Description

[Detailed Description of the Invention] This invention relates to a waveguide connection structure when installed for radio wave transmission between devices in a radar system, for example.

Conventionally, as shown in Fig. 1, the waveguides of a radar system are connected by a waveguide 3, a flexible waveguide 4, and a waveguide 5 between devices 1 and 2 installed at different locations. The wave tube 3 and the waveguide 5 were fixed by a waveguide support 9 and a waveguide support 10.

However, a number of earthquake countermeasures are now being implemented in various areas. For example, the floors of important equipment are equipped with vibration dampers to prevent damage caused by earthquakes. In this case, the seismic isolation effect is enhanced by sufficiently moving the movable floor above the fixed floor of the vibration absorbing damper. If a waveguide having a conventional structure is connected to such a device, the amount of displacement of the flexible waveguide 4 alone cannot cope with the amount of displacement, resulting in damage to the waveguide.

The purpose of this invention was to make it possible for the waveguides connecting the devices to follow the movement of the devices even if the devices installed at different locations oscillated greatly, so that the connecting waveguides would not be damaged. An object of the present invention is to provide a waveguide connection structure.

This invention provides at least a first waveguide, a first flexible waveguide, and a second waveguide between two devices installed on two floors, one of which is swingable relative to the other. A waveguide in which a pipe, a second flexible waveguide, and a third waveguide are connected in series, and the lower part of the second waveguide is fixed to one of the floors so as to be swingable in the horizontal direction. This is a waveguide connection structure characterized by being fixed to a tube slide.

Next, an embodiment of this invention will be described with reference to the drawings.

As shown in FIG. 2, at least a waveguide 3, a flexible waveguide 4, a waveguide 5, a flexible waveguide 6, and a Connect wave tube 7 in series,
A waveguide slide 8 is attached to the lower part of the waveguide 5,
The waveguide 3 and the waveguide 7 are placed on the respective floor surfaces 11 and 12.
The waveguide support 9 and the waveguide support 10 are used to fix the waveguide support 9 and the waveguide support 10 . The flexible waveguide 4 and the flexible waveguide 6 follow the movement of the floor of the device 1 or 2. The waveguide slide 8 supports the weight of each waveguide and provides no restriction to the horizontal movement of the flexible waveguide 4 and the flexible waveguide 6.

In this waveguide connection structure, even if the device 1 or 2 moves differently due to an earthquake, the flexible waveguide 4 and the flexible waveguide 6 will move according to the movement, and the waveguide slide 8 will be connected to the waveguide. It supports the weight of the flexible waveguide 4 and the flexible waveguide 6, and prevents damage to the waveguide.

According to this invention, as explained above, by connecting the waveguides, it is possible to prevent damage to the waveguides even if the floor on which each device is installed moves differently.
