Description

A mobile automatic cleaning device for central air-conditioning surface cooler

technical field

The invention relates to a cleaning device, in particular to an automatic cleaning device for a surface cooler of a central air conditioner.

technical background

The air conditioner surface cooler uses chilled water to cool the air flowing through the heat exchange fins outside the tube, and sends the cooled air to the place of use through the fan. During the operation of the air conditioner, the dust inhaled through the return air system will stick to the copper tubes and fins of the surface cooler to form hard lumps of dirt, resulting in a decrease in the air supply volume and heat exchange efficiency of the air conditioner. If you use conventional cleaning methods, it is difficult to achieve the desired effect due to the special shape of the surface cooler surface; if you use a high-pressure water gun to wash, the high pressure will easily cause the fins to collapse or even deform, resulting in a decrease in the heat transfer efficiency of the air conditioner after cleaning; pressure Small ones can only clean the stains that are easy to fall off on the surface, and the purpose of cleaning cannot be achieved at all. If it is cleaned with a special cleaning agent, the cleaning cost is high, and a special cleaning tank needs to be made, and the cleaning agent is easy to cause corrosion to the fins or copper tubes of the surface cooler. In addition, traditional manual cleaning, chemical cleaning, and physical cleaning of surface coolers have accidental electric shocks, falling from high altitudes, chemicals that corrode the body, and cleaning efficiency is very low.

Contents of the invention

The purpose of the present invention is to design and provide a mobile automatic cleaning device to solve the problems in the prior art.

The present invention adopts following technical scheme:

A mobile automatic cleaning device for a central air-conditioning surface cooler. It consists of a moving device, a liquid spray system, a cleaning device, and a moving limit electric control system.

The moving device is composed of a trapezoidal screw, a lifting platform, a nut, a worm gear reducer, a vertical guide rail, a horizontal guide rail, and a mobile trolley. The operation of the worm gear reducer drives the screw to rotate, and the nut installed on the lifting platform rotates with the screw to realize the vertical movement of the lifting platform on the vertical guide rail. The mobile device moves horizontally by moving the trolley.

The liquid spray system is composed of a high-pressure pump, a connecting hose, a liquid spray pipe and a liquid storage tank. One end of the liquid spray pipe is connected with a hose, and the other end is equipped with a spray head. The liquid spray pipe is installed on the lifting platform, and the chemical cleaning agent spraying and water flushing of the surface cooler are realized through the mobile device.

The cleaning device is composed of a brush roller, a bearing seat and a servo motor. The cleaning is installed on the lifting platform, powered by the motor, driving the brush roller to rotate, and cleaning the dirt and filaments on the surface of the aluminum fins in the surface cooler.

The moving limit electric control system is composed of a vertical limit switch, a horizontal limit switch and electric control elements.

Lifting platform vertical movement limit control mode: When the induction iron installed on the lifting platform is close to the limit switch, the motor of the worm gear reducer reverses, the screw reverses, and the nut on the screw drives the lifting platform to move in the opposite direction.

The horizontal movement limit control mode of the mobile device: when the iron stopper on the lifting platform is close to the lower limit switch on the vertical guide rail, the motor of the mobile trolley is energized to run, driving the mobile device to move horizontally, and the movement is realized through the horizontal limit switch installed on the horizontal guide rail The horizontal movement limit and steering of the cleaning device.

The advantages of the technical solution of the present invention are mainly reflected in that the dust accumulated on the surface of the surface cooler of the central air conditioner can be effectively cleaned, especially the dust accumulated in the gaps of the fins of the surface cooler can be cleaned by the brush roller. The device has the characteristics of convenient operation, simple structure, few failures and high working efficiency.
