Description

A kind of Safety well cover

Technical field

The utility model relates to a kind of well lid, particularly relates to a kind of Safety well cover.

Background technology

Well lid is for covering the fender of deep-well on road, is used for preventing that people or thing from falling down.Well lid generally is divided into circular and square, and aspect the road administration in urban district, the general circle that adopts, because circular well lid is difficult for tilting, can protect the safety of pedestrian and vehicle preferably.Use round manhole cover, mainly to consider that circular well lid is all the same by every diameter length in its center of circle, if when well lid has been rolled by the vehicle of process like this, because anyway rolled, its diameter all can be slightly wider than following well head, and well lid can not drop in well head and go.

But when rainy day, the water flowed in Deep Underground is on the increase and the well lid lid can be washed away, and uncovered deep-well mouth is passing pedestrian and vehicle, causes great potential safety hazard, for people's safety has been brought great threat.

The utility model content

The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of Safety well cover is provided.This Safety well cover can effectively avoid people or wheel to fall into the danger of well head after the well lid body is washed away, has good safety effect, has wide prospect of the application on urban road.

For achieving the above object, the technical solution adopted in the utility model is: a kind of Safety well cover is characterized in that: comprise well cover cycle, well lid body and be arranged on the safety shield in well cover cycle, described safety shield is arranged on the below of well lid body; Described safety shield comprises the guard ring be connected with the well lid body with well cover cycle, and is arranged in guard ring and the bearing net for after breaking away from guard ring at the well lid body, supplying people and Che to pass through.

Above-mentioned a kind of Safety well cover is characterized in that: convex is presented at the middle part of described bearing net.

Above-mentioned a kind of Safety well cover is characterized in that: the middle part of described bearing net is in a concave shape.

Above-mentioned a kind of Safety well cover is characterized in that: the bottom surface of described well lid body is provided with the support column connected with bearing net, and the edge of described support column and well lid body is by a plurality of reinforcement link of boards.

Above-mentioned a kind of Safety well cover is characterized in that: the mesh of described bearing net is circle or polygon.

Above-mentioned a kind of Safety well cover is characterized in that: described guard ring comprises the annular connecting plate that stretches into the sheath in well cover cycle and be positioned at the sheath upper end, and described annular connecting plate is arranged on well cover cycle inwall extension board.

Above-mentioned a kind of Safety well cover is characterized in that: described bearing net is formed from steel.

The utility model compared with prior art has the following advantages:

1, of the present utility model simple in structure, rationally novel in design, be easy to install.

2, the utility model is by arranging safety shield; when rainy, after the water in the inflow Deep Underground is on the increase the well lid body is washed away, now bearing net can effectively protect passing people can not slip and fall in well; simultaneously, also can make vehicle roll bearing net and pass through well head.

3, the utility model is designed to present convex by the middle part by bearing net, can strengthen like this weight capacity of bearing net, can pass through for the large-tonnage load-carrying vehicle.

4, the utility model is designed to concave shape by the middle part by bearing net, and connect with well lid body bottom supporting post, when usually using, strengthened the support force to the well lid body, and, after the well lid body breaks away from, the bearing net that middle part is concave shape can make vehicle safety pass through.

5, of the present utility modelly realize that cost is low, result of use is good, is convenient to promote the use of.

In sum, the utility model is simple in structure, rationally novel in design; functional reliability is high, and long service life can be after the disengaging of well lid body be washed away; effectively avoided people or wheel to fall into the danger of well head, effectively protected people's safety, be convenient to promote the use of.

Below by drawings and Examples, the technical solution of the utility model is described in further detail.

The specific embodiment

Embodiment 1

A kind of Safety well cover as shown in Figure 1 comprises well cover cycle 1, well lid body 4 and is arranged on the safety shield in well cover cycle 1 that described safety shield is arranged on the below of well lid body 4; Described safety shield comprises the guard ring 2 be connected with well lid body 4 with well cover cycle 1, and is arranged in guard ring 2 and for break away from the rear bearing net 3 passed through for people and Che of guard rings 2 at well lid body 4.

In the present embodiment, by safety shield is set, when rainy, after water in the inflow Deep Underground is on the increase well lid body 4 is washed away, now bearing net 3 can effectively protect passing people can not slip and fall in well, simultaneously, also can make vehicle roll bearing net 3 and pass through well head, because bearing net 3 is net structure, the well water constantly gushed in Deep Underground can not wash away bearing net 3 by mesh, this Safety well cover can be after the well lid body breaks away from, effectively avoided people or wheel to fall into the danger of well head, there is good safety effect, there is wide prospect of the application on urban road.

As shown in Figure 2, convex is presented at the middle part of described bearing net 3, can strengthen like this weight capacity of bearing net 3, can pass through for the large-tonnage load-carrying vehicle.Described bearing net 3 is formed from steel, and has further strengthened the weight capacity of bearing net 3.
