Abstract
The invention relates to a pressure compensation device of a wind-power conductive slip ring electric brush and belongs to the technical field of wind-power generation technologies. The pressure compensation device comprises two brush holders, two electric brush bodies, a tension spring, a mandrel, two fasteners and lead wires. An installing shaft is arranged at one end of each brush holder. An installing hole is formed in the other end of each brush holder. A spring connecting hole is formed in the middle position of each brush holder. The electric brush bodies and the brush holders are connected through the installing shafts on the brush holders and fixed through the fasteners. The two brush holders are connected through the mandrel and can peripherally rotate around the mandrel. The tension spring is connected with the two brush holders through the spring connecting holes. The lead wires are welded on the electric brush bodies. When slip rings or the electric brush bodies are abraded, the spring enables the two electric brush bodies to be tightened and enable contact to be firm. In addition, the electric brush bodies, the brush holders, the spring and other structural members are connected through screws in a spring-hook mode and are convenient and quick to replace.
Description
Technical field
The present invention relates to the pressure compensator of wind-powered electricity generation conducting slip ring brush, belong to technical field of wind power generation.
Background technology
The wind power generation conducting slip ring is to become the critical component of oar controlling organization and generator in wind turbine generator, play the function of control signal and current delivery under the blower fan rotation status, to realize two power transmitting devices that relatively rotate control signal and the current delivery of mechanism, can provide control signal for blower fan, also can export the energy endlessly from blower fan, be the core component of whole blower fan.And brush is the core part of conducting slip ring, its contact performance affects whole product quality.
Make a general survey of THE WIND ENERGY RESOURCES IN CHINA reserves and distribution thereof and show, China is vast in territory, the seashore line length, and wind energy resources is abundanter.In the middle of wind power generation is developing on a large scale, and the required general import external product of conducting slip ring of blower fan, cost is high, and the transportation maintenance is loaded down with trivial details, so the production domesticization of used for wind power generation conducting slip ring substitutes extremely urgent.
Brush is as the core part of wind-powered electricity generation conducting slip ring, and its contact performance, anti-wear performance will be the key factors that affects product quality, and contact performance and anti-wear performance depend on the coupling of friction pair and the adjusting of brush pressure.
Summary of the invention
The objective of the invention is in order to overcome in brush and slip ring relatively rotate process, the problem that the contact of the brush that the fretting wear of brush causes is inadequate, propose the pressure compensator of wind-powered electricity generation conducting slip ring brush.
The objective of the invention is to be achieved through the following technical solutions.
The pressure compensator of wind-powered electricity generation conducting slip ring brush of the present invention, this device comprises two brush holders, two brushes, extension spring, mandrel, two securing members and wire; One end of brush holder has installation shaft; The other end of brush holder has installing hole; There is spring connecting hole the middle part of brush holder;
Brush is connected by the installation shaft on brush holder with brush holder, and is fixed by securing member;
Between two brush holders, by mandrel, connect; Two brush holders can circumferentially rotate around mandrel;
Extension spring is connected by spring connecting hole with two brush holders; Be welded with wire on brush.
The other end of wire has the wire connector.
Extension spring adopts spring steel wire to be processed.
The flatness of surface of the electric brush is better than 0.01 μ m, and the roughness of brush cambered surface is better than Ra0.1.
Beneficial effect
The brush structure of general wind-powered electricity generation conducting slip ring adopts the mode of metal clips, the shortcoming of this mode is that the elastic deformation amount of brush own is very little, and the brush pressure adjustment is more difficult, easily makes shell fragment generation plastic deformation, the fixed form of brush and brush carrier is generally gluing mode, after fixing, brush position is stiff, and this also can bring difficulty to assembling, in addition when brush and slip ring wearing and tearing, the non-constant of the adaptive ability of shell fragment, the easy virtual connection of brush and slip ring, loose contact.And the mode that adopts the spring link is that assembling is than being easier to, and adjustability is more intense, after brush and slip ring have assembled, can adjust the spring tensile elongation according to moment of friction, thereby the adjustment spring tension, calculated the pulling force of spring, guarantees at maximum opening angle, spring, within regime of elastic deformation, reaches brush pressure and specifies requirement.When slip ring or wear of brush, spring can tighten up two brushes, makes contact firm.The structural members such as brush, brush holder, spring are all to adopt screw link, the link of spring carrier arm form in addition, change convenient and swift.
The accompanying drawing explanation
The structural representation of Fig. 1 device of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment
The pressure compensator of wind-powered electricity generation conducting slip ring brush, this device comprises brush holder A1, brush holder B2, brush A3, brush B4, extension spring 5, mandrel 6, securing member A7, securing member B8, wire A9 and wire B10, slip ring 11; The end of brush holder A1 has installation shaft; The other end of brush holder A1 has installing hole; There is the extension spring connecting hole middle part of brush holder A1; The end of brush holder B2 has installation shaft; The other end of brush holder B2 has installing hole; There is the extension spring connecting hole middle part of brush holder B2;
An installing hole is respectively arranged on brush A3 and brush B4;
Brush A3 is connected by the installation shaft on brush holder A1 with brush holder A1, and is fixed by securing member A7;
Brush B4 is connected by the installation shaft on brush holder B2 with brush holder B2, and is fixed by securing member B8;
Brush holder A1 is connected by mandrel 6 with brush holder B2; Brush holder A1 and brush holder B2 can circumferentially rotate around mandrel 6;
Extension spring 5 is connected with the spring connecting hole on brush holder B2 by brush holder A1;
Be welded with wire A9 on brush A3; Be welded with wire B10 on brush B4;
At the two ends of wire A9 and wire B10, a wire connector is respectively arranged, for being connected with the brush connector, the brush connector again with such as blower fan, generator are connected.
The course of work:
At first by the end welding lead of brush A3 and brush B4, the other end conducting wire connector of while wire, then the brush A3 of welding lead is connected with the installation shaft of brush holder B2 with brush holder A1 by the installing hole of brush A3 and brush B4 with brush B4, and be fixed by securing member A7 and securing member B8, after fixing, check, brush A3 and brush B4 can be around brush holder A1 and brush holder B2 axial rotation, by installing the brush holder A1 of brush A3 and brush B4 and the brush holder B2 connecting hole by brush holder A1 and brush holder B2 mono-end, with mandrel 6, linked, after link, check, brush holder A1 and brush holder B2 can be around mandrel 6 axial rotation, finally extension spring 5 is connected with the extension spring connecting hole at brush holder B2 middle part by brush holder A1, after connection by brush holder A1 and brush holder B2 opened with certain angle, and contacted with slip ring 11, when slip ring 11 rotates, slip ring 11 surfaces and brush A3 and brush B4 contact friction, in friction process, reason due to wearing and tearing, slip ring 11 and brush A3 and brush B4 can produce gap, extension spring 5 continues to contact with brush A3 and brush B4 because the pulling force self produced can make slip ring, keep good contact performance.
