Abstract
The utility model discloses a three-layer air chamber lifebuoy which comprises a protection surface layer air chamber, a second protection layer air chamber and a circle core layer air chamber. The diameter of the three-layer air chamber lifebuoy equal to the diameter of a biggest circle of the protection surface layer air chamber is 80 cm, the diameter of a traverse section circle of the three-layer air chamber lifebuoy equal to the diameter of a biggest circle of a traverse section of the protection surface layer air chamber is 16 cm, thickness of the protection surface layer air chamber and the second protection layer air chamber are both about 1 cm, and the protection surface layer air chamber is divided into 144 single closed air chambers. The second protection layer air chamber is wrapped by the protection surface air chamber, the circle core layer air chamber is wrapped by the second protection layer air chamber, so the second protection layer air chamber is arranged between the protection surface layer air chamber and the circle core layer air chamber, and the second protection layer air chamber is divided into 36 single closed air chambers. The circle core layer air chamber is located in the center of the three-layer air chamber lifebuoy and is divided into 12 single closed air chambers. A steel mould with the shape structure is applied, the three-layer air chamber lifebuoy is formed by pouring into the steel mould with plastics or rubbers as materials, and an aeration technology is used, so every single chamber is filled with enough air.
Description
One, technical field
The utility model relates to a kind of water survival instrument, especially relates to a kind of three layers of air-chamber life buoy.
Two, background technology
Buoy quoit a bit produces micropore gas leakage, just loses the lifesaving ability, as for the end user drowned danger occurs, and is a large defective really.
Three, utility model content
In order to overcome the deficiency of above technology, the purpose of this utility model provides a kind of three layers of air-chamber life buoy, by protecting the top layer air chamber, inferior sheath air chamber and circle sandwich layer air chamber form, it is characterized in that, protect the top layer air chamber and be wrapped in time sheath air chamber, be positioned at the appearance aspect of buoy quoit, inferior sheath is wrapped in the circle sandwich layer, inferior sheath and protect the top layer and be provided with each self-enclosed dozens of, even up to a hundred air chambers that volume does not wait, it is shaped as slightly curved hexahedron, circle sandwich layer air chamber is the inflated cylindrical enclosure that is positioned at buoy quoit central authorities, cylindrical enclosure is provided with more than ten each self-enclosed air chamber, the shape of each air chamber is one section slightly curved cylinder, also can be one section slightly curved polyhedron.
The technical scheme that the utility model adopts is, make the following punching block of its shape and structure, the diameter 80cm of buoy quoit, namely protect the diameter 80cm of the circle of top layer air chamber maximum, the girth that protects the great circle in top layer is 80 * 3.14=251cm, the diameter 16cm of the cross-section tangent plane circle of buoy quoit, namely protect the diameter 16cm of the great circle in air chamber square section, top layer, protect the diameter 80-32=48cm of the minimum circle of top layer air chamber, protect the Zhou Changyue 48 * 3.14=150cm of the ringlet in top layer, the thickness that protects top layer air chamber and time sheath air chamber all is each approximately 1cm, undertaken vertically by 30 degree arc length protecting the top layer, laterally be divided into the air chamber of single sealing, then this protects the top layer and is configured to 144 air chambers, and it is shaped as slightly curved hexahedron, the volume of 20 * 4 * 1＞single air chamber＞13 * 4 * 1 (cm3).Protect the top layer and be wrapped in time sheath, inferior sheath is wrapped in the circle sandwich layer, then time sheath is positioned at the centre of protecting top layer and circle sandwich layer, and time sheath is spent the air chamber that 36 single sealings are carried out vertically, laterally are divided into to arc length by 60, each air chamber be shaped as slightly curved hexahedron.Circle sandwich layer air chamber is positioned at buoy quoit central authorities, laterally be divided into 12 closed air chambers by 30 degree arc length, the shape of each air chamber be arc length approximately the radius of 16cm be the cylinder of 7cm, if circle sandwich layer air chamber is set to a circle polyhedron, the single air chamber of circle sandwich layer then is the slightly curved polyhedron that is about 16cm.Use the punching block of above shape and structure, the utility model is produced in cast take plastics or rubber as material, and uses the inflation technology to make each single air chamber that sufficient gas be arranged.
The beneficial effects of the utility model are: protect the single air chamber that there are 144 sealings on the top layer; inferior sheath has the single air chamber of 36 sealings; back up ring sandwich layer air chamber effectively; make whole buoy quoit be in fully inflated situation; even buoy quoit is subject to frustrating hitting to bump and beats and make the somewhere holes occur; also only have some indivedual air chamber gas leakage of protecting top layer air chamber or inferior sheath air chamber, do not hinder the life-saving functions of whole circle, safety factor and the service life of greatly having improved buoy quoit.
Four, description of drawings
Fig. 1 is the structural representation of the utility model vertical section; Fig. 2 is the structural representation that protects the vertical section in top layer; Fig. 3 is the circle sandwich layer structural representation of totally 12 air chambers; Fig. 4 is that the circle sandwich layer is the cross section structural representation of a circle; Fig. 5 is that the circle sandwich layer is the polyhedral cross section structural representation of a circle; Fig. 6 is the structural representation of time sheath vertical section.
Among the figure, 1, protect the top layer; 2, protect the single air chamber in top layer; 3, circle sandwich layer; 4, the single air chamber of circle sandwich layer; 5, protect the maximum circle in top layer; 6, protect the minimum circle in top layer; 7, the maximum circle of inferior sheath; 8, the minimum circle of inferior sheath; 9, the single air chamber of inferior sheath; 10, inferior sheath.
Five, the specific embodiment
As shown in the figure, the utility model is to protect top layer (1) parcel time sheath (10), inferior sheath (10) parcel circle sandwich layer (3) forms buoy quoit, protect (2) 144 of the single air chambers in top layer, (9) 36 of the single air chambers of inferior sheath, (4) 12 of the single air chambers of circle sandwich layer, the equal top off of each air chamber, even buoy quoit is subject to frustrating of external force and hits to bump and beat and make somewhere gas leakage, also just miss the gas of per centum of whole buoy quoit, do not hinder integral body, strengthened the effect of the resisting breakage of buoy quoit, improve the safety factor of lifesaving, prolonged the service life of buoy quoit.
Claims (1)
1. three layers of air-chamber life buoy, by protecting the top layer air chamber, inferior sheath air chamber and circle sandwich layer air chamber form, it is characterized in that, protect the top layer air chamber and be wrapped in time sheath air chamber, be positioned at the appearance aspect of buoy quoit, inferior sheath is wrapped in the circle sandwich layer, inferior sheath and protect the top layer and be provided with each self-enclosed dozens of, even up to a hundred air chambers that volume does not wait, it is shaped as slightly curved hexahedron, circle sandwich layer air chamber is the inflated cylindrical enclosure that is positioned at buoy quoit central authorities, cylindrical enclosure is provided with more than ten each self-enclosed air chamber, and the shape of each air chamber is one section slightly curved cylinder, also can be one section slightly curved polyhedron.
