Description

Technical Field

[0001] This utility model relates to the field of fender technology, and more specifically, to a collision-resistant fender. Background Technology

[0002] Currently, as an important protective device between ships and docks, the material and structural design of anti-collision fenders directly affect their shock absorption and anti-collision effectiveness. Traditional anti-collision fenders are mostly made of solid rubber. Although this material has a certain degree of elasticity and shock absorption, its shock absorption effect is often limited when facing the large impact forces of port-powered ships.

[0003] The shock absorption effect of solid rubber fenders primarily relies on the properties of the rubber material itself. Rubber possesses good elasticity and resilience, enabling it to absorb and disperse some of the impact force, thereby mitigating damage to ships and docks. However, relying solely on the material properties of rubber for shock absorption and collision prevention is often limited by material performance and the operating environment. For example, in extreme weather or sea conditions, rubber fenders may wear, age, or even crack due to prolonged exposure to high-intensity impacts, leading to a significant decrease in their shock absorption effectiveness.

[0004] In conclusion, given the limited shock absorption performance of existing anti-collision fenders, it is necessary to provide an anti-collision fender with better shock absorption. Utility Model Content

[0005] In view of the problems existing in the prior art, this utility model provides a collision protection fender to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a collision protection fender, comprising a mounting frame, an inflatable airbag, an air intake assembly, and an air exhaust assembly, wherein the mounting frame is used to fix the buffer airbag, the buffer airbag is filled with air to absorb the impact force during a ship collision, the air exhaust assembly is used to expel the air inside the buffer airbag when it is subjected to a strong impact, and the air intake assembly is used to replenish the buffer airbag with outside air when it recovers.

[0007] The present invention is further configured such that the exhaust assembly includes an exhaust pipe, a first fixed seat, a first sealing seat, a first fixed plate and a first spring, wherein the first fixed seat and the first fixed plate are both fixed inside the exhaust pipe, one side of the first sealing seat has a first guide rod for guiding the first sealing seat, and the first guide rod passes through the first fixed plate and is slidably connected to the first fixed plate, and the first spring is installed between the first fixed seat and the first fixed plate, and the first spring is sleeved outside the first guide rod.

[0008] The present invention is further configured such that the first fixed seat has a first exhaust port for venting, the first exhaust port is frustum-shaped, and the first sealing seat has a first frustum-shaped surface that mates with the first exhaust port.

[0009] The present invention is further configured such that the first fixed plate has a second exhaust port for exhausting air.

[0010] The present invention is further configured such that the air intake assembly includes an air intake pipe, a second fixed seat, a second sealing seat, a second fixed plate, and a second spring. The second fixed seat and the second fixed plate are both fixed inside the air intake pipe. One side of the second sealing seat has a second guide rod for guiding the second sealing seat. The second guide rod passes through the second fixed plate and is slidably connected to the second fixed plate. The end of the second guide rod away from the second sealing seat has a limiting sleeve. The second spring is installed between the second fixed plate and the limiting sleeve and is sleeved outside the second guide rod.

[0011] The present invention is further configured such that the second fixed seat has a first air inlet for air intake, the first air inlet is frustum-shaped, and the second sealing seat has a second frustum-shaped surface that cooperates with the first air inlet.

[0012] The present invention is further configured such that the second fixed plate has a second air inlet for air intake.

[0013] The present invention is further configured such that the first frustum surface of the first sealing seat faces the inner side of the buffer airbag, and the second frustum surface of the second sealing seat faces the outer side of the buffer airbag.

[0014] The present invention is further provided that the mounting bracket is provided with a through groove.

[0015] The present invention is further provided that the through groove has reinforcing ribs.

[0016] Compared with the prior art, the present invention provides a collision protection fender, which has the following beneficial effects:

[0017] 1. This utility model has a buffer airbag filled with air. When a ship hits the buffer airbag, it deforms under the force, and the internal air is compressed to buffer the impact force. Through the double buffering of the buffer airbag material itself and the internal air, the shock absorption and anti-collision effect is improved.

[0018] 2. When the impact force on the airbag is large, the internal air compression is large, and the airbag is prone to rupture. In this case, the excess air can be discharged through the exhaust component to ensure that the pressure value inside the airbag is within a safe range.

[0019] 3. This utility model has an air intake component. When the buffer airbag is restored without external force, the pressure value of the buffer airbag is the same as that of the outside air, so the air intake component will not take in air. However, when the pressure value inside the buffer airbag is less than that of the outside air after restoration, the outside air will be supplemented into the buffer airbag through the air intake component.

[0030] The anti-collision fender includes a mounting bracket 1, a buffer airbag 2, an air intake assembly 3, and an exhaust assembly 4. The mounting bracket 1 secures the buffer airbag 2, which is filled with air to absorb the impact force during a ship collision. The exhaust assembly 4 expels the air from the buffer airbag 2 when it is subjected to a strong impact. The air intake assembly 3 replenishes the buffer airbag 2 with outside air as it recovers. The exhaust assembly 4 includes an exhaust pipe 401, a first fixing seat 402, a first sealing seat 403, a first fixing plate 404, and a first spring 405. The first fixing seat 402 and the first fixing plate 405... All four components are fixed inside the exhaust pipe 401. One side of the first sealing seat 403 has a first guide rod 406 for guiding the first sealing seat 403, and the first guide rod 406 passes through the first fixing plate 404 and is slidably connected to the first fixing plate 404. A first spring 405 is installed between the first fixing seat 402 and the first fixing plate 404, and the first spring 405 is sleeved outside the first guide rod 406. The first fixing seat 402 has a first exhaust port 407 for exhaust, and the first exhaust port 407 is frustoconical. The first sealing seat 403 has a first frustoconical surface 408 that mates with the first exhaust port 407. The first fixing plate 404 has a second exhaust port 409 for exhausting air. The air intake assembly 3 includes an air intake pipe 301, a second fixing seat 302, a second sealing seat 303, a second fixing plate 304, and a second spring 305. The second fixing seat 302 and the second fixing plate 304 are both fixed inside the air intake pipe 301. One side of the second sealing seat 303 has a second guide rod 306 for guiding the second sealing seat 303. The second guide rod 306 passes through the second fixing plate 304 and is slidably connected to the second fixing plate 304. The end of the second guide rod 306 away from the second sealing seat 303 has a limiting position. The sleeve 307, the second spring 305 is installed between the second fixing plate 304 and the limiting sleeve 307, and the second spring 305 is sleeved outside the second guide rod 306. The second fixing seat 302 has a first air inlet 308 for air intake, the first air inlet 308 is frustum-shaped, the second sealing seat 303 has a second frustum surface 309 that cooperates with the first air inlet 308, the second fixing plate 304 has a second air inlet 310 for air intake, the first frustum surface 408 of the first sealing seat 403 faces the inside of the buffer airbag 2, and the second frustum surface 309 of the second sealing seat 303 faces the outside of the buffer airbag 2.

[0031] The airbag 2 is installed at the dock via the mounting bracket 1. The airbag 2 provides shock absorption for ships approaching the shore. When a ship impacts the airbag 2, it deforms and contracts, compressing the air inside. When the air compression reaches a certain level, the air overcomes the spring force of the first spring 405, pushing the first sealing seat 403 outwards, causing it to leave the first exhaust port 407 of the first fixed seat 402. The air inside the airbag 2 is then discharged into the outside air through the first exhaust port 407 and the second exhaust port 409, preventing... Excessive compression caused the airbag 2 to rupture. After the ship leaves the airbag 2, the airbag 2 recovers and the pressure inside the airbag 2 drops. When the pressure inside the airbag 2 is less than the external pressure, the outside air overcomes the force of the second spring 305 and drives the second sealing seat 303 to move toward the inside of the airbag 2, causing it to leave the second fixed seat 302. The outside air enters the airbag 2 through the first air inlet 308 and the second air inlet 310, so that the air inside the airbag 2 returns to its initial value, so as to buffer the next impact.
