Micro-hydro for work in conditions of calm water.
Developed micro-hydro power plants that can generate more power at small velocities, in quiet water, i.e. lake, pond, Bay, etc. – from 0.4 m/s.
The technology is awaiting funding!
Description:
Developed micro-hydro power plants that can generate more power at small velocities, in quiet water, i.e. lake, pond, Bay, etc. – from 0.4 m/s.
Data micro-hydro power is represented by the following types:
– Bertomeu micro-hydro,
– semchinovo micro-hydro.
Design micro-hydro is simple. The main shaft of the micro-HPP with the attached screw rotates at a certain constant speed by a low power motor-reducer rotates the propeller, which, in turn, is connected to a generator. End power much more than it consumes the drive.
As most lowland rivers have poor over – 0,4-0,6 m/s, then increase the speed to the desired section of the river developed boosters flow, which can speed it up to 30-300%. Accordingly, the capacity of micro-hydropower to increase exponentially. Flow boosters in the form of a simple, but sufficient clearance, you can install them temporarily and some permanently.
Advantages:
– high output power at small velocities from 0.4 m/s and more
– works on almost any flat rivers
– able to generate electricity in conditions of quiet water,
– the possibility of rotation of various types of machines and equipment without the use of electricity. For example, to pump water from the river with a capacity of several tens of liters to 3 m3/hour, pressure can reach 2 atmospheres, to rotate the grinder, drilling machine, concrete mixer, crusher, mini–sawmill, wood – and metal-processing machines with a maximum capacity of 10 kW, under appropriate operating conditions. The efficiency of this drive in 2 – 3 times higher than the use of power tools, and safe
– high efficiency – up to 70%
– low weight – 12 kg
– low manufacturing cost,
– ability to work all year round: winter and summer. Design of micro-hydropower station adapted for operation in winter directly beneath the ice. Developed special tooling that allows to operate in temperatures down to-40C.
Vertina micro-hydro:
Vertina micro-hydro is designed for use in rivers with a quiet current of 0.6-1.0 m/s.
Produces 1.0 kW/m 2 the net power at a flow velocity of 0.7 m/s Weight without generator and gear 12 kg. efficiency up to 70%. 90 – 100 rpm at idle speeds. The maximum power of 30.0 kW. Works fine in stagnant water with a removable module. Changing the number of partitions can be adjusted output power in a wide range. The speed change main shaft speed.
Semchinova micro-hydro:
Semchinova micro-hydro is designed to operate in medium speed of the river is 1.0 – 2.0 m/s.
Is a new kind of screw and unlike traditional has a higher momentum of 1.5 – 2.5 times, depending on the speed of the current. An efficiency of 50-60%. Outputs of 1.5 kW/m2 of pure power at a flow velocity of 1,0 m/s Maximum capacity up to 8.0 kW. Works fine in stagnant water with a removable module. Power changes only when you increase the diameter of the screw or the speed of the water. The speed change main shaft speed.
