The body portion 10 includes a case 12 in which the rotating body 20 is installed, a lid portion 14 covering the case 12, a support portion 13 protruding outside the case 12, Or a fixing portion 16 fixed to the fence.

The case 12 is provided with an installation space in which the rotating body 20 is installed, and an opening 12a may be formed at one side thereof. The lid portion 14 is detachably attached to the opening 12a.

The lid portion 14 is provided so as to cover the opening portion 12a of the case 12 and can be detachably installed using a fastening member such as a bolt member. In this way, the case 12 provided with the lid portion 14 can be supported by the fixing portion 16 on the support base 13.

The fixing portion 16 may be formed to protrude from the side surface of the case 12 and may be formed as a latching ring. Hereinafter, the same reference numeral 16 is used for the fixing portion and the latching ring.

The latching ring 16 may be provided on the case 12 so as to protrude in a round shape. To this end, the case 12 may be provided with a fixing hole 15b through which the latching ring 16 is inserted and fixed. Both ends of the latching ring 16 can be fixed to the case 12 by a fastening member (not shown) while being inserted into the fastening hole 15b of the case 12. [

On the other hand, it is also possible for the case 12 to have a protruding portion 15 at a portion between the case 12 and the retaining ring 16. The protrusion 15 has a concave portion 15a formed at a protruded end position so that a part of the support can be stably inserted and fixed without interference between the protrusion 15 and the retaining ring 16. [ In addition, a clip member 17 for fixing the optical cable 11 may be provided in the case 12. [

The case 12 may be provided with a pipe member 18 into which the optical cable 11 is inserted.

The pipe member 18 includes a first pipeline 18a connected to one side of the body 10 and inserted into the optical cable 11 and a second pipeline 18b connected to the other side of the body 10 to pull the optical cable 11 And a second pipeline 18b.

The first pipeline 18a has one end connected to one side of the case 12 and the other end extending to the outside of the case 12. The inside of the first pipeline 18a is inserted into the case 12 through the optical cable 11, . Since the first pipeline 18a is formed of a flexible material that can be bent, the optical cable 11 can be easily inserted into the first pipeline 18a.

The second pipeline 18b may have one end connected to the other side of the case 12 and the other end extended to protrude in the opposite direction in which the first pipeline 18a is installed. The optical cable 11 can be drawn out from the case 12 inside the second pipeline 18b. Accordingly, the optical cable 11 can be installed to pass through the first pipeline 18a, the body part 10, and the second pipeline 18b.

The reason why the optical cable 11 is installed so as to pass through the first pipeline 18a, the case 12 and the second pipeline 18b is that the optical cable 11 is stretched inside the case 12 So that it can be easily confirmed.

That is, when the optical network bottom sensing apparatus 100 of the present embodiment is lifted in the course of intruders passing through the security fence installed by the support member 13, the optical fiber cable 11 is checked for being pulled. To this end, the rotating body 20 and the pressing portion 40 may be installed inside the case 12. [ This will be described in detail below.

FIG. 4 is a principal perspective view schematically showing a state before the operation of the optical network bottom sensing apparatus according to an embodiment of the present invention, and FIG. 5 is a main perspective view schematically illustrating an operation state of the optical network bottom sensing apparatus of FIG.

4 and 5, the rotating body 20 includes a rotating plate 21 rotatably installed in the body 10, a rotating plate 21 protruding from the rotating plate 21 to rotate the optical cable 11, And a first latching protrusion 23 to which a part of the latching protrusion 23 is caught.

The rotation plate 21 can be rotatably installed on the inner wall surface of the case 12. [ The rotating operation of the rotating plate 21 can be rotated when a tensile force is applied to the optical cable 11. [ The first latching protrusion 23 may protrude from the rotary plate 21 so that the tensile force of the optical cable 11 acts on the rotary plate 21. [

The first latching protrusion 23 protrudes from the surface of the rotary plate 21 and may protrude in a plurality of directions. The first latching protrusions 23 are illustratively described as projecting in pairs in a spaced apart relationship in this embodiment.

In this state, the first latching protrusions 23 protrude from the rotary plate 21 in a state of being spaced apart from each other. When the optical cable 11 is inserted into the body 10, As you can see, you can wrap it up.

That is, since the optical cable 11 is staggered between one side surface and the other side surface of the first latching projections 23, when the tensile force is applied to the optical cable 11, rotation of the rotation plate 21 Operation can be performed.

On the other hand, the rotation plate 21 may be provided with an angle adjusting unit 30 for limiting the rotation angle.

The angle adjusting portion 30 can be applied to a spring member having one end connected to the inner wall surface of the case 12 inside the body 10 and the other end connected to the rotary plate 21. [ Hereinafter, the angle adjusting portion and the spring member use the same reference numeral 30.

When the intruder lifts the optical network or lifts the optical network lower sensing apparatus 100 to generate a tensile force on the optical cable 11 connected to the optical network and the rotation plate 21 is rotated to one side, It is possible to restrict rotation. Also, the spring member 30 can cause the rotary plate 21 to rotate in the initial position when the tensile force applied to the optical cable 11 is released.

On the other hand, a pressing portion 40 may be provided on a side surface of the rotary plate 21. [

The pressing portion 40 includes a latching plate 41 protruding from the edge of the rotary plate 21 and a second latching protrusion 43 protruding from the rotary plate 21 at a position spaced apart from the rotary plate 21 can do.

The locking plate 41 may protrude from the rotation plate 21 so that the optical cable 11 having passed through the first locking protrusion 23 is positioned in contact with the side surface. That is, the optical cable 11 may extend so as to be contacted along the side surface of the latching plate 41 after passing through the first latching protrusion 23 in a staggered bent state.

The optical cable 11 is extended in a state of being in contact with the latching plate 41 and can be bent at the edge side of the latching plate 41 and hooked on the second latching protrusion 43. [

The second locking protrusion 43 may protrude from the rotating plate 21 at a plurality of positions on the inner wall surface of the case 12. [ Accordingly, the optical cable 11 can pass through the first latching protrusion 23 and the second latching protrusion 43 in a staggered state while being staggered in the rotating body 20.

The second locking protrusion 43 protrudes from the case 12 in a spaced relationship with the first locking protrusion 23 so that the optical cable 11 passing through the inside of the body 10 The first and second latching protrusions 23 and 43 can be staggered.

5, when the optical cable 11 is pulled in the case 12 of the body portion 10, the optical cable 11 is caught by the latching action of the second latching projection 43, And can be bent at the edge portion (A) of the plate (41).

Accordingly, when the intruder intrudes the security fence unauthorizedly, the optical cable 11 connected to the optical network is bent and damaged inside the body 10 when the optical network bottom sensing apparatus 100 or the optical network is lifted up .

Accordingly, it is possible to effectively confirm that the intruder passes through the lower portion of the security fence, and it is possible to improve the performance of detecting the intruder intrusion.

The operation of the optical network bottom sensing apparatus of the present embodiment having the above-described configuration will be described in detail below.

First, when an intruder breaks or lifts the pipe of the security fence, the optical cable 11 connected to the optical network is pulled in the inside of the body part 10. [

Then, the rotating body 20 is rotated in one direction as shown in Fig. 5 by the action of the tensile force of the optical cable 11 inside the body part 10. [ Here, the optical cable 11 may be pressed or bent or damaged at the edge portion of the latching plate 41 protruding from the rotating body 20.

Accordingly, it is possible to confirm that the intruder penetrates through the security fence by confirming the damage or bending state of the optical cable 11.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, Of course.
