Description

Technical Field

[0001] The present invention relates to the field of civil explosive technology, and in particular to an electronic detonator with a recyclable foot capacitor. Background Art

[0002] With the widespread application of electronic detonators, their production process has become increasingly mature. However, several issues remain in their production and application. First, after the blasting is completed, the internal capacitor of the detonator is destroyed along with the detonator itself, and the leg wires and wire clips cannot be recycled. This causes environmental pollution, wastes resources, and increases the cost of using electronic detonators. Second, the ignition components of most electronic detonators currently require dipping and drying processes. This requires manual operation during the production process, and operator safety cannot be guaranteed. Furthermore, during network testing, detonators with communication anomalies cannot be quickly identified, affecting construction efficiency. Summary of the Invention

[0003] The purpose of the present invention is to solve the above-mentioned existing technical problems and design a leg line capacitor recyclable electronic detonator. After the blasting is completed, the leg line equipped with the capacitor part can be recycled and reused. At the same time, the detonator can be detonated without ignition powder. Magnesium, which is easy to generate electric sparks, is used as a bridge wire instead of the ignition powder head, eliminating the manufacturing and drying of the ignition powder head. In addition, the leg line is also equipped with an audible and visual alarm system to quickly find the detonator with communication errors, thereby improving work efficiency and construction safety.

[0004] To achieve the above object, the present invention adopts the following technical solutions:

[0005] An electronic detonator with a recyclable foot line capacitor comprises a basic detonator, which is composed of a tube shell, a primary charge, a secondary charge, a tertiary charge and a reinforcing cap; an ignition element, a male foot line and a female foot line; the ignition element comprises a magnesium wire, an ignition switch, an electronic control module and a chip pad; the male foot line comprises a chip interface end, an injection molding rubber head, a foot line and a foot line male connector; the female foot line comprises a foot line female connector, a high energy storage capacitor, a buzzer, an LED lamp, a delay control module, a detection communication module and a line card; the ignition element is connected to the male foot line via the chip pad and the chip interface end; the male foot line is connected to the female foot line by inserting the foot line male connector into the foot line female connector; and the female foot line is connected to a general control system via the line card and a blasting busbar.

[0006] One end of the male pin is injection molded into one piece with the chip interface end to form an injection-molded rubber head. The chip pad of the ignition element can be inserted into the chip interface end, and the injection-molded rubber head can be inserted into the tube shell. The injection-molded rubber head is then sealed and fixed by clamping it with a bayonet, and the magnesium wire of the ignition element is placed close to the reinforcing cap.

[0007] The surface of the magnesium wire is covered with a plastic film to prevent the magnesium from being oxidized.

[0008] The master control system includes a screen, power button, mode button, related components, terminals, and a plastic housing. The master control system provides power for the detection and detonation processes. The power button controls the power on and off of the master control system, while the mode button controls the detection and detonation modes of the master control system.

[0009] The general control system can also be connected to a wireless handheld device to realize remote control. The handheld device can realize online checking of detonator communication status, setting of delay time, and detection, detonation and other functions.

[0010] After adopting the present invention, the following beneficial effects are achieved:

[0011] First, the male and female legs are detachable. After installation, the female legs can be partially recycled and reused, reducing environmental pollution caused by discarded legs and lowering the cost of electronic detonators. Second, the ignition element uses magnesium wire as the bridge wire, and the capacitor is external, allowing the use of high-energy storage capacitors. This produces a large flame to detonate the basic detonator, eliminating the need for dipping, reducing the dipping and drying steps in the production process, improving production safety, and reducing production costs. Third, the provision of detection and alarm functions facilitates the rapid identification of detonators with line card connection failures and communication anomalies, providing a clearer investigation target and improving work efficiency.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] like Figure 1As shown, the present invention presents an electronic detonator with a recyclable leg capacitor, which mainly consists of a base detonator, an ignition element, a male leg, and a female leg. The base detonator is ignited by the flame generated by the ignition element; the energy of the ignition element is transmitted from the main control system through the leg.

[0019] The basic detonator consists of a shell 1, a primary charge 2, a secondary charge 3, a tertiary charge 4, and a reinforcing cap 5. The ignition element includes a magnesium wire 6, an ignition switch 7, an electronic control module 8, and a chip pad 9. Because magnesium easily oxidizes, its surface is covered with a plastic film. The electronic control module 8 performs a safety check. If the safety check fails, the ignition element cannot ignite, thus facilitating safety management. The male lead wire includes a chip interface terminal 10, an injection molding head 11, a lead wire 12, and a lead wire male connector 13. The female lead wire includes a female lead wire socket 14, a high-energy storage capacitor 15, a buzzer 16, an LED 17, a delay control module 18, a detection communication module 19, and a line card 20. These wires are used for ignition element communication, safety checks, delay time setting, and energy supply for ignition element charging and firing. The LED indicates the line card connection status. If the line card is successfully connected, the alarm system LED will illuminate; if the line card connection fails, the LED will not illuminate. The energy required by LED is relatively low, with a voltage of 2.5 to 3.2V and a current of 5 to 18mA. One end of the male lead wire 12 is injection-molded into one piece with the chip interface end 10 to form an injection-molded rubber head 11. The chip pad 9 of the ignition element can be inserted into the chip interface end 10, and the injection-molded rubber head 11 can be inserted into the tube shell 1. Then, the injection-molded rubber head 11 is sealed and fixed by clamping it with a bayonet, and the magnesium wire 6 of the ignition element is close to the reinforcing cap 5. The male lead wire and the female base wire are connected by inserting the male lead 13 into the female base 14. The male and female base interfaces are sleeve-type. To separate the interfaces, you only need to press the female base interface. This interface method has good airtightness and good water resistance. The female base wire is connected to the main control system 22 through the line card 20 and the blasting bus 21. The main control system 22 includes a screen 23, a power button 24, a mode button 25, and related components, terminals and a plastic shell. The overall control system can also be connected to a wireless handset 26 for remote control. The handset 26 can perform online checks on detonator communication, set delay times, and perform other functions such as detection and detonation. During the network detection process, if an electronic detonator exhibits communication anomalies, the handset 26 can cause the buzzer 16 of that detonator to sound a warning, allowing for quick identification of the offending detonator.

[0020] The circuit working principle of the present invention is as follows Figure 3As shown. Specifically, after each component is successfully connected, power is provided by the main control system 22. The handset 26 controls the main control system to perform operations such as detection and detonation. During the detection phase, the main control system provides low-voltage current, and the detection communication module 19 performs detection. If the line card 20 is connected normally, the LED light 17 will light up, indicating that the line card 20 is connected normally. If the LED light 17 does not light up, it indicates that the line card is abnormally connected, which can quickly locate the line card with the abnormal connection. If the male and female pins are abnormally connected, the handset 26 can turn on the switch K1, causing the buzzer 16 to sound a prompt, making it easy to quickly find the detonator with the abnormal connection. The electronic control module 8 is used to protect the magnesium wire 6. It can only ignite the magnesium wire 6 with high voltage after passing the low-voltage test. If the low-voltage test is not passed first, and high voltage is applied externally, the electronic control module 8 will automatically disconnect, protecting the magnesium wire and preventing criminal activities. When no abnormality is detected and the delay time setting is completed, the detonation program is entered, the switch K2 is started, the external capacitor 15 is charged, and timing is performed. After the preset delay time is reached, the switch 7 is started to ignite and the detonation process is completed.
