Abstract

PROBLEM TO BE SOLVED: To juxtapose cultivation facilities above sea level and the like and sea level difference generating set utilizing low tide level sea water energy, and reduce the arrangement costs thereof, by constructing a part of a coastal area as waters surrounded by a levee. SOLUTION: A water gate basic bottom board 8 is constructed on a water ground G1 line in a levee, which is dug out deeper than a low water line W2 of a tide and a coastal area ground G line. A horizontal shaft water-turbine 4 is arranged through a water wheel bearing 5 in a position where the vertical slide of the water gate door 3 of this water gate basic bottom board 8 may not be disturbed. When the water gate door 3 is lowered to the upper surface of the water gate basic bottom board 8, a water gate 2 is closed, and when the water gate door 3 is lifted to a position of about 2/3 of the diameter of the horizontal shaft water-turbine 4, a sea water outflow/inflow area C is constructed in the lower part of the water gate 2. Sea water is led to flow into and out while rotating normally and reversely the horizontal shaft water-turbine 4. The shaft 6 of the horizontal shaft water-turbine 4 is connected to a transmission 18 connected to a generator motor M1 through a rotary shaft 17 and the like. Then, the rotational force of the normal and reverse rotation of the horizontal shaft water-turbine 4 is corrected by the transmission 18 thereby, the generator motor M1 is uniformly rotated so as to generate power.

At that time, the floodgate is closed and the high tide phenomenon of the tide starts, and the water level outside the embankment becomes the water level inside the embankment. When the water level is slightly higher, slide the floodgate door up to a predetermined position to open the floodgate and carry out the inflow of seawater into the embankment.When the high tide phenomenon ends and the water level inside and outside the embankment reaches the same level, Close the lock.

On the other hand, the hydroelectric generators will be shut down during the tide ebb phenomena and during the low tidal range of about 15 days a month, resulting in lower power generation. The purpose of the installation is different from that of the commercial power equipment because it is a private power generator that is installed together with the purpose.

便にする。A seawater inflow / outflow area is constructed at the lower part of the caisson, and the space above the seawater outflow area is divided into two large and small areas by middle dividing walls.
A sluice door is installed to control the opening and closing of the seawater inflow and outflow area along the middle dividing wall in the other small vacant rooms by installing sand in the large room and ensuring the gravity of the caisson sluice gate by injecting sand into the large room. The construction of a caisson-type sluice gate constructed at a position facing an embankment, with a vacant room having an entrance and exit for a worker who installs a transmission device for the rotation starting force of a horizontal shaft turbine installed in an entrance area, facilitates construction of the sluice gate.

る。According to the present invention, at a low tide, a relatively shallow coastal sea area where a part of the seafloor ground is exposed is a coastal sea area unsuitable for carrying out sea surface aquaculture projects. The inflowing coastal waters are not suitable for shellfish and seaweed (grass) cultivation business because the seabed is polluted, and the utilization is low.However, due to good construction conditions such as embankment construction, part of the coastal waters To provide a marine aquaculture project implementation environment by digging the constructed coastal sea area to a certain depth, and to reclaim other parts of the land using dredged sediment. Providing the site of the facility will expand the aquaculture business establishment environment and increase the production of marine products.

生産コストの軽減が計られる。Implementing a sea-farming business in a water area surrounded by a dike is less likely to cause wave damage due to typhoons and weathering, etc., while increasing productivity by implementing a management-type aquaculture business, but on the other hand, seawater pollution and seawater in the open sea In the case of outbreak of pathogenic bacteria, it is necessary to close the sluice gate.Therefore, it is necessary to carry out the earring for the management of the water quality in the levee including the water quality of the shore aquaculture facilities that use the water in the levee as a water source. The demand for electric power, such as pumping seawater, is high, which puts pressure on the production costs of the aquaculture business.However, the utilization of seawater flow energy is being expanded, and an in-house power generation facility is installed. Supply system is established and the cost of producing marine products is reduced.

あり設置コストの軽減が計られる。When a dike is to be constructed in a coastal area having a deep water where the sea surface aquaculture business can be carried out, the construction method of the breakwater that is conventionally carried out is advantageous, but the construction of the sluice gate is underwater work, and the construction is complicated and the construction cost is increased. Is expensive,
The caisson-type sluice gate according to claim 4 can be manufactured on an FD ship (caisson-manufactured ship), and can be transferred to the installation site after the power generation facility is installed. Reduction is measured.

It is a coastal sea area, but the utilization of the coastal sea area where the ecosystem has been destroyed due to the accumulation of red soil particles on the sea floor and the ecosystem has been destroyed due to, for example, the land development of Okinawa Prefecture and other reasons, has been reduced. However, the river basin is extended to the coastal sea area by embankment construction, multiple sedimentation dams are constructed in the extended river basin to carry out sedimentation treatment of pollutants, and the river levee is used to extend the river basin. It is possible to provide an environment for implementing aquaculture business by constructing a restricted water area by extending the embankment to a water area where river water does not flow from the country, and increasing the production of marine products.
