Description

Quick collector for bottom mud on surface layer of shallow water body

Technical Field

The utility model belongs to water top layer sediment sampling device, specifically speaking especially relates to a quick collector of shallow water top layer sediment.

Background

The sediment is usually a mixture of clay, silt, organic matters and various minerals deposited on the bottom of the water body through long-term physical, chemical and biological actions and water body transmission. The surface layer sediment refers to sediment with the thickness ranging from 0cm to 15cm away from the surface of the sediment. The sediment is an important link for researching biogeochemical circulation of elements such as carbon, nitrogen, sulfur and the like in a water ecosystem and water pollution, the collection of sediment samples in a water body is work with strong technical requirements, and the performance of a mud sampler has important influence on the quality and efficiency of sample collection in the sediment sampling process.

At present, surface sediment sampling mainly comprises a grabbing type collecting device and a drilling type collecting device. Snatch formula collection system mainly utilizes self gravity to make its part sink in the sediment sample, and collection system need 2~3 people's cooperations in very the cup just can accomplish the sampling operation, and the sampling operation is complicated, hard, uncontrollable sampling depth, collection inefficiency. And the grabbing type collecting device has larger disturbance to the sediment in the sampling operation process, and destroys the initial form of the sediment.

Drilling sampling devices currently exist in both gravity and vibration modes. The sampler is got to gravity type brill is a sampling device of present widely used, and it relies on sample thief and balancing weight self gravity to sink in the mud and samples, but most bulky, the weight of this kind of sample thief is big, and physical demands is too big and can't independently accomplish the sampling operation when operating personnel uses, is not suitable for the operation of small-size ship. The vibrating drilling mud sampler mainly realizes sampling by oil movement and electric modes, has the problems of upward gravity center, large disturbance to bottom mud, high cost and the like generally, and also has the problems of easiness in environmental limitation, no guarantee of power supply of a storage battery, poor stability and the like. No matter the gravity type drilling sampler or the drilling sampler during vibration, the volume and the weight are large, the operation is complex, the cooperation of multiple persons is needed, the sampling efficiency is low, and the small-scale research sampling is not facilitated.

At present, some portable mud collecting devices suitable for shallow water bodies appear on the market. If the sediment collecting device (CN 106989954A) is suitable for the rice and fishing interaction system, the sediment in rice with the effective planting depth of 12-15 cm can be accurately collected, and the operation is simple and rapid. The hand-held columnar sediment collector (CN 106969937A) with the mud cutting edge can collect hard columnar sediment samples, is simple and convenient to operate and is convenient to carry. For example, the undisturbed columnar sediment collector (CN 106124240A) comprises five parts, namely 10 components, and can be used for obtaining sediment samples with different depths and measuring the sampling depth and the water temperature. The portable devices have the characteristics of portability, simple operation, good reliability and the like, are mostly suitable for specific sediment types, have no strict requirement on the duration of sampling time, but have low adaptability.

In order to overcome the defects of heaviness, complex operation, low sampling efficiency and poor adaptability of the portable mud sampling device in the traditional mud sampling device in the prior art, the quick shallow water surface layer sediment collecting device with few components, simple operation, labor saving, high sampling speed, high efficiency, low cost and wide adaptability is provided.
