Abstract
Abstract This invention relates to a mounting structure for a tubular turbine having a horizontal or slightly inclined machine axis, particularly a Kaplan-type tubular turbine, and whose supporting forces act at a right angle to the duct wall of said turbine, on one hand, and parallel to said duct wall, on the other hand, and are absorbed by supporting plates equipped with foundation anchors in said duct wall, comprising a knife-edge suspension means connected to said turbine housing and in engagement with one of said supporting plates, and adapted to lead that portion of said supporting forces acting at a right angle to said duct wall into a foundation, and elastic member means connected to said supporting plate and to a support for said suspension means, and adapted to absorb that portion of said supporting forces acting parallel to said duct wall.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
137 words
A mounting structure for a tubular turbine having a horizontal or slightly inclined machine axis, particularly a Kaplan-type tubular turbine, and whose supporting forces act at a right angle to the duct wall of said turbine, on one hand, and parallel to said duct wall, on the other hand, and are absorbed by supporting plates equipped with foundation anchors in said duct wall, comprising a knife-edge suspension means connected to said turbine housing and in engagement with one of said supporting plates, and adapted to lead that portion of said supporting forces acting at a right angle to said duct wall into a foundation, and elastic member means connected to said supporting plate and to a support for said suspension means, and adapted to absorb that portion of said supporting forces acting parallel to said duct wall.
Claim 2
Dependent Claim
137 words
A mounting structure for a tubular turbine having a horizontal or slightly inclined machine axis, particularly a Kaplan-type tubular turbine, and whose supporting forces act at a right angle to the duct wall of said turbine, on one hand, and parallel to said duct wall, on the other hand, and are absorbed by supporting plates equipped with foundation anchors in said duct wall, comprising a knife-edge suspension means connected to said turbine housing and in engagement with one of said supporting plates, and adapted to lead that portion of said supporting forces acting at a right angle to said duct wall into a foundation, and elastic member means connected to said supporting plate and to a support for said suspension means, and adapted to absorb that portion of said supporting forces acting parallel to said duct wall.
Claim 3
Dependent Claim
23 words
A mounting structure according to claim 1 wherein the elastic member means is a thin plate which permits deformation by virtue of elasticity.
Claim 4
Dependent Claim
39 words
A mounting structure according to claim 1 including passage tube means connected to said turbine housing and to a supporting plate, whereby that portion of the supporting forces acting parallel to the duct wall is transmitted into the foundation.
Claim 5
Dependent Claim
32 words
A mounting structure according to claim 3 including a rubber suspension between said passage tube means and said supporting plate, said suspension serving as an elastic member and also as a seal.
Claim 6
Dependent Claim
16 words
A mounting structure according to claim 1 including tie rod means connected to said supporting plate.
