[0002] Double-walled oil tanks refer to three types: SS (superficial), SF (superficial), and FF (superficial). Double-walled tanks are made of two layers of specially designed materials with a continuous space in between, offering safety and environmental friendliness. Double-walled tanks can be anchored underground, reducing the risk of soil and groundwater contamination.

[0003] According to Chinese Patent Publication No. CN 222646762 U, a double-layer underground oil tank for gas stations is disclosed, including a base. A first connecting component is provided on the outer surface of the base, and an adjusting component is fixedly connected to the outer surface of the first connecting component. This invention allows for the selection of different second connecting components and fixing steel bands based on the size of the double-layer oil tank through the connection between the adjusting component and the second connecting component, making it convenient to use.

[0004] The detection of oil leaks is particularly important for double-walled oil tanks during use. Construction personnel also need to conduct regular inspections, maintenance, and checks on the tanks. The existing tanks have welded climbing frames on the outside for easy climbing by construction personnel, but no climbing frames are installed at the manhole opening. Construction personnel need to carry the climbing frames separately and place them at the manhole opening, which reduces the actual usability. Utility Model Content

[0005] The purpose of this utility model is to provide a double-layer underground oil tank for gas stations to solve the problems mentioned in the background art.

[0009] Preferably, the first and second buckles are the same size, both are U-shaped plates, and rectangular slots are formed inside the first and second buckles. The arc-shaped bracket engages with the first and second buckles through the slots.

[0010] Preferably, the output end of the motor extends into the gap between the outer tank and the inner tank and is fixedly connected to the rotating plate. An optical fiber sensor is fixedly installed at the edge of the rotating plate, and a temperature and humidity sensor is also provided on the side of the rotating plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model uses a ladder and climbing frame to facilitate construction workers to climb to the top of the outer tank, reducing the difficulty of maintenance and improving work efficiency. Afterwards, construction workers can remove the clamp from the first clamp on the guardrail and place the clamp in the second clamp, so that the ladder and climbing frame can be installed inside the manhole, making it easier for construction workers to enter the inner tank, enhancing the safety of construction workers and improving the convenience of inspection and access to the inner tank.

[0013] This invention also monitors the stress on the surface of the tank using a fiber optic sensor.

A motor can also be used to rotate the rotating plate, thereby rotating the fiber optic sensor, effectively expanding the detection range of the fiber optic sensor and reducing blind spots. At the same time, it is combined with a pressure sensor to monitor the pressure inside the interlayer, thereby reducing the detection difficulty for construction workers. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5 This utility model provides a technical solution: a double-layer underground oil tank for a gas station, comprising an outer tank body 1, the outer tank body 1 being welded and fixed to the outside of a lifting lug 2, a support plate being provided at the bottom of the outer tank body 1, an oil inlet pipe being provided at the top of the outer tank body 1, an inner tank body 3 being fitted inside the outer tank body 1, a gap being provided between the outer tank body 1 and the inner tank body 3, a drain pipe being fixedly connected to the side of the outer tank body 1, a control valve being provided inside the drain pipe, through which leaked oil in the gap can be discharged, the outer tank body 1 being welded and fixed to a manhole opening 4, the outer side of the manhole opening 4 being connected and fixed to a sealing cover plate 13, the outer tank body 1 being welded and fixed to a guardrail 5 by a fixing frame, and the lifting lug 2 facilitating the hoisting and movement of the entire unit.

[0022] The outer tank body 1 is welded and fixed to the climbing frame 6. The upper surface of the climbing frame 6 is fixedly connected to the handrail. A placement groove 7 is opened on the side of the climbing frame 6. The climbing frame 6 is welded and fixed to the buckle 8. The bottom of the climbing frame 6 is welded and fixed to the support foot 9. The placement groove 7 is adapted to the outer side of the arc-shaped support 10. The arc-shaped support 10 is welded and fixed to the climbing ladder 11. The outer side of the arc-shaped support 10 is welded and fixed to the clamp plate 12. A sealing cover plate 13 is set on the outer side of the manhole 4. The arc-shaped support 10 is welded and fixed to both ends of several linearly arrayed climbing ladders 11. The climbing ladder 11 is an arc-shaped plate. Buckles 8 and 14 are the same size. Buckles 8 and 14 are both U-shaped plates. A rectangular slot is provided inside the 14, and the arc-shaped bracket 10 engages with the first buckle 8 and the second buckle 14 through the slot. Lifting the arc-shaped bracket 10 upwards removes the card plate 12 from the slot of the first buckle 8, thus disassembling the arc-shaped bracket 10. Because the arc-shaped bracket 10 is curved, it can be more easily placed inside the manhole opening 4, expanding the climbing space for construction workers. The convenient disassembly of the arc-shaped bracket 10 effectively enhances the practical use for construction workers, eliminating the need for them to carry an additional ladder. Furthermore, the disassembly of the arc-shaped bracket 10 facilitates placement inside the lifting lug 2, achieving multiple uses for a single ladder.

[0023] The inner wall of the manhole opening 4 is welded and fixed to the buckle 14. The side of the outer tank 1 is connected and fixed to the motor 15 by bolts. The output end of the motor 15 is welded and fixed to the rotating plate 16. A fiber optic sensor 17 and a pressure sensor 18 are fixedly installed on the side of the rotating plate 16.

[0024] The output end of the motor 15 extends into the gap between the outer tank 1 and the inner tank 3 and is welded and fixed to the rotating plate 16. A fiber optic sensor 17 is fixedly installed on the edge of the rotating plate 16, and a temperature and humidity sensor is also installed on the side of the rotating plate 16. The temperature and humidity sensor further enhances the accuracy of oil leakage detection between the outer tank 1 and the inner tank 3. An alarm is installed on the outside of the outer tank 1. When the rotating plate 16 and the fiber optic sensor 17 detect leakage...

[0025] Working Principle: During operation, oil is introduced into the inner tank 3 through the inlet pipe on the outside of the outer tank 1. The stress changes on the outside of the lifting lug 2 are monitored by the fiber optic sensor 17, which detects changes in the reflected light wavelength, thus determining whether the inner wall of the lifting lug 2 is bulging or deformed. The rotating plate 16 is driven by the motor 15, which in turn drives the fiber optic sensor 17 and the pressure sensor 18 to rotate. The rotation of the fiber optic sensor 17 effectively expands the detection range, and in conjunction with the pressure sensor 18, enhances the accuracy of oil leakage detection while reducing the maintenance difficulty for construction personnel.

[0026] During maintenance, construction workers climb onto the guardrail 5 using the arc-shaped bracket 10 and ladder 11. After rotating and opening the sealing cover 13, they lift the arc-shaped bracket 10 upwards to disengage the clamping plate 12 from the slot in the first clamping buckle 8. Then, they place the arc-shaped bracket 10 inside the manhole 4 and insert the clamping plate 12 into the slot inside the second clamping buckle 14, thus connecting and fixing the arc-shaped bracket 10 to the manhole 4, making it easier for construction workers to enter the lifting lug 2.
