文献3のように流体動力を利用して常に回転しながら、ゴミを陸上側に上げる方法が提案されていた。In the past, small hydroelectric power generation apparatuses have been provided with a fixed trash screen, a kakiage type dust removal apparatus, and the like upstream of the small hydroelectric power generation turbine.
A mechanism for lifting a small hydroelectric generator and a dust removing device from a water channel in response to requirements for irrigation channel management such as water increase and weather conditions as in

本発明が解決しようとする課題は、用水路に小水力発電装置を配設した場合、ゴミなどの異物が水力発電タービン(4)、ガイドベーン(16)など、小水力発電装置内の部品に絡み付くなどして、性能低下など悪影響を及ぼすため、小水力発電装置の上流側に従来形のゴミスクリーンを設置して対応していたが、ゴミ停滞による運転性能低下やゴミ引揚装置費用および該ゴミ収集廃棄処理の費用が発生していた。The problem to be solved by the present invention is that when a small hydroelectric generator is disposed in a water channel, foreign matters such as dust are entangled with components in the small hydroelectric generator such as the hydroelectric turbine (4) and guide vanes (16). In order to adversely affect performance degradation, etc., a conventional garbage screen was installed upstream of the small hydroelectric generator. Expenses for disposal were incurred.
小水力発電装置を配設する水路の上流側に一時的にゴミを捕獲するためのゴミスクリーン(7)を設置して、ゴミが小水力発電機に性能低下を及ぼす状況を検知して、水力発電タービン(4)が水上に退避すると同時またはその後、捕獲したゴミを下流に放流する。A dust screen (7) for temporarily capturing garbage is installed upstream of the water channel where the small hydroelectric generator is installed, and the situation where the garbage causes a performance degradation on the small hydroelectric generator is detected. At the same time or after the power generation turbine (4) retreats on the water, the captured garbage is discharged downstream.
小水力発電装置を配設する水路の上流側に一時的にゴミを捕獲するためのゴミスクリーン(7)と水力発電機タービン側水路(18)に水が流れ込まないように機能する水門扉(15)を設置し、該ゴミスクリーン(7)にゴミが停滞して小水力発電装置に悪影響を及ぼす状況を検知して、該水門扉(15)を働かせて、水力発電タービン側水路(18)とは異なる水路を経由して、捕獲したゴミを下流に放流する。A trash screen (7) for temporarily capturing trash on the upstream side of the water channel where the small hydroelectric generator is installed, and a sluice gate (15) that functions to prevent water from flowing into the hydroelectric generator turbine side water channel (18). ) To detect the situation where the trash stagnates on the trash screen (7) and adversely affects the small hydroelectric generator, and the sluice door (15) is operated to connect the hydropower turbine side waterway (18) and Discharges the captured garbage downstream through different waterways.
ゴミスクリーン(7)において、スクリーン面を水深が増加する方向で下流側に傾斜させることでスクリーン(7)に停滞したゴミをゴミスクリーン(7)の下方に押しやる効果が得られる。In the dust screen (7), by tilting the screen surface downstream in the direction of increasing the water depth, an effect of pushing the dust staying on the screen (7) below the dust screen (7) can be obtained.
ゴミスクリーン(7)に停滞したゴミが小水力発電装置に悪影響を及ぼす状況の検知は、該ゴミスクリーン(7)に働く流体抵抗の増加や、水路の流量とゴミスクリーン(7)付近の水位および小水力発電装置の発電の変化によって得られる。The detection of the situation where the trash stagnating on the trash screen (7) has an adverse effect on the small hydroelectric generator is based on the increase in fluid resistance acting on the trash screen (7), the flow rate of the water channel, the water level near the trash screen (7) Obtained by changes in power generation of small hydroelectric generators.
本発明によって、ゴミスクリーン(7)に停滞したゴミが小水力発電装置に悪影響を及ぼす状況をいち早く検知し、小水力発電装置に悪影響が及ばない状態にした後で、該ゴミを小水力発電機の下流に放流する処理を行うことで、小水力発電機への悪影響を抑制しながら、自動運転を継続することができる。 これによって、ゴミによる発電量減少の抑制、保守要員出動回数の低減などの効果が得られる。According to the present invention, after the situation where the stagnation on the dust screen (7) has an adverse effect on the small hydroelectric generator is quickly detected and the small hydroelectric generator is not adversely affected, the garbage is removed from the small hydroelectric generator. By performing the process of discharging to the downstream, automatic operation can be continued while suppressing adverse effects on the small hydroelectric generator. As a result, effects such as suppression of power generation reduction due to garbage and reduction of the number of dispatch of maintenance personnel can be obtained.
ゴミスクリーン(7)で捕獲したゴミの収集廃棄作業が不要になる。It is not necessary to collect and discard the trash captured by the trash screen (7).
用水路に配設された水力発電タービンの上流側にゴミスクリーンを配置し、水力発電タービンにゴミが悪影響を及ぼさない状態で、ゴミを下流側に流すことで、係員が現地でのゴミ除去作業を行うことなく、自動処理で継続的な運転を実現する。A trash screen is arranged upstream of the hydroelectric turbine installed in the irrigation channel, and the trash is allowed to flow on the downstream side in a state where the garbage does not adversely affect the hydroelectric turbine, so that the staff can remove the garbage on-site. Realize continuous operation with automatic processing without any need to do so.
図1に本発明の小水力発電装置用ゴミスクリーン装置における請求項1の水力発電タービン(4)が水上に退避する前を示した実施例の構成を示す。
水力発電タービン(4)の上流側にゴミスクリーン回転軸(8)を持つ、可動式のゴミスクリーン(7)が配置されている。水力発電タービン(4)はギヤボックス(5)と発電機(6)と架台(14)に組みつけられて一体化され、駆動機(10)によって架台回転軸(13)を中心に回転する構造となっている。

A movable dust screen (7) having a dust screen rotating shaft (8) is arranged on the upstream side of the hydroelectric turbine (4). The hydroelectric turbine (4) is assembled to and integrated with the gear box (5), the generator (6), and the gantry (14), and is rotated about the gantry rotating shaft (13) by the drive machine (10). It has become.
The gantry rotating shaft (13) and the trash screen rotating shaft (8) are connected by a link bar (9). When the drive machine (10) rotates the gantry (14), the hydroelectric turbine (4) is lifted onto the water. At the same time, the link bar (9) is pressed and the lower end of the dust screen (7) rotates downstream as shown in FIG. 2, and the captured dust is discharged downstream.

The hydroelectric turbine (4) rotates inside the duct (19). The rotational force is transmitted from the main shaft (17) to the gear housing (5) and is transmitted to the generator (6).
A dust screen (7) is installed on the upstream side of the hydroelectric turbine (4), and a sluice door (15) is provided below it.
The sluice gate (15) is connected to the drive unit (10) by the link bar (9), and when the drive unit (10) opens the sluice door (15) downward, the water flowing from the upstream is captured by the dust screen (7). Together with the collected waste, it is discharged downstream without passing through the hydroelectric turbine side water channel (18).
ゴミスクリーン(7)には、捕獲したゴミを離れやすくするために振動、回転、空気噴出、水流噴出装置を付加することができる。To the garbage screen (7), vibrations, rotations, air jets, and water jets can be added to make it easy to leave the captured garbage.
