Life-span.If general temperature protective device is reinstalled, it is necessary to damage ground or erection bridge in scene, very inconvenient.
Utility model content
The purpose of this utility model is to provide a kind of novel portable motor temperature controlling alarm, can facilitated, reliably
Ground is arranged on motor, without the device structure that destorys the scene, and when motor temperature is too high and alarm, realizes the height to motor
Temperature protection.
To achieve the above object, the technical solution adopted in the utility model is；
A kind of novel portable motor temperature controlling alarm, including temperature controller, alarm and temperature measuring equipment, described survey

The alarm signal input of alert device, described temperature measuring equipment includes temperature sensor and its mounting assembly, described mounting assembly
Including heat conduction bar, heat conduction inner tube, heat conduction outer tube and compression spring, described temperature sensor is arranged in heat conduction inner tube, temperature
The thermometric end of sensor and the bottom connection of heat conduction inner tube, described heat conduction outer tube are set in outside heat conduction inner tube, heat conduction outer tube
Lower end closed and be fixedly connected with heat conduction bar, the outer wall of heat conduction inner tube is provided with the first back-up ring, and the inwall of heat conduction outer tube is provided with
Second back-up ring, the upper end of described compression spring connects the first back-up ring, and the lower end of compression spring connects the second back-up ring, heat conduction inner tube
Bottom and the distance between the bottom of heat conduction outer tube matched with the reduction length of compression spring.
The top of described heat conduction outer tube is arranged with annular permanent magnnet.
Described heat conduction strip adoption metal material, the thickness of heat conduction bar is less than 0.5mm.
The alarm signal of described alarm output includes optical signal and the voice signal of three kinds of intensity.
The utility model obtains motor winding temperature using temperature sensor and its mounting assembly, and in motor winding temperature
Alarm is controlled to send alarm signal by temperature controller when too high, it is to avoid motor is because a variety of causes causes temperature to raise and damages
Ruin；The utility model is led by the way that temperature sensor is arranged in the heat conduction inner tube of mounting assembly, and using compression spring realization
Hot inner tube and the forced contact of heat conduction outer tube, greatly reduce the impact that temperature sensor is subject to by motor oscillating, reduce temperature
Spend the fault rate of sensor；The utility model utilizes heat conduction bar by setting heat conduction bar in the heat conduction outer tube lower end of mounting assembly
Contact with machine winding obtains real time temperature, and substantially overcoming that machine winding gap is narrow and small can not temperature sensor mounted difficulty
Topic, reduces the difficulty of motor temperature detection work.
Brief description of the drawings
Fig. 1 is the former road figure of circuit of the present utility model；
Fig. 2 is temperature sensor described in the utility model and its structural representation of mounting assembly.
Embodiment
As shown in figure 1, novel portable motor temperature controlling alarm described in the utility model, including temperature controller, alarm
Device and temperature measuring equipment, the temperature signal output end of temperature measuring equipment connect the temperature signal input of temperature controller, the alarm of temperature controller
Signal output part connects the alarm signal input of alarm.The alarm signal of alarm output in the present embodiment is believed including light
Number and three kinds of intensity voice signal, correspondingly, three different size of temperature thresholds of setting in temperature controller.If temperature measuring equipment is defeated
The motor winding temperature gone out is higher than some temperature threshold that temperature controller is set, then temperature controller control alarm sends light alerting signal
And the audible ringing signal of respective strengths, remind staff to handle in time, greatly reduce motor because temperature height is not sent out
Now cause insulation ag(e)ing or the probability burnt.
As shown in Fig. 2 temperature measuring equipment of the present utility model includes temperature sensor 1 and its mounting assembly, mounting assembly bag
Heat conduction bar 2, heat conduction inner tube 3, heat conduction outer tube 4 and compression spring 5 are included, temperature sensor 1 is arranged in heat conduction inner tube 3, temperature is passed
The thermometric end of sensor 1 and the bottom connection of heat conduction inner tube 3, the lead end of temperature sensor 1 are fixed in heat conduction by rubber ring 9
The top of pipe 3.Heat conduction outer tube 4 is set in the outside of heat conduction inner tube 3, and the lower end closed of heat conduction outer tube 4 is simultaneously fixedly connected with heat conduction bar
2, heat conduction bar 2 is made of metal material, and thickness is less than 0.5mm, is inserted into the gap inside machine winding.Heat conduction bar 2 is obtained
The motor winding temperature obtained passes to heat conduction outer tube 4, the temperature detection for temperature sensor 1.
The outer wall of heat conduction inner tube 3 of the present utility model is provided with the first back-up ring 6, and the inwall of heat conduction outer tube 4 is provided with second
Back-up ring 7, compression spring 5 is set in heat conduction inner tube 3, and the upper end of compression spring 5 connects the first back-up ring 6, lower end connection second
