Description

Technical Field

[0001] The utility model relates to a bottom-mounted observation bracket, in particular to a portable integrated stainless steel bottom-mounted wave-current-sediment comprehensive observation bracket. Background Art

[0002] The muddy coast is mainly located near some large river estuaries and is distributed in many countries around the world. The muddy coast in China accounts for a quite large proportion, about one-fourth of the continental coastline, including the estuaries of the Haihe River, the Yangtze River, the Pearl River, etc., and is distributed from north to south. The characteristics of the muddy coast are: the coastline is straight, the slope of the beach is extremely gentle, and the intertidal flat between the high tide level and the low tide level is broad. The muddy coast is mainly composed of extremely fine sediment particles, which are also called cohesive sediment. Its characteristic is that it is easily stirred and suspended by dynamic factors such as waves and tides, often causing the siltation of ports and waterways and the erosion and deposition changes of the beach. In addition, pollutants in seawater are particularly easy to adsorb on the cohesive fine-grained sediment, and the movement of the fine-grained sediment is often closely related to the migration of pollutants. Therefore, when studying practical engineering problems such as the protection of the muddy coast, the maintenance of the water depth of ports and waterways, and the regulation of river estuaries, as well as the coastal and estuarine environmental problems, it is necessary to focus on the movement of cohesive fine-grained sediment.

[0003] To study the movement of cohesive fine-grained sediment, technical means such as sediment mathematical models, sediment physical models, and on-site prototype observations are mainly comprehensively used. In order to better cooperate with the special research of sediment mathematical models or physical models, on the basis of selecting advanced and reliable observation instruments for on-site prototype observations, it is required that the supporting observation bracket (platform) can be applicable to the integrated wave-current-sediment comprehensive observation.

[0019] The leveling support structure includes an inner ring 2.1, a middle ring 2.2, and an outer ring 2.3 that are coaxially arranged. The inner ring 2.1 fits under the head of the wave and current observation instrument.

The middle ring 2.2 is rotatably connected to the outer ring 2.3 through two pin shafts II arranged along its radial direction. The pin shaft I is perpendicular to the pin shaft II. On the outside of the outer ring 2.3, there are three connecting ear plates evenly distributed along the circumferential direction. Outside the through hole, there are support platforms corresponding to the connecting ear plates one by one. The connecting ear plates are fixedly connected to the support platforms by bolts 3. For the above leveling support structure, please refer to the utility model patent with the patent number ZL202021652081.0 and the utility model name of a portable stainless steel bottom-mounted wave and current observation platform. The above leveling support structure can keep the wave and current observation instrument in a vertical state all the time, meeting the requirements of the instrument for observing wave and current data in terms of attitude.
