Abstract

The utility model discloses an electrical generation device floating on water, belonging to electrical generation device field, comprising a plurality of electrical generation units in series or in parallel, wherein each comprises a ship-shaped floating body of which both sides are equipped with at least one group of impellers connected by a spindle, and inside which is equipped with a generator. The generator shaft end is connected with a gear-box output shaft, while the gear-box input shaft is connected with the spindle in a transmission way. The utility model runs preferred in rapid water and is fit for microscopic mobile hydropower plant.

Description

A kind of electricity generating device that swims in the water surface

Technical field

The utility model relates to a kind of electricity generating device, particularly a kind of hydroelectric installation.

Background technique

Hydroelectric installation of the prior art need be provided with check dam at the water surface, carries out retaining, promotes water turbine by waterpower then and rotates, and water turbine drives generator work, sends electric energy, can be by the turbine that the blocks water power supply of being incorporated into the power networks more; The generator set of this water turbine, structure is huge, can only fixedly install, and can not move; Constructing of check dam need be blocked current, influences fish migration, has the potential safety hazard of dam break, easily ecotope constituted harmful effect.

The model utility content

The purpose of this utility model provides a kind of electricity generating device that swims in the water surface, makes its generating the time can swim in the water surface, need not to construct check dam, and can in requisition for and the mobile position.

The purpose of this utility model is achieved in that a kind of electricity generating device that swims in the water surface, the generator unit that comprises some serial or parallel connections, each generator unit comprises into the buoyancy aid of ship shape, the buoyancy aid both sides are provided with at least one group of impeller that is linked to each other by main shaft, be provided with generator in the buoyancy aid, the generator axle head is connected with the output shaft of gearbox, is in transmission connection between the input shaft of gearbox and the main shaft.

During the utility model work, it is fixed on the water surface that water flows with anchor or floating drum with the hawser tractive, maintenance impeller half is under water, and when flow, water promotes impeller and drives the main shaft rotation, and main shaft drives generator through gearbox and rotates, and sends electric energy; Gearbox is used to change output shaft and input shaft rotational speed ratio, can regulate according to different water velocities, to keep the invariablenes turning speed of output shaft, can steadily generate electricity; More this device can be organized and connect and parallel operation, can move freely, and can transport by the towboat pulling mode, need not to build check dam during work, and ecotope is had no adverse effects.The utility model is fit to be arranged in the anxious current of water velocity, is suitable for setting up the miniature movable type water power plant.

For realizing many group generator unit co-generation of power, described generator unit comprises at least two, is connected through crossbeam between the buoyancy aid of two generator units.To organize device by crossbeam more and be connected, each generator unit is linked together in order, be convenient to installation administration and transportation.

Description of drawings

Fig. 1 is the utility model structural representation;

Fig. 2 is that the A of Fig. 1 is to view;

Wherein, 1 impeller, 2 buoyancy aids, 3 crossbeams, 4 generators, 5 gearboxes, 6 main shafts, 7 gears.

Embodiment

As figure, a kind of electricity generating device that swims in the water surface, the generator unit that comprises four groups of parallel connections, each generator unit comprises into the buoyancy aid 2 of ship shape, buoyancy aid 2 both sides are provided with two groups of impellers 1 that linked to each other by main shaft 6, be provided with generator 4 in the buoyancy aid 2, generator 4 axle heads are connected with the output shaft of gearbox 5, are respectively arranged with pitch wheel 7 on the input shaft of gearbox 5 and the main shaft 6; Be connected through crossbeam 3 between the buoyancy aid 2 of adjacent two generator units.

The utility model is not limited to the foregoing description, and described generator unit can be one or more groups, and impeller also can for organizing arbitrarily more; Transmission also is not limited to gear transmission, also can be existing type of belt drive in the prior aries such as belt wheel.
