Abstract

The invention discloses a compressed air jet type self-starting vertical axis wind turbine and a detection method thereof. The compressed air jet type self-starting vertical axis wind turbine comprises a first impeller, wherein the first impeller is arranged on a power shaft and is used for being in power connection with a power generation device through the power shaft; a second impeller for driving the first impeller to rotate is correspondingly arranged on one side of the first impeller; a pressurizing tank is arranged between the second impeller and the first impeller; a shell of the pressurizing tank is arranged on the power shaft; an air jet hole is formed in the first impeller; an air conveying device is arranged on the pressurizing tank; the air conveying device communicates with the pressurizing tank and the air jet hole; air compression blades which rotate synchronously are arranged on the second impeller; and the air compression blades are arranged in an inner cavity of thepressurizing tank. According to the compressed air jet type self-starting vertical axis wind turbine and the detection method thereof, the problem that an existing vertical axis lift type wind turbinecannot be self-started or when resistance type blades are adopted to assist the lift type blades to start, the resistance type blades are prone to becoming a resistance source when the lift type blades rotate at a high speed is expected to be solved.

Description

technical field [0001] The invention relates to new energy wind power generation equipment, in particular to a compressed air jet type self-starting vertical axis wind turbine and a detection method thereof. Background technique [0002] With the progress of the times, the rational use of natural resources has received extensive attention, and wind turbines have been gradually put into the market to reduce the consumption of fossil energy and environmental pollution. Among them, the vertical axis wind turbine can utilize the wind energy blown from all directions because it does not need a steering mechanism, which has unique advantages compared with the horizontal axis wind turbine. [0003] Existing vertical-axis wind turbines generally use lift-type or drag-type blades. Lift-type vertical-axis wind turbines have higher wind energy utilization rates, but lift-type vertical-axis wind turbines cannot be self-started. They need to be equipped with motors to assist in starting,...
