Abstract

The utility model relates to a tower frame of a wind power generator, which is formed by mutually connecting more than one section of conical tower tube (1) and is characterized in that prismatic convex ribs (2) or square convex ribs (3) are arranged on the inner wall of the conical tower tube (1). The weight of the conical tower tube (1) disclosed by the utility model can be reduced by about 25 percent on the premise of ensuring the rigidity and intensity, about 20 percent of transportation, assembly and base cost can be saved, and the use is safe and reliable. The tower frame is applicable to the wind power generator.

Description

The pylon of wind-driven generator

Technical field

The utility model relates to the pylon of a kind of wind-driven generator, particularly a kind of wind-driven generator.

Background technique

Wind energy is best renewable green energy resource.In the conversion process of electric energy, ecotope is not produced destruction in wind energy.Compare the discharging that every 1000KW wind power generating set can reduce 151.52 tons of carbon dioxide, 9 tons of sulfur dioxide gas and 6 tons of CO (carbon monoxide converter) gas every year with the coal electricity.The wind energy reserves are big, and it is wide to distribute, and China has abundant wind energy resources.The theoretical reserves of wind energy resources are 32.26 hundred million kilowatts, and developable wind energy content is 2.53 hundred million kilowatts, occupies first of the world, with 3.8 hundred million kilowatts of developable total installed capacity of hydropower capacity be same magnitude, have the potentiality of commercialization, large-scale development.Along with the enhancing of people's environmental consciousness and the advanced person day by day of wind energy conversion system technology, wind-power electricity generation will be more safer and economical than in the past.Wind energy conversion system is the power plant that wind energy are converted to mechanical work, claims windmill again.Existing wind power plant, increase along with the power of the assembling unit, pylon is more and more higher, the wind-powered electricity generation set tower frame height of large-scale horizontal axis is above hundred meters, generator, speedup box and hydraulic system, cold and hot exchange system all are placed in the cabin and are supported by pylon, and the cabin is positioned in cat head, and this requires high to each part reliability, make the corresponding increase of manufacture difficulty and cost, installation, maintenance, the maintenance also very difficult.

The model utility content

The purpose of this utility model is to provide a kind of pylon of wind-driven generator, and this pylon structure is scientific and reasonable, can save material, transportation, assembling and basic cost about 20%, and is safe and reliable.

To achieve these goals, the technical solution adopted in the utility model is: a kind of pylon of wind-driven generator, comprise taper tower tube, and it is characterized in that: be provided with prismatic convex tendon or square convex tendon at taper tower tube inwall.

The beneficial effects of the utility model are: because after adopting such scheme, the utility model tower tube is under the precondition that guarantees rigidity and intensity, but weight reduction about 25% can be saved transportation, assembling and basic cost about 20%, and is safe and reliable.The utility model is applicable to wind-driven generator.

Embodiment

Be further described below in conjunction with the embodiment of Figure of description the pylon of a kind of wind-driven generator of the utility model.

Referring to Fig. 1--Fig. 2: the pylon of a kind of wind-driven generator of the present utility model, interconnect by the above taper tower tube 1 of a joint and to form, be provided with prismatic convex tendon 2 or square convex tendon 3 at taper tower tube 1 inwall.

As shown in Figure 3: be provided with prismatic convex tendon 2 at taper tower tube 1 inwall.

As shown in Figure 4: be provided with square convex tendon 3 at taper tower tube inwall.

Manufacture method of the present utility model is, the steel plate that is provided with prismatic convex tendon 2 or square convex tendon 3 is added the thermal bending welding make taper tower tube 1, the pylon of wind-driven generator generally is made up of the above taper tower tube 1 of two joints, the end assembly flange of taper tower tube 1, by bolt the flange of taper tower tube 1 end being linked together constitutes the pylon of wind-driven generator.

More than explanation is just illustrative for the utility model; and nonrestrictive, those of ordinary skills understand, under the situation of the spirit and scope that do not break away from claim and limited; can make many modifications, variation or equivalence, but all will fall within the protection domain of the present utility model.

Claims

1. the pylon of a wind-driven generator is interconnected by the above taper tower tube (1) of a joint and to form, and it is characterized in that: be provided with prismatic convex tendon (2) or square convex tendon (3) at taper tower tube (1) inwall.
