Description
Technical Field
[0001] The utility model relates to the technical field of ships and ports, in particular to an anti-collision protection device for ships entering ports. Background Art
[0002] Ship is a general term for various vessels. Ships are vehicles that can sail or anchor in waters for transportation or operations. They have different technical performance, equipment and structural types according to different usage requirements.
[0003] The known authorized patent with application number: CN202320722251.5 discloses a port anti-collision device, which specifically relates to the field of port technology, including: a support plate, a plurality of fixing frames are installed on the side wall of the support plate, an anti-collision roller is rotatably connected to the inner side of the fixing frame, and a buffer assembly is arranged between the fixing frame and the support plate; the buffer assembly includes a plurality of sliding cavities opened on the side wall of the support plate and a connecting plate installed on one side of the fixing frame facing the sliding cavity, wherein two sliders are symmetrically arranged inside the sliding cavity, a spring is fixed between the two sliders, and one end of the slider extends outside the sliding cavity. The utility model can form a buffer assembly through structures such as connecting rods, sliders, sliding cavities and springs. When a ship collides with an anti-collision roller, the buffering action of the buffer assembly can further reduce the collision impact between the ship and the anti-collision roller, thereby effectively avoiding the anti-collision roller from being broken and damaged, greatly improving the safety of the device when in use.
[0004] However, in the implementation of relevant technologies, it was found that the above technical solution has the following problems: it is not convenient to adjust the active stroke and elastic strength of the spring when in use. Most of the existing ship port anti-collision devices currently use springs or rubber rollers for buffering protection. During use, the rubber rollers are easily damaged and affect their use. The above solution uses springs to buffer the impact on the rubber roller, but its spring coefficient is fixed and cannot be adjusted. The elastic coefficient of the spring will gradually weaken after long-term use, thereby reducing the service life and effect of the device. Utility Model Content

[0011] Furthermore, the rotating mechanism includes a bidirectional screw rotatably connected between the two ends of the inner wall of the hydraulic cylinder, and a plurality of guide strips fixedly mounted on the inner wall of the hydraulic cylinder. Two pistons are symmetrically threadedly connected to the surface of the bidirectional screw and slidably connected to the guide strips.

[0018] The protective mechanism contacts the ship for initial protection, and after being subjected to force, it drives the slider to move closer to squeeze the buffer spring. Under the action of the buffer spring, the shock-absorbing impact force is further buffered. When the elasticity of the buffer spring weakens, the rotating mechanism drives the second piston closer, and the hydraulic oil is squeezed into the buffer cylinder through the connecting pipe, and the limit rod and piston one are pushed toward the cylinder, so that the piston squeezes the buffer spring, and then the active stroke and elastic strength of the buffer spring are adjusted, which avoids the situation where the elastic coefficient of the buffer spring is fixed and the buffer effect is weakened due to long-term use, which affects the use, prolongs the service life of the device, and effectively improves the use effect and flexibility of the device.

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figure 1 - Figure 4 , a ship entering a port anti-collision protection device, comprising: a fixing plate 1, a mounting plate 2 is fixedly mounted on one side of the fixing plate 1, and a buffer cylinder 3 is fixedly mounted on one side of the inner wall of the mounting plate 2;
[0027] A hydraulic cylinder 4 is fixedly mounted on the surface of the buffer cylinder 3, a connecting pipe 5 connected to the buffer cylinder 3 is fixedly mounted at the center of the surface of the hydraulic cylinder 4, and a valve is provided on the surface of the connecting pipe 5;
[0028] A rotating mechanism is provided in the hydraulic cylinder 4, and two pistons 2 13 are symmetrically provided on the surface of the rotating mechanism. Cylinders 6 are fixedly installed on both sides of the inner wall of the mounting plate 2. A limit rod 7 is slidably connected in the cylinder 6. One end of the limit rod 7 extends into the buffer cylinder 3 and is fixedly connected to a piston 1 8 that fits the inner wall of the buffer cylinder 3. A limit piece is provided in the buffer cylinder 3.
[0029] The surface of the limit rod 7 is slidably connected with a slider 10 that contacts the cylinder 6. The surface of the limit rod 7 is sleeved with a buffer spring 9, and the two ends of the buffer spring 9 are respectively connected to the piston 8 and the slider 10;
[0030] A protection mechanism is movably connected to one side of the slider 10 , and a limiting mechanism is provided between the protection mechanism and the fixing plate 1 .
[0031] When in use, the fixing plate 1 is installed in the use position. When the ship enters the port and contacts the protection mechanism, the protection mechanism can play a certain buffering role to prevent the ship's hull from being scratched, and the protection mechanism is forced to drive the two sliders 10 to move relatively along the surface of the limit rod 7 to squeeze the buffer spring 9. Under the action of the buffer spring 9, the effect of further buffering the shock-absorbing impact force is achieved to avoid damage to the protection mechanism caused by excessive force. When the elastic strength of the buffer spring 9 is weakened after long-term use, the valve on the connecting pipe 5 is opened, and the rotating mechanism is rotated to drive the two pistons 13 to move closer, so that the hydraulic pressure between the two The oil is squeezed into the buffer cylinder 3 through the connecting pipe 5. As the amount of hydraulic oil squeezed in, the two limit rods 7 and the piston 8 are pushed away from each other and move into the cylinder 6, so that the piston 8 squeezes one end of the buffer spring 9. The slider 10 cooperates with the cylinder 6 to limit the other end of the buffer spring 9, thereby achieving the effect of adjusting the active stroke and elastic strength of the buffer spring 9, avoiding the situation where the elastic coefficient of the buffer spring 9 is fixed and the buffer effect weakens due to long-term use, affecting the use, extending the service life of the device, facilitating the adjustment of the buffer strength according to the ship model and impact force, and effectively improving the use effect and flexibility of the device.
[0032] Preferably, the extrusion mechanism includes a bidirectional screw 11 rotatably connected between the two ends of the inner wall of the hydraulic cylinder 4 , a plurality of guide strips 12 fixedly mounted on the inner wall of the hydraulic cylinder 4 , and two pistons 13 symmetrically threadedly connected to the surface of the bidirectional screw 11 and slidably connected to the guide strips 12 .
[0033] The piston 13 fits the inner wall of the hydraulic cylinder 4, one end of the bidirectional screw 11 passes through the hydraulic cylinder 4 via a bearing and is fixedly connected to a rotating block, an oil filling pipe is fixedly installed on the surface of the hydraulic cylinder 4, and a sealing cap is threadedly connected to the end of the oil filling pipe.
[0034] Specifically, the bidirectional screw 11 is driven to rotate by rotating the rotating block, so that the two pistons 13 move closer to each other along the guide bar 12, and the hydraulic oil between the two pistons 13 is squeezed, so that the hydraulic oil is squeezed into the buffer cylinder 3 through the connecting pipe 5, so that the two pistons 1 8 are relatively far away from the adjusting buffer spring 9. By setting an oil filling pipe, it is convenient to inject hydraulic oil into the hydraulic cylinder 4.
[0035] Preferably, the limiting member is composed of two limiting rings 14 symmetrically fixedly mounted on the inner wall of the buffer cylinder 3 , and the limiting rings 14 are in contact with the piston 8 .
[0036] Specifically, by setting the limiting ring 14, the two pistons 8 in the initial state can be blocked and limited to prevent the two pistons 8 from contacting each other, thereby ensuring the distance between the two and facilitating the entry of hydraulic oil in the later stage.
[0037] Preferably, the protection mechanism comprises a connecting rod 15 symmetrically hinged on one side of the two sliders 10 , a U-shaped plate 16 hinged on the end of the connecting rod 15 , and a plurality of rubber rollers 17 rotatably connected between two sides of the inner wall of the U-shaped plate 16 .
[0038] A plurality of rubber protrusions are fixedly mounted on the surface of the rubber roller 17 , and the plurality of rubber protrusions are evenly distributed on the surface of the rubber roller 17 in the form of circular rings.
[0039] Specifically, when the ship contacts the rubber roller 17, the rubber roller 17 can provide a certain shock-absorbing and buffering effect, and drive the slider 10 to slide through the connecting rod 15 to squeeze and buffer the buffer spring 9. At the same time, the rubber roller 17 can rotate to facilitate guiding the movement of the ship, and the rubber protrusion can increase the friction between the rubber roller 17 and the ship, making the rubber roller 17 easier to rotate, so as to achieve the purpose of reducing the scratches on the ship and ensure the protection of the ship.
[0040] Preferably, the limiting mechanism comprises two groups of connecting blocks 18 fixedly mounted on the upper and lower sides of the U-shaped plate 16 and fixing rods 19 fixedly mounted on the upper and lower sides of the fixing plate 1 through base blocks and slidably connected to the connecting blocks 18 .
[0041] Specifically, when the U-shaped plate 16 is moved by collision, the connecting block 18 can be driven to slide along the surface of the fixing rod 19 , thereby achieving the purpose of enhancing the movement stability of the U-shaped plate 16 and ensuring the stability of the U-shaped plate 16 in use.
[0042] Working principle: When in use, install the fixing plate 1 in the use position. When the ship enters the port and contacts the protective mechanism, the protective mechanism can play a certain buffering role to prevent the ship's hull from being scratched, and the protective mechanism is driven by force to drive the two sliders 10 to move relatively along the surface of the limit rod 7 to squeeze the buffer spring 9. Under the reaction of the buffer spring 9, the effect of further buffering and shock-absorbing impact force is achieved to avoid damage to the protective mechanism caused by excessive force.
