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 ...

AI Technical Summary

Problems solved by technology

The positioning signal of this positioning method has a certain position drift or the equipment is damaged after being flooded and cannot continue to transmit signals, or no one calls the police after the vehicle accident falls into the water, etc.

Moreover, the installation of the signal device to realize this positioning method requires cost, and there is currently no legal requirement for mandatory installation, so it is impossible to achieve 100% coverage of the installation

We first need to make sure that when the car is running on the wading bridge section, the ownership of the vehicle may be the government, company, collective or individual. We mandate that every car must be equipped with a positioning device after the vehicle falls into the water, even if the device is cheap Or free of charge, we also need to consider the economic ability and personal wishes of the vehicle owner. Some vehicles will always drive in a non-wading area. It is unreasonable to force them to install a positioning device after the vehicle falls into the water, so we mustn't think about installing something on the vehicle body to solve this problem

Even if some vehicle owners install a positioning device in consideration of their own safety, we still need to consider who will receive the signal emitted by the positioning device. This is a device that requires passive positioning and cannot be received by ordinary equipment. Signal, for rescue, this is an unnecessary and very time-consuming process

[0003] Currently known underwater positioning equipment on the market, such as: river bed side-scan sonar, underwater radar, underwater robots and other automation equipment, the automation equipment has the following problems: Firstly, it takes a long time to locate, secondly, it requires a professional team to operate, thirdly, the procurement cost can easily range from hundreds of thousands to millions, fourthly, there is a possibility of damage and failure, and there is also the possibility of launching positioning through frogmen and water ghosts, but in each city, There are very few people with diving qualifications. Even if there are, it does not rule out that the person concerned cannot arrive in time at that time, and there is a certain danger in entering the water.
