この考案は芯上下式石油燃焼器に於る自動芯下
げ消火装置に関するものである。[Detailed description of the invention] [Industrial field of application] This invention relates to an automatic wick-lowering fire extinguishing system in a wick-lowering oil combustor.

Since a wick-up and down-type oil combustor can extinguish a fire by lowering the wick into the wick storage cylinder, the wick is raised by rotating a gear equipped with a return spring that rotates around the wick up-and-down axis. Perform the hoisting operation of the return spring,
An automatic fire extinguishing system is known in which the core is lowered via a core vertical axis using the return force of a return spring in the event of an abnormality. Earthquakes are a common abnormality, and when the inverted pendulum that detects vibration falls, the stopper separates from the gear and the return spring automatically extinguishes the fire.
ところで倒立振子の使い方として転倒角度を小

倒角度が小さいことから部品精度の要求が強く、
後者は確実に振子を起すことができるもののセツ
ト操作が必要である。 By the way, there are two ways to use an inverted pendulum: one is to reduce the angle of inversion so that it always stands on its own, and the other is to keep it in an inverted state and raise the pendulum by setting the pendulum.In the former case, because the angle of inversion is small, there is a strong demand for parts precision.
Although the latter can reliably cause the pendulum to swing, it requires a setting operation.

させる提案をしている。 In Utility Application No. 53-156960, the applicant provided a spring for biasing the stopper 6 against the gear 3, formed a toothless portion on the gear 3 facing the stopper 6 at the core lowering position, and applied the spring to the stopper spring. He suggests that the pendulum be erected.

By the way, when detecting vibration with an inverted pendulum,
If the drive plate attached to the movable shaft of the inverted pendulum and the stopper are always in contact with each other, the detected acceleration tends to vary, so the accuracy of the detected acceleration is improved by facing the drive plate and the stopper with a gap in between. In this case, even if the stopper presses the drive plate with the stopper spring to make the pendulum upright, the pendulum may not be able to stand on its own because the gap has no choice but to rely on the self-sustaining function of the inverted pendulum. Said Jitsugan Showa 53
−156960 has a toothless part that makes the self-supporting function easier to operate, and it is also
In No. 60-30416, the toothless part is located deeper than the concave part of the gear to enhance its self-supporting function, and it is a perfect technique for standing a pendulum. However, eliminating the tooth that locks with the stopper poses a problem in operability, even though it is near the core lowering position.If the rotation of the core vertical shaft is stopped during core raising operation, the gear will idle until it reaches the next tooth.
In particular, in order to make the pendulum easier to stand, the larger the toothless part, the greater the idling distance, which became dangerous.
