Technical Field

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

[0002] Traditional optical cables usually do not have special rodent-proof structures. When laid in areas with serious rodent infestation, the optical cables are easily bitten off. If all of them are replaced with rodent-proof optical cables, the overall cost will be high. 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 comprises an optical cable body and a rat-repellent strip installed on an outer side wall of the optical cable body, wherein the rat-repellent strip comprises: A strip-shaped body, an installation cavity is formed inside the strip-shaped body, a foam material is provided in the installation cavity, a rat repellent agent is filled in the foam material, two ends of the strip-shaped body are adhered to each other to achieve sealing, the strip-shaped body has a first outer wall and a second outer wall, after the rat repellent strip is installed on the optical cable body, the second outer wall faces away from the optical cable body, and a groove is provided on the second outer side wall, and the bottom wall of the groove is adjacent to the installation cavity; The double-sided adhesive layer has one side for sticking on the first outer wall and the other side for sticking on the outer side wall of the optical cable body.

[0005] The present application can set rat repellent strips in areas with serious rat infestation or needing rat prevention as needed, and can be set flexibly without the need for the entire section of the optical cable body to adopt an armored structure, which can effectively reduce costs. In addition, the design of the groove can reduce the wall thickness of the installation cavity, making it easier for the rat repellent agent to evaporate slowly.

[0006] In one embodiment of the present invention, the bottom wall of the groove has micro holes, and the second side wall of the strip body has a protective film.

[0007] In actual use, when or after the optical cable body is laid, the protective film is torn off so that the rodent repellent in the installation cavity can be released outward through the micropores.

[0008] The microporous design facilitates the release of the rodent repellent. The protective film prevents the rodent repellent from being released when the rodent repellent strip is not laid on the optical cable body.

[0009] In one embodiment of the present invention, a fluid replenishment mechanism is further included, and the fluid replenishment mechanism includes: A rehydration bucket with rat repellent inside; A hollow self-tapping fastener is used to cooperate with the groove and is fixed to the side wall of the groove by rotation, and the end of the self-tapping fastener can pierce the bottom wall of the groove and extend into the installation cavity; A liquid replenishing tube, one end of which is connected to the automatic fastener, and the other end of which is connected to the liquid replenishing barrel; A self-priming rope is arranged in the liquid replenishing tube, one end of the self-priming rope passes through the self-tapping fastener and is located in the installation cavity, and the other end is located at the bottom of the liquid replenishing barrel.

[0010] The cooperation of the self-tapping fasteners and the grooves can realize the rapid installation of the liquid replenishing mechanism, and the mouse repellent agent in the liquid replenishing barrel can be replenished into the installation cavity through the self-priming rope, which effectively increases the action time of the mouse repellent strip.

[0011] In actual use, a liquid level sensor and a wireless communication module can be set in the liquid replenishment barrel. When the value measured by the liquid level sensor is lower than the threshold, the wireless communication module transmits a signal to the server to inform the maintenance party that the liquid replenishment barrel can be replenished.

After the rat-repelling strip passes around the support wheel, the release paper is separated from the double-sided adhesive layer; The heating cutting mechanism cooperates with the supporting wheel to cut the rat-repelling strip and make the strip body adhere and seal at the cut position.

[0015] The heating and cutting mechanism cannot cut the rat-repelling strip, and because of the heating function, the outer side walls of the strip body can be pressed against each other during cutting, and can be adhered and sealed under heating conditions.

[0016] In one embodiment of the present invention, the cutting and sealing mechanism comprises: A cutting knife having a heating element therein, the cutting knife being located directly above the supporting wheel; A telescopic element, a movable rod of the telescopic element is fixed to the cutting knife, and the telescopic element is used to drive the cutting knife to approach and move away from the supporting wheel.
