With the foregoing drawings in mind, certain embodiments of the disclosure have been shown and described in more detail below. These drawings and written description are not intended to limit the scope of the disclosed concepts in any way, but rather to illustrate the concepts of the disclosure to those skilled in the art by reference to specific embodiments.
Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
In a possible application, when a series of problems occur in the bearings of the motor, such as severe wear of the balls inside the bearings, reduction of the lubricating oil, etc., the resistance at the position where the output shaft contacts the bearings is increased, which leads to a temperature increase. Therefore, the current state of the bearing can be determined by detecting the temperature condition near the bearing, if the temperature exceeds the temperature threshold value, the problem of the bearing is indicated, and if the temperature does not exceed the temperature threshold value, the good state of the bearing is indicated.
In the related technology, usually, when a technician walks to a certain motor during field patrol, the sound emitted by the motor during current operation is different from the sound emitted by the motor during normal operation, so that the problem of the bearing can be predicted, and then the temperature near the bearing is measured by further using a portable temperature measuring instrument, if the temperature exceeds a temperature threshold value, the problem of the bearing can be determined, and the motor can be disassembled, the bearing is replaced or lubricating oil and the like are added.
Therefore, technicians need to carry the temperature measuring instrument with the temperature measuring instrument in the process of field inspection, if the technicians forget to carry the temperature measuring instrument, the current state of the bearing is still judged through auditory experience, and therefore the flexibility of measuring the temperature near the bearing is poor in the related technology.
The embodiment of the present application provides a temperature alarm installed on a motor, which can solve the above problems, and as shown in fig. 1, the temperature alarm may include a housing 1, a control part 2, a detection head 3, and an alarm part 4, wherein: the control component 2 and the alarm component 4 are both positioned in the shell 1, the probe 3 extends out of the shell 1, and the probe 3 is used for being attached to a temperature detection position on the motor, which is close to the bearing; the control component 2 is respectively electrically connected with the detecting head 3 and the alarm component 4 and is used for controlling the alarm component 4 to generate alarm information when detecting that the temperature received from the detecting head 3 exceeds a preset temperature threshold value.
In practice, the temperature alarm may be mounted on the motor, for example, on the housing of the motor. Specifically, the housing 1 of the temperature alarm may be fixed to the housing of the motor by screws, or the housing 1 of the temperature alarm may be welded to the housing of the motor. Wherein the probe head 3 is used for detecting the problem of an object in contact with the probe head, and correspondingly, the probe head 3 can be attached to the temperature detection position of the motor close to the bearing.
Wherein the temperature detection position is a position on the motor housing near the bearing.
In practice, the inner race of the bearing fits over the output shaft of the motor and the outer race of the bearing is fixed to the housing of the motor so that the bearing is located within the housing of the motor and not shown outside, so that the probe 3 cannot directly contact the bearing. However, the probe 3 may be located as close to the bearing as possible, and accordingly, the probe 3 may be located at a position corresponding to the bearing on the housing of the motor, that is, the probe 3 may be attached to the temperature detection position.
Wherein, for realizing that detecting head 3 and temperature detect the position and laminate mutually, it can be correspondingly that, detecting head 3 can have magnetism, and the shell of motor is made by metal usually, so detecting head 3 can adsorb in temperature detect position department, and then can measure the temperature of temperature detect position department.
The temperature detection range of the probe 3 may be-50 to 110 ℃.
In implementation, the probe 3 may transmit the measured temperature to the control unit 2, the control unit 2 determines the received current temperature after receiving the temperature transmitted by the probe 3, and if the current temperature exceeds a preset temperature threshold, the alarm unit 4 may transmit an alarm signal, and after receiving the alarm signal transmitted by the control unit 2, the alarm unit 4 may generate an alarm message.
Based on the above, the motor is provided with the temperature alarm, and the probe of the temperature alarm is attached to the position of the housing of the motor corresponding to the bearing, that is, the probe of the temperature alarm is attached to the temperature detection position of the motor. Temperature alarm can carry out real-time temperature measurement to bearing position like this, and when the temperature surpassed and predetermine the temperature threshold value, this temperature alarm can also send alarm information to reach the effect of reminding the technical staff. Compared with the prior art in which the current working condition of the bearing is judged by hearing, the method obviously can improve the judgment result and reduce the possibility of misjudgment.
Optionally, the alarm information sent by the alarm component 4 is related to a specific structure of the alarm component 4, for example, the alarm component 4 may be an indicator light, and the alarm information may be a flashing of the indicator light, where the indicator light may be an LED (light emitting Diode) light, and specifically may be a 12 volt 3 watt LED light. For another example, the alarm part 4 may be a buzzer, and accordingly, the alarm information may be a sound of the buzzer.
In the present embodiment, the specific structure of the alarm unit 4 is not limited as long as information that attracts the attention of a technician can be generated.
Optionally, in order to enable the technician to know the current temperature state of the motor, correspondingly, the temperature alarm may further include a display screen, and the display screen is mounted on the housing 1; the control component 2 is electrically connected with the display screen, and the control component 2 is also used for controlling the display screen to display the temperature received from the probe 3.
The display screen can be a digital temperature display screen, and the display screen can be a touch display screen and has a touch function, so that a technician can set a preset temperature threshold value on the display screen.
In practice, the probe 3 can send the measured temperature to the control part 2, and after the control part 2 receives the temperature, the display screen can be controlled to display the currently received temperature, so that a technician can know the current temperature condition of the bearing conveniently.
Optionally, the motor works normally, and when the bearing state is good, the temperature at the bearing is related to the rotating speed and the working load of the motor. For example, in the zero load condition, that is, in the idling condition, the temperature in the vicinity of the bearing in the good condition is low. When the rotation speed of the motor is low, the temperature in the vicinity of the bearing in a good state is also low. The preset temperature threshold is related to the rotation speed and the work load of the motor, and the technician can adjust the preset temperature threshold according to the specific situation of the motor. For example, the display screen is a touch screen, and has a setting option of a preset temperature threshold, so that a technician can adjust the preset temperature threshold on the display screen to adapt to motors in different working states, and further, the application universality of the temperature alarm can be improved.
Optionally, as shown in fig. 2, the temperature alarm further includes a battery unit 5, and the control unit 2 and the probe 3 are electrically connected to the battery unit 5.
The battery part 5 may be a button cell battery, a storage battery, a lithium battery, or the like.
In practice, the battery part 5 is electrically connected with the control part 2, the detecting head 3, the alarm part 4 and the display screen respectively, and is used for supplying electric quantity to the control part, the detecting head 3, the alarm part 4 and the display screen.
Optionally, in order to enable a technician who operates the motor in the background to know the current temperature condition of the bearing of the motor without performing a field patrol, the temperature alarm may further include a data transmission component, and the data transmission component is electrically connected with the control component 2; and the control part 2 is also used for sending the temperature received from the probe head 3 to the temperature monitoring terminal through the data transmission part.
The temperature monitoring terminal can be a terminal in a background control room of the motor, and can also be a portable device carried by a technician.
In an implementation, the data transmission component may be a WiFi (Wireless Fidelity) component, a Wireless connection may be established between the temperature alarm and the temperature monitoring terminal through the data transmission component, and then the control component 2 may send the temperature to the temperature monitoring terminal through the data transmission component. After the temperature monitoring terminal receives the temperature of the bearing of one motor, the received temperature can be judged, and if the temperature exceeds a preset temperature threshold value, alarm information can be sent out to attract the attention of technicians.
Or the control part 2 of the temperature alarm can also send bearing abnormity information to the temperature monitoring terminal through the data transmission part. For example, when the control component 2 determines that the received temperature exceeds the preset temperature threshold, the alarm component is controlled to send alarm information, and the bearing abnormal information is also sent to the temperature monitoring terminal through the data transmission component, and the temperature monitoring terminal can send the alarm information after receiving the bearing abnormal information. Therefore, the temperature alarm can not only enable technicians who perform field inspection to know the bearing of the motor in time, but also enable technicians who do not perform field inspection to know the bearing of the motor in time.
Like this, the technical staff in time knows the bearing and after the problem appears through the temperature of bearing, can in time stop the work of motor, changes the bearing, perhaps adds lubricating oil to the bearing and handles, and then can avoid the motor to take place the locking, and the condition of burning out the motor also can further prolong the life of motor.
In the embodiment of the present disclosure, a temperature alarm is installed on the motor, and a probe of the temperature alarm is attached to a position corresponding to the bearing on the housing of the motor, that is, the probe of the temperature alarm is attached to a temperature detection position on the motor. Temperature alarm can carry out real-time temperature measurement to bearing position like this, and when the temperature surpassed and predetermine the temperature threshold value, this temperature alarm can also send alarm information to reach the effect of reminding the technical staff. Compared with the prior art in which the current working condition of the bearing is judged by hearing, the method obviously can improve the judgment result and reduce the possibility of misjudgment.
It will be understood that the present disclosure is not limited to the precise arrangements described above and shown in the drawings and that various modifications and changes may be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
