DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The following is a further description of the present utility model in conjunction with the accompanying drawings and specific embodiments, so as to more clearly understand the technical idea required to be protected by the present utility model.

[0016] As Figures 1 to 3 shown, an integrated dual-channel redundant liquid level gauge includes a liquid inlet pipe 1, a shunt pipe 2, a driving motor 3 and two detection tubes 4. The liquid inlet pipe 1 is communicated with the middle of the shunt pipe 2. The driving motor 3 is arranged outside the shunt pipe 2. The output end of the driving motor 3 extends into the liquid inlet pipe 1 from the shunt pipe 2, and a cleaning head is arranged at the output end of the driving motor 3. The two ends of the shunt pipe 2 are correspondingly communicated with the two detection tubes 4, and two control switches 5 are correspondingly arranged at the connection positions of the shunt pipe 2 and the two detection tubes 4. A mounting seat is arranged at the top of the detection tube 4. A magnetic guide rail 6 is arranged at the bottom surface of the mounting seat. A floating ball 7 is slidably connected to the magnetic guide rail 6, and a permanent magnet steel is arranged inside the floating ball 7.

[0017] The working principle of the integrated dual-channel redundant liquid level gauge described in the utility model is realized through the mutual cooperation of the liquid inlet pipe 1, the shunt pipe 2, the drive motor 3 and the detection pipe 4. As Figures 1 to 3 shown, the staff can open one control switch 5 and close the other control switch 5. In this way, the liquid inlet pipe 1 is first connected to a detection pipe 4, and the floating ball 7 of the detection pipe 4 connected to the liquid inlet pipe 1 cooperates with the magnetic guide rail 6 to detect the liquid level height parameter. The control switch 5 adopts a conventional valve switch for controlling the opening and closing of the pipeline, which will not be described in detail. Subsequently, the staff can open the other control switch 5, and the other detection pipe 4 is connected to the liquid inlet pipe 1, and the other detection pipe 4 also detects the liquid level height parameter through the floating ball 7 and the magnetic guide rail 6. If the liquid level height parameters detected by the two detection pipes 4 are the same, the two detection pipes 4 are working properly. If the liquid level height parameters detected by the two detection pipes 4 are different, one of the detection pipes 4 fails, and the staff needs to deal with it in time. In addition, the drive motor 3 can drive the cleaning head to rotate, so that the cleaning head can clean the liquid inlet pipe 1. Compared with the traditional liquid level gauge, the integrated dual-channel redundant liquid level gauge can reduce the possibility of blockage of the liquid inlet pipe 1, and the two detection pipes 4 respectively detect the liquid level and can be compared, which can improve the accuracy of detection, and enable the staff to timely discover the failure of the detection pipe 4 and deal with and correct it.

[0018] Specifically, the cleaning head is located between the two control switches 5. The cleaning head includes a connecting cylinder 8 and cleaning blades 9. The connecting cylinder 8 is connected to the output end of the drive motor 3, and a plurality of the cleaning blades 9 are evenly arranged in a circle on the connecting cylinder 8. Among them, an arc-shaped scraping plate 10 is arranged on the side of the cleaning blade 9 away from the connecting cylinder 8, and the arc-shaped scraping plates 10 of the plurality of cleaning blades 9 extend in the counterclockwise direction. As Figures 1 to 3 shown, the arc-shaped scraping plate 10 corresponds to the structure of the liquid inlet pipe 1 and can contact the pipe wall of the liquid inlet pipe 1. The output end of the drive motor 3 drives a plurality of cleaning blades 9 to rotate through the connecting cylinder 8. The cleaning blades 9 stir the liquid and the arc-shaped scraping plate 10 cleans the pipe wall of the liquid inlet pipe 1, which can reduce the possibility of blockage of the liquid inlet pipe 1 so as not to affect the accuracy of detection by the detection pipe 4.

[0019] Further, an overflow pipe 11 is arranged at the top of the detection pipe 4, and a drain valve 12 is arranged at the connection between the detection pipe 4 and the overflow pipe 11. Among them, the mounting seat includes a hollow seat body 13 and a plurality of through rods 14. The hollow seat body 13 is respectively communicated with the magnetic guide rail 6 and the plurality of through rods 14, and the plurality of through rods 14 are connected to the detection pipe 4 and communicated with the outside. Furthermore, a limiting plate 15 is arranged at the bottom end of the magnetic guide rail 6, a through groove is arranged on the floating ball 7, and the floating ball 7 is slidably connected to the magnetic guide rail 6 through the chute. As Figures 1 to 3As shown, the overflow pipe 11 at the top of the detection tube 4 can be controlled to open and close through the drain valve 12. When the drain valve 12 is opened, the detection tube 4 is connected to the overflow pipe 11, so that excessive liquid in the detection tube 4 can be discharged from the overflow pipe 11. The limiting plate 15 can prevent the floating ball 7 from falling off the magnetic guide rail 6. A plurality of magnetic switches (not shown in the figure) can be arranged on the magnetic guide rail 6, and the magnetic guide rail 6 can lead wires through the hollow seat body 13 and the through rod 14 and be connected to an external control processor (not shown in the figure). When the floating ball 7 moves along the magnetic guide rail 6, the magnetic guide rail 6 senses the permanent magnet (not shown in the figure) on the floating ball 7, and the induction signal generated by the magnetic guide rail 6 is transmitted to the control processor to measure the liquid level height result. The staff compares and confirms according to the detection results of the two detection tubes 4 obtained, so as to improve the detection accuracy.
