Description

  The present invention relates to an electric equipment storage box.

  As described in Patent Document 1, an electric equipment storage box having a roof is known. In many cases, the lower end portion of the roof of the electrical equipment storage box having such a configuration is provided with a bent portion bent toward the door side.

JP 2010-81730 A

  By the way, when rainwater flows down through the roof, it does not fall down from the end of the roof but flows down through a bent portion provided at the lower end of the roof. For this reason, if the door is opened in the rain, the rainwater may flow down inside the box and wet the equipment arranged inside the box.

  The inventor of the present case tried to solve the problem by diligently examining this point. An object of the present invention is to prevent rainwater that flows down the roof of an electrical equipment storage box from entering the electrical equipment storage box.

  In order to solve the above-mentioned problems, an electrical equipment storage box having a roof, comprising a rain return portion projecting to the outside of the roof, and for storing electrical equipment in which the angle between the rain return portion and the side of the roof is an obtuse angle A box.

  Moreover, it is preferable to set it as the structure by which the rain return member provided with the rain return part was attached to the lower surface of the roof.

  Moreover, it is preferable that the rain return member provided with the rain return portion is provided with a long hole and a notch as a portion used for attachment to the roof.

  In this invention, it becomes possible to suppress that the rain water which flows down through the roof of the electrical equipment storage box enters the electrical equipment storage box.

It is a perspective view of the electric equipment storage box of an embodiment. It is a side view of the electric equipment storage box of an embodiment. It is the elements on larger scale around the roof and rain return part of FIG. It is the figure which looked around the rain return member attached to the roof from the downward direction. It is a perspective view of a rain return member.

  The form for implementing this invention is shown below. As can be understood from FIGS. 1 to 3, the electric device storage box 1 of the present embodiment includes a roof 11. Moreover, the rain return part 21 which protrudes the outer side of the roof 11 is provided, and it is comprised so that angle (theta) which the rain return part 21 and the side surface of the roof 11 make may become an obtuse angle. For this reason, it becomes possible to suppress the rainwater flowing down through the roof 11 of the electrical equipment storage box 1 from entering the electrical equipment storage box 1.

  The electrical equipment storage box 1 of this embodiment is a cubicle type high-voltage power receiving facility used particularly outdoors, and includes a roof 11 whose upper surface is inclined. Moreover, a door is attached so that the opening divided by the rectangular frame member arrange | positioned at each front and back may be covered. Beams extending in the front-rear direction are connected so as to connect the respective rectangular frame members, and a skeleton is formed by the beams and the frame members.

  The rain return portion 21 provided on the roof 11 of the embodiment protrudes from the side surface of the roof 11 on the side where the door 12 is located, and rainwater transmitted from the side surface of the roof 11 can be moved further outward. . More specifically, the angle θ formed by the side surface of the roof 11 and the rain return part 21 is configured to be an obtuse angle, and rainwater that has flowed down through the rain return part 21 is prevented from flowing to the door 12 side. Can do. In addition, it is preferable to form the position which provides the rain return part 21 so that it may protrude from the lower side edge part of the side surface of the roof 11. FIG.

  If the rain return portion 21 is formed of a member different from the roof 11, the rain return portion 21 can be retrofitted to the roof 11 of the existing electrical equipment storage box 1 to prevent rainwater from entering the box. Can do. For example, as can be understood from FIG. 3 or FIG. 4, the rain return member 2 including the rain return portion 21 may be attached to the lower surface of the roof 11. In this way, rainwater is less likely to accumulate in the fixing portion where the stopper metal or the like is inserted than when the rain return member 2 is fixed to the side surface of the roof 11. Moreover, since rainwater does not easily accumulate in the fixed portion, the occurrence of rust is also suppressed.

  By the way, a lifting eye bolt 91 is fixed to the upper surface of the roof 11 having a substantially U-shaped cross section. A vent hole plate 13 is provided inside the surface provided at the lower portion of the roof 11, and is fixed to the surface provided at the lower portion of the roof 11 using bolts 93. Therefore, in the embodiment, the rain return member 2 including the rain return portion 21 is fixed to the roof 11 by fastening with the ventilation hole plate 13 using the bolt 93 to which the ventilation hole plate 13 is fixed. ing. In this way, the number of parts can be reduced, and there is no need to drill holes in the electrical equipment storage box 1. The ventilation hole plate 13 is provided with a plurality of ventilation holes 14 to prevent intrusion of foreign matters while allowing ventilation.

  As can be understood from FIG. 5, the rain return member 2 of the present embodiment is provided with two attachment holes, one of which is a long hole 23 and the other is a notch 25. Yes. If the notch 25 is provided for use in the attachment to the roof 11, the bolt 93 that fixes the vent hole plate 13 is loosened so that the bolt 93 is positioned in the notch 25. The rain return member 2 can be temporarily fixed by moving the rain return member 2. If it will be in this state, since it becomes easy to insert the volt | bolt 93 in the long hole 23 after that, the workability | operativity of attachment can be improved.

  Further, if the long hole 23 is provided for use in the attachment to the roof 11, the bolt 93 is loosened due to vibration of the internal equipment after fixing the rain return member 2. However, since the rain return member 2 is held in the vicinity of the portion of the long hole 23 until the bolt 93 is removed, the rain return member 2 is difficult to fall off. That is, if both the long hole 23 and the notch 25 are provided as attachment holes used for attachment to the roof 11, it is possible to improve the attachment workability and to prevent the rain return member 2 from dropping off. it can.

  The rain return portion 21 of the present embodiment is provided so as to protrude obliquely downward from the side surface of the roof 11 on the side where the door 12 is located. In addition, the side surface of the roof 11 of the embodiment is provided so as to extend in a substantially vertical direction, and the lower surface of the roof 11 is provided so as to extend in a substantially horizontal direction. In the embodiment, the rain return part 21 is provided by attaching the rain return member 2 to the lower surface of the roof 11, but this rain return part 21 is provided by bending the flat plate once in an obtuse angle. The lower end portion is provided so as to extend obliquely downward. For this reason, the rain return part 21 can discharge | release the rainwater which flowed down vigorously from the upper part toward the diagonally downward direction from the lower end in the direction which slipped down. That is, rainwater can be discharged away from the electrical device storage box 1. In addition, the rain return member 2 configured in such a form that two planes are connected to each other is provided with a long hole 23 and a notch 25 on the surface that is not the rain return portion 21.

  As mentioned above, although it demonstrated centering on one embodiment, this invention is not limited to the said embodiment, It can be set as various aspects. For example, the rain return part is not limited to being a separate member from the roof, and may be formed integrally with the roof.

  The number of mounting holes is not two, but may be three or more. In addition, when there are three or more attachment holes, the attachment holes can be easily attached if the number of the attachment holes is larger than that of the long hole shape.

  The rain return portion does not need to protrude outward from the lower end of the side surface of the roof, and may be configured to protrude outward from a position between the upper end and the lower end of the side surface of the roof.
