Description

Generator of the water propeller in water flow

The present invention relates to an algae generator using a propeller in water, and more particularly, using a propeller as a power converter in a high speed underwater and rotating the algae generator with an accelerator added to the pile while rotating along the direction of the algae The present invention relates to an algae power plant that generates single-flow or dual-flow power using a tidal current generator.

Algae formed by lunar and celestial manpower tend to have low sea level due to the rotation and lunar revolution of the earth, but when the sea level rises and the lower sea deviates from the influence of manpower, Among two tidal tides, the difference between the high tide level and the low tide level is more than 1m each, and the tidal direction changes every time the tidal is replaced, and the narrower the strait and the larger the tidal difference, the faster the flow rate. Fluctuations in flow rate can be large.

This phenomenon can be seen in the narrow straits between land and islands, islands and islands, such as the narrow inlet of the bay and the archipelago of the South Sea. It is rare to maintain a flow rate of 3m / sec or more suitable for algal power generation.

Water has an energy density of about 840 times higher than that of air and can predict the flow rate, so not only tidal currents in the straits, but also effluent from tidal power plants or drainage gates, rivers with a large amount of water passing through, and nuclear power plants or thermal power plants. The flow rate of the cooling water used in the can also be used for power generation.

In tidal power, effluents typically maintain more than 3m / sec, and when the drainage power is at low tide, the flow rate is maintained over a very long distance so that many tidal generators can be zigzag. However, if the tidal power generator is installed too close to the tidal power plant, the flow rate may be slowed down and the water hitting the wings may spread in all directions, resulting in a narrowing of the tidal power generation by increasing the drainage level.

Korea's Ocean Research Team has already completed the investigation of the sea area suitable for tidal and tidal power generation, and has completed the ocean current map. It is estimated that it will be able to produce more than 1 million kwh of electricity from the coast of Korea. It is undergoing test development at Uldolmok in Jindo, Jeollanam-do, and some companies are planning to build an algae power plant that can generate up to 90,000kw / h.

When power is generated from seawater passing through the strait, the water hitting the wings spreads in all directions and collides with the water passing by the water wheel to form a vortex to reduce the flow rate, thus maintaining a constant distance from the generator installed next to it. When it is long stretched, propeller type algae generators can be zigzagd or aquatic power generation facilities can be installed intensively at a distance where the flow velocity is restored to the rear.

The propeller type algae generator is fixed to the pile installed underwater so that the wings are barely exposed and generated and transmitted by submarine cable. Wind power generators can get a lot of energy because the length of one wing is more than 40m and the installation height of the generator is more than 100m above the ground, but the algae generator is installed in a shallow strait, so it can be damaged by typhoons or tsunamis. The length of the can not be produced unconditionally large.

If the propeller shaft and the generator shaft are integrated, the buoyancy caused by the air in the generator box, which must be kept tight, makes it difficult to secure the pile, or it may be lost if the fixing device is loosened during operation. Current-type tidal current generators require connections to prevent the wires from being twisted or broken.

As the bottom of the installation is uneven and usually close to the coast, the depth of water becomes shallower. In the straits with large tidal differences, the water level fluctuates, so the diameter of the propeller blades can be adjusted according to the depth to use the flow rate through the installation as much as possible. To place.

In particular, because the propeller is rotating, the underwater work is very dangerous, so conditions for easier management and safe repair of the fault should be preceded, and safety measures for ships passing through the strait should be taken at the same time.

Therefore, the purpose is to increase the power generation efficiency by selecting the proper power generation method according to the flow rate and the conditions of the installation area, and to develop a propeller type underwater algae generator that can make the best use of the flow rate through the effluent or the strait as the power generation water.

In order to achieve the above object, a propeller having a plurality of wings fixed to the propeller wheel 52 or the propeller base portion 52a by a bolt nut 53 as shown in FIG. By applying the main shaft 27 of the propeller to the gear box 49 in which the 플랜지 -shaped cover is flanged to the support cover upper plate 56 by bearings, the rear side of the propeller 55 is attached by a hinge to stop the power generation. When bent at a right angle to the gearbox, the gearbox is accelerated by a multi-stage accelerator gear (58), which is connected to the main shaft by bearings, and transferred to the generator shaft by the diverter gear (48), and the generator is installed at the top of the pile folder (32a). do.

The accelerator includes a first inward gear 54 fixed to the main shaft, a center gear 58a which rotates in opposition to the first inward gear integrally with the second inward gear on the main shaft, the inward gear and the center. An intermediate gear 58b which transmits power by rotating the ball bearing 35a between the gears 58a, and accelerates to the third, fourth or fifth inward gear, the intermediate gear and the center gear according to the target acceleration magnification. It transfers to the generator by the turning gear (48).

Insert the ball bearing 35a between the upper edge of the generator case 51 and the support cover upper plate 56 and insert the pile folder 32a into the support cover 50 so that the propeller can smoothly return in the direction of the flow of the algae. A propeller type tidal current generator assembled with a drop prevention device composed of a ring 26 fixed to the inside of the support cover so as to be in close contact with the ring 26 attached to the pile folder while maintaining an air pocket. The installation is completed by inserting so that the lower end of the file folder 32a of the file folder 32a overlaps the file 32 and fixed with a bolt or the like.

In a place where the flow rate is slow, as shown in FIG. 7, the accelerator gear 48 and the generator 29 are mounted by fixing the accelerator support 30 at the center of the cylindrical case 24 having the fallopian tubes 31 on both sides thereof. The propeller wheel 52 or the propeller with bolts attached to the blade base portion 52a is attached to the main shaft of the additional gear 28, and the pile 32 placed on the seabed is attached to the bottom of the cylindrical case. Deeply inserted into a support cover 50, a ball bearing 35a and a connection device for transmitting electricity to the submarine cable are installed between the upper end of the pile and the upper plate of the support cover 56, and attached to the pile 32. Installation of the conical propeller type tidal current generator is completed by attaching the release preventing device consisting of the ring 26 to the inside of the support cover so as to rotate in close contact with the ring 26.

The effluent should not interfere with the discharge conditions, and the ocean currents will be zigzag with propeller type algae generators to generate single-flow or double-flow generation without the construction of dams. Can be.

The installation is completed by fixing the standardized product manufactured at the factory and fitting the structure assembled at the site on the pile that is placed, and only 100% of tidal phase is maintained, so there is no environmental change.

Hereinafter, a tidal current generator using a propeller will be described in detail with reference to the accompanying drawings.

1 is a model such as a windmill that is generated while rotating along the direction of the wind by attaching a direction key 55 on the rear side, so that the volume of the gearbox 49 may be reduced, as shown in FIGS. 2, 3, and 4. The rotational energy accelerated by the shaft 27 transfers power to the generator 29 located on the pile 32 as shown in FIG. 5.

If both the accelerator gear and the generator 29 are installed on the main shaft of the propeller in the gear box 49, the gear box must be quite large, so that the space becomes large, so that the flange is large and it is difficult to seal the inside of the gear box in a waterproof state. In order to rotate according to the direction of the tidal current, a device for connecting the generator and the external wire to the connection point between the pile and the gearbox is required, and the generator may be contaminated with gear oil.

Since the pile must be considerably thick in order to be able to support the impact of the propeller tidal current generator, the generator can be manufactured according to the specification of the pile, and the gearbox 49 can also reduce the diameter of the reduction gear 58, especially the inward gear 54.

Since the generator 29 is located at the top of the pile 32, the fixing point of the pile 32 and the pile folder 32a is far from the main shaft 27, so that the fixing state may be unstable. The reinforcement is deeply inserted into the file 32 and fixed.

When the flow rate is very fast at 6m / sec or more, propellers with three to six wings that are narrow depending on the water depth are used, and the slower the flow rate, the lower the conversion efficiency. The propeller wheel 52 or the wing base 52a is attached to the propeller wheel 52 or the base of the blade 52a so as to replace damaged blades, such as propulsion propellers of large ships.

When the flow rate is low and the conversion efficiency is low, as shown in FIG. 7, a cylinder using a main shaft 27 integrated with a propeller shaft and a cone equipped with a rotation speed accelerator inside the cylindrical case 24 having the fallopian tubes 56 on both sides thereof are mounted. The propeller 13 for accelerating the flow rate to the speed control device 28 is bound to the pile 32 so as to generate power while rotating along the direction of the tidal current. Since the generator 29 also rotates according to the direction of the tidal current, a connection device is installed to connect the electricity generated between the support cover 50 and the pile folder 32a to the power transmission cable so that the wires are not twisted or broken.

The direction key 55 is attached to the rear with a hinge and a spring so that the propeller always faces the direction of the tidal current, and the support cover upper plate 56 at the bottom of the gear box 49 so as to rotate the generator shaft 27a smoothly around the central rotation shaft. A ball bearing 35a is mounted between the generator cases 51, and a ring attached to the outside of the file folder 32a (the file folder can also function as a generator case) is mounted on a bolt fixed to the inside of the support cover 50. The assembly is rotated so that the pile folder 32a is fitted to the pile 32 and fixed by bolts or the like.

When installing a large number of propeller tide generators in the strait, install them in a zigzag with regular intervals so as not to affect the flow rate or the direction change with each other. Since the propeller blades 25 are barely exposed to the water, the ship passes through the surrounding area, especially for repair. They should be buoyed and guardrails are provided on the route to warn the divers of danger.
