Description

Technical Field

[0001] The utility model relates to the technical field of oil tanks, in particular to a double-layer oil tank with leak-proof detection performance. Background Art

[0002] Double-layer oil tanks include SS, SF, and FF. SF stands for Steel-Reinforced Fiberglass Double-Layer Oil Storage Containers. These are single-layer steel tanks with a glass fiber reinforced plastic (FRP) outer layer attached to create a double-layer structure. There's a through-hole between the steel inner tank and the FRP outer tank. FF stands for Glass Fiber Reinforced Plastic Double-Layer Oil Tank. Both the inner and outer layers are made of glass fiber reinforced plastic, with a through-hole in between. They're also equipped with a leak detection device that monitors the gap 24 hours a day. If a leak occurs in either the inner or outer tank, the leak detection sensor detects the liquid level at the bottom of the gap and sounds an alarm, ensuring safe use of the tank.

[0003] When the leakage detection device is in use, the sensing probe needs to be maintained regularly to ensure the sensitivity and accuracy of the sensing probe. The leakage detection device is fixed to the double-layer oil tank through a flange. When maintaining the sensing probe, the connecting flange needs to be disassembled first, and then the sensing probe can be taken out from the gap between the inner tank and the outer tank. Currently, the flanges are fixed together by multiple bolts, which makes disassembly and installation troublesome and requires specific tools to remove the bolts, which is inconvenient for maintenance of the sensing probe. Therefore, in response to the above problems, a double-layer oil tank with leak-proof detection performance is proposed. Utility Model Content

[0024] As a further improvement of the present invention, Figure 2 、 Figure 4 and Figure 5 As shown, the retracting and extending mechanism includes a rotating core 7 rotatably connected to the connecting cylinder 5, and the rotating core 7 is fixedly connected to the end cover 6. The inner side of the rotating core 7 is rotatably connected to a first roller 11 and a second roller 16. The cable 9 is located between the first roller 11 and the second roller 16. The outer side of one end of the first roller 11 is fixedly connected to a first gear ring 12. One end of the first gear ring 12 is meshed with a second gear ring 17, and the second gear ring 17 is fixedly connected to the second roller 16. One end of the first roller 11 is fixedly connected to a connecting block 13. When the sensing probe 10 needs to be maintained, the sensing probe 10 is retracted into the inner side of the rotating core 7 by the friction between the first roller 11 and the second roller 16 and the cable 9. Then, the rotating core 7 is rotated, and the sensing probe 10 is rotated to the side of the operating slot 19 by the rotating core 7. Then, the sensing probe 10 is taken out through the operating slot 19. There is no need to use tools to remove the fixing bolts between the first flange 3 and the second flange 4. The operation is simple, which facilitates the staff to detect the sensing probe 10.

[0025] As a further improvement of the present invention, Figure 2 、 Figure 3 As shown, one end of one of the end covers 6 is movably connected to a first handle 15, and the other end of the first handle 15 is fixedly connected to a sleeve 14 that can be engaged with the connecting block 13.

The staff then rotates the rotating core 7 through the second handle 18. The rotating core 7 then rotates together with the sensing probe 10 through the first roller 11 and the second roller 16, so that the sensing probe 10 is rotated to the side of the operating slot 19. The sensing probe 10 is then taken out for maintenance through the operating slot 19. There is no need to use tools to remove the fixing bolts between the first flange 3 and the second flange 4. The operation is simple, which facilitates the staff to detect the sensing probe 10.
