Description

An apparatus for collecting flow energy of a fluid and a hydropower generator and a non-powered pump using the same,

The present invention relates to a turbine, and more particularly, to a turbine capable of easily converting dispersed kinetic energy of a fluid such as a liquid or a gas into rotational energy and collecting and amplifying the rotational energy of the converted rotational energy through a plurality of turbine rotors And a turbine having a cylindrical gear coupled to the outer periphery of the turbine.

Generally, a turbine is a mechanism for converting the linear kinetic energy of a fluid flowing through a blade into rotational energy and utilizing this energy. The blade is fixed to the central axis, and the rotational energy is utilized through the rotating central axis And most of them are used individually.

Therefore, since the moving speed of the fluid is slow, the blades must be large in order to utilize the kinetic energy of the small fluid per unit area. However, water such as a river or a stream is shallow and widely dispersed, and the flow is gentle. In the case of a large change in the water level, the size of the blade is limited, and there is a limitation in increasing the turning force. Therefore, in order to utilize the flow energy of the fluid flowing in the stream, it is necessary to combine a small unit of rotational force generated through a small turbine. It is difficult to combine a conventional turbine using the rotational force of the center shaft.

In order to overcome this problem with conventional turbines, gears should be mounted on the rotating center shaft of a small turbine, and a plurality of turbines should be connected to each other to increase the rotational force. For this purpose, it is necessary to attach gears to the rotational center shaft of the turbine and to connect the gears with chains or the like as in Patent Publication No. 10-2005-0003976. However, as shown in Fig. 1, in the case of underwater turbines used in a load such as tensile force acting on a chain, which is a connecting means between turbines, and in water, a resistance that interrupts the flow of the fluid is generated, Costs are incurred.

FIG. 1 is a view showing a case where an underwater turbine according to a related art is combined.

As shown in FIG. 1, a conventional turbine is required to use a turbine which is supposed to use rotational energy in the center of rotation, or to combine several turbines when the rotational force is insufficient.

To this end, the gears in the conventional center axis of the turbine are connected to each other by chains or the like, and the rotational torque is dispersed and used.

However, the related art has the following problems.

First, since the rotational energy is collected through the chain or the like, a loss occurs in the binding energy collected by the frictional force due to the tensile force of the chain or the like.

Second, the chain and the center and shaft gears interfere with fluid flow, reducing the rotational forces of the turbines.

Third, since the rotational force must be coupled through the center axis of the turbine, the center axis must have a certain strength or more. Therefore, the thickness of the central axis becomes thick, so that the effective area of the blade for converting the linear motion of the fluid into the rotational motion is reduced, thereby reducing the effective energy for converting the flow energy into rotational energy.

Fourth, due to the complicated driving mode for combining the rotational forces of the plurality of turbines, it is not easy to appropriately cope with the environmental change, and frequent failures are caused and maintenance costs are increased.

In order to solve the above problems, the present invention provides a turbine having gears having gears formed by coupling a cylinder having a gear to the outer periphery of the turbine blade, two types of turbines of FIGS. 2 and 3, Each type of turbine is arranged so as to be directly coupled to each other by intersecting each other like [representative figure] so as to collect the rotational energy of each turbine, thereby collecting the flow energy of widely dispersed fluid such as steel or river And a hydraulic power generator and a nonmotor pump using the same.

In order to achieve the object, in the present invention, the turbine is a turbine for easily combining the outer rotational force of each of the turbines to increase the rotational force. To this end, the blade end line of the turbine is fixed to the inner surface of the cylinder, (Fixed) for supporting the entire turbine of the turbine, and a turbine in which the blade is combined with the shaft as a bearing. The conventional turbine thus rotates the central axis, but the present invention is a turbine in which the cylinder with the external gear coupled with the blade fixed with the central axis rotates with the blade.

In order to combine the small rotational energy of the small turbine due to the kinetic energy of the dispersed fluid using the turbine formed as described above, the blades are formed in opposite directions to each other so as to rotate in opposite directions with respect to the flow of fluid in the same direction And the cylindrical gears located on the outer periphery of the rotating body of the turbine are arranged in such a manner that the central axes are disposed continuously in four directions so as to interlock with each other to collect (concentrate) the dispersed rotational energy.

The principle of energy collection of the energy collecting device formed as above is such that, in [representative view], the fluid flowing at the same flow rate in a certain direction is engaged with the gears of the respective turbines so that all turbines rotate freely without any binding force, When a restraining load is connected, a load that suppresses the rotation of the turbine is applied to the specific turbine to which the load is connected, and such a turbine of 2, 3, ..., n coupled to the turbine directly coupled to the load, The smaller the load torque is, the more the load torque acts. That is, when all the turbines are coupled with gears and rotate at the same speed, when the specific rotating body is restrained by the load, the rotating speed of the restrained rotating body becomes slower than that of the surrounding rotating body, So that the rotational force is transmitted to the rotating body. Therefore, it becomes an energy collecting device in which rotational force is concentrated by the constrained turbine. In this embodiment, a bevel gear is added to the center turbine rotation gear so as to transfer the collected energy to the load. In accordance with the load and the surrounding conditions, the turbine includes a turbine connected to left and right, May combine more turbines designed to rotate in the opposite direction to collect more energy.

The energy collecting device as described above has a large amount of energy to be collected as the blades of the turbine are larger and more combined. However, according to the circumstances, it is possible to manufacture the turbines of an appropriate size and use them independently, The energy collection efficiency may be lowered because the collected energy is very large and the turbine must be very rigid. Therefore, the energy collection unit is modularized into the energy collection unit manufactured by a proper amount, and the module is mechanically coupled to each other Is preferably used.

A non-dynamic pump capable of operating without external energy supply such as electricity by connecting a pump to a hydraulic power generator for generating electricity by operating the rotor of the generator with the rotary energy obtained by coupling the generator to the energy collecting apparatus described above As shown in Fig. In order to obtain an appropriate level of rotation speed, it is preferable that a transmission is coupled between the energy collecting device and a load such as a generator and a pump so as to be adjusted according to the load.

The turbine with gear according to the present invention provides the following effects.

First, it provides a turbine capable of increasing the torque (torque) by easily combining the small rotational force of the individual turbine converted from the kinetic energy due to the flow of the gentle fluid distributed over a wide range.

Secondly, the flow energy of a small fluid per unit area can be easily converted into rotational energy, and it can be easily collected as rotational energy to be used as a large energy source.

Third, the kinetic energy of water, such as a river or a stream, which is dispersed slowly and widely, can be used as a hydraulic power generator to generate a large rotational force as an energy source for a generator.

Fourth, the pump can be operated by the rotational energy collected by the energy collecting device, so that the pump can be used as a non-powered pump that operates using only the kinetic energy according to the flow of the fluid without energy provided from the outside.
