Description

Technical Field

[0001] The invention belongs to the technical field of wind power generation, and in particular relates to a semi-rigid floating multi-energy hybrid power generation platform. Background Art

[0002] The ocean is the largest energy field on the earth's surface. Offshore new energy has become an important development direction for major maritime countries in the world to promote green and low-carbon energy transformation. At present, there are endless technical means to use offshore energy for power generation. The more common ones are offshore photovoltaic power generation, offshore wind power generation and wave power generation.

[0003] The use of offshore solar energy requires the use of photovoltaic panels. In addition to relying on solar power generation, photovoltaic panels also need to overcome the impact of the harsh offshore environment. Densely arranged photovoltaic modules using a rigid support structure system may be damaged by large waves, and the rigid support structure system has poor structural efficiency and poor economy. Although the use of a flexible support structure system can effectively improve structural efficiency and reduce deadweight, the pure flexible support structure system has poor redundancy, and the system is prone to failure in windy and rough sea conditions, and has poor safety. Wind power generation needs to consider the wind direction at sea, and a fixed installation angle cannot fully exert the effect of wind power generation. Similarly, wave energy generation requires the impact of waves, and cannot be fully utilized when the sea is calm.

[0004] At present, there are some offshore power generation technologies, each with its own characteristics, such as the buoy-type offshore power generation platform (patent number CN201310455060.8), which consists of different wind power generation boxes, solar power generation boxes, ocean current power generation boxes and energy storage boxes. The boxes are connected by bolts, and the power generation system is modularized, which is convenient for installation and disassembly. However, the multi-box connection method is prone to structural instability. At the same time, each power generation equipment has not designed a corresponding anti-extreme weather structure. When the wind and waves are large, its stability is difficult to guarantee. Patent number CN201510441268.3 discloses an offshore wind energy and ocean wave energy combined power generation device. This power generation device consists of a wind turbine and a wave energy generator. The wind turbine platform support body passes through the upper platform and the lower platform to connect, and a hydraulic cylinder is arranged between the upper platform and the lower platform to absorb wave energy for power generation. This power generation device improves resource utilization to a certain extent, but the wind turbine support body is relatively high, and the horizontal axis wind turbine has a large overturning force, which will increase the requirements for the structural strength and stability of the platform, thereby increasing the cost.

[0005] Based on the above situation, there is still room for improvement in how to make full use of offshore energy for hybrid power generation. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0077] Example 1, see Figure 1 , Figure 2 As shown, this embodiment discloses a semi-rigid floating multi-energy hybrid power generation platform, including a main frame 1, a wave energy power generation module 2, a floating body module 3, a photovoltaic power generation module 4, a wind power generation module 5 and an adaptive wind direction adjustment mechanism.

[0078] The main frame 1 is surrounded by a plurality of frame frames, and a plurality of transverse beams 13 arranged in parallel transversely and a plurality of longitudinal beams 14 arranged in parallel longitudinally are connected inside the main frame 1. The transverse beams 13 and the longitudinal beams 14 are arranged alternately, and installation openings are formed by enclosures between adjacent transverse beams 13 and longitudinal beams 14. Therefore, a plurality of alternately arranged transverse beams 13 and longitudinal beams 14 can be enclosed to form a plurality of installation openings.

[0079] In some embodiments, there are multiple photovoltaic power generation modules 4, and the number of photovoltaic power generation modules 4 is set in a one-to-one correspondence with the number of installation openings. A photovoltaic power generation module 4 can be movably set in each installation opening, and the photovoltaic power generation module 4 can convert solar energy into electrical energy.

[0080] There are multiple floating modules 3 , which are arranged below the main frame 1 and connected to the main frame 1 . The floating modules 3 are used to provide buoyancy for the main frame 1 .

[0081] There are multiple wind power generation modules 5, and the wind power generation modules 5 are respectively arranged on the main frame 1. The wind power generation modules 5 are used to convert wind energy into electrical energy.

[0082] A plurality of wave energy power generation modules 2 can be provided, and a mounting work plate 12 is provided on the main frame 1, and the wave energy power generation module 2 is provided at the lower end of the mounting work plate 12. The wave energy power generation module 2 can convert wave energy into electrical energy.

[0083] The adaptive wind direction adjustment mechanism is arranged on the main frame 1 and connected to the wind power generation module 5. The adaptive wind direction adjustment mechanism is used to drive the fixed inner tube 52 of the wind power generation module 5 to rotate around the vertical axis according to the offshore wind direction, thereby adjusting the direction of the impeller of the wind power generation module 5. Blades are installed on the impeller, so that no matter how the wind direction changes, the sea breeze can drive the blades of the wind power generation module 5 to rotate to generate electricity.

[0084] The semi-rigid floating multi-energy hybrid power generation platform of this embodiment can fully utilize marine resources for power generation in offshore operations through the hybrid power generation of solar energy, wind energy and wave energy, and can improve the efficiency of offshore energy development and utilization.

[0085] A number of transverse beams arranged in parallel transversely and a number of longitudinal beams arranged in parallel longitudinally are connected inside the main frame, and a number of installation openings are formed by enclosures between adjacent transverse beams and longitudinal beams. Each installation opening can be equipped with a photovoltaic power generation module to ensure that the photovoltaic power generation module can not only maintain stable operation in the harsh marine environment, but also ensure the uniformity of the photovoltaic power generation panel in a calm environment, ensure the mobility of the photovoltaic power generation panel while ensuring that the photovoltaic power generation panel will not deviate from the restrictions of the main frame.

[0086] By setting up an adaptive wind direction adjustment mechanism, the wind power generation module can be adaptively adjusted according to the offshore wind direction during operation, making full use of the ocean wind resources.

[0087] The wave power generation module cooperates with the floating module during operation to adapt to different marine environments and make full use of ocean wave resources.

[0088] In some embodiments, such as Figure 2-Figure 4 As shown, the photovoltaic power generation module 4 includes a support frame 41 , an elastic support member 42 and a mounting frame 43 .

[0089] The support frame 41 is arranged along the inner side of the frame edge of the installation opening, and an elastic support member 42 is arranged on the support frame 41, and a mounting frame 43 is arranged on the elastic support member 42, and a photovoltaic power generation panel is arranged on the mounting frame 43. The mounting frame 43 is connected to the support frame 41 through the elastic support member 42. When the photovoltaic power generation panel is impacted by waves, the elastic support member 42 can be stretched or compressed in the direction of the impact force, which can buffer the impact force of the waves and prevent the waves from damaging the photovoltaic power generation panel.

[0090] In some embodiments, the elastic support member 42 is composed of two ball-angle chains and a spring telescopic rod, and the ball-angle chains are respectively arranged on the support frame 41 and the mounting frame 43.

[0091] In some embodiments, the non-adjacent corners of the mounting frame 43 and the main frame 1 protrude downward to form a support rod 431, and a through hole 411 is opened at a position of the support frame 41 corresponding to the support rod 431. The support rod 431 passes through the through hole 411 and protrudes to the bottom of the through hole 411, and a fixing portion is provided at the lower end of the support rod 431.

[0092] The photovoltaic power generation module also includes a cable 432, which has multiple sections, and two adjacent struts 431 in the transverse or longitudinal direction are connected by the cable 432, the cable 432 is fixed to the strut 431 through a fixing part, and the strut 431 adjacent to the main frame 1 is connected to the main frame through the cable 432.

[0093] The support rods 431 or the support rods 431 and the main frame 1 are connected by cables 432 and can be tensioned to generate prestress, thereby forming a cable-supported structural system.

[0094] The cable support structure system formed by the cooperation between the cable 432 and the elastic support member 42 can effectively improve the structural efficiency of the platform while ensuring the redundancy of the platform structure, ensuring the economy and safety of the platform, and improving the stability of the photovoltaic panels working at sea.

[0095] By adopting the above technical scheme, in a harsh marine environment, when waves impact a photovoltaic power generation panel at a certain position, the impacted photovoltaic power generation panel is adjusted in the direction of the force with the assistance of the elastic support member 42, which can alleviate the impact of the waves on the photovoltaic power generation panel and reduce the damage caused by the wave impact. Considering the irregularity of the ups and downs of the waves at sea, the power generation panels of each installation port are connected by the elastic support member 42 to ensure that the photovoltaic power generation panels set on the main frame 1 will not be damaged by the impact of waves. The cables used in the present invention are elastic and stable to ensure the overall unity of the photovoltaic power generation panels on the mounting frame 43. The mutual cooperation between the elastic support member 42 and the cable 432 ensures the flexibility of the photovoltaic power generation panel in the marine environment during operation. In addition, the mounting frame 43 and the support frame 41, with the assistance of the elastic support member 42 and the cable 432, ensure that the overall power generation platform will not deviate from the rigidity of the main frame 1, that is, it can ensure the overall stability of the hybrid power generation platform working at sea while ensuring the flexible adjustment of the photovoltaic power generation panel at sea.

[0096] In some embodiments, such as Figure 1 , Figure 4-Figure 8 As shown, a mounting base 11 is provided on the main frame 1 , and the wind power generation module 5 includes a fixed sleeve 51 , a fixed inner tube 52 and an impeller 53 .

[0097] The fixed sleeve 51 is arranged on the mounting base 11, and the fixed inner tube 52 is arranged in the fixed sleeve 51, and the fixed inner tube 52 is connected to the fixed sleeve 51 through a bearing. The upper end of the fixed inner tube 52 protrudes to the outside of the fixed sleeve 51, and the mounting base 11 is provided with a mounting hole coaxial with the fixed inner tube 52.

[0098] The impeller 53 is fixedly connected to the upper end of the fixed inner tube 52, the lower end of the fixed inner tube 52 passes through the mounting hole and protrudes between the mounting base 11 and the main frame 1, and the fixed inner tube 52 is connected to the mounting base 11 through a bearing. The fixed inner tube 52 can rotate in the fixed sleeve 51 when driven by an external force, thereby driving the impeller 53 to adapt to the offshore wind direction for power generation.

[0099] The wind power generation module 5 further includes a locking mechanism 56 for locking the fixed inner tube 52 when the fixed inner tube 52 is rotated to a target position.

[0100] In some embodiments, the locking mechanism 56 includes a lifting execution column 561 , a locking rod 562 , and a lifting member 55 .

[0101] The lifting and lowering actuator column 561 is arranged in the tube of the fixed inner tube 52 and extends in the length direction of the fixed inner tube 52. The outer surface of the lifting and lowering actuator column 561 is formed with a control groove 5611 extending in the length direction thereof. The control groove 5611 includes a locking section 56111, a transition section 56112 and an unlocking section 56113. The locking section 56111 has the shallowest depth, and the unlocking section 56113 has the deepest depth. The transition section 56112 is connected between the locking section 56111 and the unlocking section 56113. A penetrating locking hole 521 is opened on the tube wall of the fixed inner tube 52, and a fixing hole 511 is opened on the inner wall of the fixed sleeve 51 along its circumference.

[0102] The locking rod 562 is arranged in a one-to-one correspondence with the control groove 5611 , the inner end of the locking rod 562 is slidably arranged in the control groove 5611 , and the outer end of the locking rod 562 is inserted into the locking hole 521 and aligned with the fixing hole 511 .

[0103] The lifting member 55 is arranged between the mounting base 11 and the main frame 1 and supported on the main frame. The lifting member 55 is fixed to the bottom of the lifting execution column 561 and is used to drive the lifting execution column 561 to perform lifting and lowering movements. When the locking rod 562 slides to the locking section 56111 of the control groove, the bottom of the locking section 56111 squeezes the locking rod 562 in the horizontal direction, and the outer end of the locking rod 562 penetrates into the fixing hole 511 to lock the fixed inner tube 52 and the fixed sleeve 51, so that the fixed inner tube 52 cannot rotate, thereby locking the current direction of the impeller. When the locking rod 562 slides to the unlocking section 56113 of the control groove, the unlocking section 56113 pulls the locking rod 562 back, and the outer end of the locking rod 562 retreats from the fixing hole 511 to the locking hole 521, so as to unlock the fixed inner tube 52 and the fixed sleeve 51. At this time, the fixed inner tube 52 can be driven to rotate according to the current wind direction.

[0104] In some embodiments, such as Figure 6 , Figure 7As shown, the control groove 5611 is formed with limiting grooves 5612 on both sides thereof, and the notches of the limiting grooves 5612 are opened toward the control groove 5611. The inner end of the locking rod 562 is provided with limiting structures, and the limiting structures extend toward both sides and respectively penetrate into the limiting grooves 5612. When the lifting actuator column 561 performs lifting motion, the locking rod 562 slides in the control groove 5611, and the limiting groove 5612 can realize push-pull motion by the limiting structure when the locking rod 562 slides to different depth positions of the control groove 5611.

[0105] By adopting the above technical solution, during operation, the fixed inner tube 52 is controlled to rotate, and the fixed inner tube 52 adjusts the impeller 53 to an angle that matches the offshore wind direction during operation, and then the lifting member 55 drives the locking mechanism 56 to work, so that the fixed inner tube 52 and the fixed sleeve 51 are in a fixed and locked state. Through the above operation, not only can the offshore wind resources be fully utilized and the working angle of the impeller 53 be automatically adjusted, but the position of the adjusted impeller 53 can also be fixed and locked to ensure the stability of the wind power generation operation.

[0106] In some embodiments, the lifting component 55 includes a lifting cylinder 551 and a lifting work frame 552 .

[0107] The lifting cylinder 551 is supported on the main frame 1. The lifting frame 552 is arranged on the lifting cylinder 551, and the bottom of the lifting execution column 561 is connected to the lifting frame 552. The lifting cylinder 551 drives the lifting frame 552 to move up and down, and then drives the lifting execution column 561 to move up and down, and finally realizes the locking or unlocking of the locking mechanism 56.

[0108] In some embodiments, the adaptive wind direction adjustment mechanism includes a wind direction detection module (not shown in the figure for angle reasons) and a control motor. The wind direction detection module is used to detect the offshore wind direction and send it to the control module. The control module generates a control signal for the control motor according to the wind direction. The control motor receives the control signal and drives the fixed inner tube to rotate around the axis to adjust the direction of the impeller.

[0109] In some embodiments, a plurality of control motors may be provided, and each adaptive wind direction adjustment mechanism may be provided with a control motor to adjust the direction.

[0110] In order to reduce the cost, in some embodiments, the control motor has one, which is arranged at one corner of the main frame 1.

[0111] like Figure 9-11 As shown, the adaptive wind direction adjustment mechanism further includes a worm gear 61 , a driving bevel gear 62 , a rotating shaft 63 , a driven bevel gear 64 , a control sprocket 65 and an auxiliary sprocket 66 .

[0112] The driving bevel gear 62 is connected to the output shaft of the control motor, and the control motor can directly drive the driving bevel gear 62 to rotate.

[0113] There are two driven bevel gears 64 , and the two driven bevel gears 64 are meshed and connected with the driving bevel gear 62 respectively.

[0114] There are two rotating shafts 63 , and the two rotating shafts 63 are fixedly connected to the two driven bevel gears 64 in a one-to-one correspondence. The two rotating shafts 63 extend along the transverse direction and the longitudinal direction of the main frame 1 , respectively. A plurality of worm parts 631 are provided on the rotating shafts 63 .

[0115] Based on the distribution state of the above-mentioned rotating shafts 63, they can be used as driving sources for rotating the fixed inner tubes 52 arranged in both vertical and horizontal directions during operation.

[0116] The worm wheel 61 and the worm portion 631 are disposed in a one-to-one correspondence, and the worm wheel 61 is meshed with the corresponding worm portion 631 .

[0117] The control sprocket 65 is fixedly connected to the worm gear 61 in a one-to-one correspondence.

[0118] The auxiliary sprocket 66 is arranged on a side of the main frame 1 opposite to the control sprocket 65 . The auxiliary sprocket 66 is arranged on the main frame 1 via a bearing. The auxiliary sprocket 66 and the control sprocket 65 are connected in transmission via a chain 67 .

[0119] The driven sprocket 54 is fixed to the lower end of the fixed inner tube 52 and is coaxially arranged with the fixed inner tube 52 . The driven sprocket 54 is arranged between the control sprocket 65 and the auxiliary sprocket 66 and is meshed with the chain 67 .

[0120] By adopting the above technical solution, when the angle of the impeller 53 needs to be adjusted according to the offshore wind direction during operation, the lifting cylinder 551 is in a retracted state, and the fixed inner tube 52 can rotate in the fixed sleeve 51. In this state, the control motor is started, and the control motor controls the active bevel gear 62 to rotate. The active bevel gear 62 synchronously controls the two driven bevel gears 64 to rotate synchronously during the movement, thereby synchronously controlling the two rotating shafts 63 to rotate. During the rotation of the rotating shaft 63, the worm part 631 on the rotating shaft 63 is driven to rotate through the mutual cooperation between the worm wheel 61 and the worm part 631. The worm part 631 drives the worm wheel 61 to rotate, and the control sprocket 65 set on the worm wheel 61 rotates with the worm wheel 61, and then the control sprocket 65, the auxiliary sprocket 66, the driven sprocket 54 and the chain 67 cooperate with each other to drive the fixed inner tube 52 to rotate and adjust. This solution can realize the use of one control motor to drive multiple adaptive wind direction adjustment mechanisms to act at the same time.

[0121] In some embodiments, such as Fig.12As shown, the floating module 3 includes a supporting work frame 31 arranged on the main frame 1, an air pipe 32 is fixed on the supporting work frame 31 along its circumference, buoys 33 are arranged on the supporting work frame 31 at equal intervals, and a rubber air bag 34 is arranged on the supporting work frame 31 between adjacent buoys 33. A waterproof sealed box is arranged on the supporting work frame 31, and an air pump is arranged in the waterproof sealed box, and the air pump is connected to the air pipe 32.

[0122] By adopting the above technical solution, during operation, the buoyancy is provided for the hybrid power generation platform of the present invention through the cooperation between the float 33 and the rubber airbag 34. The air pump can control the degree of inflation of the rubber airbag 34 during this process. After the rubber airbag is inflated, it can not only ensure the floating stability of the hybrid platform, but also in the absence of waves, the repeated changes in the degree of inflation of the rubber airbag controlled by the air pump enable the wave energy power generation module to operate smoothly.

[0123] 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.
