In industrial sites, monitoring the temperature of production equipment enables the operating state of the equipment to be assessed. For example, in the current secondary water supply pump house, generally the staff measures through hand-held type thermoscope when patrolling and examining, because the artificial mode can not realize lasting long-time operating temperature monitoring, before the motor takes place because lack of phase or short circuit etc. the motor temperature can rise, there is gas or control parameter improper in the pump body of water pump, the water pump can form the stifle and beat, water lasts at the pump inner loop, the pump body generates heat, can reach 100 degrees at most, the rubber circle above the mechanical seal that can lead to the water pump is ageing like this, the water pump leaks, life reduces. Also, if the driving control system of the secondary water supply apparatus is operated under a heavy load for a long time, the temperature rises rapidly, which causes structural deformation and a reduction in electrical life. In conclusion, it is very necessary to monitor the temperature of key components and parts such as a water pump, a frequency converter, a contactor, a pipeline, a cabinet body and the like, and the service life of equipment is prolonged and the fire risk is reduced by early warning and alarming the operation of facility equipment through the heating phenomenon.

Although the existing infrared temperature detector can realize reciprocating rotation and pitching motion of 360 degrees and detect the temperature of each device in sequence, the infrared temperature detector is limited by the structure, and after the infrared temperature detector is used for a period of time, because a detection head at the front end of the infrared temperature detector does not have a cleaning device, the detection head is possibly influenced by adhesion of dust and the like, and when a worker does not clean the device in time, the detected temperature data can be deviated. In summary, it is especially necessary to provide an infrared temperature measuring device capable of effectively ensuring the cleanliness of a probe of an infrared temperature detector and effectively detecting temperature data of each device.
