Abstract
The utility model relates to an anti-soil copper alloy drain grating water-drawing head, which is composed of a base of a water-drawing head, a drain grating of the water-drawing head, a top cover of the water-drawing head and a water channel opening, wherein the drain grating is made of anti-soil copper alloy, which effectively prevent the marine fouling growth, and the drain grating has the anti-soil ability for long especially used in the a plurality of ten years, however, other anti-soil measures need not to be adopted. Other anti-soil methods are unexampled with the anti-soil method of the drain grating. The anti-soil copper alloy has favorable resistance to sea water corrosion, therefore the corrosion rate is less than 0.1 millimeter per year. As long as the structural design is reserved with the proper allowance for corrosion, the design operation requirement for 50 years can be completely reached, that is, the utility model can be used for a long time only by one-time installation. The utility model is an excellent seawater suction device in a power plant at the seashore.
Description
Technical field
The utility model relates to power plant, a kind of strand and cools off with the dirty water intake facilities of blocking of seawater from the extraction at a distance of distance seashore.
Background technology
Utilize the strand power plant of seawater, because of the different water-supply methods of residing environment also have nothing in common with each other as cooling water.The employing basin water intaking that has, the employing water channel that has water intaking.The water channel water intaking generally has the water intaking road of hundreds of rice even last km to put in the sea, and the water channel head has a water intake, enters pipeline in order to prevent external foreign material, and water intake need be installed trashrack.To trashrack require one to be seawater corrosion resistance, the 2nd, prevent from that marine organisms from adhering to trashrack is blocked.Water intake the seabed that the position is positioned at water intaking road head is set, because of water intake is installed in the seabed, maintain and replace is difficulty very, so require the application life in 50 years.
In prior art, the water intake that adopts all steel tendon concrete structure is arranged, although reinforced concrete structure is than seawater corrosion resistance, but the appearance and size of trashrack is little, crackle is arranged unavoidably, and reinforced concrete structure will be destroyed behind the inner reinforcing bar of seawater corrosion, does not reach application life 50 years.The more important thing is that reinforced concrete structure is easy to adhere to marine organisms, marine organisms can block trashrack.
The reinforced concrete structure water intake that has adopts carbon steel or sea water corrosion resistant alloy cast iron making preferably trashrack, the metal surface adds and is coated with the nonpolluting coating that anti-marine organisms adhere to, but present nonpolluting coating can only be kept 3-5, does not reach the design instructions for use.
Summary of the invention
For solving the defective on the water intake prior art, the utility model uses the antifouling copper alloy of a kind of new material to make the water intake trashrack, electrochemical corrosion takes place in antifouling copper alloy in seawater, in this process, discharge cuprous ion, cuprous ion can destroy the marine organisms cell, plays and kills halobiontic effect, prevents component surface marine organisms apposition growth.
The minimum amount of separating out of cuprous ion takes place in the electrochemical corrosion course and will reach and prevent that marine organisms from adhering to requirement in antifouling copper alloy in seawater, generally be no less than 10 micrograms/centimetre
2My god, this is equivalent to rate of corrosion is 0.05 millimeter/year.And the rate of corrosion of antifouling copper alloy in seawater that we select for use leaves suitable corrosion allowance and just can satisfy above-mentioned service condition fully for being not more than 0.1 millimeter/year on the structure design.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of antifouling copper alloy trashrack water intake is to be made of water intake base, water intake trashrack, water intake top cover, water intake watercourse port, it is characterized in that: the water intake base is a cup-shaped structure, in the bottom or the bottom water intake watercourse port is arranged; The water intake trashrack is to be made by antifouling Cu alloy material; The cross section of water intake base is garden shape or polygon; The water intake trashrack is positioned at the top of water intake, and its material is antifouling copper alloy, and the alloying component percetage by weight is Cu:55-68, Zn:34-45, Sn:0.5-3.0.
The beneficial effects of the utility model are: antifouling copper alloy trashrack water intake adopts the antifouling copper alloy made water intake of new material trashrack, the every design instructions for use that has reasonably solved water intake.As other functional material, antifouling copper alloy has special use value as anti-fouling material.At first, antifouling copper alloy has good resistance to corrosion seawater, and annual corrosion rate is less than 0.1 millimeter.As long as leave suitable corrosion allowance on the structure design, can reach the design instructions for use in 50 years fully.The 2nd, antifouling copper alloy has the good anti-pollution function that prevents the marine organisms apposition growth, particularly in the decades of using, has antifouling ability for a long time, does not need to take other anti-pollution measure.This point is that any other anti-fouling method is unrivaled.As long as once mounting just can be used for a long time, be that the seawater device is drawn in a kind of outstanding power plant, strand.
Description of drawings
Accompanying drawing is the schematic diagram of antifouling copper alloy trashrack water intake, among the figure: 1-water intake top cover, 2-water intake top cover column, 3-water intake trashrack, 4-water intake base, 5-water intake watercourse port.
The specific embodiment
Embodiment 1 whole antifouling copper alloy formula: water intake base (4), water intake trashrack (3), water intake top cover column (2), water intake top cover (1), water intake watercourse port (5) integral body are made with antifouling copper alloy.But according to the process conditions integral cast, but also branch makes the back assembling.Generally be used for the less water intake of appearance and size, cost is higher.
Embodiment 2 steel concrete and antifouling copper alloy combination construction formula: except that water intake trashrack (3) with the antifouling Cu alloy material, water intake base (4), water intake top cover column (2), water intake top cover (1), water intake watercourse port (5) integral body are cast with steel concrete, after completing, inlay water intake trashrack (3).Cost is lower, generally is used for the less water intake of appearance and size.
Embodiment 3 alloy cast irons and antifouling copper alloy combination construction formula: use the steel concrete of embodiment 2 instead sea water corrosion resistant alloy cast iron preferably, cost is lower than embodiment 1, is higher than embodiment 2.
Circular, square, rectangle, polygon all can be done according to process conditions, geology orographic condition in the cross section of the water intake base of embodiment 4 the foregoing descriptions 1,2,3 three kind of structure.
Claims (3)
1, a kind of antifouling copper alloy trashrack water intake is to be made of water intake base, water intake trashrack, water intake top cover, water intake watercourse port, and it is characterized in that: the water intake base is a cup-shaped structure, in the bottom or the bottom water intake watercourse port is arranged; The water intake trashrack is to be made by antifouling Cu alloy material.
2, antifouling copper alloy trashrack water intake according to claim 1 is characterized in that: the cross section of water intake base is garden shape or polygon.
