Problems solved by technology

[0004] 2. Difficult to make high power
[0005] 3. Cannot change pitch
[0006] 4. At present, the swept area and the height of the wind rotor of various lift-type vertical axis wind turbines are invariable, and the adaptability to wind speed changes is narrow, and the ability to resist hurricanes is also poor.
[0007] 5. The starting performance is poor, and some vertical axis wind turbines even need to convert the generator into a motor to start the wind rotor

Embodiment 1

[0044] see Figure 3-4 As shown, a vertical axis wind turbine includes a tower body 300, a freely rotatable main shaft 108 is arranged inside the tower body 300, and a cylindrical central column is arranged outside the main shaft 108, and the central column is composed of a column 101 and a beam 102. Form a regular polyhedral frame structure, and the central column is fixedly connected with the main shaft 108;

[0045] The central cylinder is a cylindrical regular polyhedral frame body. The number of faces of the polyhedron is equal to the number of 400 paddles or an integral multiple of the number of 400 blades. The diameter of the inscribed circle does not need to be too large. The ground is assembled around the tower; the central column is connected with the main shaft 108 by several cross-arm beams 105 through the wind wheel hub 107, and several diagonal tie rods 106 are used to increase the connection strength and control the verticality of the central column.

Embodiment 2

[0062] Such as Figure 11 and 12 As shown, it is an all-electric propulsion wind energy ship. In order to obtain sufficient wind energy and make the ship have good seakeeping performance, the wind energy ship generally adopts a twin-hull or trimaran hull in order to be equipped with a large sweeping area. wind machine 501. Figure 13 Block diagram of its propulsion system. The wind turbine 501 in the figure is installed on the main hull in the middle, the main shaft drives the generator 503, the electric energy is rectified and converted by the frequency conversion mechanism, and drives the electric thruster 504 under the control of the control mechanism. The battery array stores electrical energy and is used to smooth out fluctuations in wind energy. Controls such as steering and reversing of the ship can be realized by the electric propeller 504, so the rudder and the steering gear system are canceled. The oil generator set 503 reserved on board is used for emergency whe...

Embodiment 3

[0064] Figure 14 and 15 It is a schematic diagram of a semi-electric propulsion wind energy ship, which is characterized by a wind turbine main shaft 502 driving a large gear 601, driving a group of small gears 602, each small gear 602 is speeded up by a group of gears through its own clutch 603, The respective water jet propulsion pumps 605 and generators 503 are driven. The inlet flow path and the water spray pipe of the water jet propulsion pump 605 are all located at the bottom of the ship, directly providing the forward power to the ship. The function and control of the electric energy generated by the generator 503 are similar to those of the full electric propulsion wind energy ship, but the power is small, and the cost of the system is also greatly reduced. Since the steering and reversing of the ship are all carried out by the electric propeller 504, the water jet propulsion only performs the propulsion function, so the necessary control and reversing mechanism, hy...

Abstract

The invention discloses a vertical axis wind turbine and a wind energy ship with the same. The vertical axis wind turbine comprises a tower body (300), wherein a main shaft (108) which can rotate freely is arranged in the tower body (300); a cylindrical middle column body is arranged on the outer side of the main shaft (108); the middle column body is of a regular polyhedral frame structure which is formed by combining vertical columns (101) and cross beams (102), and is fixedly connected with the main shaft (108); the upper and lower groups of cross beams (102) or a plurality of upper and lower groups of cross beams (102) are provided with paddle arms (104) extending outwards; blades (400) are arranged on the paddle arms (104). The vertical axis wind turbine and the wind energy ship have the advantages of high structural strength and deformation resistance, more balanced and rational stress state, contribution to prolonging of service life of parts and high efficiency.

Description

technical field [0001] The invention relates to the field of wind energy utilization devices in the technical field of renewable energy utilization, in particular to a vertical axis wind turbine and a wind energy ship with the same. Background technique [0002] The utilization of renewable energy is currently a matter of great importance at home and abroad, and the mainstream product of wind energy utilization is the horizontal axis wind turbine, which has reached several megawatts at present. However, due to the inherent weaknesses in the structure of this type of wind turbine, such as the cantilever beam structure of the wind blades, the unbalanced load of the main bearing of the wind wheel, etc., the technical difficulty and development cost of further increasing the power of the single machine are greatly increased. So far it is difficult to get close to the 10 megawatt threshold. Compared with horizontal axis wind turbines, the development of vertical axis wind turbin...
