Abstract

The utility model discloses a wind electricity generating device in a flow guiding and pressure increasing swirl type, which comprises one or a plurality of generator sets composed of a plurality of flow guiding passages and a generator, a gear box and a wind machine fixed on a wall of center parts of the flow guiding passages, wherein the flow guiding passages are formed by the enclosure of a wall body assembling towards the center parts of the flow guiding passages and the cross section of the wall body is smooth curves. The utility model basically blocks off reverse wind and enables the linear wind of any direction more than third stage to form the swirl wind of high flowing speed of tangential entrance on the center parts of the flow guiding passages by flow guidance and pressure increase to increase the conversion efficiency of wind energy. The utility model has the advantages of low cost, low adapting wind stage, easy manufacture and convenient installation and maintenance. The utility model is particularly suitable for deserts, gobi areas, mountainous areas and other areas with bad geological conditions and weather conditions. The utility model has no contamination generation and good environment protecting benefit. The utility model can also replace a shielding product for shielding wind and sand in the deserts, the gobi areas or other places particularly requiring protection.

Description

Water conservancy diversion supercharging rotary flow type wind generating unit

One, affiliated technical field:

The utility model belongs to wind generating unit.

Two, background technique:

At present, power shortages have been the bottlenecks of restriction Chinese national economy development, because of being subjected to the restriction of environment and resource, traditional generation mode is hard to carry on based on the electric power fondational structure of hydroelectric power and thermal power generation, 70% of China's electric power comes from the thermal power plant at present, and the discharging of sulfur dioxide also is mainly derived from the thermal power plant in the atmosphere, and country causes 110,000,000,000 yuans loss because of acid rain harm is annual to country.Therefore, greatly develop clean energy resource, renewable energy sources is the task of top priority.China's wind resource is abundant, the area of northern desertization particularly, and disaster caused by a windstorm, sandstorm are also very serious, and the development wind-power electricity generation should be the first-selection of clean energy resource.China's wind-power electricity generation is started late, also main dependence on import equipment of wind power station at present few in number or importing technology, and cost is than higher, thereby cost of electricity-generating is lacked competitiveness on electricity market also than higher.Existing wind generating unit all is to adopt tower paddle-shaped wind-driven generator basically, and this equipment is to the material capability of blade, and manufacture process requirement is than higher, complex process; This apparatus control system (comprising heading control loop down with the wind) is complicated especially, thereby involves great expense, and its suitable wind-force is the 4-8 level, and it is narrow to be suitable for wind scale.The task of top priority be explore one practical, cheap, operating cost is low, scale is changeable, be convenient to the new way promoted rapidly.

Three, summary of the invention:

The utility model is exactly to solve now with the problems referred to above that exist in the technology, provides a kind of with low cost, simple in structure, and environmental conditions is required low water conservancy diversion supercharging rotary flow type wind generating unit.

For addressing the above problem, technical solution of the present utility model is: a kind of water conservancy diversion supercharging rotary flow type wind generating unit, it comprise one or more by a plurality of guide channels, be fixed on the generator set that wind energy conversion system, gearbox and generator on the body of wall in guide channel center portion are formed; The body of wall that guide channel is compiled to the guide channel center portion by multiple tracks surrounds, and wall section is a smoothed curve.

Wind energy conversion system of the present utility model is for the main shaft vertical ground is arranged, the bending blade concave surface is in face of the antecurvature formula wind energy conversion system of air intake direction.

The body of wall of guide channel of the present utility model evenly distributes around the guide channel center portion.

Body of wall of the present utility model can be steel structure and masonry concrete structure.

Wall section of the present utility model is circular arc.

The guide channel that the cross section that the utility model is compiled to the guide channel center portion by multiple tracks surrounds for the smoothed curve body of wall, the straight line wind more than three grades of ground surface any direction can be formed the eddy flow wind of the high flow rate that tangentially enters by the water conservancy diversion supercharging in the center portion of guide channel, improve the conversion efficiency of wind energy greatly.The used material of guide channel of the present utility model and lower than the condition of tower paddle-shaped wind-driven generator to the requirement of blower fan, generator, and do not need the baroque heading control loop of facining the wind, it is with low cost, and is simple in structure.Can select to make the size of generator according to the needs of actual power amount, but single generator set, also a plurality of generator set.It is low that it adapts to wind scale, and gentle breeze just can make its generating, and to the big wind of wind scale without limits, it is made easily, is convenient to installation and maintenance, is easy to popularization, and Applicable scope is wide.Utilize wind-power electricity generation, do not produce pollutant, environmental benefit is good; And in the desert, the place of Gobi desert or special requirement protection, not only can generate electricity, can also replace screen shielding dust storm.

Four, description of drawings

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a plan view of the present utility model;

Fig. 2 is a plan view of the present utility model.

Five, embodiment:

As shown in Figure 1 and Figure 2, present embodiment comprise one by four guide channels, be fixed on the generator set that wind energy conversion system, gearbox 6 and generator 7 on the body of wall of guide channel center portion are formed; Four guide channels are surrounded by the body of wall 1 that four roads compile to the guide channel center portion, and body of wall 1 cross section is a circular arc, and it evenly distributes around the guide channel center portion.Wind energy conversion system is that main shaft 5 vertical grounds are arranged, blade 3 curved concave are in face of the antecurvature formula wind energy conversion system of air intake direction.Body of wall 1 is a steel structure.Wind energy conversion system main shaft 5 two ends are fixed on the body of wall 1 by fixed support 2 and bearing 8, and its main shaft 5 connects generator 7 main shafts by gearbox 6; Bearing is positioned at bearing chamber 4.

Also six or three or five of guide channels of the present utility model, it is surrounded by the body of wall that six roads or three roads or five roads compile to the guide channel center portion.Wall section be shaped as a parabolical part or a hyp part.
