Obviously, the described embodiments are only some of the embodiments of the application, not all the embodiments. The application will be described below in one of the embodiments in combination with the specific embodiments. The drawings are only used for illustrative description, and the representation is only a schematic diagram, not a physical diagram, and cannot be understood as a limitation on the patent; in order to better illustrate the embodiments of the application, some components in the drawings are omitted, enlarged or reduced, and do not represent the size of the actual product; it is understandable for those skilled in the art that some known structures and their descriptions in the drawings can be omitted.

[0026] As Figures 1-2As shown, the embodiment provides a connected wave energy generating device, which comprises an underwater floating body 7, a floater component, a plurality of anchor blocks 1, anchor chains 2 and a power generating component. The underwater floating body 7 is provided with a through hole, and the floater component is slidingly installed in the through hole. Each anchor block 1 is fixed in the sea in an interval manner. Each anchor block 1 is provided with an anchor chain 2 between the underwater floating body 7. The power generating component comprises a power generating coil 6 and a magnet 8. The power generating coil 6 is wound on the inner wall of the floater component. The magnet 8 is arranged on the inner wall of the through hole. A sealing device 9 is arranged between the floater component and the underwater floating body 7 for preventing water from entering the power generating component. When the floater component oscillates up and down along the axis of the through hole with the sea wave, the power generating coil 6 is driven to cut the magnetic lines generated by the magnet 8 in the through hole.

[0027] The floater component comprises a main floater 3, a plurality of balance floaters 5 and connecting rods 4. The main floater 3 is slidingly arranged in the through hole. The plurality of balance floaters 5 are arranged around the main floater 3 in an interval manner. The connecting rod 4 is arranged between each main floater 3 and balance floater 5.

[0028] Specifically, in the embodiment, the device comprises at least three anchor blocks 1 and anchor chains 2 fixed on the anchor blocks 1. The device further comprises a main floater 3. The main floater 3 is sequentially provided with a disc part, a prism part and a pyramid part. The prism part is preferably a quadrangular prism. The pyramid part is preferably a quadrangular pyramid. The disc part of the main floater 3 floats on the water surface. The middle prism part and the lower pyramid part are both underwater. Four connecting rods 4 are uniformly fixed and connected to the outer wall of the upper part of the main floater 3. The connecting rods 4 are preferably rigid structures. Balance floaters 5 are fixed and connected to the other ends of the connecting rods 4. The middle part of the main floater 3 is provided with power generating coils 6. The main floater 3 is sleeved with an underwater floating body 7. Magnets 8 are fixed and connected to the inner wall of the underwater floating body 7. The magnets 8 are sleeved with the coils. One end of the anchor chain 2 is fixed on the bottom of the sea water. The other end of the anchor chain 2 is uniformly fixed and connected to the outer wall of the underwater floating body 7. The bottom and the top of the underwater floating body 7 are symmetrically fixed and connected with sealing devices 9. The sealing devices 9 are preferably sealing rings. The other end of the sealing device 9 on the upper side of the underwater floating body 7 is fixed and connected with the disc part of the main floater 3. The other end of the sealing device 9 on the lower side of the underwater floating body 7 is fixed and connected with the pyramid part of the main floater 3.

[0029] When the present embodiment is in use, the main float 3 floats on the water surface and performs a heaving motion along the axis of the through hole under the action of waves. If the main float 3 performs a motion other than heaving, when the buoyancy of the main float 3 changes, since the main float 3 and the balancing float 5 are connected by a rigid connecting rod 4, the equilibrium state of the balancing float 5 is also destroyed, and the buoyancy changes, but the gravity of the two does not change. A restoring torque is formed between the buoyancy and the gravity, which can prevent the movement of the main float 3 and the balancing float 5. Therefore, except for the heaving direction movement, the other degrees of freedom of the main float 3 are suppressed, that is, the main float 3 can only perform a single degree of freedom heaving motion that can capture wave energy. Movement, and the captured wave energy will not be converted into invalid motion of other degrees of freedom, which is used to improve the utilization rate of wave energy. In addition, the anchor chains 2 are evenly distributed on the underwater buoy 7, and the anchor blocks 1 are buried in the seabed ground to further restrict the movement of each degree of freedom of the underwater buoy 7 through the anchor chains 2. When the main buoy 3 performs reciprocating up and down heave and sink motion under the action of waves, the power generation coil 6 on the main buoy 3 cuts the magnetic lines of force of the magnet 8 to generate electrical energy, and the generated electrical energy can be collected by the power generation system in the prior art for use by the load, and the gap between the underwater buoy 7 and the main buoy 3 is sealed by a sealing ring to prevent the power generation coil 6 and the magnet 8 from contacting water and failing.

[0030] Furthermore, if Figure 1 、 3 As shown, the anchor block 1 is provided with a drainage end 15 and a ground plug end 10. A reel 11, a first pull rope, and an adjustment float 17 are provided inside the drainage end 15. The two ends of the reel 11 respectively pass through the two opposite side walls of the drainage end 15. The first pull rope is wound around the reel 11. The adjustment float 17 is connected to the free end of the first pull rope. The wall surface of the drainage end 15 is provided with a flow groove 16 for the circulation of seawater.

[0031] The ground plug end 10 is fixed in the ocean, and a second pull rope, a sealing plate 13 and a tension spring 14 are provided inside the ground plug end 10. A connecting water hole 12 is provided on the side wall of the ground plug end 10 and the drainage end 15. The second pull rope is wrapped around the end of the winding rod 11 extending into the ground plug end 10. The sealing plate 13 is connected to the free end of the second pull rope. One end of the tension spring 14 is fixed to the side wall of the ground plug end 10, and the other end of the tension spring 14 is connected to the sealing plate 13. The sealing plate 13 can realize the opening and closing of the water hole 12.

[0032] It should be noted that, since the water level varies during the ebb and flow of the ocean, in order to prevent the water level from being too high, causing the seawater to completely submerge the main float 3 and the balance float 5, resulting in failure of wave energy conversion, or the water level from being too low, causing the anchor chain 2 to fail to pull the underwater float 7, resulting in failure of the anchoring effect of the underwater float 7, and resulting in failure of wave energy conversion, in this embodiment, the ground plug end 10 and the drainage end 15 are preferably designed as retractable structures respectively;

[0033] Specifically, the ground insertion end 10 and the drainage end 15 are preferably vertically arranged, the drainage end 15 is preferably arranged as a right-angle pipe, a flow-through groove 16 capable of allowing seawater to flow through is formed on the outer wall of the drainage end 15, and the winding rod 11 is rotatably arranged in the drainage end 15. A first pull rope is wound around the rod segment of the winding rod 11 inside the drainage end 15, the free end of the first pull rope is connected to the bottom of the adjusting float 17, one end of the winding rod 11 extends to the upper side of the ground insertion end 10, the other end of the winding rod 11 penetrates through the inner wall of the drainage end 15 to the outside thereof, the inner wall of the ground insertion end 10 is provided with a water hole 12 communicating with the drainage end 15, a sealing plate 13 is sealingly and slidably connected to the inner wall of the ground insertion end 10, the sealing plate 13 can cover or open the water hole 12, a second pull rope is wound around one end of the winding rod 11 inside the ground insertion end 10, the free end of the second pull rope is connected to the top of the sealing plate 13, and the bottom of the sealing plate 13 is fixedly connected with a tension spring 14, the other end of the tension spring 14 is fixedly connected with the inner wall of the ground insertion end 10.

[0034] In use, the ground insertion end 10 is directly inserted into the underwater ground, so that the anchor block 1 can be conveniently fixed, the outer wall of the ground insertion end 10 is fixedly connected with the drainage end 15, seawater can enter the inside of the drainage end 15 through the flow-through groove 16, so that the seawater level in the drainage end 15 is consistent with the seawater level outside, when the tide rises, the seawater level rises, the seawater level in the drainage end 15 also rises at the same time, so that the adjusting float 17 arranged inside the drainage end 15 also rises with the rising of the seawater level, when the adjusting float 17 rises, the first pull rope is pulled to pull the winding rod 11, so that the winding rod 11 rotates and pulls the sealing plate 13 through the second pull rope, so that the sealing plate 13 moves upward and no longer covers the water hole 12, at this time, seawater enters the inside of the ground insertion end 10 through the flow-through groove 16 and the water hole 12 in turn, so that the seawater enters the inside of the ground insertion end 10, with the increase of the amount of seawater, the length of the ground insertion end 10 gradually elongates, thereby improving the pulling force on the underwater floating body 7 through the anchor chain 2, after the rising position of the adjusting float 17 is stable, the adjusting float 17 no longer pulls the winding rod 11, so that the pulling force of the tension spring 14 on the sealing plate 13 is greater than the pulling force of the second pull rope on the sealing plate 13, the sealing plate 13 is moved back by the tension spring 14, so as to reseal the water hole 12, and the inside of the ground insertion end 10 is already filled with seawater, the compressibility of seawater is small, at this time, the ground insertion end 10 cannot compress seawater to shorten again, but if the seawater level continues to rise, the ground insertion end 10 can be pulled to elongate again, so that the anchor block 1 can rise with the rising of the water level, so that the main float 3 and the balance float 5 can rise with the rising of the water level, so that the effect of the main float 3 generating electricity by using wave energy will not be invalid due to the rising of the water level.

[0035] Similarly, when the tide recedes, the sea level drops, the regulating float 17 drops and no longer pulls the winding rod 11, at this time the tension spring 14 will pull the sealing plate 13 downward under its own elastic force, so that the sealing plate 13 no longer seals the water hole 12, and because the water level drops, the underwater float 7 no longer pulls the anchor block 1, at this time the ground insertion end 10 will shorten under its own gravity, expelling the seawater in the ground insertion end 10, until the regulating float 17 pulls the winding rod 11 again, so that the winding rod 11 pulls the sealing plate 13 to reseal the water hole 12, so that the ground insertion end 10 can automatically shorten as the water level drops, thereby preventing the water level from being too low, causing the pulling effect of the anchor chain 2 on the underwater float 7 to fail, causing the anchoring effect of the underwater float 7 to fail, and further causing the wave energy conversion to fail.

[0036] Further, as shown in Figure 3 , the drainage end 15 is provided with a rotatable drainage plate, specifically, a drainage plate 18 is arranged on the upper outer wall of the right-angle pipe, and a rotating shaft 19 is fixedly connected to the upper outer wall of the right-angle pipe, the outer wall of the rotating shaft 19 is fixedly connected to the inner wall of the drainage plate 18, so that the drainage plate 18 can rotate freely.

[0037] It should be noted that in use, the regulating float 17 in the drainage end 15 can extend and shorten with the change in water level, so that the top of the right-angle pipe is always flush with the water level, thereby preventing the wave from hitting the right-angle pipe 15, causing the ground insertion end 10 to tilt after being hit, resulting in poor firmness of the ground insertion end 10. In the present embodiment, the top of the drainage end 15 is preferably designed as a sealed end, which can prevent seawater from entering the right-angle pipe and affecting the regulating float 17. When the top of the right-angle pipe is provided with a drainage plate, the impact force of the wave hitting the top of the right-angle pipe can be greatly reduced by using the drainage plate 18 to "break" the wave, thereby further increasing the firmness of the ground insertion end 10. By fixing the rotating shaft 19 on the upper side of the right-angle pipe, and fixing the inner wall of the drainage plate 18 to the outer wall of the rotating shaft 19, the drainage plate 18 can rotate, so that the drainage plate 18 can twist when facing waves of different angles, allowing the drainage plate 18 to drain waves of different angles and reduce the impact force of the wave hitting the top of the right-angle pipe.

[0038] Further, as shown in Figures 4-5 , to prevent the flow-through groove 16 from being blocked, a filter plate is provided at the flow-through groove of the drainage end in the present embodiment, and a scraper 21 is installed at the end of the winding rod 11 extending to the outside, the outer wall of the scraper 21 can be attached to the outer wall of the filter plate 20.

[0039] It should be noted that in use, in order to prevent the shell, screw and small fish into the inside of the right-angle pipe or into the inside of the ground plug end 10, causing the ground plug end 10 to stretch and be stuck or to bite the rope on the winding rod 11, preferably a filter plate 20 is fixedly connected to the inner wall of the flow-through groove 16, for preventing the shell, screw and small fish from entering, and in order to prevent the shell, screw and the like from being attached to the filter plate 20, causing the water passing performance of the filter plate 20 to be reduced, causing seawater to be unable to pass through the filter plate 20 into the inside of the right-angle pipe, thereby causing the stretching effect of the ground plug end 10 to be invalid, therefore a scraper 21 is provided, which will be rotated together with the winding rod 11 when the winding rod 11 is rotated, and the rotation of the scraper 21 will scrape the surface of the filter plate 20, thereby preventing the shell, screw and the like from being adsorbed on the filter plate 20, causing the water inlet effect to be invalid.

[0040] Further, as shown in Figure 2 In order to further improve the sealing effect, the inside of the sealing device 9 in the embodiment is filled with water-swelling rubber, that is, the wall of the sealing ring is preferably hollow and filled with water-swelling rubber 23; in use, in order to prevent the sealing ring from aging and breaking or being bitten and broken by fish, causing the sealing effect to disappear, causing seawater to enter the inside of the sealing ring and contact the power generation coil 6 and the magnet 8, causing power generation to fail, the inside of the sealing ring is hollow and filled with water-swelling rubber 23, when the sealing ring is broken, the water-swelling rubber 23 swells by absorbing water, thereby plugging the hole and preventing seawater from entering the inside of the sealing ring.

[0041] Further, as shown in Figures 1-2 In order to improve the utilization rate of seawater wave energy, in the embodiment, a hydraulic cylinder 22 is arranged between the main float 3 and the underwater float 7, that is, the housing of the hydraulic cylinder 22 is fixed to the top of the underwater float 7, and the driving end of the hydraulic cylinder 22 is connected with the main float 3.

[0042] In use, when the main float 3 moves up and down with the sea waves, the relative movement between the main float 3 and the underwater float 7 drives the hydraulic cylinder 22 to stretch, converting the wave energy into hydraulic energy, thereby increasing a way of energy conversion, and the hydraulic cylinder 22 can vertically fix the main float 3 and the underwater float 7, thereby preventing the power generation coil 6 and the magnet 8 from directly contacting each other, causing them to wear or fail to generate electricity.

[0043] Working principle:

[0044] As Figures 1-3As shown, the main float 3 floats on the water surface and performs heaving motion along the through-hole axis under the action of waves, the anchor chain 2 is uniformly distributed on the underwater floating body 7, and the anchor block 1 is embedded in the water bottom ground to further limit the motion of the underwater floating body 7; when the main float 3 performs reciprocating up-and-down heaving motion under the action of waves, the power generation coil 6 on the main float 3 cuts the magnetic lines of force of the magnet 8 to generate electric energy, which can be collected by the existing power generation system for load use; the gap between the underwater floating body 7 and the main float 3 is sealed by the sealing ring to prevent the power generation coil 6 from being water-contacted and invalid; meanwhile, the cooperation of the ground insertion end 10 and the drainage end 15 enables the anchor block 1 to adjust the stretching force on the underwater floating body 7 according to the sea level, so as to prevent the sea level from being too low to cause the pulling effect of the anchor chain 2 on the underwater floating body 7 to be invalid, the anchoring effect of the underwater floating body 7 to be invalid, and the sea wave energy conversion to be invalid.
