Portable hydroelectric generator unit
First Claim
1. a portable hydroelectric generator set comprising:
- (a) a hydraulically multi-jet Pelton type turbine including;
(i) a body having a water inlet for connection to a source of water under pressure and a water discharge conduit;
(ii) a turbine wheel being mounted on a shaft and rotating in air within said body, said turbine wheel having a plurality of blades;
(iii) an annular distribution chamber located within said body and being arranged substantially coaxially with said turbine wheel, said annular distribution chamber being in communication with said water inlet, said annular distribution chamber having a wall, said wall having a plurality of openings facing said turbine wheel;
(iv) a flow control valve in said water inlet for controlling the water flow rate entering said turbine;
(v) a plurality of injectors, each injector comprising a tubular member fitted into one of said plurality of openings and having an open end to generate a water jet directed onto said blades of said turbine wheel;
(b) an electric generator having a shaft connected to said turbine wheel; and
(c) an output power regulating device comprising an electronic regulator electrically connected to a power output of said generator set and electric actuating means adapted to control said flow control valve.

Abstract
The generator unit is driven by a small Pelton turbine (10) having a plurality of injectors (11) each comprised of a single tubular part connected to a ring-shaped distribution chamber. The turbine wheel drives a multiphase synchronous generator (20) having permanent magnets. The alternating voltages produced by the generator are rectified in order to obtain a direct voltage of 24 V. The water flow rate is regulated at the input of the turbine by means of a regulation valve (13) controlled by an electronic regulation unit (23), to automatically control the power of the generator unit as a function of the output voltage variations. Said portable generator unit, which is extremely simple and reliable may be provisionally or permanently used wherever a pressure water connection is available.
