The delay control chip in the electronic detonator presets the delay time, and the control circuit board issues a detonation command according to the preset delay time, thereby realizing the detonation control of multiple electronic detonators respectively.

[0003] However, when electronic detonators are used in underwater blasting construction, the wire clamps have low waterproof performance. As the time the wire clamps are immersed in water increases, the risk of water entering the wire clamps and causing leakage and short circuits increases, which in turn causes some electronic detonators to fail to detonate normally. Furthermore, when the wire clamps are arranged in water, under the influence of water flow and wind and waves, the connecting leg wires are easily detached from the wire clamps, causing blind shots of the electronic detonators, affecting the quality and reliability of the underwater blasting.

[0004] Furthermore, when the detonation control of the electronic detonator arranged underwater is performed, it is often necessary to float the detonation controller in the water. In order to achieve the floating setting of the detonation controller in the water, the detonation controller is connected to a floating body in the prior art. However, under the influence of water flow and wind and waves, the detonation controller is easily wetted by the surge waves and even immersed in water, affecting the stability of the detonation controller. Therefore, there is an urgent need for a detonation control device that is conducive to improving the reliability of underwater blasting. Summary of the invention
