Description
Technical field
The utility model relates to the device that a kind of river that utilizes natural flow is generated electricity.
Background technique
Hydroelectric basic principle is to utilize the height of water, and the hydrous water turbine generator produces electric power, namely utilizes the potential energy of water to transfer the mechanical energy of water wheels to, then with the mechanical energy pushing generator, and obtain electric power.Adopt that utilize water for producing electric power at present built check dam more in upstream, river, increase the height of water and generated electricity, and this method is applicable to medium-and-large-sized river, and cost is higher, and application is restricted.
Summary of the invention
The device that the purpose of this utility model provides a kind of river that utilizes natural flow to be generated electricity, by this device is installed can be generated electricity having on the river surface of flowing water, simple in structure, cost is lower.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: the device that a kind of river that utilizes natural flow is generated electricity, comprise at least two floating platforms arranged side by side, be provided with blade rotary wheel between adjacent two floating platforms, the center of blade rotary wheel is provided with main shaft, floating platform is provided with the bearing for supporting spindle, main shaft is connected to generator by driving mechanism, described driving mechanism also comprises speed changer, the upstream extremity of described adjacent floating platform forward surface is inverted "eight" shape, and the upstream face of the blade on blade rotary wheel is curved.
Preferably, this device is provided with two floating platforms arranged side by side, is equipped with bearing, speed changer and generator on two floating platforms.
Preferably, this device is provided with three floating platforms arranged side by side, between adjacent two floating platforms, is provided with blade rotary wheel, and middle floating platform is provided with generator, and the main shaft of two blade rotary wheels all is connected on the speed changer of driving mechanism respectively, then by speed changer, is connected to generator.Rotation drive generator by two blade rotary wheels and main shaft is generated electricity.Preferably, this device is provided with three floating platforms arranged side by side, be provided with blade rotary wheel between adjacent two floating platforms, middle floating platform is provided with generator, the main shaft of two blade rotary wheels is connected with rotor with the stator of generator by driving mechanism respectively, wherein the sense of rotation of the stator of generator and rotor is contrary, to improve the rotating speed of generator, and then promotes generating efficiency.
The utility model, because the upstream extremity by adjacent floating platform forward surface is set as inverted "eight" shape, can increase the water velocity in blade rotary wheel zone, makes the rotational velocity of blade rotary wheel accelerate, and improves generating efficiency; Simultaneously, the upstream face of the blade on blade rotary wheel is set to arc, while making current contact blade, be easy to focus in the curve bath of blade, and by the kinetic energy of water and potential energy converting and energy, be electric energy to greatest extent.Of the present utility model simple in structure, drop into lower, easy to implement; Be highly suitable on small rivers and generated electricity, in addition owing to not needing to arrange check dam, the ecotope around also can not affecting.
