Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a support base flow path device that rotatably supports a house, an observation room, or the like around a vertical axis.

(Conventional technology) As a conventional technology, a fixed base is placed at the center of rotation,
A donut-shaped rotating base that rotates around the vertical axis is placed on the outer periphery of the fixed base, and a flow path device for circulating tap water, gas, waste water, etc. is provided on the fixed base side, and these are connected to the fixed base side. Some were designed to connect to the flow pipes of the installed cooking rooms, toilets, etc.

(Problems to be Solved by the Invention) The above-mentioned conventional device has a structure in which the one-rotation base is placed on the outer periphery of the fixed base and rotates around the fixed base, so water pipes, gas pipes, It was difficult to install a cooking room or toilet that required a drainage pipe, and the types of equipment that could be installed on the rotating base side were limited.

Furthermore, there are objects that move relative to each other on the same plane, resulting in poor safety.

An object of the present invention is to obtain a novel flow path device that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to solve the above-mentioned drawbacks, the present invention is constructed as follows.

That is, a rotating base that can rotate about a vertical axis is placed above a fixed base installed on the ground, and a fixed cylinder that is supported upright on the fixed base and suspended from the rotating base are placed at the axial center of the rotating base. The supported rotary cylinder is fitted so as to be able to rotate relative to each other.

A drainage channel is communicated with the axial center of the fixed tube and the rotating tube, and a plurality of annular channels are provided in the vertical direction that continue in the circumferential direction at the fitting part of the fixed tube and the rotating tube, and each annular channel is provided with a drainage channel. A fixed flow path opens from the annular flow path to the outside through the inside of the wall of the fixed cylinder, and a rotating flow path opens to the outside through the inside of the wall of the rotary cylinder.

(Function) Since the present invention is configured as described above, the fixed base is located below the rotating base, and no non-rotating member exists at the axial center of the rotating base.

In addition, each of the fixed channels that open to the outside from the fixed cylinder side and each of the rotating channels that open to the outside from the rotating cylinder side are each connected to each other by each annular flow path formed at the fitting portion of the fixed cylinder and the rotating cylinder. They communicate independently and relatively rotatably with each other.

Therefore, each flow pipe on the ground side and each flow pipe on the rotating base side are smoothly connected via each of the fixed flow channels and each rotating flow channel.
