Description
Technical field
The present invention relates to a kind of wind instrument, specifically be meant a kind of wind instrument based on the magnetic induction type of heating.
Background technology
At present, the wind instrument that is applied to wind-power electricity generation freezes and causes the phenomenon of aerogenerator cisco unity malfunction at Chinese north of china in winter ubiquity.Because the vane and the wind wing of wind instrument all are rotary parts, can not directly power, existing wind instrument all mainly adopts the resistance wire or other electro-heat equipment that are installed on its shell to heat up, and the vane or the wind wing are heated by thermal-radiating mode, to eliminate freezing on the wind instrument shell, guarantee the normal use of wind instrument.
Yet, because heat radiation is to launch to all directions, and its efficient is far below heat conducting heat transfer type, therefore, even very big heating power can not guarantee wind instrument operate as normal at low temperatures, its most of heat all is dissipated in the air, and this worldwide all is an open question.Simultaneously, the effect when adopting traditional approach to carry out heat radiation, therefore also very high to the performance requirement and the quality requirements of heater members, thus increased the cost of manufacture of this wind instrument virtually, be unfavorable for extensively promoting and using.
Summary of the invention
The objective of the invention is to overcome these wind instruments cisco unity malfunction and the higher defective of cost of manufacture under cryogenic conditions at present, provide a kind of not only simple in structure, and has a higher thermal radiation efficiency, can guarantee wind instrument operate as normal under cryogenic conditions, and the lower wind instrument based on the magnetic induction type of heating of cost of manufacture.
Purpose of the present invention is achieved through the following technical solutions: based on the wind instrument of magnetic induction type of heating, mainly form by connecting link, shell and the rotating shaft that is arranged at enclosure, described connecting link is positioned at the outside top of shell and is connected with rotating shaft, and also is provided with the heater that is connected with connecting link and can rotates around shell in the outside of shell.Also be provided with in the inboard of this heater and be fixed on the alternating magnetic field generating means that is used to produce alternating magnetic field on the shell, and be connected with this alternating magnetic field generating means and provide the high-frequency circuit of high-frequency current for it.
In order better to realize the present invention, described alternating magnetic field generating means has following three kinds of frame modes, first kind of structure is: described alternating magnetic field generating means is provided with the disc skeleton of bearing by inside, be distributed in this disc skeleton periphery and be embedded in the magnetic conduction bar more than of its inside, and the coil that is wrapped on this disc skeleton sidewall is formed, described bearing tightly is enclosed within on the shell, and coil then is connected with high-frequency circuit.
Second kind of structure is: described alternating magnetic field generating means is provided with the disc skeleton of bearing by inside, be distributed in the magnetic conduction bar more than on this disc skeleton sidewall, and be wrapped in every coil on the magnetic conduction bar and form, described bearing tightly is enclosed within on the shell, and each coil all is connected with high-frequency circuit.
The third structure is: described alternating magnetic field generating means is provided with the disc skeleton of bearing by inside, be arranged on the disc skeleton inner and along its periphery equally distributed more than one the magnetic conduction bar and be arranged on this disc skeleton end face and the coil of shape coiling is in the shape of a spiral formed, described bearing tightly is enclosed within on the shell, and this coil then is connected with high-frequency circuit.
For the ease of using the present invention, on described connecting link, also be provided with the vane or the wind wing.
Further, described heater is made by permeability magnetic material, and this permeability magnetic material preferentially adopts manganese-zinc ferrite or nickel-zinc ferrite.Described magnetic conduction bar then is made by manganese-zinc ferrite or nickel-zinc ferrite.
The present invention compares than prior art, has the following advantages and beneficial effect:
(1) the present invention has adopted the magnetic induction type of heating to come wind instrument is heated, be that heater of the present invention can cut the alternating magnetic field that the alternating magnetic field generating means is produced when rotating synchronously along with rotating shaft, thereby the generation heat, and with this heat transferred wind instrument.Because this heat is directly to be undertaken by thermaltransmission mode, rather than adopts traditional heat radiation mode to carry out, so its heat transference efficiency is very high, can guarantee that wind instrument normally uses under cryogenic conditions.
(2) because magnetic field possesses very strong directivity, after the alternating magnetic field generating means produces friendship table magnetic field, have only the heater of high magnetic conduction to generate heat, miscellaneous part then can not generate heat, so this type of heating possesses very high directive property.
(3) the present invention adopts after the magnetic induction type of heating, only need heater is adopted induction heating, need not to increase new electric and mechanical connecting element, therefore can reduce the overall power load of whole wind instrument widely, and then reduce the cost of manufacture of wind instrument greatly sensor-based system.
(4) according to testing under-20 ℃ of environment temperatures, traditional heating mode can prevent just that when 160W wind speed and direction from freezing, but adopt after the magnetic induction type of heating of the present invention, even when 40W, just can change ice (as a rule change the needed thermal power of ice will far above the thermal power that prevents to freeze), therefore the thermal efficiency of the present invention is more than 4 times of traditional approach at least.
