いる。A method is adopted in which the blade angle of the impeller blades is changed depending on the purpose, and the operating methods include hydraulic, electric, 9 mechanical, and combinations thereof. However, until now, the target was a continuous operation pump in which the blade angle could be controlled even during pump operation, and the operating mechanism had to be large, making it difficult to apply it to small diameter bogs and at the same time failing due to the high cost. The present invention is considered to be effective as an energy-saving type pump for farmland, etc., which is operated only for one period per year.
本発明の目的は、風水万機のうちしかも年間の一定期間

更の操作力が小さく。Conventionally, when changing the blade angle of an impeller, emphasis was placed only on changing the blade angle during operation, but for machines that are operated seasonally and only for a few hours a day, it is possible to change the blade angle while the machine is stopped. The blade angle # can be changed while the blade is stopped, and the operating force required to change the blade angle is small.
小型にすることかできる。It can be made smaller.

車羽根角度を変える方式について以下説明する。Next, a mechanism for changing the blade angle of the impeller blades 3 will be explained. FIG. 1 shows the pump in operation. In this operating state, the blade angle of the impeller blades 3 cannot be changed. A method in which the pump stops in the state shown in FIG. 1 and changes the blade angle of one impeller will be described below.

When B is rotated, the coupling 15 connected to the driven bevel gear 16, the drive shaft 14, and the drive nut 1 at the tip thereof.
3 rotates. The bush 26 acts like a guide metal to smoothly transmit the rotation. The drive nut 13 has
Threads are cut on both the outer diameter side and the inner diameter side, and the same type of thread as the drive nut is also cut on the operating shaft 11 and rod 12 sides that contact them. When the drive nut 13 rotates, the operating shaft 11 in contact with the outer cylinder side is fixed in the flow direction (E direction). Move to. As the rod 12 is displaced, the spider 7 moves in four directions, and the spider 7 is connected to the spider 7, and the arm 8 moves in the -@ direction via the pin 10, and the impeller blade 3 connected to the arm 8 is displaced in the @-@ direction.

み、羽根角度を固定することができる。In this way, it is possible to set the blade at a predetermined angle,
After setting, the tomene nozzle 20 is moved in the direction ■ and combined with the tomene 19. The outer circumference of the tomene 19 is threaded, and the same female thread is cut in the tomene 19 part of the operating shaft, so by rotating the tomene handle 20, the tip of the tomene 19 is inserted into the operating shaft 11. , the blade angle can be fixed.
以上のごとく羽根角度をセットし友後は各ハンドル１８

いようにする。Set the blade angle as above and set each handle at 18.
．． 20 is returned to its original position so that it does not become an obstacle during pump operation.
なお、ハンドル軸１８ならびにトメネ用ハンドル２０の
デスチャージケーシング２３の貫通部には、水を洩らさ
ないためのシール遺造とすることは言うまでもない。It goes without saying that the handle shaft 18 and the penetrating portion of the discharge casing 23 of the tomene handle 20 are provided with seals to prevent water from leaking.

もできる。In this example, the drive nut 13 is set so that the movement in the ■-■ direction is slowed by the pitch difference between the inner and outer diameters, but the screws except for the drive nut 13 are set so that the drive shaft 14 and the operating shaft 11 directly engage with each other. You can also change the blade angle by cutting.
本発明によれば、年間のうち２ケ月程度しか運転しない
風水力機械でも省エネルギータイプとして有効である。According to the present invention, even a feng-shui machine that operates only about two months out of the year is effective as an energy-saving type.
すなわち、本発明の可動翼機構を備えたものは１通常の
タイプに比べ１０％程度の原価上昇にすぎず、年２ケ月
程度の運転でも３〜４年で原価償却が可能となる。In other words, the cost of the one equipped with the movable wing mechanism of the present invention is only about 10% higher than that of the normal type, and the cost can be depreciated in 3 to 4 years even if it is operated for about 2 months a year.
さらに、可動翼機構は日常の保守が大変との考えが一般

ば良いからである。Furthermore, it is generally believed that daily maintenance is difficult for a movable wing mechanism, but since it is mechanical, 1.1 there is no need to worry about maintenance. That is, since there is no need to worry about wear of the movable mechanism parts, only the lifespan of the movable mechanism parts, such as corrosion, needs to be considered.
