Description

Technical Field

[0001] The invention relates to the technical field of marine engineering, and in particular to an anti-interference device for sampling seabed sediments which simulates the movement of bird wings. Background Art

[0002] Marine sediments refer to the general term for seabed sediments formed by various marine sedimentation processes. These marine sediments are usually collected for detection and analysis to observe whether natural gas, oil and other substances are distributed in this sea area. However, when collecting seabed sediments, the existing seabed sediment sampling device has a large fluidity of seawater and a large number of marine organisms on the seabed. It is difficult to ensure that there will be no stirring of seabed organisms during seabed sediment sampling, resulting in water quality changes, and the sediments under the seabed that need to be sampled are all stirred up and washed away by seawater, making the collected sample data inaccurate. Sampling can only be carried out after all the seabed sediments have settled. Summary of the invention

[0037] Detailed usage and function of this embodiment:

[0038] The device is placed in the sea area where sampling is required. When the entire device is descending, the seawater in the sea area will fill the fairness cup body 2 at both ends, causing the seawater to enter the water storage tank 4 through the diversion channel 3 after reaching a certain depth inside the fairness cup body 2, thereby increasing the weight of the device and accelerating the falling speed. At the same time, the seawater also fills the water storage tanks on both sides. In addition, when the device is descending in the seawater, the seawater will enter the reflux channel 13 along a number of diversion holes 14, thereby increasing the weight of the water-absorbing ball 9, allowing the entire device to descend faster and more steadily. When it lands on the seabed, the motor 16 electrically connected to the external controller is driven to drive the motor 16 to drive the gear 18 to rotate, and the gear 18 drives the meshing gear 2 19 below to rotate, so that the gear 2 19 drives the drive rod 35 connected to the side end to move during the rotation, and then the limit slider 27 connected to the lower end of the drive rod 35 moves up and down in the return groove of the return plate 26. When the limit slider 27 moves up and down, the movable plate 1 29 and the movable plate 2 30 at both ends are driven by the connecting shaft 1 28 to cause the covers 32 at both ends to expand and close under the limit of the limit pull rod 33. When the cover 32 covers the sampling part 7, the hydraulic rod 38 is driven. When the hydraulic rod 38 moves downward, the U-shaped bracket 39 is pushed downward. Since the limit rods 40 interlaced at both ends of the bottom of the U-shaped bracket 39 are located in the strip groove 44, when the U-shaped bracket 3 When the shell 1 moves downward, the limit rod 40 drives the clamping plate 41 to deform and expand the clamping plate 41. On the contrary, the two clamping plates 41 move closer together, so that the stones to be collected are clamped. Then, a controller (HAD-SC200 universal controller) is installed inside the shell 1 to drive the controller to move the entire device upward and retract the entire device to the sea surface. During the retraction process, the cover 32 always wraps the sampling part 7 to prevent seawater and marine organisms from hitting the claw 45 end.

However, it should be understood that the present invention is not limited to the above specific implementations. On the basis of the disclosed implementations, those skilled in the art can arbitrarily combine different technical features to achieve different technical solutions.
