Technical Field
[0001] This invention relates to the field of detonator testing equipment technology, and in particular to an industrial digital electronic detonator shock wave resistance testing device and testing method. Background Technology
[0002] Electronic detonators, also known as digital detonators, digital electronic detonators, or industrial digital electronic detonators, are electric detonators that use electronic control modules to control the detonation process. As a mainstream product representing the future development trend of detonating materials in my country, electronic detonator technology has made significant progress and is widely used in blasting engineering. However, research on the reliability of electronic detonators is still insufficient. In actual blasting operations, the blast shock wave from the first blast hole acts on the electronic detonator in the subsequent blast hole, causing misfires and missed shots, which is particularly prominent in tunnel blasting operations.
[0003] Currently, there is no complete device or method for assessing the damage of explosive shock waves to industrial digital electronic detonators. Therefore, how to provide a shock wave resistance testing device and method for industrial digital electronic detonators is an urgent problem to be solved by those skilled in the art. Summary of the Invention

To this end, one objective of this invention is to provide a shock wave resistance testing device and method for industrial digital electronic detonators. This invention uses water as the medium for shock wave propagation, ensuring good repeatability of the test conditions; it can quantitatively evaluate the shock wave resistance of electronic detonators, providing the pressure range that can withstand the shock wave, and offering accurate test data for manufacturers to improve product structure and performance.
[0005] An industrial digital electronic detonator shock wave resistance testing device according to an embodiment of the present invention includes a lifting bracket, an explosion water tank disposed below the lifting bracket, and a test fixing frame disposed on the side of the explosion water tank;
[0006] The top of the lifting support is equipped with a horizontal slide rail, with the sliding surface of the horizontal slide rail facing downwards. A lifting motor is slidably installed inside the horizontal slide rail, and the output end of the lifting motor is connected to a hook via a lifting rope.
[0007] Preferably, the explosion water tank includes a barrel body, a shock-absorbing pad is installed on the bottom surface of the barrel body, and an inlet and outlet water pipe is provided on the bottom side of the barrel body.
[0008] Preferably, the barrel body includes an outer stainless steel layer, and the outer stainless steel layer is lined with an impact-resistant layer.
[0009] Preferably, the impact-resistant layer is a closed-cell plastic foam.
[0010] Preferably, the test fixture includes a frame, on both the upper and lower surfaces of which are installed crosswise fixing rods. Multiple mounting holes are equally spaced on the sides of the upper and lower fixing rods, and a lifting hook is installed on the top surface of the fixing rod.
[0011] Preferably, the top surface of the lifting motor is equipped with a slider adapted to the transverse slide rail, and the lifting motor is slidably mounted on the transverse slide rail via the slider.
[0012] Preferably, the transverse slide rail is an electrically controlled slide rail.
[0013] Preferably, the testing method includes the following steps:
[0014] S1. A main explosive charge consisting of one electronic detonator and industrial explosives is detonated underwater to generate a shock wave. The outer shell is made of waterproof kraft paper, rolled by hand, with an inner diameter of 25mm and a length of 25mm. The upper and lower ends of the charge are tied together with connecting wires and suspended on the test fixture. Using the same method, the electronic detonator to be tested and the underwater shock wave sensor are also suspended on the test fixture, so that the centroids of the main explosive charge, the chip of the electronic detonator to be tested, and the underwater shock wave sensor are at the same horizontal position. The underwater shock wave sensor is located at a distance of R = 40-50cm from the centroid of the main explosive charge, and the electronic detonator to be tested is located at a distance of R = 5-20cm from the centroid of the main explosive charge. The underwater sensor is connected to the underwater explosion shock wave test system.
[0015] S2. For the initial test, the mass of the industrial explosive is 15g. The distance between the test sample and the main explosive charge is 20cm. The test fixture is hoisted into the explosion water tank using a lifting bracket, so that the main explosive charge is 0.9-1m below the water surface.
[0016] S3. Set the delay time of the electronic detonator in the main explosive charge to 0ms and the delay time of the electronic detonator under test to 20ms. Detonate the electronic detonator with the detonator. After detonation is completed, lift the test fixture with the lifting bracket and observe the electronic detonator under test.
[0017] S4. If the electronic detonator fails to detonate, the amount of the main explosive charge remains unchanged. Using d as a increment of 5cm, continue increasing the distance between the test sample and the main explosive charge. Repeat steps S2 and S3 until the electronic detonator detonates normally. At this point, the horizontal distance L between the test electronic detonator and the main explosive charge is recorded. The pressure P at the underwater shock wave sensor is recorded using an underwater shock wave tester. c During the repeated operation of steps S2 and S3, the horizontal distance R between the underwater shock wave sensor and the main explosive is changed, and α and β are fitted to obtain the peak pressure of the underwater explosion shock wave of this type of industrial explosive.
[0018]
[0019] Among them, Pm To calculate the peak pressure of the shock wave of type m industrial explosive, the unit is Pa, W is the weight of the main charge package, the unit is Kg, R is the horizontal distance between the main charge package and the sensitive element of the underwater shock wave sensor or the centroid of the tested electronic detonator, R0 is the radius of the main charge package, the unit is m, and α and β are coefficients and exponents.
[0020] Substituting the distance L from which the tested electronic detonator can detonate normally into R in the formula yields the critical pressure P of the electronic detonator affected by the shock wave. L ;
[0021] S5. If the electronic detonator explodes, the delay time of the electronic detonator of the main explosive is still set to 0ms. The test sample is detonated without a delay time, the main explosive charge is detonated, and the test results are observed.
[0022] S6. If the electronic detonator still explodes, continue to increase the distance between the test sample and the main explosive charge in increments of d (5cm) until the electronic detonator no longer explodes. Repeat S5. If the electronic detonator does not explode, continue to decrease the distance between the test sample and the main explosive charge to 15cm in increments of d (5cm). Repeat S5 until the electronic detonator explodes.
[0023] S7. Increase the gradient distance by 5cm and repeat S3. If the electronic detonator can detonate normally, it means that the tested electronic detonator can withstand the shock wave without being affected.
[0024] Preferably, the main explosive charge, the electronic detonator under test, and the underwater shock wave sensor are all suspended between the upper and lower fixed rods by connecting wires. The two ends of the connecting wires are respectively fixed in the mounting holes on the upper and lower fixed rods, and the chip of the electronic detonator under test is on the same plane as the centroid of the main explosive charge.
[0025] Preferably, in step S3, the electronic detonator under test is observed. If the electronic detonator does not detonate, the state of the electronic detonator is detected using an initiator. If the electronic detonator chip cannot communicate, the detonator head is damaged, or other components such as capacitors are damaged, it can be determined that "hard damage" has occurred due to the shock wave. If the electronic detonator can communicate and detonate normally, it is determined to be "soft damage," meaning that the electronic chip cannot detonate the electronic detonator normally under the action of the shock wave, but it recovers its function after the impact.
[0026] Compared with the prior art, the beneficial effects of the present invention are:
[0027] (1) This invention uses water as the propagation medium for the shock wave. Because water is homogeneous and slightly compressible, it exhibits the same equation of state under normal temperature and pressure conditions. When the main explosive charge detonates in water, the interface between the explosive products and the water generates a shock wave with abrupt, strong discontinuities. The waveform characteristics are obvious, and the system can easily collect characteristic numerical data. The peak pressure P of the shock wave... m It is used to characterize the performance of the tested sample, and therefore has high repeatability.
[0028] (2) The present invention uses the peak pressure P of the explosion shock wave m As a quantitative indicator for measuring the shock wave resistance of electronic detonators, the test sample is tested through systematic testing to provide the pressure range that it can withstand from shock waves, providing accurate test data for manufacturers to improve product structure and enhance product performance.

Detailed Implementation
[0035] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.
[0036] refer to Figure 1-3An industrial digital electronic detonator shock wave resistance testing device includes a lifting bracket 1, an explosion water tank 2 disposed below the lifting bracket 1, and a test fixing frame 3 disposed on the side of the explosion water tank 2.
[0037] A horizontal slide rail 5 is installed on the top of the lifting bracket 1, and the sliding surface of the horizontal slide rail 5 is set downward. A lifting motor 4 is slidably installed inside the horizontal slide rail 5. The output end of the lifting motor 4 is connected to a hook 7 through a lifting rope 6.
[0038] The explosion-proof water tank 2 includes a barrel body 21, with a shock-absorbing pad 22 installed on the bottom surface of the barrel body 21, and inlet and outlet water pipes 23 opened on the bottom side of the barrel body 21. The barrel body 21 includes an outer stainless steel layer 211, and an impact-resistant layer 212 is lined inside the outer stainless steel layer 211. The impact-resistant layer 212 is a closed-cell plastic foam with a thickness of 40mm.
[0039] In this embodiment, the explosion water tank 2 is used to hold tap water to simulate the underwater explosion environment of a detonator. It is designed as a cylinder with an inner diameter of 1.8m, a depth of 1.8m, and a wall thickness of 30mm. It is made of high-strength stainless steel with seamless welding process. It is equipped with two pre-installed lifting handles and a water supply and drainage system. The explosion water tank 2 must be guaranteed to be leak-free.
[0040] The test fixture 3 includes a frame 31, which is used to fix the sample and sensor assembly. The frame 31 has cross-arranged fixing rods 32 installed on both the top and bottom surfaces. Multiple mounting holes 34 are evenly spaced on the sides of the fixing rods 32. Lifting hooks 33 are installed on the top surface of the fixing rods 32. A slider adapted to the transverse slide rail 5 is installed on the top surface of the lifting motor 4. The lifting motor 4 is slidably mounted on the transverse slide rail 5 via the slider. The transverse slide rail 5 is an electrically controlled slide rail. The lifting of the test fixture 3 can be automatically controlled by a controller.
[0041] In this embodiment, the shock wave testing system was developed by Chengdu Taize Technology Co., Ltd., and consists of a BLAST-PRO shock wave tester and a PCB underwater shock wave sensor. The PCB underwater shock wave sensor is a 138 series ICP tourmaline underwater explosion pressure sensor, and the electronic detonator is a commercially available electronic detonator. The shock wave tester has a maximum sampling frequency of 10MHz (0.25μs), a minimum sampling frequency of 250kHz (4μs), and a dynamic response of 100dB. The shock wave sensor has a maximum response pressure of 345MPa, a sensitivity of 0.073mV / kPa, and a resolution of 0.14kPa, which can meet the testing requirements for underwater explosion shock waves and bubble pulsation waves.
[0042] The test method in Example 1 includes the following steps:
[0043] S1. A main explosive charge consisting of one No. 8 electronic detonator and industrial explosives, specifically Class I rock emulsion explosives with a detonation velocity ≥4200m / s, explodes in water to generate a shock wave. Its outer shell is made of waterproof kraft paper, hand-rolled, with an inner diameter of 25mm and a length of 25mm. It is an approximately spherical charge with a charge radius R0 = 12.5mm. The upper and lower ends of the charge are tied together with connecting wires and suspended on the test fixture 3. Using the same method, the electronic detonator to be tested and the underwater shock wave sensor are also suspended on the test fixture 3, ensuring that the centroids of the main explosive charge, the chip of the electronic detonator to be tested, and the underwater shock wave sensor are at the same horizontal position. The underwater shock wave sensor is located R = 40cm away from the centroid of the main explosive charge, and the electronic detonator to be tested is located R = 5cm away from the centroid of the main explosive charge. The underwater sensor is connected to the underwater explosion shock wave test system.
[0044] S2. For the initial test, the mass of the industrial explosive is 15g. The distance between the test sample and the main explosive charge is 20cm. The test fixture 3 is hoisted into the explosion water tank 2 using the lifting bracket 1, so that the main explosive charge is 0.9m below the water surface.
[0045] S3. Set the delay time of the electronic detonator in the main explosive charge to 0ms and the delay time of the electronic detonator under test to 20ms. Detonate the electronic detonator with the detonator. After detonation is completed, lift the test fixture 3 with the lifting bracket 1 and observe the electronic detonator under test.
[0046] In S3, observe the electronic detonator under test. If the electronic detonator does not explode, use the detonator to check the status of the electronic detonator. If the electronic detonator chip cannot communicate, the detonator head is damaged, or other components such as capacitors are damaged, it can be judged that "hard damage" has occurred due to the shock wave. If the electronic detonator can communicate and detonate normally, it is judged as "soft damage", that is, the electronic chip cannot detonate the electronic detonator normally under the action of the shock wave, but it recovers its function after the impact.
[0047] S4. If the electronic detonator fails to detonate, the amount of the main explosive charge remains unchanged. Using d as a increment of 5cm, continue increasing the distance between the test sample and the main explosive charge. Repeat steps S2 and S3 until the electronic detonator detonates normally. At this point, the horizontal distance L between the test electronic detonator and the main explosive charge is recorded. The pressure P at the underwater shock wave sensor is recorded using an underwater shock wave tester. c During the repeated operation of steps S2 and S3, the horizontal distance R between the underwater shock wave sensor and the main explosive is changed, and α and β are fitted to obtain the peak pressure of the underwater explosion shock wave of this type of industrial explosive.
[0048]
[0049] Among them, P mTo calculate the peak pressure of the shock wave of type m industrial explosive, the unit is Pa, W is the weight of the main charge package, the unit is Kg, R is the horizontal distance between the main charge package and the sensitive element of the underwater shock wave sensor or the centroid of the tested electronic detonator, R0 is the radius of the main charge package, the unit is m, and α and β are coefficients and exponents.
[0050] Substituting the distance L from which the tested electronic detonator can detonate normally into R in the formula yields the critical pressure P of the electronic detonator affected by the shock wave. L ;
[0051] While performing steps S1 to S4, the underwater shock wave testing system continuously changes the distance R within a range of 40-50cm. In this embodiment, R = 40cm is selected. After measuring the data, the underwater explosion shock wave calculation formula for this type of explosive is obtained by fitting the data. When the electronic detonator can be detonated normally in step S4, and the distance between the tested electronic detonator and the main charge is L, L is substituted into the formula (R in the formula) to obtain the pressure at the tested electronic detonator.
[0052] S5. If the electronic detonator explodes, the delay time of the electronic detonator of the main explosive is still set to 0ms. The test sample is detonated without a delay time, the main explosive charge is detonated, and the test results are observed.
[0053] S6. If the electronic detonator still explodes, continue to increase the distance between the test sample and the main explosive charge in increments of d (5cm) until the electronic detonator no longer explodes. Repeat S5. If the electronic detonator does not explode, continue to decrease the distance between the test sample and the main explosive charge to 15cm in increments of d (5cm). Repeat S5 until the electronic detonator explodes.
[0054] S7. Increase the gradient distance by 5cm and repeat S3. If the electronic detonator can detonate normally, it means that the tested electronic detonator can withstand the shock wave without being affected.
[0055] The main explosive charge, the electronic detonator under test, and the underwater shock wave sensor are all suspended between the upper and lower fixed rods 32 via connecting wires. The two ends of the connecting wires are respectively fixed in the mounting holes 34 on the upper and lower fixed rods 32, and the chip of the electronic detonator under test is on the same plane as the centroid of the main explosive charge.
[0056] Example 2: The apparatus and method steps of this example are the same as those of Example 1, except that the underwater shock wave sensor is located at a distance of R = 50 cm from the centroid of the main explosive charge, the electronic detonator under test is located at a distance of R = 20 cm from the centroid of the main explosive charge, and the main explosive charge is located 1 m below the water surface.
[0057] Example 3: The apparatus and method steps of this example are the same as those of Example 1, except that the underwater shock wave sensor is located at a distance of R = 45 cm from the centroid of the main explosive charge, the electronic detonator under test is located at a distance of R = 15 cm from the centroid of the main explosive charge, and the main explosive charge is located 0.95 m below the water surface.
[0058] The underwater shock wave resistance performance of the m-type electronic detonator was tested according to the steps of Example 1 above. The test results are shown in Table 1.
[0059] Table 1
[0060]
[0061] It should be noted that "damaged" means that the tested electronic detonator cannot be activated normally and that the components have suffered physical damage; "intact (unexploded)" means that the tested electronic detonator cannot be activated normally and that it is intact when tested with an initiator.
[0062] This invention uses the peak pressure P of the explosion shock wave m As a quantitative indicator for measuring the shock wave resistance performance of electronic detonators, the pressure range that the test sample can withstand is given by systematic testing. As shown in Example 1, the pressure range for "hard damage" and "soft damage" is 112.27-51.69 MPa. This provides experimental data for manufacturers to improve product structure and enhance product performance.
[0063] This invention uses water as the propagation medium for shock waves. Because water is homogeneous and slightly compressible, it exhibits the same equation of state under normal temperature and pressure conditions. When the main explosive charge detonates in water, the interface between the explosive products and the water generates a shock wave with abrupt, strong discontinuities. The waveform characteristics are distinct, and the system can easily collect characteristic numerical data. The peak pressure P of the shock wave... m It is used to characterize the performance of the tested sample, and therefore has high repeatability.
[0064] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
