The driving unit 930 serves to elevate the elevator platform 920 by receiving an operation signal from a separate remote controller (not shown) carried by the operator, and includes a pinion 931 and a motor 932.

For example, the pinion 931 and the motor 932 are installed in a separate storage box (see FIG. 5) and installed in an installation groove (see FIG. 5) formed on the outer peripheral surface of the entrance 112 to communicate with the inside.

The pinion 931 is installed to be engaged with the rack 921 of the lifting platform 920 and rotated together when the motor 932 rotates in the forward (or reverse) direction to lift the rack 921 (up and down).

The motor 932 is a conventional servo motor operated by a control signal. In this embodiment, the motor 932 serves to rotate the pinion 931 fitted to the motor shaft in the forward or reverse direction.

The second lift mechanism 1000 is installed to be suspended from the support 922 constituting the first lift mechanism 900, and the operation is controlled by receiving an operation signal from the operator's operation or the control unit 800 to control the underground power distribution line (L). It serves to withdraw the connected wire connector 300 to the outside through the entrance 112.

6 is a view for explaining the operation of the underground distribution line arrangement tray device with improved safety according to the present invention, and will be described with reference to this.

As shown in FIG. 1, when a tensile force is applied to the underground distribution line L accommodated in the electric wire pipe 200 in the installed state, the underground distribution line take-up mechanism 500 is in the direction in which the tensile force acts as shown in FIG. At this time, the spring 430 is compressed by the moving underground distribution line winding mechanism 500 to receive a tensile force acting on the underground distribution line L.

On the other hand, when the tension applied to the underground distribution line L is released, the underground distribution line take-up mechanism 500 moves toward the tray unit 113 along the guide rod 420 by the restoring force of the spring 430.

Accordingly, since the connection portion of the underground distribution line L can fundamentally solve the short-circuit problem by the above-described action, the safety of the hypothesis state of the underground distribution line L can be improved.

7A and 7B are views for explaining another operation of the underground distribution line arrangement tray device with improved safety according to the present invention, and will be described with reference to this.

In the case of replacing the old wire connection device 300 in the installed state as shown in FIG. 1, the operator removes the lid 120 blocking the access part 112.

Is rotated to rotate the pinion 931, and the rack 921 engaged with the pinion 931 is lifted (moved up and down) by the rotation of the pinion 931.

In addition, as the rack 921 moves up and down, the support unit 922 integral with the rack 921 is raised and lowered, and the second lift mechanism 1000 suspended from the support unit 922 due to the lifting of the support unit 922 This naturally goes up and down (up and down).

At this time, the rope 1010 of the second lift device 1000 is interconnected with the wire connection device 300 via the hook member 1011, so that it is naturally connected to the wire connection device 300 and the wire connection device 300. The connected underground distribution line (L) moves upward, and this is illustrated as shown in FIG. 5A.

As shown in Fig. 7A, when the lift platform 920 is elevated to the highest point, the operator operates the second lift mechanism 1000 by operating a remote controller (not shown), which is carried in more detail. It is as follows.

When an operator operates a remote controller (not shown) and outputs an operation signal wirelessly, the winch 1020 is operated by the output signal to wind the rope 1010, and the rope 1010 is wound. Accordingly, the wire connection device 300 connected via the hook member 1011 is elevated (up and down), and as the wire connection device 300 is elevated, the underground power distribution line electrically connected through the wire connector 300 as a medium. (L) is also elevated together and finally exposed to the outside through the entrance part 112 of the receiving container 100, which is illustrated as shown in FIG. 5B.

At this time, when the underground distribution line L rises together via the wire connection mechanism 300, the underground distribution line L is unwound from the underground distribution line take-up mechanism 500, and the underground distribution line L is a receiving part ( The guide roller 600 is rolled in place so as not to touch the edge at the boundary between the 111 and the entrance 112 and guides the underground distribution line L.

Then, in the reverse order of the above method, the wire connection device 300 and the underground power distribution line L are lowered into the interior of the receiving container 100 so that the wire connection device 300 is accommodated in the tray unit 113.

When the wire connection device 300 is lowered, the underground power distribution line take-up device 500 winds up the underground power distribution line L.

Meanwhile, when infiltrating water flows into the container 100, the water level sensor 700 measures the water level in real time and transmits a detection signal (measured value) to the control unit 800, and the control unit 800 detects the water level. The sensing signal (measured value) received from the sensor 700 is compared with a preset value.

At this time, when it is determined that the measured value has reached the preset value, the control unit 800 immediately transmits the operation signal to the winch 720 of the second lift mechanism 1000 and simultaneously outputs an emergency signal to the transmission unit 1100. , The winch 720 receives an operation signal and winds a rope 710 interconnected with the wire connection device 300 via a hook member 1011 to provide a wire connection device 300 to which the underground distribution line L is electrically connected. It is raised, and the transmission unit 1100 outputs the received emergency signal to the outside.

In addition, as the emergency signal output from the transmitter 1100 wirelessly transmits the emergency signal to the central control room (not shown in detail) where the worker resides, the worker intuitively senses the current state through the received emergency signal. As it can be recognized, it is possible to quickly follow up.

On the other hand, even in the state in which the wire connection device 300 is elevated as described above, the control unit 800 continuously receives a detection signal (measured value) from the water level detection sensor 700, and at this time, it is transmitted from the water level detection sensor 700. When the received detection signal (measured value) and the preset value are compared with each other and it is determined that it is less than the preset value, the operation signal is immediately transmitted to the winch 720 of the second lift mechanism 1000, and the winch 720 is The tray part 113 by receiving the operation signal and lowering the wire connection device 300 to which the underground power distribution line L is electrically connected by loosening the rope 710 interconnected with the wire connection device 300 via the hook member 1011. ).

In this way, it is possible to safely protect the connection part of the underground distribution line L from an accident such as an electric short circuit by preventing the underground distribution line L and the infiltrating water interconnected via the wire connection device 300 from contacting each other.

According to this embodiment, when a tensile force is applied to the underground distribution line L, the underground distribution line take-up mechanism 500 is moved in the pulled direction, and when the tensile force is released, the underground distribution line take-up mechanism 500 by the tension receiving mechanism 400 As is returned to its original position, since it is possible to minimize the application of tensile force to the connection part of the underground power distribution line (L) interconnected via the wire connection device 300, it is possible to fundamentally solve the short circuit problem of the connection part. Accordingly, there is an advantage of maintaining a stable connection.

In addition, when infiltrating water flows into the reservoir 100 buried in the ground, the water level sensor 700 detects it and outputs a detection signal to the control unit, and the control unit receiving the detection signal is the second lift mechanism 1000. And by controlling the operation of the transmission unit 1100, the connection part of the underground distribution line L and the infiltrating water are lifted so that they do not come into contact with each other, and an emergency signal is output to the central control room so that rapid follow-up measures can be taken. There is an advantage of being able to safely protect the distribution line (L).

In addition, since the operator can easily withdraw the wire connection device 300 connected to the underground power distribution line (L) to the outside without entering the container 100 to perform maintenance work, the convenience of work can be greatly improved. There is this.

Although the present invention has been described in detail only with respect to the described specific embodiments, it is natural for those skilled in the art that various modifications and modifications can be made within the scope of the technical idea of the present invention, and it is natural that such modifications and modifications belong to the appended claims.
