Fixed deep sea platform discardable adsorption preventing bottom sitting device

Abstract

A fixed deep sea platform discardable adsorption preventing bottom sitting device comprises a fixed sludge preventing plate. The two ends of the fixed sludge preventing plate are provided with movablesludge preventing plates through rotation shafts correspondingly. The inner sides of the movable sludge preventing plates are connected with the middle position of the upper surface of the fixed sludge preventing plate through double-torsion springs. The upper surfaces of the parts, beside the double-torsion springs, of the fixed sludge preventing plate are provided with torsion spring baffles. Pin rod guides are arranged at the middle portions of the outer sides of the two movable sludge preventing plates. A horizontal pin rod further transversely penetrates through the bottom of the fixed sludge preventing plate. A vertical rod is hinged to one end of the horizontal pin rod and penetrates through the pin rod guide on one side, the other end of the horizontal pin rod is hinged to a shortrod, the short rod is connected with a pin rod spring, the pin rod spring penetrates through the pin rod guide on the other side, and locking is conducted through a fixing lug plate at the end portion. Two guiding blocks are symmetrically arranged on the upper surface of the fixed sludge preventing plate, a supporting base is nested between the two guiding blocks, a lower lock ring of a semicircular structure is fixed in the supporting base, and a lock ring structure for installing a platform support is formed by two upper lock rings and the lower lock ring. Work is reliable.

Description

technical field [0001] The invention relates to the technical field of bottom-sitting devices, in particular to a disposable anti-adsorption bottom-sitting device for a fixed deep-sea platform. Background technique [0002] At present, manned or unmanned fixed large-scale deep-sea platforms used for deep-sea geological environmental conditions, cold seeps, and deep-sea species research generally need to sit on the bottom of the sea for dozens of days or even months. In order to be able to sit on the bottom of the muddy seabed for marine scientific research, fixed deep-sea platforms usually need to be installed with fixed bottom supports to slow down the silting of the deep-sea platform in the muddy seabed. Then, there are the following typical problems in the design of this bottom-seat device: the bottom-seat bracket is fixed on the deep-sea device, and the bottom-seat bracket is silted in the silt, which is equivalent to the deep-sea device being silted in the mud. If the a...

Problems solved by technology

Then, there are the following typical problems in the design of this bottom-seat device: the bottom-seat bracket is fixed on the deep-sea device, and the bottom-seat bracket is silted in the silt, which is equivalent to the deep-sea device being silted in the mud. If the area of ​​the bottom-seat bracket and the silt is too large, , once the contact part falls into the silt, the silt will also face the problem of excessive adsorption from the bottom; if the area is too small, it will cause the bottom bracket to sink into the silt, which will also cause excessive adsorption
