Abstract

PROBLEM TO BE SOLVED: To solve problems in a deep water intake device using wind power, wave power, or the like, wherein low water intake efficiency is caused by the irregular generation of energy, a large amount of deep water is difficult to intake, and a installation place for water intake equipment is limited. SOLUTION: This deep water intake device is provided with a float body which floats on the sea water and has a water storage part in it, at the bottom of which an upper end opening is attached, and an intake pipe extended so as to position a lower end opening at a sea water bottom part. The deep water intake device takes water without using power from the outside by means of the structural dead weight of the float body, and is moved to an objective sea water region for installation by using the float body capable of self- navigation, or by towing the float body with another boat.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a deep water intake apparatus for pumping deep water by utilizing the weight of a floating structure such as an oil tanker, a waste oil tanker, a pontoon or an elastic membrane bag.

[0002]

2. Description of the Related Art Deep water is rich in nutrients.
The use of deep water is drawing attention and its demand is expanding. However, since deep water is in a deep seawater area with a depth of 200 m or more, facilities for pumping deepwater are rapidly deepened from the land where the intake facility is provided, from an economic viewpoint such as the length of an intake pipe. Is desirable.
Therefore, the location conditions of facilities that can take in deep water were very limited.

On the other hand, pumping deep water also requires external power, and a method using natural energy as external power has been proposed. For example,
Japanese Patent Application Laid-Open No. 4-190727 discloses a deep water pumping device utilizing wind energy.
Japanese Patent Application Publication No. JP-A-2005-115122 discloses apparatuses for pumping seawater or the like using the energy of waves.

[0004]

However, since natural energy such as wind and waves is generated irregularly, the efficiency of water intake is low, and it is difficult to withdraw a large volume of deep water. The present invention has been made in order to solve such a problem, and provides a device that can take in deep water without limiting the water intake place and can take in deep water without requiring external power. It is intended to be.

[0005]

According to a first aspect of the present invention, there is provided a floating body which floats on a sea surface and has a water storage portion therein, and an upper end opening is provided at a bottom of the floating body. A water intake pipe extending so that the lower end opening is located at the bottom of the seawater, and a deep water intake device that takes in water without using external power by utilizing the structural weight of the floating body.

According to a second aspect of the present invention, there is provided a deep water intake apparatus in which the floating body is capable of navigating by itself or towed by another ship, moved to a target seawater area, and installed.
Further, in claim 3, the floating body is a transport ship or a waste transport ship, and in claim 4, the floating body is a box-shaped pontoon,
According to a fifth aspect of the present invention, there is provided a deep water intake device in which the floating body is a large capacity elastic membrane bag.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. 1A and 1B are explanatory views showing a first embodiment of the present invention, in which FIG. 1A shows a state before deep water intake, and FIG. 1B shows a state after deep water intake.
In FIG. 1A, a water reservoir 2 for deep water 8 is provided inside a floating body 1. Deep water 8 is provided at the bottom 3 of the floating body 1.
A switch 4 is provided for allowing the water to flow into the inside, and the switch 4 is connected to an upper end opening 6 of a water intake pipe 5, and a water intake 7 is formed at a lower end of the water intake pipe 5 so that deep water is formed. 8
There is an extension to the bottom of the seawater.

In FIG. 1B, when the opening / closing device 4 is opened, most of the water storage portion 2 inside the floating body 1 is located below the sea surface, so that deep water 8 flows in from the water intake 7. Then, it is stored in the water storage part 2 in the floating body 1. Next, if the switchgear 4 is closed, the pumped deep water 9 does not flow out of the floating body 1 and can be brought back to land.

FIG. 2 is a schematic explanatory view showing a second embodiment of the present invention. In this embodiment, the floating body 1 is capable of navigating by itself or towed by another ship and moved to the target sea area and installed there. Specifically, the floating body 1 is an oil tanker or a waste transport ship 11. In the figure, an intake pipe 5 is connected to the bottom 3 of an oil tanker or a waste oil tanker 11. The structure and functions other than those described above are the same as those described in the first embodiment.

FIG. 3 is a schematic explanatory view showing a third embodiment of the present invention. In the present embodiment, the floating body 1 is a box-shaped pontoon 12. In the figure, an intake pipe 5 is connected to the bottom 3 of the pontoon 12. The structure and functions other than those described above are the same as those described in the first embodiment.

FIG. 4 is a schematic explanatory view showing a fourth embodiment of the present invention. In the present embodiment, the floating body 1 is an elastic membrane bag 13. In the figure, the bottom 3 of the elastic membrane bag 13 is shown.
Is connected to an intake pipe 5. The structure and function other than those described above are the same as those described in the first embodiment.

Although not shown in the drawings, as other embodiments, various types of pools, fishing ponds, aquariums and other leisure facilities for humans, storage facilities for marine products, seafood and the like can be used by utilizing the deep water stored inside the floating body. Culture facilities may be provided.

[0013]

According to the present invention, there is provided a deep water intake apparatus which floats on a sea surface and has a water storage portion therein, an upper end opening is provided at the bottom of the floating body, and a lower end opening is located in the sea bottom layer. A deep water intake device that includes a water intake pipe extending to the floating body, and that takes in water without using external power by utilizing the structure's own weight of the floating body, wherein the floating body is capable of self-traveling or other A deep water intake apparatus characterized by being towed by a ship, moved to a target seawater area, and installed. Therefore, unlike the conventional water intake device, the water intake place is not limited. In addition, since water is taken using the weight of the floating body, there is no instability such as natural energy such as wind and waves, so that stable water can be taken at all times.
