Description

Technical Field

[0001] The utility model relates to the technical field of seabed sampling, in particular to a seabed sampling device. Background Art

[0002] The deep ocean is widely covered with a layer of mysterious but very valuable seabed sediments. Seabed sediments are of great significance for understanding the changes in the earth's environment, revealing the internal connections between the earth's environmental systems, and predicting future long-term climate changes. Sampling and in-depth research on seabed sediments can enable humans to obtain very important scientific value in the fields of marine science research, marine environment research, marine resource exploration, marine engineering exploration, etc., and have important strategic significance for humans to understand the earth and develop the ocean.

[0003] The existing Chinese patent with authorization announcement number (CN219625080U) discloses a marine seabed sampling device, including a sampling barrel and a protective cover. The protective cover is located above the sampling barrel, and the protective cover and the sampling barrel are integrally connected. A mounting seat is fixedly installed between the inner cavity of the protective cover and the top of the sampling barrel, and a transmission mechanism is provided above the mounting seat. The transmission mechanism passes through the top of the sampling barrel and is located in the inner cavity of the sampling barrel. The sampling barrel is fixedly equipped with two mutually symmetrical baffles, and two mutually symmetrical folding barrels are fixedly installed above the protective cover. This utility model starts the motor to enable the transmission mechanism to operate, so that it can drive the clamping plate to move and clamp stones, etc., and because the clamping plate is located in the sampling barrel, when it is taken out from the seabed, it will not be affected by the flow of seawater and fall. However, this utility model lacks a limiting mechanism at the bottom of the sampling barrel. During the process of pulling the sampling barrel upward from the seabed, the sampling barrel will be affected by the flow of seawater and shake. Once the sampling barrel shakes, the clamped sample is likely to fall.

[0004] In order to solve the above problems, we propose a seabed sampling device to solve the above problems. Utility Model Content

[0028] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows:

[0029] Example 1: Reference Figure 1-5As shown, a seabed sampling device of this embodiment includes a sampling box 1, a sampling cavity 2 is provided in the inner middle portion of the sampling box 1, and a clamping mechanism is provided in the inner middle portion of the sampling cavity 2;

[0030] The clamping mechanism includes two groups of clamping plates 3, which are respectively located at the inner ends of the sampling chamber 2. A transmission component is provided in the middle of the back side of the clamping plate 3, and the transmission component drives the clamping plate 3 to slide horizontally and vertically, thereby realizing the horizontal and vertical sliding of the positions of the two groups of clamping plates 3.

[0031] Among them, the transmission assembly includes a hydraulic rod 4, the output end of the hydraulic rod 4 is fixedly connected to the back of the clamping plate 3, and the clamping plate 3 is pushed by the hydraulic rod 4 to move horizontally. When the two groups of clamping plates 3 move toward the center point, the sample stone located between the two groups of clamping plates 3 is clamped and fixed at both ends.

[0032] The transmission assembly also includes a servo motor 13, which is fixedly mounted on the inner top of the sampling box 1. The output end of the servo motor 13 is connected to two sets of rotating shafts 12 through a gear box transmission, and a second bevel gear 11 is provided at the end of the rotating shaft 12; screw rods 9 are rotatably installed at both ends of the inner side of the sampling box 1, and a first bevel gear 10 is provided at the top of the screw rod 9. The first bevel gear 10 is meshed with the second bevel gear 11. A sliding block 5 is provided at the bottom of the hydraulic rod 4, and a threaded hole 6 is provided in the inner middle part of the sliding block 5. The screw rod 9 is threadedly installed in the inner middle part of the threaded hole 6.

[0033] Among them, the servo motor 13 drives the rotating shaft 12 to rotate, and then drives the screw 9 to rotate under the transmission of the first bevel gear 10 and the second bevel gear 11, so that the sliding block 5 drives the hydraulic rod 4 to move up and down, thereby realizing the vertical lifting and lowering adjustment of the positions of the two sets of clamping plates 3.

[0034] In addition, a limiting assembly is provided at the bottom end of the sliding block 5, including a limiting slide groove 7 and a guide rail 8. The guide rail 8 is fixedly installed at both ends of the inner side of the sampling box 1. The limiting slide groove 7 is slidably connected to the guide rail 8. The limiting slide groove 7 and the guide rail 8 stabilize the lifting and sliding of the sliding block 5, thereby avoiding the problem of tilting of the sliding block 5 during the lifting process due to uneven force.

[0035] In some examples, two sets of support columns 15 are fixedly mounted on the inner top of the sampling box 1, and the rotating shaft 12 is rotatably mounted on the inner middle portion of the support columns 15. The support columns 15 play a role in stably supporting the rotating shaft 12.

[0036] In some examples, a pull ring 14 is provided at the middle of the top end of the sampling box 1 .

[0037] In some examples, monitoring probes are provided around the inner side of the sampling cavity 2 , and the monitoring probes facilitate the staff to adjust the positions of the two sets of clamping plates 3 according to the objects to be sampled.

[0038] Example 2: Reference Figure 1-5 As shown, based on Example 1, a seabed sampling device further includes the following structure:

[0039] A supporting mechanism is provided at the middle of the bottom end of the sampling box 1;

[0040] The supporting mechanism includes two sets of supporting plates 16 and two sets of mounting seats 19. The two sets of mounting seats 19 are fixedly mounted on both sides of the bottom end of the sampling box 1, and the supporting plates 16 are slidably mounted on the inner middle part of the mounting seats 19.

[0041] A driving assembly is provided between the supporting plate 16 and the mounting seat 19. The driving assembly includes two sets of racks 17. The two sets of racks 17 are respectively provided on both sides of the bottom end of the supporting plate 16. A plurality of transmission gears 20 are provided at the inner bottom of the mounting seat 19. The plurality of transmission gears 20 are all driven by a motor. The transmission gears 20 are located in the middle of the bottom end of the rack 17 and are meshed with the rack 17.

[0042] Among them, the driving component is used to drive the support plate 16 to slide horizontally. When the two groups of support plates 16 slide outward, the bottom of the sampling chamber 2 is in an open state, which makes it convenient to cover the sample stone from top to bottom with the sampling box 1. When the two groups of support plates 16 slide inward until they touch, the bottom opening of the sampling chamber 2 is closed.

[0043] In some examples, a plurality of groups of water leakage holes 18 are provided in the inner middle portion of the support plate 16. The plurality of water leakage holes 18 are distributed in an array, which facilitates the lifting of the sampling box 1, plays a role in leaking water, avoids the accumulation of seawater in the sampling cavity 2, and increases the gravity when the sampling box 1 is lifted.

[0044] The working principle of this utility model is:

[0045] When it is necessary to sample the seabed sample stone, first move the sampling box 1 to the position above the sample, then start the drive assembly, and use the motor to drive multiple sets of transmission gears 20 to rotate forward, so that the support plate 16 slides horizontally to the outside, so as to facilitate the sampling box 1 to cover the sample stone from top to bottom. After the sampling box 1 covers the stone to be sampled, it can resist the seawater, preventing the sample stone from shaking due to the flow of seawater, affecting the clamping and fixing of the sample stone by the clamping plate 3.

[0046] At this time, the staff observes the situation inside the sampling box 1 through the monitoring probe, so that the staff can start the transmission component to adjust the position of the two sets of clamping plates 3 horizontally and vertically, so that the two sets of clamping plates 3 can clamp and fix the sample stone from the middle of both ends of the sample stone;

[0047] After the two sets of clamping plates 3 clamp the sample stone at both ends, the sliding block 5 is driven by the transmission assembly to slide upward, so that the sample stone rises and separates from the seabed;

[0048] Then, the driving assembly is started, and the motor drives the multiple sets of transmission gears 20 to rotate in the opposite direction. Under the rotation of the multiple sets of transmission gears 20, the rack 17 drives the support plate 16 to slide horizontally inward. When the two sets of support plates 16 slide inward and contact, the bottom port of the sampling chamber 2 is closed.

[0049] At this time, the transmission component is used to drive the sliding block 5 to descend, so that the sampling stone falls on the upper surface of the two sets of support plates 16 and is placed there, thereby improving the stability of the sample stone when it is clamped and fixed. When the sampling box 1 is pulled up, even if it is shaken by the flow of seawater, the clamped sample stone can still be stably placed on the two sets of support plates 16, which effectively solves the problem of the sample stone falling off due to the shaking of the sampling box 1.

[0050] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
