Description

Technical Field

[0001] This utility model patent relates to the field of detonator technology, and in particular to an electrothermal detonation device with adjustable parameters. Background Technology

[0002] Accidental detonation or non-detonation after the blasting site has been cleared and secured is considered a major defect. Although this may not cause direct harm to nearby personnel, it poses a great danger if blasting instructions are not followed. Accidental detonation will severely reduce blasting efficiency, increase extra workload, and increase the hazards of flying rocks and earthquake damage. Since unexploded explosives may remain in the blast holes, this creates a hidden danger.

[0003] Inaccurate detonator delay time can have serious consequences, such as increasing the risk of earthquake damage, affecting blasting effectiveness, and generating flyrock. Errors in the calibration of the detonator or detonator delay time adjustment device can also affect the delay. Existing detonator delay devices are prone to inaccurate delay times, or other issues can cause abnormal data in the detonator's internal modules, impacting production safety. When preset parameters need to be adjusted temporarily due to special circumstances, replacing or manually adjusting the equipment introduces errors that affect production safety. Therefore, there is an urgent need to invent an electrothermal detonation device with adjustable parameters to solve the above problems. Utility Model Content

The safety detection module monitors environmental values ​​in real time to ensure the safety and stability of the detonation environment.

[0023] In some embodiments, the time-limiting circuit includes: a calibration module 6, a parameter adjustment module, and a boost module 8. The calibration module 6 is electrically connected to the microprocessor 1, receives instruction information sent by the microprocessor 1, and simultaneously collects time-limiting circuit data and sends the collected information to the microprocessor 1. The microprocessor 1 performs the first verification of the time-limiting circuit. The boost module 8 is electrically connected to the detonating tube. The boost module 8 uses an XC7000B control chip for the calibration module 6. The XC7000B control chip has the advantages of high delay time accuracy and strong anti-interference performance. The parameter adjustment device 7 includes: The circuit includes a variable resistor, bridge wire, relay switch, energy storage capacitor, and filter capacitor. The parameter adjustment device 7 receives signals from the microprocessor 1 to adjust the resistance value of the variable resistor. By adjusting the resistance value, the charging speed and charging time of the energy storage capacitor are adjusted. The filter capacitor stabilizes the circuit voltage, ensuring the accuracy and stability of the detonation signal and indirectly affecting the precision of the detonation time. The boost module 8 includes a transformer, relay switch, transistor, diode, and electrostatic resistor. When static electricity exists in the circuit, the electrostatic resistor quickly discharges the static electricity to protect other components from damage caused by static electricity.

[0024] In some embodiments, the verification module 4 includes an amplifier and an analog-to-digital converter. The amplifier amplifies the time-limited circuit data, and the analog-to-digital converter converts the amplified data and sends it to the microprocessor 1. The data information amplified by the amplifier is used to assist in the secondary data verification, which is more accurate than the first data verification. The microprocessor 1 calculates and compares the amplified data and calculates the correction data. Then, the microprocessor 1 transmits the correction data to the calibration module 6.

[0025] In some embodiments, the authentication module 5 uses fingerprint authentication, password authentication, and / or dynamic data authentication as authentication methods.

It uses 485 communication to connect to the local device, and at the same time uploads data to the cloud for remote monitoring and management through LTE-Cat.1 wireless communication.

[0027] In some embodiments, the microprocessor 1 uses a B660M processor in conjunction with a Renesas RC26008 chip. The Renesas RC26008 chip overclocks the external frequency of the B660M processor, thereby improving the processing performance of the device and making the detonation time more accurate.

[0028] In some embodiments, the regulated battery pack 9 provides regulated power to the circuit system. When the battery capacity is below 10%, it issues a low power alarm to remind the user to power the battery in time.

[0029] Example 1

[0030] In one specific embodiment provided by this utility model, such as Figures 1-4 As shown, this device remotely adjusts the detonation time of the electrothermal detonator through a time-limiting circuit. Before using the equipment, the electrothermal detonator needs to be inspected to ensure its integrity and reliability. The detonation busbar and terminal block are then connected and fixed. The cover is then opened to check the detonator power switch. The LCD screen lights up, and the system enters a self-test state. The Beidou positioning module 3 verifies the device's location information. The battery level of the electrothermal detonator's voltage regulator battery pack 9 is then checked. If the battery level is low, it needs to be charged. Blasting personnel use the identity verification module 5 for fingerprint or password authentication and network debugging. The ZLAN8308 module in the communication module 2 assists the RS485NEESA communication chip to achieve LTE-Cat.1 wireless communication mode. A charge and discharge check is performed to ensure that the high-voltage indicator can rise and discharge normally within the specified time, completing the preliminary equipment preparation work.

[0031] The blasting personnel first lay the blasting busbar from the detonation point to a safe location. They then short-circuit the two connectors of the special probe together, mainly to release the energy stored at the front end. Next, they connect the special probe to the blasting busbar, insert the detonating tube into the special probe, and then connect the blasting busbar to the rear end. After that, they perform a loop test on the detonation circuit to ensure that the loop test values ​​are within the specified range. This device can remotely set the timed detonation time or manually adjust the timed detonation time.

[0032] When an emergency occurs and the detonation time needs to be delayed, the detonation time can be changed through remote or manual settings. After receiving the time change information, the microprocessor 1 performs calculations and sends instructions to the calibration module 6 to control the parameter adjustment device 7 to change the resistance value of the variable resistor. Increasing the resistance value of the variable resistor reduces the current in the circuit, slows down the charging speed of the energy storage capacitor, and prolongs the time required for the energy storage capacitor to reach the detonation trigger condition.
