Embodiment 1

[0022] see figure 1 , a vertical axis wind turbine wind wheel height adjustment mechanism, including a main tower section 304, also includes a lifting section 305, the lifting section 305 is set in the main tower section 304 and can move in the main tower section 304, the wind wheel is installed on the lifting section 304 On the section 305; the main tower section 304 is provided with a tower lifting pulley block 309, one end of the main lifting cable is connected with the winch 308, and the other end is fixedly connected with the lifting section 305 after bypassing the lifting pulley block.

[0023] like image 3 As shown, it also includes a guiding mechanism guiding the lifting section 305. The guiding mechanism includes a lifting track 311 arranged on the main tower section 304 and a lifting track wheel 312 arranged on the lifting section 305. The lifting track wheel 312 can roll in the lifting track 311 . Lifting wheel rails or slide rails are used to limit the direction...

Embodiment 2

[0030] The lifting section 305 is a two-stage structure, including an upper lifting section 307 and a middle lifting section 306. The middle lifting section 306 is set in the main tower section 304, and the upper lifting section 307 is set in the middle lifting section 306; the middle lifting section 306 is provided with an upper tower lifting pulley 313 , one end of the upper tower lifting cable 314 is connected to the main tower section 304 , and the other end is connected to the upper lifting section 307 after bypassing the upper tower lifting pulley 313 .

[0031] The working principle of the tower lifting middle section 306 is the same as that of the two-stage tower lifting section 305 , and each system of the folding wind wheel is installed on the upper end of the tower lifting upper section 307 . Several pulleys are evenly installed on the upper end of the lifting middle section 306, and several cables of equal length pass through the respective pulleys, one end of which...

Embodiment 3

[0034] The multiple unique characteristics of the present invention can greatly expand its application range. Here, only the pumped storage wind power generation system is taken as an example. Image 6 It is a schematic diagram: use the terrain to build an energy storage reservoir at a high place, and the low place is a water source such as a reservoir, rivers and lakes, etc. On coasts and islands, if the problem of seawater corrosion is solved, seawater can even be used to store energy. In the figure, the wind turbine drives the water pump 901 to directly input the water in the lower part through the one-way valve 902 and the automatic regulating valve 904 of the water turbine into the water turbine generator 903 to generate electricity, or input the water into the reservoir for energy storage. When the wind is strong, the excess water is stored in the reservoir, and when the wind is weak, the insufficient water is replenished by the reservoir. As long as the capacity of th...

Abstract

The invention discloses a wind wheel height adjusting mechanism for a vertical axis wind turbine and a wind energy ship with the wind wheel height adjusting mechanism. The wind wheel height adjusting mechanism comprises a main tower section (304) and a lifting section (305), wherein the lifting section (305) is mounted in the main tower section (304) in a sleeving manner and can move in the main tower section (304); a wind wheel is mounted on the lifting section (305); a pylon lifting pulley block (309) is arranged on the main tower section (304); one end of a main lifting rope is connected with a winch (308); the other end of the main lifting rope bypasses the lifting pulley block and then is fixedly connected with the lifting section (305). The height of the wind wheel can be changed and locked according to the requirement; the system is matched with a paddle folding system, so that a force arm and destructive power of a destructive moment caused by hurricane can be greatly reduced, and the hurricane resisting capability of the wind turbine is further enhanced. In addition, the specific requirement of mobile wind energy utilization platform such as wind energy ships can be met, and the application field of the wind turbine is greatly widened.

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 wind wheel height adjustment mechanism and a wind energy ship with the same. Background technique [0002] At present, the height of the wind rotors of traditional lift-type wind turbines is fixed. This factor greatly limits the application fields of traditional wind turbines, and also affects the anti-hurricane ability of wind turbines, and even causes huge losses.
