Description

Technical Field

[0001] The utility model belongs to the technical field of double-layer oil tanks, and in particular relates to a double-layer underground oil tank for a gas station. Background Art

[0002] Double-layer oil tanks refer to SS oil tanks, SF oil tanks, and FF oil tanks, all of which are composed of an inner layer, an outer layer, and a through gap. Traditional single-layer steel oil tanks are buried underground and are in an internal and external corrosive environment for a long time, which makes them prone to leakage, thus causing soil and groundwater pollution accidents. Therefore, double-layer oil tanks are needed.

[0003] A FF double-layer gas station buried oil tank is disclosed in Chinese patent CN220333645U, which belongs to the technical field of FF double-layer oil tanks.

[0004] It is not easy to fix a general double-layer oil tank under the ground. After long-term use, it may become loose, posing a safety hazard. If the inside of the tank cannot be inspected, leakage may not be discovered in time. In the above document, the ground anchor assembly and the fixing assembly are fixed together with the embedded parts respectively, and the entire FF double-layer oil tank is completely fixed with the straps. However, when connecting the ground anchor assembly with the straps, the straps are tied to the outer shell of the double-layer oil tank. However, due to the different models and sizes of double-layer oil tanks, there will be a problem that the straps cannot be connected to the ground anchor assembly. It is necessary to select the appropriate straps and ground anchor assembly according to the size of the double-layer oil tank for fixing, which is more troublesome.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

When the fixed steel belt 5 is located on a double-layer oil tank 6 with a larger size, even if the fixed steel belt 5 is located relatively high, it can be connected to the fixed steel belt 5 by moving the second connecting component 4. There is no need to select different second connecting components 4 and fixed steel belts 5 according to the size of the double-layer oil tank 6. The utility model has certain versatility and is relatively convenient to use.

[0036] After the square plate 201 is fixed in the square groove 202, the screw 301 on the square plate 201 passes through the square groove 202 and extends to the top of the base 1. The screw barrel 302 is rotated and moved on the surface of the screw barrel 301. The screw barrel 302 can drive the second connecting component 4 to move.
