Description

Technical Field

[0001] This utility model belongs to the field of urban drainage technology, specifically relating to a new type of sewage well cover anti-fall cage. Background Technology

[0002] A manhole cover fall arrestor is a safety device installed at the opening of a manhole to prevent pedestrians or vehicles from accidentally falling into a manhole that is open due to a missing, damaged, or improperly closed cover. This safety measure is typically made of metal mesh or other sturdy materials and designed to withstand a certain weight, ensuring temporary safety even when the cover is not in place. Installing fall arrestors can significantly reduce the risk of accidents, especially in busy urban areas.

[0003] Chinese Patent CN118958376A (publication date: November 15, 2024) discloses a fall-prevention cable wellhead, comprising: a well body divided into two sections, namely an upper wellhead and a lower wellhead, the upper wellhead having a larger diameter than the lower wellhead; a fixing ring fixed in the upper wellhead, the fixing ring having a limiting groove and a toothed ring on its inner ring side; and a limiting ring, the limiting ring having a lever on its inner ring side and multiple support legs fixed radially on its outer ring side, the support legs being inserted into the limiting groove. The lower end face of the limiting ring is provided with several support columns. All the support columns are arranged in a ring array at the lower part of the limiting ring. Each support column is equipped with a corresponding baffle. The baffle can rotate around the support column. The baffle has a semi-circular structure. The edge of the baffle is provided with an inner concave arc and an outer convex arc. The radii of the inner concave arc and the outer convex arc are equal. The outer convex arc is an arc edge with the hinge point as the center. This arc edge is divided into two segments. One segment is provided with outer convex teeth, which mesh with the toothed ring. The other segment slides into the inner concave arc on the adjacent baffle.

[0004] Chinese Patent CN221072727U (publication date: June 4, 2024) discloses a manhole anti-fall device, including a manhole body assembly and an anti-fall assembly. The manhole body assembly includes a manhole casing, an embedded plate, and a detection component. The embedded plate is fixed to the surface of the manhole casing, and the detection component is disposed inside the manhole casing. The anti-fall assembly includes a fixing ring, an anti-fall net, a snap-fit ​​block, a snap-fit ​​plate, and a limiting component. The fixing ring is disposed inside the manhole casing, the anti-fall net is fixed to the bottom of the fixing ring, and the snap-fit ​​block is fixed to one side of the fixing ring. The beneficial effects of this invention are: by setting up the anti-fall assembly, the anti-fall net can shield the inside of the manhole casing, preventing falls during manhole cover opening and improving pedestrian protection; by setting up the limiting component, the anti-fall net can be quickly connected and fixed, while facilitating disassembly by workers, reducing the complexity of the disassembly process and improving maintenance efficiency.

[0005] While traditional fall arresters have played a significant role in preventing pedestrians or vehicles from accidentally falling into sewage wells, they also have some drawbacks and limitations. Existing fall arresters have column- or cylindrical fixing devices at the bottom, which are bulky and inconvenient to install. Furthermore, they can only be installed and function properly after the well cover is missing. In addition, during heavy rains, typhoons, or other periods of high water flow, traditional well covers cannot effectively drain water, and may be pushed up and displaced, spilling debris from the well onto the road. Traditional fall arresters are also ineffective at night or in severe weather. Utility Model Content

[0006] To solve the above technical problems, this utility model provides a novel sewage well cover anti-fall cage, including a warning device, an anti-fall device, and a fixing device; the warning device is located above the anti-fall device and is bolted to the anti-fall device; the fixing device is located below the anti-fall device and is fixedly connected to the anti-fall device.

[0007] The fall arrestor includes an installation layer, a connecting layer, and a fixing layer; the connecting layer is located between the installation layer and the fixing layer and is fixedly connected to the installation layer and the fixing layer.

[0008] The mounting layer includes an upper waist ring, several support rods, and a fixing plate; the support rods are located inside the upper waist ring and are fixedly connected to it; the fixing plate is located above the support rods and is fixedly connected to them; the support rods are used to prevent the upper waist ring from being deformed by impact and to support the fixing plate, and the fixing plate is used to install warning devices.

[0009] The connecting layer includes several mid-waist rings and several connecting vertical rods; the connecting vertical rods are located inside the mid-waist rings and are fixedly connected to them. The connecting vertical rods are used to support and connect the installation layer and the fixing layer, and the mid-waist rings are used to reinforce the connecting vertical rods, ensuring that the water flow pressure is relieved while blocking garbage.

[0010] The fixing layer includes a lower outer waist ring, a lower inner waist ring, and several connecting crossbars; the lower inner waist ring and the connecting crossbars are located inside the lower outer waist ring; the connecting crossbars are located between the lower outer waist ring and the lower inner waist ring, and are fixedly connected to the lower outer waist ring and the lower inner waist ring; the length of the connecting crossbars is 15-20cm. The design of the lower inner waist ring and the lower outer waist ring can maintain structural stability while ensuring the relief of water flow pressure and preventing the fall arrestor cage from being washed away by the water flow.
