Description

  The present invention relates to a power supply box that houses electrical equipment and is installed outdoors, and particularly relates to a lining structure of a box that is assembled with bolts, nuts, etc. regardless of a welded structure.

  Conventionally, regarding the frame of a box such as a power box that houses electrical equipment and is installed outdoors, the components of the box such as the base, outer wall, and roof are first made into an integral structure by welding, and then rust-proof. For this purpose, this monolithic structure was dipped in hot dip galvanizing.

  However, the frame of the box as described above may cause thermal strain. Therefore, there is a problem in that the door may not be successfully attached to the frame in the subsequent door attachment process.

  Therefore, the frame of the box is composed of several parts, after which these parts are galvanized, and then the galvanized parts are joined together with bolts and nuts to assemble the box frame. In this way, a box that does not cause thermal distortion and has no problems such as vent holes is assembled.

The box as described above is described in the following patent documents and is publicly known.
JP 2001-339815 A

  In addition, a power supply device is arranged inside a box such as a power supply box, but the power supply device is often equipped with electronic components that are damaged due to temperature changes. In such a case, it is required that the room temperature of the power supply box be maintained at +5 to + 40 ° C. with respect to the outside air temperature range of −35 to + 35 ° C. For this reason, a heat insulating material is stretched inside the outer wall to insulate, and the heater and the ventilation port are controlled in accordance with changes in the room temperature to keep the room temperature within a predetermined temperature range.

  Furthermore, the heat insulating material is made of a soft material such as polystyrene foam, and the surface of the heat insulating material on the inside of the box is exposed when it is damaged during equipment installation or maintenance inspection. Therefore, the surface of the heat insulating material inside the box is covered with a lining material made of a thin steel plate.

  As mentioned above, the frame of the box is composed of several parts. After that, these parts are galvanized, and then the galvanized parts are connected with bolts and nuts to assemble the frame of the box. Although it can be set as a box without thermal distortion, there are the following problems when arranging the heat insulating material inside the outer wall and the lining material inside the heat insulating material.

  That is, conventionally, a heat insulating material is disposed on a base that is a framework of a box, and a lining material is attached to the upper surface of the heat insulating material, and the lining material is used as a floor board. In order to fix the (floor board) to the foundation, it was necessary to use a large number of bolts or the like.

  Further, the heat insulating material is arranged inside the outer wall which is the frame of the box and a lining material is attached to the surface inside the box of the heat insulating material, and this lining material is used as the inner wall. In order to fix the lining material (inner wall) to the outer wall, it is necessary to use a large number of bolts and the like.

  Furthermore, the heat insulating material is arranged inside the roof, which is the frame of the box, and a lining material is attached to the surface inside the box of the heat insulating material, and this lining material is used as a top plate. In order to fix the lining material (top plate) to the roof, it is necessary to use a large number of bolts and the like.

  In this way, conventionally, when assembling the outer member and inner member of the box, a construction method based on the existing concept of general buildings is adopted, so many parts are connected using bolts, nuts, etc. I had to match. Therefore, many bolts and nuts are used, which requires a lot of work. Moreover, since it takes time to assemble, there is a problem that the cost increases.

  An object of the present invention is to solve the problems of the above-described conventional box. In other words, the existing construction method is reviewed to reduce the number of bolts and the like, and to provide a lining structure for the power supply box that does not require labor for assembly.
