Description

Technical Field

[0001] This utility model relates to the technical field of manhole protection devices, and in particular to a safety anti-fall device for manholes in pipeline networks. Background Technology

[0002] Urban construction involves many underground pipelines, such as sewers, underground gas pipelines, water supply pipelines, power pipelines, communication pipelines, and defense pipelines. These pipelines have an outlet to the ground at intervals. This section from the pipeline to the ground is called a manhole. The manhole opening is usually flush with the ground. The cover used to cover the manhole is called a manhole cover or well cover. The manhole cover is a protective device to prevent people or objects from falling into the manhole. It is used to cover the manhole opening and play a protective role. The prior art announcement number CN217870627U discloses a manhole fall prevention protection device, including a manhole cover frame. Five sets of reinforcing frames are installed at the bottom of the manhole cover frame, and a fixed column is installed at the center of the bottom of the manhole cover frame. A reinforcing bracket is provided on the outside of the fixed column. A reinforcing rib is connected between adjacent reinforcing frames, and a reinforcing rib is connected between the outer edge of the reinforcing frame and the bottom edge of the manhole cover frame. Several ribs are installed on the inner side of the reinforcing frame. Several pry holes are equidistantly opened at the top edge of the manhole cover frame. Both the bottom of the manhole cover frame and the bottom of the reinforcing frame are provided with extended sides. The reinforcing rib is located between the extended side of the bottom of the manhole cover frame and the extended side of the bottom of the reinforcing frame. However, when it is necessary to go down into the well, the safety net must be removed first, and then ropes or ladders must be carried into the well. After the work is completed and the person comes out of the well, the safety net must be reinstalled at the wellhead. The whole process is complicated, time-consuming and labor-intensive. Utility Model Content
