BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower opening type power distribution box having a flooding prevention function, and more particularly, to a lower opening type power distribution box having a flooding prevention function to prevent the power distribution box from being flooded by blocking the lower portion of the power distribution box.

The conventional lower open type distribution box is provided with a lower opening space for introducing a lead wire and a power distribution line downwardly. When a cover is closed and locked by providing various kinds of packing for preventing flooding on a lead wire, a power distribution line and a cover of a power distribution box, To prevent flooding and so on.

However, since the flooding prevention structure is mainly composed of soft rubber as a packing material, the packing is gradually hardened and the sealing function can not be performed properly. Therefore, when a natural disaster such as flood occurs, the distribution box is flooded.

Due to this problem, a lower opening type power distribution box having a penetration prevention function for preventing water from penetrating inside the cabin has been developed.

An example of this is disclosed in Korean Patent No. 10-1048583 (hereinafter referred to as "Prior Art Document 1").

1 is a view showing the inside of a distribution box having a conventional flooding prevention structure disclosed in the prior art document 1.

1, a conventional cabinet has a curtain 200 installed above the enclosure 100. The curtain 200 is installed at the lower end of the curtain 200 so that the curtain 200 can be quickly and accurately lowered when the curtain 200 is lowered. And is held in a folded state in order to reduce the space required for storage. The frame 201 of the curtain 200 has a structure in which it is caught by the protruding and retracting projections 300 protruding from the fixed lid 102 and prevented from falling down in order to prevent falling down. Here, the detaching / detaching unit 300 is connected to the other end of the rotation float 403 of the first float 301 for detecting the flooding of the enclosure and the steel wire 303. The first float 301 rises and the first float rises, the rotation axis 403 rotates with respect to the central axis, and the steel wire 303 is moved downward as viewed in the drawing So that the outer appearance of the cabinet 300 is moved to the inside of the stationary frame 102 and the frame 201 placed on the cabinet 300 is dropped due to its own weight and the inside of the cabinet 200 is moved outside .

In addition, the distribution box is configured to form a positive pressure inside the distribution box to prevent water from penetrating through the entrance 600, which is a wiring. That is, when the second float 400 rises, the rotation path 403 rotates. When the rotation path 403 of the second float 400 rotates, the other end of the rotation path 403 is connected to the pneumatic valve 401 So that a positive pressure is formed inside the cabin. Here, the pneumatic valve 401 is communicated with the pneumatic pressure generating means (not shown) through the pipe 701.

However, it is almost impossible to form a positive pressure inside the power distribution box to prevent penetration of water when the size of the power distribution box is large or the wiring inlet hole is large.

There is a problem that the capacity of the pneumatic pressure generating means becomes excessively large even if positive pressure is formed inside the cabin.

Especially, in the case of nuclear power plants or steel mills, it is necessary to supply electricity even if inundation occurs. However, there is a problem that when the powertrain is flooded due to inundation, enormous damage occurs.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a lower opening type power distribution box having a flood prevention function according to the present invention will be described with reference to the accompanying drawings.

FIG. 2 is a perspective view showing a lower opening type power distribution box having a flooding prevention function according to the present invention, and FIG. 3 is a sectional view showing a substantial part of a lower opening type power distribution box having a flooding prevention function according to the present invention.

As shown in FIGS. 2 to 3, the lower opening type power distribution box having a flooding prevention function according to an embodiment of the present invention includes a housing 10 having a wiring inlet 12 at a lower portion thereof, (20) for injecting a foaming agent into the housing (22), a flood sensing means (30) formed in the wiring inlet (12) of the housing (10) And a control unit (40) for controlling the blowing agent dispensing means (20) when it is detected.

The housing (10) is formed in the space, and a plurality of coupling parts for electrical connection and pre-installation of modules, bus bars, and the like for power reception and distribution can be installed in the space. A door 14 is formed on the front surface of the housing 10 to block the inside of the housing 10 from the outside. A wiring inlet 12 is formed in a lower portion of the housing 10. The electric wire 16 passes through the wiring inlet port 12 so that electricity can be received and distributed.

In addition, a curtain (18) for blocking the inside of the housing from the outside is installed inside the housing (10) when flooding. The curtain 18 is normally fixed in a folded state, but the curtain 18 is lowered by its own weight under the control of the control unit 40 when the float is flooded, thereby blocking the inside and the outside of the enclosure 10. The curtain 18 is formed with a weight 19 at its lower portion so as to descend freely by its own weight. The curtain 18 is provided inside the corresponding body of the weight 19 in order to prevent the curtain 18 from falling freely. A projecting pin 17 controlled by the control unit 40 is formed. It is preferable that the projecting pin 17 is provided so as to be retracted into the housing by a solenoid (not shown) when a signal is transmitted to the control unit 40 from the housing 15.

A wall 13 is formed in the wiring inlet 12 of the housing 10 along the rim. This wall 13 is formed in order to prevent the announcement index at the time of flooding from being lost due to scattering when it is put into the wiring inlet 12. [ At the same time, the wall 13 prevents water from overflowing for a predetermined period of time even if the water rises inside the enclosure 10.

The foaming agent dispensing means 20 is provided to inject the foaming agent into the wiring inlet 12 of the housing 10. The foaming agent dispensing means 20 includes a chute 22 formed around the wiring inlet 12, a foaming agent tank 24 formed on the upper portion of the chute 22, 24 and a gate 26 provided between the chute 22.

The tip of the chute 22 is inclined downward toward the wiring inlet 12 to guide the foaming agent discharged from the chute 22 to the wiring inlet 12 smoothly.

The foam exporter tank 24 is installed on the chute 22. The foaming agent to be stored in the foaming agent tank 24 is preferably a urethane foaming agent. As an example of the foaming index agent, WS5000S sold by Esji may be used. The foaming agent reacts with water and air to form a foam and cures within 5 minutes to completely block wiring inlets. The foaming agent tank 24 is provided with a vibrator 25 for vibrating the foaming agent tank 24 for smooth discharge of the foaming agent.

The gate 26 is provided at the lower portion of the foam exporter tank 24 to open and close the entrance and exit of the foamed resin product. Wherein the gate 26 is actuated by a drive cylinder 27. That is, it is possible to open and close the entrance and exit of the foaming agent according to the elongation and contraction of the drive cylinder 27.

The immersion sensing means (30) is formed in the wiring inlet (12) of the enclosure (10). In this embodiment, the water immersion sensing means 30 is provided at the lower part of the wire inlet 12, and can secure a curing time for reacting the foam index agent with water when the water starts to flow.

The controller 40 activates the foaming agent dispensing means 20 when it is detected that water is coming from the flood sensing means 30. That is, when a flood signal is sensed from the immersion sensing means 30, the driving cylinder 27 of the gate 26 is operated to open the gate 26. [ At the same time, the projecting pin 17 supporting the weight 18 of the curtain 18 is moved to the inside of the housing 15 so that the curtain 18 is lowered by its own weight.

As described above, the operation of the lower open type distribution box having the flooding prevention function according to the embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 4 is a view showing a state in which a foaming index agent is injected into a lower open-type distribution box having a flooding prevention function according to the present invention. FIG. 5 is a cross- Fig. 8 is a view showing a state in which the wiring inlet is closed.

A sensing signal is transmitted to the control unit 40 when immersion is detected from the level sensing unit 30 disposed at the lower portion of the wiring inlet 12. [

When the immersion sensing signal is transmitted to the controller 40, the controller 40 operates the driving cylinder 27 so that the gate 26 is opened. When the driving cylinder 27 is operated and contracted, a foaming agent is injected into the wiring inlet 12 along the chute 22 as shown in FIG. At this time, the vibrate 25 operates to allow the foaming agent to smoothly enter from the foaming agent tank 24.

When the foaming agent is injected into the wiring inlet 12 along the chute 22, the foaming agent starts foaming with water and air. When the foaming agent expands for a predetermined period of time, it completely hardens as shown in FIG. 5 to completely block the wiring inlet port 12, so that the inflow of water through the wiring inlet port 12 is blocked.

When the flood sensing signal is transmitted to the control unit 40, the control unit 40 causes the projecting pin 17 supporting the weight 19 of the curtain 18 to retract into the interior of the housing 15, (18) is lowered by its own weight so that the enclosure (10) is shielded from the outside.

Thus, even if a natural disaster such as a flood occurs, it is possible to operate necessary facilities such as a pump (not shown) to easily overcome a disaster.

Next, if the water that has been submerged is removed, physical means may be used to remove the foamed foaming agent and reuse the distribution box.
