Description

  The present invention relates to a light shielding cover for a suspended housing that protects a housing suspended from a fixing bracket from sunlight.

  For example, a smart meter aggregation device has a function of collecting meter reading data from smart meters installed in each home, and a communication device and a power supply device for transmitting the data to a data center on the power company side are in the housing. Are housed in Since this smart meter aggregation device is suspended from a utility pole or suspension line via a fixing bracket, it is directly irradiated with sunlight and becomes extremely hot especially in summer. When the smart meter aggregation device becomes hot, there is a risk that the communication equipment, power supply device, etc. in the housing may break down, and thus the temperature rise is suppressed by applying a thermal barrier coating to the outer surface of the housing.

  However, even if the temperature increase is suppressed by the thermal barrier coating, the solar radiation is not blocked. Therefore, when the solar radiation is strong, there is a possibility that the suppression effect of the temperature increase only by the thermal barrier coating is insufficient.

  For a gas meter installed outdoors, a technology related to a protective structure for gas piping equipment that protects from direct sunlight or the like is known (see Patent Document 1). In this technology, a gutter plate that covers the entire area of the meter body including the gas inlet portion and the gas outlet portion and the upper portion of the gas plug is provided over the entire area. It is attached to a support that can be fixed.

  Next, the attachment procedure and operation of the light shielding cover 1 for the suspension type housing will be described.

  First, as shown in FIG. 5, the lock means 4 and 5 are unlocked, and the slide portions 61 and 71 are slid to move the upper peripheral edge portion 2 a of the first cover 2 and the upper peripheral edge portion of the second cover 3. 3a is moved in the direction of separating and opened, and positioned below the aggregation device 110.

  Then, as shown in FIG. 6, the suspended casing shading cover 1 is lifted upward, and the upper peripheral edge 2 a of the first cover 2 and the upper peripheral edge 3 a of the second cover 3 in the opened state The concentrator 110 is accommodated in the interior of the suspension type shading cover 1, that is, in the space portion S.

  Then, the slide portions 61 and 71 are slid so that the upper peripheral edge portion 2a of the first cover 2 and the upper peripheral edge portion 3a of the second cover 3 are brought close to each other. At this time, a rectangular opening is formed by the notches 23A and 33A and 23B and 33B at positions corresponding to the fixing bracket 111 of the aggregation device 110.

  Then, as shown in FIG. 2, the bands 41 and 51 of the locking means 4 and 5 and the fasteners 42 and 52 are locked, so that the upper peripheral edge 2 a of the first cover 2 and the second cover 3 The upper peripheral edge portion 3a is fixed in close contact. Further, the fixing bracket 111 is surrounded by a rectangular opening formed by the notches 23A and 33A and 23B and 33B. In this way, the suspension type shading cover 1 is attached to the aggregation device 110 that is suspended from the suspension line 100 via the fixing bracket 111.

  When temporarily removing the attached suspension type shading cover 1 for inspection of the aggregation device 110, the lock means 4 and 5 are unlocked, and the slide portions 61 and 71 are slid, The first cover 2 is moved downward in the aggregation device 110 in a state where the upper peripheral edge 2a of the first cover 2 and the upper peripheral edge 3a of the second cover 3 are swung in the direction of separating and opened. At this time, the suspension type shading cover 1 is fixed to the suspension line 100 by the drop-off prevention means 8 and 9.

  As described above, according to the suspension type casing light shielding cover 1, the first cover 2 and the second cover 3 are larger than the width of the aggregation device 110 in a state where the first cover 2 and the second cover 3 are swung open. Since it opens, it can attach as it is, without removing the aggregation apparatus 110 suspended via the fixing metal fitting 111. FIG. At this time, anyone can easily attach to the correct position by the lock means 4 and 5 and the slide means 6 and 7.

Since the opening of the shape is formed, it can be attached as it is to the aggregation device 110 suspended through the fixing bracket 111. At this time, since the fixing bracket 111 is surrounded by the rectangular opening, it is possible to prevent the suspension type casing light shielding cover 1 from being displaced with respect to the aggregation device 110.

  Further, since the eaves portions 21 and 31 are formed, the aggregation device 110 can be reliably shielded from light even when the sun is located at a position other than directly above.

  Further, when the upper peripheral edge 2a of the first cover 2 and the upper peripheral edge 3a of the second cover 3 are in close contact, the lower peripheral edge 2b of the first cover 2 and the lower peripheral edge of the second cover Since 3b is opened away, heat can be prevented from being generated in the space S between the suspension type shading cover 1 and the concentrating device 110.

  Furthermore, since the 1st cover 2 and the 2nd cover 3 are the heat insulation structures which have cavity 2S, 3S inside, the heat insulation effect by the light shielding cover 1 for suspension type enclosures can be improved more. Moreover, since the 1st cover 2 and the 2nd cover 3 have the cavities 2S and 3S inside, the light-shielding cover 1 for suspension type enclosures is reduced in weight.

  The embodiment of the present invention has been described in detail above, but the specific configuration is not limited to the above-described embodiment, and even if there is a design change or the like without departing from the gist of the present invention, It is included in this invention. For example, in this embodiment, although the case where it uses for the aggregation apparatus 110 suspended by the suspension line 100 was demonstrated, even if it is not restricted to this place and is suspended by the utility pole, Of course, it can be attached by adjusting the size, shape and arrangement position of the notch.
