A water discharge opening in the vicinity of the center, a central pipe with a held part on one side, a resource recovery opening for collecting or mining resources, and a resource opening closing means for closing the resource recovery opening at the end, and expanding and contracting by bellows One of the possible bellows pipes and the other end bellows pipe that can be expanded and contracted by the bellows, the resource recovery pipe as the lower layer water circulation means, and the water discharge opening can be closed through the inside of the central pipe An angle between the water surface and an internal penetrating member having a specific gravity smaller than that of water, a holding member for holding the held portion of the resource recovery pipe, a removable water tank for storing water discharged from the water discharge opening, and the water surface Floating structure for moving the resource recovery pipe to a horizontal position or a vertical position near the bottom of the sea or lake, natural energy power generation means such as wind power generation, and the resource Air exhaust means for exhausting the air above the internal penetrating member in the recovery pipe by the natural energy power generation means, imaging means and light emitting means provided in the vicinity of the resource recovery opening at the lower part of the resource recovery pipe, and the resource recovery Display means for displaying the output of the imaging means provided in the central pipe portion of the working pipe, and when the horizontal position, the resource collection pipe containing water and air inside the other bellows pipe is folded and the vertical position And moving the resource recovery opening to a vertical position near the seabed or lake bottom, the angle changing means slightly changes the angle with the water surface of the resource recovery pipe. The display means detects resources near the resource recovery opening, and exhausts air above the internal penetrating member from the air discharge opening in the resource recovery pipe, thereby removing the water surface in the central pipe from the central pipe. By moving the inner penetrating member to the upper part in the central pipe by moving it above the water surface, seawater or lake water is discharged out of the resource recovery pipe from the water discharge opening, and the water is collected by the water storage tank. The resource is stored by storing water discharged from the discharge opening and gradually moving the lower layer water of the seawater or lake water in the resource recovery pipe to the upper part and circulating the lower layer water of the seawater or lake water in the resource recovery pipe. After the resource detected from the recovery opening is inserted into the resource recovery tube and the resource opening closing means is closed and captured, the bellows of the other bellows tube that can be expanded and contracted at the other end is attached. The resource collection pipe is recovered by moving the resource recovery pipe to a horizontal position again while being stretched.
The central tube has a larger inner and outer diameter than the lower one bellows tube, and the inner and outer diameters of the lower one bellows tube are gradually made smaller.
A resource excavating means for excavating the sea bottom, the lake bottom, or the river bottom, or a nodule crushing means for crushing the nodule are provided below, outside, or below and below the resource recovery pipe near the sea bottom or the lake bottom. Further, the lower part, the outer part or the lower part of the resource recovery pipe and the external resource excavation means or the resource crushing means and the resource recovery opening are sealed in the external housing through the opening.

Prior to sampling or mining, the floating structure is held in a horizontal position with water and air contained in the resource recovery pipe, and can be expanded and contracted by the bellows at the other end during sampling or mining. On the other hand, the bellows tube is folded, and the resource collection tube is moved to a vertical position so that the resource collection opening moves the one bellows tube to the sea bottom or the lake bottom. Since the held portion of the central tube is on one side, the water discharge opening is located on the water near the air discharge opening and the central portion. After that, the angle changing means slightly changes the angle with the water surface of the central pipe, and the display means detects resources near the resource recovery opening, and the air above the internal penetrating member in the central pipe is By exhausting from the air discharge opening by the air exhaust means exhausted by the energy power generation means, the water surface in the central tube is moved above the water surface outside the central tube, and the internal penetrating member is moved to the upper portion in the central tube. Seawater or lake water is discharged from the water recovery opening through the water discharge opening and stored in the water storage tank. Accordingly, the resources detected by the display means are recovered by gradually moving the lower layer water of seawater or lake water in the resource recovery pipe upward and circulating the lower layer water of seawater or lake water in the resource recovery pipe. It is possible to capture the resources by inserting into the service tube and closing the resource opening closing means. The captured resources are housed in the resource recovery pipe, and seawater or lake water discharged from the water discharge opening is stored in the detachable water storage tank, so that the surrounding environment is not affected. After the captured resource is sufficiently accumulated and stored in the resource recovery pipe, the other end portion closes the water discharge opening of the central pipe before moving the resource recovery pipe to the horizontal position again. The other bellows tube that can be expanded and contracted is extended to the rear end by moving the one bellows tube having a resource recovery opening to a horizontal position by a chain and controlling the ballast water of the floating structure by the floating structure. The air collecting bellows tube which has been submerged and the other bellows tube is accumulated, the resource stored in the one bellows tube and the seawater or lake water is contained in the seawater or the lake water and floats on the seawater or the lake water by buoyancy. Float on the lake and collect the resources. Since the air discharge opening and the water discharge opening of the central pipe are closed before the resource recovery pipe is moved to the horizontal position again, the surrounding environment is not affected.

  A fourth embodiment of the resource recovery method according to the present invention is an embodiment of a deep seabed or lake bottom, and before the sampling or mining, the floating structure is positioned in a horizontal position with water and air incorporated in the resource recovery pipe. The first bellows tube is held and the other bellows tube, which can be expanded and contracted by the bellows at the other end during folding or mining, is folded, and the one side bellows tube is moved so that the resource recovery opening moves to the seabed or the vicinity of the lake bottom. A second step in which the resource recovery pipe is moved to a vertical position so that the air discharge opening and the water discharge opening in the vicinity of the center are positioned on the water; A third step of detecting a resource in the vicinity of the resource recovery opening by the display means with a slight change, and exhausting air above the internal penetrating member from the air discharge opening in the central pipe; The lower surface water of the seawater or the lake water in the resource recovery pipe is gradually moved to the upper part by moving the water surface above the water surface outside the central pipe and moving the internal penetrating member to the upper part in the central pipe. The resources detected by the display means are inserted into the resource recovery pipe through the resource recovery opening by circulating the lower layer water of seawater or lake water in the resource recovery pipe to capture the resource and to open the water discharge. A fourth step of discharging seawater or lake water from the mouth to the outside of the resource recovery pipe and storing it in the water storage tank; and after the captured resource is sufficiently stored and stored in the resource recovery pipe, the resource Before moving the recovery pipe to the horizontal position again, the water discharge opening of the central pipe is closed, the bellows of the other bellows pipe that can be extended and contracted is extended, and then the air discharge opening is closed and the end Part The one bellows tube having a source recovery opening is moved again to a horizontal position by a chain, and the ballast water of the floating structure is controlled to sink the floating structure to extend the bellows. Fifth step of floating the resource recovery pipe in the state in which the resource and seawater or lake water accumulated and stored in the bellows tube and floating on the seawater or lake water by buoyancy are floated on the seawater or lake water, and the resource is captured This comprises a sixth step of transferring the circular resource recovery pipe to the transfer site.
