DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The utility model provides Figure 1 and Figure 2 A dual-excitation dual-induction sensor for monitoring shown in the figure includes a detection pipeline 1, a detection mechanism 2 is sleeved on the outside of the detection pipeline 1, the detection mechanism 2 is composed of two groups of electromagnetic coils and two groups of induction units, a front connecting pipe sleeve 3 is arranged at the front end of the detection pipeline 1, a rear connecting pipe sleeve 4 is arranged on the rear side of the detection pipeline 1, two path partitions 5 are fixedly connected inside the detection pipeline 1, a path changing tube 6 is arranged between the detection pipeline 1 and the rear connecting pipe sleeve 4, two corresponding partitions 7 are fixedly connected inside the path changing tube 6, and an adjusting screw sleeve 8 is sleeved on the outside of the path changing tube 6. The sensor can be connected to the pipeline of the gear box through the front connecting pipe sleeve 3 and the rear connecting pipe sleeve 4 arranged at the front and rear ends, and the gear oil flowing in the pipeline enters the detection pipeline 1 through the path changing pipe sleeve 6 for detection, and then is discharged through the front connecting pipe sleeve 3. Since the shape of the fluid flowing through the sensor is related to the detection sensitivity of the sensor, the detection sensitivity can be controlled by controlling the shape of the gear oil flowing through the detection pipeline 1.

[0029] Preferably, two path partitions 5 divide the interior of the detection pipe 1 into three channels, namely, upper, middle and lower channels, and two corresponding partitions 7 divide the interior of the path change tube 6 into three channels, namely, upper, middle and lower channels. Therefore, the flow shape of the gear oil can be controlled by controlling the connection and blockage between the upper, middle and lower channels corresponding to the detection pipe 1 and the path change tube 6. Moreover, since the path change tube 6 is slidably connected to the interior of the rear end of the detection pipe 1, and the adjusting screw sleeve 8 sleeved on the outside of the path change tube 6 is threadedly connected to the outside of the rear end of the detection pipe 1, the position between the three channels inside the detection pipe 1 and the three channels inside the path change tube 6 can be controlled by rotating the adjusting screw sleeve 8, thereby controlling the connection and blockage between the three channels inside the detection pipe 1 and the three channels inside the path change tube 6.

[0030] like Figure 3-Figure 5 As shown, the inner rear sides of the left and right ends of the detection pipe 1 are fixedly connected with limiting slide bars 9, the front sides of the left and right ends of the path change tube 6 are provided with limiting slide grooves 10, and the limiting slide bars 9 are clamped in the limiting slide grooves 10 and can slide in the limiting slide grooves 10. When adjusting the positions of the three channels inside the detection pipe 1 and the three channels inside the path change tube 6, the corresponding relationship between the channels can be limited by the limiting slide bars 9 and the limiting slide grooves 10, so that the three channels inside the detection pipe 1 and the three channels inside the path change tube 6 can be accurately connected.

[0031] Preferably, sealing ports 11 are provided inside the upper and lower sides of the intersection of the rear ends of the two path partitions 5 and the detection pipe 1, and the two sealing ports 11 are rotatably connected with sealing rotary plates 12, and the rotation position is located inside the sealing ports 11 on the side close to the central axis of the detection pipe 1. When the sealing rotary plate 12 is rotated to the sealing port 11, the upper and lower channels of the detection pipe 1 and the path change tube 6 are blocked, so that the gear oil inside the path change tube 6 can only pass through the middle channel inside the detection pipe 1, and the flow shape of the gear is flat when flowing through the detection mechanism 2, thereby improving the detection sensitivity of the sensor. When the sealing rotary plate 12 is rotated out of the sealing port 11, the upper, middle and lower channels of the detection pipe 1 and the path change tube 6 are all connected, so that the gear oil inside the path change tube 6 flows through the detection mechanism 2 in a cylindrical shape, thereby reducing the sensitivity of the sensor.

[0032] like Figure 3-Figure 6As shown, a receiving groove 13 perpendicular to the inner wall of the detection pipe 1 is opened inside the rear end of the sealing rotary plate 12, and a linkage rod 14 is rotatably connected to the side of the storage groove 13 away from the central axis of the detection pipe 1, and a sealing ring 15 is fixedly connected to the outer side of the front end of the path change pipe 6. A rotating groove 16 perpendicular to the inner wall of the path change pipe 6 is opened at the center of the front ends of the two corresponding partitions 7. One end of the linkage rod 14 is rotatably connected to the side of the storage groove 13 away from the central axis of the detection pipe 1, and the other end of the linkage rod 14 is rotatably connected to the inside of the rotating groove 16. When the adjusting screw sleeve 8 is screwed backward, the path change pipe 6 slides backward inside the rear end of the detection pipe 1, and the corresponding partition 7 inside the path change pipe 6 pulls the linkage rod 14 backward through the rotating groove 16, and the linkage The rod 14 then pulls the sealing rotary plate 12 backward through the receiving groove 13, allowing the sealing rotary plate 12 to rotate out from the inside of the sealing port 11, thereby connecting the three channels between the detection pipeline 1 and the path change tube 6. When the adjusting screw sleeve 8 is screwed forward, the path change tube 6 slides forward together with the corresponding partition plate 7, and the corresponding partition plate 7 pushes the sealing rotary plate 12 to rotate into the inside of the sealing port 11 through the linkage rod 14, thereby blocking the rear ends of the upper and lower channels of the detection pipeline 1, so that the gear oil inside the path change tube 6 can only flow through the middle channel of the detection pipeline 1, thereby changing the shape of the gear oil flowing through the detection mechanism 2, improving the sensitivity of the sensor, and the sealing ring 15 can be used to seal the inner walls of the detection pipeline 1 during the sliding process.

[0033] Preferably, sealing rings are provided inside the inner wall of the front end of the sealing port 11 and the inner wall of the rear end of the detection pipe 1. When the path changing tube 6 slides to the frontmost side, the sealing ring inside the inner wall of the front end of the sealing port 11 can seal the upper and lower side channels of the detection pipe 1 and the sealing rotary plate 12. When the path changing tube 6 slides to the rearmost side, the sealing ring inside the inner wall of the rear end of the detection pipe 1 can seal the retaining ring and the sealing ring 15 at the rear end opening of the detection pipe 1.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
