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 ).

First claim

The invention claimed is:

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.
