Abstract
A multilayer well lid, described well lid is comprised of concentric circles ring cowling and the center dome of hollow cylinder volume surrounding support and supporting connection successively; At outer internal stent, netted or paliform protective frame is laterally installed, each concentric circles ring cowling is socketed successively and forms whole dome, and the external diameter of whole dome equates with outer shelf inner diameter, at innermost layer concentric circles ring cowling inner circle mounting center dome; At donut, cover and offer drain hole, in center circle, cover the movable handle of installing.The utlity model has delicate structure, the advantage such as easy-to-use.
Description
Technical field
The utility model relates to a kind of public drainage, especially a kind of Sewage well cover.
Background technology
As everyone knows, Sewage well cover is the most basic in urban sewerage and drainage system, most important terminal facilities.At present, Sewage well cover adopts circular lid or rectangle lid structure mostly.Yet for present Sewage well cover, the size of its drain hole and position all cannot be adjusted afterwards once arranging, and are therefore running in rainstorm weather, burgeoning displacement cannot carry out draining by that slight drain hole of common Sewage well cover at all and dredge.For this reason, very easily cause the problem of impeded drainage.In addition, once the drain hole of well lid is blocked, being bound to should drainage effect.Moreover known Sewage well cover all lacks ballistic support measure, once and lid is stolen or damage, when people or vehicle compressing lid, be just easy to fall into the drainage pipe of below.Generally speaking, present Sewage well cover cannot meet people's demand.
Summary of the invention
The purpose of this utility model is to provide a kind of multilayer well lid that can manually adjust displacement and possess safeguard function.
Well lid described in the utility model is comprised of concentric circles ring cowling and the center dome of hollow cylinder volume surrounding support and supporting connection successively; At outer internal stent, netted or paliform protective frame is laterally installed, each concentric circles ring cowling is socketed successively and forms whole dome, and the external diameter of whole dome equates with outer shelf inner diameter, at innermost layer concentric circles ring cowling inner circle mounting center dome; At donut, cover and offer drain hole, in center circle, cover the movable handle of installing.Cylindrical at concentric circles ring cowling is provided with outstanding dop, and at the draw-in groove of inner circle relevant position processing depression, adjacent two concentric circles ring cowlings are connected to each other by dop and draw-in groove.
Compared with the prior art, the beneficial effects of the utility model are: reasonable in design, convenient and practical, safe and reliable, and can manually adjust displacement, and can prevent that people's car from falling the danger of well.
Accompanying drawing explanation
Fig. 1 is top view of the present utility model.
Fig. 2 is outer rack assumption diagram of the present utility model.
Reference numeral: 1 is that outer support, 2 is that dome centered by concentric circles ring cowling, 3,4 is that protective frame, 5 is that drain hole, 6 is that handle, 7 is that dop, 8 is draw-in groove.
The specific embodiment
In the top view of the present utility model shown in Fig. 1, described well lid is comprised of concentric circles ring cowling 2 and the center dome 3 of hollow cylinder volume surrounding support 1 and supporting connection successively; At outer internal stent, netted or paliform protective frame 4 is laterally installed, each concentric circles ring cowling is socketed successively and forms whole dome, and the external diameter of whole dome equates with outer shelf inner diameter, at innermost layer concentric circles ring cowling inner circle mounting center dome; At donut, cover and offer drain hole 5, in center circle, cover the movable handle 6 of installing.Cylindrical at concentric circles ring cowling is provided with outstanding dop 7, and at the draw-in groove 8 of inner circle relevant position processing depression, adjacent two concentric circles ring cowlings are connected to each other by dop and draw-in groove.
Embodiment mono-: outer support, concentric circles ring cowling and center dome all adopt metal to make, weld metal paliform protective frame in outer support.During normal use, all concentric circles ring cowlings are socketed to rear mounting center dome successively, form unitary circular cover body structure, now by the normal draining of the drain hole on circular ring cover.In rainstorm weather, people hold handle and upwards mention center dome, then according to displacement, can successively take off concentric circles ring cowling, and vacancy is supported by the protective frame in outer support, prevent that pedestrian and vehicle from falling in well, now just greatly discharge capacity carry out draining.
