Their complex design and numerous components not only increase manufacturing complexity and cost, but also make them prone to failure during use. Furthermore, the high failure rate significantly inconveniences drilling operations, making repairs difficult for on-site personnel. Due to their complex structure, maintenance personnel often spend considerable time and effort troubleshooting the problem, severely impacting drilling efficiency. Furthermore, the high cost of existing ignition system parts increases operating costs for companies. Utility Model Content

[0022] Reference Figure 1-4The oil drilling ignition device provided by the utility model includes: a main power switch 1, a power output circuit of the main power switch 1 is connected to a battery 3, a power output circuit of the battery 3 is connected to an ignition head selection module 4, a power output circuit of the main power switch 1 is connected to an ignition mode selection module 5, a power output circuit of the main power switch 1 and the ignition mode selection module 5 is connected to a transformer 6, a secondary side output circuit of the transformer 6 is connected to a rectifier bridge 7, a DC output circuit of the rectifier bridge 7 is connected to a high-energy ignition module 8; the high-energy ignition module 8 includes a first DC circuit 801, a second DC circuit 802, a resistor 803, a high-energy ignition The discharge tube 804, the ignition capacitor 805, the first spark plug 806, the second spark plug 807 and the spark plug grounding terminal 809, the DC output end of the rectifier bridge 7 is provided with a first DC circuit 801 and a second DC circuit 802, the first DC circuit 801 is provided with a resistor 803, a high-energy ignition discharge tube 804, the first spark plug 806 and the second spark plug 807 in sequence, the second DC circuit 802 is provided with an ignition capacitor 805, the ignition capacitor 805 circuit is connected to the first DC circuit 801 between the resistor 803 and the high-energy ignition discharge tube 804, and the end of the second DC circuit 802 is provided with a spark plug grounding terminal 809.

[0023] When the main power switch 1 is turned on, part of the current flows to the battery 3 for charging, while the remaining live current enters the ignition mode selection module 5. After the desired ignition mode is selected by the ignition mode selection module 5, the current reaches the transformer 6. The transformer 6 converts the input current into a voltage, and its secondary output is connected to the rectifier bridge 7. The rectifier bridge 7 converts the AC power into DC power, providing a stable DC power supply for the high-energy ignition module 8.

[0024] In the high-energy ignition module 8, the first DC circuit 801 and the second DC circuit 802 work together. The ignition capacitor 805 charges and interacts with the high-energy ignition discharge tube 804 to generate a high-energy spark. Ignition is achieved through the resistor 803, the high-energy ignition discharge tube 804, the first spark plug 806, and the second spark plug 807. A spark plug grounding terminal 809 is provided at the end of the second DC circuit 802 to ensure proper grounding. This dual DC circuit design makes the ignition process more stable and reliable.

[0025] The ignition head selection module 4 includes an ignition head selection switch 401, a first DC contactor coil 402 and a second DC contactor coil 403. The two power output terminals of the battery 3 are sequentially connected to the first DC contactor coil 402 and the second DC contactor coil 403.

[0026] Battery 3 serves as a power source, with its two output terminals connected to DC contactor coil No. 1 402 and DC contactor coil No. 2 403, respectively. Ignition head selector switch 401 controls the on / off switching of the two DC contactor coils. When ignition head selector switch 401 is switched to different positions, the corresponding DC contactor coils are energized. When the selector switch is switched to the position connecting to DC contactor coil No. 1 402, DC contactor coil No. 1 is energized, thereby triggering the corresponding ignition head. When the selector switch is switched to the position connecting to DC contactor coil No. 2 403, DC contactor coil No. 2 is energized, activating the other ignition head.

[0027] The ignition mode selection module 5 includes a fuse 501, a mode selection switch 502, a local ignition button 503, and a remote control button 504. The power output circuit of the main power switch 1 is connected to the fuse 501, the output circuit of the fuse 501 is connected to the mode selection switch 502, and the two output ends of the mode selection switch 502 are connected to the local ignition button 503 and the remote control button 504 in sequence. The output circuits of the main power switch 1, the local ignition button 503 and the remote control button 504 are connected to the transformer 6.

[0028] After the main power switch 1 is turned on, the live wire current first enters fuse 501 in the ignition mode selection module 5. Fuse 501 acts as an overcurrent protector. The current flowing out of fuse 501 enters mode selector switch 502, which has two options: local ignition and remote control ignition. When remote control ignition is selected, the remote control button 504 is remotely operated and requires additional power. One output terminal of the battery 3 is connected to the remote control button 504, providing it with a stable power supply. When local control ignition is selected, it can be directly activated using the mechanical key of the local ignition button 503. This allows current to flow through transformer 6, achieving remote ignition. The two ignition modes of local ignition and remote control provide great convenience for the operator. In different working environments, the operator can choose the most appropriate ignition mode according to the actual situation, improving work flexibility and efficiency.

[0029] A power supply circuit 505 is connected between the battery 3 and the remote control button 504 , and there are two power supply circuits 505 .

[0030] A power supply circuit is connected between the battery 3 and the remote control button 504. When remote control ignition is required, the battery 3 provides a stable power supply to the remote control button 504 through the power supply circuit. The power supply circuit ensures that the remote control button 504 can work normally.

[0031] The end circuit of the first DC circuit 801 is connected to two normally open contacts 808 , and the two normally open contacts 808 are connected to the No. 1 spark plug 806 and the No. 2 spark plug 807 in sequence.

[0032] Under normal circumstances, normally open contact 808 is in an open state, preventing current from flowing through the spark plugs. When the ignition signal is triggered, the high-energy ignition discharge tube 804 discharges or the ignition capacitor 805 releases energy, normally open contact 808 quickly closes, allowing current to flow smoothly through spark plugs 806 and 807, generating sparks and achieving ignition.

[0033] The main power switch 1 is circuit-connected with a power indicator light 2 .

[0034] When the main power switch 1 is turned on, current passes through the power indicator light 2, causing it to light up, so that the operator can intuitively understand whether the device is in a power-on state.

[0035] Working Principle: When the main power switch 1 is turned on, current flows to the battery 3 for charging and to the fuse 501 for overcurrent protection. Then, the mode selector 502 is used to select local ignition or remote ignition. If local ignition is selected, pressing the local ignition button 503 causes current to flow to the transformer 6. If remote ignition is selected, the remote control button 504 is triggered, and the battery 3 provides power to the remote control button 504 through the power supply circuit, causing current to flow to the transformer 6.

[0036] The transformer 6 performs voltage conversion on the input current, and the secondary side output end thereof is connected to the rectifier bridge 7 .

[0037] Rectifier bridge 7 converts AC power into two DC currents. First DC circuit 801 and second DC circuit 802 work together to charge ignition capacitor 805, which interacts with high-energy ignition discharge tube 804 to generate a high-energy spark. Ignition is achieved through resistor 803, high-energy ignition discharge tube 804, spark plug 1 806, and spark plug 2 807. Meanwhile, ignition head selector switch 401 in ignition head selector module 4 can select different ignition heads as needed.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
