Description

Technical Field

[0001] The present invention belongs to the technical field of offshore wind power equipment and relates to an offshore wind power foundation with compressed air energy storage and a working method thereof. Background Art

[0002] Offshore wind energy has the characteristics of abundant resources, high power generation hours, large single-unit capacity, no land occupation and suitability for large-scale development, making it one of the important areas for the development of renewable energy.

[0003] However, offshore wind energy utilization is subject to constraints imposed by the ocean environment and seasonal factors, resulting in unstable wind speeds. Records show that a wind turbine is shut down approximately 30% of the time, operates at reduced capacity 40% of the time, and generates power at full capacity only 30% of the time. Because wind turbine power is determined by wind speed and cannot be adjusted arbitrarily based on grid load demand, this introduces significant instability into wind power grid integration. Therefore, integrating wind turbines with energy storage technology to reduce dependence on ambient wind speed is a future technological trend. Summary of the Invention

[0017] Preferably, the power generation component includes:

[0018] a first disc, wherein the first disc is coaxially fixed on the first rotating shaft, a plurality of first connecting rods are circumferentially provided on the outer side of the first disc, and the first ring is coaxially arranged on the outer side of the first disc via the plurality of first connecting rods;

[0025] A method for operating an offshore wind power foundation with compressed air energy storage comprises the following steps:

[0026] S1. When the wind and waves are strong, the wind drives the wind turbine on the tower to generate electricity, and at the same time drives the first rotor blades on the first shaft to rotate. The waves drive the second rotor blades on the second shaft to rotate in the same direction, and the rotating disk is driven to rotate clockwise through the rotating rod, so that the second generator generates electricity;

[0027] S2. Using the electricity generated by the second generator to drive the air compressor and cooler, the air compressor draws in air from the outside, and the cooler cools the compressed air and stores it in the air storage cavity of the steel foundation through the air intake pipe;

[0028] S3. When the wind and waves are small, the output power of the wind turbine on the tower decreases. At this time, the valve on the air outlet pipe is opened to release the compressed air in the air storage chamber, which drives the turbine to rotate and drive the first generator to generate electricity, so that the wind turbine maintains a stable output power;

[0029] S4. The first generator starts the electric heating tube in the tower to heat the inside of the tower, so that the gas released from the outlet pipe generates high temperature and high pressure, thereby improving the driving efficiency of the turbine.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] 1. When the offshore wind is strong, the wind turbine on the tower is driven to generate electricity. At the same time, the auxiliary power generation mechanism can also generate electricity. The generated electricity is used to drive the air compressor and cooler. The air compressor compresses the air, then uses the cooler to cool it down, and then transports it to the air storage cavity of the steel foundation through the air inlet pipe for storage. When the offshore wind is weak, the valve on the outlet pipe is opened, and the compressed air enters the turbine through the outlet pipe, driving the turbine to rotate, so that the first generator can generate electricity and maintain the output power of the wind power system. In addition, the compressed air can be released in time according to the load demand of the power grid to increase the output power of the wind power system and ensure the stable operation of the power grid.

[0032] 2. The air inlet pipe is wound downwardly around the outside of the tower. The surrounding seawater can assist in cooling the air, thereby improving the safety and stability of compressed air storage. When the compressed air is released, the electric heating wire in the electric heating pipe is activated to heat the tower, returning the compressed air in the air outlet pipe to a high temperature and high pressure state, thereby improving the propulsion efficiency of the turbine.

[0033] 3. When the wind and waves at sea are strong, the wind drives the first rotor blades on the first rotating shaft to rotate clockwise, and the waves drive the second rotor blades on the second rotating shaft to rotate in the same direction, causing the first disc and the second disc to rotate clockwise. The first connecting rod on the first disc drives the rotating rod and the rotating disc to rotate clockwise, causing the second generator to generate electricity. The rotation of the second connecting rod on the second disc does not affect the rotation of the rotating rod. The wind drives the first rotor blades on the first rotating shaft to rotate counterclockwise, and the waves drive the second rotor blades on the second rotating shaft to rotate in the same direction, causing the first disc and the second disc to rotate counterclockwise, and the second connecting rod on the second disc drives the rotating rod and the rotating disc to rotate clockwise, causing the second generator to generate electricity. The rotation of the first connecting rod on the first disc does not affect the rotation of the rotating rod. The second generator generates electricity to provide it to the air compressor and the cooler, which compresses and cools the outside air and stores it in the air storage chamber after compressing and cooling it. When the wind and waves at sea are small, the compressed air in the air storage chamber is released to drive the turbine to rotate, causing the first generator to generate electricity, thereby increasing the power generation of the wind power system at this time.

DETAILED DESCRIPTION

[0040] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0041] Example 1:

[0042] like Figure 1 、 2 As shown in Figure 4, an offshore wind power foundation with compressed air energy storage includes a tower 1, a steel foundation 2, a platform 4, an air storage cavity 21 and an auxiliary power generation mechanism.

[0043] The top of the tower 1 is connected to the tower body 3 , and the top of the tower body 3 is provided with a wind turbine.

[0044] The platform is fixed on the tower 1, and is provided with an air compressor 41, a cooler 42, a turbine 43 and a first generator 44. The air compressor 41 is connected to an air intake pipe 22, the air intake pipe 22 is connected to the cooler 42, the turbine 43 is transmission-connected to the first generator 44, and the turbine 43 is connected to an air outlet pipe 23.

[0045] The air storage chamber 21 is arranged in the steel foundation 2, the air inlet pipe 22 is connected to the bottom of the air storage chamber 21, and the air outlet pipe 23 is connected to the top of the air storage chamber 21. Valves are provided on the air inlet pipe 22 and the air outlet pipe 23.

[0046] The auxiliary power generation mechanism is arranged on the platform 4 , and can utilize wind and waves to perform auxiliary power generation to drive the air compressor 41 and the cooler 42 .

[0047] When the wind at sea is strong, the wind turbine on the tower body 3 is driven to generate electricity, and the auxiliary power generation mechanism can also generate electricity. The generated electricity is used to drive the air compressor 41 and the cooler 42. The air compressor 41 compresses the air, and then uses the cooler 42 to cool it down. It is transported to the air storage chamber 21 of the steel foundation 2 through the air inlet pipe 22 for storage. When the wind at sea is weak, the valve on the air outlet pipe 23 is opened, and the compressed air enters the turbine 43 through the air outlet pipe 23, driving the turbine 43 to rotate, so that the first generator 44 generates electricity and maintains the output power of the wind power system. In addition, the compressed air can be released in time according to the load demand of the power grid to increase the output power of the wind power system and ensure the stable operation of the power grid.

[0048] In this embodiment, the air inlet pipe 22 is arranged around the outside of the tower 1, and then extends to the bottom along the side wall of the steel foundation 2. The air outlet pipe 23 extends upward inside the tower 1 to pass through the platform 4 and is connected to the turbine 43. Several electric heating pipes 11 are provided inside the tower 1, and electric heating wires are provided inside the electric heating pipes 11.

[0049] The air inlet pipe 22 is wound downwardly around the outside of the tower 1. The seawater around the tower 1 can play an auxiliary cooling role, thereby improving the safety and stability of compressed air storage. When the compressed air is released, the electric heating wire in the electric heating pipe 11 is started to heat the tower 1, so that the compressed air in the air outlet pipe 23 returns to a high temperature and high pressure state, thereby improving the propulsion efficiency of the turbine 43.

[0050] Example 2:

[0051] like Figure 2 、 3 As shown in FIG5 , the auxiliary power generation mechanism includes several power generation structures, and the several power generation structures are arranged on the side of the platform 4 along the circumferential direction. The power generation structure includes a fixed block 5, a first rotating shaft 6, a second rotating shaft 7, a first disc 62,

[0052] The fixing block 5 is horizontally fixed on the side of the platform 4 through a support frame 51 , and an annular groove 52 is provided on the side of the fixing block 5 .

[0053] The first rotating shaft 6 is vertically rotatably disposed on the upper side of the fixed block 5 , and a plurality of first rotating blades 61 are circumferentially disposed on the first rotating shaft 6 .

[0054] The second rotating shaft 7 is vertically rotatably disposed on the lower side of the fixed block 5 , and a plurality of second rotating blades 71 are circumferentially disposed on the second rotating shaft 7 .

[0055] The first disc 62 is coaxially fixed on the first rotating shaft 6 . A plurality of first connecting rods 631 are circumferentially provided on the outer side of the first disc 62 . The first ring 63 is coaxially arranged on the outer side of the first disc 62 via the plurality of first connecting rods 631 .

[0056] The second disc 72 is coaxially fixed on the second rotating shaft 7 . A plurality of second connecting rods 731 are circumferentially provided on the outer side of the second disc 72 . The second ring 73 is coaxially arranged on the outer side of the second disc 72 via the plurality of second connecting rods 731 .

[0057] Several second generators 8 are circumferentially arranged in the annular groove 52. A linkage structure is provided on the input shaft of the second generator 8. When the first disc 62 and the second disc 72 rotate, the linkage structure can drive the input shaft of the second generator 8 to always rotate clockwise.

[0058] When the sea waves are strong, the wind drives the first rotor blade 61 on the first rotating shaft 6 to rotate, and the waves drive the second rotor blade 71 on the second rotating shaft 7 to rotate in the same direction, so that the first disc 62 and the second disc 72 rotate in the same direction, and the input shaft of the second generator 8 is driven to rotate clockwise through the linkage structure, and the second generator 8 generates electricity. The electric energy generated by the second generator 8 is provided to the air compressor 41 and the cooler 42, and the external air is compressed and cooled and stored in the air storage chamber 21. When the sea waves are small, the compressed air in the air storage chamber 21 is released, driving the turbine 43 to rotate, so that the first generator 44 generates electricity, thereby increasing the power generation of the wind power system at this time.

[0059] In this embodiment, the linkage structure includes a rotating disk 81 , a plurality of rotating rods 83 and a plurality of limiting rods 811 .

[0060] The rotating disk 81 is fixed on the input shaft of the second generator 8 , and an annular groove 82 is coaxially formed on the outer side of the rotating disk 81 .

[0061] Several rotating rods 83 are circumferentially arranged in the annular concave shoulder 82, and the inner ends of the rotating rods 83 are hinged to the inner side of the annular concave shoulder 82 through hinge shafts 831. The inner ends of the rotating rods 83 are provided with bevel cuts 833, and a compression spring 832 is fixedly connected between the bevel cuts 833 and the side walls of the annular concave shoulder 82. The outer ends of the rotating rods 83 extend obliquely in the counterclockwise direction.

[0062] The plurality of lower rods 811 correspond to the plurality of rotating rods 83 one by one, and the limiting rods 811 are fixed in the annular concave shoulders 82 in front of the corresponding rotating rods 83 .

[0063] When the first disc 62 and the second disc 72 rotate clockwise, the first connecting rod 631 on the first disc 62 pushes the rotating rod 83 and the rotating disc 81 to rotate clockwise, so that the second generator 8 generates electricity. At this time, the clockwise rotation of the second connecting rod 731 on the second disc 72 does not affect the rotation of the rotating rod 83. When the first disc 62 and the second disc 72 rotate counterclockwise, the second connecting rod 731 on the second disc 72 pushes the rotating rod 83 and the rotating disc 81 to rotate clockwise, so that the second generator 8 generates electricity. At this time, the counterclockwise rotation of the first connecting rod 631 on the first disc 62 does not affect the rotation of the rotating rod 83. Under the action of wind and waves in any direction, the second generator 8 can generate electricity, converting wind energy and wave energy into electrical energy, thereby improving power generation efficiency.

[0064] The above-mentioned working method of offshore wind power foundation includes the following steps:

[0065] S1. When the wind and waves are strong, the wind drives the wind turbine on the tower body 3 to generate electricity, and at the same time drives the first rotor blades 61 on the first rotating shaft 6 to rotate. The waves drive the second rotor blades 71 on the second rotating shaft 7 to rotate in the same direction, and the rotating rod 83 drives the rotating disk 81 to rotate clockwise, so that the second generator 8 generates electricity;

[0066] S2. The electric energy generated by the second generator 8 drives the air compressor 41 and the cooler 42. The air compressor 41 draws in air from the outside, and the cooler 42 cools the compressed air and stores it in the air storage chamber 21 of the steel foundation 2 through the air intake pipe 22.

[0067] S3. When the wind and waves are small, the output power of the wind turbine on the tower body 3 decreases. At this time, the valve on the air outlet pipe 23 is opened to release the compressed air in the air storage chamber 21, which drives the turbine 43 to rotate and drive the first generator 44 to generate electricity, so that the wind turbine maintains a stable output power;

[0068] S4. The first generator 44 starts the electric heating tube 11 in the tower 1 to heat the interior of the tower 1, so that the gas discharged from the outlet pipe 23 generates high temperature and high pressure, thereby improving the driving efficiency of the turbine 43.

[0069] When the wind and waves are strong, the auxiliary power generation mechanism is used to convert part of the wind energy and wave energy into mechanical energy, which is provided to the air compressor 41 and the cooler 42 to store the compressed air energy. When the wind and waves are weak, the compressed air is released and heated. The high-temperature and high-pressure air is used to drive the turbine 43 to rotate, so that the first generator 44 can generate electricity, increase the power generation capacity, and meet the stable operation of the power grid and the electricity demand under different loads.
