Abstract
The utility model discloses a well cover system, which is formed by welding both sides of a front vertical plate and lateral vertical plates, and then welding the lateral vertical plates and the back vertical plate, and is characterized in that after welding, upper edges are arranged on upper parts of the front vertical plate, the lateral vertical plates and the back vertical plate, and bottom sides are arranged on lower parts, and the combined structure is a well cover body. A cover board is connected with the back vertical plate through a hinge, the back vertical plate is provided with a vent hole and a static grounding hole, and hydraulic rods are symmetrically arranged on the cover board and the lateral vertical plates; after the cover board and the upper edges of the well cover body are buckled and pressed, they are in coincident connection. Fixing holes are arranged on the bottom side of the well cover body, and the fixing holes are connected with a well mouth through expansion bolts. The lateral vertical plates have inclination. The cover board is provided with a handle convenient for opening and a gate lock convenient for locking. The well cover system, provided by the utility model, is made by a full-aluminum plate, so that spark cannot be generated under any conditions, and the vices of combustion supporting, difficulty in deformation and the like can be overcome. The well cover system, provided by the utility model, has the advantages of simple structure, reasonable design, quick installation, light operation and the like.
Description
Technical field
The utility model relates to a kind of well lid system, particularly a kind of can waterproof and dustproof, fire prevention, antistatic, antitheft, on-deformable well lid system.
Background technology
At present, practical glass fibre reinforced plastic manhole covers, stainless steel well lid, plug-type well lid and the advanced composite material (ACM) oil-well cover etc. in ground such as each oil depot, petrol filling station.All can not satisfy the employee's of petrol filling station demand in its material of these well lids, performance, characteristic and application life etc.As: glass fiber reinforced plastic is perishable; Stainless steel is too thin; Plug-type too heaviness etc.
Summary of the invention
To the deficiency that above-mentioned technical problem exists, the purpose of the utility model is to provide a kind of well lid system.
The technical scheme of the utility model is following:
A kind of well lid system; Comprise the welding of front vertical plate (1) both sides and cant board (6); Cant board (6) welds with back vertical plate (7) again, it is characterized in that, the top after front vertical plate (1), cant board (6) and back vertical plate (7) welding is provided with upper edge (13); The bottom is provided with base (12), and the structure after the combination is referred to as the well lid main body like this.
Cover plate (2) connects back vertical plate (7) through hinge (5), and back vertical plate (7) is provided with air-vent (8) and electrostatic grounding hole (10), on cover plate (2) and cant board (6), is symmetrically arranged with hydraulic stem (11);
Cover plate (2) is withheld back coincideing with the upper edge (13) of well lid main body and is connected.
The base of well lid main body (12) is provided with fixing hole (9), and described fixing hole (9) is connected with well head through expansion bolt.
Described cant board (6) is gradient.
Cover plate (2) is provided with the convenient handle of opening (4) and makes things convenient for the door lock (3) of locking.
Utility model adopts full aluminium sheet to make, and makes it possibly produce spark in no instance, has overcome shortcomings such as combustion-supporting, not yielding.The utility model has simple in structure, and is reasonable in design, and processing more makes victory; Install faster; Operate lighter; The scene is more dustproof, in each petrol filling station of middle oil, oil depot and army use back safety relieved, but wide popularization and application.
