A protective sleeve 206 is provided on the outside of the annular limiting member 205, and the protective sleeve 206 matches the shape of the annular limiting member 205. The protective sleeve 206 is made of transparent tempered glass material. A connecting base 207 is bonded to the top of the protective sleeve 206. A limiting hole 208 is provided through the connecting base 207, and a limiting rod body 209 is provided inside the limiting hole 208. The connecting base 207 is slidably connected to the limiting rod body 209 through the limiting hole 208. A column 210 is welded on the top of the translation base 203, and a vertical track groove 211 is provided inside the column 210. A lifting base 212 is provided inside the vertical track groove 211, and the lifting base 212 matches the shape of the vertical track groove 211. The lifting base 212 is slidably connected to the vertical track groove 211. A lifting screw 213 is provided inside the lifting base 212, and the lifting screw 213 is threadedly connected to the lifting base 212. An adjusting motor 214 is provided at the bottom end of the lifting screw 213, and the adjusting motor 214 is fixedly installed at the bottom end of the column 210. The output shaft of the adjusting motor 214 is transmission-connected to the lifting screw 213. A high-definition camera 215 is fixedly installed on one side of the lifting base 212, and the input end of the adjusting motor 214 is connected to a single-chip microcomputer 216. The single-chip microcomputer 216 is an integrated circuit. The integrated circuit chip uses ultra-large-scale integrated circuit technology to integrate a central processing unit (CPU) with data processing capabilities, random access memory (RAM), read-only memory (ROM), multiple I / O ports, an interrupt system, and timers / counters onto a single silicon chip, creating a small but complete microcomputer system. The output of the microcontroller 216 is connected to the input of the hollow shaft drive motor 204. The output of the microcontroller 216 is also connected to a WiFi module 217. WiFi module 217, also known as a serial port Wi-Fi module, belongs to the Internet of Things transmission layer and converts serial or TTL levels into an embedded module that complies with the Wi-Fi wireless network communication standard. It has a built-in wireless network protocol IEEE802.11b.g.n protocol stack and TCP / IP protocol stack, the microcontroller 216 input terminal is connected to the output terminal of the high-definition camera 215;.

[0028] The model of the single chip microcomputer 216 is set to M68HC16, and the model of the WiFi module 217 is set to TLN13UA06.

[0029] The specific implementation method is as follows: when using the present invention, the adjustment motor 214 and the hollow shaft drive motor 204 are controlled by the single chip microcomputer 216, and then the WiFi module 217 can be used to wirelessly connect with external devices such as mobile phones, computers, tablet computers, etc., and then the explosion image taken by the high-definition camera 215 can be transmitted to the single chip microcomputer 216 for processing, and then the image can be sent to the staff through the WiFi module 217. When the adjustment motor 214 is running, since the output shaft of the adjustment motor 214 is connected to the lifting screw 213, the adjustment motor 214 is in a state of rotation. The lifting screw 213 can be driven to rotate. Since the lifting screw 213 is threadedly connected to the lifting base 212, the rotation of the lifting screw 213 can drive the lifting base 212 to move up and down. The lifting base 212 can drive the high-definition camera 215 to move up and down, which can facilitate the adjustment of the high-definition camera 215 to a suitable height, thereby facilitating the shooting of explosion experiments of equipment of different sizes. When the hollow shaft drive motor 204 is running, since the fixed screw 202 is threadedly connected to the hollow output shaft of the hollow shaft drive motor 204, the operation of the hollow shaft drive motor 204 can drive the translation base 2 03 moves in the sliding base groove 201, which can drive the column 210 to move, thereby driving the high-definition camera 215 to move, and can adjust the distance between the lens and the explosion point, so as to facilitate the adjustment of the shooting position and achieve better shooting effects. Then, when the translation base 203 moves, the annular limiter 205 will drive the protective sleeve 206 to move, and then the protective sleeve 206 will slide at the bottom of the limit rod body 209, which can ensure that the protective sleeve 206 can protect the high-definition camera 215 in real time, thereby ensuring its normal operation. Since the protective sleeve 206 is made of transparent tempered glass material, the protective sleeve 206 will not affect the shooting of the high-definition camera 215, and the protection effect is excellent. This enables the device to remotely observe the explosion situation, avoiding the problem that the staff needs to observe the explosion situation around the explosion test device. The observation method is extremely safe. Even if the explosion equivalent is too large, it will not endanger the life safety of the staff. The safety is relatively high. This embodiment solves the problem that most explosion test devices in the prior art use transparent protective covers to cover the explosion area, and then the staff need to observe the explosion situation around the protective cover, resulting in a high work risk factor.

[0030] As attached Figure 1 and attached Figure 2As shown, the present invention provides an explosion test device with a high safety factor, further comprising a shield assembly 3, wherein the shield assembly 3 is arranged outside the monitoring device 2;

[0032] Both ends of the limiting rod 209 are welded to the inner wall of the inner shield 301, and the inner shield 301 and the outer shield 302 are made of titanium alloy material;

[0033] The outer walls of both sides of the outer shield 302 are welded with fixed extension frames 4, and the ends of the fixed extension frames 4 are penetrated by opening and closing screws 5;

[0035] The output shaft of the lifting motor 6 is in transmission connection with the opening and closing screw 5 , and the opening and closing screw 5 is in threaded connection with the fixed extension frame 4 .

[0036] The specific implementation method is as follows: when using the present invention, the single-chip microcomputer 216 can control the operation of the lifting motor 6, and the operation of the lifting motor 6 can drive the opening and closing screw 5 to rotate. Since the opening and closing screw 5 is threadedly connected to the fixed extension frame 4, the rotation of the opening and closing screw 5 can drive the fixed extension frame 4 to move up and down, and the up and down movement of the fixed extension frame 4 can drive the protective cover assembly 3 to move up and down as a whole, thereby achieving the purpose of opening and closing the device. Then, by providing an inner protective cover 301 and an outer protective cover 302, and the inner protective cover 301 and the outer protective cover 302 are both made of titanium alloy material, a double protection effect can be achieved to avoid the explosion experiment affecting the outside world. At the same time, by providing a vacuum chamber 303, a sound insulation effect can be achieved to avoid the noise of the explosion from polluting the environment, thereby making the actual use effect of the device better. This implementation method solves the problem that the explosion test device in the prior art is easy to affect the external environment.

[0038] A circular base 9 is bonded to the top of the buffer base 8 , and the two sliding base grooves 201 are symmetrically arranged on both sides of the top of the circular base 9 .

[0039] The specific implementation method is as follows: when using the present invention, when an explosion test is carried out on the top of the circular base 9, the impact force generated by the explosion will act on the circular base 9, and then the buffer base pad 8 made of rubber material can play a buffering effect to prevent the safety test bench 1 from crushing the ground, so that the actual use effect of the device is better. This implementation method solves the problem in the prior art that when the explosion test device is used, the impact force generated by the explosion acts on the base and easily damages the ground.
