Water surface rescue device

Abstract

A water surface rescue device comprises a shell, a driving steering module, an inflating module, an attitude and water pressure detection module, a main system module, a back rack, a power supply module, a gravity center position adjusting module and a counterweight adjusting module; the inflating module can provide additional buoyancy; the attitude and water pressure detection module can monitoran attitude and state of a rescuer; the counterweight adjusting module comprises water storage tanks, a water injection and drainage pump, a water injection and drainage control valve, a gas exhaust hole and a water injection and drainage hole; the water storage tanks are fixedly arranged on the two sides of the interior of a middle chamber in a symmetric manner; the water injection and drainage hole, the water injection and drainage pump, the water injection and drainage control valve and a water injection and drainage opening are connected with each other through pipelines in sequence; a gasinlet and exhaust opening is connected with the gas exhaust hole; the gas inlet and exhaust opening selectively communicates with the gas exhaust hole and a gas storage cylinder by using a gas inletand exhaust switching control valve. By using the counterweight adjusting module together with the gravity center position adjusting module and the inflating module, the buoyancy, gravity force and gravity center position can be adjusted within a large range so that the rescuer is always kept in an optimal water entry attitude.

Description

technical field [0001] The invention relates to a water surface rescue device, in particular to a labor-saving and safe portable water surface rescue device. 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 among the above drowning data, the proportion of drowning deaths in wild waters and rescuers is the same, which shows that rescue in wild waters is difficult and the risk of rescue is high. The reasons are as follows: On the one hand, th...

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, inventing a water surface rescue device, especially a manned water surface auxiliary rescue device with low cost, simple operation, easy portability, quick response, flexibility, labor saving, safety and reliability, is a key technical problem that designers in this field urgently need to solve.
