Description

Technical Field

[0001] The present invention belongs to the technical field of wind power or hydraulic power generation, and in particular, relates to a wave adaptive multi-energy hybrid power generation platform system. Background Art

[0002] Energy is an important material resource that supports human production and life. However, for a long time, human beings' over-reliance on coal and oil has led to a sharp decrease in coal and oil reserves, which are almost exhausted. This over-exploitation has also caused the rapid deterioration of the earth's environment. In order to meet this challenge, marine clean energy such as wind energy, solar energy and wave energy are particularly important. my country has a long coastline and many islands, and marine clean energy is very abundant. By effectively using marine clean energy to generate electricity, it can not only improve human energy structure and reduce dependence on coal and oil, but also help promote the sustainable development of marine resources. Therefore, how to effectively use marine clean energy has become crucial.

[0003] Existing floating power generation platforms, such as the Chinese patent with announcement number CN205744290U, disclose a floating wind-solar-wave integrated power generation platform, including a floating platform and a support column placed in the center of the floating platform, a wind power generation device is provided at one end of the support column, and a ballast tank is provided at the other end of the support column, and an energy management control system and a power transmission system are provided in the ballast tank; a solar photovoltaic power generation device is provided on the floating platform, and a number of wave power generation devices are evenly arranged on the side wall of the floating platform; the floating platform is connected to the anchor on the seabed through a tension cable; the wind power generation device, the solar photovoltaic power generation device, and the wave power generation device are connected to the power transmission system through the energy management control system, and the power transmission system transmits the electric energy of the wind power generation device, the solar photovoltaic power generation device, and the wave power generation device to the land power grid. This patent integrates the wind power generation device, the solar power generation device, and the wave power generation device together, and its structure is simple and stable to use, which can solve the problem of "discontinuous power" output of the existing power generation device.

[0004] In the above technology, power generation is mainly carried out by placing three types of power generation devices at various positions on the floating platform, but the stability of the floating platform in the sea water is not fully considered. Due to the harsh offshore environment and the high winds and waves, the above floating platform is prone to capsizing when placed in the sea water. In addition, the impact of the marine environmental load can easily cause damage to the floating platform and the structure above it. Even if the above floating platforms are connected in an array, the range of movement of the connection nodes between the floating platforms is limited, making it difficult to cope with various working conditions in the ocean. In addition, the floating platforms are prone to collision with each other under the action of waves, and the above floating platforms are not equipped with side protection structures.

[0005] Based on the above situation, there is still room for improvement in the existing floating power platform technology. Summary of the invention

[0057] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0058] Embodiment 1: This embodiment proposes a wave adaptive multi-energy hybrid power generation platform system, such as Figure 1-Figure 3 As shown, it includes a base unit 1, a wind energy photovoltaic module 2, a wave energy module 3, a buffer component 4 and a hinge 5.

[0059] The base unit 1 is a hexahedral structure with parallelogram end faces at both ends, and the sharp edges of a plurality of base units are hinged in sequence to form a platform body.

[0060] Buffer components 4 are respectively arranged on the inclined surfaces on both sides of the base unit 1 , and the buffer components 4 can perform telescopic movement along the normal direction of the inclined surface where they are located, so as to buffer the collision between adjacent base units 1 .

[0061] The sharp edges of several base units 1 are hinged in sequence through hinges 5 to form a platform body, and the hinges 5 are used to push the buffer assembly 4 outward when the two base units connected to it rotate, thereby being able to buffer the collision between adjacent base units 1.

[0062] The wave adaptive multi-energy hybrid power generation platform system of this embodiment is based on the base unit 1. Relative to the sea surface, the wind energy photovoltaic module 2 is installed on the upper part of the base unit 1, and the wind energy photovoltaic module 2 uses solar energy and wind energy to generate electricity. The wave energy module 3 is installed on the lower part of the base unit 1. The wave energy module 3 uses the relative movement between adjacent base units 1 to generate electricity, which complements the power generation of the wind energy photovoltaic module 2 (in different time periods, timely power generation can be carried out through one or more of wind energy, wave energy and solar energy, and there will be no situation where no power generation occurs in some time periods. For example, on windy and cloudy days, when the environment is in a state of strong winds and waves, wind energy + wave energy power generation is mainly used, and solar energy power generation is supplemented. When encountering different environments, targeted power generation can be carried out, so that wind energy, solar energy and wave energy complement each other, the total power generation is increased, and the cost recovery time is shortened).

[0063] In order to improve the stability of the platform system, a base unit 1 with a hexahedral structure and parallelogram end faces at both ends is proposed. The sharp edges of several base units 1 are hinged in sequence through hinges to form a platform body, realizing high-position hinge and low-position hinge connection between the base units 1, forming a platform body that can move unidirectionally with the waves in the main wave direction.

[0064] In order to prevent the possibility of collision between adjacent base units 1, an extrusion-type buffer structure (buffer component 4) is provided, and the buffer component 4 is used to provide edge buffer protection between adjacent base units 1 to prevent collision.

[0065] When the base unit 1 in this embodiment is placed on the sea, the base units 1 are connected by rotating the longitudinal surfaces and sliding up and down, so that they can adapt well to the direction of the main waves, thereby improving the stability of the base unit 1. At the same time, during the process of the inclined surfaces of the base units 1 approaching each other, the internal structure of the buffer assembly 4 is squeezed mutually so that the inclined surface of the base unit 1 extends out of the buffer structure, providing a certain buffer protection for the adjacent base units 1, reducing the possibility of damage to the surface of the base unit 1 and internal damage to the wind photovoltaic module 2 and the wave energy module 3 caused by collision. The present invention adopts the base unit 1 + buffer assembly 4 + hinge 5, which improves the possibility of coordinated movement between the platform system and the waves, reduces the load borne by the platform structure, and improves the safety of the platform structure.

[0066] In some embodiments, the base unit 1 adopts a hexahedral structure with parallelogram end faces at both ends, a circular groove 11 is opened along the length direction on the acute-angled edges of the base unit 1, a hidden groove 12 is opened on the inclined surfaces on both sides of the base unit, the buffer assembly 4 is arranged in the hidden groove 12, and a drainage cavity 6 connected to the hidden groove 12 is opened on one side of the hidden groove 12 in the base unit 1, and the other end of the drainage cavity 6 is connected to the outside, and a one-way valve 13 is arranged in the drainage cavity 6, and the one-way valve 13 is used to discharge the water in the hidden groove 12 to the outside through the drainage cavity 6 in one direction.

[0067] When the buffer assembly 4 is extended to perform a buffering protection movement, part of the seawater flows back into the hidden groove 12. In order to discharge this part of the seawater and enable the buffer assembly 4 to be retracted into the hidden groove 12, the present invention provides a drainage cavity 6, and when the buffer assembly 4 is retracted into the hidden groove, the seawater is discharged from the drainage cavity 6 by squeezing.

[0068] In some embodiments, a steel frame is provided below the base unit 1, and a floating module is provided at the bottom of the steel frame, and the floating module provides support for the base unit 1. Several base units 1 are formed into a whole through hinges 5, and finally fixed to the mooring system (such as Figure 8 As shown, the mooring system is mainly used to confine the platform system within a specific range. The platform system is confined within a certain range by the traction of the anchor chain in the mooring system). This type is suitable for deeper waters.

[0069] In some embodiments, reference Figure 4-Figure 6 As shown, in order to prevent collision between adjacent base units 1 during rotation, the present invention is provided with a buffer assembly 4 having a buffer structure. A guide cavity 14 is also provided in the base unit 1, which is connected to the hidden groove 12 and the circular groove 11 respectively.

[0070] The buffer assembly includes a connecting shaft 41, a resistance increasing part 42, a sliding member 43, a connecting rod 44, an extrusion disc 45, an extrusion part 46 and a buffer part 47. The connecting shaft 41 is rotatably arranged inside the circular groove 11, and the connecting shaft 41 is fixedly connected to the hinge 5.

[0071] The resistance increasing portion 42 is fixed on the connecting shaft 41 , and an arc track 421 extending along the circumferential direction of the connecting shaft is formed in the resistance increasing portion 42 , and a sliding member 43 is slidably arranged in the arc track 421 .

[0072] The connecting rod 44 is disposed in the base unit 1 , and one end of the connecting rod 44 is disposed toward the circular groove 11 , and the other end is disposed toward the guide cavity 14 . The outer end of the sliding member 43 protrudes to the outside of the arc track 421 and is connected to the connecting rod 44 .

[0073] The buffer portion 47 is slidably disposed in the hidden groove 12. At least one side of the connecting rod 44 is slidably provided with a pressing portion 46, which is used to push the buffer portion 47 toward the outer side of the hidden groove 12 when sliding toward the guide cavity 14.

[0074] The extrusion disk 45 is fixed to the connecting shaft 41 , and is used to press the extrusion portion 46 to slide toward the guide cavity 14 when the hinge 5 drives the connecting shaft 41 to rotate toward the buffer portion 47 .

[0075] When the adjacent base units 1 gradually rotate and approach the buffer portion 47 , the buffer portion 47 is squeezed by the squeezing portion 46 and extends out of the hidden groove 12 to enter a buffer protection state.

[0076] In order to improve the uniformity of the squeezing force on the buffer portion 47 , it is preferred that there are two squeezing disks 45 , which are respectively disposed on both sides of the arc track 421 .

[0077] In some embodiments, the initially folded base unit 1 is spread out on the sea. Under the influence of waves, the base unit 1 rotates with the hinge 5. The resistance friction of the resistance increasing portion 42 on the sliding member 43 increases the difficulty of the base unit 1 changing its angle, so as to cope with smaller waves. For larger waves, it is difficult to reduce the angle change between the base unit 1 by the friction resistance between the resistance increasing portion 42 and the sliding member 43. Under the extrusion cooperation of the extrusion disc 45, the buffer portion 47 is gradually extended from the hidden groove by the extrusion portion 46. Under the action of waves, the base unit 1 rotates with the hinge 5. Whenever adjacent base units 1 are about to collide, the extruded and extended buffer portion 47 acts as a buffer protection structure to prevent the base units 1 from colliding. The present invention performs anti-collision design on the base unit 1 according to the wave conditions. For smaller waves, the present invention increases the difficulty of rotating the base unit 1 through friction resistance to improve its stability after being laid flat; for larger waves, the present invention increases the extrusion plate 45, the extrusion part 46 and the buffer part 47 while maintaining the friction resistance. Through the cooperation of the three, the buffer part 47 extends out of the hidden groove to act as a buffer protection structure to prevent collision between the base units 1.

[0078] Reference Figure 4-Figure 5 As shown, waves may be encountered during offshore operations. Regardless of the size of the waves, the base unit 1 provided in the present invention will follow the waves to perform longitudinal rotation, so that the base unit 1 is always in a state of up and down swinging, and the stability is poor. In order to improve its stability, the present invention is provided with a resistance increasing part 42. When encountering light wind and small waves, the resistance increasing friction between the resistance increasing part 42 and the sliding part 43 can reduce the degree of rotation of the base unit 1 and improve its stability.

[0079] In order to further increase the resistance of the resistance increasing part 42 to cope with larger wind and waves, in some embodiments, the resistance increasing part further includes a resistance increasing ball 422, which is arranged on one side of the arc track 421 close to the connecting rod 44. There are multiple resistance increasing balls 422, which are respectively connected to the inner wall of the arc track 421 through elastic members. The elastic member always maintains the tendency to push the resistance increasing ball 422 outward, and the sliding member 43 is slidably arranged in the arc track 421. When the sliding member 43 slides in the arc track 421, the resistance increasing ball 422 increases the sliding difficulty of the sliding member 43.

[0080] In some embodiments, reference Figure 4-Figure 5 As shown, the distance between the inner track of the arc track 421 and the axis position of the connecting shaft 41 is always equal from the back to the front, the sliding member 43 moves on the arc track 421 at an equal diameter distance, and the resistance-increasing balls 422 arranged in the arc track 421 on one side are arranged in an arc shape, and the distance between the resistance-increasing balls 422 and the axis position of the connecting shaft 41 gradually increases from the middle to the sides. The distance between the arc-shaped resistance-increasing balls 422 and the axis position of the connecting shaft 41 increases from the middle to the sides in order to increase the difficulty of the base unit 1 to rotate (the greater the rotation angle, the greater the resistance), and ensure the stability of the base unit 1.

[0081] When encountering waves, the flattened base unit 1 has a tendency to rotate relative to each other. As the waves increase, under the elastic pressure of the elastic member and the resistance-increasing ball 422, it becomes increasingly difficult for the sliding member 43 to rotate.

[0082] In some embodiments, reference Figure 4-Figure 6 As shown, in order to prevent collision between adjacent base units 1 and cause structural damage, the present invention squeezes out the buffer portion 47 through the cooperation between the squeezing disk 45 and the squeezing portion 46, thereby avoiding collision between the base units 1 by means of advance buffering.

[0083] One side of the extrusion plate 45 close to the extrusion part 46 is an arc-shaped side, and the distance between the arc-shaped side of the extrusion plate 45 and the axial position of the connection shaft gradually increases from the end far from the buffer part to the end close to the buffer part. When the two hinged base units 1 gradually rotate toward the direction of the buffer part 47, the hinge 5 drives the connection shaft 41 to rotate, and then drives the extrusion plate 45 to rotate, and the contact point between the arc-shaped side of the extrusion plate 45 and the extrusion part 46 moves from the end far from the buffer part to the end close to the buffer part. The greater the relative rotation amplitude of the two base units 1, the greater the extrusion strength of the extrusion plate 45 on the extrusion part 46.

[0084] In some embodiments, reference Figure 5 As shown, the extrusion portion 46 includes a movable rod 461 , an extrusion member 462 , a clamping member 463 , a pressure-bearing member 464 , a compression spring 465 and an extrusion wheel 466 .

[0085] Combination Fig. 9 As shown, the movable rod 461 is slidably disposed on one side of the connecting rod 44 , and a sliding groove 4611 is defined in the movable rod 461 .

[0086] The extrusion member 462 is slidably disposed in the slide groove 4611, and a sliding wheel 481 is disposed at one end of the extrusion member 462 close to the connecting shaft 41, and the sliding wheel 481 is disposed corresponding to the arc-shaped edge of the extrusion plate 45, and an extrusion head 467 is disposed at the other end of the extrusion member 462. The arc-shaped edge of the extrusion plate 45 extrudes the extrusion member 462 by extruding the sliding wheel 481.

[0087] Locking holes are symmetrically provided on the inner walls on both sides of the slide groove 4611, and the clamping part 463 includes locking pins 4631 corresponding to the locking holes one by one, and the locking pins 4631 extend into the corresponding locking holes. The locking pins 4631 are connected to the pressure-bearing part 464, and the pressure-bearing part 464 is located in the slide groove 4611. The two pressure-bearing parts 464 are connected by a compression spring 465, and the compression spring 465 is coaxially arranged with the two locking pins 4631. The pressure-bearing part 464 extends toward one end of the extrusion part 462 to form a pressure plate 4632, and the pressure plate 4632 extends obliquely from the pressure-bearing part 464 toward the central axis direction of the slide groove 4611. In the normal state, the free end of the extrusion head 467 is located between the pressure plate 4632 and the inner wall of the slide groove 4611.

[0088] Under normal conditions, the lock pin 4631 is inserted into the lock hole, and the extrusion part 46 is locked. When the arc edge of the extrusion disk 45 passes through the extrusion sliding wheel 481, the extrusion member 462 is pushed to move in the direction of the pressure-receiving member 464 in the slide groove 4611, and the extrusion head 467 squeezes the pressure plate 4632 along the track of the pressure plate 4632 toward the center direction of the slide groove 4611. The pressure plate 4632 drives the pressure-receiving member 464 to move toward the center direction of the slide groove 4611, compressing the compression spring 465, thereby driving the lock pin 4631 to withdraw from the lock hole into the slide groove 4611, and the extrusion part 46 is unlocked. When the extrusion force disappears, the restoring force of the compression spring 465 pushes the lock pin 4631 into the slide groove 4611 again, and the extrusion part 46 resumes locking.

[0089] In some embodiments, the surface of the compression spring 465 is coated with anti-rust oil.

[0090] The extrusion wheel 466 is located in the guide cavity 14 and is fixed to the end of the movable rod 461. When the extrusion part 46 is unlocked and continues to slide toward the guide cavity 14 under the extrusion force, the extrusion wheel 466 is used to push the buffer part 47 toward the outside of the hidden groove 12.

[0091] In some embodiments, the extrusion member 462 is connected to an elastic reset mechanism for resetting in the slide groove 4611 so that the extrusion portion 46 is locked again.

[0092] During the actual rotation process, the flat-laid base unit 1 rotates under the push of the waves. When there is little wind and waves, the stability of the base unit 1 is maintained only by the resistance of the sliding member 43 in the resistance-increasing portion 42. At this time, the sliding wheel 481 has just contacted the extrusion portion 46 and the extrusion member 462 gradually retracts back to the movable rod 461 under the action of the extrusion force, but the retracted part of the extrusion member 462 does not completely unlock the clip 463. At this time, the position of the movable rod 461 and the base unit 1 are not unlocked. As the waves increase, the rotation angle of the base unit 1 increases. At this time, the sliding wheel 481 comes to the second half of the extrusion portion 46, and the retracted part of the extrusion member 462 completely unlocks the clip 463, so that the movable rod 461 and the base unit 1 are unlocked. Then the movable rod 461, the extrusion member 462 and the extrusion wheel 466 move synchronously to further squeeze the buffer portion 47 outward, and the extended buffer portion 47 acts as a buffer structure. The base unit 1 in the present invention has two rotation angle directions, one is the rotation toward the inclined position of the base unit 1 (direction A), and the other is the rotation toward the plane position of the base unit 1 (direction B). The present invention sets a retractable buffer structure at the inclined position because the angle range of rotation of adjacent base units 1 in direction A is small, and the possibility of colliding with each other in this direction is high. Therefore, a buffer part 47 with better buffering performance is used, and the angle range with the other direction is one hundred and eighty degrees, and the possibility of collision between the two is low. Therefore, a buffer pad is used for buffering protection, which improves the targeting on the one hand and saves manufacturing costs on the other.

[0093] The upper and lower end surfaces of the base unit 1 are respectively provided with cushioning pads.

[0094] Reference Figure 5 As shown, in order to improve stability, the outer and inner parts of the pressure-bearing member 464 in the present invention are linear structures, and the spacing between the middle parts of the upper and lower pressure-bearing members 464 gradually decreases from the outside to the inside, and the front and rear are arranged into linear structures to serve as the transition area between the front and rear extrusion.

[0095] In some embodiments, reference Figure 4 and Figure 7 As shown, in order to further improve the buffering effect, the buffering portion 47 includes a hard frame 471 , an extrusion block 472 , a buffer layer 473 , a flexible edge layer 474 , a return spring 475 and a top support member 476 .

[0096] The hard frame 471 is slidably disposed in the hidden groove 12, and a squeezing block 472 is installed on the back of the hard frame 471, and the squeezing block 472 is inserted into the guide cavity 14, and a connecting spring is connected between the hard frame 471 and the hidden groove 12. The hard frame 471 always keeps a tendency to retract into the hidden groove 12.

[0097] One end of the buffer layer 473 is rotatably connected to the outside of the hard frame 471 , and the other end is connected to the hard frame via a flexible edge layer 474 . A return spring 475 is connected between the hard frame 471 and the buffer layer 473 .

[0098] The flexible edge layer 474 is used to prevent seawater from entering the interior of the buffer portion 47, and plays a flexible sealing effect and allows the buffer layer 473 to adjust the angle. A return spring 475 is connected between the hard frame 471 and the buffer layer 473, and the return spring 475 and the connecting spring are coated with an anti-rust and anti-corrosion layer.

[0099] The top support member 476 is installed in the hidden groove, and the top support member 476 passes through the through hole opened in the hard frame 471 and then extends into between the hard frame and the buffer layer, so as to support and limit the buffer layer 473. The top support member 476 supports and limits the buffer layer 473 in the initial position, preventing it from being concave when it is not extended.

[0100] During the process of the extrusion wheel 466 extruding the extrusion block 472, the hard frame 471 gradually extends out from the hidden groove. When adjacent base units 1 approach each other, they are buffered and protected by the buffer layers 473 connected to each other. When buffering, the buffer layer 473 uses the position of the hard frame 471 close to the hinge 5 as a rotation point, so that the buffer part 47 extends outward as a whole and can also become a triangular structure during the extrusion process. The angle change of the buffer layer 473 can better cope with the buffer protection after the base units 1 approach each other.

[0101] Reference Figure 4 As shown, in some embodiments, in order to further improve the coordinated movement between the base unit 1 and the waves, the hinge 5 includes a connecting member 51 and a detachable rod 52.

[0102] Combination Fig.10 As shown, the connecting member 51 includes two symmetrically arranged right-angled trapezoidal blocks 511, and the right-angled surfaces of the two right-angled trapezoidal blocks 511 are respectively formed with mutually cooperating sliding connection mechanisms 53, and the two right-angled trapezoidal blocks 511 can slide relative to each other in the vertical direction.

[0103] A vertical built-in spring is connected between the two right-angled trapezoidal blocks 511, and the built-in spring is coated with an anti-rust and anti-corrosion layer. The inclined surface of the connecting piece 51 is connected to one end of the detachable rod 52, and the other end of the detachable rod 52 is connected to the connecting shaft 41 by a locking piece.

[0104] The right-angled trapezoidal blocks 511 are arranged in an inverted manner with a short upper base and a long lower base.

[0105] During the actual operation, adjacent connecting members 51 slide against each other, so that the base unit 1 can rise and fall a short distance following the waves, thereby improving the coordination with the waves.

[0106] Working principle of the embodiment:

[0107] Step 1: unfold the folded and retracted (initial state) base unit 1 and lay it flat on the sea (water depth of more than 5 meters) for preliminary positioning, connect it to the mooring system after adjustment, and then generate electricity through the wind photovoltaic module 2 and the wave energy module 3;

[0108] Step 2: During offshore operations, the base units 1 are rotated to adapt to the main wave direction. When the base units 1 are about to approach each other, the internal structure of the buffer assembly 4 is mutually squeezed to make the inclined position of the base unit 1 extend out of the buffer structure, providing certain buffer protection for the adjacent base units 1.

[0109] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
