AI Technical Summary

Technical Problem

The existing turbine bottom ring lacks its own bearing structure, resulting in the lack of further support and reinforcement of the relative rotation of the vortex wheel and the bottom ring, the structural strength is insufficient, and there is room for optimization of the stability and smoothness of the rotation process.

Method used

A cavity is set up in the bottom ring of the turbine, and a plurality of groove rings are added in the cavity to form a ball channel, and a ball is installed to form a bearing structure. The connection between the bearings and the rotors in the bottom ring is achieved by connecting the connecting structures such as channel steel and slots.

Benefits of technology

Through the design of the ball bearing structure, the direct connection between the turbine vortex wheel and the bottom ring is achieved, and the rotation is assisted under the action of the bearing, sharing the stress, improving the rotation smoothness and stability of the rotor, enhancing the structural strength and power generation stability.

Abstract

The utility model relates to the technical field of hydroelectric power generation equipment, in particular to a novel hydraulic turbine set which comprises a bottom ring, a base ring is fixedly welded to the outer side surface of the bottom ring, fixed guide vanes are welded to the top face of the base ring, a top seat ring is arranged above the base ring, and the tops of the fixed guide vanes are fixedly welded to the bottom face of the top seat ring. A foundation ring is fixedly welded to the bottom face of the bottom ring, a movable guide vane bearing hole is formed in the top face of the bottom ring, a limiting cavity is formed in the inner side surface of the bottom ring, and balls are arranged in the limiting cavity. According to the novel hydraulic turbine set, the bearing structure is arranged in the bottom ring, and the bearing in the bottom ring is connected with the rotating wheel through connecting structures such as the connecting channel steel and the inserting groove, so that the vortex rotating wheel of the hydraulic turbine can be in direct butt joint with the bottom ring, auxiliary rotation is achieved under the effect of the bearing, stress sharing of the rotating wheel is achieved, and the bottom ring does not only have the limiting effect any more; the rotating wheel can rotate more smoothly and stably, and the structural strength and the power generation stability are improved.
