Abstract

The utility model discloses a water channel hydroelectric generating device comprising an electrical generator and a support. An impeller shaft is connected with the support in a rotatable manner. Impellers are fixedly connected with the impeller shaft. Impeller blades are fixedly connected with the impellers. The shape of the impeller blades matches with the shape of a trapezoidal channel. A first gear is fixedly connected with one end of the impeller shaft, and is meshed with a second gear which is fixedly connected with a rotor shaft of the electrical generator. The rotor shaft is connected with the electrical generator. The water channel hydroelectric generating device is simple in structure and reasonable in design; the shape of the impeller blades matches with the shape of the trapezoidal channel, so that impulse force of water on the impeller blades is increased, and kinetic energy is increased; and the first gear on the impeller shaft is meshed with the second gear and a third gear, so that kinetic energy on the rotor shaft of the electrical generator is effectively increased.

Description

A kind of water channel road hydroelectric installation

Technical field

The utility model relates to the power generation system technical field, relates in particular to a kind of water channel road hydroelectric installation.

Background technique

In existing technology, hydroelectric power system all is to have utilized water-head, and kinetic energy and potential energy that the current of upstream water level when the downstream produces change into electric energy.In the generating of existing water channel road, the wheel blade on the impeller is rectangle all, and the water channel road is trapezoidal, and wheel blade shape and water channel road shape do not match, and the water slug in the water channel road has been lost a part of potential energy on wheel blade like this.

Summary of the invention

At the problem that above-mentioned prior art exists, the utility model provides a kind of water channel road hydroelectric installation.

To achieve these goals, the technical solution adopted in the utility model is: a kind of water channel road hydroelectric installation, comprise generator and support, impeller shaft rotatably is connected on the support, impeller is fixedly connected on the impeller shaft, be fixedly connected with wheel blade on the impeller, wheel blade shape and trapezoidal channel form fit; One end of impeller shaft is fixedly connected with first gear, first gear and the engagement of second gear, and second gear is fixedly connected on the generator rotor shaft, and generator rotor shaft is connected with generator.

As preferably, also comprise the 3rd gear, the 3rd gear is arranged on an other side of first gear and meshes with first gear, and the 3rd gear is fixedly connected on the 3rd generator rotor shaft, and the 3rd generator rotor shaft is connected with the 3rd generator.

As preferably, described generator is clockwise generator, and the 3rd generator is counterclockwise generator.

Compared with prior art, advantage of the present utility model is: wheel blade shape and trapezoidal channel form fit, increased the impact force of water to wheel blade like this, and increased kinetic energy; First gear on the impeller shaft respectively with the engagement of second gear and the 3rd gear, effectively like this increased the kinetic energy on the generator rotor shaft.
