The invention relates to methods and devices which are specifically intended for cleaning using a liquid by means of a pressurized or atomized jet, and especially relates to methods for the underwater hydrodynamic cleaning of hard surfaces, said methods involving installing hydrodynamic nozzles on a rotating portion of a collector, the collector being installed on a housing with support wheels, feeding pressurized water from a water pump to the hydrodynamic nozzles by means of water pipes, cleaning a hard surface using an atomized jet from the hydrodynamic nozzles, and using a propulsor for moving the device along the hard surface to be cleaned, and also relates to devices for implementing same and can be used for cleaning the underwater surfaces of vessels and for other underwater cleaning tasks. According to the invention, the propulsor is in the form of a hydraulic oil motor, the hydraulic motor is connected to oil pipes of an oil circulation system, the rate of displacement of the device is controlled using an oil-feed adjustment means, a stationary portion of the collector is connected to a convex casing which is affixed on the housing, and the degree to which the surface to be cleaned is affected is adjusted via a means for adjusting the gap between the device housing and the surface to be cleaned. The achieved technical result consists in a device which is easier to use, and in a safer method for using same. |
