[0033] Example:
[0034] Please refer to Figure 1-Figure 5The present embodiment provides a motor operation status monitoring device, comprising: a mounting assembly detachably connected to the motor, the mounting assembly comprising a positioning ring 1 and a locking member 2, the positioning ring 1 is used to be sleeved on the motor, the positioning ring 1 is provided with an adjustment port (not marked in the figure), and the locking member 2 is arranged on the adjustment port; a monitoring assembly, the monitoring assembly comprising a temperature monitoring member and a vibration monitoring member, the temperature monitoring member comprising a base 4 and a temperature measuring head 3, the base 4 is arranged on the positioning ring 1, the temperature measuring head 3 is arranged on the base 4, and the detection end of the temperature measuring head 3 is abutted against the outer wall of the motor, and the vibration monitoring member is arranged on the side of the base 4 away from the temperature measuring head 3.
[0035] In this embodiment, the above-mentioned mounting assembly is used to fix the entire monitoring device on the outer surface of the motor. Specifically, the above-mentioned positioning ring 1 is used to be sleeved on the outer wall of the motor, and the positioning ring 1 is fixed to the outer surface of the motor through the locking member 2. The above-mentioned adjustment port is used to adjust the tightness of the positioning ring 1 to improve the stability of the installation of the mounting assembly.
[0036] In this embodiment, the monitoring component is used to obtain the motor running state parameters, the temperature monitoring component is used to obtain the temperature parameters of the motor running in real time, and the vibration monitoring component is used to obtain the vibration parameters of the motor in real time. The base 4 is used to fix the temperature monitoring component on the positioning ring 1. When the motor moves, the monitoring component vibrates with the vibration of the motor, so that the vibration monitoring component can obtain the vibration parameters of the motor when it is running. The temperature monitoring component is kept in contact with the outer wall of the motor, and the temperature data of the motor surface can be directly obtained, and the data obtained is more accurate.
[0037] Please refer to Figure 1 , Figure 3 and Figure 4 In some implementations of this embodiment, the vibration monitoring component includes a housing 6, a vibration sensor 5 and a control module 7. The vibration sensor 5 and the control module 7 are both arranged in the housing 6, and the vibration sensor 5 and the control module 7 are connected.
[0038] In this embodiment, the housing 6 is used to install and fix the vibration monitoring component, so as to protect the vibration monitoring component and increase its service life. Specifically, the vibration sensor 5 uses a mechanical receiving component to receive the vibration signal from the object to be measured, and obtains vibration data through mechanical quantities such as displacement, velocity or acceleration. Then, through the electromechanical conversion component, the mechanical quantity is converted into an electrical signal, usually in the form of voltage or current, to facilitate subsequent processing and analysis. The control module 7 is used to process the acquired electrical signal, thereby converting the electrical signal into vibration data output.
[0039] Preferably, the control module 7 is a single chip microcomputer, which is called a single chip microcontroller or a single chip microcomputer, and is an integrated circuit chip. It uses very large scale integrated circuit technology to integrate a central processing unit (CPU) with data processing capabilities, random access memory (RAM), read-only memory (ROM), multiple I / O ports and interrupt systems, timer / counter and other functions (may also include display drive circuits, pulse width modulation circuits, analog multiplexers, A / D converters and other circuits) on a silicon chip.
[0040] Please refer to Figure 3 and Figure 4 In some implementations of this embodiment, a power supply 8 is disposed in the shell 6 , and the power supply 8 is connected to the control module 7 .
[0041] In this real-time example, the power supply 8 is used to continuously deliver electric energy to each electrical appliance, so as to facilitate the continuous operation of each electrical appliance and the continuous acquisition of motor movement parameters.
[0042] Please refer to Figure 1 and Figure 3 In some implementations of this embodiment, a heat dissipation hole 9 is provided on the shell 6 .
[0043] In this embodiment, the heat dissipation holes 9 are used to dissipate the heat in the housing 6 to avoid malfunctions caused by poor heat dissipation, thereby improving the performance of electrical appliances inside the housing 6 .
[0044] Please refer to Figure 1-Figure 4 In some implementations of this embodiment, the shell 6 includes a bottom groove 601 and a cover plate 602, the bottom groove 601 is arranged on the base 4, the cover plate 602 is covered at the mouth of the bottom groove 601, and the bottom groove 601 and the cover plate 602 are connected by multiple screws.
[0045] In this embodiment, the bottom groove 601 and the cover plate 602 are fixed by screws to form a housing 6 structure to form a closed space for installing the control module 7 and the power supply 8 equipment.
[0046] Please refer to Figure 1 , Figure 3 and Figure 4 In some implementations of this embodiment, a prompt element 10 is provided on the cover plate 602 , and the prompt element 10 is connected to the control module 7 .
[0047] In this embodiment, the prompt element 10 is used to issue a prompt message when the temperature data obtained by the temperature monitoring device and the vibration monitoring device exceeds a preset value. The user can repair or replace the motor at that location according to the prompt message to improve the safety of the motor.
[0048] Preferably, the prompt element 10 is an audible and visual alarm, which mainly relies on two signals, sound and light, to sound an alarm. It has a built-in sound generator and light source, and when an alarm event occurs, it triggers a control circuit to activate these components. The audible and visual alarm can quickly emit sound and flash signals when an alarm event occurs to alert people. This timely warning helps people take quick action to avoid or reduce potential losses or injuries.
[0049] Please refer to Figure 1 and Figure 5 In some implementations of the present embodiment, the temperature measuring head 3 includes a guide cylinder 301, a temperature sensor 303 and a push spring 302, the guide cylinder 301 is arranged on the base 4, one end of the push spring 302 is fixed on the base 4, and the push spring 302 is located in the guide cylinder 301, and the temperature sensor 303 is arranged at the end of the push spring 302 away from the base 4.
[0050] In the present embodiment, the guide cylinder 301 is fixed perpendicular to the base 4, and is used for positioning the push spring 302 and guiding the movement of the temperature sensor 303. It should be noted that when the rotating shaft of the motor moves at high speed, the motor itself will vibrate. Motor vibration is a common phenomenon, which may be caused by various factors such as electromagnetic, mechanical, ventilation and installation. These vibrations may not only affect the normal operation of the motor, but also interfere with the surrounding environment. The temperature sensor 303 is pushed to the surface of the motor by the push spring 302, so that the temperature sensor 303 is fully in contact with the motor, and the damage of the temperature sensor 303 is avoided when the high-frequency vibration or the vibration amplitude is too large, thereby improving the service life. When the vibration amplitude of the motor exceeds the preset value, the prompt element 10 emits a sound and a light signal to warn the user to avoid motor overload and damage to the motor.
[0051] Please refer to Figure 1 In some implementations of the present embodiment, an anti-skid pad (not shown in the figure) is provided on the positioning ring 1, and the anti-skid pad is located on a side of the positioning ring 1 attached to the outer side wall of the motor.
[0052] In this embodiment, the anti-skid pad is used to isolate the positioning ring 1 from the motor. When the motor vibrates, the anti-skid pad effectively increases the friction between the motor and the positioning ring 1 to prevent the anti-skid pad from falling off, which can greatly improve the stability during use.
[0053] When in use, the positioning ring 1 is sleeved on the motor, and the positioning ring 1 sleeved on the outer wall of the motor is locked and fixed by the locking member 2. When the locking member 2 is fixed, the temperature sensor 303 abuts against the outer surface of the motor, and the temperature sensor 303 compresses the push spring 302, so that the push spring 302 is in a compressed state. The temperature sensor 303 can obtain temperature data in real time; when the motor movement generates vibration, the vibration sensor 5 obtains vibration data in real time; if the output temperature data or vibration data exceeds the preset value, the prompt element 10 sends out a sound signal and a light signal to prompt the maintenance person to deal with it in real time.
[0054] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
