Embodiment 1

[0044] refer to Figure 1 to Figure 10 As shown, one embodiment of the present invention is a compressed air jet self-starting vertical axis wind turbine, including a first impeller 1, the first impeller 1 is installed on the power shaft 2, and is used for connecting the power shaft 2 and the power generation device. Power connection, wherein the power generating device can be a generator A, the first impeller 1 is an existing lift-type impeller mechanism, the first impeller 1 rotates to drive the power shaft 2 to rotate, and the power shaft 2 drives the generator A to work, and the generator Machine A generates electricity.

[0045] One side of the first impeller 1 is correspondingly provided with a second impeller 3, that is, a second impeller 3 is provided below or above the first impeller 1 to assist the rotation of the first impeller 1, wherein the second impeller 3 is an existing resistance type impeller mechanism, thus, the second impeller 3 can start automatically und...

Embodiment 2

[0051] Based on the above-mentioned embodiment, another embodiment of the present invention, the above-mentioned pressurized tank 4 includes a tank body 401, and the above-mentioned tank body 401 is provided with a pressurized chamber 402 and a high-pressure chamber 403, wherein the pressurized chamber 402 has the function of air pressure boosting , the high pressure chamber 403 plays the role of buffering the air flow. The lower end of the above-mentioned pressurized chamber 402 is provided with an air inlet 404 with an opening downward. By placing the air inlet 404 of the pressurized chamber 402 downward and opening downward, dust accumulation in the pressurized chamber 402 can be effectively avoided.

[0052] It should be noted that, under the premise of ensuring that the intake air volume of the air inlet 404 meets the demand, for the environment in which the wind turbine is used, an anti-foreign body cover 407 with air flow holes can be installed on the air inlet 404, so a...

Embodiment 3

[0058] Based on the above examples, refer to Figure 3 to Figure 5 As shown, in another embodiment of the present invention, the above-mentioned power shaft 2 is hollow, the above-mentioned power shaft 2 is provided with a tower rod 8, the above-mentioned tower rod 8 is provided with a first bearing 801, and the movable end of the above-mentioned first bearing 801 is connected to the power shaft 2 The inner wall, that is, the tower rod 8 is a support rod, and the power shaft 2 is installed on the outside of the tower rod 8 through the first bearing 801, so that the power shaft 2 can rotate when the tower rod 8 is in a static state.

[0059] The lower end of the power shaft 2 is provided with a bevel gear 201 for power connection with the generator A through the bevel gear 201 .

Abstract

The invention discloses a compressed air jet type self-starting vertical axis wind turbine and a detection method thereof. One side is correspondingly provided with a second impeller that drives the first impeller to rotate, a booster tank is provided between the second impeller and the first impeller, the housing of the booster tank is installed on the power shaft, and a booster tank is installed on the first impeller. There is an air injection port, and the above-mentioned pressurized tank is provided with an air delivery device, and the above-mentioned air delivery device is respectively connected to the pressurized tank and the air injection port, and the above-mentioned second impeller is provided with synchronously rotating compressed air blades, and the above-mentioned compressed air blades are placed in the pressurized tank In the cavity, in order to improve the problem that the existing vertical axis lift wind turbine cannot start automatically, or when the resistance blade is used to assist the lift blade to start, the resistance blade is likely to become a resistance source when the lift blade rotates at high speed.

Description

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