Abstract

The utility model discloses a water life-saving cannonball. The water life-saving cannonball comprises a cannonball (1), wherein a plurality of inflation type air balloons (2) with blowing pipes are arranged in the cannonball head of the cannonball (1); a paper body (3) is arranged at the upper part of a cannonball head housing; and a heat insulation layer (4) covers the inner wall at the lower part of the cannonball head housing. The water life-saving cannonball has the characteristics as follows: the water life-saving cannonball can be quickly launched to the position near the crowd falling into water through a cannonball rack, the paper body at the upper part of the cannonball head housing is dissolved when meeting the water, and the air balloons float on the water surface and are inflated and held by the crowd falling into the water, so that the purpose of preventing the crowd falling into the water from sinking is achieved.

Description

The water survival shell

Technical field

The utility model belongs to shell, more specifically to a kind of water survival shell.

Background technology

Be loaded with numerous personnel's the vehicle such as aircraft, train, when the motorcoach accident is fallen into water, even natatory personnel also can be short of physical strength because soaking time is long, need other people relief on bank or the bridge or in the boats and ships, actv. rescue measure is, sends to water life saving apparatus to the crowd who falls into water widely, allows it stop to sink to rely on oneself, in order to further it is rescued upper boats and ships or water bank, therefore provide a kind of water survival to be of great significance with the shell tool.

Summary of the invention

The purpose of this utility model provides a kind of water survival shell.

A kind of water survival shell of the utility model comprises shell, has several in the bullet of described shell with the inflation type balloon of blowpipe, and the bullet shell upper is the paper body, and lower inner wall is covered with adiabatic layer.

The utility model has following beneficial effect:

Can rapidly it be emitted near the drowning crowd by gun carriage, the paper body on bullet jacket top is met the aquation solution, and each described balloon is bubbled through the water column, and embraces for the crowd's inflation that falls into water and holds up, thereby reach the purpose that stops its sinking.

Description of drawings

Fig. 1 is the structural representation that a kind of water survival of the utility model is used shell.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Shown in Figure 1, a kind of water survival shell of the utility model comprises shell 1, has several in the bullet of described shell 1 with the inflation type balloon 2 of blowpipe, and the bullet shell upper is paper body 3, and lower inner wall is covered with adiabatic layer 4.

The global density of each described balloon 2 is with the density less than fresh water.

By gun carriage the utility model shell is emitted near the drowning crowd, the upstream of flowing water preferably, the paper body 3 on bullet jacket top is met the aquation solution, each described balloon 2 is bubbled through the water column, supplying drowning crowd's inflation to embrace holds up, natatory personnel embrace hold up a described balloon 2 after, must continue inflation helping not natatory personnel, thereby reach the purpose that stops the crowd that falls into water to sink.

Claims (1)

1. water survival shell, comprise shell (1), it is characterized in that, have several in the bullet of described shell (1) with the inflation type balloon (2) of blowpipe, the bullet shell upper is paper body (3), and lower inner wall is covered with adiabatic layer (4).
