The bottom of the sea or the bottom of the lake or the bottom of the resource recovery pipe near the bottom of the lake or outside the bottom or outside of the bottom of the sea or the bottom of the lake or the bottom of the river is excavated. Further, resource excavating means or resource shredding means and resource recovering openings below or outside or below the resource recovery pipe are hermetically sealed in the external housing through the opening.

Before collection or mining, the floating body structure holds the resource recovery pipe in a horizontal position with water and air contained therein, and can be expanded and contracted by a bellows at the other end during collection or mining. On the other hand, the resource recovery pipe is moved to a vertical position in order to fold the bellows pipe and move the resource recovery opening to the seabed or the vicinity of the bottom of the lake. Since the held portion of the central pipe is on one side, the water discharge opening is located on the water near the air discharge opening and the central portion. Thereafter, the angle changing means slightly changes the angle with the water surface of the central pipe, and the display means detects the resources in the vicinity of the resource recovery opening, and the air in the upper portion of the inner penetrating member in the central pipe is naturally The air is exhausted from the air discharge opening by the air exhausting means exhausted by the energy generation means, the water surface in the central pipe is moved to the upper side than the water surface outside the central pipe, and the internal penetrating member is moved to the upper part in the central pipe. Sea water or lake water is released from the resource recovery pipe from the water discharge opening and stored in the water storage tank. Therefore, the resource detected by the display means is recovered by gradually moving the lower layer water of seawater or lake water in the resource recovery pipe upward to recover the seawater or lower layer water of lake water in the resource recovery pipe. It is possible to insert in the working pipe and close the resource opening closing means to capture the resource. Since the captured resources are stored in the resource recovery pipe and seawater or lake water discharged from the water discharge opening is stored by the removable water storage tank, the surrounding environment is not affected. After the captured resources are sufficiently accumulated and stored in the resource recovery pipe, the water discharge opening of the central pipe is closed before moving the resource recovery pipe to the horizontal position again, and the other end thereof The floating body structure is provided with a resource recovery opening at the rear end of the stretchable other side of the bellows tube having a resource recovery opening, which is moved again by a chain to a horizontal position to control the ballast water of the floating body structure Sink the object and extend the bellows, while the air in the bellows tube and the resources stored in the accumulation and storage of the one bellows tube and the seawater or lake water are contained and float on the seawater or lake water. It floats on lake water and recovers the resources. Since the air discharge opening and the water discharge opening of the central pipe are closed before moving the resource recovery pipe to the horizontal position again, the surrounding environment is not affected.

The fourth embodiment of the resource recovery method according to the present invention is a deep seabed or lake bottom embodiment, wherein the floating body structure has a horizontal position with water and air contained inside a resource recovery pipe before it is collected or mined. First step to hold the other, and collapsible by the bellows at the other end during collection or mining while folding the bellows tube and moving the resource recovery opening to the seabed or near the bottom of the lake A second step of moving the resource recovery pipe to a vertical position and positioning the air discharge opening and the water discharge opening near the central portion on the water, and the angle changing means determines an angle with the water surface of the central pipe A third step of detecting the resources in the vicinity of the resource recovery opening by the display means with a slight change, and air in the upper portion of the inner penetrating member in the central pipe is exhausted from the air discharge opening The lower surface water of seawater or lake water in the resource recovery pipe is gradually moved to the upper side by moving the inner penetrating member to the upper side in the central pipe by moving the water surface of the central pipe to the upper side than the water surface outside the central pipe. The resource detected by the display means by circulating seawater or lake water in the resource recovery pipe is inserted into the resource recovery pipe from the resource recovery opening to capture the resource and the water discharge opening The fourth step of releasing 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 accumulated and stored in the resource recovery pipe, the resource Before moving the recovery tube back to the horizontal position, close the water discharge opening of the central tube and stretch the bellows of the other end, while stretching the bellows of the bellows tube, and close the air discharge opening and end In the department The one bellows tube having a source recovery opening is moved to a horizontal position again by a chain and the ballast water of the floating body structure is controlled to sink the floating body structure to extend the bellows, and the air of the bellows tube and the one side The fifth step of floating the resource recovery pipe above the seawater or lake water with the resources stored therein and the seawater and lake water internally contained in the accumulated storage of the bellows tube and floating on the seawater or lake water, and the resource captured It comprises the sixth step of transferring the circular resource recovery pipe to the transfer site.
