Description

Technical Field

[0001] The utility model relates to the field of mechanical and electrical equipment failure and detection, in particular to an automatic alarm device for loosening of a motor base. Background Art

[0002] The current motor base cannot detect the looseness problem in time. Looseness of the base will cause the motor vibration to intensify, affecting the motor performance and service life. Failure to detect and deal with the looseness problem in time may cause motor damage or even cause safety accidents. Temperature abnormalities cannot be detected and handled in time. Excessive temperature during motor operation will accelerate insulation aging and shorten the service life of the motor. Temperature abnormalities may also cause serious faults such as motor burnout, causing economic losses and safety hazards. There is no temperature monitoring function, and temperature abnormalities cannot be detected and handled in time. Lack of remote monitoring and data analysis capabilities, unable to grasp the motor operation status in real time, is not conducive to equipment management and maintenance, lack of historical operation data accumulation, unable to perform big data analysis and fault prediction, and unable to remotely diagnose when a fault occurs, extending downtime and increasing maintenance costs. The search of existing patents did not find any relevant patents specifically for loose base alarms. The motor base in the prior art has the following inconveniences during operation:

The looseness of the base will cause the motor vibration to intensify, affecting the motor performance and service life. Failure to detect and deal with the looseness problem in time may cause motor damage and even cause safety accidents. Therefore, there is an urgent need for an automatic alarm device for loose motor base;

[0004] 2. Temperature abnormalities cannot be discovered and handled in time. Excessive temperature during motor operation will accelerate insulation aging and shorten the service life of the motor.

Therefore, a motor base alarm device that can monitor motor temperature is urgently needed;

[0005] 3. Lack of remote monitoring and data analysis capabilities, unable to grasp the motor operating status in real time, not conducive to equipment management and maintenance, lack of historical operating data accumulation, unable to perform big data analysis and fault prediction, unable to remotely diagnose when a fault occurs, extending downtime and increasing maintenance costs, so there is an urgent need for a motor base that can perform remote data collection.

[0028]

[0029] By comparing the above table, it can be seen that compared with the traditional motor base, the utility model uses the vibration monitoring sensor to convert mechanical vibration into electrical signal output by using the piezoelectric effect or capacitance principle. It can timely capture abnormal vibration caused by loose base or other faults to achieve early warning. It is more timely, accurate and objective than simple manual inspection. By using the temperature monitoring sensor, the temperature is converted into electrical signal output by using the principles of thermal resistors, thermocouples, etc. It can accurately detect the temperature change of the motor and timely discover the hidden danger of overheating. It is more continuous and timely than manual regular detection, avoiding omissions. Relying on sensors to monitor vibration offset and temperature can extend the service life of the equipment by 60%. By using the data transmission module, wireless communication technology is used to transmit the collected data to the remote end. It realizes seamless connection between the equipment and the monitoring center, making fault diagnosis and maintenance decisions more efficient. It breaks the traditional passive maintenance mode, improves the intelligent level of equipment management, and relies on this module to increase the equipment maintenance speed by 60%.

[0030] The vibration monitoring sensor described in the utility model uses the QG series acceleration sensor produced by Honeywell. The piezoelectric ceramic structure of this sensor has fast response, high sensitivity, wide measurement range, small size, light weight, convenient installation, and strong anti-vibration and impact ability. It has many advantages when used in this equipment. When the motor is running, if the base is loose, it will cause abnormal vibration of the whole machine. The vibration sensor can keenly detect this vibration change, so as to realize the timely discovery and alarm of the loose fault, and avoid further expansion of the fault and cause greater losses. Unlike traditional manual regular inspections, the vibration sensor can realize online and continuous monitoring of the motor base without missing any inspections. Once an abnormality is detected, an alarm can be triggered immediately to improve the timeliness of fault discovery. The vibration sensor outputs quantized electrical signal data, which can accurately analyze parameters such as vibration amplitude and frequency, rather than subjective judgment. This provides an objective basis for fault diagnosis and maintenance decisions. The vibration data collected by the sensor can be input into the intelligent system, and through big data analysis and machine learning algorithms, intelligent predictive maintenance such as fault mode recognition and remaining life prediction can be realized to improve the accuracy and efficiency of maintenance. Timely detection of faults can prevent them from expanding and causing greater losses; no manual regular inspection is required, reducing maintenance labor costs; intelligent maintenance improves maintenance efficiency, reduces unplanned downtime, and thus reduces overall maintenance costs.
