Description

Technical Field

[0001] This utility model belongs to the field of power cable technology, and in particular relates to a power cable with an insect-proof structure. Background Technology

[0002] As a key carrier of power transmission, power cables are widely laid in various environments, including outdoor, underground, and complex locations such as damp areas. However, in these environments, power cables often face the threat of pests. For example, termites, bark beetles, and other insects will gnaw on the outer structure of the cable. Once the outer layer is damaged, the inner core layer will be exposed, leading to serious problems such as short circuits and leakage. This not only affects the normal transmission of power but may also bring safety hazards, such as causing fires. Cable joints are an important part of cable lines, but due to their structural characteristics, they are often weak points in pest prevention.

[0003] Existing cable joints typically rely on ordinary rubber or plastic sealing materials to prevent the intrusion of moisture and dust. However, this sealing method is ineffective against insects. Insects can enter through gaps in the joint and gnaw on the cable's insulation or conductor, causing short circuits, open circuits, and other faults, seriously affecting the safe and stable operation of the power system. Therefore, we provide a power cable with an insect-resistant structure to solve the aforementioned problems. Utility Model Content

[0004] The purpose of this utility model is to provide a power cable with an insect-proof structure. By combining the protective layer and the insect-proof components, it solves the problem that cable joints in the prior art generally rely only on ordinary rubber or plastic sealing materials for sealing, which has a poor protective effect against insects.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0006] This utility model relates to a power cable with an insect-proof structure, comprising an outer sheath, a protective layer fixedly connected to the inner wall of the outer sheath, a core layer fixedly connected to the inner wall of the protective layer, an insect-proof component fitted on one side of the outer sheath, the insect-proof component including a protective sleeve, an inner lining layer fixedly connected to the inner wall of the protective sleeve, a spacer between the protective sleeve and the inner lining layer, the cavity formed between the spacer is filled with an insect-proof agent, a serrated strip fixedly connected to the surface of the protective sleeve, a sealing sleeve provided on one side of the protective sleeve, the sealing sleeve being fitted onto the surface of the outer sheath, and the spacer between the protective sleeve and the inner lining layer... These dividers separate the space between the protective cover and the inner lining into multiple independent small areas. Each small area, i.e., the cavity formed between the dividers, is evenly filled with an insect repellent. The insect repellent is a natural plant extract, such as peppermint oil. While ensuring the insect repellent effect, it minimizes the impact on the environment. The dividers are made of plastic material with a certain degree of elasticity and toughness. Their function is not only to separate the space, but also to buffer external pressure to a certain extent, preventing the insect repellent from leaking due to external pressure on the protective cover and the inner lining. The presence of serrated strips changes the surface structure of the protective cover, making it difficult for insects to find a stable foothold, thereby increasing the difficulty for insects to climb.

[0007] The present invention is further configured such that a sealing strip is fixedly connected to the inner wall of the sealing sleeve, one side of the sealing strip contacts the outer sheath, and the sealing sleeve is tightly fitted onto the surface of the outer sheath. Through the cooperation of the sealing strip, a tight fit with the surface of the outer sheath is ensured. On the one hand, this can prevent external moisture, dust and other impurities from entering the insect-repellent component, avoiding adverse effects such as dilution or contamination of the insect repellent, and ensuring the stability and effectiveness of the insect repellent. On the other hand, the sealing sleeve can further enhance the tightness of the connection between the protective sleeve and the outer sheath, preventing the protective sleeve from shifting or falling off during cable laying or use, and ensuring that the protective sleeve is always in an effective protective position.

[0008] The present invention is further configured such that the protective layer includes a thin film isolation layer, a polyethylene agent layer is fixedly connected to the surface of the thin film isolation layer, and a diatomaceous earth adsorption layer is fixedly connected to the surface of the polyethylene agent layer. The thin film isolation layer is attached to the inner wall of the outer sheath, providing a stable adhesion base for the subsequent polyethylene agent layer, while effectively blocking the intrusion of external moisture and humidity, preventing them from damaging the polyethylene agent layer. The polyethylene agent layer continuously and stably releases its pesticide over a long period of time, effectively repelling insects near the cable. The diatomaceous earth adsorption layer covers the surface of the polyethylene agent layer. Utilizing the unique porous structure of diatomaceous earth, it has a strong adsorption capacity for the insect repellent volatilized from the polyethylene agent layer, extending the release time of the pesticide.

[0009] The present invention is further configured such that the core layer includes a conductor core, and an insulating layer is fixedly connected to the surface of the conductor core. The insulating layer can effectively isolate the electrical connection between the conductor cores and between the conductor cores and the outside world, ensuring the safety of power transmission.

[0010] The present invention is further configured such that the number of conductor cores is five, and the spacing between the conductor cores is equal. The copper conductors in the conductor cores are formed by stranding. The equal spacing between the five conductor cores helps to reduce electromagnetic interference between the cores and improve the transmission efficiency and stability of the cable.

[0011] The present invention is further configured such that a filling layer is provided on one side of the protective layer, the filling layer fills the gap between the core layer and the protective layer, and the filling layer is provided between the core layer and the protective layer to ensure the protective performance of the internal core.

[0012] The present invention has the following beneficial effects.

[0013] 1. This utility model fills the cavity between the protective sleeve and the inner lining layer in the insect-proof component with insect-repellent agent, which can continuously release insect-repellent ingredients and effectively repel insects approaching the cable. At the same time, the serrated strips on the surface of the protective sleeve change the physical structure of the cable surface, making it difficult for insects to climb and attach, further enhancing the insect-proof effect. The polyethylene agent layer in the protective layer contains insect-repellent ingredients and can provide insect-proof protection from the inner layer, while the diatomaceous earth adsorption layer can adsorb the agent volatilized from the polyethylene agent layer, prolonging the agent's action time and enhancing the durability of insect-proofing. The thin film isolation layer can prevent excessive volatilization of the agent and ensure the stability and long-term effectiveness of the protective layer.

[0014] 2. This utility model uses a sealing strip on the inner wall of the sealing sleeve to make close contact with the outer sheath, which not only enhances the sealing between the insect-proof component and the outer sheath, preventing external moisture and dust from entering and protecting the internal structure from corrosion, but also helps to prevent leakage of insect-proof agents and ensure the stability of the insect-proof effect. The filling layer fills the gap between the core layer and the protective layer, ensuring the compactness of the internal structure of the cable and improving the overall mechanical properties and stability of the cable.

Detailed Implementation

[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Please see Figure 1-5 This utility model is a power cable with an insect-proof structure, including an outer sheath 1, a protective layer 2 fixedly connected to the inner wall of the outer sheath 1, a wire core layer 3 fixedly connected to the inner wall of the protective layer 2, an insect-proof component 4 sleeved on one side of the surface of the outer sheath 1, the insect-proof component 4 including a protective sleeve 401, an inner lining layer 402 fixedly connected to the inner wall of the protective sleeve 401, a spacer 403 provided between the protective sleeve 401 and the inner lining layer 402, the cavity formed between the spacer 403 is filled with an insect-proof agent, a serrated strip 404 fixedly connected to the surface of the protective sleeve 401, and a sealing sleeve 405 provided on one side of the protective sleeve 401, the sealing sleeve 405 being sleeved on the surface of the outer sheath 1.

[0025] Specifically: the spacers 403 between the protective cover 401 and the inner lining 402 divide the space between the protective cover 401 and the inner lining 402 into multiple independent small areas. Each small area, i.e., the cavity formed between the spacers 403, is uniformly filled with an insect repellent. The insect repellent is a natural plant extract, such as peppermint oil. While ensuring the insect repellent effect, the impact on the environment is minimized. The spacers 403 are made of plastic material with a certain degree of elasticity and toughness. Their function is not only to separate the space, but also to buffer external pressure to a certain extent, preventing the insect repellent from leaking due to external pressure on the protective cover 401 and the inner lining 402. The presence of the serrated strips 404 changes the surface structure of the protective cover 401, making it difficult for insects to find a stable foothold, thereby increasing the difficulty for insects to climb.

[0026] Example 2

[0027] Please see Figure 1-5 Based on Embodiment 1, a sealing strip 5 is fixedly connected to the inner wall of the sealing sleeve 405. One side of the sealing strip 5 is in contact with the outer sheath 1. The protective layer 2 includes a thin film isolation layer 201. A polyethylene agent layer 202 is fixedly connected to the surface of the thin film isolation layer 201. A diatomaceous earth adsorption layer 203 is fixedly connected to the surface of the polyethylene agent layer 202. The core layer 3 includes a conductor core 301. An insulation layer 302 is fixedly connected to the surface of the conductor core 301. There are five conductor cores 301, and the spacing between the conductor cores 301 is equal. The copper conductors in the conductor cores 301 are formed by stranding. A filling layer is provided on one side of the protective layer 2. The filling layer fills the gap between the core layer 3 and the protective layer 2.

[0028] Specifically: The sealing sleeve 405 is tightly fitted onto the surface of the outer sheath 1, and through the cooperation of the sealing strip 5, ensures a tight fit with the surface of the outer sheath 1. On the one hand, it prevents external moisture, dust, and other impurities from entering the insect-repellent component 4, avoiding adverse effects such as dilution or contamination of the insect repellent agent, and ensuring the stability and effectiveness of the insect repellent agent. On the other hand, the sealing sleeve 405 further enhances the tightness of the connection between the protective sleeve 401 and the outer sheath 1, preventing the protective sleeve 401 from shifting or falling off during cable laying or use, ensuring that the protective sleeve 401 is always in an effective protective position. The thin film isolation layer 201 is attached to the inner wall of the outer sheath 1, providing a stable adhesion base for the subsequent polyethylene agent layer 202, while effectively blocking the intrusion of external moisture and humidity, preventing them from damaging the polyethylene. The polyethylene agent layer 202 causes damage, and the polyethylene agent layer 202 continuously and stably releases the insect repellent for a long time, effectively repelling insects near the cable. The diatomaceous earth adsorption layer 203 covers the surface of the polyethylene agent layer 202. Utilizing the unique porous structure of diatomaceous earth, it has a strong adsorption capacity for the insect repellent volatilized from the polyethylene agent layer 202, prolonging the release time of the agent. The insulation layer 302 can effectively isolate the electrical connection between the conductor cores 301 and between the conductor cores 301 and the outside world, ensuring the safety of power transmission. The spacing between the five conductor cores 301 is equal. This uniform distribution helps to reduce electromagnetic interference between the cores and improve the transmission efficiency and stability of the cable. The filling layer is set between the core layer 3 and the protective layer 2, which can ensure the protective performance of the internal cores.

[0029] The working principle of this utility model is as follows: The cavity between the protective sleeve 401 and the inner lining layer 402 in the insect-proof component 4 is filled with insect-repellent agent, which can continuously release insect-repellent ingredients and effectively repel insects approaching the cable. At the same time, the serrated strips 404 on the surface of the protective sleeve 401 change the physical structure of the cable surface, making it difficult for insects to climb and attach. The polyethylene agent layer 202 in the protective layer 2 contains insect-repellent ingredients and can provide insect-proof protection from the inner layer. The diatomaceous earth adsorption layer 203 can adsorb the agent volatilized from the polyethylene agent layer 202, prolonging the agent's action time. The sealing strip 5 on the inner wall of the sealing sleeve 405 is in close contact with the outer sheath 1, which not only enhances the sealing between the insect-proof component 4 and the outer sheath 1, preventing external moisture, dust, etc. from entering and protecting the internal structure from corrosion, but also helps to prevent the leakage of insect-repellent agent and ensure the stability of the insect-proof effect.
