Description
Technical field
The utility model relates to a kind of anti-fouler of propeller for vessels, particularly relates to a kind of portable screw propeller anti-fouler peculiar to vessel.
Background technology
The long-term landing pier of the boats and ships that some rate of sailing is low, because its screw propeller remains static, the marine life young is very easy to be attached on blade, and these young continue attachment when flow velocity is larger, and development by metamorphosis growth.In natural marine site, the unimpeded environment of current is because being conducive to ingesting, and the growth of attaching organism can be vigorous especially.Screw propeller be subject to halobiontic stained after, resistance and the fuel oil consumption of ship's navigation can be added, reduce the speed of a ship or plane, change blade metallic surface feature simultaneously, increase blade surface roughness, accelerate the corrosion of blade, force boats and ships frequently to enter dock trimming, cause boats and ships to sail the heavy losses such as rate reduction, shortening in service life.
The mode of existing screw propeller sea marine organism pollution preventing mainly contains the technological means such as labor cleaning, metal coating method, electrolysis antifouling.Labor cleaning be utilize orderly closedown during carry out operation, carry special tool to carrying out labor cleaning under water by diver, the marine life that screw propeller adheres to removed by use instrument, its elimination efficiency is not high, and easily damage screw propeller, destroy the smooth degree on its surface, increase propeller noise; Metal coating method utilizes the cuprous ion discharged in coating to form one deck cuprous oxide film at coating surface, namely this tunic can kill the marine life being attached to screw propeller surface, new sea organism attachment can be prevented again, reach with this object preventing fouling organism from adhering to.But current nearly all propeller for vessels position is all applied with cathode protection; this technology inhibits the dissolving of metallic ion in metal nonpolluting coating; although the method extends the service life of metallic coating, its anti-fouling effect is almost nil, thus causes coating failure.Electrolyzing seawater antifouling technique has applied 30 years for many years in Coastal Power Plant, its anti-fouling effect is good, the halobiontic attachments such as germ, algae, shellfish can be prevented, this technology is mainly used in recirculating cooling water system, and mainly solves in this open system of screw propeller and how to be transported to around blade by battery acid (liquor natrii hypochloritis) and electrolysis system placement location problem.
Two patent reports are had about the technical scheme that electrolytic seawater helical oar is antifouling.One is that Chinese patent 201010243815.4 discloses a kind of propeller shore-based electrolytic seawater antifouling system, and this system is made up of Switching Power Supply and preparing chlorine by electrolysis device.Preparing chlorine by electrolysis device comprises fixed frame and assisted electrolysis electrode, and fixed frame can be moved freely by the sliding support be fixed on the bank.When after boats and ships landing pier, by sliding support on the bank, preparing chlorine by electrolysis device is placed on the bottom of screw propeller.But propeller for vessels all can oscillate in upper and lower, left and right at any time, and according to different sea conditions, rocking tendency also difference is very large, need the situation of waving according to screw propeller and the continuous mobile fixed frame of change in location, otherwise be in around open system screw propeller and be difficult to ensure enough antifouling concentration, this localization method is wasted time and energy, and is difficult to realize in real world applications.Another Chinese patent CN 201010573328.4 reports a kind of for propeller for vessels antifouling system, and this system comprises bank base and moves Electrolyzed sea water chlorination device, underwater automatic positioning device and on-line monitoring chlorine residue device.Seawater is introduced the portable Electrolyzed sea water chlorination device of bank base by this system, underwater automatic positioning device is utilized to be ejected into around propeller blade by battery acid, controlled by density of sodium chlorate around on-line monitoring chlorine residue measurement device screw propeller, feed back to preparing chlorine by electrolysis device and regulate current control liquor natrii hypochloritis concentration.This system exists screw propeller equally can depart from the situation of original position along with sea conditions, needs underwater automatic positioning system to change position at any time, to guarantee the antifouling concentration of sodium hypochlorite around screw propeller.Meanwhile, this bank base moves preparing chlorine by electrolysis device composition relative complex, and underwater automatic positioning device and online residual chlorine monitoring device both increase operation difficulty, propose harsh requirement to whole system maintainability and stability.
