The digital electronic detonator has the characteristics of accurate time delay, safe use and the like, is widely applied to open blasting operation, and is gradually popularized and applied in the industries of roads, railway tunnels, water conservancy and hydropower engineering and the like in recent years. When the digital electronic detonator is used, the internal capacitor is carried by the digital electronic detonator, so that the external power is not required to be supplied, and only the special detonator is required to transmit an excitation signal to trigger the internal capacitor to discharge to complete the detonation process. In the process of using the digital electronic detonator, the detonator is often incapable of being detected and incapable of being detonated normally after being arranged in a blast hole, which brings great potential safety hazard to site construction; therefore, before blasting operation is carried out by adopting the digital electronic detonator, single shot detection work is carried out on the corresponding detonator, and normal work of each component is ensured.

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1 to 2, the embodiment provides a single-shot safe explosion-proof device that detects of digital electronic detonator, including sealed device casing 1, device casing 1 is the square box that is formed by six heavy steel sheet welding that cover of 40cm х 40cm, and the last roof of device casing 1 is provided with wooden handle 2, conveniently transports, removes whole device. The inner wall of the device shell 1 is laid with a porous sound absorption material layer through strong glue to absorb the explosion sound generated during explosion.

The device comprises a device shell 1 and is characterized in that a dense mesh partition plate 3 is anchored at the middle inside the device shell 1 through rivets, the dense mesh partition plate 3 is also a heavy-duty steel plate, a plurality of dense mesh holes are formed in the plate, the upper side of the dense mesh partition plate 3 is an explosion-proof detection area, the lower side of the dense mesh partition plate 3 is an explosion-proof pressure release area, a detonator box inlet opening 4 is formed in the explosion-proof detection area, a protection plate 5 opened towards the inner side of the device shell 1 is hinged at the box inlet opening 4, a pressure release opening 6 is formed in the explosion-proof pressure release area, the number of the pressure release openings 6 is even, at least two pressure release openings are formed, and the pressure release openings are symmetrically arranged on two opposite side walls of the device shell 1. The pressure relief opening 6 is hinged with a pressure relief plate 7 which is opened towards the outer side of the device shell 1, the protection plate 5 and the pressure relief plate 7 are both made of heavy-duty covering plates, the size of the box inlet 4 is 15cm х 5cm, the size of the protection plate 5 is 20cm х 10cm, the size of the pressure relief opening 6 is 15cm х 10cm, and the size of the pressure relief plate 7 is 20cm х 15 cm.
