  This invention makes it a subject to provide the fire extinguishing (combustion stop) apparatus of microcomputer timer control for extinguishing automatically in the passage of setting time in the oil combustion apparatus which is not connected with commercial power (AC100V power supply). .

Microcomputer control timer device that generates a fire extinguishing signal after a certain period of time, an electromagnetic solenoid that causes the solenoid drive piece to rotate the sensing rotation lever in the unlocking direction by its electromagnetic operation, and a fire extinguishing signal input from the microcomputer control timer device An electromagnetic solenoid circuit in which a switch, an electromagnetic solenoid, and a battery power source connected in series with each other are connected in series, and a rotation prevention lock mechanism for a core up / down lever in the core lowering fire extinguishing device,
The rotation blocking lock mechanism is
The core up / down lever for operating the core lowering fire extinguishing device by core lowering is urged to rotate in the operating direction,
A lock pin (fire extinguishing base pin) 7 is provided to prevent the pivot of the lead up / down lever from rotating in the operating direction, and the lock pin is configured to be unlocked by the sense pivot lever. Coordinate with the operation of the descending fire extinguishing system .
Further, with respect to the core up / down lever 2 for operating the core lowering type fire extinguishing device by the core lowering, the pin 2b is protruded toward the fire extinguishing board 5 at the middle part thereof, and the length of the pin 2b engaged with the fire extinguishing board 5 A hole 5b is formed so that the core up / down lever 2 can freely rotate within the range of the rotation restriction by the long hole 5b, and the core up / down lever 2 can be independently operated even in the set state of the rotation prevention lock mechanism. It is characterized by that.

The present invention automatically generates a fire extinguishing signal after the set time has elapsed under the control of the microcomputer, releases the locked state of the core upper and lower levers through the operation of the electromagnetic solenoid, and immediately lowers the core to extinguish the fire ( since those combustion stop) to, without the need for commercial power, Ru can operate Sahoru microcomputer-controlled extinguishing system a battery as a power source.
Also in the set state of the pivoting blocking lock mechanism, because the freely alone manual operation of the core upper and lower levers 2, by a manual operation of the core upper and lower levers 2, prior to the operation check of the automatic fire extinguishing system, a shared member It has the effect of confirming the operation of a certain core lowering fire extinguisher.

  A microcomputer-controlled timed automatic fire extinguishing apparatus A showing a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

1 and 2, 1 is an electromagnetic solenoid device, 2 is a core up / down lever of a core lowering fire extinguishing device, 3 is a sensing rotation lever, 3a is a sensing lever shaft, 4 is a substrate, 5 is a fire extinguishing substrate, 6 refueling extinguishing lever, 7 Ru der (the lock pin to the core up and down lever) extinguishing board pin.

A lever bearing 4b is mounted on a substrate shaft 4a protruding from the substrate 4, and the core up / down lever 2 is rotatable around the lever bearing 4b . A fire-extinguishing board 5 is pivotally supported on the lever bearing 4b between the board 4 and the core up / down lever 2.

  Due to the presence of the pin 2b of the core up / down lever 2 and the long hole 5b of the fire extinguishing substrate 5, only the core up / down lever 2 can be operated alone. That is, the core up / down lever 2 can be freely operated in the set state of the core up / down lever 2.

  When the electromagnetic solenoid device 1 is operated and the fire extinguishing board 5 is rotated in the direction B by the engagement between the lower end extension bent piece 5c of the fire extinguishing board 5 and the lower end 2c of the core up / down lever 2, the core up / down lever 2 is moved to the fire extinguishing board. 5 and rotate together.

Next, the rotation prevention lock mechanism B will be described.
The fire extinguishing board pin (lock pin) 7 protruding from the end of the fire extinguishing board 5 is restricted by the guide long hole 4e of the board 4 and the guide hole 5e of the fire extinguishing board 5 to limit the rotation range of the fire extinguishing board 5. Further, due to the presence of the lock step portion 5f formed at the lower end of the guide hole 5e, the fire extinguishing board pin (lock pin) 7 is engaged with the lock step portion 5f in the set state of the vibration detection device 1, and the rotation is prevented. The Therefore, the fire extinguishing board 5 is urged to rotate in the operating direction by the spring body 8, but is restricted by the lock structure to maintain the standby state.

  FIG. 7 shows the vertical positional relationship between the action piece 14 and the sensing protrusion 30 at the electromagnetic operating position of the electromagnetic solenoid 10. That is, the two come into contact with each other, the action piece 14 rises, and the sensing rotation lever 3 is rotated. As a result, the locked state of the rotation prevention lock mechanism B, that is, the locked state of the core up / down lever is released.

The microcomputer 43 generates a fire extinguishing signal K when the set time elapses with the timer function. For example, when the operation switch S is turned on, the microcomputer 43 starts a timer count, outputs an alarm signal K0 to the alarm means 44 after 2 hours and 50 minutes, and outputs a fire extinguishing signal K0 to the switch 42 after 3 hours. Therefore, a microcomputer control program is set, and the microcomputer control type timer device is configured by microcomputer controlling the operation of the electromagnetic solenoid 10 .
