The magnetic sensing device 9 comprises a set of magnet means 91 connected by a connecting rod which is connected to the leaf fan 8 via a linkage shaft 10. When the leaf fan 8 rotates, it will drive a group of magnet devices 91 to rotate together, convert the energy passing through the material, convert it into electric energy through the first coil 11, and control it through the integrated circuit 14, for the second The coil 12 is discharged.

The present invention provides a safety protection device 100 having three states - a setting (condition) state, a standby (operating) state, and a braking state. Specifically:

Setting (condition) state: As shown in FIG. 2-4, the driving block 32 is first pulled by an external force (hand pull) and pulled to the baffle 7, and the first one-way sawtooth 34 is under the action of the magnetic device 33. It will move along with the drive block 32. As shown in FIG. 2-3, since the first one-way sawtooth 34 is unidirectional, when the outer gear 35 is engaged therewith, when the first one-way sawtooth 34 moves toward the pipe inlet 51, the outer gear 35 does not rotate; At the baffle 7, the external force is removed, and the first one-way sawtooth 34 is moved toward the fixing member 6 by the elastic member 31 while the first one-way sawtooth 34 is driven by the magnetic attraction device 33 to the duct outlet 52.

The direction moves, which in turn drives the interceptor connecting rod 38 to move toward the bottom, and finally drives the intercepting plug 40 to move toward the base to separate from the duct outlet 52, so that the plug 40 is in an open state.

Standby (operating) state: As shown in FIG. 4, the plug 40 is in an open state, and substances (such as electricity, gas, oil, water, etc.) can enter through the duct inlet 51 and flow out from the duct outlet 52.

Braking state: When the condition is satisfied (for example, the energizing time satisfies the set time, the water passing time satisfies the set time, etc.), as shown in FIG. 4-8, the integrated circuit 14 of the control unit 1 is converted by the first coil 11. The second coil 12 can be discharged, and the block 13 is moved, so that the transmission block 32 is disengaged from the block 13 and continues to move toward the fixing member 6 under the elastic deformation force of the elastic member 31, and Driving the first one-way sawtooth 34 to continue to move in the same direction, and disengaging the first one-way sawtooth 34 from the external gear 35 (as shown in FIG. 7); at this time, the plug 40 is under the action of the power driving device 39, Moving toward the duct outlet 52, and driving the interceptor connecting rod 38, the second one-way serration 37 also moves toward the duct outlet 52, and the internal gear 36 that cooperates with the second one-way serration 37 rotates. Until the plug 40 closes the conduit outlet 52, it is in a closed state (as shown in Figure 1). At this point, the substance stops transporting, ensuring ease of use and safety.

As shown in FIG. 5, in order to increase the airtightness of the shutoff plug 40, a groove portion 53 is provided at the pipe outlet 52, and the plug portion 40 is provided with a boss portion 41 correspondingly fitted to the groove portion 53. In the braking state, the boss portion 41 of the plug 40 is engaged in the groove portion 53 of the duct outlet 52 to effect sealing.

As shown in Figure 9, L1 is rectified and filtered by D3&D4&D6&D7&C1, inputting energy for the control unit, and charging to E1 via D1.

T1&T2&T5&D2&R1&R4&R5&R6&R9&R10&R11&C2 are charging voltage detection circuits.

When the E1 voltage value accumulates to the set detection value, the above circuit will be locked by D5 feedback, so that E1 will brake the L2 discharge.

T3&T4&R2&R3&E2&R7 are discharge time detection circuits.
