Safety manhole cover with long service life
The invention relates to a safety manhole cover with long service life. The safety manhole cover with the long service life comprises a mounting pipe, a manhole cover body and two through holes, and further comprises a buffer mechanism and an exhaust mechanism. The buffer mechanism comprises a supporting ring, a sliding rod, two first springs, two sliding sleeves, two transmission rods and two positioning assemblies, the exhaust mechanism comprises a sealed cylinder, a piston block, a sealed sleeve, a supporting rod, a second spring, a fixed rod, two vent holes, two covering plates, two gas pipes and two gas ejector pipes. The positioning assemblies comprise positioning grooves and positioning blocks. According to the safety manhole cover with the long service life, the probability of damage to the manhole cover body is reduced through buffer effect of the buffer mechanism on the manhole cover body, the service life of the manhole cover is prolonged, the combustible gas inside the manhole cover can be discharged through the exhaust mechanism, the concentration of the combustible gas inside the manhole cover is reduced, and the safety of the manhole cover is improved.
本发明涉及一种使用寿命长的安全型窨井盖，包括安装管、井盖和两个贯穿孔，还包括缓冲机构和排气机构，所述缓冲机构包括支撑环、滑杆、两个第一弹簧、两个滑动套管、两个传动杆和两个定位组件，所述排气机构包括密封缸、活塞块、密封套管、支撑杆、第二弹簧、固定杆、两个通气孔、两个盖板、两个输气管和两个喷气管，所述定位组件包括定位槽和定位块，该使用寿命长的安全型窨井盖中，通过缓冲机构对井盖的缓冲作用，降低了井盖发生损坏的几率，延长了窨井盖的使用寿命，通过排气机构可以将窨井盖内部的可燃气体排出，降低了窨井盖内部可燃气体的浓度，提高了窨井盖的安全性。
