Definitions

  • the present invention relates to an apparatus for the conversion of hydraulic energy into kinetic energy, for example, for onward conversion into electrical energy by means of a conventional electrical generator driven by a hydraulic turbine.
  • Such renewable energy resources include solar power, tidal power, wind power, hydraulic power and the like, and many means of harnessing such power and using it to generate electricity has been proposed.
  • many of these energy conversion plants require specific weather conditions e.g. solar and wind power, or have local terrain or geographical requirements e.g. coastline or estuary location for tidal power, mountainous terrain for hydraulic power.
  • such energy conversion plants are often considered to damage the local landscape and often cause unacceptable local noise pollution e.g. wind turbines and the like.
  • a first aspect of the present invention provides an apparatus for conversion of hydraulic energy into kinetic energy, the apparatus comprising: a. a tank containing a fluid; b. a pump motor submerged within the fluid, the pump motor pivotable within the tank about a fixed pivot point; c. a buoyant member contained within the pump motor; d. a ballast member contained within the pump motor, the ballast member containing a ballast tank; e. transfer means coupled to the buoyant member to transfer the upward movement of the buoyant member within the pump motor; and f. pressure differential means operable to move the ballast tank upwards within the pump motor, thereby causing rotational movement of the pump motor about the pivot point.
  • the operation of an apparatus in accordance with the present invention is based on three separate functions, two of which obey fluid mechanics while the third obeys the mechanics of motion of an unstable body under water:
  • Function 1 is based on a buoyant member such as a body of air restrained in a vessel or housing underwater, in a state of non-equilibrium;
  • Function 2 is based on a ballast member such as a liquid ballast tank that is allowed to move vertically upwards within the buoyant body under its own differential hydrostatic forces a predetermined distance and is thus able to alter the centre of gravity of the apparatus; and
  • Function 3 is based on a pivoting support supporting the pump motor on a frame and enabling rotation of the pump motor relative to the frame, thus allowing for a half cycle, thereby allowing the repeating of functions 1 and 2.
  • the pump-motor is held at a non-perpendicular angle relative to the base of the tank. This contributes to the instability of the pump motor when the ballast member alters the centre of gravity of the apparatus by moving about the pivot point.
  • the transfer means comprises a cable engagement mechanism.
  • the pressure differential means comprises a pair of opposing air tanks coupled by means of one or more hollow tubes and in fluid communication with a ballast tank located therebetween.
  • the ballast tank is preferably centrally located between the pair of opposing air tanks.
  • a bellows system may be provided to control any leakage of external water into the interior of the pump motor.
  • the water that is inside the machine which is there to fill space within has pressure as controlled by the fixed vertical head distance between the bottom of the higher air tank and the top of the lower air tank i.e. between the two facing surfaces of the air tanks, during the upward movement of the ballast member.
  • movement of the ballast member from below to above the fixed pivot point causes rotation of the pump-motor.
  • Rotation of the pump motor about approximately 150 ° results in the pump motor being reset for a further cycle of upward movement of the buoyant member and ballast member.
  • the apparatus further comprises a constraining means to constrain rotation of the pump motor when the ballast member moves above the fixed pivot point. In this way, the moment at which the pump motor is rotated can be controlled. Thus, rotation of the pump motor the moment the ballast member moves above the pivot point and destabilises the pump motor is prevented.
  • the apparatus may be further provided with a releasable locking means to restraint the movement of the buoyant member during rotation of the pump motor.
  • Such releasable locking means may comprise a suction effect, a fastening means, or any other suitable releasable locking means known to the skilled person.

  • the apparatus of the present invention is operable independent of geographical location. Further, the efficiency of the apparatus is independent of the size, and the output of each apparatus can be matched with the specific energy requirements of the location in which it is sited. Thus an apparatus in accordance with the present invention is highly practical and because it utilises a renewable energy source, it is of significant economic and environmental value. There are no emissions or byproducts from the working apparatus and the apparatus itself can be partially or wholly located underground so as to be visually unobtrusive.

  • Movement of buoyant member 35 is restricted to a certain distance 2x, as shown in figure 2, without breaking the fluid surface, such that the centre of gravity 45 of buoyant member 35 rises from below the machine frame pivot point 30 to above the machine pivot point 30 during the first function of the half cycle of operation of the apparatus.
  • Cable engagement mechanisms 55 are coupled to the buoyant member 35 by means of tie rods 60 (see figure 2) via a cable 65 to a pumping station 70.

  • the stored energy of the buoyant member 35 is transferred by the cable engagement mechanisms 55 attached to the buoyant member 35 to pumping station 70, thereby pumping water to a higher elevation into a reservoir 75.
  • Figure IA clearly shows buoyant member 35 and ballast member 50 at the end of their up -thrust travel and the bellows system 110, 115.
  • the pump motor 20 is then forced to rotate through 150 ° in a first direction due to displacement of the ballast tank 95 from below to above the machine frame pivot point 30.
  • This displacement is achieved by utilising the differential pressures acting on the ballast member 50 resulting in Force where pressure in the direction of P2 is greater than pressure in the direction of Pl (see figure 4).

  • the force created by this differential pressure will lift the ballast tank 95 together with the pistons and the rods 90, that is the ballast member 50 independently of the buoyant member 35 through a distance 'x' (see figure 4) that is sufficient to cause the whole pump motor 20 assembly to be unstable.
  • Releasing the buoyant member 35 from the rubber seating 125 will provide the hydraulic energy for conversion into kinetic energy and in turn releasing the ballast member 50 from rubber seating 120 and subsequent displacement of the ballast member 50 centre of gravity from below to above the machine frame pivot point 30 will initiate rotational movement of the pump motor 20 back through 150 ° (i.e. from the position shown in figure 6 back to the position shown in figure 1).
  • the releasing of the buoyant member 35 and ballast member 50 from their seating at every half cycle is achieved by means of an electrical solenoid valve 25 action. As soon as this is done, the cycle will be repeated from fig 1 to fig 6 to fig 1.

  • the first function is based on a buoyant member 35 restrained within a pump motor 20 under water, in a state of non-equilibrium.
  • the second function is a liquid ballast member 50 that is allowed to slide up under its own differential hydrostatic forces, a determined distance within the buoyant member 35 and is thus able to move the centre of gravity of the pump motor 20 (see Fig 1), and thereby destabilise the whole system.
  • the third function is a fixed pivot point 30 that enables rotation movement of the pump motor 20, thereby allowing the repeating of functions 1 and 2.
  • the pump motor 20 is anchored to the base of tank 15 and is constrained to swing about a fixed pivot point 30 positioned at a distance 'y' below the pump motor's centre of gravity 45. Moreover the pump motor 20 is tilted to an angle of ⁇ i degree to the vertical (see figures 1 & IA).
  • the pump motor 20 If the centre of mass 45 of the pump motor 20 lies above the fixed pivot point 30, and the weight of the pump motor 20 is greater than the buoyancy & frictional forces acting on the pump motor 20, then the pump motor 20 is unstable and will swing in an anticlockwise direction (see figure 5) to a position at an angle of O 2 to the vertical (see figure 6).
  • the apparatus 10 exploits the energy stored in a buoyant member 35 submerged and restrained under water, in a state of non-equilibrium.

Because of the characteristics of water if pressure in the direction of P 5 is greater than the pressure in the direction of P 4 + mg, then buoyant member 35 will rise. The buoyant member 35 will rise inside the machine frame shown in figure 3 until the upper red surface of the buoyant member 35 reaches the upper rubber seal chamber 125 as shown in Fig 9.
