[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] See Figure 1 and Figure 2 , Figure 1 Shows a climbing diagram of a multifunctional rescue net of the present invention, Figure 2 The present invention provides a multifunctional rescue net, comprising a base 7, which can be arranged near the side of a ship.

[0030] The base 7 can be connected to the side wall of the ship.

[0031] The bracket 4 is rotatably connected to the base 7.

[0032] The bracket 4 can be flipped to the outside of the ship and kept in a horizontal state, and the folding and closing of the bracket 4 is controlled by the rescue personnel 9.

[0033] The net body 1 , one side of the net body 1 can be hung on the bracket 4 .

[0034] The size of the net body 1 is set according to the size of the actual ship, and the lower end of the net body 1 needs to be able to be vertically immersed in the water when hung on the side of the ship.

[0035] In this embodiment, the net 1 is formed by a plurality of crossbars 11 and a plurality of connecting ropes 12 connected horizontally and vertically. The connecting ropes 12 span between the crossbars 11. The crossbars 11 are made of fiberglass rods. The rigid crossbars 11 can be grasped or stepped on by the person 8 who falls into the water, providing strong support. The connecting ropes 12 are made of fire-resistant and wear-resistant webbing, which allows the net 1 to bend.

[0036] Multiple traction ropes 2 are arranged on the other side of the net body 1. The multiple traction ropes 2 can pull the other end of the net body 1 to move when subjected to force, and the net body 1 curls to form an arc-shaped rescue space 3 that can accommodate the person 9 who falls into the water.

[0037] In this embodiment, the number of traction ropes 2 is set to two, and the two traction ropes 2 are respectively connected to the two ends of the same side of the net body 1. Both traction ropes 2 are manually pulled by rescuers, which is convenient for manual adjustment of the position of the net body 1.

[0038] Multiple counterweight blocks 5 are detachably arranged at the lower end of the net body 1.

[0039] Among them, when a person who falls into the water 8 climbs on the net body 1, the counterweight block 5 can increase the weight of the lower end of the net body 1, which can effectively prevent the rescue net from swinging arbitrarily. The number and position of the counterweight blocks 5 can be adjusted according to actual needs.

[0040] See Figure 3 , showing a flow chart of a method for using a multifunctional rescue net of the present invention. The present invention provides a method for using a multifunctional rescue net, comprising the following steps:

[0041] Execute step S210: connect the rescue net to the side of the ship.

[0042] Among them, it is set on the side of the ship, with a large operating space, which is convenient for arranging the net body 1 and can ensure the personal safety of the rescue personnel 9 and the person who falls into the water 8. Then, step S220 is executed.

[0043] Execute step S220: When the rescuer 9 drives the boat close to the waters near the drowned person 8, observe the physical condition of the drowned person 8 to see whether he or she can move independently or cannot move independently.

[0044] Among them, when driving the ship close to the person who fell into the water 8, it is necessary to move slowly to avoid the water waves generated by the movement of the hull from being too large to affect the person who fell into the water 8. During this time, the person who fell into the water 8 can also be observed and instructed on how to ensure his own safety in the water self-rescue posture, and prepare for the rescue. Then, execute step S230.

[0045] Execute step S230: select the deployment method of the rescue net body 1 according to the physical condition of the person 8 who falls into the water.

[0046] The rescuer 9 may select a suitable rescue method according to the actions and the time of falling into the water of the person 8, and then execute step S240.

[0047] Execute step S240: If the person 8 who has fallen into the water is in a state where he can move independently, lower the net 1 to allow the person who has fallen into the water 8 to climb to a safe area on the deck of the ship.

[0048] Among them, the state of being able to move independently means that the person who falls into the water 8 has been in the water for a short time, struggles vigorously, is not injured, and has good physical strength, and is able to grasp the net 1 to complete self-rescue. The rescue measures when the person who falls into the water 8 is in a state of being able to move independently are described in detail below and will not be repeated here. Then, execute step S250.

[0049] Execute step S250: If the person 8 who falls into the water is in a state where he cannot move on his own, lower the net 1 to wrap up the person who falls into the water, and pull him to a safe area on the deck by the rescuer 9.

[0050] Among them, the state of being unable to move independently means that the person who fell into the water 8 has been in the water for a long time, has little struggle, or has been injured and has severely lost physical strength, and cannot grasp the net 1 to complete self-rescue. The rescue measures for the person who fell into the water 8 who is in a state of being unable to move independently are described in detail below and will not be repeated here.

[0051] See Figure 4 , shows a flow chart of step S210 of the present invention. The present invention provides a method for using a multifunctional rescue net, step S210 includes:

[0052] Execute step S211: set up a base 7 near the side of the ship.

[0053] The base 7 can be set on the top of the side or on the inner wall of the side close to the deck. The selection can be made according to actual needs and is not specifically limited here. Then, step S212 is executed.

[0054] Execute step S212: provide a bracket 4 and rotatably set the bracket 4 on the base 7.

[0055] Among them, one end of the bracket 4 is rotatably connected to the base via the pin 71, and then step S213 is executed.

[0056] Execute step S213: hang one end of the net body 1 on the bracket 4.

[0057] The net 1 is unfolded and hung on the bracket 4 .

[0058] See Figure 1 and Figure 5 , Figure 1 Shows a climbing diagram of a multifunctional rescue net of the present invention, Figure 5 The present invention provides a method for using a multifunctional rescue net, wherein step S213 includes:

[0059] Execute step S2131: provide multiple hanging fasteners 6, and connect the end of the net body 1 to the bracket 4 through the multiple hanging fasteners 6.

[0060] The hook 6 can be provided at the end of the connecting rope 12, and corresponding hooks 6 are provided at the ends of the connecting rope 12 on both sides of the net body 1, allowing the net body to be unfolded and ensuring the stability of the force applied to the net body 1. The bracket 4 can be provided with a plurality of spaced hooks for the hooks 6 to connect. The number of hooks 6 is set according to actual needs and is not specifically limited here.

[0061] See Figure 1 and Figure 6 , Figure 1Shows a climbing diagram of a multifunctional rescue net of the present invention, Figure 6 The present invention provides a method for using a multifunctional rescue net, wherein step S240 includes:

[0062] Execute step S241: provide a plurality of counterweight blocks 5, and hang the plurality of counterweight blocks 5 at intervals on the other end of the net body 1.

[0063] Among them, when the net body 1 implements the climbing function, the counterweight block 5 can increase the weight of the rescue net, which can effectively prevent the rescue net body 1 from swinging significantly during climbing, protect the climbing person 8 who falls into the water, and prevent the net body 1 from swinging too much due to force, causing the person 8 to fall into the water again.

[0064] In this embodiment, the counterweight block 5 is provided so as to be detachably snapped onto the connection between the cross bar 11 and the connecting rope 12, and the number of the counterweight blocks 5 provided in the middle part of the net body 1 is greater than the number of the counterweight blocks 5 provided at the edge of the net body 1. This is to adapt to the situation in actual operation that most people 8 who fall into the water choose to climb the middle part.

[0065] See Figure 7 , shows another flow chart of step S240 of the present invention. The present invention provides a method for using a multifunctional rescue net, step S240 further comprising:

[0066] Execute step S242: turn the bracket 4 outside, and unfold the net body 1 along the side wall of the ship and place it vertically.

[0067] Among them, the bracket 4 can be turned outward to the outside of the ship and maintain a horizontal state. The length of the bracket 4 is set to be greater than the width of the net body 1 to ensure that the net body 1 can be unfolded on the bracket 4 to facilitate the person 8 who falls into the water to climb. Then, execute step S242.

[0068] Execute step S243: let the end of the net body 1 with the counterweight 5 hang down into the water.

[0069] The lower end of the net body 1 is arranged to hang down into the water, so that the person 8 who falls into the water and can move independently can grasp it and climb up section by section.

[0070] See Figure 8 , shows a flow chart of step S250 of the present invention. The present invention provides a method for using a multifunctional rescue net, step S250 includes:

[0071] Execute step S251: provide a traction rope 2, connect one end of the traction rope 2 to the net body 1, and use the other end for manual traction by rescuers.

[0072] Among them, two traction ropes 2 are provided, which are respectively connected to the connecting ropes 12 on both sides of the net body 1, and the traction ropes 2 can be manually operated to pull the net body 1.

[0073] See Figure 2 and Figure 9 , Figure 2 A rescue schematic diagram of a multifunctional rescue net of the present invention is shown. Figure 9 Another flow chart of step S250 of the present invention is shown. The present invention provides a method for using a multifunctional rescue net, step S250 further comprising:

[0074] Execute step S252: by pulling the traction rope 2, the net body 1 is curled to form an arc-shaped rescue space 3.

[0075] The traction rope 2 is pulled by the upper tension to move the two ends of the net body 1 closer together, while the middle part of the net body 1 is still drooped by gravity to form an arc.

[0076] In this embodiment, it is necessary to ensure that the length of the net body 1 is such that the bent middle portion of the net body 1 can still hang down into the water after the net body 1 is bent, and a person 8 who falls into the water surface can enter the formed arc-shaped rescue space 3.

[0077] See Figure 10 , shows another flow chart of step S250 of the present invention. The present invention provides a method for using a multifunctional rescue net, step S250 further comprising:

[0078] Execute step S253: accommodate the person 8 who has fallen into the water into the arc-shaped rescue space 3 by adjusting the opening position of the arc-shaped rescue space 3.

[0079] Among them, the openings on both sides of the arc-shaped rescue space 3 and the traction ropes 2 arranged on both sides of the net body 1 can be manually adjusted by the rescuer 9 to adjust the position and size of the openings, so that the person who falls into the water 8 can be better operated to be included in the range of the net body 1.

[0080] See Figure 11 , shows another flow chart of step S250 of the present invention. The present invention provides a method for using a multifunctional rescue net, step S250 further comprising:

[0081] Execute step S254: Pull the person 8 who has fallen into the water to a safe area on the deck by pulling the traction rope 2.

[0082] Among them, the traction rope 2 can pull the net body 1 to roll up the person who falls into the water 8, lift the person who falls into the water 8 above the water surface through the net body 1, and then move the person who falls into the water 8 to the deck of the ship, transfer the person who falls into the water 8 to a safe area, and the rescue is completed.

[0083] In this embodiment, the rescue net can be set on a small ship and a rescue speedboat. After the person who falls into the water enters the arc-shaped rescue space 3, under the buoyancy of the water, the person will gradually leave the water surface as the net body 1 tightens and moves upward. After leaving the water surface, the person can be transferred to the deck with the assistance of the rescue personnel 9 on the deck, thereby ensuring the safety of the person who falls into the water and the rescue personnel.
