Description
CYLINDER DEVICE FOR GENERATING ELECTRICAL ENERGY Technical field
The application relates generally to a cylinder device for generating electrical energy. Background
Water has been utilized for a long time in the generation of electrical energy.
Water is typically utilized in Whitewater locations such as e.g. rapids. The hydroelectric power plant constructed on rapids has its turbine installed within the rapids for being rotated by water flowing rapidly therethrough. Rotation of the turbine is converted by a generator into electricity which can be stored or put directly into service.
A problem with these solutions is that the construction of a hydropower plant generally destroys natural flow in the rapids and blocks fish migration upstream along the rapids. Summary
One objective of the invention is to provide a less nature-harming solution, which enables the generation of electrical energy by utilizing the motion of water.
The one objective of the invention is attained with a cylinder device and system according to the independent claims.
According to one embodiment, the cylinder device for generating electrical energy includes at least one cylinder and floats. Each cylinder contains a mobile mass and a turbine. Each cylinder is adapted to swing on waves supported by the floats in such a way that a swinging motion sets the mobile mass inside the cylinder in reciprocating motion first towards a first end of the cylinder and then towards a second end. The swinging motion of each cylinder is enhanced by the floats. The reciprocating motion induces rotating motion of the turbine in each cylinder. The rotating motion drives an electrical energy- producing generator connected to the device.
According to one embodiment, the cylinder assembly for generating electrical energy includes a cylinder device, an electrical energy-producing generator, a coupling member for connecting the cylinder device to the generator, and a battery unit for storing the generator-produced electrical energy. The cylinder device for generating electrical energy includes at least one cylinder and floats. Each cylinder contains a mobile mass and a turbine. Each cylinder is adapted to swing on waves supported by the floats in such a way that the swinging motion sets the mobile mass inside the cylinder in reciprocating motion first towards a first end of the cylinder and then towards a second end. The swinging motion of each cylinder is enhanced by the floats. The reciprocating motion induces rotating motion of the turbine in each cylinder. The rotating motion drives an electrical energy-producing generator connected to the device.
Other embodiments are presented in the dependent claims. Brief description of the figures
Embodiments of the invention will be described more precisely with reference to the accompanying figures: fig. 1 shows a cylinder device based on the motion of liquid
fig. 2 shows a cylinder device based on the movement of a piston fig. 3 shows a cylinder device based on the movements of a piston and pressure walls
fig. 4 shows the functional components of a cylinder device Detailed description of the figures
Fig. 1 shows a cylinder device 100 for generating electrical energy by utilizing a lake or sea water wave motion A.
In the figure, the device 100 is shown in a cross-section at two extreme positions of a swinging motion K and in a plan view.
The device 100 includes at least one cylinder 102 with a first end 103 and a second end 104. The cylinders 102, which are closed at the ends 103, 104, are elongated with a length P exceeding a diameter D thereof.
The cylinders 102 can be manufactured in plastics, a composite material, a stainless metal or the like material.
The number of cylinders 102 can be at least one, e.g. one, two, four, six, or, as shown in the figure, eight pieces. In addition, the device 100 may include floats 106, the number of which can be e.g. two, three, four or six pieces.
The floats 106 can be mounted to the ends 103, 104 under the cylinders 102 or at some specific distance from the ends 103, 104 towards a midsection of the cylinders 102 and under the cylinders 102, whereby the distance between the floats 106 is less than that between the ends 103, 104.
The device 100 can have a cylinder 102 provided with its own floats 106 and/or more than one cylinder 102 can be supported by common floats 106, e.g. by two floats 106 as shown in the figures.
If, contrary to the figures, the cylinders 102 are mounted in series, then each cylinder 102 has its own floats 106.
In the figure, the common floats 106 are fitted under each cylinder 102 in such a way that the cylinders 102 are resting on top of the floats, and the first and second ends 103, 104 of a cylinder 102 are not supported by the floats 106.
The floats 106, in compliance with the surface of moving water, not supporting the ends 103, 104, have an assignment of enhancing the swinging motion K of the cylinders 102, and especially the ends 103, 104 thereof, in the waves A so as to create a height difference E between the ends 103, 104.
The floats 106 can be filled with air or e.g. with a lighter-than-air gas, thereby enhancing the swinging motion K of the device 100. The device 100 can also be configured without floats 106, whereby at least one cylinder 102 complies with water surface so as to produce the swinging motion K and the height difference E between the ends 103, 104.
By adjusting the length P of the cylinders 102, a height H of the floats 106 or the shape of the floats 106, it is possible to influence the frequency (length) of the swinging motion K of the ends 103, 104.
Each cylinder 102 comprises a mobile mass 108 and a turbine 1 10.
As shown in the figure, the mass 108 is made up of a liquid, which can be e.g. water or some other appropriate liquid.
The mass 108 has a task of moving, by virtue of the cylinder's 102 swinging motion K induced by the waves A, within the cylinder 102 in its lengthwise direction P back and forth in compliance with a movement L: when the end 104 is lifted higher than the end 103 by the wave motion A, the mass 108 moves towards the end 103 at a lower position, and when in turn the end 103 is lifted by the wave motion A and the end 104 falls to a position lower than the end 103, the mass 108 that has reached the end 103 begins to move back towards the end 104.
As shown in the figure, the turbine 1 10 can be installed inside the cylinder 102.
The turbine 1 10 can be a dual-purpose turbine, which reverses its rotating direction R on the basis of the cylinder's 102 position or the mass's 108 motion direction L, the cylinder 102 or the turbine 1 10 being provided with identification elements for identifying the cylinder's 102 position or the mass's 108 motion direction L, and with control elements for reversing the turbine's 1 10 rotating direction R on the basis of information obtained from the identification elements. The mass 108 has an assignment in each cylinder 102 to set the turbine 1 10 in rotation by flowing through the turbine 1 10 as a result of the reciprocating motion L induced by the swinging motion K.
Each cylinder 102 is adapted to swing in the waves A, being supported by the floats 106 in such a way that the swinging motion K sets the mass 108 inside the cylinder 102 in the reciprocating motion L between the ends 103, 104, whereby the mass 108 travels, as described above, towards the end 103 and then towards the second end 104 and vice versa.
The reciprocating flowing motion L of the mass 108 instigates the rotating motion R of the turbine 1 10 in each cylinder 102, and the rotating motion R drives an electrical energy-producing generator 434 connected to the device 100 with coupling elements 432.
It is the device 100 that enables kinetic energy of the mass 108 inside the cylinder 102 driven by the wave motion A to be converted into electricity.
The device 100 may further have a fastening means 1 12 for securing it e.g. to an attachment member 1 13 connected to an anchorage 1 14 fixed to a bottom M.
The anchorage 1 14 has an assignment of holding the device 100 stationary, yet allowing its free swinging on the waves A.
The anchorage 1 14 may comprise a float 1 14 which is fixed to the bottom M by means of a mooring member 1 15, e.g. a rope, line or cable. The device 100 can be anchored at a location preferable in terms of its operation, wherein the occurring waves A (wave motion) would be as abundant and long-lasting as possible.
In addition, the device 100 can be anchored so as to enable its turning as determined by the wind that generates the waves A, such that the electricity generation of the device 100 would be as continuous as possible.
Fig. 2 shows a device 100, which matches the device 100 of the previous figure, makes use of wave motion A and is intended for the generation of electricity, yet as a mobile mass 108, each of its cylinders 102 includes not flowing liquid but a solid or liquid piston 108. The piston 108 is intended to exploit a swinging motion L for pushing itself according to the reciprocating motion L towards a first end 103 or a second end 104, and thereafter in an opposite direction.
The solid piston 108 can be made of a one-piece material as frictionless as possible, a single ball, or a string of calls constituted by several balls, which jointly make up a mobile mass 108.
In addition, each cylinder 102 has its turbine 1 10 located externally thereof.
Moreover, each cylinder 102 contains a fluid 209, which is pushed by the piston 108 ahead of itself in the reciprocating motion L.
The fluid 209 may consist of water, air, or some other appropriate fluid.
In addition, each cylinder 102 has each of its ends 103, 104 provided with an outlet connection 1 18 and an inlet connection 1 19.
The connections 1 18, 1 19 of each end 103, 104 are linked to each other with a coupling channel, which in turn houses a single-action turbine 1 10, which drives a generator 434 and by which the generator 434 is rotated.
In addition, each coupling channel includes a valve that is located between the turbine 1 10 and the inlet connection 1 19. The valve is assigned to allow the fluid 209 that has run through the turbine 1 10 to re-enter into the cylinder 102 by way of the inlet connection 1 19 as the piston 108 begins to move away from the end 103 towards the end 104 from where it has earlier glided to the end 103.
It is due to the swinging motion K that the piston 108 pushes the fluid 209 ahead of itself towards the end 103, whereby the end 103 develops a pressure which discharges into the outlet connection 1 18 and the coupling channel. The fluid 209 ejected by the piston 108 proceeds in the coupling channel into the turbine 1 10, developing therein a pressure with its flowing motion and setting the turbine 1 10 in rotating motion R by means of which electricity is generated in the generator 434.
The valve opens, and the fluid 209 that has passed through the turbine 1 10 re- enters into the cylinder 102 by way of the inlet connection 1 19 at the end 103 while the piston 108 is moving away from the end 103 towards the second end 104. The fluid 209, in the process of filling the end 103, may enhance the movement L of the piston 108 directed away from the end 103 towards the end 104. At the end 104, the piston 108, coming towards it, pushes respectively the fluid 209 out of the cylinder 102 by way of the outlet connection 1 18 into the coupling channel within which it rotates the turbine 1 10 and returns, after the valve has opened, by way of the inlet connection 1 19 back into the cylinder 102. In other respects, the device 100 depicted in the figure may comprise components and an operating principle equivalent to those of the device 100 of the previous figure.
Fig. 2 shows a device 100, which matches the device 100 of the previous figure, makes use of wave motion A and is intended for the generation of electricity, but has each end 103, 104 of each of its cylinders 102 further provided with pressure walls 320. In each cylinder 102, both pressure walls 320 are being pushed ahead of the piston 108 as the latter is moving towards the end 103 or the second end 104.
Each of the pressure walls 320 is adapted to push by means of the piston 108 a fluid 209, which may be present in a space between the pressure wall 320 and the end 103, 104, out of the cylinder 102 and to follow the piston 108 in its movement away from the end 103, 104, with the fluid 209 flowing back into the cylinder 102 after having rotated the turbine 1 10 within the channel between the connections 1 18, 1 19.
Each pressure wall 320 may include a spring 322 for enhanced following of the piston. In other respects, the device 100 depicted in the figure may comprise components and an operating principle equivalent to those of the device 100 of the previous figure.
Fig. 4 shows a cylinder assembly 430 for generating electrical energy, wherein is exploited a device 100 shown in any of the preceding figures and included in the assembly 430.
The assembly 430 includes an electricity-producing generator 434, a coupling member 432 for connecting the device 100 to the generator 434 in such a way that each cylinder 102 enables its turbine 1 10 to participate in rotating the generator 434, and a battery unit 436 for storing the energy produced by the generator 434.
The battery unit 436 may include at least one battery, e.g. one, two, three or four batteries.
In addition, the assembly 430 includes a transfer unit 435 for supplying the battery unit 436 with energy produced by the generator 434.
The generator 434 and the battery unit 436 can be mounted on the device 100 in a manner to make up, jointly with the rest of the device 100, an entity capable of being anchored in the waves A.
Alternatively, the battery unit 436 can be placed on a separate carrier external or the device 100, which can be a raft floating on lake or sea water, a platform moored to the bottom M, or a solid ground, such the generated energy is capable of being conveyed by the transfer unit 435 further to the battery unit 436 for storage.
To the separately positioned battery unit 436 can be connected more than one device 100 such that the energy generated by all such devices is stored in one and the same battery unit 436.
