Abstract

Trying to save nature and people from pollution and help regenerating nature since using it, power is inexpensive.
Also the current from these devices can be used to extract hydrogen and oxygen (by electrolysis) from water and the extracted hydrogen is a valuable motor-fuel.

Description

    DETAILED DESCRIPTION OF THE INVENTION
  • The system is made up of 3 main parts:
      • 1st unit: a V shaped unit that has a pipe like end with edges (of the V shape) higher than the fluid surface at its highest point. (ex. If used in rivers, the V shaped unit must have its edges higher than the river surface during flood period). (FIG. 1, 2, 3)
  • At the end of the first unit, a collector connects it the second unit.
      • 2nd unit: it consists of snail shaped pipes in which the fluid coming from the first unit is accelerated again in these pipes. The acceleration is due to physical fact that the fluid running in the first ring of the snail shaped pipe runs faster in the second smaller diameter ring and faster in the third smaller ring of the pipe and so on. We also have the ability to widen and tighten rings (the 1st is wider than the 2nd, and the 3rd is tighter then the 2nd . . . ) makes also a potential difference at both ends of each pipe. (FIG. 4)
  • The fluid accelerated by the 1st and 2nd unit plus the fluid from the fluid flow enters the 3rd and last unit.
      • 3rd unit: the 3rd unit which is also a snail shaped housing system.
  • In each ring of the snail shaped housing system sits a turbine of different diameter going from the greater diameter turbine to the smaller diameter turbine (FIG. 5).
  • How it works: the 1st turbine's job is to collect as much fluid possible from the fluid stream and the 2nd unit (FIG. 17). The fluid is enclosed in the 1st ring (FIG. 10). A big opening on the top of the 1st ring, connecting the 1st ring to the 2nd ring (ex. Via twisted pipe toward 2nd ring) (FIG. 9) lets most of the fluid captured by the 1st turbine escape to the 2nd ring (FIG. 6). Since the 2nd ring is smaller in diameter than the 1st ring, the fluid coming from the flow having the velocity of the stream travels in the 1st ring with velocity of the stream and faster in the 2nd ring, faster in the 3rd ring, faster in the 4th ring and so on . . . (FIG. 7, 7 a) by this, turbine sitting in 2nd ring turns faster than the one in 1st ring and the one in 3rd ring turns faster than the one in the 2nd and so on . . . In fact the perimeter of the 1st ring is 2πr1, the perimeter of the 2nd ring is 2πr2, the perimeter of the 3rd ring is 2πr3 . . . where r1>r2>r3 are radius of respectively 1st ring, 2nd ring, 3rd ring . . .
  • The turbines can also differ in width from one another going from the wider to the thinner turbines (FIG. 8). The number of rings in the snail shaped housing unit of the 3rd unit is made upon consideration of the speed of the fluid flow during different period of time. For ex. In riverbeds the consideration is due mainly following seasons. Because rivers are slower in summer and early autumn, the number of rings is considered due to the water speed in these periods.
  • Each turbine in the 3rd unit has a star shaped center (FIG. 11). A horizontal axis with also a horizontal star shaped end can be fixed to any turbine depending on the R.P.M. generated by the turbine at anytime of the year (FIG. 13). In order to do that the 1st ring in the 3rd unit that has a door at the opening of it will be shut down not letting any fluid to pass through it and so the turbines stop turning allowing the operation to be done (FIG. 8).
  • The other end of the axis is connected to a wheel (FIG. 14). This wheel is connected to another smaller wheel by the mean of a clutch. The smaller wheel turns the dynamo or alternator or whatever mechanical electrical device. The wheels and the dynamo or alternator will be placed on dry land (FIG. 15).
  • Hence the horizontal axis is moved horizontally to be fixed at the needed turbine maybe once every 2 months if the device is used in a river for example (FIG. 16).
  • Maybe a system consisting of 5 or 6 even more snail shaped rings (going from greater to smaller diameter and width rings) should be considered to slow running rivers.
  • Also the number of rings and their width (potential difference) should be considered in the 2nd snail shaped pipe unit. The slower the fluid is at low periods, the greater the number of pipes should be considered.
  • Construction:
  • Construction on rivers and streams:
  • The fluid flow (or river) is diverted in the area where the machine should be installed. One way of doing so is by placing sand bags piles in a square form. The water inside the square of sand pile is sucked by means of water pumps. A whole is dig inside the square. The depth of the hole is also considered by fluid velocity of the stream usually ranging from 50 cm to 1 m depth hole.
  • The 1st unit sits on top of the hole, the 2nd unit benefits from the depth of the hole by gravity means and potential difference at its end and so the 2nd unit (snail shaped pipes) is oblique at approximately 45° angle to the 1st turbine of the 3rd unit. The 1st ring of the 3rd unit sits in the hole (FIG. 17).
  • This way the fluid enters the 3rd unit by 2 means, the fluid accelerated by the 2nd unit and the fluid from the fluid flow (of course all units should be well fixed to the fluid bed to resist the strong fluid flow. One cheap way of doing so is to make the 1st and 3rd units using concrete and the system can be covered with plants if used in rivers for beauty purpose).
  • If the stream fluid is very slow, a good way of investing this system is to dig a deep hole in the ground and plant the system vertically in it so the fluid is more accelerated by gravity. The exit of the fluid from the last ring could be made by an underground oblique pipe to the bed of the river allowing the fluid to exit into the stream (FIG. 22). This way the axis fixed to the turbine is vertical to the stream and a differential is needed to convert the rotation of the vertical axis to a horizontal one, a horizontal axis fixed to the differential now turns the wheels and the dynamo or alternator.
  • In wind driven devices the 1st unit (V shaped) is funnel shape, in the 3rd unit the opening of the 1st ring is closed with openings only to the pipes of the 2nd unit (FIG. 20).

Claims (3)

1. This device is meant to increase fluid velocity streams (ex. Rivers, winds, sewage system of a city) in order to get “high” R.P.M. from the end or the middle of the device. The “high” R.P.M. (rotation per minute) is needed since most commercial dynamos and alternators require 1500 R.P.M. to 3000 R.P.M. usually to supply good frequency and voltage electric current.
2. With this device we're creating a potential difference in a fluid at both ends of the machine without the need of making leveling (water damns . . . ) in the bed of the streams and thus changing the environment of the precious wild life in it.
3. Small changes on the device but not changing the design nor the order of the unit consisting it are made to make it run on wind (FIG. 20).
This device can be fixed on the top of the wind mills (eolienne) and thus benefiting of the gyroscopic movement the eolienne has and the wind coming from the big helix of the eolienne. (FIG. 21)
The torque generated by the device can be added to the mechanical electrical device of the eolienne giving a boost to the electrical current from it.
Benefits:
This device uses only a small segment of the fluid flow bed and thus constructing several devices on the fluid flow doesn't alter the flow of the fluid nor the environment (ecosystem) that lives in it. (FIG. 18)
We can make a chain of devices connecting each one to another on a fluid flow stream and so getting more power from one unit to another, so the power of the chain can grow exponentially. (FIG. 19)
