Description
Technical Field
The invention belongs to the technical field of cables, and particularly relates to a cable for a shore power system.
Background
The shore power utilization technology for ships refers to that all power utilization of power generated on the ships is guaranteed by the ships during the ships approach, and has important economic, social and environmental benefits for energy conservation, emission reduction, green economy and environmental management.
The shore power system is connected between shore power box and boats and ships with the cable, often is dragged and takes place the friction with ground, cabin in the use, when connecting boats and ships and shore power, because dead weight, hull rock and blow, unsettled cable can be dragged, easy damage.
In order to stably operate the shore-approaching ship, a cable having a damage alarm function needs to be designed to meet the use requirement.
Disclosure of Invention
In order to meet the requirements, the invention provides a cable for a shore power system, which has a damage alarm function, ensures the safety of the production operation of a wharf and is suitable for the shore power system.
The technical scheme adopted by the invention for solving the technical problems is as follows: the utility model provides a shore power cable for system, includes the cable core, the cable core is formed by a plurality of wire transposition, the cable core is equipped with the polytetrafluoroethylene layer outward, the polytetrafluoroethylene layer is equipped with the yarn layer that blocks water outward, the yarn layer that blocks water is equipped with the deliquescence layer outward, the deliquescence in situ is equipped with spiral winding's hose, the hose is the water-soluble material, hose one end is equipped with pressure sensor, pressure sensor links to each other with alarm device, the deliquescence layer is equipped with thermal-insulated fiber layer outward, the thermal-insulated fiber layer is equipped with the high density polyethylene layer outward, the high density polyethylene layer is equipped with the polyurethane restrictive coating outward.
Preferably, the structure of the wire is as follows: the innermost layer is the copper core, the copper core is equipped with irradiation crosslinked polyethylene layer outward, irradiation crosslinked polyethylene layer is equipped with the nylon cloth layer outward, the nylon cloth layer is equipped with the aluminium foil layer outward.
Preferably, one end of the hose is divided into two fork heads, one fork head is provided with a pressure sensor, the pressure sensor is connected with the alarm device, and the other fork head is provided with an inflation valve.
Preferably, the hose is made of polyvinyl alcohol.
Preferably, the material of the heat insulation fiber layer is any one of glass wool fiber, phenolic fiber or ceramic fiber.
Deliquescence refers to the phenomenon in which some substance absorbs or adsorbs water from the air, causing the surface to become increasingly moist and lubricious, and eventually the substance changes from a solid to a solution of the substance.
Inject gas in toward the hose through the inflation valve, and then make pressure sensor sense pressure, appear damaging when the cable, the deliquescent object will expose, the deliquescent object is unstable, can absorb the water in the air in a large number, form the water solution and dissolve the hose of water-soluble material, pressure sensor in the hose just senses pressure drop like this, when pressure drops to a definite value, alarm device will remind maintainer, the maintainer arrives earlier past the inflation valve after the scene, observe a period of time, can the secondary alarm, get rid of because natural gas leakage arouses the warning, if there is the damage, according to discovering the gas leakage point through aerifing, confirm concrete damaged position.
The hose is helically wound within the cable to ensure that any point of failure can be detected.
The heat insulation fiber is fluffy, provides space for subsequent inflation and expansion of the hose, and can protect deliquescent substances in the hose.
Because the pressure relief alarming mode is adopted, the cable is prevented from being curled and pressed in daily use to cause false alarm, the pressure sensor is arranged at the end head, so that the pressure sensor can be placed in an electric box or other dry and stable environments, the damage is not easy, and the alarming reliability is ensured.
The invention has the beneficial effects that: the system has the function of breakage alarm, ensures the safety of wharf production operation, and is suitable for a shore power system.
