Further optimizing the measures for preventing the bite of the optical cable has important significance to the normal operation of the optical cable network.
Disclosure of Invention
Aiming at the technical problem that the further optimization of the optical cable bite prevention measures is of great significance to the normal operation of an optical cable network, the invention provides the steel-tape armored ratproof optical cable.
The technical means of the scheme is that the steel-tape armored rat-proof optical cable comprises an armor layer, a sheath and an airbag, wherein the sheath is arranged on the outer side of the armor layer, the airbag is doped in the sheath, the airbag comprises a rat repellent which is a content and an airbag wrapping the rat repellent, the airbag is used for preventing the rat repellent from volatilizing from the airbag to the outside, and the airbag can be punctured by teeth of a rat.
In the prior art, a chemical method is one of important measures for preventing the optical cable from being ratcheted, and the common mode is as follows: the optical cable sheath is added with a rat repellent such as pungent monosodium glutamate. However, in the actual use process, if the sheath is made of polyethylene, the optical cable has a certain rat-proof effect when being used at the beginning, but with the increase of the use time, the rat repellent such as pungent taste essence can volatilize from the polyethylene sheath layer, and the volatilization is faster at higher temperature. In practical application, the optical cable added with the capsaicin sheath is bitten by a mouse in less than half a year after installation.
Different from the prior art, in the scheme, the rodenticide is not directly mixed in the sheath material, but is coated in the form of capsule bodies and exists in the sheath, so that the protection of the capsule on the rodenticide is utilized, when the capsule is punctured by mouse teeth in the process of biting the optical cable by a mouse, the capsule is exposed in an exposed environment to play the purpose of deratization, the loss of the protection effect due to volatilization of the optical cable in the use process can be effectively avoided, the purpose of prolonging the protection time of the rodenticide is achieved, and the optical cable can have the rat-proof function for a long time.
The capsule can be made of butyl rubber, polyvinyl chloride, or biodegradable material such as polylactic acid.
The further technical scheme is as follows:
considering the sheath protective performance required by the optical cable, the introduction of the capsule body has little influence on the performance of the sheath, and the capsule body can well exert the rat repelling performance when a rat bites the capsule body, and the technical scheme is as follows: the number of the capsules is multiple, and the capsules are uniformly distributed in the sheath; the proportion of the capsule body to the sheath is as follows by weight: 2-5: 100; the particle size of the capsule body is 0.3-1 mm.
For after the utricule exposes in the environment, for making the utricule can take place to degrade in the time of relative short to do benefit to the environmental protection, make the rat repelling agent can lose efficacy fast simultaneously, do benefit to the surrounding environment security, set up to: the material of the capsule is biodegradable material.
As a technical scheme which is easy for preparing the capsule body, realizes the mixing of the capsule body in a sheath material and does not generate any pollutant after decomposition, the material of the capsule body is polylactic acid. For the application of the capsule of polylactic acid, the wall thickness of the capsule is set to be 0.1-0.3 mm in consideration of preparation and other problems.
As a concrete implementation mode of the rat repelling agent with small environmental impact, the rat repelling agent is set as follows: the mouse repellent is one or two of capsaicin and cycloheximide.
In order to achieve the purpose of well stimulating the mice, the device is set as follows: the rat repellent consists of pungent monosodium glutamate and cycloheximide; the weight ratio of the capsaicin to the cycloheximide is 1: 2-4. In the scheme, the pungent taste essence can directly stimulate the mice, and the cycloheximide is unstable in an alkaline solution, is rapidly destroyed particularly when p H is more than 8.0, and is stable under neutral and acidic conditions; is stable at room temperature in a dry state and is not influenced by sunlight. When the oral mucosa of the mouse contacts the cycloheximide concentrated solution or the crystal, the oral mucosa of the mouse is strongly stimulated, and the purpose that the mouse does not chew the material is achieved by forming conditioned reflex. The proportion of the spicy essence and the cycloheximide is selected, so that the spicy essence and the cycloheximide can jointly play a role in repelling rats; meanwhile, mouse saliva is matched with an alkaline environment formed by the exposed capsaicin, so that the failure of the cycloheximide is accelerated, and the environmental problem caused by the cycloheximide is avoided.
The cable also comprises a plurality of metal hoops hooped on the armor layer, and the metal hoops are arranged at intervals along the extending direction of the optical cable; the metal hoops are all wrapped in the sheaths. In the prior art, an optical cable including an armor layer is a common physical optical cable protection method, however, in the existing implementation mode: the method is characterized in that a low-strength and thick chromium-plated steel belt is adopted, wherein the steel belt is not corrosion-resistant, after a plastic sheath on the outer layer is bitten by rodents, the steel belt is corroded to leak out of a plastic sleeve in the optical cable, and the rodents can damage optical fibers for communication after biting the sleeve;
a stainless steel band is adopted, although rodents cannot bite through the stainless steel band, after the plastic sheath on the outer layer is bitten, the steel band is separated from the lap joint, and the sleeve pipe without the protection of the steel band is bitten;
the adoption of chromium-plated steel strips and low-carbon steel wires for full-sealed wrapping has the primary disadvantages of heavy optical cable and high laying and installation cost. The optical cable has large size, more material consumption and high cost;
the spiral steel strip armor is adopted, the spiral steel strip needs to be wound on the optical cable, the steel strip needs to rotate around the optical cable, the production efficiency is very low, the cost is high, and gaps are formed among the spiral steel strips, so that water and moisture cannot be prevented from invading the optical cable;

Therefore, in particular, it is preferable to use an armor layer made of a metal material.
In the application, the metal hoop is introduced, which aims to prevent the sheathing layer formed by the stainless steel band from splitting from the overlapping part after the sheathing material is worn after long-term use or is bitten by animals such as mice and the like, and a plurality of stainless steel wires wound outside the stainless steel band at uniform pitches are formed into the metal hoop, and the diameter of the stainless steel wires is not less than 0.3 mm. In specific application, 304 stainless steel or stainless steel with corrosion resistance larger than 304 is adopted as the stainless steel wire and the stainless steel belt.
As a technical scheme for realizing sheath reinforcement through glass fibers and forming physical protection by utilizing the stimulation effect of the glass fibers, the technical scheme is as follows: the sheath is also doped with glass fiber. Meanwhile, in the scheme, the glass fiber is generally used for forming glass fiber armoring in the prior art, the glass fibers are bonded by thermoplastic or thermosetting plastic, the strength of the plastic is not high, rodents such as mice and the like can bite the plastic, and the practical application condition shows that in an area with frequent mouse movement, after one to three months, some optical cable sheaths of the glass fiber armoring are still bitten by the rodents, and the optical cable is seriously damaged. According to the scheme, the glass fiber is doped in the sheath, and the sheath is utilized to form anti-biting protection for the glass fiber.
In the prior art, the application of the glass fiber on the sheath is the prior art, but the common application mode is as follows: glass fiber sets up in the inboard or the outside of sheath, and glass fiber is longer, like this, only after glass fiber is bitten into apart, just can make glass fiber form physical stimulation to the mouse, to this problem, in this scheme: the glass fiber has the length: 0.2-1.5 mm; the proportion of the glass fiber to the sheath is as follows by weight: 7.5: 90-100. In this scheme, through changing present glass fiber into the short-staple of above size for have more glass fiber tip in the sheath, promptly at the in-process that the mouse gnaw and stings naturally, have higher probability promptly and utilize glass fiber stimulation mouse's oral cavity, in order to obtain better protection against rodents effect.
As a technical scheme which is convenient for preparation and is beneficial to distribution uniformity, the method is characterized in that: the glass fiber and the capsule are both doped in the sheath by an extruder. In the specific implementation, firstly, a double-screw extruder is used for preparing the glass fiber reinforced polyethylene, and the glass fiber reinforced polyethylene raw material is prepared by mixing 7.5:10:90 glass fiber, Maleic Anhydride (MAH) and polyethylene in a high-speed mixer and then extruding and granulating the mixture by using the double-screw extruder.
When the optical cable is produced, the pungent odor element, the cycloheximide repellent capsule body and the glass fiber reinforced protective raw material are extruded on the optical cable embossing armor steel belt by a single-screw extruder according to the weight ratio of 2.5: 107.5.
The invention has the following beneficial effects:
different from the prior art, in the scheme, the rodenticide is not directly mixed in the sheath material, but is coated in the form of capsule bodies and exists in the sheath, so that the protection of the capsule on the rodenticide is utilized, when the capsule is punctured by mouse teeth in the process of biting the optical cable by a mouse, the capsule is exposed in an exposed environment to play the purpose of deratization, the loss of the protection effect due to volatilization of the optical cable in the use process can be effectively avoided, the purpose of prolonging the protection time of the rodenticide is achieved, and the optical cable can have the rat-proof function for a long time.
