Abstract

Abstract This invention is related to the quadcopter, which can be controlled remotely. The purpose of designing this quadcopter is for aloft work, specifically, for cleaning the glass for mansions. The invention consists of four parts, fuselage, rotor wing, mechanical arm, and a remote ground station. The rotor-wing has four brushless motors, which are in the shape of a cross. It provides quadcopter the force of flight, vertical take-off, to hovers and other capabilities. The fuselage contains a control system, massage transition ability with the remote control. The mechanical arm provides the quadcopter the function to clean the glass. The remote ground station makes the quadcopter can be controlled in a distance. The invention can be widely used in the cleaning of the outer glass of buildings, with very little limitation Figure Figure2

TITLE

The quadcopter for cleaning the glass of buildings

FIELD OF THE INVENTION

This invention is related to the quadcopter, which can be controlled remotely. The purpose of designing this quadcopter is for aloft work, more specifically, for cleaning the glass for buildings.

BACKGROUND OF THE INVENTION

In recent years, coupled with the rapid development of the economy is the construction of numerous buildings which is high and covered full of glass. The cleaning of the glass is a big deal for those buildings, and this is obligatory in some countries since it is ruled by laws.

Now, there are two mainstream methods for cleaning the glass. The first method is by “Spiderman”, they suspend themselves in the outside of the window by using rope, and this method is flexible, convenient, and low priced. But, this method is extremely dangerous and high-challenge for the “Spiderman” The second method this by using the window cleaning machine. The use of this kind of machine can avoid the danger for workers since they will not suspend themselves in the outside of the window. On the hand, the demerit of this method is considerable, first, the designer must consider the installation space for the machine while designing the building. Second, the price of a window cleaning machine is expensive, around 15 thousand US dollar.

In order to solve those demerits, this invention has been designed. The quadcopter is flexible since it can fly easily and it can hover; it is low cost since it has a simple

2020100047 10 Jan 2020 structure and inexpensive components; it is safe since it only needs people to control it by using a remote control. So, it nearly solves all the problems of the two methods that have been mentioned.

SUMMARY

In order to achieve the goal, cleaning the glass of buildings, the technical scheme used in the invention is as follows.

The invention is based on a mature aircraft, namely, the quadcopter, which can achieve Fly upright, hover, etc. It provides the invention of the platform for cleaning windows. Also, a three-degree-of-freedom mechanical arm is added directly in front of the fuselage for the purpose of cleaning the glass.

In the inside of the fuselage are the main control panel, which is a SCM, the Wi-Fi module, the ultrasonic module, the camera, the water tank, the water pump and the air pump; the rotor wing consists of four brushless motor and electric speed regulator; the mechanical arm has three steeping motor; the remote ground station has a Wi-Fi module and a screen.

The signal relationship inside the fuselage:

The main control panel sends the ultrasonic module signals and the ultrasonic module send the main control panel the time used between the emission and the reception of the ultrasonic wave back in order to calculate the space between the glass and the quadcopter; the main control panel receives the signal from the camera, Wi-Fi module; the main control panel sends the water pump and the air pump signal in order to drive them to pump detergent and air.

The relationship between the fuselage and the remote ground station:

All signals for driving all the motors are sent by the remote ground station to the main control panel, specifically, the running of the two pumps, the flying altitude of the quadcopter and the gesture of the mechanical arm; the signal that the main control panel receives from the camera will be sent to the remote ground station and will be shown on the screen. All the signal transition between them are through the two Wi-Fi modules installed in both the main control panel and the remote ground station.

The relationship between the fuselage and the rotor wing:

The main control panel controls the four brushless motor through the four electric speed regulator.

The relationship between the fuselage and the mechanical arm:

The main control panel controls the three stepping motor through the driver board.

The description of the mechanical arm:

The front end of the mechanical arm is shaped as a drawknife, which can be easily removed from the mechanical arm, for the purpose of replacement and cleaning of the drawknife, also, it has several pores for the purpose of spray air and detergent. The end of the mechanical arm which is connected with the quadcopter has three stepping motors in order to achieve the three degrees of freedom movement of the mechanical arm.

DESCRIPTION OF THE PREFERRED EMBODIMENT

The arm and tank is a kind of extra device to UAV. This means these cleaning suit can be set on most of the middle size UAV, which makes the invention very convenient. The figure of the arm has shown on drawing fig 3.

The arm is designed to be three-DOF of the robot arm, and the front part is disconnected-type with a scraping shape. This main idea of this design is to ensure the efficiency of windows cleaning as the knife can be replaced handily by a more edged one.

There are two micro air pumps inside of the tank with tubes connecting the peak of the arm. The tank is divided into two areas that one is the storage of liquid and another part is full of air with a single pump in both part, so it can spray air or liquid alternatively. The things sprayed would straightly come out from the front of the arm by the track of tubes. (The tubes is made by soft plastics which make it more flexible.) The arm is set at the bottom of the UAV, an ultrasonic fault detection unit is just at top of it, which is shown in fig 1, and this unit is helpful when the arm is working by calculating a more accurate distance assumption than human eyes. The arm would find appropriate place automatically with that aid.

A camera is at the top of the UAV in order that the operator can find the untidy region

2020100047 10 Jan 2020 approximately and also check the effect of working.

The arm is controlled by an individual remote control, which has a rocker on itself. The remote control of UAV has a screen to receive the digital from the camera. Example 1

First, the operator uses the remote control of UAV to find the working area with the help of the figure shown on the screen. As the UAV closing to the windows, the arm would change its angle of joint to ensure the arm confirm to the windows under the digital of the ultrasonic detector. Then the operator uses the rocker to make the arm to clean the window, before this operator may use two pumps to spray air and water in order. The UAV may fly to another place when the operator thinks the windows of this area has been tidy enough. The operator should control the UAV to fly back to where he or she is when the task has been finished.
