Abstract

An adjustable height wind turbine 1 which automatically ascents and retracts from a restricted daytime height or ground to achieve a required safe height for purpose of operation during the night. This system may be powered by solar panels 15 and standby battery storage. Height sensors and timers are used to determine appropriate descent times including in restricted areas. A hydraulic lift pump may be used to lower and raise the masts. The masts may automatically descend when there is a systems failure or a need for maintenance. The system is intended to reduce noise and visual pollution during the day.

Description

Retractable / 7 24 wind turbine support column
Field of invention
The present invention refers to a unique retractable wind turbine support column that enables optimum height . to be achieved during night hours in urban areas especially where such height if maintained during daytime . could be perceived as an eyesore to neighbours
5. It also allows a fully automatic mast system for other devices
Background
In recent years with the advent of alternative renewable power supplies wind turbines have come into fashion
However most are attached to optimum fixed height masts varying from 6 to 8 metres and operate 24/7 that is during daylight and night time hours These are often free to run and quite noisy and often obtrusive 10. to neighbours
These are normally installed in rural areas where they are considered not to be overly intrusive
However in urban areas it is often difficult to install at the height previously described due to planning restrictions or where neighbours object where they are visible or too noisy
Although they may be demountable especially for maintenance none at present incorporate a means to extend
15. the height automatically to an optimum from a mean support height of some 3 metres or so
Now in urban areas the present invention outlines the means of overcoming these limitations so that quiet running 42- 45 dBa wind turbines can be more readily located in urban areas
And at an optimum height without flouting planning laws and at the same time avoiding visual impact objections . from neighbours.
2O.This can be done by raising the wind turbine support column from 3 mor so base day time height to an optimum 6 metres or so during the night hours
At this height the wind turbine can benefit from the prevailing wind and operate towards maximum speed
Summary of invention
The invention covers primarily the application of the means of supporting wind turbines to allow them to ...
25. operate optionally at two selected heights suited to the available wind speed during day time and night hours
It is intended where a greater height is available to achieve a wind speed required to operate the wind turbine at maximum output that the support arrangement is automatically extendable and retractable
It is also intended to have the wind turbine at an accessible height of some three metres for safe height and operation during daylight hours Also when not operational for easier repair and maintenance
This lower level of operation ensures the wind turbine conforms to most height restrictions in urban areas and is reasonably unobtrusive
Equally by being able to raise the turbine to an optimum wind speed height during the night hour's maximum power supply to the owner's property or battery storage facility or to both can be achieved
The current invention includes various important components such as those outlined as follows :35 . A base column some 3.0 m high incorporating a secondary column of smaller diameter that can be raised by hydraulic or compressed air means
This requires a motorised rather than hand pumped lifting device
To enable this action it is optionally powered by a day light solar panel of adequate size so as to lower the secondary column at daylight and surplus power is stored in an LV UPS/ Battery
1.
Retractable / 7 24 wind turbine support column
Summary of invention . This enables the secondary column to be raised at dusk and allow the wind turbine to operate at an optimum height of some 6 metres during night time
This enables the secondary column to be raised at dusk and allow the wind turbine to operate at an optimum height of some 6 metres during night time
In conjunction with the above the battery pack provides power to ancillary components that provide a means for safe operation of the support column when either ascending or retracting and these are outlined below
The wind turbine is automatically switched off at daily commencement of ascent and switched on once the set height is achieved and conversely on timed descent upon dawn
Once at a height of some 6 metres a locking device clamps both the support column and tie rods and is realised on start of support column descent
And optionally for use with a vertical wind turbine an anti-torque device begins to counter any excessive twisting affect a vertical wind turbine might have on the locked tie rods
The daily descent of the support column is optionally caused by the opening of a valve releasing hydraulic fluid in to a dump vessel or release of compressed air to atmosphere and the speed of descent can optionally be controlled
All of the above utilises a DC to LV Power control and monitor wiring system suitably housed in weatherproof cabinet
This incorporates incoming power Solar Panel the direct current power cable a DC isolator and an invertor all of this state of art
From the invertor a low voltage (LV) cable with isolator feed into an LV Uninterruptable Power Supply Unit ...... now called a Battery Pack. This will include power input output and power storage control & monitor features
From the UPS a low voltage power output cable serves a power distribution board and all of this is state of art From the distribution board a series of series of innovative radial L V circuits feed the main power & control and monitor circuitry components these being outlined as follows
The LVpower serves a novel control unit, an extendable support column motorised lift pump an optional motorised dump valve, an automatic/ manual support descent timer and a wind turbine stop start facility
Additionally an optional electromagnetic counter torque device and an optional electromagnetic tie rod locking device being part the extendable support
Optionally power is available to operate a combined daylight and dusk daylight sensor
A state of art twin socket outlet from the distribution board affords local power for LV power & lighting
Furthermore the above specially designed control unit interfaces with the L V power circuit and components already outlined
And specifically enable the automatic operation control and monitor of these components . 75 The monitoring ensures identification of operation, maintenance and malfunction issues
The control circuit is dedicated to this wind turbine extendable support system and forms part of the novelty . The control & monitor wiring serves the time switch the day light sensor the Electro Meeh, counter torque and locking devices, dump valve height sensor turbine off on switch and lift motor pump controller
