Problems solved by technology

[0003] For example, the invention patents with the publication number CN01143244.6 and the publication number CN113106956 all use an external pump to pump out the water and sediment in the anchor to generate negative pressure, but in the case of deep sea, the distance between the pump and the anchor is relatively long. High-power and high-lift pumps are required to cooperate, and a large amount of space is occupied in the hull for installing anchors and related equipment
[0004] At present, suction anchors are mainly used in soft geological seabeds such as sediment. When the deep-sea seabed is rocky, it is often difficult to install and disassemble or time-consuming methods to install anchoring devices. For some short-term projects In terms of mooring, the cost of mooring is high and the operation is difficult

Abstract

The invention discloses a deep-sea rock seabed suction anchor using a bionic adhesion device. The suction anchor device includes a cylindrical casing, and a partition is arranged in the casing to separate the cavity inside the casing into upper and lower parts. The suction anchor motor and power pack are fixed in the upper cavity, and the suction anchor motor drives the transmission screw to rotate; the transmission screw is threadedly connected with the strut screw sleeve, and the lower end of the transmission screw is fixed with an automatic detection and encryption device, and the lower cavity is separated A cylindrical third auxiliary chamber and a cylindrical first auxiliary chamber and a second auxiliary chamber, the second auxiliary chamber communicates with the third auxiliary chamber through a number of second exhaust holes, the second auxiliary chamber communicates with the first auxiliary chamber It communicates through several first exhaust holes. The beneficial effects of the present invention are: the present invention adopts the bionic structure, which avoids the time-consuming and labor-intensive situation in the past when arranging anchor points in rock geology and will destroy the geology; the piston device is used to generate negative pressure, which reduces the pumping equipment.

Description

technical field [0001] The invention relates to a deep-sea rock seabed suction anchor, in particular to a deep-sea rock seabed suction anchor using a bionic adhesion device. Background technique [0002] The anchoring devices currently used in marine engineering mainly include pile anchors, drag anchors, plate anchors, dynamic installation anchors and suction anchors. At present, the types of suction anchors in my country mainly include gravity suction anchors, double-tube suction anchors and self-installation suction anchors. The suction anchor is generally closed at the top and opened at the bottom, and sinks to the bottom of the sea by its own weight. The soil seals the opening at the bottom of the suction anchor. The anchor passes through the wall barrel to generate negative pressure to absorb the seabed. The seawater pressure acts on the top of the anchor to further press the suction anchor into the formation. internal. Suction anchors are widely used in mooring and f...
