A life-saving net release device and release method for a surface rescue robot

Abstract

The invention relates to a life net releasing device used for a water surface rescue robot and a release method thereof. The life net releasing device comprises a rack body, a support ring below the rack body, and a motor and an electrical push rod fixed over the rack body, the rack body comprises several cantilevers which are uniformly distributed by winding a shaft, pulleys are arranged at an extended end of the cantilevers, a take-up pulley and a ratchet are connected with an output terminal of the motor, each cantilever corresponds to one haulage rope, one end of the haulage rope is fixedat the take-up pulley, the other end winds the pulleys on the corresponding cantilever and is connected with the support ring, the connection points of the haulage rope on the support ring are uniformly distributed along the support ring, the support ring is sealed by a life net, a brake bar is fixed at a telescopic end of the electrical push rod, the brake bar stretches and is capable of clampingthe ratchet, and the rotation of the ratchet cannot be influenced by backing. The people rescued from the river can be hold upwardly, and overturning and sinking cannot be generated.

Description

technical field [0001] The invention belongs to the field of surface rescue, and in particular relates to a lifesaving net release device for a surface rescue robot and a release method thereof. Background technique [0002] At present, when rescuing drowning people at sea and on rivers, most of them are manually driven to the rescue site for search and rescue. Since the golden time for rescuing drowning people is the first 4-6 minutes, if rescue is performed within the golden time, their lives can be saved. The success rate is 90%. In recent years, the large-scale development of aircraft and ships will produce many victims in the event of an accident. referred to as the rescued). In addition, there will be rescued people in areas where rivers are flooded or flooded due to natural disasters such as heavy rain, typhoon, and tsunami. In order to rescue these rescued persons, the following rescue methods are usually arranged: 1) drop the rope from the helicopter, make the re...

Problems solved by technology

[0003] However, when the drowning person is exhausted, neither method 1) nor method 2) can lift the drowning person from under the water surface. For method 1), the drowning person may not be able to find or hold the rope. For method 2), then It is possible to press the drowning person under the rescue belt and fail to catch the drowning person, and the above two rescue methods can only rescue the drowning person on the water surface, but cannot rescue the drowning person submerged in the water, and the rescue process is affected
