Embodiment 1

[0049] Provide a wind turbine blade deicing system, the deicing system includes a blower 5, a heating device 6, a multi-air slip ring 11 and three blade ventilation ducts 4, the multi-air slip ring 11 includes a multi-air slip ring The air inlet 21 of one pass, the multi-air slip ring rotor 25 and the air duct 24 of the rotor side of the one pass multi-air slip ring go to the blade; The air slip ring rotor side goes to the ventilation duct 24 of the blade to communicate with the blade ventilation duct 4 respectively, and a straight-through air slip ring 9 is respectively installed in the ventilation duct 24 of the air slip ring rotor side to the blade; The air slip ring 11 is installed on the support one 14, and the support one 14 is installed in the hubcap 2.

[0050] The one-pass multi-air slip ring 11 includes a rotor part and a stator part, and the rotor part includes a support 14, a one-pass multi-air slip ring rotor 25 and a one-pass multi-air slip ring rotor side to the...

Embodiment 2

[0054] A wind power generating set is provided, comprising a nacelle 1, a hubcap 2, blades 3 and a blade deicing system, the blade deicing system comprising a blower 5, a heating device 6, a multi-air slip ring 11 and three blade ventilation ducts 4 , a multi-air slip ring 11 includes an air inlet 21 of a multi-air slip ring, a rotor 25 of a multi-air slip ring, and a ventilation duct 24 going to the blade from the rotor side of a multi-air slip ring; the air inlet of a multi-air slip ring 11 The pipeline 15 is communicated with the air outlet of the heating device 16, and the ventilation duct 24 that goes to the blade on the rotor side of a multi-gas slip ring is communicated with the ventilation duct 4 of the blade, and the ventilation duct 24 that goes to the blade from the rotor side of a multi-gas slip ring is respectively installed with A straight-through air slip ring 9; the one-pass multi-air slip ring 11 is installed on the support one 14, and the support one 14 is ins...

Embodiment 3

[0065] This embodiment provides a wind power generating set. The difference between this embodiment and Embodiment 1 is that both the blower 5 and the heating device 6 are located in the hubcap 2, and the blower 5 and the heating device 6 pass through the blower and the heating device. The heating device installation bracket 18 is installed on the side flange of the nacelle. Therefore, there are no air inlets 44 and air outlets 45 on the hub windshield 13 . The hub of the generating set and the interior of the blades 3 form a relatively airtight space, and the blower 5 directly sucks cooling air from the hubcap 2 .

Abstract

The invention provides a wind generating set blade deicing system and a wind generating set. The wind generating set comprises a cabin, a hub cap, blades and the deicing system. The deicing system comprises an air blower, a heating device, a one-way multi-air slip ring and three blade ventilating ducts. An air inlet of the one-way multi-air slip ring is communicated with an air outlet of the heating device through a pipeline, a ventilating pipeline from the rotor side of the one-way multi-air slip ring to the blades is respectively communicated with a blade ventilating pipeline, a straight-through air slip ring is respectively arranged in the ventilating pipeline from the rotor side of the one-way multi-air slip ring to the blades, and the one-way multi-air slip ring is installed on a first support, and the first support is installed in the hub cap. The invention relates to an air heating deicing technology, and provides an integrated air heating deicing structure without replacing a slip ring, and compared with the prior art, the integrated air heating deicing structure has the advantages of obvious cost advantage, short construction period, simple structure, high safety and good application prospect.

Description

technical field [0001] The present invention relates to the technical field of wind power generation, and more specifically, to a blade deicing system of a wind power generator set and the wind power generator set. Background technique [0002] Wind turbines are usually installed in mountainous or plateau areas with high altitude, low temperature, and high humidity. In these areas, with the decrease of temperature and increase of humidity in winter, the outer surface of wind turbine blades is very easy to be covered with ice. Icing of blades will not only cause The shutdown of the unit may also cause the vibration of the turbine unit or the distortion of the power factor and endanger the operation of the unit, thus causing huge economic losses to the wind farm and seriously threatening the safety of equipment operation. [0003] The anti-icing technology of wind turbine blades is divided into two types: passive anti-icing and active deicing. Active deicing is mostly applied ...
