本发明涉及海洋沉积物取样领域，具体涉及一种新型无扰动海洋沉积物取样刀头。The invention relates to the field of marine sediment sampling, and in particular to a new type of undisturbed marine sediment sampling cutter head.
现有的海洋柱状沉积物取样器的取样刀头大多采用弹簧花瓣式刀头，在触底前花瓣始终处于闭合状态，在沉积物挤压下才能把花瓣冲开，不仅对沉积物进样产生阻力，降低了进样率，减小了取样长度，同时还对沉积物产生很大的扰动，破坏沉积物样品原始沉积层序和微结构，影响采样质量及后续样品的分析。Most of the sampling heads of existing marine columnar sediment samplers use spring petal-type cutter heads. The petals are always closed before hitting the bottom. The petals can only be opened under the squeeze of the sediment, which not only causes sediment sampling The resistance reduces the sampling rate and sampling length, and also causes great disturbance to the sediments, destroys the original sedimentary sequence and microstructure of the sediment samples, and affects the sampling quality and subsequent sample analysis.

本发明与现有技术相比，其有益效果在于：在取样器向下运动时，利用水流、沉积物对翻转杠杆向上的力卡住花瓣，保持花瓣在整个取样过程始终是张开的状态，在取样器取样完成开始往上提的时候，利用沉积物对翻转杠杆有向下的作用力，以翻转杠杆的轴承为支点，撬动花瓣，使花瓣闭合。因此刀头利用水流、沉积物等产生的天然阻力，通过翻转杠杆和花瓣的联动，保证整个取样过程花瓣始终是张开状态且紧贴内壁，能够有效解决弹性花瓣对沉积物进样产生扰动和阻力的问题，在提刀时借助沉积阻力及翻转杠杆的作用可以保证花瓣能及时关闭，在有效封堵沉积物样品泄漏的同时，提高取样效率、减少花瓣对沉积物的扰动，提高采样质量。Compared with the prior art, the beneficial effect of the present invention is that when the sampler moves downward, the upward force of the water flow and sediment on the flip lever is used to jam the petals, keeping the petals open throughout the entire sampling process. When the sampler completes the sampling and starts to lift up, the sediment is used to exert a downward force on the flip lever, and the bearing of the flip lever is used as the fulcrum to pry the petals to close them. Therefore, the cutter head makes use of the natural resistance generated by water flow, sediment, etc., and through the linkage of the flipping lever and the petals, it ensures that the petals are always open and close to the inner wall during the entire sampling process, which can effectively solve the problem of disturbance and interference caused by the elastic petals on sediment sampling. Regarding the resistance problem, the sedimentation resistance and the flip lever can be used to ensure that the petals can be closed in time when lifting the knife. While effectively blocking the leakage of sediment samples, it can also improve the sampling efficiency, reduce the disturbance of the petals to the sediment, and improve the sampling quality.

本实施例中，在取样器向下运动时，利用水流、沉积物对翻转杠杆组件3向上的力卡住花瓣，保持花瓣在整个取样过程始终是张开的状态，在取样器取样完成开始往上提的时候，利用沉积物对翻转杠杆组件3有向下的作用力，以翻转杠杆组件3的轴承为支点，撬动花瓣，使花瓣闭合。因此，刀头利用水流、沉积物等产生的天然阻力，通过翻转杠杆组件3和花瓣组件的联动，保证整个取样过程花瓣始终是张开状态且紧贴内壁，能够有效解决弹性花瓣对沉积物进样产生扰动和阻力的问题，在提刀时借助沉积阻力及翻转杠杆组件3的作用可以保证花瓣能及时关闭，在有效封堵沉积物样品泄漏的同时，提高取样效率、减少花瓣对沉积物的扰动，提高采样质量。In this embodiment, when the sampler moves downward, the upward force of water flow and sediment on the flip lever assembly 3 is used to block the petals, keeping the petals open throughout the entire sampling process. When lifting, the sediment is used to exert a downward force on the flip lever assembly 3, and the bearing of the flip lever assembly 3 is used as a fulcrum to pry the petals to close them. Therefore, the cutter head makes use of the natural resistance generated by water flow, sediment, etc., and through the linkage of the flip lever assembly 3 and the petal assembly, it ensures that the petals are always open and close to the inner wall during the entire sampling process, which can effectively solve the problem of the impact of elastic petals on sediments. The problem of disturbance and resistance caused by this method can be ensured by using the deposited resistance and the action of the flip lever assembly 3 when lifting the knife. It ensures that the petals can be closed in time, effectively blocking the leakage of sediment samples, while improving the sampling efficiency, reducing the disturbance of the petals to the sediment, and improving the sampling quality.
