Description

Technical Field

[0001] The present invention relates to an electronic pulse ignition device, in particular to an electronic pulse ignition device with adjustable optical fiber trigger delay for impact, belonging to the technical field of electronic pulse ignition. Background Art

[0002] There is a pulse high-frequency oscillator inside the electronic pulse ignition device. The high-frequency voltage generated by the oscillator is boosted to a high voltage by a step-up transformer for tip discharge. The whole process generates a high-voltage electrical pulse through an electronic circuit. This pulse generates an electric spark through a discharge gap, and the cut-off wave truncation time is 2 - 5 μS. Currently, the application of electronic circuit delay in impact devices in the market is very rare. Impact device manufacturers use traditional LC circuit delay. By changing the taps of the inductor and capacitor, the truncation time is changed, and the signal is connected to the wave tail resistor. Therefore, as the high voltage passes through the LC circuit to reach the cut-off wave device, the LC circuit must be placed in oil. The whole device is large and heavy. At the same time, the high voltage easily damages the inductor and capacitor in the LC circuit. In addition, some transformer manufacturers also choose cable delay, placing the cable on a cable reel, resulting in a substantial increase in production costs.

[0003] In addition, if the gap between the carrier spheres is too large, it may lead to unstable discharge and difficult ignition; if the gap is too small, it may damage the ignition needle or electrode due to overly concentrated discharge. Therefore, adjusting the gap can optimize the ignition effect and make the ignition more rapid and reliable. The existing carrier spheres are fixedly arranged, and the gap between the carrier spheres cannot be adjusted, resulting in poor application range and flexibility.

[0004] Therefore, it is urgent to improve the electronic pulse ignition device with adjustable optical fiber trigger delay to solve the above existing problems. Summary of the Invention

[0005] The purpose of the present invention is to provide an electronic pulse ignition device with adjustable optical fiber trigger delay for impact, which combines the charge and discharge principle of a capacitor and CR delay. During impact discharge, the high-voltage pulse capacitor is detected, and a voltage drop generates a pulse to trigger the optical fiber isolation trigger high-voltage pulse circuit. The optical fiber isolation trigger high-voltage pulse circuit is based on the received pulse trigger circuit. After the trigger circuit passes through RC delay, it is then triggered by a triode and an optocoupler isolation trigger circuit, triggering the triode Q1. Short-circuiting the capacitor C1 will cause the capacitor to discharge and generate a pulse signal. The high voltage converts the pulse capacitor into an optical signal, effectively isolating the high voltage from the low voltage and ensuring the reliability of the trigger circuit loop.

[0038] 1. By combining the charge and discharge principle of a capacitor with CR delay, high-voltage pulse capacitance detection is performed during impulse discharge. When the voltage drops, a pulse is generated to trigger the fiber optic isolation trigger high-voltage pulse circuit. The fiber optic receiver triggers the trigger circuit based on the received pulse.

Detailed implementation manners

[0051] The following will cooperate with the drawings and embodiments to detail the implementation manners of the present application, so as to fully understand the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects and implement accordingly.

[0052] Such as Figures 1-9As shown in the figure, the electronic pulse ignition device with adjustable optical fiber trigger delay for impact provided in this embodiment includes an ignition device 100 and an ignition control circuit 200. The ignition device 100 includes a support platform 1 and a carrier sphere 4 provided on the support platform 1. The carrier sphere 4 includes an upper carrier sphere 401 and a lower carrier sphere 402. A regulating mechanism 2 is connected to the bottom of the lower carrier sphere 402. The regulating mechanism 2 is used to adjust the gap between the upper carrier sphere 401 and the lower carrier sphere 402. By generating high-frequency oscillation and boosting voltage, the ignition device 100 is such that the size of the discharge gap directly affects the voltage required for ignition and the stability of the discharge. Adjusting the gap can ensure that the discharge can occur stably and effectively at a specific voltage, thereby improving the ignition success rate;

[0053] To facilitate the adjustment of the gap between the upper carrier sphere 401 and the lower carrier sphere 402, the regulating mechanism 2 includes an adjusting roller 201, a vertical transmission rod 204, a horizontal transmission rod 207, and a vertical slider 5 that are sequentially rotatably connected. The vertical slider 5 is fixedly provided at the bottom of the lower carrier sphere 402. The adjusting roller 201 rotates the horizontal transmission rod 207 through the vertical transmission rod 204. A driving gear 208 is fixedly provided at one end of the horizontal transmission rod 207. A driving strip 502 is provided inside the vertical slider 5. The driving gear 208 is meshed with the driving strip 502. The horizontal transmission rod 207 is used to vertically push the lower carrier sphere 402. By rotating the adjusting roller 201, the vertical transmission rod 204 is driven to rotate. While the vertical transmission rod 204 is rotating, it drives the rotation of the horizontal transmission rod 207. While the horizontal transmission rod 207 is rotating, the regulating mechanism 2 drives the driving strip 502 to move through the driving gear 208. The driving strip 502 drives the vertical slider 5 to move vertically, thereby adjusting the gap between the lower carrier sphere 402 and the upper carrier sphere 401. The structure is simple and the convenience of use is improved. Specifically:

[0054] One end of the adjusting roller 201 is connected with a first small driving bevel gear 202. One end of the vertical transmission rod 204 is connected with a first large driven bevel gear 203 meshed with the first small driving bevel gear 202. When the adjusting roller 201 rotates, it drives the rotation of the first small driving bevel gear 202. The first small driving bevel gear 202 drives the vertical transmission rod 204 to rotate by driving the first large driven bevel gear 203. Since the diameter of the first small driving bevel gear 202 is smaller than that of the first large driven bevel gear 203, the purpose of the first differential speed is achieved during the transmission of the vertical transmission rod 204. The first small driving bevel gear 202 is used to rotate the first large driven bevel gear 203. The bottom of the vertical transmission rod 204 is connected with a second small driving bevel gear 205. One end of the horizontal transmission rod 207 is provided with a second large driven bevel gear 206 meshed with the second small driving bevel gear 205. When the vertical transmission rod 204 rotates, it drives the rotation of the second small driving bevel gear 205 at the bottom. When the second small driving bevel gear 205 rotates, it drives the horizontal transmission rod 207 to rotate through the second large driven bevel gear 206. Since the diameter of the second small driving bevel gear 205 is smaller than that of the second large driven bevel gear 206, the purpose of the second differential speed is achieved. The second small driving bevel gear 205 is used to rotate the second large driven bevel gear 206. A slider driving groove 501 is formed inside the vertical slider 5. A driving strip 502 is fixedly arranged on one side of the slider driving groove 501 and meshed with the driving gear 208. When the driving gear 208 rotates, the driving strip 502 meshed with the driving gear 208 will drive the vertical slider 5 to move up and down, thereby achieving the purpose of adjusting the gap between the upper carrier sphere 401 and the lower carrier sphere 402. One end of the driving gear 208 is rotatably connected with a positioning plate 209. The positioning plate 209 is fixedly arranged on the bottom side of the support table 1. When the horizontal transmission rod 207 rotates, the driving gear 208 is used to vertically push the vertical slider 5. The upper side of the vertical slider 5 is fixedly connected with the lower carrier sphere 402 through a sphere connecting block 503. The lower carrier sphere 402 is fixedly connected with the vertical slider 5 through the sphere connecting block 503. When the vertical slider 5 moves vertically, it will drive the lower carrier sphere 402 to move up and down, thereby achieving the purpose of adjusting the gap;

[0055] Therefore, during the process of manually rotating the adjusting roller 201, through the setting of the two differential speeds, even if the adjusting roller 201 is rotated quickly, the movement speed of the lower carrier sphere 402 will not be too fast. Of course, the main purpose is to adjust the gap between the upper carrier sphere 401 and the lower carrier sphere 402, which is suitable for fine adjustment, that is, it can not only expand the scope of use, but also ensure the stability of discharge. A suitable discharge gap helps to form a stable and strong electric spark;

The optical fiber receiver triggers the triode Q1 through a triode and an optocoupler isolation trigger circuit. The capacitor C1 is short-circuited. After the capacitor C1 is short-circuited, it discharges. The discharge voltage generates a high-voltage of 16000V through a transformer, and a discharge spark is generated at the discharge gap.

A fixed time constant τ is formed by the combination of resistor R and capacitor C. The delay loop selection circuit 10 selects the corresponding channel through optocoupler group isolation, and the selected channel uses a self-locking button;

[0068] The principle of capacitor charge and discharge and CR delay are combined. During impulse discharge, the high-voltage pulse capacitor is detected. The voltage drop generates a pulse to trigger the fiber optic isolation trigger high-voltage pulse circuit. The fiber optic receiver triggers the loop according to the received pulse. After the trigger loop passes through RC delay, it is then triggered by the triode and optocoupler isolation trigger circuit to trigger the triode Q1. Short-circuiting the capacitor C1 will cause a pulse signal to be generated, which is amplified 40 times by the transformer to form a 16000V high-voltage pulse signal. The high voltage converts the pulse capacitor into an optical signal, effectively isolating the high voltage from the low voltage. The designed circuit uses a high-voltage isolation power supply to effectively isolate the voltage of 2kV, ensuring the reliability of the trigger circuit loop.
