It is configured. When refueling a cartridge with this kerosene tank device, position the fuel filler port of the cartridge directly under the fuel filler pipe, insert the fuel filler pipe into the fuel filler port, and then open the open / close cock to release kerosene from the fuel filler pipe to the fuel filler port. Let it flow down. Then, after the cartridge is almost filled with kerosene, the opening / closing cock is closed to complete the refueling of the cartridge.

[0003]

[Problems to be solved by the device]

 However, in the conventional kerosene tank system, it is necessary to monitor when the kerosene is full by the side of the cartridge. This is because kerosene continues to be supplied to the cartridge unless the opening / closing cock is closed, and if the opening of the opening / closing cock is delayed due to lack of oil, kerosene will overflow from the filling port of the cartridge. Therefore, when refueling a refueled container such as a cartridge, it is necessary to attend to the side of the refueled container to watch that the kerosene is full, so there is the inconvenience of not being able to do other work during refueling. .

The present invention has been made in order to solve the above-described inconvenience, and it is not necessary to monitor whether kerosene is full when refueling a container to be refueled. A kerosene tank device that can be used for business is provided.

[0005]

[Means for Solving the Problems]

 A kerosene tank device according to the present invention is attached to a kerosene tank body, an oil supply valve attached to the bottom of the kerosene tank body, an oil supply pipe connected to the oil supply valve, and an oil supply pipe opposite to the oil supply valve side. , The oil level detection sensor that outputs an oil level detection signal when it detects that the distance to the oil level has dropped below a specified value, and the oil level detection signal is supplied from this level sensor And a valve drive mechanism that puts the oil supply valve into the oil supply stop state.

[0006]

[Action]

 When the refueling valve according to the present invention is in a refueling state, the kerosene in the kerosene tank body flows down from the refueling pipe to the refueled container. Then, when the oil level rises due to the oil supply to the oil-supplied container, and the distance between the oil level and the oil level detection sensor falls below a predetermined value, the oil level detection sensor outputs an oil level detection signal to the valve drive mechanism. Therefore, the valve drive mechanism brings the refueling valve in the refueling state into the refueling stop state.

Next, when the ON switch 72n is operated, the control unit to which the ON signal is supplied rotates the transfer oil motor 73 once in the counterclockwise direction, so that the needle 23 meshed with the drive gear 74 and the rack 23r becomes a coil spring. Since it moves to the right against the biasing force of 26, the outflow hole 22h is opened, and the oil supply valve 21 is in the oil supply state as shown in FIG.

Therefore, refueling from the kerosene tank body 1 to the cartridge C is started. When the oil level is raised in the cartridge C and approaches the oil level detection sensor 61, and the oil level detection sensor 61 is immersed in kerosene, for example, the oil level detection sensor 61 outputs an oil level detection signal. The control unit to which the oil level detection signal is supplied sets the once-transfer oil motor 73 to the unloaded state. Therefore, the needle 23 moves leftward by the urging force of the coil spring 26 and closes the outflow hole 22h, so that the oil supply valve 21 is in the oil supply stop state as shown in FIG.

If it is desired to stop or interrupt the refueling while the cartridge C is being refueled, the off switch 72f is operated, and the control section to which the off signal is supplied once causes the transfer oil motor 73 to be unloaded as described above. Since the needle 23 moves to the left due to the biasing force of the coil spring 26 and closes the outflow hole 22h, the refueling valve 21 is in the refueling stopped state as shown in FIG.

As described above, according to the first embodiment of the present invention, when the kerosene is supplied to the cartridge C, when the kerosene becomes full, the oil supply to the cartridge C is automatically stopped. There's no need to watch for kerosene filling by your side. Therefore, while the fuel is being supplied to the cartridge C, other work can be performed with peace of mind. Further, since the opening / closing cock 11 is provided between the kerosene tank body 1 and the oil supply valve 21, even if the oil supply valve 21 fails and remains in the oil supply state, the opening / closing cock 11 is operated to supply oil. be able to.

Furthermore, since the bellows pipe 31 is provided between the oil supply valve 21 and the oil supply pipe 41 so that the bellows pipe 31 can be expanded and contracted to displace the oil supply pipe 41, the bellows pipe 31 can be displaced when no oil is supplied. Can be reduced to retract the refueling pipe 41 to a position where it does not get in the way. Since the handle 51 is provided on the oil supply pipe 41 to form a clip, the oil supply pipe 41 can be fixed to the cartridge C by this clip.

First, when the needle 23 is pressed to the right in the state shown in FIG. 6, that is, in a state where the needle 23 has closed the outflow hole 22h of the oil supply valve body 22 by the biasing force of the coil spring 26 and the oil supply valve 21 is in the oil supply stopped state, The outflow hole 22h is opened, and the protrusion 23d rotates the locking lever 77 clockwise against the biasing force of the torsion spring 78. Then, when the projection 23d is sufficiently pressed to the right, the locking lever 77 rides over the projection 23d and is rotated counterclockwise by the biasing force of the torsion spring 78 to engage with the projection 23d. As shown in FIG. 7, the refueling valve 21 is in a refueling state.

Next, when the oil level detection signal is output from the oil level detection sensor 61 or the off switch 72f is operated, the control section energizes the solenoid of the solenoid magnet 79 for a predetermined time, for example, 2 seconds. Is attracted against the urging force of the torsion spring 78, and the locking lever 77 rotates clockwise, so that the needle 23 moves leftward by the urging force of the coil spring 26 and closes the outflow hole 22h. As shown in FIG. 6, the refueling valve 21 is in a refueling stopped state.

As described above, also in the second and third embodiments, the same effect as in the first embodiment can be obtained. In the second embodiment, the cam 74A may be rotated by approximately 90 degrees in order to bring the refueling valve 21 into the refueling stop state. In addition, in the third embodiment, the refueling valve 21 is brought into the refueling stop state. In addition, the solenoid magnet 79 may be operated for, for example, 2 seconds, so that the responsiveness of bringing the refueling valve 21 into the refueling stop state is improved. Further, in the third embodiment, since the solenoid magnet 79 may be energized only when the refueling valve 21 is in the refueling stop state, the life of the battery 75, which is the power supply, can be extended.

In each of the above-described embodiments, an example in which the opening / closing cock 11, the bellows tube 31, and the handle 51 are provided has been described, but these are not always necessary. Also, it goes without saying that the structure of the valve drive mechanism may be any other structure as long as the oil supply valve 21 functions similarly. Further, the oil supply valve 21 may be a solenoid valve, and the solenoid valve may be a valve drive mechanism that functions similarly to the oil supply valve 21.
