本発明は水力発電設備に係り、特に、水力発電
機械をダムまたは水路に設ける水力発電設備に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to hydroelectric power generation equipment, and more particularly to hydroelectric power generation equipment in which a hydroelectric power generation machine is installed in a dam or a waterway.
従来の水力発電設備は、その水力発電機械を、
ダムまたは水路に設けたゲートから離れた下流に
建設されている発電所内に設置して発電し、その
電力を送電する方式が一般的である。 Conventional hydroelectric power generation equipment uses its hydroelectric power generation machine as
A common method is to generate electricity by installing it in a power plant built downstream away from a gate installed in a dam or waterway, and then transmitting the generated electricity.
しかし、これらの水力発電設備を建設するに
は、川幅を拡げたり、あるいは別個に導水路を設
けて設備とダムとを連結する建設工事が必要であ
る。従つて、土木費を含めたこれら水力発電設備
の建設費は非常に多額なものとなる。 However, in order to construct these hydroelectric power generation facilities, it is necessary to expand the width of the river or construct a separate waterway to connect the facilities and the dam. Therefore, the construction costs of these hydroelectric power generation facilities, including civil engineering costs, will be extremely large.
近年、水力資源の開発と経済化を計る手段とし

機械の製作に、より複雑な制約をうけることにな
りその実現が困難であつた。 In recent years, attempts have been made to attach hydroelectric power generation machines directly to gates of dam discharge channels, irrigation canals, etc. as a means of developing and economicizing hydropower resources.
In this case, when inspecting or repairing the hydroelectric machine, the gate is opened and all the water in the waterway is released. This is not preferable from the standpoint of effective use of water, and especially when a plurality of hydroelectric power generation facilities are installed, the amount of water loss becomes large and becomes a problem. Furthermore, when installing a hydroelectric generator at a gate, gate manufacturing laws and regulations are applied, which imposes more complicated restrictions on the manufacture of the hydroelectric generator, making it difficult to implement.
本発明の目的は、上記問題点を解決し、水路に
合理的に設置可能な水力発電設備を提供すること
にある。 An object of the present invention is to solve the above problems and provide a hydroelectric power generation facility that can be rationally installed in a waterway.

る。 The present invention provides a hydroelectric power generation facility in which a gate equipped with a suction pipe and a hydroelectric power generation machine disposed in contact with the upstream side of the gate are movably arranged in a dam or waterway, and the gate is equipped with a water drain and a disconnection gate. ,
The hydraulic power generating machine is characterized in that it can be raised and lowered separately from the gate by means of a lifting device to which it is detachably attached.

2. It is constructed integrally with the runner 13, speed ring 14, stay vane 15, casing B16, etc., and is bolted to the lifting device 6 via the support stand 18, the lower part of the casing B16, and the support arm 20. A suction pipe B7 and a casing A8 are fixedly attached to this elevating device 6, and have a gap g for removal as shown in FIG. 2 showing details of sections A and B in FIG. Bolted to joint structure. In other words, a hollow capacity is installed within the lifting device, and a hydroelectric power generation machine is placed within the container. In these combination structures, water flows in and out as shown by the arrows, driving the runner 13 to rotate. In this structure, the drain gate 3 and the flange at the end of the suction pipe B7 are simply in contact with each other, and no tightening structure using bolts or the like is used, so the main gate 1 or the lifting device 6 is It can be raised and lowered separately.

よつて行なわれる。 Next, the case of performing power generation operation, inspection, etc. will be explained. When generating power, first, by moving the drain and break gate 3 downward to open it, water from the water channel A22 flows in from the casing A8, passes through the side of the generator 12, rotates the runner 13, and starts power generation. Then, it flows out into the waterway 23 via the suction pipe B7 and the suction pipe A4. Control of the power generation equipment is carried out by a control device arranged on the side wall of the lifting device.

得るという実用的効果を奏することができる。 According to this embodiment, when inspecting or repairing hydroelectric power generation machines, it is possible to perform inspections and repairs without discharging water in the waterway, so even if multiple hydroelectric power generation facilities are installed, unnecessary water loss is avoided. It can be prevented. In addition, since the hydroelectric power generation machine can be configured separately from the main gate, precision in manufacturing and installation can be ensured, and it has the practical effect of being able to continue safe operation with easy maintenance when installed in a waterway. .
