[0002] When constructing at the seaside or the riverside, a wave resistance device needs to be set up to avoid the influence of large waves on the construction, and a wave resistance device needs to be set up on the seaside flood embankment to dissipate waves and resist floods. The traditional wave resistance device is generally piled up by sandbags, or is a solid stone column fixed on the bank or a net-shaped dam built by cement. The sandbag piling method has poor waterproof effect, and the waterproof performance decreases rapidly after a long time of use. In addition, the sandbag piling method is prone to collapse after being attacked by wind and waves. The solid stone column fixed on the bank or the net-shaped dam built by cement has a large interval between the stone columns, and the distance between the stone columns or the net holes is fixed and cannot be changed. Regardless of the size of the wind and waves, the wave resistance effect is fixed, and different wave resistance effects cannot be produced for different intensities of water waves, which is not conducive to the protective construction of the river embankment. In addition, the wave resistance device fixed on both sides of the riverbed cannot block and eliminate the waves in the water or the water bottom. When water plants that can purify water quality are planted on the water bottom of the river basin to be treated, the large water flow on the water bottom will cause damage to the water plants. SUMMARY

[0010] a main shaft, which extends transversely and has both ends movably penetrating out of the box body; and

[0011] an impeller, which is arranged on the main shaft and is driven by wind to drive the main shaft to rotate;

[0012] the box body is isolated from wind flow in other directions outside, so that the impeller is only driven by the wind flow at the air outlet end of the air inlet pipe;

[0013] The box body extends out a frame in the longitudinal direction;

[0014] The wave resistance mechanism comprises a baffle, the upper end of the baffle is hinged to the extended end of the frame;

[0018] The air inlet pipe comprises:

[0019] A first pipe section extends in the vertical direction, and the upper end of the first pipe section extends out an air inlet pipe opening in the longitudinal direction; and

[0020] A second pipe section extends from the lower end of the first pipe section to the box body;

[0021] The second pipe section comprises an air inlet section, a throat section and a diffusion section arranged sequentially from the lower end of the first pipe section to the box body, and the air inlet section and the diffusion section are tapered towards the throat section.

[0022] Optionally, the baffle comprises:

[0023] A baffle frame, the upper end of the baffle frame is hinged to the frame, and the lower end of the baffle frame is hinged to the two connecting rods; and

[0024] A plurality of baffle pieces extend transversely and are arranged vertically on the baffle frame.

[0025] Optionally, the included angle between the plurality of baffle pieces and the plane on which the baffle frame is located is angularly adjustable.

[0043] In the construction at the seaside or riverside, it is necessary to set up a wave blocking device to avoid the influence of large water waves on the construction, and the wave blocking device needs to be set up on the seaside flood embankment to dissipate waves and resist floods. The traditional wave blocking device is generally piled up by sandbags, and the solid stone columns or cement built net dams fixed on the shore are used to block waves. The sandbag piling method has poor waterproof effect, and the waterproof performance decreases sharply after a long time of use, and it is easy to collapse after being attacked by wind and waves. The solid stone columns or cement built net dams fixed on the shore have large intervals between the stone columns, and the distance between the stone columns or the net holes is fixed and cannot be changed. Regardless of the size of the wind and waves, the wave blocking effect is fixed, and different wave blocking effects cannot be produced for different intensity of water waves, which is not conducive to the protective construction of the river embankment. Moreover, the wave blocking device fixed on both sides of the riverbed cannot block and eliminate the waves in the water or the bottom of the water. When the water quality purifying aquatic plants are planted in the river basin, the large water flow in the bottom of the water will cause damage to the aquatic plants.

[0044] In view of this, the present application provides a wave blocking device, Figures 1 to 3 An embodiment of the wave blocking device provided by the present application directly utilizes wind energy to block waves, uses renewable energy, saves energy and protects the environment, increases the utilization rate of wind energy, stably utilizes wind energy, has low cost, and is suitable for different intensity of water waves and different wave blocking positions. The wave blocking device will be described in detail below in combination with specific drawings.

[0045] Reference Figures 1 to 2 The wave blocking device 100 comprises a box 1, an air inlet pipe 2, a power mechanism 3 and a wave blocking mechanism 4, one end of the air inlet pipe 2 is used for longitudinal air inlet, the other end extends downward to communicate with the box 1, the power mechanism 3 comprises an impeller assembly 31 arranged on the box 1, the impeller assembly 31 is arranged near the air outlet end of the air inlet pipe 2, and the wave blocking mechanism 4 is drivingly connected with the impeller assembly 31 to be driven by the impeller assembly 31 to reciprocate longitudinally.

[0046] In the technical scheme of the present application, one end of the air inlet pipe 2 is used for longitudinal air inlet, and the other end extends to communicate with the box 1. After the air flow flows into the box 1 from the air inlet pipe 2, the impeller assembly 31 is driven to move, and the impeller assembly 31 is driven to move to drive the wave blocking mechanism 4 to reciprocate longitudinally. The wave blocking mechanism 4 reciprocates in the air inlet direction to offset the kinetic energy of the spray. The spray gradually weakens under the blocking action of the wave blocking mechanism 4. The greater the wind wave, the better the effect of converting kinetic energy by the power mechanism 3 to drive the wave blocking mechanism 4 to block the wave. The wave blocking device 100 has simple structure and is convenient to move. It can be arranged at different positions to meet the wave blocking demand. The wave blocking device 100 directly utilizes wind energy to drive the wave blocking mechanism 4 to move to block the wave. It uses renewable energy, saves energy and protects the environment, increases wind energy utilization rate, and has stable wind power utilization and low cost.

[0047] The wave blocking device 100 can be arranged in multiple numbers to be installed on the dike 5 for flood prevention on the seaside to block the spray and prevent flood. It can also be used for other marine devices to block the wave and avoid the influence of large wind wave on the device.

[0048] The impeller assembly 31 has various forms and is not limited in particular. In the embodiment, the impeller assembly 31 comprises a main shaft 311 and an impeller 312. The main shaft 311 extends transversely and movably penetrates the box 1 at both ends. The impeller 312 is arranged on the main shaft 311 and is driven by wind to rotate the main shaft 311. The main shaft 311 outputs power to the wave blocking mechanism 4. Since the impeller assembly 31 is arranged on the box 1, the box 1 isolates the air flow from other directions outside, so that the impeller 312 is only driven by the air flow at the air outlet end of the air inlet pipe 2 to rotate in one direction, avoiding being driven by air flow from different directions to offset part of the kinetic energy and affecting the working efficiency of the device. The impeller 312 has various structures and quantities and is not limited in particular. In the embodiment, two impellers 312 are arranged along the extension direction of the main shaft 311 to improve the wind energy conversion efficiency. The impeller 312 is fixed on the main shaft 311 by key connection to drive the main shaft 311 to rotate. The connection mode is not limited.

[0049] To enable the impeller assembly 31 to drive the wave-damping mechanism 4 to reciprocate longitudinally under the action of wind energy, thereby achieving wave damming, please refer to [link to relevant documentation]. Figure 1 The housing 1 extends longitudinally to form a frame 11. The wave-damping mechanism 4 includes a baffle 41, the upper end of which is hinged to the extended end of the frame 11. The power mechanism 3 also includes two cranks 32 and two connecting rods 33. The two cranks 32 are laterally spaced and one end is connected to the main shaft 311, which extends through both ends of the housing 1. The two connecting rods 33 are laterally spaced and one end is respectively hinged to the other end of the two cranks 32. The other end of the two connecting rods 33 is respectively hinged to the lower end of the baffle 41. The frame 11, the two cranks 32, the two connecting rods 33, and the baffle 41 together form a four-bar linkage. The main shaft 311 rotates under the drive of the impeller 312 to drive the two cranks 32 at both ends to make circular motion around the main shaft 311. The two cranks 32 drive the baffle 41 through the two connecting rods 33. The baffle 41 is hinged to the lower end of the two connecting rods 33 and swings back and forth around the upper end of the frame 11. The waves gradually weaken under the blocking effect of the back and forth swing of the baffle 41.

[0050] The connection method between the two cranks 32 and the main shaft 311 is not limited. In this embodiment, the two cranks 32 are respectively connected to the two ends of the main shaft 311 via splines.

[0051] The baffle 41 achieves wave blocking during its longitudinal reciprocating motion. The specific configuration of the baffle 41 is not limited. In one embodiment, the baffle 41 is a complete plate-like structure. Waves are blocked and offset by the reciprocating motion of the baffle 41. With this configuration, the baffle 41 experiences a large impact force from the water waves, making it prone to damage. The impact force transmitted to the frame 11, the two connecting rods 33, and the two cranks 32 is also significant, making the four-bar linkage structure susceptible to damage and causing device failure, resulting in troublesome maintenance and replacement. In this embodiment, the baffle 41 includes a baffle body 411 with multiple longitudinally penetrating through holes 412 for dispersing water waves and reducing the impact force of the water waves on the baffle body 411. To improve the structural strength of the baffle body 411, please refer to [link to relevant documentation]. Figure 1 The baffle body 411 is curved from top to bottom, which improves the bending stiffness of the baffle body 411, makes the structural strength more reliable, the force transmission path better, and extends the service life of the wave-blocking device.

[0052] In another embodiment, the baffle 41 includes a baffle frame and a plurality of baffle plates. The upper end of the baffle frame is hinged to the frame 11, and the lower end is hinged to the two connecting rods 33. The plurality of baffle plates extend laterally and are arranged vertically on the baffle frame. The plurality of baffle plates are spaced apart to divert water waves. The plurality of baffle plates disperse some of the water waves, while diverting the water waves, reducing the water waves and protecting the baffle 41 from damage.

[0053] To enhance the wave-damping effect, the angle between the plurality of baffle plates and the plane containing the baffle frame can be adjusted. The setting is not limited; specifically, in this embodiment, the upper ends of the plurality of baffle plates are hinged to the baffle frame, and the lower ends can rotate around the hinged ends. During the circular motion of the impeller assembly 31 driving the two cranks 32 around the main shaft 311, when the baffle 41 is driven by the two connecting rods 33 to swing towards the water wave, the multiple baffle plates experience significant water flow resistance. Under the action of water flow resistance, the lower ends of the multiple baffle plates are pushed by the water flow to rotate around the upper ends, and the angle between the multiple baffle plates and the plane where the baffle frame is located increases, offsetting part of the kinetic energy of the water wave. When the baffle 41 is driven away from the water wave by the two connecting rods 33, the multiple baffle plates close due to water resistance. During the reciprocating swing of the baffle 41, the angle between the multiple baffle plates and the plane where the baffle frame is located opens and closes repeatedly, with the same frequency as the water wave, thereby increasing the lifespan of the wave-blocking device 100 and achieving wave blocking while improving the wave-blocking effect. Furthermore, the specific range of the included angle is not limited. In this embodiment, the included angle is not less than 0° and not greater than 60°. The included angle can be limited by setting a limiting structure at the hinge end of the multiple baffle plates and the baffle frame. The limiting structure is not limited in specific terms and can refer to conventional technical means. By limiting the included angle, the opening and closing degree of the multiple baffle plates is controlled, avoiding the situation where the included angle is too large, resulting in a small effective force-bearing area of ​​the multiple baffle plates in contact with the water waves and poor wave-blocking effect. It also avoids the multiple baffle plates rotating upwards beyond the hinge end under the action of water flow, which would prevent them from rotating back to their original position during the reciprocating swing, causing the reciprocating opening and closing to fail and the wave-blocking effect to be weak.

[0054] To ensure the wave-damping device 100 functions properly underwater, it conforms to the angle of the coastline. Specifically, the frame 11 includes two longitudinal beams 111 extending laterally from both ends of the housing 1 and a transverse beam 112 spaced laterally between the two longitudinal beams 111. The extended ends of the two longitudinal beams 111 are hinged to the upper end of the baffle 41. The transverse beam 112 enhances the structural strength of the frame 11, preventing damage under stress. Both the lateral and longitudinal directions are set parallel to the ground. It should be noted that there can be a certain angular deviation between the lateral and longitudinal directions and the ground, while still maintaining the technical effect of the present invention. The effect is better when parallel to the ground.

[0055] There are various types of air inlet pipes 2 used for intake air into the housing 1, and their specific configuration is not limited. In this embodiment, the air inlet pipe 2 includes a first pipe section 21 and a second pipe section 22. The first pipe section 21 extends vertically, and an air inlet 211 extends longitudinally from the upper end of the first pipe section 21. The specific configuration of the air inlet 211 is not limited. In order to improve the wind energy collection effect, the air inlet 211 is gradually widened. The second pipe section 22 extends from the lower end of the first pipe section 21 to the housing 1. Since the wind energy collection is intermittent and difficult to concentrate when relying on natural wind energy, it affects the driving effect of the impeller assembly 31 in converting kinetic energy into the wave-damping mechanism 4. In order to improve the wave-damping effect and increase the wind energy utilization rate, the second pipe section 22 includes an air inlet section 221, a throat section 222, and a diffuser section 223 that are sequentially connected from the lower end of the first pipe section 21 to the housing 1. The air inlet section 221 and the diffuser section 223 are both gradually narrowed towards the throat section 222. The second pipe section 22 is generally shaped like a Venturi tube. Airflow enters from the first pipe section 21 and enters the air inlet section 221 of the second pipe section 22. The cross-sectional area of ​​the air inlet section 221 gradually decreases, and the gas velocity gradually increases. The entire flow undergoes a narrowing process simultaneously, and the pressure also decreases at the same time. At the throat section 222, which is the narrowest point of the second pipe section 22, the dynamic pressure reaches its maximum value, and the static pressure reaches its minimum value. This pressure difference accelerates the gas velocity, increases the rotational speed of the impeller assembly 31, drives the wave-damping mechanism 4, and increases the utilization rate of wind energy.

[0056] In order to control the wave-blocking operation of the wave-blocking device 100 according to the wind force on the water surface, the wave-blocking device 100 also includes an airflow sensor, a pneumatic valve, and a control device. The airflow sensor is located at the air inlet end of the air inlet pipe 2 and is used to detect the wind force on the water surface. The pneumatic valve is located at the air outlet end of the air inlet pipe 2. The control device is electrically connected to the airflow sensor and the pneumatic valve and is used to control the opening and closing of the pneumatic valve according to the sensing signal of the airflow sensor, thereby controlling the wave-blocking mechanism 4.
