Description
Technical field
The utility model relates to a kind of device that water can be converted to mechanical energy.
Background technique
Huge lasting hydraulic energy is being contained in rivers, ocean, and fully developing this renewable continually waterpower resourses is great causes constantly exploring in human several thousand.Along with the tellurian non-renewable resources that the mankind depend on for existence are petered out, it is historical inevitable choice that people seek renewable novel energy.
Summary of the invention
But the purpose of this utility model is to provide a kind of hydrodynamic(al) energy conversion equipment of extended blades, and this device can be converted to mechanical energy with hydrodynamic(al), and conversion efficiency height, simple in structure.
To achieve these goals, the technical solution of the utility model is: but a kind of hydrodynamic(al) of extended blades energy conversion equipment, but it is characterized in that it comprises main shaft 1 extended blades mechanism 4, but be provided with an extended blades mechanism 4 on the main shaft 1 at least;
But extended blades mechanism 4 comprises blade supporting frame 2, blade 3, and blade supporting frame 2 is 2-8, is provided with cavity in the blade supporting frame 2, and blade supporting frame 2 is fixedlyed connected with main shaft 1 (as welding), and 2-8 blade supporting frame is distributed on the main shaft 1; At least be hinged with a blade 3 on each blade supporting frame 2, the height of blade 3 is greater than the cavity height (being that blade can be blocked by the blade supporting frame) of blade supporting frame.
Described blade supporting frame 2 is made up of two support arms, and (constituting cavity between two support arms) arranged in two support arm spaces, and blade 3 is hinged by rotating shaft and two support arms.
Described blade supporting frame 2 is a frame structure.
The beneficial effects of the utility model are:
1, in service, blocked by the blade supporting frame when blade meets water, form bigger area of contact with flowing water, flowing water produces pressure to blade, promote blade movement and drive main axis rotation, thereby rivers, ocean flow kinetic energy are converted to mechanical energy (main shaft is the mechanical energy output shaft); When rotating to backhaul against the current, one end of blade leaves blade supporting frame (the other end of blade and blade supporting frame are hinged) by fluviation, and at this moment the stress surface of blade is parallel with water (flow) direction, and flowing water does not produce pressure to blade basically, so against the current during backhaul, blade stressed very little.
2, the meet water area of stream interface of blade is bigger, and ouput force is big, the conversion efficiency height.
3, can increase blade quantity as required, improve output power.
4, simple in structure, stable and reliable operation.
