Description

Technical Field

[0001] The utility model relates to a protective device in the field of ship side protection, in particular to an air cushion type ship side protection device. Background Art

[0002] When special vessels are lifting / deploying torpedoes, submersibles, unmanned boats, or rescuing personnel at sea, it is inevitable that the hoisted objects or personnel will collide with the hull. In addition, the same is true when special vessels are performing special tasks such as salvage, rescue, and supply at sea. Therefore, the anti-collision design issue must be fully considered before performing the task. At present, the more common method is to install permanent steel fenders or rubber fenders at a wider freeboard position above the waterline, mainly to actively protect the hull of the mother ship to prevent other ships or objects from colliding with the ship and causing damage. If protection is not required in non-fender areas, active protection is generally temporarily provided by manually operated portable fenders or inflatable floats to prevent foreign objects from colliding with the mother ship and causing mutual damage. The flexible fenders and floats provide "two-way protection", such as Figure 1 The structure is shown.

[0003] However, if all freeboard above the waterline is permanently equipped with steel or rubber fenders, it will significantly increase the weight of the ship, adversely affecting the overall performance and economy of the ship. To meet the collision avoidance requirements below the waterline, installing steel or rubber fenders below the waterline is equivalent to adding underwater appendages, which will also have a significant impact on the resistance and heading stability of the ship during navigation. In addition, there are a series of problems such as increased manufacturing and maintenance costs.

[0004] In addition, if Figure 1 With the existing structure shown, during offshore lifting / deployment operations, the hoisted object will inevitably collide with the hull due to the effects of wind, waves, and currents. A specific length range on the side requires full protection from a certain depth below the waterline to the side deck edge. In this case, there is a lack of effective buffering devices, making the hoisted object susceptible to impact and damage. Furthermore, the manually operated portable fenders or inflatable floats are susceptible to wind, wave, and current effects, making them difficult to secure and resulting in protection failure, and even accidents. As the impact force increases, the compressive strength of individual fenders and floats must be increased, which in turn increases their size and weight. This makes manual control even more difficult, and the requirements for speed, safety, and reliability cannot be met. Utility Model Content

[0005] The utility model provides an air cushion type ship side protection device which has a simple structure and can meet the requirements of rapidity, safety and reliability.

[0006] The air cushion type ship side protection device described in the utility model includes a plurality of air bags vertically distributed on the side outer plate and an inflation and deflation device for inflating and deflation of the air bags. The top of the air bag is provided with a connecting pipe connected to the inflation and deflation device. A plurality of pairs of elastic wing plates are symmetrically arranged on both sides of the air bag in the vertical direction. One end of the wing plate is connected to one side of the air bag, and the other end is fixed to the side outer plate through a fixing piece.

[0007] Furthermore, it also includes a gel coat arranged between two adjacent airbags, the inner side of the gel coat is smooth and flat and glued to the outer surface of the airbag, the outer side of the gel coat is provided with anti-slip round protrusions, and a window for the fixing part to pass through is opened at the position of the gel coat corresponding to the fixing part.

[0008] Furthermore, the airbag is a combined airbag with a tubular upper portion and a conical lower portion.

[0009] Furthermore, the fixing part includes a bolt welded to the side outer plate, one end of the wing plate is sleeved on the bolt, a gasket with rounded corners that fits the wing plate, and a nut that is tightened to fix the wing plate is screwed on the bolt.

[0010] Furthermore, the wing plate is also provided with a hole hoop for fitting onto the bolt.

[0011] Furthermore, reinforcing ribs for fixing the wing panels are provided on both sides of the airbag.

[0012] Furthermore, talcum powder is provided in the airbag.

[0013] Furthermore, the connecting pipe includes branch pipes connected to each airbag and a main pipe connected to each branch pipe, and the main pipe is connected to the inflation and deflation device.

[0014] Furthermore, the inflation and deflation device includes an air compressor and a vacuum pump, one end of the connecting pipe is connected to the air compressor, and the other end of the connecting pipe is connected to the vacuum pump.

[0015] The air cushion type ship side protection device is fixed to the side of the ship through the wing plates on both sides and the fixing parts. The inflation and deflation device can quickly inflate or deflate the airbag by vacuum suction. When the airbag is in the inflated state, the elastic wing plates on both sides are stretched at the same time to generate a reaction tensile force acting on the airbag, which can effectively fix the airbag to the side outer plate, and can play a two-way buffering and protection role for the side and the suspended objects, preventing other ships or objects from colliding with the ship and causing damage. The structure is stable and safe. When the airbag is deflated, the airbag on both sides of the airbag is Under the action of the elastic wing's rebound tensile force, the airbags are quickly and neatly retracted back into position against the side plate, allowing the airbags to quickly and effectively fit the side. The airbags form an invisible side protection coat, like a "sheet" spread flat on the side plate, without obvious "attachments". There is no need to pull them up for recovery, and underwater attachments are avoided, which would increase the resistance to the ship's navigation and reduce the ship's heading stability. This meets the need for rapid switching between rapid airbag contraction during navigation and airbag inflation for buffering and protection of the side during special operations. The utility model has the characteristics of simple structure, stealth, drag reduction, rapid switching, and light weight, taking into account the ship's high navigation speed and protectiveness during lifting and lowering operations.

[0027] like Figure 2-8As shown, an air cushion-type ship side protection device includes several airbags 1 vertically distributed on the side shell and an inflation and deflation device 2 for inflating and deflation of the airbags. A connecting pipe 3 connected to the inflation and deflation device 2 is provided on the top of the airbag. Multiple pairs of elastic wings 4 are symmetrically arranged along the vertical direction on both sides of the airbag 1. One end of the wing is connected to one side of the airbag, and the other end is fixed to the side shell via a fixing member 5. Furthermore, an elastic wing is also provided on the bottom plate of the airbag, and the bottom of the airbag is fixed to the side shell via the wing. The airbag is fixed to the side of the ship by the cooperation of the wing panels on both sides and the fixing parts. Its inflation and deflation device quickly inflates or deflates the airbag by vacuum suction. When the airbag is inflated, the elastic wing panels on both sides are stretched at the same time to generate a reaction tensile force acting on the airbag, which can effectively fix the airbag to the side shell and provide buffering protection for the side and the suspended objects in both directions, preventing other ships or objects from colliding with the ship and causing damage. The structure is stable and safe. When the airbag is deflated, the elastic wing panels on both sides of the airbag quickly and neatly retract the airbag back into place and close to the side shell under the action of the rebound tensile force, so that the airbag can quickly and effectively fit the side of the ship. The airbag forms an invisible side protection coat, like a layer of "bed sheet" spread flat on the side shell, without obvious "attachments". It does not need to be pulled up for recovery, and it avoids the generation of underwater attachments, which increases the resistance to the ship's navigation and reduces the heading stability. It meets the needs of quickly switching between quickly shrinking the airbag during navigation and inflating the airbag for buffering protection of the side during special operations. The utility model has the characteristics of simple structure, stealth, resistance reduction, fast switching and light weight, and takes into account the speed of ship navigation and the protection of lifting operation.

[0028] The device also includes a gel coat 6 positioned between two adjacent airbags 1. The inner side of the gel coat is smooth and flatly bonded to the outer surface of the airbags. The outer side of the gel coat 6 is provided with anti-slip bumps 601, and windows 602 are provided in the areas of the gel coat corresponding to the fixings, allowing the fixings to pass through. The gel coat is made of a wear-resistant, non-slip, and waterproof material and is attached to the outer surface of the airbags, connecting all the airbags together. The airbags and wing panels can also be made of rubber. By providing anti-slip bumps on the outer side of the gel coat and bonding the smooth inner side of the gel coat to the rubber airbags with glue, all vertically arranged airbags can be connected to form a single, square airbag protective cushion. This geometrically increases the impact contact area and significantly reduces the impact pressure when the impact force is constant, effectively improving the protective performance and reliability of the protective device. This allows the airbag diameter to be directly reduced, achieving a compact and lightweight design. Furthermore, windows are provided in the areas of the gel coat corresponding to the fixings, allowing the fixings to pass through, facilitating assembly and disassembly of the airbags for maintenance.

[0029] The airbag 1 is a combination of a circular tubular upper portion 101 and a conical lower portion 102. When the waterline is narrowed, the combination of the circular tubular upper portion and the conical lower portion prevents the suspended object from being rolled under the ship while the airbag is inflated, and the suspended object remains within the sight of those on deck throughout the entire process.

[0030] The fixing member 5 includes a bolt 501 welded to the side outer plate, one end of the wing plate is inserted into the bolt, a gasket 502 with rounded corners that fit the wing plate, and a nut 503 that is screwed onto the bolt to secure the wing plate. The wing plate 4 is also provided with a ferrule 401 that fits over the bolt. When the airbag is deflated and laid flat perpendicular to the waterline, the elastic wing plates on both sides of the airbag are inserted through bolts pre-embedded in the side, and the gaskets are reinstalled and the nuts are tightened to secure the wing plates and airbag to the side. The ferrule ferrule clamps the surrounding wing plates, increasing the contact area and preventing damage to the wing plates and repeated stretching and tearing. When the airbag is inflated, the elastic wing plates on both sides are simultaneously stretched, generating a reaction tensile force acting on the airbag, effectively securing it to the side. When the airbag is deflated, the tensile force of the elastic wing plates on both sides quickly retracts and secures it to the side. Among them, the material of the bolts should be consistent with the material of the side outer plate (for example, if the steel of the side outer plate is steel / stainless steel, if the side outer plate is aluminum, it is aluminum). The root of the bolt is welded and fixed to the side outer plate. The specific installation position and quantity match the hole clamps of the elastic wing plates on both sides of the airbag. The length of the bolt should be adapted to the thickness of a locking nut. The exposed protruding ends of the bolts should be rounded to prevent sharp corners from scratching rubber parts, such as airbags, wing plates or gel coats; the material of the gasket is preferably non-metallic material, such as nylon, and the edges and corners of the gasket or long strip pad are rounded to prevent sharp corners from scratching rubber parts; the nut material should be stainless steel 316L, and thread locking glue should be applied before tightening the nut to prevent the nut from loosening and falling off.

[0031] Reinforcement ribs 7 for fixing the wing panels are provided on both sides of the airbag 1. The airbag and the wing panels are connected by the reinforcement ribs, which can increase the connection strength between the airbag and the wing panels and prevent the wing panels from repeatedly stretching and tearing the airbag.

[0032] The airbag is provided with talcum powder. The talcum powder provided in the airbag can be repeatedly inflated to fill the inner wall of the airbag with talcum powder, thereby preventing the inner wall of the airbag from sticking due to overheating, adapting to the high temperature environment at sea, and improving the reliability of the device.

[0033] The connecting pipe 3 includes a branch pipe 301 connected to each airbag and a main pipe 302 connected to each branch pipe. The main pipe is connected to the inflation and deflation device. The branch pipes and the main pipe can be made of a hose or a hard metal pipe.

[0034] The inflation and deflation device 2 includes an air compressor and a vacuum pump. One end of a connecting pipe is connected to the air compressor, and the other end is connected to the vacuum pump. When the airbag needs to be inflated, the air compressor is activated to inflate the airbag; when the airbag needs to be deflated, the vacuum pump is activated to deflate the rubber airbag. This allows for rapid inflation and deflation, meeting the needs of rapid switching between navigation and special operations.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
