Embodiment 1

[0014] Such as Figure 1-2 As shown, a device for generating electricity by using naturally flowing river water includes two parallel floating platforms 1, a blade runner 2 is arranged between the two floating platforms, and a main shaft 3 is arranged at the center of the blade runner 2, and on the floating platform There is a bearing 4 for supporting the main shaft, the main shaft is connected to the generator 6 through a transmission mechanism, the transmission mechanism also includes a transmission 5, the upstream ends of the opposite surfaces of the two floating platforms are in the shape of an inverted "eight", and the blades on the blade runners The water-facing surface of 7 is arc-shaped.

[0015] During use, the floating platform of this device is installed on the river surface that has flowing water, promotes the rotation of blade runner 2 and main shaft 3 by flowing water, then drives speed changer 5 and generator 6 to work, generates electricity by generator.

Embodiment 2

[0017] Such as image 3 As shown, the device is provided with three juxtaposed buoyant platforms, blade runners 2 are arranged between adjacent two buoyant platforms, the center of the blade runners 2 is provided with a main shaft 3, a generator 6 is arranged on the middle buoyant platform, and two The main shafts of the blade runners are respectively connected to the generator on the intermediate floating platform through the transmission mechanism; the generator is driven by the rotation of the two blade runners and the main shaft to generate electricity.

Embodiment 3

[0019] Such as Figure 4 As shown, the device is provided with three juxtaposed floating platforms, a blade runner 2 is arranged between two adjacent floating platforms, a main shaft 3 is arranged at the center of the blade runner 2, a generator is arranged on the middle floating platform, and two blade runners The main shaft of the runner is connected to the stator and rotor of the generator through the transmission mechanism, and the main shaft connected to the stator of the generator is reversed through the gear, so that the stator and the rotor rotate in the opposite direction to increase the speed of the generator. The rotation of the wheel and the main shaft drives the generator to generate electricity, thereby improving the power generation efficiency.

Abstract

The invention discloses a device for generating power by using naturally flowing river water. The device comprises at least two abreast floating platforms, wherein a blade runner is arranged between every two adjacent floating platforms; a main shaft is arranged at the center of the blade runner; bearings for supporting the main shaft are arranged on the floating platforms; the main shaft is also connected to a speed reducer and a power generator; the main shaft rotates to drive the power generator to generate power; the upstream ends of opposite surfaces of the adjacent floating platforms are inversely splayed, so that the speed of water flow in a blade runner region can be increased; the upstream faces of blades on the blade runner are cambered, so that the water flow can be easily concentrated into cambered slots in the blades when being in contact with the blades, and the kinetic energy and the potential energy of water can be converted into electric energy to the maximum extent. The device disclosed by the invention is simple in structure, smaller in investment and easy to implement, and is very suitable for power generation on a small-size river; furthermore, a water retaining dam is not needed, so that the surrounding ecological environment cannot be affected.

Description

technical field [0001] The invention relates to a device for generating electricity by utilizing naturally flowing river water. Background technique [0002] The basic principle of hydroelectric power generation is to use the water level drop to cooperate with the hydroelectric generator to generate electricity, that is, to use the potential energy of the water to convert the mechanical energy of the waterwheel, and then use the mechanical energy to drive the generator to obtain electricity. At present, hydroelectric power generation mostly adopts construction of dams upstream of rivers to increase water level drop for power generation. This method is suitable for medium and large rivers, and its cost is high, so its application is limited. Contents of the invention [0003] The object of the present invention is to provide a device for generating electricity by using naturally flowing river water, which can be used to generate electricity by installing the device on a riv...
