[0002] Coal mine electromechanical equipment is an important part of coal mine production. Its normal operation plays an important role in ensuring the smooth progress of coal mine production. Therefore, cleaning and maintenance are essential. Cleaning and maintenance can remove dust, oil and other impurities on the surface of the equipment, reduce the impact of these impurities on the mechanical operation and electrical transmission of the equipment, and ensure the normal operation of the equipment. Good cleaning and maintenance work can slow down the wear of the equipment, extend the service life of the equipment, reduce the operating cost of the equipment, and improve the economic benefits of the coal mine.

A sewage pipe 2 is installed on one side of the ultrasonic cleaning box 1, and a pipe cover 3 is installed on the end of the sewage pipe 2. The shaking mechanism is used to shake the ultrasonic cleaning box 1 back and forth during the cleaning process. The energy consumption collection module 4 is used to monitor the power fluctuation of the motor 12 of the shaking mechanism in real time, and generate an energy consumption fluctuation coefficient through the central processing unit in the control box 6. The dirt residue collection module 5 is used to detect the concentration of suspended particles in the cleaning liquid in real time, and generate a dirt residue variation coefficient through the central processing unit.

Therefore, the energy consumption collection module 4, the dirt residue collection module 5 and the control module 8 are not specifically limited here and can be selected according to actual needs;

[0044] During use, the components of the coal mine electromechanical equipment are placed in a special cleaning frame that matches the ultrasonic cleaning box 1, and then the cleaning frame is placed in the cleaning tank of the ultrasonic cleaning box 1, and then the ultrasonic cleaning box 1 is started for cleaning. During the cleaning process, the ultrasonic cleaning box 1 is moderately shaken by the shaking mechanism, and the central processing unit comprehensively analyzes the generated energy consumption fluctuation coefficient and dirt residue variation coefficient to generate an evaluation coefficient to determine whether the current cleaning state meets normal cleaning requirements. The evaluation coefficient is compared with the pre-set evaluation coefficient reference threshold, and the shaking mechanism and the ultrasonic cleaning box 1 working state are controlled according to the comparison result, thereby helping the cleaning liquid to enter the hidden area of the component, avoiding the shadow effect, and thus improving the cleaning effect. When the cleaning is completed, the pipe cover 3 is removed from the sewage pipe 2, and then the sewage in the ultrasonic cleaning box 1 can be discharged from the sewage pipe 2.

[0045] Among them, the shaking mechanism includes a frame 7 and a frame 8 that can move back and forth in the frame 7. The frame 8 is fixedly sleeved on the ultrasonic cleaning box 1.

Then the disc 10 will periodically push and pull the connecting rod 11, thereby driving the ultrasonic cleaning box 1 to move back and forth through the frame 8, thereby realizing the shaking of the ultrasonic cleaning box 1.

[0047] Among them, the control box 6 is installed on the side of the ultrasonic cleaning box 1 close to the motor 12, the energy consumption collection module 4 is installed on the mounting base 9 close to the motor 12, and the dirt residue collection module 5 is installed inside the ultrasonic cleaning box 1;

The water inlet end of the water pump 18 is connected to the water tank 17 through a water outlet pipe 21, and the water outlet end of the water pump 18 is connected to a tee pipe 19. A water spray pipe 20 is fixed through the side of the ultrasonic cleaning box 1 close to the water tank 17, and both ends of the water spray pipe 20 are respectively connected to the tee pipe 19;

[0052] During use, after the sewage is discharged through the sewage pipe 2, dirt will remain at the bottom of the cleaning tank of the ultrasonic cleaning box 1. At this time, the water pump 18 can be started, and the water in the water tank 17 is pumped into the three-way pipe 19 and then into the water spray pipe 20 through the water pump 18. The water spray pipe 20 flushes the cleaning tank, and then the sewage is discharged from the sewage pipe 2, thereby facilitating the cleaning of the cleaning tank.

[0057] Coefficient calculation: The central processing unit calculates the energy consumption fluctuation coefficient, dirt residue variation coefficient and evaluation coefficient ;

[0058] Among them, the energy consumption fluctuation coefficient reflects the difference between the actual power fluctuation of the motor 12 when the shaking mechanism shakes the ultrasonic cleaning box 1 at the initial moment within the time T and the actual power fluctuation of the motor 12 when the shaking mechanism shakes the ultrasonic cleaning box 1 at different moments. The greater the fluctuation, the more severe the load fluctuation of the motor 12 is, which does not meet the normal cleaning requirements and requires adjustment of the cleaning intensity;

The larger the value, the faster the dirt removal rate and the higher the cleaning efficiency, which satisfies normal cleaning and does not require adjustment.

[0065] The generation logic of the dirt residue variation coefficient is:

[0066] S1. The dirt residue collection module 5 is used to obtain the actual suspended particle concentration in the cleaning liquid at different times during the T time when the shaking mechanism shakes the ultrasonic cleaning box 1.
