Abstract

A hydraulic turbine suspending device is provided which facilitates the positioning of a hydroelectric generator in a waterway, and which is easy to work on. The hydraulic turbine suspending device is a support that suspends a hydraulic turbine (10) in a waterway by laterally bridging the same, and comprises a combination of a suspending beam (2) positioned in parallel with the upstream and downstream sides of the waterway; a plurality of stanchions (5) that support the edges of the suspending beam (2) in a horizontal position on the outside of the waterway; and a floor plate (6) provided in a tensioned state to the suspending beam (2).

Claims

1. A waterwheel suspending device that is a support device which is transversely provided so as to bridge a water channel to suspend a waterwheel, the device comprising:

a combination of a plurality of spliceable suspension main bodies joined in a pipe hole of the suspension main body via a joining element having a rectangle block shape and arranged in parallel on an upstream side and a downstream side of the water channel, respectively, so as to be able to suspend the waterwheel regardless of a width of the water channel,

a holding body which includes a fitting portion that is fitted in a state of actual direct contact with the joining element and has a recess that is not penetrated in order to maintain an end portion of the relevant suspension main body horizontally,

a plurality of footings for horizontally supporting the respective holding bodies outside the water channel, and

a floor plate stretched across upper surfaces of the suspension main bodies.

2. The waterwheel suspending device according to claim 1, wherein a mount portion for fixing the relevant holding body is formed on an anchor portion of each of the footings.

3. The waterwheel suspending device according to claim 1, wherein each of the footings includes a threaded rod provided in an upright manner in an upper surface of the relevant mount portion.

4. The waterwheel suspending device according to claim 2, wherein each of the footings includes a threaded rod provided in an upright manner in an upper surface of the relevant mount portion.
