Quick positioning device for accident vehicles falling into water

Abstract

The invention provides a quick positioning device for an accident vehicle falling into water, which comprises a positioning net, a connecting device, a magnetic attraction device and a floating object, the positioning net is arranged on the side surface of a wading bridge, two ends of the positioning net in the length direction are correspondingly fixed at two ends of the bridge in the length direction, and the positioning net comprises at least two net single bodies; the connecting device is used for connecting two adjacent net single bodies, so that the net single bodies are connected end to end to form a positioning net; magnetic attraction devices are arranged on the net single bodies and used for being attracted to an accident vehicle to enable the net single bodies to fall along with the accident vehicle; the net single bodies are fixedly connected with floaters through ropes, and the length of the ropes is larger than the depth of water. And the positioning floating balls are connected with the positioning net through high-strength Kevlar fabric fiber ropes. A diver can launch water according to the position of the rope, find the vehicle falling into the river at the first time and anchor and hoist the vehicle, the process that the vehicle loses direction for multiple times due to turbid water after launching is omitted, and time is saved.

Description

technical field

[0001] The invention relates to the technical field of lifesaving devices specially used in water, in particular to a rapid positioning device after an accident vehicle falls into the water. Background technique

[0002] For rescue, there is one way of rescue. For water rescue, the most important thing is "fast". For the public and the staff involved in the rescue, what they need to see is an objective and obvious sign. No matter which urban area, no matter day or night, no matter spring, summer, autumn and winter. In the market, all positioning devices that can be found are passive positioning devices. For example, GPS or Beidou signal transmitters are implanted in the car, and the mobile phones of the drivers and passengers are used for positioning. However, this positioning method requires special signal reception. terminal to receive positioning signals. The positioning signal of this positioning method has a certain position drift, or the equipment is ...
