[0002] The oil pipeline is composed of oil pipes and their accessories, and is equipped with corresponding oil pump units according to the needs of the process flow, and is designed and installed into a complete pipeline system for completing the tasks of oil loading and unloading and transfer. Gas stations are places where oil pipelines are concentrated, but due to the coming and going of vehicles at gas stations, there is a certain risk of fire during the refueling process. If an accident occurs, the oil in the gas station is an extremely dangerous substance, and the existing oil pipelines themselves often do not have the ability to cut off the oil supply in an emergency. There is often a closing function at the end of the oil gun, but the oil gun itself is easily damaged in the event of an accident, and the method of closing the main gate is too slow to prevent the occurrence of accidents in time. In addition, the existing method of closing by rotating the valve is inefficient and often requires manual operation. In a chaotic situation, it is difficult to close in time.

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.

[0023] See also Figure 1-4 The utility model provides an embodiment: a gas station oil pipeline that can be cut off in an emergency, comprising an oil pipeline body 1, wherein the oil pipeline body 1 is connected to both ends of a mounting box 2;

[0024] Three groups of movable grooves 3 are provided in the installation box 2, shielding plates 4 are movably inserted in the movable grooves 3, a magnetic block 5 is fixedly installed on the upper end of the shielding plate 4, a mounting block 6 is movably provided on the upper end of the installation box 2, and magnetic rollers 7 are arranged in an array in the mounting block 6;

[0025] A sealing mechanism, which is disposed in the installation box 2 and is used to block the flow of oil in the installation box 2;

[0026] A replacement mechanism is arranged on the mounting block 6 and is used to replace the magnetic roller 7. The device can quickly close the oil pipeline body 1 through a closing mechanism, and is also provided with a replacement mechanism so that the magnetic roller 7 can be conveniently replaced;

[0027] Furthermore, the closing mechanism includes a pressing plate 8, which is fixedly mounted on the lower side of the shielding plate 4, a limit frame 9 is fixedly mounted on the upper side of the movable groove 3, a rubber pad 10 is fixedly mounted on the lower side of the limit frame 9, and the upper end of the pressing plate 8 abuts against the rubber pad 10, such as Figure 4 As shown, this structure enables the shielding plate 4 to be tightly against the limiting frame 9 when it is attracted and lifted, so that the shielding plate 4 has better sealing performance for the installation box 2 and increases the stability of the device when in use.

[0028] Furthermore, the magnetic block 5 is in an inverted trapezoidal shape, and the magnetic block 5 is tightly fitted with the upper end of the installation box 2 when attracted by the magnetic roller 7. Figure 4 As shown, this structure makes the upper end of the shielding plate 4 more sealed and has a better guiding effect when encountering oil.

[0029] Furthermore, the oil in the oil pipeline body 1 flows from the back to the front, and a pressure gauge 11 is provided on the front side of the oil pipeline body 1, and a valve 12 is provided on the rear side of the oil pipeline body 1. Figure 2 As shown, this structure allows the pressure in the oil pipeline body 1 to be observed, and further sealing can be performed through the valve 12 after the shielding plate 4 is closed.

[0030] Furthermore, the installation box 2 is fixedly mounted on the installation frame 13, and there is a clear gap between the installation box 2 and the lower side of the installation frame 13, such as Figure 1 As shown, this structure makes it difficult for the installation box 2 to be affected by ground moisture, etc., so that the use of the equipment can be more stable.

[0031] Furthermore, a cylinder 14 is installed at the center of the mounting frame 13, and the output shaft of the cylinder 14 is connected to the center of the mounting block 6. Guide rods 15 are fixedly installed on the left and right sides of the upper end of the mounting block 6, and the guide rods 15 move in the mounting frame 13, such as Figure 1 As shown, this structure allows the mounting block 6 to be driven by the cylinder 14 to move stably, so that the mounting block 6 can be automatically lifted, thereby increasing the convenience of using the device.

[0032] Furthermore, a rubber block 16 is fixedly mounted on the upper end of the guide rod 15, and a rubber ring is arranged on the outer side of the guide rod 15. Figure 3 As shown, this structure allows the guide rod 15 to be lifted by hand when the cylinder 14 is not working, and the rubber block 16 prevents the mounting block 6 from falling excessively.

[0033] Furthermore, the replacement mechanism includes an insertion groove 17, and the insertion groove 17 is arranged in an array on the mounting block 6. The edge of the insertion groove 17 is rounded, and the magnetic roller 7 is inserted in the insertion groove 17. The front end of the magnetic roller 7 is provided with a finger groove 18, such as Figure 2 As shown, this structure allows the magnetic roller 7 to be replaced and magnetized, thereby increasing the service life of the equipment.

[0034] Working principle: When an emergency occurs, the cylinder 14 starts to drive the mounting block 6 to descend and fit the upper side of the mounting box 2. At this time, the magnetic roller 7 attracts the magnetic block 5, and the magnetic block 5 rises and fits the upper side of the mounting box 2. At this time, the upper side of the pressing plate 8 is tightly fitted with the limit frame 9 and the rubber pad 10, completing the closure of the shielding plate 4 to the mounting box 2. At this time, the oil in the mounting box 2 is blocked, and the pressure in the oil pipeline body 1 can be observed through the pressure gauge 11 or the flow of oil in the oil pipeline body 1 can be completely closed through the valve 12. When the closure is completed, the telescopic rod of the cylinder 14 is retracted to drive the mounting block 6 to rise. At this time, the shielding plate 4 falls back under the action of gravity to end the closure. When replacing the magnetic roller 7, hold the finger groove 18 to pull it out and magnetize it or replace it. The above is the entire working principle of the utility model.
