Abstract

The utility model discloses a buoyancy chamber which aims to provide a buoyancy chamber with the advantages of light structure, good shock resistance, good stability and convenient transportation and delivery. The utility model comprises a core pipe (1) and floating bodies (2, 3, 4), wherein the floating bodies (2, 3, 4) are fixedly connected to the periphery of the core pipe (1) through a central hole (20) in series, each of the float bodies (2, 3, 4) is composed of an elastic foam inner core (21) and an elastic armour (22) coated on the surface of the elastic foam inner core (21), and a gap is not arranged among the elastic foam inner cores (21) and the elastic armours (22). The utility model can be applied to the field of a navigational mark.

Description

A kind of floating chamber

Technical field

The utility model relates to a kind of floating chamber.

Background technology

Buoy is the important aids to navigation of marine operation safety, and its radical function is direction, boundary and the danger that indicates the navigation channel, discloses relevant navigation channel information, for safe, economic navigation channel is pointed out in ship's navigation.Present buoy has floating chamber's structure mostly, so that buoy can swim on the water surface.Floating chamber's quality of the inner hollow that metals such as existing employing iron and steel are made is bigger, and in order to have enough buoyancy, its volume is also relatively large, thereby the structure heaviness, has increased the consumption of metallic material; When the floating chamber is subjected to wind outside, wave, stream, ice etc. and impacts, because the area that is hit is big, more violent rocking often taking place, has influenced the stability of buoy; Because the structure heaviness, thereby transport, throw in inconvenient.

So existing product has the following disadvantages: the structure heaviness, shock resistance is poor, poor stability, transportation, input inconvenience.

The utility model content

Technical problem to be solved in the utility model is the deficiency that overcomes on the prior art, provides that a kind of structure is light and handy, shock resistance good, good stability, transportation, throws in floating chamber easily.

The technical scheme that the utility model adopted is: the utility model comprises core pipe, at least one buoyancy aid, described buoyancy aid is fixed in described core pipe periphery by the centre hole serial connection, described buoyancy aid is made up of elastic foam inner core and the elasticity armor that is coated on described elastic foam core surface, does not have the gap between described elastic foam inner core and the described elasticity armor.

Described elastic foam inner core is made by high molecular foam material, and described elasticity armor is made by polyureas or polyurethane or polyurethane and polyureas mixture.

Described core pipe is metal tube or High molecular material pipe.

The beneficial effects of the utility model are: because buoyancy aid described in the utility model is by the elastic foam inner core be coated on its surperficial elasticity armor and form, there is not the gap between described elastic foam inner core and the described elasticity armor, described elastic foam inner core is made by high molecular foam material, such high molecular foam material has good physical property and processing characteristics, its density is low, buoyancy is big in water, therefore volume can dwindle more existing floating chamber greatly, simultaneously oeverall quality of the present utility model is significantly reduced; Again since described elasticity armor make by polyureas or polyurethane or polyurethane and polyureas mixture, such material has better physical property and processing characteristics, its impact resistance, deformation-recovery performance, excellent anti-corrosion performance, can be by the aqueous corrosion of rivers,lakes and seas, and these materials can also recycling, so the utility model structure is light and handy, and little, the light weight of volume, shock resistance is good, withstanding corrosion, easily processing, life-span are long, and environmental protection;

Because the more existing floating chamber of the utility model volume is little, when the utility model was subjected to wind outside, wave, stream, ice etc. and impacts, its area that is hit was little, therefore can reduce impact force, was difficult for being blocked or clasping by floating ice displacement; Again because elasticity armor impact resistance described in the utility model, deformation-recovery performance are good, therefore can further reduce collision and impact, strengthened the stability of floating chamber, so the utility model good stability;

Owing to the utility model structure is light and handy, the quality of comparing with existing floating chamber significantly reduces, so the utility model uses, safeguards, transports, throws in conveniently.

Description of drawings

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of the utility model buoyancy aid.

The specific embodiment

As Fig. 1, shown in Figure 2, the utility model comprises core pipe 1, three

buoyancy aids

2,3,4, described

buoyancy aid

2,3,4 are fixed in described core pipe 1 periphery by centre hole 20 serial connection, described

buoyancy aid

2,3,4 are made up of elastic foam inner core 21 and the elasticity armor 22 that is coated on described elastic foam inner core 21 surfaces, there is not the gap between described elastic foam inner core 21 and the described elasticity armor 22, described elastic foam inner core 21 is made through high-pressure foam by EVA (ethene-vinyl acetate poly-mer), its abscess is a closed pore state, water absorption rate is very low, foaming body has the better physical performance, and foaming body can be regulated its physical property such as pulling strengrth according to different purposes, hardness, ductility etc., can certainly adopt other high molecular foam material to make, as other plastics or plastics and rubber mixture or polyurethane, described elasticity armor 22 is made by polyureas, this material is a kind of new material, has more excellent physical property, can certainly be mixed and made into by polyurethane or polyurethane and polyureas, described core pipe 1 is a stainless steel tube, can certainly adopt other metal tube or High molecular material pipe, the plastic pipe that for example adopts PE (polyethylene) or PVC (polyvinylchloride) to make.

Described

buoyancy aid

2,3,4 is captiveed joint in the following way with described core pipe 1: in each described

buoyancy aid

2,3,4 centre hole 20 two keyways 6 are set respectively, cooperate with protruding key 5 on being fixedly set in described core pipe 1 outer wall by described keyway 6 described

buoyancy aid

2,3,4 and described core pipe 1 are fixedly connected.Can certainly adopt other connection mode, for example the pipe face interference fit by described

buoyancy aid

2,3,4 centre holes 20 and described core pipe 1 is fixedly connected described

buoyancy aid

2,3,4 and described core pipe 1, perhaps adopts bonding to wait alternate manner to connect.

Buoyancy aid described in the utility model is the bead string type structure, and the number of described buoyancy aid is not limited to three, as long as satisfy the buoyancy requirement, buoyancy aid of minimum employing gets final product, and can certainly adopt more buoyancy aid as required.

The utility model can be applicable to domain of navigation mark.

Under the situation that does not break away from the present utility model thought, all application the utility model specification sheetss and accompanying drawing content and the various equivalences of being done change, and all reason is with being contained in the claim scope of the present utility model.
