The invention belongs to the technical field of helicopter rotor anti-icing and deicing, and particularly relates to a tail rotor collector ring and a helicopter tail rotor structure. Comprising a rotor assembly (1), the rotor assembly (1) is inserted into a stator assembly (2) and is coaxially arranged, and the rotor assembly (1) and the stator assembly (2) can relatively rotate around the central axis; one side of the stator assembly (2) is provided with an electric brush box (3); the rotor assembly (1) comprises a base (101), and conductive ring assemblies (102) are stacked on the side wall of the inner end, extending into the stator assembly (2), of the base (101); an electric brush (302) of the electric brush box (3) is electrically lapped with the conducting ring assembly (102), and the electric brush (302) is connected with the stator assembly (2) through an elastic sheet (301); water-drop-shaped grooves (104) are distributed in the outer end lip of the base (101) in the circumferential direction. The helicopter tail rotor anti-icing device can reliably transmit helicopter tail rotor anti-icing current and signals, and has the advantages of being small in size and capable of locating fault blades.

    本发明属于直升机旋翼防除冰技术领域,具体涉及一种尾桨集流环及直升机尾桨结构。包括转子组件(1),转子组件(1)插入定子组件(2)并同轴设置,转子组件(1)与定子组件(2)间能绕中轴线相对转动;定子组件(2)一侧安装有电刷盒(3);转子组件(1)包括基座(101),基座(101)伸入定子组件(2)的内端侧壁上堆叠有导电环组件(102);电刷盒(3)的电刷(302)与导电环组件(102)电搭接,电刷(302)经弹片(301)与定子组件(2)连接;基座(101)的外端唇口沿周向分布有水滴状槽(104)。本发明能可靠传输直升机尾桨防冰电流和信号,具有体积小、可定位故障桨叶的特点。
