Description

Modified water turbine and assistant apparatus of folding up the wings}

The present invention relates to a modified wing folding aberration structure (hereinafter referred to as 'correction wing folding aberration' or 'aberration') in which a portion of the wing folding aberration is replaced with a fixed jaw, and more specifically, the wing is folded at a drain. In the process of increasing the conversion efficiency in the ultra low drop by forcibly discharging the water contained between the wings, the hinge is fixed to the circular plate instead of the pulley that rotates the aberration house in orbit, and the fixing jaw is attached to the drum to fix the energy absorbed by the wing and the hinge. The present invention relates to a crystal wing-fold aberration structure that transmits through the jaw to the main shaft.

Unlike the hydroelectric power generation, the tidal power generation, which is developed by using the water level difference between the open sea and the inland sea (reservoir), varies from time to time in tidal waves within the range of tidal waters. Not only can tides vary between tides up to 1.5m or more, but there are also fluctuations in the rate of rise and fall depending on the scale.

In particular, in the sea area where the maximum tidal interdifference is 7m, it does not exceed 3m, and the reservoir reservoir decreases rapidly as the water level decreases according to the slope of the reservoir. Even if the difference between the low water quantity and the water develops until a little later in the saree, the fall of the free fall is severe, and the water drop with a large effective drop is limited in the amount of power and the time that can be developed.

France's Lance Tidal Power Plant, which started operation in 1967, has only 1 / 8th of the power generation, even 13 meters, while the Sihwa Tidal Power Plant under construction, the Garolim Tidal Power Plant in Incheon, and the Incheon Bay Tidal Power Plant are falling. One of the difficult adjustments is that the reason for giving up power generation is because it uses a propeller, which has a large effective drop and cannot be developed into a bi-flow type, as a power converter.

In Sihwa tidal power plant, 160 million ㎥ of water passes through the power plant and the floodgates per day, but only generates power when it is obtained, so only about 80 million ㎥ (Q) is used for power generation.

To achieve a flow rate of 6 m / sec, the drop must be 4.1 m (H) or more. Therefore, if the overall efficiency (η) of the aberration generator can be maintained at 0.84 to 0.92, the electrical output formula Pe = {(1.024xQxH) ÷ 102 } According to xη, an average of 2,766,000 to 3,029,400 kw of electricity must be produced per day, but 1,512,330 kw is expected because the power generation efficiency will be 0.44.

In tidal power generation, when propellers or turbines are installed horizontally to generate single-flow power generation, widening the drop greatly increases the amount of power generated per unit time, but shortens the time to generate power and decreases the total amount of power generated. If you increase the fall, you will not be able to open a large drop, so the power generation efficiency will drop and the total power will also decrease. In the case of drainage, the reservoir level should be maintained at two-thirds of the car between tidal tides, and during inflow, the reservoir level should be drained to be equal to the low water level in the open sea.

Another disadvantage of the propeller is that the rotational direction is changed according to the direction of the tidal current, resulting in a lower conversion efficiency, and when the accelerator is attached, the flow velocity becomes slower. Since the development of the diet is almost impossible, the one side that has difficulty in controlling free fall is to give up development.

Vertical installations can generate bipolar power generation, but power plants need to be installed much deeper, water gates need to be directed to the propellers. Shallow ground topography can result in soil paralysis paralyzing. .

On the other hand, water bag aberrations and wing folding aberrations operate almost 100% of gravity regardless of the drop because water cannot pass through the wings when the rotation is stopped. Since energy continues to be transmitted until there is little leaking energy, the effective drop is narrow, the conversion efficiency is very high even in the ultra low drop, and there is no need to accelerate while reducing the amount of passing.

In particular, because the aberration is installed vertically, the horizontal flow of the flow rate is maintained as it is, so that even when the drainage port and the inlet port are exposed to the water surface, when the effective drop is reached, the vortex phenomenon can be rotated almost without any change. Since the aberration causes the aberration to rotate in only one direction, the conversion efficiency does not drop at all, and thus it can be developed into a double flow type.

However, water bag aberration or wing folding aberration has many parts with limited service life such as water bag, hinge, pulley, etc., so it is inevitable to periodically repair or replace them. There is.

Therefore, it is aimed to develop a power converter that can reduce the failure rate and use it for a long time and does not reduce conversion efficiency by modifying some parts of the wing-folding aberration which have high conversion efficiency due to its short conversion life due to its short service life. .

In order to achieve the above object, the modified wing folding aberration structure is reinforced with a wing plate 124 on the drum 57 and the circular plate 59 and the middle plate coupled to the main shaft on the main shaft to bind the drive bearings above and below the aberration. In consideration of the rotation radius of the plurality of arc-shaped wings with a pipe-type hinge attached to the drum in parallel with the drum at 1/5 to 1/10 of the width of the blade inwardly, the hinge shaft (34a), the wing 90 When it is unfolded, the fixing jaw 101 is attached to the drum so that the inner end thereof is not caught and is no longer flipped. It is connected to the aberration house of the S-type or X-type, and fixed by the rotation axis of the guide plate 102 to the outer aberration house roller attached to the opposite end by pressing the hydraulic pressure so that three to six wings can be folded in series Folded and block the widened space, and consists of aberration structure and the slats that hold the driver bearing.

A plurality of upright reinforcing hinges 34b are fixed to the drum in the middle of the wings so that the hinges of the wings are not damaged by a strong impact, the hinge shafts are coated with PVC, or between the hinge shafts 34a and the hinges 34. Insert the PVC pipe to make it rotate smoothly.

According to the installation height of the aberration to make a customized wing-type aberration or a multi-step assembly to a certain standard, by combining the upper and lower drive support for fixing the drive unit to make a water wheel frame 116 in the shape of a square. It is assembled in multiple stages by inserting from the seabed to the water surface in the aberration groove 123 installed vertically along the center line of the H-beam, the center column or the aberration structure 38, and connects power to the joint 117 between the aberrations.

Vertically connecting the lifting port 44 from the top of the modified wing folding aberration to the top of the power plant structure, the crane 120 to move along the track from the top of the power plant structure, and the top plate for carrying or repairing the aberration while moving with the crane ( Install 125 to facilitate repair and installation.

When pumping, shut off the power generation with the power connection device between the crystal winged aberration and the generator, and connect with the large gear attached to the circular plate of the crystal winged aberration, and accelerate and convert it into the power of the water pump. Water is transferred to and stored in a pumping reservoir through a pumping channel 122 connected to the top of a power plant structure, and pumping power generation at a time when power generation is stopped to meet power demand or to regulate a drop.

Since it is installed vertically, the conversion efficiency does not drop at all even if the direction of the tide changes, so it is not only suitable for dual-flow power generation. It is high, and the rotational speed and the number of passes are directly proportional, so it is possible to optimize the amount of power generated by adjusting the drop by itself, and also maintain compatibility with water bag aberration, wing folding aberration, spiral wing aberration manufactured to the same standard.

In particular, depending on the depth can be installed in multiple stages from the seabed to the surface, even if the fall is narrowed, even if the rotational speed is slow, a large amount of passing water can secure sufficient rotational energy.

Hereinafter, a modified wing folding aberration structure will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view of a fertilized winged aberration structure 16, and FIG. 2 is an elevation view, which is 1/5 of the width of the wing toward the drum of 6-12 arcuate wings 25 reinforced with wing flesh 124 as shown in FIG. When the hinge 34 attached to the point 1-10 is assembled to the circular plate 59 on both sides of the drum 57 by the hinge shaft 34a, and when the hinge is weak or the wing is too long, there is a risk of breaking the hinge 34. Two to five standing-up reinforcing hinges 34b are additionally attached to the drum 57 as shown in the figure. When the wings 25 are extended, the inner ends are caught so that they cannot be flipped more than 90 degrees. The fixing jaw 101 is attached to the drum 57, and the aberration collector 24 symmetrically surrounds 1/4 of the water inlet and the drain hole along the rotation radius of the wing 25.

When the wing is unable to withstand the impact or absorbed energy, the hinge is more likely to be broken at the hinge part. Therefore, when the hinge 34 and 34b are thicker than the thickness of the wing and the protrusion cannot be avoided, the wing Attach to protrude into the concave surface of.

The hinge 34 is coated with PVC or hinge shaft 34a or sandwiched between the hinge 34 and the hinge shaft 34a so as to rotate smoothly and replace when the wear increases.

As shown in FIG. 5, the rotation axis of the guide plate 102 having the roller 83 attached to the opposite end is attached to the outer side of the aberration collection 24 of the inlet and the drainage port as shown in FIG. 1 or 6, and the aberration wing ( 3 to 6 wings that are pushed into the rotation radius of 25 and press the back of the aberration blade 25 by the pressure of the roller 83 using the hydraulic pressure received by the guide plate 102 to rotate from the drain to the inlet. 25) is folded so that it is serially folded to forcibly drain the water between the wings and blocks the water inlet so that the water of the inlet does not pass into the space where the wings 25 are folded, and is pushed out of the rotation radius of the wing by the flow velocity at the drain. Flies

Wings 25 released from the pressure of the roller 83 is rotated by gravity while being unfolded by hydraulic pressure as shown in FIG. 1 or 6 to the rotation energy absorbed by the blades 25 and the hinge 34 and the fixing jaw 101 Transfer to the circular plate and the drum (57) through.

According to the height of the water passing through the modification of the modified wing folding aberration 16, or to produce a fixed standard as shown in Figure 8 fixed wing folding aberration 16 fixed to the drive frame 116 as shown in Figure 9 and Figure Assembling into the aberration groove 123 of the aberration structure 38 from the seabed to the water surface as shown in 10 in a multi-step, and as shown in Figure 10 to connect the power to the joint 117 between the up and down aberration facilitates lifting for installation and repair Let's do it.

The high-risk underwater work time is minimized by installing and lifting the modified wing-folding aberration 16 using the crane 120 and the top plate moving in orbit over the lifting port 44 vertically leading to the top of the power plant structure 38. It can be reduced, the height of the power plant structure is low and the structure is simple, saving construction cost and management cost.

When surplus power is generated, the power generated by some of the modified wing-folding aberrations 16 is converted into a water pump 121, and stored as potential energy in a reservoir for pumping power generation through the waterway 122 connected to the top of the power plant 38. Pumped generation meets demand when power generation is scarce, demand for electricity rises, or while power generation stops to control downfall.

Crystal wing foldable aberration 16 is a gravity and flow flowing horizontally acts perpendicular to the wing is trapped between the aberration house 24 and the wing 25, when the flow rate and the rotation speed of the wing 25 is the same Since the energy is continuously transmitted by repeating the collision and recoil with the aberration collection 24 by centrifugal force until the rotation radius and the area of the blade 25c is larger, the larger the number of the blades 25c, the larger the energy value.

It is applied to tidal and tidal power generation with narrow free fall, and it can be developed as a double-flow type, and the power generation efficiency can be improved to the best even in small hydro power plants and wave wave power generation facilities.

It can be installed by replacing the water bag aberration, wing folding aberration and spiral wing aberration of the same size.
