Description

Technical Field

[0001] This utility model belongs to the technical field of box-type samplers, specifically relating to a highly stable deep-sea box-type sampler. Background Technology

[0002] The deep-sea box sampler is a sampling device specifically designed for deep-sea environments. Its main body is made of high-strength, pressure-resistant material, and the bottom is equipped with a sharp sampling shovel. When it sinks to the seabed, it can use its own weight or mechanical force to cut into the surface of sediments, forming a closed space to collect samples. The sealing system on the top of the box can automatically close after sampling to prevent the samples from being damaged by water pressure changes or seawater erosion during the recovery process. At the same time, the counterweight and control system ensures its smooth sinking and precise operation, which can preserve the original stratification structure and state of deep-sea sediments and overlying water samples to the greatest extent, providing real and reliable samples for scientific research in marine geology, biology, chemistry and other fields.

[0003] Chinese Patent Publication No. CN218973886U discloses a deep-sea box-type sampler. Although it can reduce the landing pressure of the box-type sampler body through shock-absorbing components, the shock-absorbing components of the existing device mainly buffer and reduce pressure through springs and friction at the connection of parts, so its shock-absorbing performance is not high. In addition, the entire shock-absorbing component of the existing device is completely exposed to the outside, so it will be in contact with seawater for a long time during use, and the surface of its parts is very prone to corrosion, thereby reducing the service life of the existing device.

[0015] The present invention will be further described below with reference to the embodiments.

[0016] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention.

[0017] Please see Figure 1-5This utility model provides a highly stable deep-sea box sampler, including a deep-sea box sampler body 1. Fixing blocks 2 are fixedly connected to the front and rear sides of the deep-sea box sampler body 1. A support frame 3 is provided on the top of the fixing blocks 2. Support legs 4 are fixedly connected to the left and right sides of the deep-sea box sampler body 1. A shock-absorbing assembly is provided inside the support legs 4. The shock-absorbing assembly includes a shock-absorbing cavity 401, a support rod 402, a threaded spring 406, a spring shock absorber 407, a bellows 408, and a vent 409. The shock-absorbing cavity 401 is located at the bottom of the support legs 4. The support rod 402 is sealed and fitted inside the shock-absorbing cavity 401. Two symmetrically arranged supports are located on the upper part of the shock-absorbing cavity 401. A connecting shaft 403 is connected to the support rod 402. Two connecting shafts 404 are symmetrically arranged on the top of the support rod 402. The two connecting shafts 403 and the two connecting shafts 404 correspond one-to-one. A connecting rod 405 is hinged between the connecting shaft 403 and the corresponding connecting shaft 404. A threaded spring 406 is fixedly connected to the top of the support rod 402 and located between the connecting shafts 404. A spring shock absorber 407 is fixedly connected to the top of the support rod 402 and located on the side of the connecting shaft 404. A bellows 408 is fixedly sleeved on the outside of the support rod 402 and its two ends are respectively sealed to the support leg 4 and the support rod 402. A vent 409 is opened on the top of the support rod 402.

[0018] The deep-sea box sampler body 1 serves as the core load-bearing structure, used to load samples collected from the deep sea. The fixing blocks 2 on the front and rear sides cooperate with the support frame 3 on the top to facilitate the connection and fixation of the equipment with external hoisting equipment. The support legs 4 on the left and right sides cooperate with the internal shock-absorbing components. When the deep-sea box sampler body 1 is placed, the shock-absorbing cavity 401, support rod 402, connecting shaft one 403, connecting shaft two 404, connecting rod 405, threaded spring 406, and spring shock absorber 407 work together to effectively absorb the vibration and impact from the placement surface through the elastic deformation of the spring and the buffering effect of the linkage mechanism. The corrugated structure of the bellows 408 undergoes axial expansion and contraction when the support rod 402 moves up and down. At the same time, it undergoes radial elastic deformation due to changes in air pressure inside the shock-absorbing cavity 401, further absorbing vibration energy. The combination of the bellows 408 and the vent 409 can not only prevent dust and water, but also balance the air pressure inside the shock-absorbing cavity 401, avoiding the impact of air pressure changes on performance during shock absorption. This improves the stability and impact resistance of the deep-sea box sampler body 1 when it is placed.

[0019] The shock absorption assembly of this utility model, through the dual shock absorption structure composed of a threaded spring 406 and a spring shock absorber 407, can effectively buffer the impact between the deep-sea box sampler body 1 and the placement surface, greatly improving the stability and reliability of the deep-sea box sampler body 1 during placement, preventing damage and spillage of samples inside the deep-sea box sampler body 1, and ensuring the integrity of the collection; the corrugated pipe 408, which is fitted on the outside of the support rod 402, has a sealing design that can resist seawater and silt erosion, extending the service life of the components inside the shock absorption cavity 401. In addition, the vent 409 opened at the top of the support rod 402 balances the air pressure, ensuring the stable operation of the shock absorption assembly in various environments and significantly extending the service life of the equipment.

[0020] Specifically, such as Figure 1 , Figure 4 and Figure 5 As shown, the bottom of the support frame 3 is symmetrically connected with connecting blocks 301. The connecting blocks 301 have internal fixing holes 302. The fixing blocks 2 have internal fixing components, including connecting holes 201, limiting grooves 202, threaded rods 203, knobs 204, and pins 205. The connecting blocks 301 and fixing holes 302 at the bottom of the support frame 3, as well as the fixing components inside the fixing blocks 2, provide multiple options and reliable fixing methods for connecting the sampler to external equipment. The connecting holes 201 cooperate with the connecting blocks 301, allowing the support frame 3 to be securely installed on the fixing blocks 2. The limiting grooves 202, threaded rods 203, knobs 204, and pins 205 in the fixing components work together. By rotating the threaded rods 203 through the knobs 204, the pins 205 move within the limiting grooves 202, locking or unlocking the connecting blocks 301. This facilitates installation and disassembly, enhances the flexibility and stability of the sampler's connection to external equipment, and makes it suitable for use in different operating scenarios.

[0021] The fixing component of this utility model, through the self-locking characteristic of the threaded rod 203, ensures that the support frame 3 and the fixing block 2 are firmly connected and do not loosen in the high-pressure environment of the deep sea, providing a safety guarantee for sampling operations; the U-shaped pin 205 is adapted to the fixing hole 302 on the connecting block 301, reducing the difficulty of operation and facilitating quick installation; the external knob 204 design does not require professional tools and can be easily operated manually, significantly improving installation and maintenance efficiency, and is suitable for diverse deep-sea operation scenarios.

[0022] The connecting holes 201 are symmetrically distributed inside the fixed block 2. The limiting groove 202 is opened on the inner wall of the connecting hole 201. The threaded rod 203 is rotatably connected inside the limiting groove 202. The knob 204 is rotatably connected to the outside of the fixed block 2 and is fixedly connected to the threaded rod 203. The pin 205 is slidably connected inside the limiting groove 202 and is threadedly connected to the threaded rod 203.

[0023] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, a support pad 5 is fixedly connected to the bottom of the support rod 402, and an anti-slip protrusion 6 is fixedly connected to the bottom of the support pad 5. A connecting ring 7 is fixedly connected to the top of the support frame 3. The support pad 5 at the bottom of the support rod 402 increases the contact area with the placement surface, reducing the pressure of the deep-sea box sampler body 1 on the placement surface; the anti-slip protrusion 6 at the bottom of the support pad 5 increases the friction with the placement surface, making the deep-sea box sampler body 1 more stable and less prone to slipping during placement; the connecting ring 7 at the top of the support frame 3 facilitates the connection of the hook or rope of the hoisting equipment, facilitating the deployment and retrieval of the deep-sea box sampler body 1, which improves operational convenience and ensures operational safety, guaranteeing the smooth progress of sampling operations.

[0024] Specifically, such as Figure 2 As shown, the ends of the threaded spring 406 and the spring damper 407 furthest from the support rod 402 are fixedly connected to the top of the damping cavity 401. The damping cavity 401 is connected to the bellows 408 through the vent hole 409. The bellows 408 is made of metal-rubber composite material. The connecting rod 405 connects the first connecting shaft 403 and the second connecting shaft 404, playing a role in force transmission and structural support during the damping process, thus stabilizing the damping structure. The threaded spring 406 and the spring damper 407 absorb vibration energy through elastic deformation, reducing the impact of vibration on the sampler body. The bellows 408 seals and wraps the support rod 402, preventing seawater, silt, etc. from entering the damping cavity 401 and protecting the internal damping components. The damping cavity 401 is connected to the inside of the bellows 408 through the vent hole 409, balancing the air pressure and ensuring the normal operation of the damping components, effectively improving the damping performance and service life of the sampler.

[0025] The connecting hole 201 is shaped to match the connecting block 301. The pin 205 is U-shaped, and the U-shaped opening of the pin 205 is shaped to match the fixing hole 302. The pin 205 is also shaped to match the limiting slide groove 202. The matching shape of the connecting hole 201 and the connecting block 301 ensures that they fit tightly together for precise positioning. The U-shaped pin 205 is shaped to match the fixing hole 302, allowing it to be fully inserted into the fixing hole 302 and providing reliable locking force. The matching shape of the pin 205 and the limiting slide groove 202 ensures that the pin 205 slides stably within the limiting slide groove 202 without shifting or jamming.

[0026] Working principle and usage process of this utility model: When the deep-sea box sampler body 1 is placed on the placement surface, the support rod 402 at the bottom of the support leg 4 is impacted by the placement surface and compressed upward along the inner wall of the shock-absorbing cavity 401, causing the connecting shaft 2 404 to move upward synchronously. The impact force is transmitted to the connecting shaft 1 403 through the connecting rod 405, causing the threaded spring 406 located between the connecting shafts 2 404 and the spring shock absorber 407 on the side to compress and deform. The elastic deformation absorbs a large amount of vibration energy, reducing the impact of vibration on the deep-sea box sampler body 1 and the sample. At the same time, the bellows 408 sleeved on the outside of the support rod 402 is compressed, and the vent hole 409 at the top of the support rod 402 allows air inside the shock-absorbing cavity 401 to be discharged into the bellows 408, causing the bellows 408 to expand. This regulates the internal air pressure, preventing the shock-absorbing components from operating normally due to air pressure differences, and ensuring the stable performance of the multi-stage shock absorption effect.

[0027] When installing and disassembling the support frame 3, align the connecting block 301 at the bottom of the support frame 3 with and insert it into the connecting hole 201 of the fixing block 2 to complete the initial positioning. Then, the operator manually rotates the knob 204 on the outside of the fixing block 2. The knob 204 drives the threaded rod 203, which is fixedly connected to it, to rotate in the limiting slide groove 202. Since the pin 205 is threadedly connected to the threaded rod 203 and its shape is adapted to the limiting slide groove 202, when the threaded rod 203 rotates, the pin 205 slides linearly along the track of the limiting slide groove 202 and gradually inserts into the fixing hole 302 of the connecting block 301. By utilizing the self-locking characteristic of the threaded drive combined with the limiting effect of the pin 205, the support frame 3 and the fixing block 2 are tightly locked. When disassembling, rotate the knob 204 in the opposite direction to make the pin 205 exit from the fixing hole 302, and the two can be separated.
