Abstract

The utility model relates to a life buoy for boat, which can be used as a required appliance for rescuing drowned person for various ships. The utility model is composed of a casing (1) and a floating core (2). The utility model is characterized in that the outer layer of the life buoy for boat adopts the annular casing of orange high density polyethylene; the inner of the casing is the floating core (2); the floating core (2) is annular and is filled with polyurethane for foaming and molding; the casing (1) is connected with the floating core (2) tightly to a whole; the casing (1) is provided with a plurality of converse light band grooves (3) and a tie becket hole (4). The hanging strength, the anti-damage, the corrosion-resisting property of the life buoy for boat are all better than the life buoy whose core material adopts styrene.

Description

Life buoy for boat

The utility model relates to a kind of water survival articles for use, is specially adapted to peculiar to vesselly, is that all kinds of ships are the indispensable apparatus of rescue drowning person.

The at present domestic buoy quoit peculiar to vessel that generally uses is be to float core with polystyrene, the outsourcing canvas also is brushed with paint coating, its shortcoming is the mechanical strength of this kind buoy quoit, oil resistant, decay resistance all can not reach the technical standard of international buoy quoit peculiar to vessel, described as (92) No. 680 files of national ship inspection office's product word: " polystyrene has obvious weak point: A for the buoy quoit of floating core on performance; oil resistant; B; weight and size stability; C; intensity ... "; for this reason; national ship inspection general bureau gives notice; no longer allow to use with the buoy quoit of polystyrene foam as core; and this kind buoy quoit that decision was dispatched from the factory later on from June 30th, 1993 is forbidden using on International Voyage Ship; and regulation, for coming of new be provided on the International Voyage Ship buoy quoit and life jacket should it is provided by resolution that adorns the subsides reflex-reflective material by IMOA658.

The purpose of this utility model provides a kind of improved buoy quoit peculiar to vessel, its mechanical strength and oil resistant, decay resistance are all greatly improved than the buoy quoit peculiar to vessel that with the polystyrene foam is core, outsourcing canvas brush paint, and it is easy to use, not fragile, adapt to the needs on the International Voyage Ship.

The utility model can be implemented by following scheme: the utility model comprises housing (1), floating core (2), reflective trough of belt (3) and be becket line hole (4), its feature is in what housing (1) inside, what floating core (2) position, the uppermost layer of floating core (2) is housing (1), housing (1) is a hollow annular housing by the high density polyethylene (HDPE) slush molding, housing (1) thickness is 2-4mm, in housing (1), inject polyurethane material, through on-the-spot superpressure foaming, form the floating core (2) of a ring-type, be called the floating core of polyurethane foam, closely be combined into one with shell (1), housing is orange, several reflective troughs of belt (3) are arranged on the housing (1) and is becket line hole (4).

The utility model has the advantages that: hang intensity, anti-damage that decay resistance is better than all that tradition uses be core with styrofoam, the buoy quoit peculiar to vessel of outsourcing canvas brush paint, reached international technical standard peculiar to vessel, and, because floating core of hard polyaminoester and inner walls is closely compound, thereby the bulk strength and the sealing property of buoy quoit have been improved.

As shown in drawings: (1), housing; (2) floating core; (3) reflective trough of belt; (4) be the becket line hole.

Below, with reference to the accompanying drawings, describe embodiment of the present utility model in detail: the utility model comprises housing (1), floating core (2), reflective trough of belt (3) and be that becket line hole (4) is formed, high density polyethylene (HDPE) is through the moulding of extrusion-blown modling hollow and annular, form housing (1), then to the inner cast of housing (1) hard polyurethane foams core, through on-the-spot superpressure foaming, form the floating core (2) of a ring-type, be called the floating core of isocyanurate foam, closely be compounded to form one with shell (1), so just formed the buoy quoit of a ring-type, sticking reflex-reflective material then on reflective trough of belt (3), is being to mix rope on the becket line hole (4), and according to world buoy quoit requirement peculiar to vessel, shell is orange, and in the prescription of development pigment, add anti fouling composition, UV resistant agent makes not fugitive color of buoy quoit shell, and the buoy quoit of making according to technique scheme and requirement peculiar to vessel has reached international technical standard peculiar to vessel.

Claims

1, a kind of buoy quoit peculiar to vessel, comprise housing (1), floating core (2), reflective trough of belt (3) and be becket line hole (4), its feature is a high density polyethylene (HDPE) circular shell (1) at the uppermost layer of what buoy quoit peculiar to vessel, inner is the floating core (2) of polyurethane foam ring-type, and floating core (2) and housing (1) closely are combined into one.

2, according to the described a kind of buoy quoit peculiar to vessel of claim (1), its feature is preferably 2-4mm at what housing (1) thickness.

3, a kind of buoy quoit peculiar to vessel according to claim 1 and 2, its feature have several reflective troughs of belt (3) and are becket line hole (4) on what housing (1).
