Duct cleaning robot

Abstract

The present invention relates to a duct cleaning robot developed to easily clean various types of alien substances, including dust accumulated inside a duct, before the alien substances harden on the inner wall surface and suck and remove generated dust. The duct cleaning robot ejects high-pressure air to the interior of a duct and cleans the interior using a robot electric motor car provided with wheels and controlled in a wired manner. The duct cleaning robot comprises: a robot electric motor car having at least four wheels, which are driven by an internal motor, and cameras mounted on front and rear sides, respectively; a control unit having a controller, which has a compressor and controls the robot electric motor car, and a wire and an air tube formed to control the robot electric motor car; a dust-collecting device comprising at least two cymbal-type intake tubes extending from the front of the robot electric motor car in the forward direction, a manifold for converging air, which has been taken in from the rear of the at least two intake tubes, into one space, a dust-collecting unit mounted on the rear of the robot electric motor car and provided with a filter therein, a connection tube for connecting the manifold and the dust-collecting unit, and a number of air ejection nozzles for ejecting air obliquely, in the middle of the connection tube, towards the dust-collecting unit at the rear; and an ejection device comprising at least two air ejection tubes extending from the front of the robot electric motor car in the forward direction, an air tube mounting unit, on which an end of the air tube is mounted at the rear of the robot electric motor car, an air supply conduit for splitting supplied air into at least two streams and connecting / supplying the streams to the air ejection tubes, an air discharge conduit branching off from the air supply conduit to be connected to the air ejection nozzles, an adjustment screw mounting hole extending through the air discharge conduit from the rear and having a thread formed on the inner peripheral surface thereof, and an adjustment screw mounted in the adjustment screw mounting hole such that an end of the adjustment screw adjusts air that is introduced / discharged into / from the air discharge conduit.

Description

technical field [0001] The present invention relates to a pipe cleaning robot. More specifically, it relates to a robot that can easily clean various foreign objects such as dust accumulated inside the pipe, prevent various foreign objects from stubbornly sticking to the inner wall surface, and clean by sucking the dust. Pipe cleaning robot. Background technique [0002] Usually, the ducts are used for air supply and exhaust. Therefore, various foreign matter contained in the incoming and outgoing air gradually accumulates on the ducts, accumulating over time and becoming suitable conditions for breeding various bacteria or mildew. [0003] In addition, dust or foreign matter accumulated inside the duct during ventilation or ventilation enters the room through the duct and causes respiratory diseases, which have adverse effects on the human body and become the cause of indoor air pollution. [0004] In particular, the ducts installed in the ceilings of buildings and subways...

Problems solved by technology

[0003] In addition, dust or foreign matter accumulated inside the ducts during ventilation or ventilation enters the room through the ducts and causes respiratory diseases, which have adverse effects on the human body and become the cause of indoor air pollution.

[0004] In particular, the ducts installed in the ceilings of buildings and subways supply cold air to the platform in summer, and stop using it in winter, and supply cold air to the platform again in summer. Since the dust accumulated in winter is sprayed to the tires together with the cold air, it is difficult to Causes harm to the human body and causes diseases of the circulatory system of the human body

[0005] In order to prevent the dust and other dirt accumulated in the pipeline from being sprayed on the human body to cause harm and cause diseases of the circulatory system, it is necessary to regularly remove the dust or dirt remaining inside the pipeline, but people cannot enter the pipeline for cleaning

[0006] Therefore, recently, a remote-controlled robot has been used to enter the interior of the pipeline and use a cleaning brush or spray compressed air to remove accumulated dust and foreign objects. However, this method has the problem of instantaneous re-accumulation of splashed dust and foreign objects, resulting in reduced efficiency. The problem that the camera of the robot is difficult to ensure the line of sight
