1、 Quick response, racing against time

In traditional water rescue, rescue personnel often need to spend a lot of time arriving at the scene and overcoming natural obstacles such as water flow and obstructed vision.

And with its high-speed flight capability, drones can quickly reach the scene of accidents, conduct preliminary situation assessments, and provide valuable first-hand information for subsequent rescue operations.

2、 Accurate positioning, hitting the key points directly

The high-definition cameras, thermal imagers, and radars carried by drones can accurately identify the location of trapped individuals in complex water environments, even at night or in adverse weather conditions.

This high-precision positioning capability ensures that rescue operations can directly target the core of rescue needs, effectively reducing blind searches and improving rescue efficiency.

3、 Wide coverage

Drones have a wide flight range and can cover large areas of water, greatly improving search and rescue efficiency and ensuring that there are no blind spots in rescue operations.

4、 Reduce risks and ensure safety

Water rescue often comes with extremely high risks, and for rescue personnel, directly entering the water may face life-threatening situations.

The application of unmanned aerial vehicle (UAV) underwater rescue technology, such as deploying lifebuoys and towing buoys, can provide timely assistance to trapped individuals without endangering the safety of rescue personnel. Come on! Charge! Charge! Charge! Charge

From November 13th to 15th, the final of the "2024 City wide Public Security Water Practical Skills Competition" hosted by the Chongqing Public Security Bureau and the Chongqing Federation of Trade Unions, and organized by the Chongqing Public Security Bureau Water Police Corps, will be held at the Changshou Lake Chongqing Water Training Center.

The swimming lanes on the lake rippled with blue waves, and the participating police officers waved their arms and sprinted vigorously. The applause and cheers of the shore audience also echoed one after another.

Boarding, untying, engine starting, S-shaped bending... The fast, shallow draft, and agile assault boat glides across the lake, and as layers of waves splash, the competition is pushed to another climax.

Zong Wei, an auxiliary police officer of Wuxi County Public Security Bureau, skillfully navigated the boat around 5 buoys. Li Luyuan, a police officer accompanying the boat, saw that the machine had thrown the buoy, and the cable was firmly attached to the shore stake.

Sailor skills such as boat driving and cable pulling and berthing are the foundation of our daily water security work. Through practical competitions, we can continuously improve our ability to respond to emergencies, which gives us more confidence in future water rescue work, "said Li Luyuan proudly.

The basic principle of water rescue technology is that 'shore is better than water, teams are better than individuals, and equipment is better than bare hands'. Deng Jianbin, the first level police chief of the Chongqing Public Security Bureau Water Police Corps, has participated in water rescue multiple times and achieved excellent results on behalf of the municipal bureau in national and city wide competitions.

Deng Jianbin stated that the two projects of lifebuoy throwing and collaborative towing of dummy rescue set up in this competition are a special test of the individual combat ability and cooperation level of public security organs in water rescue.

The informatization, technological and intelligent application of water public security work is an inevitable requirement for enhancing the combat effectiveness of new quality public security in the new era. The advantages of high efficiency, accuracy, and coverage of police drones in water reconnaissance, rescue, on-site investigation, etc. will become increasingly prominent due to the large number of water points, long lines, and long distances across the river banks.

At the competition site, police drones equipped with lifebuoys appeared in sequence, climbing vertically from the takeoff and landing point to a height of 5 meters and hovering, ready to take off.

With the command, Ranzhou, the fourth level police chief of Wanzhou Branch of Changhang Public Security, focused on controlling the flight altitude and route; Vice Captain Fu Mingming of the Public Security Detachment adjusted the angle and focal length of the drone camera to maintain a clear and stable image; Third level police chief Ge Jiaxing keeps an eye on weather changes and keeps track of investigation data. Three participating team members worked together and cooperated seamlessly, quickly completing the tasks of fixed point throwing of lifebuoys and 80 meter high-altitude reconnaissance before returning smoothly. Everyone clapped happily to celebrate.

In the subsequent competition for the use of intelligent life-saving equipment, the first level police chief of Changshou District Public Security Bureau, Zhou You, proficiently operated the intelligent lifeboat. He saw an orange red diving and accumulating momentum, like a sharp sword breaking through the water. In just a few seconds, it reached the rescue area 50 meters away from the shore and quickly pulled the "drowning person" back.

After fierce competition, the Nan'an District Public Security Bureau ultimately won the first prize for the group; Wuxi County Public Security Bureau and High tech Zone Public Security Sub bureau won the second prize for the group; Kaizhou District Public Security Bureau, Changshou District Public Security Bureau, and Changhang Public Security Chongqing Branch won the third prize for the group.

This competition has provided a very good platform for everyone to communicate with each other. On November 15th, the water combat skills competition came to a successful end, and Liu Hongyan, the deputy captain of the Seventh Division of the Special Police Headquarters, who was one of the judges, was deeply touched.

Chongqing has a well-developed water system, and our special police have also conducted specialized training in both land and water. This time, we can communicate with each other, learn from each other's strengths and weaknesses, and strengthen the water land linkage and coordination between upstream and downstream, left and right banks, "said Liu Hongyan.

This practical skills competition is based on the water law enforcement practices of public security organs, with a total of 6 projects set up. A total of 22 teams and 131 police officers from 20 districts and counties including Nan'an, Hechuan, Xiushan, as well as Changhang Public Security Chongqing Branch and Changhang Public Security Wanzhou Branch, competed in the preliminary and semi-final rounds to reach the final.
