In some cases, the diameter may be very large, such as several hundred to 1000 m. The guide base 20 and the driving wheel 12 have the same center diameter. The ultra-large diameter can be implemented in a typical large lake.

  The moving wheel 12 is a hollow body, and superconducting magnets (one of the superconducting systems) a are built in both sides of the inside. Reference symbol b denotes a coil for levitation, guidance, and propulsion, and this coil b is disposed at a position in the groove of the guide base 20 across the circumferential direction.

In FIG. 10, reference numeral 45 denotes an installation base that is the seabed of the coastal sea area. The base support 45 is erected so that a center support leg 46 at the center and outer peripheral support legs 47 arranged on the outer periphery of the center support leg 46 extend to the sea. Has been deployed.
A bearing body 48 is fixed on the center support leg 46, and a rotary shaft 49 having a vertical axis is rotatably provided on the bearing body 48. A driving gear 50 is attached to the rotating shaft 49, and a power generation gear 51 driven by the driving gear 50 is provided to drive a generator 52 that is one of the power generation systems. The installation base 45 may be a float floated on the surface of the water, or may be flat as shown in FIG.
Note that the rotation shaft 49 may have a horizontal axis shape or an oblique axis shape. In this case, it is possible to arrange a plurality of power generation devices in a small space and generate a large amount of power generation.

  On the outer periphery of the rotating shaft 49, a rotating disc 54 consisting of two upper and lower plates is attached in the middle, and an anchor disc 55 is attached to the upper end. An inner diameter side base portion of an arm 56 arranged so as to form a cross when viewed from above is attached to the turntable 54. An annular driving wheel 57 is attached via the outer peripheral ends of these arms 56.

In some embodiments, the driving wheel 57 may be an integral annular ring. In this embodiment, as shown in FIGS. 8 to 10, the driving wheel 57 is divided in the circumferential direction into arcuate drive units 58... 58... Are connected in a chain form by connecting the front and rear with vertical chain pins 59.
The arm 56 is connected using a specific one of the chain pins 59. The chain pin 59 is configured to allow the front and rear drive units 58 to move by a slight angle and to always return to the original posture by the operation of a return spring (not shown).

  Reference numeral 61 denotes a reinforcing member, which connects the arms 56 to each other to construct the arm 56 into a planar arm body. Reference numeral 62 denotes a suspension member, which is stretched between the anchor board 55 and the arm 56 and is armed. The body is suspended from the rotation shaft 49. The suspension member 62 is adjustable in length. In addition, the structural members such as the arm body and the driving wheel 57 can be made of a light and strong material such as an aluminum alloy or a titanium alloy.

  65 is a guide base, and the base 65 is formed in a flat circular shape with a cross-sectional groove shape using concrete, resin, metal, etc., and its diameter Dx is 5 to 10 m, or a large diameter of 50 to 100 m. In some cases, the diameter may be very large, such as several hundred to 1000 m. The guide base 65 and the driving wheel 57 have the same center diameter. The ultra-large diameter can be implemented in a representative large lake in addition to the illustrated sea area.

  The moving wheel 57 is formed of a hollow body, and propulsion superconducting magnets (one of the superconducting systems) a and a are built in both sides of the inside. “b” represents a propulsion coil, and this coil “b” is disposed in the groove facing position of the guide base 65 in the circumferential direction. The coil b is normally used for both levitation and guidance. In this embodiment, the coil b is only used for propulsion, and the levitation is provided separately. That is, a levitation superconducting magnet c is provided at the center bottom of the guide base 65, and a levitation permanent magnet d is provided at the bottom of the driving wheel 57 corresponding thereto. Reference numeral 66 denotes an auxiliary wheel for low speed, which can roll on the guide base 65 until a constant initial speed is obtained and until it is decelerated and stopped.

The driving wheel 57 is rotationally driven in the direction of the arrow by the generation of a moving magnetic field by the superconducting magnet a for propulsion and the like and the propulsion coil b as in the linear propulsion system. When the driving wheel 57 is at a low speed, it is rotated by rolling by the auxiliary wheel 66, and when it reaches a certain speed, the floating superconducting magnet c provided at the bottom of the guide base 65 is actuated to activate the floating permanent magnet on the driving wheel 57 side. It is rotated at high speed without resistance by the levitation force due to d. A floating permanent magnet d may be provided at the bottom of the guide base 65, and a floating superconducting magnet c may be provided on the moving wheel 57 side. Since the driving wheel 57 has a continuous shape in the circumferential direction, there is no air resistance generated at the tip of the linear Shinkansen, and the rotating member such as the arm 56 is also designed to have a very low air resistance. Several central generators 52 can be installed, and a large rotational energy is generated by selecting a very large diameter Dx as the driving wheel 57, and a large amount of power is generated by rotating the central generator 52 at high speed with the energy. Easy to get. The supplied power for levitation and propulsion can be one using natural energy such as a solar power generation device 67 and a wind power generation device 68 as shown in FIG. As for the left and right runout when the moving wheel 57 rotates at a high distance, the fact that the inner peripheral configuration such as the arm 56 and the reinforcing member 61 functions as a restricting means is used.
The driving wheel 57, the magnets a, c, d, the coil b, and the like constitute a circular drive system.
Moreover, the generator 52 can also be arranged so as to be driven by a gear that is inscribed or circumscribed to the driving wheel 57 as shown in FIG.

As shown in FIG. 9, a center support leg 46, a bearing body 48, a rotating shaft 49, a driving gear 50, a power generating gear 51, a generator 52, a rotating disk 54, an anchor panel 55, a reinforcing member 61, a suspension member 62, and the like. It is also possible to arrange such that the generator 52 is driven by a gear that is inscribed or circumscribed on the moving wheel 57 by omitting the inner peripheral structure of the guide base 65 and only the outer peripheral portion of the moving wheel 57.
In addition, when the inner peripheral configuration is omitted, induction power generation may be performed by the winding coil 69 around the driving wheel 57.
Furthermore, as shown in FIG. 12, the power generation amount is doubled if the levitation / propulsion means shown in FIG. A double row is two or more rows.

Further, a pedestal 71 is installed near the base of the center support leg 46 in the coastal sea area, and a pipe is erected from the center as a center support leg. The lower end of the rotating shaft 49 is extended into the pipe, and a stirring blade 72 is provided on the outer periphery thereof. And aeration means 73 can be combined to facilitate the purification of seawater.
This can constitute the same water purification promoting means for the inside of the aeration tank of the sewage treatment plant.
