Embodiment 1

[0023] This embodiment provides a seabed bubble generation simulation device, such as figure 1 As shown, it includes an air supply device 2, a bubble generator 47, a first floating body 5, a second floating body 7, a tripod 41, an acoustic releaser 8 and a counterweight 9, the air supply device 2 is connected to the bubble generator 47, and the first The floating body 5 is arranged in the tripod 41 , and the second floating body 7 , the acoustic releaser 8 and the counterweight 9 are connected in sequence.

[0024] Gas supply device 2 is water equipment, providing gas, such as figure 2 As shown, it includes a high-pressure gas storage tank 21, a pressure reducing valve 22 and a high-pressure air pipe 3 connected in sequence. High-pressure gas is stored in the high-pressure gas storage tank 21, and the pressure reducing valve 22 is installed at the outlet of the high-pressure gas storage tank 2. By adjusting the pressure reducing valve, the higher gas pressure before the valv...

Embodiment 2

[0031] This embodiment provides another seabed bubble generation simulation device, which is different from Embodiment 1 in that the gas supply device is set 2 underwater, such as Figure 5 As shown, the high-pressure gas storage tank 21 is a mounted gas cylinder, which is arranged on the cable above the second floating body 7 . This simulation does not require an on-board ship or platform to work, therefore, it is simpler to operate and has a wider range of applications. After the test was completed, the deck sonar controller issued a release command, the acoustic releaser released the cement counterweight, the underwater equipment surfaced under the action of buoyancy, and the crew on the rear deck of the ship recovered the underwater equipment.

Abstract

The invention provides a seabed bubble generation simulation device. The seabed bubble generation simulation device comprises a gas supply device, a bubble generator, a floating body, an optical releaser and a counterweight block, wherein the bubble generator comprises an exhausting spraying nozzle; the lower side of the exhausting spraying nozzle is connected with a tapered container; the taperedcontainer is filled with sand gravels; a straight pipe is arranged at a tail part of the tapered container; the straight pipe is connected with a high-pressure gas pipe; the floating body comprises afirst floating body and a second floating body; the first floating body is arranged in a triangular bracket; the triangular bracket comprises an upper-layer plate and a lower-layer plate; a space forcontaining the first floating body is formed between the upper-layer plate and the lower-layer plate; the bubble generator is fixedly arranged on the upper-layer plate; monitoring equipment is arranged above the bubble generator; the bottom of the triangular bracket is connected with the optical releaser and the counterweight block through a cable; the cable is provided with a second floating body and a hanging ring; two ends of the hanging ring are arranged at two sides of the second floating body. The simulation device can be used for simulating seabed overflowed gas under a natural state and the technological development of detection of seabed hydrates and the like is promoted.

Description

technical field [0001] The invention belongs to the technical field of marine exploration, and in particular relates to a seabed bubble generation simulation device. Background technique [0002] Natural gas hydrate is a new type of potential energy, and it is the best alternative clean energy after petroleum and natural gas. It is mainly distributed in seabed sediments and land permafrost. Under the action of crustal dynamics, natural gas hydrate migrates upwards inside the crust, passes through seabed sediments through migration channels such as voids, fissures or faults, and enters seawater in the form of seepage or gushing, forming a plume of seabed bubbles. Bubble plumes are often found in the overlying seawater in the region, and submarine bubble plumes are an important sign for identifying gas hydrates. Multi-beam depth sounders, shallow strata profilers, and side-scan sonars can all be used for detection. Hydrate gas leaking from the seabed in real environments ofte...
