Bottom-sitting-type underwater platform adapting to uneven water bottoms and storing and expanding method of bottom-sitting-type underwater platform

Abstract

The invention provides a bottom-sitting-type underwater platform adapting to uneven water bottoms and a storing and expanding method of the bottom-sitting-type underwater platform. The bottom-sitting-type underwater platform comprises an underwater platform main body, a rigid support set, elastic supports and salvage barrel type auxiliary storing and expanding systems; the rigid support set comprises a plurality of rigid supports which are arranged on the underwater platform main body at intervals; the elastic supports are arranged at the bottoms of the two ends of the rigid supports; and thesalvage barrel type auxiliary storing and expanding systems are mounted in the rigid supports. The bottom-sitting-type underwater platform can provide multi-point elastic supporting and can adapt to mooring of the uneven water bottoms, and the system building cost is lowered.

Description

Technical field [0001] The invention relates to the technical field of underwater special equipment detection, in particular to a sitting-bottom underwater platform suitable for uneven water bottom and a retracting method thereof. Background technique [0002] The underwater platform is the carrying platform for underwater measurement equipment, and its underwater working status has a greater impact on the measurement effect. Under the current fixed-point working mode, underwater platforms mainly include single-point moored buoys, multi-point moored linear underwater platforms, etc. Under a certain flow rate of water, the depth, attitude and heading angle of the single-point tethered platform change greatly and quickly, and require high detection compensation, making it difficult to achieve continuous detection of moving targets. The multi-point moored platform adopts multiple underwater heavy anchors to moor the underwater platform. The position, attitude and heading of the pla...

AI Technical Summary

Problems solved by technology

The long line array underwater floating platform (ZL201110320932.0) that has appeared in recent years is a typical multi-point moored platform, but it is rarely used. The construction cost is relatively high; the second is that there are contradictions between "the linear underwater platform with higher stiffness is difficult to unwind the cable when it is moored at multiple points by restraint" and "the linear underwater platform with lower stiffness is greatly deformed and affects the measurement effect"; Third, the reliability requirements of the system are relatively high, and the maintenance construction after the underwater winch fails is large and the cost is high
