Description

Technical Field

[0001] The present invention relates to the technical field of intelligent lifesaving equipment, and in particular to a fishing equipment for water surface rescue based on an aircraft platform and a water surface rescue method. Background Art

[0002] At present, there are two main ways to rescue people who fall into the water and catch floating objects using aircraft platforms at sea, especially in offshore environments: the first way is the double lifting method of helicopters, that is, the helicopter first directly drops the lifeguard carrying the lifesaving harness; then, the lifeguard quickly approaches the person who falls into the water and helps him put on the lifesaving harness; then, the lifeguard and the person who falls into the water hug each other and send a lifting signal to the rescue personnel on board; finally, when approaching the helicopter door, the crew will assist them to enter the aircraft. The second way is to use drones to airdrop rescue equipment, that is, the drone approaches the person who falls into the water, drops the rescue equipment to the person who falls into the water, and the person who falls into the water saves himself. The first way requires the use of personnel rescue, which is time-consuming and labor-intensive, lacks good rescue auxiliary equipment, has a high risk, and cannot quickly implement rescue in dangerous environments to ensure the safety of rescue personnel; the second way does not require rescue personnel, but there is a life-saving equipment that can only be operated by the drowning person himself, and cannot actively adapt to the state of the drowning person and the marine environment, and cannot meet the current needs of quickly rescuing seriously injured and disabled people and salvaging materials floating on the sea.

[0038] The fishing net 2 is made of an elastic mesh structure, such as polyester mesh, etc. The fishing net 2 is open at least at one end, and the other end is arranged on a casting mechanism, which provides a rotation torque to utilize centrifugal force to open the fishing net 2 to cover the rescuer.

[0039] The present invention utilizes a throwing mechanism, a flying mechanism 1, a recovery mechanism, an automatic control module and a fishing net 2 to realize intelligent water surface rescue, break through the shortcomings of traditional rescue methods in terms of rescue efficiency, safety and reliability, and solve the problem of rescuing drowning people at sea.

[0040] The flying mechanism 1 in the embodiment of the present invention can be a drone or a manned aircraft, etc., and can be selected according to specific needs. When a drone is used, the operator inputs the mission location, that is, the rescue location, and the drone flies to the rescue location by itself.

[0041] When the identification module is used, the identification module is set on the flying mechanism 1. When the flying mechanism 1 arrives at the rescue position, the identification module is used to determine the relative position of the person who falls into the water and the rescue position. After determining that the horizontal distance error is within Δx and the height difference is within h1, the automatic control module controls the throwing mechanism to throw the fishing net 2 towards the person who falls into the water.

[0042] The specific values ​​of Δx and height difference h1 need to be obtained through multiple preliminary tests and input into the automatic control module in advance. The recognition module can be implemented specifically by using sensors and cameras.

[0043] When a manned aircraft is used as a carrier and no identification module is provided, the throwing mechanism needs to be controlled to throw the object based on the judgment of the pilot or the lifeguard on the aircraft.

[0044] There are many schemes that can realize the casting of the fishing net 2. In a preferred embodiment, the casting mechanism in the fishing equipment for surface rescue provided by the embodiment of the present invention includes a torque output unit 13 and a linear drive unit 12. The linear drive unit 12 is connected to the flying mechanism 1. The torque output unit 13 is arranged at the linear displacement end of the linear drive unit 12. The linear displacement end drives the torque output unit 13 to move up and down. The torque output end of the torque output unit 13 is connected to the top of the fishing net 2, and the torque output unit 13 drives the fishing net 2 to rotate and unfold it.

[0045] Among them, the torque output unit 13 can be in the form of a motor driving the net-casting wheel 5, the motor and the net-casting wheel 5 are connected in transmission to input torque, the upper edge of the fishing net 2 is arranged on the net-casting wheel 5 around the first circle, and the center line of the first circle is colinear with the central axis of the net-casting wheel 5; the linear drive unit 12 can be an electric push rod, and the form of the electric push rod can adopt products in the existing technology.

[0046] In order to further improve the rescue efficiency, in a preferred embodiment, when the automatic control module controls the casting mechanism to cast the fishing net 2, it first controls the torque output unit 13 to output torque. When the recognition module recognizes that the deployment range of the fishing net 2 is within the range S1, it controls the linear drive unit 12 to drive the torque output unit 13 and the fishing net 2 thereon to move downward until the lower edge of the fishing net 2 enters the water and traps the rescuer. Specifically, the depth of the fishing net 2 entering the water can be detected by setting corresponding sensors. When the depth of entry into the water reaches h2, the rescuer is trapped by default.

[0047] In a preferred embodiment, the recovery mechanism includes a winch and multiple ropes, one end of the multiple ropes are wound around the winch's drum 6, and the other end is connected to the lower edge of the fishing net 2, and the multiple ropes are arranged around the circumference of the fishing net 2. The winch drives the drum 6 to rotate and makes the ropes wind around the drum 6 to achieve the purpose of closing the bottom of the fishing net 2 and raising the height of the fishing net 2. The winch is preferably arranged at the linear displacement end of the linear drive unit 12. In order to meet the installation requirements, a support plate can be fixedly set at the linear displacement end, and then the winch and the torque output unit 13 are arranged on the support plate.

[0048] Among them, the top ends of multiple ropes need to be bundled, and in order to achieve the best closing effect, multiple ropes are passed through the top opening of the fishing net 2 and wound around the reel 6, which requires that the net-casting wheel 5 be set into an annular structure, and the ropes pass through the center hole of the net-casting wheel 5. Therefore, the net-casting wheel 5 in this embodiment cannot be directly connected to the motor shaft of the motor. It is necessary to set the edge of the net-casting wheel 5 to a tooth shape, or to set a coaxial driven gear ring at the top or bottom of the net-casting wheel 5, and the driven gear ring is also provided with a center hole to meet the need for threading the rope.

[0050] In a preferred embodiment, a gravity ring is provided at the lower edge of the fishing net 2, and the gravity ring includes a retractable rope ring and a plurality of sinkers arranged in sequence around the circumference of the retractable rope ring. The gravity ring at the lower end of the fishing net 2 will overcome the resistance of the sea water and enter under the person who falls into the water. After confirming that the person who falls into the water is covered, the winch is started to close the gravity ring, and the push rod is retracted at the same time to take the target person away from the sea surface.
