Description

CABLE PROTECTING DUCT FORMED BY COMBINING SUB-CABLE PROTECTING DUCTS HAVING THE SAME STRUCTURE}

The present invention relates to cable sheaths, in particular submarine cable sheaths, and more particularly to cable sheaths that improve work efficiency by using sub-sheaths of the same structure.

Cable sheaths, for example submarine cable sheaths, mean tubes that protect cables installed on the seabed.

In general, the cable sheath consists of two sub cable sheaths, and the cable sheath is formed by fastening the sub cable sheaths using a plurality of bolts or the like. Here, the sub cable sheaths have different structures, and thus, manufacturing costs are increased and joining operations are not easy, such as using different casting molds.

In submarine cable construction, for example, the length of the cable is significant and a large number of cable sheaths must be connected in series. To this end, the sub cable sheaths having different structures are separately disposed on the seabed, and then the sub cable sheaths are combined to form cable sheaths, and the cable sheaths are continuously connected.

In this process, since the sub-cable protection tubes must be separated and arranged and combined, the sub-cable protection tubes have to be found and combined, and thus, the cable construction time can be delayed due to the inconvenient coupling operation.

The combination of the present invention is easy to provide a cable sheath that can reduce the working time.

In order to achieve the object as described above, the cable protection tube according to an embodiment of the present invention is the first sub body, the first sub protection tube insertion portion formed in one end of the first sub body and the other of the first sub body A first sub cable protective tube having a first sub protection tube accommodation portion formed at an end, a first coupling protrusion formed on an outer surface of the first sub body, and a first coupling accommodation portion formed on an outer surface of the first sub body; And a second sub body, a second sub protection tube insertion part formed at one end of the second sub body, and a second sub protection tube accommodation part formed at the other end of the second sub body, and formed on an outer surface of the second sub body. And a second sub cable protective tube having a second coupling protrusion and a second coupling receiving portion formed on an outer surface of the second sub body. Here, when the first sub cable protective tube and the second sub cable protective tube is coupled, the first coupling protrusion is received by the second coupling receiving portion, and the second coupling protrusion is received by the first coupling receiving portion, The first sub protection tube insert and the second sub protection tube insert are combined to form a protection tube insert, and at least one of the coupling protrusions is formed to be inclined in the longitudinal direction of the cable protection tube, and the width of the first sub protection tube insert is Is smaller than the height, and the width of the second sub protection tube insert is smaller than the height.

Since the sub cable sheaths used in the cable sheath according to the present invention have the same structure, the manufacturing cost may be reduced and the operation may be convenient as only one casting mold is required.

In addition, since the sub protection tubes can be combined by a simple operation of inserting the protrusions of the sub cable protection tubes into the corresponding receiving portions, the coupling can be considerably easy and the working time can be considerably shortened.

In particular, since the coupling protrusions of the cable sheath are formed to be inclined at a predetermined angle, and the width of the sub sheath receivers is smaller than the height, there is no movement of a specific cable sheath when connecting the cable sheaths, so that the connection work can be made quickly. have. As a result, the time and manpower for connecting the cable sheaths can be significantly reduced.

In addition, since the protective tube insert of one cable protective tube hardly moves within the protective tube housing of another cable protective tube, mud or the like may not accumulate in the protective tube housing.

Moreover, when the cable sheaths are combined and installed on the sea floor, only the cable sheaths of the design are needed since the sheath insert of one cable sheath hardly moves within the sheath receiving part of the other cable sheath. As a result, the installation cost of the cable sheaths can be reduced.

Hereinafter, the process of connecting the cable sheaths of the present embodiment will be described.

3 is a cross-sectional view illustrating a connection structure of cable protection tubes according to an embodiment of the present invention, and FIGS. 4 to 6 are views illustrating a connection process of cable protection tubes according to an embodiment of the present invention.

Referring to FIG. 3, a plurality of cable protection tubes 300 and 302 having the structure of FIG. 1 may be prepared, and the cable protection tubes 300 and 302 may be sequentially coupled.

In detail, the second cable sheath 302 in a coupled state as shown in FIG. 4 is seated on the second sub sheath receiver 132a of the first cable sheath 300. In this case, since the size of the sub protection tube insertion part 204b of the 2nd cable protection tube 302 is smaller than the size of the sub protection tube accommodation part 202a of the 1st cable protection tube 300, the sub protection tube insertion part 204b has been made. It is easily seated on the second sub protection tube accommodating portion 132a.

Subsequently, as shown in FIG. 5, the user may connect the first sub-protection tube receiving portion 112a of the first cable protection tube 300 to the second sub-protection tube receiving portion 132a so as to connect the first sub- cable protection tube 100a. The first sub protection tube accommodating portion 112a is coupled to the second sub protection tube accommodating portion 132a in a state of being inclined by a predetermined angle. In this case, since the second engagement protrusion 136b extending from the second sub-protective tube accommodating portion 132a is inclined, the first engagement accommodating portion 118a naturally receives the second engagement protrusion 136b. can do. That is, the first sub cable protective tube 100a of the first cable protective tube 130 may be naturally coupled to the second sub cable protective tube 102a.

In particular, since the width of the protective tube receiving portion 204b of the second cable protective tube 132 is smaller than the height, the first sub protective tube receiving portion 112a of the first cable protective tube 130 is coupled as shown in FIG. 5. Is not hindered by the sheath receptacle 204b of the second cable sheath 132. As a result, the first sub-cable protection tube 100a is placed in a state where the sub-protection tube insertion portion 204b of the second cable protection tube 132 is seated on the second sub-cable protection tube 102a of the first cable protection tube 130. It can be naturally coupled to the two sub cable sheath 102a.

Subsequently, when the engagement protrusion 116a and the engagement receiving portion 118a of the first sub cable protection tube 100a are engaged with the engagement receiving portion 138a and the engagement protrusion 136b of the second sub cable protection tube 102a, The first sub cable sheath 100a is laid down in parallel with the ground as shown in FIG. 6.

Next, the cable sheaths 100a and 102a are coupled using the bolt 142.

In summary, the protrusions 116 and 136 of the cable sheath of the present invention are formed to be inclined at a predetermined angle, and the width of the sub sheath receiving portions 114 and 134 is smaller than the height to form the sheath inserting portion 204 of the other cable sheath. The sub cable sheaths 100 and 102 are easily coupled in the received condition.

As a whole, the plurality of cable sheaths are sequentially connected in such a way that the sheath insert of the other cable sheath is inserted into the sheath receiving portion of one cable sheath. In this structure, it is possible to fix by bolting only to the flanges of the cable guard tube located at the end without bolting to the cable guard bars located in the middle.

According to one embodiment of the present invention, as shown in FIG. 3, the protective tube inserting portion 204b of the second cable protective tube 302 is inserted into the protective tube receiving portion 202a of the first cable protective tube 300 in close contact. The portion 204 is inserted into the protective tube receiving portion 202a. If the protective tube inserting portion 204b of the second cable protective tube 302 is inserted without being in close contact with the protective tube receiving portion 202a of the first cable protective tube 300, The two cable sheath 302 may be separated from the first cable sheath 300.

Referring to FIG. 3 again, the protective tube inserting portion 204b of the second cable protective tube 302 is inserted to the inner deep portion of the protective tube receiving portion 202a of the first cable protective tube 300. Therefore, when the cable sheaths 300 and 302 are installed on the seabed while being connected, the sheath inserting portion 204b of the second cable sheath 302 is inside the sheath tube receiving portion 202a of the first cable sheath 300. Hardly moving. As a result, soil or the like may hardly accumulate inside the protective tube receiving portion 202a of the first cable protective tube 300.

Hereinafter, the cable sheath of another structure will be described, and then it will be compared with the cable sheath of the present invention.

7 is an exploded perspective view of the cable protective tube, Figure 8 is a perspective view showing a coupling structure of the cable protective tube of FIG. 9 to 11 are views illustrating a process of connecting the cable protection tubes having the structure of FIG.

As shown in FIGS. 7 and 8, the engagement protrusions 716 and 736 extending from the sub protection tube receiving portions 712 and 732 may be formed parallel to the ground without being inclined unlike the present invention.

Further, the sub guard tube inserts 714 and 734 have the same height and width as shown in FIG. 8 (B), and the sub guard tube inserts 714 and 734 are shown in FIG. 8 (C). Have a small length as As a result, the sheath insert 804b with the sub sheath inserts 714b and 734b of one cable sheath is inserted into the sheath receptacle 802a with the sub sheath receptacles 712a and 732a of the other cable sheath. When the protective tube inserting portion 804b moves a lot in the protective tube receiving portion 802a. As a result, a problem may occur in which mud and the like accumulate inside the protective tube accommodating part 802a.

As mentioned above, the small length of the protective tube insert 804b is to connect the cable protective tubes. Specifically, as shown in FIG. 9, the first cable sheath is seated on the second sub sheath receiving portion 732b of the first cable sheath, and then as shown in FIG. 10. The first sub cable protective tube 700a is inclined by a predetermined angle and attempts to engage with the second sub cable protective tube 702a. In this case, since the inner radius of the first sub-protective tube receiving portion 712b of the second cable protective tube is smaller than the outer radius of the protective tube inserting portion 804a of the first cable protective tube, the first cable in the state of FIG. 10. Only after the protective tube is moved in the direction of the arrow, the first sub protective tube receiving portion 712a of the second cable protective tube may be combined with the second sub protective tube receiving portion 732a. Subsequently, when the first sub protection tube receiving portion 712a is lowered in parallel with the ground, the cable protection tubes are coupled as shown in FIG. 11. However, since the protective tube inserting portion 804b of the first cable protective tube has been moved to the inner side of the protective tube receiving portion 712b of the second cable protective tube, the outer side of the second cable protective tube after the cable protective tubes are combined. Must be pulled in.

Hereinafter, the cable sheath of the present invention and the cable sheath (contrast cable sheath) of FIG. 7 will be compared.

As described above, when the contrast cable protection tubes are coupled, a process of moving the cable protection tubes to be inserted is required to be coupled. As a result, much time and manpower was required for the joining process. Further, since the protective tube inserting portion of one cable protective tube moves within the protective tube receiving portion of the other cable protective tube, mud and the like accumulate in the protective tube receiving portion. Moreover, even if the cable sheaths are manufactured to a certain length, when the cable sheaths are combined and installed on the sea floor, more cable sheaths are required than the design because the sheath insert of one cable sheath moves inside the sheath receiving part of the other cable sheath. .

On the other hand, since the protrusions 116 and 136 of the cable sheath of the present invention are formed to be inclined at a predetermined angle, and the width of the sub protection sheath receiving portions 114 and 134 is smaller than the height, a specific cable sheath is connected when connecting the cable sheaths. There is no moving work, so the connection work can be done quickly. As a result, the time and manpower for connecting the cable sheaths can be significantly reduced. Further, since the protective tube inserting portion of one cable protective tube hardly moves in the protective tube receiving portion of another cable protective tube, mud or the like may not accumulate in the protective tube containing portion. In addition, when the cable sheaths are connected and installed on the sea floor, only the cable sheaths of the design are needed since the sheath insert of one cable sheath hardly moves within the sheath receiving part of the other cable sheath. As a result, the installation cost of the cable sheaths can be reduced.
