Description

Technical Field

[0001] This utility model relates to the field of liquid level gauge technology, and in particular to a magnetic telescopic liquid level gauge. Background Technology

[0002] A level gauge is an instrument used to measure the height (level) of a liquid medium in containers, tanks, pools, and other equipment. It plays a vital role in many fields, including industrial production, process control, environmental monitoring, and daily life, and is one of the key devices for achieving automated control, ensuring production safety, and optimizing resource management.

[0003] A float level gauge consists of a float, a rod, etc. It is installed on the top of the container via a connecting flange. The float floats on the liquid surface based on the principle that the volume of displaced liquid is equal. When the liquid level in the container changes, the float moves up and down. Due to magnetic attraction, the reed of the float level gauge is magnetically attracted, converting the change in liquid level into an electrical signal. The actual liquid level is then displayed digitally on a display instrument.

[0004] Existing upper and lower limit switches are typically rigidly fixed to a specific height of the container using threads. Adjustment requires manual physical operation: loosening the fixing device, manually moving the switch position up and down, recalibrating and aligning, and then tightening it again. This process is not only time-consuming and labor-intensive, but also inefficient. Therefore, to solve the above-mentioned technical problems, the inventors have proposed a magnetic telescopic level gauge. Utility Model Content

[0005] The purpose of this utility model is achieved through the following method: A magnetic telescopic level gauge includes a profile cylinder, a floating component, and an adjusting component. A mounting base is fixedly installed on the bottom surface of the profile cylinder. The adjusting component is located on one side of the profile cylinder. A first T-shaped groove and a second T-shaped groove are respectively opened on both sides of the outer wall of the profile cylinder. An upper limit magnetic switch is installed at the upper end of the first T-shaped groove, and a lower limit magnetic switch is installed at the lower end of the second T-shaped groove. A mounting groove is opened on one side of both the first and second T-shaped grooves. The adjusting component is located in the mounting groove. The adjusting component includes a mounting bracket, an adjusting bolt, and a linkage block. The mounting bracket is detachably installed in the mounting groove. The adjusting bolt is rotatably installed on the mounting bracket near the first and second T-shaped grooves. The linkage block is movably installed on the adjusting bolt and threadedly engaged with the adjusting bolt. The linkage block is fixedly connected to the upper limit magnetic switch and the lower limit magnetic switch.

[0006] In a further embodiment of the above description, the top and bottom of the mounting bracket are each provided with a bent extension at one end near the first T-slot and the second T-slot. The bent extension extends toward the first T-slot and the second T-slot. The top and bottom of the adjusting bolt are provided with positioning light rods near the bent extensions, and the middle of the bent extension is provided with a positioning light hole that matches the positioning light rod. When the operator controls the bolt to rotate by adjusting the nut, the cooperation between the positioning light rod and the positioning light hole ensures that the adjusting bolt will not disengage from the bent extension and the mounting bracket during rotation.

[0007] In a further embodiment of the above description, connecting screw holes are distributed along the edges of the top and bottom surfaces of the profile cylinder. A sealing cap is fitted over the top surface of the profile cylinder. The top surface of the sealing cap and the bottom surface of the mounting base are provided with connecting holes concentric with the connecting screw holes. The connecting holes and the connecting screw holes are fixedly connected by fixing bolts.

[0008] In a further embodiment of the above description, a floating groove is provided in the middle of the profile cylinder, extending through the top and bottom surfaces of the profile cylinder. A floating component is disposed within the floating groove. An observation port communicating with the floating groove is provided on the outer wall of the profile cylinder near the floating groove. Both ends of the observation port are provided with mounting slots, and a transparent scale plate is detachably installed in the mounting slots. Workers can directly observe the height position of the sensing magnet through the transparent scale plate, thereby directly determining the water level.

[0009] In a further embodiment of the above description, the floating assembly includes a float, a float rod, and an induction magnet. The float rod is movably mounted in the floating groove, with its bottom extending through the mounting base toward the bottom surface of the profile cylinder. The float is fixedly mounted on the bottom of the float rod, and the top of the float rod is provided with a displacement limiting platform that matches the floating groove. The induction magnet is fixedly mounted on the top surface of the displacement limiting platform. A limiting sleeve is detachably fitted at the lower end of the float rod near the float. The limiting sleeve is used to limit the movement of the float rod to prevent it from exceeding its travel range.

[0010] In a further embodiment of the above description, the mounting base has a cross-shaped distribution of fixing slots near the edge on its top surface, and two fixing brackets are fixedly installed on the side wall of the mounting base, with an included angle of 90° between the fixing brackets.

[0011] In a further embodiment of the above description, the fixed bracket is provided with a mounting slot at the end away from the mounting base, and a spirit level is detachably and fixedly installed in the mounting slot; the spirit level is fixed in the mounting slot to provide a horizontal installation effect when the mounting base is installed.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: Compared with the conventional use of threaded tightening for rigid fixation, this application adopts the setting of mounting bracket, adjusting bolt and linkage block. When it is necessary to adjust the height of the upper limit magnetic switch and the lower limit magnetic switch, it is only necessary to rotate the adjusting bolt. Through the threaded engagement relationship between the adjusting bolt and the linkage block, the upper limit magnetic switch and the lower limit magnetic switch form a guiding engagement with the T-slot, which only allows linear movement along the length of the slot. Therefore, when the adjusting bolt is rotated, it will drive the linkage block and the upper limit magnetic switch and the lower magnetic switch to move up and down along the T-slot and the adjusting bolt, so as to achieve the effect of quickly adjusting the position of the movable switch.

An observation port 18 communicating with the floating groove 17 is provided on the outer wall of the profile cylinder 1 near the floating groove 17. Both ends of the observation port 18 are provided with mounting slots 19, and a transparent scale plate 20 is detachably installed in the mounting slot 19.

[0019] The floating assembly includes a float 21, a float rod 22, and an induction magnet 23. The float rod 22 is movably mounted in the floating groove 17.
