Description
Technical Field
The utility model belongs to the technical field of submarine detection, and particularly relates to a floating type stern dragging device of a shallow stratum profiler.
Background
The prior art comprises the following steps:
the submarine shallow stratum profile detection is a geophysical method for continuously sailing to detect the structure and the structure of an underwater stratum based on an acoustic principle, and is widely applied to ocean engineering investigation due to high sensitivity and resolution, good continuity and capability of efficiently detecting the geological features and the distribution of the underwater stratum. A shallow profiler is a geophysical survey instrument system used to resolve different formations below the water bottom. The shallow profile instrument is generally composed of a shallow profile towed fish, a cable, a deck processor, and a notebook computer with software installed for corresponding shallow profile detection data collection. The shallow-section towed fish is actually a low-frequency sonar transducer, and can send proper detection sound waves according to the geological features of a detection area and receive echoes generated by submarine strata in real time. In the actual submarine exploration process, the exploration ship places shallow-profile towed fish below the sea surface for 0.5m, and the exploration ship uses towing cables to tow the sea surface in a sailing manner so as to acquire continuous submarine stratum information. After the shallow-section towed fish collects data below the water surface, data information is transmitted to a deck processor on the ship through a cable and used for acquiring submarine stratum detection data.
However, the inventor of the present application found that at least the following technical problems exist in the above prior art:
in open sea exploration operation, the facing sea conditions are often complex, and a larger exploration ship is needed to ensure exploration safety, but the larger exploration ship has large propulsion power and high jet flow velocity of a propeller, so that larger wake flow can be excited at the stern in the navigation process. When the high-speed ship passes around the detection ship, the surge in a certain range can be stimulated, and the underwater posture of the shallow-section towing fish which is being towed is influenced to a certain extent. Particularly, under the condition of high surge, the fluctuation of the waves can cause the transverse movement of the fish supporting body to obviously influence the data acquisition quality and reduce the detection precision.
In the existing data acquisition technology, environmental influence factors such as stern jet flow, wave fluctuation and the like have great influence on data acquisition quality, and the problems of easiness in producing serious consequences such as shallow-section fish stranding and damage exist. Meanwhile, the difficulty of solving the technical problems is as follows:
1. when the detection ship tail is towed to be towed by a shallow profile, the detection ship encounters an emergency, suddenly slows down or turns and is at a stranding risk. When the detection ship completes one straight line, the detection ship needs to turn around to enter the next course for detection, namely, 180-degree turning is performed, and in order to shorten the turning radius, the detection ship needs to slow down in advance in the turning process. In the speed-reducing turning process, the shallow profile towed fish towed by the tail of the detection boat loses the towing power of the original sailing direction, and the whole sinking can be caused under the influence of gravity. Because the end of the measuring line is often the boundary of the water area in the measuring area, the situation that the water depth is shallow may exist, and stranding is easy to occur. Similarly, in water to a shallow depth, shallow section of towed fish is also at risk of stranding, which can cause serious damage to the equipment.
2. Shallow profile dragees fish and drags in-process at the tail, and the income water depth receives the ship speed influence, can not fix a certain distance below the surface of water, influences data acquisition quality, reduces the detection precision.
3. The shallow-section towed fish is influenced by water flow in the tail towing process, the yaw amplitude is increased, the heading is difficult to fix, and the data acquisition quality is seriously influenced.
Difficulty and meaning for solving the technical problems:
therefore, based on the problems, the floating type stern dragging device of the shallow stratum profiler, which has the advantages of simple structure, convenience in use and reliability in performance, and can reduce the risk of stranding of the shallow profile dragging fish, fix the depth and reduce the yaw amplitude in the process of dragging the stern of the shallow profile dragging fish, has important practical value.
