Description

Technical Field

[0001] This utility model relates to the field of marine exploration technology, and in particular to a marine exploration sampling device. Background Technology

[0002] With the deepening of marine scientific research, the demand for seabed sediment and sediment samples is increasing. These samples are of great significance for understanding marine geological structures, assessing seabed resource potential, and monitoring changes in the marine environment. However, in practice, due to the diversity of seabed sediments and sediments, efficiently and accurately acquiring and distinguishing different types of samples has become a challenge.

[0003] Traditional marine sampling methods typically rely on simple grabs or column samplers. While these tools can accomplish basic sampling tasks, they exhibit significant limitations when dealing with complex and varied seabed topography. For example, they struggle to effectively separate large sediment masses from fine particles, resulting in highly mixed samples that are detrimental to subsequent analysis. In recent years, although some new automated sampling equipment has emerged, most of them focus on improving the speed and accuracy of the sampling process, neglecting the natural stratification characteristics of the samples.

[0004] To address the aforementioned issues, we propose a marine exploration sampling device that can automatically separate large sediments and seabed silt after sampling, helping researchers obtain the required samples more accurately. Utility Model Content

[0005] To overcome the shortcomings of existing sampling devices that are unable to effectively separate large sediments from fine particles, resulting in high mixing of the collected samples and hindering subsequent analysis, this invention provides a marine exploration sampling device. This device can automatically separate large sediments from seabed sediments after sampling, helping researchers obtain the required samples more accurately.

[0006] The technical solution of this utility model is as follows: a marine exploration and sampling device, including a mounting frame, an electric winding wheel fixedly connected to the top of the mounting frame, a steel wire rope wound on the electric winding wheel, a guide wheel rotatably connected to the top of the mounting frame, the tail end of the steel wire rope passing over the guide wheel, a sampling bucket fixedly connected to the tail end of the steel wire rope, a side plate rotatably connected to the sampling bucket, a locking rod slidably connected to the sampling bucket, the locking rod locking the side plate, two symmetrical grab plates rotatably connected to the bottom of the sampling bucket, an electric push rod embedded and fixedly connected to the top of the sampling bucket, a lifting frame fixedly connected to the telescopic end of the electric push rod, a slide rail provided on the grab plate, the bottom end of the lifting frame slidably connected to the slide rail, separation components for separating large sediments and seabed mud and sand provided on the sampling bucket and the lifting frame, and a guide component for preventing the steel wire rope from swaying on the mounting frame.

[0007] As a preferred technical solution of this utility model, the sampling bucket has equally spaced filter holes.

[0008] As a preferred technical solution of this utility model, the grab plate is cone-shaped so as to grab into the seabed.

[0009] As a preferred technical solution of this utility model, the separation component includes two horizontally symmetrical limiting plates, which are fixedly connected to the lifting frame. Two longitudinally symmetrical partition frames are rotatably connected inside the sampling hopper. The limiting plates contact the partition frames and support and limit the partition frames.

[0010] As a preferred technical solution of this utility model, the side of the limiting plate that contacts the partition frame is provided with an inclined surface, which facilitates the limiting plate to squeeze the partition frame to rotate.

[0011] As a preferred technical solution of this utility model, the guide component includes two longitudinally symmetrical fixed frames, which are fixedly connected to the mounting frame. Two vertically symmetrical limit wheels are fixedly connected to the fixed frames, and the two longitudinally corresponding limit wheels cooperate with each other to limit the wire rope.

[0012] Beneficial effects: The electric reel releases the wire rope, and under the influence of gravity, the sampling bucket and grab plate move downwards and sink to the seabed. Because the lower end of the grab plate is conical, it can better penetrate the seabed. By controlling the extension and retraction of the electric push rod, the grab plate can be rotated outwards and inwards, thereby grabbing the sediment and silt from the seabed into the sampling bucket. When the separator rotates upwards, it can push the large sediments from the upper layer into the upper part of the sampling bucket, while the silt will leak into the lower part of the sampling bucket and between the two grab plates. In this way, large sediments and seabed silt can be automatically separated after sampling, helping researchers to obtain the required samples more accurately. Attached Figure Description

Detailed Implementation

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0022] Example 1: A marine exploration and sampling device, such as Figures 1-7 As shown, the assembly includes a mounting frame 1, an electric winding wheel 2, a wire rope 3, a guide wheel 4, a sampling hopper 5, a side plate 51, a locking rod 52, a gripping plate 6, an electric push rod 7, a lifting frame 8, a separation assembly, and a guide assembly. The electric winding wheel 2 is fixedly connected to the upper side of the mounting frame 1, and the wire rope 3 is wound on the electric winding wheel 2. The guide wheel 4 is rotatably connected to the upper side of the mounting frame 1, and the end of the wire rope 3 passes over the guide wheel 4. The end of the wire rope 3 is fixedly connected to the sampling hopper 5, which has equidistantly distributed filter holes. The side plate 51 is rotatably connected to the rear side of the sampling hopper 5. A sliding locking rod 52 is attached to the side plate 51. Two symmetrical grab plates 6 are rotatably connected to the lower side of the sampling bucket 5. The lower end of the grab plate 6 is conical to grab the seabed. An electric push rod 7 is embedded and fixedly connected to the upper part of the sampling bucket 5. The telescopic end of the electric push rod 7 is fixedly connected to the lifting frame 8. A slide rail is provided on the inner side of the grab plate 6. The lower part of the lifting frame 8 is slidably connected to the slide rail. Separation components for separating large sediments and seabed mud and sand are provided on the sampling bucket 5 and the lifting frame 8. A guide component for preventing the steel wire rope 3 from swaying is provided on the mounting frame 1.

[0023] When using the device, the operator mounts the mounting frame 1 onto the vessel used for marine exploration. Once the vessel reaches the designated position, the operator controls the electric reel 2 to rotate, releasing the wire rope 3. The guide wheel 4 guides the wire rope 3, while the guide assembly limits its movement, preventing the sampling bucket 5 from swaying. Under gravity, the sampling bucket 5 and the grab plate 6 move downwards and sink to the seabed. During this downward movement, the operator controls the electric push rod 7 to extend, causing the lifting frame 8 to move downwards. This downward movement of the lifting frame 8 opens the separation assembly and also pushes the grab plate 6 to rotate outwards and open. When the grab plate 6 reaches the seabed, its conical lower end allows for better insertion into the seabed. The staff controls the electric push rod 7 to shorten, which drives the lifting frame 8 to move upward. The upward movement of the lifting frame 8 causes the grab plate 6 to rotate inward and close. When the grab plate 6 rotates inward and closes, it can grab the sediment and silt from the sea into the sampling bucket 5. When the lifting frame 8 moves upward, it also controls the separation component to close. When the separation component closes, it can separate the large sediments in the upper part of the sampling bucket 5, while the silt stays in the lower part of the sampling bucket 5 and between the two grab plates 6. After sampling is completed, the staff controls the electric winding wheel 2 to reverse and wind up the wire rope 3. The wire rope 3 then drives the sampling bucket 5 and the grab plate 6 to move upward. Excess seawater in the sampling bucket 5 can be discharged through the filter hole. Then the staff opens the side plate 51 to remove the large sediments. The extension and retraction of the electric push rod 7 controls the grab plate 6 to open and discharge the bottom silt.

[0024] Example 2: Based on Example 1, such as Figure 6 As shown, the separation assembly includes a limiting plate 9 and a separator 10. The lower part of the lifting frame 8 is fixedly connected to two symmetrical limiting plates 9. The lower part of the sampling hopper 5 is rotatably connected to two symmetrical separators 10. The limiting plate 9 contacts the separator 10 and supports and limits the separator 10. The side of the limiting plate 9 that contacts the separator 10 is provided with an inclined surface, which makes it easy for the limiting plate 9 to squeeze the separator 10 to rotate upward.

[0025] When using this device, the downward movement of the lifting frame 8 will cause the limiting plate 9 to move downward. After the limiting plate 9 moves downward, it will no longer press against the separator 10, and the separator 10 will rotate downward and open. When the grab plate 6 grabs the sample into the sampling hopper 5, the upward movement of the lifting frame 8 will also cause the limiting plate 9 to move upward. The upward movement of the limiting plate 9 will squeeze the separator 10 to rotate upward. When the separator 10 rotates upward, it can push the large sediments in the upper layer into the upper part of the sampling hopper 5, while the mud and sand will leak into the lower part of the sampling hopper 5 and between the two grab plates 6.

[0026] like Figure 1 and Figure 7As shown, the guide assembly includes a fixed frame 11 and a limiting wheel 12. The upper right part of the mounting frame 1 is fixedly connected to two symmetrical fixed frames 11. The upper and lower parts of the fixed frame 11 are fixedly connected to the limiting wheel 12. The two corresponding limiting wheels 12 cooperate with each other to limit the wire rope 3.

[0027] When the wire rope 3 moves up and down, the upper and lower sets of limit wheels 12 can limit and guide the wire rope 3, reduce the swaying amplitude of the wire rope 3, and thus prevent the sampling bucket 5 from shaking.

[0028] Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by means of equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
