Description
Technical field
The utility model is related to well lid, and in particular to a kind of convenient installation of bayonet type from pressure release inspection well cover.
Background technology
At present, for the convenience of unlatching, most of inspection well cover is installed in a manner of being directly placed on well head.
When experience rainstorm weather causes urban underground water drainage pipe road product completely rainwater, some inspection well covers are not enough to bear to carry out artesian well because of deadweight
Under hydraulic pressure and jacked up, washed away, lost, which results in direct economic loss.The well head directly exposed is to passing car
, pedestrian will also result in huge potential safety hazard, easily trigger security incident.If using traditional fixed forms such as bolt fixations
Well lid is directly anchored on ground, can cause certain trouble to regularly opening again.Due to city the presence of potential difference, knot
Law of connected vessels is closed, it is interim whenever rainstorm weather, if the hydraulic pressure in drainage pipeline can not be reduced, then once well lid quilt
Jack up the place washed away and the situation that well lid is pushed up away still occurs, lose-installing again-in the endless loop lost so as to be absorbed in.
Utility model content
The utility model in view of the shortcomings of the prior art, and it is an object of the present invention to provide a kind of convenient installation of bayonet type from pressure release basement
Well lid.
Technical scheme is used by the utility model：
A kind of convenient installation of bayonet type from pressure release inspection well cover, be made up of movable structure and firm banking, it is described to live
Dynamic structure is formed by inner ring is nested with outer ring, and the inner ring is made up of top cover and annular wall, and top cover and annular wall snap connection, top
Lid diameter is more than annular wall external diameter, is provided with discharge outlet in annular wall, annular wall lower end is provided with flange；The outer ring casts for ring-type
Ironware, the internal diameter of the outer ring are more than cap diameter but are less than flange outside diameter, and the height of the outer ring is more than cap height but small
In top cover and the height sum of annular wall, the inwall of the outer ring is provided with position limiting structure, and top cover is nested in outer ring, outer ring
Circumferentially equally distributed cylindrical bump is provided with outer wall, be provided with the inwall of firm banking with it is cylindric on outer ring outer wall
Raised corresponding bayonet socket, outer ring top cover, outer ring and are consolidated by cylindrical bump on outer wall and firm banking bayonet socket nested encryptions
Determine base to keep flushing in the horizontal plane.
In such scheme, block button hole is provided with the top cover, the upper end of annular wall is provided with buckle structure, top cover and ring
Shape wall is used and rotatably snapped connection.
In such scheme, the height of the outer ring (5) is less than the discharge outlet lower end in annular wall to the vertical range of flange.
In such scheme, screen pack is provided with the discharge outlet.
In such scheme, the discharge outlet is circumferentially uniformly distributed, including at least three.
In such scheme, the discharge outlet is close to annular wall upper end.
In such scheme, the cylindrical bump comprises at least three.
Due to the application of bayonet-like structures, the installation of the well lid is extremely convenient.After well lid installation, inner ring is limited in
Among outer ring, can only move up and down vertically and without departing from, the influence top cover under normal condition due to gravity maintains an equal level with ground,
It is connected and fixed between outer ring and firm banking in the form of bayonet socket on ground.When by underground hydraulic pressure, inner ring will be lifted
Rise and the discharge outlet on annular wall top is basseted, the rainwater of underground is arranged earthward, realize pressure release.When pressure release completion, well
When lower hydraulic pressure declines, inner ring can be fallen after rise to normal condition.When well lid needs to open, it is only necessary to by the outer ring edge side opposite with installation
Can easily it be opened to rotating to an angle.
The beneficial effects of the utility model：The utility model provide a kind of convenient installation of bayonet type from pressure release inspection shaft
Lid, it can realize the function of being automatically drained out underground rainwater while ensureing that inspection well cover unlatching facilitates, prevent because well lid surprisingly rushes
Walk to lose and caused by economic loss and potential safety hazard, while solve loss and the endless loop lost-be installed-again.

Embodiment
In order to more fully understand the utility model, content of the present utility model is furtherd elucidate with reference to embodiment, but
Content of the present utility model is not limited solely to following example.
Embodiment 1
Reference picture 1~6, a kind of convenient installation of bayonet type from pressure release inspection well cover, by movable structure and firm banking group
Into the movable structure is formed by inner ring is nested with outer ring, and the inner ring is made up of top cover (1) and annular wall (2), the top
Block button hole (10) is provided with lid (1), the upper end of annular wall (2) is provided with buckle structure (11), top cover (1) and annular wall (2)
Using rotatably snapping connection, top cover (1) diameter is more than annular wall (2) external diameter, annular wall (2) upper end be provided with three it is circumferentially equal
The discharge outlet (3) of even distribution, screen pack (12) is provided with discharge outlet (3), annular wall (2) lower end is provided with flange (4)；It is described
Outer ring (5) is annular casting iron part, and the internal diameter of the outer ring (5) is more than the diameter of top cover (1) but less than the external diameter of flange (4), institute
The height for stating outer ring (5) is slightly larger than the height of top cover (1) and is less than the lower end of discharge outlet (3) to the vertical range of flange, described
The inwall of outer ring (5) is provided with position limiting structure (6), and top cover (1) is nested in outer ring (5), and three are provided with the outer wall of outer ring (5)
