Description

Fluid Collector for Fluid Flow and Hydro Generator and Power Pump Using It

The present invention relates to a turbine, and more particularly, it is possible to easily combine a plurality of turbine rotors to convert the dispersed kinetic energy of the fluid, such as liquid or gas into rotational energy and to collect and amplify the rotational force of the converted rotational energy It relates to a turbine and a cylindrical gear coupled to the rotary blade end and the outer gear is formed.

In general, a turbine is a mechanism for converting linear kinetic energy flowing through a blade into rotational energy and utilizing this energy. The blade is fixed to a central axis and utilizes rotational energy through a rotating central axis. Most of them are used individually.

Therefore, the blade must be large in order to use the kinetic energy of the small fluid per unit cross-sectional area due to the slow moving speed of the fluid. However, if the water is shallow and widely distributed, such as rivers or rivers, the flow is slow, and there are many changes in the water level, the size of the blade is limited and the rotational force is limited. Therefore, in order to utilize the flow energy of the fluid flowing in the stream, it is necessary to combine the rotational force of a small unit generated through the existing turbine, it is difficult to combine the existing turbine using the rotational force of the central axis.

In order to compensate for this problem with a conventional turbine, gears should be connected to the central axis of rotation of a small turbine and connected to each other to increase the rotational force by combining several turbines. To this end, as shown in Patent Publication No. 10-2005-0003976, the center of rotation of a turbine is disclosed. Gears should be geared to the shaft and connected to each other by chains. However, as shown in FIG. 1, in the case of a submersible load and a load such as a tensile force acting on a chain, which is a connection means between turbines, a resistance to hinder the flow of the fluid is generated, resulting in low energy coupling efficiency and high cost for maintenance. .

1 is a view showing a case of combining an underwater turbine according to the prior art.

As shown in Figure 1, the conventional turbine is to use a turbine that is to use the rotational energy in the central axis of rotation alone or when a combination of several turbines should be used when the rotational force is insufficient.

To this end, the gears in the central shaft of the conventional turbine are connected to each other by a chain or the like to use a distributed rotational force.

However, the prior art has the following problems.

First, since the rotational energy is collected through the chain and the like, a loss occurs in the combined energy collected by the frictional force by the tensile force of the chain.

Second, the chain, the central axis and the shaft gear interfere with the fluid flow, reducing the torque of the turbines.

Third, since the rotational force must be coupled through the central axis of the turbine, the central axis should be above a certain strength. Therefore, the thickness of the central axis is thickened to reduce the effective area of the blade for converting the linear motion of the fluid to the rotational motion to reduce the energy that can convert the flow energy into rotational energy.

Fourth, due to the complex drive form for combining the rotational force of several turbines it is not easy to properly respond to environmental changes, causing frequent failures, there is a problem that the maintenance cost increases.

In order to solve the above problems, the present invention is a turbine with a gear having a shape of a combination of a cylinder with a gear blade on the outside of the blade blades to produce a blade to rotate in the opposite direction to each other 2 and 2 of FIG. As shown in FIG. 2, the turbines are arranged so that the cylindrical gears can be directly coupled to each other by crossing each other to collect individual turbine rotational energy, and an energy collection device that collects the flow energy of a widely dispersed fluid such as a river or a river. An object of the present invention is to provide a used hydro generator and a non-powered pump.

In order to achieve the above object, in the present invention, the turbine is a turbine for easily combining the outer rotational force of each turbine to increase the rotational force. For this purpose, the blade end of the turbine is fixed to the inner surface of the cylinder in which the gear is formed outside, and the center is It is a turbine in which a blade is coupled to a central axis (fixed) for supporting each turbine as a whole and a bearing thereof. Therefore, the conventional turbine is a turbine in which the central axis is rotated but the central axis is fixed and the outer cylinder geared with the blade rotates with the blade.

In order to combine the small rotational energy of the small turbine by the kinetic energy of the dispersed fluid using the turbine formed as described above, the directions of the blades are formed to be opposite to each other so as to rotate in the opposite directions to the flow of the fluid in the same direction It is an energy collection device that collects (concentrates) distributed rotational energy by arranging and installing a central shaft continuously in all directions so that the rotating cylindrical gears of the turbine are engaged with each other.

The energy collection principle of the energy collection device formed as described above is that the gears of the respective turbines mesh with respect to the fluid flowing at the same flow rate in a predetermined direction in FIG. 2, so that all turbines rotate freely with almost no restraining force, but restrict the rotation to a specific turbine. When the load is connected, the load that drives the load acts on the specific turbine to which the load is connected, and the farther from the turbine, the smaller the load torque is. That is, if all turbines are geared and rotated at the same speed and the specific rotor is constrained by the load, the constrained rotor becomes slower than the peripheral rotor and the peripheral rotor is constrained to rotate slowly. The rotational force is transmitted to the rotating body. Therefore, it becomes an energy collector in which rotational force is concentrated to the confined turbine. FIG. 2 is a view illustrating an energy collector in which a bevel gear is added to a central turbine rotor gear to transfer collected energy to a load, and the turbine is rotated by connecting the turbine left, right, and up and down according to the load and surrounding conditions. It is also possible to combine more turbines designed to rotate in opposite directions to collect more energy.

The energy collecting device as described above can increase the amount of energy collected as the blades of the turbine become larger and more combined. However, according to the situation of use, an appropriate amount of turbines can be manufactured in an appropriate quantity to be used alone or in a very wide and fast flow environment. In the application, the collected energy is very large and the turbine has to be very robust, so the energy collection efficiency can be lowered. Therefore, the energy collection amount is modularized into the energy collector unit manufactured in an appropriate amount, and the modules are mechanically combined with each other. Preference is given to using.

A non-powered pump that can operate without supplying artificial energy such as electricity from the outside by connecting a hydro generator and a pump to generate electricity by operating the rotor of the generator with the rotation energy collected by combining the generator with the energy collector as described above. Use as a power source for At this time, in order to obtain a proper level of rotation speed, the transmission is combined between the energy collection device and the loads such as generators and pumps and used according to the load.

The geared turbine according to the invention provides the following effects.

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

Second, by converting the flow energy of a small fluid per unit cross-sectional area into rotational energy and easily combining it, the flow energy of a shallow and widely distributed fluid such as river or river can be easily collected as the rotational energy and used as a large energy source.

Third, the kinetic energy of water in places such as rivers or streams with slow flow rates and widely distributed can be used as a hydroelectric generator that generates a large rotational force as an energy collector and uses it as a power source of a generator.

Fourth, by operating the pump with the rotational energy collected by the energy collector can be used as a non-powered pump to operate using only the kinetic energy according to the flow of the fluid without energy provided from the outside.
