Space can be defined.

The cover part 110 is coupled to the upper end of each of the side wall parts 182 to cover the storage space of the storage container 180. In this embodiment, the cover 110 may be a brittle substrate such as a plastic plate.

In this embodiment, the second thickness T2 of the cover portion 110 may be smaller than the first thickness T1 of the bottom portion 181. Therefore, damage to the cover portion 110 may be induced by an external force applied to the cover portion 110 side.

Holes 105 are formed in the cover 110. Each of the holes 105 has a shape penetrating the cover portion 110. Therefore, when the external force applied to the cover 110 is transferred to the powder filling part 130 and the gas filling part 160, the powder filled in the powder filling part 130 and the gas filling the gas filling part 160 are covered. It may be exhausted to the outside of the storage container 180 through the holes 105 of the unit 110. This will be described in more detail with reference to FIG. 4.

The first coupling portions 120 may be provided along the inner circumference of the cover portion 110 to face the top of the side wall portions 182.

The gas filling unit 160 is accommodated inside the storage container 180. In this embodiment, the gas filling unit 160 may be implemented by filling a container made of vinyl or a thin plastic plate with a gas lighter than air, for example, helium gas or hydrogen gas.

In this embodiment, the gas filling units 160 may have a structure divided from each other. More specifically, the gas filling part 160 includes sub gas filling parts 161, and the sub gas filling parts 161 are connected to each other, and two sub gas filling parts adjacent to each other among the sub gas filling parts 161 Between 161, a shield 162 is located. Therefore, even if the two sub gas filling parts 161 are positioned adjacent to each other, the gas is not mixed between the two sub gas filling parts 161 by the shielding part 162.

As described above, when the gas filling part 160 is composed of sub-gas filling parts 161, one hole is generated in the gas filling part 60 so that all the gas charged in the gas filling part 60 is exhausted. Can be prevented. Accordingly, in this embodiment, since the gas is exhausted in correspondence to the portion where the external force is substantially generated in the gas filling unit 60, the operation of the protection device 100 to be described with reference to FIG. 4 can be performed more accurately.

The frame part 150 is seated on the frame support parts 188 and disposed inside the storage container 180, and the frame part 150 is positioned between the gas filling part 160 and the powder filling part 130. Therefore, a space is formed between the gas filling part 160 and the powder filling part 130 by the frame part 150, so that the gas exhausted from the gas filling part 160 can be moved in the space.

In this embodiment, the frame unit 150 includes first frames 151 and second frames 152 connected to the first frames 151. The first frames 151 intersect with the second frames 152.

In this embodiment, the first frames 151 and the second frames 152 may be implemented with thin wood or wires.

According to the above-described structures of the first and second frames 151 and 152, the first and second frames 151 and 152 are connected to each other, but vents 155 are defined between adjacent frames. Therefore, the gas discharged from the gas filling part 160 may be provided to the powder filling part 130 through vents 155.

The powder filling part 130 is accommodated in the storage container 180, and the powder filling part 130 is disposed on the gas filling part 160 with the frame part 150 interposed therebetween. In this embodiment, the powder filling unit 130 may be implemented by filling a container made of vinyl or thin plastic plate with powder 185. Further, the powder 185 may be a powder of various colors, such as a red powder such as a white powder, a blue powder, and a yellow powder. In addition, the powder 185 may be desirably blown by the gas charged in the gas filling unit 160, so that the size of the particles of the powder 185 is small and the weight of the particles of the powder 185 is small.

In this embodiment, the powder filling unit 130 may have a structure divided from each other. More specifically, the powder filling part 130 includes sub powder filling parts 131, and the sub powder filling parts 131 are connected to each other, and two sub powder filling parts adjacent to each other among the sub powder filling parts 131 Between 131, the shield 132 is located. Therefore, even if the two sub powder filling parts 131 are positioned adjacent to each other, the powder 135 is not mixed between the two sub powder filling parts 131 by the shielding part 132.

As described above, when the powder filling part 130 is composed of sub powder filling parts 131, powder may be uniformly distributed over the entire area of the powder filling part 130, and within the powder filling part 130 The powder can be prevented from being placed locally.

4 is a view for explaining the operation of the protection device when an external force is applied to the protection device side.

1 and 4, a protection device 100 that receives an external force 200 from the outside is disclosed. For example, in the state in which the protection device 100 is buried in the underground 10 together with the underground cable 50, an external force 200 may be applied to the protection device 100 side by an excavation operation using an excavator.

In this case, since the protection device 100 in the underground 10 is buried at the top of the underground cable 50, the protection device 100 firstly transmits the external force 200 directly to the underground cable 50. 50 is prevented from being damaged.

In this embodiment, when the external force 200 is applied to the protection device 100, the protection device 100 informs the operator that the excavation position of the underground 10 is close to the underground cable 50. The operation of the protection device 100 related to this is as follows.

When the external force 200 is applied to the protection device 100, the external force 200 is sequentially transmitted to the cover part 110, the powder filling part 130, the frame part 150, and the gas filling part 160. As described above, when the cover 110 is made of a brittle substrate such as a plastic plate, when the external force 200 generated by an object having a large weight such as an excavator contacts the cover 110 The part 110 is broken.

Meanwhile, as described above, each of the container accommodating the powder 135 in the powder filling part 130 and the container accommodating the gas 165 in the gas filling part 160 is made of a vinyl or a thin plastic plate. Since the frames 151 and the second frames 152 are implemented with thin wood or wires, when the external force 200 is transmitted to the powder filling part 130 and the gas filling part 160, the powder filling part 130 ) The container containing the powder 135 and the container containing the gas 165 of the gas filling unit 160 are damaged.

As a result, the gas 165 is discharged from the gas filling unit 160, and the powder 135 is discharged from the powder filling unit 130. In addition, since the gas 165 discharged from the gas filling unit 160 is lighter than air, the gas 165 is provided to the powder 135 side discharged from the powder filling unit 130 through vents 155. Accordingly, the powder 135 is blown upward by the gas 165 so that the powder 135 can be exhausted to the outside of the protection device 100 through holes 105 formed in the cover 110.

In this embodiment, even if the external force 200 acts on the frame part 150, since some space remains between the gas filling part 160 and the powder filling part 130 by the frame part 150, the gas filling part ( A process in which the gas 165 discharged from 160 moves upward may be more easily performed.

In the case where the powder 135 is blown out of the protection device 100 by the gas 165 on the above-described principle, the worker can visually recognize the blowing powder 135, and accordingly, the worker can protect the excavator from the protection device ( 100). Accordingly, the operator can take measures such as stopping the longitudinal excavation work on the ground, and accordingly, the underground cable buried under the protection device 100 can be prevented from being damaged due to the excavation work.
