Problems solved by technology

[0005] The purpose of the present invention is to address the deficiencies of the prior art and provide an offshore wind generator with a speed reduction device. By setting a first Venturi device and a second Venturi device on the tower, the first Venturi device The device and the second Venturi device are equipped with slide pipes, sliders and deceleration components, and one end of the first Venturi device and the second Venturi device is provided with a windshield component and a push component, which solves the problem of strong winds encountered by offshore wind turbines. When using wind power to effectively reduce the speed of the generator, the energy consumption is large, and the intelligence level is low, etc.

Embodiment 1

[0034] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0035] Such as Figure 1 to Figure 10 As shown, an offshore wind power generator with a speed reduction device includes a base 1, a tower 2 arranged on the base 1, a nacelle 3 arranged on the tower 2, a unit 4 arranged in the nacelle 3, and a set Several swing assemblies 6 on one end of the rotating shaft 5 of the unit 4, the first Venturi device 7 and the second Venturi device 8 are arranged on the tower 2, and the first Venturi device 7 and the second Venturi device 8 each includes a Venturi tube 9, a slide tube 10 extending o...

Embodiment 2

[0048] Such as Figure 4 As shown, the parts that are the same as or corresponding to those in Embodiment 1 adopt the reference numerals corresponding to Embodiment 1. For the sake of simplicity, only the differences between Embodiment 1 and Embodiment 1 are described below; the differences between Embodiment 2 and Embodiment 1 The difference is that: the air inlet 91 of the venturi tube 9 in the second venturi device 8 is fixedly provided with a bump 81 .

[0049] The bump 81 provided in this embodiment is used to limit the position of the windshield b139 during the reset process, so that the windshield b139 is just at the air inlet 91 of the Venturi tube 9, and can effectively block the air inlet 91. Wind also prevents the windshield b139 from slipping off.

Abstract

The invention relates to an offshore wind driven generator with a speed reduction device. The offshore wind driven generator comprises a base, a tower, a cabin, a unit and a plurality of swing assemblies arranged at one end of a rotating shaft of the unit. A first venturi device and a second venturi device are arranged on the tower, the first venturi device and the second venturi device each comprise a venturi tube, a sliding tube, a sliding block and a speed reduction assembly, and one ends of the first venturi device and the second venturi device are provided with a wind blocking assembly and a pushing assembly. The pushing assembly drives the wind blocking assembly to sequentially open air inlets of the venturi tubes in the first venturi device and the second venturi device, negative pressure areas are formed at the sliding tubes, the sliding blocks are pushed by air pressure to move up and down in the sliding tubes, and the speed reduction assemblies are driven to decelerate the rotating shaft. The offshore wind driven generator solves the problems that when an existing offshore wind driven generator encounters strong wind, a rotating shaft of the generator cannot be effectively decelerated through wind power, the energy consumption is large, and the service life of the generator is short.

Description

technical field [0001] The invention relates to the technical field of wind energy industry, in particular to an offshore wind power generator with a speed reduction device. Background technique [0002] Under the increasingly severe situation of oil resources, all countries have turned their attention to sea areas with huge wind resources. As a clean energy, wind power itself has many advantages, such as environmental friendliness, short construction period, and low operation and maintenance costs. The emerging offshore wind power is better than land wind power, and the huge windmill field has become a beautiful landscape. However, offshore generators also have the problem of excessive speed and damage to components when encountering strong winds, and the maintenance is relatively cumbersome. Therefore, a deceleration device is urgently needed to slow down the generator and prolong the service life of the generator. [0003] A Chinese invention with the publication number ...
