Modular hand throwing or casting multipurpose drowning prevention foldable buoyant apparatus

Abstract

The invention relates to modular hand throwing or casting multipurpose drowning prevention foldable buoyant apparatus and belongs to the field of machines. The modular hand throwing or casting multipurpose drowning prevention foldable buoyant apparatus comprises a buoyant apparatus shell. A lifesaving airbag is mounted on the head of the buoyant apparatus shell. A protective cover is arranged on the outer side of the lifesaving airbag. A delay air tank with a downward tank opening is mounted on the inner side of the lifesaving airbag. An anti-backflow valve is mounted at the tank opening of the delay air tank. The bottom end of the anti-backflow valve is provided with an air needle extending into the buoyant apparatus shell. A compressed gas cylinder and a rammer are sequentially mounted in the buoyant apparatus shell. The rammer is further connected with a hand throwing module or a casting module and is in linkage with the hand throwing module or the casting module. The buoyant apparatus has the characteristics of being good in flexibility, high in stability, low in using cost, small in size, convenient to carry and the like.

Description

technical field [0001] The invention relates to a life preserver, in particular to a modularized hand-throwing or projectile multipurpose anti-drowning foldable life preserver. Background technique [0002] The anti-drowning life preserver is a relatively common safety equipment. The equipment is mainly used to prevent people from suffocating due to drowning when people accidentally fall into the water or near the water; there are two common types of anti-drowning equipment, wearable and external projectile. [0003] The wearable life preserver is worn on the user's wrist or collar. Take patent 201520633749.X "an anti-drowning bracelet" as an example. In the event of a drowning accident, the user needs to open the high-pressure air valve by pulling the trigger mechanism to make the high-pressure Gas is inflated into the folded airbag; thus the user is lifted out of the water by the buoyancy of the life preserver. However, this type of lifeguard can only be worn on the user...

Problems solved by technology

However, the use of this type of life-saving equipment has limitations: the life-saving equipment that is usually ejected by manpower, due to factors such as the weight and nature of the equipment, the effective projection radius will not exceed 10m, while the life-saving equipment that uses compressed gas and other energy for ejection is usually smaller. Large, such as patent 201310701536.1 "anti-drowning lifesaving ball device"

Once a mistake occurs, it is difficult to have a second chance of recovery
