Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an energy recovery device using L;L tl return ΔY airflow.

Research 1: An energy recovery method that uses new energy to extract energy by converting the motion of waves into air flow, such as the J of a generator, and the driving force of the first stage of energy recovery.
One shot was fired.

In other words, the change in water level due to the vertical movement of waves is converted into the movement of air, which sucks and exhausts the air inside the box.The turbines of various shapes placed in the path of this air movement are avoided, and the rotation of this turbine is controlled. The horns were being supplied to the generator.

However, in conventional turbines, the direction of air movement is constant C [
If I pulled it, I couldn't get the rotation for power generation.

Therefore, it is necessary to incorporate a rectifier valve that regulates the flow of reciprocating air in one direction, making the device large and expensive.

Additionally, energy loss occurs due to opening and closing of the valve, resulting in low efficiency.

The present invention has been made to improve the above points, and provides an energy recovery device using reciprocating airflow that has a simple structure and can always extract kinetic energy without being affected by the direction of air movement. I think it's the first thing to do.

That is, in the present invention, in the passage where the air flow changes to AC-b,
A plurality of straight lines 92 are arranged in a direction across the passage, and these straight lines 9 create a forward component of lift force at a composite speed of acceleration and the rotational speed of W, and are formed into a shape. Both ends of this straight wing are fixed to a fixed disk with a drive shaft in the center, and the rotation of the drive shaft is transmitted to the energy recovery machine:
The present invention relates to an energy recovery device in which the return air flow t, 2, and J is made up of t1 and uE.

Next, I will explain some examples of the present invention.

+1 (] General Description The energy recovery device 1 of the present invention is constructed by connecting a turbine 5 consisting of a straight blade 2, a fixed disk 3, and a drive shaft 4 to an energy recovery machine 6 such as a generator, for example.

Each part of the turbine 5 will be explained below.

[Locosha 11th line & issue! The white line ν·+2 is a vane that converts the kinetic energy of the airflow into a mechanical interlock of lift force J'3 and thrust force.

The straight FA blade 2 is formed of a plate body with a streamlined cross-section and a groove 1, a groove 1, and a ridge.

A plurality of straight blades 2 are arranged in a direction that crosses the airflow.
i! Both ends of the blade 2 are placed parallel to the airflow and fixed to one fixed disk 3.

The cross-sectional shapes of the straight wing 2 are, for example, "S-1 elephant wing" (Fig. 4) configured vertically symmetrically with respect to the center line, "low camber wing" (Fig. 5) configured asymmetrically, and " A high camber wing" (Fig. 6) etc. can be adopted.

From among these, the optimal wing thickness, width, and overall length are determined depending on various conditions such as dosage, acceleration, and rotational speed.

[C] Fixed disk The fixed disk 3 has a plurality of straight blades 2 arranged in a cylindrical shape and fixed in a direction that cuts off the airflow by 41+1, and converts the kinetic energy of the straight blades 2 into rotational motion to drive 8? This is a disk for transmitting information to 1lI4.

The fixed disk 3 may be placed not at both ends of the straight FA 1.2 but at several locations along the way because the straight blade 2 receives centrifugal force while rotating.

In addition, it is possible to fix the straight wing 2 with a fixed disk 3 (in addition to the one shown in the figure, a ring-shaped ring q]υ (supported by spokes 1)). (Illustrated at 4) [2] Fixing the drive shaft I
It's fixed on ho.

Driving! Il axis 4 kL fixed
l 1. This is a shaft for connecting the J'L 11 to an energy recovery machine such as an IJ device (IJ device) that ejects the light 9- into the oil and generates heat.

The drive shaft 4 can also be connected to the rotating shaft of the energy recovery gutter 6 without intervening a power increaser.

[i1\(Rotation principle The rotation principle is the same as all four Grius-type windmills.

In other words, the straight wing 2 that generates lift 4 and is rotating with its cross section to the right,
To the composite speed (relative speed) of the wind speed and the speed of straight wing 2,
When the forward force component of the lift force becomes larger than the backward force component, a force of 1 (] is generated, and continuous rotation accompanied by acceleration is obtained.

Next, the energy recovery method will be explained.

[A] Preparation for energy recovery In FIG. 2, 71 is an air chamber of the box 7, and above this air chamber 71, a communication passage 72 is formed to communicate with the air.

The cross-sectional area of this communicating path 72 is actually a ratio of several tenths to several hundreds of the cross-sectional area of the box 7.

In the communication passage 72, air is moved for suction and discharge due to changes in the water level.

A straight blade is arranged in this communication path 72 so as to cross the communication path 72, and an energy recovery machine 6 is connected to one end of the rotating shaft 4.

[Port] When the intake wave falls, the water level falls and the popular air is sucked into the air chamber 71 through the communication path 72.

Arranged within the communication path 72? The turbine 5) has planar blades 2
receives the lift force and the 111 force and starts rotating in one direction around the driving shaft 4.

As a result, the rotation of the turbine 5 is directly transmitted from the drive shaft 4 to the rotating shaft of the energy recovery machine 6, and Nehru 1 recovery is performed.

[C] Exhaust 1 ['i When the wave changes from 1·μ4 to rising, the air in the air chamber 71 is exhausted through the communication path 72 to the atmosphere.

IJI t) Due to the above-mentioned reason, straight wing 2
receives lift and thrust, and the turbine 5 receives Ir1 at the time of intake.
Continue rotating in the l/i direction.

At the moment when the water level of the wave reaches its highest or lowest level, the air does not move, so the turning force to turbine J is reduced! Although it may be thought that the turbine 5 cannot be recovered by inertia, the rotation of the turbine 5 by 3 degrees due to inertia (energy recovery I) is transmitted to the turbine 6 and a continuous energy recovery machine is performed.

Other embodiments (31st rigid) In order to improve the rotation rate of the turbine 5, the communication passage 7 is
In some cases, a stream guide 8 is provided protruding inside 2 to narrow the passage.

In other words, by pushing the stream guide 8, the flow velocity of the air is increased as it passes through the stream guide 8,
Further, they are arranged before and after the turbine 5, respectively, so that the feed thereof is concentrated in the direction of collision with the direction of rotation Ir of the straight blade 2.

As a result, a forward force of lift is always generated in the straight wing 2, and the wing continues to rotate in a direction opposite to the direction of travel of the airflow.

Since the present invention achieves the above-described effects, the following effects can be expected.

Kuita turbines can obtain rotational motion in one direction regardless of whether the airflow direction is forward or reverse.

Therefore, it is possible to effectively utilize the kinetic energy of the air flow.

〉The direction of the wind changes, but the direction of rotation of the b-turbine does not change.

This eliminates the need for a rectifying device such as a conventional rectifying device, making it possible to downsize the entire device, make effective use of energy, and reduce costs.

Because the turbine is a lift type, high-speed rotation can be easily obtained, so it can be directly connected to an energy recovery machine without intervening a speed increasing device.

As a result, the energy recovery system can be simplified.

<2> The turbine has multiple direction I5j! The structure is simple and easy to manufacture since it consists of only the blade, a fixed disk that supports the straight blade, and a drive shaft.
