[0001] The utility model relates to the technical field of oil storage, in particular to a storage tank used for oil transportation. Background Art

[0002] Petroleum is one of the main objects of geological exploration. It is a viscous, dark brown liquid, known as the "blood of industry". Petroleum is stored in some areas of the upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. Petroleum is mainly used as fuel and gasoline. It is also the raw material for many chemical industrial products, such as solutions, fertilizers, pesticides, and plastics. Storage tanks are required during the transportation of petroleum. The existing storage tanks have a relatively simple structure. Due to the hot weather, the crude oil inside the storage tank is very easy to evaporate, resulting in an increase in the internal pressure of the tank, which can easily cause the tank to explode.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, a storage tank for oil transportation includes a tank body 1, a liquid inlet pipe 3 is arranged in the middle of the upper side of the tank body 1, a liquid discharge pipe 4 is arranged at the lower part of the tank body 1, solenoid valves are installed in the middle of the liquid inlet pipe 3 and the liquid discharge pipe 4, a hydraulic mechanism 5 is arranged on one side of the upper part of the tank body 1, and a cooling mechanism 2 is arranged at the bottom of the tank body 1.

[0021] In this embodiment, the hydraulic mechanism 5 includes a sleeve 501, a bracket 502, a sealing seat 503, a sealing ring 504, a spring 505, a connecting rod 506 and a limit plate 507. The lower part of the sleeve 501 is fixedly connected to one side of the upper part of the tank body 1, the outer periphery of the bracket 502 and the sealing ring 504 are installed in the lower middle part of the tank body 1, the sealing ring 504 is arranged on the upper part of the bracket 502, the outer periphery of the connecting rod 506 is slidably connected to the middle part of the bracket 502, the middle part of the sealing seat 503 is arranged on the upper end of the connecting rod 506, the sealing seat 503 is arranged on the upper part of the sealing ring 504, the middle part of the limit plate 507 is fixedly connected to the lower part of the connecting rod 506, the spring 505 is fixedly connected to the lower part of the connecting rod 506, and the sealing seat 503 is arranged on the upper part of the sealing ring 504. 505 is sleeved on the outer periphery of the lower part of the connecting rod 506, the spring 1 505 is arranged between the bracket 1 502 and the limit plate 507, the hydraulic mechanism 5 also includes a spring 2 508, a limit cover 509, a bracket 2 510, a threaded rod 511 and a knob 512, the outer periphery of the bracket 2 510 is fixedly connected to the upper part of the sleeve 501, the outer periphery of the threaded rod 511 is threadedly connected to the middle part of the bracket 2 510, the middle part of the knob 512 is fixedly connected to the upper part of the threaded rod 511, the middle part of the limit cover 509 is fixedly connected to the lower end of the threaded rod 511, the spring 2 508 is arranged between the sealing seat 503 and the limit cover 509, and a plurality of partitions 6 are arranged on the inner top wall of the tank body 1.

[0022] Specifically, when the internal pressure of the tank body 1 increases, the gas will push the sealing seat 503, so that the sealing seat 503 drives the limit plate 507 to move upward through the connecting rod 506 and overcome the elastic force of the spring 1 505, so that the gas inside the tank body 1 is discharged, thereby reducing the pressure inside the tank body 1. When the pressure of the tank body 1 is lower than the elastic force of the spring 1 505 and the spring 2 508, the sealing seat 503 will reset under the action of the spring 1 505 and the spring 2 508, so that the sealing seat 503 blocks the sealing ring 504, effectively preventing the tank body 1 from bursting due to excessive pressure inside the tank body 1. By turning the knob 512, the threaded rod 511 drives the limit cover 509 to move up and down, so that the pressure of the spring 2 508 changes, so that the pressure required for pressure relief is adjusted according to demand.

[0023] In this embodiment, the cooling mechanism 2 includes a bottom tank 201, a water pump 202, a circulation pipe 203, a cavity 204, a sealing cover 205 and a water supply pipe 206. The bottom tank 201 is installed at the lower part of the tank body 1. Ice water is arranged inside the tank body 1. The water pump 202 is installed on the bottom wall of the bottom tank 201. The circulation pipe 203 is arranged inside the cavity 204. The cavity 204 is opened on the side wall of the tank body 1. One end of the circulation pipe 203 passes through the bottom tank 201 and is fixedly connected to the water pump 20 2, the other end of the circulation pipe 203 passes through the upper part of the bottom tank 201, the lower end of the water supply pipe 206 is fixedly connected to the upper part of the bottom tank 201, the outer periphery of the sealing cover 205 is arranged on the upper part of the sealing cover 205, the cooling mechanism 2 also includes a water inlet pipe 207 and a filter 208, the middle part of the filter 208 is installed at one end of the water inlet pipe 207, the other end of the water inlet pipe 207 is fixedly connected to the input end of the water pump 202, and the outer periphery of the tank body 1 and the bottom tank 201 is provided with a heat preservation cover.

[0024] Specifically, the ice water in the bottom tank 201 circulates between the circulation pipe 203 and the bottom tank 201 through the water pump 202, and the oil in the tank body 1 is cooled by the low temperature of the ice water, thereby reducing the evaporation rate of the oil and preventing the internal pressure of the tank body 1 from being too high, causing the tank body 1 to burst.

[0025] Working principle:

[0026] When the pressure inside the tank body 1 increases, the gas will push the sealing seat 503, so that the sealing seat 503 drives the limit plate 507 to move upward through the connecting rod 506 and overcome the elastic force of the spring 1 505, so that the gas inside the tank body 1 is discharged, thereby reducing the pressure inside the tank body 1. When the pressure of the tank body 1 is lower than the elastic force of the spring 1 505 and the spring 2 508, the sealing seat 503 will reset under the action of the spring 1 505 and the spring 2 508, so that the sealing seat 503 blocks the sealing ring 504, effectively preventing the tank body 1 from leaking. The excessive internal pressure may cause the tank body 1 to burst. By turning the knob 512, the threaded rod 511 drives the limit cover 509 to move up and down, thereby changing the pressure of the spring 2 508, thereby adjusting the pressure required for pressure relief according to demand. Through the water pump 202, the ice water inside the bottom tank 201 circulates between the circulation pipe 203 and the bottom tank 201. The low temperature of the ice water cools the oil inside the tank body 1, reduces the evaporation rate of the oil, and prevents the internal pressure of the tank body 1 from being too high, causing the tank body 1 to burst.
