Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation, in particular to a frame-type cluster ship-type sail vertical-axis rotating double-horizontal-axis wind power generator set. Background Art

[0002] In the field of wind turbine power generation, the common methods are either vertical axis or horizontal axis.

[0003] As far as we know, due to technical limitations, the vertical shaft type has a smaller power generation capacity than the horizontal shaft type, and all use permanent magnet direct drive generators, which are mainly used for tourism power generation, household electricity, and small-scale regional civil electricity needs. The horizontal shaft wind turbines are mostly double-fed asynchronous generators, which have large power and can be set from 1MW to 30MW. They are the main models connected to the power grid after power generation. They represent the three-blade wind turbines that stand up in many places across the country. Nowadays, since this wind turbine needs to work at a wind speed of more than 6 meters, several links in design, production, transportation and installation have reached their limits. The tower height of this model on land is nearly 150 meters (including the height of the cabin), and the length of a single blade is also over 100 meters. What's more, due to the stereotyped theoretical mode and mathematical model of its blades, after the model was introduced from abroad, it was not relaxed. No enterprise ever thought of innovative design. A blade must be formed in one go and cannot be spliced ​​in the middle of composite materials (including expensive carbon fiber materials). Otherwise, after installation and use, the blade will be broken due to comprehensive factors including gravity. Such long blades are usually set up on the mountain, so it is quite difficult to transport them even with professional transportation vehicles. There have been many cases in China where vehicles and blades rolled down the cliff together, causing heavy losses of personnel and equipment.

[0004] In addition, the three-blade generator can only work when the wind speed is above 6 meters. According to statistical data, its annual working time is about 2,500 hours, that is to say, its effective power generation time is about 100 days each year, and it is not working for the rest of the time.

[0005] One advantage of a vertical-axis wind turbine is that its rotating part requires very little wind force, and can start generating electricity with a wind speed of 2 meters (level 3 breeze). Therefore, the previous patent application for a ship-type sail vertical-axis to horizontal-axis wind turbine generator set with application number 2024203333439 is to integrate the advantages of vertical-axis and horizontal-axis power generation into one, and to eliminate the weaknesses of both as much as possible. However, the main outline of this application is still a three-blade structure, with a tower and a cabin at the top of the tower. The difference is that the tower is lower in height than the blade type, because the required wind speed is not 6 meters, but only 2 meters or more, so a high tower is also a waste of investment.

[0006] To this end, the present application has made further innovations and optimized designs to this wind turbine generator set. Utility Model Content

[0007] The utility model is to solve the shortcomings of the prior art and propose a frame-type cluster ship-type sail vertical-axis rotating double-parallel-axis wind power generator set.

[0013] Furthermore, multiple generator sets all include a generator, and the generator is fixedly mounted on the top of the rubber pad. A speed increaser gearbox is provided on one side of the generator, and the gear at the end of the input shaft of the generator is meshingly connected with the gear at the end of the output shaft of the speed increaser gearbox.

[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0034] like Figures 1 to 8 As shown, it involves a frame-type cluster ship-type sail vertical-axis rotating double-horizontal-axis wind turbine generator set, including three towers 1, one of which has a special elevator arranged inside, and each floor has a door for use by workers and maintenance personnel. The elevators arranged in the other two towers 1 are usually sightseeing elevators. Multiple grid supports are fixedly installed on the outer walls of one side of the three towers 1, and a flat grid 6 is fixedly installed on the top of the three grid supports on the same floor. Multiple grid supports all include support brackets 2, and the support brackets 2 are fixedly connected to the adjacent towers 1, and the top of the support brackets 2 is fixedly connected to a support body 9, and the support body 9 is fixedly connected to the flat grid 6. The top of the top flat grid 6 is fixedly paved with a roof panel, and the tops of the remaining multiple flat grids 6 are fixedly paved with floor slabs 18. The flat grid 6 is an isosceles triangle, and the triangle has good stability. The setting of the floor slab 18 is conducive to the walking of staff.

[0035] Except for the topmost flat grid frame 6, the tops of multiple flat grid frames 6 are fixedly installed with boxes 5, the inner bottoms of multiple boxes 5 are fixedly connected with rubber pads 10, the tops of multiple rubber pads 10 are rotatably connected with ship-type sail vertical shafts 8, and the tops of the ship-type sail vertical shafts 8 penetrate the box body 5 and are rotatably connected with adjacent flat grid frames 6, the outer surfaces of multiple ship-type sail vertical shafts 8 are fixedly sleeved with vertical shaft bevel gears 14, two generator sets are symmetrically installed inside the multiple boxes 5, and the generator sets are connected to the adjacent vertical shaft bevel gears 14, and the multiple generator sets include generators 17, and the generators 17 are fixedly installed on the tops of the rubber pads 10. A speed increaser gearbox 16 is provided on one side of the motor 17, and the input shaft end gear of the generator 17 is meshed and driven with the output shaft end gear of the speed increaser gearbox 16. The speed increaser gearbox 16 is fixedly installed on the top of the rubber pad 10. The input shaft of the speed increaser gearbox 16 is transmission-connected with the speed increaser flat shaft 11. The other end of the speed increaser flat shaft 11 is fixedly connected with a flat shaft bevel gear 13, and the flat shaft bevel gear 13 is meshed with the adjacent vertical shaft bevel gear 14. The outer surface of the speed increaser flat shaft 11 is rotatably sleeved with a flat shaft bracket 12, and the flat shaft bracket 12 is fixedly installed on the top of the rubber pad 10. The rubber pad 10 has vibration reduction and noise reduction effects.

[0036] The outer surfaces of multiple boat-type sail shafts 8 are all fixedly sleeved with rotating racks, and the multiple rotating racks all include shaft sleeves 15, and the shaft sleeves 15 are fixedly sleeved on the outer surfaces of the boat-type sail shafts 8, and the outer surfaces of the shaft sleeves 15 are fixedly connected with multiple chord brackets 4, and the outer surfaces of the multiple chord brackets 4 are all fixedly embedded with four boat-type sail bodies 7, and two short support rods 20 are commonly fixedly connected between the middle parts of two adjacent chord brackets 4, and two long support rods 19 are commonly fixedly connected between the ends of two adjacent chord brackets 4. The boat-type sail body 7 is made of Kevlar fiber cloth. Kevlar cloth is light, durable, and tensile-resistant. Since the sail made of it is a flexible material, it has strong wind-surfing ability;

[0037] This design adopts seven chord brackets 4, which is more appropriate. If the number of chord brackets 4 exceeds seven, such as nine, the sails are too dense in the drawing analysis, and the sails block each other, so that the sails after the shielding are affected by the wind and the wind; if five chord brackets are used, the sails are too sparse, and the thrust and torque generated by the sails after the wind are also adversely affected.

[0038] A supporting mechanism is installed between multiple rotating frames and the tower 1, and the multiple supporting mechanisms include three cantilever support beams 3 and multiple U-shaped guide rails 21. The cantilever support beams 3 are fixedly connected to adjacent towers 1, and the tops of the three cantilever support beams 3 are fixedly connected to wheel brackets 23. The inner walls on both sides of the three wheel brackets 23 are rotatably connected to support wheels 22. Multiple U-shaped guide rails 21 are respectively fixedly installed at the bottoms of adjacent chord brackets 4, and the U-shaped guide rails 21 match the supporting wheels 22.

[0039] Working principle: When the wind speed (the wind speed is calculated from 10 meters above the ground surface, and the height of the overhead layer in this design is 30 meters) reaches more than 2 meters per second, the rotating frame rotates and starts to work. The boat-type sail body 7 is driven by the wind to drive the chord bracket 4 and the vertical shaft sleeve 15 to rotate, and the vertical shaft sleeve 15 drives the boat-type sail vertical shaft 8 to rotate. The boat-type sail vertical shaft 8 drives the vertical shaft bevel gear 14 to rotate, and the vertical shaft bevel gear 14 drives the speed increaser horizontal shaft 11 to rotate through the horizontal shaft bevel gear 13. The speed increaser horizontal shaft 11 is increased by the speed increaser gear box 16 and then drives the generator 17 to generate electricity.

[0040] The rotating frame of the present invention is equipped with an external brake device. When the wind speed is greater than 8 meters per second, in order to prevent the rotating frame from being damaged, the rotating frame is braked to reduce the rotation speed of the rotating frame. The brake device is installed on the top plate of the box body 5, close to the boat-style sail vertical shaft 8, connected to the boat-style sail vertical shaft 8, and brakes the boat-style sail vertical shaft 8.
