The present invention converts wave flow motion into power to directly drive the generator 12 through the magnetic suspension piston 1, which reduces the transmission steps and reduces energy loss compared with the existing wave flow energy generation equipment.

[0031] The generator 12 is arranged on a generator fixing frame 14, the generator fixing frame 14 is arranged on a deck 6, and the deck 6 is arranged on the magnetic suspension piston 1. The generator fixing frame 14 is arranged to provide a fixing means for the generator 12 to ensure the normal operation of the generator; the deck 6 is arranged to provide a working environment for the generator 12.

[0032] The generator 12 is connected to the rotating gear 13 through a transmission shaft, and the rotating gear 13 is meshed with the horizontal moving gear 11. The outer sides of the rotating gear 13 and the horizontal moving gear 11 are provided with a gear sliding cabin 9; the bottom surface of the horizontal moving gear 11 is connected to the horizontal moving gear connecting shaft 108, and the horizontal moving gear connecting shaft 108 passes through the deck gear connecting shaft slide groove 10 and is connected to the moving magnet fixing plate 107. By providing the horizontal moving gear connecting shaft 108, the reciprocating motion benefit of the magnetic suspension piston is transmitted to the horizontal moving gear 11 through the horizontal moving gear connecting shaft 108, and the horizontal moving gear 11 is meshed with the rotating gear 13, and the rotating gear 13 rotates through the transmission shaft to drive the generator 12 to start generating electricity.

[0033] At least two parallel magnetic suspension piston connection beams 16 are arranged on the gravity foundation 15 , and a plurality of lifting ears 17 are symmetrically arranged on the magnetic suspension piston connection beams 16 .

[0034] A generator room 7 is arranged on the outside of the generator 12 to protect the generator 12, and a generator room hatch cover 8 is arranged on the top surface of the generator room 7, through which the generator room hatch cover 8 is convenient for maintenance work on the generator 12; a gear sliding cabin 9 is arranged on the outside of the rotating gear 13 and the horizontal moving gear 11 to protect the rotating gear 13 and the horizontal moving gear 11; the generator room 7 is connected to the gear sliding cabin 9.

[0035] The fifth embodiment of the present invention is substantially the same as the fourth embodiment, mainly in that: Fig. 9 As shown, the magnetic suspension piston 1 is arranged in a single configuration, the generator chamber 7 is located on one side of the magnetic suspension piston 1 , and a bracket is provided to fix the magnetic suspension piston 1 and the generator chamber 7 to the magnetic suspension piston connecting beam 16 .

[0036] The sixth embodiment of the present invention is substantially the same as the fourth embodiment, mainly in that: Fig.10 As shown, the magnetic suspension piston 1 is connected to the gravity base 15 through a rotating table 18, and a flow direction measuring instrument 19 is arranged on the rotating table 18. The flow direction measuring instrument 19 determines the wave flow direction in real time, sends a communication signal to the rotating table 18, and the rotating table 18 is started to adjust the direction of the magnetic suspension piston 1 so that the water thrust plate 102 faces the wave flow direction.

[0037] Preferably, a flow direction measuring instrument 19 is also installed on the rotating table 18 to ensure that the flow direction can be measured and the rotating table 18 can be controlled to rotate so that the magnetic suspension piston 1 faces the flow direction of the liquid.

[0038] The seventh embodiment of the present invention is substantially the same as the fourth embodiment, mainly in that: Fig.11 As shown, the magnetic suspension piston 1 is installed in a multi-stage series manner, that is, the magnetic suspension piston 1 is arranged back to back (the piston water flow inlet 5 of the front magnetic suspension piston 1 is arranged forward, and the piston water flow inlet 5 of the rear magnetic suspension piston 1 is arranged backward), and the length direction of the magnetic suspension piston 1 is arranged perpendicular to the wave flow direction, so as to make full use of the reciprocating motion of the wave flow. When the wave flow rises, it pushes the magnetic suspension piston 1 in front to generate electricity, and when the wave flow falls, it pushes the magnetic suspension piston 1 in the back to generate electricity.

[0039] The eighth embodiment of the present invention is substantially the same as the fourth embodiment, mainly in that: Fig.12 As shown, the magnetic suspension piston 1 is installed in a multi-layer stacked manner, that is, it is made of a plurality of magnetic suspension pistons 1 stacked and arranged. When in use, the device is arranged in a herringbone shape along the coastline, and the piston water flow inlet 5 of the magnetic suspension piston 1 is arranged toward the direction of the wave current. This embodiment is specially arranged for the coastal area with turbulent waves and is also used as a wave-breaking block. When the wave current hits the device, the multi-layer magnetic suspension piston 1 can increase the contact area with the wave current and reduce the wave current energy. Through the herringbone arrangement, the wave current is reflected and consumed between the devices, further reducing the wave current energy.

[0040] The main application place of the present invention is the sea area. When in use, the gravity foundation 15 is first sunk in the target sea area, and the lower surface of the gravity foundation 15 is sunk into the bearing layer by hammering, and the height of the upper surface of the gravity foundation 15 above the mud surface is greater than the maximum scour height. After the power generation device is installed, scour protection is done around the gravity foundation 15; when the water flow velocity in the sea area where the gravity foundation 15 is sunk is too large and the gravity foundation 15 cannot be fixed, a pile foundation is arranged on the bottom surface of the gravity foundation 15, and the gravity foundation 15 is fixed by the friction force of the pile foundation. After the gravity foundation 15 is installed, two magnetic suspension pistons 1 are arranged in parallel on the gravity foundation 15. The two magnetic suspension pistons 1 are connected by a plurality of horizontal connecting rods 4. The two ends of the horizontal connecting rods 4 are respectively provided with diagonal support connecting rods 3. The ends of the two diagonal support connecting rods 3 away from the horizontal connecting rods 4 are connected to the same position at the bottom of the deck 6. The horizontal connecting rods 4 and the two diagonal support connecting rods 3 form a triangular closed figure to improve the structural strength. When working, the wave flow enters the piston through the water inlet 5 of the magnetic suspension piston, and the water flow pushes the water flow thrust plate 102 to push the moving magnet fixing plate 107 along the force transmission shaft 103. The movable magnet fixed plate positioning axis 109 moves toward the fixed plate 1013. When the wave current decreases, the movable magnet fixed plate 107 is moved away from the fixed plate 1013 along the movable magnet fixed plate positioning axis 109 through the principle of like-charge repulsion between the fixed magnet 1011 and the movable magnet 1010. Then, the water flow thrust plate 102 is pushed toward the direction of the water flow inlet 5 of the magnetic suspension piston through the force transmission axis 103. At this time, a complete reciprocating motion of the magnetic suspension piston 1 is completed. During the reciprocating motion of the magnetic suspension piston 1, the power is generated by transmitting the power to the generator 12 through the horizontal moving gear connecting axis 108.

[0041] Wave and current loads can be calculated as follows: , Where: ρ w is the density of seawater, C w is the resistance coefficient, A is the projected area of ​​the component perpendicular to the direction of the ocean current, V is the ocean current velocity.

[0042] The mutual repulsion between two magnets can be calculated as follows: , Where: k is the electrostatic force constant, Q 1 , Q 2 For the magnetic force of the magnet, R is the distance between the two magnets.

[0043] Wave and current loadf w Just follow the current speed V The mutual repulsion between the two magnets changes with the change of f q It will only change with the distance between the two magnets. R Change and change.

[0044] Therefore, when the ocean current is generated and the ocean current velocity begins to increase, the ocean current load is generated. f q > f w , the ocean current load causes the magnetic suspension piston to start moving to the left, and the distance between the two magnets R Reduce, R Reduce f q Start to increase until f w = f q The moment when the moving direction of the magnetic suspension piston changes. The following two situations will occur: (1) When the current velocity begins to decrease f w As it decreases, f w < f q The mutual repulsive force between the two magnets causes the magnetic suspension piston to reverse direction and begin to move to the right.

[0045] (2) When the current speed continues to increase f w As it increases, the distance between the two magnets R Continue to decrease f q As it increases, f w , f q The increment is the same, f w = f q Continue to maintain equality, the magnetic suspension piston moves and the position remains unchanged, which only happens at an instant.

[0046] As long as the current speed V is a changing value, which will inevitably break the balance point of the magnetic suspension piston device and cause the magnetic suspension piston to move.

[0047] Thus, the present invention: 1. The wave current energy is used to drive the generator through the piston to directly generate electricity. Compared with the existing wave current energy power generation equipment, it reduces the transmission steps and reduces the energy loss.

[0048] 2. The reciprocating motion of the magnetic suspension piston is completed by setting a water thrust plate, a piston shell wall, a fixed magnet and a moving magnet in coordination with each other and utilizing the periodicity of wave motion.

[0049] 3. Fix the generator by setting up a generator fixing frame to ensure normal operation; provide a working environment for the generator by setting up a deck.

[0050] 4. By setting the horizontal moving gear and the horizontal moving gear connecting shaft, the movement effect of the magnetic suspension piston is transmitted to the generator to complete the power generation work.

[0051] 5. By setting up a rotating table and a flow direction measuring instrument, the flow direction of the wave current is determined in real time by the flow direction measuring instrument, and the direction of the magnetic suspension piston is adjusted by the rotating table so that the water thrust plate always faces the wave current direction to ensure maximum power generation efficiency.

[0052] 6. Using a gravity-based base, the entire power generation equipment is sunk to the seabed to perform power generation operations. Compared with traditional wave and current power generation devices, it is not restricted by sea areas and can be used in sea areas of different water depths.

[0053] 7. The intermittent wave and current power generation is adopted, and the entire power generation equipment is sunk to the seabed. There is no need to equip the mooring system, floating system and stabilization system of the traditional wave and current power generation device, thereby significantly reducing the project investment and having high economy and practicality.

[0054] 8. The overall structure can be prefabricated on shore, reducing the construction progress.
