The permanent magnet adsorbing installation is adopted for the utility model, and the built-in costal plate is cast by the steel material, and a contact electrode is arranged on the contact surface of the protected steel structure, so that the installation and exchange are convenient, and the operation is reliable, and can be extensively applied in corrosion protection of the underwater steel structures as a drilling platform, a submarine pipeline and a bridge and so on.
Description
Technical field
The utility model relates to cathode protection technology, particularly relates to a kind of magnetic adsorption type sacrificial anode.
Background technology
In the industry of ocean, often need in seawater, install steel construction, lay submerged pipeline etc., particularly in marine oil industry, pipeline under the ocean, drilling derrick etc. all need to work in seawater for a long time, in order to prolong the work-ing life of submerged pipeline, steel construction piece, must take effective anticorrosive measure to it, otherwise be easy to be fallen by sea-water corrosion.For preventing sea-water corrosion, method in common is to adopt galvanic anode protection.Sacrificial anode commonly used at present mainly contains zinc and zinc alloy, magnesium and magnesium alloy, aluminium and aluminium alloy.
Sacrificial anode is in the past mainly installed by the mode of welding, and the sacrificial anode of welded and installed all needs to carry out specialty when changing and cuts under water it is separated just installing, and then welds new sacrificial anode.Change a sacrificial anode and often will drop into more manpower and long duration of cost.In order to change sacrificial anode, also to handle protected surface and check sometimes with special mechanical means, for example utilize crawl device to carry out the surface attachments cleaning of drilling derrick underwater steel construction, and the submerged pipeline inspection etc.For this reason, the parties concerned have dropped into the improvement that many man power and materials carry out sacrificial anode device, have obtained certain progress.As patent " a kind of seawater pipeline sacrificial anode protection device " (patent No. is ZL 03253305.5).This patent disclosure a kind of sacrificial anode protection device that is mainly used in the naval vessel seawater pipeline, adopt the flange ways of connecting to be fixed on the pipeline, with conductor wire sacrificial anode is connected with seawater pipeline again.The installation method that this patent is more traditional has certain improvement, but can only be used for the protection of naval vessel seawater pipeline, and installs still relatively more difficult.
About be used for drilling unit, oil pipeline etc. under water the sacrificial anode device of large-scale steel structure corrosionproof protection be not reported.
Summary of the invention
The purpose of this utility model is that needle has problems to above-mentioned prior art, and a kind of new sacrificial anode device is provided, and this device use range is extensive, and it is convenient to install, change.
Therefore the utility model proposes a kind of magnetic adsorption type sacrificial anode.Adopt aluminum alloy materials as sacrificial anode, install by the mode of permanent magnet absorption, the permanent magnet surface adds water-proof coating and seawater is isolated, and prevents that permanent magnet self from corrosion taking place sacrificial anode is come off; In order to make sacrificial anode and underwater steel construction material realize the good electron exchange, contact surface is provided with pre-compression type contacts electrode, and the contact position of this contacts electrode and steel construction seals with rubber cup, prevents the corrosion of seawater butt contact.The sacrificial anode appearance design is an arc surface, and the profile of contact surface, radius can be determined according to the shape that is touched face.Its concrete technical scheme is as follows: it mainly is made up of sacrificial anode, built-in floor, permanent magnet module and contacts electrode.Wherein sacrificial anode adopts aluminum alloy materials to make, and built-in floor is arranged in the sacrificial anode, is formed by the steel material casting, and the permanent magnet module is placed in the bar hole that is provided with on the sacrificial anode, adds corrosion protection coating; Contacts electrode is installed on the built-in floor, and is connected with built-in floor by lead.
The utlity model has following beneficial effect:
The utility model adopts the permanent magnet suction type to install, and need not underwater operations such as welding, cutting, thereby fitting operation is simple, and dismounting and change is convenient, and is applied widely; Because permanent magnet module surface is provided with corrosion protection coating, can prevent the corrosion of seawater in addition to the permanent magnet module, thereby long service life, safe and reliable.
