Description

Technical Field

[0001] This utility model relates to the field of maritime rescue technology, and in particular to a maritime rescue climbing net. Background Technology

[0002] Maritime rescue is a crucial link in ensuring maritime safety. When a ship is in distress or a person falls overboard, efficient boarding and disembarking tools are needed to transfer the stranded person or allow rescuers to board the ship. Among these tools, climbing nets, as a lightweight and quickly deployable vertical passage tool, are widely used in scenarios such as near-shore rescue, small vessel distress, and transfer between vessels with different elevations.

[0003] Some existing maritime rescue climbing nets require ropes to be used to secure them to the hull surface at key points. This method is not very efficient at securing the net and can waste valuable time and reduce efficiency in emergency rescue situations. If the securing is not done properly, the net may not be secure and may loosen or even slip under the dynamic load of waves or people climbing.

[0004] Therefore, a marine rescue climbing net is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a marine rescue climbing net that solves the problem that some existing marine rescue climbing nets require ropes to be tied to the surface of the ship for securing, which is inefficient and wastes valuable time in emergency rescue scenarios, affecting rescue efficiency. If the tying operation is not standardized, it may lead to insecure fixing, and the tying points may loosen or even slip under the dynamic load of wave impact or personnel climbing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a marine rescue climbing net, comprising longitudinal strips and transverse strips, wherein there are several longitudinal strips and transverse strips, and the surfaces of the longitudinal strips and transverse strips are provided with a hydrophobic layer. Connecting rods are provided on the front and rear sides of the longitudinal strips, and the surfaces of the connecting rods are provided with hanging mechanisms, wherein there are two hanging mechanisms, and the surfaces of the hanging mechanisms are provided with pulling mechanisms.

[0007] The hooking mechanism includes a limiting plate, a hook, a sliding sleeve, and a connecting ring. The rear side of the hook is fixedly connected to the front side of the connecting ring, the top of the sliding sleeve is fixedly connected to the bottom of the hook, and the limiting plate is movably inserted into the inside of the sliding sleeve.

[0008] Preferably, the pulling mechanism includes two first fixing blocks, two tension springs, a second fixing block, and a pull ring. The side of the first fixing block near the sliding sleeve is fixedly connected to the sliding sleeve, the side of the second fixing block near the limiting plate is fixedly connected to the limiting plate, the tension spring is fixedly connected between the opposite sides of the first fixing block and the second fixing block, and the rear side of the pull ring is fixedly connected to the front side of the limiting plate.

[0009] Preferably, a stop block is fixedly connected to the bottom of the connecting ring, and the rear side of the limiting plate contacts the front side of the stop block.

[0010] Preferably, the surface of the connecting rod is provided with a first groove, and there are two first grooves, and the connecting ring is rotatably sleeved inside the first groove.

[0011] Preferably, the front and rear sides of the longitudinal strip are fixedly connected with connecting sleeves, and the connecting rod has a second groove inside that cooperates with the connecting sleeve, and the connecting sleeve is rotatably fitted inside the second groove.

[0012] Preferably, a rubber block is fixedly connected to the inner wall of the connecting sleeve, and the number of rubber blocks is several and evenly distributed inside the connecting sleeve, with the surface of the rubber block in contact with the inner wall of the second groove.

[0013] Preferably, the connection between the longitudinal and transverse strips is provided with a seam, and the connection between the longitudinal and transverse strips is sewn together by the seam.

[0014] Preferably, floats are fixedly connected to both sides of the connecting rod, and the floats are made of polyurethane foam.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application sets up a hooking mechanism, in which the hook is rotatably connected to the first groove of the connecting rod through the connecting ring. The angle can be flexibly adjusted to adapt to different hooking requirements. The limiting plate moves in the sliding sleeve and cooperates with the stop block at the bottom of the connecting ring to restrict the movement of the hook and prevent it from leaving the hull's point of force. It also enables the climbing net formed by the longitudinal and transverse straps to be quickly connected to the hull.

[0017] 2. This application sets up a traction mechanism, in which the pull ring drives the limit plate to move, and the tension spring connects the first fixed block and the second fixed block. When the limit plate moves forward, after the tension spring is stretched, the limit plate can be released and reset by the tension spring retracting, thereby preventing the hook from falling off and improving the connection efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A marine rescue climbing net includes longitudinal strips 1 and transverse strips 2, each having several longitudinal strips 1 and transverse strips 2. The surfaces of both longitudinal strips 1 and transverse strips 2 are provided with a hydrophobic layer 10. Connecting rods 5 are provided on the front and rear sides of longitudinal strips 1. The surfaces of connecting rods 5 are provided with hanging mechanisms 4, and there are two hanging mechanisms 4. The surfaces of hanging mechanisms 4 are provided with pulling mechanisms 7.

[0027] The hooking mechanism 4 includes a limiting plate 401, a hook 402, a sliding sleeve 403 and a connecting ring 404. The rear side of the hook 402 is fixedly connected to the front side of the connecting ring 404, the top of the sliding sleeve 403 is fixedly connected to the bottom of the hook 402, and the limiting plate 401 is movably inserted into the inside of the sliding sleeve 403.

[0028] In this embodiment: by pulling the pull ring 704, the limiting plate 401 moves forward within the sliding sleeve 403, and the tension spring 702 is stretched. Then, after the hook 402 is hooked onto the pre-fixed rod-shaped force point on the hull surface, the pull ring 704 is released, and the tension spring 702 retracts, causing the limiting plate 401 to contact the stop block 6, preventing the hook 402 from detaching from the pre-fixed rod-shaped force point on the hull surface. This achieves a rapid connection between the climbing net composed of the longitudinal belt 1 and the transverse belt 2 and the hull. The longitudinal belt 1 and the transverse belt 2 are woven from nylon filaments and connected by stitching 13. The surface is provided with a hydrophobic layer 10 of silicone-modified polymer coating, which can prevent seawater adhesion and reduce corrosion. The connecting sleeve 9 of the longitudinal belt 1 is fitted into the second groove of the connecting rod 5. Within 11, the rubber block 8 contacts the inner wall of the groove to prevent the connecting rod 5 from rotating under force. The connecting ring 404 rotates within the first groove 12, allowing the hanging mechanism 4 to adjust its angle. The polyurethane foam floats 3 on both sides of the connecting rod 5 provide buoyancy, helping the climbing net to remain floating at sea. This solves the problem that some existing marine rescue climbing nets require ropes to be used to tie the climbing net to the surface of the ship, resulting in low fixing efficiency. In emergency rescue scenarios, this consumes valuable time and affects rescue efficiency. If the binding operation is not standardized, it may lead to insecure fixing, and the binding points may loosen or even slip under the dynamic load of wave impact or personnel climbing.

[0029] Specifically, such as Figure 3 As shown, the pulling mechanism 7 includes two first fixing blocks 701, two tension springs 702, a second fixing block 703, and a pull ring 704. The side of the first fixing block 701 near the sliding sleeve 403 is fixedly connected to the sliding sleeve 403. The side of the second fixing block 703 near the limiting plate 401 is fixedly connected to the limiting plate 401. The tension spring 702 is fixedly connected between the opposite sides of the first fixing block 701 and the second fixing block 703. The rear side of the pull ring 704 is fixedly connected to the front side of the limiting plate 401.

[0030] Specifically, such as Figure 3 As shown, a stop block 6 is fixedly connected to the bottom of the connecting ring 404, and the rear side of the limiting plate 401 contacts the front side of the stop block 6.

[0031] Specifically, such as Figure 2 and Figure 3 As shown, the surface of the connecting rod 5 is provided with a first groove 12, and there are two first grooves 12. The connecting ring 404 is rotatably sleeved inside the first groove 12.

[0032] In this embodiment: the pulling mechanism 7 connects the first fixing block 701 and the second fixing block 703 through the tension spring 702. With the help of the pull ring 704, the limiting plate 401 can be quickly pulled. After being released, the tension spring 702 drives the limiting plate 401 to contact the stop block 6, thereby preventing the hook 402 from falling off and improving the connection stability. The connecting ring 404 rotates in the first groove 12, so that the hooking mechanism 4 can flexibly adjust the angle to adapt to different hull force points.

[0033] Specifically, such as Figure 2 and Figure 4 As shown, the front and rear sides of the longitudinal strip 1 are fixedly connected with connecting sleeves 9, and the inside of the connecting rod 5 is provided with a second groove 11 that cooperates with the connecting sleeve 9. The connecting sleeve 9 is rotatably fitted inside the second groove 11.

[0034] Specifically, such as Figure 2 and Figure 4 As shown, a rubber block 8 is fixedly connected to the inner wall of the connecting sleeve 9. The number of rubber blocks 8 is several and they are evenly distributed inside the connecting sleeve 9. The surface of the rubber block 8 is in contact with the inner wall of the second groove 11.

[0035] In this embodiment: the connecting sleeve 9 is rotatably fitted onto the second groove 11 to connect the longitudinal belt 1 and the connecting rod 5. The rubber block 8 on the inner wall of the connecting sleeve 9 contacts the inner wall of the second groove 11, and can generate friction to restrict the rotation of the connecting rod 5 when the connecting rod 5 is under force, thus ensuring the structural stability during climbing.

[0036] Specifically, such as Figure 4 As shown, a stitch 13 is provided at the connection between the longitudinal strip 1 and the transverse strip 2. The connection between the longitudinal strip 1 and the transverse strip 2 is sewn together by the stitch 13. Both the longitudinal strip 1 and the transverse strip 2 are made of nylon filaments. A hydrophobic layer 10 is evenly sprayed on the surface of the longitudinal strip 1 and the transverse strip 2. The hydrophobic layer 10 is made of silicone-modified polymer coating.

[0037] Specifically, such as Figure 2 As shown, floats 3 are fixedly connected to both sides of the connecting rod 5. The floats 3 are made of polyurethane foam.

[0038] In this embodiment: the longitudinal strip 1 and the transverse strip 2 are woven with nylon filaments and connected by stitch 13, which makes the structure strong. The hydrophobic layer 10 of the silicone-modified polymer coating on the surface can reduce seawater adhesion and corrosion. The polyurethane foam buoy 3 provides buoyancy, helps the climbing net to stay floating, and improves rescue safety.

[0039] Working principle: First, by pulling the pull ring 704, the limiting plate 401, which is fixedly connected to the pull ring 704, will be stretched forward within the sliding sleeve 403. At the same time, the tension spring 702, which is connected to the second fixing block 703 on the limiting plate 401 and the first fixing block 701 on the sliding sleeve 403, is stretched. Then, the hook 402 is engaged with the rod-shaped force point pre-fixed on the surface of the hull. After engagement, the pull ring 704 is released, and the tension spring 702 retracts under its own elastic force, causing the limiting plate 401 to move backward until the rear side of the limiting plate 401 contacts the front side of the stop block 6 fixed at the bottom of the connecting ring 404. This restricts the movement of hook 402, preventing it from detaching from the rod-shaped force point on the hull, and enabling rapid connection between the climbing net composed of longitudinal strips 1 and transverse strips 2 and the hull. Longitudinal strips 1 and transverse strips 2 are woven from nylon filaments, and their joints are sewn together with stitching 13, ensuring the stability of the overall structure. Furthermore, the surfaces of longitudinal strips 1 and transverse strips 2 are uniformly coated with a hydrophobic layer 10 made of silicone-modified polymer paint. This hydrophobic layer 10 effectively prevents seawater from adhering to the surfaces of longitudinal strips 1 and transverse strips 2, reducing seawater corrosion. The connecting sleeves 9 on the front and rear sides of longitudinal strip 1 are rotatably fitted onto the connecting net. Inside the second groove 11 of the connecting rod 5, several evenly distributed rubber blocks 8 on the inner wall of the connecting sleeve 9 contact the inner wall of the second groove 11. When the rescued person steps on the surface of the connecting rod 5, the rubber blocks 8 and the inner wall of the second groove 11 come into close contact, generating friction to prevent the connecting rod 5 from rotating and to ensure stability during climbing. A connecting ring 404 is rotatably fitted inside the first groove 12 on the surface of the connecting rod 5. The hooking mechanism 4 is connected to the connecting rod 5 through the connecting ring 404, allowing the hooking mechanism 4 to rotate relative to the connecting rod 5, which is convenient for adapting to hooking requirements at different angles. At the same time, the connecting rod 5 is fixed on both sides. The float 3, made of polyurethane foam, provides sufficient buoyancy to help the climbing net stay afloat at sea, further improving safety and stability during rescue operations. This solves the problem that some existing maritime rescue climbing nets require ropes to be tied to the surface of the ship, resulting in low fixing efficiency. In emergency rescue scenarios, this wastes valuable time and affects rescue efficiency. If the binding operation is not standardized, it may lead to insecure fixing, and the binding points may loosen or even slip under the dynamic load of waves or personnel climbing.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
