Abstract

The utility model relates to a three-prevention well cover, particularly a well cover facility with a novel structure. A well cover of a city well bore at present is very easy to lose to cause property loss and person harm. Both ends of a well cover sheet (4) and a well cover seat (3) of a novel well cover provided by the utility model are respectively provided with ear part structures, wherein a hinge structure is formed on one end. In this way, after the novel well cover is laid, the well cover sheet (4) is not easy to take down from the well cover seat (3). A lockset (8) is additionally arranged on the other end, and the safe degree of the novel well cover is enhanced. In addition, a sealing rubber strip (13) can be arranged on the pressing position of the well cover sheet (4) and the well cover seat (3) in order to improve the waterproof performance of a well bore cover. The well wall (10) of the well cover seat can be lengthened in order to satisfy the cold protection requirements of a well bore in a northern area, and a heat insulation benzene plate (12) is arranged on the well wall.

Description

Tri-proof well cover

Technical field

The utility model relates to a kind of novel pit shaft lid structure, is mainly used on the various urban operating mechanism pit shafts.

Background technology

In all kinds of urban operating mechanisms in city, there is a large amount of pit shafts, be used to arrange water supply, air feed, power supply, communication and detection maintenance thereof, the pit shaft lid is made up of well lid sheet and manhole cover base, generally make by cast iron, at present the problem that exists is losing in a large number of well lid sheet, has lost the property loss that the pit shaft of well lid sheet can cause personnel to injure again.Some pit shaft in addition, for example water meter measurement well and telecommunication relaying well need again to prevent that sleet from infiltrating, and the winter protection requirement is arranged again winter, existing well lid structure all can not effectively address these problems.Someone once attempted making well lid with nonmetals, but because of not success of insufficient strength.Some important pit shaft is that waterproof is raised manhole cover base now, influences the smooth and attractive in appearance of road.

Summary of the invention

Provide a kind of Tri-proof well cover, existing in prior technology is easily stolen to overcome, the defective of waterproof, cold protective performance difference order of the present utility model.The utility model is made up of well lid sheet 4 and manhole cover base 3, Fig. 1 is its vertical view, Fig. 2 is Figure 1A-A direction sectional view, well lid sheet 4 has two ears 1,7, manhole cover base 3 has two ears 2,5, an ear 7 of well lid sheet 4 is equipped with horizontal eyelet, corresponding that ear 5 of manhole cover base 4 also is equipped with eyelet, bearing pin 6 is through in ear's eyelet of well lid sheet 4 and manhole cover base 3 and makes well lid sheet 4 and manhole cover base 3 form a hinge structure, because manhole cover base and road surfacing are integral, so bearing pin 6 can't take out after manhole cover base 3 is laid, just prevent from also that well lid sheet 4 and manhole cover base 3 break away to lose.In the ear 2 of the other end lockset 8 is housed in addition; be processed with a stepped not isometrical concentric axis hole in well lid sheet ear 1; the recessed frame shape of manhole cover base ear 2 is also corresponding to be equipped with one and not to lock the footpath concentric holes; the lockhole of lockset 8 part and dead bolt partly are assembled in the eyelet place of ear 1 and 2 with screw 9; like this after the well lid laying installation; utilize private key to insert in the lockset eyelet and twist 90 °, the dead bolt of bottom can pin the well lid sheet, and the safeguard protection degree of well lid is improved.For improving the water-tight performance of well lid, can establish sealing joint strip 13 in pressing place of well lid 3 and well lid sheet 4, can prevent that like this rainwater from infiltrating in the well.For improving the cold protective performance of pit shaft, the borehole wall 10 of manhole cover base 3 can be extended, and make the shoulder shape in the lower end, so that place insulation benzene plate 12, the benzene plate is equipped with handle 11, is convenient to the carrying operation.The utlity model has good antitheft, waterproof, cold protective performance; be applied in all kinds of urban operating mechanism wells; will reduce the Loss Rate of well lid sheet greatly, have very big economic benefit and social benefit, the protection of excellent waterproof and winter protection also can be provided some pit shafts simultaneously.
