Hereinafter, the operation of the protective distribution enclosure of the underground distribution line according to the present invention with reference to Figures 2, 3 and 5 are as follows.

In the normal state, the rotating member 200 has an opening and closing plate 220 is disposed on the exit side of the manned passage (111b), the exit side of the manned passage (111b) is closed, the lighting unit 1100 is turned off Is installed.

As shown in Figure 2 and 5, when the rat intrudes through the wire inlet 111a, it is attracted to the handout to enter the attracting passage (111b). At this time, the intrusion detection unit 300 detects this and outputs a detection signal to the control unit 1000.

As shown in FIG. 3, when a detection signal is input from the intrusion detecting unit 300, the control unit 1000 supplies power to the electric shock unit 600 and operates the current detection unit 700. Then, the current detection unit 700 outputs the current detection signal detected from the electric shock unit 600 to the control unit 1000. Subsequently, the rat attracted to the exit side of the attraction passage 111b by the handout moves to approach the handout, and then touches the electric shock unit 600 to receive an electric shock. At this time, the current flowing through the conductive wire 610 of the electric shock unit 600 is changed in size due to the contact of the mouse. The control unit 1000 compares the current detection signal input from the current detection unit 700 with the second reference signal. And, if the difference between the current detection signal and the reference signal is more than the set range, the control unit 1000 cuts off the power supply to the electric shock unit 600 and the current detection unit 700 after a predetermined time. Then, the control unit 1000 operates the drive unit 800, and rotates for a predetermined time so that the bottom plate 210 of the rotating member 200 is disposed perpendicular to the bottom portion 111, the opening and closing plate 220 The inclined surface 221 of the main body 110 is exposed to the outside. Then, the electrocuted rat is automatically discharged to the outside by falling on the inclined surface 221 of the opening and closing plate 220 exposed to the outside. Therefore, the worker can easily handle the rat discharged to the outside of the protective case 100.

However, in the state in which the rat penetrates into the manned passage 111b and the electric shock unit 600 is operated, unexpected flooding may occur. At this time, when submerged more than a certain height, when the electric shock unit 600 is operated, a short circuit occurs through the conductive wire 610. However, in the distribution box according to the present invention, even if the electric shock unit 600 is in operation, if the rain is more than a certain height due to the flooding, the control unit 1000 is the electric shock unit 600 through the input rain detection signal Stop the power supply.

In addition, as described above, during inundation, the rat invading into the manned passage (111b) can run away from the handout without electrocution. As such, if the handout is missing or broken, there is a risk that the mouse will not be attracted later. At this time, the control unit 1000 is turned on the lighting unit 1100, because the magnitude of the weight detection signal input from the weight detection unit 400 is less than a predetermined size than the first reference signal, the replacement and refilling time of the handout Informed by. When the lighting unit 1100 is turned on, when the operator grasps the handle 222 and descends downward along the radius of curvature, the driving motor 810 is forcibly rotated and the rotating member 200 is rotated. Therefore, the handout receiving part 500 may be exposed to the outside to supplement the handout. Then, when the handle 222 is pushed in the opposite direction along the radius of curvature, the rotating member 200 is rotated in the opposite direction to its original position.

The distribution box for protecting the underground distribution line according to the present invention configured as described above is easy to use because it does not need to install a separate rat catching means by the self-capturing rat catching means.

In addition, the distribution box for protection of the underground distribution line according to the present invention, the rotation member 200 is rotated, even without a separate confirmation procedure, the electrocuted rats are automatically discharged to the outside has the advantage of easy processing of the captured rats.

In addition, the protective distribution box of the underground distribution line according to the present invention, when flooded more than a certain height, the electric shock unit 600 is not operated, so a short circuit is also prevented.

In addition, the distribution box for protecting the underground distribution line according to the present invention, the weight sensing unit 400 and the lighting unit 1100 is provided, so that it is convenient to know the replacement and replenishment time of the handout, replace the handout at an appropriate time It can also be supplemented, so you can continue to capture mice.
