Description

Magnetic wireless temperature measuring device

Technical Field

The utility model belongs to the technical field of the temperature measurement technique and specifically relates to a wireless temperature measuring device of formula is inhaled to magnetism.

Background

The belt conveyor (belt conveyor) is used as a main force device for port transportation, and plays an extremely important role in the transportation process due to the high automation and specialization degree, the continuous operation mode and the large transportation volume operation mode. However, with the continuous aggravation of production tasks, the utilization rate of equipment is gradually improved, the belt conveyor is in a running state for a long time, and the temperature is increased due to mechanical faults such as unbalance, misalignment and abrasion of key parts such as a belt conveyor roller and the like caused by vibration or installation accuracy and the like.

Therefore, temperature monitoring has become more and more widely used in these fields. The quality of the most critical temperature monitoring equipment, namely the temperature sensor probe, is one of the important reasons for influencing the stability, accuracy and response time of temperature detection. The conventional temperature sensor probe has the following disadvantages in structural design:

1. bolt screw-in sensor probe: when the temperature sensor is installed on site, holes need to be drilled at the position of monitored equipment, the sensor probe is placed in the holes and then locked by bolts, the monitored equipment is easily damaged or even loses maintenance, the installation of site personnel is inconvenient, and more importantly, the sensor probe placed in the holes cannot be guaranteed to reliably contact with the hole wall, so that temperature data becomes unreliable;

2. pre-buried formula sensor probe: although the reliability of the pre-embedding mode is high, most manufacturers cannot cooperate with the pre-embedding mode, even if the pre-embedding mode is used, the pre-embedding mode can be pre-embedded, the pre-embedding mode cannot be maintained and replaced after being damaged, the tail end of an output connecting wire of a sensor probe is not processed and is easy to damage, wiring is needed when the pre-embedding mode is used on site, the construction difficulty is high, and the reliability is;

3. waterproof external sensor probe: at present, a plurality of waterproof sensor probes which are simply packaged exist in the market, but the sensor probes are very difficult to fix and install, the surfaces of the measured points and the sensor probes can be damaged by welding, the sensor probes can be contacted by being fixed with the sensor probes after the customized clamp is welded, and a series of problems such as falling and rust can be caused; if the adhesive tape is used, the adhesive tape is easy to fall off in a long-term severe environment, and the later maintenance workload is increased. And because of waterproof encapsulation, the encapsulation is very easy to be cracked with the data line junction, makes sensor probe damage.

4. The wiring of the data line and the acquisition equipment is usually completed in the junction box, the wiring is complex and is easy to generate errors, the field construction difficulty is high, and the internal wiring is easy to corrode or break by only depending on the protection of the junction box, so that the stability is influenced.

Therefore, the conventional temperature sensor probe has many disadvantages when applied to large-scale mechanical equipment in the industries of electric power, ports, wharfs, metallurgy, mines and the like.

The prior art has the following disadvantages:

1. the sensor probe is difficult to reliably contact with a measured point: the common sensor probe is difficult to be installed so that the temperature sensor probe is closely and reliably contacted with a measured point, the contact surface is too small or a gap exists, and great temperature deviation can be caused, even if temporary contact is ensured during installation, the displacement or falling off can be generated for a long time due to the limitation of the installation mode and precision.

2. The fixing method of the sensor probe and the measured point is complex: common sensor probe installation can't avoid welding and punching, has not only caused the installation and construction degree of difficulty to increase, can destroy equipment moreover and cause the damage even lose the warranty.

3. The sensor probe is easy to break off at the connection part with the data line: after the sensor probe is packaged, the material is hard, and the data line extending out of the package is contacted with the hard packaging material and is very easy to break in a long-term vibration environment.

4. The sensor probe is connected with the collector unreliably: the data line is connected with the collector data line in the junction box, when the number of the connecting wires is large, the conditions of virtual connection and short circuit occur, the workload is large, the error rate is high, meanwhile, a connector lug in the junction box is also easy to corrode and break under the severe environment, and the reliability is very poor.

5. The protection level needs to be further improved: the waterproof and corrosion-proof grades of the common sensor probe are not enough, even the common waterproof sensor probe on the market at present is only simply packaged, and for industrial sites with complex environment, the sensor probe is often finally damaged due to too little condensation or corrosion.
