1 to 7, the seismic fuel tank 10 according to an embodiment of the tank body 100, the fuel transmission member 200, the first valve member 300, the second valve member 400, It may include a flow rate measuring member 500, the fuel return member 600, the overflow member 700, the exhaust member 800 and the flow rate display member 900.

The tank body 100 may be provided to receive fuel therein.

At this time, the tank body 100 is fluidly connected to the engine of the generator, it is possible to supply the fuel contained in the tank body 100 to the engine of the generator.

In addition, the tank body 100 may be designed to withstand the vacuum and positive pressure generated when fuel is injected or discharged.

For example, when excessive negative pressure is generated in the tank body 100, the tank body 100 may explode on its own, so the gas in the tank body 100 is properly exhausted to maintain the pressure in the tank body 100 at an appropriate level. Need to do.

Specifically, the tank body 100 may be provided with a fuel discharge port 110, a fuel injection port 120, a ventilation port 130, a check port 140 and a drain port 150.

The fuel discharge port 110 may be provided such that fuel is discharged toward the fuel inlet port A provided in the engine of the generator in the tank body 100.

For example, the fuel discharge port 110 may be provided with a fuel discharge port 110 on the upper surface of the tank body 100 so as to be disposed above the fuel inlet port A provided in the engine of the generator. In other words, the fuel inlet port A provided in the engine of the generator may be disposed below the fuel outlet port 110.

Thereby, the fuel discharged from the fuel discharge port 110 may be moved in the direction of gravity to be delivered to the fuel inlet port A provided in the engine of the generator.

Specifically, the fuel discharge port 110 may be connected to one side of the first valve member 300, which will be described in detail below.

The fuel injection port 120 is a port for filling the fuel in the tank body 100, for example, may be spaced from the fuel discharge port 110 on the top surface of the tank body 100.

In particular, with reference to FIG. 5 (a), when the fuel is not filled in the tank body 100 or when fuel is supplied to the engine of the generator (or when the engine is running), the end cap of the fuel injection port 120 is capped. 122 may be mounted. On the other hand, the cap 122 may be detached from the end of the fuel injection port 120 when filling the tank body 100 with fuel or when the engine of the generator is not supplied with fuel (or when the engine is not operated). .

The ventilation hole 130 is for communicating the outside air with the tank body 100, for example, may be disposed on one side from the top surface of the tank body 100.

Specifically, the gas in the tank body 100 expands as the internal temperature of the tank body 100 rises due to exposure to direct sunlight for a long time, the external temperature rise, or the engine running circulating fuel. Therefore, an abnormal high pressure may be formed, which may cause an explosion. Alternatively, as fuel is consumed by the operation of the engine, negative pressure may be generated in the tank body 100 to interfere with the function of the fuel pump.

At this time, the gas of the tank body 100 is discharged to the outside air through the vent 130 and the outside air is introduced into the tank body 100, thereby solving the above-described problem.

In particular, referring to Figure 5 (b), the end of the vent 130 may be formed to be curved. At this time, a flammable Arrester (combustion gas arrester) is installed in the vent 130 to prevent ignition due to combustion gas.

The inspection hole 140 is for maintenance in the tank body 100, for example, it may be disposed centrally on the top surface of the tank body 100.

At this time, maintenance can be performed in the tank body 100 by opening the inspection hole 140.

The drain port 150 is for removing sediment and condensate that are settled in the tank body 100, and may be disposed on the lower surface of the tank body 100, for example.

At this time, sediment and condensate precipitated in the tank body 100 by the drain port 150 may be periodically removed.

The fuel transmission member 200 may be disposed in the tank body 100 described above.

The fuel delivery member 200 may transfer fuel accommodated in the tank body 100 to the fuel discharge port 110 provided on the top of the tank body 100.

Specifically, the fuel transmission member 200 is provided in a tubular shape, and may be formed to extend toward the bottom from the top of the tank body 100.

For example, the fuel delivery member 200 may be provided as a drop tube.

At this time, the upper end of the fuel transmission member 200 protrudes to the outside through the upper surface of the tank body 100, and the lower end of the fuel transmission member 200 may be located adjacent to the lower surface of the tank body 100.

Accordingly, the lower end of the fuel transmission member 200 may be kept locked in the fuel accommodated in the tank body 100, and when the fuel is supplied to the engine, the fuel received in the tank body 100 is the fuel delivery member 200. The fuel may be delivered toward the upper end of the fuel delivery member 200 through the lower end to be delivered to the fuel discharge port 110.

In particular, since the drop tube remains submerged in the fuel within the tank body 100, it is possible to increase the fuel transfer flow rate and reduce ignition fumes, bubbles and potential fuel evaporation from the tank body 100.

At this time, the ignition ignition is a gas that can be ignited and exploded when the fuel goes from a liquid state to a vaporization state, and can cause a fire when the ignition is not discharged to the outside.

A first valve member 300 may be mounted on an upper end of the fuel transmission member 200.

The first valve member 300 is for preventing the capillary phenomenon of the tank body 100, and can prevent the tendency of the fuel accommodated in the tank body 100 to flow from a high place to a low place by a capillary phenomenon. .

For example, when a problem occurs in the supply line S for transferring the fuel accommodated in the tank body 100 to the fuel inlet port A provided in the engine, the fuel accommodated in the tank body 100 due to the capillary phenomenon All can leak.

In particular, in the event of an earthquake, a problem may occur in the supply line S that transfers the fuel accommodated in the tank body 100 to the fuel inlet port A provided in the engine, to close the first valve member 300. In this case, the upper end of the fuel transmission member 200 is closed, so that fuel contained in the tank body 100 can be prevented from leaking.

Specifically, when supplying fuel to the engine, the first valve member 300 is opened to transfer the fuel contained in the tank body 100 to the fuel inlet port A provided in the engine of the generator through the supply line S. Can be. On the other hand, when the fuel is not supplied to the engine, the first valve member 300 is closed to prevent the fuel contained in the tank body 100 from being discharged from the fuel discharge port 110.

Therefore, the first valve member 300 may be controlled to open when the fuel is supplied to the engine, and closed when the fuel is not supplied to the engine.

For example, the first valve member 300 may be provided as an anti-syphon valve, but the configuration of the first valve member 300 is not limited to this, and when the engine is supplied with fuel The fuel contained in the tank body 100 is discharged from the fuel discharge port 110, and when the fuel is not supplied to the engine, fuel contained in the tank body 100 is prevented from being discharged from the fuel discharge port 110. If possible, anything is possible.

In addition, a part of the fuel transmission member 200 may be exposed to the outside between the first valve member 300 and the tank body 100, and a tank body to one side of a portion of the fuel transmission member 200 exposed to the outside An additional fuel injection port 120a filling the fuel in 100 may be connected. At this time, since the additional fuel injection port 120a is vacuumed by the second valve member 400 mounted on the lower end of the fuel delivery member 200, it may serve to fill the fuel.

As described above, the second valve member 400 may be mounted adjacent to the lower end of the fuel transmission member 200.

The second valve member 400 is for preventing backflow of fuel accommodated in the tank body 100, and when fuel is supplied to the engine, fuel flows from the fuel delivery member 200 to the tank body 100. When the fuel is not supplied to the engine, it is possible to prevent the fuel from being transferred from the tank body 100 to the fuel delivery member 200.

For example, the second valve member 400 may be controlled to open when fuel is supplied to the engine, and may be closed when fuel is not supplied to the engine.

At this time, the second valve member 400 may be provided as, for example, a foot valve, but the configuration of the second valve member 400 is not limited to this, and the reverse flow of fuel accommodated in the tank body 100 Anything is possible if you can prevent it.

Meanwhile, a flow rate measuring member 500 for detecting the amount of fuel in the tank body 100 may be disposed in the tank body 100.

The flow measurement member 500 may be provided with a level switch, for example, and may include a flange 510, a stem 520, a buoy 530, and a stopper 540.

The flange 510 may be mounted on the top surface of the tank body 100.

The stem 520 may have one end connected to the flange 510 and the other end connected to the lower surface of the tank body 100.

The buoy 530 is mounted on the stem 520 and is spaced apart along the longitudinal direction of the stem 520, and may be moved up and down depending on the amount of fuel in the tank body 100. Although it is shown in the drawing that there is one buoy 530, it is natural that the number of buoys 530 may be several.

The stopper 540 is disposed at the top and bottom of the stem 520 to limit the movement of the buoy 530 in the stem 520. Thereby, the buoy 530 can be moved along the stem 520 between the stopper 540 disposed at the top of the stem 520 and the stopper 540 disposed at the bottom of the stem 520.

Specifically, when the fuel in the tank body 100 is filled through the fuel injection port 120 or the additional fuel injection port 120a, the buoy 530 moves upward along the stem 520 and the flow measurement member ( While the flow rate measured through 500) is increased, when the fuel accommodated in the tank body 100 through the fuel discharge port 110 is supplied to the engine, the buoy 530 moves downward along the stem 520 The flow rate measured through the flow rate measuring member 500 may be reduced.

At this time, when the buoy 530 is moved downward along the stem 520 to contact the stopper 540 disposed at the bottom of the stem 520, a control signal is generated to fill the fuel injection port 120 with fuel. Can be.

In particular, the stopper 540 disposed at the lower end of the stem 520 is disposed higher than the lower end of the fuel transmission member 200, so that the lower end of the fuel transmission member 200 can be kept locked at all times.

Meanwhile, a fuel return member 600 may be connected to one side of the tank body 100.

In general, a fuel pump in an engine pumps 250% or more of the required fuel amount, so that 150% or more can be returned at 100% load.

The fuel return member 600 may transfer fuel returned from the engine through the return line R into the tank body 100.

Specifically, one end of the return line R may be connected to the fuel return member 600, and the other end of the return line R may be connected to the return port B of the engine.

At this time, the fuel return member 600 is provided in the form of a drop tube whose end is immersed in fuel in the tank body 100, and the fuel returned through the fuel return member 600 is the lower end of the tank body 100 Can be introduced into the tank body 100 at a location adjacent to it. As described above, when the fuel return member 600 is provided as a drop tube, ignition ignition may be mixed with the liquid and a part may be discharged through the exhaust member 800.

On the other hand, if the fuel return member 600 is not provided as a drop tube, the returned fuel may be scattered into the air due to ignition.

In addition, an overflow member 700 may be connected to one side of the tank body 100.

Generally, since the tank body 100 is legally 1000 liters indoors, excessive fuel may be injected into the tank body 100 due to a valve defect when receiving fuel from the outside.

The overflow member 700 may discharge fuel overflowing from the tank body 100 while the tank body 100 is full.

At this time, the overflow member 700 is provided in the form of a drop tube with the end immersed in fuel in the tank body 100, and the fuel accommodated in the tank body 100 is dropped at a position adjacent to the bottom of the tank body 100. It can be introduced into the tube and transferred to the overflow member 700.

In addition, the exhaust member 800 may be connected to one side of the tank body 100.

The exhaust member 800 is for venting the gas existing in the tank body 100, similar to the vent 130, fuel is injected into the tank body 100 through the fuel injection port 120 or fuel return When the fuel is recovered through the member 600, the pressure in the tank body 100 can be maintained, and the tank body 100 may be exposed to direct sunlight for a long time, the external temperature rises, or the engine may operate due to circulating fuel. As the internal temperature of the body 100 increases, the gas in the tank body 100 expands to prevent abnormal high pressure from being formed.

However, the exhaust member 800 has a difference from the ventilation port 130 in that the exhaust gas existing in the tank body 100 is exhausted when the tank body 100 is full.

In particular, the exhaust member 800 may be formed to protrude from the fuel return member 600 and the overflow member 700 toward the inner space of the tank body 100 from one side of the tank body 100.

At this time, the exhaust member 800 is provided in the form of a drop tube in which the end is kept immersed in fuel in the tank body 100, and the outside air is accommodated in the tank body 100 at a position adjacent to the lower end of the tank body 100. It can be supplied with fuel.

Specifically, the exhaust member 800 should extend at least 12 feet (3.6 meters) from the ground or the bottom of the tank body 100, and need to extend up to 5 feet (1.5 meters) as there is no blockage around. . At this time, a height of 12 feet (3.6 meters) may help ambient air to mix with the gas (vapor) discharged from the tank body 100, so that the atmosphere is maintained below 25% of the flammability limit of the liquid. .

As described above, the ends of the fuel return member 600, the overflow member 700, and the exhaust member 800 are positioned adjacent to the lower surface of the tank body 100 and submerged in the fuel, thereby replenishing, recovering, and overfilling the fuel. Sparks due to static electricity accumulation that may occur due to fuel supplied into the tank body 100 such as a flow can be prevented.

In particular, since the drop tube remains submerged in the fuel within the tank body 100, it can increase the fuel transfer flow rate and reduce ignition fumes, bubbles, and potential fuel evaporation from the tank body 100. It is shown that the fuel return member 600, the overflow member 700 and the exhaust member 800 are arranged side by side on one side of the tank body 100, but the fuel return member 600, the overflow member ( 700) and the arrangement of the exhaust member 800 is not limited to this, the fuel return member 600, the overflow member 700 and the exhaust member 800 may be disposed at different positions in the tank body 100 Is natural.

In addition, although not specifically shown in the drawings, an emergency ventilation member may be disposed on the upper surface of the tank body 100.

The emergency ventilation member is for discharging the gas that expands in the tank body 100 when the exhaust member 800 does not function properly, for example, the emergency ventilation member has a pressure in the tank body 100 of 8 oz (227 g). ), It can be opened to correct the pressure in the tank body 100.

In this way, the tank body 100 is provided with an emergency ventilation member as well as the vent 130 and the exhaust member 800, so that the gas expanded in the tank body 100 can be discharged more effectively, and the tank body 100 The abnormal high pressure can be prevented, and as the fuel in the tank body 100 is consumed, the functional damage of the fuel pump due to the negative pressure generated in the tank body 100 can be prevented.

Thus, the emergency ventilation member can be placed anywhere in the tank body 100 if it can be opened to correct the pressure in the tank body 100.

In addition, a flow rate display member 900 may be mounted on one side of the tank body 100.

The flow rate display member 900 may display the amount of fuel accommodated in the tank body 100 measured by the flow rate measurement member 500.

At this time, the flow rate display member 900 is provided with, for example, a flow rate gauge, and an operator can check the amount of fuel accommodated in the tank body 100 by checking the flow rate display member 900 from the outside.

Particularly, as shown in FIGS. 6 and 7, a seismic fuel tank 10 may be installed around the oil proof jaw, and the oil repellent jaw may be formed to surround the outside of the fuel tank 10. At this time, the area formed by the oil barrier can be formed larger than the area occupied by the lower surface of the fuel tank 10.

In addition, between the tank body 100 and the engine supply line (S) and return line (R) may be installed side by side with each other.

As described above, the seismic fuel tank according to an embodiment may prevent a capillary phenomenon of the tank body 100 to prevent leakage when an earthquake occurs, and fall within the tank body 100 such as replenishment, recovery, overflow of fuel, etc. It can prevent sparks caused by the accumulation of static electricity that can be caused by fuel, increase fuel delivery flow rate and reduce ignition fumes, foaming and potential fuel evaporation. In addition, abnormal high pressure in the tank body 100 may be prevented, and damage to the function of the fuel pump due to negative pressure generated in the tank body 100 may be prevented as fuel in the tank body 100 is consumed.
