Description

Technical Field

[0001] The present invention belongs to the field of wave-dissipating devices, and particularly relates to a floating bubble curtain wave-blocking system. Background Art

[0002] With the rapid development of the country's infrastructure, infrastructure projects have continuously extended to waters such as the ocean, lakes, rivers, and harbors; more and more underwater projects need to be completed by blasting construction. With the development of blasting technology, especially the wide application of millisecond blasting technology, the amount of explosive charge detonated at one time in underwater blasting has been increasing. However, at the same time, with the improvement of living standards and environmental protection awareness, people's requirements for the safety protection of underwater blasting and the protection of underwater organisms are also getting higher and higher. How to reasonably set blasting parameters and reasonably use blasting barriers has gradually become a new research direction for blasting construction units.

[0003] Studies have shown that the bubble curtain can effectively disrupt the waveform of the blasting shock wave, thereby significantly achieving the effect of wave dissipation. Therefore, the bubble curtain technology is being applied by more and more construction units in blasting operations. The existing bubble curtains mostly adopt the method of setting bubble pipelines around the blasting point, and ventilating air below the water surface through an air compressor to form a bubble group. The vibration generated by the bubbles in the water body is used to disrupt the shock wave spreading outward from the blasting point, thereby achieving the purpose of wave dissipation. However, the existing bubble curtains cannot be installed and operated independently, and need to be bundled and supported by external objects, with poor mobility. Moreover, when jetting air, due to the buffering effect of the jet pressure, the bubble pipelines will twist and the jet direction is not fixed, so that a bubble curtain cannot be formed.

When the tightening bolt 150 is tightened, the ends of the two tightening bolts 150 can move into the through slot 104 and tighten the two sides of the U-shaped clamp 140, which can drive the clamping mouth of the U-shaped clamp 140 to narrow.

[0042] In addition, a first pull ring 108 is fixedly installed on the top of the suspension 100, and a second pull ring 109 is fixedly installed on both sides of the suspension 100. There are multiple suspensions 100, and the suspensions 100 are connected to each other through a first chain 200. The two ends of the first chain 200 are respectively connected to the second pull ring 109 in a detachable manner. When the working environment requires, the first chain 200 can be used to connect the suspensions 100 into a ring structure to surround the blasting point, thereby achieving a better wave-breaking effect.

[0046] Next, the working principle of a floating bubble curtain wave blocking system in this embodiment will be described in detail so that those skilled in the art can better understand the present invention:

[0047] During use, the suspension bodies 100 are first moved to a designated position around the blasting point, and the suspension bodies 100 are connected to each other with the first chain 200 so that the suspension bodies 100 surround the blasting point. Then, a main line 500 of corresponding length is installed according to the depth of the blasting point, so that one main line 500 is installed between every two adjacent suspension bodies 100. Then, as needed, a bubble line 600 is installed on each quick-connect connector 502 of the main line 500, and the main line 500 and the second chain 300 are tied together with a cable tie, and the bubble line 600 and the third chain 400 are tied together, so that the bubble line 600 can always be deployed underwater under the counterweight of the third chain 400. Then, the rotation direction of the rotating nozzle 612 in the nozzle assembly 610 is adjusted so that the rotating nozzle 612 on each bubble pipeline 600 is alternately arranged vertically and horizontally. Then, the high-pressure air pipe on the reef blasting ship is connected to the air inlet 501 in the main pipeline 500. High-pressure gas is ejected outward from the nozzles 613 at both ends of the rotating nozzle 612, forming three layers of bubbles on both sides and in the middle of each bubble pipeline 600, thereby increasing the bubble density of the entire bubble curtain.

[0048] To sum up, the floating bubble curtain wave-blocking system in this embodiment adopts an independent and freely sliding floating body to suspend the bubble pipeline 600 to generate a bubble curtain. It can work independently without the help of additional climbing objects for support and has strong maneuverability. The main pipeline 500 and the bubble pipeline 600 are fixed by the counterweights of the second chain 300 and the third chain 400, thereby stabilizing the pipe body when the nozzle 613 assembly sprays, preventing twisting due to the aftereffect of air pressure, and making the bubble curtain more stable.
