Description

Technical Field

[0001] The invention relates to the field of ship construction equipment, in particular to a windproof floating drum for ship construction water pipelines. Background Art

[0002] The windproof buoy is an important port facility for ships to use in mooring, windbreak, standby, demagnetization, salvage and other operations. The windproof buoy is generally composed of a mooring ring, a drum body, an anchor chain, an anchor body and other parts. The main function of the drum body is to float the anchor chain and mark the position. It needs to have sufficient buoyancy reserve and ensure a certain freeboard height. It also needs to meet certain stability and anti-sinking requirements.

[0003] The current floating drums are directly made of iron cylinders with a certain shape and a cavity as floating drums. The setting is extremely simple, and it is not convenient to retract and release the wire rope guide. In addition, a single wire rope guide is connected to the anchor body, which has low safety. Moreover, when the mooring mechanism has problems, it is not convenient to disassemble and assemble. It is very troublesome to use and maintain, and it cannot achieve the desired effect. Summary of the invention

[0004] The object of the present invention is to provide a windproof floating drum for constructing water pipelines on ships, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A windproof buoy for constructing a pipeline on water, comprising a buoy filled with a foam body, a mounting seat detachably mounted on the top of the buoy, a mooring mechanism detachably mounted on the mounting seat, a first steel wire rope cable guide and a second steel wire rope cable guide extending from the mooring mechanism, the first steel wire rope cable guide and the second steel wire rope cable guide extending to the bottom of the buoy after passing through a central axis through hole, and the first steel wire rope cable guide and the second steel wire rope cable guide placed under the buoy are respectively fixedly connected to two connecting cable buckles on an anchor body;

[0007] The mooring mechanism includes a mooring seat with a mounting groove on its end side, a mounting through hole for accommodating the mooring seat in the middle, a circular cavity corresponding to the mounting groove, an elastic support member rotatably arranged in the circular cavity, a mounting block adapted to the mounting groove mounted on the elastic support member, and an inclined surface on the mounting block;

[0008] The mooring mechanism includes a mooring seat with a retracting rod provided inside, a retracting wheel rotatably provided inside the retracting rod, and a first steel wire rope guide and a second steel wire rope guide extending into the retracting rod are both wound around the retracting wheel in the same direction.

[0009] As a further solution of the present invention: a central axis through hole is opened on the buoyancy box along its central axis, and a first cable guide sleeve and a second cable guide sleeve are fixedly installed in the central axis through hole, wherein the first steel wire rope cable guide and the second steel wire rope cable guide pass through the first cable guide sleeve and the second cable guide sleeve respectively to avoid entanglement and knotting between the first steel wire rope cable guide and the second steel wire rope cable guide located in the central axis through hole.

[0010] As a further solution of the present invention: a long screw is fixedly welded to the bottom surface of the mounting seat, the long screw extends and is inserted into the inner cavity of the buoyancy chamber, and the long screw is installed and fixed by a second mounting bolt.

[0011] As a further solution of the present invention: a reinforcing rod is detachably installed in the buoyancy box through a first installation bolt to ensure the stability of the foam filled in the buoyancy box and to make the filling foam evenly distributed in the buoyancy box.

[0012] As a further solution of the present invention: the elastic support member includes a rotating cylinder rotatably arranged in the circular cavity, and a first elliptical slider and a second elliptical slider are radially slidably arranged in the rotating cylinder respectively, the first elliptical slider and the second elliptical slider are supported and connected by a first supporting spring, the mounting block is fixedly installed on the end of the supporting pressure rod, the other end of the supporting pressure rod slides through and extends into the rotating cylinder and is fixedly connected to the second elliptical slider. Therefore, the first supporting spring arranged in the rotating cylinder has the effect of elastically supporting the mounting block, and when the rotating cylinder rotates, it can drive the mounting block to rotate to achieve the effect of adjusting the direction of the inclined surface on the mounting block.

[0013] As a further solution of the present invention: in order to facilitate the adjustment of the rotation angle of the elastic support, an adjustment shaft is fixedly installed on the first elliptical slider, the other end of the adjustment shaft rotates through and extends to the outside of the mounting seat, and an adjustment disk is fixedly installed on the end of the adjustment shaft extending outside the mounting seat.

[0014] The first elliptical slider can be driven to rotate by operating the adjusting disk. Since the first elliptical slider can only slide radially in the rotating cylinder, the rotating cylinder can be driven to rotate, that is, the rotation angle of the elastic support can be adjusted by operating the adjusting disk.

[0015] As a further solution of the present invention: in order to prevent the elastic support member from self-rotating, the first elliptical slider is connected to the inner wall of the end portion on the same side of the rotating cylinder by a second supporting spring, a second limiting convex tooth is coaxially fixedly installed on the end surface of the adjusting disk facing the mounting seat, and a second limiting tooth groove corresponding to the second limiting convex tooth is provided on the mounting seat;

[0016] At this time, under the elastic support of the second support spring, the second limiting tooth can be embedded in the second limiting tooth groove, so as to achieve the effect of limiting the rotation of the adjusting shaft, that is, to prevent the elastic support member from rotating on its own. When it is necessary to operate the adjusting disk to drive the elastic support member to rotate, you only need to pull the adjusting disk outward until the second limiting tooth is disengaged from the second limiting tooth groove, and then operate the adjusting disk to drive the first elliptical slider to rotate.

[0017] As a further solution of the present invention: a limiting ring block is fixedly installed in the inner cavity of the circular cavity for preventing the rotating cylinder from slipping out of the circular cavity.

[0018] As a further solution of the present invention: an operating part connected to the retracting wheel is also provided on the top of the mooring seat, and the operating part includes a retracting rod fixedly connected to the retracting wheel along the central axis thereof, and an adjusting handle is fixedly installed on the top of the retracting rod. Operating the adjusting handle can drive the retracting wheel to rotate, thereby achieving the effect of retracting / releasing the first wire rope guide and the second wire rope guide.

[0019] As a further solution of the present invention: when there is no need to rotate and adjust the retractable wheel, in order to prevent the retractable wheel from rotating, a radial sliding sleeve is provided on the retractable rod placed above the mooring seat, and the movable limit plate is connected to the adjustment handle through a compression spring support; a first limit convex tooth is coaxially fixedly installed on the end surface of the movable limit plate facing the mooring seat;

[0020] The top surface of the cable seat is provided with a first limiting tooth groove corresponding to the movable limiting disk. When the retractable wheel does not need to rotate, the first limiting protrusion on the movable limiting disk can be pushed to embed into the first limiting tooth groove on the cable seat under the support of the compression spring, thereby achieving the effect of limiting the rotation of the retractable wheel.

[0021] As a further solution of the present invention: a limiting ring block of the retracting rod is placed above the mooring seat, so that the movable limiting plate can only slide radially along the retracting rod without relative rotation.

[0022] Compared with the prior art, the embodiment of the present invention can adjust the direction of the inclined surface on the installation block by operating the adjustment disk to rotate the elastic support member. When the mooring cable seat needs to be installed in the installation through hole, it is only necessary to adjust the inclined surface of the installation block to face upward. At this time, when the mooring cable seat is deeply inserted into the installation through hole, the edge of the end face of the mooring cable seat first abuts against the inclined surface of the installation block, so that the installation block can be retracted into the circular cavity. The mooring cable seat is continuously extended into the installation through hole until the installation block is aligned with the installation groove. Under the pushing action of the elastic support member, the installation block can be embedded in the installation groove, so as to achieve the effect of fixing the mooring cable seat included in the mooring cable assembly in the installation through hole.

[0023] When the retractable and unretractable wheel rotates, the first steel wire rope guide and the second steel wire rope guide can be retracted / released synchronously, so that the windproof buoy provided by the embodiment of the present invention is suitable for different water depth areas, and the embodiment of the present invention provides the first steel wire rope guide and the second steel wire rope guide, which can play a double protection role for the connection with the anchor body, avoiding the problem that the buoy cannot be used any longer due to the breakage of a single guide cable, and in the windproof buoy provided by the embodiment of the present invention, the mooring seat of the mooring mechanism is easy to disassemble and assemble, which facilitates the disassembly and assembly and maintenance of the mooring mechanism.
