Description

  The present invention relates to a substructure of an outdoor installation device, and more particularly, to a bottom surface portion that is easily soiled by deposits on the surface of the device and having the same durability as other wall surface portions.

  Conventionally, various devices have been installed in outdoor utility poles, for example, transformers that connect power lines from power plants and convert them to low voltages that can be used in homes, etc., and low voltage from those transformers A balancer is installed to correct the load imbalance by connecting the wires.

  In outdoor installation equipment such as transformers and balancers, insulating oil is contained in a metal container to ensure insulation, and the outer surface of this container is coated with paint to prevent corrosion. Yes.

  However, in such outdoor installation devices such as conventional transformers and balancers, the inner housing material is designed not to leak due to damage to the bottom surface and progress of corrosion. In the balancer 100 shown in FIG. 6, the bottom surface portion 102 is designed to have a bottom-up shape, and both the front back surface portion (front surface and back surface wall surface portion) 103 and the side surface portion (side surface wall surface portion) 104 (entire circumference). The support portion 105 is constituted by a member formed by extending (extending) the.

  If the bottom-up support portion 105 is formed on the periphery of the bottom surface portion 102, for example, in the case where the support portion 105 is installed on the coastal portion, splashes of seawater containing salt are present on the front back surface portion 103 and the side surface portion 104. Even if it adheres, it will be washed away with rainwater or the like and will not cause a big problem, but rainwater cannot enter the bottom surface portion 102 due to the support portion 105 at the periphery thereof. For this reason, in this balancer 100, there exists a possibility that the insulation oil (accommodating material) accommodated at an early stage may leak because corrosion is accelerated by the salt contained in the attached seawater. For this reason, outdoor installation equipment such as a transformer and a balancer has a problem in that it requires frequent repainting and replacement, and costs increase.

  Here, it has been proposed to provide a photocatalytic function to the exterior of the outdoor installation equipment so that it can be kept clean without trouble (see, for example, Patent Documents 1 and 2), such as a transformer or a balancer. Thus, it is conceivable to provide a photocatalytic function so that the insulating oil to be stored does not leak to the outside.

However, if the support portion 105 for raising the bottom is formed on the periphery of the bottom surface portion 102, the deposits decomposed by the photocatalytic function cannot be washed away with rainwater, and the effect of the photocatalytic function is sufficiently obtained. There is a problem that cannot be obtained.

  Therefore, the present invention avoids the leakage of the material accommodated inside by causing rainwater or the like to circulate from the wall surface portion to the bottom surface portion and corroding the bottom surface portion significantly earlier than the wall surface portion. An object of the present invention is to provide a substructure of outdoor equipment that can extend the maintenance period.

  The first invention of the lower structure of an outdoor installation device that solves the above-described problem is that the bottom surface portion is placed on the placement surface when placed on a placement surface such as a floor surface or the ground temporarily or over a long period of time. It has a support part that supports it so that it does not come into contact, and it is the structure of the lower part of equipment installed outdoors, and does not restrict water flowing through the wall surface part of the equipment from going around the wall part to the bottom part Thus, the support portion is formed, and at least the photocatalyst material is attached to the bottom surface portion.

  In this invention, the substance adhering to the bottom surface part can be decomposed by the photocatalytic function, and the water flowing through the wall surface of the device is not restricted by the support part, for example, the photocatalyst material adheres from between the support parts. It is possible to easily wash away the decomposed substances that go around the bottom portion and adhere to the bottom portion. Therefore, the function of decomposing the adhering substance by the photocatalyst on the bottom surface portion can be used effectively, and the bottom surface portion can also be saved in a clean state that is almost equivalent to the wall surface portion.

  In addition to the specific matter of the first invention, the second invention of the lower structure of the outdoor installation device that solves the above problem is that the bottom surface portion is formed on an inclined surface that is inclined from one to the other. It is a feature.

  In the present invention, rainwater or the like flowing on the wall surface of the device flows from the upper part to the lower part on the surface of the inclined bottom part. Therefore, since the bottom surface portion is horizontal, rainwater cannot be efficiently flowed over the entire surface, and unevenness in cleaning the bottom surface portion can be prevented, and the attachment remaining on the bottom surface portion can be prevented. It is possible to effectively avoid corrosion due to the kimono.

  In addition to the specific matter of the first invention, the third invention of the lower structure of the outdoor equipment that solves the above problems is formed on an inclined surface having a bottom portion in the middle between the wall surface portions. It is characterized by being.

  In this invention, rainwater or the like flowing on the wall surface of the device flows from the upper part on both sides to the lower part in the middle on the surface of the bottom surface of the inclined surface that descends inward. Therefore, since the bottom surface portion is horizontal, it is not possible to efficiently flow rainwater over the entire surface of the surface, and it is possible to prevent unevenness in cleaning the bottom surface portion. It is possible to more effectively avoid corrosion and the like due to the deposits remaining on the bottom surface by using the rainwater flowing around the wall surface effectively.

Therefore, since the bottom portion is horizontal, it is possible to prevent rainwater from flowing efficiently over the entire surface, and to prevent unevenness in the cleaning of the bottom portion. It is possible to more effectively avoid corrosion and the like due to the deposits remaining on the bottom surface by using the rainwater flowing around the wall surface effectively.

  The fifth invention of the substructure of the outdoor equipment that solves the above-described problems is the above-mentioned specific matter of the second or third invention, wherein the wall surface portion is continuous through a substantially square shape, and the support The portion is constituted by a member obtained by extending a wall surface portion located on the side of the bottom surface portion in the inclination direction.

  In this invention, the support part produced by extending the wall part formed in the outer shape such as a prismatic shape downward is formed by extending only a part of the wall part, thereby forming the part without the support part. Thus, the bottom surface can be made continuous from the wall surface. Therefore, the support part which does not restrict | limit rain water etc. from a wall surface part to a bottom face part can be produced simply and easily.

  According to a sixth aspect of the lower structure of the outdoor device for solving the above-mentioned problems, in addition to the specific matter of the fourth aspect, the wall surface portion is formed in a substantially circular cross-sectional shape in the horizontal direction, and the support portion Are arranged so as to be located at a plurality of locations on the periphery of the bottom surface portion.

  In this invention, a part of the wall surface part formed in the outer shape such as a cylindrical shape is extended downward to form support parts located at a plurality of positions on the periphery of the bottom surface part, or the periphery of the bottom surface part. By separately disposing the support portion, the portion without the support portion can be formed to be a bottom surface portion continuous from the wall surface portion. Therefore, the support part which does not restrict | limit rain water etc. from a wall surface part to a bottom face part can be produced simply and easily.

  As described above, according to the present invention, the adhering substance on the bottom surface portion is decomposed by the photocatalyst, and the decomposed material on the bottom surface portion can be washed away by flowing in the water flowing through the wall surface portion of the device. The function can be used effectively, so that the bottom surface can be kept in a clean state as close as the wall surface. Therefore, it is possible to prevent the bottom surface portion from corroding significantly earlier than the wall surface portion, and it is possible to avoid leakage of the material accommodated therein. As a result, it is possible to lengthen the maintenance period such as cleaning the outdoor installation equipment, and it is possible to prevent the outdoor installation equipment from being soiled.

  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, the best embodiment of the invention will be described based on the drawings. 1 and 2 are views showing a first embodiment of a lower structure of an outdoor installation device according to the present invention.

  In FIG. 1, a balancer 10 is an outdoor installation device that is suspended from the arm 2 of the utility pole 1, and the balancer 10 is a device that converts electric power supplied from a power plant into a low voltage that can be used in each household. By connecting to the illustrated transformer via the low voltage electric wire 3, it is installed in order to realize a stable power supply independent of the load of each household.

  The balancer 10 contains an insulating oil that immerses the apparatus main body in a metal container 11, and this container 11 is composed of a front back surface portion (a wall surface portion on the front side and a back surface side) 13 and a side surface portion (on the side surface side). The wall surface portion 14 is formed in a substantially prismatic shape that is continuous in a substantially square shape.

  The balancer 10 is coated on the outer surface of the container 11 so that the insulating oil accommodated in the container 11 does not leak due to corrosion, and is placed on the floor or the ground during transportation / storage. In order to avoid the progress of corrosion due to the bottom surface portion 12 being in direct contact with the floor surface or the like and being damaged, the bottom surface portion 12 is formed in a raised shape like the balancer 100 shown in FIG.

  Further, the balancer 10 is designed to have a shape in which the front and rear surface portions 13 are not extended downward and are continuous with the bottom surface portion 12, while the side surface portion 14 is lowered (extended) below the bottom surface portion 12. The bottom portion 12 is inclined between the front and back portions 13, for example, from one side on the front side to the other side on the back side. That is, in the balancer 10, a support portion 15 is formed by extending a side surface portion 14 located on the side of the inclined surface of the bottom surface portion 12 formed on the inclined surface, and the front back surface portion 13 has a rectangular shape 12a, It continues to the bottom surface part 12 through 12b.

  Thereby, it is possible to support the bottom surface portion 12 so as not to contact the floor surface or the like with a shape that can be easily designed to function as the support portion 15 by extending only the side surface portion 14 downward. Further, by making the front back surface portion 13 continuous with the inclined bottom surface portion 12, the bottom surface actively (without obstructing) rainwater flowing on the surface of one of the front back surface portions 13 (here, the front side). Unnecessary materials that wrap around the surface of the portion 12 and adhere to the surface can be washed away in an inclined direction. For example, since it was installed in the coastal area, splashes of seawater containing salt remained and remained. Even so, it can be washed away with rainwater and cleaned.

  In addition, the balancer 10 is formed with a coating having a photocatalytic function of titanium dioxide on at least the entire surface of the bottom surface portion 12 and the inner surface of the support portion 15. For example, like the photocatalyst described in Document 2, the balancer 10 is made of apatite. The coated titanium dioxide powder is sprayed before the coating film applied to the outer surface of the container 11 is dried to give a photocatalytic function. Note that the material having the photocatalytic function and the operation to be applied are not limited to this, and may be a material other than titanium dioxide, and may be immersed to the extent that the bottom surface portion 12 is immersed in the paint mixed with the photocatalytic material. It may be the work of attaching.

  Thereby, the photocatalytic function can be imparted to the bottom surface portion 12 and the like, and the adhering material on the surface thereof can be decomposed to weaken the adhesion force. It can be cleaned and cleaned more effectively with rainwater that flows around the surface of the water.

  As described above, in the present embodiment, the deposit on the bottom surface portion 12 is decomposed by the photocatalyst, and rainwater or the like flowing on the surface of the front back surface portion 13 of the container 11 can be circulated to the bottom surface portion 12 to be washed away. The inner surface of the bottom surface portion 12 and the support portion 15 can be washed away and cleaned in the same manner as the front back surface portion 13 and the like. Therefore, it is possible to prevent the bottom surface portion 12 and the like from corroding much earlier than the front back surface portion 13 and the side surface portion 14 and leaking the insulating oil accommodated in the container 11 of the balancer 10 due to contamination. Maintenance costs can be reduced by eliminating the need for repainting.

  Here, in the present embodiment, a case where the bottom surface portion is inclined will be described. However, for example, even if a structure in which the non-tilted bottom surface portion is continuously connected to one of the front back surface portion and the side surface portion is used, a certain degree of effect is achieved. Although it can be expected, rainwater and the like can be actively introduced and washed away without unevenness. Therefore, it is preferable to configure as in the present embodiment and other embodiments described below.

  Next, FIG. 3 is a figure which shows 2nd Embodiment of the lower structure of the outdoor installation apparatus based on this invention. Here, since the present embodiment is configured in substantially the same manner as the above-described embodiment, the same components are denoted by the same reference numerals and the characteristic portions will be described.

  In FIG. 3, the balancer 10 is formed with a bottom surface portion 22 of a slope in which the top and bottom of the roof shape are inverted so as to descend inward from both surfaces of the front back surface portion 13. Both surfaces of the back surface portion 13 are continuous via the square shape 22a, and are formed so as to have a vertex angle 22b that is the lowest in the middle between the front and back surface portions 13. In addition, a coating film having a photocatalytic function of titanium dioxide is formed on at least the entire surface of the bottom surface portion 12 and the inner surface of the support portion 15 of the balancer 10 as in the above-described embodiment.

  Thereby, in this embodiment, not only rain water flowing on one surface of the front back surface portion 13 but also rain water flowing on both surfaces of the front back surface portion 13 is actively circulated from both sides to the surface of the bottom surface portion 22, The deposits on the surface of the bottom surface portion 22 can be efficiently washed away toward the central apex angle 22b. For example, the deposits such as seawater containing salt decomposed by the photocatalytic function can It can be washed away effectively with rain water.

  As described above, in this embodiment, in addition to the same effects as the above-described embodiment, rainwater flowing on both surfaces of the front back surface portion 13 can be circulated from both sides to the surface of the bottom surface portion 22, Surface deposits can be washed away more effectively. Therefore, corrosion of the bottom surface portion 22 and the like can be more effectively prevented, and the risk of leakage of the insulating oil accommodated in the container 11 of the balancer 10 can be reduced with higher reliability.

Next, FIG. 4 is a figure which shows 3rd Embodiment of the lower structure of the outdoor installation apparatus based on this invention.
In FIG. 4, a transformer 30 is an outdoor installation device that is placed and supported on the armrest 2 of the utility pole 1, as with the balancer 10 in the above-described embodiment. Power supply is converted to a low voltage that can be used in each home.

  As with the balancer 10, the transformer 30 contains insulating oil that immerses the device main body in a metal container 31 having a wall surface portion 33 formed in a cylindrical shape having a circular cross section. The outer surface is painted so that the insulating oil accommodated in the tank does not leak due to corrosion, and the bottom surface 12 is directly touched and damaged when placed on the floor surface or the ground during transportation and storage. In order to avoid the progress of corrosion due to this, it is formed in a raised shape like the balancer 10.

  Furthermore, the bottom surface portion 32 of the transformer 30 is formed in a spherical curved surface that descends toward the inside from the wall surface portion 33 and forms the top surface 33b at the lowest position. The wall portions 33 at four equal intervals (which may be a plurality of three or more) may be lowered (extended) below the lowermost top surface 33b to form the support portion 35. Yes. That is, the wall surface portion 33 is formed in a shape that continues to the bottom surface portion 32 between the support portions 35 via the peripheral edge 32a (does not extend downward).

  In addition, a coating film having a photocatalytic function of titanium dioxide is formed on at least the entire surface of the bottom surface portion 32 and the inner surface of the support portion 35 of the transformer 30 as in the above-described embodiment.

  Thereby, it is possible to support the bottom surface portion 32 so as not to contact the floor surface or the like with a shape that can be easily designed to function as the support portion 35 by extending only a part of the wall surface portion 33 downward. Further, by making the wall surface portion 33 continuous with the bottom surface portion 32, rainwater flowing on the surface of the wall surface portion 33 is actively (without obstructing) the surface of the bottom surface portion 32 and attached to the surface. The kimono can be washed away toward the top surface 33b. For example, as in the above-described embodiment, the deposits such as seawater containing salt decomposed by the photocatalytic function can be effectively washed away with the rainwater and cleaned. Can do.

  As described above, in the present embodiment, the transformer 30 can obtain the same effects as those of the above-described embodiment, and can effectively prevent corrosion of the bottom surface portion 32 and the like. Therefore, the risk of leakage of the insulating oil accommodated in the container 31 can be reduced with high reliability.

  Here, as another aspect of the present embodiment, as shown in FIG. 5, instead of the support portion 35 of the present embodiment, a support erected so as to be along the normal direction from the center of the bottom surface portion 32. The part 45 may be disposed at a similar location. In this case, the same operational effects can be obtained, and since the support portion 45 does not have a portion serving as an inner surface, the deposits can be washed away smoothly from the surface.

  Although one embodiment of the present invention has been described so far, it is needless to say that the present invention is not limited to the above-described embodiment, and may be implemented in various forms within the scope of the technical idea. For example, in this embodiment, the photocatalytic function is given only to the lower part of the balancer or the transformer, but it is not limited to this, and it goes without saying that it may be given to the entire surface.
