Small hydroelectric generator and installation method

Abstract

The invention relates to a small hydroelectric generator and an installation method. Traditionally produced hydroelectric generation devices are generally in an axial-flow type, cement or other materials are needed for building a diversion canal and a vacuum volute chamber before installation, the indirect cost is high, and the project is large; and even though no diversion canal or vacuum volutechamber needs to be additionally built for novel axial-flow type volutes, a large number of accessories are needed, and the cost is high. The small hydroelectric generator comprises a base (1), the upper plane of the base is connected with a transmission system through a bolt, an impeller (8) is installed in the middle below the transmission system, an electric generator (6) is installed above thetransmission system, one side face of the electric generator is provided with a wiring port (7), the side face of the transmission system is provided with a spray head (5), a bent pipe is installed outside the spray head, the bent pipe is fixed to the drive system, and the bent pipe is connected with a transition connector through a flange. The installation method is used for the small hydroelectric generator.

Description

Technical field:

[0001] The invention relates to a small hydraulic generator and an installation method. Background technique:

[0002] The traditional production of hydroelectric power generation devices is generally axial flow, which needs to use cement or other materials to build water diversion channels and vacuum vortex chambers before installation. The indirect cost is relatively high and the project is relatively large. Although the new axial flow volute axial flow type Construct diversion canal and vacuum vortex chamber in addition, but need more fittings, cost is higher. The construction of micro-hydropower stations is to build dams to collect water from small streams in places with a certain head drop, introduce water into hydroelectric generator sets through pipelines, etc., drive water wheels to drive motors to generate electricity, and then supply electricity to consumers through transmission lines.

[0003] In places where there is a relatively high water drop...

Examples

Embodiment 1

[0019] A small hydraulic generator, which consists of: a base 1, the upper plane of the base is connected to the transmission system through bolts, an impeller 8 is installed in the middle part below the transmission system, and a generator is installed above the transmission system 6. One side of the generator has a wiring port 7, and the side of the transmission system is equipped with a nozzle 5, and an elbow is installed outside the nozzle, and the elbow is fixed to the transmission system. The elbow is connected to the transition joint through the flange.

Embodiment 2

[0021] In the small hydraulic generator described in Embodiment 1, one end of the transition joint is fixed to the pressure water pipe 4, the other end of the pressure water pipe is connected to the water source 3, and a water valve switch 2 is installed on one side of the transition joint.

Embodiment 3

[0023] In the small hydraulic generator described in Embodiment 1, the side of the base has a water outlet 9, the pressure water pipe is placed obliquely with the water source and the transmission system, and the pressure water pipe is at an angle of 45 degrees to the ground .
