Description

新型的电缆防爆盒 技术领域
本发明涉及电缆防爆盒技术领域，具体为新型的电缆防爆盒。
背景技术
电缆铺设好后，为了使其成为一个连续的线路，各段线必须连接为一个整体，这些连接点就称为电缆接头。由于现在大部分电缆均埋于地下，工作环境差，电缆接头在长期使用中容易因老化而产生打火、短路甚至发生爆炸，造成经济的重大损失甚至威胁到人身生命安全。由于目前我国电缆隧道数量有限，每个电缆隧道内的电缆数量较多，当一根电缆起火爆炸后，必将点燃其他电缆，引发二次爆炸，致使电缆隧道内电缆损毁。为了防止电缆接头处发生起火后引发二次事故，电缆接头处均采用防爆盒。为了防止电缆接头处发生起火后不断燃烧引起爆炸，需要保证防爆盒的密封性能，这样当起火后，由于氧气量有限而无法持续燃烧，可尽量避免爆炸发生。
目前的电缆防爆盒大多为两个壳体通过卡扣连接，但该电缆防爆盒的密封效果较差，容易影响电缆防爆盒的防爆效果，另外电缆接头在电缆防爆盒内稳定性较差，容易造成电缆接头松动，同时造成线路中断，并影响电缆工作的稳定可靠性。

请参阅图1-6，新型的电缆防爆盒，包括电缆防爆盒主体1，电缆防爆盒主体1的上表面开设有安装孔，电缆防爆盒主体1的上表面固定连接有限位框2，限位框2的内壁活动连接有弧形盖板3，弧形盖板3的侧壁固定连接有弧形卡片4，电缆防爆盒主体1的外壁固定连接有多个与弧形卡片4相配合的限位块5，多个弧形卡片4的外壁均固定连接有拉环6，弧形盖板3的上表面开设有固定通孔，且固定通孔的孔壁固定连接有防爆机构7，电缆防爆盒主体1的内壁固定连接有两个对称分布的支撑机构8，弧形盖板3的下表面固定连接有灭火机构9，电缆防爆盒主体1的两端均固定连接有锥形橡胶套10，锥形橡胶套10的外壁固定连接有多个橡胶环11，多个橡胶环11的内壁共同连接有钢丝绳12，弧形盖板3的内壁边缘处固定连接有矩形密封环13，限位框2的内壁固定连接有橡胶密封垫14。
防爆机构7包括圆筒71，圆筒71的上表面开设有连接通孔，且连接通孔的孔壁活动连接有移动杆72，移动杆72的底端固定套接有橡胶塞73，橡胶塞73的外壁与圆筒71的内壁活动连接，移动杆72的顶端固定连接有挡块74，移动杆72的杆壁活动套接有弹簧75，弹簧75的两端分别与圆筒71的上表面和挡块74的下表面固定连接，圆筒71的外壁开设有两个对称分布的排气孔76，弧形盖板3的上表面固定连接有挡罩77，挡罩77的内壁固定连接有橡胶球78，挡块74的上表面固定连接有刺针79。
支撑机构8包括与电缆防爆盒主体1内壁固定连接的支撑板81，支撑板81的上表面开设有两个通孔，且两个通孔的孔壁共同活动连接有U形杆82，两个U形杆82的杆壁共同固定连接有连接杆83，两个U形杆82的两端外壁均固定连接有楔形块84，电缆防爆盒主体1的内壁固定连接有支撑块85，支撑块85靠近U形杆82的一侧固定连接有多个楔形卡块86，两个U形杆82的杆壁均固定连接有橡胶压块87，该机构使电缆防爆盒具有电缆固定功能，提高电缆在电缆防爆盒内部的稳定性，并能够避免发生电缆接头松散而造成电路中断的情况，提高电缆防爆盒内电缆工作的稳定可靠性。
灭火机构9包括与弧形盖板3内壁固定连接的橡胶袋91和破碎刀片92，橡胶袋91内填充有灭火干粉93，破碎刀片92位于橡胶袋91的内部， 橡胶袋91被破碎刀片92刺破，此时橡胶袋91内灭火干粉93喷洒在电缆接头处，使接头处隔绝氧气，避免起火发生爆炸。
电缆防爆盒主体1的外壁开设有矩形通孔，且矩形通孔的孔壁固定连接有散热片15，散热片15能够提高电缆防爆盒的散热效果。
橡胶球78的内部填充有彩色涂料，橡胶球78内彩色涂料流出提醒工作人员该电缆防爆盒内电缆接头出现故障，以便工作人员能够快速抢修。
限位块5的侧壁开设有弧形卡片4侧端相配合的凹槽16，凹槽16能够提高弧形卡片4与限位块5连接的稳定可靠性。
弧形盖板3的上表面固定连接有弧形把手17，弧形把手17能够方便推动弧形盖板3与限位框2连接。
综上所述，该新型的电缆防爆盒，当需要把电缆防爆盒安装在电缆接头处时，首先把两端电缆穿过电缆防爆盒主体1两端，并通过钢丝绳12箍筋锥形接线套10，通过锥形橡胶套10对电缆防爆盒主体1两端密封处理，之后把两个电缆头穿过支撑板81和U形杆82，接着通过连接杆83按压U形杆82，U形杆82下移的过程中，橡胶压块87挤压电缆表面，同时楔形块84下移会在楔形卡块86的限位下达到固定电缆的目的，接着再对两个电缆进行连接，避免电缆在电缆防爆盒主体1晃动而造成电缆接头松动，并保障电缆能够正常工作，该机构使电缆防爆盒具有电缆固定功能，提高电缆在电缆防爆盒内部的稳定性，并能够避免发生电缆接头松散而造成电路中断的情况，提高电缆防爆盒内电缆工作的稳定可靠性，接着通过矩形密封环13和橡胶密封垫14提高弧形盖板3与电缆防爆盒主体1连接的密封性，进而提高电缆防爆盒的密封性，同时通过弧形卡片4和限位块5能够提高电缆防爆盒安装的便捷性，在电缆接头出现异常使电缆防爆盒内温度升高要发生爆炸时，首先温度升高使电缆防爆盒内空气膨胀，空气膨胀使橡胶袋91向上形变，接着橡胶袋91被破碎刀片92刺破，此时橡胶袋91内灭火干粉93喷洒在电缆接头处，使接头处隔绝氧气，避免起火发生爆炸，同时电缆防爆盒内气体会挤压橡胶塞73，橡胶塞73在弹簧75的压力下继续向上移动，最终电缆防爆盒主体1内空气会通过排气孔76排出，以便降低电缆防爆盒主体1内压力，防止电缆防爆盒爆炸，以及橡胶塞73向上移动时，挡块74随着移动杆72上移，且挡块74上的 刺针79向上移动刺破橡胶球78，橡胶球78内彩色涂料流出提醒工作人员该电缆防爆盒内电缆接头出现故障，以便工作人员能够快速抢修，该机构能够有效提高电缆防爆盒的密封性，通过防爆机构和灭火机构提高电缆防爆盒的防爆效果，同时使电缆防爆盒具有灭火功能，另外电缆防爆盒安装使用过程简便，能够提高电缆防爆盒安装的效率。
