Abstract
The utility model relates to a circulation connection suspension welding sacrifice anode for anticorrosion of steel pipe pile, which is characterized in that the circulation connection suspension welding sacrifice anode for anticorrosion of steel pipe pile comprises an anode body having the arc-plate shape, a horizontal core plate extends from both sides of the anode body having arc-plate shape, and a vertical core plate extends from the top of the anode body having arc-plate shape. The welding-fixing operation of the sacrifice anode can be finished above water surface by the utility model. The circulation connection suspension welding sacrifice anode for anticorrosion of steel pipe pile has the advantages of simple construction, secure construction, convenient quality inspection, and easy repair and change.
Description
Technical field
The utility model relates to a kind of protective device of marine environment, particularly relates to the anticorrosion circulation connection suspension welding type sacrificial anode of using of a kind of steel pipe pile.
Background technology
When the steel pipe pile that is in marine environment is carried out cathodic protection, must weld under water by the structure of existing sacrificial anode.And the steel pipe pile that is in water turbidity, flow in the marine environment big, that wave is anxious is implemented to weld sacrificial anode under water, be undoubtedly dangerous and difficult work.
Summary of the invention
The purpose of this utility model provides the anticorrosion circulation connection suspension welding type sacrificial anode of using of a kind of steel pipe pile, and it can finish the solid welding operation of sacrificial anode more than the water surface, safe and reliable, can overcome the above-mentioned shortcoming of prior art.
The anticorrosion circulation connection suspension welding type sacrificial anode of using of a kind of steel pipe pile is characterized in that having an arc plate-shaped anode body, and it has a horizontal central layer to be stretched out by its both sides, has a vertical central layer to be stretched out by its top.
The utility model can be finished the solid welding operation of sacrificial anode more than the water surface, have construction simple, safe and reliable, be convenient to quality inspection, easy advantages such as replacement.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
The utility model has an arc plate-shaped anode body 1, and it has a horizontal central layer 2 to be stretched out by both sides, and there is a vertical central layer 3 top.Horizontal central layer 2 is used for Combination Welding between each arc plate-shaped anode body 1, and vertically central layer 3 is used for the welding between this sacrificial anode top and the steel pipe pile.The nearly time of low water, at first on the water surface, a plurality of sacrificial anodes row around steel pipe pile is established by its horizontal central layer 2 usefulness bolts series connection, fastening, welding, form ring body, then this ring body is transferred in the water, vertical central layer 3 tops on will surfacing behind the location are welded on the steel pipe pile lining.Serve as a contrast rubber pad in advance and be coated with machine oil at arc plate-shaped anode body 1 inner surface, in order to avoid ring body is transferred and is obstructed in the process and weares and teares steel pipe pile outer wall coating.The steel pipe pile lining coating of damaging during welding should in time be repaired application.According to the size difference of steel pipe pile diameter, a ring body needs 2～6 circulation connection suspension welding type sacrificial anode rows to connect formation.
To diameter in the seawater is that the steel pipe pile of 1600mm applies this anode loss protection.Steel pipe pile outer wall precoating epoxy powder, 30 years life-spans of protection.16 ℃ of seawater average temperatures, average salinity 11 ‰, Peak Flow Rate 4m/s, steel pipe pile is 12m in water, in ooze under the condition of 65m, every arc plate-shaped anode body 1 long 1200mm, wide 380mm, thick 56mm, net weight 69kg, initial stage generation electric current 0.78A.Form a ring body with 4 circulation connection suspension welding type sacrificial anodes.Whole ring body net weight 276kg, electric current 3.12A takes place in the initial stage.
