The rotational water turbine is reasonable in design and skillful in design and utilizes a rotational water wheel of a mechanical concave water wheel, energy conversion is higher along with increasing of energy of water on a contact surface inside the groove, water applies work inside the rotational main wheel of the concave water wheel, the waterproof plates are stressed simultaneously, and water flow is drained from spaced water holes.
Description
Technical field
The utility model relates to a kind of hydropower generating device, refers in particular to water turbine, is specially the rotary hydroturbine that has concave type wheel.
Background technique
The kind of existing water turbine is a lot, impact is arranged, mixed-flow, axial flow, tubular, the pumped storage water pump type, tilt-impulse type etc., yet, these water turbine are complex structure on the one hand, utilization ratio to water is not high on the other hand, all be to utilize flow energy to do work merely, the patent No. is that the structure that 03211944.5 name is called the disclosed water turbine of patent document of pipe flowing pressure water turbine comprises casing, be located at the water intake of casing one upper lateral part, be located at the water outlet of casing opposite side bottom, be located in the casing, the middle part has two ends and stretches out casing outer axis body, the wheel wall is provided with the main wheel of rotary piece, rotary piece is a blade, though the water turbine of this structure is simple in structure, still is to utilize flow energy to do work merely, if, be the working efficiency that is difficult to improve water turbine so do not change the structure of water turbine.
Summary of the invention
The utility model provides a kind of rotary hydroturbine that has the matrix water wheels in order further to improve the working efficiency of water turbine.
For this realizes above-mentioned purpose, the utility model has adopted following technological scheme: a kind of rotary hydroturbine that has the matrix water wheels, comprise casing, casing divides three parts: front housing, middle casing, back cabinet, the one side upper end of middle casing is a water intake, fluted in the middle casing, one side lower end of front housing and back cabinet is connected with water outlet, the inner face of front housing and back cabinet is provided with drain groove, being located at central part in the casing has end that axis body stretches out the two side ends of the matrix water wheels rotary type main wheel the casing two ends outside and is provided with water resistant plate in taking turns, the angle of water resistant plate is for leaning forward from left to right, the angle of water resistant plate is hypsokinesis from left to right, the lower end of water resistant plate is fixing with wheel, water resistant plate being distributed on the circumferential body at interval, and the gap of water resistant plate is a water flow hole, water resistant plate upper end and circle body internal fixation, the bottom portion of groove of wheel is provided with fixedly water resistant plate, and the water resistant plate another side is oblique profile, on the water resistant plate circumferential surface that is distributed in bottom portion of groove at interval.The utility model is reasonable in design, be skillfully constructed, the rotary type water wheels of mechanical matrix water wheels have been utilized, the energy of water surface of contact in groove increases, and transformation of energy is just big more, and water does work in matrix water wheels rotary type main wheel, water resistant plate is simultaneously stressed, therefore water hole current drainage at interval increases the transmission energy of current, has improved the working efficiency of the water turbine of matrix water wheels greatly.
