Description

Technical Field

[0001] This invention relates to the field of port frontage protection technology, and more specifically, to a safety protection device for ports. Background Technology

[0002] A wharf is a transportation hub located along the waterway of a port, equipped with water-land intermodal transport facilities and conditions to allow ships to enter, exit, and berth safely. It serves as a gathering point and hub for ships, not only as a distribution center for industrial and agricultural products and foreign trade import and export goods, but also as a place for ships to berth, load and unload cargo, embark and disembark passengers, and replenish supplies.

[0003] To ensure the safety of ships berthing, existing berths install anti-collision plates along the quay wall at the berth's front edge. These plates protect ships during berthing and departure, as well as the quay wall itself. Currently, most anti-collision plates assembled at the quay wall are made of rubber, polyurethane, and other materials. While they can withstand the impact of ships berthing and departure, relying solely on the properties of these materials is clearly insufficient. Therefore, it is necessary to improve their buffering and protective effects.

[0004] Existing technology 1: An existing patent (publication number: CN216339338U) describes a safety protection device for port channels. This device uses a support plate, rollers, shock-absorbing rubber rings, a moving cylinder, and a rotating linkage. When a ship is moored on the side of the harbor, its side plate collides with the shock-absorbing rubber rings on the rollers. The rubber rings absorb shock, and as the rollers rotate, the ship experiences a deflection force, preventing damage to the ship's side plate and the harbor from collisions. However, while this protective device provides some shock absorption, it is directly bolted to the side, requiring drilling holes. This indirectly damages the integrity of the side slopes. Furthermore, once the holes are drilled and the assembly is fixed, the protective surface is fixed. If the position of the anti-collision plate needs to be changed later, new holes must be drilled, which is not user-friendly.

[0005] Prior Art 2: Existing patent (publication number: CN113006001A) discloses a safety protection device for port channels. It adds a self-rotating gas shock-absorbing auxiliary moving device, which utilizes the frictional force exerted on the self-rotating upper and lower airbags by the ship's forward movement to achieve self-rotation, thereby avoiding airbag rupture and protecting the safety of the ship and the port. Furthermore, its fixed end is set on the upper side of the port channel, which can avoid opening holes on the slope side to a certain extent and improve the integrity of the slope side.

[0006] In response to the problems existing in the prior art, both prior art one and prior art two provide solutions from different directions. Although prior art two can avoid drilling holes directly on the side to install brackets to assemble the anti-collision plate compared to prior art one, its integration is relatively high and cannot be adjusted after installation. Furthermore, the outer anti-collision plate is a vulnerable component, which means that port staff need to go into the water to inspect it during daily maintenance work, which is time-consuming, labor-intensive, and inefficient. Summary of the Invention

[0007] In view of the problems existing in the prior art, the purpose of the present invention is to provide a safety protection device for wharves, which solves the problem that the assembly end of the anti-collision plate of the wharf front wall has a high degree of integration and cannot be adaptively adjusted, resulting in low efficiency of daily maintenance work.

[0008] To solve the above problems, the present invention adopts the following technical solution.

[0009] A safety protection device for a dock includes a base plate, an external lifting mechanism is installed on the upper surface of the base plate, a lifting mechanism is installed at the output end of the external lifting mechanism, a tilt adjustment mechanism is installed on the outside of the lifting mechanism, and an octagonal inner partition is provided on the outside of the tilt adjustment mechanism. The outer surface of the octagonal inner partition is equipped with multiple second buffer sleeve mechanisms between the main anti-collision plate and the secondary anti-collision plate. The bottom of the inner wall of the lifting mechanism is equipped with a first buffer sleeve mechanism. The outer surface of the first buffer sleeve mechanism is equipped with a rubber pad that contacts the quay wall at the front edge of the wharf. The outer lifting mechanism and the lifting mechanism are connected by a movable hinge. The upper surface of the outer lifting mechanism is equipped with a recovery mechanism corresponding to the octagonal inner partition, which is used to pull the octagonal inner partition upward to rotate around the hinge end of the outer lifting mechanism, so that the main anti-collision plate and the secondary anti-collision plate are raised upward, so that the protective end can be directly inspected and repaired without going into the water.

[0010] Furthermore, the lifting mechanism includes lifting side plate frames fixedly connected to both sides of the rear upper surface of the base plate. An outward-folding plate is movably installed on the inner wall of the lifting side plate frame. A first U-shaped frame is fixedly installed at the bottom center of the outward-folding plate and at the center of the upper surface of the base plate. A corresponding electric telescopic rod is movably installed inside the center of the first U-shaped frame. The lifting mechanism includes a second U-shaped frame movably installed at the front end of the outward-folding plate. A nut sleeve frame is provided at the bottom of the second U-shaped frame.

[0011] Furthermore, a first servo motor is fixedly installed at the middle position of the upper surface of the second U-shaped frame, and a limit rod is fixedly connected to the bottom of the second U-shaped frame. A threaded rod is movably installed at the middle position of the limit rod.

The nut sleeve frame is slidably installed on the outside of the limit rod. A threaded opening corresponding to the threaded rod is provided at the middle position of the upper side of the nut sleeve frame. A square opening for accommodating the limit rod and the threaded rod is provided on the upper surface of the nut sleeve frame.

[0012] Furthermore, the tilt adjustment mechanism includes a clamping frame fixedly connected to the middle position of the outer surface of the nut sleeve frame. An outward-folding three-way frame is movably installed inside the clamping frame. An L-shaped double-layer outward-folding rod that penetrates the clamping frame is fixedly connected to the upper side of the rotation axis end face of the outward-folding three-way frame. The L-shaped double-layer outward-folding rod has a double-layer structure that can slide up and down. The tilt adjustment mechanism also includes an arc-shaped positioning plate fixedly installed at the middle position of the upper surface of the first servo motor. A plurality of first assembly openings are sequentially provided on the surface of the arc-shaped positioning plate. The outer side of the L-shaped double-layer outward-folding rod is attached to the upper surface of the arc-shaped positioning plate and is provided with corresponding openings and fastening bolts.

[0013] Furthermore, the outer surface of the base plate has a plurality of second assembly ports arranged in a circular pattern on the outer side. The upper surface of the winding turntable is fixedly connected to an expansion plate. The outer end of the expansion plate is provided with a third assembly port corresponding to the second assembly ports. A limiting rod corresponding to the second assembly port is inserted into the third assembly port. A hand crank is fixedly connected to the upper surface of the expansion plate.

[0014] Furthermore, the second buffer sleeve mechanism has the same structure as the first buffer sleeve mechanism. The first buffer sleeve mechanism includes a hollow cylinder fixedly connected to the bottom of the inner side of the nut sleeve frame. A return spring ring is fixedly connected at the axial position inside the hollow cylinder. A cross-shaped limiting groove is provided on the inner wall of the hollow cylinder. A cross-shaped sleeve plate is fixedly connected to the outer side of the return spring ring. The cross-shaped sleeve plate slides in correspondence with the cross-shaped limiting groove. A round-mouth cover plate is provided on the outside of the hollow cylinder. An outer push rod passing through the round-mouth cover plate is fixedly connected at the axial position on the surface of the cross-shaped sleeve plate.

[0015] Furthermore, an octagonal inner partition is fixedly connected to the outer surface of the outward-folding three-way frame. Multiple second buffer sleeve mechanisms are sequentially fixedly installed at the middle position and the left and right sides of the outer surface of the octagonal inner partition. A main anti-collision plate is fixedly installed on the outer surface of the second buffer sleeve mechanism in the middle of the outer side of the octagonal inner partition. A secondary anti-collision plate is fixedly installed on the outer surface of the second buffer sleeve mechanism on the left and right sides of the octagonal inner partition. The left and right sides of the main anti-collision plate and the corresponding secondary anti-collision plates are movably hinged. An anti-collision flashing mechanism is installed at the outer end of each secondary anti-collision plate.

[0016] Furthermore, the anti-collision strobe mechanism includes a warning cylinder fixedly connected to the side of the secondary anti-collision plate. The warning cylinder has a hollow internal structure and its outer surface has multiple open side grooves arranged in a circular pattern. A connecting rod sleeve is movably installed at the axial position inside the warning cylinder. Multiple octagonal partitions are fixedly installed in a circular pattern on the upper side of the connecting rod sleeve. Reflector plates are fixedly installed on the left and right inclined surfaces of the octagonal partitions. Stirring blades are fixedly installed at the bottom of the connecting rod sleeve.

[0017] Furthermore, multiple threaded sockets are provided at both ends of the front side of the base plate, and the interior of each threaded socket is used to install corresponding expansion screws.

[0018] Furthermore, a winding sleeve is fixedly installed at the middle position of the front side of the upper surface of the outward-folding plate. The winding sleeve is an integral winding rod structure, and an arc sleeve to prevent detachment is provided on the upper side of the winding rod end.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The rotating structure consisting of the lifting mechanism and the hoisting mechanism installed on the upper surface of the base plate can be used to protect the end of the device by rotating it upward around the lifting mechanism under the traction of the traction rope of the recovery mechanism, so that the whole device can be lifted off the water surface. During daily maintenance, the protective end can be inspected without the need for staff to go into the water, which reduces the amount of maintenance work and can also effectively improve the efficiency of daily maintenance and improve the safety of daily maintenance.

[0020] (2) By utilizing the movable hinge relationship between the outward flipping plate set by the external lifting mechanism and the second U-shaped frame of the lifting mechanism, during the assembly process, only the base plate needs to be fixed with bolts to lower the octagonal inner partition on the side for wharf protection through the flipping action. There is no need to open holes on the wharf front wall. This not only avoids the destruction of the integrity of the wharf front, but also allows the flexibility of its movable hinge to adapt to the wharf front wall with different slopes. Even if the wharf front wall is in an inclined state, one end of the octagonal inner partition can be attached to its side for protection, further improving the adaptability of the protection device.

[0021] (3) The first servo motor installed in the lifting mechanism can adjust the bottom nut sleeve frame according to the actual water depth of the water area in front of the dock by rotating the threaded rod at its output end. The protective end can be placed in a suitable position according to the needs and actual situation, so that the end face of the protective end can be adjusted according to the water depth at different times. Unlike the fixed protective end, it is not only more flexible and controllable, but also does not require repeated drilling and reassembly of the protective end to adapt to the water depth.

[0022] (4) By installing the corresponding first buffer sleeve mechanism and second buffer sleeve mechanism on the end of the inner wall of the nut sleeve frame that contacts the slope and the end that protects the outer surface of the octagonal inner partition, respectively, the overall anti-collision performance and buffer protection effect can be further improved. The multiple reset spring rings set at its front and rear ends can effectively increase the resistance and buffering capacity of its main anti-collision plate and secondary anti-collision plate when they come into contact with the ship.

[0023] (5) After the anti-collision strobe mechanism installed on the side of the secondary anti-collision plate, together with its lifting mechanism, lowers the whole device to a suitable position, its stirring blades can drive the connecting rod sleeve on the inner wall of the warning cylinder to rotate under the driving action of the water flow. By using its rotating octagonal partition to repeatedly display the reflector plate through the open side groove, the strobe effect can be automatically achieved, further improving the warning effect of the anti-collision end.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1 to 9A safety protection device for a dock includes a base plate 1, an external lifting mechanism 3 is installed on the upper surface of the base plate 1, a lifting mechanism 4 is installed at the output end of the external lifting mechanism 3, an angle adjustment mechanism 5 is installed on the outside of the lifting mechanism 4, and an octagonal inner partition 8 is provided on the outside of the angle adjustment mechanism 5. Among them, multiple second buffer sleeve mechanisms 10 are installed on the outer surface of the octagonal inner baffle 8 and between the main anti-collision plate 11 and the secondary anti-collision plate 12. A first buffer sleeve mechanism 6 is installed on the bottom of the inner wall side of the lifting mechanism 4. A rubber pad 7 that contacts the side of the channel slope is installed on the outer surface of the first buffer sleeve mechanism 6. The outer lifting mechanism 3 and the lifting mechanism 4 are connected by a movable hinge. A recovery mechanism 9 corresponding to the octagonal inner baffle 8 is installed on the upper surface of the outer lifting mechanism 3. It is used to pull the octagonal inner baffle 8 upward to rotate around the hinge end of the outer lifting mechanism 3, so that the main anti-collision plate 11 and the secondary anti-collision plate 12 are lifted upward, so that the protective end can be directly inspected without going into the water.

[0028] Regarding existing protective structures installed on the quay wall at the wharf's edge, they are either directly installed on the sides of the slopes, resulting in varying numbers of assembly openings on both sides, affecting the integrity of the slopes; or integrated safety protection devices are installed on the upper side of the slopes, which, while eliminating the need for openings on the water-contact surface, offers limited overall controllability and adjustability. Furthermore, as mentioned earlier, the layout of the navigation channel axis is complex and variable, making it difficult for fixed-position crash barriers to adapt to different environments. Moreover, crash barriers are generally made of materials such as rubber and polyurethane, which require adjustments during daily operation. Regular maintenance is required, and the fixed position of the anti-collision plate, which cannot be adapted to adjustment, necessitates staff to go into the water for maintenance, which is time-consuming and labor-intensive. Therefore, the above-mentioned technical solution is needed to enable direct maintenance of the protective end without going into the water. First, by utilizing the movable hinge relationship between the outer lifting mechanism 3 and the lifting mechanism 4, it can rotate upward under the pulling action of the recovery mechanism 9, raising the outer main anti-collision plate 11 and the secondary anti-collision plate 12 used for protection. This allows for direct maintenance of the protective end on the shore without going into the water. Furthermore, its flip-over design can adapt to port channels in different environments, i.e., slopes with different inclinations.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6As shown, the lifting mechanism 3 includes a lifting side plate frame 31 fixedly connected to both sides of the rear of the upper surface of the base plate 1. An outward-folding plate 32 is movably installed on the inner wall of the lifting side plate frame 31. A first U-shaped frame 33 is fixedly installed at the bottom center of the outward-folding plate 32 and at the center of the upper surface of the base plate 1. A corresponding electric telescopic rod 34 is movably installed inside the first U-shaped frame 33. The lifting mechanism 4 includes a second U-shaped frame 41 movably installed at the front end of the outward-folding plate 32. A nut sleeve frame 45 is provided at the bottom of the second U-shaped frame 41. The first buffer sleeve mechanism 6... The recycling mechanism 9 is fixedly installed at the bottom of the inner wall of the nut sleeve frame 45. It includes a base plate 91 fixedly installed at the middle of the rear side of the upper surface of the outward-turning plate 32. A winding turntable 93 is movably installed on the upper surface of the base plate 91. A traction rope 98 is wound on the outer surface of the winding turntable 93. The recycling mechanism 9 also includes a third U-shaped frame 99 fixedly connected to the middle of the upper surface of the octagonal inner partition 8. A rotating drum block 910 is movably installed inside the third U-shaped frame 99. The end of the traction rope 98 away from the winding turntable 93 is fixedly connected to the outer side of the rotating drum block 910.

[0030] As described in the previous embodiments, the integrated protective end cannot adapt to the complex quay front wall. Therefore, it is necessary to improve it by adopting the above-mentioned technical solution. First, according to the protection requirements of the channel axis, corresponding base plates 1 are installed at certain intervals at the corresponding positions on the slope. According to the installation position and the inclination angle of the slope, the outer lifting mechanism 3 is opened to unfold the protective device outward. That is, through the electric telescopic rod 34, the outer flip plate 32 is controlled to lift and rotate upward around the inner wall of the lifting side plate frame 31, so that the lifting side plate frame 31 lowers the lifting mechanism 4 at the most suitable angle. Since the second U-shaped frame 41 of the lifting mechanism 4 and the outer flip plate 32 are in a movable hinge relationship, the nut sleeve frame 45 at the bottom of the second U-shaped frame 41 will move inward due to gravity, so that the nut sleeve frame 45 inside The first buffer sleeve mechanism 6 and the rubber pad 7 on the side of the wall automatically fit against the side of the slope. When the water level in the channel is high, the electric telescopic rod 34 of the outer lifting mechanism 3 can also lift the side plate frame 31 upward, so that the flip end of the second U-shaped frame 41 of the lifting mechanism 4 can be lifted upward, thereby lifting the entire protective end. In subsequent maintenance, it is only necessary to rotate the winding turntable 93 of the recovery mechanism 9 to rewind the extended traction rope 98 through the winding turntable 93. During the winding process, the octagonal inner partition 8 will slowly flip upward at the hinge end of the second U-shaped frame 41 and the outer flip plate 32, so that the main anti-collision plate 11 and the secondary anti-collision plate 12 on the outside of the octagonal inner partition 8 can flip upward and leave the water surface to approach the shore, which is convenient for on-site personnel to carry out maintenance and management. The protective end can be directly inspected on the shore without going into the water.

[0031] like Figure 4 , Figure 5 , Figure 6 As shown, a first servo motor 42 is fixedly installed at the middle position of the upper surface of the second U-shaped frame 41. A limiting rod frame 43 is fixedly connected to the bottom of the second U-shaped frame 41. A threaded rod 44 is movably installed at the middle position of the limiting rod frame 43. The bottom output end of the first servo motor 42 passes through the surface of the second U-shaped frame 41 and is fixedly connected to the threaded rod 44. The nut sleeve frame 45 is slidably installed on the outside of the limiting rod frame 43. A threaded opening corresponding to the threaded rod 44 is provided at the middle position of the upper side of the nut sleeve frame 45. A square opening for accommodating the limiting rod frame 43 and the threaded rod 44 is provided on the upper surface of the nut sleeve frame 45.

[0032] As described in the previous embodiment, the protective end needs to be adaptively adjusted according to the water level. Although the position of the protective end can be changed by lifting the rotating end upward with the lifting action of the lifting mechanism 3, if the water level is too low, it is difficult to adjust the position again by lifting angle. Therefore, it is necessary to use the above-mentioned technical solution for lifting adjustment. By rotating the threaded rod 44 at the output end of the first servo motor 42 mounted on the surface of the second U-shaped frame 41, the nut sleeve frame 45 is driven to move synchronously up and down along the second U-shaped frame 41, so as to further control the height of the outer side of the nut sleeve frame 45.

[0033] like Figure 1 , Figure 5 , Figure 6 As shown, the tilt adjustment mechanism 5 includes a clamping frame 51 fixedly connected to the middle position of the outer surface of the nut sleeve frame 45. An outward-folding three-way frame 52 is movably installed inside the clamping frame 51. An L-shaped double-layer outward-folding rod 53 that penetrates the clamping frame 51 is fixedly connected to the upper side of the rotation axis end face of the outward-folding three-way frame 52. The L-shaped double-layer outward-folding rod 53 is a double-layer structure that can slide up and down. The tilt adjustment mechanism 5 also includes an arc-shaped positioning plate 54 fixedly installed at the middle position of the upper surface of the first servo motor 42. A plurality of first assembly ports 55 are sequentially provided on the surface of the arc-shaped positioning plate 54. The outer side of the L-shaped double-layer outward-folding rod 53 is attached to the upper surface of the arc-shaped positioning plate 54 and is provided with corresponding openings and fastening bolts 56.

[0034] As described in the aforementioned embodiments, sufficient safety distance has been reserved in the waters in front of the wharf according to the design of the ship type. However, in actual berthing, the ship is not always parallel to the wharf's quay wall. Especially when large ships berth with the assistance of tugboats, there is a certain angle between the ship's side and the quay wall. Therefore, it is necessary to adjust the orientation of the protective plate according to the ship's angle during berthing. Thus, the above-mentioned technical solution is adopted to loosen the fastening bolts 56 fixed to the upper side of the L-shaped double-layer outward-turning rod 53, so that the L-shaped double-layer outward-turning rod 53 can rotate. During the rotation, the outward-turning three-way frame 52 on the inner wall of the clamping frame 51 rotates synchronously, thereby changing its outward-turning three-way frame 52. The orientation of the octagonal inner partition 8 on the outer surface of the frame 52 is adjusted to change the tilt position of the main anti-collision plate 11 and the secondary anti-collision plate 12. Since the arc-shaped positioning plate 54 is arc-shaped and its arc axis is the same as the center of the clamping plate 51, the L-shaped double-layer outward flipping rod 53 can smoothly drive the outward flipping three-way frame 52 to rotate by rotating along the arc-shaped positioning plate 54. The positioning and fixing can be achieved by installing the fastening bolt 56 in the first assembly port 55 on the corresponding side. The L-shaped double-layer outward flipping rod 53 is a double-layer square rod that can be pulled up and down. When the threaded rod 44 of the lifting mechanism 4 drives the whole to lift and adjust, it can adaptively extend and retract to avoid movement interference.

[0035] like Figure 1 , Figure 7 As shown, the outer side of the upper surface of the base plate 91 is provided with a plurality of second assembly ports 92 arranged in a circular pattern. The upper surface of the winding turntable 93 is fixedly connected to an expansion plate 94. The outer end of the expansion plate 94 is provided with a third assembly port 95 corresponding to the second assembly ports 92. A limiting rod 96 corresponding to the second assembly port 92 is inserted into the third assembly port 95. A hand crank 97 is fixedly connected to the upper surface of the expansion plate 94.

[0036] As described in the previous embodiment, in order to rotate and lift the protective end upward, it is necessary to rotate the winding turntable 93 to wind the wire. However, it is impossible to fix the already tightened traction rope 98 during the winding process. Therefore, it is necessary to use the above-mentioned technical solution to fix the traction rope 98. First, the third assembly port 95 on the outer expansion plate 94 on the upper surface of the winding turntable 93 corresponds vertically to the second assembly port 92. When the winding turntable 93 rotates to a certain angle, that is, when the wire is wound to a certain extent, the limiting plug 96 can be inserted into the third assembly port 95 and the second assembly port 92 at the corresponding position to fix the winding turntable 93. Once the winding turntable 93 is fixed, the traction rope 98 is fixed to a certain length. During the rotation process, it can be rotated by the hand crank 97.

[0037] like Figure 1 , Figure 5 , Figure 6 , Figure 8As shown, the second buffer sleeve mechanism 10 has the same structure as the first buffer sleeve mechanism 6. The first buffer sleeve mechanism 6 includes a hollow cylinder 61 fixedly connected to the bottom of the inner side of the nut sleeve frame 45. A return spring coil 62 is fixedly connected at the axial position inside the hollow cylinder 61. A cross-shaped limiting groove 63 is provided on the inner wall of the hollow cylinder 61. A cross-shaped sleeve plate 65 is fixedly connected to the outer side of the return spring coil 62. The cross-shaped sleeve plate 65 slides in correspondence with the cross-shaped limiting groove 63. A round-mouth cover plate 64 is provided on the outside of the hollow cylinder 61. An outer push rod 66 passing through the round-mouth cover plate 64 is fixedly connected at the axial position on the surface of the cross-shaped sleeve plate 65.

[0038] As ships enter the port and prepare to berth, they are affected by waves and sway, which can cause them to collide with the quay wall. The main and secondary anti-collision plates 11 and 12 alone are insufficient to buffer the reaction force, necessitating the aforementioned technical solution for buffering protection. The first buffer sleeve mechanism 6 and the second buffer sleeve mechanism 10 have the same structure, using multiple hollow cylinders 61 in conjunction with a return spring coil 62 to resist the reaction force. The return spring coil 62, when not under stress, is... In the unfolded state, the outer push rod 66 is pushed outward through the round cover plate 64. When the ship approaches the main anti-collision plate 11 and the secondary anti-collision plate 12, its return spring ring 62 begins to be stressed for buffering. During the buffering process, it is limited by the cavity of the cavity cylinder 61 and the cross limit groove 63 to ensure that the cross sleeve plate 65 at the bottom of the outer push rod 66 is stably retracted. The return spring ring 62 on the inner wall of its nut sleeve frame 45 and the multiple return spring rings 62 on the outer side of the octagonal inner partition plate 8 work together to effectively increase the overall protective buffering performance of the device.

[0039] like Figure 1 , Figure 4 , Figure 5 As shown, an octagonal inner partition 8 is fixedly connected to the outer surface of the outward-folding three-way frame 52. Multiple second buffer sleeve mechanisms 10 are sequentially fixedly installed at the middle position and the left and right sides of the outer surface of the octagonal inner partition 8. A main anti-collision plate 11 is fixedly installed on the outer surface of the second buffer sleeve mechanism 10 at the middle outer side of the octagonal inner partition 8. A secondary anti-collision plate 12 is fixedly installed on the outer surface of the second buffer sleeve mechanism 10 on the left and right sides of the octagonal inner partition 8. The left and right sides of the main anti-collision plate 11 and the corresponding end of the secondary anti-collision plate 12 are movably hinged. An anti-collision flashing mechanism 13 is installed at the outer end of the secondary anti-collision plate 12.

[0040] like Figure 1As shown, the anti-collision strobe mechanism 13 includes a warning cylinder 131 fixedly connected to the side of the secondary anti-collision plate 12. The interior of the warning cylinder 131 is a hollow structure and its outer surface is provided with multiple open side grooves 132 arranged in a circular pattern. A connecting rod sleeve 133 is movably installed at the axial position inside the warning cylinder 131. Multiple octagonal partitions 134 are fixedly installed in a circular pattern on the upper side of the connecting rod sleeve 133. Reflector plates 135 are fixedly installed on the left and right inclined surfaces of the octagonal partitions 134. Stirring blades 136 are fixedly installed at the bottom of the connecting rod sleeve 133.

[0041] Unlike the single-piece anti-collision plates in the prior art, the outer surface of the octagonal inner partition 8 is equipped with a secondary anti-collision plate 12 and a primary anti-collision plate 11 on the left and right sides and the middle side, respectively. The primary anti-collision plate 11 and the secondary anti-collision plate 12 are hinged to each other, making its anti-collision more flexible. By adopting the above technical solution, the anti-collision strobe mechanism 13 on the side of the secondary anti-collision plate 12 can automatically flash, further improving its protective effect, especially at night, which can greatly improve its warning effect. The stirring blade 136 rotates under the driving force of the water flow. During the rotation, it can drive the connecting rod sleeve 133 to rotate synchronously. During the rotation of the connecting rod sleeve 133, the reflector plates 135 on the inclined surfaces on both sides of the octagonal partition 134 can rotate around the axis of the warning cylinder 131. Since the surface of the warning cylinder 131 is provided with multiple open side grooves 132, the reflector plates 135 will form a strobe warning by rotating through the open side grooves 132, which can effectively alert passing ships at night.

[0042] like Figure 1 As shown, multiple threaded sockets 2 are provided at both ends of the front side of the base plate 1, and the interior of each threaded socket 2 is used to install corresponding expansion screws.

[0043] like Figure 1 As shown, a winding sleeve 911 is fixedly installed at the middle position of the front side of the upper surface of the outward-folding plate 32. The winding sleeve 911 is a winding rod structure, and an arc sleeve to prevent detachment is provided on the upper side of the winding rod end.

[0044] The arc sleeve on the upper side of its winding reel 911 is used to prevent the traction rope 98 from detaching upwards.

[0045] Instructions for use: First, install the base plate 1 into the corresponding position through the threaded sleeve 2 according to the arrangement requirements. Then, through the lifting action of the external lifting mechanism 3 and the lifting action of the lifting mechanism 4, the nut sleeve frame 45 can be transported to the corresponding position. Afterward, simply raise the winding turntable 93 of the rotating recovery mechanism 9 and retract the traction rope 98 to pull back the octagonal inner partition 8, so that the outer main anti-collision plate 11 and the secondary anti-collision plate 12 automatically move upward and closer together. The protective end can be inspected and repaired directly on the shore without going into the water.

[0046] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
