Portable underwater blasting shock wave suppression device

The utility model provides a portable underwater blasting shock wave suppression device which comprises a gas cylinder, a gas outlet pressure-bearing pipe, a setting device, a connecting pressure-bearing pipe and a bubble generation device, the gas cylinder is communicated with the setting device through the gas outlet pressure-bearing pipe, and the setting device is communicated with the bubble generation device through the connecting pressure-bearing pipe. Wherein the setting device is linked with an external detonating system, when the external detonating system is started, the setting device is triggered, and finally a bubble curtain is generated to restrain shock waves. The device is suitable for underwater blasting engineering under various complex environmental conditions, and can be used for synchronously generating a large number of bubble curtains when underwater blasting with large position change in a construction area is implemented, so that the functions of inhibiting underwater blasting shock w
