Description

The wave power generation apparatus using the pendulum vibration

The present invention relates to a vibratory wave power generation apparatus, and more particularly, to absorb the wave energy in the water surface to the center weight and the power line hull to generate vibration energy with a plurality of vibrators and to convert the rotation energy into the idle gear and the sprocket into electricity It relates to an oscillating wave power generating device.

Waves absorb energy from wind, tidal waves, earthquakes, etc. and continue to absorb energy by forming a swell with inertial force or moving (static wave) in standing state. The inertial force disappears, and even a traveling wave emits tremendous energy so that water does not flow near the surface of the water, but only energy travels in waves and hits an object, soaring up to several times the height of the wave.

Because the moving wave, standing wave, or floating object on the surface is shaken by the waves because the object absorbs wave energy, the vibration weight attached to the object also vibrates at regular intervals. Even if the energy supply is interrupted, the inertia force causes the vibration to continue for a while.

When the shaft hanging on the oscillating weight moves to the side, the vertically suspended oscillating weight moves in the direction of movement because of the inertia to maintain the vertical position.The shaft moves in reverse while passing the point where the inertia must be stopped once. Since the vibration weight is combined with the kinetic energy to restore to the vertical state, the vibration width becomes larger, so that the vibration continues as long as the shaft is shaken. Therefore, if the moving direction and speed of the shaft coincide with the centrifugal force of the oscillating weight, the vibration width decreases, and if the shaft moves in the opposite direction, energy is supplied and becomes larger.

The oscillation period is constant depending on the weight of the oscillating weight and the length of the oscillating weight arm, and the centrifugal force acts on the shaft during the circular motion. The greater the kinetic energy of the shaft than the centrifugal force, the greater the oscillation width.

The moving speed of the oscillating weight is accelerated according to the drop height and weight at both highest peaks, and is slowest when it reaches the lowest peak, and then slowed down again to reach a stationary state. The size is changed and accelerated by the height.

Therefore, the moving vibration weight has energy as much as the dropped height, so if the kinetic energy is less than the braking energy when braking at any point, the movement is stopped or the direction of movement is changed in the direction of the braking energy, and if the kinetic energy is large, the braking device (children It keeps moving by pushing the gears, but it transmits from the moment it connects to the brake system until it falls again and goes up only by the remaining energy.

The magnitude of the vibration energy is proportional to the mass of the oscillating weight and the distance (square of?) The oscillating weight falls, and the vibration decreases or stops when no energy is supplied to continuously vibrate.

The present invention is directed to a device for converting the wave energy dispersed in the hull (generator) to convert the electrical energy to the vibration energy source as a vibration energy source.

The vibrator vibrates because the attractive force acts on the vibrating weight, so even if the hull is turned upside down, the vibrating weight always moves perpendicular to the surface of the water, so when the hull is inclined severely, the vibrator stops and the energy decreases or the vibration stops. .

Since a large number of vibration energy is gathered into one rotational energy, a large energy can be obtained, but if the vibration addition is too heavy, the amount of wave energy that can be absorbed by the hull is limited, so that the absorption rate can not be vibrated when the wave is weak. have.

The main shaft is equipped with many bearings or sheet metals, tooth gears, sprockets, etc., so it is necessary to replenish the lubricant from time to time. Since it is difficult to install the lubricating oil in the driving part, it should be able to check the operation with the real-time power generation and the monitoring camera and replenish the lubricating oil periodically during the operation.

Since the long main shaft is equipped with a plurality of driving parts, especially heavy vibrations vibrate unilaterally, the driving parts should be replaced periodically. In particular, circular bearings cannot be replaced unless they are disassembled up to the sprocket, so a partially replaceable sheet metal or semi-circular bearing is required.

Therefore, the wave energy concentrated on the water surface is absorbed by the wave power generator to generate vibration energy and convert it into rotational energy, thereby reducing the energy loss and producing large energy with a uniform rotation speed. The purpose is to extend the service life of the furnace drive part, to develop semicircular bearings that can be easily replaced by the drive part, and to develop a vibrating wave power generator that can be safely anchored and developed.

In order to achieve the above object, the pipe or I beam, or the center beam combining the I beam and the pipe, extends 1.2 to 3 times longer than the hull to sufficiently absorb the wave energy at the bottom of the wave power generation line, and a length of 5 Cylindrical hull frame made of ~ 20m and 3.5 ~ 4m in diameter is firmly combined to finish with steel plate or reinforced synthetic resin (FRP) panel to keep the interior waterproof and install a hatch at each position of drive and generator Make it easy to access.

A plurality of vibration energy converters are attached to the main shaft bounded by the support and the driving unit at the center of the hull, and fixed to the center or both sides of the main shaft to make the rotation speed of the main shaft uniform and vibration generated during the energy conversion process. In order to suppress the wheel balance is accurate inertial rotor 128, characterized in that the vibration wave generator is composed of a generator which is disposed on the inner bottom of the hull to generate power by the power of the main shaft.

Attach the impact blades to the top of the center weight and the bottom of the hull to which the hull is not attached, and attach the buoyancy bars on both sides of the impact wings so that the hull floats 2/3 or more on the water surface. It allows you to stand up and to wave sensitively to weak waves, absorbing the maximum wave energy.

The vibration energy converting device transmits two vibrator vibration energy vibrating on the shaft of the driving unit coupled to the main shaft to one sprocket fixed to the main shaft by an idle gear, and converts the vibration energy into rotation energy. The main shaft is composed of the hull frame and the support driving unit connected to the support such that the main shaft is located at the center of the cylindrical hull frame.

Therefore, a plurality of vibration energy converters, which combine the one support driving unit, the two vibrators, and the one sprocket in a pair on one main shaft, are integrated into one large rotational energy. Since most of the wave energy is absorbed by the central weight, the length of the hull can be shortened by narrowing the gap between the vibrator, the sprocket and the support drive.

The vibrator is a vibration arm of the length that can be rotated 360 degrees by connecting the vibration arm attached to the fan-shaped vibrating weight of 15-25kg easy to handle in the cylindrical hull with a drive pin and the vibration pin of the main shaft, and the vibration It consists of an auxiliary oscillating weight attached to the vibrating arm to adjust the weight of the weight to generate a large vibration energy from the wave energy, and by attaching a circular gar trail to the hull to suppress movement other than the left and right oscillation of the oscillating weight A pair of pulleys are attached to the bottom of the vibrating weight to reduce friction with the guard rail, and a spring is attached to the top of the guard rail so that the vibration added does not rotate more than 300 degrees. The material of the oscillating weight and the auxiliary oscillating weight may be made of concrete if steel plate is safe and easy to manufacture, but can prevent collision.

Since the bearings need to be replaced periodically due to the unilateral wear of the vibrator drive, only the worn bearings can be partially replaced without disassembling all the parts coupled to the main shaft, and the semicircular bearings or the seats that can use semi-fluid lubricants. The application of sheet metal to the drive unit simplifies maintenance and extends operating life.

Lubricant should be supplied periodically to the driving part, but it is difficult to access due to severe rolling of the hull during operation. Therefore, each driving part penetrates into the inner diameter of the pipe-type main shaft and the lubricating oil supply port, and utilizes it as a lubricating oil supply pipe. The lubricating oil supply pipe is connected with the rotary joint and the hose so that the lubricating oil can be replenished at any time without landing on the hull during operation.

When the vibrating wave power line is anchored in a large number of coasts or seas, one side is bound by a variable ring to the water structure so that the wave energy is sufficiently absorbed, and the other side is arranged in a radiation type by connecting the center weights with ropes.

When anchoring the vibrating wave power line to the shore, it is safe to anchor in the sea before the wave starts by arranging in a row or connecting in a trapezoidal shape. In a place where the wavelength is large enough to cause a spray, the vibration energy may be lost by hitting the vibration additional spring whenever the hull is inclined more than 40 degrees.

It is said that it can produce more than 5 million kw of electricity by using wave energy in the coast of Korea. As long as there are waves and winds that can generate vibrational energy not only on the coast, but also in the ocean, the amount of power generation will be infinite more and the desalination plant of remote areas, islands, drilling ships or deep sea water where transmission is impossible where there are waves that can cause waves on the surface of the water. Can be developed effectively in the same facility.

As long as the anchored rope is not broken, it is relatively safe against high waves, can be manufactured according to electric power demand at the factory, and can be transported at sea as well as on land.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

The narrower the hull, the more sensitive it is, and the more sensitive it is, the more energy absorption is improved, so it is more sensitive to the impact of waves and the center of gravity is below 30-40 degrees, so it can be inclined without being tilted more than 30 degrees. As shown in FIG. 4, a cylindrical hull 21 skeleton is attached to a pipe having an open end, an I beam, or a central weight 125 attached to a pipe under the I beam. The length of the central weight 125 extends 2 to 3 times longer than the hull, and attaches the impact wing 120 and the buoyancy ingot 48 thereon to absorb more wave energy.

The main shaft 32 is firmly bound to the frame of the hull 21 by the support 45 so that the main shaft 32 maintains a straight line at the center of the cylindrical hull, and the outer wall is reinforced with plastic so as not to be broken or deformed by the impact of the waves. ) Finished with panels or steel sheets to prevent water from penetrating into the hull 21 at all.

Cylindrical hull 21 is easy to assemble and repair in the inside and suitable for about 3.5 ~ 4m in diameter to generate a large vibration energy, the length is to promote the left and right vibration of the vibrator 127 and to suppress the forward and backward movement 5 It should be around 20m.

When repairing, since the passage is inconvenient inside the hull 21, a circular hatch 129 may be installed or two to four pieces may be installed to facilitate access to a place requiring repair as shown in FIG. 4 (generator 27, bearing 46). Combine the hatches and attach track- or rectangular hatches.

1 and 2 show a vibrator 127 vibrating about the main shaft 32 located in the center of the hull based on the center weight 125, an idle gear 123 and vibration energy transferring vibration energy. FIG. 3 is a detailed view illustrating the positions of the sprocket 124, the guard rail 126, the spring 41, and the like, which are converted into rotational energy, and FIG. Is a longitudinal cross-sectional view of a vibration energy conversion device showing that the support bearing 77 is disposed between the vibrators 127. Therefore, as shown in FIG. 4, a plurality of vibration energy converters are continuously connected along the length of the main shaft 32 and the inertial rotor 128 and the generator 27 power connection device are bound to the center or the edge.

Since the wave energy is mainly absorbed through the central weight 125, the length of the hull 21 may be reduced by narrowing the interval between the vibrator 127, the sprocket 124, and the support driving unit 77.

The weight of the vibration weight 127a connecting the drive unit 77 and the vibration arm 72 of the main shaft with the vibration pin 71 is manufactured within the range of 15 to 25 kg for easy handling, and the vibration energy according to the vibration state. The auxiliary vibration weight 127b is attached to and detached from the vibration weight arm 72 so as to increase and adjust the vibration width.

The vibrating pin 71 facilitates the detachment of the vibrating weight 127a during repair, and protects the main shaft 32 and the bearing 46 by absorbing and blocking unnecessary shocks such as a collision between the vibrating weight and a back and forth motion.

When the oscillating weight 127a swings back, forth, left and right, and collides with the support 45 or other oscillating weight 127a, the risk of damage is increased, the wear and damage of the bearing 46 are promoted, and energy is consumed. Circular guard rail 126 to suppress the shaking other than the left and right vibration of the vibration weight 127a, the pulley 130 attached to the vibration weight 127a to minimize the friction with the guard rail 126, The spring 41 attached to the upper side of the guard rail 126 is suppressed so as not to escape the limit of vibration when the vibration width is large enough to rotate the vibration weight 127a or the hull 21 is tilted, and the spring ( 41) absorb some of the impact when it hits, and accelerate the fall rate of the vibrating weight in response to the impact.

Two idle gears 123 are attached to the driving unit 77 of the vibrator to connect to the sprocket 124 which rotates in a concentric shaft whenever the vibration speed is faster than the rotation speed, thereby transmitting vibration energy. The larger the distance, the longer the distance and time to connect.

The magnitude of the rotational energy increases in proportion to the number of all the vibrators 127 hanging on one main shaft 32 and the weight of the vibrating weight and the vibrating arm 72, so that the hull 21 according to the height of the wave and the demand of electric power. Adjust the length and the number of the vibrator 127 and the weight of the vibrating weight (127a).

When the hull 21 is shaken, the oscillating weight 127a vibrates at a constant cycle, and since the power transmission of all the vibrators 127 caught on the main shaft 32 is repeated in each oscillation cycle, the rotation speed according to the amount of wave energy absorbed by the hull. Is substantially uniform, and the inertial rotor 128 can maintain a constant rotational speed, thereby delivering high-quality rotational energy to the generator. However, as the weight of the vibration weight 127a is too heavy compared to the amount of wave energy absorbed, the vibration width is narrower, so that the rotation speed is slow and the energy absorption rate may be decreased.

Since all the driving parts 78 are bound to one main shaft 32, the lumen of the pipe-type main shaft 32 is used as the lubricating oil supply pipe 79, and the lubricating oil supply port 134 penetrates into the lumen for each driving part to be used for a long time. Fill the lubricating oil as much as possible, or fill the lubricating oil collection (73) attached to the hull 21 outside as shown in Figure 4 so as to continuously supply the lubricating oil. Semi-fluid lubricant is pushed into the piston with a weight by using the lubricating oil collection 73 as a cylinder, and is replenished as often as the height of the piston lowered.

Since the bearing 45 and the sprocket 124 are mounted on one main shaft 32, one for each support 45 and the vibrator 127, the replacement of the circular bearing is more difficult than the first assembly. In particular, all the sprockets 124, as well as the support 45 in order to replace one bearing 46, so use a partially replaceable sheet metal or semi-circular bearing, such as crank shaft.

Accordingly, as shown in FIG. 5, a semicircular bearing 46 which can be partially replaced and a semi-flowable lubricant can be used, and a cylindrical bearing is used.

Since the vibrating wave power generation is generated floating on the surface of the water can be generated anywhere except in shallow water or rocky areas, the coast near the land may be severely inclined due to high wavelength, so it is better to avoid it.

Although the amount of power generation is not greatly influenced by the direction of wave propagation, and there is little flow of water, the variation of anchoring position is small. However, since it can be affected by wind, the anchorage is anchored in line or ladder with anchor and anchor line (99). And, when there is a marine structure as shown in Figure 6, the anchoring around the marine structure (57) in a polygonal, radiation-type anchor line 99 is too tight, so rolling can be suppressed, so the central weight (125) to the anchor line (99) Loosely fasten and connect the wire cable along the anchoring rope to the substation.

When anchoring one or two ships on the shore, one side is on land, the other side is facing the sea and the route is avoided. Install a buoy.

It is possible to produce electricity cheaply in the place where engine generator mobilization is needed for offshore structures such as islands that cannot be transmitted from land, crude oil drilling ships, deep sea water desalination plants, etc., especially if the waves are anchored firmly so that the rope is not broken. I'm relatively safe, even if I'm not hit by a ship.
