[0024] Embodiment

[0025] Please refer to Figures 1-4 As shown in the figure, the present utility model provides an electromagnetic flow sensor, which includes a stable frame 1, a detection electrode rod 2 and a lifting column leg 3. A detection electrode rod 2 penetrating from the top surface to the bottom surface is arranged on the top surface of the stable frame 1. The stable frame 1 is slidably connected with the detection electrode rod 2. The bottom of the detection electrode rod 2 is inserted into the measurement pipeline for detection. A connecting pile 6 is fixedly arranged on the top surface of the detection electrode rod 2. An analysis disk 8 is fixedly installed on the top of the connecting pile 6. Two mounting seats are installed in the middle of the analysis disk 8. The mounting seats are composed of two symmetrically arranged nuts. A detection disk 7 is fixedly installed on the side surface of the analysis disk 8. The detection disk 7 is composed of an electronic screen and an integrated device. The detection result can be viewed through the detection disk 7. A lifting column leg 3 is installed below the stable frame 1. The lifting column leg 3 is adjusted according to the moving distance of the detection electrode rod 2 to complete the positioning, which can increase the stability of the device.

[0026] As Figures 1-4As shown in the figure, a clamping assembly is arranged outside the detection electrode rod 2. The clamping assembly is composed of a first pressing plate 4, a first connecting rod 5, a second pressing plate 9, an anti-slip pad 10, a second connecting rod 11, a first clamping block 12, a second clamping block 13, a sliding groove 15 and a return spring 16. Symmetrical first pressing plate 4 and second pressing plate 9 are arranged outside the front and rear sides of the stable frame body 1. Symmetrical first connecting rod 5 and second connecting rod 11 are respectively fixedly arranged on the sides of the first pressing plate 4 and the second pressing plate 9 close to each other. Both the first connecting rod 5 and the second connecting rod 11 penetrate through the stable frame body 1 to the inside of the stable frame body 1 and are slidably connected with the stable frame body 1. The other end of the first connecting rod 5 is fixedly provided with a first clamping block 12. The second connecting rod 11 penetrates through the first clamping block 12 and is slidably connected with the first clamping block 12. The other end of the second connecting rod 11 is fixedly provided with a second clamping block 13. The first connecting rod 5 penetrates through the second clamping block 13 and is slidably connected with the second clamping block 13. A plurality of return springs 16 are fixedly arranged between the first clamping block 12 and the second clamping block 13. Anti-slip pads 10 are pasted on the outer sides of the first pressing plate 4 and the second pressing plate 9. The anti-slip pads 10 are made of rubber material. Symmetrical sliding grooves 15 are respectively arranged on the top surface and the bottom surface inside the stable frame body 1. Sliders adapted to the sliding grooves 15 are respectively fixedly arranged on the top surface and the bottom surface of the first clamping block 12 and the second clamping block 13. The sliders are slidably connected with the stable frame body 1 through the sliding grooves 15. During the detection, the staff does not need to maintain the position of the detection electrode rod 2 by hand, which is convenient for the staff to perform other operations, thereby improving the work efficiency of the staff.

[0027] Specifically, the staff simultaneously pinches the first pressing plate 4 and the second pressing plate 9 to make the first pressing plate 4 and the second pressing plate 9 approach each other. The movement of the first pressing plate 4 and the second pressing plate 9 respectively drives the first connecting rod 5 and the second connecting rod 11 to move towards the inside of the stable frame body 1. The movement of the first connecting rod 5 and the second connecting rod 11 drives the first clamping block 12 and the second clamping block 13 to move away from the detection electrode rod 2 at the same time, so as to release the limit on the detection electrode rod 2, and the return spring 16 is stretched. The distance of the up-and-down movement of the detection electrode rod 2 is adjusted according to the length of the detection pipeline, which is convenient for the detection electrode rod 2 to perform detection. After the detection electrode rod 2 moves up and down, the first pressing plate 4 and the second pressing plate 9 are released. The return spring 16 can pull the first clamping block 12 and the second clamping block 13 to drive the first clamping block 12 and the second clamping block 13 to approach each other until the first clamping block 12 and the second clamping block 13 are closely attached to the detection electrode rod 2, and the detection electrode rod 2 is clamped and limited again. Arc-shaped rubber pads 14 are respectively fixedly arranged on the sides of the first clamping block 12 and the second clamping block 13 close to each other. When the first clamping block 12 and the second clamping block 13 are closely attached to the detection electrode rod 2, the arc-shaped rubber pads 14 are arranged between the first clamping block 12 and the second clamping block 13 and the detection electrode rod 2. The arc-shaped rubber pads 14 can increase the friction force between the first clamping block 12 and the second clamping block 13 and the detection electrode rod 2, thereby improving the clamping effect of the clamping assembly on the detection electrode rod 2.

[0028] As Figures 1-4 shown, a positioning component is provided on the bottom surface of the stable frame 1. The positioning component is composed of a knob 17, a fixing block 18, a first bevel gear 19, a second bevel gear 20, a threaded rod 21 and a U-shaped guide plate 22. A knob 17 and a U-shaped guide plate 22 are provided at the bottom of the stable frame 1. A connecting block is fixedly provided between the stable frame 1 and the U-shaped guide plate 22. The inner side of the U-shaped guide plate 22 is slidably connected to the outer side of the lifting column leg 3. A rotating shaft is fixedly provided on the side surface of the knob 17. A fixing block 18 is fixedly provided on the bottom surface of the stable frame 1. The rotating shaft penetrates through the fixing block 18 and is rotatably connected to the inside of the fixing block 18. The bottom surface of the stable frame 1 is rotatably connected to the second bevel gear 20 through a bearing. A first bevel gear 19 is engaged below the second bevel gear 20. The side of the rotating shaft away from the knob 17 is fixedly connected to the first bevel gear 19. A threaded rod 21 is fixedly provided on the bottom surface of the second bevel gear 20. The inner side of the lifting column leg 3 is threadedly connected to the threaded rod 21. After the detection electrode rod 2 moves up and down, rotating the knob 17 can drive the lifting column leg 3 to move up and down.

[0029] Specifically, rotating the knob 17 drives the rotating shaft and the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate. The rotation of the second bevel gear 20 drives the threaded rod 21 to rotate. The U-shaped guide plate 22 can prevent the lifting column leg 3 from rotating when the threaded rod 21 rotates. The rotation of the threaded rod 21 drives the lifting column leg 3 to move up or down, so as to adjust the position of the lifting column leg 3.

[0030] Specific working principle:

[0031] When the device is in use, the staff simultaneously pinch the first pressing plate 4 and the second pressing plate 9 to make the first pressing plate 4 and the second pressing plate 9 approach each other. The movement of the first pressing plate 4 and the second pressing plate 9 drives the first connecting rod 5 and the second connecting rod 11 to move inwardly into the stable frame 1 respectively. The movement of the first connecting rod 5 and the second connecting rod 11 drives the first clamping block 12 and the second clamping block 13 to move away from the detection electrode rod 2 simultaneously, thus releasing the limit on the detection electrode rod 2. The return spring 16 is stretched. Adjust the distance of the up-and-down movement of the detection electrode rod 2 according to the length of the detection pipeline, which facilitates the detection of the detection electrode rod 2. After the detection electrode rod 2 moves up and down, release the first pressing plate 4 and the second pressing plate 9. The return spring 16 pulls the first clamping block 12 and the second clamping block 13, which can drive the first clamping block 12 and the second clamping block 13 to approach each other until the first clamping block 12 and the second clamping block 13 are in close contact with the detection electrode rod 2, and clamp and limit the detection electrode rod 2 again. When the first clamping block 12 and the second clamping block 13 are in close contact with the detection electrode rod 2, the arc-shaped rubber pad 14 is arranged between the first clamping block 12 and the second clamping block 13 and the detection electrode rod 2. The arc-shaped rubber pad 14 can increase the friction force between the first clamping block 12 and the second clamping block 13 and the detection electrode rod 2, thereby improving the clamping effect of the clamping assembly on the detection electrode rod 2. The staff does not need to maintain the position of the detection electrode rod 2 by hand during the detection, which facilitates the staff to perform other operations, thereby improving the work efficiency of the staff.

[0032] After the detection electrode rod 2 moves up and down, rotate the knob 17 to drive the rotating shaft and the first bevel gear 19 to rotate. The rotation of the first bevel gear 19 drives the second bevel gear 20 to rotate. The rotation of the second bevel gear 20 drives the threaded rod 21 to rotate. The U-shaped guide plate 22 can prevent the lifting column leg 3 from rotating when the threaded rod 21 rotates. The rotation of the threaded rod 21 drives the lifting column leg 3 to move up or down, thereby adjusting the position of the lifting column leg 3. Adjust the lifting column leg 3 to complete the positioning according to the moving distance of the detection electrode rod 2, which can increase the stability of the device. After the bottom of the detection electrode rod 2 is inserted into the measurement pipeline and moved to a suitable position, measurement is carried out, and the detection result is viewed by the detection disk 7.
