In order for a windmill moored fish reef consisting of a windmill pump device, a mixed breeding floor and a mooring line to directly use the rotational force of the windmill on the ocean, to operate effectively for a long period of time, it can withstand the harsh and harsh environment of the ocean. This is a mechanical active means for setting posture, that is, directing the windmill to the upwind at all times, properly maintaining the mixed growth floor that receives a large force from the sea tide, and reducing the large wind drag acting on the windmill during storms Instead, it is required to use passive means based on the structure 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 improper connection part of the mooring line, a strong wind diverting action does not necessarily occur at a predetermined wind speed, and the predetermined It occurred before the wind speed, and there was a possibility that the pump capacity could be reduced and the windmill could be damaged.

Therefore, the first aspect of the present invention is a wind turbine pump device driven by wind power, a mixed growth bed that mixes the deep water discharged from this pump device with surface water and waves, and is connected to this mixed growth bed at a point on the seabed. A windmill moored reef consisting of anchoring mooring lines,

Further, the third invention is configured as a windmill stationary artificial fishing ground in which one or more moored fish reefs are moored, and the fish breeding production is effectively performed on a large scale in a predetermined sea area. Is called.

Further, the fourth aspect of the present invention is a stationary artificial fishing ground constituted by a windmill pump moored fish reef, wherein the windmill pump device of each fish reef is driven by the wind and the deep water is discharged and the upper surface of the mixed growth floor is The deep-sea water is mixed with the surface water while flowing to the surroundings, and the marine life is nurtured and produced by the second step in which the mixed water spreads from the surroundings and the third step in which the mixed water nurtures marine organisms. It is a method to do.

A windmill moored fish reef as a solution of the present invention is a fish that feeds on plankton as nutrients contained in deep water that is pumped and released using ubiquitous natural energy wind power offshore in severe environments. Can grow in large quantities.
Therefore, if the fixed artificial fishing ground composed of moored reefs with high durability, operability and stability reaches about 1% of the entire ocean, large-scale fishing will be possible. It is possible to produce fish in large quantities without losing fish resources due to overfishing and to revitalize the fishery.

The best embodiment of the present invention will be described with reference to FIG.

Windmill moored fish reef 1 comprising a windmill pump device 2, a plate-like mixed breeding floor 3 and a mooring line 4
(FIG. 1) shows a single or a plurality of stall type wind turbines 5 or variable pitch type wind turbines 5 or a tower having a diameter of several tens meters from the upper end of the tower, which is a steel pipe having a diameter of 100 meters or more. Down-wind type stall type or variable pitch type windmill that receives the wind, the wind direction blade 6 that is formed of a frame material, a cloth sail, and a face material, and is provided on the opposite side of the windmill, and the tenth through-joining in the longitudinal direction of the steel pipe The cuboid buoyancy body 7 of the meter is linked to the rotating shaft of the windmill and the transmission belt, and supports the single-sided impeller having a diameter of several meters facing both ends of the rotating shaft parallel to the rotating shaft of the windmill and the rotating shaft, and discharges it. The pump 8 which is a casing having a mouth, the water guide pipe 9 below the sea surface which is the steel pipe itself, the inner peripheral material receiver 10 which surrounds and joins the outer periphery of the water pipe, and the guide which suppresses the inclination of the wind turbine pump device. Around the water tube 1000 m at the lower end of a wind turbine propon unit water conduit with a total height of 100 m or more, which is composed of fins 11 joined at 90 degree intervals and a disc-shaped stable ballast 12 mainly made of iron material with a weight of several hundred tons to suppress vertical shaking and tilting. A windmill pump device 2 that floats on the sea surface where plastic soft water guide pipes 13 having a diameter of several meters and having a seawater specific gravity close to each other are joined,

A concentric arrangement of a hollow annular inner peripheral member 14 having an underwater specific gravity adjusted to be larger than a seawater specific gravity and having an inner diameter equal to or greater than the outer diameter of the conduit pipe and a hollow annular outer peripheral member 15 having an underwater specific gravity substantially equal to the seawater specific gravity A sea surface floating structure that is tack-bonded to the inner and outer peripheral materials, the connecting material, and the tonnage material and is formed into a planar shape by the soft surface material 16 over the entire surface, and is connected to the outer peripheral material and the soft surface material via the rope. The basin-like mixed growth bed 3 that is suspended and held below the pump of the pump device by a plurality of small buoyancy bodies 17 that is larger than the seawater specific gravity of the overall average specific gravity and slightly inclined from the inner peripheral material to the outer peripheral material, The inner peripheral member 14 and the water guide tube 9 are connected by penetrating engagement, and below the inner peripheral member, the annular inner peripheral member receiver 10 that surrounds and joins the outer periphery of the water guide tube is disposed radially at a predetermined angle. The inner peripheral member 14 contacts a plurality of cylindrical or conical rollers. Thus, there are two bifurcated ends of a synthetic fiber mooring line 4 of about 1500 m which is connected to a seabed sinker 18 or an anchor having a water depth of about 1000 m and fixed at one point at two locations on both ends on the outer diameter side of the inner peripheral material. Connect to each other to form a fish reef.
In addition, the structure in which an inner peripheral material contacts the whole periphery of the annular inner peripheral material receiver 10 both in parallel with the axial direction of the water guide pipe and with a cylindrical roller arranged horizontally in the radial direction. In the case of a downwind wind turbine, it is assumed that there are no wind vanes 6.

The wind mooring fish reef is subjected to the horizontal force of the ocean current drag acting on the underwater surface of the pump device and the mixed breeding floor and the wind drag acting on the wind turbine etc., and the mooring line becomes tense when moving from the sinker 18 to a predetermined horizontal distance. The horizontal component force of the tension balances with the horizontal force, and the vertical component force balances with the buoyancy generated by the partial sinking of the buoyancy body 7. The mooring line has an inclination of about 45 degrees determined by the depth of the installation water and the length of the mooring line. The inner circumference material receiver 10 is an antagonistic point of the vertical component force, and is also a stopper that prevents the inner circumference material from being pulled down by the mooring line, that is, the mixed growth bed is lowered. The buoyancy corresponding to the total substantial volume of the buoyancy body is not less than the total weight of the wind turbine pump device.

As mentioned above, this windmill moored fish reef is in the direction of the vector synthesis of the ocean current drag and wind drag due to the steady current and intermittent slow and direction changing wind.
The wind turbine pump device 2 that is always on the sea surface with a predetermined radius centered on the seabed sinker 18 and that is penetratingly engaged with the inner peripheral member 14 to which the mooring line is connected and is vertically self-supporting is provided by the action of the wind vane 6. The entire device is rotated around the inner peripheral material 14 to the windward, that is, the wind direction is controlled to direct the windmill to the windward,
The rotation of the windmill rotates the impeller through the rotation shaft, the transmission belt, and the impeller shaft, continues the pump operation, and discharges the seawater in the pump to the outside.
With this discharge, the deep layer water at the lower end of the soft water conduit 13 is sucked and rises. In the case of a downwind type windmill or a downwind type stall type windmill, the wind direction is controlled by the moment of the wind resistance received by the windmill with respect to the tower body.

If the wind turbine rotation speed becomes excessively high at a wind speed higher than the predetermined during a storm, the stall wind turbine, variable pitch wind turbine, downwind variable pitch wind turbine or stall wind turbine will cause a pitch change or stall and let the wind escape. As a result, the windmill rotation is reduced, that is, the wind drag force is lowered, and the windmill pump device is kept substantially vertical, and the predetermined pump operation is continued even under strong wind.
Then, while the deep deep water that has been discharged and discharged flows on the mixed growth floor 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 plurality of small buoyancy bodies 17 that follow the waves. Of mixed water, flowing down from the outer periphery and spreading into a horizontal layer with a predetermined depth of light.
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 not directly connected to the inner peripheral material of the mixed growth floor, but is connected to the inner peripheral material via a rope longer than the radius of the growth floor and connected to a buoyant body floating on the sea surface. The type mooring method is also good. In this case, the downward component of the inclination tension generated in the mooring line due to wind pressure or the like balances the buoyancy caused by partial subsidence of the buoyant body, and only the horizontal component acts on the inner peripheral material. The peripheral material receiver 10 can be simplified or eliminated, and the wind direction controllability of the wind turbine pump device is improved. In addition, the buoyancy body of the pump device can be reduced in size.
Furthermore, in this case, the mixed growth floor larger than the mixed growth floor is under the growth floor, penetrating the water conduit of the wind turbine pump device, and the inner peripheral material level is lower than the outer peripheral material, that is, A multi-layer mixed growth bed arranged in a downward convex shape opposite to the mixed growth bed, that is, an inverted shade shape may be used. 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.

The windmill stationary artificial fishing ground is constructed by arranging the above-mentioned windmill moored reefs at intervals of several hundred meters.

The marine organism production method uses the above-mentioned stationary artificial fishing grounds to obtain marine organisms, plankton, fish and seaweeds by pumping and discharging deep water from a windmill moored fish reef, mixing deep water and surface water, and nutrients contained in the mixed water. It is a method of training.

In addition, depending on the depth of the sea area where the fish reef is installed, the ocean current speed and the size of the mixed growth bed,
The mooring line may be connected to a predetermined part of the pump device or both of the device and the mixed growth bed.
In the case of twin wind turbines, the shape of the wind turbine tower body is T-shaped or bifurcated and at the tip, and in the case of trio wind turbines, it is cross-shaped or trifurcated, and two or three wind turbines are arranged at each tip. A relay shaft of the transmission belt of each windmill is disposed at the intersection.
Further, it is possible to reduce the size of the impeller by increasing the speed of the impeller by increasing the diameter of the transmission belt wheel between the windmill rotating shaft and the impeller rotating shaft or by adding a single-stage speed increasing device. It is good to attach a lightning protection device to the windmill pump device of the windmill moored reef, or to attach a restraining device to the transmission belt to stop the rotation of the windmill in the case of installation or repair. A stop may be provided.

In addition, in order to transmit the ocean current drag acting on the long soft conduit directly to the mooring line,
The middle part of the soft conduit and the middle part of the mooring line may be connected with a rope, and a weight may be attached to the lower end of the soft conduit. Also, a pump housing buoyancy body type pump device in which the pump is installed inside the buoyancy body and two or more outlets are provided on the side surface may be used.

A mooring comprising a mixed water discharge windmill pump device and a small breeding bed, which is provided with a surface water suction pipe with a regulating valve, which connects the lower surface of the buoyant body of the pump device and a water guide pipe penetrating vertically. Fish reef is also good. In this pump device, a rotating impeller mixes and discharges surface water from above while sending deep water from below to an outlet.
It is also possible to replace the transmission belt with a bevel gear and a transmission shaft, and to replace the horizontally installed impellers on the upper and lower sides.
In addition, a mixed water discharge mooring windmill pump device that leaves only the inner peripheral material connected to the mooring line and excludes the breeding floor may be juxtaposed with the stationary artificial fishing ground, or an artificial fishing ground may be formed by a plurality of pump devices.

In addition, in the case of a fish reef of a pump device in which the wind turbine of the wind turbine pump device is replaced with a normal wind turbine without strong wind countermeasures, a two-link switching mooring type that actively copes with strong wind by adding a heating separation device, that is, a mixed breeding bed The middle point of the rope connected to two locations of the inner circumference of the cable and the predetermined point of one mooring cable connected to the seabed sinker are connected via a heating connector related to the heating separation device, and the tip of the mooring cable May be a two-connection switching mooring type fish reef that is fixedly connected in a slack shape to a predetermined part of the side of the buoyant body or the side of the water conduit away from the central axis.
The synthetic fiber cord portion where the hooks are joined to both ends of the connector is coated with a heat generating element of the heating / separating device together with a water-resistant heat insulating material, and the heating / separating device includes the heating element, an open / close switch, a battery, wind speed or windmill rotation. The sensor, the information processing controller, and the wiring connecting these sensors are placed on the buoyancy body of the pump device except for the heating element.

The operation is as follows: When the wind is strong, the controller sends a conduction signal to the switch according to a value greater than a predetermined value detected by the sensor, and the heat generated by the heating element due to the current from the battery heats the synthetic fiber portion at a high temperature. Reduce
This heating connector under tension is broken.
Due to this heat rupture, the tension acting on the mooring line is switched to the two sides of the buoyant body side, which is fixedly connected to the tip, and as a result, the entire wind turbine pump device rotates by a predetermined angle around the connection point of the buoyancy body side part. In other words, the windmill is deflected from the direction of the strong wind. The broken heating coupler is updated.
Further, a plurality of ultraviolet light emitting diodes connected to a power supply system including a power generation device, a timed opening / closing switch, and a battery may be arranged on the mixed growth floor.

In place of the mooring line of the windmill moored fish reef, the bundling parts that bundle the ropes joined to the four corners of the frame material stretched with the face material are connected, and the sea current moves as a resistor that suppresses movement due to wind drag. A drift-type windmill fish reef and a drift-type artificial fishing ground composed of many windmill reefs are also good.

In other words, increase the horizontal distance between the tower and the shaft core,
Also, a moored fish reef of a normal windmill front windmill type pump device disposed at an end of a windmill rotating shaft extending forward from a tower which is a steel pipe body above the buoyancy body may be used.
The wind resistance of the wind turbine during strong winds surpasses the wind direction acting force of the wind vane, and the pump device
A state in which the wind turbine is deviated from the direction of the wind and the rotation of the wind turbine is reduced by rotating it by a predetermined angle around the axis of the tower conduit with the inner periphery of the mixed growing floor connected to the mooring line as a semi-fixed point Continue pumping.
In the case of a wind turbine type pump device that is not a downwind type, the tower body is moved forward, and in the case of a down window type wind turbine type pump device, the tower body is moved backward, that is, the horizontal axis of the tower body and the shaft of the water conduit is horizontal. It is also possible to increase the distance and to suppress the over-rotation speed of the wind turbine in a strong wind and to improve the wind direction controllability by the wind drag received by the wind turbine. In this case, the upper and lower transmission belts are linked by a horizontal connecting shaft.

In addition, an intake / exhaust water valve and a pipe having a predetermined length may be provided at the upper and lower parts of the buoyancy body 7, and in this case, the draft can be adjusted deeply when the wind turbine pump device is assembled offshore. .

In addition, a wind turbine blade having an internal space that is not an internal enhancement but has an internal framework and a surface material has an internal space provided with a communication hole that communicates with each other, and further includes at least the base of the blade and the most A plurality of communication holes that communicate the inside and the outside may be provided in the surface material of the distant internal space, and the inside may be a communication space. Due to the arrangement of the communication holes, even when the blades are sequentially put into the sea during the assembling work on the ocean, seawater can enter the internal space, and damage to the blades can be prevented without causing a pressure difference between the inside and the outside.

Two-link mooring passively controlled mooring winds constructed with power generation and power transmission equipment, except for the mixed growth floor and soft water conduit, leaving the inner peripheral material connected to the mooring line from the mooring reef of the ordinary windmill A power plant is also good.

Further, the present invention is not limited to the above embodiment, and can be appropriately changed in design.

It is the schematic which shows the windmill moored fish reef of this invention.
