Description

Technical Field

[0001] The invention relates to the technical field of ship docking auxiliary equipment, and in particular to an auxiliary buffering and collision avoidance device for ship docking and external transmission. Background Art

[0002] Ship berthing operations usually occur at sea, involving two or more ships approaching each other and performing a series of operations, such as cargo transfer, personnel exchange, and replenishment. This operation is very common in the fields of maritime transportation and logistics, maritime rescue and emergency response, offshore operating platforms, and maritime military applications. During this period, orderly and efficient large-scale material transfer requires good coordination between ships, ports, and bridges. In order to ensure the smooth and safe transfer of cargo and personnel from ship to ship, reduce the intensity of ship-to-ship collisions, and thus reduce the operational risks of relative movement between ships to the transfer work, and improve the stability between ships, certain buffering measures must be adopted when ships are berthing.

[0003] At present, the commonly used buffering means mostly adopt air bags and tire buffering methods, which have the following disadvantages: poor automation and low efficiency, the release of air bags or tires and other buffer bodies is mostly manual work, which consumes a lot of physical strength and has huge safety hazards in high sea conditions; the installation position of the buffer body cannot be accurately controlled, and the traditional buffering means generally releases the air bag on the water surface. With the fluctuation of the water surface, the position of the air bag will change, and the large displacement will easily cause it to lose its function as a buffer interval, resulting in a collision between the two ships.

[0023] like Figures 1 to 3 As shown, in this embodiment, an auxiliary buffer collision avoidance device for ships and ships transporting goods outside comprises a ship-to-ship interval support software 1, a bracket 2, and a software retracting and releasing system 3. Figure 4 As shown, the ship-to-ship interval support software 1 includes a stacked outer appendage software 12, a rigid support sheet 11, and an inner appendage software 13. The rigid support sheet 11 is located between the outer appendage software 12 and the inner appendage software 13, and the rigid support sheet 11 is a strength member of the support software. The four corners of the outer appendage software 12, the rigid support sheet 11, and the inner appendage software 13 are rounded. The rigid support sheet 11 is provided with a lifting ear 16, a U-shaped buckle 17 hinged to the lifting ear 16, and a wiring hole 18. The U-shaped buckle 17 is connected to a cable, and the other end of the cable is connected to the software retracting and releasing system 3. The wiring hole 18 is connected to an electric cable. The inner appendage software 13 is provided with a plurality of openings 131, and a spring 14 and an electromagnet 15 are installed in the openings. One end of the spring 14 is fixed to the rigid support sheet 11, and the other end of the spring 14 is fixedly connected to the electromagnet 15. In the non-powered state, the electromagnet 15 is in a contracted state under the traction of the spring 14, so that its outer end surface is slightly lower than the surface of the inner appendage soft body 13. In the powered state, the electromagnet 15 can generate a very strong adsorption force, adsorbed to the outer plate of the hull side, and drive the spring 14 to extend. When the squeeze collision between the two ships occurs, the appendage soft body absorbs the impact and deforms, and the spring in the extended state provides a certain retraction stroke for the electromagnet.

[0024] like Figure 5As shown, the bracket 2 includes a storage tray 20, an air pipe 21, an air pump 26, an air bag 29, a slide 27, and a slide motor 28. The storage tray 20 is closed on all sides and open at both ends, and one end of the storage tray 20 is connected to a guide outlet (201), and the axis of the storage tray 20 is perpendicular to the axis of the guide outlet 201. Figure 6 As shown, roller support grooves 25 are provided on the inner walls of the storage tray 20 and the guide outlet 201. The roller support grooves 25 are single-sided grooves to avoid reducing the strength of the storage tray due to the through grooves. Vertical rollers 22, upper rollers 23, and lower rollers 24 are installed in the roller support grooves 25 to reduce the contact friction between the storage tray 20 and the ship-to-ship interval support software 1. The storage tray 20 is installed on the slide 27, the air pump 26 is fixed on the side of the slide, and the air bag 29 is installed on the side of the guide outlet 201 close to the slide. The air bag 29 is connected to the air pump 26 through the air pipe 21. The slide 27 and the storage tray 20 thereon are controlled to slide by the slide motor 28, and the distance between the storage tray 20 and the ship's side can be adjusted. The air bag 29 serves as a buffer between the guide outlet and the ship's side, so that the lower end of the guide outlet is as close to the ship's side as possible.

[0025] The soft body retracting and releasing system 3 includes a hydraulic jack 31, a push plate 32, a cable retracting and releasing anchor windlass 33, a cable retracting and releasing drum 34 and an anchor windlass motor 35. The push plate 32 is connected to the hydraulic jack 31 and is used to push the ship-to-ship interval support soft body 1. The cable retracting and releasing drum 34 and the anchor windlass motor 35 are installed on the cable retracting and releasing anchor windlass 33. The anchor windlass motor 35 is used to drive the cable retracting and releasing drum 34 to rotate to realize the retracting and releasing of cables and cables. The cable retracting and releasing drum 34 is provided with cable retracting and releasing areas on the left and right sides and a cable retracting and releasing area in the middle, and the cable retracting and releasing areas are divided by a partition. In order to prevent the cable from bearing traction, the effective retracting and releasing length of the cable needs to be greater than the effective retracting and releasing length of the cable.

[0026] The working principle of the present invention is as follows: Figure 7 As shown, the entire device 4 is installed on the deck of the hull 5 near the edge. In the non-working state, the ship-to-ship interval support software 1 is accommodated in the storage tray 20, and the hydraulic top 31 and the push plate 32 are in the recovery state. Before the two ships start the berthing operation, the hydraulic top 31 is controlled to push out the ship-to-ship interval support software 1, and the ship-to-ship interval support software 1 slides horizontally along the rollers in the storage tray 20, and then slides vertically along the guide outlet 201 and is released to the specified position under the traction of the cable windlass. The electromagnet is energized to make the electromagnet adsorbed and fixed on the outer plate of the hull side. After the interval support software is adsorbed and fixed, the push plate and the hydraulic top are restored to the original position, and the rope windlass locks the length of the cable. After the berthing operation of the two ships is completed, when the two ships are separated by a certain distance, the electromagnet is powered off, the interval support software is out of the adsorption state, and the windlass cable retraction and release is started, driving the cable to pull the interval support software along the storage tray to the original position.

[0027] The present invention is suitable for the working environment when two ships are juxtaposed, and can effectively reduce the collision intensity caused by the relative movement of the two ships when juxtaposed, thereby ensuring the safety and smoothness of the working process. It can also realize the automatic throwing and recovery of the auxiliary buffer collision avoidance device, and improve the efficiency and safety of the buffer body installation; by setting an electromagnet in the interval support software, the position of the interval support software is fixed, and the buffer body is prevented from changing position with the water body, which causes the buffering effect to fail, thereby ensuring the buffering effect of the interval support software.
