Technical Field

[0001] The invention belongs to the technical field of marine search and rescue equipment, and in particular relates to a marine search and rescue device for people falling into water. Background Art

[0002] Maritime search and rescue refers to the search and rescue work carried out by the state or department in response to maritime accidents. The state has also formulated relevant maritime search and rescue emergency mechanisms to quickly, orderly and efficiently organize emergency response actions for maritime emergencies, rescue people in distress, control the expansion of maritime emergencies, and minimize casualties and property losses caused by maritime emergencies. Maritime search and rescue is more unpredictable than land search and rescue, so it is more difficult. After the crew falls into the water, searching and rescuing the people who fall into the water will be a matter of every second. At present, after receiving the alarm, the domestic coast guard drives a large ship to the scene of the accident, and the coast police drives the ship to carry out rescue at sea. Due to the fluidity of the marine environment, the search range will continue to expand, which will require a large number of police forces to complete the search and rescue work.

[0003] In the existing maritime search and rescue, when a person falls into the water, the crew on the boat throws a life buoy or life jacket to the person and pulls him / her back to the boat, or uses other fishing tools to catch the person. This search and rescue method is time-consuming and labor-intensive, and is likely to delay the best search and rescue time for the person, reducing the search and rescue efficiency for the person and increasing the mortality rate of falling-into-water accidents.

[0042] The working principle of this embodiment is as follows. After a person who falls into the water is found during search and rescue at sea, the rescue personnel drive the rescue hull 1 to the person who falls into the water. The rescue personnel can control the equipment on the rescue hull 1 through the operating table 5 inside the rainproof cabin 4.

The electric telescopic rod 802 drives the salvage frame 803 to extend inside the storage sliding frame 801 through the slide bar 804. The electric lifting rod 809 drives the folding rack 810 to move. The folding rack 810 drives the folding frame 805 to unfold through the folding gear 808. The limit plate 807 limits one side of the folding frame 805. The search and rescue hull 1 is driven slowly to the person who falls into the water. The salvage net 806 has a certain elastic force. The person who falls into the water is salvaged and buffered by the salvage net 806 to prevent secondary damage to the person who falls into the water. Similarly, the salvage net 806 is driven to salvage the person who falls into the water onto the search and rescue hull 1, completing the search and rescue operation for the person who falls into the water at sea.
