Abstract

The invention relates to a cleaning device of air condition, which comprises upper and lower horizontal guide rails, and a movable support between the beams while the upper and lower ends of said movable support have wheel bases via the roller wheel axles connecting the roller wheels; the movable support has a horizontal drive device which drives the roller wheel axles to rotate the roller wheels, therefore, the movable support can horizontally move between the upper and lower horizontal guide rails; the side of movable support opposite to the heat emission device of air conditioner is fixed with a longitudinal guide rail; and the nozzle elements driven by the longitudinal drive device on the movable support can move up-and-down along the longitudinal guide rail. The inventive nozzle is a liner nozzle whose end face has a groove through to the water injection hole, therefore, the injected water is in sheet shape to enter the slit between blades to wash the embedded dust outside the back of heat emission device, with better cleaning efficiency.

A movable frame 3 is provided between the horizontal guide rails 1, and the upper and lower ends of the movable frame 3 are each provided with a wheel seat 11, the upper and lower wheel seats 11 are each connected to a roller shaft 12 by a bearing 12-1, and a roller is fixed on the roller shaft 12 13. The rollers 13 on the upper and lower wheel seats 11 are of equal diameter and are respectively placed on the upper and lower lateral guide rails 1 to roll on the top surface of the upper and lower lateral guide rails 1. The upper and lower wheel seats 11 are each provided with anti-side wheels 15 on both sides of the roller 12 and whose axis line is parallel to the roller axis line (see image 3 ), the shaft of the anti-side wheel 15 is fixed on the wheel seat 11 and the anti-side wheel 15 is connected by a bearing. The upper and lower wheel seats 11 are also provided with two guide wheels 14 on both sides of the I-steel vertical plate 1-1 and the axis is parallel to the I-steel 1 vertical plate 1-1 (see Figures 4 to 5). The shaft 14-1 of 14 is fixed on the bracket 11-1 of the wheel base 11, and the guide wheel 14 and the shaft 14-1 are connected by a bearing.
[0035] See Figures 1 and 2, the moving frame 3 is provided with a transverse driving mechanism 2. The traverse drive mechanism 2 includes a motor 2-1 fixed on the upper part of the movable frame 3, a reducer 2-2, and a longitudinal axis 2-4 connected to the movable frame 3 through a bearing seat 2-5, a reducer 2-2 and the longitudinal axis 2-4 are connected by a cylindrical gear pair 2-3, and upper and lower bevel gear pairs 2-6 passing through the upper and lower ends of the longitudinal shaft 2-4 are connected with the roller shaft 12 at the upper and lower ends of the moving frame 3. The specifications of the upper and lower bevel gear pairs 2-6 are the same to ensure that the upper and lower roller shafts 12 on the movable frame 3 rotate at the same speed and in the same direction. The traverse driving mechanism 2 drives the roller shaft 12 to drive the roller 13 to rotate, so that the moving frame 3 is moved laterally between the upper and lower horizontal rails 1.
[0036] As shown in Figures 1 and 2, the movable frame 3 is provided with a nozzle assembly 5 and a longitudinal drive mechanism 6, and a longitudinal guide rail 4 is fixed on the side opposite to the radiator of the air cooling unit, and the longitudinal guide rail 4 is made of I-beam.
[0037] see Figure 6-7 , 9-11, the nozzle assembly 5 has a moving box 5-1. The moving box 5-1 is provided with 4 rollers 5-2. The rollers 5-2 are located on both sides of the I-steel vertical plate and the axis is perpendicular to the work The vertical plate in the word steel. The moving box 5-1 is also provided with four guide wheels 5-6 whose axis is parallel to the I-steel middle vertical plate. The four guide wheels 5-6 are respectively located on both sides of the I-steel middle vertical plate and are connected to the front and rear rollers 5- 2Interval settings. The roller shaft 5-2-1 on each roller 5-2 and the guide roller shaft 5-6-1 on each guide wheel 5-6 are all fixedly connected to the moving box 5-1, and the roller 5-2 is connected to the roller shaft 5- The 2-1 is connected by a bearing 5-2-2, and the guide wheel 5-6 and the guide wheel shaft 5-6-1 are connected by a bearing 5-6-2.
[0038] See Figures 1 and 2, the longitudinal drive mechanism 6 includes a motor and a reducer 6-1, which are above the longitudinal guide 4 and fixed on the moving frame 3, and a driving sprocket 6-2 connected to the output shaft of the reducer 6-1 , The driven sprocket 6-4 under the longitudinal guide rail 4 and connected to the moving frame 3, and the chain 6-3 connected between the driving sprocket 6-2 and the driven sprocket 6-4, the moving box 6-1 is connected in series in chain 6-3. The movable frame 3 is provided with adjustable tensioning sprocket 6-5 (see Figure 1 and Figure 8 ).
[0039] See Figures 1, 2, 12, 13. The moving box 5-1 is provided with a longitudinal water pipe 5-3, and the upper and lower ends of the longitudinal water pipe 5-3 are each provided with a horizontal branch pipe 5-4, and each horizontal branch pipe 5 At least 2 nozzles 5-5 are provided on -4, and the embodiment uses 3 nozzles. The longitudinal water pipe 5-3 is connected to the water pump through a hose 5-7.
[0040] see Picture 14 , 15, The nozzle assembly nozzle 5-5 is a linear nozzle, that is, on the end surface of the nozzle 5-5 is provided with a strip slot 5-5-2 that penetrates the water spray hole 5-5-1, and the outlet of the nozzle 5-5 The aperture d of the part is 2.6 mm, and the width h of the slot 5-5-2 is 1.2 mm. The water sprayed by the spray head 5-5 is in the shape of a sheet and can be injected into the slits between the radiator fins.
[0041] In the above-mentioned embodiment, one of the upper and lower horizontal rails 1 is provided with a travel switch 9 corresponding to the left and right dead points of the movement of the movable frame 3, and the vertical rail 4 corresponds to the upper and lower movement of the nozzle assembly 5. Each dead point is provided with a travel switch 7. A control box is arranged at an appropriate height in the lower part of the mobile frame, and control buttons are installed on the control box panel. The horizontal movement of the moving frame and the longitudinal movement of the nozzle assembly are controlled by the programmable controller (see Figure 18 ). In the programmable controller control system, buttons and travel switches are used as the input signal components of the programmable controller, and the contactor is used as the output actuator, which is used to control the motor of the transverse drive mechanism 2 and the motor of the longitudinal drive mechanism 6. Reverse and stop. There are two control methods, manual and fully automatic. Manual control is used when installation and debugging or manual control is necessary. Press the "Left" button to move the mobile rack to the left. If you press the "Left" button again, the mobile rack will stop running. Similarly, the mobile rack "Right" , Nozzle assembly "upward", nozzle assembly "downward" all operate in this way. The moving frame runs to the left and right dead points and touches the travel switch 9 and the upper and lower dead points touches the travel switch 7, and it can stop automatically. At the beginning of the fully automatic control operation, the moving frame is at the right dead center position, and the nozzle assembly is at the top dead center position, then the moving frame is 60cm to the left, and the nozzle assembly goes down → up → the moving frame is 60cm left → the nozzle assembly goes down → up until it moves After the carriage moves to the left dead center position, it returns to the right dead center position. During the running process, if you want to stop the work artificially, you can press the "Tentative" button.
