2. Description of the Related Art As a vertical transport method, there are an elevator system driven by a motor or an engine powered by commercially available energy such as electric power or oil, a wire direct suspension system,
A device using a vertical transfer device such as a rack rail system is known.

The above-mentioned conventional vertical transport apparatus requires a large-capacity transport at a high lift and requires a long period of time as in the construction of a deep underground structure, and the following construction is required. There's a problem. 1. All conventional vertical transfer devices use commercially available energy, and the energy cost is enormous. 2. In the elevator method or the wire direct suspension method using a wire for a high head, the transport capacity is limited because the wire diameter becomes large and the weight of the wire and related parts increases. At a depth of several hundreds of US, there is a mechanical problem. 3. Although the rack rail system has a transport device equivalent to a human load elevator, it is not suitable for high-lift large-volume transport due to problems in rail strength and transport gauge mechanisms. 4.
Since it takes a long time underground to construct, it requires enormous maintenance work and cost, such as corrosion prevention of the transfer equipment and countermeasures against electric leakage, which is not economical. In order to solve the above-mentioned problem, the present invention secures a rising force by buoyancy of water or muddy water as energy of vertical conveyance, and controls a falling speed by buoyancy by air resistance, thereby enabling high-lift mass conveyance by natural energy. The purpose is to do.

And a loading door at the entrance of the loading pit, and a hydraulic pressure control valve between the lower part of the shaft and the loading pit to open and close the shielding door and the loading door in a predetermined order. Then, the transfer capsule was extruded to the lower part of the shaft, so that the transfer capsule was floated in the shaft by the buoyancy of the liquid. To lift a long shaft at a given speed,
The inside of the shaft is divided into several sections vertically by a plurality of partition doors, and the transport capsules are floated for each section by opening the partition doors sequentially from the bottom.

It is not necessary to use commercially available energy if the articles are transported in the transport capsule. In addition, by lifting the heavy load by the buoyancy of the liquid and controlling the falling speed of the transport capsule from which the load has been taken out, the transport capsule is circulated up and down between underground and ground.
