Description

一种改进型的张紧油缸
(一)技术领域
本实用新型涉及应用于风力发电机系统部件领域，具体为一种改进型的张紧油缸。
(二)背景技术
大型的风力发电机离地面高，容易受到雷击，见图1，普通的张紧油缸其活塞杆2两端分别连接活塞头3和支撑环4，支撑环4、活塞杆2、活塞头3、缸筒1均为导电金属制成，当风力发电机遭到雷击时电流会沿着支撑环4、活塞杆2、活塞头3依次传递，由于活塞头3与缸筒1内壁之间的间隙只有0.1mm～0.2mm，活塞头3和缸筒1之间会出现放电现象，从而将缸筒1内壁和活塞头3表面的镀层打坏，使原本光滑的内壁变得毛糙不平整，破坏了密封组件5正常工作所必须的工作条件，使张紧油缸出现漏油现象，严重时还将破坏密封组件，造成张紧油缸内漏油严重，不能正常工作，提高设备维修保养的成本。
(三)发明内容
针对上述问题，本实用新型提供了一种改进型的张紧油缸，其能加大整个油缸的绝缘等级，有效避免雷击对张紧油缸的破坏，保证风力发电系统的正常工作，减少设备维护成本。
其技术方案是这样的：其包括缸筒和活塞杆，所述活塞杆两端分别连接有活塞头和连接支撑环，所述活塞头端插入所述缸筒内部，所述活塞杆与所述缸筒之间、所述活塞头与所述缸筒之间分别安装有密封组件，其特征在于：所述连接支撑环内安装有绝缘环。
其进一步特征在于：所述绝缘环为环氧树脂。
本实用新型的结构的张紧油缸，其通过加装绝缘环，阻断雷击时电流向张紧油缸的传递，避免了张紧油缸缸筒与活塞头之间放电，从而保护张紧油缸的安全，延长了张紧油缸的使用寿命，节约了维护保养成本。
(四)附图说明
图1为普通张紧油缸结构示意图；
图2为本实用新型的结构示意图。
(五)具体实施方式
见图2，本实用新型包括缸筒1和活塞杆2，活塞杆2两端分别连接有活塞头3和连接支撑环4，活塞杆2的活塞头端插入缸筒1内部，活塞杆2与缸筒1之间、活塞头3与缸筒1之间分别安装有密封组件5，连接支撑环4内安装有绝缘环6；绝缘环6为环氧树脂；图2中，7为气口，8为油口。

Claims (2)
