Abstract:
PURPOSE: To obtain an apparatus, which inspects a water wheel safely, positively and quickly without water draining work.
CONSTITUTION: A water-wheel inspection apparatus contains an underwater- inspection-robot pushing and returning device 5 in case body 4. The case body 4 is opened to a draft tube 2, which is connected to a water wheel 1, and connected to a manhole 3, which can be opened and closed with a cap. The pressure in the case body 4 is equal to the pressure in the draft tube 2. The device is supported so that the device can be pushed and retreated in the draft tube 2 with a driving device. An underwater inspection robot 10, to which a cable 11 wound around a cable winding device 9 is connected, is mounted on the device 5. The pressure in the case body 4 is made equal to the pressure in the draft tube 2. Under this state, the cap 3a is opened, and the unerwater- inspection-robot pushing and returning device 5 is pushed into the draft tube 2. Thus, the underwater inspection robot is started or made to return.
