Description

Technical Field

[0001] The present invention relates to the field of optical communications, and in particular to an optical cable. Background Art

[0002] When it snows in cold regions, the snow will accumulate on the overhead optical cables. When the weight of the snow exceeds the limit of the optical cables, the optical cables will be damaged or even broken. Summary of the invention

[0003] In view of the above problems, the present invention provides an optical cable.

[0004] The technical solution adopted by the present invention is as follows: An optical cable, comprising an optical cable body, a connecting wire, a snow removal plate and a snow removal mechanism: The outer side wall of the optical cable body has at least one strip groove, and the strip groove is arranged along the length direction of the optical cable body; The connecting wire is embedded in the strip groove, there are a plurality of snow removal boards, each snow removal board is distributed at intervals, and the snow removal board is located outside the optical cable body and connected to the connecting wire through a connecting portion; The snow removal mechanism cooperates with the connecting wire to drive the connecting wire and the snow removal plate to reciprocate.

[0005] When there is snow accumulation, the snow will accumulate on the optical cable body and the snow removal board. By driving the connecting wire to move (coming out of the strip groove and entering the strip groove again), the snow removal board can move relative to the optical cable body, thereby destroying the state of the snow accumulation and causing the snow to quickly fall off the optical cable body and the snow removal board.

[0006] In actual use, the optical cable body is laid overhead on a supporting column, and the snow removal mechanism is installed on the supporting column and cooperates with the connecting wire.

[0007] In one embodiment of the present invention, the connecting wire cooperates with the snow removal mechanism after being cut, and the snow removal mechanism includes: A mounting seat, through which the optical cable body passes and is restricted; A slide rail, fixed on the mounting seat; A movable block, slidably disposed on the slide rail; A pressing block is detachably fixed on the movable block, and the cut connecting wire is located between the movable block and the pressing block, and is fixed relative to the movable block and the pressing block; The telescopic element is mounted on the mounting seat and connected to the pressing block or the movable block, and is used to drive the movable block and the pressing block to move back and forth.

[0008] The working principle of the snow removal mechanism is that the telescopic element works, driving the movable block, the pressure block, the connecting wire, and the snow removal plate to move back and forth, so that the accumulated snow quickly falls off the optical cable body and the snow removal plate.

[0009] In actual use, the movable block and the pressing block can be detachably connected by fasteners.

[0010] In actual application, the telescopic element can be an electric push rod.

[0011] In actual use, the mounting seat is fixed on the supporting column. The mounting seat is composed of two parts, an upper part and an lower part. The optical cable body is clamped by the upper and lower parts of the mounting seat.

[0012] In one embodiment of the present invention, the movable block has an initial working position. In the initial working position, the movable block abuts against an outer side wall of the optical cable body.

[0013] In one embodiment of the present invention, the movable block and the pressing block are both arc-shaped.

[0014] In one embodiment of the present invention, the movable block has a limiting groove on one side away from the optical cable body, and a limiting knot is set at the end of the connecting wire after being cut. The connecting wire after being cut bypasses the limiting groove of the movable block in the opposite direction and passes through the movable block. The movable block, the pressing block and the limiting knot cooperate with each other to limit the connecting wire after being cut.

[0015] This arrangement can ensure that the cut connecting wire is reliably connected to the snow removal mechanism without slipping, so that the telescopic element can drive the movable block, the pressure block, the connecting wire and the snow removal plate to move back and forth when working.

[0016] In actual use, the limit knot can be formed by tying a knot in the connecting wire, or it can be installed separately on the cut connecting wire.

[0017] In one embodiment of the present invention, the outer side wall of the optical cable body further has an installation groove, and the strip groove passes through the installation groove; The connecting portion of the snow removal plate is embedded in the installation groove, and the connecting portion has a connecting structure connected to the connecting wire.

[0018] In one embodiment of the present invention, the connection structure is a slot.

[0019] This arrangement facilitates reliable connection between the snow removal plate and the connecting wire.

[0020] In one embodiment of the present invention, the main body of the snow removal board is an arc-shaped structure adapted to the outer side wall of the optical cable body.

[0021] In one embodiment of the present invention, there are a plurality of the strip-shaped grooves, and the plurality of strip-shaped grooves are evenly distributed around the axis of the optical cable body.

[0022] In one embodiment of the present invention, there are two slide rails, and two ends of the movable block are respectively slidably matched with the two slide rails.

[0023] The beneficial effect of the present invention is that when there is snow accumulation, the snow will accumulate on the optical cable body and the snow removal board. By driving the connecting wire to move (coming out of the strip groove and entering the strip groove again), the snow removal board can be moved relative to the optical cable body, thereby destroying the state of the snow accumulation and causing the snow to quickly fall from the optical cable body and the snow removal board.

[0029] The present invention is described in detail below in conjunction with the accompanying drawings.

[0030] like Figures 1 to 5 As shown, an optical cable includes an optical cable body 1, a connecting wire 2, a snow removal plate 3 and a snow removal mechanism 4: The outer side wall of the optical cable body 1 has at least one strip groove 11, and the strip groove 11 is arranged along the length direction of the optical cable body 1; The connecting wire 2 is embedded in the strip groove 11, and there are multiple snow removal boards 3, each of which is distributed at intervals. The snow removal boards 3 are located outside the optical cable body 1 and are connected to the connecting wire 2 through the connecting portion 31; The snow removal mechanism 4 cooperates with the connecting wire 2 to drive the connecting wire 2 and the snow removal plate 3 to reciprocate.

[0031] When there is snow accumulation, the snow will accumulate on the optical cable body 1 and the snow removal board 3. By driving the connecting wire 2 to move (coming out of the strip groove 11 and entering the strip groove 11), the snow removal board 3 can be moved relative to the optical cable body 1, thereby destroying the state of the snow accumulation and causing the snow to quickly fall from the optical cable body 1 and the snow removal board 3.

[0032] In actual use, the optical cable body 1 is laid overhead on a supporting column, and the snow removal mechanism 4 is installed on the supporting column and cooperates with the connecting wire 2.
