Ship wave energy dissipation device suitable for ecological channel

Abstract

This utility model discloses a wave energy dissipation device suitable for ecological waterways, specifically relating to the technical field of wave dissipation equipment for waterways. It includes a stress-relief component installed on the front side of a fixed plate for wave energy elimination. The stress-relief component includes a support plate installed on the front side of the fixed plate via a support member, and a movable plate is provided on the rear side of the support plate. This utility model designs the movable plate and support plate as arc-shaped, allowing the arc surface to convert the kinetic energy of the water flow into potential energy in the vertical direction. By changing the direction of the water flow, a reverse flow is formed, thereby reducing the positive impact force of the waves. The movable plate dissipates wave energy through the elastic deformation of a spring. Energy dissipation is achieved through dynamic displacement. Simultaneously, the rearward movement of the movable plate creates a gap between it and the support plate, forming a narrow channel. This allows the water flow to reflect multiple times within the gap, consuming energy. Thus, a three-stage energy dissipation mechanism forms an energy attenuation chain, improving the energy dissipation of ship waves.

Description

Technical Field

[0001] This utility model relates to the technical field of wave dissipation equipment for waterways, and more specifically to a wave energy dissipation device suitable for ecological waterways. Background Technology

[0002] With the rapid development of the global shipping industry, the density and tonnage of ship traffic have increased significantly, and the impact of ship waves on the ecological environment of waterways has become increasingly prominent. Ship waves are periodic waves formed by the compression of water by ships during navigation. When these waves propagate to both sides of the waterway, they can cause problems such as riverbank erosion, destruction of aquatic vegetation, and disturbance of benthic habitats. In particular, they can cause irreversible ecological damage to ecologically sensitive waterways (such as wetlands and fish spawning grounds). Therefore, it is necessary to implement energy dissipation measures for ship waves to reduce their interference with water flow and biological habitats.

[0003] As shown in the prior art published in CN218116324U, although this prior art achieves efficient concentration of water surface wave energy through the cooperation between the rotating rod, the wave-damping rod, the wave-damping float, and the left and right wave-damping springs, and through the limiting function of the wave-damping rod on the wave-damping float and the special structure of the wave-damping float, and simultaneously achieves a preliminary wave energy elimination function through the interaction between the elastic force of the left and right wave-damping springs and the wave energy, the wave energy elimination function of this technical solution is relatively low, only able to eliminate wave energy once, and the wave energy elimination effect is poor. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, this utility model provides a ship wave energy dissipation device suitable for ecological waterways, which can effectively solve the problem that the wave energy cannot be effectively eliminated due to the low energy dissipation efficiency in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wave energy dissipation device suitable for ecological waterways, comprising a force-dissipating component installed on the front side of a fixed plate for wave energy dissipation;

[0006] The unloading component includes a support plate installed on the front side of the fixed plate via a support member. A movable plate is provided on the rear side of the support plate. A contact plate for absorbing wave impact is installed on the front side of the bottom end of the movable plate. The movable plate is mounted on the front side of the fixed plate via two sets of buffer members.

[0007] Both the support plate and the movable plate are arc-shaped, with the front side of the movable plate fitting against the rear side of the support plate.

[0008] In a preferred embodiment, the support includes two pillars installed on the rear side of the support plate. The rear ends of the pillars pass through the movable plate and are bolted to the front side of the fixed plate. The pillars provide fixed support for the support plate, ensuring its stability.

[0009] In a preferred embodiment, each set of buffer components includes an encapsulation cylinder mounted on the front side of the fixed plate, and the encapsulation cylinder is connected to the fixed plate by bolts.

[0010] The encapsulation cylinder is equipped with a positioning post and a spring from front to back. A connecting rod that penetrates the encapsulation cylinder is installed at the front end of the positioning post, and the front end of the connecting rod is fixed to the rear side of the movable plate. The positioning post and the connecting rod are connected to the movable plate, and the impact force is buffered by the elastic deformation of the spring.

[0011] In a preferred embodiment, the diameter of the positioning post is equal to the inner diameter of the packaging cylinder, and the diameter of the connecting rod is smaller than the inner diameter of the packaging cylinder. Because the diameter of the positioning post is larger than the inner diameter of the packaging cylinder, and the diameter of the connecting rod is smaller than the inner diameter of the packaging cylinder, the positioning post can limit the connecting rod, preventing the connecting rod from separating from the packaging cylinder during the displacement process and ensuring the displacement stability of the connecting rod.

[0012] In a preferred embodiment, an assembly ring is sleeved on the front end of the connecting rod, and a sealing tube is threaded onto the outside of the assembly ring. The rear end of the sealing tube is sleeved on the front end of the encapsulation cylinder. The sealing tube protects the connecting rod from direct impact, thus ensuring the performance of the connecting rod.

[0013] In a preferred embodiment, the rear end of the spring is provided with a sealing post that is threadedly connected to the sealing cylinder, and an operating groove is provided on the rear side of the sealing post for easy rotation. The sealing post seals the rear end of the sealing cylinder, and the threaded connection between the sealing post and the sealing cylinder makes it easy to rotate the sealing post to disassemble and replace the spring.

[0014] The technical effects and advantages of this invention are as follows: By designing the movable plate and the support plate as arcs, the arc surface can convert the kinetic energy of the water flow into potential energy in the vertical direction. The change in water flow direction creates a reverse flow, thereby reducing the forward impact force of the waves. The movable plate dissipates wave energy through the elastic deformation of the spring, thus achieving energy dissipation through dynamic displacement. Simultaneously, the rearward movement of the movable plate creates a gap and a narrow channel between it and the support plate. This causes turbulence and vortices to form as the water flows through, and multiple reflections within the gap dissipate energy. This three-stage energy dissipation mechanism forms an energy attenuation chain, improving the energy dissipation effect on ship waves. Attached Figure Description

[0022] 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.

[0023] Refer to the instruction manual appendix Figure 1-5 This utility model provides a wave energy dissipation device suitable for ecological waterways, including a stress-relief component installed on the front side of a fixed plate 1 for wave energy dissipation; the stress-relief component includes a support plate 2 installed on the front side of the fixed plate 1 via a support member, a movable plate 3 provided on the rear side of the support plate 2, and a contact plate 4 for absorbing wave impact installed on the front side of the bottom end of the movable plate 3; the movable plate 3 is mounted on the front side of the fixed plate 1 via two sets of buffer members; both the support plate 2 and the movable plate 3 are arc-shaped, and the front side of the movable plate 3 is attached to the rear side of the support plate 2.

[0024] When using the above structure to deflect wave energy, the support includes two pillars 5 installed on the rear side of the support plate 2. The rear end of the pillars 5 passes through the movable plate 3 and is bolted to the front side of the fixed plate 1. Thus, the support plate 2 can be fixedly supported by the pillars 5 to ensure the stability of the support plate 2, so that the support plate 2 can withstand the impact of the waves. Since both the movable plate 3 and the support plate 2 are arc-shaped, when the waves impact the support plate 2, the arc surface converts the kinetic energy of the water into potential energy in the vertical direction, and forms a reverse water flow by changing the direction of the water flow. This can directly reduce the positive impact force of the waves and achieve the purpose of the first wave energy consumption.

[0025] Each set of buffer components includes an encapsulation cylinder 6 installed on the front side of the fixed plate 1, and the encapsulation cylinder 6 is connected to the fixed plate 1 by bolts. Inside the encapsulation cylinder 6, from front to back, there are positioning posts 7 and springs 8. The surface of the springs 8 can be sprayed with an epoxy resin anti-rust layer. The front end of the positioning post 7 is equipped with a connecting rod 9 that penetrates the encapsulation cylinder 6, and the front end of the connecting rod 9 is fixed to the rear side of the movable plate 3, so that the movable plate 3 moves backward along the axial direction under wave pressure, and applies pressure to the springs 8 by means of the connecting rod 9 and the positioning post 7. The diameter of the positioning post 7 is equal to the inner diameter of the encapsulation cylinder 6, and the diameter of the connecting rod 9 is smaller than the inner diameter of the encapsulation cylinder 6, so that the positioning post 7 can limit the displacement of the connecting rod 9, thereby preventing the connecting rod 9 from detaching from the encapsulation cylinder 6, ensuring the displacement stability of the movable plate 3, and the elastic deformation of the spring 8 can consume wave energy. Thus, energy dissipation can be achieved through dynamic displacement, achieving the purpose of secondary consumption of wave energy.

[0026] Simultaneously, as the movable plate 3 moves backward, a gap exists between the movable plate 3 and the supporting plate 2, forming a narrow channel. This narrow channel, due to the curvature limitation, generates turbulence and vortices when water flows through it. Furthermore, the water reflects multiple times within the gap, further dissipating energy and achieving a third stage of wave energy dissipation. The water can also flow back through the gap between the movable plate 3 and the supporting plate 2, creating a wave backflow phenomenon. The entire system, through a three-stage energy dissipation mechanism of reflection, elastic energy dissipation, and vortex dissipation, forms an energy attenuation chain, thereby improving the energy dissipation effect on ship waves.

[0027] To prevent direct impact from external forces that could cause twisting and deformation of the connecting rod 9, it is necessary to shield and protect it. An assembly ring 10 is fitted around the front end of the connecting rod 9, and a sealing tube 11 is threadedly connected to the outside of the assembly ring 10. The rear end of the sealing tube 11 is fitted around the front end of the encapsulation cylinder 6. Because the sealing tube 11 is fitted around the front end of the encapsulation cylinder 6, it can shield and protect the connection between the connecting rod 9 and the encapsulation cylinder 6, thus preventing direct impact on the connecting rod 9 and ensuring its performance. Furthermore, the threaded connection between the sealing tube 11 and the assembly ring 10 allows for disassembly of the sealing tube 11, facilitating maintenance of the connecting rod 9. Preferably, a grease injection hole is provided inside the sealing tube 11 for regular maintenance, increasing its service life.

[0028] To ensure the performance of spring 8, it is necessary to replace the worn-out spring 8, such as... Figure 4 and 5 As shown, the rear end of the spring 8 is provided with a sealing post 12 that is threadedly connected to the sealing cylinder 6, and an operating groove 13 is provided on the rear side of the sealing post 12 for easy rotation. The operator can quickly rotate the sealing post 12 by inserting a tool into the operating groove. Rotating the sealing post can adjust the compression of the spring, thereby changing the initial elastic force of the buffer to adapt to wave impacts of different intensities. Since the sealing cylinder 6 is connected to the fixing plate 1 by bolts, after removing the bolts, the sealing cylinder 6 can be easily removed. Then, the sealing post 12 threadedly connected to the sealing cylinder 6 can be rotated to remove the spring 8, which is not limited by the sealing post 12, for replacement, thus achieving the effect of convenient disassembly and assembly of the spring 8.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model are included within the scope of protection of this utility model.
