Description

Technical Field

[0001] This utility model relates to the field of instrumentation technology, specifically to a magnetic float level gauge that is easy to install. Background Technology

[0002] Currently, magnetic float level gauges consist of two parts: a field indicating section and auxiliary devices (level control switch and level remote transmitter). Users can also select this instrument separately for level detection in various towers, tanks, troughs, spherical containers, and boilers. This series of level gauges offers high sealing, leak-proof performance, and suitability for high-temperature, high-pressure, and corrosion-resistant applications. However, the existing installation method involves fixing the float chamber to the container being measured via a flange. Since the float chamber cannot be pre-fixed, workers must manually straighten it during installation, causing significant inconvenience. Therefore, there is an urgent need to design a more easily installed magnetic float level gauge to solve these problems. Chinese patent document CN211317475U discloses a magnetic float level gauge that is easy to install, including a float chamber, connecting pipes, and flanges. Two connecting pipes are each located on one side of the float chamber, and two flanges are welded to the ends of the two connecting pipes furthest from the float chamber. A sleeve is slidably connected to the center of the float chamber near the flanges. Before installing the float chamber, the flanges are aligned with the installation position, and then the float chamber is attracted to the outer wall of the container to be measured by a permanent magnet. This allows the operator to perform the flange installation step with both hands, saving time and effort. The previous method involved manually holding the float chamber during installation. During installation, the float chamber was pushed towards the container to be measured, and the insert rod pressed the spring through the pressure plate, allowing the flange to align successfully with the flange structure of the container. After installation, the spring tended to push outwards to both sides, further reinforcing the float chamber and effectively preventing it from wobbling. However, even with the flange aligned with the installation position and the float chamber attached to the outer wall of the container by a permanent magnet, the device still exhibited some wobbling and instability. Therefore, we propose a magnetic float level gauge that is easy to install. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1: Please see Figure 1-4 and Figure 7 This utility model provides a technical solution: a magnetic float level gauge that is easy to install, including a magnetic block 1, a U-shaped clamping plate 2 fixedly connected to the rear end of the magnetic block 1, a threaded hole 8 opened at the right end of the U-shaped clamping plate 2, a screw 6 engaged in the inner cavity of the threaded hole 8, a fixing block 7 fixedly provided on the outer surface of the screw 6 and the inner cavity of the U-shaped clamping plate 2, a connecting mechanism 3 fixedly connected to the front end of the fixing block 7, a quick-connect assembly 4 provided on the front side of the connecting mechanism 3, and a level gauge body 5 fixedly connected to the front end of the quick-connect assembly 4. By adding the magnetic block 1, the connecting mechanism 3 can be attracted to the outer wall of the container to be measured with the cooperation of the U-shaped clamping plate 2, the screw 6 and the fixing block 7.

[0016] A mounting groove 33 is provided in the middle of the lower end of a rectangular plate 31. A pull rod 34 is slidably connected to the inner cavity of the mounting groove 33. Three L-shaped locking pins 36 are fixedly connected to the front side of the outer surface of the pull rod 34. A spring 32 is provided on the lower side of the outer surface of the pull rod 34 and the lower side of the inner cavity of the mounting groove 33. Three slots 37 are provided in the middle of the front end of the rectangular plate 31. The inner cavities of the three slots 37 communicate with the inner cavity of the mounting groove 33. Connecting assemblies 35 are fixedly connected to the upper and lower sides of the rear end of the rectangular plate 31. The upper ends of the three L-shaped locking pins 36 are respectively... The bottom wall of the inner cavity of the three L-shaped locking pins 36 is not penetrated. The middle of the rear end of the rectangular plate 31 is fixedly connected to the front end of the fixing block 7. The quick-connect assembly 4 includes a rectangular plate 41. The rear end of the rectangular plate 41 is fixedly connected to three locking blocks 42. The middle of the upper end of each of the three locking blocks 42 is fixedly connected to a through hole 43. The outer surface of the three locking blocks 42 is slidably connected to the inner cavity of the three locking slots 37 respectively. The inner cavity of the three through holes 43 is slidably connected to the upper side of the outer surface of the three L-shaped locking pins 36 respectively. The front end of the rectangular plate 41 is fixedly connected to the rear end of the liquid level gauge body 5.

[0017] First, align the two connecting assemblies 35 with the mounting positions of the upper and lower flanges of the container to be tested, and simultaneously attach the magnetic block 1 to the outer wall of the container. At this point, the rectangular plate 31 is stable and does not wobble in the vertical direction. Next, use bolts to fix the connecting assemblies 35 to the upper and lower flanges of the container to be tested. Then, pull the pull rod 34, causing it to slide downward in the inner cavity of the mounting groove 33. While compressing the spring 32, the three L-shaped locking pins 36 also slide downward, so that the upper ends of the three L-shaped locking pins 36 are flush with the bottom wall of the inner cavity of the three locking slots 37. Then, the rectangular plate 41 is moved to move the rectangular plate 41. Three locking blocks 42 are respectively locked in the inner cavity of the three locking slots 37. At this moment, the pull rod 34 is released and pushed upward by the elastic force of the spring 32. The movement of the pull rod 34 simultaneously drives the upper ends of the three L-shaped locking pins 36 to pass through the inner cavity of the three through holes 43, thereby fixing the rectangular plate 41 and achieving the purpose of quick installation of the liquid level gauge body 5. It should be noted that the quick-connect assembly 4 and the liquid level gauge body 5 are an integral unit. When the liquid level gauge body 5 needs to be replaced, the pull rod 34 is pulled down to disengage the quick-connect assembly 4 from the connecting mechanism 3, and the quick-connect assembly 4 and the liquid level gauge body 5 can be replaced as a whole.

[0018] Example 2: Please see Figure 5-6This utility model provides a technical solution: a magnetic float level gauge that is easy to install. Both connecting groups 35 include connecting rods 351. A cylinder 355 is fixedly connected to the middle of the rear end of each of the two connecting rods 351. A rectangular rod 354 is fixedly connected to the rear end of each of the two cylinders 355. A fan-shaped cover 352 is slidably connected to the outer surface of each of the two rectangular rods 354. A flange 353 is fixedly connected to the rear end of each of the two rectangular rods 354. The front ends of the two connecting rods 351 are fixedly connected to the upper and lower sides of the rear end of the rectangular plate 31, respectively. The inner cavities of the two fan-shaped covers 352 are slidably connected to the outer surfaces of the two flanges 353, respectively.

[0019] With the magnetic block 1 adsorbed onto the outer wall of the container to be tested, the two flanges 353 are aligned with the upper and lower flanges of the container to be tested, respectively. Then, the sector-shaped cover 352 is pushed to slide backward on the outer surface of the rectangular rod 354, so that the sector-shaped cover 352 is locked onto the upper surface of the upper and lower flanges of the container to be tested. Then, the flanges 353 and the flanges can be fixed with bolts. During the tightening of the bolts, in order to prevent the sector-shaped cover 352 from affecting the fixing of the bolts, after the flanges 353 and the flanges are fixed with bolts on the lower side, the sector-shaped cover 352 is pushed forward on the outer surface of the rectangular rod 354 and slides onto the outer surface of the cylinder 355. Then, the sector-shaped cover 352 is rotated to the lower side so that it does not affect the fixing of the upper side of the flanges 353 to the flanges with bolts.
