In order to prevent this from happening, slope protection or wave-breaking boards are usually set up on the coastal slopes to resist the impact of seawater. Coastal slope protection usually includes slope type, vertical wall type, open type, floating type, etc.

[0003] Although the existing coastal revetment protects the coast by setting up wave-breaks to prevent the coast from being directly eroded by waves, the wave-breaks in the existing coastal revetment are usually directly impacted by waves, making the wave-break structure vulnerable to damage, thereby shortening the service life of the revetment. At the same time, the utilization efficiency of tidal energy in the existing coastal revetment is low. Summary of the invention

[0045] The present invention is described in detail below in conjunction with embodiments, but the present invention is not limited to these embodiments.

[0046] The embodiment of the present invention provides a coastal slope protection for developing ocean tidal energy, such as Figures 1 to 13 As shown, the coastal slope protection includes:

[0047] A fixed frame 100 is fixed on the coast;

[0048] The limiting mechanism 200 is connected to a side of the fixing frame 100 away from the coast;

[0049] The blocking mechanism 300 is arranged on the limiting mechanism 200; the limiting mechanism 200 is used to limit the horizontal position of the blocking mechanism 300, and the blocking mechanism 300 is used to block the waves;

[0050] The diversion mechanism 400 is connected to the side wall of the limiting mechanism 200 away from the fixing frame 100, and is used to divert the sea waves to the two ends of the limiting mechanism 200;

[0051] At least two power generation mechanisms 500 are respectively arranged at two ends of the limiting mechanism 200, and are used to rotate and generate electricity under the drive of the diverted waves.

[0052] refer to Figures 1 to 4 As shown, the coastal slope protection provided by the embodiment of the present invention includes a fixing frame 100 fixedly arranged on the coast, the fixing frame 100 is fixedly connected to a limiting mechanism 200 on a side away from the coast, a blocking mechanism 300 is slidably connected inside the limiting mechanism 200, and the limiting mechanism 200 is respectively provided with a diverter mechanism 400 and a pair of power generation mechanisms 500 on a side away from the fixing frame 100, the diverter mechanism 400 is fixedly connected to the limiting mechanism 200, and the two power generation mechanisms 500 are located at two ends of the limiting mechanism 200 that are away from each other.

[0053] The outer diameter of the blocking mechanism 300 is smaller than the inner diameter of the limiting mechanism 200, so that the blocking mechanism 300 can slide up and down in the limiting mechanism 200. This reduces the sense of obstruction when the blocking mechanism 300 slides up and down in the limiting mechanism 200.

[0054] The blocking mechanism 300 is used to block the impact of waves, the limiting mechanism 200 is used to limit the horizontal position of the blocking mechanism 300, and the diversion mechanism 400 is used to divert the waves.

[0055] Furthermore, the limiting mechanism 200 includes:

[0056] The limiting seat 210 is connected to a side of the fixing frame 100 away from the coast;

[0057] The limiting cavity 220 is vertically penetrated and opened on the limiting seat 210 . The blocking mechanism 300 is disposed in the limiting cavity 220 and can slide up and down in the limiting cavity 220 . The limiting cavity 220 is used to limit the horizontal position of the blocking mechanism 300 .

[0058] In the embodiment of the present invention, installation notches 230 are provided at both ends of the limiting seat 210; the power generation mechanism 500 passes through the installation notches 230 and is connected to the blocking mechanism 300; the blocking mechanism 300 is used to drive the power generation mechanism to rotate and generate electricity during the up and down sliding process.

[0059] The blocking mechanism 300 can follow the rise and fall of the sea level, and in the process of the blocking mechanism 300 moving up and down, the blocking mechanism 300 can drive the power generation mechanism 500 to rotate and generate electricity;

[0060] The sea waves diverted by the diversion mechanism 400 flow to the two power generation mechanisms 500 respectively, and are used to drive the two power generation mechanisms 500 to rotate and generate electricity.

[0061] In actual application, when the waves flow from the sea surface to the shore, the blocking mechanism 300 blocks the waves from hitting the coast. During this process, the limiting mechanism 200 always limits the horizontal position of the blocking mechanism 300. Before the waves contact the blocking mechanism 300, the diversion mechanism 400 will first divert the waves to reduce the impact force caused by the waves on the blocking mechanism 300.

[0062] In order to ensure the stability of the blocking mechanism 300 during operation, the present application provides a limiting mechanism 200 capable of limiting the horizontal position of the blocking mechanism 300 (mainly referring to the offshore distance of the blocking mechanism 300 ).

[0063] like Figure 5 As shown, the limiting mechanism 200 includes a limiting seat 210 fixedly connected to the fixing frame 100 , a limiting cavity 220 is vertically penetrated inside the limiting seat 210 , and installation notches 230 are formed at both ends of the limiting seat 210 that are away from each other.

[0064] It should be noted that in the marine environment, the impact force of the waves is multi-directional. In addition to the vertical slapping, there is also a strong horizontal thrust. When the waves impact the blocking mechanism 300 at a certain angle, a huge horizontal component force will be generated. The limit seat 210 can prevent the blocking mechanism 300 from excessive lateral displacement under the action of this horizontal force by limiting the horizontal position of the blocking mechanism 300. For example, during a storm surge, the energy of the waves is huge, and the horizontal impact force may cause the blocking mechanism 300 to be knocked down like a domino. The limit seat 210 is like a sturdy "shackle", which fixes the blocking mechanism 300 within a certain horizontal range, so that it can stably resist the lateral impact of the waves, thereby enhancing the stability of the entire coastal protection structure.

[0065] In addition, the limit seat 210 puts the blocking mechanism 300 in a more favorable force-bearing position when it is impacted by waves. When the horizontal position of the blocking mechanism 300 is limited, it can better absorb and disperse the energy of the waves in the vertical direction. Because the movement of the blocking mechanism 300 is constrained within a reasonable range, its vibration and deformation in the vertical direction can be more regular, thereby more effectively converting the impact force of the waves into its own elastic potential energy and other forms for absorption and dispersion. For example, without the limit seat 210, the blocking mechanism 300 may produce disordered movement in both the horizontal and vertical directions, resulting in uneven energy absorption and dispersion. With the limit seat 210, this situation can be improved, so that the blocking mechanism 300 can cope with the impact of waves more efficiently.

[0066] In order to adapt to the changes in sea level during the ebb and flow of the tide, the blocking mechanism 300 used in the present application is able to float up and down with the sea level.

[0067] Specifically, the blocking mechanism 300 includes:

[0068] The baffle plate 310 is disposed in the limiting cavity 220; the top of the baffle plate 310 extends out of the limiting cavity 220;

[0069] The floating plate 320 is connected to the bottom of the baffle 310; the width of the floating plate 320 is greater than the width of the limiting cavity 220;

[0070] The two racks 330 are respectively fixed on the two end walls of the baffle 310 .

[0071] refer to Figures 6 to 8 As shown, the blocking mechanism 300 includes a baffle 310, which is slidably connected to the limiting cavity 220. A floating plate 320 is fixedly connected to the bottom of the baffle 310, and the width of the floating plate 320 is greater than the width of the limiting cavity 220.

[0072] Furthermore, racks 330 are fixedly connected to both sides of the floating plate 320 away from each other, and the distance between the two ends of the two racks 330 away from each other is less than the length of the limiting cavity 220. The floating plate 320 is made of high-density polyethylene.

[0073] Preferably, the top of the baffle 310 is in an inverted J-shape.

[0074] It should be noted that the tides of the ocean will cause the sea level to rise and fall periodically. If the baffle 310 is fixed, it may be exposed too much above the water surface at low tide, causing some waves to bypass the bottom of the baffle 310; at high tide, seawater may overflow the top of the baffle 310. The baffle 310 that can float up and down can automatically adjust its position according to the changes in the tide, and always maintain a suitable height to block the waves. For example, in sea areas with large tidal ranges, such as the Bay of Fundy in Canada (the maximum tidal range can reach about 16 meters), the floating baffle 310 can be lowered to a suitable position at low tide to block the intrusion of waves from the bottom, and rise at high tide to prevent the seawater from easily crossing the baffle 310, thereby achieving effective protection at all tide levels.

[0075] In addition, the baffle 310 that floats up and down with the sea level can better match the dynamic height of the waves. When the waves hit, the baffle 310 can interact with the waves at a suitable height to more effectively absorb and disperse the energy of the waves. Compared with the fixed baffle 310, the floating baffle 310 can dynamically adjust its position according to the actual height and energy distribution of the waves, so that the angle and strength of the waves impacting the baffle 310 are more uniform, thereby improving the energy absorption efficiency. For example, in the case of irregular waves, the floating baffle 310 can float up and down flexibly, so that the impact force of the waves is more evenly distributed on the surface of the baffle 310, reducing damage caused by excessive local impact force.

[0076] That is, the bottom of the floating plate 320 is in direct contact with the sea level, and the buoyancy generated by the floating plate 320 lifts the baffle 310, so that the baffle 310 can slide up and down in the limiting seat 210 following the change of the sea level.

[0077] The floating plate 320 is made of high-density polyethylene and has the following advantages:

[0078] (1) Regarding buoyancy: High-density polyethylene (HDPE) is a lightweight material with a density of approximately 0.94 g / cm³ to 0.965 g / cm³, which enables it to generate sufficient buoyancy in water. Since its density is less than that of water (the density of water is approximately 1 g / cm³), according to the buoyancy principle (buoyancy is equal to the weight of the liquid displaced), the floating plate 320 made of HDPE material can easily float on the water surface. For example, a HDPE floating plate 320 with a volume of 1 m³ is subjected to a buoyancy of approximately 1000 kg in water (ignoring the weight of the floating plate 320 itself), and can carry objects of considerable weight.

[0079] (2) Regarding mechanical strength: HDPE has good mechanical properties. Its tensile strength is relatively high, generally around 20MPa~30MPa, which means that it is not easy to break when subjected to tension. In the marine environment, the floating plate 320 may be subjected to the impact of waves, the pulling of water flow and other forces. The high tensile strength of HDPE can ensure that the floating plate 320 remains intact under these external forces. At the same time, it also has good impact resistance and can withstand a certain degree of collision without damage. For example, when the floating plate 320 is hit by floating objects or collides with other equipment, the HDPE material can effectively disperse the impact force and reduce the possibility of damage.

[0080] The top of the baffle 310 is set to be an inverted J shape, which has the following advantages:

[0081] (1) Reducing local pressure peaks: The inverted "J"-shaped structure distributes the impact force of the waves over a larger area, thereby reducing the local pressure peaks. In fluid mechanics, when a fluid impacts the surface of an object, the pressure distribution is closely related to the shape of the object. This special top shape can make the pressure generated by the impact of the waves more evenly distributed on the "J"-shaped surface, reducing the possibility of local excessive pressure. This is very important for extending the service life of the baffle 310 and maintaining its structural integrity.

[0082] (2) Increased effective height: The inverted "J"-shaped top structure has an extended portion in the vertical direction, which is equivalent to increasing the effective height of the baffle 310. At high tide or when the waves are large, the seawater needs to overcome a higher obstacle to pass over the baffle 310. For example, when the tide level and wave height are both high, an ordinary baffle may be easily passed over by the waves, while the baffle 310 with an inverted "J"-shaped top can better block the waves and prevent the seawater from passing over the baffle 310 and causing damage to the rear area.

[0083] (3) When the waves approach the top of the baffle 310, the “J”-shaped structure guides the seawater to flow along its curved portion. This guiding effect makes it difficult for the seawater to directly pass over the baffle 310, but tends to flow downward along the outer side of the “J” shape. This is like setting a “circuitous route” for the seawater, increasing the difficulty for the seawater to pass over the baffle 310.

[0084] In order to reduce the energy contained in the waves from being directly transferred to the baffle 310, the present invention provides a diversion mechanism 400 that can reduce the energy of the waves.

[0085] Specifically, refer to Fig. 9 and Fig.10 , the diverter mechanism 400 is a diverter plate; the thickness of the diverter plate gradually decreases from the middle of the side wall of the limiting mechanism to the two ends.

[0086] The functions of the manifold with the above structural design are as follows:

[0087] (1) The water flow guidance and dispersion function is enhanced.

[0088] Efficiently guide water flow: When the waves hit the baffle 310, the diverter is located on the side close to the sea surface, and its main function is to guide the water flow. Since the thickness gradually decreases from the middle to the two ends, when the water flow contacts the diverter, the thicker part in the middle first has a greater blocking and guiding effect on the water flow. Just like reefs in a river, the protruding part in the middle first changes the direction of the water flow. For example, under the impact of large waves, the water flow will be diverted to the two ends along the thicker part in the middle. This design allows the water flow to be guided more directionally, thereby effectively avoiding the water flow from concentrating on a certain position of the baffle 310.

[0089] Evenly disperse the energy of water flow: The gradient thickness design enables the diverter plate to disperse the energy of water flow more evenly. When the water flows through the diverter plate, the thickness gradually decreases from the middle to the two ends, which can gradually reduce the pressure of the water flow and avoid the concentration of pressure in a certain local area. From the energy perspective, the kinetic energy of the water flow is more evenly distributed on the diverter plate, reducing the risk of damage to the diverter plate or baffle 310 due to excessive local energy. For example, if the diverter plate is of equal thickness, the water flow may generate greater pressure and energy concentration in the middle part when it impacts, but the gradient thickness design can effectively avoid this situation.

[0090] (2) Reduce resistance and vibration.

[0091] Reduce hydrodynamic resistance: In seawater, the shape and structure of objects have a great influence on hydrodynamic resistance. The gradient thickness design of the splitter can reduce its resistance in the water. The thinner ends are relatively less resistant in the water flow, while the middle part mainly plays a guiding and diverting role, so the appropriate thickness will not cause excessive resistance. This design conforms to the principles of fluid mechanics, making the splitter move more smoothly in the water flow and reducing the energy loss caused by resistance. For example, compared with a splitter of equal thickness and thicker, this gradient thickness design may reduce the resistance in the water flow by 30%~50% (the specific value depends on factors such as water flow speed and splitter size).

[0092] Reduce vibration: When water flows impact the diverter plate, the diverter plate of equal thickness may vibrate due to the uneven impact of the water flow. The diverter plate of gradient thickness can effectively reduce vibration because it can disperse the energy of the water flow more evenly and reduce the resistance. In the marine environment, vibration may cause structural fatigue and damage. By reducing vibration, the service life of the diverter plate and the baffle 310 can be extended. For example, under long-term wave impact, the vibration amplitude generated by the diverter plate of gradient thickness may be only about half of that of the diverter plate of equal thickness, which is very important for maintaining the stability of the structure.

[0093] (3) Improve structural stability and durability.

[0094] More reasonable stress distribution: The design of gradually decreasing thickness from the middle to the two ends makes the stress distribution of the manifold more reasonable when it is subjected to water flow pressure. The middle part is thicker and can withstand greater pressure, while the thinner parts at the two ends withstand relatively less pressure. This gradual stress distribution conforms to the actual situation of water flow impact. For example, in the simulated water flow impact test, the stress concentration phenomenon of the manifold with gradually variable thickness is significantly reduced when it is subjected to greater water flow pressure, and the stability of the structure is improved.

[0095] Improved corrosion resistance: In marine environments, the durability of structures is closely related to corrosion. Since the diverter plate with gradient thickness can guide water flow and disperse energy more effectively, the retention time and turbulence of water flow on the diverter plate surface are reduced. This reduces the chemical corrosion and abrasion between seawater and the diverter plate surface, thereby improving the corrosion resistance of the diverter plate. For example, in a salt spray environment test, the surface corrosion rate of a diverter plate with gradient thickness may be 20%~30% lower than that of a diverter plate with equal thickness.

[0096] It should be noted that the sea waves originally flowing toward the baffle 310 will be redirected after being diverted by the diverter plate, and the redirected sea waves will flow toward the turbine 510, thereby driving the turbine 510 to rotate and generate electricity.

[0097] In order to generate electricity using ocean tidal energy, the present application provides a power generation mechanism 500 that absorbs ocean wave energy.

[0098] Specifically, the power generation mechanism 500 includes:

[0099] The water turbine 510 is fixed on the limiting seat 210;

[0100] The gear 520 is disposed at the mounting notch 230 and is coaxially connected to the output shaft of the turbine 510 for meshing with the rack 330 .

[0101] refer to Figures 11 to 13 As shown, the power generation mechanism 500 includes a turbine 510 and a gear 520 . The turbine 510 is fixedly connected to the limit seat 210 . The gear 520 is meshed with the rack 330 at the corresponding position. The gear 520 is coaxially connected to the input shaft of the turbine 510 .

[0102] It should be noted that, in the process of the baffle 310 moving up and down with the sea level, the racks 330 on both sides of the baffle 310 move up and down synchronously with the baffle 310, and the racks 330 drive the gear 520 meshing with one side to rotate, and the gear 520 is coaxially connected to the output shaft of the turbine 510, so the baffle 310 moving up and down drives the turbine 510 to rotate. The turbine 510 is usually connected to a hydroelectric generator, thereby using the ocean tidal energy to generate electricity.

[0103] In summary, the working principle of the present invention is as follows:

[0104] When the waves hit the baffle 310 at a certain angle, a huge horizontal force component is generated. The limit seat 210 can prevent the baffle 310 from excessive lateral displacement under the action of such horizontal force by limiting the horizontal position of the baffle 310, and fix the baffle 310 within a certain horizontal range, so that it can stably resist the lateral impact of the waves, thereby enhancing the stability of the entire coastal protection structure.

[0105] The bottom of the floating plate 320 is in direct contact with the sea level, and the buoyancy generated by the floating plate 320 lifts the baffle 310, so that the baffle 310 can slide up and down in the limiting seat 210 following the change of the sea level.

[0106] The top of the baffle 310 is designed as an inverted J-shaped structure with an extension in the vertical direction, which is equivalent to increasing the effective height of the baffle 310. At high tide or when the waves are large, the seawater needs to overcome a higher obstacle to pass over the baffle 310. When the waves approach the top of the baffle 310, the "J"-shaped structure guides the seawater to flow along its curved part. This guiding effect makes it difficult for the seawater to directly pass over the baffle 310, but tends to flow downward along the outer side of the "J" shape.

[0107] Since the distance between the distal ends of the two racks 330 is smaller than the length of the limiting cavity 220 , the sense of obstruction when the baffle 310 slides up and down in the limiting cavity 220 is reduced.

[0108] The sea waves originally flowing toward the baffle 310 will be redirected after being diverted by the diverter plate, and the redirected sea waves will flow toward the turbine 510, thereby driving the turbine 510 to rotate and generate electricity.

[0109] The coastal slope protection for developing ocean tidal energy provided by the present invention divides the sea waves into two streams through the diversion mechanism 400, and drives the power generation mechanisms 500 on both sides to rotate and generate electricity, thereby significantly improving the energy capture efficiency. At the same time, the setting of the diversion mechanism 400 can reduce the direct impact of the sea waves on the blocking mechanism 300, thereby extending the service life of the structure.

[0110] The above are only a few embodiments of the present application and do not constitute any form of limitation to the present application. Although the present application is disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with the profession, without departing from the scope of the technical solution of the present application, using the technical content disclosed above to make slight changes or modifications are equivalent to equivalent implementation cases and fall within the scope of the technical solution.
