具体实施方式
具体实施例如下：
请参照图1所示，一种高强度减震器，它包括上接头1、上连接套2、卡块3、连接套4、弹簧5、下连接套6和下接头7；所述连接套2套置在上接头1上；上连接套2、连接套4、下连接套6和下接头7依次螺纹连接组成外壳组件；卡块3安装在上接头1的槽内组成芯轴组件，外壳组件和芯轴组件间为用于放置弹簧5的弹簧环形空腔102；卡块3的上端面与上连接套2的下端面贴合来实现外壳组件和芯轴组件相连接；所述上接头1和下接头7的两端扣型可调整连接以达到拆卸内部电缆配合组件后其内部实现通孔。所述上接头1、上连接套2、下连接套6和下接头7均设有放置密封件的密封件凹槽。所述连接套2上有多个阻尼孔，上连接套2和连接套4、下连接套6和下接头7以及下连接套6和上接头1之间均为密封连接来实现弹簧环形空腔102和井内液体仅通过上连接套2的阻尼孔连通。所述卡块3与连接套4之间设有环形间隙以使弹簧环形空腔102通过上连接套2的阻尼孔与井内液体串通。所述上接头1与上连接套2之间采用键连接方式来传递扭矩。所述上接头1内安装有防转插座8、电缆9、插座12和插针组件14；电缆9两端分别与防转插座8、插座12连接，插座12和插针组件14依次连接到下接头7，插座12穿过上接头1内孔与插针组件14连接。
本实用新型的具体实施方式如下：如图1所示，本实用新型高强度减震器包括上接头1、上连接套2、卡块3、连接套4、弹簧5、下连接套6、下接头7、防转插座8、电缆9、密封件10、密封件11、插座12、绝缘套13、插针组件14、穿电缆内腔101、弹簧环形空腔102。其中上连接套2、连接套4、下连接套6和下接头7依次螺纹连接组成外壳组件；卡块3安装在上接头1的槽内组成芯轴组件，两组件间为弹簧环形空腔102用于放置弹簧5，卡块3的上端面与上连接套2的下端面贴合、限位，实现两组件连接。上接头1、上连接套2、下连接套6、下接头7均有密封件凹槽用于放置密封件10、密封件11和密封件15。上连接套2和连接套4、下连接套6和下接头7、下连接套6和上接头1分别配合密封实现弹簧环形空腔102和井内流体仅通过上连接套2的阻尼孔连通，以及穿电缆内腔101密封。上接头1与上连接套(2)之间采用键连接方式可传递扭矩；另外，卡块3与连接套4之间有环形间隙使弹簧环形空腔102通过上连接套2的阻尼孔与井内液体串通。插座12与插针组件14依次连接到下接头7，电缆9两端分别与防转插座8、插座12连接，插座12穿过上接头1内孔与插针组件14连接，防转插座8安装在上接头1内。
本实用新型高强度减震器的工作原理如下：首先在入井前，可根据作业情况，通过改变弹簧5种类、组合形式和改变上连接套2上阻尼孔数量和大小，可调节减震效果。当减震器连接在工具串中入井时，井内液体通过上连接套2上的阻尼孔和卡块3与连接套4之间的环形间隙注满弹簧环形空腔102。当减震器下部出现冲击时，下部工具传递冲击至下接头7，下接头7与连接的上连接套2、连接套4、下连接套6组成的外壳组件整体向上移动，压缩弹簧，吸收冲击力，实现机械减震；同时压缩弹簧环形空腔102内液体，液体通过卡块3与连接套4之间的环形间隙以及上连接套2上的阻尼孔流出，产生节流缓冲，实现液力减震，两种减震方式共同吸收冲击力，避免上部工具串受强冲击力。在向上冲击结束后，工具串整体回落，减震器受拉伸，弹簧环形空腔102体积增大，液体通过上连接套2上的阻尼孔以及卡块3与连接套4之间的环形间隙进入弹簧环形空腔102，产生节流缓冲，实现液力减震，避免工具串受强冲击力。当减震器上部出现冲击时，上部工具传递冲击至上接头1，上接头1与卡块3组成的芯轴组件整体向下移动，压缩弹簧，吸收冲击力，实现机械减震；同时，压缩弹簧环形空腔102内液体，液体通过卡块3与连接套4之间的环形间隙以及上连接套2上的阻尼孔流出，产生节流缓冲，实现液力减震，两种减震方式共同吸收冲击力，避免下部工具串受强冲击力。
以上所述仅是本实用新型的优选实施方式，本实用新型的保护范围并不仅局限于上述实施例，凡属于本实用新型思路下的技术方案均属于本实用新型的保护范围。应当指出，对于本技术领域的普通技术人员来说，在不脱离本实用新型原理前提下的若干改进和润饰，这些改进和润饰也应视为本实用新型的保护范围。
