Abstract

本实用新型涉及一种采油井口防盗装置,它由井口、井口接头、压帽、压套组成,井口接头接在井口上,压套与井口接头由键固定,压帽与井口接头螺纹连接,在压帽和压套之间开有相连通的孔,孔中设有弹簧,弹簧顶住销子和锁芯,只有用钥匙插入锁芯内压柱销子才能将压帽旋开。本实用新型具有结构简单、防盗性能好、抗破坏能力强等优点。

Description

采油井口防盗装置
本实用新型涉及一种采油井口防盗装置,属石油开采领域。
目前油田井场上使用的采油井口装置由压帽、压套、井口、盘根等组成,偷盗者只要旋出压帽,盘根和压套即被原油压力顶出,原油从盘根处流出而被盗,给国家造成不可估量的损失。
本实用新型的目的在于克服现有技术的缺点,提供一种采油井口防盗装置。
本实用新型的目的是这样实现的:采油井口防盗装置由井口、井口接头、压帽、压套组成,井口接头接在井口上,压套与井口接头由键固定,压帽与井口接头螺纹连接,在压帽和压套之间开有相连通的孔,孔中设有弹簧,弹簧顶住销子和锁芯。
本实用新型具有结构简单、防盗性能好、抗破坏能力强等优点。
图1:采油井口防盗装置结构示意图;
下面结合附图对本实用新型作进一步描述:
采油井口防盗装置由井口1、井口接头2、压帽3、键4、压套5、抽油杆6、钥匙7、锁芯8、销子9、弹簧10、盘根11组成,如图1所示,井口接头2焊接或粘接在井口1上,压套5将盘根11压在井口1与抽油杆6的环形空间内,盘根11起密封作用,压套5通过键4与井口接头2固定,键4阻止了压套5相对井口接头2转动,压帽3盖在压套5上面并与井口接头2螺纹连接,在压帽3和压套5之间开有相连通的孔,孔中设有弹簧10,弹簧10顶住销子9和锁芯8,销子9在压帽3和压套5之间,限制了压帽3的转动,钥匙7前端长度等于锁芯8下平面到压套5上平面的距离。
更换盘根时,将钥匙7旋入锁芯8内,向下压锁芯8,使锁芯8下平面与压套5的上平面平齐,销子9失去作用,即可拧下压帽3更换盘根11或拧紧压帽3,为了使防盗效果更好,本实用新型可开多个孔,设置不同的锁芯8和钥匙7,只有当几把钥匙共同使用才能将压帽3打开。
