Potable water lifesaving device

Abstract

The invention discloses a potable water lifesaving device. The potable water lifesaving device comprises a portable tank body, a compressed air tank arranged in the tank body and a to-be-inflated lifesaving buoy connected with the compressed air tank through a connecting pipe. An electromagnetic valve is arranged on the connecting pipe. The electromagnetic valve is electrically connected with a switch control circuit. The electromagnetic valve is finally electrified and started by turning on a self-rescue switch or a rescue switch of the switch control circuit, and compressed air in the compressed air tank is released to inflate the to-be-inflated lifesaving buoy. The potable water lifesaving device can be projected by hands or machines conveniently and can be projected farther, and rescue and self-rescue can be achieved. The potable water lifesaving device is small in size, convenient to carry, low in cost and suitable for civil use. Rescue and self-rescue are conducted more flexibly through the switch control mode. The compressed air tank can perform inflation and air replenishing, and the application is safer. The lifesaving buoy can be separated from a main body after being inflated through a lifesaving buoy separation device, the weight of the lifesaving buoy is reduced and the rescue ability of the lifesaving buoy is improved. The potable water lifesaving device can be stored for a long time and is more stable than chemical medicine inflation systems in markets, so that the application is safe.

Description

technical field [0001] The invention relates to a lifesaving device, in particular to a portable water lifesaving device. Background technique [0002] About 1,050 people die from drowning every day in the world, and about 388,000 people die from drowning every year. Most of the drowning people were far away from the shore and could not throw the life buoy. When the rescuers arrived, they had already drowned. This is mainly because the life buoy is not easy to carry after it is inflated, or even if the inflated life buoy is carried, it cannot be thrown far or is still inaccurate due to the resistance of the inflated life buoy, and it is difficult to throw it to the rescued person. posed an obstacle. [0003] Some rescue devices can only be carried around or use unstable chemicals, high cost, and are not suitable for civilian use. The applicant has designed a mechanical time-delay lifebuoy and an electronically controlled portable self-inflating lifebuoy to solve the above...

Problems solved by technology

In principle, the method of delayed inflation is adopted, but in actual operation, there is a problem that the delay time cannot be calculated and controlled
