[0037] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] An oil product monitoring device is a device that samples, detects, and analyzes oil products (such as "lubricating oil") in a closed oil tank of industrial equipment, and finally drives the oil products back into the oil tank. The oil product monitoring device usually includes an oil pipe, a sampling component, a detection component, and an oil return component. Among them, in order not to destroy the original structure of the oil tank, the sampling component is usually transferred to the drain port at the bottom of the oil tank to realize the shared drain port at the bottom of the oil tank and sample the oil products inside the oil tank. However, the sampling tube in the current sampling assembly is usually a straight tube. When the sampling tube goes deep into the oil tank from the drain port to sample, the oil extracted by the sampling tube is prone to contain precipitated impurities or precipitated condensed water, resulting in poor purity of the oil sampled by the sampling tube, which is easy to cause a decrease in the accuracy of oil product detection.

[0039] In view of this, an embodiment of the present invention provides a sampling assembly 200, including a sampling tube 2. When the sampling tube 2 penetrates into the oil tank to extract oil, the probability of precipitated impurities or precipitated condensed water entering the sampling tube 2 can be reduced, thereby improving the purity of the oil sampling and improving the accuracy of oil detection.

[0040] For the sampling assembly 200 described above, see Figures 1 to 3The sampling assembly 200 includes a first adapter 1 and a sampling tube 2; the first adapter 1 is provided with a first connection portion 11 and a second connection portion 12, the first connection portion 11 and the second connection are arranged at a preset angle, the first connection portion 11 is used to connect to the drain outlet of the oil tank, and the second connection portion 12 is used to connect to the oil product monitoring device, the first adapter 1 is provided with a first channel 13 extending from the first connection portion 11 to the second connection portion 12, one end of the first channel 13 passes through the first connection portion 11, and the other end of the first channel 13 passes through the second connection portion 12; the sampling tube 2 includes a first tube body 21 and a second tube The first tube body 22 is a tube body 21, one end of which is plugged into the first channel 13, the first tube body 21 is communicated with the first channel 13, the other end of the first tube body 21 extends out of the first channel 13 and is connected with the second tube body 22, the second tube body 22 and the first tube body 21 are arranged at a preset angle, the second tube body 22 is communicated with the first tube body 21, and the second tube body 22 and the first tube body 21 are used to at least partially penetrate the sewage outlet of the oil tank and penetrate into the oil tank; wherein, when the first connecting portion 11 is connected to the sewage outlet of the oil tank and the second connecting portion 12 is connected to the oil product monitoring device, the first channel 13 is used for supplying oil flow sampling of the oil tank.

[0041] Through the above method, when the first connecting part 11 is connected to the drain outlet of the oil tank, the second tube body 22 and the first tube body 21 at least partially penetrate the drain outlet of the oil tank and penetrate into the interior of the oil tank. The second tube body 22 is bent or tilted and located above the first tube body 21, which can reduce the probability of precipitated impurities or precipitated condensed water entering the sampling tube 2, improve the purity of the oil sampling, and improve the accuracy of oil detection.
