Problems solved by technology
Through the protection mechanism of manual operation, on the one hand, it is necessary to monitor the wind force in real time, which has high labor costs; Inside, the wind power generation equipment is overloaded
Therefore, wind power generation equipment will inevitably be overloaded, so the protection effect of wind power generation equipment is not ideal
Moreover, the overload protection in the prior art cannot be adjusted accordingly according to the wind force, and it is impossible to ensure that the wind turbine generates electricity normally while realizing adaptive overload protection.

Embodiment Construction
[0034] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.
[0035] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

The invention relates to a wind driven generator based on a linear type grading wind power braking device. The wind driven generator comprises a supporting frame, a power generation device, a wind power transmission device, fan blades and the grading wind power braking device. The power generation device is arranged on the supporting frame and is in driving connection with the wind power transmission device. The wind power transmission device is in driving connection with fan blades, and the grading wind power braking device is connected with the wind power transmission device. The grading wind power braking device comprises a sail, a first-stage wind power braking mechanism and a second-stage wind power braking mechanism, the first-stage wind power braking mechanism is in driving connection with the sail, and the second-stage wind power braking mechanism is in driving connection with the first-stage wind power braking mechanism. The first-stage wind power braking mechanism and the second-stage wind power braking mechanism are further connected with the wind power transmission device. According to the wind driven generator based on the linear type grading wind power braking device, grading protection on the wind driven generator is achieved through the grading wind power braking device, overload operation of the wind driven generator is avoided, and therefore the service life of the wind driven generator is prolonged.
Description
technical field [0001] The invention relates to the technical field of wind power generators, in particular to a wind power generator based on a linear graded wind braking device. Background technique [0002] Wind power generation is the process of converting wind energy into mechanical energy and then converting mechanical energy into electrical energy. This process does not require fuel, has no radiation, and has no pollution to the air and the environment. Therefore, wind energy is a clean energy source. [0003] However, the wind power input to the wind power generation equipment is not artificially set, but is taken from the magnitude of the natural wind in the working environment where the wind power generation device is located, that is, the magnitude of the wind power driving the wind power generation device is not controllable. At present, the wind power generators on the market are prone to overload operation due to excessive wind force, and eventually the wind p...
