Description
Technical field
The utility model relates to a kind of fin automatic washing device that is used for condenser of power station air cooling machine group; Particularly a kind of A type air cooling tubes condenser (being called for short A type island) that is mainly used in the power station direct air-cooling unit when fin cleans, can be realized used sebific duct and the cable power station direct air-cooling condenser full-automatic high-pressure water washing device of folding and unfolding voluntarily.
Background technology
At present, the A type island fin cleaning to the power station direct air-cooling unit generally is equipped with matrix-scanning-type high pressure washer structure.According to some patent documentation reports; The cleaning device that is used to clean the A type island fin of Direct Air-cooled Unit mainly contains: be CN200520068237.X " cleaning device of Air-cooled Unit " like notification number; Publication number be CN200710158436.3's " high pressure bundle array automatic cleaning device "; Publication number be CN200910066000.0's " air cooling condenser high-pressure gate-type or cantilevered track automatic cleaning device ", application publication number is " air cooled condenser cleaning system and the high-pressure hose driving device thereof " of CN201010135353.4 etc.The applicant once all was arranged on the guide rail of bracing frame or movable stand separately to the rack for cleaning that above-mentioned cleaning device exists; And vertically the driving mechanism of being made up of cog belt transmission or gear pair transmission is adopted in walking; Its structure is complicated; Take up room the lower defective of not only manufacturing cost height, and service life more; Designing a kind of patent No. is CN200920010902.8 " the vertical walking mechanism of air cooling purging system "; Disclose a kind of cleaning device that is used to clean the A type island fin of condenser direct air cooling system, overcome defectives such as parts discontinuity, wearing and tearing that the vertical walking mechanism of existing rack for cleaning exists are quite serious preferably, prolonged the service life of corresponding component to a certain extent.But in practical application, find, because its executing agency still adopts the cog belt drive mechanism, thus also exist cog belt low service life at outdoor environment, easy fracture problem such as have an accident.Design a kind of application number again is CN201010591964.X " water under high pressure purging system rack for cleaning moves executing agency " for this reason.This rack for cleaning moves the technical scheme that executing agency adopts: with the end face of the bottom surface of the cat ladder girder that moves the cat ladder frame and handrail beam respectively as the guide rail of the road wheel of rack for cleaning; The symmetry that driving mechanism adopts motor reducer to drive is assembled in the left and right reel on the same power transmission shaft; The synchronous folding and unfolding of the hauling rope of drawing through the rope guide on the left and right reel drives rack for cleaning and rises or descend along the guide rail direction that moves the cat ladder frame, so the stressed distribution of rack for cleaning is reasonable; Stable; Safe and reliable, significantly improve the service life that rack for cleaning moves executing agency, the rack for cleaning on-the-spot for washing and cleaning operation provides desirable mobile executing agency.
Take a broad view of the design feature of above-mentioned cleaning device; No matter how its horizontal mobile device designs; All there is a difficult point to overcome; That is exactly the joint of water under high pressure detergent line and the cable between the high-pressure rubber pipe between the rack for cleaning and terminal box and the control suitcase, all can not automatic deploying and retracting needs the high-pressure rubber pipe and the special cable of length along with the horizontal displacement that moves the cat ladder frame.In the use, its sebific duct and cable all are on the unordered about one meter wide grid passageway that is deposited between two A type islands to above-mentioned cleaning device at the scene.When tens meters sebific ducts with cable is unordered when mixing; Be difficult to avoid the winding of sebific duct self or cable self; And the mutual winding between sebific duct and the cable; The washing and cleaning operation of existing automatic flushing device all can not be realized the automatic deploying and retracting management of sebific duct and cable, all needs people's manual arrangement in the horizontal moving process that moves the cat ladder frame at the scene and pulls cable and sebific duct.Especially in summer during washing and cleaning operation; General minimum five, 60 degree that all reach of temperature on the grid, it is consuming time long again to add washing and cleaning operation, condenser heat radiation agreement that contracts a film or TV play to an actor or actress tens days the time of needs of cleaning power plant's 300,000 generating sets with the cleaning way of matrix-scanning; If long-term operation is in the environment of such high temperature mal-condition; Utilize manual work to pull cable and sebific duct, not only labour intensity is big, and can be to the human injury.If but untimely arrangement pulls, in case tens meters sebific duct is intertwined or sebific duct and cable between when twining each other, will cause the security incident of washing and cleaning operation.Therefore, washing and cleaning operation is realized complete automatic deploying and retracting management having become a great problem that needs to be resolved hurrily of sebific duct and cable.
