Inspection well cover capable of being detonated actively
The invention discloses an inspection well cover capable of being detonated actively. An existing system for avoiding gas explosion in an inspection well is complex and high in cost. According to the inspection well cover capable of being detonated actively, a solar cell panel is arranged on the top face of a well lid body, a working cavity is formed in the lower portion of the well lid body, and a charging controller, a storage battery and an electric spark generating device are arranged in the working cavity; the solar cell panel is connected with the storage battery through the charging controller to charge the storage battery; the electric spark generating device comprises a timing switch, an igniter and an ignition coil; two input ends of the timing switch are connected with positive and negative electrodes of the storage battery respectively, and output ends are connected with a power supply end and a grounding end of the igniter respectively; and the power end and the output end of the igniter are connected with two ends of the primary side of the ignition coil, and two ends of the secondary side of the ignition coil are connected with spray points arranged outside the working cavity. The inspection well cover capable of being detonated actively is relatively simple in structure, a method of initiative detonation of low-concentration methane is adopted, and fierce detonation of high-concentration methane in the inspection well is effectively avoided.
本发明公开了一种主动引爆的窨井盖。现有的避免窨井内气体爆炸的系统比较复杂、成本比较高。本发明的井盖本体顶面设置有太阳能电池板，井盖本体的下部设置有工作腔，工作腔内设置有充电控制器、蓄电池、电火花发生装置。太阳能电池板通过充电控制器与蓄电池连接，为蓄电池充电。电火花发生装置包括定时开关、点火器和点火线圈。定时开关的两个输入端分别接蓄电池的正、负极，输出端分别接点火器的电源端和接地端。点火器的电源端和输出端接点火线圈原边的两端，点火线圈副边的两端连接放电针，放电针设置在工作腔外。本发明提出的主动引爆窨井盖结构相对简单，采用主动引爆低浓度甲烷的办法，有效避免窨井内较高浓度甲烷的激烈爆燃。
