Timing ignition power supply capable of storing for long time

Abstract

The timing ignition power source comprises a timing mechanism and a driving power source, the driving power source comprises a battery, a voltage stabilizing circuit and a super-capacitor, the battery charges the super-capacitor through the voltage stabilizing circuit, and an electrode A and an electrode B are arranged at the two ends of the super-capacitor respectively. The electrode B is connected with the timing mechanism through the switch tube, one group of terminals of the double-pole-double-throw switch is arranged between the timing mechanism and the driving power supply, and the other group of terminals of the double-pole-double-throw switch is arranged among the electrode A, the electrode B and the driving power supply. Long-term effective storage of the battery on the timing switch can be ensured, and the validity period of the timer can be ensured to be 10 years.

Description

technical field [0001] The invention relates to the technical field of timing ignition, in particular to a timing ignition power supply that can be stored for a long time. Background technique [0002] Timing ignition is an ignition method that is widely used at present. For example, some blasting devices need to be moved to a safe area to start blasting after the switch is manually turned on, so as to ensure the personal safety of construction workers. Some blasting devices require a delay in the explosion time. Long, some explosive devices require a short delay time, therefore, many timing switches can set the delay time as needed. For example, in the current blasting operation, a lead wire is used, and the burning process of the lead wire is used to consume time. The length of the delay time can be set by the length of the reserved lead wire. This is a very primitive timing switch. This timing switch is basically no longer used during blasting operations at present. Bec...

Problems solved by technology

[0003] At present, there is a kind of timing switch, which relies on two electrodes to discharge when the timing time is up to realize timing signal output. If there is a gunpowder explosive device, it usually needs to be stored for a long time. Once it needs to be used, it can be taken out immediately. This kind of gunpowder When the explosive device is detonated, it uses two electrode discharges to cause the gunpowder to explode. It also uses a timing switch to delay the explosion. Due to the long-term storage process, there will be some electric energy leaking between the output poles of the switch. When it is used, Due to long-term discharge, the voltage of the power supply is not enough to discharge the two electrodes of the timing switch, resulting in failure to detonate, and the battery on the timing switch will also fail due to long-term discharge
