Description

Detailed Description of the Invention B) Field of Industrial Application The present invention relates to a flowing water upwelling block for upwelling bottom water, accumulated mud, etc. from the ocean floor, lake bed, river bed, etc.

■ Problems that the invention aims to solve When looking at seafood and the ocean, there are 1 things that move seawater.
There are 1) caused by ocean currents, 1) tidal currents, 1) wave currents, and 1) density currents, etc. However, the flow speed of seawater on the seabed is extremely slow compared to that on the sea surface, and the movement of unnecessary floating materials that accumulate on the seafloor, Purification is extremely difficult, and the abnormal growth of plankton caused by this is one of the causes of the Red 1 Tide, causing not only difficulties in aquaculture but also widespread environmental degradation, such as the annihilation of tuna. In addition, the current situation is that the accumulation of organic and inorganic substances on lakebeds and riverbeds is causing deterioration of the water environment.

As mentioned above, the present invention aims to achieve purification of the bottom where the flow rate is slow by using natural forces with a simple structure, and the present invention will be explained in detail below with reference to the drawings. . FIGS. 1 and 2 show a perspective view and a side view of the upwelling block according to the present description, in which (a) four wall plates 1-1 to 1-4 are provided in the central portion 2;

(b) The wall plates 1-1 to 1-4 have their lower ends placed on a fixing base 3 and their upper ends provided with reinforcing pieces 5.

(c) The tip end 7 of the center portion 2 is provided to penetrate the fixing base 3.

In such a configuration, a formwork such as a steel plate is provided, concrete is poured into the core with the reinforcing bars removed, for example, and solidified as one, and then the space between the wall panels 1-1 to 1-4 is made of steel plates, reinforced plastic plates, etc. The reinforcing piece 5 is integrally fixed with screws or the like. Alternatively, as shown in FIGS. 4 and 5, the center portion 2, the wall plates 1-1 to 1-4, and the fixing base 3 may be manufactured separately and combined into one body at the time of installation.

0 Functions and Examples The flowing water upwelling block of the present invention having the above structure can be installed, for example, in an area where the purification of the seabed is desired, by lifting it with a crane or the like through the support hole 6 and lowering it sequentially from the sea surface to the seabed. However, at this time, the through hole 4 provided in the fixed base 3 serves to reduce the resistance of the seawater, making it possible to install it at a desired location. In addition, since unnecessary suspended matter is deposited on the bottom sediment of the seabed area where the block is desired to be installed, when installing the block, the conical or cylindrical tip 7 protruding from the fixed base 3 should be placed on the bottom sediment. The fixed base 3 prevents the block from moving when it hits the soil, and also prevents it from being buried in soft ground and preventing it from falling over. Its size depends on the degree of softness of the ground and the flow rate of seawater on the seabed. The size can be set to an arbitrary size.

Now, the function when installing this block is that when the seawater moves as described above, the seawater that flows oppositely between two adjacent wall plates 1-1 to 1-4 flows into the center part 2. Therefore, since the distance between the wall plates is narrow, seawater has the effect of being pushed upwards above the block. At this time, suspended matter existing on the bottom soil rises upward together with seawater.

■ Effects of the Invention Next, the effects of the present invention will be described. For example, in tuna farming, even if leftover food from feeding is deposited on the seabed, when the seawater moves, it upwells together with the seawater at the location where the block is installed, and it is removed from the seabed. In addition to natural purification, the uneaten food that rises up becomes food for a variety of fish in the natural world, and as a result, it creates a fish-attracting effect that attracts a large number of fish, and the installation of a large number of blocks can also be expected to create a fish reef effect. The flow between the installed blocks causes a flash phenomenon, which contributes to the disturbance and upwelling of floating objects on the sea floor.

Further, for example, installation in seaweed cultivation has the effect of preventing sedimentation of fertilizer and making it possible to improve the efficiency of fertilization.

(F) Other Embodiments As shown in FIG. 3, even if the wall board is composed of three wall plates 1-1 to 1-3, the objective can be achieved although the effect will be somewhat reduced.

Furthermore, another embodiment shown in FIGS. 4 and 5 will be explained.
FIG. 4 is a perspective view, and FIG. 5 is an exploded view of the main parts. As can be understood from the perspective view of Fig. 4, wall plates 1-1~
In 1-4, the lower end is thicker than the upper end so that water can easily flow from the lower end to the upper end of the block, and it can achieve the intended purpose even when installed on the seabed where the flow velocity is particularly slow. can be reached.

Furthermore, in FIGS. 4 and 5, when manufacturing the center part 2, a groove part 8, such as a U-shaped iron plate embedded at the same time, is provided, and the wall plates 1-1 to 1-4 are provided with guides that fit into the groove part 8. 9 and a protrusion 10 are provided, the two are integrated into a ring, and the reinforcing piece 5 and fixing base 3 are attached to the upper and lower ends of the wall plate with screws or the like through the reinforcing piece attachment holes 11 and screw holes 13, respectively. screw 14
The desired purpose can be achieved even if the parts are fixed together.
