Description

Generating Apparatus Capable of Free Adjusting

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a power generation device, and more particularly, to a free power generation device configured to be able to generate power while being freely adjusted under optimum conditions by a cylindrical body supporting a screw immersed in water lifted or lowered by buoyancy .

Generally, hydroelectric power uses the potential energy of water. In hydroelectric power generation, a turbine installed in a dam is required to utilize the potential energy of water. When water falls on a turbine, the kinetic energy conservation law changes the potential energy of water to kinetic energy that rotates the turbine. In other words, water is confined upstream of the dam, which opens the gate and drops it down the dam to rotate the turbine. In this process, the kinetic energy of the water is converted into kinetic energy of the turbine, and the dam of the dam is needed to utilize the energy of the water. As the rotor coil inside the turbine rotates along the turbine, electromagnetic induction phenomenon occurs and current is generated. This process converts the kinetic energy of the turbine into electrical energy. On the other hand, small hydro power generation is a method of generating electricity by installing a small turbine in a dam or river beam of a relatively small reservoir.

In general hydroelectric power generation as described above, there is a problem that hydroelectric power generation can not be efficiently performed unless the dam size is large or the flow velocity is high. Especially, when the water level of the dam is low in the dry season, not enough water is needed for power generation, and the water can not be drained to the downstream of the dam due to lack of water capacity.

On the other hand, in the case of Korea, there is abundant hydroelectric energy such as a large amount of water flow due to the tide of the tide in the west coast and a sea water flow between the islands of the south coast and the islands. Therefore, if there is a device that can be used for power generation even at a slow speed, it is possible to utilize environmentally friendly energy. In other words, the economic burden of the installation cost can be solved if it is possible to utilize the natural flow rate at the natural rate rather than the method using the rapid flow rate using the after-fresh water after the fresh water at an expensive economic cost.

Hereinafter, the present invention will be described in more detail with reference to an embodiment shown in the drawings.

1 is a schematic perspective view of a first embodiment of a freely adjustable power generator according to the present invention. 1, the free-

A submerged vertical structure 12;

A cylindrical body 13 provided on the outer circumferential surface of the vertical structure 12 so as to be vertically movable and rotatable;

A buoyancy body (B) fixed to the cylindrical body (13) and providing buoyancy;

Support rods (14a, 14a ', 14b, 14c) extending from the cylindrical body (13);

A screw (S) rotatably supported by the supports (14a, 14a ', 14b, 14c);

A power transmission device for transmitting the rotational force of the screw (S); And

And a generator (G) for generating electric power by the power transmitted through the power transmission device.

The vertical structure 12 is dried in a place where there is a flow of water such as sea or river. The vertical structure 12 extends from the floor structure 11 fixed to the seabed or the bottom to the water surface.

The cylindrical body 13 can be raised and lowered along the vertical structure 12 and can also rotate around the vertical structure 12. [ The cylindrical body 13 may be such that two cylindrical halves are connected to each other by a connecting plate 15. (This can be understood from the connection structure of the cylindrical half portions 13a and 13b shown in Figure 2. That is, the bolt 15a is inserted through the through hole 15b formed in the connection plate 15, The two half cylinders can constitute the cylindrical body 13 by being fixed to the cylindrical portions 13a and 13b.) Although only one connecting plate 15 is shown in FIG. 1, the diameter of the connecting plate 15 It will be understood that the other connecting plate 15 is arranged on the opposite side of the direction so that the half cylinders 13a and 13b are connected to each other.

The bearing assembly 17 is mounted on the outer surface of the vertical structure 12 and includes a cylindrical bearing plate surrounding the vertical structure 12 and a plurality of balls 17a mounted on the bearing plate. The plurality of balls 17a are installed on the cylindrical bearing plate so as to be able to roll in place without any change in position. The ball 17a is exposed only to the outside of the surface of the bearing plate, while a part of the surface of the ball is buried in the bearing plate. When the ball 17a is rotated, the object in contact with the exposed surface of the ball 17a can move without friction. The ball 17a can be retracted in place without being detached or separated from the bearing plate since only a part of the sphere is exposed outside the surface of the bearing plate.

The cylindrical body 13 is arranged to surround the bearing assembly 17 and is supported by the ball 17a so that the cylindrical body 13 can move up and down by the bearing assembly 17. The plurality of balls 17a are disposed between the inner surface of the cylindrical body 13 and the bearing plate of the bearing assembly 17 so that the cylindrical body 13 can move up and down without friction.

A float body (B) is provided at the upper end of the cylindrical body (13). The buoyant body (B) serves to support both the cylindrical body (13) and other structures connected to the cylindrical body (13). The buoyant force of the buoyant body (B) allows the cylindrical body (13) to be maintained at an appropriate depth in water, and the size and shape of the buoyant body can be manufactured in accordance with the size of the structure and the site conditions.

An upper locking step 16a for restricting the upward movement of the cylindrical body 13 and a lower locking step 16b for restricting the lowering are provided on the vertical structure 12 at the upper and lower ends of the bearing assembly 17, . The upper and lower stoppers 16a and 16b may be formed in the form of a ring that surrounds the vertical structure, for example. The upper and lower ends of the cylindrical body 13 may be connected to the upper and lower stoppers 16a and 16b, It can be caught by the latching jaw 16b, so that it is possible to prevent the departure of the power generating body and prevent the power generating body from touching the bottom surface, thereby being able to cope with the power loss.

Supports 14a, 14a ', 14b and 14c extend from the surface of the cylindrical body 13 and the screws S are rotatably supported by the supports 14a, 14a', 14b and 14c. In the example shown in the drawing, the first supports 14a and 14a 'extend straight and opposite to each other from the surface of the cylindrical body 13, and the second supports 14b extend to the first supports 14a and 14a' (That is, extending from the surface of another connecting plate 15 disposed on the opposite side of the connecting plate 15 disposed on the front side in Fig. 1) and extending from the surface of the connecting plate 15 at a right angle 14c extend parallel to the first supports 14a, 14a 'while being supported by the second supports 14b. In the example shown in the drawings, it is understood that the first to third supports may be installed at different heights of the cylindrical body 13, respectively. On the other hand, the fourth support rods 14d may be provided to connect the pair of third support rods 14c arranged up and down.

Rotation shafts of both ends of the screw S are rotatably installed on the first support rods 14a and 14a 'and the third support rods 14c. The screw (S) has a shape rotatable by the flow of water. The rotary shaft of the screw S extends through the first support rods 14a and 14a 'and a bevel gear G is mounted on the rotary shaft of the screw S extending through the first support rods 14a and 14a' .

The power transmission device for transmitting the rotational power of the screw S includes a power transmission horizontal shaft 21 extending in parallel with the first support rods 14a and 14a ' And a vertical axis 22 for power transmission extending through the buoyancy body (B). The power transmission horizontal shaft 21 is rotatably supported by bearings 25 fixed on the first support rods 14a and 14a 'and the power transmission vertical shaft 22 is fixed on the cylindrical body 13 (Not shown).

The bevel gear G provided on the rotary shaft of the screw S meshes with the bevel gear G provided on the power transmission horizontal shaft 21. [ And is engaged with a bevel gear G provided at one end of the power transmission horizontal shaft 21 and a bevel gear G provided at one end of the power transmission vertical shaft 22. [ Therefore, the rotational power of the screw S can be transmitted through the horizontal shaft 21 and the vertical shaft 22.

The power transmission vertical shaft 22 extends through the buoyancy body B and is connected to the generator G to thereby drive the generator G. [ The connection between the vertical axis 22 and the rotor of the generator G can be realized by conventional gear engagement known in the art, and therefore a detailed description thereof will be omitted.

In another example not shown in the drawing, the generator G may be installed inside the buoyancy body B. It should also be appreciated that the power transmission horizontal axis 21 and vertical axis 22 and bearings 25, 26 and bevel gears G may be designed to be enclosed by a sealing structure.

The generator (G) configured as described above can generate power by driving the generator (G) by rotating the screw (S) by the flow of water. That is, when the screw S is rotated by the flow of water, the power transmission horizontal shaft 21 and the vertical shaft 22, which are meshed with the bevel gear G, transmit rotational power to drive the rotor of the generator G, This is possible.

On the other hand, when the depth of water changes or the direction of the flow of water changes, the cylindrical body 13 can be raised or lowered to a position where the rotation of the screw S is optimized. For example, when the depth of water changes, the cylindrical body 13 is lifted and lowered by buoyancy of the buoyant body B. At this time, the lifting height can be limited by the upper and lower jaws 16a and 16b. Also, when the direction of the water flow is changed, the cylindrical body 13 rotates around the vertical structure 12, and the position of the screw S can be changed.

2 is a schematic exploded perspective view of a second embodiment of the freely regulated power generation apparatus according to the present invention. Parts of the components shown in FIG. 2 that are the same as those of FIG. 1 are denoted by the same reference numerals as those of FIG.

Referring to the drawings, the two cylindrical halves 13a and 13b can be connected by a connecting plate 15. Although only one connecting plate 15 is shown in the example shown in the drawing, it is understood that another connecting plate is further provided at the opposed positions. The connecting plate 15 can connect the cylindrical half portions 13a and 13b to each other by using the bolts 15a fixed to the cylindrical half portions 13a and 13b through the through holes 15b.

Instead of the bearing assembly 17 shown in FIG. 1, in the embodiment shown in FIG. 2, an upper bearing assembly 30 and a lower bearing assembly (not shown), which are respectively installed at the top and bottom of the cylindrical body, (Not shown), which surrounds the vertical structure 12 and has a smooth surface, can be lifted and rotated. The upper bearing assembly 30 has a plurality of balls 31 mounted on the inner circumferential surface of the annular member 32, as shown in the figure. A part of the spherical surface of the ball 31 is exposed to the inner circumferential surface of the annular member 32 and the other surface not to be exposed is rotatably embedded in the inside of the annular member 32. [ Therefore, the ball 31 can be ballooned on the inner circumferential surface of the annular member 32 without being separated or separated.

The upper bearing assembly 30 is disposed in an upper bearing seat 42a formed as a step on top of the first and second cylindrical body halves 13a and 13b, The upper bearing assembly 30 is fixed by being fixed to the upper ends of the two cylindrical half portions 13a and 13b. That is, the bolts 32b are inserted through the holes 32a of the upper annular plate 32 and engaged with the screw holes 43 of the first and second cylindrical body halves 13a and 13b, 30 are fixed.

A lower bearing assembly, not shown, is disposed in the lower bearing seat 42b and can be secured using a lower annular plate (not shown) in the same manner as described above.

The balls 31 provided in the upper bearing assembly 30 and the lower bearing assembly (not shown) may be formed on a cylindrical plate surrounding the vertical column 12 shown in FIG. That is, instead of the bearing assembly 17 shown in FIG. 1, a cylindrical plate (not shown) having a smooth surface is arranged to surround the vertical column 12, and the first And second cylindrical half portions 13a and 13b are disposed. At this time, when the cylindrical body made up of the cylindrical body halves 13a and 13b is vertically or rotationally moved, the upper bearing assembly 30 and the lower bearing assembly (not shown) are squeezed from the surface of the cylindrical plate .

In another example, in the case of removing the cylindrical plate (not shown) surrounding the vertical column 12, it is possible that the ball 31 is made to roll on the surface of the vertical column 12, Should be understood. It should also be understood that the latching jaws 16a, 16b shown in Fig. 1 may also be provided in the example shown in Fig.

Supports extend from the first and second cylindrical halves 13a, 13b, which may include a stationary support 41 and an insert support 42. The insertion support 42 is interconnected by being inserted through the hollow portion of the fixed support 41. At this time, the length of the support rod can be adjusted by adjusting the length of the insertion support rod 42 inserted into the hollow portion of the fixed support rod 41. The hole 41a formed in the circumferential surface or the side surface of the fixed support 41 is aligned with the hole 42a formed in the circumferential surface or side surface of the insertion support 42 and the key 43 is inserted into the corresponding hole 41a, The mutual fixation between the fixed support 31 and the insertion support 42 can be achieved.

1, the screw S is rotatably supported by the structure composed of the fixed support 41 and the insertion support 42, and the horizontal shaft 21 and the vertical shaft It is understood that a power transmission device including a power transmission device 22 may be installed. In the example shown in FIG. 2, the rotation of the screw S is optimized by lifting and rotating the cylindrical body by the upper bearing assembly 30 and the lower bearing assembly (not shown), thereby power generation can be efficiently performed.

On the other hand, the structure constituted by the fixed support 41 and the insertion support 42 shown in Fig. 2 can replace the first to fourth supports 14a, 14b, 14c and 14d shown in Fig. 1 Should be understood. That is, by configuring a part or the whole of the support rods as a fixed support and an insertion support, the length of the support rods can be varied and can be increased. This makes it possible to modularize the support to make it easier to install, and to cope with increasing the number of screws (S).
