Description
Technical field
The utility model relates to a kind of hydroelectric generator, especially relates to the hydroelectric generator that a kind of pressure flow that utilizes water pipe directly drives generating.
Background technique
Utilize the pressure flow of water pipe directly to drive the hydroelectric generator of generating, existing relevant report, but have some problems: complicated as structure, assembling inconvenience; Seal point is many, and sealing reliability is not high; Pressure flow does not form the jet impulse impeller, and is limited to the impact force of impeller, and the angle of water impact impeller is undesirable, causes the water flow dynamic energy loss big, and mechanical efficiency is low.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to assembly, sealing reliability is high, the current mechanical efficiency is high built-in hydroelectric generator.
The utility model is provided with body, impeller, rotor, stator, rotating shaft and circuit board; Body is provided with intake tunnel, exhalant canal, impeller cavity and enclosed cavity, and intake tunnel is communicated with exhalant canal through impeller cavity, and intake tunnel is communicated with by jet hole with impeller cavity, and enclosed cavity and intake tunnel, exhalant canal and impeller cavity are isolated; Impeller is arranged in impeller cavity and is located in the rotating shaft; Rotor, stator and circuit board are located in the enclosed cavity, and rotor is located in the rotating shaft; One end of rotating shaft is positioned at enclosed cavity, and the other end of rotating shaft is positioned at impeller cavity; Circuit board is provided with the lead that is connected with rotor or stator and draws lead.
Body is preferably tubular body, and the two ends of body are respectively equipped with water supply connector and water output connector.
The shaft axis of the shaft axis of intake tunnel, the shaft axis of exhalant canal, impeller cavity and the shaft axis of enclosed cavity overlap.
Rotor is preferably coil rotor, and stator is preferably the magnet ring stator.
Be provided with annular gap between rotor and the stator.
Enclosed cavity is provided with end cap, and enclosed cavity is provided with waterproof ring.
The water outlet port of jet hole is preferably vertical with rotating shaft.
Because body of the present utility model can be combined by the water supply connector at two ends and water output connector and tubular body, enclosed cavity also can be combined by end cap and tubular body.Very convenient when therefore assembling inner components.Because only need at an end of the enclosed cavity hydrosphere of setting up defences, so seal point is few, sealing reliability improves.Owing to be provided with jet hole, therefore the current that penetrate from jet hole rush at impeller, can strengthen water flow impact pressure greatly; Again because the water outlet port of rotating shaft and jet hole can be vertical, and then current can vertically rush at the blade of impeller, make impeller obtain the most effective rotational energy, the energy of flow of can not wasting water, so current efficient the significantly improving of doing work, thus improve generating efficiency greatly.
