Abstract
The utility model relates to improved antiseptic cathodic protection equipment for steel buildings of submerged platforms, docks, port facilities, etc. The utility model adopts an active center suspended type auxiliary anode and a reference electrode capable of moving upwards and downwards, and has the advantages of strong versatility, and good maintenability. The utility model not only can be used for corrosion protection of fixed type ocean platforms, and steel docks and port facilities in water areas of small drop change, but also is suitable for trailing flat type or stepwise type platforms and corrosion protection of steel docks and port facilities in water areas with bigger tidal range change. The active center suspended type auxiliary anode not only can reduce the number of anodes to save energy, but also can protect potential distribution to be uniform, and protecting uniformity and effect are good under a same discharge capacity.
Description
Utility model relates to a kind of anti-corrosion cathode protection device, especially steel building anti-corrosion cathode protection device in the water body.
Very easily corrosion corrosion of steel building in the water body, especially workplatform Duan Zhong goes into steel harbour, port facilities in the seawater in the seawater, is subjected to marine denudation easily especially and corrodes.A kind of method of steel building in the water body of protecting is the employing impressed current cathodic protection, and steel building impressed current cathodic protection in the existing water, supplementary anode and reference electrode all adopt the formula that one-time fixes to install and method for arranging.Yet this formula that one-time fixes is by dress and layout; then can not be suitable for for some special occasions; waters as coastal, riverine seasonal tidal range big (tidal range reaches several meters even tens meters); meeting dry season or ebb; supplementary anode in the galvanic protection will surface and can't work; when secondly drawing type ocean platform or stepped start-stop system ocean platform were shifted, the cable of cathodic protector and lateral wall type, heavy river formula anode all can be damaged.Fixation side wall type anode is not only installed comparatively complexity, and being provided with needs underwater operation, and the anode consumption is big, and every piling bar need dispose an anode, and the Potential distribution homogeneity is also poor simultaneously.Heavy river formula anode is subject to water currents because of need are positioned riverbed or sea bed, and the fragile often cable that is shifted causes galvanic protection to lose efficacy.So fixed by dress with arrange the cathodic protection structure maintenance difficult, and because of can not demolition, disposable condemnation factor be higher.
The purpose of utility model is to overcome the deficiency of above-mentioned prior art, provides a kind of steel harbour, port facilities that are particularly useful for the big waters of mobile ocean platform and tidal range anticorrosion, and easy to maintenance by adorning, economic, cathodic protector reliably.
The utility model purpose realizes that main the improvement is with fixing supplementary anode and reference electrode by dress, changes movable the suspension by dress into.Specifically, steel body cathodic protector comprises direct supply in the utility model water, supplementary anode, and tie cable, reference electrode is characterized in that said supplementary anode is suspended on many piling bars center of support steel body, said reference electrode activity is installed on the piling bar.The utility model direct supply preferably adopts portable wall-hanging controllable direct current power supply.For adapting to different water level requirements, some hooks that are used to hang supplementary anode can be set at the different heights of piling bar.The described supplementary anode of utility model preferably places in the Pig of hollow out, Pig especially with the nylon net bag of corrosion resistant for well.Can be provided with the location under the Pig and heavily cut or polish jade with an emery wheel, influence the anode skew to prevent water stream.The said reference electrode of utility model, a kind of being preferably adopted movable flexible reference electrode, and reference electrode is movable because of fixing on the piling bar by anchor ear, makes electrode probe telescopic moving up and down.
Below, further specify utility model by the description of an indefiniteness embodiment.
Accompanying drawing is a utility model example structure synoptic diagram.
Embodiment: referring to accompanying drawing, cathodic protector is by wall-hanging controllable direct current power supply 1, supplementary anode 7, and tie cable 5, reference electrode 4 is formed.The negative pole of power supply is electrically connected with steel body 2, and the control utmost point 3 is electrically connected with reference electrode 4 with detection, and positive pole is electrically connected with supplementary anode 7, and tie cable is fixed on the piling bar 11 by movable cable fixing clamp/clip 6.Supplementary anode places netted nylon Pig 8, Pig is articulated on the piling bar suspension ring 10 by nylon lifting rope 9, and make supplementary anode remain on the many piling bar geometric centres of steel body position, and the suspension ring 10.1 and 10.2 of different heights are arranged on the piling bar, hang to adapt to different water level requirements.For preventing that ocean current from influencing the anode off normal, be hung with the location under the Pig and heavily cut or polish jade with an emery wheel 12.Detect with scalable reference electrode 4 and pass through anchor ear 13 activity orientation on piling bar, electrode probe 4.1 can be moved up and down be positioned to necessarily dark forever.When protected steel body moves, separately deposit after each parts can being unloaded, after the berth is determined, more again by dress; Or after seasonal tidal range determines, the supplementary anode lifting rope is articulated in new position, can recover to use after the energising debugging.
Steel building cathodic protector in the utility model water, owing to adopt activity centre suspension type supplementary anode and scalable mobile reference electrode, the fixing dress formula cathodic protector of pressing, improve the versatility of cathodic protector greatly, made it not only can be used for fixing steel harbour, the port facilities corrosionproof protection that formula ocean platform and drop change little waters; And suitable drawing type or stepped start-stop system ocean platform, and tidal range changes steel harbour, the port facilities corrosionproof protection in waters greatly.Supplementary anode is suspended on the geometric centre of the many piling bars of protected steel body; not only can reduce anode consumption saves energy; reduce the construction working amount; and can make supplementary anode be in the most rational Potential distribution central position; protection potential is evenly distributed; can make under same discharge capacity, it is best that the uniformity coefficient of protection and effect reach.Move or work condition environment when changing at protected steel building, for convenience detach and again by dress, can use after the energising debugging; assemble simple and direct, convenient disassembly, maintainable good, when a certain parts damages; or the supplementary anode surface is consumed the replacing convenience because of electrolytic action.
For convenience of description, said steel body of utility model and steel building are synonym.
