[0002] Oil, also known as petroleum, crude oil or black gold, is a viscous dark brown liquid. Oil is stored in some areas of the upper crust of the earth.

[0003] At present, when storing and transporting oil products, the staff stores the oil products in double-layer tanks, and then moves the double-layer tanks to transport vehicles for transportation. Since the oil products inside the double-layer tanks are not full, when there are bumps, collisions or braking during transportation, the oil products inside will have different degrees of impact on the double-layer tanks. During the mutual friction process, the state of the oil products is extremely unstable. After the oil products are stored and transported to the designated location, if there is too much gas inside the double-layer tank, causing the pressure to exceed the preset safety limit, the gas inside the double-layer tank needs to be discharged through the exhaust pipe. If it is discharged directly, it will not only affect the air quality, but also easily cause adverse effects on the surrounding environment and residents' health.

[0004] In view of the above problems, it is necessary to design a safe storage and transportation device for oil products that filters the exhausted gas. Utility Model Content

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] Embodiment: A device for safe storage and transportation of oil products, such as Figure 1-Figure 4As shown, it includes a double-layer tank body 1, a leak detector 2, a baffle valve 3, an anti-overflow ball float 4, a floating sensor 5, a brine pressure sensor 6, a vent pipe 7, a one-way valve 8, an air filter 9, an oil outlet pipe 10, a valve 11, a guide rod 12, a mounting plate 13, an elastic member 14 and a partition 15. The double-layer tank body 1 is made of corrosion-resistant glass fiber. The leak detector 2 is installed on the left side of the double-layer tank body 1. The leak detector 2 detects the change of hydrogen concentration in the interlayer through its own sensor. Once the gas concentration exceeds the set threshold, it indicates that a leak has occurred. The leak detector The instrument 2 penetrates the double-layer tank body 1, and a baffle valve 3 is installed on the double-layer tank body 1. The baffle valve 3 penetrates the double-layer tank body 1. If the oil reaches the storage capacity inside the double-layer tank body 1, the baffle valve 3 can automatically cut off the source of the supplementary oil. The double-layer tank body 1 is equipped with an anti-overflow ball float 4. The anti-overflow ball float 4 penetrates the double-layer tank body 1. When the supplementary oil reaches the storage capacity inside the double-layer tank body 1, the float in the anti-overflow ball float 4 floats upward using the pressure of the steam in the double-layer tank body 1. When the float floats to a specified position, it can prevent additional oil from entering. Floating sensor 5, floating sensor 5 penetrates the double-layer tank body 1, when the oil value reaches a predetermined level, floating sensor 5 can sound an alarm, a salt water pressure sensor 6 is installed on the right side of the double-layer tank body 1, the salt water pressure sensor 6 penetrates the double-layer tank body 1, and is used to detect whether the liquid in the interlayer is lost, a venting pipe 7 is connected to the double-layer tank body 1, a one-way valve 8 is installed at the other end of the venting pipe 7, an air filter 9 is installed on the right side of the one-way valve 8, an oil outlet pipe 10 is connected to the bottom of the double-layer tank body 1, and a valve 11 is installed on the oil outlet pipe 10, the double-layer tank The lower part of the body 1 is symmetrically connected with guide rods 12 at the front and back, and the double-layer tank body 1 is slidably connected to the guide rods 12. The guide rods 12 are Π-shaped, and the guide rods 12 play a guiding role. A mounting plate 13 is connected between the bottoms of the four guide rods 12, and the number of the mounting plates 13 is not less than two. An elastic member 14 is connected between the upper side of the mounting plate 13 and the lower part of the double-layer tank body 1. When the double-layer tank body 1 is placed, it is used to buffer the double-layer tank body 1. A plurality of partitions 15 are evenly spaced and connected inside the double-layer tank body 1, which can reduce the impact force of the oil when the oil shakes.

[0020] When the device needs to be transported, the staff uses a crane to carry the device to the transport vehicle. After the device is placed, during the placement of the device, because the device is heavy and oil is stored inside, under the action of gravity, the device moves downward along the guide rod 12, and the elastic member 14 is compressed, which can play a buffering role for the device. During transportation, if a bumpy road section is encountered, the transport vehicle will shake violently, causing the oil in the double-layer tank body 1 to shake due to the bumps of the transport vehicle, and an impact force is generated under the shaking of the oil. The shaking of the oil will contact and impact the partition 15. Because a plurality of partitions 15 are installed inside the double-layer tank body 1, the interior of the double-layer tank body 1 is divided into a plurality of smaller spaces, which can significantly reduce the amplitude of the oil shaking, thereby reducing the oil The impact force of the oil is reduced, and the partition 15 can also reduce the noise caused by the shaking of the oil. When there is too much gas in the double-layer tank body 1, causing the pressure to exceed the preset safety limit, the pressure relief valve in the vent pipe 7 is activated, so that the gas in the double-layer tank body 1 flows into the vent pipe 7, and then flows from the vent pipe 7 to the one-way valve 8, and then flows from the one-way valve 8 to the air filter 9. The air filter 9 filters the gas to prevent pollution to the surrounding environment and prevent overpressure in the double-layer tank body 1. When the internal pressure of the double-layer tank body 1 drops to the preset safety threshold, the pressure relief valve in the vent pipe 7 is closed. After the device is transported to the gas station, the staff uses a crane to place the device flat on the ground. When it is necessary to detect the leakage of the double-layer tank body 1, Since the leak detector 2 remains open, and a mixed gas of a specific ratio (such as 5% hydrogen + 95% nitrogen) is injected into the interlayer of the double-layer tank body 1, and since hydrogen has extremely high diffusivity and is easily detectable, when the inner tank leaks, hydrogen will leak into the interlayer. The leak detector 2 detects changes in the hydrogen concentration in the interlayer through its own sensor. Once the gas concentration exceeds the set threshold, indicating that a leak has occurred, the sensor on the leak detector 2 will sound an alarm to alert the staff. At the same time, a closed liquid circulation loop is set in the interlayer of the double-layer tank, which may contain brine or other suitable liquid media, and the brine pressure sensor 6 is installed in the closed liquid circulation loop. Since the brine pressure sensor 6 remains open, the pressure sensor 6 is kept closed. In the open state, if the inner tank leaks, it may cause the loss of liquid in the interlayer, resulting in a reduction in the total volume in the circulation system, which in turn causes a drop in the liquid circulation pressure. The brine pressure sensor 6 detects that the pressure is lower than the preset safety threshold, and the system will trigger an alarm to remind the staff that there may be a leak inside the double-layer tank body 1, which needs further inspection and treatment. When it is necessary to replenish the underground double-layer tank body 1 with oil, during the process of replenishing the oil, if the oil reaches the storage capacity inside the double-layer tank body 1, the flapper valve 3 remains in the open state, so that the flapper valve 3 can automatically cut off the source of the replenished oil. At the same time, since the initial state of the anti-overflow ball float 4 is the open state, the oil is allowed to flow in freely. When the replenished oil reaches the storage capacity inside the double-layer tank body 1,The floating ball in the anti-overflow ball float 4 floats upward by using the steam pressure of the double-layer tank 1. When the floating ball floats to a certain position, it can prevent additional oil from entering. While the oil is being replenished, when the oil value reaches a predetermined level, the floating sensor 5 remains open, so that the floating sensor 5 will sound an alarm, thereby reminding the staff to close the delivery pipe.
