Cleaning equipment on radiator tower
Technical Field
The utility model relates to a radiator cleaning equipment technical field, in particular to cleaning equipment on radiator tower for wind power generation.
Background
The wind driven generator mainly comprises a permanent magnet direct drive type fan and a double-fed type fan, wherein the two fans need to use a frequency converter, and the frequency converter is used for enabling the power generation energy of the fans to meet the requirements of a power grid. The frequency converter is accompanied with heat accumulation during operation, so a radiator is used. The inside of the radiator is often generated with water scale and is mixed with a plurality of impurities to cause line blockage, thus leading to poor heat dissipation effect. Particularly, under the condition of high-temperature wind in summer in the south, water scales and impurities are easily generated, and the fan has to be operated in a load-limiting mode, so that the power generation efficiency is influenced. In addition, the water scale and impurities inside the radiator can affect the service life of each component inside the frequency converter.
In order to improve the working efficiency of the radiator, the inside of the radiator must be cleaned frequently, but no special equipment for cleaning the fan radiator on the tower of the wind driven generator exists at present, so that the design of the cleaning equipment on the radiator tower of the wind driven generator is really necessary.
