Embodiment Construction

[0018] In order to clearly illustrate the structure and positional relationship of the present invention, the following descriptions all use figure 1 The left side is the front, and the right side is the back.

[0019] refer to Figure 1-3 As shown, the present invention provides a wind power generating set with stall adjustment, including blade 1, hub 8 and mounting plate 3, each fan blade 1 is respectively mounted on its own mounting plate 3, and each mounting plate 3 can be moved back and forth It is swingably installed on the hub 8, and is provided with an elastic assembly that limits the front and rear swing range of the mounting plate 3. The axis of the blade 1 itself and the swing axis of the mounting plate 3 form an acute angle on the windward side (that is, image 3 γ angle shown).

[0020] Specifically, each fan blade 1 can be fixedly connected to the blade mounting plate 3 via bolts 2, a hinge shaft 7 is installed on the hub 8, and the mounting plate 3 is connecte...

Abstract

The invention relates to a wind power generation unit with stall regulation. The wind power generation unit comprises vanes, a hub and installation boards, wherein the vanes are respectively arranged on each installation board, the installation boards can be arranged on the hub in a back-and-forth swinging way and are provided with elastic assemblies which are used for limiting the back-and-forth swing amplitude of the installation boards, and an acute angle is formed between axes of the vanes and the swing axes of the installation boards at a windward side. According to the wind power generation unit disclosed by the invention, the structure is simple, the execution power is large, the reliability is high, and the cost is low.

Description

technical field [0001] The invention relates to the field of regulation of wind power generators, in particular to a wind power generator with stall regulation. Background technique [0002] Most of the adjustment methods of off-grid small wind turbines adopt centrifugal adjustment, that is, the main shaft drives the centrifugal flyweight to balance the centrifugal force of the flyweight and the spring force, so that the blades rotate around their own axes and change the pitch angle, so as to achieve the purpose of speed regulation. The structure of the centrifugal adjustment mechanism is relatively complicated, the maintenance workload is large, the execution force is small, it is easy to jam, and the reliability is low. [0003] Existing wind power generators obviously still have inconvenience and defects in adjusting structure and use, and need to be further improved urgently. How to create a wind turbine with stall regulation that has a simple structure, low cost, and c...
