Abstract

A protective net for a manhole cover relates to a protective net. The protective net adopts the technical proposal that the protective net for the manhole cover comprises a protective net and fixed rings; the protective net is formed by weaving a plurality of cords; the periphery of the protective net is connected with the fixed rings; the size of each fixed ring is matched with the inner wall of a manhole; and the fixed rings are suspended at the periphery of the inner wall of a manhole mouth under the manhole cover. The protective net for the manhole cover has the advantages of simple and reasonable structure, and convenient operation; only the inner wall of the manhole mouth under the manhole cover is connected with the fixed rings through hooks; the weight and the impact force of a person can be effectively supported when the person drops into the manhole carelessly, thereby avoiding the fortuitous casualty of the people caused by the loss and the damage of the catch basin cover.

Description

Inspection shaft lid protective screening

Technical field

The utility model relates to a kind of protective screening, is specially a kind of inspection shaft lid protective screening that is used for draining, underground cable access hole.

Background technology

Along with economy, fast development of society, various inspection shafts are more and more on the road, comprise the maintenance inspection shaft of drainage system, electrical cable, and the inspection shaft of equipment such as communication network and coal gas.Inspection shaft lid commonly used is made of Moveable lid body and the lining that is fixed on the road surface, and Moveable lid body can be opened or close, and identical smooth with the road surface, guarantees the unimpeded of pedestrian, vehicle.This type of inspection shaft lid is generally made by cast iron, have the strong characteristics of anti-impact force, but cast iron itself has higher economic value, often becomes the object that the undesirable steals; More particularly be positioned at the inspection shaft lid of remote position, often stolen and be difficult in time redistribute installation, constitute dangerous pedestrian and driving.In addition, because inspection shaft lid quality problems are damaged by pressure by vehicle, in time do not repair or change; Or open the draining of inspection shaft lid and forget and cover back; These do not cover or uncap that to forget that situation about resetting again all constitutes pedestrian or driving dangerous, often have vehicle to be absorbed in the accident that inspection shaft or pedestrian fall in the well and take place, and have become urban construction and have been badly in need of the significant problem that solves.

The utility model content

Technical problem to be solved in the utility model is to overcome above-mentioned the deficiencies in the prior art; a kind of inspection shaft simple in structure, easy to use lid protector is provided; this device has the advantages that to protect pedestrian, traffic safety to greatest extent, can be widely used in all kinds of inspection shafts and cover.

The technical solution adopted in the utility model is: inspection shaft lid protective screening comprises protecting wire net, retainer plate; Protecting wire net is formed by the braiding of some cotton ropes, be connected on the retainer plate around the protecting wire net, the inwall fit of the size of retainer plate and inspection shaft, retainer plate be suspended on inspection shaft lid bottom inspection shaft mouth inwall around.

Described retainer plate adopts 0.6-1.5 centimetre hawser to make, so that this rope has certain rigidity.

There is a center ring at the center of described protecting wire net, and protecting wire net is woven into by some cotton ropes between center ring and the retainer plate.

Described protecting wire net is a fishing net shape structure, and the aperture of mesh is 5-10CM.

After described retainer plate passed the mesh at protective screening edge successively by hawser, fag end was fixedlyed connected formation with tail of rope.

The hook that is provided with on described retainer plate and the inspection shaft mouth inwall articulates, and covers on the following inspection shaft mouth so that protective screening is suspended on inspection shaft.

The inspection shaft lid protective screening that the utility model provides, simple and reasonable, easy to use, only need to cover on the following inspection shaft mouth inwall to articulate to get final product by hook and retainer plate at inspection shaft, can be personnel just in case support the person's of falling into weight and impact force effectively when falling into inspection shaft accidentally, avoided the personnel's fortuitous casualty that causes because of inspection shaft losing of cover or damage.In addition, the retainer plate of this inspection shaft lid protective screening constitutes by linking before and after the rope of certain intensity, and manufacturing process is simple, and can not be out of shape because of long-term the use, closely is connected on the inspection shaft lid inwall, has improved application life, has vast market prospect.

Description of drawings

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the structure mounting structure schematic diagram of inspection shaft lid protective screening.

Among the figure: 1-protecting wire net, 2-retainer plate, 3-center ring, 4-hook, 5-inspection shaft, 6-inspection shaft lid.

The specific embodiment

The utility model is described in further detail by following examples.

As shown in the figure: this inspection shaft lid protective screening comprises protecting wire net 1 and retainer plate 2; Described protecting wire net 1 can all be woven into the fishing net shape with some cotton ropes, and the aperture of mesh is 5-10CM; The mesh that a certain size is set can prevent effectively that not only the pedestrian from falling in the inspection shaft 5 accidentally when uncovered, also do not influence daily blowdown, draining processing; Be connected on the retainer plate 2 around the protecting wire net, the inwall fit of the size of retainer plate 2 and inspection shaft 5, by the hook that is provided with on the inspection shaft mouth inwall, protective screening is suspended on inspection shaft covers (also a center ring 3 can be set at the center of protecting wire net 1, protecting wire net 1 is formed by some cotton rope braidings between center ring 3 and the retainer plate 2) on the following inspection shaft mouth.Retainer plate 2 adopts 0.6-1.5 centimetre hawser to make, thereby has certain rigidity, can be close to the inwall of inspection shaft, makes the slit reduce to minimum, has improved safety and the reliability used; When the pedestrian falls into inspection shaft accidentally, can support the person's of falling into weight and impact force effectively, avoid losing or damaging the personnel's fortuitous casualty that causes because of inspection shaft lid 6.

Hook 4 as shown in Figure 2 adopts usually directly and is packing into after the punching on the inspection shaft inwall, and hook is 10-30CM apart from the optimum position of inspection shaft mouth, and the distance between the hook is about 20-40CM in twos; The hook buyable.

Protecting wire net 1 in the utility model can make each cotton rope all can share relatively little power stressed being distributed on all cotton ropes of protecting wire net when using, and has avoided causing because of local pressure is excessive the breakage of protective screening.
