Description
Technical field
The present invention relates to a kind of soft ground suction anchor is device, belongs to the marine installation technical field.
Background technology
There is folding anchor in the anchor system that uses both at home and abroad at present, the grip anchor, admiralty anchor and all kinds of ballast anchors etc., but folding anchor, grip anchor and admiralty anchor etc. generally are used for vessel and stop at the interim pool of the water surface, this is because the anchor of this type is being thrown into when landing the bottom under water, anchor will produce certain grip to ground, by anchor chain vessel is tethered in the certain zone of the water surface and drifts, yet vessel is tethered in and is subjected on the water surface that current are surged and the influence of climate change, the ship that pool stops will be subjected to certain resistance and drift about, " dragging of anchor " phenomenon may appear in this moment, be that sitting duck only will be subjected to displacement and exceed the former area division of berthing, this does not only have much influences to interim sitting duck, but only will have a strong impact on its serviceability to being similar to long-term sitting ducks such as beacon light, will influence the operation in whole navigation channel when serious.The ballast anchor generally is used for carrier is tethered in the water certain depth scope for a long time drifts, and allows a certain amount of displacement.But, for the soft ground bottom, require again the long-term cloth of carrier in water, and do not allow or try one's best the anchor position is changed, promptly do not occur or try one's best " dragging of anchor " phenomenon occurring in time at the bottom of the anchoring part littlely.Need design a kind of suction anchor that is specifically designed to soft ground is device for this reason.
Summary of the invention
The invention provides a kind of soft ground suction anchor is device, this anchor be device lay finish after over the ground mask certain adsorption affinity is arranged, avoided " dragging of anchor " phenomenon substantially.
A kind of soft ground suction anchor is a device, comprises anchor body, orienting sleeve, folding and unfolding rope, adjusts clump weight, adjusts stage clip, hold-down ring, special-shaped seal ring and combined guided ring; The bottom surface of wherein adjusting clump weight is the plate-like arcuate structure, the center is a cylindrical boss, there is vertical through hole at anchor body center, the bottom surface has and adjusts the cooresponding cavity of clump weight shape, the anchor body can be built by reinforced concrete, also can adopt steel plate and strengthening rib welding fabrication, anchor body inside is designed to hollow out formula structure, and requiring according to actual applying working condition can corresponding increase or reduce the ballast lead; Design has the through hole that radially runs through on the circumference of anchor body, is the water resistance of device in water in order to reduce anchor, and the radial design of anchor body has the cavity of axial drain gutter and anchor body bottom surface to connect; Its annexation is: through hole vertical on the anchor body is embedded in orienting sleeve, to guarantee the operating needs of its sealing surface, combined guided ring and suit adjustment stage clip are installed on the cylindrical boss of adjustment clump weight, pack into then in the orienting sleeve in the anchor body, the two ends of adjusting stage clip are respectively with the interior edge of orienting sleeve with to adjust the cylindrical boss of clump weight inconsistent; Adjust the bottom surface of clump weight and the inner ring of special-shaped seal ring and be sulfided into one, adopt fastener to be captiveed joint with anchor body bottom in the outer ring of special-shaped seal ring with hold-down ring.
Principle of work: be that device lays need do micro-adjustment after putting in place the time with the soft ground suction anchor, can make the adjustment stage clip be in pressured state by the moving clump weight of adjusting of traction folding and unfolding strap, discharge the folding and unfolding rope more suddenly, process is for several times from being drawn to the process that discharges the folding and unfolding rope, under the combined action of hydraulic pressure and adjustment stage clip, reaching stocky soft ground, discharge unnecessary ponding in the cavity that forms after the anchor body contacts with ground by the drain gutter on the anchor body, is that device is to ground-surface adsorption affinity to increase anchor; Simultaneously, suction anchor is the variation that device can be subjected to surrounding environment at work by the floating carrier of the water surface or underwater certain depth, drift about back and forth at the water surface or underwater certain depth and to produce certain fluctuating force, fluctuating force is done reciprocal up-and-down movement by the moving clump weight of adjusting of folding and unfolding strap, reaches the purpose of automatic compensation anchor body and soft ground adsorption affinity.
Beneficial effect: the present invention is simple in structure, freedom of motion, working stability, to have strengthened anchor be the seat end ability of device at the soft ground bottom.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the work scheme drawing of the present invention when laying.
Wherein: 1-anchor body, 2-orienting sleeve, 3-folding and unfolding rope, 4-adjust clump weight, 5-adjusts stage clip, 6-hold-down ring, the special-shaped seal ring of 7-, 8 combined guided rings, A-drain gutter, B-through hole.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described in further details.
As shown in Figure 1, soft ground suction anchor of the present invention is that device comprises anchor body 1, orienting sleeve 2, folding and unfolding rope 3, adjusts clump weight 4, adjusts stage clip 5, hold-down ring 6, special-shaped seal ring 7 and combined guided ring 8; The bottom surface of wherein adjusting clump weight 4 is the plate-like arcuate structure, the center is a cylindrical boss, there is vertical through hole at anchor body 1 center, the bottom surface has and adjusts the cooresponding cavity of clump weight shape, anchor body 1 can be built by reinforced concrete, also can adopt steel plate and strengthening rib welding fabrication, anchor body 1 inside is designed to hollow out formula structure, and requiring according to actual applying working condition can corresponding increase or reduce the ballast lead; Design has the through hole B that radially runs through on the circumference of anchor body 1, is the water resistance of device in water in order to reduce anchor, and the radial design of anchor body 1 has the cavity of axial drain gutter A and anchor body bottom surface to connect; Its annexation is: vertical through hole is embedded in orienting sleeve 2 on anchor body 1, to guarantee the operating needs of its sealing surface, combined guided ring 8 and suit adjustment stage clip 5 are installed on the cylindrical boss of adjustment clump weight 4, pack into then in the orienting sleeve in the anchor body 1, the two ends of spring are respectively with the interior edge of orienting sleeve 2 with to adjust the cylindrical boss of clump weight 4 inconsistent; Adjust the bottom surface of clump weight 4 and the inner ring of special-shaped seal ring 7 and be sulfided into one, adopt fastener to be captiveed joint with anchor body 1 bottom in the outer ring of special-shaped seal ring 7 with hold-down ring 6.
