Problems solved by technology

[0003] However, the existing detection method of axle temperature and rail smoothness is to use infrared spot thermometer to carry out manual detection. This monitoring method not only has a huge workload and is very inconvenient, but also is prone to missed detection, which cannot realize real-time detection, and is also harmful to workers. hidden dangers to work safety

Embodiment

[0050] Such as figure 1 As shown, the present invention provides a zero-carbon sensing device for rail train axle temperature, which is used to monitor and warn the train axle temperature to ensure the safety of train operation. The device includes:

[0051] Top cover 1, such as image 3 As shown, it is a circular structure, and the four countersunk through holes 1-1 provided on the surrounding edges are fixedly connected with the upper wall shell 5 through bolts; the structure of the countersunk through holes 1-1 makes the upper end surface of the bolt and the top cover 1 The upper surface is flat and has a good anti-seismic effect, which can prevent the bolts from loosening; a circular groove 1-2 is dug in the middle of the bottom surface, which is used to provide space for the induction coil A2 to vibrate up and down; the bottom is surrounded by a telescopic rod 1 -3 threaded holes.

[0052] Arc bracket 19, such as Figure 4 As shown, its cross-section is a crescent-shap...

Abstract

The invention relates to a rail train axle temperature zero-carbon sensing device which is fixed to the axle end of a train in a suspended mode through a mounting support. The device comprises a temperature acquisition and sending module, and a first-layer power generation structure, a second-layer power generation structure and a third-layer power generation structure which are arranged in order from top to bottom, the first-layer power generation structure is used for generating electric energy by cutting magnetic induction lines through an induction coil and generating electric energy according to the piezoelectric effect of piezoelectric ceramics to supply power to the device, the second-layer power generation structure is fixedly connected with the first-layer power generation structure through a buckle and used for generating electric energy by cutting magnetic induction lines through the induction coil and generating electric energy according to the piezoelectric effect of piezoelectric ceramics to supply power to the device, the third-layer power generation structure is fixedly connected to the second-layer power generation structure by bolts, and generates electric energy through the piezoelectric effect of a piezoelectric ceramic film installed on an installation support. Compared with the prior art, the sensing device has the advantages of no need of external power supply, convenient disassembly and assembly, compact structure, convenient test and the like.

Description

technical field [0001] The invention relates to the field of rail train safety operation detection, in particular to a rail train axle temperature zero-carbon sensing device. Background technique [0002] Safety issues during train operation and my country's "carbon neutral" and "carbon peak" requirements have always been the focus of attention. In order to speed up the research on key technologies of carbon zero emission, in recent years, with the vigorous development of my country's rail transit industry, "China's train speed" has become a new business card that amazes the world. However, when the train is running at high speed, it will inevitably cause frequent impacts between the locomotive and the rail, and it is often accompanied by the overheating of the axle temperature. If it continues to run, it will cause the axle to wear and become thinner in severe cases, and the axle temperature will be too high to cause the axle to break or melt down, which will have very ser...
