Description

Technical Field

[0001] This invention relates to the field of dam collision prevention technology, specifically a multi-form dam collision prevention early warning system. Background Technology

[0002] Dikes are built on both sides of river channels, mainly to prevent floods and soil erosion. They are generally made of concrete, but some dikes are also made of earth and rock. When ships are navigating on the river for transportation, collisions with dikes often occur, especially in narrower waterways. After a collision, not only are the ships damaged and require repair, but the dikes are also structurally damaged, leading to a decrease in their flood resistance and a risk of collapse. Repairing them is undoubtedly time-consuming and labor-intensive.

[0003] Therefore, collision protection for dikes is essential, especially in areas prone to collisions. By deploying collision protection mechanisms on dikes, damage can be reduced, and passing vessels can be protected. For example, Chinese Patent Publication No. CN113931130A provides a multifunctional mechanical device for dike safety protection. A wave-damping plate is installed above the anchoring base, and the anchoring base and the wave-damping plate are rotatably connected via a rotating seat. A triangular auxiliary base is fixed to the rear side of the anchoring base. Elastic support mechanisms connected to the rear side of the wave-damping plate are equidistantly fixed on the inclined surface of the auxiliary base. Water resistance buffer mechanisms are fixed on both sides of the wave-damping plate, and a mechanical buffer mechanism is fixed to the rear side of the wave-damping plate. This invention is ingeniously designed and structurally sound. It utilizes water resistance to buffer the force of wave impacts or vessel collisions, effectively ensuring dike safety, extending dike service life, and offering advantages such as low cost and outstanding performance. It overcomes the shortcomings of spring buffers operating underwater and reduces maintenance costs.

[0004] While the aforementioned dam safety protection devices can effectively buffer collisions and ensure dam safety, we have found certain shortcomings in practical applications, such as:

[0005] The aforementioned safety protection devices for the dam are located underwater, making installation, maintenance, and replacement quite troublesome and requiring underwater operations by personnel. In addition, these protective devices can only serve as a buffer and cannot guide colliding vessels. Under normal circumstances, vessels do not collide with the dam directly, but rather at an acute angle. After the impact, they continue to travel along the dam. The aforementioned protective devices absorb all the impact force, which places high demands on the manufacturing materials. Moreover, after an impact, the lack of a guiding mechanism can cause the vessel to become stuck and suffer further damage.

[0006] Based on this, we propose a multi-form dam collision warning system. Summary of the Invention

[0007] (1) Technical problems to be solved

[0008] To address the shortcomings of existing technologies, this invention provides a multi-form dam collision warning system, which has the advantages of convenient installation and maintenance and the ability to decompose the impact force of ships.

[0020] As a preferred embodiment of the present invention, a hook is fixedly installed on the other side of the movable plate, and a passage groove for the hook to pass through is provided on the right side of the fixed cabinet.

[0021] The top of the movable plate is provided with a positioning groove, and the inner top wall of the fixed cabinet is provided with a through groove corresponding to the positioning groove.

[0022] As a preferred embodiment of the present invention, a vertical groove is provided at the center of the pontoon, and an installation groove is provided on the inner wall of the vertical groove;

[0023] It also includes a fixed bearing, the outer side of which is fixedly installed in the mounting groove, and the inner side is fixedly installed with a spline, which is slidably disposed in the spline groove, which is opened on the outer wall of the vertical rod.

[0024] As a preferred technical solution of the present invention, a submersible tank is anchored on the riverbed. A movable cavity is provided inside the submersible tank, and a piston is movably arranged inside the movable cavity. A connecting rod is fixedly installed on the right side of the piston. The end of the connecting rod extends to the outside of the submersible tank and is fixedly connected to a push plate. The push plate is used to prevent the vertical rod from swinging towards the dam.

[0025] As a preferred embodiment of the present invention, a positioning spring is sleeved on the connecting rod, and the positioning spring is fixedly disposed between the right side of the piston and the inner wall of the submersible tank.

[0030] (III) Beneficial Effects

[0031] Compared with the prior art, the present invention provides a multi-form dam collision avoidance and early warning system, which has the following beneficial effects:

[0032] 1. This multi-form dam collision warning system has pontoons on the vertical pole floating on the water surface. Before a ship collides with the dam, it will first hit the pontoons. The force on the pontoons causes the vertical pole to swing towards the dam, and then the impact force is buffered by the buffer mechanism to achieve the effect of protecting the dam.

[0033] 2. This multi-form dam collision warning system features buoys that can rotate on vertical poles. When impacted, the buoys can decompose the impact force of the vessel by rotating, dispersing the impact force towards the dam into a direction parallel to the dam, and simultaneously guiding the vessel to sail along the dam direction, further improving the protection effect of the dam. At the same time, it also reduces the material requirements for the buoys and other structures, saving costs.

[0034] 3. This multi-form dam collision warning system can be installed by fixing a mounting plate on the dam, which is convenient and simple to install, improves work efficiency, and can be operated on land without going into the water.

[0035] 4. This multi-form dam collision warning system features vertical poles, long plates, and elastic rods that can rotate with the gear shaft. When the vertical pole rotates to a horizontal position, it can be used as an "extension ladder," allowing workers to stand on it to inspect and maintain other adjacent collision warning systems (by rotating the vertical poles of other collision warning systems to a horizontal position) without having to go into the water.

[0036] 5. This multi-form embankment collision warning system features vertical poles, long plates, and elastic rods that can rotate with the gear shaft. When the vertical pole rotates to the upright position, it acts as a guardrail to prevent tourists from climbing over the embankment and protect the safety of people on the shore.

[0047] 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. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0048] Example 1:

[0049] Please see Figure 1 -

[0050] Figure 5 A multi-form dam collision warning system includes an installation plate 1, which is fixedly installed on the dam by several casting rods 2. Anti-loosening nuts are screwed on the casting rods 2 to prevent the installation plate 1 from loosening.

[0051] like Figure 2 As shown, two fixed seats 3 are arranged opposite each other at the end of the mounting plate 1 away from the dam. A gear shaft 4 is rotatably arranged between the two fixed seats 3. Both ends of the gear shaft 4 are provided with connecting parts 5. The long plate 7 is connected to the connecting parts 5 of the gear shaft 4 through an elastic rod 6. Several vertical rods 8 are evenly installed at the bottom of the long plate 7. Each vertical rod 8 is movably fitted with a float 9 that can float on the water surface.

[0052] In this embodiment, a toothed plate 10 meshes with the top surface of the toothed shaft 4, and a buffer mechanism is provided at the right end of the toothed plate 10. When the vertical rod 8 swings toward the dam, the buffer mechanism can provide buffering.

[0053] The buoy 9 on the vertical pole 8 floats on the water surface. Before the ship collides with the dam, it will hit the buoy 9 first. The force on the buoy 9 causes the vertical pole 8 to swing towards the dam, and then the impact force is buffered by the buffer mechanism to achieve the effect of protecting the dam.

[0054] like Figure 3As shown, the buffer mechanism specifically includes a movable plate 11, a fixed cabinet 12, a pressure plate 13, and a support spring 14. The movable plate 11 is fixedly installed on the right end of the toothed plate 10. The movable plate 11 is movably disposed inside the fixed cabinet 12. The fixed cabinet 12 is fixedly installed on the mounting plate 1. The pressure plate 13 is connected to the left inner wall of the fixed cabinet 12 through the support spring 14. The movable plate 11 is attached to the pressure plate 13, and the toothed plate 10 passes through the plate groove on the pressure plate 13.

[0055] When the buoy 9 is impacted, it causes the vertical rod 8 to swing toward the dam, which in turn drives the gear shaft 4 to rotate clockwise through the long plate 7 and the elastic rod 6. The clockwise rotation of the gear shaft 4 causes the gear plate 10 to move to the left. The leftward movement of the gear plate 10 pushes the pressure plate 13 to move through the moving plate 11, thereby compressing the support spring 14. The compression of the support spring 14 buffers the impact force.

[0056] In this embodiment, the elastic rod 6 has a certain deformability. Through the bending and deformation of the elastic rod 6, it can also buffer some of the impact force, especially the impact force from the side of the float 9.

[0057] like Figure 4 As shown, a hook 15 is fixedly installed on the other side of the movable plate 11, and a passage groove for the hook 15 to pass through is provided on the right side of the fixed cabinet 12.

[0058] The hook 15 connects to a traction mechanism, such as a hydraulic traction mechanism, which can pull the moving plate 11 to move. The moving plate 11 moves to the right, which drives the toothed plate 10 to move to the right. The toothed plate 10 moves to the right, which drives the toothed shaft 4 to rotate, thereby enabling the elastic rod 6, the long plate 7 and the vertical rod 8 to rotate clockwise.

[0059] When the vertical rod 8 is rotated to the position shown Figure 8 When in the horizontal position shown, the vertical bar 8 can be used as an "extension ladder". Workers can stand on the horizontal vertical bar 8 to inspect and maintain other adjacent collision warning systems (by rotating the vertical bars 8 of other collision warning systems to the horizontal position) without having to go into the water.

[0060] When the vertical rod 8 is rotated to the position shown Figure 9 When in the upright position shown, the vertical bar 8 can act as a guardrail to prevent tourists from climbing over the embankment and protect the safety of people on the shore. It has multiple usage forms.

[0061] In this embodiment, a positioning groove 16 is provided on the top of the movable plate 11, and a through groove 17 corresponding to the positioning groove 16 is provided on the inner top wall of the fixed cabinet 12. When the vertical rod 8 rotates to the position as shown in the figure, the positioning groove 16 is provided on the top of the movable plate 11, and the through groove 17 corresponding to the positioning groove 16 is provided on the inner top wall of the fixed cabinet 12. Figure 9 When the vertical rod 8 is in the upright position shown, the positioning groove 16 and the through groove 17 are aligned. At this time, bolts or rods can be inserted into the two grooves to maintain the upright position of the vertical rod 8 without the need for the traction mechanism to work continuously.

[0062] like Figure 5 As shown, a vertical groove is provided at the center of the float 9, and an installation groove 18 is provided on the inner wall of the vertical groove. It also includes a fixed bearing 19. The outer side of the fixed bearing 19 is fixedly installed in the installation groove 18, and a spline 20 is fixedly installed on the inner side. The spline 20 is slidably disposed in the flower groove 21. The flower groove 21 is opened on the outer wall of the vertical rod 8. The float 9 can move up and down on the vertical rod 8 (under the action of buoyancy) and can also rotate on the vertical rod 8 through the fixed bearing 19.

[0063] The pontoon 9 can rotate on the vertical rod 8. When it is impacted, the pontoon 9 can decompose the impact force of the ship by rotating, so that the impact force towards the dam is dispersed to a direction parallel to the dam, and at the same time guide the ship to sail along the dam, which further improves the protection effect of the dam. At the same time, the material requirements of the pontoon 9 and other structures are also lower, saving costs.

[0064] In this embodiment, the entire collision avoidance warning system can be installed by fixing the mounting plate 1 on the embankment. The installation is convenient and simple, which improves the work efficiency and eliminates the need for underwater operations.

[0065] Example 2:

[0066] Please see Figure 1 and Figure 6 Based on Embodiment 1, in this embodiment, a submersible tank 26 is anchored on the riverbed. A movable cavity 25 is provided inside the submersible tank 26. A piston 24 is movably arranged inside the movable cavity 25. A connecting rod 23 is fixedly installed on the right side of the piston 24. The end of the connecting rod 23 extends to the outside of the submersible tank 26 and is fixedly connected to a push plate 22. The push plate 22 is used to prevent the vertical rod 8 from swinging towards the dam.

[0067] like Figure 6 As shown, a positioning spring 27 is sleeved on the connecting rod 23. The positioning spring 27 is fixedly set between the right side of the piston 24 and the inner wall of the submersible tank 26. A rod groove 28 for the connecting rod 23 to pass through is opened on the right inner wall of the moving cavity 25. Fine holes 29 are evenly opened on the left inner wall of the moving cavity 25.

[0068] When the vertical rod 8 swings toward the dam due to the impact, its bottom end will push the push plate 22 to move. The movement of the push plate 22 will drive the piston 24 to move through the connecting rod 23. The movement of the piston 24 will compress the positioning spring 27 on the one hand, using the positioning spring 27 to buffer the impact force, and on the other hand, it will squeeze the water on the right side of the piston 24 out of the rod groove 28, using the small hole to release water, thereby achieving resistance and buffering.

[0069] In addition, when the piston 24 moves, water will also enter through the fine hole 29. The water entering through the fine hole 29 can also add resistance and achieve buffering, further improving the anti-collision effect.

[0070] Example 3:

[0071] Please see Figure 4 and Figure 7 Based on Embodiment 1, in this embodiment, a distance sensor 30 is installed on the side of the long plate 7 away from the dam. The output terminal of the distance sensor 30 is electrically connected to a controller, which controls the bulb 31 to light up. The bulb 31 is installed on the side of the toothed plate 10 away from the dam.

[0072] The distance sensor 30 can measure the distance between the ship and the dam. When the distance is too close, the distance sensor 30 sends a signal to the controller, and the controller controls the light bulb 31 to light up, thereby giving a warning and reminder to the staff on the ship to prevent them from crashing into the dam.

[0073] At night, bulb 31 can be kept on to provide illumination and reminders.

[0074] like Figure 4 As shown, a movable sleeve 32 is movably sleeved on the toothed plate 10, and a focusing cover 35 is fixedly installed on the movable sleeve 32. A transparent buffer shell 36 is provided at the opening of the focusing cover 35. The side of the movable sleeve 32 away from the dam is also connected to the wing plate 34 through a buffer spring 33. The wing plate 34 is fixedly installed on the toothed plate 10.

[0075] The light-focusing cover 35 can focus the light and improve the lighting effect. Before the ship hits the dam, it may first come into contact with the vertical rod 8. At this time, the tilt of the vertical rod 8 is used for buffering. It may also first come into contact with the transparent buffer shell 36. When it comes into contact with the transparent buffer shell 36 first, the transparent buffer shell 36 and the light-focusing cover 35 can be used for buffering. On the other hand, the force on the light-focusing cover 35 will also cause the movable sleeve 32 to move. The movement of the movable sleeve 32 stretches the buffer spring 33, which is used for buffering.

[0076] Furthermore, when the transparent buffer shell 36 is impacted, it not only moves itself but also pushes the toothed plate 10 to the right. The rightward movement of the toothed plate 10, via the toothed shaft 4, causes the vertical rod 8 to swing in the opposite direction to the dam. Figure 7 As shown, the pontoon 9 is tilted and fits the shape of the ship's bottom sidewall. At this time, the pontoon 9 will be attached to the sidewall of the ship's bottom, which will guide the movement of the ship, buffer the impact force, and provide a certain amount of reverse thrust to overcome the impact force of the ship, thereby further improving the anti-collision effect of the dam.

[0077] Although embodiments of the 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 invention, the scope of which is defined by the appended claims and their equivalents.
