[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] This utility model provides an online monitoring sensor for the iron content of oil in mechanical equipment, such as... Figures 1 to 6 As shown.

[0032] Example 1:

[0033] A sensor for online monitoring of iron content in mechanical equipment oil includes a base tube 1, which is installed on an oil delivery pipeline and connected to the oil delivery pipeline. A sampling part 2 is provided inside the base tube 1. The sampling part 2 slides inside the base tube 1 along the axis of the base tube 1. The sampling part 2 is cylindrical with an open top. A cavity 3 is provided in the lower side wall of the sampling part 2. A weighing sensor is installed inside the cavity 3.

[0034] The sampling unit 2 is driven by the lifting push rod 5 installed on the base pipe 1. When sampling, the lifting push rod 5 is activated, and the piston rod of the lifting push rod 5 completes one retraction-extension cycle, which can drive the sampling unit 2 down into the oil delivery pipeline and then return to the base pipe 1, so that the sampling unit 2 completes one sampling operation. At this time, the weighing sensor can obtain the weight of the oil sample inside the sampling unit 2.

[0035] An adsorption component is installed inside the base tube 1, which can adsorb iron particles contained in the sample inside the sampling section 2. At this time, the data obtained by the weighing sensor will change accordingly. By comparing the data of the weighing sensor before and after the adsorption component adsorbs iron particles, the iron content in the oil can be determined.

[0036] The outer diameter of the sampling section 2 is matched with the inner diameter of the base pipe 1. When the sampling section 2 is inside the base pipe 1, it can block the lower end of the base pipe 1, thereby sealing the oil delivery pipeline and not affecting the delivery of oil. The outer ring surface at the upper end of the sampling section 2 is a cone shape that is thinner at the top and thicker at the bottom, which can better return to the inside of the base pipe 1 during the upward process of the sampling section 2.

[0037] Example 2:

[0038] The sampling unit 2 is fixedly connected to the lifting rod 4 which is slidably installed inside the base tube 1. The upper end of the lifting rod 4 passes through the base tube 1 and is fixedly connected to multiple fixing plates 6. A lifting push rod 5 is provided below the fixing plate 6. The outer shell of the lifting push rod 5 is installed on the base tube 1. The piston rod of the lifting push rod 5 is fixedly connected to the fixing plate 6. Multiple lifting push rods 5 are distributed around the lifting rod 4, which can stably control the lifting of the sampling unit 2.

[0039] Multiple mounting rods 7 are fixedly connected to the opening of the sampling section 2. The multiple mounting rods 7 are distributed around the circumference of the sampling section 2. Fixed rings 8 are fixedly connected between the multiple mounting rods 7. The fixed rings 8 are fixedly connected to the lifting rod 4. The lower end of the lifting rod 4 extends into the interior of the sampling section 2 and is suspended inside the sampling section 2, so as not to affect the weighing sensor inside the lower side wall of the sampling section 2.

[0040] The adsorption component uses an electromagnet 9, which is installed inside the lower end of the lifting rod 4. When the electromagnet 9 is energized, it generates magnetic force to adsorb iron particles in the oil sample in the sampling section 2. Since the electromagnet 9 and the lifting rod 4 are supported by the mounting rod 7 and the fixing ring 8, the iron particles are supported by the lifting rod 4 when adsorbing them. At this time, the data measured by the weighing sensor does not include the weight of the iron particles. When the electromagnet 9 is de-energized, the iron particles are suspended in the oil or deposited on the inner wall of the lower end of the sampling section 2. Therefore, the data measured by the weighing sensor at this time includes the weight of the iron particles. By calculating the difference between the data measured by the weighing sensor before and after the electromagnet 9 is energized and de-energized, the iron content in the oil can be determined.

[0041] Example 3:

[0042] Based on Embodiment 2, in order to avoid the sample remaining inside the sampling section 2 from interfering with subsequent detection, a cleaning component is provided. The cleaning component includes a suction tube 10, which is fixedly connected to the base tube 1. One end of the suction tube 10 is connected to an external suction device, and the other end extends into the interior of the base tube 1. When the sampling section 2 is located inside the base tube 1, the end of the suction tube 10 located inside the base tube 1 will be inserted into the interior of the sampling section 2.

[0043] In order to enable the suction tube 10 to better extract the oil sample inside the sampling section 2, the lower side wall of the sampling section 2 is made into an inclined surface, and the lowest point of the lower side wall of the sampling section 2 is located below the suction tube 10, so that the suction tube 10 can extract the oil inside the sampling section 2 completely.

[0044] To prevent iron particles from remaining on the surface of the lifting rod 4 after the electromagnet 9 is de-energized, thus interfering with the detection work on the lower side, both the fixing ring 8 and the lifting rod 4 are designed as hollow structures. The fixing ring 8 has a flushing port on its lower side that is inclined towards the axis of the lifting rod 4. The lifting rod 4 is connected to an external water pump. When the suction pipe 10 extracts the oil sample from the sampling section 2, the external water pump is activated. The water pump will pump the external cleaning fluid into the interior of the lifting rod 4 and then discharge it through the flushing port on the lower side of the fixing ring 8 to flush the outer wall of the end of the lifting rod 4 located inside the sampling section 2. The residual flushing fluid will also be extracted by the suction pipe 10.

[0045] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
