Detailed implementation manners
[0023] In the embodiments of the present application, by providing an inner floating disc with a monitoring function, it effectively solves the problem that when liquid leakage starts around the inner floating disc, the buoyancy originally relied on by the inner floating disc will gradually decrease.

When the liquid in the storage tank decreases again, the inner floating disc body squeezes to compress the piston rod, and the pressure detected by the pressure sensor gradually increases. The remaining liquid in the storage tank can be roughly calculated, thus achieving the function of detecting the approximate liquid in the storage tank. Embodiment
[0024] Such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, the technical solution in the embodiment of the present application effectively solves the above-mentioned technical problem that when liquid leakage starts around the internal floating roof, the buoyancy originally relied on by the internal floating roof will gradually decrease. If the internal floating roof is not stopped in time, it will gradually sink to the bottom of the storage tank, thus losing its original meaning. The general idea is as follows: An internal floating roof with a monitoring function includes an internal floating roof body 11. A stop mechanism is provided at the top of the internal floating roof body 11. The stop mechanism includes a second mounting seat 16, a rotating column 17, a first disc 18, a first torsion spring 19, a second torsion spring 21, a second disc 22, and a clamping block 23. The rotating column 17 is rotatably installed inside the second mounting seat 16. The first disc 18 is fixedly installed on the side wall of the rotating column 17. The first torsion spring 19 is sleeved on the side wall of the rotating column 17, and the first torsion spring 19 is fixedly installed with the first disc 18. One end of the first torsion spring 19 away from the first disc 18 is fixedly installed with the second mounting seat 16. The second disc 22 is fixedly installed on the side wall of the rotating column 17. The second torsion spring 21 is sleeved on the side wall of the rotating column 17, and the second torsion spring 21 is fixedly installed with the second disc 22. One end of the second torsion spring 21 away from the second disc 22 is fixedly installed with the second mounting seat 16.

A floating plate 13 is fixedly installed on the top of the telescopic column 12. A first mounting seat 14 is fixedly installed on the bottom of the floating plate 13. A plugging rod 15 is rotatably installed inside the first mounting seat 14. The plugging rod 15 is plugged inside the rotating column 17. When the internal floating roof body 11 descends and the liquid touches the liquid level sensor 27, an alarm is issued. The floating plate 13 will float accordingly. The floating plate 13 drives the telescopic column 12 to extend. The floating plate 13 drives the first mounting seat 14 to move from bottom to top. The first mounting seat 14 drives the plugging rod 15 to flip from the periphery to the middle. The plugging rod 15 disengages from the inside of the rotating column 17. At this time, the second torsion spring 21 and the first torsion spring 19 release the torsional force, driving the second disc 22 and the first disc 18 to rotate counterclockwise. The second disc 22 and the first disc 18 drive the rotating column 17 to rotate counterclockwise. The rotating column 17 drives the clamping block 23 to rotate counterclockwise. The clamping block 23 will contact the inner wall of the storage tank, increasing the friction force. The friction force is used to supplement the buoyancy, thereby achieving the function of preventing the internal floating roof body 11 from sinking.
[0025] A circular groove 26 is opened inside the internal floating roof body 11 and is sleeved on the side wall of the iron column inside the storage tank to prevent the internal floating roof body 11 from rotating.

A support plate 29 is fixedly installed at the bottom of the piston rod 28. A pressure sensor 31 is fixedly installed inside the support plate 29. When the liquid in the storage tank gradually drops, the inner floating disc body 11 will drop along with the liquid. The support plate 29 will come into contact with the bottom of the storage tank first, and the pressure sensor 31 will be subjected to pressure. When the liquid in the storage tank decreases again, the inner floating disc body 11 squeezes to compress the piston rod 28, and the pressure detected by the pressure sensor 31 gradually increases. The remaining liquid inside the storage tank can be roughly calculated, so as to achieve the function of detecting the approximate liquid in the storage tank.
[0027] Aiming at the problems existing in the prior art, the utility model provides an inner floating disc with a monitoring function. The inner floating disc body 11 will drop. When the liquid touches the liquid level sensor 27, an alarm will be issued. The floating plate 13 will float accordingly, driving the telescopic column 12 to extend.

The plugging rod 15 disengages from the inside of the rotating column 17. At this time, the second torsion spring 21 and the first torsion spring 19 release the torsional force, driving the second disc 22 and the first disc 18 to rotate counterclockwise. The second disc 22 and the first disc 18 drive the rotating column 17 to rotate counterclockwise. The rotating column 17 drives the clamping block 23 to rotate counterclockwise. The clamping block 23 will contact the inner wall of the storage tank, increasing the friction force. The friction force is used to supplement the buoyancy, so as to achieve the function of preventing the inner floating disc body 11 from sinking. When the liquid in the storage tank gradually drops, the inner floating disc body 11 will drop along with the liquid. The support plate 29 will come into contact with the bottom of the storage tank first, and the pressure sensor 31 will be subjected to pressure. When the liquid in the storage tank decreases again, the inner floating disc body 11 squeezes to compress the piston rod 28, and the pressure detected by the pressure sensor 31 gradually increases. The remaining liquid inside the storage tank can be roughly calculated, so as to achieve the function of detecting the approximate liquid in the storage tank.

When the liquid in the storage tank decreases again, the inner floating disc body 11 squeezes to compress the piston rod 28, and the pressure detected by the pressure sensor 31 gradually increases. The remaining liquid inside the storage tank can be roughly calculated, so as to achieve the function of detecting the approximate liquid in the storage tank.
[0030] Second step, when there is liquid seepage on the side wall of the inner floating disc body 11, the buoyancy of the inner floating disc body 11 will become smaller, and the inner floating disc body 11 will descend. When the liquid touches the liquid level sensor 27, an alarm will be issued. The floating plate 13 will float accordingly, the floating plate 13 will drive the telescopic column 12 to extend, the floating plate 13 will drive the first mounting seat 14 to move upward from bottom to top, the first mounting seat 14 will drive the plugging rod 15 to flip from the periphery to the middle, and the plugging rod 15 will disengage from the inside of the rotating column 17. At this time, the second torsion spring 21 and the first torsion spring 19 will release the torsional force, drive the second disc 22 and the first disc 18 to rotate counterclockwise, the second disc 22 and the first disc 18 will drive the rotating column 17 to rotate counterclockwise, the rotating column 17 will drive the clamping block 23 to rotate counterclockwise, and the clamping block 23 will contact the inner wall of the storage tank, increasing the friction force. The friction force is used to replace the buoyancy, so as to achieve the function of preventing the inner floating disc body 11 from sinking.
