Embodiment 1
[0031] Such as figure 1 as shown,
[0032] A low-noise and high-efficiency wind blade includes a blade root, a wingspan, a blade tip, a noise reduction component, and a wind guide component.
[0033] The blade root is located at the root of the entire wind blade, and is connected to the impeller hub of the wind generator at the blade root connection at the root, so as to fix the entire wind blade on the impeller hub.
[0034] The wingspan part is located between the blade root and the blade tip, its width gradually increases from the blade root, then extends to the blade tip and then gradually decreases, and the interior is partially hollow to form an air guide channel communicating with the blade tip .
[0035] The blade tip is provided with an air outlet of the air guide channel at one end of the tip.
[0036] The noise reduction parts are made of thin rubber strips, including the noise reduction parts of the blade root, the noise reduction parts of the wingspan, the nois...
Embodiment 2
[0054] Such as figure 1 with figure 2 Shown: a low-noise and high-efficiency wind blade, including a blade root, a wingspan, a blade tip, a noise-reducing component, and a wind-guiding component.
[0055] The blade root is located at the root of the entire wind blade, and is connected to the impeller hub of the wind generator at the blade root connection at the root, so as to fix the entire wind blade on the impeller hub.
[0056] The wingspan part is located between the blade root and the blade tip, its width gradually increases from the blade root, then extends to the blade tip and then gradually decreases, and the interior is partially hollow to form an air guide channel communicating with the blade tip .
[0057] The blade tip is provided with an air outlet of the air guide channel at one end of the tip.
[0058] The noise reduction parts are made of thin rubber strips, including the noise reduction parts of the blade root, the noise reduction parts of the wingspan, th...
Embodiment 3
[0074] A low-noise and high-efficiency wind blade includes a blade root, a wingspan, a blade tip, a noise reduction component, and a wind guide component.
[0075] The blade root is located at the root of the entire wind blade, and is connected to the impeller hub of the wind generator at the blade root connection at the root, so as to fix the entire wind blade on the impeller hub.
[0076] The wingspan part is located between the blade root and the blade tip, its width gradually increases from the blade root, then extends to the blade tip and then gradually decreases, and the interior is partially hollow to form an air guide channel communicating with the blade tip .
[0077] The blade tip is provided with an air outlet of the air guide channel at one end of the tip.
[0078] The noise reduction parts are made of thin rubber strips, including the noise reduction parts of the blade root, the noise reduction parts of the wingspan, the noise reduction parts of the blade tip and...
