不動に固定する。 Since the water turbine device of the present invention has the above-mentioned structure, when installing it in an irrigation canal, the water outlet 11 at the bottom of the water tank 1 is fully open and the guide vane 9 of the jet tube 7 is fully closed. Alternatively, it is suspended by a chain block, and the left and right arm walls 4 at the rear of the water tank 1 are engaged with the rear surfaces of the upper weir plates 2a and 2a of the drop structure 2, and the third
If the water turbine device is installed astride the drop structure 2 as shown in the figure, even if a large amount of water from the waterway flows into the water wheel 1 during the installation work, the water flowing into the water tank 1 will immediately flow from the open water outlet 11. Since water is discharged downstream, there is no need to change the flow of the waterway or close the waterway in advance, and installation work can be carried out while the water is still flowing. In addition, when installing the water turbine device, rubber waterproof packing 21 is installed between the wing walls 4, 4 and the slopes 3a, 3a of the waterway 3, if necessary.
is interposed to prevent water leakage, and the tension jack 14 provided at the upper part of the water tank 1 is extended to fix the device immovably.

If you introduce and rotate the runner 8 of the crossflow turbine,
The rotational force of the water wheel drives the generator 15, and the rotational energy can be converted into electric power and supplied to the user. In addition, in the above case, when the waterway increases due to rain or the like and more water than the required amount flows into the tank 1, the excess water is discharged forward from the overflow port 6 provided at the top of the tank 1. If excessive water is not supplied to the water turbine 1, and if there are many floating objects such as driftwood or dust in the waterway, a dust removal screen 22 is installed in advance in the middle of the water tank 1. This is desirable.

れるなど数々の優れた利点を併有する。 As described above, the water turbine device of the present invention skillfully utilizes the height difference of the existing drop structure of an agricultural canal to install a water wheel, introduces the entire amount of water from the irrigation canal into the water tank, and rotates the water wheel at the lower end. , it is possible to utilize the hydraulic energy extremely effectively, and it goes without saying that there is no need to modify the drop structure in the irrigation canal or any structures attached to it when installing or removing the water turbine. There is no need to change the flow of water or close the waterway, so there is no need to inconvenience water users, and this device can be fitted from above into the weir plate of the drop structure while water is flowing. It is very convenient because it can be fixed in place, and when removed, it can be easily removed by simply pulling the device upwards. In addition, when operating the water turbine, by adjusting the damper installed at the water outlet at the bottom of the water tank and the guide vane installed on the jet tube to the desired positions, it is possible to lower the water level and rotate the water turbine at a low speed while discharging water. In addition to this, it is also possible to completely close the water outlet, raise the water level, increase the head, and rotate the turbine at high speed.When the water level rises above the required limit, excess water can be discharged from the upper overflow port. Since the water is automatically drained out, damage to various parts of the device can be prevented.
