Description

Technical Field

[0001] This utility model relates to the field of fender technology, specifically to a multifunctional protective rubber fender. Background Technology

[0002] Rubber fenders, also known as rubber guards, are installed on docks or ships to absorb collision energy between ships and docks or between ships when berthing or mooring, protecting ships and docks from damage. Generally, rubber fenders can be divided into two main categories based on their structure: solid rubber fenders (non-floating type) and floating rubber fenders. Solid rubber fenders (non-floating type) are the earliest and most widely used anti-collision devices for docks and ships. Based on the stress conditions they experience, they can be further classified as shear type, rotation type, and compression type, etc. Based on their structure, solid rubber fenders can also be classified as D-type, conical, drum-shaped, fan-shaped, rectangular, cylindrical, etc.

[0003] For example, Chinese patent CN 220549186U proposes a floating rubber fender. This patent adjusts the existing horizontal floating rubber fender to a vertical floating rubber fender, which can maintain a vertical position. Thus, part of the rubber fender extends below the waterline, which can effectively improve the stability of the ship when berthing. However, in this solution, the rubber fender needs to be fixed during use, and the water level will rise or fall depending on factors such as rain. The main function of the fender is to reduce the impact force between the ship and the dock and prevent or eliminate damage to the ship and dock structure. When the water level rises and submerges the rubber fender, the fender cannot play its due buffering role, and the ship may directly collide with the dock. Utility Model Content

[0005] A multifunctional protective rubber fender includes a mounting frame, on one side of which a rubber fender body is mounted, and on another side of which a PLC controller is mounted. A sliding frame is movably fitted inside the mounting frame. A floating assembly is disposed on both sides of the mounting frame to allow the rubber fender body to float. The floating assembly includes two floating tanks, each fixedly mounted on one side of the mounting frame. Mounting holes are fixedly mounted on both sides of the mounting frame, and a first transparent plate is fixedly fitted inside each mounting hole. A connecting hole is formed on the outer circular wall of each floating tank. A second transparent plate is fixedly installed in the floating tank. A buoyancy block is movably fitted inside the floating tank. A movable hole is fixedly installed on the outer circular wall of the buoyancy block. A U-shaped frame is fixedly installed on the outer circular wall of the movable hole. A magnet is fixedly installed inside the U-shaped frame. Mounting grooves are opened on both sides of the sliding frame. Magnets are fixedly installed inside the mounting grooves. A water inlet is opened on the bottom surface of the floating tank. A submersible solenoid valve is fixedly fitted on the inner circular wall of the water inlet. The submersible solenoid valve is electrically connected to the PLC controller. A drainage component for discharging water from inside the floating tank is provided inside the floating tank.

[0006] To lower the water level inside the floating tank and allow the buoyancy block to naturally descend, the drainage assembly of this multifunctional protective rubber fender preferably includes: a support pipe, which is fixedly installed inside the floating tank; a fixing hole is provided on the outer circular wall of the support pipe; a placement platform is fixedly installed on the inner circular wall of the floating tank; a submersible pump is fixedly installed on the top surface of the placement platform; a drain pipe is fixedly sleeved on the outer circular wall of the submersible pump outlet; the drain pipe is fixedly sleeved with the fixing hole; drain holes are respectively provided on the top surfaces of the floating tank and the support pipe; water outlet pipes are fixedly sleeved on the inner circular walls of the two drain holes; and the support pipe is movably sleeved with the movable hole.

[0007] In order to detect the water level and ensure that the center of the rubber fender body is in the water, as a multifunctional protective rubber fender of this utility model, preferably, a fixing ring is fixedly installed on one side of the sliding frame, and a float liquid level sensor is fixedly sleeved on the inner circular wall of the fixing ring, and the float liquid level sensor is electrically connected to the PLC controller.

[0008] To reduce the impact force on the rubber fender body, as a multifunctional protective rubber fender of this utility model, preferably, two buffer grooves are opened on one side of the sliding frame, a fixing block is fixedly installed on the outer circular wall of the rubber fender body, two buffer columns are fixedly installed on one side of the fixing block, the buffer columns are movably sleeved with the buffer grooves, and springs are movably sleeved on the outer circular wall of the buffer columns, with the two ends of the springs fixedly installed on one side of the fixing block and the sliding frame, respectively.

[0009] In order to enable the sliding frame and the rubber fender body to move smoothly up and down, as a multifunctional protective rubber fender of this utility model, preferably, the top surface of the sliding frame is provided with a moving hole, and a stabilizing column is fixedly installed inside the mounting frame, and the stabilizing column is movably connected to the moving hole.

[0010] In order to increase the impact buffering force of the rubber fender body, as a multifunctional protective rubber fender of this utility model, preferably, a number of air cushions are fixedly installed on the outer circular wall surface of the rubber fender body.

[0011] In summary, the present invention has the following main advantages:

[0012] The system utilizes a mounting frame, rubber fender body, sliding frame, floating tank, first transparent plate, second transparent plate, buoyancy block, U-shaped frame, magnet, magnet, and submersible solenoid valve in a coordinated manner. When the submersible solenoid valve is opened, water is poured into the floating tank. As the water level rises, the buoyancy block floats up. The buoyancy block rises with the water entering the floating tank. When the buoyancy block, U-shaped frame, and magnet move upward, the magnet will drive the magnet, sliding frame, and rubber fender body to move upward as well. This ensures that the air cushion remains at the water surface as the water level rises, preventing the fender from failing to provide proper cushioning when the water level rises to submerge the fender, thus preventing the ship from directly impacting the dock and increasing the risk of damage to the hull and dock.

[0021] 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.

[0022] Example 1: Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6A multifunctional protective rubber fender includes a mounting frame 1. A rubber fender body 2 is mounted on one side of the mounting frame 1, and a PLC controller is mounted on another side of the mounting frame 1. A sliding frame 3 is movably fitted inside the mounting frame 1. Floating components are provided on both sides of the mounting frame 1 to allow the rubber fender body 2 to float. The floating components include two floating tanks 4, which are respectively fixedly mounted on both sides of the mounting frame 1. Mounting holes 5 are fixedly mounted on both sides of the mounting frame 1, and a first transparent plate 6 is fixedly fitted inside the mounting holes 5. A connecting hole 7 is provided on the outer circular wall of the floating tank 4 for connection. A second transparent plate 8 is fixedly installed inside the hole 7. A buoyancy block 9 is movably fitted inside the floating tank 4. A movable hole 10 is fixedly installed on the outer circular wall of the buoyancy block 9. A U-shaped frame 11 is fixedly installed on the outer circular wall of the movable hole 10. A magnet 13 is fixedly installed inside the U-shaped frame 11. Mounting grooves 14 are respectively opened on both sides of the sliding frame 3. Magnets 15 are fixedly installed inside the mounting grooves 14. A water inlet hole 22 is opened on the bottom surface of the floating tank 4. A submersible solenoid valve 21 is fixedly fitted on the inner circular wall of the water inlet hole 22. The submersible solenoid valve 21 is electrically connected to the PLC controller. The floating tank 4 is equipped with... A drainage assembly is provided for discharging water from inside the floating tank 4. By using a submersible solenoid valve 21, the mounting bracket 1 and the rubber fender body 2 are placed in the water and installed on the shore, leaving most of their area above the water surface. When the water level rises, the submersible solenoid valve 21, located at the bottom of the floating tank 4 and below the water surface, opens, allowing water to flow into the floating tank 4. The increased water level inside the floating tank 4 causes the buoyancy block 9 to rise, and at this point, the buoyancy block 9 will move with the water level. The water poured into the floating tank 4 rises to a higher position, which in turn moves the U-shaped frame 11 and the magnet 13 as the buoyancy block 9 moves upward. Since the magnet 13 and the magnet 15 are attracted together, when the buoyancy block 9, the U-shaped frame 11 and the magnet 13 move upward, the magnet 13 will move the magnet 15, the sliding frame 3 and the rubber fender body 2 upward. This allows the air cushion 12 to remain at the water surface as the water level rises, preventing the fender from failing to perform its proper buffering function when the water level rises to submerge the fender, thus preventing the ship from directly hitting the dock and increasing the risk of damage to the hull and the dock.

[0023] Example 2: Based on Example 1 above, referring to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7The drainage assembly includes a support pipe 16, which is fixedly installed inside the floating tank 4. A fixing hole 17 is formed on the outer circular wall of the support pipe 16. A placement platform 18 is fixedly installed on the inner circular wall of the floating tank 4. A submersible pump 19 is fixedly installed on the top surface of the placement platform 18. A drain pipe 20 is fixedly sleeved on the outer circular wall of the outlet of the submersible pump 19, and the drain pipe 20 is fixedly sleeved with the fixing hole 17. Drain holes 31 are respectively formed on the top surfaces of the floating tank 4 and the support pipe 16. Outlet pipes 32 are fixedly sleeved on the inner circular walls of the two drain holes 31. The support pipe 16 is movably sleeved with the movable hole 10. When the buoyancy block 9 moves upward, it is restricted by the support pipe 16, allowing the buoyancy block 9 to rise smoothly. When the water level drops, the submersible pump 19 is used. After the submersible pump 19 is started, it will draw out the water inside the floating tank 4 and discharge it into the support pipe 16 through the drain pipe 20. Then the water inside the support pipe 16 will be discharged through the water outlet pipe 32, which facilitates the drop of the water level inside the floating tank 4, allowing the buoyancy block 9 to move down naturally. A fixing ring 23 is fixedly installed on one side of the sliding frame 3. A float level sensor 24 is fixedly sleeved on the inner circular wall of the fixing ring 23. The float level sensor 24 is electrically connected to the PLC controller.

[0024] Example 3: Based on Example 1 or 2 above, refer to Figure 1 , Figure 2 and Figure 4 Two buffer grooves 25 are opened on one side of the sliding frame 3. A fixing block 26 is fixedly installed on the outer circular wall of the rubber fender body 2. Two buffer columns 27 are fixedly installed on one side of the fixing block 26. The buffer columns 27 are movably connected to the buffer grooves 25. A spring 28 is movably connected to the outer circular wall of the buffer column 27. The two ends of the spring 28 are fixedly installed to the fixing block 26 and one side of the sliding frame 3, respectively. Through the buffer columns 27, when the hull contacts the rubber fender body 2, the rubber fender body 2 will be squeezed, which will drive the fixing block 26 and the buffer column 27 to move and compress the spring 28, thereby reducing the impact force on the rubber fender body 2. A moving hole 29 is opened on the top surface of the sliding frame 3. A stabilizing column 30 is fixedly installed inside the mounting frame 1. The stabilizing column 30 is movably connected to the moving hole 29. Several air cushions 12 are fixedly installed on the outer circular wall of the rubber fender body 2.

[0025] Working principle: Please refer to Figures 1-7As shown, by using the submersible solenoid valve 21, the mounting bracket 1 and the rubber fender body 2 are placed in the water, so that most of the area of ​​the mounting bracket 1 and the rubber fender body 2 remains above the water surface. When the water level rises, by using the submersible solenoid valve 21, which is located at the bottom of the floating tank 4 and below the water surface, water will flow into the interior of the floating tank 4 through the submersible solenoid valve 21. The increase in water inside the floating tank 4 will cause the buoyancy block 9 to float. At this time, the buoyancy block 9 will move along with the water flowing into the floating tank 4. As the buoyancy block 9 rises, it will cause the U-shaped frame 11 and the magnet 13 to move. Since the magnet 13 and the magnet 15 are attached together, when the buoyancy block 9, the U-shaped frame 11 and the magnet 13 move upward, the magnet 13 will drive the magnet 15, the sliding frame 3 and the rubber fender body 2 to move upward. This will keep the air cushion 12 at the water surface as the water level rises, preventing the fender from failing to play its proper buffering role when the water level rises to submerge the fender, thus preventing the ship from directly hitting the dock and increasing the risk of damage to the hull and the dock.

[0026] With the support pipe 16 in place, when the buoyancy block 9 moves upward, it can rise steadily due to the restriction of the support pipe 16. When the water level drops, the submersible pump 19 is used. After the submersible pump 19 is started, it will draw out the water inside the floating tank 4 and discharge it into the support pipe 16 through the drain pipe 20. Then the water inside the support pipe 16 will be discharged through the outlet pipe 32, which will facilitate the drop of the water level inside the floating tank 4 and allow the buoyancy block 9 to move downward naturally.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
