Description

Hydraulic turbine with the folding wings by the curtain, and a structure of waterpower generation plant}

The present invention relates to a vertical wing folding aberration and aberration power plant structure for opening and closing the aberration wings using a curtain, and more particularly, between the aberration wing attached to the drum with a hinge and the fixing jaw attached to the end of the circular plate Bound with a curtain to load water and fold the wings reaching the drain in a chain with water pressure at the inlet to discharge water between the wings so that the water at the drain does not return to the inlet, so the conversion efficiency is high and it is developed into a double flow type. It relates to a wing folding aberration that can be, and aberration power plant structure that binds the aberration in multiple stages according to the depth.

Even in the case of falling conditions such as tidal power and tidal power, the range is very narrow, and the flow direction and the water level change frequently, even in very low drops, the conversion efficiency is high. A power converter (aberration) that generates power on both sides is required.

Aberrations that can satisfy these conditions can be met by installing watermills vertically (vertically) between the aberration houses to allow the water to pass horizontally, but the water carried between the wings at the inlet and air If the fluid is not replaced, the water returns to the inlet, and the rotational resistance is large, and there is little space for water for each rotation, so the rotation cannot be made or the rotation speed is low and the absorbed energy is very weak.

Therefore, drains must be fully exposed, but they cannot be exposed at all times unless a buoyancy device is used. Therefore, it is necessary to be able to exert a function such as replacing water trapped between wings with air.

To solve this problem, the fluid moves between the water pockets by the water pressure, and the water bag aberration repeatedly drains and expands the water bag every time it is rotated by the water pressure difference, and by folding the wings at the drain port and pushing the water The wing fold aberration is typical.

To fold the wings, they must be hinged to the drum and the circular plate, pressed with a roller to fold completely by hydraulic pressure, and a guide plate that blocks the folded space to prevent water from the inlet from passing in the opposite direction to the rotation of the aberration is out of the aberration in the drain. It must be pushed back.

In particular, when the wing tip is rotated over the aberration so that the wing with water is not flipped over a certain boundary, the pulley must be attached so that the tip of the wing does not wear. It must be close between the fixing jaw and the hinge so as not to be strong enough to withstand the energy absorbed by the hinge, fixing jaw, wings, etc.

In addition, the rotational speed of the roller that rotates the back of the wing in orbit and the pulley that moves the aberration house in orbit is several tens of times of aberration, so the wear rate is very fast and especially underwater unless the driving part is frequently replaced or lubricated. In Esau, no matter how perfect the waterproofing device is, its lifetime is limited.

Therefore, all pulleys and rollers except the hinge are omitted, and the gap between the hinge and the fixed jaw is maximized to divide the rotational energy absorbed by the wing and transmit it safely to the main shaft to reduce the failure rate of the hinge, There is a need for a device that can block this passage.

It is a curtain attached between the wing and the fixed jaw so that the wing can be folded and retracted using water pressure difference.

The larger the wing area, the more energy is absorbed and the force acting is unilateral. (The greater the height, the more the aberration shaft and the blades are made more firmly. You must disperse energy.

Since the aberration is installed vertically, the water flows horizontally and can rotate even when the wings are exposed, the height can be controlled according to the depth, but the higher the production? Since the installation is difficult and the driving part must be installed in the middle, this problem is solved and assembled by installing it in a multi-stage with a certain standard. Lifting operation becomes easy.

The structure of the aberration frame varies depending on whether the aberration house is integrally constructed or separated from the piers, but there is no difference in the conversion efficiency. In the latter case, the clearance between the aberration and the aberration house can be kept narrow.

Therefore, it is necessary to reduce the driving part, which is inevitable for frequent replacement due to frictional wear such as roller and pulley of wing folding aberration, simplify the manufacturing process, and make the function of folding and releasing the wing to discharge water between the wings and return to the inlet. It prevents water from passing through the space where the wings are folded, and it is aimed at developing and using a power converter with high conversion efficiency even in ultra low drop, high power generation and extended life span.

Attached to the wing 43 and the protruding jaw 151 with an oval gasket 86 and a bolt nut 115 coated with rubber. The curtain 66 is comprised.

Cover the inside of the hinge 48 and the hinge shaft with PVC, or insert a PVC pipe between the hinge 48 and the hinge shaft to ensure that the hinge works smoothly, prevents the wear of the hinge and the hinge shaft, and replaces only the worn part. do.

When the wings are folded, the curtain is made to a sufficient width so that the tension of the curtain is not too large, but the shrink bar (156) is inserted at regular intervals so that the gap between the circular plate and the curtain does not open due to the contraction of the upper and lower curtain widths. .

When the aberration is installed in multiple stages according to the depth of water, the air pocket 46 is attached to the upper and lower septum plates, and the retainer 91 is disposed between the upper and lower ends of the bearing 50 and the bearing housing 51 and the air pocket 46. Inserting a gasket 86 between the aberration frame 33 and waterproofing, the upper bearing 50 of the upper aberration can wrap the power connection joint 35 and the bearing housing 51 on the generator shaft 58 Attaching an air pocket 46 having a height therebetween and inserting a retainer 91 between the bearing housing and the air pocket, and the lower driving portion of the lower aberration seals the lower portion of the bearing housing 51 with a waterproof device. Extend the service life as much as possible.

Hereinafter, a vertical wing folding aberration and aberration power plant structure using a curtain according to a preferred embodiment of the present invention with reference to the accompanying drawings.

Both ends of the main shaft 27 are machined with a shaft gear 27a so as to connect power with a top and bottom aberration, or a generator, and bind the bearing 50, and the drum 42 with a plurality of intermediate plates 47 as shown in FIG. ), It is completely sealed to reduce the weight of the aberration in the water by air buoyancy.

The aberration with a rotation radius of 5 m can withstand several tens of tons of water pressure with an arc of 1 to 4 m or more in width and height of one wing 43 according to the diameter of the drum 42. As shown in Fig. 3, four to eight wings having a panel attached to both sides of the grid-shaped wing flesh 43a (wing skeleton) are bound to the drum 42 by a hinge 48, and the outside of the wing tip 43a. The hook is attached to the fixing jaw 29 so that the wings are not bent and bent back, and the hinge shaft or hinge is coated with PVC or a PVC pipe is inserted between the hinge and the hinge shaft to improve lubricity.

1 and 2, the fixing jaw 29 and the protruding jaw 151 is attached to the outside at the edge of the upper and lower circular plate 44, and when the curtain is stretched inward narrowing, between the aberration collection 32 Gaskets 86 and bolt nuts (115) coated with rubber in flat iron, made of a good elastic material by inserting a shrink bar (156) at regular intervals to prevent the folded curtain from protruding out of the wing during the passage. Attached to the protruding jaw 151 and the wings (43).

The curtain prevents the flow of water by blocking the widened space by folding the wings, and presses three to five wings in series by the water pressure of the inlet, and spreads out quickly when the wings reach the inlet. If the width is too narrow, the tensile force is greater than the hydraulic pressure at the narrow drop, so that the wings are not fully folded and the space is widened between the circular plate and the curtain, which may reduce the conversion efficiency.

As the wings spread, the fixing jaw and the protruding jaw may be bent due to the impact when they collide with the fixing jaw, or the engaging portion of the round plate may fall. And combine each band with a post to prevent the curtain from protruding out of the wing.

When binding the aberration in multiple stages, the air pocket 46 is attached to the upper and lower septum 47 of the aberration as shown in FIG. 5 so as to block the inundation of the bearing to the air layer. It encloses the bearing housing, and a rubber ring or urethane retainer 91 is inserted between the bearing housing and the bearing housing and the air pocket 46 to block moisture from climbing up the wall from the outside, and grease is formed between the bearing housing and the aberration shaft. Fill the grease and shut off the flooding with a gasket between the upper and lower water frames.

On the other hand, the upper bearing of the upper aberration is attached to the generator shaft 58 and the air pocket 46 that can completely wrap the power connection joint 35 and the bearing housing 51 as shown in FIG. The retainer 91 is inserted therebetween to waterproof and seal the bottom portion of the lower bearing house of the lower aberration to waterproof.

On both sides of the aberration, a multi-level water gate that can be opened and closed vertically according to the water depth, and as shown in FIG. 3, the bridge 65 and the aberration 32 are fixed to the aberration frame 33 fixing the up-and-down driving part of the wing folding aberration. Assembled into the aberration groove (34) of a power plant structure in multiple stages, when separating and constructing the pier and the aberration house, attach the hexagonal skeleton attached to the aberration house (32) diagonally to the aberration frame, the aberration power from the top generator It can be developed into a dual flow by connecting to.

The greater the clearance between the aberration wing and the aberration collection, the lower the conversion efficiency. Therefore, a brush is attached to the protruding jaw to block the leaking space.

In deep water, install a multi-level gate that opens and closes vertically on both sides of the aberration, which is used to install the aberration and to adjust the amount of power generation and free fall. Increase the safety of the structure.

Since the rotation speed is very slow according to the flow velocity and the radius of rotation of the aberration, even if the low speed generator is selected, the rotation speed is controlled by the accelerator or the automatic transmission.

FIG. 1 is a view showing the discharge of water between the wings 43 by pressing the back of the next wing while the wings 43 are folded by the hydraulic pressure applied to the curtains 66 to fold in a chain. And the water pressure of some of the water exiting the drain through the circular plate 44 is used. 2 is a curtain 66 of the wing 43 reaching the water inlet is folded and the wings are extended to fill the water filled with the tip of the wing spans the fixing jaw (29) rotates to the drain and folded in the shape as shown in Figure 1 Return to the entrance.

Figure 4 shows the rotation process as shown in FIG. 4, when the curtain reaches the water inlet and both water pressures are the same, it contracts and expands the folded wings before water enters the aberration collector 32, and the tip of the wing is fixed between the wings ( 29) rotates with the energy delivered to the main shaft 27, and when it reaches the drain, it is pressed by the end of the chain in front of the folding chain to begin to fold and discharge the water between the wings. Gravity pressing on the blade generates the repulsive energy of the water discharged, the rebound energy is converted into rotational energy at the tip of the blade, so there is almost no energy loss if there is no play between the blade and the circular plate 44.

Water can pass between the wing and the circular plate, curtain and the circular plate to reduce the conversion efficiency, but the conversion efficiency will reach 90 ~ 95% even in the ultra low drop, so it can be used for the monthly wave power generation and the small hydro power generation with the small drop. It is suitable for tidal power and tidal current power converter.

In particular, in the four river basin development projects where multi-level underwater basins are maintained in multiple levels, depending on the inflow from the upstream, they can develop into very low drops while maintaining the management level along with water bag aberrations. It is expected that the same amount of power generation will be obtained, and that the experience of underwater piers installation method that can install pier without water barrier can be applied to tidal power generation.
