Description

{INSULATION UNIT FOR DISTRIBUTING LED POWER LINE AT APARTMENT HOUSE}

More particularly, the present invention relates to an LED distribution line isolation panel for lighting in a residential house in an indoor electrical technology field, and more particularly, The present invention relates to an LED switchgear for illumination of an apartment house which is improved to prevent a short circuit between power lines, a power failure due to a short circuit, a safety accident, and a sweeper at the bottom of a sweeper.

In the case of a common use area in apartment buildings, efficient LEDs are installed for lighting purposes to reduce power consumption.

The LED lighting lamp operates by receiving power through a power distribution line.

Generally, in case of apartment house, the amount of electricity used is very large. In order to supply electricity to each household, a pipe with a large diameter is installed in a part of the apartment house, and a distribution cable having a relatively large electric power capacity is installed inside the pipe. By such a pipe, the power distribution line is protected from external pollution and external force.

However, it is common to install not only distribution lines but also various sewage pipes inside the pipes.

Therefore, the humidity inside the pipe is generally high by the sewer pipe which always flows through the water, and when the dew is formed on the covering of the distribution line due to the high humidity or the minute crack occurs in the sewer pipe, the water is continuously sprayed on the distribution line.

If moisture is formed on the coating of the distribution line as described above, the moisture is evaporated and the moisture is formed again, so that the coating of the rubber material is hardened and cracks may occur in the coating.

If water penetrates through the gap of the coating due to the curing, there is a danger of a short circuit or a short circuit.

As a conventional technique for solving some of these problems, Korean Patent Registration No. 10-1114565 (Feb. 22, 2012), "ELDY Distribution Line Disconnecting Line for Apartment House" has been disclosed.

According to the above registered patent of the prior art, it can be seen that the power line effectively wipes the coating by wiping the moisture on the coating.

However, the conventional sweeper for water polish disclosed in the prior art has a structure in which the bottom structure has an oblong structure toward the cloth, so that there is a problem that a portion of the cloth is peeled off when moving up and down for sweeping, Respectively.

The first coupling groove 24b is formed on the upper surface of the second coupling body 24,

The first moving part 20a and the second moving part 20b are symmetrically arranged so as to surround the rotary shaft 10. The second moving part 20 and the second connecting part 23 constitute the second moving part 20b. 2 coupling body 24 is symmetrical with the shapes of the first coupling body 21 and the first coupling body 22. The shape of the second moving part 20b will not be described because the bar shape is symmetrical with the shape of the first moving part 20a described above.

The second connecting body 23 has an outer surface made of a metal material and an electromagnet (not shown) is installed inside. The electromagnets are disposed such that polarities are generated at both ends where the polarities of the permanent magnets of the first connector 21 are expressed, and particularly when the electromagnets are energized, they are arranged to generate a repulsive force with the permanent magnets of the first connector 21 . That is, the permanent magnet and the electromagnet are installed so that the polarities are respectively generated on both surfaces of the first connection body 21 and the second connection body 23 facing each other.

The second coupling member 24 is also formed with a second spacing groove having a shape symmetrical with the shape of the first spacing groove 22a on the surface facing the first coupling member 22. [

The plate 30 has a main body 31 which is installed horizontally with the power distribution line L and one end fixed to the main body 31 and the other end fixed to the first and second assemblies 22 and 24 horizontally And an arm 32.

The main body 31 is formed with a through hole 31a through which the distribution line L is passed in a rectangular frame shape and the diameter of the through hole 31a is formed larger than the diameter of the power distribution line L, It is preferable that the diameter of the through hole 31a is formed to be three times the diameter of the power distribution line L. In this case,

Therefore, air can pass through the through hole 31a simultaneously with the upward and downward movement of the main body 31. [

The arm 32 is protruded from one surface of the main body 31 facing the moving part 20 and inserted into the guide grooves 22b and 24b formed in the first and second assemblies 22 and 24 at the ends thereof A guide 32a is formed which allows the first coupling member 22 and the second coupling member 24 to be fixed in the vertical direction and movable in the horizontal direction. The guide 32a is formed to protrude in the direction opposite to each other at the end of the arm 32 having a 'C' shape.

The spacing portion 40 includes a stepping motor 42 fixedly mounted on the upper surface of the main body 31 and an elliptical portion 42 which is fixed to the rotating shaft of the stepping motor 42 and inserted in the first and second spacing grooves 22a, As shown in Fig.

The stepping motor 42 is controlled by the control unit 80 to rotate by 90 degrees at a time to rotate the cam 41.

The sweeper 50 is for wiping off moisture adhered to the surface of the power distribution line L and dividing the cylindrical shape symmetrically in the vertical direction into two halves so as to be rotatable on the main body 31 via the rotary shaft 50a . The lower end of the sweeper 50 is formed in a shape corresponding to the outer shape of the power distribution line L so as to come in contact with the power distribution line L to remove moisture adhering to the surface of the power distribution line L. [ The end of the sweeper 50, which is in contact with the surface of the power distribution line L, may be formed of a rubber material in order to more completely remove moisture from the power distribution line L. [ 1, the sweeper 50 has a cylindrical shape with an upper light-tight cone shape. When the plate 30 is downwardly sloped downward at a certain point without inclining downward, the sweeper 50 When the plate 30 moves upward, the sweeper 50 and the distribution line L are moved by the air flowing through the through hole formed in the main body 31. In this case, Thereby releasing the contact with the contact surface.

A hollow frame-like enclosure 3, which is hollow, is fixed to the inner surface of the pipe 1 at the upper end of the pipe 1. A motor 60, a battery 70, a control unit 80 and a power distribution box 2 for distributing power distribution lines to the lighting LEDs of the apartment are fixedly installed inside the housing 3.

The motor 60 is connected to the rotating shaft 10 to rotate the rotating shaft 10.

The battery 70 supplies power for operating the motor 60, the electromagnet, and the stepping motor 42.

The control unit 80 controls the operation of the motor 60, the electromagnet, and the stepping motor 42 to control the operation of the LED lighting unit for lighting of the apartment house according to the present invention. More detailed control operations will be described below. The operation of the LED distribution line insulation board will be described.

2 to 5, the operation of the lighting LED distribution line insulation board of the apartment house according to the present invention will be described. 4 (a) shows a state in which the first coupling body 22, the second coupling body 24 and the arm 32 are coupled to each other. Fig. 4 (b) (22) and the second coupling member (24) are forcibly separated from each other. 5A shows a state in which the sweeper 50 is in close contact with the power distribution line L and Fig.5B shows a state in which the close contact between the sweeper 50 and the power distribution line L is released .

Generally, in the apartment house, a pipe 1 having a large diameter is installed in a part of the building, and various pipes and electric wires are installed through the pipe 1 to protect the pipes and electric wires from the outside. In the inside of the pipe 1, a distribution line L, a water pipe and a sewage pipe are generally provided together. Water may flow on the outer surface of the power distribution line (L) installed in the same space in the pipes through which the water flows, such as a water pipe and a sewer pipe, and the moisture is evaporated and water is again added, If the distribution line breaks and becomes severe, the copper wire inside the distribution line may be exposed to the surface.

The plate 30 is fixed to the upper end of the power distribution line L when the illumination LED distribution line insulation board of the apartment house according to the present invention does not operate. That is, in this case, the first linking member 21 and the second linking member 23 constituting the moving unit 20 are closely contacted to each other by the magnetic force. As a result, the first linking member 21 and the second linking member 23 The threads 21a and 23a formed on the inner surface of the connecting body 23 and the threads 10a of the rotating shaft 10 are threadedly engaged with each other to fix the plate 30 upward.

When water on the outer surface of the power distribution line L is removed, power is first supplied to the electromagnets and power is supplied to the stepping motor 42. [ When power is supplied to the electromagnet, the electromagnet becomes magnetized, and the magnetism is expressed to have a repulsive force with the permanent magnet of the first connector 21. Therefore, the first linking member 21 and the second linking member 23 are subjected to a pushing force in the horizontal direction. The stepping motor 42 according to the present invention rotates at an angle of 90 ° each time power is supplied. When power is supplied to the stepping motor 42, the cam 41 connected to the rotation axis of the stepping motor 42 is rotated 90 ° . The rotation of the cam 41 causes the first spacing groove 22a and the second spacing groove 24a to be spaced apart from each other so that the first and second assemblies 22 and 24 are spaced apart from each other by the same distance in the horizontal direction do. The power is supplied while the electromagnet is being lowered, and the stepping motor 42 is powered only while the cam 41 is rotated by 90 degrees, and then the power is turned off. The operation of the electromagnet and the stepping motor 42 results in the threaded engagement between the first moving part 20a and the second moving part 20b and the rotary shaft 10 is released, The plate 30 fixedly connected to the moving part drops downward. The lower end of the sweeper 50 receives the resistance of the air by the fall of the plate 30 and can be more closely adhered to the power distribution line L and can wipe out the water stuck to the power distribution line L. [

When the plate 30 is dropped, the sweeper 50 may be damaged if it touches the bottom of the pipe 1, so that a detent projection (not shown) is projected from the lower end of the rotary shaft, It is possible to prevent the sweeper 50 from being damaged due to contact with the floor. In addition, a buffering member (not shown) made of a rubber material capable of absorbing an impact may be provided on the upper surface of the detent projection to prevent breakage due to collision between the moving unit 20 and the stopping projection.

When the plate 30 is dropped, the sweeper 50 may be damaged if it touches the bottom of the pipe 1, so that a detent projection (not shown) is projected from the lower end of the rotary shaft, It is possible to prevent the sweeper 50 from being damaged due to contact with the floor. In addition, a buffering member (not shown) made of a rubber material capable of absorbing an impact may be provided on the upper surface of the detent projection to prevent breakage due to collision between the moving unit 20 and the stopping projection.

After the lowering operation of the plate 30 is completed, power is first supplied to the stepping motor 42 to rotate the cam 41 by 90 degrees to insert the cam 41 into the first and second spacing grooves 22a, 24a . Since the cam 41 forcibly separating the first coupling member 22 and the second coupling member 24 is inserted into the first and second spacing grooves 22a and 24a, the first and second coupling members 22 and 24 Are brought into a state in which they are in close contact with each other. The power supplied to the electromagnets is cut off after the stepping motor 42 rotates by 90 degrees so that the first linking member 21 and the second linking member 23 are engaged by the magnetism of the permanent magnet of the first linking member . The rotation shaft 10 and the moving part 20 are threadedly engaged by the engagement of the first connector 21 and the second connector 23 and then power is supplied to the motor 60 to rotate the rotary shaft 10 To move the moving part 20 upward.

The air moves downward through the through hole 31a of the main body 31 by the upward movement of the moving part 20 and the movement of the air applies pressure to the sweeper 50, And the close contact with the power distribution line L is released. This is because water may be present on the lower end of the sweeper 50 due to the lowering operation of the plate 30 and water is added to the surface of the power distribution line L when the plate 30 rises.

When the plate 30 rises to the initial position (i.e., the position before the plate is lowered), the power supplied to the motor 60 is cut off and the plate 30 is fixed.

The control of the control unit may be performed manually by providing an external control box, or may be repeatedly performed at a predetermined time interval.

An embodiment added in accordance with the present invention based on such a configuration is an improved structure of the sweeper 50 as shown in Figs.

As shown in FIG. 6, at least one drain hole 100 is formed around the lower end of the sweeper 50.

When the sweeper 50 is lowered or lifted along the power line L, the drainage hole 100 can be removed when the water on the surface of the power distribution line L is pushed up into the sweeper 50, So that the water does not remain in the sweeper 50.

A large amount of water is pushed up into the sweeper 50 and the space inside the sweeper 50 is small so that a large amount of water is collected in a short period of time, If this is left as it is, the sweeper 50 may be filled with water. Of course, as time elapses, it will gradually drain. However, if a problem occurs in which the coating is peeled or broken in a state where the water is cold, a shot may instantaneously be short-circuited and cause a serious accident. Therefore, a drain hole 100 is formed So that it is possible to discharge the water even if a small amount of water is generated.

As shown in FIG. 7, if the sponge 200 having the shape of a donut shape cut in half is further filled in the inside of the sweeper 50, that is, the inside of the drain hole 100, It is possible to increase the effect of wiping and clean the foreign objects on the surface of the power distribution line L when ascending and descending the power distribution line 50, and to prevent moisture from being left on the surface of the power distribution line L by absorbing moisture quickly.

The sponge (200) can be easily installed by assembling the sweeper (50) in a state where the sweeper (50) is inserted before the final installation.

A pair of extending pieces 110 are downwardly protruded from the lower end of the sweeper 50 so as to be symmetrical in the radial direction.

A shaft hole 120 is formed in the center of the extension piece 110.

At this time, a hexagonal rotation prevention groove 122 is formed on the outer side of the shaft hole 120, that is, on the outer side surface of the extension piece 110, and coaxial with the shaft hole 120 and recessed to a certain depth.

The rotation preventing groove 122 is for facilitating the installation of a bearing 170 to be described later.

A saddle-type roll is provided in the shaft hole 120 of the extension piece 110. Since the extension piece 110 is formed symmetrically in both left and rear sides of the sweeper 50, The left saddle roll 130 is provided on the left extension 110 and the right saddle roll 140 is provided on the right extension.

A plurality of brushes BR protrude from the surface of the left saddle roll 130 and the right saddle roll 140 and the brush BR is brought into contact with the surface of the power distribution line L. [

In particular, the curvature of the saddle-shaped roll is formed to have a curvature corresponding to the distribution line L so as to cover the distribution line L. [

The left saddle roll shaft 132 of the left saddle roll 130 and the right saddle roll shaft 142 of the right saddle roll 140 have the same structure. For example, the left saddle roll 130 and the right saddle roll 130 140 are formed on both sides of the roll sill roll shaft 132 and the right saddle roll shaft 142. The roll sill roll 150 and the right saddle roll shaft 142 are formed on both sides thereof with a roll axial groove 150 having a positive- And the other sidewall of the left saddle roll shaft 132 and the right saddle roll shaft 142 is formed with a reverse threaded portion having a thread formed opposite to the right threaded portion FS, RS are formed.

In addition, the reverse thread RS is screwed to the bolt hole 162 having a reverse thread formed at the center of the shaft fixing hole 160, and the bearing 170 is inserted into the bolt hole 162, Respectively.

Therefore, the shaft fixing hole 160 is formed in a hexagonal shape so that the bearing 170 and the bolt hole 162 are simultaneously formed, and the outer shape of the shaft fixing hole 160 can be fitted into the rotation preventing groove 122.

The left saddle roll shaft 132 or the right saddle roll shaft 142 is inserted into the shaft hole 120 in a state where the left saddle roll 130 or the right saddle roll 140 is disposed between the pair of extending pieces 110, So that the left saddle roll 130 or the right saddle roll 140 can be axially fixed on the shaft hole 120 by fastening the positive thread FS to the positive thread of the roll shaft groove 150 by passing the positive saddle FS.

In this state, the left saddle roll shaft 132 or the right saddle roll shaft 142 is fastened to the bolt hole 162 with the shaft fixing hole 160 inserted into the rotation preventing groove 122, When the left saddle roll 130 or the right saddle roll 140 is turned in the opposite direction, the bolt hole 162 and the left saddle roll shaft 132 or the right saddle roll shaft 142 are screwed to each other.

Since the shaft fastening hole 160 and the left and right saddle rolls 130 and 140 are always fastened in opposite directions when the fastening screw 160 is fastened, the pulling force that is not artificially loosened is not easily released, Since the left saddle roll shaft 132 or the right saddle roll shaft 142 is smoothly guided so that the left saddle roll 130 or the right saddle roll 140 smoothly rotates smoothly .

In addition, if such a structure is provided, the left and right saddle rolls 130 and 140 can be easily replaced, if necessary, thereby facilitating maintenance.

In addition, as shown in FIG. 7, a rectangular damper body 300 is further fixed to the lower end of the extension piece 110.

A damper rod 310 is vertically fixed to a lower end of the damper rod 310 and a lower end of the damper rod 320 is vertically fixed to a lower end of the damper body 300. The limit switch 330 is fixed.

At this time, the limit switch 330 is configured to send a detection signal when it contacts the damper body 300, and is electrically connected to the controller 80.

When the damper rod 310 is pushed and pressed into the damper body 300 when the sweeper 50 is excessively lowered and brought into contact with the floor surface, when the limit switch 330 is pressed to the damper body 300 .

In this process, the limit switch 330 operates, and the control unit 80, which senses the electric signal at that time, stops driving the motor 60 to stop the descent of the sweeper 50, It is possible to safely protect it from breakage.

As described above, the present invention can further securely and smoothly maintain the distribution line L by further configuring a plurality of safety devices and a cleaning device.
