TECHNICAL FIELD

[0001] The present application relates to the technical field of power generation equipment accessories, in particular to a sea floating wind power generation device and a method thereof. BACKGROUND

[0002] Wind power generation refers to converting the kinetic energy of wind into electric energy. Wind energy is a clean and renewable energy source that has been used by people for a long time, mainly through windmills to pump water, grind flour, etc. People are interested in how to use wind to generate electricity. Wind power generation is very environmentally friendly, and the amount of wind energy is huge, so it is increasingly valued by countries around the world. With the development of the times and the progress of waterproof technology, offshore strong wind can be used for wind power generation, which has entered the field of vision of people. Offshore wind power can replace fossil fuel power generation on a large scale. A single 15MW unit can generate about 54GWh of electricity per year, equivalent to reducing 18,000 tons of coal per year, helping to achieve the carbon neutralization goal. Current offshore wind power technology mainly uses fixed foundation wind turbines or floating units to capture wind energy and convert it into electricity.

[0003] The existing floating unit uses a semi-submersible platform, a tension leg platform, etc. to realize deep sea deployment, and after deployment, it is welded through a jacket foundation and installed at a fixed point by cooperating with the unit hoisting. It is found in the use of the existing floating unit that the annual corrosion rate of steel components is 0.1mm in the high salt mist environment of the sea, and the service life of the traditional epoxy coating is only 15-20 years, resulting in maintenance costs accounting for more than 18% of the total cost.

[0124] In the present application, step S2 is specifically:

[0125] Step S2.1, under the action of wind blowing, the wind-driven unit is wind-driven:

[0126] Each fan blade 306 is driven by wind to rotate;

[0127] When the fan blade 306 rotates, the driven shaft 303 is driven to rotate;

[0131] The lateral rotation force transmission is changed to vertical transmission by driving the universal shaft 308 to rotate through the rotation of the driving shaft 302;

[0132] Step S2.2.2, when the driving gear 403 rotates, the lead screw 406 connected with the driving gear 403 and the driven gear 404 is driven to rotate due to the meshing relationship between the driving gear 403 and the driven gear 404;

[0133] Step S2.2.3, when the lead screw 406 rotates, the driving rack 408 is driven to vertically ascend and descend; wherein the lead screw 406 is a bidirectional lead screw, so that the driving rack 408 reciprocally slides after sliding to the limit position;

[0134] Step S2.2.4, by driving the rack 408 in the vertical direction, the lifting movement drives the rolling gear 504 connected with the generator 503 to reciprocating rotation, thereby driving the generator 503 to generate electricity; at the same time, when the rolling gear 504 and the driving rack 408 slide up and down, it drives each generator 503 and the fixed plate 502 connected with it to slide vertically on the guide rail 505 along with the adjusting plate 506, compensates the rolling number of the rolling gear 504, compensates the position of the driving rack 408, prolongs the driving number, and improves the driving efficiency;

[0136] Step S3.1, in the process of rotating the screw rod 406, the shaft seat 603 installed at the bottom of the immersion cylinder 402 supports the bottom end of the screw rod 406, improving the stability of the screw rod 406 rotation;

[0137] Step S3.2, in the process of rotating and sliding up and down of the rolling gear 504, in order to avoid the rolling gear 504 and the driving rack 408 from being separated and a gap being generated due to the vibration generated when the equipment works against the wind, the limiting rack 602 limits and stabilizes the other side of the rolling gear 504, and the bottom of the limiting rack 602 is rotatable around the hinge seat 605, realizing the stable limiting of the rolling gear 504;

[0138] Step S3.3, the limiting plate 601 is installed inside the immersion cylinder 402 to limit and stabilize the generator 503 when it slides up and down, improving the stability of the equipment when it slides;

[0139] Step S4, the balancing assembly keeps the stability of the equipment, specifically:

[0140] Step S4.1, the power supply box 701 supplies power to the whole equipment, the signal transmitter 702 detects the tidal change in real time, and controls the rotating speed and direction of the motor 711 according to the tidal change;

[0141] Step S4.2, the motor 711 drives the longitudinal screw rod 708 to rotate, thereby driving the sliding block 710 to slide longitudinally relative to the longitudinal screw rod 708;

[0142] Step S4.3, when the sliding block 710 slides longitudinally relative to the longitudinal screw rod 708, it drives the transverse screw rod 707 to rotate; when the transverse screw rod 707 rotates, the adjusting block 709 slides on the transverse screw rod 707;

[0143] Step S4.4, in the process of sliding of the adjusting block 709, the lateral stabilizing plate 704 is pulled by the spherical curved rod 706 to rotate relative to the balance frame 703 to perform lateral stabilization; meanwhile, in the process of sliding of the adjusting block 709, the longitudinal stabilizing plate 705 is swung to perform longitudinal stabilization because the longitudinal stabilizing plate 705 is fixed with the spherical curved rod 706;

[0144] Step S4.5, in the process of position change of the sliding block 710 and the adjusting block 709, the longitudinal screw rod 708 is changed in height under the action of gravity and the vibration force of the motor 711 because the two ends of the longitudinal screw rod 708 are fitted on the balance plate 713, the balance plate 713 is rotatable relative to the balance frame 703 and is supported by the spring 712, the balance plate 713 is rotated to change the height of the longitudinal screw rod 708, the lateral screw rod 707 is changed in height, and the lateral stabilizing plate 704 and the longitudinal stabilizing plate 705 are moved correspondingly by the adjusting block 709.

[0145] The application further provides a power generation method of the offshore floating wind power generation device.

[0146] S1: in the process of offshore power generation, the device is placed in a proper position, the device is floated on the sea by the floating rubber ring 301, the device is stabilized by the balancing device, when the sea surface is greatly fluctuated, the balancing device is started to move the lateral stabilizing plate 704 to rotate in the opposite direction of the blowing direction of the wind and the tide, the resistance is formed by the tide, the longitudinal stabilizing plate 705 is adjusted to keep the device basically stable, and the maximization of the wind force bearing area is improved.

[0147] S2: long time sequence simulation calculation is combined with the wind / wave / tidal current resource distribution, the power curve of the wind turbine / WEC / tidal turbine, and the device availability, loss and the like, CF=actual annual power generation / rated power*8760 hours, the driving device is started to rotate under the wind blowing according to the calculation formula, the generator 503 is rotated to generate power by the driving device and the transmission assembly.

[0148] S3: in the process of power generation, the stabilizing device is arranged in the working cavity 409 of the immersed cylinder 402 to laterally protect the power generation of the generator 503, avoid the power generation gear from being separated due to the shaking of the device, clamp the power generation gear, and improve the power generation efficiency.

[0149] S4: when the device needs to be repaired, the generator 503 and the like can be laterally removed by disassembling the transmission device, and the maintenance convenience of the device is improved by the modular design.

[0150] The application further provides a power generation method of the offshore floating wind power generation device.

[0151] S1: The mounting frame 1 and the floating rubber ring 301 are fixedly sleeved, so that the device is balanced on the water surface through the floating rubber ring 301, and in the process of needing the device to generate power at sea, long-time sequence simulation calculation is carried out in combination with wind / wave / tidal current resource distribution, power curve of the wind turbine / WEC / tidal turbine and device availability, loss and the like, CF = actual annual power generation amount / rated power * 8760 hours. The higher the CF is, the better the site selection of the wind turbine or the wind farm is, the higher the device utilization rate is, and the better the economic benefit is.

[0152] According to the calculation formula, the driving device is rotated under the blowing of the wind, the fan blades 306 are rotated through the blowing of the wind, the fan blades 306 are all installed on the corresponding longitudinal driven shafts 303, and the plurality of driven shafts 303 are uniformly installed along the top inclined angle second mounting seat 310 of the mounting frame 1, so that the problem that the blowing force at one end of the blowing is small is avoided, when the fan blades 306 drive the driven shafts 303 to rotate, the corresponding bevel gears 304 are driven to rotate through the engagement of the bevel gears 305 on the driven shafts 303, and thus the driving shaft 302 is driven.

[0153] The common fan type fan blade blowing is driven by a single shaft, and the rotation degree is small. The device drives the driving shaft 302 to rotate through the combined force of the plurality of driven shafts 303, so that the driving shaft 302 can rotate quickly, the rotation speed of the device is improved, and thus the power generation efficiency of the device is improved. When the bevel gears 304 and the bevel gears 305 mesh and rotate, the bidirectional sleeve 307 is sleeved on the driving shaft 302 and the driven shaft 303, so that the driving shaft 302 and the driven shaft 303 rotate in the bidirectional sleeve 307, and the stability of the rotation of the device is improved.

[0154] S2: The universal shaft 308 is rotatably installed on the positioning ring 309, the universal shaft 308 is driven to rotate through the rotation of the driving shaft 302, the lateral rotation force transmission is changed into vertical transmission, the immersion type cylinder body 402 and the assembled cylinder cover 401 are connected, the modular assembly is carried out when disassembly is needed, and the maintenance efficiency of the device is improved. The driving gear 403 connected with the universal shaft 308 can be driven to rotate, the lead screw 406 connected with the driven gear 404 is driven to rotate through the meshing relationship between the driving gear 403 and the driven gear 404, the lead screw 406 is selected as a bidirectional lead screw, the driving rack 408 can reciprocatingly slide after sliding to the limit position, and in this process, the rotation of the lead screw 406 is limited and stabilized through the positioning plate 405.

[0155] S3: The rolling gear 504 connected with the generator 503 is driven to reciprocatingly rotate through the up-down sliding of the driving rack 408, so that power generation is carried out.

[0156] When the driving of the rolling gear 504 and the driving rack 408 slides up and down, the generator 503 and the fixed plate 502 connected therewith can be driven to slide with the adjusting plate 506 on the guide rail 505, the rolling number of the rolling gear 504 is compensated, the driving position of the driving rack 408 is compensated, the driving number is prolonged, and the driving efficiency is improved. The maintenance convenience of the equipment is improved by adding the lateral baffle 501, and in the process, the immersion cylinder 402 enters the water, and the bottom gap formed by the arc sleeve 8 is balanced in water, so that the equipment is prevented from overturning.

[0157] Specifically, in the gear transmission, there is a small gap between the gear and the rack and between the gears. When the driving direction changes, the rotation of the motor needs to overcome the gap first, and then the load can be driven, so that the actual position deviates from the command position, which is fatal to high-precision positioning applications. Prolonging the driving number, the driving position of the driving rack is compensated by a set of independent sensing and driving system. When the system detects that the main driving displacement is insufficient due to backlash, the adjusting plate will slide to fine-tune the position of the entire generator and driving unit, so that the gear and the rack are re-tightly engaged at the correct position, thereby completely eliminating the error caused by the reverse gap and improving the driving efficiency.

[0158] As a preferred embodiment of the above embodiment: the offshore floating wind power generation device and method thereof, the stabilizing device is specifically used for:

[0159] S1: In the process of rotating the screw rod 406, the bottom end of the screw rod 406 is fixed by the bottom mounting shaft seat 603 of the immersion cylinder 402, so that the stability of the rotation of the screw rod 406 is improved;

[0160] S2: In the process of rotating the rolling gear 504, in order to avoid the gear and the rack from being separated and the gap caused by the vibration of the equipment working against the wind, the other side of the rolling gear 504 is limited and stabilized by adding the limiting rack 602, the limiting rack 602 can be fixed and rotationally connected by a bolt, and can be modularized during disassembly and assembly;

[0161] S3: The limiting plate 601 is installed at the bottom end of the immersion cylinder 402 to limit and stabilize the sliding of the generator 503, and the stability of the equipment during sliding is improved.

[0162] As a preferred embodiment of the above embodiment: the offshore floating wind power generation device and method thereof, the balancing assembly is specifically used for:

[0163] S1: Connect the end of the balance frame 703 and the bottom of the floating rubber ring 301, immerse the transverse stabilizing plate 704 and the longitudinal stabilizing plate 705 into the water, and balance and stabilize according to the basic formula of balancing the tide height, which is h = (3 / 2) * (M / E) * (R^4 / D^3) * (cos 2 θ-1 / 3), where θ is the zenith distance.

[0164] Wherein:

[0165] θ is the zenith distance;

[0166] h is the vertical displacement or the height of the bulge: this is the result of the entire formula, indicating the amount of upward or downward movement of an object's surface due to the force acting on it;

[0167] M: applied moment: the size of the torque or moment that causes the object to deform or displace;

[0168] E: Young's modulus: this is a property of the material itself, which measures the strength of the material's resistance to elastic deformation. The greater the Young's modulus, the "harder" the material, and the smaller the deformation under the same moment;

[0169] R: the radius of the object: usually refers to the radius of a sphere or cylinder that deforms,

[0170] D: the distance to the point of force action or characteristic length;

[0171] In this formula, the zenith distance θ is the key independent variable. By changing the angle θ of the observation or force action point, we can observe and calculate how it affects the final vertical displacement.

[0172] S2: Power the entire device through the power supply box, coordinate the signal transmitter 702 to respond to the detected tidal changes in an orderly manner and send signals, start the corresponding motor 711 to drive the transverse screw 707 and the longitudinal screw 708 to rotate, and make the adjusting block 709 and the sliding block 710 slide on the transverse screw 707 and the longitudinal screw 708. During the sliding process, the spherical curved rod 706 pulls the transverse stabilizing plate 704, which can rotate on the balance frame 703 to stabilize it horizontally;

[0173] S3: Because the adjusting block 709 slides on the transverse screw 707, it drives the longitudinal stabilizing plate 705 to swing, thereby stabilizing the tide vertically;

[0174] S4: in the process of position change of the slider 710 and the adjusting block 709, the transverse screw rod 707 and the longitudinal screw rod 708 change in height, the balance plate 713 connected with the longitudinal screw rod 708 rotates, the transverse screw rod 707 and the longitudinal screw rod 708 change in height are connected and stabilized, and in the process, the spring 712 is reset.

9. A method for generating electricity using a floating offshore wind power generation device according to claim 8, characterized in that, Step S2 is as follows: Step S2.1: Under the action of wind, the wind-driven unit performs wind-driven operation: The fan blades (306) are rotated by the wind. When the fan blade (306) rotates, it drives the driven shaft (303) to rotate; When the driven shaft (303) rotates, the drive shaft (302) is driven to rotate through the meshing transmission action of the bevel gear (305) and the helical gear (304); In step S2.2, the wind-driven unit drives the generator (503) to rotate and generate electricity through the transmission assembly and transmission unit: In step S2.2.1, when the drive shaft (302) rotates, it drives the universal joint (308) to rotate; when the universal joint (308) rotates, it drives the drive gear (403) to rotate. The rotation of the drive shaft (302) drives the universal joint (308) to rotate, so that the lateral rotational power transmission becomes vertical transmission; In step S2.2.2, when the drive gear (403) rotates, due to the meshing relationship between the drive gear (403) and the driven gear (404), the lead screw (406) connected to the driven gear (404) is driven to rotate. In step S2.2.3, when the lead screw (406) rotates, it drives the drive rack (408) to move vertically up and down; wherein, the lead screw (406) is a bidirectional lead screw, so that the drive rack (408) slides back and forth after sliding to the limit position; In step S2.2.4, the vertical lifting and lowering movement of the drive rack (408) drives the rolling gear (504) connected to the generator (503) to reciprocate, thereby driving the generator (503) to generate electricity; at the same time, when the rolling gear (504) and the drive rack (408) slide up and down, each generator (503) and the fixed plate (502) connected to it slide vertically on the guide rail (505) along with the adjusting plate (506), compensating for the number of rolling revolutions of the rolling gear (504), compensating for the position of the drive rack (408), extending the number of drive revolutions, and improving the drive efficiency; Step S3, the stabilizing device provides lateral protection for the generator (503), specifically as follows: Step S3.1: During the rotation of the lead screw (406), the bottom end of the lead screw (406) is supported by the bearing seat (603) installed at the bottom of the immersion cylinder (402), thereby improving the stability of the rotation of the lead screw (406). In step S3.2, during the rotation and sliding of the rolling gear (504), in order to prevent the rolling gear (504) from disengaging from the drive rack (408) and creating a gap due to vibration generated when the equipment is working in the wind, the limiting rack (602) limits and stabilizes the other side of the rolling gear (504). Furthermore, the bottom of the limiting rack (602) can rotate around the hinge seat (605) to achieve stable limiting of the rolling gear (504). Step S3.3: Install a limiting plate (601) inside the immersion cylinder (402) to limit and stabilize the generator (503) when it slides up and down, thereby improving the stability of the equipment when it slides. Step S4, the balancing component maintains the stability of the device as follows: Step S4.1: Power the entire equipment through the power supply box (701), and the signal transmitter (702) detects the tidal changes in real time and controls the speed and direction of the motor (711) according to the tidal changes. In step S4.2, the motor (711) drives the longitudinal screw (708) to rotate, thereby causing the slider (710) to slide longitudinally relative to the longitudinal screw (708); Step S4.3: When the slider (710) slides longitudinally relative to the longitudinal screw (708), it drives the transverse screw (707) to rotate; when the transverse screw (707) rotates, the adjusting block (709) slides on the transverse screw (707). In step S4.4, during the sliding of the adjusting block (709), the lateral stabilizing plate (704) is pulled by the spherical crank (706), causing the lateral stabilizing plate (704) to rotate relative to the balance frame (703) to achieve lateral stabilization; at the same time, during the sliding of the adjusting block (709), since the longitudinal stabilizing plate (705) is fixed to the spherical crank (706), the longitudinal stabilizing plate (705) is driven to swing, thereby achieving longitudinal stabilization of the tide; In step S4.5, during the position change of the slider (710) and the adjusting block (709), since the two ends of the longitudinal screw (708) are mounted on the balance plate (713), and the balance plate (713) is rotatable relative to the balance frame (703) and supported by the spring (712), the balance plate (713) rotates under the action of gravity and the vibration force of the motor (711), causing the longitudinal screw (708) to fluctuate in height, thereby causing the transverse screw (707) to fluctuate in height accordingly, and further causing the transverse stabilizing plate (704) and the longitudinal stabilizing plate (705) to perform corresponding actions through the adjusting block (709).
