Description

Columnar sediment collecting device

Technical Field

The utility model belongs to the technical field of ecological environment, especially, relate to a column deposit collection system.

Background

The sediments are used as important components of aquatic ecosystems such as oceans, reservoirs and the like, are main sources of nutrients required by aquatic plant growth, and are important places for inhabitation and multiplication of aquatic organism communities. The sediment-water interface is an environment boundary formed by two phases of water and sediment, and the sediment particle density, particle composition, chemical substance activity, pH, dissolved oxygen, oxidation-reduction potential, biological activity and the like in the interface have obvious gradient changes and are environment boundaries with most obvious differences in the aspects of physical, chemical, biological characteristics and the like of an aquatic ecosystem; the physical and chemical reactions taking place in the interface under the participation of organisms, including oxidation and reduction, dissolution and precipitation, adsorption and desorption, migration and transformation, diffusion and burial, bacterial biochemical reactions, biological disturbance and the like, are important aspects of the geochemical cycle and biological system coupling of the water environment, and are important ways for controlling and regulating the material transmission and exchange between water and sediments. Obtaining surface sediment samples with in-situ fidelity is particularly critical to the in-depth revealing of the geochemical cycle behavior of the sediment-water interface.

The existing underwater sediment sampling devices are many, and the sampling devices can be directly used for sampling by adopting pipes in intertidal zones or shallow water areas. The deeper regions are generally collected by gravity or electric methods; the gravity method is that weights such as lead blocks are hung outside the sampling pipe, and the sampling pipe is hammered into mud by using the weight of the weights; the electric method is to use the motor on the external sampling pipe to vibrate continuously to insert the sampling pipe into the sediment gradually. In order to prevent the sample in the sampling tube from sliding off, the bottom of the sampling tube is generally provided with plum petals which can prevent mud from falling off. But the gravity method has the defects of high cost of used equipment, heavy weight of lead blocks and inconvenience in carrying and operation; the disadvantage of the electric method is that the equipment cost is high, the power supply is needed, and the general unit is rarely configured. In addition, the plum petals at the bottom of the sampling tube are fixed on the inner wall of the sampling tube, and metal sheets of the plum petals can extrude and disturb a sediment sample entering the sampling tube, so that the real position of the sample is changed, and the upper sample can be brought to the lower part, so that the samples at different layers are polluted.
