In the case of a deep seabed or lake bottom, one embodiment of the circular resource recovery pipe is, for example, a circular resource that can be adjusted to a length of 1 kilometer, and the inner and outer diameters of the circular resource overlap each other. Measure the depth of the seabed or bottom from the sea or above the lake before laying, and make the circular resource recovery pipe overlapping in multiple layers the measured length of the seabed or bottom. A circular resource recovery pipe is filled with seawater or lake water, and is laid to the bottom of the sea or the lake through the wedge at the bottom of the circular resource recovery pipe. Further, in the case of a deep seabed or lake bottom, another embodiment of the circular resource recovery pipe is, for example, a circular shape that can be adjusted to a length of 1 kilometer, and the inner and outer diameters are overlapped in multiple layers with increasing depth. The resource recovery pipe and the central part can be adjusted in length. The lower the inner and outer diameters are, the lower the inner and outer diameters are. The circular resource recovery is overlapped by the multiple layers. The lower part of the service pipe reaches the bottom of the sea or lake and is laid to the bottom of the sea, lake or river. In the first and second embodiments, the capacity of water that moves the water surface in the circular resource recovery pipe to a position above the water surface outside the circular resource recovery pipe is compared with the capacity of water discharged from the water discharge opening. Increase the inner shape of the upper part of the circular resource recovery pipe as much as possible. A stopper for restricting the movement of the circular internal penetrating member having a central opening is provided in the circular resource recovery pipe to restrict the amount of water discharged from the water discharge opening. The upper part of the resource recovery pipe has a larger inner and outer diameter than the lower part, and the lower part gradually reduces the inner and outer diameters of the intermediate part of the circular resource recovery pipe to the inner and outer diameters of the circular resource recovery pipe. Reduce the inner and outer diameter of the collection opening to the extent that biological resources or mineral nodules can pass through. If it is made smaller, the circulating water flow can be accelerated and the efficiency of sampling or mining is improved. A configuration in which a plurality of the resource recovery openings are provided at the lowermost part of the circular resource recovery pipe is also conceivable.

The floating structure on the sea, on the lake, or on the river may include a power generation means and a power storage means of natural energy such as wind power, sunlight, and wave power, and may be configured to move by the power. Resources can be easily mined by providing resource excavating means or resource crushing means for excavating or crushing resources on the bottom or outside or near the bottom or outside of the bottom of the circular resource recovery pipe or near the bottom of the river. Further, the resource excavating means or resource shredding means and the resource recovery opening are sealed and incorporated in a housing provided with a lower opening except for the lower part. Therefore, the cut excavated or crushed is sealed in the housing and the mining efficiency is mined by the fast water flow circulated by the resource recovery opening having a small inner and outer diameter, so that the surrounding environment is not affected.

The resource excavating means or the resource crushing means is operated by an operation member that is adjustable in length and can operate the lower part of the resource recovery pipe. In this case, the upper part is penetrated by the lower part of the resource recovery pipe and the external operation member. In the housing having a lower opening. The source excavation means or the resource crushing means is hermetically sealed, and the excavated or pulverized resources are mined into the resource recovery pipe through the resource recovery opening and from the water discharge opening of the resource recovery pipe. The drained water is stored in a detachable water tank, so it does not affect the surrounding environment. When the resource excavating means is provided on the bottom or near the bottom or near the bottom or bottom of the circular resource recovery pipe, the resource excavating means is configured to move, for example, from the top of the seamount in a relatively shallow water area to the slope. In particular, a cobalt rich craft having a high cobalt content is excavated, and the inorganic resources of the cobalt rich craft are precipitated on the lower surface of the circular resource recovery pipe through the resource recovery opening. Even when mining organic resources such as methane hydrate organic resources, rare earth mud, seawater hydrothermal deposits, etc., the resource is deposited on the bottom surface of the circular resource recovery pipe. When mining the organic resources of methane hydrate, a configuration is also possible in which an electric cooling device is provided on the lower surface of the circular resource recovery pipe. When the organic resources of methane hydrate are vaporized, the vaporized methane hydrate is recovered through the central opening of the circular internal penetrating member. The air exhaust means exhausts the air above the internal penetrating member with, for example, electric power of natural energy such as wind power, sunlight, and wave power. The circular resource recovery pipe is configured such that the volume of water that moves the water surface in the circular resource recovery pipe to the upper part of the water surface outside the circular resource recovery pipe is relatively larger than the capacity of the water discharged from the water discharge opening. If the inner shape of the upper part is made, air will not be inserted from the water discharge opening. Even if air is inserted, the circular internal penetrating member has a central opening. Therefore, when the internal penetrating member is moved to the upper part of the circular resource collecting pipe, the sea surface in the circular resource collecting pipe is used. Alternatively, air inserted from the water discharge opening that intervenes the lake surface or river surface and the lower surface of the internal penetrating member can be sucked by the central opening. In addition, when the resource is mixed in the water discharged | emitted from the said water discharge opening, the said resource is collect | recovered from the said water tank. Although the resource recovery pipe has been described in the embodiment with the circular outer diameter, any shape such as a square can be used.

It is possible. The circular resource recovery pipe has a resource recovery opening and an adjustable length lower resource recovery pipe, and an upper resource recovery pipe that has water discharge openings at the top and bottom of the surface of the sea, lake or river. A configuration in which the circular resource recovery pipes are combined at the time of laying in a two-body configuration is also possible. In addition, the annular floating member is a resource recovery ship, and the upper part of the two-part resource recovery pipe has a larger inner and outer diameter than the lower part so that the annular floating member can be attached to and detached from the resource recovery ship. A configuration is also possible in which a source recovery pipe is coupled to the upper resource recovery pipe, and the resource recovery vessel of the annular floating member is moved by, for example, the power of natural energy.

  The collected or mined resources are connected to the resource recovery vessel via the air outlet and the bellows pipe, and the circular resource recovery tubes are filled with air and the resources or seawater or lake water via the ladder. After the circular resource recovery pipe is floated on the sea, lake or river, the circular resource recovery pipe is moved horizontally on the sea surface, lake surface or river surface, and the circular resource recovery pipe is transferred to the transfer site. Transfer to recover resources. When the sea floor or the bottom of the lake is deep, connect the lower end of the circular resource recovery pipe to collect resources in the sea or lake in the circular resource recovery pipe or collect resources on the sea floor or near the bottom of the circular resource. The resource recovery opening is closed and the resources below the circular resource recovery pipe are captured in the circular resource recovery pipe, and then the air discharge opening is substantially the same as the circular resource recovery pipe. Connecting the container of the volume or connecting with the resource recovery vessel through the air discharge opening and the bellows tube, the circular resource recovery tube is filled with air and the resource collected or mined with the resources and the seawater or lake water The circular resource recovery pipe is floated on the sea or lake. At this time, the upper part of the resource recovery pipe has an inner and outer diameter larger than that of the lower part, and the lower part gradually reduces the inner and outer diameters of the circular resource recovery pipe intermediate part. The weight of the part is reduced, and it is easy to pull up when floating through the clasp. Thereafter, the circular resource recovery pipe is moved horizontally on the sea surface or the lake surface, and the circular resource recovery pipe is transferred to a transfer place to recover the resources. The resource collecting pipe having a plurality of overlapping pipes, the length of which can be adjusted and the inner and outer diameters of which are smaller toward the lower part, is made to overlap again and then the resources are recovered. In addition, the resource recovery pipe, which is composed of a bellows tube whose length is adjustable and whose inner and outer diameters become smaller toward the lower side, is made short again, and the resource is recovered.
