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...
