  In order for a windmill moored fish reef consisting of a windmill pump device, a mixed breeding floor and a mooring device to directly use the rotational force of the windmill at sea, to operate effectively for a long period of time, it can withstand the severely fluctuating and offshore environment. This is a mechanical active means to reduce the large wind drag acting on the wind turbine in the setting posture, that is, to always keep the windmill upwind, to properly maintain the mixed growth floor that receives a large force from the sea tide Instead, it is required to use passive control means based on the configuration of the fish reef itself. However, in the case of a conventional windmill moored fish reef (Patent Document 2), for example, in a strong sea tide current area, due to an improperly connected part of the mooring line, the strong wind diverting action does not necessarily occur due to a predetermined strong wind, and It occurred before strong winds, and there was a problem that the pump capacity could be reduced and the windmill could be damaged.

Therefore, the present invention is a windmill moored fish reef in which a sea surface floating windmill drive pump device is penetrated and engaged at the center with an underwater floating mixed growth bed, and a mooring device is connected to the center .

Moreover, it is a windmill stationary artificial fishing ground where a plurality of the windmill moored fish reefs are arranged at predetermined intervals .

Moreover, surface water mixed with deep water for discharge of the individual wind turbines mooring reef of the wind turbine stationary artificial fishing grounds are marine production method for growing marine organisms.

Windmill moored fish reef as a solution of the present invention uses ubiquitous natural energy wind power on the ocean in severe environments, self-controls the operation and nutrients contained in the deep water discharged and pumped promote the growth of plankton, A large amount of seaweed can be grown with fish and nutrients that feed on this plankton. Therefore, if the stationary artificial fishing ground composed of moored reefs with high durability, operability, and stability reaches about 1% of the entire ocean, it will be possible to catch a large amount of fish, which means that protein foods can be used without environmental impact. It is possible to produce fish in large quantities, and to suppress the decline and deterioration of fish resources due to overfishing, and to revitalize the fishery.

The embodiments of the present invention will be described with reference to FIGS. 1 and 2.
Windmill mooring reef 1 consisting of wind turbine pump device 2 and the disk-shaped mixing growing bed 3 and mooring 4 which (FIG. 1), the number of meters in diameter, a predetermined distance rearward from the tower body 2 b the upper end is more steel length 100m Downwind type stall type windmill 5 that receives wind in the wind, a cuboidal buoyancy body 7 of several ten meters in which the tower body penetrates in the vertical direction, a rotating body of the windmill 5 and a transmission body 5b such as a transmission belt pump 8 formed of a pump casing 8e having through cooperation spur line one-side impeller 8c second opposing diameter of several meters at both ends of the impeller shaft 8b and supports the impeller shaft on either side discharge point 8d (Figure 2) ,

The water pipe 9 under the sea surface that is the steel pipe itself, the inner peripheral material receiver 10 that is surrounded and joined to the outer periphery of the water pipe, and the fin that is joined to the outer circumference of the water pipe that suppresses the inclination of the wind turbine pump device at a predetermined angular interval. 11 and the vertical direction of the disk-shaped stabilizer ballast 12 stable body made of a steel material mainly upset to suppress weight several hundred tons slope, and the total height 100m or more tower composed of said tower body 2b and conduit 9 A wind turbine pump device 2 floats on the sea surface where a plastic soft water guide pipe 13 having a diameter of several meters and having a diameter of several meters close to the specific gravity of sea water is joined at the lower end of the pipe body,

A concentric arrangement of a hollow annular inner peripheral material 14 having an inner diameter greater than the seawater specific gravity, an inner diameter equal to or greater than the outer diameter of the conduit pipe, and a hollow annular outer peripheral material 15 having an underwater specific gravity substantially equal to the seawater specific gravity. A sea surface floating structure connected to the outer peripheral material and the soft surface material via a rope, which is tack-bonded to the inner material and the outer material, the inner and outer peripheral materials, the connecting material and the steel material, and is formed into a surface shape with the soft surface material 16 covering the entire surface. Is suspended below the pump 8 of the pump device by a plurality of small buoyancy bodies 17 and is larger than the seawater specific gravity of the overall average specific gravity, and descends from the inner peripheral member 14 through which the water guide pipe 9 is engaged to the outer peripheral member. A windmill moored fish reef 1 is configured by the mooring means of the mooring means 4 and the submarine sinker 18 via the relay buoyant body 4b described later . Incidentally, the sinker 18 is not completely fixed to the seabed, if an excessive external force acts, may be the small sliding is allowed.

When the mooring reef moves from the sinker 18 to a predetermined horizontal distance, the windmill moored fish reef is affected by the horizontal force of the seawater drag acting on the underwater surface of the pump device and the mixed growth floor and the wind drag acting on the windmill. The cable is tensioned, the horizontal component of the tension is balanced with the horizontal force of the mooring cable connected to the inner peripheral member 14 of the mixed growth floor , and the vertical component is buoyant and fishing caused by partial subduction of the relay buoyant body 4b. Fit. The mooring line is inclined at approximately 45 degrees determined by the depth of the installation water and the length of the mooring line.
In addition, the buoyancy of the entire substantial volume portion of the buoyancy body 7 is equal to or greater than the total weight of the wind turbine pump device.

As mentioned above, this windmill moored fish reef is centered on the seabed sinker 18 in the direction of the vector synthesis of the ocean current drag and wind drag due to the steady ocean current and intermittent slow and direction changing wind, the ocean current drag direction and the wind drag direction. The mooring line always floats on the sea surface corresponding to a horizontal predetermined radius of approximately 70% of the length of the mooring line . However when currents drag and wind drag is equal to the opposite direction is Jo浮within the predetermined radius. When the wind direction changes , the wind turbine pump device 2 that penetrates and engages the inner peripheral member 14 to which the mooring line is connected and is substantially vertically self -supported, receives the wind drag force received by the downwind stall type wind turbine 5 when the tower 2b for acting as a motor Mento, center is horizontally rotating the inner peripheral member 14 the entire pump unit, i.e. the wind turbine is to perform the air direction control directed to the windward.
Further, the entire windmill reef is rotated to a position corresponding to the leeward of the submarine sinker .
Then, the rotational force of the windmill rotates the impeller 8c via the rotation shaft, the transmission belt 5b, and the impeller shaft 8b, continues the pump operation, and discharges the seawater in the pump to the outside. Along with this discharge, deep water at the lower end of the soft conduit 13 is sucked and rises.

If the wind turbine rotation speed becomes excessively high at a wind speed higher than the specified value during a storm, the stalled wind turbine of the downwind type will stall and the wind will escape, so the wind turbine rotation will decrease, that is, the wind drag will decrease and the wind turbine pump device will A predetermined pump operation is continued even under strong winds while maintaining a substantially vertical position without tilting greatly. Then, while the deep deep water released from the pumped water flows on the mixed growth bed 3 to the outer periphery, it is mixed with the light surface water by the vertical movement of the growth floor material 16 by the multiple small buoyancy bodies 17 following the wave motion. Of mixed water, flowing down from the outer periphery and spreading into a horizontal layer with a predetermined depth of light.
It is also possible to adjust the length of the branch of each small buoyancy body 17 according to the temperature difference between the surface layer water and the deep layer water and change the shade gradient of the growing bed .
As described above, this moored fish reef exhibits a wind direction control and a strong wind response action with a simple configuration and a passive control mechanism, and continues a predetermined pump capacity operation while suppressing damage to the windmill and the like.

The mooring line is a buoyant body relay type mooring method in which the mooring line is not directly connected to the inner peripheral material 14 of the mixed growth floor 3 but connected to a buoyancy body floating on the sea surface by being connected via a rope longer than the radius of the growth floor. When the mooring method for more detail, the method as shown FIG. 1, 浮状sea level by connecting the synthetic fibers mooring 4 spanning approximately 1500m linked to the seabed sinker 18 spanning the depth approximately 1000m thereunder buoyant body, for example a relay 4b over 100 cubic meters, i.e. volume with 100 tons of buoyancy, as the buoyant body is sea浮状away from the outer periphery of the front Symbol growing bed, longer relay cord than the radius of the growing bed to be A relay buoyant type mooring that connects the bifurcated end of 4c to both ends of the diameter of the inner peripheral member 14, and connects the other end to the lower part of the relay buoyant body to connect the mixed growth bed 3 to moor the windmill moored fish reef. Is the method.
Incidentally, the mooring lines 4, connecting cord 4c, relay buoyant body 4b, and engaging fastening means of the one point fixing constituting the seabed sinker 18 is referred to as a mooring device. In this case, downward-out component of the tilt tension generated in mooring due wind pressure balance in buoyancy due to partial precipitation inclusive relay buoyancy, will be only the horizontal component is act on the inner peripheral member, the inner peripheral receiving inner peripheral material of wood under side can be simplified 10, the wind direction control sexual windmill pumping apparatus, than when directly connected by mooring sinkers and the inner peripheral member without passing through the relay buoyant body, toward I will go up. In addition, the buoyancy body 7 of the pump device can be reduced in size . Note that the horizontal buoyancy position of the buoyancy body 7 and the center line of the tower body 2b may not be aligned so that the pump device is substantially vertical at a predetermined wind speed . Furthermore, the mixed growth floor having the same structure larger than the mixed growth floor is under the growth floor, penetrating the water conduit of the wind turbine pump device, and the level of the inner peripheral material is lower than the outer peripheral material, that is, the mixed growth floor A multi-layer mixed breeding floor disposed in a convex shape opposite to the floor, that is, an inverted shade shape, is also preferable. In this case, the deep water mixed water that has flowed down from the outer periphery of the upper growing bed flows from the periphery of the lower growing bed to the center thereof while mixing with the surface water, and flows out from there. Further, a three-layer mixed growing bed in which a growing bed larger than the lower growing bed is disposed below and substantially in the same manner as the upper growing bed may be used.
