Problems solved by technology

Due to the continuous rolling of passing vehicles, the single-layer manhole cover is easy to warp or even damaged, which poses a safety hazard
The existing double-layer manhole cover has a complex structure, troublesome loading and unloading, and high cost. During the rolling process of large-scale trucks, it is easy to generate resonance and loosen, and it is easy to be washed away by floods.
Therefore, people often use protective mesh covers to replace the above-mentioned manhole covers, but the installation procedures of protective mesh covers are cumbersome, and most of them are fixed covers, which require special tools to unload them.

Embodiment Construction

[0014] The accompanying drawings disclose the specific structure of the present invention without limitation, and the present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 , 2 As shown, the anti-washout safety well cover includes a well base 1 and a circular outer well cover 2 installed on the well base 1. Because the circular well cover is not easy to tilt, it can better protect the safety of pedestrians and vehicles; Below the outer well cover 2, an inner well cover 3 is also provided, and the periphery of the inner well cover 3 is set as a sector in a fan-shaped structure, and the inner well cover 3 and the outer well cover 2 are fixedly connected by a rubber layer 4; There is a groove 5 matched with the fan-shaped structure of the inner well cover 3. The inner manhole cover 3 has three sectors, which are equally distributed around the circumference of the inner manhole cover 3. It is the most stable pri...

Abstract

The invention discloses a washing-off-proof safety well lid which comprises a well seat and a round outer well lid installed on the well seat. An inner well lid is further arranged under the outer well lid, and fan blades of a sector structure are arranged on the periphery of the inner well lid, the inner well lid and the outer well lid are fixedly connected through a rubber layer, and a groove matched with the sector structure of the inner well lid is formed in the inner ring of the well seat. The well lid is simple in structure, convenient to operate, good in pressure resistance and shock resistance, good in stability and safe and reliable.

Description

technical field [0001] The invention relates to a well cover, in particular to an anti-washout type safety well cover. Background technique [0002] Manhole cover is used to cover the defenses on roads or oil wells to prevent people or objects from falling. It is one of the supporting facilities widely used in municipal and industrial applications. At present, the structure of most well covers includes a well base and a single-layer / double-layer well cover plate embedded with the well base. Due to the continuous rolling of passing vehicles, the single-layer manhole cover is easy to warp or even damaged, which poses a safety hazard. The existing double-layer manhole cover has a complex structure, troublesome loading and unloading, and high cost. During the rolling process of large-scale trucks, it is easy to generate resonance and loosen, and it is easy to be washed away by floods. Therefore, people often use protective mesh covers to replace the above-mentioned well covers...
