As shown in FIG. 1 (b), the cross-flow turbine has the runner 1 protruding leftward from the support frame 3, so that the edge of the water tank is used as a base 17 as shown in FIG. It can be operated just by attaching it. In the conventional cross-flow turbine, the runner 23 is located right above the discharge pipe 30 as shown in FIG. 6, so that a pair of projecting foundations 32 are formed as shown in FIG. 34 must be formed.

できる。The water pipe 4 is assembled so as to cover the runner 1 from above, and the gap between the runner 1 and the nozzle pipe 4a can be adjusted to an arbitrary value. The gap can be increased by sandwiching a shim between the left stay 4c and the mounting frame 3 in FIG. 1B or reducing the shim between the right stay 4c and the mounting frame 3. By performing the operation, the gap can be reduced. If this gap is large, leakage water increases and the turbine characteristics deteriorate, but the left and right gaps can be adjusted arbitrarily.

や材料の統合が促進でき、量産に適する。The outer diameter and width of the runner are determined by the water drop and the amount of water in the turbine. Generally, the outer diameter of the runner is selected in several ratios at a certain ratio, and the width of the runner is determined by the width of the runner. It is designed to be adjusted, the width dimension is set to several types at a certain ratio, and a water turbine close to the specification is applied. According to the cross flow turbine according to the present invention,
The length of the base 6 and the positions of the mounting holes of the base 6 and the stays 6c are changed according to the length of the runner 1, and the waterproof plate 14
The length of the support frame 3, the bearing box 2 and the like need not be changed. The cross-sectional shape of the part whose length changes in the extending direction of the water pipe 4 is the same, and it is sufficient to adjust only the length. Therefore, commonization and standardization of parts, or integration of processing and materials can be promoted, which is suitable for mass production.

スフロー水車の据付が簡易かつ迅速に行える。As can be seen from the above description, the cross-flow turbine according to the present invention mainly comprises a runner and a water pipe, which are supported by a pair of support frames. Therefore, the number of components of the cross flow turbine is smaller than in the conventional case, and the structure of the cross flow turbine can be greatly simplified. Moreover, since the pair of support frames are connected by the water pipe, the water pipe also functions as a connecting member, and the overall rigidity of the cross flow turbine is not inferior to the conventional one. And since the runner was mounted via a bearing that protruded to one side of the support frame, there was no need to form recesses or protrusions as a basis for installing the crossflow turbine, making the installation of the crossflow turbine simple and easy. Can be done quickly.
