Description

Technical Field

[0001] The utility model relates to the technical field of liquid level gauges, and particularly relates to a top-mounted magnetic flap liquid level gauge. Background Art

[0002] A liquid level gauge is a liquid level measuring device used to measure liquid media in containers, tanks, etc. It can detect the position of the liquid in the tank and is widely used in industries such as electric power, petroleum, chemical industry, metallurgy, environmental protection, ships, construction, food, etc. The magnetic flap liquid level gauge is detected based on the principles of buoyancy and magnetic coupling. The magnetic flap liquid level gauge is further divided into a top-mounted magnetic flap liquid level gauge and a side-mounted magnetic flap liquid level gauge according to actual needs. The top-mounted magnetic flap liquid level gauge is generally installed on the top of the container and is particularly suitable for underground storage tanks or other situations where the surrounding space is limited, and is currently widely used.

[0003] The existing top-mounted magnetic flap liquid level gauge generally consists of upper and lower conduits, etc. The floating ball in the lower conduit drives the magnetic connecting rod in the upper conduit to move up and down as the liquid level moves up and down. The magnetic steel in the magnetic connecting rod drives the magnetic flap indicator through the principle of magnetic coupling, so as to display the liquid level or interface level in the container in red and white. When installing this magnetic flap oil level gauge, it generally inserts the lower conduit into the tank first and fixes the liquid level gauge to the upper surface of the tank body through bolts.

[0004] After the existing liquid level gauge is fixed to the tank body, it cannot move. If you want to change the position of the liquid level gauge inside the tank body, you need to remove and reinstall the liquid level gauge, which is more cumbersome to operate. To solve this technical problem, the utility model proposes a top-mounted magnetic flap liquid level gauge. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a top-mounted magnetic flap liquid level gauge, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A top-mounted magnetic flap liquid level gauge, comprising a fixing plate, an upper conduit and a lower conduit. A sliding plate is slidably connected to the inner wall of the fixing plate. The upper surface and the lower surface of the sliding plate are respectively fixed to the upper conduit and the lower conduit. A rotating ring is rotatably connected to the outer surface of the upper conduit. A connecting plate is fixedly connected to the outer surface of the rotating ring. One side of the connecting plate away from the rotating ring is detachably connected to a fixing arm. A sliding arm is slidably connected to the inner wall of the fixing arm. A sliding mechanism is arranged inside the fixing arm and the sliding arm. One end of the sliding arm is fixedly connected to a telescopic rod. A rolling mechanism is arranged at the bottom of the telescopic rod. Scale lines are arranged on the upper surface of the sliding arm.

[0008] Preferably, a measuring assembly is arranged inside the lower conduit, an extrusion rod is threadedly connected to the inner wall of the fixed plate, and the lower surface of the extrusion rod is in contact with the sliding plate.

[0009] Preferably, a limiting ring is fixedly connected to the outer surface of the upper conduit, and the number of the limiting rings is two. The two limiting rings are respectively located on the upper surface and the lower surface of the rotating ring.

[0010] Preferably, the sliding mechanism includes a tension spring. One end of the tension spring is fixedly connected to the fixed arm, and the other end of the tension spring is fixedly connected to the sliding arm.

[0011] Preferably, a sliding groove is formed inside the fixed arm, a slider is slidably connected to the inner wall of the sliding groove, and the outer surface of the slider is fixedly connected to the sliding arm.

[0012] Preferably, the rolling mechanism includes a fixed block. The upper surface of the fixed block is fixedly connected to the telescopic rod, and a rotating wheel is rotatably connected to the inner wall of the fixed block.

[0013] Preferably, a threaded rod is threadedly connected to the inner wall of the telescopic rod, and a rubber plate is fixedly connected to the end of the threaded rod.

[0014] Compared with the prior art, the present utility model has the following beneficial effects:

[0015] In the present utility model, by providing components such as a fixed plate and a sliding plate, when it is necessary to adjust the positions of the lower conduit and the upper conduit, the telescopic rod is used to squeeze the side of the tank body, and the position of the end of the fixed arm on the scale line of the sliding arm is observed to obtain the total length of the fixed arm and the sliding arm added together. The sliding plate is slid according to the scale size to make the sliding plate slide to a suitable position without removing the upper conduit, etc., achieving the effect of facilitating the adjustment of the positions of the upper conduit and the lower conduit, thereby solving the problem that the existing liquid level gauge cannot move after being fixed to the tank body. If you want to change the position of the liquid level gauge inside the tank body, you need to remove the liquid level gauge and reinstall it, which is rather cumbersome to operate.

[0016] In the present utility model, by providing components such as a connecting plate and a rolling mechanism, the threaded rod can be screwed to drive the rubber plate to move closer to the tank body, so that the rubber plate squeezes the tank body, thereby fixing the lower end of the telescopic rod to the tank body to prevent the telescopic rod from rotating around the tank body, achieving the effect of preventing the telescopic rod from rotating. According to actual needs, the fixed arm can also be directly removed from the connecting plate to reduce the occupied space and increase the practicality. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0023] To make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] As Figures 1-5 shown, a top-mounted magnetic flap level gauge includes a fixed plate 1, an upper conduit 12 and a lower conduit 11. The inner wall of the fixed plate 1 is slidably connected with a sliding plate 2. The fixed plate 1 is circular in shape, and the sliding plate 2 is annular in shape. A cavity with a volume larger than that of the sliding plate 2 is provided inside the fixed plate 1 to facilitate the sliding of the sliding plate 2 therein.

[0025] The upper surface and the lower surface of the sliding plate 2 are respectively fixedly connected with the upper conduit 12 and the lower conduit 11. A measuring component 13 is arranged inside the lower conduit 11, and the measuring component 13 is also arranged inside the upper conduit 12. The measuring component 13 is composed of a floating ball and a magnetic connecting rod, etc., and can measure and detect the position of the liquid in the tank.

[0026] The outer surface of the upper conduit 12 is rotatably connected with a rotating ring 3. The outer surface of the rotating ring 3 is fixedly connected with a connecting plate 4. The side of the connecting plate 4 away from the rotating ring 3 is detachably connected with a fixed arm 5. The connecting plate 4 and the fixed arm 5 are fixedly connected by bolts and can be disassembled when needed. The inner wall of the fixed arm 5 is slidably connected with a sliding arm 6.

[0027] The inside of the fixed arm 5 and the sliding arm 6 is provided with a sliding mechanism 7. The sliding mechanism 7 includes a tension spring 701. One end of the tension spring 701 is fixedly connected to the fixed arm 5, and the other end of the tension spring 701 is fixedly connected to the sliding arm 6. The tension spring 701 can drive the sliding arm 6 to move closer to the inside of the fixed arm 5, so that the sliding arm 6 always has an elastic force towards the sliding arm 6. A chute 702 is opened inside the fixed arm 5. The inner wall of the chute 702 is slidably connected with a slider 703. The outer surface of the slider 703 is fixedly connected to the sliding arm 6. The end of the chute 702 does not exceed the end of the fixed arm 5. When the slider 703 moves to the end of the fixed arm 5, it is blocked by the fixed arm 5 and cannot slide out, so that the sliding arm 6 cannot slide out of the inside of the fixed arm 5.

[0028] One end of the sliding arm 6 is fixedly connected to a telescopic rod 8. A rolling mechanism 9 is arranged at the bottom of the telescopic rod 8. The telescopic rod 8 is composed of two rods combined together, similar to the sliding arm 6 and the fixed arm 5, but there is no tension spring 701 inside, and it can be manually lengthened and shortened to facilitate the movement of the rolling mechanism 9 to a suitable position for rolling. The rolling mechanism 9 includes a fixed block 901. The upper surface of the fixed block 901 is fixedly connected to the telescopic rod 8. The inner wall of the fixed block 901 is rotatably connected with a runner 902. The inner wall of the telescopic rod 8 is threadedly connected with a threaded rod 903. The end of the threaded rod 903 is fixedly connected to a rubber plate 904.

[0029] The upper surface of the sliding arm 6 is provided with scale lines 10 for determining the accurate length value of the sliding arm 6 plus the fixed arm 5. The inner wall of the fixed plate 1 is threadedly connected with an extrusion rod 15. The lower surface of the extrusion rod 15 is in contact with the sliding plate 2. There are multiple extrusion rods 15, which can fix the sliding plate 2 and the fixed plate 1. The outer surface of the upper conduit 12 is fixedly connected with two limit rings 14. The two limit rings 14 are respectively located on the upper surface and the lower surface of the rotating ring 3. The limit rings 14 are used to limit the position of the rotating ring 3 to prevent the rotating ring 3 from sliding up and down.

[0030] It should be noted that in actual use of this device, first, the fixed plate 1 is fixed to the upper surface of the tank body by bolts, and the sliding plate 2 is fixed by extruding the sliding plate 2 with the extrusion rod 15, so that the sliding plate 2 is fixed inside the fixed plate 1. When it is necessary to adjust the positions of the lower conduit 11 and the upper conduit 12, turn the extrusion rod 15 to remove the extrusion rod 15 from inside the fixed plate 1, so that the sliding plate 2 can slide flexibly inside the fixed plate 1. Install the fixed arm 5 on one side surface of the connecting plate 4 by bolts, make the telescopic rod 8 press against the side surface of the tank body, drive the sliding arm 6 to move towards the inside of the fixed arm 5 through the tension spring 701, so that the telescopic rod 8 presses against the side surface of the tank body. Observe the position of the end of the fixed arm 5 on the scale line 10 of the sliding arm 6 to obtain the total length of the fixed arm 5 and the sliding arm 6 added together. Push the fixed arm 5 and the sliding arm 6 to rotate around the upper conduit 12, so that the runner 902 rolls around the tank body on the outer surface of the tank body, thereby measuring the angle from the upper conduit 12 as the center to the edge of the tank body in one circle. Observe the position of the end of the fixed arm 5 on the scale line 10 of the sliding arm 6, slide the sliding plate 2, and slide the sliding plate 2 to a suitable position. The sliding plate 2 can be adjusted to the center of the tank body or to a position at a certain distance from the edge of the tank body. Then screw on the extrusion rod 15 to fix the sliding plate 2, the upper conduit 12 and the lower conduit 11, without removing the upper conduit 12, etc., achieving the effect of facilitating the adjustment of the positions of the upper conduit 12 and the lower conduit 11.

[0031] After fixation, the threaded rod 903 can be turned to drive the rubber plate 904 to move closer to the tank body, so that the rubber plate 904 presses against the tank body, thereby fixing the lower end of the telescopic rod 8 to the tank body to prevent the telescopic rod 8 from rotating around the tank body, achieving the effect of preventing the telescopic rod 8 from rotating. According to actual needs, the fixed arm 5 can also be directly removed from the connecting plate 4 to reduce the occupied space and increase practicality. It only needs to be installed again when changing the position of the upper conduit 12 and measuring the distance between the upper conduit 12 and the edge of the tank body, achieving the effect of increasing usability.
