  The present invention supports a heavy-weight rotating body so that it can rotate stably and with high precision around a vertical axis, and cancels or greatly reduces its thrust load. A floating generator that can reduce the load as much as possible is desired.

  The problem of wind power generation is the floating type that can solve the adverse effects on the environment due to low frequency, the shortage of the power generation time due to the wind conditions, or the occurrence of wind noise damage due to excessive rotation due to typhoons and gusts A generator is anxious.

  In the present invention, a vertical wing blade for windmills is arranged in a circular manner on the upper end side of a vertical shaft in a vertically upright state, a circular cylindrical body is connected to a lower end side of the vertical shaft, and the circular cylindrical body is inserted. A levitation bearing that supports the rotating body in a floating state together with the buoyancy chamber and the vertical shaft by sharing the thrust load of the vertical shaft by the buoyancy that the liquid in the buoyancy chamber that contains the liquid for generating buoyancy acts on the buoyancy chamber And a generator to which rotational force is transmitted via a drive mechanism mounted on a vertical shaft. Further, wind turbine vertical wing blades separated in a circular arrangement were fixedly arranged in a standing state in a plurality of stages in the axial direction of the vertical axis.

  The levitation generator according to the present invention shares the vertical axis thrust load by buoyancy and supports the rotating body so that it can rotate in a floating state together with the buoyancy chamber and the vertical axis, and the rotational force is transmitted through the drive mechanism. This is a floating generator consisting of a generator that is supported by a heavy-weight rotating body that is pivotally supported around a vertical axis in a stable and highly accurate manner to offset or drastically reduce its thrust load. The thrust load of the rotating body could be reduced as much as possible even in a light wind.

  Furthermore, by arranging the vertical blade blades for windmills, separated in a circular shape, in a standing state in a plurality of stages in the axial direction of the vertical axis, it was possible to suppress the generation of low frequencies and prevent damage from wind noise. Furthermore, by attaching the wind turbines at each stage to the star-shaped steel plate for connecting the wind turbines, a floating generator that can sufficiently withstand strong winds such as typhoons can be provided.

  The levitation generator according to the present invention uses the rotational force of the wind turbine connected to the top and connected to the top and bottom, and the buoyancy of the floating dock fixed to the bottom of the vertical main shaft to load the equipment related to power generation. By dramatically reducing the load and smoothly transmitting the rotational force to the generator, it was possible to extend the power generation time zone and prevent equipment troubles.

It is front sectional drawing of the AA arrow of FIG. 2 which shows the Example which concerns on this invention. It is a plane sectional view of the BB arrow of Drawing 1 showing the example concerning the present invention. It is a top view of the CC arrow of FIG. 1 which shows the Example which concerns on this invention.

  An embodiment according to the present invention will be specifically described below with reference to FIGS.

  Embodiments will be described below. However, the present invention is not limited to the descriptions, procedures, and functions.

  In addition, in order to maintain clarity in the drawings in this application, equipment other than equipment related to power generation, or members related to reinforcement in the power generation building are not shown, and equipment and parts related to functions related to implementation of the present invention. Only the accessories are shown.

  FIG. 1 illustrates the process of generating power by the influence of the present invention on a generator by showing a cross-sectional front view.

  The tank filling water 40 is poured into the floating tank 2 located in the power generation building 1 and the vertical main bearing floating dock 7 is put therein. At this time, buoyancy is generated in the floating dock top lid 10 whose center is circularly opened so that the center passes through the vertical spindle 14 and the vertical spindle 14 welded and fixed to the floating dock bottom plate. Further, the floating water tank 2 is attached with a floating dock steady ring 3 to achieve stable rotation.

  The wind turbine 36 connected to the top of the vertical main shaft 14 in which buoyancy is generated, the star-shaped steel plate 35 for connecting the wind turbine, and the wind turbine cradle 34 receive the buoyancy of the vertical main shaft 14 so that the load attached to the wind turbine cradle 34 Since the load applied to the receiving main caster 32 is drastically reduced, the windmill 36 can be smoothly rotated and rotated without making a squeaking noise.

  Further, when the buoyancy of the vertical main bearing floating dock 7 is too strong or too weak, the structure can be adjusted by raising and lowering the filling water level, and the lowermost part is a vertical main bearing ring 12 installed at the center of the floating water tank 2. It is made up of a structure mounted on.

  The buoyancy starts to work on the vertical main bearing floating dock 7 by starting to fill the floating tank filling water 40, but when the vertical main shaft 14 floats by 20mm as measured, the floating range is stopped by stopping the water level of the floating tank filling water 40 Is kept constant, and unevenness in vertical vibration of the vertical spindle 14 is suppressed as much as possible.

  The levitation water tank 2 is installed at the lowest position of the facility and is embedded in the anchor concrete 17 and the invert reinforcing bar 18 in the power generation building 1, and the lower part thereof is a water tank root winding concrete 19 reinforced by the root winding reinforcing bar 20. The unit low plate steel 13 and the levitation water tank 2 that are put on the anchor concrete 17 are connected directly at the upper part, so that the lateral displacement is achieved. By maintaining the center of the power generation equipment without causing it, the vertical spindle 14 can be kept in a smooth rotating state.

  The levitation water tank 2 is connected directly to the unit low plate steel 13 covered on the anchor concrete 17 so that the water tank upper cover 4 and its reinforcing frame 5 are not directly connected to the vertical main shaft 14 and use the upper cover connecting flange 6. By doing so, the structure can be removed freely.

  Further, the vertical main bearing floating dock 7 fixed to the lowermost part of the vertical main shaft 14 is a facility that is completely integrated with the vertical main shaft 14, and the internal structure of the vertical main bearing floating dock 7 is inserted from the upper part to reinforce the lower part. The vertical main shaft 14 connected to the steel plate, the floating dock reinforcing bar 8, the floating dock hanging brace 9, the floating dock upper lid 10 and the upper lid reinforcing frame 11 are configured.

  The vertical main bearing floating dock 7 and its upper part can be separated by the vertical main shaft flange 15, and the upper part can be cut off in the same manner, so that the subsequent maintenance can be easily performed.

  The buoyant water tank 2 generates the buoyancy by transmitting the characteristics of the water in the ground to the vertical main bearing floating dock 7, and generates power from the wind turbine 36 connected to the vertical main shaft 14 located above the generator 21. However, when the buoyancy is too strong, the overcasting caster 29 works to prevent the vertical spindle 14 from lifting too much, thereby minimizing vertical vibration of the vertical spindle 14. Keep it to the limit.

  In FIG. 2, the vertical main shaft main gear 27 connected to the vertical main shaft 14 rotates the generator 21 by transmitting the rotational force transmitted by the vertical main shaft 14 to the gear 24 with the generator shaft. The generator is surrounded by a permanent magnet 23 and is fixed to the generator fixed wall 25 and the generator fixed floating wall 26. By rotating the generator 21, the coil winding blade 22 generates electric power. Represents the situation.

  By showing the plane of the power generation building 1 in cross section, the vertical main shaft main gear 27 and the generator shaft-equipped gear 24 related to power generation are in close contact with each other, and the vertical main bearing floating dock 7 disposed below the vertical main shaft main gear 27 and the floating water tank. 2 shows the upper lid reinforcing frame 5 and the presentation of the water tank upper cover 4 and the water tank fixing plate 16.

  Further, in the power transmission control panel 28 shown in FIG. 2, the measurement of the amount of power consumed and sold or the amount of power purchased is grasped. Only the unit entrance 42 shown in the figure is used for entering and exiting the personnel at this time.

  A description will be given of the power generation of the windmill support 34 and the windmill 36 or the star-plate steel plate 35 for connecting the windmill according to the present invention, which is shown in FIG.

  The blades of the wind turbine 36 which are welded and fixed on the wind turbine coupling star-shaped steel plate 35 fixed on the wind turbine support 34 fixed to the vertical spindle 14 with buoyancy, and for wind turbine coupling in the same manner. The blades of the star-shaped steel plate 35 and the windmill 36 are fixed on the stack, and the rotational force is increased as a connected windmill by stacking them in five stages. When the wind turbine 36 and the star-plate steel plate 35 for connecting the wind turbine and the vertical main shaft 14 are separated by regular repair or maintenance, they are separated by the frame joint flange 41. At this time, the load receiving main caster 32 is fixed on the main caster track board 33.

  Since the blades of the wind turbine 36 may be insufficient in strength against excessive wind pressure such as typhoon, the strength and balance of the entire wind turbine are balanced by the suspending brace 37 in addition to the reinforcing rib 38 attached to the blade portion for reinforcement. The structure is such that the lateral vibration of the vertical main shaft 14 is stopped by the function of the anti-sway wheel 30 to be maintained. At this time, the load receiving main caster 32 receives the levitation force and is synchronized with the windmill while being lifted 20 mm from the main caster track bed 33 Rotate.

  Further, the vertical main shaft 14 is connected to the upper portion through the opening portion by the vertical main shaft joint flange 15 from the uppermost vertical main shaft mech lid 39 of the wind power generation equipment to the vertical main bearing floating dock 7 disposed at the lowermost portion. A rainwater protection hat 31 is attached to prevent leakage of accumulated rainwater.

  Since the wind turbine 36 of the present invention is a horizontal rotation method, a rotational force is exerted on the vertical main shaft 14 by receiving the wind blowing from the direction of 360 degrees with the concave blade 44, but on the opposite side across the vertical main shaft 14 Since the convex surface blade 45 is located, the rotational force generated by the concave surface blade 44 may be scraped by receiving the wind pressure.

  However, the concave blade 44 has a structure that receives the wind pressure on its surface. However, the convex blade 45 functions to cut the wind for the convex surface, and winds the cut wind to blow the gap. As a result, the wind pressure received by the convex blade 45 becomes minute, and the rotational force acts on the windmill 36.

FIG. 3 is a plan view as viewed in the direction of arrows C-C in FIG. 1, and shows a mounting relationship between the wind turbine coupling star-shaped steel plate 35 that supports the wind turbine 36 and the wind turbine cradle 34 attached to the lower portion thereof. .
Currently, the popularization of wind power generation as a renewable energy is recommended, but the low frequency human body / environment that accompanies the widespread use, wind noise damage caused by the wind, Problems such as stability can be solved by the present invention.

  By preventing the generation of low frequencies, which is a problem with wind power generation, it has become possible to install in places such as private residential areas and factory zones, and to generate power without generating noise. It became possible to sell the remaining power after private consumption by generating electricity in the private residential land.

  According to the present invention, by fixing a facility only for power generation to a vertical main bearing floating dock 7 installed on water, this facility has a levitation force, and the weight of the power generation facility itself is the levitation force. Will be offset.

  With existing wind power generation, it is said that power generation is impossible without wind power at a wind speed of 5 m. However, if the wind turbine loses its own weight, no rotational load is generated, so power generation at a wind speed of 2 to 3 m is possible.

  The ability to generate electricity with small winds extends the average daily generation time period and increases the amount of power generation, greatly increasing the utilization and installation of airborne power generation.

In the present embodiment, the present invention is applied to a Darrieus wind turbine, but the present invention can also be applied to all wind turbines having a vertical rotation axis, for example, Savonius wind turbine, cross flow wind turbine, S-type wind turbine, paddle wind turbine, and the like.
