The present invention relates to a hydraulic power generation device for generating electricity from flowing water, that is, flowing water. More specifically, the generator of the present invention is employed to obtain energy from low head water soureces such as algae (currents) and free flowing rivers without the need for dams or artificial lakes (water reservoirs).

A hydraulic generator generates electricity by driving a turbine using kinetic energy in moving water. Conventionally, hydraulic power plants have four main elements: (1) a dam that stores a vast body of water with a tremendous amount of potential energy; (2) a hydraulic tube in which the potential energy of the stored water (low water) is converted into kinetic energy when the water flows toward the turbine; (3) a turbine that obtains kinetic energy and converts it into mechanical energy; And (4) generators that convert mechanical energy into electrical energy. Therefore, in the conventional hydraulic power generation, the latent kinetic energy or water head determines the economical efficiency of electricity generation in the hydraulic power generator.

In free flow of fluid, the kinetic energy (speed of flow) determines the economics of generating electricity. The kinetic energy of currents and free-flowing rivers cannot be depleted without cost. However, the cost of generating electricity from this flow is now ridiculously expensive. For this reason, first of all, the kinetic energy in this flow is spread over a vastly wide water, but the existing hydraulic turbine used in the conventional hydraulic power generator captures the kinetic energy of the vastly spread water as described above. Because you can't. In other words, a turbine specifically designed for free flow is technically possible, but economically inherently impossible to achieve. For example, turbines that have been designed for free flow can generally be seen that the electric generator is located under water, resulting in significant inconvenience and high costs in installation, operation and maintenance.

Methods are known in the art for obtaining energy from free-flowing water or a "low-head" energy source. Many of these methods, however, are designed to derive energy from the fluctuating water movements coming from waves rather than displacements of algae (tide and ebb). For example, Noren 's U.S. Patent Nos. 4,773,221 and 4,277,690 both present floating devices for generating electricity, where the passing waves move the tubes vertically by moving the tubes vertically. The said water is comprised so that a turbine may rotate. In addition, the float patents of '690 and' 221 include movable pistons disposed within the tube to move relative to the tube in response to water fluctuations. The moving piston drives an energy converter (eg a turbine) within the fluid to convert the piston motion into useful energy.

U.S. Patent No. 5,770,893 of yulton (Youlton) are present in suspension apparatus including a straight pipe assembly length differences. The tube assembly of the '893 patent is relatively high in water to fluctuating floats and substantially affects the air columns in each tube. Turbines are provided to power electric power from fluctuations (waves) in the air column caused by varying water levels in the tube. Wood (Wood) of the U.S. Patent Application No. 2005/0167988 by electric arc will compress the air in the standpipe and, in turn, feed the compressed air to compressed air energy to flow into a turbine into mechanical energy and electrical energy into a substantially A device for generating the same is disclosed. However, these devices, which use sea water to generate electricity, are not economically efficient.

U.S. Patent Application No. 2003/0059292 of Baker (Baker) suggests an energy conversion device that can replace the energy available to the bird energy. The device of the '292 patent is submerged in water and includes at least one turbine, at least one outlet, and at least one inlet, wherein the inlet is a hydraulic tube that accelerates water towards the turbine.

Hassard et al. , US Pat. No. 6,568,181, discloses a device for obtaining power from fluid flow, where a submerged concrete structure channel accelerates water and the water is delivered to the fluid drive engine by a tube. .

Several ways to convert algae energy into usable energy are described by the TISEC project at the Electric Power Research Institute. The project is described in detail at http://epri.com/oceanenergy/streamenergy.html, the entirety of which is included in the cited references cited herein.

The low head hydraulic power generator described above can generate electricity without dams, but there are significant obstacles to the commercial viability of these devices. For example, it can be seen that the devices described in the prior art typically require many parts to be built and maintained under water, which is too expensive to form the device, and the devices of the prior art generally Compared to the high cost of the construction, there is a problem in that it does not generate enough energy to meet it.

On the other hand, the low head hydraulic power generator of the present invention is configured to collect energy from currents or streams with minimal equipment floating on the surface while submerged. The hydraulic power generation apparatus includes a floating platform in which at least one turbine is coupled, and the water is accelerated by contact with the turbine at least partially submerged by a transfer pipe. Compared with the device described in the prior art, the present invention provides: (1) All the elements of the device can be built on water; (2) turbine repair and maintenance is minimized due to the installation of the device on water; (3) the position of the inlet can be easily adjusted as needed to maximize efficiency; And (4) the use of commercially produced and sold turbines.

According to one aspect of the present invention, there is provided a floating power generator for obtaining energy from a flow of water in a body of water, the generator comprising: (a) a floating platform comprising a deck adapted to float in water; (b) at least one hydraulic turbine mounted on the floating platform; And (c) a transfer pipe having an inlet submerged in water mounted on the floating platform and an outlet injection unit disposed on the water surface. In a preferred embodiment, the delivery conduit is mounted on a floating platform, is adapted to receive a portion of the flow below the surface of the water at the inlet, and conveys the flow within the conduit. The conveyed flow exits the surface of the water from the outlet jet of the pipe and, for example, strikes an impact hydraulic turbine. After this, the weakened jet is returned to the water. The embodiments described above can be employed to accommodate cross-flow turbines or reaction turbines consistent with the claimed subject matter.

The power generator of the present invention can produce energy economically and conveniently from renewable resources.

Further features of the present invention will become apparent from the following detailed description.

The invention is described in detail below with reference to many embodiments for purposes of illustration and illustration only. Modifications to specific embodiments within the spirit and scope of the invention as set forth in the claims will be apparent to those skilled in the art.

The hydraulic power generation apparatus of the present invention includes a floating platform on which a hydraulic turbine is mounted, and at least one transfer pipe for transferring water and driving a turbine. 1 illustrates the general operation of the present invention. Here, the conveying pipe 10 has an inlet 15 facing the direction of the incoming flow, and an outlet 18 extending from the water surface to the impact turbine 30. The turbine is attached below the platform 20 and the bottom of the platform has an open space so that the turbine 30 is suspended in the air above the water surface. Water enters the inlet 15 of the tube 10; Flowing tube (10); Water jet exits the outlet 18 or nozzle of the tube 10. The tube 10 of FIG. 1 is conical. In the form shown in FIG. 1, the generator 40 and the hydraulic device 50 are placed on top of the turbine 30. Also shown are two points of anchor moored 70 connected to anchor 75, wherein the cable, two anchors, and the anchoring ring are configured such that the cable connects the two anchors and the platform through the anchoring ring. The anchoring ring is preferably an O-ring.

The feed tubes used in the present invention are elongated, stream-lined conduits. The present invention includes a transfer pipe for performing a mixed role of the dam and the hydraulic pipe of the conventional hydraulic power generator. That is, the delivery pipe not only guides water to the turbine, but also changes the flow rate. The inlet of the pipe has a larger cross section than the outlet cross-section, which changes the water at the speed V ₁ at the inlet to the speed V ₂ of the exit jet. The transfer tube can also be operated to increase the pressure at the tube inlet, resulting in better performance. In another embodiment, the tubes may not be tapered, ie may have a generally uniform cross section over the entire length.

과 비교하여 크고, 유사하게 높이 "h"는 출구의 길이 크기

와 비교하여 크다고 가정한다. 물은 비압축성이고 비점성이라고 가정한다. 관을 통해 이동하는 유체는 흐름관(streamtube)을 구성한다. 흐름관의 먼 상류의 면적은 A₀(관의 입구면적 A₁과 같을 필요는 없음)이고, 먼 상류의 속도는 V₀이다. 예를 들어, 관이 물속에서 안정상태로 속력 U로 견인되었다면, V₀ = U이다. Note that the speed V ₂ at the outlet can be less than the water flow rate V ₀ . For example, consider a curved tube curved in the form of "S" having an inlet area A ₁ and an outlet area A ₂ . The centerline of the tube at the inlet is at the depth "d" below the water surface and the centerline of the tube at the outlet is at the height "h" above the water surface. In this example, the depth "d" is the length size of the inlet

Large, similarly the height "h" is the length of the outlet

Assume that it is large in comparison with. It is assumed that water is incompressible and inviscid. The fluid moving through the tubes constitutes a streamtube. The area upstream of the flow tube is A ₀ (not necessarily the same as the inlet area A ₁ of the tube), and the velocity of the far upstream is V ₀ . For example, if the tube is towed at speed U in a steady state in water, then V ₀ = U.

Consider a streamline starting at the far upstream of the inlet and exiting A ₂ . Bernoulli's equation is:

Where z is the vertical position. Upstream with high static pressure is hydrostatic.

Where P _a is the atmospheric pressure (assuming constant) in air. P ₂ = P _a at the outlet because the fluid is incompressible. Substituting the Bernoulli equation:

Now, z ₂ -z ₀ = d + h, thus,

Thus, the outlet velocity, V ₂ , will be less than the flow velocity V ₀ given by the above assumption.

Furthermore, given the mass conservation law,

And, therefore,

If the flow of water is steady, then the volume of water flowing at the inlet and outlet of the tube should be the same. That is, A ₁ × V ₁ = A ₂ × V ₂ , where A is the area, V is the speed of water, 1 is the inlet, and 2 is the outlet. In the conveying pipe, the outlet area A ₂ is smaller than the inlet area A ₁ so that the speed of water must be greater at the outlet than the inlet. The present invention allows the use of conventional hydraulic turbines commercially produced and sold due to the increased kinetic energy of the water flowing in a narrow flow.

The energy provided by water can be estimated as:

Potential energy, PE = mgH,

Where m is the mass of water, g is the acceleration of gravity, 9.8 m / s ² , and H is the height of the water surface or head.

Kinetic energy, KE = 1 / 2mV ² ,

Where m is the mass of water and V is the velocity of water.

In the conventional hydraulic power generator, the potential energy of the water stored behind the dam is converted into kinetic energy. Solving for V, we can get the velocity of water in a hydraulic tube with head H when PE is equal to KE: V = (2gh) ^(1/2) Alternatively, solving for H for a given V value, When PE is equal to KE, an equivalent head head can be obtained corresponding to the given water velocity: H = 1 / (2g) * V ²

In a venturi tube that accelerates water through a tapered channel, the total energy of the water remains the same along the tube. In other words, ignoring the energy lost by friction on the pipe, the sum of potential energy PE, kinetic energy KE and pressure P of water remains the same: PE (a) + KE (a) + P (a) = PE ( b) + KE (b) + P (b), where (a) is the inlet of the tube and (b) is the outlet.

If the vertical distance between the inlet and outlet is zero, then "PE (a) -PE (b)" will also be zero, and the increase in flow rate, expressed as "KE (b) -KE (a)", is the pressure according to the Bernoulli equation. Decreases due to "P (b) -P (a)".

Water will decrease in speed as it moves vertically through a delivery tube such as the one illustrated in FIG. 1. The increase in flow rate, expressed as "KE (b) -KE (a)", is the decrease in pressure "P (b) -P (a)" minus the change in potential energy expressed as the vertical distance traveled by water. . If the vertical distance between the inlet and the outlet is small, the change in potential energy "PE (a) -PE (b)" will also be small.

The kinetic energy of water can also be written as

P (w) = 1/2 * d * A * V ³

Where “P (w)” is the kinetic energy of water per unit time (kW), “d” is the density of water (kg / m ³ ), “A” is the vertical area (m ² ), and “V” is the velocity of water (m / s).

Therefore, if the outlet area of the conveying pipe is 50% of the inlet area, the speed of the water at the outlet is twice as large as the speed at the inlet, ignoring the frictional force. The net effect on the kinetic energy of the water in the transfer pipe (eg, A decreases between V and inlet area) is that the kinetic energy at the outlet is four times greater than the kinetic energy at the inlet.

It is contemplated that more than one transfer line may be arranged to drive the turbine in the original power generator. For example, a transfer tube assembly can be arranged to drive one impact turbine. In addition, multiple tubes can be used on the floating platform to drive one or more turbines. For algae, it may be advantageous to apply at least two transfer tubes offset substantially 180 ° relative to each other so that the tubes utilize the energy of the water from both the tidal ebb and tide.

For example, FIG. 2 shows a schematic view from above of four transport tubes 10, two of which are aligned with respect to each direction of tidal flow and positioned so as to hit a single impact turbine 30 at the center. This illustrates that with the help of the back-to-back transfer tubes, one impact thrust turbine can be a bidirectional turbine without any other modifications.

The shape and position of the feed tube depends on the type of turbine used. Tubes suitable for impact turbines have a conical shape such that the narrow outlet end is located above the water, while the large inlet end is submerged; The tube may be curved or have an S-shape longitudinal axis. Preferably, the inner cross section of the tube is gradually reduced along the flow direction over at least a portion of the tube length; It may be gradually reduced to 95% or more over 2% of the tube length, preferably over at least 10% of the length. This design guides the water flowing through the tubes on the surrounding water surface, allowing turbines, pumps, motors, and generators to be placed on the water for easy maintenance and repair. Also, fewer critical elements submerged mean that the platform can be moved more easily on demand. The specific size, shape, ratio, and position of the tube is not particularly limited and may be modified to improve the power generator's efficiency depending on the location of the power generator, the type of turbine used, tidal flow, and other factors. Can be.

The power generator can use a commercially produced hydraulic turbine. Impact turbines such as Pelton and Turgo turbines are attached to the air; These turbines gain kinetic energy by the injection of water that hits the runner. Cross-flow turbines that rotate around the horizontal axis and generally hang in the air can also be used in the power generator of the present invention.

Recoil turbines such as Francisbine, Kaplan Turbine, and Tyson Turbine are completely submerged in water to block the cavity; The turbine gains kinetic energy in the water as it flows past the turbine blades. Conventional hydraulic power generators with relatively low heads use recoil turbines, while hydraulic generators with relatively high heads use shock turbines. Since high heads have a large amount of latent kinetic energy, hydraulic generators using impact turbines will have low cost of electricity unless there is a change in other circumstances.

When used to utilize energy from an algae flow, the present invention is directed to directionally directing the impact turbine without other modifications to the turbine by positioning the tubes back to back so that water moves to the turbine as the algae enters and flows back. I can make it. In such applications it is preferred to use impact turbines or bidirectional cross-flow turbines. For example, the Pelton turbine or the turgo turbine can be bidirectional with the aid of a transfer tube arranged back to back. 3a and 3b show side cross-sectional views of two cross-flow turbines. Cross-flow turbines (also known as micelles or osberger turbines) have similar aberrations and use the concept of both thrust and reaction turbines. 3A shows a blade 100 in a typical, one-way cross-flow turbine. 3B illustrates a simple modification (change) of the blade 105 in which a cross-flow turbine can be bidirectional.

The amount of energy available from algae with a hydraulic turbine is less than the kinetic energy in water as specified by the above equations. According to the Bet's law, the theoretical maximum that any turbine can achieve is 59.3% of the kinetic energy in the water (ie 16/27). Due to the inefficiency of turbines, gearings and generators, the maximum yield is further reduced. The amount of kinetic energy in seawater algae varies in (1) two tides and two ebbs during one lunar day, and (2) two contrasts and two small tides during a single lunar month. It also depends on the constant change in the flow rate of the water with respect to the cycle.

In addition, the hydraulic generator of the present invention includes a turbine, a generator, a pipe and a floating platform on which the hydraulic device is mounted. When the impact turbine is mounted on the platform, the turbine is suspended in the air above the water. Two different methods of mounting the impact turbine on a floating platform are useful. First, the platform has an open draw so that the impact turbine can be mounted to the platform while suspended in the air between the bottom of the platform and the bottom of the water surface. Secondly, the platform can have large air-tanks beneath the floor, and the impact turbine is mounted on the platform between the air-tanks while suspended in the air between the platform floor and below the water surface. The turbine and the feed tube are positioned on the platform such that water jets from the outlet of the feed tube hit the turbine above the water surface and continue to retreat under the flow. This can be clearly seen, for example, in FIG.

The platform may be floated by the pressure of the displaced water near the platform's hull, or by the buoyant force given by an air-tank that can be attached under the platform. The advantage of using an air-tank is that the bottom of the platform is above the water surface so that a simple cupper, not a mechanical pump, can drain the water from the platform.

In the various aspects of the present invention, the stray power generation device includes a group of stabilizing ducts attached to the bottom of the platform. Each duct has a uniform size along its length and is substantially parallel to the conveying tubes. The delivery tube may be secured between the parallel ducts such that the parallel duct and the inlets of the delivery tube all point in the same direction and all the inlets are symmetrical across the flow. The function of the parallel duct is similar to that of the wind vane. Parallel ducts using the velocity of water flowing through the ducts will stabilize the entire stator structure and the conveying pipes, especially against yawing, pitching and rolling movements caused by waves and winds. . Parallel ducts will also be provided as structural supports for the delivery pipes. When used with conical tubes, it is understood that the tubes can be curved, especially near the outlet injection, but the stabilizing duct should be aligned substantially parallel to the tubes.

The invention also includes a suspension mooring structure having a rope and an anchor, which forms an automatic yaw structure. As the flow pushes the float generator until the rope is taut, the suspension berth moving with the parallel ducts will automatically align the inlet of the parallel duct and the transfer pipe using the flow of the flow. 4 and 5 show schematic diagrams of the parallel duct 60 used with the transfer tube 10 and the anchoring structure 70. In the figure, each parallel duct 60 is a cylindrical tube; The conveying pipe 10 is fixed between the parallel ducts 60 so that both the parallel ducts and the inlets of the conveying pipe face the same direction; The inlet is symmetrical across the flow. 4 also shows two suspension moores 70 that anchor the structure to anchor 75 with an anchoring claw 78 disposed around the berth. The use of anchoring rings allows for tie-down structures, and anchor points do not necessarily have to be orthogonal to the water flow. That is, the length of the cable on both sides of the anchoring ring can be automatically adjusted to align the floating generator with water flow. FIG. 5 illustrates a bidirectional shape having a tube 10 and a pair of two suspension anchors 70 positioned in opposite directions from each other; This shape can utilize algae flowing in either direction.

The present invention may also optionally include a hydraulic system that couples the turbine with a standard electric generator to generate electricity. The generator can be located near or adjacent to the turbine on the floating platform, or it can be located offshore. Currents flow at varying speeds in terms of lunar day and lunar month. The hydraulic system is capable of an infinite gear ratio so that the generator can be moved at a constant rpm regardless of the rpm of the turbine; The mechanical gear device, in comparison, has a limited capacity for changing speeds of currents.

Specific embodiments of the invention are further described with reference to the additional drawings. Various features of the embodiments can be used with the various shapes described herein. 6 and 7 illustrate one embodiment of the present invention that includes at least two transfer tubes 10 positioned at about 180 ° relative to each other for operation in tidal flows. The conveying pipe 10 is disposed after the parallel duct 60; The impact turbine 30 is suspended in an open space below the platform 20; The platform houses a generator 40 and a hydraulic pump / motor device 50 disposed between the turbine 30 and the generator 40; The entire floating generator is anchored through a pair of two suspension moores 70. FIG. 7 shows a similar shape with multiple air-tanks 80 mounted on a floating platform.

8 illustrates another embodiment in which the delivery pipe 10 is configured to impinge the impact turbine 30. 8 also illustrates various methods of constructing the air-tank 80, the stabilization duct 60, and the delivery conduit 10. In this embodiment, the floating generator is depicted as a generator 40 and a hydraulic pressure 50 on the platform.

When the present invention is equipped with a cross-flow turbine, the shape of the transfer tube may be an extended rectangular duct having a reduced cross section near the turbine, with the two transfer tubes substantially extending to form one passage as shown in FIG. It is connected at the top except for the opening (opening).

10 is a diagram of an embodiment of the present invention including a cross-flow turbine. A rectangular tapered feed tube 12 is located between the parallel ducts 60; The cross-flow turbine 32 is suspended in the air above the surface of the body of water and under the bottom of the platform 20. The platform is also equipped with an air-tank 80. The platform houses a generator 40 and a hydraulic pump / motor device 50 located between the turbine 32 and the generator 40; The entire floating generator is anchored through a suspension moore 70.

FIG. 11 shows a perspective view, a side view, and a top view of a feed tube 14 fitted with a reaction turbine 34 mounted on a horizontal axis. Many reaction turbines, such as helical and modified Tyson turbines, are bidirectional. Using the bidirectional reaction turbine, the back-to-back transfer tube can be fully welded at the outlet to form the enclosed duct as shown in FIG.

12 illustrates the stray power generation apparatus of the present invention with a reaction turbine 34. The rotating element (ie, runner) of the reaction turbine 34 is completely submerged in the water in the transfer pipe 14. Here again, the stray power generator is depicted with a plurality of air-tanks 80, stabilizing ducts 60, and suspension moores 70. The platform houses a hydraulic pump / motor device 50 coupled to the electric generator 40.

Unique power generators: (1) no construction work required to build dams or dams; (2) use commercially produced turbines; (3) when equipped with impact turbines, without placing electrical elements or moving machinery parts under water; (4) modularized to be flexible in both number and size; (5) can be easily moved when placed; (6) The platform is superior to conventional devices in many respects, providing convenient access for maintenance and repair.
