All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a ship anchor with hydraulic assistance comprises an anchor fluke 1, an anchor arm 2 and an anchor chain 3, wherein the anchor chain 3 is connected to the joint of the anchor fluke 1 and the anchor arm 2, the joint of the anchor fluke 1 and the anchor arm 2 is movably connected with a rotating arm 4, the tail end of the rotating arm 4 is provided with a pressing sleeve 5, the pressing sleeve 5 wraps the back of the anchor arm 2, the pressing sleeve 5 is provided with an anchor ring 6, the anchor chain 3 passes through the anchor ring 6 to transmit pressure to the back of the anchor arm 2, a tension spring 7 is arranged between the rotating arm 4 and the anchor arm 2, the pressing sleeve 5 is pressed on the back of the anchor arm 2 by using spring force, the anchor arm 2 is fixedly connected with a double-rod compression cylinder 8, the anchor arm 2 is provided with a side wall oil pipe, not shown in the figure, the head of the anchor arm 2 is fixedly connected with a rotating wheel 11, the rotating wheel 11 is provided with an elastic device to ensure that the rotating wheel 11 is pressed on a seabed, the, the runner 11 drives the double-rod compression cylinder 8 to stretch out and draw back when rotating, the piston rod on the other side of the double-rod compression cylinder 8 is movably connected with the anchor chain 3 or the rotating arm 4 through the second connecting rod 10, the angle change of the anchor chain 3 or the rotating arm 4 drives the other piston rod of the double-rod compression cylinder 8 to stretch out and draw back, the hydraulic ejection piece 12 is arranged inside the fluke 1, the hydraulic ejection piece 12 is communicated with the double-rod compression cylinder 8 in a one-way mode, the hydraulic pressure in the hydraulic ejection piece 12 rises along with the stretching of the double-rod compression cylinder 8, and the hydraulic ejection piece 12 is pushed out.
Referring to fig. 2, an elastic damping sleeve 13 with a thin top and a thick bottom is disposed on the inner wall of the pressing sleeve 5, a neck with a wide top and a narrow bottom is disposed at a corresponding position of the anchor arm 2, the surfaces of the elastic damping sleeve 13 and the anchor arm 2 are both rough, the pressing sleeve 5 is tightly attached to the back of the anchor arm 2 by the combined action of friction and the tension of the tension spring 7, and the force required for separating the pressing sleeve 5 can overcome the increase of the tension spring 7, so that the rotating arm 4 rotates to the other side.
Referring to fig. 3, the hinge point of the rotating arm 4 is closer to the root than the connection point of the tension spring 7 and the anchor arm 2, the included angle between the connection line from the connection point of the tension spring 7 and the anchor arm 2 to the head end of the anchor arm 2 and the connection line to the hinge point of the rotating arm 4 is less than ten degrees, the rotating arm 4 rotates by a small angle to stretch the tension spring 7 to the longest, and finally rotates in the other direction under the action of the tension force of the tension spring 7, and the second connecting rod 10 is fixedly connected with the anchor chain 3, so that the interference caused by the length is avoided by the bending of.
Referring to fig. 4, the hydraulic ejection member 12 includes an elastic buffer cylinder 121 disposed inside the anchor arm 2 and a tree-shaped hydraulic passage 122, the elastic buffer cylinder 121 is expandable, when the anchor is initially set, the expansion of the elastic buffer cylinder 121 absorbs hydraulic oil caused by the rotation of the runner 11, an external accommodating cavity of the elastic buffer cylinder 121 is communicated with the outside of the anchor arm 2, the hydraulic passage 122 is equipped with a plunger 123, the plunger 123 is fixedly connected with a top plate 124, the high pressure inside the elastic buffer cylinder 121 drives the plunger 123 to eject outwards, an outlet side of the plunger 123 narrows to prevent the plunger 123 from sliding out, and a spring is disposed to make the top plate 124 be located in a groove when not being stressed, so as to prevent the sliding out from interfering with the anchor setting.
Referring to fig. 5, the anchor arm 2 is widened, the top plate 124 is a transverse rectangular plate, which increases the surface area, reduces the local pressure, and avoids inserting into the reef, the bottom of the top plate 124 is fixedly connected with at least three transverse plungers 123, which increases the ejection pressure of the top plate 124, the plungers 123 are perpendicular to the top surface or the bottom surface of the anchor arm 2, on one hand, the upper surface has a relatively low thickness, which makes it easier to break the reef when pushing upwards, and on the other hand, the two ends have a pressure to push outwards, so that the reef can be pushed out before the reef is broken.
The working principle and the working process of the invention are as follows:
when the anchor is retracted, if the anchor is not clamped, the smaller acting force can turn over soil at the moment, the anchor is pulled out, if the anchor is clamped, the acting force along with the anchor lifting is increased, the acting force is larger than the pulling force of the tension spring 7 and the friction force of the pressing sleeve 5, the pressing sleeve 5 is separated from the anchor ring 6, the rotating arm 4 rotates to the other direction, the acting force directly acts on the root of the anchor at the moment, the anchor is pulled out, if the anchor can not be pulled out still, the angle of the anchor chain 3 and the rotating arm 4 is changed by repeatedly loosening and retracting the anchor chain 3, the double-rod compression cylinder 8 repeatedly stretches when the second connecting rod 10 is driven, the oil pressure in the elastic buffer cylinder 121 and the hydraulic channel 122 rises, the plunger 123 and the top plate 124 are ejected out, and the reef can be ejected or ejected out due to the fact that general rocks are compression-resistant and not tensile.
When encountering large stormy waves, if the anchor begins to turn over and move with soil, the rotating wheel 11 rotates along with the movement of the anchor, so that the double-rod compression cylinder 8 stretches and retracts, the top plate 124 is controlled to be ejected out, the resistance of the anchor in forward movement is increased, and the stormy wave resistance of the anchor is increased.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
