Background
Clean energy is the mainstream development direction in the world today. Wind power generation is one of clean energy sources, and is widely applied to the environment with more wind resources at present. Wind power plants are structurally divided into horizontal and vertical axes, and at present horizontal axis wind power generation has been developed to 15MW, with tower heights exceeding 200 meters and impeller diameters exceeding 180 meters, which presents a huge challenge to the design, installation, maintenance and reliability of large wind power generation. On land, the transportation is difficult due to the overlong blades, so that the land is difficult
The power increase of the upper fan is limited; for an offshore wind turbine, under extreme weather conditions such as typhoon, irreversible damage can be caused to a high-rise wind tower and blades.
The vertical axis fan is divided into a resistance type and a lift type, the resistance type has low utilization rate of wind energy, and cannot be used for large-scale wind power generation. One reason that the conventional vertical axis high-power fan is not as popular as a horizontal axis fan is that the larger the power is, the larger the blade is, the larger the weight of the blade makes the cantilever beam structure difficult to enlarge, and designers can support the pressure stopping wheel and the pressure stopping wheel sliding plate at the bottom of the blade to possibly enlarge the blade. For example, chinese patent publication No. CN109763941A discloses a vertical axis wind power generation apparatus and a power generation method. The vertical axis wind power generation equipment comprises a base, an annular track, at least two rail cars, a generator and a vertical main shaft, wherein the annular track is fixedly arranged on the base, a rail car frame is arranged on the annular track, at least one lifting force blade is arranged on each rail car, each rail car is fixedly connected with the vertical main shaft through at least one cross beam, the lifting force blades generate lifting force by wind, the rail cars are pushed to move annularly along the annular track, and the vertical main shaft is driven to rotate through the cross beams to drive the generator to generate electric energy. If a canvas exhibition wing vertical axis aerogenerator who announces No. CN210087547U again includes the generator, be equipped with the support on the transmission shaft of generator, sliding connection has the one end of slider on the support, the other end sliding connection of slider is on the slide, the slide sets up on the stationary plane, the tip of support is equipped with the blade system, the blade system includes the main shaft, the main shaft rotates through rotating the bolt and connects the rotor plate, be equipped with the canvas flabellum on the rotor plate, be equipped with the one end of stretching rope on the canvas flabellum, the other end of stretching rope is connected on the slider, through when the blade system rotates along with wind-force, slide and slider mutually support and can drive the angle that the stretching rope changed the blade system. The blade of above-mentioned two kinds of aerogenerator all need the bearing of ending pinch roller slide or slide to support the weight of large-scale blade, because ending pinch roller slide and ending pinch roller direct contact have frictional force between the two, in addition blade weight is great, and this partial frictional force is great, so, has not only offset some wind energy, has reduced the generating efficiency, has increased the degree of difficulty that aerogenerator started moreover.
In addition, in order to reduce the friction force of the blades, a structure adopting suspension support is also provided, for example, chinese patent publication No. CN210317601U, a vertical axis wind turbine with a magnetic suspension bearing structure includes a vertical axis, a wind turbine and a wind wheel arranged on the vertical axis and driving the wind turbine, the wind wheel includes a rotating cage rotatably mounted on the vertical axis, blades arranged outside the rotating cage and a connecting rod connecting the blades and the rotating cage, a magnetic suspension pressure-stopping wheel sliding plate is fixedly arranged below the wind wheel, a sliding block matched with the magnetic track is arranged at the bottom of the wind wheel, and a buoyancy generating unit is arranged between the magnetic suspension pressure-stopping wheel sliding plate and the sliding block. By adopting the technical scheme, the sliding block is arranged at the bottom of the wind wheel and is arranged in the magnetic suspension pressure stopping wheel sliding plate, the sliding block moves in the magnetic suspension pressure stopping wheel sliding plate along with the wind wheel in the rotating process of the wind wheel, and the buoyancy generating unit exerts upward force on the sliding block to play a role in supporting the wind wheel. Although the magnetic suspension structure can also reduce the friction force of the blade, the magnetic suspension structure is expensive in manufacturing cost and requires unscheduled maintenance, so that the power generation cost is increased.

3. A vertical axis sail type wind turbine as claimed in claim 1, wherein: and a steel cable is arranged between the mast and the ship body or between the mast and the cantilever.
4. A vertical axis sail type wind turbine as claimed in claim 1, wherein: the main shaft is sleeved with a hub, and the cantilever is connected with the main shaft through the hub.
5. A vertical axis sail type wind turbine as claimed in claim 1, wherein: the wind driven generator further comprises an installation platform, and the pressure stopping wheel sliding plate is installed on the installation platform or is independently arranged around the installation platform.
6. A vertical axis sail type wind turbine as claimed in claim 5, wherein: the mounting platform is a machine room and comprises a machine room wall body and a machine room roof, the pressure stopping wheel sliding plate is arranged on the machine room roof, and the generator set is arranged in the machine room wall body.
7. A vertical axis sail type wind turbine as claimed in claim 6, wherein: the main shaft is arranged in the machine room, the upper end of the main shaft penetrates out of the roof of the machine room, and at least two bearings sleeved on the main shaft are arranged in the machine room.
8. A vertical axis sail type wind turbine as claimed in claim 5, wherein: the mounting platform is arranged on the roof of a building.
9. A vertical axis sail type wind turbine as claimed in claim 1, wherein: the generator set comprises a generator, a speed changer and a transmission mechanism, wherein a gear disc is sleeved on the main shaft, the gear disc drives the speed changer through gear engagement, and the speed changer drives the generator through the transmission mechanism.
10. A vertical axis sail type wind turbine as claimed in claim 1, wherein: the pressure stopping wheel is connected with the lifting mechanism.
