Description

Technical Field

[0001] The utility model relates to the field of liquid level gauges, and specifically to a novel magnetic flap liquid level gauge. Background Art

[0002] A flap liquid level gauge, also known as a magnetic liquid level gauge, a magnetic turning column liquid level gauge, and a magnetic float liquid level gauge, is a liquid level detection instrument that works based on the principle of magnetic coupling. The working principle of the flap liquid level gauge is based on the fact that the float floats up and down with the change of the liquid level. A magnet is arranged inside the float. As the float rises and falls, the magnet on the float causes the external flap display to flip, thereby vividly displaying the liquid level height. The change of the flap color interface only depends on the position of the float and is not affected by the medium pressure, and is suitable for on-site liquid level measurement.

[0003] During the use process, impurities are likely to accumulate on the inner wall of the liquid level gauge cavity. As the use time increases, the impurities accumulated on the inner wall of the liquid level gauge cavity will become thicker, affecting the floating of the magnetic float, and it is relatively inconvenient to clean the impurities accumulated on the inner wall of the liquid level gauge cavity.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figure 1 , Figure 2 and Figure 3 shown, the present utility model provides a technical solution for a new magnetic flap liquid level gauge, including a liquid level gauge cavity 2, a magnetic indicating flap 3 and a flange 4 are connected to the liquid level gauge cavity 2, a plug 1 is provided at the upper end of the liquid level gauge cavity 2, a drain valve 5 is provided at the lower end of the liquid level gauge cavity 2, a magnetic float 6 is provided in the liquid level gauge cavity 2, a limit protrusion 7 is fixedly installed at the bottom of the liquid level gauge cavity 2, a cleaning mechanism 8 is provided at the bottom of the magnetic float 6, a driving mechanism 9 is connected to the threaded connection sleeve 802, and by the coordinated use of the driving mechanism 9 and the cleaning mechanism 8, the inside of the liquid level gauge cavity 2 can be quickly cleaned.

[0023] As Figure 3 and Figure 4 shown, the cleaning mechanism 8 includes a first cylinder 807 fixedly installed at the bottom of the magnetic float 6, a driving piston 806 is movably installed in the first cylinder 807, a telescopic arm 805 is fixedly installed on the driving piston 806, a cleaning scraper 804 is fixedly installed at the end of the telescopic arm 805, a threaded connection sleeve 802 is fixedly installed at the upper end of the magnetic float 6, a guiding cone 801 is fixedly installed at the upper end of the threaded connection sleeve 802, a connecting pipe 803 is provided in the magnetic float 6, one end of the connecting pipe 803 is connected to the first cylinder 807, and the other end of the connecting pipe 803 is connected to the inside of the threaded connection sleeve 802.

[0024] Specifically, the driving piston 806 can drive the telescopic arm 805 to extend. After the telescopic arm 805 extends, the cleaning scraper 804 will adhere to the inner wall of the liquid level gauge cavity 2. When the cleaning scraper 804 adheres to the inner wall of the liquid level gauge cavity 2, it can drive the cleaning scraper 804 to move up and down through the hollow driving rod 901, so as to quickly clean the inside of the liquid level gauge cavity 2.

[0025] As Figure 3 and Figure 5 As shown, the driving mechanism 9 includes a hollow driving rod 901 connected in the threaded connection sleeve 802. A butt joint thread 906 is provided at the lower end of the hollow driving rod 901. A second cylinder body 904 is fixedly installed at the upper end of the hollow driving rod 901. A control piston 905 is movably installed in the second cylinder body 904. A driving screw rod 903 is installed on the second cylinder body 904. A rotating connection seat 902 is fixedly installed on the control piston 905. The lower end of the driving screw rod 903 is rotationally connected to the control piston 905 through the rotating connection seat 902.

[0026] Specifically, after the lower end of the hollow driving rod 901 is connected in the threaded connection sleeve 802, the hollow driving rod 901 can be rotated, so as to tighten the hollow driving rod 901 in the threaded connection sleeve 802. And the control piston 905 can be driven to move up and down through the driving screw rod 903. When the control piston 905 moves up and down, it can control the gas in the second cylinder body 904 to enter the first cylinder body 807, so as to control the telescopic movement of the telescopic arm 805, facilitating the user to control whether the cleaning scraper 804 works.

[0027] Working principle: When in use, the liquid in the container to be measured can be discharged. After the liquid in the container to be measured is discharged, the magnetic float 6 will drop to the bottom of the liquid level gauge cavity 2. After the magnetic float 6 drops to the bottom of the liquid level gauge cavity 2, the plug 1 can be opened. After the plug 1 is opened, the hollow drive rod 901 can be inserted into the liquid level gauge cavity 2, and the lower end of the hollow drive rod 901 is connected to the threaded connection sleeve 802. After the lower end of the hollow drive rod 901 is connected to the threaded connection sleeve 802, the hollow drive rod 901 can be rotated, so as to tighten the hollow drive rod 901 in the threaded connection sleeve 802. After the hollow drive rod 901 is tightened in the threaded connection sleeve 802, the drive screw 903 can be rotated downward. After the drive screw 903 is rotated downward, it will drive the control piston 905 to move downward, so as to squeeze the gas in the second cylinder 904 into the first cylinder 807, making the drive piston 806 in the first cylinder 807 move forward. After the drive piston 806 in the first cylinder 807 moves forward, the telescopic arm 805 will extend, making the cleaning scraper 804 adhere to the inner wall of the liquid level gauge cavity 2. Then, the cleaning scraper 804 can be driven to move up and down by the hollow drive rod 901 to clean the inside of the liquid level gauge cavity 2. After the cleaning is completed, the drive screw 903 can be rotated upward to make the control piston 905 move upward, so as to suck out the gas in the first cylinder 807 and reset the cleaning scraper 804. Then, the magnetic float 6 can be moved to the lower end of the liquid level gauge cavity 2. At this time, the limit protrusion 7 will block one side of the telescopic arm 805. After the limit protrusion 7 blocks one side of the telescopic arm 805, the hollow drive rod 901 can be rotated in the reverse direction, so that the hollow drive rod 901 is disengaged from the threaded connection sleeve 802.
