DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial upwelling generator installed on the seabed for upwelling generation.

[0002]

2. Description of the Related Art Photosynthesis is performed by using upwelling generated by an artificial upwelling device installed on the seabed to elevate bottom water rich in nutrient salts for phytoplankton to the light layer. By promoting the action and promoting the growth of phytoplankton, and by increasing and collecting zooplankton collected in the phytoplankton and collecting fish, the basic productivity of the sea area is enhanced and a favorable fishing ground is established. An apparatus or method for doing so has been proposed.

Therefore, the following inventions are given as prior art documents related to the present invention. That is, Japanese Unexamined Patent Publication No.
This is an artificial upwelling generation structure described in Japanese Patent No. 15275.
The gist is to install short auxiliary impact solids on the upstream and downstream sides of a long main impulse solid installed in a direction orthogonal to the tidal current. A plurality of the auxiliary impulse solids are provided so that the closed side faces the main impulse solid, and the open side formed by the three-sided partition plate portions is erected in the tide direction. The height of the partition plate of this auxiliary partition plate is lower than that of the partition plate of the main partition, facilitating installation in the deep water area, ensuring structural stability, and covering a wide area. It is an invention intended to ensure the upwelling of water.

[0004]

The invention of the above-mentioned prior art document (hereinafter referred to as the present invention) has the effect of achieving the generation of artificial upwelling flow and facilitation of installation. However, the present invention is a combination of a main impulse solid and an auxiliary impulse solid having an integral structure, and has a structure for generating an upwelling flow by the partition plate and each partition plate portion. Therefore, it is difficult to change the weight of the main thrust solid and the auxiliary thrust solid, and it is difficult to change to the combination with the highest upwelling in consideration of the tidal current of the coastal sea area, the undersea condition, and the seabed. There are challenges. The present invention also aims to generate upwelling currents. Therefore, there is a problem that it does not have the function as a fish reef.

[0005]

In view of the above, the present invention is superior in that it ensures an upward flow inside the cylindrical column and effectively exerts the upward advection / diffusion function of the nutrients of the seabed layer. The following configuration is adopted with the intention of providing a good fishing ground, structurally simple, facilitating production, and achieving cost reduction.

That is, the artificial upwelling generator of the present invention comprises a pyramid-shaped mount framed by a frame-constituting member made of shaped steel, steel or the like, and a large number of cylindrical columns obliquely installed on the mount. It is composed of.

Further, the present invention adopts the following structure for the purpose of securing a large number of inner shelves and exhibiting the function as a fish reef by providing a large number of cylindrical columns on the gantry.

That is, the artificial upwelling generator of the present invention comprises a triangular pyramid-shaped pedestal, which is framed by the pedestal constituent materials such as shaped steel and steel, and an inclined standing formed in a state where the gantry is laid down on its side. It is composed of a large number of cylindrical columns obliquely provided facing each other on the hanging portion.

[0009]

In the present invention, assembling of the gantry and assembling of a large number of cylindrical columns are, in principle, constructed on a land such as a revetment by using heavy machinery and are framed and installed on the seabed.
3 will be mainly described. That is, after installing a base member using a heavy machine (suspending and assembling, which will be omitted below) on the seawall, a front view (indicated by an arrow in the figure) at a proper position on both ends of the base member is shown. (See FIG. 6) An a-shaped hanging hem member is provided by means of bolting, attachment means such as welding and binding (hereinafter referred to as attachment) (see FIG. 6). In the illustrated example, there are six locations, but the number is not limited. When this standing hem member is provided,
A large number of cylindrical columns are horizontally provided between the base and the standing hem member and in the longitudinal direction of the base (direction of the arrow) (see FIGS. 7 and 8). At the stage where the many cylindrical pillars are installed horizontally, the many cylindrical pillars are fixed to the base by a numbering wire or the like (an example). After that, after the hanging inner frame members are obliquely installed on the respective hanging hem members, a vertical transfer member is provided between the hanging inner frame members to fix the hanging inner frame members (see FIG. 9). ). Using the fixed outer surface (surface) of the hanging inner frame member and the upper surface (surface) of the base member, a large number of cylindrical columns are obliquely provided, and the cylindrical columns are opposed to each other (Fig. 10). After that, a hanging outer frame member is provided so as to protect the periphery of a large number of obliquely arranged cylindrical columns, and the hanging outer frame member and the hanging inner frame member are fixed to complete the process shown in FIG. The artificial upwelling generator is constructed.

After that, the installation on the seabed will be carried out. Specifically, several artificial upwelling devices are loaded on the carrier (see FIG. 11). After that, it is transported to a predetermined position using a doug boat, and when it reaches the predetermined position, it is installed on the seabed using a crane ship, and preferably, it is installed intermittently as shown in FIG.
In this way, a large number of cylindrical columns are installed obliquely on the confronting surface of the gantry having a triangular pyramid shape installed in a recumbent shape, and a large number of cylindrical columns are laid horizontally on the base of the gantry (tiered stacking). To be done.
Therefore, the slope with the highest upwelling can be easily designed for the tidal current on the installation seabed. Specifically, since the upward flow is strengthened by the through hole and the wall part due to the assembly of the cylindrical column, and the upward flow is generated in the upper and bottom parts of the wall, the upward flow occurs inside the cylindrical column, and the bottom layer is generated. The upward advection / diffusion function of nutrients is effectively exerted. In addition, by installing many cylindrical columns in the center of the gantry, it has many inner shelves and has an effective function as a fish reef even for bottom and middle-layer fish. Further, the present artificial upwelling device can be arranged in a row or intermittently so as to promote continuous upwelling.
The constituent members of the gantry, the order of assembling the gantry, and the oblique installation and transportation of a large number of cylindrical columns are merely examples and are not limited.
