Problems solved by technology
At present, domestic research on in-situ flow rate online measurement devices for submarine cold seep natural gas seepage has been carried out. Our country is blank in this field. However, due to the limitations of materials, components, power consumption and poor performance stability of the two sets of devices successfully developed, it is difficult to carry out long-term multi-environmental principle of natural gas flow in the submarine cold seepage system. bit online observation

The invention discloses a seafloor cold spring natural gas leakage bubble breaking device which comprises a support assembly, a power transmission and bubble breaking assembly and a honeycomb core plate. The support assembly comprises a lower support, a supporting plate, a honeycomb core plate installation plate and an upper support which are sequentially arranged from bottom to top, the power transmission and bubble breaking assembly comprises a supporting ring, an impeller shaft, an impeller and a bubble cutter, the honeycomb core plate is installed in the honeycomb core plate installation plate, the supporting plate is fixed to the outer side of the supporting ring, the impeller shaft is arranged in the supporting ring in a penetrating mode, the impeller which is fixedly connected to the lower end of the impeller shaft is located in a lower central through hole formed in the lower support, and the bubble cutter fixedly connected to the upper end of the impeller shaft is located in an upper central through hole formed in the upper support. According to the seafloor old spring natural gas leakage bubble breaking device, the impeller is driven by kinetic energy generated by rising of bubbles to rotate, no extra energy is needed, and the device can be adapted to the environment of different water depths, and is simple in structure and reliable in operation.
Description
technical field [0001] The invention relates to the design of a bubble crushing device in an in-situ ultrasonic measurement device for measuring the seepage flow of natural gas in seabed cold springs, especially for preprocessing the shape of bubbles before measuring the flow of bubbles in seabed seepage with an acoustic method, so as to obtain accurate measurement result. Background technique [0002] The in-situ measurement device for the seepage flow rate of submarine cold seep natural gas is a new technology that has been researched and developed abroad in the past ten years, and the research in this field is being carried out in full swing internationally. The United States regards deep-sea technology as a high-tech project with priority funding in its ocean field. In 1998, Professor Harry Roberts of the Coastal Research Institute of Louisiana State University designed and manufactured a submarine cold seep fluid observation device, and successfully observed the natura...
