Description

1 2427003
RENEWABLE ENERGY POWER UNIT
The present invention relates to a renewal energy power unit and more especially to a fully self-contained, portable and self-erecting and selfdeploying renewable energy power unit.
It is becoming increasingly important to provide portable renewable energy power units that are easy to erect for use in remote areas and to power remote facilities such as cellular telecommunication transmitters, light houses, oil platforms, military installations and scientific research : * stations. S... S...
Several designs of vertical axis wind turbines are known and have been employed to generate electricity. The applicant's earlier patent GB 2286637 discloses a vertical axis wind turbine capable of being mounted on or to an existing industrial chimney, concrete tower or similar structure. 5.5 SS*S
The present invention sets out to provide a portable renewable energy power unit that is fully self-contained, self-erecting and selfdeploying.
According to one aspect there is provided, a portable renewal energy power generation device comprising upper and lower tower sections, the lower tower section including a drive shaft, the upper tower section being telescopically mounted on the drive shaft of lower tower section and including means for producing power from a renewable energy source, whereby vertical movement of the upper tower section with respect to the lower tower section causes deployment and retraction of the power generation means respectively.
Preferably, the power generation means comprises at least one vertically mounted wind turbine blade.
Preferably the or each blade is connected to a hinged rotor arm that is fixed to, and extends outwardly from, the upper tower section.
Preferably still the angle of extension of the or each hinged rotor arm is adjustable through a cable, the ends of which are attached to the hinged rotor arm and the drive shaft of the lower tower section respectively.
Preferably, the lower tower section comprises upper and lower parts, the upper part being tiltable with respect to the lower part.
Preferably, the lower tower section is mounted on an alternator.
:.:::. Preferably still, the alternator is fixedly mounted on a container in which the power generation device can be stowed.
* The invention will now be described by way of example with reference to the accompanying diagrammatic drawings, in which I. * * Figure 1 is a schematic view of a renewable energy power unit constructed in accordance with the present invention; and Figure 2 is a side cross-section view of the renewable energy power unit of Figure 1 in a collapsed state, stored within a container.
Referring first to the Figure 1, the renewable energy power unit 2 comprises lower and upper tower housing sections denoted 4 and 6 respectively. The lower tower housing 4 is mounted via bearings 8 on direct drive slow speed alternator 10 which in turn is fixed to the base of a container 12 in which the power unit 2 can stored and transported (see later reference to Figure 2).
The lower tower housing 4 has a drive shaft 14 extending longitudinally through its centre. The drive shaft 14 is connected at its lower end to the alternator 10.
The lower tower housing 4 has a base part 16 and main part 18.
The main part 18 is tiltable in respect of the base part 16 via a hinged flange 20. The hinged flange 20 enables the main part 18 of lower tower housing 4 to be tilted so as to be generally perpendicular to the base part 16 to thereby allow the entire lower tower housing 4 to be stowed within the constraints of the container 12.
A sliding splined flexi coupler 22 is provided to connect and disconnect the base and main drive shaft parts of the lower tower housing 4 when the base 16 and main parts 18 of the lower tower housing 4 are ::. tilted in respect of each other. S... * * * .**
The upper tower housing 6 of the power unit 2 includes a hollow S....
* S torque tube 24. Wind turbine blades 26 are mounted at the head 28 of the upper tower housing 6. S. * S * SI.
An example of the configuration and design of the wind turbine S...
blades 26 is disclosed in the Applicant's earlier application GB0416077.6 which is incorporated herein by reference.
The torque tube 24 of the upper tower housing 6 is mounted on the drive shaft 14 of the lower tower housing 4 via a splined bush or sleeve which enables the torque tube 24 to move freely along the drive shaft 14 whilst the upper tower housing 6 is hoisted into position during erection of the power unit 2.
During erection, the foot of the torque tube 24 is lifted upwardly along the drive shaft by cables 32 extending between four electrical winches 34 (only two of which are shown) mounted on each corner of the container 12 and the foot of the torque tube 24, via pulleys 36. Once erected the cables 32 act as a guide wire system for the power unit 2.
An inwardly tapering concentric waterproof seal 38 is provided at the top of the lower tower housing 4 to prevent water or moisture from entering a gap which would otherwise be formed at the intersection of the upper and lower tower housings 6, 4.
The wind turbine blades 26 are vertically mounted around the head 28 of the upper tower housing 6 via hinged rotor arms 40. Cables 42 extend from the blades 26 to the head 28 of the upper tower housing 6, and then down through the torque tube 24 via pulleys 44 to be eventually anchored to the drive shaft 14 of the lower tower housing 4.
As the upper tower section 6 is raised during erection, the cables undergo tension thereby raising the hinged rotor arms 40 and blades 26 ::. to a desired configuration. S... * * S...
During use, the entire tower head 28, torque tube 24, blade-raising S.....
* : cables 42 rotate with the blades 26 on a bearing 46 at the tower head 28.
S..... * S
:. The alternator 8 is a directly coupled self-starting slow speed alternator which is able to govern its power output automatically depending on the power input received from the turbine blades 26, or the prevailing wind speed. The ground sited unit of simple design will not begin to generate power until the wind turbine blades 26 are rotating at a desired speed. The generation load of the alternator then increases as the wind speed/blade rotation speed increases. If the wind speed/blade rotation speed reduces the alternator will automatically decrease its generation load. Consequently, the alternator 8 can be considered as entirely self-governing.
Preferably, but not essentially, the alternator unit would be achieve self-governing automation through mechanical mechanisms, without the need for power conditioning electronics.
Figure 2 shows the power unit 2 in its collapsed state for storage and transportation. In this state, the main part 18 of the lower tower housing 4 is tilted so to be perpendicular to the base part 16 of the lower tower housing 4 and the actuator 8. The torque tube 24 of the upper tower housing 6 is housed around the drive shaft 14 of the lower tower housing 4 and the rotor arms 40 are hinged towards the tower head 28 such the blades 26 to minimise the gap between the blades 16 and the tower head 28.
In this state, the entire power unit 2 can be stowed within a standard shipping container.
The power unit 2 may alternatively, or additionally, include solar panels for power generation. * S. * . * I...
*.... The power unit 2 would be accompanied a suitable power source, S 151 for example, a diesel or bio-diesel generator, battery storage, an inverter I..,..
* : and a control panel.
*lSSSS * S Once deployed it is envisaged that the power unit 2 would run automatically. The battery charge would be automatically maintained by using the power generated by the wind turbine or solar panels which provide the required power to the battery storage via the inverter. The generator would be available to start the unit in the absence of wind or sun for an extended period of time.
Once the unit has been transported to the desired location, and the container opened, and the entire unit can be erected and deployed by a single person using the control panel, which may be controlled remotely.
The above described embodiment has been given by way of example only, and the skilled reader will naturally appreciate that many variations could be made thereto without departing from the scope of the present invention.
