[0046] See Figures 1-10 This is an embodiment of an oil tank for refueling proposed in this utility model. An oil tank 100 for refueling includes: a tank body 10 and a refueling box 20. The tank body 10 has a double-layer body 11 and a single-layer top plate 12. The double-layer body 11 has a double-layer bottom plate, two double-layer end plates and two double-layer side plates.

[0047] The refueling box 20 has a box body 21 fixed to the top plate 12 and a closable lid 22, the rear of which is hinged to the top plate 12. The lower part of the box body 21 is located inside the tank body 10, and the upper part of the box body 21 protrudes upward from the top plate 12. Multiple oil outlets 41 connected to oil pipes are provided inside the box body 21. When the lid 22 is closed, a passage 23 for the oil pipe to pass through is provided between the box body 21 and the lid 22; the lid 22 can be locked onto the top plate 12. The refueling box 20 is located on the top plate 11 of the tank body 10. The box body 21 has multiple oil outlets 23 connected to oil pipes, facilitating simultaneous refueling operations by connecting multiple oil outlets 41 to multiple oil pipes. Furthermore, with the lid 22 closed, the passage 23 for the oil pipes allows refueling without opening the lid 22, reducing operational steps. The lid 22 can be locked onto the top plate 12, which can prevent unauthorized opening and, to a certain extent, avoid the theft of oil when the oil tank 100 is placed in a remote outdoor area, thus enhancing the safety of oil storage and use.

[0048] In some embodiments of this application, the lid 22 has a cover plate 221 and a rear edge extending downward along the edge of the cover plate 221, as well as two side edges 222, i.e., no front edge. A front groove is provided at the upper end of the box body 21, and an opening 23 is formed between the front groove and the cover plate 221. The rear edge and the two side edges 222 can form a good sealing structure with the box body 21 when the lid 22 is closed, effectively preventing rainwater, dust and other external debris from entering the inside of the fuel box, protecting the fuel outlet and other components inside the box, ensuring their normal operation and extending their service life. At the same time, this partially open design allows the fuel outlet pipe to pass through while maintaining the relative sealing of the fuel box to the greatest extent, which helps to improve the overall protective performance.

[0049] In some embodiments of this application, the lid 22 is hinged to the top plate 12. A first locking hole 223 is provided at the front of the side edge 222. A locking plate 121 is provided on the top plate 12, which is parallel to the side edge 222. A second locking hole 1211 matching the first locking hole 223 is provided on the locking plate 121. The locking plate 121 is located outside the side edge 222. By passing a lock through the first locking hole 223 and the second locking hole 1211, the lid 22 can be locked.

[0050] In some embodiments of this application, the tank 10 is provided with a partition plate 13 for dividing the internal space. A flow port 131 is provided between the partition plate 13 and the inner wall of the tank 10 for liquid to flow between the two sides of the partition plate 13. A manhole 132 is provided on the partition plate 13 for personnel to enter at the rear edge.

[0051] In some embodiments of this application, the tank 10 has a double-layer body 11 and an interlayer gap cavity located between the double-layer body 11. The double-layer body 11 has a double-layer bottom plate, two double-layer end plates, and two double-layer side plates. The interlayer gap cavities at different locations are interconnected. To prevent excessive pressure in the interlayer gap cavity, a connecting pipe 30 is provided, and an emergency pressure relief valve 31 is provided at the end of the connecting pipe 30. When the pressure in the interlayer gap cavity reaches a set value, the gas pressure in the connecting pipe 30 can push the emergency pressure relief valve 31 to open, thereby releasing the pressure and ensuring the safety of the pressure in the interlayer gap cavity. The double-layer body 11 structure forms an interlayer gap cavity, which can prevent leakage of the tank 10 due to external factors to a certain extent. Even if the outer body is damaged, the inner body can still play a certain protective role, reducing the risk of oil leakage. At the same time, the emergency pressure relief valve 31 can release pressure in time when the pressure in the interlayer gap cavity is too high, avoiding deformation or even rupture of the tank 10 due to excessive pressure, further ensuring the safe operation of the oil tank and reducing the possibility of safety accidents. The interlayer gap cavity can play a certain role in heat insulation, reducing the impact of external ambient temperature on the oil in the tank, helping to maintain the stability of the oil, and preventing the oil from deteriorating or oxidizing due to excessively rapid or high temperature changes, thereby ensuring the quality of the oil.

[0052] In some embodiments of this application, the connecting pipe 30 is located inside the tank body 10, and an extension hole 212 for the upper end of the connecting pipe 30 is provided on the housing 21. The emergency release pressure valve 31 is located inside the housing 21. The connecting pipe 30 being located inside the tank body 10 ensures a relatively stable and safe environment, preventing damage from external factors such as collisions or scratches, thus guaranteeing a stable connection between the interlayer gap cavity and the emergency release pressure valve 31, thereby ensuring the normal operation of the pressure release system. The emergency release pressure valve 31 being located inside the housing 21 allows operators to directly open the housing cover for inspection, testing, and maintenance during routine checks and maintenance, without the need for additional tools or complex operating procedures, reducing maintenance costs and difficulty. The space of the tank body 10 and the refueling box 20 is fully utilized, making the entire tank structure more compact, reducing the equipment's footprint and space occupation, improving space utilization, and facilitating the use of mobile tanks in special areas with limited space.

[0053] In some embodiments of this application, the connecting pipe 30 is vertically arranged, and a connection port for connecting the lower end of the connecting pipe 30 is provided on the inner layer plate at the bottom of the tank body 10. An annular reinforcing fixing plate 32 is fitted onto the lower end of the connecting pipe 30, and the lower end of the reinforcing fixing plate 32 is sealed and fixed to the inner layer plate. The connecting pipe 30 not only stabilizes the pressure in the interlayer gap cavity but also supports the tank body 10. The sealing and fixing of the reinforcing fixing plate 32 to the inner layer plate helps improve the sealing performance of the connection, prevents gas or liquid in the interlayer gap cavity from leaking from the connection port, and increases the strength of the structure.

[0054] In some embodiments of this application, the emergency pressure release valve 31 has a valve body 311 and a valve cover 312 that can move up and down and is disposed on the upper end of the valve body 311. The valve cover 312 has a horizontally arranged valve cover plate 3121 and a valve cover edge 1322 that extends downward along the edge of the valve cover plate 3121. The design of the valve cover 312 that can move up and down allows adjustment of the distance between the valve cover 312 and the valve body 311, realizing automatic adjustment of the size of the air outlet. When the pressure in the interlayer gap cavity reaches a set value, the valve cover 312 can respond in time and move upward, and the gas is quickly discharged through the valve body, realizing efficient pressure release and ensuring that the pressure in the interlayer gap cavity is always within a safe range. The design of the valve cover edge 1322 increases the structural strength and stability of the valve cover 132, making it less prone to deformation or damage under frequent pressure changes and gas impacts.

[0055] In some embodiments of this application, a plurality of circumferentially arranged mounting rods 313 are provided between the valve body 311 and the valve cover 312, and a plurality of mounting blocks 314 are provided circumferentially on the valve body 311. Mounting holes for the mounting rods 313 to pass through are provided on the mounting blocks 314. The mounting rods 313 passing through the mounting holes on the mounting blocks 314 provide precise guidance for the up-and-down movement of the valve cover 312, ensuring that the valve cover 312 can only move vertically along the direction of the mounting rods 313, preventing the valve cover 312 from shifting or wobbling during movement. This ensures that the valve cover 312 can accurately cover the valve body 311, achieving a good sealing effect, and can stably open and close during pressure release. The circumferential distribution of the mounting rods 313 and mounting blocks 314 connects the valve cover 312 and the valve body 311 at multiple points, making the connection between the two more stable.

[0056] In some embodiments of this application, a nut 315 is provided at the lower end of the mounting rod 313, and a spring 316 is provided between the nut 315 and the mounting block 314, with the spring 316 sleeved on the mounting rod 313. When the pressure in the interlayer gap cavity reaches a set value, the gas pressure overcomes the elastic force of the spring 316 to push the valve cover 312 upward, thereby releasing the pressure. When the pressure decreases, the spring 316 can reset the valve cover 312, ensuring the normal closure of the valve cover 312 and playing a role in automatically regulating and controlling the pressure. During the opening and closing of the valve cover 312, the spring 316 can buffer the impact force of the gas pressure on the valve cover 312 and the valve body 311, reducing wear and collision between components, reducing the risk of component damage due to impact, thereby extending the service life of the emergency release pressure valve and improving its operational stability and reliability. By adjusting the position of the nut 315 on the mounting rod 313, the preload of the spring 316 can be changed, thereby adjusting the opening pressure setting value of the emergency release pressure valve 31. This adjustability allows the device to be flexibly set with appropriate pressure release values ​​according to different usage requirements and operating conditions, thus improving the device's applicability and versatility.

[0057] In some embodiments of this application, the tank body 31 is provided with an inner oil pipe 40 that is connected to the oil outlet 41 and extends downward, and the lower end of the inner oil pipe 40 is spaced apart from the bottom of the tank body 10.

[0058] In some embodiments of this application, a vent 122 is provided on the top plate 12 for connection to the vent pipe 50, and a removable plug is provided at the vent 122. The vent pipe 50 has multiple detachably connected pipe segments 51, and a fixing bracket 60 is provided on the top plate 12 for fixing the multiple pipe segments 51 during transportation. The vent pipe 122 is composed of multiple detachably connected pipe segments 51. During transportation, the pipe segments 51 can be disassembled and fixed using the fixing bracket 60 on the top plate 12. This reduces the transportation volume and facilitates the transportation of the oil tank 100 to remote mountainous areas, mining areas, disaster areas, and other special areas, reducing transportation difficulty and cost. After arriving at the destination, the pipe segments 51 of the vent pipe can be easily assembled and connected to the vent 122 on the top plate 12. The installation process is simple and quick. In use, the vent pipe 50 can stabilize the air pressure in the oil tank by connecting the air inside and outside the oil tank, maintaining the air pressure balance inside and outside the oil tank, and avoiding safety problems such as oil inlet / outlet failures caused by abnormal oil tank pressure. A removable plug is provided at the vent 122. When the vent pipe 50 is not needed, it can be blocked to prevent debris from entering the tank. When it is needed, it can be opened again. The use of the vent pipe can be flexibly selected according to the actual situation, which improves the flexibility of the oil tank container.
