Description

Construction method of indoor conduit protection facility with electric shock prevention outlet

The present invention relates to a method of constructing an indoor conduit protection device to which an electric shock prevention outlet is applied to prevent an electric shock in an electric field of a multi-family house such as an apartment and a multi-family house, and may be caused by mischief caused by iron chopsticks of a curious child. A method of constructing an indoor conduit protection device with an electric shock prevention outlet to protect the conduit so that an operator can easily recognize a situation where the conduit will be damaged for the stable supply of electric power while preventing electric shock accidentally. will be.

In general, in the electrical construction of buildings, in the case of electricity, electrical boxes (outlets) are interconnected with each other, embedded in a wall, etc., and finished by a plasterer, etc. It is not easy to know.

For this reason, nails or nails are installed on the wall to install household goods such as wall clocks, or electric lights are installed on the ceiling. And there was a risk of leakage.

Thus, when nails are nailed to a conventional wall, a problem arises in that the nail nailed to the wall damages the wire while damaging the conduit.

In order to solve this problem, the pipe detector was used to find the pipe, but it was time-consuming and could not be easily found in the case of the non-metallic pipe material, especially because it is expensive and it is difficult to purchase at home. .

According to this, a pipe protection device for protecting an electric wire has been applied, but such a pipe protection device is induced to slip to the side when nailed. However, in the case of an electric drill, the protection of the conduit is difficult because it proceeds through the pipe protection device. Occurs.

Therefore, when nailed to the wall with a nail or a power drill, where there is a wire pipe, if a nail or a power drill comes into the wall, it was necessary to give a warning that can be easily known to completely protect the wire piping.

Although such a protection means is disclosed in Korean Patent Publication No. 10-0988248 (Electrical pipe protection device of a common house wall), but the configuration is complicated, the auxiliary plate connected to the main body does not slide smoothly, the contact is not made. It was.

In addition, the outlet that is installed in the wall to supply power to the outlet for preventing electric shock accidents is to prevent electric shock accidents by inserting chopsticks into the outlet holes of infants and children. Has already been developed.

Such an electric shock prevention type outlet of a multi-family house allows power to be applied to the electrode only when the operation switch provided in the case is pressed, and infants or children do not press the operation switch provided in the case, such as chopsticks in the coupling hole. When the rod is forcibly inserted to rotate or bend, the audio data including a warning message is output to prevent an electric shock from occurring and at the same time, the infant and the child are no longer forced to chopsticks or the like. There is an advantage that can be repetitively trained so as not to insert the product, but if you forcibly insert chopsticks into the joining hole, it is difficult to prevent the electric shock accident, so the basic power distribution system to prevent electric shock accidents of curious children Technology development is in good shape.

Patent Registration No. 10-0988248 "Electrical piping protection device of the wall of the common house" Patent Registration No. 10-0955064 "Electric shock accident prevention outlet of a public house"

Referring to the construction method of the present invention installed as described above in more detail through the drawings as follows.

1) Manufacturing Step of Angle Blocked Steel Sheet

The angle-blocking iron plate 30 is made of a metal strip shape that can withstand the vertical strength caused by the hit of the nail / power drill 60, etc., is formed by the angle of the "b" shape by bending the strip shape. .

Therefore, when the nail / power drill 60, etc., penetrated by the operator contacts the angle-blocking iron plate 30, the angle-blocking iron plate 30 is slid to both sides so that the conduit 20 installed in the lower part can be deviated. Make in advance.

2) Manufacturing Step of Penetration Detector

The penetrating sensing unit 40 is configured to detect penetration of the nail / power drill 60, and is formed in a strip-shaped rectangle at regular intervals between the upper conductor 41 and the lower conductor 42 at the upper and lower portions thereof. Install and manufacture. At this time, the upper conductor 41 and the lower conductor 42 are thin foil conductors, preferably aluminum foil.

In addition, it is natural that the width of the strip-shaped through-detection portion 40 is wider than the diameter of the conduit tube 20 provided at the lower portion.

And each of the upper conductor 41 or lower conductor 42 is manufactured to be connected to the switch terminal for operating the notification unit 50.

The notification unit 50 sounds an alarm by the notification unit 50 when it is detected that the nail penetrates the penetration detecting unit 40. The nail penetrates the nail if the nail penetrates the penetration detecting unit 40. The upper conductor 41 and the lower conductor 42 are conducted by the drill 60, and thus, between the upper conductor 41 and the lower conductor 42 connected to the ON / OFF switch terminal of the amplifier circuit of the notification unit 50. The amplifier circuit is actuated by the conduction to produce an alarm sound by the notification unit 50 (the specific circuit is omitted since such amplifier circuit is a general technique).

The outer conductor is interposed between the upper conductor 41 and the lower conductor 42, and the outer surface is manufactured to be wrapped or sealed coated 45.

At this time, the insulator 43 prevents the upper conductor 41 and the lower conductor 42 from being electrically connected to each other.

In addition, the insulator 43 may be impregnated with a liquid 44 in which pigments such as red, blue, and yellow are dissolved, and the insulator 43 impregnated with the liquid 44 may be a liquid (such as sponge, cotton, or hemp). 44) It may be an object capable of absorbing, and it is preferable to use the natural fibers recycled waste clothing to utilize waste resources.

The liquid 44 is an insulating oil which is an electrically nonconductive material. Preferably, the liquid 44 is used as waste cooking oil in order to recycle household waste resources.

In the case where the liquid phase 44 is a non-conductor, the liquid phase 44 impregnated in the insulator 43 between the upper conductor 41 and the lower conductor 42 becomes a conductor in the case of a general liquid, so that the upper conductor 41 and the lower conductor ( 42) because it does not function to detect infiltration of nails.

In addition, the outer surface of the through-sensing part 40 via the insulator 43 in which the liquid 44 in which the dye is dissolved is impregnated between the upper conductor 41 and the lower conductor 42. In order to prevent leakage or evaporation, it is preferable to wrap or seal the coating 45 with a waterproof material such as vinyl.

In addition, the sealing coating 45 of the outer surface of the penetration detection unit 40 is embedded in the wall through the penetration detection unit 40, after several hours the liquid 44 is leaked or evaporated to detect the function This is to prevent falling.

3) Conduit construction stage

In the electrical and telecommunication construction of the building, in the case of electricity, the electrical conduits (outlets) are interconnected with each other and the conduit 20 is installed to be embedded in the wall 10, etc.

4) Construction of Angle Blocked Steel Sheet

In order to protect the conduit 20 embedded in the wall 10, the produced angle-type shielding iron plate 30 to the front spaced apart.

At this time, the interval is good to install 0.5 ~ 2Cm to protect the conduit (20). However, the numerical value is not limited, and any interval may be used to protect the conduit 20.

5) Construction of penetration detection unit

In order to protect the conduit 20 is provided with a pre-fabricated through-sensing portion 40 to notify the visual and audio of the position notification of the conduit 20 at intervals in front of the angle-blocked iron plate 30 installed. . The interval is also good to install 0.5 ~ 2cm.

At this time, the notification unit 50 connected to the through-sensing unit 40 may be embedded in the wall 10, it is preferable to be installed horizontally on the surface of the wall 10 to generate a warning sound indoors.

6) Wall finishing step

In order to protect the conduit 20, when the installation of the angle-blocking iron plate 30 and the penetration detection unit 40 is finished, the wall 10 is plastered with mortar and finished, and finished with a final finish such as wallpaper or tile. Construct

The operating state of the indoor conduit protection system constructed as described above is as follows.

When the nail / power drill 60 penetrates the penetration sensing unit 40 in the process of drilling a hole with the nail / power drill 60 to install household goods or a lamp on the wall 10 or the ceiling, the notification unit ( 50) Make this alarm sound.

That is, since each switch terminal for operating the notification unit 50 is connected to each of the upper conductor 41 and the lower conductor 42 of the penetration detecting unit 40, the nail / power drill 60 penetrates into the penetration detecting unit. When the upper conductor 41 and the lower conductor 42 are conducted by the nail / power drill 60 penetrated, the upper conductor 41 and the lower end connected to the ON / OFF switch terminal of the amplifier circuit of the notification unit 50 The amplifier circuit is operated by the conduction between the conductors 42 is to sound the alarm by the alarm unit 50. Therefore, the worker hears the alarm and stops the work by knowing the position of the conduit 20.

On the other hand, if you do not hear the alarm sound of the notification unit 50 due to the noise of the construction, the gap between the nail / power drill 60 and the upper conductor 41 and the sealing coating 45 penetrating through the through-sensing unit 40. By the color liquid 44 is ejected between the operator visually notice that there is a conduit tube 20 at the bottom and stop the work.

Nevertheless, the operator cannot recognize the position of the conduit 20 through the liquid phase 44 or the alarm sound, but the nail / power drill 60 or the like moves forward to the position of the conduit 20 through the wall 10. While contacting the angle-shaped blocking iron plate 30 provided at intervals in front of the (20) is to be slid to both sides of the conduit (20) to prevent the breakage or breakage of the conduit (20).

It is preferable to connect the neutral line (N) of the power supply to the front end portion.

In addition, if the voltage applied to the neutral line (N) is 1 to 5 [V] like the normal voltage (potential), an electric shock does not occur even if the human body contacts the neutral line (N). When an abnormal voltage is applied to the voltage, an electric shock may occur even in the above-described configuration of the present invention, so that a potential difference detection blocking unit 140 is added to block the abnormal voltage from being applied to the neutral line N, and the potential difference detection blocking unit As shown in FIG. 7, the potential difference detector 141 is connected between the ground electrode 134 of the outlet and the neutral line N so that the potential difference greater than a set value is detected by the potential difference detector 141. The power connected to 121a) and the main terminal 111a is cut off. The ground electrode 134 of the outlet is a ground electrode connected to the ground wire, which is an essential component in the outlet.

As shown in FIG. 7, the + terminal of the potential difference detector 141 is connected to the neutral line N of the power supply line, and the ground terminal 134 of the cone center is connected to the − terminal of the potential difference detection block 140. When the electric potential [V] of the neutral wire N becomes equal to or higher than the set value, the power cutoff relay 143 is operated by the signal of the MCU 142 to cut off the power. That is, when the voltage [V], which is the potential difference between the neutral line N of the power supply line supplied to the outlet and the ground electrode 134 grounded to the ground, is greater than or equal to the set value, the power cutoff relay 143 is operated. Where Vcc / Vee is the power source for operating the potentiometer.

The potential difference detection block 140 may control the set voltage at which the power is cut, that is, the power cutoff relay 143 is operated.

The set voltage that cuts off the power at the potential difference detection block 140 may be adjusted to 10 [V], 15 [V], 20 [V], 25 [V], 30 [V], etc. In consideration of the fact that the safety allowable contact voltage is 30 [V] or less (Article 324 of the Regulation on Occupational Safety and Health Standards) without the risk of electric shock when touching the human body, it is desirable to set the power cutoff voltage to 30 [V]. The potential difference detection blocking unit 140 is preferably installed in the outlet.
