AUTOMATIC DEVICE FOR SELECTIVE SURFACE WASHING Russian patent published in 2023 - IPC A47L11/00 

FIELD: agricultural; municipal engineering.

SUBSTANCE: devices for autonomous wet cleaning of floors and other surfaces of agro-industrial, public and industrial premises. This is achieved by the fact that the automatic device for selective washing of surfaces contains a base frame 1 with fixed support wheels 2 to ensure stability, batteries 4, a tank 5 with washing liquid, a device 6 for regulating the supply of washing liquid. In the proposed solution, a vertical fixed rack 7 is fixed on the base frame 1, to which a horizontal rotary rod 8 with nozzles 9 and 10 is attached with the possibility of rotation around its axis and a jet positioning system is installed, including a stereo video camera 18, an on-board computer 14, servos 12, 13 with a block of servo amplifiers 15, as well as two controlled nozzles 9, 10 with the possibility of rotation through the angle of rotation q₁ around the axis of the horizontal rotary rod 8 and the angle of rotation q₂ around an axis perpendicular to the axis of rotation of the horizontal rotary rod 8, while the angles q₁ and q₂ depend on the values of the coordinates recorded by the stereo video camera 18.

EFFECT: creation of an automatic device with extended functionality for selective washing of surfaces.
