[0002] In the production process of polysilicon, a water cooling tower is required to cool the circulating cooling water. During the operation of the fan (for cooling), a three-in-one probe is required to measure the vibration, oil temperature and oil level of its motor in real time, so as to interlock and shut down the fan in time when the fan is operating abnormally, thereby avoiding economic losses and personal injuries due to equipment damage.
[0003] At present, the oil level measurement principle of common three-in-one probes is mostly capacitive, such as Figure 1 As shown, a hole is opened on the side of the probe rod to let oil in (the capacitance measuring element is located in the probe rod and near the hole), and the actual oil level is measured by combining the capacitance value and the changing trend of the oil level through the communicating vessel principle. However, the probe rod and the measuring method are seriously affected by the operation of the motor, especially during the start and stop of the fan, the oil level fluctuates frequently, the lubricating oil rotates, and the lubricating oil is continuously pressed into the inside of the probe rod from the side, which causes the fluctuation and distortion of the measured value, and easily triggers the shutdown interlock to affect the normal production operation; in addition, when the oil level fluctuates frequently, the capacitance measuring element located in the probe rod is easily affected by the impact of the lubricating oil, thereby shortening the working life and having a very high damage rate.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
[0034] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0035] Example
[0036] See also Figure 1 to Figure 3 This embodiment provides a novel three-in-one probe 1, including a probe body 12, a capacitance measuring element (not shown in the figure), a probe rod 13, an oil inlet hole 131 and a breathing hole 132.
[0037] The capacitance measuring element and the probe rod 13 are both connected to the probe body 12 , and the capacitance measuring element is located inside the probe rod 13 .
[0038] In a specific implementation scenario, the probe rod 13 and the probe body 12 are detachably connected by threaded connection, so as to facilitate the disassembly and assembly between the probe rod 13 and the probe body 12. Specifically, the bottom of the probe body 12 has a fixing nut 121, and the upper end of the probe rod 13 has an external thread used in conjunction with the fixing nut 121.
[0039] The oil inlet hole 131 is formed at the bottom of the probe rod 13 .
[0040] In a specific implementation scenario, a plurality of oil inlet holes 131 are distributed at the bottom of the probe rod 13. The reason for such a setting is that after the lubricating oil has been running for a long time, some impurities will be present. By ensuring smooth oil inlet while reducing the aperture as much as possible (that is, the number of oil inlet holes 131 is greater than 1), most of the impurities can be isolated from entering the interior of the probe rod 13, thereby ensuring the normal operation of the new three-in-one probe 1.
[0041] The breathing hole 132 is provided on the upper side of the probe rod 13, and is arranged close to the probe body 12 to ensure that the breathing hole 132 is always located above the lubricating oil level. The function of the breathing hole 132 is to facilitate the lubricating oil to enter the probe rod 13 from the oil inlet hole 131, and at the same time, to prevent the lubricating oil from directly entering the probe rod 13 from the breathing hole 132.
[0042] In other embodiments, the breathing hole 132 is opened on the middle side or lower side of the probe rod 13. This needs to be considered in combination with the length and installation position of the probe rod 13, as long as it can be ensured that the breathing hole 132 is always located above the lubricating oil level.
[0043] In combination with the above content, the working principle and beneficial effects of this embodiment are:
[0044] In the prior art, when the hole is opened on the side of the probe rod 13, because the internal lubricating oil is constantly rotating, when the lubricating oil impacts the outer wall of the probe rod 13 from the side, there is a continuous pressure to press the lubricating oil from the side opening to the inside of the probe rod 13, which will cause the measured value of the capacitance measuring element to fluctuate and be distorted. However, in this embodiment, the oil inlet hole 131 is opened at the bottom of the probe rod 13, which is not affected by the rotating impact of the lubricating oil, but only by the static pressure, so the measured value of the capacitance measuring element will not fluctuate and be distorted, thereby improving the measurement stability and measurement accuracy.
[0045] In addition, the oil inlet hole 131 is opened at the bottom of the probe rod 13. When the rotating lubricating oil impacts the outer wall of the probe rod 13, there is no problem of the lubricating oil being pressed into the inside of the probe rod 13 from the side and directly impacting the capacitance measuring element. In this way, the influence of the lubricating oil fluctuation on the service life of the capacitance measuring element can be weakened, and the damage rate of the capacitance measuring element can be reduced.
[0046] From the above content, it can be seen that this embodiment can achieve many beneficial effects through simple improvements, which is in line with the concept of reducing costs and increasing efficiency.
[0047] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. In the absence of conflicts, the embodiments of the present application and the features in the embodiments may be combined with each other at will. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
