As shown in FIG. In addition, as shown in FIG. 4, the bottom portion 42 is formed with an inclined inclined surface 46 inclined toward each inlet side through which seawater flows in the central region in which the bidirectional generator 10 is installed.

This inclined surface 46 is also preferably formed on the shaft support portion 44 on both sides. That is, to increase the power generation efficiency by inducing the seawater flowing between the accessory facilities 100 to the two-way generator (10).

The bidirectional generator 10 is installed at the center of the bottom portion 42 of the support structure 40 to produce electricity by the turbines 30A and 30B which rotate in opposite directions. The hollow housing 12 and In a corresponding position of the inner rotor 14 and the outer rotor 16 and the inner rotor 14 and the outer rotor 16 rotatably provided so as not to interfere with each other inside the housing 12. Coil 19 and permanent magnet 18 provided respectively, and the inner rotor 14 or the outside is connected to the coil 19, the coil 19 is installed to supply the electricity generated from the coil 18 to the external device It is configured to include a slip ring 20 provided in the rotor (16).

In the present embodiment, the coil 19 is provided on the inner rotor 14, the slip ring 20 electrically connected to the coil 19 is provided, and the coil 19 corresponds to the outer rotor 16. It will be described on the basis that the permanent magnet 18 is provided as possible.

Therefore, the electricity generated by the coil 19 and the permanent magnet 18 by the rotation of the inner rotor 14 and the outer rotor 16 is transferred to the shaft portion (area supporting the rotation) of the inner rotor 14. The slip ring 20 provided is supplied to an external device, for example, a place that requires electricity, a power storage device, or the like.

At this time, the rotary region and the housing 12 of the inner rotor 14 and the outer rotor 16 is provided with an airtight means for blocking the inflow of sea water and the rotation is made.

The first turbine 30A and the second turbine 30B for rotating the inner rotor 14 and the outer rotor 16 in opposite directions by the flow of tidal flow are configured as follows.

First, the first turbine 30A is connected to the shaft portion of the inner rotor 14 by a coupling or the like, and the first rotation shaft 32A rotatably supported by the shaft support portion 44 on one side of the housing 12; It consists of first wings 34A installed on the first rotary shaft 32A. That is, one end of the first rotary shaft 32A is coupled to the internal rotor 14, and the other end is coupled to the shaft support 44 on one side. At this time, one end of the first rotary shaft 32A is installed to be rotatably supported by the housing 12, coupled to the internal rotor 14, and a slip ring 20 may be installed at an outer diameter thereof. Each of the first wings 34A is coupled to the first rotation shaft 32A to rotate the first rotation shaft 32A by the flow of the tidal current.

The second turbine 30B is installed at a position symmetrical with the first turbine 30A with respect to the housing 12 to rotate the external rotor 16, and one end of the second turbine 30B is coupled to the external rotor 16.

It consists of the 2nd wings 34B installed in the opposite direction to the 1st wings 34A.

At this time, each blade 34A, 34B is coupled to the first rotary shaft 32A and the second rotary shaft 32B, and the above-described inner rotor 14 and outer rotor 16 may be configured to be coupled to each other. will be.

In the first turbine 30A and the second turbine 30B, the first and second blades 34A and 34B are installed in opposite directions. That is, even if the tidal flow flows in one direction, the first turbine 30A rotates forward, and the second turbine 30B rotates in reverse, and the first and second wings 34A and 34B are installed in opposite directions.

Hereinafter, the operation of the present invention will be described.

A support structure 40 is installed between the accessory facilities 100, and the bidirectional generator 10 includes a first turbine 30A and a second turbine 30B that rotate in opposite directions to the support structure 40. In the installed state, when the algae flows between the accessory facilities 100 by the generation of algae, the sea water is guided to the induction slope 46 to lift the wings 34A, 34B of the first and second turbines 30A, 30B. Rotated.

That is, as shown in FIG. 3, the first blade 34A receives a force of a tidal current so that the first rotational shaft 32A rotates in a clockwise direction, and the second blade 34A is installed in the opposite direction to the first blade 34A. 34B is subjected to a tidal force such that the second rotary shaft 32B rotates counterclockwise.

Therefore, the first rotary shaft 32A and the second rotary shaft 32B rotate in opposite directions.

In this process, as the first rotary shaft 32A and the second rotary shaft 32B rotate in opposite directions, the internal rotor 14 provided with the coil 19 and the external rotor 16 provided with the permanent magnet 18 are installed. ) Rotate in opposite directions.

In this operation, electricity is produced from the coil 19 and supplied to an external device (not shown) through the slip ring 20.

At this time, since the inner rotor 14 and the outer rotor 16 are rotated in the opposite direction to each other, the relative rotational speed (RELATIVE ROTATIONAL SPEED) is doubled. That is, since the inner rotor 14 rotates one direction in the forward direction and the outer rotor 16 rotates one direction in the reverse direction, the relative rotation speed is doubled, thereby increasing the power generation efficiency, for example. For example, a gearbox for increasing the number of revolutions is unnecessary.

In addition, since the first and second turbines 30A and 30B rotate in opposite directions, respectively, by tidal currents flowing in one direction, the directions of the tidal turbines 30A and 30B may also be changed even when the tidal currents, for example, at low tide or high tide. Even if the direction of the bidirectional generator 10 is not changed, the turbines 30A and 30B may rotate in opposite directions due to the flow of the tidal stream, and thus, power generation is performed regardless of the tidal flow direction.

Meanwhile, as shown in FIGS. 1 and 4 to 6 of the accompanying drawings, the bidirectional tidal power generation apparatus using the accessory facility of the bridge according to the present invention may be selectively lifted out of the sea surface by the raising and lowering means 50. have. This is to satisfy various requirements for maintenance, replacement and inspection of the tidal current generator.

Such lifting and lowering means 50, each of the guide rails 52 installed upright in the areas facing each other of the attachment facilities 100, and each one side is coupled to the shaft support 44, each The other side is provided on the upper surface of the movable body 54 and the accessory facilities 100, each provided with a roller (54A) guided to the guide rail 52, one end of the wire (56B) is coupled to the movable body (54) And a driver 56 including a driver 56A for lifting and lowering the support structure 40 through the movable bodies 54 by winding or unwinding the wires 56B. Here, the drive body 56A may be configured of an electric motor, a hydraulic motor, and the like. This drive 56A is configured to wind or unwind the wire 56B.

In this case, the raising and lowering means 50 may be composed of a rack and pinion instead of the guide rail 52 and the wire 56B, or may be composed of a hydraulic cylinder.

Referring to the operation process of such a lifting means 50, as follows.

1, 4 and 5, in order to lift the support structure 40 provided with the bidirectional generator 10, the drive body 56A of the drive unit 56 is operated to wind the wire 56B. In this process, the moving bodies 54 are moved upward.

As such, when the respective movable bodies 54 provided on both side shaft supports 44 of the supporting structure 40 are pulled up by the wires 56B, the rollers 54A provided on the movable bodies 54 are guide rails 52. Since it is moved to the top while being guided to, the support structure 40 coupled to the movable body 54 can be lifted.

Therefore, the operator can easily maintain or replace the two-way generator 10 in the lifted state.

6 is a view illustrating a bidirectional tidal current generating device using an accessory facility of a bridge according to a second embodiment of the present invention.

As shown in FIG. 6, the above-described implementation except that the support structure 40 including the bidirectional generator 10 and the turbines 30A and 30B is installed in the vertical direction on the outer wall of the accessory 100. Same as the example.

At this time, the guide rail 52 of the lifting means 50 is installed upright on the outer surface of the attachment facility (100). And, the guide rail 52 is preferably configured to guide the entire bottom portion 42.

As such, since the support structure 40 including the bidirectional generator 10 and the turbines 30A and 30B is installed in the vertical direction on the outer wall of the accessory 100, the tidal current generator according to the present invention has various accessory facilities. Can be applied to 100. That is, the support structure 40 with the bidirectional generator 10 and the turbines 30A and 30B is not necessarily installed between the pair of accessory facilities 100.

In the accompanying drawings, Figure 7 is a schematic front view showing a two-way tidal current generating device using the accessory of the bridge according to the third embodiment of the present invention.

As shown in FIG. 7, in the bidirectional tidal current power generation apparatus using the subsidiary facilities of the bridge according to the third embodiment, the bidirectional generator 10 and the first and second turbines 30A and 30B use one power generation set S1. At least two or more power generation sets S1 and S2 are arranged in succession at regular intervals in the vertical direction. At this time, it is preferable to sufficiently maintain the interval between the respective power generation sets S1 and S2, that is, the interval between the first turbine 30A and the second turbine 30B. This is because when the distance between the first turbine 30A and the second turbine 30B is narrow, a vortex is formed between each of the first turbine 30A and the second turbine 30B which rotate in opposite directions. This is because the rotation force may be lowered due to the interference.

The first and second turbines 30A and 30B constituting the power generation set S1 located on the upper side and the first and second turbines constituting the lower power generation set S2 adjacent to the upper generation set S1. 30A and 30B are each configured to rotate in opposite directions to each other. To this end, the first and second blades 34A and 34B of each of the power generation sets S1 and S2 are installed to rotate in opposite directions. This is because the turbines 30A and 30B of each of the power generation sets S1 and S2 adjacent to each other in the upper and lower portions are arranged in the opposite direction (engagement of the gears) by tidal current, with the respective power generation sets S1 and S2 arranged in succession. It is to improve the power generation efficiency by rotating smoothly). That is, when the turbines 30A and 30B of the power generation sets S1 and S2 adjacent to each other in the upper and lower parts are configured to rotate in the same direction, one turbine rotates forward by one tidal flow and one turbine When the reverse rotation, the interference flow of the tidal current is generated by the same direction rotation of each turbine (30A, 30B) is not smooth rotation of the turbine (30A, 30B), and thus the power generation efficiency is lowered. In order to prevent such a phenomenon, the respective turbines (each turbine disposed in the upper and lower parts) of the respective power generation sets S1 and S2 are rotated in opposite directions. For example, the left and right turbines 30A and 30B of the lower power generation set S1 are configured to rotate in opposite directions, and the left and right turbines 30A and 30B of the upper power generation set S2 are rotated. The left and right turbines 30A and 30B are configured to rotate in opposite directions, respectively.

As described above, each of the power generation sets S1 and S2 is disposed at a predetermined interval in the vertical direction, thereby improving power generation efficiency in a limited space. In the present embodiment, two sets of power generation sets S1 and S2 are applied, but the present invention is not limited thereto, and a plurality of power generation sets S1 and S2 may be disposed within a range allowed by space.

As shown in FIG. 8, when the plurality of power generation sets S1 and S2 are disposed on the support structure 40, the shaft support 44 between the turbines 30A and 30B located on the upper and lower sides thereof is provided. In the housing 12, an induction member 70A for guiding the tidal current to the turbines 30A and 30B of the power generation sets S1 and S2 is installed in the horizontal direction. At this time, on the upper and lower surfaces of the induction member 70A, a central guide slope 72A inclined toward each inlet side through which seawater flows from the central region is formed to guide the tidal current toward the upper and lower turbines 30A and 30B. That is, induction members 70A each having a central guide inclined surface 72A formed on each of the upper and lower surfaces thereof so as to be positioned between the turbine 30A of the lower power generation set S1 and the turbine 30A of the upper power generation set S2. Both ends of the) are fixed to the shaft support 44 and the housing 12, respectively.

In this way, an induction member 70A is provided between the upper turbines 30A and 30B and the lower turbines 30A and 30B of the respective power generation sets S1 and S2 to direct the flow of seawater to the respective turbines 30A and 30B. It can be induced effectively.

In addition, horizontal connecting members 80 for connecting and supporting the shaft support portions 44 on both sides are respectively provided at the upper end of each shaft support portion 44 so as to face the bottom portion 42 and face the inclined slope 46. In the region of the horizontal connection member 80 is an upper inclined surface 82 having the same or similar structure as the inclined surface 46, that is, the same or similar inclination angle as the inclined surface 46 is formed. The horizontal connection member 80 having such an upper guide inclined surface 82 guides the seawater to each turbine 30A, 30B together with the bottom 42 having the guide member 70A and the guide inclined surface 46. By doing so, it is possible to maximize the power generation efficiency.

As described above, each of the power generation sets S1 and S2 configured to rotate in opposite directions and maintaining a constant interval is arranged in succession, thereby improving power generation efficiency in a limited space. In the present embodiment, two sets of power generation sets S1 and S2 are applied, but the present invention is not limited thereto, and a plurality of power generation sets S1 and S2 may be disposed within a range allowed by space.

On the other hand, Figure 10 is a bi-directional power generation device according to the fifth embodiment shown in Figure 9 both ends (upper end and lower end) of the guide member 70B for guiding the current into each of the power generation set (S1, S2) shaft support portion It is fixed to the 44 and the housing 12 is installed in the vertical direction. The guide member 70B has a central guide slope 72B formed on both sides of the guide member 70B. These central guide slopes 72B are formed on both sides of the guide member 70B, respectively, so as to always guide the turbines 30A and 30B no matter where the current flows.
