Description

  The present invention relates to a shading cover for a housing that protects the housing fixed through a fixing bracket from solar radiation.

  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 fixed to 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 rise is suppressed by thermal barrier coating, it does not block solar radiation. Therefore, if the solar radiation is strong, the suppression effect of the temperature increase by thermal barrier coating may be insufficient. In addition, when a metal shielding plate is attached, it is necessary to prevent radio waves from being blocked, and thus the entire casing cannot be covered. And since the attachment method of the housing to a utility pole or a suspension line is not uniform, it is necessary to prepare a plurality of types of shielding plates according to the attachment method and the attachment position.

  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.

  However, the technique described in Patent Document 1 is intended for a gas meter, and can be mounted on the ground. Moreover, since the upper side of the meter main body and the upper side of the gas stopper are covered with the gutter plate, the solar radiation from the front side or the side surface cannot be blocked.

  On the other hand, for example, a housing fixed to a utility pole or a suspension line via a fixing bracket such as a smart meter aggregation device requires work at a high place for attachment, and therefore, a housing that can be easily attached is desired. It was. Moreover, since the housing is fixed via a fixing bracket, it is necessary to block solar radiation from the side surface, front surface, and back surface in addition to the top surface.

  Accordingly, an object of the present invention is to provide a light shielding cover for a housing that can be easily attached to a housing fixed to a utility pole or a hanging line via a fixing bracket and shields solar radiation.

  In order to achieve the above object, the invention according to claim 1 is a light shielding cover for a housing that protects the housing fixed through a fixing metal from light, and the housing and the housing are fixed to each other. A sheet that is capable of covering the outer periphery of the fixing bracket, is deformable, and is disposed on one surface of the sheet, and has a convex spacer with respect to the one surface of the sheet. When the sheet is formed in a cylindrical shape so that one surface portion is on the inner side and the outer periphery of the casing and the fixing bracket is covered, the spacer contacts the casing and the fixing bracket, and the sheet and the casing or It is a light shielding cover for a housing, characterized in that a space is formed between the fixing metal fittings.

  According to this invention, when the sheet is formed in a cylindrical shape so that one surface portion of the sheet is on the inner side and covers the outer periphery of the casing and the fixing bracket, the convex spacer contacts the casing and the fixing bracket, A space is formed between the housing and the fixture.

  The invention according to claim 2 is the light shielding cover for housing according to claim 1, wherein the spacer is a plurality of long bodies arranged along the axial direction when the sheet is formed into a cylindrical shape. It is characterized by that.

  According to the first aspect of the present invention, it is possible to cover the outer periphery of the casing and the fixing bracket that fixes the casing so that the one surface portion of the sheet is on the inner side. For this reason, the whole case can be covered and light-shielded. That is, since the outer periphery of the housing and the fixing bracket can be covered, it can be attached as it is to the casing fixed through the fixing bracket.

  In addition, when the sheet is formed in a cylindrical shape and covers the outer periphery of the casing and the fixing bracket, the convex spacer comes into contact with the casing and the fixing bracket, and a gap (space portion) is formed between the casing shading cover and the casing. Therefore, it can suppress that the heat | fever of the light shielding cover for enclosures which raised the temperature by the solar radiation is conducted to the enclosure.

According to the second aspect of the present invention, since the spacer is a plurality of long bodies arranged along the axial direction when the sheet is formed into a cylindrical shape, the spacer is provided between the housing light shielding cover and the housing. In addition, since the gaps (space portions) are evenly formed along the axial direction, it is possible to more reliably suppress the heat of the housing light-shielding cover whose temperature has risen due to solar radiation to the housing.
According to the third aspect of the present invention, when the sheet is formed in a cylindrical shape, the contracted portion disposed on the outer edge portion of the sheet contracts by pulling the linear body, and the formed opening is reduced. Therefore, the outer periphery of the housing and the fixing bracket can be covered more reliably. Further, since the opening is reduced and becomes smaller than the outer periphery of the housing, the housing light shielding cover is prevented from being displaced.

Further, the drop-off preventing means 9 having the same function is disposed in the contraction portion 23.

  Next, the attachment procedure and operation of the shading cover 1 for a housing will be described. Here, as shown in FIG. 5, the case where it uses for the aggregation apparatus C1 arrange | positioned at the utility pole P via the arm bracket A1 is demonstrated.

  First, as shown in FIG. 1, the casing light shielding cover 1 in an open state is brought close to the lower side of the aggregation device C1.

  Then, the housing light-shielding cover 1 is brought close to the position where the spacer 3 comes into contact with the aggregation device C1, and one surface portion of the sheet main body portion 21 (the surface portion on which the spacer 3 is disposed) is set to the inside. 4 and 5, the sheet main body 21 is formed in a cylindrical shape so as to cover the outer periphery of the aggregation device C1 and the arm metal A1 that fixes the aggregation device C1. At this time, the short side portion 21c side of the winding portion and the overlapping portion 21A are overlapped, the overlapping portion 21A is inserted through the insertion hole 21B, and the hook surface 61 and the loop surface 62 overlap, whereby the sheet 2 is overlapped. Temporarily fixed. At this time, the gripping hole 21C of the overlapping portion 21A inserted through the insertion hole 21B is gripped by the operator, and the overlapping portion 21A is pulled.

  Then, the belt 71 is inserted through the belt loops 73 and 74, the belt 72 is inserted through the belt loops 75 and 76, and the seat 2 is locked.

And the holding part 4a of the tension | pulling cord 4 is pulled, the outer edge part side of the shrinkage | contraction part 22 is shrink | contracted, and it hold | maintains by the stopper 4b in the state which reduced opening. Similarly, the grip portion 5a of the tension cord 5 is pulled, the outer edge portion side of the contraction portion 23 is contracted, and the opening is contracted and held by the stopper 5b.
Accordingly, when the sheet body 21 is formed in a cylindrical shape and covers the outer periphery of the aggregation device C1 and the arm metal A1, the spacer 3 comes into contact with the aggregation device C1 and the arm metal A1, and the shading cover cover 1 for the casing and the aggregation device C1 A gap (space) is formed between the two. Further, by pulling the tension strings 4 and 5, the opening is reduced, and the outer periphery of the aggregation device C1 and the arm metal A1 can be covered more reliably. Further, since the opening is reduced and becomes smaller than the outer periphery of the concentrating device C1, it is possible to prevent the casing light shielding cover 1 from being displaced.

  In this way, the housing light-shielding cover 1 is attached to the aggregation device C1 disposed on the utility pole P via the arm metal A1.

  When the attached housing shading cover 1 is temporarily removed for inspection of the concentrating device C1, the tension cords 4 and 5 are loosened, the locking by the lock belt 7 is released, and the temporary fastener 6 is temporarily installed. The stop is released and the sheet main body portion 21 is opened, and the sheet main body portion 21 is moved below the aggregation device C1. At this time, the light shielding cover 1 for the casing is fixed to the hanging line by the drop-off preventing strings 8 and 9.

  And inspection work etc. of aggregation device C1 from which shading cover 1 for cases was removed are performed. After the inspection work is completed, the housing light-shielding cover 1 is attached again.

  As described above, according to the casing light-shielding cover 1, the sheet main body portion 21 is formed in a cylindrical shape so that one surface portion of the sheet main body portion 21 is on the inner side, and the outer periphery of the aggregation device C1 and the arm metal A1 is provided. Can be covered. For this reason, the aggregation apparatus C1 can be covered and light-shielded. Since the outer periphery of the concentrating device C1 and the arm metal A1 can be covered, it can be directly attached to the consolidating device C1 fixed via the arm metal A1. That is, the light shielding cover 1 for the casing can be attached as it is without removing the concentrating device C1 suspended through the arm metal A1.

  Further, when the sheet main body portion 21 is formed in a cylindrical shape and covers the outer periphery of the aggregation device C1 and the arm metal A1, the spacer 3 comes into contact with the aggregation device C1 and the arm metal A1, and between the sheet main body portion 21 and the aggregation device C1. Since a gap (space part) is formed in the sheet, it is possible to prevent the heat of the sheet main body part 21 whose temperature has been increased by solar radiation from being conducted to the aggregation device C1.

  Further, since the spacer 3 is a plurality of elliptical cylinders arranged along the axial direction when the sheet main body 21 is cylindrical, the spacer 3 is axially disposed between the sheet main body 21 and the aggregation device C1. Since the gaps (space portions) are evenly formed along the surface, it is possible to more reliably suppress the heat of the sheet main body portion 21 whose temperature has risen due to solar radiation to the aggregation device C1.

  Further, when the sheet main body 21 is formed in a cylindrical shape, by pulling the tension strings 4 and 5, the outer edge portions of the contracting portions 22 and 23 are contracted, and the formed opening is contracted. The outer periphery of the arm metal A1 can be covered more reliably. Further, since the opening is reduced and becomes smaller than the outer periphery of the concentrating device C1, it is possible to prevent the casing light shielding cover 1 from being displaced.

  And since the sheet | seat 2 is comprised with the heat insulation raw material, the temperature rise of the light shielding cover 1 for housings itself can be suppressed, and the heat insulation effect by the light shielding cover 1 for housings can be improved more.

  The housing light-shielding cover 1 is detachable, and since the longitudinal end face side of the housing light-shielding cover 1 is open, it does not interfere with the cable E, and is therefore an aggregating device that is fixed via the brace A1. Without removing C1, the shading cover 1 for the chassis can be retrofitted.

  Since it is the sheet | seat 2, the radio wave permeability of the communication apparatus of the aggregation apparatus C1 accommodated in the inside does not fall. Moreover, since the light-shielding cover 1 for a casing is reduced in weight, handling in a high place work becomes easy.

  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, as shown in FIG. 5, the case where it is used for the aggregation device C1 disposed on the utility pole P via the arm metal A1 has been described, but the present invention is not limited to this place. Of course, it is possible to attach the aggregation device C which is fixed by another method such as the aggregation device C suspended from the suspension line. Specifically, as shown in FIGS. 6 and 7, the shading cover 1 for the casing is similarly attached to the aggregation device even when the arm metal A <b> 2 is disposed on the side surface of the aggregation device C <b> 2. It can be attached so as to cover the outer periphery of C2 and arm metal A2.

  Moreover, although the short side part 21c side of the winding part and the overlapping part 21A were overlapped and described as inserting the overlapping part 21A through the insertion hole 21B, the insertion hole 21B may not be provided. In this case, the short side portion 21c side of the winding portion and the overlapping portion 21A are overlapped, the hook surface 61 and the loop surface 62 are overlapped, the sheet 2 is temporarily fixed, and the belt 71 is belt-passed 73, 74, and the belt 72 may be inserted into the belt loops 75 and 76 to lock the seat 2.

  Further, the sheet fastener 21 is described as being temporarily fixed by the surface fastener 6 as the temporary fixing means, but the surface fastener 6 may be omitted. In this case, the short side portion 21c side of the winding portion and the overlapping portion 21A are overlapped, the overlapping portion 21A is inserted through the insertion hole 21B, the belt 71 is inserted through the belt loops 73 and 74, The belt 72 may be inserted into the belt loops 75 and 76 to lock the seat 2.

  Furthermore, the shape of the spacer 3 is not limited, and may be another shape as long as a gap (space portion) is formed between the sheet main body 21 and the aggregation device C1.
