Novel manhole cover for municipal engineering
The invention discloses a novel manhole cover for municipal engineering. The novel manhole cover for municipal engineering structurally comprises a fixing seat, a fixing hole and a manhole cover body.The manhole cover body comprises a movable shaft, a drainage groove, a through hole, a clamping block and a stirring block. The stirring block comprises a connecting rod, a limiting block, a baffle and a rolling block. The rolling block comprises a main column, an outer roller body, a fixing rod, a return spring and a telescopic block. The telescopic block comprises a telescopic body, a supporting seat, a rubber pad and grooves. According to the novel manhole cover for municipal engineering, the baffle is impacted by rainwater, the baffle drives the connecting rod to rotate, and the rolling block embedded right in the middle of the connecting rod also rotates along with the baffle. The telescopic block is made of rubber, so that friction force can be increased when the telescopic block isin contact with a plastic bag. The multiple triangular grooves are transversely formed in the upper end face of the rubber pad, the plastic bag can be adsorbed in the grooves, and friction force between the rubber pad and the plastic bag is increased. Therefore, the plastic bag attached to the manhole cover is guided to the lower end of the manhole cover, and the situation that the plastic bag isattached to the manhole cover to cause blockage is avoided.
本发明公开了一种新型市政工程用井盖，其结构包括固定座、固定孔、井盖，井盖包括活动轴、排水槽、通孔、卡合块、搅动块，搅动块包括连接杆、限位块、挡板、滚动块，滚动块包括主柱、外辊体、固定杆、复位弹簧、伸缩块，伸缩块包括伸缩体、支撑座、橡胶垫、凹槽，本发明通过雨水撞击到挡板，使得与挡板带动连接杆旋转，让嵌固在连接杆正中间的滚动块也跟随旋转，通过伸缩块为橡胶材质，让伸缩块与塑料袋接触时可以增加摩擦力，将多个三角形状的凹槽横向排列在橡胶垫的上端面，让塑料袋可以吸附在凹槽中，增加橡胶垫与塑料袋之间的摩擦力，从而将附在井盖上的塑料袋导向井盖的下端，避免塑料袋附在井盖上造成堵塞的情况。
