Description

Technical Field

[0001] The utility model relates to the technical field of pyrotechnic detonation control, in particular to an underwater electronic detonator detonation control device and a detonation control system. Background Art

[0002] At present, electronic detonators are widely used in tunnel excavation, hazard removal blasting, demolition blasting, ore-rock separation, open-pit mine blasting, underwater blasting projects and other occasions; during the detonation operation, the electronic detonator and the wire clamp are connected by a connecting leg wire, the wire clamp is connected to the control bus, and the control bus is connected to the detonation controller. The detonation controller transmits the detonation signal to the control circuit board of the electronic detonator through the control bus and the connecting leg wire. 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 can easily fall off the wire clamps, causing the electronic detonators to fail to fire, affecting the quality and reliability of the underwater blasting.

[0004] Furthermore, when controlling the detonation of electronic detonators arranged underwater, it is often necessary to float the detonation controller in the water. In order to achieve the floating arrangement of the detonation controller in the water, the prior art connects the detonation controller to a floating body. However, under the influence of water flow and wind and waves, the detonation controller is easily wetted by the 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
