Abstract
Description
Technical Field
[0001] The invention relates to the field of wind power generation devices, and in particular to a water-floating track steel wheel wind power generator and an operating method thereof. Background Art
[0002] At present, wind power generation equipment is generally divided into two types, one is horizontal axis power generation equipment, the other is vertical axis power generation equipment. The technology of horizontal axis power generation equipment developed earlier and is relatively mature. Most high-power power stations choose this type of equipment, but the installation position of important equipment is too high, which is inconvenient for maintenance; the center of gravity is too high, which affects the stability of the equipment and the ability to resist wind disasters. The yaw system of the equipment and the strength requirements of the tower increase the cost of the equipment; therefore, vertical axis wind power generation equipment has become the focus of people's attention and research. The existing vertical axis wind power generation technology has low wind utilization rate, difficulty in starting, easy stalling, and low output power.
[0003] For example, the invention with publication number CN111622902A discloses an overall construction method of a novel vertical axis wind power generation equipment: it is composed of the following main parts: a hemispherical machine room, a main shaft main bearing mounting hole is reserved on the top, a mounting platform is arranged in the middle layer, a main shaft secondary bearing mounting hole is reserved in the center of the platform, a generator mounting platform is arranged on the ground, power generation equipment: a low-speed vertical axis generator is installed on the ground platform in the machine room, the generator input shaft and the lower end of the main shaft are connected by a coupling, a multifunctional main shaft: the main shaft is vertically penetrated and installed in the bearing mounting hole on the top of the machine room and the secondary bearing mounting hole on the middle platform, and is supported by bearings, a multifunctional column: it is vertically installed on the upper end of the main shaft and connected by a flange, and a horizontally penetrating fan shaft hole is reserved on the upper section of the column, a fan shaft: it is evenly and horizontally penetrated and installed on the column, the fan shaft and the two sides of the column are respectively supported by two bearings, and two flat movable fan blades are respectively fixed at the two ends of the same fan blade shaft, with an end-view angle of 90 degrees, and all fan blades are installed in the same way.
[0004] However, the main shaft of the above-mentioned existing vertical axis wind power generation equipment is rotatably connected through a bearing and equipped with a support structure. For large-sized wind turbines, in order to ensure the stability of the main shaft support and rotation, the structure will be more complicated and the cost will be higher, which is not conducive to the promotion of wind turbines. The power generation component of the wind turbine is connected to the main shaft, the transmission structure is relatively complicated, and the wind catching ability of the vertically arranged blades is relatively weak. Summary of the invention
[0005] The purpose of the present invention is to overcome the defects of the above-mentioned prior art in that the main shaft support structure of the wind turbine and the transmission structure between the main shaft and the generator are complex, and to provide a water-floating rail steel wheel wind turbine generator and an operating method with stable operation and high power generation efficiency.
[0006] The purpose of the present invention can be achieved by the following technical solutions:
[0007] A water-floating track steel wheel wind turbine generator, comprising a wind turbine base, a wind turbine main shaft and wind turbine blades, the generator also comprising a generator set, an auxiliary generator set, a transmission track and a motor support platform;
[0008] A fan water pool is provided in the fan base, and the fan main shaft can be rotatably mounted on the fan base and suspended in the fan water pool; the motor support platform is mounted on the periphery of the fan base and is located directly below the fan blades, the generator set and the auxiliary generator set are both fixed on the motor support platform, and the transmission track is fixed at the lower end of the fan blades, and the transmission track respectively transmits and connects the generator set and the auxiliary generator set.

[0017] Preferably, there are multiple generator sets and auxiliary generator sets, and the generator sets and auxiliary generator sets are cross-distributed on the motor support platform.
[0018] This solution also provides an operation method of a water-floating rail steel wheel wind turbine generator, wherein the auxiliary generator set is an electric generator integrated machine including a braking structure, and the method comprises the following steps:
[0019] Obtain the ambient wind speed and the rotation speed of the fan main shaft, and adjust the auxiliary generator set to make the fan main shaft rotate at a constant speed according to the preset speed;
[0020] The specific adjustment process of the auxiliary generator set includes:
[0021] When the ambient wind speed is less than the preset value and the fan main shaft speed is on a downward trend, the auxiliary generator set acts as a motor to provide driving force for the transmission track, so that the fan main shaft rotates at the preset speed;

Using the fan pool to suspend the fan main shaft can effectively reduce the friction of the fan main shaft, which can help improve the power generation efficiency and effectively extend the service life of the fan main shaft.
[0027] (2) This scheme takes into account that the fan blades will produce certain fluctuations in the vertical direction during their rotation; by setting spring shock absorbers at the lower ends of the generator set and the auxiliary generator set, reliable contact between the rails and the steel wheels of the generator set and the auxiliary generator set is ensured, and the generator set is protected to ensure the reliability and stability of the transmission structure.
[0028] (3) This solution fixes the two ends of the blade on the blade top cover and the bottom fixing frame respectively, and distributes the blades along the circumference of the fan top cover. The blades are tilted, with the air inlet on one side facing outward and the air outlet on the other side facing inward. This can effectively increase the wind sweeping area of the fan blades, have a stronger wind capture ability, can drive a wind turbine with higher power, and reduce the power generation cost.

[0041] Working principle: The fan main shaft 2 is rotatably installed in the fan base 1, and the fan water pool 101 in the grading base 1 is used to suspend the fan main shaft 2 to complete the fixation and support of the fan main shaft 2; during the rotation of the fan blades 3, the transmission track 7 installed at the lower end drives the generator set 4 and the auxiliary generator set 5 on the periphery of the fan base 1 to rotate to complete power generation.
[0042] The transmission track 7 set at the lower end of the fan blade 3 can directly drive the generator set 4 and the auxiliary generator set 5 set on the periphery of the fan base 1 to rotate, thereby completing power generation, simplifying the complex transmission structure connected to the fan main shaft, reducing costs, and the generator set set on the periphery has a larger driving path, which can effectively improve the power generation efficiency. The fan main shaft 2 is suspended by the fan pool 101, which can effectively reduce the friction of the fan main shaft, and can effectively extend the service life of the fan main shaft 2 while assisting in improving the power generation efficiency.
[0043] In a preferred embodiment, steel wheels are respectively provided on the rotating shafts of the generator set 4 and the auxiliary generator set 5, and the steel wheels cooperate with the transmission track; the auxiliary generator set is an electric generator integrated machine, including an electronic control module and a braking structure, the electronic control module is used to switch the generator and motor status of the auxiliary generator set, and the braking module is used to assist in decelerating the transmission track.
[0044] Furthermore, a plurality of spring shock absorbers are provided on the motor support platform 6, and the generator set 4 and the auxiliary generator set 5 are respectively mounted on each spring shock absorber.
[0045] Taking into account that the fan blades will produce certain fluctuations in the vertical direction during their rotation, spring shock absorbers are arranged at the lower ends of the generator set 4 and the auxiliary generator set 5 to ensure reliable contact between the rails and the steel wheels of the generator set 4 and the auxiliary generator set 5, and to protect the motor set, thereby ensuring the reliability and stability of the transmission structure.
[0046] In a preferred embodiment, the fan blade 3 includes a blade top cover 31, a blade 32 and a bottom fixing frame 33;
[0047] The blade top cover 31 is fixed to the upper end of the fan main shaft 2 , the bottom end fixing frame 33 is fixed to the fan main shaft 2 , one end of the blade 32 is fixed to the blade top cover 31 , and the other end is fixed to the bottom end fixing frame 33 .

[0049] By fixing the two ends of the blade 32 on the blade top cover 31 and the bottom fixing frame 33 respectively, and distributing the blade 32 along a circle of the fan top cover 31, the blade 32 is tilted, with the air inlet on one side facing outward and the air outlet on the other side facing inward, the wind sweeping area of the fan blade can be effectively increased, with a stronger wind catching ability, capable of driving a wind turbine with a higher power, and reducing the cost of power generation.
[0050] Furthermore, the fan blade 3 also includes a steel wire rope inclined cable 34 , one end of which is fixed to the fan main shaft 2 , and the other end is connected to the bottom fixing frame 33 .
[0051] The bottom fixing frame 33 includes a plurality of coaxially arranged circular ring structures 35 , and support rods 36 are arranged between adjacent circular ring structures 35 , and the support rods 36 are radially distributed.
[0052] A coaxially distributed circular ring structure is adopted on the bottom fixing frame 33, and each layer of the circular ring structure is fixed to the fan main shaft 2 by a plurality of steel wire rope inclined cables 34, and a support rod is arranged between two adjacent circular ring structures. The support rods are radially distributed, and the number of support frames between the circular ring structures increases successively from the inside to the outside in the radial direction, which can ensure the stability of the structure while reducing unnecessary waste, thereby improving the supporting capacity of the bottom fixing frame 33 and the stability of the fan blades.
[0053] Specifically, the fan main shaft 2 is a stepped shaft, a first bearing is installed at the upper end of the fan main shaft 2, a bearing seat is provided at the upper end of the fan base 1, and the first bearing is installed in the bearing seat.
[0054] A fixed bearing and square steel are provided at the lower end of the fan main shaft 2 . The outer ring of the fixed bearing is fixed to the bottom end of the fan main shaft 2 . One end of the square steel is fixed in the inner ring of the fixed bearing, and the other end is fixed to the bottom of the fan pool 101 .
[0055] There are multiple generator sets 4 and auxiliary generator sets 5 , and each generator set 4 and auxiliary generator set 5 is cross-distributed on the motor support platform 6 .
[0056] An auxiliary generator set 5 is distributed between the two generator sets 4. The auxiliary generator set 5 is an integrated motor and generator, which can drive the transmission track and brake the transmission track at the same time, thereby ensuring the rotation speed of the wind turbine blades and the power generation efficiency of the generator set 4 and maintaining the stability of the wind turbine.
[0057] This embodiment also provides an operation method of a water-floating rail steel wheel wind turbine, characterized in that the auxiliary generator set 5 is an integrated electric generator, including a braking structure, and the method comprises the following steps:
[0058] Obtain the ambient wind speed and the rotation speed of the fan main shaft, and adjust the auxiliary generator set 5 to make the fan main shaft 2 rotate at a constant speed according to the preset speed;
[0059] The specific adjustment process of the auxiliary generator set 5 includes:
[0060] When the ambient wind speed is less than the preset value and the fan main shaft speed is on a downward trend, the auxiliary generator set 5 acts as a motor to provide driving force for the transmission track, so that the fan main shaft 2 rotates at a preset speed;
[0061] When the ambient wind speed is greater than the preset value and the fan main shaft speed is on the rise, the auxiliary generator set 5 acts as a generator and cooperates with the brake structure to provide braking force for the transmission track, so that the fan main shaft 2 rotates at the preset speed;
[0062] When the ambient wind speed exceeds the safety standard, the water level in the fan pool 101 drops, causing the fan main shaft 2 to be locked; when the wind speed reaches the safety standard, the water level in the fan pool 101 is increased, causing the fan main shaft 2 to operate.
[0063] This embodiment also provides a more specific implementation method. The preparation method of the above wind turbine generator includes the following steps: first, the outer diameter of the wind turbine base 1 is 45 meters, the height is 30 meters, the inner diameter of the wind turbine pool 101 is 40 meters, and the diameter of the circular drum outside the wind turbine main shaft 2 is 30 meters and the height is 25 meters;
[0064] The central axis formed by the square steel is set at the center of the fan pool 101, connected to the inner ring of the fixed bearing, inserted into the fan pool 101, and fixed at the center of the fan pool 101, perpendicular to the bottom of the fan main shaft 2 in the fan base 1, and located at the center of the wind turbine;
[0065] The outer steel frame of the bottom fixing frame 33 is pulled upward by a steel wire rope inclined cable 34 and fixed on the fan main shaft 2. The fan base 1 is installed 5 meters above the water surface or the ground; the center radius of the motor support platform 6 and the fan base 1 is 259 meters, and the diameter is 518 meters; the diameter of the transmission track 7 is 518 meters; the steel wheels of the generator set 4 and the auxiliary generator set 5 are connected and driven upward with the circular steel rail (13) at the bottom of the fan blade;
[0066] The fan top cover 31 is completely sealed with steel plates, which are watertight and airtight; the blades 32 are made of 304 stainless steel rolled plates, the height of the blades 32 is 135 meters, the thickness of the rolled plates is greater than 6 mm, and the length of the rolled plates is 135 meters plus the curvature is 1.6 times. The actual length is 216 meters, which can be cut in one piece, and the width is 24 meters. 20 rolled plates of 122 cm need to be welded together.
[0067] The blades 32 are cut and welded at the construction site. The blade width is 24 meters, the air outlet slot is 4 meters, the air inlet slot is 4 meters, and the middle is a 16-meter flat plate. A special press is used to press out a semicircular inlet and outlet shape. After the press is pressed into shape, the pressed blades 32 are directly lifted by a crane to the top installation position, and fixed on the fan top cover 31 and the bottom fixing frame 33 with stainless steel screws.
[0068] The width of fan blade 3 is 24 meters, the bottom diameter is 518 meters, and the circumference is 1628 meters. About one-sixth of the blade is the size of the upper and lower blades stacked together. The actual width in the middle of the blade is about 20 meters, and the circumference is 1626 meters. The required blades are 80 to 82 blades that are 24 meters wide and 216 meters long.
[0069] The diameter of the transmission track 7 is 518 meters. The motor support platform 6 is divided into 48 platforms. Each rectangular platform is 4-5 meters wide and 15-16 meters long. Each motor support platform 6 is 259 meters away from the fan base. The distance between two motor support platforms 6 is 1518 meters × 3.14÷48 = 34 meters.
[0070] Each motor support bar 6 is equipped with 4 generator sets with a power of 1000 kilowatts, and 4 auxiliary generator sets, each with a power of 200 kilowatts.
[0071] There are 192 generator sets 4, including 192 auxiliary generator sets. The total power of the generator sets is 1000 kW×192=192000 kW, and the total power of the auxiliary generator sets is 200 kW×192=38400 kW. The total installed capacity of wind turbines is 230400 kW.
[0072] The rated speed of the fan is 2 revolutions per minute, the moving distance of the transmission track is 518×3.14×2=3253 meters, and 3253×60=195 kilometers per hour.
[0073] The efficiency between the rail and the steel wheel is 80% per minute, the actual moving circumference of the steel wheel is 3253×0.8=2602 meters, the generator speed is 1500 revolutions per minute, 2602÷1500=1.73 meters, and the diameter of the generator steel wheel is 1.73m. ÷3.14=0.55 meters.
[0074] The wind speed in nature is sometimes high and sometimes low. If the wind speed is low and the fan cannot reach 2 revolutions per minute, the generator of the auxiliary generator set is converted into an electric motor according to the fan speed to drive the fan to reach the speed requirement. The reason for using a 1000 kW generator is that domestic 1000 kW generators are produced by many companies, with guaranteed quality and high cost performance.
[0075] The performance and output of the water-floating rail steel wheel wind turbine generator is significantly improved compared with the existing horizontal axis generator. The cost price per kilowatt-hour of electricity generated will be much lower, and the maintenance cost can also be reduced. The auxiliary generator set imitates the principle of the rear wheel of an electric car, including the brake device and automatic electronic control to adjust according to the operation of the fan. The outer circle is the outer air inlet of the fan blade.
[0076] Four main generators are installed on one platform, and two auxiliary generators are installed on the side, and two spare generators are reserved. Total: 8 generator positions The entire generator is composed of 48 platforms. For the sake of illustration, the rectangular outer foundation is enlarged 3 times. The steel rails at the bottom of the wind blades are represented by thick lines, and the steel rails drive the generators on the platforms below to generate electricity.
[0077] When the wind is light in nature and the fan fails to reach the rated speed, the auxiliary generator is converted from a generator to an electric motor and uses the backup power to drive the rails to reach the rated speed. The fan frame structure consists of three sets of steel frames, with 12 to 24 steel frames from the central axis to the periphery, the first inclined cable, and another 24 to 48 steel frames for the second inclined cable. The fan base is set as the main setting of the fan, including the peripheral foundation setting of the pool generator buoy, etc., which will not be discussed here.
[0078] In combination with the above embodiments:
[0079] The wind swept area of the generator blades is 518 meters in diameter, the blade height is 135 meters, and the fan speed is 2 revolutions per minute;
[0080] 518x×3.14x2=3253 meters
[0081] 3253 x 60 minutes = 195,000 meters
[0082] Can drive 2.27×10 6 KW generator rotates.
[0083] To calculate how many kilowatts of generators this vertical axis wind turbine can drive, we need to use the power calculation formula of the wind turbine. Substituting each value into the formula, we get:
[0084] P=1 / 21.225×2.5×10.5×54.173×0.4=0.6125×2.1×10.5×54.173×0.4=2.27×10.9W=2.27×10 6 KW
[0085] The wind turbine can actually drive 2.27×10 6 KW, it can obviously drive the total installed capacity of wind turbines to 230400 kilowatts, and the wind turbines can run smoothly.
[0086] The preferred specific embodiments of the present invention are described in detail above. It should be understood that a person skilled in the art can make many modifications and changes based on the concept of the present invention without creative work. Therefore, any technical solution that can be obtained by a person skilled in the art through logical analysis, reasoning or limited experiments based on the concept of the present invention on the basis of the prior art should be within the scope of protection determined by the claims.
