Owners of many owner-occupied dwellings more often try to use alternative energy sources for power supply to save on electricity. Quite widely the generator units working at most winds are abroad used, but they are very expensive and whimsical in operation. And here if near the territory of your site there is stream, then it is quite possible to build the small hydroelectric power station providing basic needs of economy in electrical energy.
It is required to you
- - sheet iron;
- - metal pipes and corners;
- - generator;
- - steel wire;
- - fastening elements (bolts, nuts);
- - welding machine;
- - tools for work with metal;
- - set of wrenches.
Instruction
1. Prepare tools and materials, necessary for construction of mini-hydroelectric power station. You need sheet iron, steel pipes and metal corners. For turbine wheel prepare the generator of suitable power consisting of brake rotors. Use wheel hub from the old car.
2. Manufacture turbine vanes of steel pipes with a diameter of 4 inches. Optimum, if the number of blades is equal to sixteen.
3. That design wheels precisely corresponded to the nave sizes, make template. On template cut in opening disks, having defined position of sixteen blades. Connect template to one of turbine disks and drill several auxiliary openings (on number of blades). Connect disks among themselves steel rods.
4. Before starting welding of design, purify steel from galvanization. Otherwise galvanized steel will emit toxic gas when welding that can create health hazard.
5. In that part of the turbine which directly will not be connected to the generator cut technology opening with a diameter about 100 mm for convenience of mounting of the generator. The opening will allow to have access to internal part of the turbine.
6. Attach pipe on which to the turbine water will be pumped to the nozzle made of sheet metal plate. Piece of pipe with nozzle fix at an angle 45 degrees to the turbine. The pipe has to move in all directions that will allow to operate water feed system on the turbine.
7. Mount the generator. Make the stator of the generator of wire, having twisted it in nine rings on 125 rounds in everyone. Use at wire routing topology like "star" or "delta". Fasten the stator and the rotor among themselves with fiber glass. For speed control of operation of the generator make three openings in the turbine that will allow to change distance between rotors.
8. Attach the generator to one of sides of the turbine, on the other hand attach the converter of three-phase alternating current in constant, having closed it aluminum casing.
9. Establish the turned-out design at stream, having made separate discharge pipe with a diameter about 4 inches. Attach the generator turbine to pipe. Adjust pipe tilt angle, having achieved that the average speed of rotation of the turbine was not less than 110 RPM that will allow to develop current in 2A.
