Novel safety manhole cover capable of preventing jacking and preventing shifting
The invention discloses a novel safety manhole cover capable of preventing jacking and preventing shifting. The novel safety manhole cover comprises a manhole cover body, a well base, a jacking preventing pressure relief device, a pin and a lock, wherein the manhole cover body is a disc-shaped manhole cover, the manhole cover body is arranged at the upper end of the well base, one end of the manhole cover body is hinged to the well base through the pin, the jacking preventing pressure relief device is arranged at the center of the manhole cover body, the jacking preventing pressure relief device is slidably connected with the manhole cover body, and the lock capable of being matched with the well base is arranged at the end, away from the pin, of the lower end surface of the manhole coverbody. According to the novel safety manhole cover capable of preventing jacking and preventing shifting, the jacking preventing pressure relief device is arranged at the center of the manhole cover, the pressure can be automatically relieved when the pressure in a well is tool large, the manhole cover is prevented from being jacked, the safety is improved, and the anti-theft performance of the manhole cover can be improved through the arrangement of the lock.
本发明公开了一种防顶起防移位新型安全窨井盖，包括井盖本体、井座、防顶起泄压装置、销轴、锁具，所述的井盖本体为圆盘状井盖，所述的井盖本体设于井座上端，所述的井盖本体一端通过销轴与井座铰接，所述的井盖本体中心设有防顶起泄压装置，所述的防顶起泄压装置与井盖本体滑动连接，所述的井盖本体下端面远离销轴的一端设有可以与井座配合的锁具，本发明通过将井盖中央设置防顶起泄压装置，能够在井内压力过大时自动泄压，防止井盖被顶起，提高安全性，通过设置锁具，可以提高井盖的防盗性能。
