Description
Technical field
The present invention relates to the anti-foreign matter Electrical Discharge Machine of a kind of efficiency, belong to field of generating equipment.
Background technique
In some office buildings and factory, in order to respond the call that national energy-saving reduces discharging, frequent meeting arranges some wind generating units at some ventilated ports, electricity generating device in these Environmental Conditions is different from grassland or deepwater large-scale wind generator set, first office building and the factory wind power plant that do not have spatial placement so large-scale, moreover office building and factory are generally in building dense district, the driving force of its wind is also more limited, so in office building and factory, some small-sized wind generating units can be used, to improve, the secondary of the energy is utilized, office building and plant environment are different from grassland environment simultaneously, in air, impurity content is higher, sometimes also can be mingled with some foreign matters such as the plastic tape be blown up or paper scrap simultaneously, these foreign matters are easy to result in blockage to wind power plant or be wound around, even equipment is stuck to cause the decrease of power generation of equipment,
So carry out anti-foreign matter transformation for the generator of the position such as factory and office building just seem particularly important, it solves the most important thing that can wind power generating set well use;
So in the prior art, different manufacturers proposes many similar structure or improvement, to improve the environmental resistance of these small-sized wind power generators.
As in ZL201110107189.0, its foreign matter mainly proposing a kind of wind generator unit wheel hub inside drops monitoring device, it is mainly through the detector of some rotations, to the monitoring that wind-driven generator inside is carried out repeatedly, if direction is dirty, it is also removed foreign matter mainly through an automatically controlled structure, and first this equipment can bring certain energy consume while using, because related sensor and the equipment such as route is unlucky all compare power consumption, be not suitable for the occasion that wind-force is less.
Simultaneously in 201420236257.2, which provide a kind of wind generator set of anti-soil formula, it mainly to be filtered the air stream entered by a multistage filter screen and prevents large-scale foreign matter from entering in vane group, and this kind of structure also exists very large deficiency, multistage filter screen can bring very large resistance, not only seriously can reduce the generating efficiency of generator, that also can reduce generator blade is subject to air quantity simultaneously, and filter screen itself is easy to break or block, finally causes air stream cannot enter on blade through filter screen and realize generating.
Summary of the invention
The technical problem to be solved in the present invention is: overcome anti-foreign matter wind-driven generator windage traditional in prior art large, the technical problem that generating efficiency is not high, provides the wind-driven generator that a kind of windage minor structure is fairly simple.
The technical solution adopted for the present invention to solve the technical problems is:
The anti-foreign matter Electrical Discharge Machine of a kind of efficiency, described generator comprises air conducting tube, impeller assembly, induction machine assembly, also comprise anti-assorted assembly, described impeller assembly is arranged on air conducting tube inside, described impeller assembly comprises an output shaft, described output shaft is connected with induction machine assembly, by the air stream drives impeller assembly being blown into air conducting tube, induction machine assembly is generated electricity, described anti-assorted assembly comprises lattice gear impeller, the edge of described lattice gear impeller is provided with an annular fixing frame, described lattice gear impeller is arranged on the intake grill of air conducting tube by the thin-wall bearing rotation that is arranged on fixing frame periphery, the lattice catch that the output shaft axis annular array that described lattice gear impeller comprises some relative impeller assemblies is arranged, in the middle part of lattice catch, an annular isolation net is provided with from the fixing frame of lattice gear impeller,
The overbending direction of described lattice catch is contrary with the overbending direction of impeller assembly Leaf, described isolation net comprises some some isolating rings be fixed on for circle with output shaft axle center on lattice catch, and the center that the diameter of described isolating ring keeps off impeller by lattice increases progressively towards the outside gradually.
As further innovation of the present invention, described impeller assembly comprises the turbine blade of a some spirality drive vane composition again.
As further innovation of the present invention, the quantity of described lattice catch is identical with the quantity of turbine blade.
As further innovation of the present invention, the cross section in the direction perpendicular to axial direction of described lattice catch is the thin wing shapes in thick middle both sides.
As further innovation of the present invention, the thickness of described lattice catch and isolation net contact segment is less than lattice catch and is positioned at the thickness that lattice keep off impeller central part.
The invention has the beneficial effects as follows:
1, the present invention is by a counter-rotational lattice gear impeller and the stop of isolation net realization to foreign matter being arranged on lattice gear vane edge, when foreign matter enters in air conducting tube, rotating backward end lattice gear impeller can by impurity pull-out or the lattice gear produced to a certain degree, prevent foreign matter from directly being sucked by impeller, cause equipment stuck.
2, isolation net of the present invention is while guarantee air-flow passing ability, lattice gear impeller can be improved again to the efficiency of isolation of foreign matter, compared to the filter screen in documents, its windage is lower, intensity is also higher, suppresses the isolation net rotated also to be less likely to occur the absorption of foreign matter simultaneously, eliminates the possibility that isolation net is blocked, isolation net have employed the support of some isolating rings simultaneously, has lower rotation windage and less weight.
3, the present invention passes through electricity generation impeller and the lattice gear impeller of contrary overbending direction, makes both rotate backward when air intake, just can not realize the eliminating of foreign matter by extra driving mechanism, further increase generating efficiency.。
4, the lattice catch of wing shape further can reduce windage, ensures the passing rate of air-flow, improves the efficiency of generating.
5, the present invention does not need by any control panel, only realizes point gear out of place to foreign matter with some Simple mechanical structures, does not need extra electric power supply, greatly improves the transformation efficiency between wind-force and electric power.
6, the impeller of turbo type can reduce the diameter of air conducting tube, while reducing generator volume, improves the efficiency of generating.
