Description

Technical Field

[0001] This utility model relates to the technical field of fender equipment, specifically a rubber fender device made of high molecular weight polyethylene sheet. Background Technology

[0002] Polyethylene (PE) sheet rubber fenders are devices used in docks and other locations to protect ships and dock facilities. They are mainly composed of PE sheets and rubber fenders. PE sheets have high wear resistance, self-lubrication, and corrosion resistance, effectively resisting friction and impact during ship collisions and reducing damage to the ship and the fenders themselves. Rubber fenders have good elasticity and energy absorption properties, absorbing a large amount of impact energy through deformation when a ship docks or collides, thus acting as a buffer and reducing the degree of damage to the ship and dock. This device is installed on the edge of the dock and can be adapted to ships of different types and tonnages. It can be customized according to actual needs and is an important facility to ensure dock safety and ship berthing safety.

[0003] Existing rubber fenders are widely used in dock and ship berthing protection scenarios. However, they are usually fixed in a specific position and cannot be adaptively adjusted according to water level changes. In waters with frequent rises and falls, such as seaports significantly affected by tides and inland river docks with large differences in water level between rainy and dry seasons, the fenders are positioned too high at low water levels, making it easy for ships to collide with the unprotected area below the fenders, resulting in damage to the hull or dock facilities. At high water levels, the fenders are positioned too low, and the impact point of the ship deviates from the effective buffer zone of the fenders, reducing the protective effect and greatly limiting their reliable protective function for ships and dock facilities in complex water level environments. Utility Model Content

[0004] The purpose of this utility model is to provide a rubber fender device made of high molecular weight polyethylene sheet in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-molecular-weight polyethylene sheet rubber fender device, comprising: a mounting base and a rubber protective plate, wherein two sets of symmetrical lifting slide grooves are provided on one side of the mounting base, and limit blocks are fixedly connected to the upper and lower ends of the middle of one side of the mounting base, and a vertical guide rod is fixedly connected between the two sets of limit blocks, and a lifting plate is slidably connected to the vertical guide rod, two sets of symmetrical lifting sliders are fixedly connected to one side of the lifting plate, and a guide hole that vertically penetrates the lifting plate is provided above the lifting plate, and two sets of retaining rings are fixedly connected to both sides of the lifting plate, with floats installed inside the retaining rings.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention, by equipping a pontoon and a lifting structure, can automatically adjust its height according to real-time changes in water level in complex water environments such as seaports significantly affected by tides or inland river wharves with large differences in water level between rainy and dry seasons. When the water level rises, the buoyancy of the pontoon increases, causing the lifting plate to rise smoothly along the vertical guide rod in the lifting groove of the mounting base; when the water level falls, the pontoon drives the lifting plate to fall, always ensuring that the fender device is in the optimal protective position, avoiding blind spots caused by water level fluctuations, and effectively improving the reliability of protection in complex water environment.

The embodiments of this utility model will be described below based on its overall structure.

[0021] Reference Figures 1 to 4In this embodiment of the present invention, a rubber fender device made of high molecular weight polyethylene includes: a mounting base 1 and a rubber protective plate 11. The mounting base 1 has two sets of symmetrical lifting grooves 2 on one side to guide the movement of the components. Limiting blocks 3 are fixed at the upper and lower ends of the middle of one side of the mounting base 1. A vertical guide rod 4 is connected between the two sets of limiting blocks 3. The vertical guide rod 4 is slidably connected to the lifting plate 5. Two sets of symmetrical lifting sliders 6 are fixed on one side of the lifting plate 5. The lifting grooves 2 and the lifting sliders 6 are adapted to and slidably engaged. The lifting plate 5 has a vertically penetrating guide hole 7, which is adapted to and slidably connected to the vertical guide rod 4. Two sets of retaining rings 8 are fixed on both sides of the lifting plate 5. A float 9 is installed in the retaining ring 8. When the water level changes, the float 9 drives the lifting plate 5 to move due to buoyancy. With the sliding connection between the lifting slider 6 and the lifting groove 2, and the vertical guide rod 4 and the guide hole 7, the lifting plate 5 can slide smoothly up and down on the mounting base 1 along the vertical guide rod 4, so that the fender device can automatically rise and fall with the water level and maintain a suitable protective position.

[0022] Regarding the protective buffer structure, a fixed block 10 is fixed to one side of the lifting plate 5, and a movable cavity 12 is provided on one side of the rubber guard plate 11. Four sets of hydraulic buffers 13 are installed between them. Each set of hydraulic buffers 13 is fitted with a spring 14, which is symmetrically distributed at the four ends of the inner side of the movable cavity 12. A high-molecular-weight polyethylene plate is fixed to the outer side of the rubber guard plate 11, and a rubber abutment 15 is fixed to the center of the movable cavity 12. Multiple sets of elliptical air chambers 16 are arranged in parallel inside the rubber guard plate 11, and the chambers are connected by connecting holes 17. When the ship docks and hits the fender device, the high-molecular-weight polyethylene plate, due to its high wear resistance, will provide a strong buffer. With its excellent properties and mechanical strength, the rubber fender 11 initially resists impact and reduces friction. Subsequently, when the rubber fender 11 is subjected to force, the air in its internal air chamber 16 flows through the connecting hole 17, generating a damping effect and absorbing part of the impact energy. At the same time, the hydraulic buffer 13 utilizes the viscous resistance of the liquid and the spring 14, through elastic deformation, to synergistically consume the impact kinetic energy and convert it into elastic potential energy, further buffering the impact. Finally, the rubber block 15 provides the final buffer support at the center of the movable cavity 12, ensuring that the fender device absorbs and disperses the impact energy to the maximum extent, effectively protecting the ship and dock facilities.

[0023] In addition, multiple sets of mounting blocks 18 are provided on both sides of the mounting base 1 to securely install the device in locations such as docks, ensuring its normal operation.

[0024] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0025] The working principle of this utility model is as follows: During daily operation, the float 9 senses changes in water level in real time. When the water level rises, the buoyancy of the float 9 increases, causing the lifting plate 5 to rise along the vertical guide rod 4 within the lifting groove 2 of the mounting base 1. Conversely, when the water level falls, the buoy 9 rises. When a ship collides with the shore, the high-molecular-weight polyethylene plate first resists the impact force and reduces friction. Then, the rubber guard plate 11 is subjected to force, and the air in its internal air chamber 16 flows through the connecting hole 17 to generate a damping effect that absorbs part of the impact energy. At the same time, the hydraulic buffer 13 utilizes the viscous resistance of the liquid, and the spring 14 provides synergistic buffering through elastic deformation. Finally, the rubber block 15 provides final buffer support at the center of the movable cavity 12 to protect the ship and the dock. During the maintenance and repair phase, the appearance of the device should be checked regularly. Check whether the mounting base 1 is stable and not loose, whether the sliding parts of the lifting slide 2 and the lifting slider 6, and the vertical guide rod 4 and the guide hole 7 are worn or stuck, whether the high molecular weight polyethylene plate and rubber guard plate 11 are damaged, and whether the hydraulic buffer 13 and the spring 14 are deformed or ineffective. If any problems are found, repair or replace the corresponding parts in time. Also, clean the surface of the device and the sliding parts of debris and dirt regularly to keep the device clean. If necessary, apply lubricant to the sliding parts to ensure smooth operation. The buoyancy performance of the float 9 should be tested regularly to ensure that it can normally rise and fall with the water level to drive the fender device.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
