If the inner liner leaks, hollow slip ring I and hollow slip ring II are controlled to move closer to the magnetic fluid leakage point, so that hollow slip ring I and hollow slip ring II are located on the upper and lower sides of the leakage point. Then, cooling circulating water is injected into hollow slip ring I and hollow slip ring II. The cooling circulating water cools the area around the magnetic fluid leakage point, reduces the temperature of the magnetic fluid, reduces the fluidity of the magnetic fluid, and reduces the leakage of the magnetic fluid. Thus, the location of the magnetic fluid leakage is initially treated, and the continuous leakage of the magnetic fluid is prevented.

[0016] 2. By installing multiple heaters inside hollow slip ring I and hollow slip ring II, the annular water rings inside hollow slip ring I and hollow slip ring II are heated. The full contact between the annular water rings and the inner liner ensures uniform heating of the inner liner, reduces the viscosity of the magnetic fluid on the inner wall of the liner, increases the fluidity of the magnetic fluid, and allows the magnetic fluid remaining on the inner wall of the liner to flow back after use, reducing the difficulty of subsequent cleaning and making full use of the magnetic fluid, thus saving production costs for the enterprise.

[0017] 3. By installing fans inside hollow slip ring I and hollow slip ring II, the air flow between the outer shell and the inner liner is driven, which accelerates the evaporation of moisture trapped in the inner liner, thereby achieving heat dissipation of the inner liner and preventing the inner liner from overheating and causing deterioration of the magnetic fluid.

[0029] The outer wall of the inner liner 4 is coated with a graphene coating to reduce the accumulation of static electricity generated by friction with the inner liner 4, thereby reducing the risk of fire and explosion caused by static electricity.

[0030] The hollow slip ring I9 has a groove on the side facing the inner liner 4, and its longitudinal section is C-shaped.

[0031] It also includes a diversion pipe 10, branch pipe I11, sleeve I12, and waste discharge pipe 13; the upper part of the outer shell 2 is connected to the diversion pipe 10; the diversion pipe 10 is connected to four equally spaced branch pipes I11; the branch pipes I11 are telescopic flexible hoses; the hollow slip ring I9 is ​​connected to all the branch pipes I11; the lower part of the outer shell 2 is fixedly connected to the sleeve I12; the discharge pipe 6 is slidably connected to the sleeve I12; the inside of the sleeve I12 is hollowed out, and several waste discharge ports 1201 are opened on the upper outer wall, and the waste discharge ports 1201 are all located inside the outer shell 2; the lower part of the sleeve I12 is connected to the waste discharge pipe 13; the waste discharge pipe 13 is fixedly connected to the fixed frame 1; the diversion pipe 10 has two main channels, one of which is responsible for water inlet, and the other is responsible for draining water after the branch pipes I11 and the hollow slip ring I9 are filled, so as to realize the cooling water circulation.

[0032] The lower part of the outer shell 2 is a bowl-shaped part 2001, which is used to concentrate the position of the liquid guide sleeve I12 so that the liquid can fully enter the waste outlet 1201.

[0033] The outer surface of the discharge pipe 6 is coated with a nano-ceramic coating to reduce wear on the discharge pipe 6 and the sleeve I12.

[0034] It also includes an electric slider II14, a hollow slip ring II15, and a branch pipe II16; each electric guide rail 7 is also slidably connected to an electric slider II14; all electric sliders II14 are fixedly connected to a hollow slip ring II15; the hollow slip ring II15 has a groove on the side facing the inner liner 4, and its longitudinal section is C-shaped; the hollow slip ring II15 is equipped with a temperature sensor and an ultrasonic detector; the hollow slip ring II15 is connected to several branch pipes II16, and the branch pipes II16 are flexible hoses; all branch pipes II16 are connected to the hollow slip ring I9.

[0035] The working steps of the above embodiments are as follows:

[0036] In existing technologies, to avoid soil and groundwater contamination after magnetofluid leakage, storage equipment is generally designed with a double-layer structure. The inner liner 4 is first inspected for defects to prevent leakage after the magnetofluid is injected, which would otherwise require significant manpower and resources to eliminate the leak and result in material loss. First, all electric sliders I8 and II14 are controlled to move downwards on their connected electric guide rails 7, simultaneously driving hollow slip rings I9 and II15 downwards. The ultrasonic detectors inside the hollow slip rings I9 and II15 move downwards along with them, inspecting the inner liner 4 for defects. Once the height of the hollow slip ring II15 is below the bottom surface of the inner liner 4, all electric sliders I8 and II14 are reset, simultaneously driving the hollow slip rings I9 and II15 to reset. During normal self-testing, the hollow slip rings I9 and II15 are positioned such that... 15. Each component only needs to complete half the height of the inner liner 4 to effectively improve self-inspection efficiency. The self-inspection process stops at this point, and the self-inspection results are transmitted to the computer for recording via wires. When the computer indicates that the inner liner 4 is intact, the control valve of the discharge pipe 6 is closed, and the control valve of the inlet pipe 5 is opened. Then, the magnetic fluid is injected into the inner liner 4 through the inlet pipe 5. The inner liner 4 is connected to the outer shell 2 by the upper and lower elastic elements 3, so that the inner liner 4 is suspended inside the outer shell 2. Thus, when the magnetic fluid is injected into the inner liner 4, the magnetic fluid impacts the inner liner 4, and the upper and lower elastic elements 3 can buffer the impact on the inner liner 4. Then, the pressure sensor on the lower elastic element 3 monitors the weight of the injected magnetic fluid in the inner liner 4 in real time. Then, the liquid level of the magnetic fluid is calculated by converting the proportional coefficient and the density of the magnetic fluid, so as to avoid excessive injection of magnetic fluid and leakage of magnetic fluid in the inner liner 4. After storing a predetermined amount, the injection of magnetic fluid is stopped, and the inlet pipe 5 is closed.

[0037] The inspection is not limited to a single pre-use test; the inner tank 4 needs to be inspected frequently during use to ensure it is leak-free. Connect the diversion pipe 10 to the circulating water system and control all electric sliders I 8 and II 14 to move downwards synchronously, simultaneously driving hollow slip rings I 9 and II 15 downwards. If the ultrasonic detectors on the hollow slip rings II 15 and I 9 detect any leakage in the inner tank 4, the ultrasonic detectors upload the detection results to the computer and control the hollow slip rings II 15... The hollow slip ring I9 is ​​moved to the upper and lower sides of the leakage location in the inner liner 4, respectively. Then, circulating water is diverted through the branch pipe 10 to each branch pipe I11 with elastic expansion capacity. The circulating water then enters the hollow slip ring I9, and the circulating water in the hollow slip ring I9 enters the hollow slip ring II15 through the branch pipe II16, until both the hollow slip ring II15 and the hollow slip ring I9 are filled with water. This allows the branch pipe 10 to inject cold water into the hollow slip rings II15 and I9. Both the hollow slip rings II15 and I9 have grooves on the side facing the inner liner 4. The longitudinal sections of hollow slip ring II15 and hollow slip ring I9 are C-shaped, thus forming an annular water ring against the inner liner 4. Cooling water cools both sides of the leaking area of ​​the inner liner 4, reducing the flow rate of the magnetofluid at the leak point, decreasing its velocity, and reducing leakage. Furthermore, the positions of hollow slip rings II15 and I9 remain unchanged, confining the leaked magnetofluid to the area between them. This allows for timely initial treatment of the leak in the inner liner 4, effectively reducing... The magnetic fluid continued to leak, and circulating water was effectively prevented from entering the inner tank 4 through the leak point and contaminating the magnetic fluid. After the maintenance personnel arrived at the scene, they released the magnetic fluid in the inner tank 4 to the backup storage tank by opening the control valve of the discharge pipe 6. Then, based on the leakage situation of the storage tank, a maintenance plan for this storage equipment was determined. After the magnetic fluid was transferred, all electric sliders I8 and II14 were controlled to continue to descend, synchronously driving the hollow slip rings II15 and I9 to descend until the C-shaped groove of the hollow slip ring II15 was no longer blocked by the inner tank 4. Figure 6 As shown, in the A-path of the liquid flow, the liquid in the hollow slip ring II 15 flows out to the bowl-shaped part 2001, and then the liquid in the hollow slip ring I 9 also enters the hollow slip ring II 15 through the branch pipe II 16, and then flows out to the bowl-shaped part 2001. The circulating water then gathers in the middle of the bowl-shaped part 2001 from the liquid flowing out of the hollow slip ring II 15, and enters the sleeve I 12 through the waste discharge port 1201. Then, by opening the control valve of the waste discharge pipe 13, the liquid in the sleeve I 12 can be discharged and collected in the waste liquid tank for subsequent treatment.

[0038] Second embodiment

[0039] Based on the first embodiment, according to Figures 1-2 and Figure 4-Figure 6 As shown, it also includes a heater 101; several heaters 101 are installed in the C-shaped grooves of hollow slip ring I9 and hollow slip ring II15 respectively; the heater 101 is a heating wire.

[0040] It also includes a blower 102 and a sleeve II 103; four blowers 102 are installed on each of the hollow slip ring I 9 and the hollow slip ring II 15; four through holes are opened on each of the hollow slip ring I 9 and the hollow slip ring II 15, and each blower 102 is located above one through hole; the upper part of the outer shell 2 is fixedly connected to the sleeve II 103; the sleeve II 103 is slidably connected to the feed pipe 5; two exhaust pipes 10301 are provided in the sleeve II 103; and an air inlet pipe 1202 is provided in the sleeve I 12.

[0041] Both the exhaust pipe 10301 and the intake pipe 1202 are designed in a spiral shape to reduce magnetic leakage.

[0042] The working steps of the above embodiments are as follows:

[0043] Based on the first embodiment, and considering that the magnetic fluid is greatly affected by temperature, its viscosity decreases as the temperature rises, facilitating its flow, while its viscosity increases as the temperature falls, making it more viscous. Therefore, when the ambient temperature is low, the magnetic fluid's viscosity is high, and it tends to adhere to the inner wall of the inner liner 4 when used. Temperature sensors within hollow slip rings I and II monitor the temperature of the inner liner 4 in real time. When the ambient temperature is low and magnetic fluid needs to be used, the fluid level in the inner liner 4 drops, leaving residual magnetic fluid on the inner wall. At this time, water is injected into hollow slip rings I and II, and simultaneously, heater 101 is activated. After heating the annular water rings inside hollow slip ring I9 and hollow slip ring II15, the annular water rings make full contact with the inner liner 4, thus ensuring that the inner liner 4 is heated evenly on the same horizontal plane. This reduces the viscosity of the magnetic fluid on the inner wall of the inner liner 4, increases the fluidity of the magnetic fluid, and causes the magnetic fluid to flow downwards, effectively reducing the amount of magnetic fluid remaining on the inner wall of the inner liner 4. Then, the hollow slip rings I9 and II15 are controlled to slide downwards along the inner liner 4, achieving heating of the inner liner 4 from top to bottom. This allows the magnetic fluid adhering to the inner wall of the inner liner 4 to begin flowing downwards after being heated, causing the residual magnetic fluid on the inner wall of the inner liner 4 to flow back into the magnetic fluid body. This reduces the difficulty of subsequent cleaning of the inner wall of the inner liner 4 and reduces the waste of magnetic fluid, saving production costs for the enterprise.

[0044] Continuing with the above work, high temperature can increase the fluidity of the magnetofluid and reduce viscosity. However, excessively high temperatures can also cause the magnetofluid to deteriorate and affect its magnetic properties. Therefore, when the ambient temperature is high, the hollow slip rings I9 and II15 are still used to slide along the inner liner 4. Water is injected into the hollow slip rings I9 and II15 to form two annular water rings. As the annular water rings slide along the inner liner 4, a small amount of water will remain on the outer wall of the inner liner 4, continuously supplying circulating water. Corresponding through holes are opened on the hollow slip rings I9 and II15, and a fan 102 is installed at the position of the through holes. During the downward sliding of the hollow slip rings I9 and II15, the fan 102 is activated. The fan 102 forces the air to flow between the outer shell 2 and the inner liner 4. Outside air enters the outer shell 2 through the air inlet pipe 1202, and then, under the rotation of the fan 102, the air is driven to flow upward through the through holes, such as... Figure 6 As shown in the airflow path B, the upward airflow accelerates the evaporation of moisture trapped on the outer wall of the inner liner 4 and carries the moisture further upward. Since the evaporation of moisture in the inner liner 4 requires heat absorption, this achieves heat dissipation for the inner liner 4, preventing the temperature of the inner liner 4 from becoming too high and causing deterioration of the magnetic fluid. Then, the air reaches the upper part of the outer shell 2 and is discharged to the outside through the exhaust pipe 10301. In this way, the air circulation achieves heat dissipation for the inner liner 4, ensuring the stability of the magnetic fluid. The spiral air inlet pipe 1202 and the exhaust pipe 10301 prevent magnetic leakage when outside air is introduced into the outer shell 2.
