Abstract

A non-permanently erect wind turbine installation comprises a tower 3 which can be lengthened and shortened, a propeller having blades 1 which can be lengthened, shortened, or folded, a control system 35 which controls the installation, and control sensors 27, 28, 29 linked to the control system. The wind turbine is raised to operate when dark, and is stowed and concealed during the daytime, or during periods of stormy weather, the operation preferably being automatic. The mast 3 is preferably telescopic and pivoted at the base, and may be tilted into position using a pneumatic or hydraulic ram 7. The retracted wind turbine and tower is preferably concealed within a tunnel having a cover 43 (see figure 3). The wind turbine may be part of a multi-tower installation, and may store unused energy in a battery, or by pumping water to penstock reservoir of a hydro power plant for later use.

Description

I
NOCTURNAL HYBRID WIND HYDRO POWER SEYSTEM
Background
This invention relates to retractable wind turbine towers Wind energy development has positive environmental impacts. Wind energy is generally regarded as environmentally friendly, especially when the environmental effects of emissions from large scale conventional electrical generation power plants are considered. There are no by- product wastes or gases. Wind is free and unlimited, and as long as there Is wind, there will be power.
Wind power however has two main drawbacks. Firstly, wind is not always predictable; some days have no wind. The electricity produced by wind turbines is not stored and has to be consumed as it is generated. So when there Is no wind, there is no power.
This results in operational problems to the network it Is connected and inevitably, the consumer suffers.
There have been inventions to address these problems. In 1979, MANLEY patented a hybnd wind-hydra system (US pat. No.4166222).The system addressed the problems associated with the unpredictable nature of wind blows in wind power generation by storing wind energy as water potential energy. The system used power generated by wind turbInes to drive water pumps which pumped water to an elevated ground. The water is then used in hydro power plant.
In 2000, YOUSSEF WASFI (US pat no. 6023105) Invented a system that used wind mills to mechanically drive water pumps to pump water to an elevated ground for use In hydra power plants. His invention was an improvement on MANLEY'S earlier invention.
It eliminated the need to use wind turbines, substantially reducing systems installation costs.
The second drawback of wind energy generation is that, its installation has a perceived negative environmental Impact; that of visibility: the public perception that covering the landscape with wind towers Is unsightly. The Implication here Is that it makes It difficult to obtain planning permission to install wind turbines, limiting full exploitation of wind as a source of energy. By nature, wind turbines need to be sited in well exposed sites.
These are sites likely to have strongest winds. Well exposed sites however are also likely to be the most visible.
Statement of Invention
To overcome this problem the present invention proposes non-permanently erect wind turbine towers and non-rigid folding or retractable propeller blades, giving it the flexibility to be raised and become operational only during non-visibility periods such as night times and foggy days and be lowered and kept out of sight in specially designed coverable tunnels at all other times. The operation of the installation is automatically achieved by use of timers, light and humidity sensors, wind speed measuring devices, compressors and hydraulics.
A primary application of this invention is at hybrid wind-hydro power generating systems in coastal areas, utilising sea water and the windy conditions associated with it and all other inland hydro power Installations. Power generated in wind farms is used in hydro power installations that may be located away from the wind farms.
A second application of this invention Is in single independent unit installations with power storing systems in place. The power generated at night is instantly used and at the same time batteries are recharged. The batteries are used during visibility hours when power generation is off.
A third application of this invention is to meet visibility related power requirements such as domestic lighting, street lights and other road related lighting needs. This is particularly appropriate since wind blows strongest at night.

Description
Figure 2 wind turbine installation includes a vertical member (3) which is attached to foundation (5) constructed from reinfOrced concrete pad build in tunnel (4). The lower end of the vertical member is freely hinged to stud (9) which is impeded into foundation (5). Stud (9) top opposite side of hydraulic arm (7) has extension guard (8) to hold vertical member (3) In place at erect position when raised. Hydraulic arm (7) is freely hinged to the vertical member (3) by connection pin (6). Hydraulic arm (7) is housed In pump (10) which is freely hinged at pin (11) to foundation (13) build in tunnel (4).
Hydraulic pump (10) contaIns hydraulic fluid that is compressed by compressed air from compressor (20) through tube (12). The compressor is powered by batteries (23). Stud (16) build in tunnel (4) acts as a resting support for engine housing compartment (2) at lowered stowed position. Compressor (20) is powered by motor (21) which receives electrical current from batteries (23), via connecting cable (22) and through inverter (19). BatterIes (23) are charged by power from output panel (52) via cable (48) and also by solar panels (25) via cable (24).
Tube (12) is connected to pump (10) and channels compressed air from compressor (20). Switch control box (17) receives signal via cable (18) from control Box (35). Ught sensors (27), fog meter (28) and timer (29) send signals via cables (26), (30), and (31) respectively to interface unit (34) which transmits the signal to control box (35) via cable (18). In the event of strong or gusty winds anemometer (32) will send a signal via cable (33) to control box (35) which will override any signal from interface unit and send shutdown ovenide signal to switch (17) which will trigger the lowering of the installation from vertical and erect position to lowered stowage position.
When engine compartment (2) rests on stud (16), as shown in figure 3, it pushes switch (15) In. Switch (15) at In position will send a signal via cable (76) whIch is wIthin stud (16), to switch (17). This will activate the tunnel cover switch within switch (17) and a signal is send to motor (77) via cable (78) whIch causes the tunnel cover (43) to roll on rail (42) and cover the tunnel (Fig. 4). The reverse is true during vertical member (3) erection process. When hydraulic pump (10) is activated and starts to push vertical member (3) up, engine compartment two starts to lift releasing switch (15) from lock in position. This sends a signal via cable (78), to motor (77) causIng the tunnel cover (43) to roll back to open position. Meanwhile, pump (10) is deactivated causing vertical member (3) and engine compartment (2) to remain still. When cover (43) reaches fully open position, it activates switch (45) (Fig. 4) which sends a signal back to swItch (17) via cable (79). This causes secondary activation of pump (10) which causes the vertical member to raise to fully erect position. Guard (8) is fitted with locking mechanism (36) (Ag. 3) to hold vertical member (3) in place once it is in fully erect position. This minimises undue stress to hydraulic arm (7) and pump (10). The locking mechanism (36) is operated internally by hydraulic arm (7) operation during vertical member (3) lowering and raising process.
Figure 5 (a-c) shows alternative lowenng mechanism in which the vertical member (3) is retracted from fully erect position (Fig. 5a) to resting concealed position (Fig. Sc).
Vertical member (3) Is of vertically retractable type and is fitted with lock-in pin (80) which holds the vertical member (3) in place during fully erect position preventing undue stress to pump (10) hydraulic mechanisms. Pins (80) is automatically operated by hydraulics and electrics to allow retraction and extraction during lowering and raising process.
In large wind turbine Installations, propeller blades (1) can be of retracting or folding type (fig. 5b). During the lowering process, propeller (1) rotation i halted and electrically folded or retracted. On receiving signal from sensors (27), (28) and (29), switch (17) sends a signal to break control system within engine compartment (2). This triggers folding or retracting mechanism of propeller (1). At the same time, pin (80) is released causing retraction process of vertical member (3) to begin.
As the engine compartment (2) reaches its lowest resting and stowage position (Ag.
5c), it pushes switch (44), which activates the process of rolling tunnel cover (43) to dose position covering the tunnel. During the extraction process the mechanism works In reverse. As soon as engine compartment (2) raIses, it releases swItch (15) which causes the tunnel cover (43) to roll back and open the tunnel. At its fully erect position, propeller blade (1) mechanism is activated causing the propeller to open and extend to the normal operating position. The breaking mechanism is released and the propeller is ready to rotate again.
Both lowering and raising and retraction and extraction methanism can be used in combination (Fig 6a-b). Retraction process applicable to figure (5a-c) is used in Initial lowering (flg.6a). The lowering process applicable to figure (2) and (3) is then applied in figure (6b). The combination of these two mechanisms Is applied In instances where vertical member (3) is of larger height. This is to keep the length of tunnel (4) to minimum.
Agure 7(a-c) shows lowering and raising of a multi installation by single control mechanism. The components of the control mechanism and its operation is as described in figure 2 operation. Figure 7(a) is a multi turbine tower Installation system mechanically connected in series by bar (49). Hydraulic raising and lowering system is installed at either end and is operated and controlled by control mechanism as described In figure 2 operation. Figure 7(b) shows the installation being lowered to stowage position. Figure 7(c) shows the installation at a concealed stowage position.
The operation of tunnel cover (43) is as described in figure 2.

Figure 8 shows the application of the invention in a hybrid wind hydro power system.
The system comprises of four independent installations working together. Installation 50, 57, 85 and 65. Installation 50 Is a wind farm installation according to the invention where mechanical energy is converted into electrical energy. The erection and operation of wind turbines installation 50 is as described in figure 2 operation. A method of lowering and raising described in figure 7(a-c) is applicable. Electrical energy generated at installation (50) is converted into mechanical energy at installation (57).At installation (85), potential energy Is converted Into kinetic energy and then to electrical energy.
Installation (65) pumps tail water out of the power house back to the high elevation reservoir (72). Installation 65 comprises of four hydraulic ram pump pumping systems (a-d) and one solar pump Installation (e) connected in series parallel. The number of hydraulic ram pump pumping devices Installed at installation (65) is a function of the volume of tall water out of power house and the available overall head.
When wind blows on propeller blades (1),at installation (50), it causes them to rotate.
The rotation drives generators within engine compartments (2) to generate electricity.
Electricity is conducted from the generator via cable (51) into generator Interface unit (52). Electricity Is drawn from generator interface unit (52) vIa cable (53) to distribution box (54). Current is drawn from distilbution box (54) into water pumps multi installation (57) vIa cables 38 and into motors (55) which drive water pumping devices (56). The water pumping devices (56) sucks water (66) from a lower source (71) via inlet pipe (59) and pumps it out via outlet pipe (58) whIch is fitted with non-return valve (39) into the reverse penstock (64) and Into the high elevation reservoIr (72). The reverse penstock (64) is fitted with non-return valve (40). When reservoir (72) fills with water (66) the stored water becomes potential energy (67). The elevation difference (head) between the lower body source (71) of water (66) and the higher reservoIr (72) will create kinetic energy through penstock (76) which Is converted into electricity by hydro turbine-generator (77) in power house (78). Electricity regulation system Is installed within the power house. The power generated is conducted into the national grid system or to the consumer, through cables (79). The tail water out of turbine (77) is channelled through waste pipe (80) into water pumping installation system (65). Water reservoirs (60) re-stores water as potential energy and water pumping devices (61a-d) are hydraulic ram pumps, devices that uses water to pump water. The water In tank (60) collects and forms potential energy which is released under pressure as kinetic energy through several heads (81) Into hydraulic ram pumps (61) connected in series.
The water Is pumped out of the hydraulic ram pumps through delivery pIpes (88) vIa non-return valve (82) into the reverse penstock (64) and back to the high elevation reservoIr (72).
The waste water out of hydraulic ram pumps (61a) Is channelled via several waste water pipes (63a) and through outlet (62a) into a second reservoir tank (60b). The second tank (60b) creates potential energy out of the waste water from hydraulic ram pumps (61a). The water at the second tank (60b) Is channelled through several heads (81b) into hydraulic ram pumps (61b) and is pumped through delivery pipe (88b) via non-return valve (82b) into the reverse penstock (64) and back to the high elevation reservoir (72). Water tank (60a) is installed at a higher elevation than hydraulic ram pump (61a) similarly water tank (60b) is installed at a higher elevation than hydraulic ram pumps (61b). The lower series installation of hydraulic ram pumps is half the number of the higher series installation, i.e. there are eight hydraulic ram pumps installed In series at pumping system (61a), four at (61b), two at (61c) and one at (61d). This is because approximately 50% of water at each series installation is pumped back through penstock (64) to high elevation reservoir (72) and 50% escapes as waste water which is then collected to be pumped in the next series installation.
The process of series parallel installation (65a-e), is repeated until the volume of waste water out of the lowest elevation hydraulic ram pump Installation (62c) can be sufficiently pumped back to the reverse penstock by one hydraulic ram pump installation (88d).
Hydraulic ram pump (61d) is a single pump installation. Water is channelled to it from water reservoir tank (60d) and Is pumped Into reverse penstock (64) through non-return valve (82d) and via delivery pipe (88d). The waste water out of (62d) is collected into final tank (60e). A solar panel installation (75) powers motor (73) via cable (74) and drives pump (68) which pumps water from tank (60e) Into reverse penstock (64) through delivery pipe (88e) and non return valve (82d). Any excess waste water (70) overflows out of the final tank (60e) and is channelled into the lower elevation reservoir (71) through waste water pipe (69).
The installation is constructed to a ratio of at least 3:1 between the volume of water (66) pumped through the reverse penstock (64) into higher elevation reservoir (72) and the volume going through penstock (76) as kinetic energy into turbine installation (77).
This is to create sufficient reserve potential energy (67) for conversion into kinetic energy at flow head penstock (76). This allows constant generation of electricity at generator-hydro turbine (77) during non-operation of installation (50) at lowered and stowage position. The correct ratio is achieved by increasing pumping power of the pumping devices t installation (57) and (65) and by increasing the water holding capacity at reservoir (72) During visibility hours (Fig.2), light sensor (27) detects light (i.e. at sunrise), and fog sensor (28) (when fog dears) will detect the change in the atmosphere and send a signal to interface unit (34) vIa cables (26) and (30) respectively. Timer (29) can also be set to send the relevant signal at the desired times to interface unit (34). The signal from interface unit (34) is transmitted to override control box (35) via cable (18). The signal from override control box (35) is transmitted to switch (17) via cable (18). The signal will turn swItch (17) so as to release pressure at tube (12) from compressor (20) causing pump (10) to pull back hydraulic arm (7). This causes vertical member (3) to lower into tunnel (4) and the rolling of tunnel cover (43) (Fig. 3) into dosed position.
The reverse process is repeated when it gets dark, fogy or at the set time as per timer (29).
Higher elevation reservoir (72) is fitted with switch floats (86). The switch floats are installed at different level water marks within the reservoir each installation of switch floats is electrically connected to different set of wind turbine installation control mechanism at switch control box (17). When water level at installation (85) is low, all the floats will be down, and thus all the wind turbine generators will be operational. As the water level raises, the lowest switch float raises with it. At fully up position, the switch float triggers the switch it is connected to at switch control box (17) causing the relevant wind turbines at installation (50) to be lowered to stowage position. The process is repeated as the water raises above the higher switch floats until at its highest level all wind turbine installation at installation (50) will be at lowered stowage position.
The reverse process is repeated as the water level at high elevation reservoir (72) drops below switch float installation (86) levels. This will prevent water (66) from overflowing reservoir(72) and allows for optimum utilisation of power generated at installation (50).
During periods of gusty or high speed destructive winds, anemometer (32) will detect gusty high speed winds and sent shut down override signal via cable (33) to control box (35). The shutdown signal will then be transmitted to switch (17) via cable (18). Switch (17) will initiate the lowering process of vertical member (3) and engine compartment (2) into stowage rest position at tunnel (4). When engine compartment (2) rests on stud (16), switch (15) is activated and a signal Is transmitted back to switch box (17) causing current to transmit to motor (77) via cable (78). The operation of motor (77) will cause tunnel cover (43) to roll through raIl (42, figure 4) to shut position (Fig.3).
The stowage of the installation will prevent damage to the equipment when wind speeds are too high.
A signal from wind speed measuring device (anemometer 32) overrides both the signals from light sensor (27), fog meter (28), timer (29) and switch floats (86). Sensors (27) fog meter (28) and timer (29) override any signal from switch float (86).
