Description

Technical Field

[0001] This utility model relates to the field of urban roads, and specifically refers to a manhole anti-fall warning device. Background Technology

[0002] Manhole covers and frames are common infrastructure in urban roads and various public areas. The frames are housed within concrete manhole casings. However, with existing technology, damaged, lost, or displaced manhole covers can lead to pedestrians or vehicles accidentally falling into them, causing personal injury or property damage, especially at night or in poor visibility. Therefore, measures are needed to address this problem of damaged manhole covers causing pedestrians or vehicles to fall into manholes and suffer personal injury or property damage. Summary of the Invention

[0003] The purpose of this utility model is to overcome the defects of the prior art and provide a manhole anti-fall warning device to solve the problem that pedestrians or vehicles may accidentally fall into the manhole after the existing manhole cover is damaged or displaced, causing personal injury or property damage.

[0004] The technical solution to achieve the above objective is: a manhole anti-fall warning device, located below a manhole cover, the manhole cover being mounted on a manhole base, the warning device comprising:

[0005] A fall-prevention net is attached to the manhole base and located below the manhole cover, the fall-prevention net covering the interior space of the manhole base;

[0006] A rotatable warning light is mounted on the manhole base, positioned between the fall arrest net and the manhole cover. A return spring is provided at the rotatable connection of the warning light. The return spring applies a spring force to the warning light so that one end of the warning light abuts against the bottom surface of the manhole cover. After the manhole cover is removed, the spring force applied by the return spring to the warning light causes it to rotate until it is in contact with the inner wall of the manhole base and protrudes from the manhole base.

[0007] The further improvement of this utility model is that: multiple fixed hooks are connected to the wellhead of the well seat, and the anti-fall net is tied to the fixed hooks.

[0008] The further improvement of this utility model is that the end of the fixing hook near the fall protection net is in the shape of a hook.

[0009] A further improvement of this utility model is that the plurality of fixed hooks are spaced apart at the wellhead of the well base.

[0010] A further improvement of this utility model is that a fixed seat is installed on the inner wall of the wellhead of the well seat.

[0011] The further improvement of this utility model is that the fixing base is connected to the warning light, and the warning light is suspended by being connected to the fixing base.

[0012] The further improvement of this utility model is that the warning light is provided with a reflective strip for reflective warning.

[0013] A further improvement of this utility model is that the warning light is made of a flexible plastic device.

[0014] A further improvement of this utility model is that a well ring is installed in the groove of the well base.

[0015] A further improvement of this utility model is that a groove is provided on the side of the well ring near the well seat.

[0016] By utilizing the above technical solution, the technical effects achieved by this utility model compared to the prior art are as follows:

[0017] This utility model provides a manhole anti-fall warning device. By unfolding the anti-fall net and placing it at the manhole opening of the manhole seat, the entrance of the manhole seat is blocked. It can prevent people from falling when the manhole cover is missing or damaged, protect the lives of pedestrians, effectively prevent pedestrians or vehicles from falling into the manhole, and greatly reduce the risk of personal injury and property loss. Furthermore, the warning light is placed on top of the anti-fall net, which will not hinder the automatic pop-up of the warning light.

[0018] When the manhole is uncovered, the warning light will automatically pop up after being squeezed. The reflective strip on the warning light can reflect the light source, achieving the effect of early warning, reminding pedestrians to pay attention to safety, and reducing the probability of accidents.

[0019] By making the end of the fixing hook connected to the fall protection net into a hook shape, the fixing hook can be better connected to the fall protection net, making the connection effect of the fall protection net stronger. Attached Figure Description
