A water surface rescue device and a rescuer posture state controlling method

Abstract

A rescuer posture state controlling method used in match with a water surface rescue device is disclosed. The method includes automatic system activation, initialization and alarming, a first time ofposture correction, maintaining of a normal forward pushing state and posture control and pushing before rescue, normal in-water rescue state switching, near-distance in-water rescue and normal in-water rescue state maintaining, normal common return voyage state switching and posture control and pushing after rescue, and automatic system delayed turnoff. The method determines the state of a rescuer by utilizing rescuer postures, water pressure, a pressure difference and changing trends thereof. The device adopts a gravity center adjusting module, a counterweight adjusting module and an air inflation module to adjust gravity, floating force and the gravity center position according to a determination result. An implementing process of the method is simple. The method is economical, suitable, rapid in response, labor-saving and safe. The method can assist a rescuer to reach a rescue location in an efficient and labor-saving manner, and can ensure that the rescuer performs safe and reliable rescue operation under the premise of ensuring safety of the rescuer himself or herself.

Description

technical field [0001] The invention relates to a water surface rescue device and a method for controlling a rescuer's posture state, in particular to a labor-saving and safe rescuer's backpack-style water surface rescue device and a rescuer's posture state control method. Background technique [0002] According to an incomplete estimate by the Ministry of Health of my country, about 60,000 people die from drowning every year in the country, which is equivalent to more than 150 people dying from drowning every day. According to the statistics of the World Health Organization (WHO), the number of drowning deaths in China accounts for about 80% of the total number of drowning deaths in the Western Pacific Region of WHO. It can be seen that death by drowning seriously threatens the safety of life and property of our people. [0003] It is worth noting that in the above drowning data, the proportion of drowning deaths in wild waters and rescuers is the same, which shows that re...

Problems solved by technology

[0006] In summary, neither the unmanned water rescue device nor the manned surface auxiliary rescue device can automatically adjust the counterweight (or its own buoyancy) in real time according to the load and its own state during rescue, so as to achieve the purpose of safe and fast rescue. Therefore invent a kind of water surface rescue device, or provide a kind of supporting use of this water surface rescue device, which can assist rescuers to reach the rescue site efficiently and labor-saving (saving physical strength), and can ensure that the rescuer's own safety is carried out scientifically, reliably and in advance. Flexible attitude control of rescue work (that is, using the body posture of the rescuer in the water to control the forward propulsion and steering of the surface rescue device, and at the same time control the overall buoyancy, overall gravity and overall center of gravity of the rescuer during the rescue process in real time position, so that the rescuer always maintains the best posture in the water) method is a key technical problem that designers in this field need to solve urgently
