Abstract
Description
Technical Field
[0001] This utility model relates to the field of ship demagnetization technology, and in particular to a demagnetization cable structure. Background Technology
[0002] Ordinary warships are built with ship steel. During use, due to the magnetic fields generated by the operation of their internal magnetic equipment and the influence of the Earth's magnetic field, magnetic fields remain on the metal hull of the warship. Warships with magnetic fields are more easily identified by magnetic weapons such as magnetic mines during navigation, increasing the risk of being attacked. They are also more easily detected by enemy magnetic detection radar, increasing the risk of being exposed. Therefore, it is usually necessary to demagnetize the ships regularly.
[0003] Currently, warship demagnetization typically employs magnetic cables. These cables are specifically designed for ship demagnetization, their primary function being to transmit demagnetizing current. By generating a magnetic field opposite to the ship's magnetic field, they neutralize the ship's magnetism. These cables are commonly used in temporary coil demagnetization systems or fixed demagnetization systems at demagnetization stations. When demagnetization is required, the cable is wrapped around the outside of the ship before energizing. However, because warships are usually at sea in complex marine environments, they are subject to constant rolling and pitching. When the demagnetizing cable is wrapped around the hull or other metal surfaces, it is prone to loosening or shifting, negatively impacting the demagnetization effect. Utility Model Content
[0004] This application provides a demagnetizing cable structure to achieve demagnetization and improve the stability of cable positioning on ships.
[0005] This application provides a demagnetizing cable, comprising:
[0006] conductor;
[0007] An insulating layer is formed by covering the outside of the conductor.
[0008] Inner sheath, covering the outside of the insulating layer;
[0009] An outer sheath covers the outside of the inner sheath;
[0010] Connectors are spaced apart on the outside of the outer sheath along the length of the outer sheath.
[0011] An adsorption element is connected to the connecting element, and the adsorption element is used to adsorb and connect with the outer wall of the ship.
[0012] The beneficial effects of the above embodiments are as follows: the conductor generates an external reverse magnetic field on the ship, which reduces or eliminates the magnetic field on the ship's metal hull. The inner and outer sheaths improve the protective performance of the demagnetizing cable, thereby improving the demagnetizing cable's resistance to the harsh marine environment. At the same time, the adsorption component can directly adsorb the demagnetizing cable onto the outer wall of the ship, improving the stability of the demagnetizing cable's positioning, thereby improving the demagnetizing effect.
[0013] Based on the above embodiments, the embodiments of this application can be further improved as follows:
[0014] In one embodiment of this application: the connector is a collar, which is fitted onto the outside of the outer sheath. The advantage of this step is that the collar structure facilitates the connection of the adsorption element to the surface of the demagnetizing cable.
[0015] In one embodiment of this application: the connector is a connecting strap, and the two ends of the connecting strap are connected by Velcro to form a loop structure. The advantages of this step are: the connector with a Velcro structure is low-cost, easy to disassemble and replace, and facilitates later maintenance.
[0016] In one embodiment of this application, the device further includes a first protrusion and a second protrusion, wherein the first protrusion is disposed on the connector, and the second protrusion is disposed on the adsorption element, and the first protrusion and the second protrusion are detachably connected. The beneficial effect of this step is that designing the connector and the adsorption element as a detachable structure facilitates the individual replacement of either the connector or the adsorption element later.
[0017] In one embodiment of this application, a groove is provided on the outer periphery of the first protrusion. The advantage of this step is that it facilitates the operator's grip on the first protrusion.
[0018] In one embodiment of this application: the first protrusion and the second protrusion are threadedly connected. The advantage of this step is that the threaded connection structure is easy to implement.
[0019] The second aspect of this application provides that the adsorption member has a rotating hole along the axis of the second protrusion for inserting a hexagonal wrench. The beneficial effect of this step is that by inserting the hexagonal wrench into the rotating hole to drive the adsorption member to rotate, the adsorption member can be stably connected to the connector.

[0025] Example 1
[0026] like Figure 1 As shown, a demagnetizing cable includes: a conductor 1, an insulation layer 2, an inner sheath 3, an outer sheath 4, a connector 5, and an adsorption member 6. The insulation layer 2 covers the outside of the conductor 1, the inner sheath 3 covers the outside of the insulation layer 2, and the outer sheath 4 covers the outside of the inner sheath 3. The connector 5 is spaced along the length of the outer sheath 4 on the outside of the outer sheath 4. The adsorption member 6 is connected to the connector 5 and is used to adsorb and connect with the outer wall of the ship.
[0027] Specifically, conductor 1 is made of tin-plated copper. Tin-plated copper conductor 1 is relatively soft and has good conductivity. Compared with bare copper wire, it has stronger corrosion resistance and oxidation resistance, which can greatly extend the service life of the cable.
[0028] Specifically, insulation layer 2 is made of ethylene propylene rubber. This material has excellent electrical insulation properties, which can effectively isolate current and prevent short circuits or leakage in cable conductor 1. Ethylene propylene rubber also has strong heat and cold resistance, making it suitable for use in variable environments.
[0029] Specifically, the inner sheath 3 is made of chlorosulfonated polyethylene rubber sheath. Chlorosulfonated polyethylene material has strong corrosion resistance, UV resistance and aging resistance, and can resist the corrosion of environmental factors such as seawater and salt spray, protect the internal structure of the cable from external damage, and enhance the mechanical compressive strength of the cable.
[0030] Specifically, the outer sheath 4 uses a polyether polyurethane protective layer. The polyether polyurethane material provides additional protection and has strong oil resistance, tensile strength and weather resistance. It can not only effectively prevent mechanical wear, but also maintain the cable in good condition when exposed to harsh environments for a long time.
[0031] Specifically, connector 5 is a collar, which is fitted onto the outside of outer sheath 4. Through the collar structure, it is easy to connect adsorption component 6 to the surface of demagnetizing cable. The collar can be made of rubber or plastic. Alternatively, connector 5 can also be made of connecting strap, with the two ends of the connecting strap connected by Velcro to form a collar structure. This structure has the characteristics of low cost, easy disassembly and replacement, and facilitates later maintenance.
[0032] Specifically, the adsorption component 6 uses suction cups, which are installed on the surface of the demagnetizing cable every five meters via the connector 5.
[0033] Specifically, such as Figure 1 As shown, the magnetic cable also includes: a first protrusion 7 and a second protrusion 8. The first protrusion 7 is disposed on the connector 5, and the second protrusion 8 is disposed on the adsorption component 6. The first protrusion 7 and the second protrusion 8 are detachably connected. The first protrusion 7 and the connector 5 can be integrally formed, or the first protrusion 7 can be glued to the connector 5. The second protrusion 8 can be integrally formed with the adsorption component 6, or the second protrusion 8 can be glued to the back of the adsorption component 6. By designing the connector 5 and the adsorption component 6 as a separable structure, it is convenient to replace the connector 5 or the adsorption component 6 separately in the future.
[0034] Specifically, such as Figure 1 As shown, the first protrusion 7 has a groove 701 on its outer periphery, which makes it easier for the operator to hold the first protrusion 7.
[0035] Specifically, the first protrusion 7 has a threaded hole 702 along the axis, and the second protrusion 8 has an external thread on its outer periphery. The first protrusion 7 and the second protrusion 8 are threadedly connected, and the threaded connection structure is easy to implement.
[0036] Specifically, the adsorption component 6 has a rotating hole 801 along the axis of the second protrusion 8 for inserting a hexagonal wrench. By inserting the external hexagonal wrench into the rotating hole 801 to drive the adsorption component 6 to rotate, the adsorption component 6 can be stably connected to the connector 5.
[0037] When in use, this type of demagnetizing cable is wrapped around the outer circumference of the ship and connected to the outer wall of the ship by adsorption component 6, so as to stably position the demagnetizing cable on the surface of the ship, thereby ensuring the stability of the reverse magnetic field. When conductor 1 is energized, a reverse magnetic field for demagnetization is generated, which reduces or eliminates the magnetic field on the metal hull of the ship, thereby realizing the demagnetization operation of the ship.
[0038] Example 2
[0039] Based on Example 1, the demagnetizing cable also includes: a temperature-sensing optical fiber, which is twisted together with conductor 1 and connected to the electrical signal of the control system. The heat of conductor 1 during the demagnetizing process is measured through the temperature-sensing optical fiber.
[0040] When the cable temperature exceeds the preset safety threshold, the temperature sensing fiber transmits the temperature data to the control system. The control system reduces the heat dissipation of the cable by reducing the current load, thereby preventing performance degradation or damage caused by overheating.
[0041] The above are merely embodiments of this utility model. Commonly known structures and characteristics are not described in detail here. Those skilled in the art are aware of all common technical knowledge in the field prior to the application date or priority date, are aware of all existing technologies in that field, and have the ability to apply conventional experimental methods prior to that date. Those skilled in the art can, based on the guidance provided in this application, improve and implement this solution in combination with their own capabilities. Some typical known structures or methods should not be obstacles for those skilled in the art to implement this application. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model. These should also be considered within the scope of protection of this utility model, and will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
