Abstract

The invention discloses a life buoy with a double-layered air chamber, which is manufactured in a shape structure of a following steel mould. The diameter of the life buoy is the diameter of a maximum circle of an air chamber of a surface protection layer, which is about 80 cm; the diameter of a circle on the cross section of the life buoy is the diameter of a maximum circle on the cross section of the air chamber of the surface protection layer, which is about 16 cm; the diameter of a minimum circle of the air chamber of the surface protection layer is 48 cm; the circumference of the minimum circle of the surface protection layer is about 150 cm; the thickness of the air chamber of the surface protection layer is about 1 cm; and the surface protection layer is divided into 144 individual sealed air chambers which are vertically and transversely divided according to an arc length of 30 degrees. A circle core layer is coated by the surface protection layer; a circle core layer is located at the center of the life buoy and is transversely divided into 12 sealed air chambers according to the arc length of 30 degrees. With the adoption of the steel mould in the shape structure, the life buoy with the double-layered air chamber is manufactured by pouring a material such as plastic or rubber, and each individual air chamber is sufficiently inflated by using an inflating technology.

Description

The two-layer air chamber buoy quoit

One, technical field

This creativity and innovation relates to a kind of water survival instrument, especially relates to a kind of two-layer air chamber buoy quoit.

Two, background technology

Buoy quoit a bit produces micropore gas leakage, just loses the lifesaving ability, as for the end user drowned danger takes place, and is a big defective really.

Three, summary of the invention

In order to overcome the deficiency of above technology, the purpose of this creativity and innovation provides a kind of two-layer air chamber buoy quoit, forms with circle sandwich layer air chamber by protecting the top layer air chamber; It is characterized in that, protect the top layer air chamber and be wrapped in circle sandwich layer air chamber, be positioned at the appearance aspect of buoy quoit; Protect the top layer and be provided with osed top dozens of even up to a hundred the air chambers that volume does not wait separately; It is shaped as slightly curved hexahedron, and circle sandwich layer air chamber is the inflated cylindrical enclosure that is positioned at buoy quoit central authorities, and cylindrical enclosure is provided with more than ten osed top air chamber separately; The shape of each air chamber is one section slightly curved cylinder, also can be one section slightly curved polyhedron.

The technical scheme that this creativity and innovation adopted is to make the following punching block of its shape and structure, the about 80cm of the diameter of buoy quoit; Just protect the about 80cm of diameter of the maximum circle of top layer air chamber, the girth that protects the great circle in top layer is 80 * 3.14=251cm, the about 16cm of diameter of the cross-section tangent plane circle of buoy quoit; Just protect the about 16cm of diameter of the great circle in air chamber square section, top layer; Protect the about 80-32=48cm of diameter of the minimum circle of top layer air chamber, protect the Zhou Changyue 48 * 3.14=150cm of the ringlet in top layer, protect the about 1cm of thickness of top layer air chamber; Carry out vertically, laterally be divided into single osed top air chamber protecting the top layer by 30 degree arc length; 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 the circle sandwich layer; 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 all is that the radius of the about 16cm of arc length is the cylinder of 7cm, if circle sandwich layer air chamber is set to a circle polyhedron, then single circle core air chamber then is the slightly curved polyhedron that is about 16cm.Using the punching block of above shape and structure, be that this creativity and innovation is produced in the material cast with plastics or rubber, and utilization inflation technology makes each single air chamber that sufficient gas arranged.

The beneficial effect of this creativity and innovation is: protecting the top layer has 144 single air chambers of osed top; Protect whole buoy quoit to be in fully inflated situation effectively; Even buoy quoit receives frustrating to hit to bump and beats and make the somewhere holes occur; Also have only and somely protect the top layer air chamber and leak gas, do not hinder the lifesaving function of whole circle, greatly improved the safety factor and the service life of buoy quoit.

Four, description of drawings

Fig. 1 is the structural representation of this creativity and innovation 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.

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.

Five, the specific embodiment

As shown in the figure, this creativity and innovation is to protect top layer (1) parcel circle sandwich layer (3) to form buoy quoit, protects (2) 144 of the single air chambers in top layer; (4) 12 of circle sandwich layer single air chambers, the equal top off of each air chamber hits to bump and beats and make somewhere gas leakage even buoy quoit receives frustrating of external force; 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. a two-layer air chamber buoy quoit is formed with circle sandwich layer air chamber by protecting the top layer air chamber, it is characterized in that; Protect the top layer air chamber and be wrapped in circle sandwich layer air chamber; Be positioned at the appearance aspect of buoy quoit, protect the top layer and be provided with osed top dozens of even up to a hundred the air chambers that volume does not wait separately, 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 osed top air chamber separately, and the shape of each air chamber is one section slightly curved cylinder, also can be one section slightly curved polyhedron.
