[0002] Rock breaking technology is a key link in marine engineering, oil exploration, underwater construction and other underwater operations. Traditional underwater blasting technology usually uses chemical explosives, but this method has certain environmental risks and operational complexity. With the increasing attention to environmental protection and operational safety, the market demand for a safer and more environmentally friendly rock breaking technology is growing. Liquid oxygen blasting, as an emerging technology, uses liquid oxygen (LOX) as an oxidant to accelerate the combustion process through its high oxygen content and strong oxidizing properties, thereby achieving effective crushing of underwater rocks. This technology shows the potential for efficient destruction and disintegration of targets in the mining, construction and demolition industries, and has the characteristics of low vibration, weak destructive power to the surrounding environment, environmental protection and safety.

[0003] At present, liquid oxygen blasting technology has been applied in some fields. Its working principle is to use the physical properties of liquid oxygen to achieve the blasting effect. Liquid oxygen blasting devices usually include liquid oxygen supply system, blasting tube, ignition system and other components. In underwater environment, liquid oxygen blasting devices need to overcome the influence of water pressure to ensure the effective transmission of blasting energy. Existing liquid oxygen blasting devices may have some limitations in design, such as stability in deep water conditions, control of blasting accuracy and ability to resist water flow impact.

[0004] Although liquid oxygen blasting technology provides a relatively environmentally friendly and safe method of breaking rocks, it still faces some challenges when applied underwater. First, the complexity of the underwater environment, including changes in water flow, buoyancy and water pressure, may cause the blasting device to shift and affect the blasting accuracy.

[0031] When in use, firstly, a blast hole is opened at a predetermined position, and then the container body 1 is placed inside the blast hole, and then the electronic valve 2 17 is opened to change the internal air pressure of the high-pressure chamber 16, and the gas is pushed into the ejection chute 15, and at the same time, the ejection rod 14 is pushed to move along the length direction of the ejection chute 15, so that the ejection rod 14 pushes the transmission slide block 12 to move along the length direction of the transmission chute 11, so that the transmission slide block 12 drives the transmission rack 13 to move along the length direction of the transmission chute 11, and meshes with the transmission gear 10, so that the transmission gear 10 drives the resistance rod 9 to expand outward around the hinge axis, and drives the roller 18 to form rolling resistance with the inner wall of the blast hole, so as to maintain the stable shape of the container body 1 inside the blast hole; Then, the regulating slurry 22 is started to drive the water flow through the drainage port 20 into the thrust chamber 19, and then discharged from the thrust chamber 19 through the drainage port 21, so as to push the container body 1 to drive the roller 18 to roll along the inner wall of the blast hole. At the same time, a protective net 23 is set to intercept and filter the water flow passing through the drainage port 20 and the drainage port 21, so as to reduce the damage caused by foreign matter in the water flow to the regulating slurry 22; When the container body 1 moves to a predetermined position along the length direction of the blasthole, the adjusting slurry 22 is closed, and the resistance rod 9 is used to push the roller 18 to resist the inner wall of the blasthole, so that the container body 1 is fixed at a predetermined position in the blasthole, thereby facilitating the adjustment and fixation of the blasting installation position of the container body 1 and effectively improving the blasting accuracy of the device.

[0036] The implementation principle of an underwater liquid oxygen rock breaking device in this embodiment is as follows: first, a blasthole is opened at a predetermined position, and then the container body 1 is placed inside the blasthole. Then, the electronic valve 2 17 is opened to change the internal air pressure of the high-pressure chamber 16, and the gas is pushed into the ejection chute 15.
