Description

Technology Field

[0001] The present invention relates to a sealed flood-prevention enclosure, and more specifically, to a sealed flood-prevention enclosure that can prevent water from entering the interior of the enclosure when road flooding occurs and can expand the storage space area of ​​the enclosure according to changes in internal pressure. Background Technology

[0002] Generally, electrical equipment enclosures are installed on roads to step down high-voltage power supplied from substations to commercial voltage and supply it to consumers.

[0003] The above enclosure consists of an enclosure body that forms a storage space to accommodate power components inside, and an opening and closing door installed on the enclosure body.

[0004] In addition, a cable penetration hole is formed in the main body of the above-mentioned enclosure to allow a current cable to pass through.

[0005] As shown in FIG. 1, the outer body (10) is installed on the foundation concrete (13), and a cable penetration hole (13h) is formed in the foundation concrete (13) through which a current cable (11) enters and exits the outer body (10), and then the power cable (11) is fixed in the cable penetration hole (13h) and the cable penetration hole (13h) is closed using a hole-filling member (14).

[0006] The hole-filling member (14) of the prior art is designed to wrap around a portion of the longitudinal direction of the current cable (11). Since there is a significant difference in diameter depending on the specifications of the power cable, there is an inconvenience in having to prepare hole-filling members of various sizes at once and selecting the one suitable for the specifications of the work site.

[0007] Furthermore, when using the aforementioned hole-filling material, there is a structural problem in that it cannot fundamentally block water intrusion in the event of a road flood.

[0008] In addition, there was no solution at all for the problem of moisture infiltration when workers opened and closed the doors for work.

[0009] In addition, during the summer, a large amount of heat is generated due to high temperatures and power overloads. This high temperature increases the air pressure inside the transformer, and if the internal air pressure deforms the enclosure or exceeds the pressure it can withstand, it leads to the problem of the enclosure being damaged.

[0030] As described above, the sealed flood-prevention enclosure according to the present invention comprises: an enclosure body (100) forming a storage space (101) for accommodating power components; a base support (200) supporting the enclosure body (100) at a certain height above the ground; an opening / closing door (300) capable of opening and closing the storage space (101) of the enclosure body (100); a heat dissipation means (400) for dissipating heat generated within the enclosure body (100); a dehumidification means (500) installed on the opening / closing door (300) for collecting moisture and condensation generated in the storage space (101); a sealed cable gland (600) for tightly sealing and fixing a power cable (C) introduced from the bottom surface of the enclosure body (100); and a retractable space installed on the upper part of the enclosure body (100) to expand the area of ​​the storage space (101) when the internal pressure of the storage space (101) increases. It is configured to include an expansion means (700).

[0031] First, the above-mentioned outer body (100) is installed outdoors and is a structure assembled in a box shape by combining a plurality of flat plates.

[0032] Inside the above-mentioned outer body (100), a storage space (101) is formed to accommodate a power cable (C) introduced from the outside and electrical devices for distributing or switching power.

[0033] That is, the above-mentioned outer body (100) safely protects power-related electrical devices installed inside and at the same time prevents the wires connecting various on-off switches from being exposed to the outside, thereby preventing safety accidents such as electric shock.

[0034] In addition, a through hole or a plurality of through holes are formed in the upper plate of the above-mentioned outer body (100) to communicate with the space expansion means (700) to be described later.

[0035] In addition, a cable inlet hole (110) into which the power cable (C) is introduced is formed on the bottom surface of the above-mentioned outer body (100) (see FIG. 4).

[0036] The base support (200) is intended to separate the outer body (100) from the ground at a certain height, and serves to allow the outer body (100) to be positioned higher than the ground without the need to create separate foundation concrete.

[0037] It is preferable that such a base stand (200) be made with the same width and height as the outer body (100).

[0038] And a fixing bracket (210) is installed on each corner of the base support (200) so that it can be firmly fixed to the ground using a wedge or a fixing bolt.

[0039] The above-mentioned opening / closing door (300) is installed on the front or on both the front and rear sides of the above-mentioned enclosure body (100), and performs the function of enabling the storage space (101) of the above-mentioned enclosure body (100) to be opened and closed.

[0040] And the above-mentioned opening / closing door (300) can be installed as a single-door or double-door hinged structure depending on the size of the above-mentioned enclosure body (100).

[0041] Of course, the above-mentioned opening and closing door (300) may also be manufactured with a sliding configuration.

[0042] In addition, the above-mentioned opening and closing door (300) may be equipped with a display window (310) that allows visual observation of the storage space (101) of the above-mentioned outer body (100).

[0043] In addition, a sealing member (320) is installed on the perimeter of the back side of the opening / closing door (300) so that a tight sealing state is maintained without any gaps occurring between the outer body (100) and the opening / closing door (300).

[0044] Meanwhile, the heat dissipation means (400) is installed at the upper and lower parts of the outer body (100), respectively, and performs the function of dissipating heat generated within the outer body (100).

[0045] Specifically, one of the heat dissipation means (400) is installed on the end plate (720) of the space expansion means (700) installed on the upper part of the outer body (100), and the other one is installed on the lower plate.

[0046] The above-mentioned heat dissipation means (400) is composed of a double heat dissipation plate in which the outer heat dissipation plate (410) and the inner heat dissipation plate (420) are in surface contact with each other.

[0047] The above double heat sink allows the inner heat sink (420) to quickly receive heat emitted from the electrical device, and the outer heat sink (410) can quickly release heat conducted from the inner heat sink (420) to the outside air.

[0048] In addition, it is preferable to further configure a cover box (120) in the above-described outer body (100) to protect the heat dissipation means (400) and space expansion means (700) installed on the upper plate from being exposed to the outside.

[0049] The above dehumidification means (500) is installed on the opening / closing door (300) and performs the function of collecting moisture and condensation generated in the storage space (101).

[0050] In other words, the dehumidifying means (500) performs the function of removing moisture present in the outer body (100) by adsorbing it, or removing moisture generated from condensation caused by the temperature difference with the outside. Therefore, it is possible to prevent damage to various electrical devices within the switchboard in advance, as well as to prevent electrical safety accidents and fires that may occur due to leakage current caused by moisture and condensation.

[0051] Specifically, the dehumidification means (500) comprises a storage case (510) having an opening formed at the top and a plurality of slit grooves (511) formed on the front, and a dehumidification cartridge (520) stored in the storage case (510).

[0052] Meanwhile, the above-mentioned sealed cable gland (600) is installed in the cable inlet hole (110) of the above-mentioned enclosure body (100) and serves to tightly seal and secure the power cable (C), thereby fundamentally blocking foreign substances or water from entering through the cable inlet hole (110).

[0053] The sealed cable gland (600) according to the present invention comprises a fixed body (610) having a through hole (611) formed inside, wherein the lower part of the through hole (611) forms a hopper inclined portion (612) that becomes narrower towards the bottom, and a plurality of fastening portions (613) formed on the lower part of the outer circumference; a compression sleeve (620) seated on the hopper inclined portion (612) and having a cable through hole (621) formed in the center inside; and a sleeve pressure bolt (630) which is screw-fastened from the upper part of the through hole (611) of the fixed body (610) and presses the compression sleeve (620) to allow compression deformation to occur.

[0054] Additionally, a first water-prevention O-ring (640) is installed in the circumferential direction between the lower through hole (611) and the fastening part (613) of the fixed body (610), protruding outward from the bottom surface of the fixed body (610), and a second water-prevention O-ring (650) is installed between the fixed body (610) and the sleeve pressure bolt (630).

[0055] In addition, a pressure-applying inclined portion (631) is formed on the lower inner side of the body portion of the sleeve pressure bolt (630) to guide the compression sleeve (620) to be pressed in a direction toward the power cable (C).

[0056] As shown in FIG. 5, the sealed cable gland (600) provides the effect of fundamentally blocking external foreign substances or water from entering through the power cable (C) by ensuring that the compression sleeve (620) is completely and tightly adhered to the outer surface of the power cable (C) during the compression process when the sleeve pressure bolt (630) applies pressure to the compression sleeve (620).

[0057] Meanwhile, the space expansion means (700) is installed on the upper part of the outer body (100) and is a component that expands and contracts to expand the area of ​​the storage space (101) when the internal pressure of the storage space (101) increases.

[0058] That is, the space expansion means (700) allows the storage space (101) of the outer body to expand the area of ​​the storage space (101) by means of the space expansion means (700) when the air pressure increases due to high temperature in the summer and power overload, thereby providing the effect of minimizing accidents in which the outer body (100) is deformed or damaged by high temperature pressure.

[0059] Specifically, the space expansion means (700) is installed on the upper plate of the outer body (100) and communicates with the storage space (101), and is composed of an expandable body (710) that can be expanded in the vertical direction, a plate-shaped finishing plate (720) installed on the upper part of the expandable body (710), a guide shaft (730) that is fitted and coupled to each corner of the finishing plate (720) to guide the finishing plate (720) in a straight direction, and a stopper cap (740) coupled to the upper end of the guide shaft (730).

[0060] That is, the space expansion means (700) can fold or extend the expandable body (710) as the end plate (720) moves up and down along the guide axis (730). And the stopper cap (740) performs the function of preventing the end plate (720) from detaching from the guide axis (730) during the process of moving upward.

[0061] In addition, a spring (750) that elastically supports the end plate (720) is installed on the outer surface of the guide shaft (730).

[0062] In addition, the above-mentioned finishing plate (720) has a heat dissipation means coupling hole (721) formed therein, in which the heat dissipation means (400) is installed.

[0063] And a foldable corrugated portion is formed on the outer surface of the above-mentioned flexible body (710).

[0065] The present invention described above is not limited by the aforementioned embodiments and attached drawings, and it will be obvious to those skilled in the art that various substitutions, modifications, and changes are possible within the scope of the technical concept of the present invention.
