Abstract
A flexible dam comprises a resilient waterproof material which holds seawater. An automated inflatable mechanism floats the dam and positions it on the water level. It will generate electrical power with the rise and fall of the ocean tides. The trapped water will channel through a low RPM spiral electric generator. The system will sense the maximum level of the tide and inflate the fabric barrage to the sea level. A sensor on the water exit of the dam will open a sliding gate to the turbine when the desired pressure is reached.
Description
Intellectual Property Office Application No G132019635.8 RTM Date:13 January 2022 The following terms are registered trade marks and should be read as such wherever they occur in this document: Kevlar, Dyneema Intellectual Property Office is an operating name of the Patent Office www.gov.uk/ipo Flexible dam for a small scale renewable tidal energy
Introduction to core idea:
The idea behind this proposal is to use an extremely resilient inflatable fabric which will hold the sea water periodically by automated inflation mechanism.
This system will use the water force which is trapped behind the temporary dam to generate electrical current. Also it will generate a predictable electric power with a natural rise and fall of ocean tides as the cycle continues.
The mentioned fabric will be made of fused layers of Kevlar enforced with Dyneema fibres and coated with hydro gel water repellent material.
The discussed material is made of three layers of multiwall carbon nanotubes which are compressed through an ultrasonic-assisted impregnation deposition method by using a fibre reinforced soft composite technology.
C\I ('Si CO The differences in our design compared to the existing methods: Our tidal energy generator has a massive potential to generate electricity with relatively low cost. (Nj The design can create a good amount of energy with a predictable and manageable outcome.
We believe that our design has a significant advantage to previous attempts and it is much more practical.
1-We are using a strong water proof composite fabric to form a flexible barrier and trap the sea water locally, after sea tide retreats.
2-This flexible fabric automatically floats on top of sea level once the sea tide will reach the maximum level. The operation system has built in sensors which will activate the automated air pressure system.
3-The trapped water will channel through an efficient low RPM spiral electric generator to generate a good amount of electricity in each tidal cycle.
4-The basin is filled through a collapsed fabric barrage until the high tide. Then the system will sense the maximum level of tide and begins to inflate the flexible fabric barrage to the actual sea level.
5-The turbine gates will remain closed until the sea level falls in the other side of the temporary dam in order to create sufficient pressure for the generator.
6-The turbine gates will be opened automatically until all sea water is released.
Summary of component used in this system:
1-Collapsible dam: Our design uses a flexible, folding and thick composite fabric as temporary sea water dam, which can be easily installed and utilised all around the UK costal area.
This collapsible dam will be pinned and installed on the surface of seabed permanently in a specific location with the high tide.
The cost of our collapsible dam is cheaper than the traditional design, maintenance free and corrosion free.
2-Inflatable mechanism: Our design contains an inflatable section on the top of our collapsible dam. This collapsible fabric dam will be floating with the force of air pumped inside the air pocket located on the top of the fabric dam when the sea water riches the maximum tide position.
3-Pressure control system: Sliding gate on the water inlet of the generator will automatically open when C\I the pressure riches maximum desirable force.
C\i 4-Hydroelectric micro turbine generator: Our selected turbine hydraulic generator is a high efficient CO design which is maintenance free and scalable in the UK.
CD
CJ *Our system advantage to other renewable energy (in specific for the UK geographical location)* Our tidal energy design has the potential to fulfil the future electricity demand in the UK.
1-Our system has an advantage to other wind and solar energies as it is more predictable and stable than the others.
2-Among sources of renewable energy, tidal energy has traditionally suffered from relatively high cost and limited availability of sites with sufficiently high tidal ranges or flow velocities. Our system can tackle all of these problems as it is low cost and more scalable.
3-Our system can be installed in many locations around the UK at sea coast easily with a relatively low maintenance involvement
