This disclosure relates to system and method for cleaning surfaces using drones. The method includes identifying, by a first drone, a cleaning strip in contact with a surface. The cleaning strip connects a second drone and a third drone. The second drone is communicatively coupled with the third drone. The first drone is communicatively coupled with each of the second drone and the third drone. The method further includes releasing a cleaning agent at a preconfigured pressure upon a current target region of the surface near the cleaning strip. The method further includes relocating the cleaning strip upon the current target region. The method further includes performing a set of oscillations through the cleaning strip across the current target region. Each of the set of oscillations includes coordinating a displacement of the cleaning strip by a predefined distance, alternating towards each of ends of the cleaning strip.

An underwater vehicle is provided for cleaning, inspection and/or monitoring of underwater structures A. The vehicle includes at least one working equipment for cleaning, inspection and/or monitoring of underwater structures A. Several interconnected modules are also provided which can be oriented relative to each other. The modules are arranged one behind the other, and the underwater vehicle can be transitioned from an elongated movement configuration into a U-shaped, C-shaped, spiral and/or an annular working configuration and back.

The present invention relates to self powered and timer based solar panel cleaning system that is operated by self generating electrical power from solar energy and reduces wear and tear problem of moving parts. In this system, the microcontroller (54) is interfaced with motor driver (51) and brush driver (52). Said motor driver (51) and brush driver (52) control the speed of wheel motor (32) and brush driver (33). When ultrasonic sensor (5) sends signal to microcontroller (54), said microcontroller (54) generates and transmits signal to wheel motor driver (51) and brush driver (52). Thus, when structure reaches nearby the end edge of the solar panel array, said drivers gradually reduce r.p.m. of wheel motor (32) and brush motor (33) and then motors stop when machine reaches to opposite platform. Thus, during alteration of mode, r.p.m. of motors will be at substantially low that prevents the moving parts from damage.

A window washing assembly includes a first roller bar and a second roller bar affixed within a window frame. The assembly includes a first pulley coupled to the first roller bar and the second roller bar. The assembly includes a second pulley parallel to the first pulley and coupled to the first roller bar and the second roller bar. The assembly includes a wiper arm coupled to the first pulley and the second pulley, wherein the wiper arm includes at least one spray nozzle, a wiper blade, and at least one magnet. The assembly includes a motor coupled to the first or second roller bar. The assembly includes a first magnetic stop and a second magnetic stop. The assembly includes a cleaning fluid reservoir fluidly coupled to the one or more spray nozzles of the wiper arm.

A seaming roller cleaner includes a base body, on which a driven roll receptacle and a non-driven roll receptacle are mounted. The roll receptacles are used to receive paper web rolls. The paper web roll includes a cleaning web, and the base body provides a support over which the cleaning web is laid to define a cleaning surface. The cleaning web is drawn by the driven roll receptacle in the direction of the driven roll receptacle. The non-driven roll receptacle is passively rotated and may be slightly braked to prevent rotating too quickly. The support includes a carrier plate and an elastomer. The seaming roller may be arranged at an oblique angle relative to the direction of the cleaning web is drawn, such that the seaming roller is wiped and slowly rotated by the cleaning web.

A pipe coating removal apparatus (1) for removing all or some of the coating on a pipe, the pipe coating removal apparatus (1) having a pipe support means (2) for supporting a length of pipe. and further having a tool carriage (3). The tool carriage (3) being capable of supporting two or more different types of pipe coating removal tools (4), (5), (6), (7), (8), (80), (81), (82) and/or (70). The pipe coating removal apparatus (1) being capable of causing relative movement between the tool carriage (3) and the pipe support means (2) to remove all or some of the coating on the pipe that is supportable by the pipe support means (2).

An aircraft windshield wiper system includes a wiper arm, a wiper blade coupled to a first end of the wiper arm, and an output shaft coupled to a second end of the wiper arm. The wiper blade includes a fluid dispensing system including nozzles, a fluid control unit, fluid lines, fluid source, and a user interface. The wiper blade with the fluid dispensing system is configured to dispense a variety of fluids directly from the wiper blade onto the windshield of an aircraft.

A method of cleaning a controlled and regulated equipment, the method comprising the steps of: (1) forming a tool handle by removably connecting a first handle portion to a second handle portion; (2) pivotably connecting a tool head frame to the second handle portion; wherein the tool head frame comprises a leading edge opposite a trailing edge and a first side edge opposite a parallel second side edge disposed between the leading and the trailing edge respectively, wherein the leading edge and the trailing edge are non-parallel to each other; (3) positioning the tool head frame in proximity to a tray having at least one compartment, a pad assembly and a cleaning solution, wherein the pad assembly and the cleaning solution are disposed in the at least one compartment; (4) configuring the pad assembly to be movable within the at least one compartment between a first position and a second position; and (5) attaching the tool head hands-free to the pad assembly in the first position or second position and detaching the tool head hands-free from the pad assembly in the second position. The method further comprises the steps of providing a precise amount of cleaning solution within the at least compartment in order to provide accurate saturation and consistent moisture level for each pad within each pad assembly.

Provided is an optical connector cleaning tool with a simple structure that can sufficiently transmit transmission force. The optical connector cleaning tool includes a supply reel on which a cleaning material is wound so that it can be fed out, a winding reel that winds the cleaning material that has passed through a cleaning head, an operating body that can be pivoted by operation by an operator, and a rotary engaging body that engages with the operating body to transmit the movement of the operating body to rotate the winding reel, in which the arc caused by the pivoting of the operating body is inscribed in the arc caused by the rotation of the rotary engaging body, and the operating body and the rotary engaging body are engaged.

In a chemical mechanical polishing system, a platen shield cleaning assembly is installed on a rotatable platen in a gap between the rotatable platen and a platen shield. The assembly includes a sponge holder attached to the platen and a sponge. The sponge is held by the sponge holder such that an outer surface of the sponge is pressed against an inner surface of the platen shield.
