Description
Technical field
The utility model relates to a kind of wind generating unit, specifically a kind of wind generating unit that has wind-collection cover.
Background technique
Along with the pressure increase of energy and environment, clean reproducible new energy and be subjected in recent years generally paying attention to.In all kinds of green energy resources, wind energy is one of renewable energy sources of having a high potential of prospect, utilizes wind energy power to receive publicity day by day and shows wide growing space.China's wind energy aboundresources, the development wind-powered electricity generation has a high potential, and gross reserves reaches 32.26 hundred million kilowatts, ranks first in the world, and the large-scale promotion wind-powered electricity generation can be made positive contribution for energy-saving and emission-reduction.
But, because the energy density of wind energy is low, unstable this natural characteristic of wind-force, cause some regional wind generating units the unsettled situation of generating rate often to occur, if reduce the diameter of pneumatic equipment blades made, the situation that can adapt to weak wind-force, but generating efficiency is low, can not effectively utilize wind resource; The diameter of machine blade if breeze up can not continue generating again under weak wind condition.So just be unfavorable for the promotion and application of wind energy power technology.
The model utility content
The purpose of this utility model is the deficiency that overcomes above-mentioned technology, provides a kind of easy for installation, applied widely, and low cost of manufacture can better be gathered the electricity generating device of wind energy.
For realizing above-mentioned technical purpose, the utility model provides following technological scheme:
A kind of wind generating unit, comprise wind energy conversion system, generator, movable pylon, fixed gantry, rolling supporting structure, movable pylon is connected with fixed gantry by the rolling supporting structure, it is characterized in that: the place, windward side of described wind energy conversion system is provided with a wind-collection cover, has one group of fixed support one end to be fixed on the wind-collection cover, and the other end is fixed on the movable pylon.
It is tubular that described wind-collection cover is circular cone, the end that its diameter is big is an intake grill, and the end that diameter is little is an exhaust outlet, and the shaft axis of described wind-collection cover is coaxial with the center line of wind energy conversion system, exhaust outlet is near wind energy conversion system, and the diameter of exhaust outlet is more than or equal to the diameter of wind energy conversion system surface of revolution.
Exhaust outlet to the distance of pneumatic equipment blades made windward side is a 0.2-3 rice on the described wind-collection cover.
Intake grill diameter on the described wind-collection cover and exhaust outlet diameter ratio are 2-4: 1
The inwall of described wind-collection cover is provided with the helical groove that is extended to the exhaust outlet direction by intake grill, and the sense of rotation of described helical groove is consistent with the Hand of spiral of wind energy conversion system upper blade.
Described wind-collection cover adopts stainless steel to make, or forms at the outside Tarpauling that coats of steel skeleton.
Compare with existing wind generating unit, the beneficial effects of the utility model mainly contain:
1. the utility model has adopted wind-collection cover, the profile of wind-collection cover is the conical tube shape, and the diameter of section of intake grill is greater than the diameter of section ratio of exhaust outlet, can active set wind gathering energy, the wind resource utilization ratio is higher, is suitable for the low unsettled again area of wind energy density and uses.
2. because wind energy conversion system is mounted in the right opposite that facings the wind of wind-collection cover, what just be in wind-collection cover goes out the wind snout place, more helps bringing into play the optimum operation efficient of wind energy conversion system.And the interior wall construction of wind-collection cover shape groove in the shape of a spiral, its Hand of spiral is consistent with the rotation direction of wind energy conversion system, the wind-force that converges finally also in the shape of a spiral shape pass through from exhaust outlet, this moment wind speed and blast will significantly be improved, correspondingly improved the stability of wind energy power.
3. the utility model is simple in structure, and is easy to make, and generating efficiency is higher, the needs that can adapt to different regions development wind-power electricity generation, be particularly suited for promoting,, share this environmental protection resource to make full use of and to develop wind generating technology in the low unsettled again area of wind energy density.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of wind-collection cover 1 among Fig. 1.
Among the figure: wind-collection cover 1, fixed support 2, wind energy conversion system 3, generator 4, movable pylon 5, rolling supporting structure 6, fixed gantry 7, basis 8, exhaust outlet 9, intake grill 10.
Embodiment
Below in conjunction with description of drawings and embodiment the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of wind generating unit, comprise wind energy conversion system 3, generator 4, movable pylon 5, fixed gantry 7, rolling supporting structure 6, movable pylon 5 is connected with fixed gantry 7 by rolling supporting structure 6, and the place, windward side of wind energy conversion system 3 is provided with a wind-collection cover 1, have one group of fixed support 2 one end to be fixed on the wind-collection cover 1, the other end is fixed on the movable pylon 5.
Concrete making and implementation step are as follows:
The first step; Make wind-collection cover 1
The material that wind-collection cover 1 is selected for use can be a stainless steel, or Tarpauling.When doing wind-collection cover 1, can directly its inwall be made spiral helicine groove with stainless steel material; When making, to do a steel skeleton earlier, equally also the inwall of framework will be made spiral helicine groove of canvas, then with Tarpauling to coating inside and outside it.Wind-collection cover 1 profile of making is the conical tube shape, and interior wall construction is spiral helicine groove, and allows its intake grill 10 diameters and exhaust outlet 9 diameters ratio be 2-4: 1.
Second step: finish installation
After wind-collection cover 1 is made, exhaust outlet 9 one side subtend wind energy conversion systems 3, one side of intake grill 10 outwardly, and the shaft axis that will guarantee its shaft axis and wind energy conversion system 3 is on same axis, make the helical groove of wind-collection cover 1 inwall consistent with the Hand of spiral of wind energy conversion system 3 upper blades, its exhaust outlet 9 to the distance of wind energy conversion system 3 blade windward sides remains in the scope of 0.2-3 rice, then, is fixed on the movable pylon 5 with one group of fixed support 2.Movable pylon 5 is connected with fixed gantry 7 by rolling supporting structure 6, and fixed gantry 7 is fixed on the basis 8.
After the wind-force intake grill 10 bigger by area enters wind-collection cover 1, the circulating direction of wind also can change along with the helical groove of inwall, and finally also in the shape of a spiral shape pass through from exhaust outlet 9, form the jet pipe effect, the wind energy that converges of this moment can significantly improve, and the wind energy conversion system 3 that promotes to be installed in wind-collection cover 1 spout place rotates, and then drives generator 4 generatings.And because the rotation of wind-collection cover 1 and movable pylon 5 is homoaxial synchronously, rolling supporting structure 6 is convex symmetrical roller bearings entad, can horizontally rotate; When change of the wind, the angle of wind-collection cover 1 rotation just can be rotated automatically along with the change of wind direction, and realizes automatic wind direction adjusting so, just further improving the stability of wind-power electricity generation.
