[0043] The first embodiment of the rotating shaft oil leakage detection device 1 includes: an oil-absorbing swelling rubber 11 and an RFID strain sensing element 12. The oil-absorbing swelling rubber 11 is installed and closely attached to the rotating shaft oil seal 51 of the reducer 5, and there are a plurality of RFID strain sensing elements 12, which are attached to different positions on the surface of the oil-absorbing swelling rubber 11. When the rotating shaft of the reducer leaks oil, the oil-absorbing swelling rubber 11 expands and drives the RFID strain sensing element 12 to deform. The strain effect changes the port impedance of the RFID strain sensing element 12, thereby changing the tag information of the RFID strain sensing element 12. If the tag information of one RFID strain sensing element 12 changes, an oil leakage signal can be obtained.
[0044] like Figure 4As shown, the front end of the pressure and temperature detection device 2 (i.e., arranged on the side of the reducer inner wall 53) is a pressure and temperature sensing head 21; the middle part of the pressure and temperature detection device has a thread 22, which is used to be fastened and installed on the threaded reducer exhaust hole; the tail end of the pressure and temperature detection device is a hexagonal screw head 23, which is convenient for tightening the screw with a wrench; the tail end of the pressure and temperature detection device (i.e., on the side of the reducer outer wall 52) has a pressure and temperature detection processing and wireless power supply module 24, which supplies power to the pressure and temperature sensing head 21 and receives its sensing signal through a transmission line 25; an exhaust channel 26 is provided in the pressure and temperature detection device, and a spherical valve core 27 is provided in the exhaust channel, and a spring 28 is connected to one end of the spherical valve core, and the spring is fixed at one end of the exhaust channel.

The oil leakage alarm terminal 4 includes a data display interface, an oil leakage alarm module, and a pressure and temperature monitoring module. The data display interface is used to display the real-time pressure value and temperature value of the reducer; the pressure and temperature monitoring module compares the real-time pressure value and temperature value with the historical pressure value and temperature value. When the difference between the real-time value and the historical value is greater than 20%, the pressure and temperature abnormality signal is triggered, the abnormal data is recorded, and a report is generated; when the oil leakage alarm terminal receives the oil leakage signal, the oil leakage alarm module is triggered, and the oil leakage alarm module sends a text message to the maintenance personnel's mobile communication device to inform them of the oil leakage.
[0046] Optional, such as Figures 5 to 7As shown, the rotating shaft oil leakage detection device of the utility model is also provided with a second scheme: that is, an annular rotating shaft oil leakage detection device 13, the annular rotating shaft oil leakage detection device 13 includes a first half ring support block 13-1 and a second half ring support block 13-7, one end of the first half ring support block 13-1 and one end of the second half ring support block 13-7 are correspondingly provided with an arc-shaped telescopic connection component; the first half ring support block and the second half ring support block are pushed apart from each other by stretching the arc-shaped telescopic connection component, so as to expand the diameter of the combined block to realize the expansion and clamping and fixing to the inner wall 7 of the circular cylinder 6 on the outer periphery of the rotating shaft 8 of the reducer, as shown Figure 5 As shown, some of the reducers on the tobacco production equipment are provided with a circular cylinder 6 on the periphery of the rotating shaft, while some are not provided with the circular cylinder 6, the circular cylinder 6 can be directly welded to the periphery of the rotating shaft, so that if oil leakage occurs, the leaked oil will flow into the inner wall 7 of the circular cylinder 6. In this embodiment, the arc-shaped telescopic connection assembly includes an arc-shaped slot 13-9 arranged at one end of the first half-ring support block 13-1, an arc-shaped driving block 13-10 is arranged in the arc-shaped slot 13-9, and the inner side surface of the arc-shaped driving block 13-10 is provided with driving teeth for driving it to move; a driving screw 13-15 is rotatably arranged on the outside of the arc-shaped slot 13-9, and the driving screw 13-15 is fixed to the inner side surface of the first half-ring support block 13-1 through a fixing seat 13-14; a first driving tooth is arranged on the driving screw 13-15 corresponding to the driving tooth of the arc-shaped driving block 13-10, and the arc-shaped driving block 13-10 is moved along the arc-shaped slot by rotating the driving screw 13-15; the second half-ring support block 13 -7 is provided with an arc-shaped block 13-8 at one end corresponding to the arc-shaped slot; the arc-shaped block 13-8 can be inserted into the arc-shaped slot 13-9, and one end of the arc-shaped block 13-8 is squeezed by controlling the movement of the arc-shaped driving block 13-10. The arc-shaped block 13-8 is squeezed and squeezed out of the arc-shaped slot 13-9, and the other end of the first half ring support block and the other end of the second half ring support block are squeezed against each other. As the arc-shaped block 13-8 is continuously squeezed out of the arc-shaped slot 13-9, the diameter of the first half ring support block and the second half ring support block after combination is expanded, that is, the outer side walls of the first half ring support block and the second half ring support block squeeze the inner wall 7 of the circular cylinder 6, and at the same time, relying on the reaction force of the inner wall 7, it is fastened to the inner wall 7 of the circular cylinder 6. In some embodiments, in order to reduce the possibility of loosening due to the vibration of the equipment after installation on the production equipment, a telescopic spring 13-11 is also provided at the inner end of the arc-shaped slot 13-9 in this embodiment, and the telescopic spring 13-11 always squeezes the arc-shaped driving block 13-10 outward.
[0047] In the process of being fastened to the inner wall 7 of the circular cylinder 6, the body of the first half ring support block 13-1 and the body of the second half ring support block 13-7 will undergo certain deformation. In order to prevent the oil leakage monitoring from being disturbed or affected by the above deformation, the oil absorption sensing component of the utility model is combined with the following structure:

The advantage of such a setting is that even if some oil absorption occurs during the fixing operation of the first half ring support block and the second half ring support block, The oil absorption material 13-5 is deformed, and will not interfere with or affect the oil leakage detection; the upper part of the oil absorption groove 13-2 is also provided with a pressure-sensitive module 13-13; the oil absorption expansion of the oil absorption material is used to squeeze the pressure-sensitive module 13-13 to obtain the oil leakage signal. In some embodiments, the upper part of the oil absorption groove 13-2 is also provided with a spring groove 13-4, and a squeezing spring 13-12 is provided in the spring groove 13-4, and the squeezing spring 13-12 is provided between the oil absorption material 13-5 and the pressure-sensitive module 13-13; a flexible telescopic membrane 13-6 is also provided between the oil absorption material 13-5 and the squeezing spring 13-12.
