During blasting, the timely and accurate detonation of electronic detonators is crucial for engineering safety. The core component is the electronic module igniter head of the electronic detonator. After receiving the detonation command, the time it takes for the igniter head to ignite varies depending on the type of electronic module igniter head; therefore, the corresponding time delay parameter needs to be tested. Currently, the time delay equipment commonly used in the civil explosives industry is large, inconvenient to operate, and has complex wiring. Summary of the Invention

[0030] To clarify the objectives, technical solutions, and advantages of this invention, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0031] See Figures 1-7 As shown, the present invention provides a device for detecting the detonation vibration of a propellant head, comprising an upper housing 1 and a lower housing 6, wherein the upper housing 1 and the lower housing 6 are connected by screws to form an outer shell;

[0032] The upper housing 1 is provided with an ignition module slot 2 for holding the ignition module, and the upper housing 1 is provided with an elastic clamping member inside, which is located on one side of the ignition module slot 2.

[0033] A vibration sensor 7 is installed inside the lower housing 6, and the vibration sensor 7 is located directly below the ignition module slot 2. A signal interface 10 is provided on one side of the lower housing 6, and the signal interface 10 is connected to the vibration sensor 7 via a signal line. The elastic clamping member consists of a push button 4 and a spring 3. The spring 3 is sleeved on one end of the push button 4, and the push button 4 slides with the upper housing 1. The other end of the push button 4 is inserted into the ignition module slot 2. A pressure block 5 is provided inside the upper housing 1 to clamp the push button 4. The pressure block 5 is connected to the upper housing 1 by screws, and a sliding groove is formed on the pressure block 5 to accommodate the sliding of the push button 4. The push button 4 consists of a top block 4d, a slider 4b, and a tail plate 4a. The top block 4d and the tail plate 4a are respectively located at opposite ends of the slider 4b. The width of the slider 4b is greater than the width of the tail plate 4a. The spring 3 is sleeved on the upper housing 6. On the tail plate 4a, one end of the spring 3 is pressed against the side of the slider 4b, and the other end is connected to the inner wall of the upper housing 1. A push plate 4c is provided on the top of the slider 4b, and a push groove is formed on the top of the upper housing 1 corresponding to the push plate 4c. The push button 4 can slide horizontally along the push groove. With this configuration, in the initial state, the push button 4 is inserted into the ignition module slot 2 under the action of the spring 3. At this time, the push plate 4c is pulled to pull the top block 4d out of the ignition module slot 2, thus exposing the vertical space of the ignition module slot 2. At this time, the ignition module can be inserted into the ignition module slot 2, and its bottom ignition head is pressed against the top surface of the vibration sensor 7. In order to improve the accuracy of vibration detection, the ignition head is positioned at the center of the vibration sensor 7. When the push plate 4c is released, the spring 3 rebounds, which can drive the top block 4d to be inserted into the ignition module slot 2 again to press the ignition module. At this time, the detonator can be connected.

[0034] The outer shell is provided with a pressure relief structure, which is an exhaust groove 11 formed on the surface of the outer shell. The exhaust groove 11 is composed of an upper groove body at the bottom edge of the upper shell 1 and a lower groove body at the top of the lower shell 6, with the upper groove body and the lower groove body corresponding in position. There are three exhaust grooves 11, which are arranged in the middle of the three sides of the outer shell. After the ignition head is detonated, a large amount of gas will be released instantaneously inside the upper shell 1. The exhaust groove 11 is used to discharge the corresponding gas to reduce the impact of the ignition head detonation on the vibration sensor 7. The top surface of the lower shell 6 is provided with an exhaust channel, which is straight and connected to two lower groove bodies at both ends.

[0035] The top surface of the lower housing 6 is provided with a sensor slot that matches the vibration sensor 7. The vibration sensor 7 has a disc-shaped structure and is snapped into the sensor slot. After the vibration sensor 7 is engaged with the sensor slot, the top surface of the vibration sensor 7 is flush with the top surface of the lower housing 6. The ignition module slot 2 is located directly above the center of the vibration sensor 7, ensuring that after the ignition module is inserted, the ignition head is connected to the middle of the vibration sensor 7, thereby improving the accuracy of vibration detection by the vibration sensor 7.

[0036] The bottom of the lower housing 6 is open, and a base plate 8 is provided on the bottom surface of the lower housing 6. The base plate 8 is connected to the lower housing 6 by screws. The bottom surface of the base plate 8 is provided with several pads 9. The pads 9 are made of sponge pads, which are soft and can reduce the impact of surrounding vibrations on the vibration sensor 7. This can improve the stability of the bottom position of the equipment and also play a certain role in shock absorption after the ignition head is detonated. Several vent holes are formed in the middle of the base plate 8. After the ignition head is detonated, it will have a certain impact on the vibration sensor 7, and the vibration sensor 7 will undergo a small deformation. At this time, the internal pressure of the lower housing 6 increases. If a closed structure is used, a large pressure will be generated inside the lower housing 6 at the moment of the ignition head detonation. After impacting the signal wires or connectors inside the lower housing 6, it is easy to cause the signal wires or connectors to loosen. The vent holes can play a certain role in pressure relief and ensure the stable connection between the signal interface 10 and the wires.

[0037] Using the above structure, pull the push button 4 to insert the ignition module into the ignition module slot 2, so that its charge head is connected to the vibration sensor 7. Release the push button 4 to clamp the ignition module. Operate the detonator to initiate the detonation action. The detonator sends an initiation signal to the ignition module. After the initiation signal is processed by the internal electronic module of the ignition module, the initiation energy is transmitted to the charge head through the energy storage element. The charge head detonates. The vibration sensor 7 can then transmit the received charge head detonation signal to the detonator through the signal interface 10 via a signal line. The vibration signal of the charge head detonation is transmitted back to the detonator via the signal line. The initiation operation time and initiation time are recorded by the initiation software. The device can quickly measure the detonation time of the ignition module, and then calculate the delay time required for the actual blasting operation. Compared with traditional second-measurement devices, it is more accurate and easier to operate. The upper shell 1 and lower shell 6 are made of aluminum alloy, which has high structural strength and makes the device more stable and less prone to deformation during use. The device is compact, practical and convenient. It can also provide good external protection when the charge is detonated. After the charge is detonated, the energy of the detonation can be discharged through the exhaust groove 11 to avoid damage to the vibration sensor 7 and the internal wiring of the lower shell 6, further improving the safety of the device.

[0038] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
