Abstract

The invention discloses an overwater lifesaving cannonball which comprises a cannonball (1). A plurality of inflatable balloons (2) with inflating tubes are contained in a cannonball head of the cannonball (1), the upper part of a cannonball head shell is a paper body (3), and a heat-insulating layer (4) is laminated on the internal wall of the lower part of the cannonball head shell. The overwater lifesaving cannonball has the characteristic that the cannonball can be rapidly projected to the nearby place of drowning people by a gun carriage, the paper body of the upper part of the cannonball head shell dissolves when the paper body is exposed to water, and all balloons float on the water and are used for being inflated and hugged by drowning people, thus the aim of preventing drowning people from sinking is achieved.

Description

Water survival is used shell

Technical field

The invention belongs to shell, use shell more specifically to a kind of water survival.

Background technology

Be loaded with numerous personnel's the vehicle such as aircraft, train is when the motorcoach accident is fallen into water; Even natatory personnel also can be short of physical strength because of 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, lets it stop to sink to rely on oneself; So that further it is rescued boats and ships or water bank, therefore provide a kind of water survival to have crucial meaning with shell.

Summary of the invention

The purpose of this invention is to provide a kind of water survival and use shell.

A kind of water survival of the present invention is used shell, comprises shell, has the inflation type balloon of several band blowpipes in the bullet of said shell, and the bullet shell upper is the paper body, and lower inner wall has adiabatic layer again.

The present invention has following beneficial effect:

Can apace it be emitted near the drowning crowd by gun carriage, the paper body on bullet jacket top is met aquation and is separated, and each said balloon is bubbled through the water column, and the crowd's inflation that supplies to fall into water is embraced and held up, thereby reaches the purpose that stops its sinking.

Description of drawings

Fig. 1 is the structural representation of a kind of water survival of the present invention with shell.

The specific embodiment

Below in conjunction with accompanying drawing the present invention is done further description.

Shown in Figure 1, a kind of water survival of the present invention is used shell, comprises shell 1, has the inflation type balloon 2 of several band blowpipes in the bullet of said shell 1, and the bullet shell upper is a paper body 3, and lower inner wall has adiabatic layer 4 again.

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

By gun carriage shell of the present invention is emitted near the drowning crowd; The upper reaches of flowing water preferably, the paper body 3 on bullet jacket top is met aquations and is separated, and each said balloon 2 is bubbled through the water column; Supplying drowning crowd's inflation to embrace holds up; Natatory personnel embrace hold up a said 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. a water survival is used shell, comprises shell (1), it is characterized in that, has the inflation type balloon (2) of several band blowpipes in the bullet of said shell (1), and the bullet shell upper is paper body (3), and lower inner wall has adiabatic layer (4) again.
