Marine lifesaving device

Abstract

The invention provides a water lifesaving device, and belongs to the technical field of lifesaving equipment. The device comprises a U-shaped floating body, a second rotating shaft, two first pushing mechanisms and an auxiliary pushing mechanism, the U-shaped floating body comprises an arc-shaped part and two straight parts, screen cloth is arranged in an opening of the U-shaped floating body, the second rotating shaft is horizontally and rotatably arranged between the rear ends of the two straight parts, and the two first pushing mechanisms are both arranged on the second rotating shaft. The first pushing mechanism comprises a round pipe, a sliding block, a pedal plate and a swinging structure, the round pipe is fixedly arranged on the second rotating shaft, a bottom plate is fixedly arranged at the rear end of the round pipe, the sliding block is arranged in the round pipe in a sliding mode, a reset spring is fixedly connected between the rear end of the sliding block and the bottom plate, and the pedal plate is hinged to the front end of the sliding block through a push rod. When the sliding block slides back and forth in the round tube, the swinging structure can swing up and down to push the U-shaped floating body to move forwards, and the auxiliary pushing mechanism can assist in pushing the U-shaped floating body to move forwards. Sailors can be driven to move around, and the rescue efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of lifesaving equipment, and relates to a marine lifesaving device. Background technique [0002] Due to limited space, small fishing boats are not equipped with power lifesaving equipment on board, and usually only a few lifebuoys are placed on the deck. [0003] When an accident happened to a fishing boat at sea, the crew escaped with the lifebuoy, floated on the sea with the lifebuoy, and swam around relying on their own physical strength. Moreover, some crew members had incorrect swimming postures, and they could only move forward for a short distance after expending a lot of physical strength. They could only wait for rescue. Because their bodies were immersed in the icy seawater for a long time, the crew gradually lost consciousness. If the rescue is not timely, it is easy to cause life danger. Contents of the invention [0004] The object of the present invention is to solve the above-mentioned pro...

Problems solved by technology

[0003]When a fishing boat has an accident at sea, the crew escapes with a lifebuoy, floats in the sea with the lifebuoy, and swims around relying on their own physical strength, and some crew members swim The posture is wrong, and it takes a lot of physical strength to move forward for a short distance. In the end, they can only wait for rescue. Because the body is immersed in the cold sea water for a long time, the crew gradually loses consciousness. If the rescue is not timely, it is easy to cause life danger.
