Description

The present invention relates to a mounting structure of a measuring device.

As an example of a seismograph installed in a building such as a detached house, the one described in Patent Document 1 is known. This seismograph includes an acceleration sensor that detects the acceleration caused by the shaking of an earthquake, and a case in which the acceleration sensor is housed.

Japanese Patent No. 5660822

By the way, in recent years, it has been promoted to install seismographs not only in detached houses but also in various facilities formed larger than detached houses such as schools, hospitals, government buildings and the like. Such various facilities have various cases such as having an underground floor or not being able to enter an underground pit, and it is conceivable to install a seismograph in a place different from the foundation such as a detached house.
However, in the case of such various facilities, unlike a detached house, the facility manager may go under the floor of the basement floor or the lowest floor to perform the work. In addition, if there is a parking lot or a store on the basement floor, people other than the facility manager may come and go, and it is possible that unnecessary contact between the installed seismograph and people or things will occur. If it comes into contact with the seismograph, the acceleration sensor inside the case will detect the vibration, so accurate measurement may not be possible.

A power cable 6a for receiving power supply from the power supply unit 6 (shared power supply: AC100V power supply) is connected to the device main body 11. The power cable 6a is wired between the power supply unit 6 and the measuring device 10 through a through hole formed in the case 12.
The power cable 6a is covered with a cable cover 6b outside the case 12 to prevent the power cable 6a from coming into contact with people or objects. Further, the wiring distance of the power cable 6a extending from the device main body 11 is 30 m or less.

The case 12 has a case mounting portion 13 which is a mounting portion for the structures 4 and 5, a wall portion 14 which protrudes from the case mounting portion 13 and surrounds the periphery of the device main body 11, and a lid which is detachably provided on the wall portion 14. It has a part 15.

The case mounting portion 13 is formed in a flat plate frame shape, and has an opening 13a set in a range wider than the contact area of the structure 4 and 5 in the apparatus main body 11 in the center. That is, the device main body 11 is attached to the structures 4 and 5 so as to fit inside the inner edge of the opening 13a in the case attachment portion 13.

There is a site 14a where is formed. Further, a lid mounting portion 14b having a hole into which a fixture 7 such as a screw can be screwed is integrally formed in the inside corner portion formed by the plurality of wall bodies.

The lid portion 15 is provided on the end surface of the wall portion 14 on the rising direction side, and a through hole is formed in a corner portion of the lid portion 15 corresponding to the position of the lid mounting portion 14b. That is, the lid portion 15 is fixed by passing a fixing tool 7 such as a screw through a through hole formed in a corner portion and screwing the fixing tool 7 into a hole of a lid mounting portion 14b in a wall portion.

The wall portion 14 in the present embodiment is assumed to have wall bodies provided on all sides to form four corners, but the present invention is not limited to this, and may be circular. Although not shown, in the case of a circular wall portion, the lid portion is also circular, and a through hole in the lid portion through which the lid mounting portion and the fixture 7 are passed is appropriately provided.
Further, although the wall portion 14 is formed by the wall body rising from the outer edge of the case mounting portion 13, it may be formed by the wall body rising from the inner edge of the case mounting portion 13.

It will be placed in the position where it was.
In short, when the device main body 11 and the case 12 are mounted on the same surface of the wall structure 4, they are separated from the device main body 11 so that the edge of the opening 13a in the case mounting portion 13 does not come into contact with the device main body 11. It is attached.

The device main body 11 is arranged so that one side surface facing the wall structure 4 is in contact with the surface of the wall structure 4, and the device mounting portion 11b provided on the one side surface 11a side is connected to the wall structure 4. A fixture 7 such as a screw is screwed into the attachment.
The case 12 is arranged so that the case mounting portion 13 is in contact with the surface of the wall structure 4 without the lid portion 15 with respect to the wall structure 4, and the case 12 is screwed from the case mounting portion 13 toward the wall structure 4. Etc. 7 is screwed into the fixture. The lid portion 15 is then fixed to the wall portion 14.
