【発明の詳細な説明】 〔産業上の利用分野〕 本発明はサーボモータの配置を改良したチューブラ水車
に関する。DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a tubular turbine with an improved arrangement of servo motors.
チューブラ水車は、運転状況に合わせランナベーン角度
を操作し、落差、流量変化の広範囲にわたり、高効率運
転が可能な特徴を持っている。Tubular turbines have the feature that they can be operated with high efficiency over a wide range of head and flow rate by operating the runner vane angle according to the driving situation.
ランナベーンの角度の操作源は一般に圧油が用いられて
いる。Pressure oil is generally used as the operating source of the angle of the runner vanes.

４を通り、ランナベーン９に作用されドラフトチューブ
２を通って、下流に放出する間にランナベーン９を回転
させ、主軸３に直結した発電機（図示せず）により発電
をする。As shown in FIG. 2, the tubular water turbine passes the pressure water introduced from the staying 1 through the guide vane 4 for adjusting and guiding the amount of water, the runner vane 9 and the draft tube 2 to discharge the pressure water downstream. The runner vane 9 is rotated and electric power is generated by a generator (not shown) directly connected to the main shaft 3.

軸3aを通って圧油を供給しにくい。The method of operating the angle of the runner vane 9 is the runner boss 8
The main shaft 3a being rotated by a pressure oil introduction device (not shown) installed in the stay vane 5 of the servo motor 22 installed therein.
It is difficult to supply pressure oil through the rotating main shaft 3a while operating the runner vane 9 rotatably attached to the runner boss 8 by the link 12 connected to the runner servo motor 22 by sending pressure oil through .
この方法は、ランナボス８内の空間が大きい、出力が数

ンナサーボモータ22をランナボス８外に設置する方法が
ある。This method is suitable for a large-capacity machine with a large space inside the Lanna Boss 8 and an output of tens of thousands of kilowatts.
In a small-capacity machine with an output of several thousand kilowatts or less, the space inside the runner boss 8 becomes small and it is difficult to incorporate the servo motor 22, so the runner servo motor 22 described in Japanese Patent Publication No. 45584/1984 is used. There is a method to install it outside.

ボス８に回転自在に取付けられたランナベーン９の角度
を任意に調整する。In this method, the stalling 1, the stay vane 5, the guide vane 4, the runner vane 9 and the like have the same flow passage configuration as that of the large-capacity machine, but as shown in FIGS. Installed on the outside of the control lever 18, 21, the pin 20, the disk 15 and the spiral engagement groove 16 that engages with the disk 15, the disk
By operating a servomotor 22 composed of an operation rod 14, a crosshead 13, a link 12, and a lever 11 which are rotatably coupled to the disk 15, the disk 15 is rotated via an operation lever 18. Since it moves in the spiral groove to be engaged and moves to the left and right as shown by an imaginary line in the drawing, the runner vane 9 rotatably attached to the runner boss 8 through the crosshead 13, the link 12, and the lever 11 together with the operation rod 14. Adjust the angle arbitrarily.

ける連結部をもった本機構は、ランナベーン操作推力と
回転を受ける軸受が二ケ所となるので、下記の欠点があ
る。A considerable force is required for the angular movement and holding of the runner vane 9, and even with a small-capacity machine with a turbine output of several thousand kilowatts, an operating force of several tens of tons is applied to the disk 15 and the operating rod 14,
Change to left and right reciprocating movement by the vertical spiral groove 15 of the lever 18,
Furthermore, this mechanism, which has a connecting portion that receives the thrust of the operating rod 14 that rotates with the runner vane 9 and the runner boss 8 and reciprocates left and right together with the disk 15, has two locations for the runner vane operating thrust and the bearing that receives the rotation. , Has the following drawbacks.
操作レバー18の上下運動と螺旋溝16により左右の往復運
動に変えること等による機構が複雑になり、組立作業が
容易でない。The vertical movement of the operating lever 18 and the spiral groove 16 make the mechanism complicated by changing to a left and right reciprocating movement, and the assembling work is not easy.
また上流側のは空間部が多く、サーボモータが外部にあ
り機構が複雑になる。In addition, the upstream side has a lot of space and the servomotor is located outside, which complicates the mechanism.
又図２では回転中の主軸3aに圧油を供給すると、圧油は
回転中の遠心力に戻される傾向にあり圧力を高くするの
で、圧油導入装置の大型化は避けられなかった。Further, in FIG. 2, when pressure oil is supplied to the rotating main shaft 3a, the pressure oil tends to be returned to the centrifugal force during rotation and the pressure is increased, so that the pressure oil introducing device must be increased in size.
本発明の目的は、水車ケース内の機構を単純化すると共

Since the servomotor equipped with the slide bearing is prevented from rotating and only reciprocates, the servomotor can be arranged in the upstream turbine case.
以下、本発明の実施例を第１図に示すチューブラ水車の
断面図により説明する。An embodiment of the present invention will be described below with reference to a sectional view of a tubular turbine shown in FIG.

９の操作角度を変える。In the runner vane operating mechanism 12, the reciprocating motion of the operating rod 14 transmits the reciprocating motion to the cross head 13, and the transmission force of the cross head 13 converts the reciprocating motion into the rotary motion by the link 12A and the lever 12C, thereby rotating the stem 12C. Then, the operation angle of the runner vane 9 is changed.

うになった。As described above, the slide bearing 29 of the present invention rotates the operating rod 14 and the thrust receiving plate 27 inside, and at the same time, the operating rod 14
As a result of interrupting the transmission of the rotation of the servomotor 22 to the servomotor 22, the servomotor 22 is no longer rotated and can be arranged in the top cover 30 which has not been used until now.
この結果、圧油配管31からの圧油は静止しているサーボ
モータ22に出し入させるので、圧油の供給がスムーズに
出来のようになり、図示していない圧油導入装置を小型
化できる。As a result, the pressure oil from the pressure oil pipe 31 is moved in and out of the stationary servo motor 22, so that the pressure oil can be smoothly supplied, and the pressure oil introducing device (not shown) can be downsized. .
