Technical Field

[0001] The utility model relates to the technical field of air cooling island cleaning, in particular to a track-walking automatic cleaning system for an air cooling island of a power plant. Background Art

[0002] At present, the air-cooling island of a power plant is affected by environmental factors, resulting in dirt and scaling on the surface of the heat sink of the air-cooling island, which greatly affects the cooling effect of the air-cooling island and the economic operation benefits of the generator set. Especially in the hot summer environment, due to the reduced heat transfer effect of the air-cooling island, the vacuum of the unit is greatly reduced and the back pressure is increased, which seriously restricts the load capacity of the unit and greatly increases energy consumption, causing great waste to the enterprise.

[0003] Therefore, in order to ensure the heat exchange efficiency of the air-cooling island heat sink, the air-cooling island heat exchange tube bundle needs to be flushed regularly, which requires a cleaning system. The existing air-cooling island is equipped with tracks to drive the cleaning equipment for horizontal cleaning. The cleaning nozzles installed on the cleaning equipment are usually unable to move, and there are blind spots for cleaning, so comprehensive flushing in the up and down directions cannot be performed. Utility Model Content

[0004] In order to make up for the above shortcomings, the utility model provides a track-walking automatic cleaning system for the air-cooling island of a power plant, aiming to improve the problem that the nozzle is usually unable to move, the cleaning range is limited and there are cleaning blind spots.

[0009] In a preferred technical solution of the utility model, the support rod slides through the slider, a circular hole matching the support rod is provided on the slider, and a gap is provided between the inner wall of the circular hole and the support rod.

[0010] In the preferred technical solution of the utility model, the transmission component includes a first sprocket, a second sprocket and a chain. The first sprocket is fixedly installed on the water outlet pipe, and the second sprocket is symmetrically fixedly installed on the support rod. The outer sides of the first sprocket and the second sprocket on each side are connected through the chain transmission.

[0011] In the preferred technical solution of the present utility model, the spray rod is symmetrically arranged on both sides of the air cooler body, and a plurality of the spray heads are equidistantly installed on the spray rod.

[0012] The beneficial effect of the utility model is that the utility model obtains a track-walking automatic cleaning system for an air-cooled island in a power plant through the above design. When in use, one end of the water source pipe is connected to one end of the second water inlet pipe, and the water source enters the first water inlet pipe from the second water inlet pipe. The water in the first water inlet pipe enters the spray rod through the guide box and the water outlet pipe, and finally is sprayed with water by the nozzle on the spray rod for cleaning. The starting motor drives the threaded rod to rotate, and the rotation of the threaded rod drives the support plate to move. The movement of the support plate drives the guide boxes on both sides to move, thereby driving the spray rod to move and flush the outside of the air-cooled machine body. At the same time, the movement of the guide box drives the support rod to move, and the movement of the support rod drives the support rod to rotate through the gear and the rack. The rotation of the support rod drives the outlet pipe to rotate synchronously through the second sprocket, the first sprocket and the chain.
