Description

Technical Field

[0001] The invention relates to a suspended sand current comprehensive collection device, in particular to a self-contained ocean near-bottom suspended sand current synchronous comprehensive collection device. Background Art

[0002] During the planning, site selection, operation and maintenance stages of coastal ports, the problem of sediment siltation in the waterway is one of the most concerned issues and difficulties for construction units and scientific research and design units. The conventional sediment siltation problem in China is mainly solved by comprehensive technical means such as sediment mathematical models, sediment physical models and on-site prototype observations, and the current technology is relatively mature. However, under normal weather conditions, the waterways of most seaports usually do not produce too much siltation. However, under severe weather conditions such as typhoons and cold waves, under the action of hydrodynamic forces such as wave sand lifting and tidal sand transport, it may bring a large amount of siltation. In particular, the superposition of other factors that are conducive to sediment transport and siltation often causes sudden siltation in the waterway, thereby affecting navigation. Once the waterway siltation occurs, it not only greatly reduces the navigation efficiency of the port, but also greatly increases the dredging cost of the waterway. Therefore, it is particularly important to scientifically study the sediment siltation problem of the port, especially to study the sediment siltation problem under severe weather conditions, and then provide scientific siltation reduction solutions for the line selection design of the waterway and the optimization design of the breakwater.

[0003] The on-site sediment prototype observation technology under normal weather conditions is relatively mature at present, and can provide relatively accurate measured data for the verification of sediment mathematical models and physical models. However, on-site sediment observation and related wave and current observation during severe weather are quite difficult, mainly manifested in the fact that the observation instruments are easily lost or damaged, the observation position is not easy to fix and stabilize, the observation data is incomplete, and the quality and accuracy of the observation data are not high. Moreover, for a specific port, the probability of severe weather, especially extreme weather such as typhoons, is relatively low. Once the observation opportunity of a severe weather process is missed, it is often necessary to wait for a long time, thus delaying the construction period of the entire project and causing great losses to the construction unit.

[0004] At present, all kinds of sediment and ocean current observation instruments are relatively advanced and mature. The main reason for the problems in field observations is that the design of the observation device is not mature and reasonable. In particular, there is no mature and reliable device to cooperate with the instrument for continuous and reliable observation and sampling for the observation needs during extreme weather periods such as typhoons. In response to this well-known technical problem, some people have designed a tripod to place ADCP and turbidity meters for observing bottom flow and stratified sediment content, designed a sediment enrichment device to collect suspended sand samples, or simply physically merged the two for synchronous observation, which has initially solved this problem; but because the overall idea of ​​the design is independent design and simple merging, coupled with shortcomings such as lack of safety, it has certain limitations in use. In this context, it is particularly important to design a scientific and reasonable integrated collection device that integrates flow measurement and sand sampling. Summary of the invention

[0005] In order to solve the technical problems existing in the known technology, the present invention provides a self-contained ocean near-bottom suspended sand current synchronous comprehensive collection device.
