Description

Technical Field

[0001] This utility model relates to the field of gasoline storage tank technology, and more specifically to a safe gasoline storage device with high sealing performance. Background Technology

[0002] Oil storage tanks are containers for storing oil products. They are the main equipment in oil depots. Oil storage tanks can be classified according to their material into metal tanks and non-metal tanks; according to their location into underground tanks, semi-underground tanks, and above-ground tanks; according to their installation method into vertical and horizontal tanks; and according to their shape into cylindrical, box-shaped, and spherical tanks.

[0003] When using oil storage tanks to store gasoline, due to the volatile, flammable, and explosive properties of gasoline, if the tank is not well sealed, the gasoline vapors produced by evaporation can mix with air and, when they reach a certain concentration, easily cause explosions and fires when exposed to open flames, static electricity, or high temperatures. This poses a significant threat to human life and property. An unsealed environment can also lead to gasoline contamination from the outside, affecting its quality. Therefore, improving the sealing and safety of oil storage tanks is crucial.

[0004] This utility model provides a highly sealed and safe gasoline storage device, which was developed to solve these problems, reduce the temperature and pressure inside the tank, and prevent explosion accidents. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a highly sealed and safe gasoline storage device to solve the problems existing in the background art.

[0006] This utility model provides the following technical solution: a highly sealed and safe gasoline storage device, including a storage tank, an oil outlet pipe is embedded in the lower right side of the storage tank, an oil inlet pipe is embedded in the top of the storage tank, a sealing valve is provided on the surface of the storage tank and the oil inlet pipe, and a pressure control component is provided inside the storage tank.

[0007] The pressure control assembly includes a buffer cylinder embedded in the top of the oil storage tank. The inner wall of the buffer cylinder has a buffer cavity. A piston plate is slidably connected to the inner wall of the buffer cavity. The piston plate is made of corrosion-resistant and insulating material. A support rod is fixedly installed on the top of the piston plate. An explosion-proof contact switch is installed at the top of the inner wall of the buffer cylinder. The support rod corresponds to the sensing end of the explosion-proof contact switch. A blind pipe is embedded at a high point on the side wall of the oil storage tank. The blind pipe extends to a high point inside the oil storage tank. An explosion-proof box is fixedly installed on the side wall of the oil storage tank. An explosion-proof refrigeration unit is fixedly installed on the inner wall of the explosion-proof box. The refrigeration circulation pipe of the explosion-proof refrigeration unit extends into the interior of the blind pipe. The explosion-proof contact switch is connected to the explosion-proof refrigeration unit.

[0008] Furthermore, a support spring is provided on the inner top wall of the buffer cylinder, and the bottom end of the support spring is fixed to the top of the piston plate.

[0009] As a further description of the above technical solution: by setting a support spring, the support spring can maintain its stable position when the piston plate is not subjected to abnormal pressure, ensuring the accurate operation of the pressure control component. At the same time, after the pressure returns to normal, the support spring can push the piston plate to reset, so that the device can quickly return to the initial safe state.

[0010] Furthermore, the bottom of the oil storage tank is fixedly equipped with support legs, and both the support legs and the outer wall of the oil storage tank are grounded through grounding wires.

[0011] As a further description of the above technical solution: the installation of outriggers and grounding wires not only provides stable support for the oil storage tank and prevents it from tipping over due to external forces, but more importantly, the grounding treatment can effectively conduct away the charge generated by friction, static electricity and other reasons in the oil storage tank, avoid the accumulation of charge and the generation of sparks, thereby eliminating the risk of explosion caused by static electricity.

[0012] Furthermore, the outer wall of the oil storage tank is covered with an insulation layer.

[0013] As a further description of the above technical solution: the insulation layer can reduce the heat exchange between the oil storage tank and the external environment. Especially in the high-temperature season, it can effectively block the external heat from entering the tank, maintain the relative stability of the tank temperature, further reduce the evaporation rate of gasoline, and improve the safety of storage.

[0014] Furthermore, the outer wall of the blind tube is welded with several heat-conducting copper wires, which are evenly distributed in a circumferential array on the surface of the blind tube.

[0015] As a further description of the above technical solution: the setting of heat-conducting copper wire enhances the heat conduction efficiency of the blind tube, so that the cooling capacity generated by the explosion-proof refrigeration unit can be distributed more quickly and evenly inside the oil storage tank, improving the cooling effect and also improving the overall energy efficiency of the device.

[0016] Furthermore, explosion-proof gas sensors are installed at the inlet and outlet of the oil pipe, and the explosion-proof gas sensors are connected to an external alarm signal.

[0017] As a further description of the above technical solution: the installation of the explosion-proof gas sensor can monitor the concentration of oil and gas in real time at the oil inlet and outlet pipes. Once the concentration of oil and gas exceeds the standard, it will immediately send a signal to the external alarm to remind the staff to take timely measures to prevent safety accidents caused by oil and gas leaks, thus adding a safety barrier to the storage process.

[0018] The technical effects and advantages of this utility model are as follows:

[0019] 1. Compared with existing technologies, this highly sealed and safe gasoline storage device, through the installation of a pressure control component, allows the piston plate to move upward against the elastic force of the support spring when the internal pressure of the storage tank increases due to factors such as gasoline evaporation. When the support rod touches the sensing end of the explosion-proof contact switch, the explosion-proof contact switch immediately sends a signal to the explosion-proof refrigeration unit, which then starts. Its refrigeration circulation pipe rapidly cools the inside of the storage tank through a blind pipe, reducing the evaporation rate of gasoline and promoting gasoline liquefaction, thereby reducing the pressure inside the tank. This effectively avoids the risk of explosion caused by excessive pressure and greatly improves the safety of the storage device.

[0020] 2. Compared with the prior art, this highly sealed and safe gasoline storage device, by setting a support spring, can maintain the piston plate in a stable position when it is not subjected to abnormal pressure, ensuring the precise operation of the pressure control components. At the same time, after the pressure returns to normal, the support spring can push the piston plate to reset, so that the device can quickly return to the initial safe state.

[0021] 3. Compared with existing technologies, this highly sealed and safe gasoline storage device not only provides stable support for the oil tank by setting up support legs and grounding wires to prevent it from tipping over due to external forces, but more importantly, the grounding treatment can effectively conduct away the charge generated by friction, static electricity and other reasons in the oil tank, avoid the accumulation of charge and the generation of sparks, thereby eliminating the risk of explosion caused by static electricity.

[0022] 4. Compared with existing technologies, this highly sealed and safe gasoline storage device reduces heat exchange between the storage tank and the external environment through the insulation layer. Especially in high-temperature seasons, it can effectively block external heat from entering the tank, maintain a relatively stable internal temperature, further reduce the evaporation rate of gasoline, and improve storage safety.

[0023] 5. Compared with existing technologies, this highly sealed and safe gasoline storage device enhances the heat conduction efficiency of the blind tube by incorporating heat-conducting copper wires. This allows the cooling capacity generated by the explosion-proof refrigeration unit to be distributed more quickly and evenly inside the oil tank, improving the cooling effect and enhancing the overall energy efficiency of the device.

[0024] 6. Compared with existing technologies, this highly sealed and safe gasoline storage device features an explosion-proof gas sensor that can monitor the concentration of gasoline vapors in real time at the inlet and outlet pipes. Once the concentration of gasoline vapors exceeds the standard, it immediately sends a signal to an external alarm, reminding staff to take timely measures to prevent safety accidents caused by gasoline vapor leaks, thus adding a safety barrier to the storage process.

[0029] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The highly sealed and safe gasoline storage device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0030] Reference Figures 1 to 3 This utility model provides a highly sealed and safe gasoline storage device, including a storage tank 1, an oil outlet pipe 2 embedded in the lower right side of the storage tank 1, an oil inlet pipe 3 embedded in the top of the storage tank 1, and sealing valves provided on the surfaces of the storage tank 1 and the oil inlet pipe 3.

[0031] The bottom of the oil storage tank 1 is fixedly equipped with a support leg 13, and the support leg 13 and the outer wall of the oil storage tank 1 are grounded through a grounding wire 14.

[0032] This highly sealed and safe gasoline storage device uses a storage tank 1 to store gasoline. The support legs 13 and grounding wire 14 not only provide stable support for the storage tank 1 and prevent it from tipping over due to external forces, but more importantly, the grounding treatment can effectively conduct away the charge generated by friction, static electricity and other reasons in the storage tank 1, avoid the accumulation of charge and the generation of sparks, thereby eliminating the risk of explosion caused by static electricity.

[0033] The outer wall of oil storage tank 1 is covered with an insulation layer 15.

[0034] The insulation layer 15 can reduce the heat exchange between the oil storage tank 1 and the external environment. Especially in the high-temperature season, it can effectively block the external heat from entering the tank, maintain the relative stability of the temperature inside the tank, further reduce the evaporation rate of gasoline, and improve the safety of storage.

[0035] The oil storage tank 1 is equipped with a pressure control component.

[0036] The pressure control assembly includes a buffer cylinder 4 embedded in the top of the oil storage tank 1. The inner wall of the buffer cylinder 4 has a buffer cavity 5. A piston plate 6 is slidably connected to the inner wall of the buffer cavity 5. The piston plate 6 is made of corrosion-resistant and insulating material. A support rod 7 is fixedly installed on the top of the piston plate 6. An explosion-proof contact switch 8 is installed at the top of the inner wall of the buffer cylinder 4. The position of the sensing end of the support rod 7 corresponds to that of the explosion-proof contact switch 8. A blind pipe 9 is embedded at a high point on the side wall of the oil storage tank 1. The blind pipe 9 extends to a high point inside the oil storage tank 1. An explosion-proof box 10 is fixedly installed on the side wall of the oil storage tank 1. An explosion-proof refrigeration unit 11 is fixedly installed on the inner wall of the explosion-proof box 10. The refrigeration circulation pipe of the explosion-proof refrigeration unit 11 extends into the interior of the blind pipe 9. The explosion-proof contact switch 8 is signal-connected to the explosion-proof refrigeration unit 11.

[0037] This highly sealed and safe gasoline storage device, through the installation of a pressure control component, causes the piston plate 6 to move upward under pressure when the internal pressure of the storage tank 1 increases due to factors such as gasoline evaporation. When the support rod 7 touches the sensing end of the explosion-proof contact switch 8, the explosion-proof contact switch 8 immediately sends a signal to the explosion-proof refrigeration unit 11, which then starts. Its refrigeration circulation pipe rapidly cools the inside of the storage tank 1 through the blind pipe 9, reducing the evaporation rate of gasoline and promoting gasoline liquefaction, thereby reducing the pressure inside the tank. This effectively avoids the risk of explosion caused by excessive pressure and greatly improves the safety of the storage device.

[0038] A support spring 12 is provided on the inner top wall of the buffer cylinder 4, and the bottom end of the support spring 12 is fixed to the top of the piston plate 6.

[0039] By setting the support spring 12, the support spring 12 can maintain its stable position when the piston plate 6 is not subjected to abnormal pressure, ensuring the accurate operation of the pressure control component. At the same time, after the pressure returns to normal, the support spring 12 can push the piston plate 6 to reset, so that the device can quickly return to the initial safe state.

[0040] Several heat-conducting copper wires 16 are welded to the outer wall of the blind tube 9, and the heat-conducting copper wires 16 are evenly distributed in a circumferential array on the surface of the blind tube 9.

[0041] Furthermore, the installation of the heat-conducting copper wire 16 enhances the heat conduction efficiency of the blind tube 9, enabling the cooling capacity generated by the explosion-proof refrigeration unit 11 to be distributed more quickly and evenly inside the oil storage tank 1, improving the cooling effect and also enhancing the overall energy efficiency of the device.

[0042] An explosion-proof gas sensor 17 is installed at the inlet of oil pipe 3 and the outlet of oil pipe 2. The explosion-proof gas sensor 17 is connected to the external alarm signal.

[0043] It is worth noting that the installation of the explosion-proof gas sensor 17 can monitor the concentration of oil and gas in real time at the oil inlet pipe 3 and the oil outlet pipe 2. Once the concentration of oil and gas exceeds the standard, it will immediately send a signal to the external alarm to remind the staff to take timely measures to prevent safety accidents caused by oil and gas leakage, thus adding a safety barrier to the storage process.

[0044] Finally, it should be noted that the accompanying drawings of the embodiments disclosed in this utility model only involve the structures involved in the embodiments disclosed in this utility model. Other structures can refer to the general design. In the absence of conflict, the same embodiment and different embodiments of this utility model can be combined with each other.
