[0013] A method for using an intelligent monitoring system for air compressor intake status includes the following steps: 1) Install the flange on the outside of the air inlet of the air compressor with bolts, then install the detector on the air compressor with bolts, and then connect the monitor to the sensor group, sensor, motor 1, motor 2, motor 3, air pump and discharge valve through wires, and connect the monitor to the external power supply; 2) Turn on motor 1, which drives the movable block up and down through the screw rod to adjust the height of the sensor to the inside of the air inlet of the air compressor; 3) Turn on motor 2, which pushes the screw sleeve through the screw rod. The screw sleeve drives the sensor to the inside of the air inlet on the air compressor under the limit of the support sleeve.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. When using the air compressor intake status intelligent monitoring system, the flange is installed on the air intake of the air compressor through the sealing ring and bolts, and then the motor 1 is turned on. The motor 1 drives the movable block up and down through the screw rod so that the sensor can be aligned with the inner side of the air intake of the air compressor. Then the motor 2 is turned on. The motor 2 pushes the screw sleeve to move on the inner side of the support sleeve through the screw rod so as to push the sensor to the inner side of the air intake of the air compressor. When the air compressor is working, the filtered clean air is passed into the inner side of the air compressor through the inlet pipe, and the flow rate, temperature, humidity and air pressure of the air are monitored through the sensor group, and the incoming air is monitored through the sensor. The flow rate in the air compressor is monitored. When there is a difference between the two flow rate data, it means that there is an air leak at the flange connection, which can prompt personnel to quickly seal the flange to prevent unfiltered air from entering the inside of the air compressor, avoid dust in the air from damaging the air compressor, and ensure the safety of the air compressor. At the same time, the blowing of the air flow and the vibration generated by the operation of the air compressor enable the hydraulic oil in the rubber sleeve to push open the pressure relief valve and circulate through the connecting pipe, and perform shock absorption through the rubber sleeve and spring, and damping through the pressure relief valve, which greatly reduces the vibration of the sensor and ensures the safety of the sensor.

[0015] 2. When the air compressor intake status intelligent monitoring system is in use, the air enters the inner side of the mesh cover and is filtered through the filter cartridge, and the impurities in the air are filtered on the outer side of the filter cartridge. When the air pressure monitored by the sensor group drops, the monitor turns on motor three through the controller. Motor three drives the connecting plate through the rotating rod, and the connecting plate drives the screw plate to scrape the filtered impurities on the filter cartridge and scrape the impurities to the inner side of the inner cylinder. Under the spiral push and extrusion of the screw plate, the impurities are pushed from between the inner cylinder and the filter cartridge to the inner side of the discharge pipe, and then discharged to the outside through the discharge valve, thereby effectively cleaning the filter cartridge, avoiding impurities clogging the outside of the filter cartridge, ensuring smooth air intake of the air compressor, and reducing the air intake energy consumption required for the operation of the air compressor.

[0016] 3. When the air compressor intake status intelligent monitoring system is in use, when the motor 3 drives the screw plate through the rotating rod and the connecting plate to clean the outer side of the filter cartridge for a period of time, if the air pressure monitored by the sensor group is still low, it means that very small dust is blocking the inner side of the filter hole in the filter cartridge. Then turn on the air pump, the air pump generates suction on the ferrule, and the ferrule generates suction on the through cavity in the screw plate through the rotating rod and the connecting plate, and generates suction on the filter hole in the filter cartridge through the suction port, so that the tiny dust blocking the filter hole in the filter cartridge is sucked into the through cavity in the screw plate. The inner side of the cavity, and with the rotation of the screw plate, all the filter holes on the filter cartridge are sucked into the inner side of the ferrule through the screw plate, the connecting plate and the cavity in the rotating rod in turn, and then pumped to the inner side of the filter cover by the air pump through the blowpipe. The airflow in the blowpipe blows the fan blades, and the fan blades drive the scraper to scrape the inner wall of the filter cover, reducing the blockage of the filter cover, ensuring the suction rate of the air pump, and then ensuring the cleaning effect of the filter holes of the filter cartridge, ensuring the filtration rate of the filter cartridge, and then ensuring the air intake rate of the air compressor.

At the same time, the blowing of the air flow and the vibration generated by the operation of the air compressor enable the hydraulic oil in the rubber sleeve 13 to push open the pressure relief valve 16 and circulate through the connecting pipe 15, and perform shock absorption through the rubber sleeve 13 and the spring 14, and perform damping through the pressure relief valve 16, which greatly reduces the vibration of the sensor 7, ensures the safety of the sensor 7, and the air After entering the inner side of the mesh cover 22, it is filtered through the filter cartridge 23, and the impurities in the air are filtered on the outer side of the filter cartridge 23.

The connecting plate 30 drives the screw plate 27 to scrape the filtered impurities on the filter cartridge 23 and scrape the impurities to the inner side of the inner cylinder 24. Under the spiral pushing and squeezing of the screw plate 27, the impurities are pushed from between the inner cylinder 24 and the filter cartridge 23 to the inner side of the discharge pipe 25, and then discharged outwardly through the discharge valve 26, thereby effectively cleaning the filter cartridge 23, avoiding impurities clogging the outer side of the filter cartridge 23, ensuring the smooth intake of the air compressor, and reducing air pressure. The air intake energy consumption required for the operation of the compressor is determined. After the motor 3 29 drives the screw plate 27 to clean the outer side of the filter cartridge 23 through the rotating rod 31 and the connecting plate 30 for a period of time, if the air pressure detected by the sensor group 4 is still low, it means that very small dust is blocked on the inner side of the filter holes in the filter cartridge 23. Then the air pump 33 is turned on, and the air pump 33 generates suction on the ferrule 28. The ferrule 28 generates suction on the through cavity 32 in the screw plate 27 through the rotating rod 31 and the connecting plate 30, and generates suction on the filter holes in the filter cartridge 23 through the suction port 37, sucking the tiny dust blocked in the filter holes in the filter cartridge 23 into the inner side of the through cavity 32 in the screw plate 27, and as the screw plate 27 rotates, all the filter holes on the filter cartridge 23 are subjected to high-pressure suction.The tiny dust particles clogged in the filter holes of the filter cartridge 23 are sucked into the inner side of the ferrule 28 through the screw plate 27, the connecting plate 30, and the cavity 32 in the rotating rod 31. They are then pumped by the air pump 33 through the blowpipe 35 to the inner side of the filter cover 34. The airflow in the blowpipe 35 blows the fan blades 38, which drive the scrapers 36 to scrape the inner wall of the filter cover 34, reducing the blockage of the filter cover 34 and ensuring the suction rate of the air pump 33. In turn, the cleaning effect of the filter holes of the filter cartridge 23 is guaranteed, and the filtration rate of the filter cartridge 23 is guaranteed, which in turn guarantees the air intake rate of the air compressor.
