Hariharan2 1Assistant Professor, 2UG Scholar, 1,2Department of Mechanical Engineering, Sri Shakthi Institute of Engineering and Technology, Coimbatore, Tamil Nadu, India ABSTRACT Window panel cleaning makes the building’s architectural glass free from dust and dirt. The traditional way of cleaning office windows cannot be applied to high-rise windows with huge sections of glass. Cleaning the windows from outside requires special tools in going up and it’s unsafe. The Window cleaner proposed is a device that would be controlled by using a microcontroller. This device would be safer compared to traditional methods of window cleaning in case of high glass structures that increase the risk of loss of human life. The structure of the proposed device consists of a triangular frame and uses a suction cup-based adhesion technique to adhere to the glass surface. The movement of the frame over the glass is done by using special rigging. The frame consists of an automated cleaner which is run by motors and pre- programmed microcontrollers. The automated cleaner moves in the vertical direction within the frame. KEYWORDS: Motor, glass, window, frame, brush How to cite this paper: A. Arun Negemiya | P. Aswathraj | S. Balaji | M.

These systems are mainly adopted in places where direct access by a human operator is very expensive, because of the need for scaffolding, or very dangerous, due to the presence of a hostile environment. As the results of surveying the requirements for the wall-climbing machine, the following points are necessary for providing the machine for practical use: It should be small in size and lightweight for portability. Automatic operation during moving. A wall-climbing machine should be light and allow a large payload, reducing excessive adhesion forces and carrying instrumentations during navigation. Up to now, considerable research was devoted to these machines and various types of experimental models were proposed. The two major issues in the design of wall-climbing machines are their locomotion and the adhesion methods. Concerning the locomotion type, three types are often considered: the crawler, the wheeled, and the legged types. According to the adhesion method, these machines are generally classified into three groups: vacuum or suction cups, magnetic, and gripping to the surface. Recently, new methods for assuring the adhesion, based on biological findings, have also been proposed. This procedure may be repeated until the entire building has been washed. Cleaning windows using scaffolding is extremely time-consuming. To reduce time and cost, therefore being more competitive in the industry, Window washers tie a climbing rope to the roof anchors provided for the scaffolding and throw the rope over the side of the building. Then they attach a boson's chair to the rope and a climber’s harness to themselves with repelling hardware. The mangoes over the side of the building with his tools and Water/soap bucket and cleans 6-8 horizontal glass Width per story. Then repels down to the next level and repeats until that drop is complete. Manual Washing of buildings has proven to be quite dangerous, especially concerning tall skyscrapers. Typical Wind and air drafts surrounding. Arun Kumar et al., (2017) described to automatic Skyscraper Window Cleaning System (ASWCS) aims at providing a risk- free and more automated solution for the problem of cleaning glass-windowed high-rise buildings. It consists of a rollers-based moving platform suspended by a motorized pulley from the top of the building. The cleaning is done with the help of a motor-driven cleaning roller brush and water spraying system provided on the platform. A. Description of the cleaning module The device generally comprises a metal, plastic, polymer, or composite frame and a rotating brush. In this example, the frame is formed of a steel alloy. The metal frame comprises a plurality of tubular sections that are bolted, welded, or fastened together via typical means to form the shape. Referring to the device more specifically, the automated window washing apparatus generally comprises a frame assembly, the main brush, an optional side brush, and a IJTSRD43683 International Journal of Trend in Scientific Research and Development (IJTSRD) @ www.ijtsrd.com eISSN: 2456-6470 @ IJTSRD | Unique Paper ID – IJTSRD43683 | Volume – 5 | Issue – 4 | May-June 2021 Page 1626 shroud enclosing approximately half of the diameter of the main brush from end to end.

After the drawing, the three-dimensional model of the semi- automatic glass cleaning machine was drawn in Solid Works. Each part has been drawn separately and assembled. While designing a glass cleaning machine, some assumptions are considered which is standard for their parts. Safe design for this machine by calculating the dimensions of each part and considering formulations. Material selection based on availability, durability, cost, and ease of fabrication were also considered. The conceptual design is shown in Fig 1. FIGURE 1 Conceptual design B.
