Description

Technical Field

[0001] This utility model relates to the field of oil storage equipment technology, and in particular to a double-walled oil tank with leak detection. Background Technology

[0002] Double-walled oil tanks typically refer to oil storage tanks consisting of two layers of tank bodies. They are mainly used for storing and transporting hazardous chemicals such as gasoline and diesel. The outer tank body is usually made of steel or other corrosion-resistant materials, while the inner tank body is used for actual storage. The main purpose of this design is to enhance the safety of the tank, because even if the inner tank body is damaged, the outer tank body can still provide temporary isolation to prevent the leakage of hazardous substances. Therefore, double-walled oil tanks with side leak detection are widely used.

[0003] Chinese patent provides a double-walled oil tank, publication number CN221738842U, including an outer shell, the inner wall of which is provided with a vacuum partition; a protective mechanism, which can protect the double-walled oil tank and improve its safety, is provided on the inner wall of the outer shell; wherein, the protective mechanism includes an inner shell provided on the inner wall of the vacuum partition, the inner wall of the vacuum partition is fixedly connected with several evenly distributed fixing rings, the inner wall of the fixing rings is provided with mounting rings, and the outer wall of the outer shell is provided with mounting components.

[0004] The aforementioned oil tank can be protected by a combination of reinforcing plates and protective plates. A protective sleeve is placed between the inner shell and the vacuum partition to protect it. However, when in use, the oil tank is usually buried underground, with only the manhole exposed on the ground. It is inevitably subject to being run over by vehicles, which causes the manhole to exert downward pressure and squeeze the outer tank of the double-walled oil tank, easily damaging the outer tank. Utility Model Content

[0005] The main objective of this invention is to provide a double-walled oil tank with leak detection, which can effectively solve the technical problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A double-walled oil tank with leak detection includes an outer tank, a base fixedly installed at the bottom of the outer tank, an inner tank fixedly installed on the inner wall of the outer tank, an inert gas filling the space between the outer and inner tanks, two manholes on the top of the inner tank, a top cover on the top of the manholes, a sealing ring fixedly installed on the outer wall of the top cover, a connecting pipe on the inner wall of the inner tank, the outer wall of the connecting pipe penetrating both the outer and inner tanks, and a gas detector fixedly installed on the top of the connecting pipe.

[0008] As a further embodiment of this utility model, a support block is fixedly installed on the top of the outer tank, and a groove is formed on the outer wall of the support block.

[0009] As a further embodiment of this utility model, a spring is fixedly installed on the inner wall of the groove, and a support plate is fixedly installed on the top of the spring.

[0010] As a further embodiment of this utility model, a fixing plate is fixedly installed on the top of the support plate, and a water distribution groove is formed on the top of the fixing plate.

[0011] As a further embodiment of this utility model, two rotating blocks are fixedly installed on the top of the water distribution trough, and a well cover is rotatably connected to the adjacent surfaces of the two rotating blocks, and the well cover is adaptively matched with the outer wall of the water distribution trough.

[0012] As a further embodiment of this utility model, inclined blocks are fixedly installed on the left and right outer walls of the fixing plate, and the inclined blocks are located at the top of the support plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This double-walled oil tank with leak detection works as follows: When a car passes over the manhole cover, the manhole cover is subjected to force, which is transmitted to the fixed plate. During the downward pressure, the fixed plate drives the support plate to press down. As the support plate presses down, the spring at the bottom is compressed, thus buffering the entire structure. The support plate can also fit into the groove. After the car passes, when the spring is no longer under pressure, it will drive the support plate to rebound upward, restoring the entire structure to its initial position. The surface of the outer tank will not be damaged by the downward pressure from the passing car.

[0015] 2) This double-walled oil tank with leak detection will allow rainwater to fall onto the manhole cover during rainy weather. The water distribution channel will separate the rainwater and direct it elsewhere. Through the adaptive matching between the manhole cover and the outer wall of the water distribution channel, the manhole cover will not allow rainwater to flow into the manhole, thus preventing rainwater from seeping into the manhole.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] See Figure 1 and Figure 2 Furthermore, the inner tank 3 has two manholes 4 on its top, and a top cover 5 is provided on the top of the manholes 4. A sealing ring 6 is fixedly installed on the outer wall of the top cover 5. A connecting pipe 7 is provided on the inner wall of the inner tank 3. The outer wall of the connecting pipe 7 passes through both the outer tank 1 and the inner tank 3. A gas detector 8 is fixedly installed on the top of the connecting pipe 7. A support block 9 is fixedly installed on the top of the outer tank 1. A groove 10 is provided on the outer wall of the support block 9. A spring 11 is fixedly installed on the inner wall of the groove 10. A support plate 12 is fixedly installed on the top of the spring 11.

[0025] Specifically, the base 2 can fix the outer tank 1, the outer tank 1 can support the inner tank 3, the inert gas can insulate against heat and prevent negative pressure, the manhole 4 allows personnel to enter and clean the inner wall of the oil tank, the top cover 5 can plug the manhole 4 and the sealing ring 6 can seal it, the connecting pipe 7 can connect to the gas detector 8, the gas detector 8 can detect inert gas and issue an alarm, and the groove 10 can fix the spring 11.

[0026] Example 2

[0027] See Figure 3 and Figure 4Furthermore, based on Embodiment 1, a fixing plate 13 is fixedly installed on the top of the support plate 12, a water distribution channel 14 is opened on the top of the fixing plate 13, two rotating blocks 15 are fixedly installed on the top of the water distribution channel 14, a manhole cover 16 is rotatably connected to the adjacent surfaces of the two rotating blocks 15, and the manhole cover 16 is adaptively matched with the outer wall of the water distribution channel 14. Inclined blocks 17 are fixedly installed on the left and right outer walls of the fixing plate 13, and the inclined blocks 17 are located on the top of the support plate 12.

[0028] Specifically, the support plate 12 can fix the fixing plate 13, the water trough 14 can separate the falling rainwater, the rotating block 15 can rotate the manhole cover 16, and the manhole cover 16 will not allow rainwater to flow into the manhole 4 due to the adaptive matching between the manhole cover 16 and the outer wall of the water trough 14, and the inclined block 17 can facilitate the driving of vehicles.

[0029] In actual operation, when a car passes over the surface of the manhole cover 16, the manhole cover 16 is subjected to force and transmits the downward pressure to the fixing plate 13. During the downward pressing process, the fixing plate 13 drives the support plate 12 to press down. When the support plate 12 presses down, the spring 11 fixed at the bottom is compressed due to the elastic force, so that the whole is buffered. The support plate 12 can fit with the groove 10. After the car passes, when the spring 11 is no longer under pressure, it will drive the support plate 12 to rebound upward, and the whole returns to the initial position. When it rains, the falling rainwater will fall onto the manhole cover 16. The water diversion channel 14 can separate the falling rainwater and let it flow elsewhere. Through the adaptive matching between the manhole cover 16 and the outer wall of the water diversion channel 14, the manhole cover 16 will not allow rainwater to flow into the manhole 4.
