Description of the Related Art Among cross-flow turbines, there is a simplified cross-flow turbine that is applied when the amount of water is small or the head of water is small. This simple cross-flow turbine has no guide vane and is configured as shown in FIG. That is, the runner 1 is rotatably supported via the rotary shaft 2, a casing 3 for supplying water to the runner 1 is provided on the runner 1, and the casing 3 has a water conduit 4 with bolts 5 and the like.

量でクロスフロー水車の出力の計画を立てねばならず、
従って出力の小さなものとなる。In the cross-flow turbine having such a structure, since there is no guide vane, the flow rate cannot be adjusted, and it is necessary to always flow a fixed amount of water. In reality, the amount of water varies depending on the amount of rainfall and the season, but it is necessary to plan the output of the cross-flow turbine with the flow obtained over a long period of time, that is, the small flow.
Therefore, the output is small.

という問題が残る。However, there is a drawback that only a small output can be obtained even when the amount of water is large. On the other hand, the cross-flow turbine with the above-mentioned guide vane, which can increase the flow rate to obtain a large output and decrease the flow rate to obtain a small output, may be used, but the problem of high cost remains.

へのみ水が流れることになる。Next, the operation of such a cross flow turbine will be described. Depending on the amount of water at the location where the cross-flow turbine is used, it is determined whether to open or close each of the divided flow paths. When opening, the on-off valve 8 is attached as shown in FIG. Attach the on-off valve 7. In this way 4
Install one of the open / close valves for all of the two divided flow paths. 4 (a) and 4 (b) are cross-sectional views of the case where the divided channel is opened and the case where the divided channel is closed. Generally, when the amount of water is large, all the divided channels are opened, and when the amount of water is small, only some of the divided channels are opened. Water flows only to the L 1 to L 4 portions of the runner 1 corresponding to the open divided flow paths of L 1 to L 4 corresponding to the respective divided flow paths.

If it is set to 1: 2: 3: 4, as shown in Table 1, the flow rate can be changed from 10% to 100% in 10% steps.
Next, L 1 : L 2 : L 3 = 14: 2 with three divided channels.
At 8:56, the flow rate can be changed every 14% as shown in Table 2.

In order to open the divided flow path as shown in FIG. 6A, the bolt 5 is inserted through the insertion hole 9 at the lower end,
As shown in FIG. 6B, the bolt 5 is inserted into the insertion hole 9 at the upper end to close the divided flow path. In the case of FIG. 6B, it is necessary to prevent the insertion hole 9 at the lower end from protruding into the divided flow path.

If the drop is small, even if the on-off valves 7 and 8 are used, water leakage cannot be avoided, but the on-off valves 7 and 8 can be inserted and withdrawn. A loose tube may be added to the side of the water conduit 4 in order to facilitate the insertion and withdrawal of these on-off valves.

る。As can be seen from the above description, according to the cross-flow turbine of the present invention, the flow rate of water can be adjusted by partitioning the flow path and adding an on-off valve, and the amount of water can be adjusted without a guide vane. Great power can be obtained in response to changes. Then, the flow rate can be adjusted with a smaller gap by changing the interval between the partitions and combining them.
