Description
Technical Field
The utility model relates to an insulating anticorrosive technique of boats and ships, in particular to anticorrosive insulating ground connection crossing cabin spare of boats and ships.
Background
The generator, the main engine, the steering engine, the hardware and the electrical equipment shell on a common aluminum ship can form a primary battery with a ship aluminum plate to generate a certain current, and the metal activity of aluminum is more active, so that the aluminum plate can be corroded. The metal activity of the zinc block is larger than that of aluminum, so that the zinc block has a certain protection effect on the aluminum plate. At present, the problem of corrosion resistance is generally solved by mounting a non-insulating zinc block on the surface of an aluminum ship, but the aluminum ship does not have a special Impressed Current Cathodic Protection (ICCP) system for protecting the discharge of electrical equipment, so that the aluminum ship can generate an electrochemical corrosion phenomenon, and the service life of the ship is reduced.
SUMMERY OF THE UTILITY MODEL
For solving the anticorrosive problem of aluminium ship, the utility model provides a cabin spare is worn to anticorrosive insulating ground connection of boats and ships to extension boats and ships life-span is through carrying out ground connection to whole aluminium ship on-board large-scale electrical equipment, utilizes in each region to carry out centralized the zinc piece that converges to boats and ships afterbody and hull insulation with the insulating ground connection row of hull to reach release current and guarantees that aluminium ship is not by the mesh of electrochemical corrosion.
The utility model discloses a realize like this. A ship anti-corrosion insulation grounding cabin penetrating piece comprises a zinc block, a screw rod and a Teflon sleeve, wherein threads are arranged at two ends of the screw rod, the zinc block is fixedly arranged at one end of the screw rod through a fixing nut, the screw rod is sleeved with the step-shaped Teflon sleeve, threads are arranged on the periphery of a step column of the Teflon sleeve and penetrate through a through hole of a ship aluminum plate, sealant is injected between the screw rod and the inner hole of the Teflon sleeve, the sealant is injected at the joint of the periphery of the Teflon sleeve and the ship aluminum plate, the step column of the Teflon sleeve is in threaded connection with a self-locking nut, a gasket is arranged on the inner side of the self-locking nut, and the sealant is injected between the gasket and the ship aluminum plate; the other end of the screw rod is connected with a grounding wire and a fixing nut.
The utility model provides a zinc plate and aluminium ship inside electrical equipment's ground connection installation, avoided the contact of zinc plate and hull again simultaneously, reached the electrochemical corrosion who places large-scale electrical equipment, extension boats and ships life-span.
Drawings
Fig. 1 is a schematic structural view of the cabin penetrating member of the present invention.
In the figure: 1. the aluminum hull aluminum plate comprises a zinc block, 2 parts of a gasket, 3 parts of a Teflon cushion, 4 parts of a grounding wire, 5 parts of a screw rod, 6 parts of a fixing nut, 7 parts of a Teflon sleeve, 8 parts of a self-locking nut, 9 parts of sealant and 10 parts of a hull aluminum plate.
Detailed Description
The present invention will be further explained with reference to the drawings and examples. Referring to fig. 1, anticorrosive insulating ground connection cabin spare of crossing of boats and ships includes a zinc block 1, a screw rod 5 and teflon sleeve 7, is provided with the screw thread at the both ends of screw rod 5, and the one end of screw rod 5 is equipped with a zinc block 1 through 6 fixation clamps of two fixation nut, and the cover is equipped with step-like teflon sleeve 7 on the screw rod 5, and the step post periphery of teflon sleeve 7 also is provided with the screw thread and passes the through-hole that is equipped with on the hull aluminum plate 10 and pass through self-locking nut 8 installation fixed. Sealant 9 is injected between the screw 5 and an inner hole of the Teflon sleeve 7, and the sealant 9 is also injected at the joint of the periphery of the Teflon sleeve 7 and the hull aluminum plate 10. The step column of the Teflon sleeve 7 is in threaded connection with a self-locking nut 8, a gasket 2 is clamped in the middle of the step column, and sealant 9 is injected between the gasket 2 and a hull aluminum plate 10; the other end of the screw 5 is connected with a grounding wire 4 and fixed by a fixing nut 6.
The utility model discloses an installation as follows:
the first step is as follows: a through hole is formed in the hull aluminum plate 10, and the aperture size of the through hole is slightly larger than 1mm of the outer diameter of the Teflon sleeve 7;
the second step is that: coating a sealant 9 on the periphery of the through hole of the aluminum plate 10 of the ship body, wherein the sealant 9 adopts the Xika 5200 and is slow-drying;
the third step: a Teflon sleeve 7 is arranged in a through hole of the hull aluminum plate 10, and the Teflon sleeve 7 adopts a polytetrafluoroethylene rod as a lathe machined part;
the fourth step: a Teflon sleeve 7 penetrates through a through hole of a hull aluminum plate 10, a gasket 2 is clamped between the inner wall of the hull aluminum plate 10 at the thread position of the Teflon sleeve 7 and a self-locking nut 8, and a sealant 9 is arranged between the gasket 2 and the inner wall of the hull aluminum plate 10;
the fifth step: coating a sealant 9 on the screw rod 5, penetrating the screw rod 5 through an inner hole of a Teflon sleeve 7, installing a Teflon cushion 3 (made of polytetrafluoroethylene) and two fixing nuts 6 at the end of the screw rod 5, and clamping a grounding wire 4 between the two fixing nuts 6;
and a sixth step: after waiting for 12 hours, carrying out an experiment by using vacuumizing equipment, checking the air tightness, and after confirming that the requirement is met, fixedly mounting the zinc block 1 on an outer screw 5 of the hull aluminum plate 10 through two fixing nuts 6, wherein the mounting position of the zinc block 1 is below the waterline of the ship.
