A kind of trapped well
Technical field
The present invention relates to a kind of trapped well.
Background technology
The rain sewage conduct net that utilizes in cities and towns carries out rainwater and sewage emissions, be maintenance and the maintenance that makes things convenient for grid, the node of grid is provided with sink hole, what flow in the sink hole is rainwater and sewage, have smell, particularly the weather sweltering heat in summer the time, smell comes out the sanitation of environment that has a strong impact on people's lives district periphery, present sink hole does not generally possess the function that prevents that smell from distributing, and causes sink hole periphery smell heavier.
Summary of the invention
The technical problem to be solved in the present invention is: for solving the deficiencies in the prior art, provide a kind of trapped well.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of trapped well, comprise the well body, inflow pipe that is connected with the import of well body and the effuser that is connected with the outlet of well body, the upper end of well body is provided with bellmouth, side near effuser in the well body is provided with the water seal shutter that prevents that smell from overflowing, described water seal shutter comprises the shrouding of level and vertical dividing plate, described shrouding front end and bellmouth are tightly connected, the shrouding rear end is provided with the handle that is used to lift water seal shutter, leaves the gap between described dividing plate lower end and the well body bottom.
Further, described well body inwall bilateral symmetry is provided with keeper, and described dividing plate is installed in the keeper, is provided with O-ring seal between described dividing plate and the keeper.
Further, described well body is cylindrical, and described shrouding is the circular arc plate.
Further, described dividing plate is provided with at least one reinforcing rib.
Further, described dividing plate is provided with three reinforcing ribs.
Beneficial effect: the invention solves the defective that exists in the background technology, be provided with water seal shutter, effuser and well body are separated, can prevent that smell from distributing.

The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
A kind of trapped well shown in Figure 3 as Fig. 1 Fig. 2, inflow pipe 2 that comprise well body 1, is connected and the effuser 3 that is connected with 1 outlet of well body with 1 import of well body, the upper end of well body 1 is provided with bellmouth 4, side near effuser 3 in the well body 1 is provided with the water seal shutter 5 that prevents that smell from overflowing, described water seal shutter 5 comprises the shrouding 51 of level and vertical dividing plate 52, described shrouding 51 front ends and bellmouth 4 are tightly connected, shrouding 51 rear ends are provided with the handle 53 that is used to lift water seal shutter 5, leave the gap between described dividing plate 52 lower ends and well body 1 bottom.
Described well body 1 inwall bilateral symmetry is provided with keeper 11, and described dividing plate 52 is installed in the keeper 11, is provided with O-ring seal between described dividing plate 52 and the keeper 11.Described well body 1 is cylindrical, and described shrouding 51 is the circular arc plate.Described dividing plate 52 is provided with three reinforcing ribs.
If well body 1 is circular, then shrouding 51 is corresponding circular arc plate; If well body 1 is square, then shrouding 51 is the square of correspondence.
Introduce the present invention below in conjunction with concrete the use.
In the time of need carrying out the smell isolation, in the side near effuser water seal shutter 5 is installed, the obstruct that shrouding 51 and dividing plate 52 are formed effuser 3 can not come out smell.When needs are drawn clearly in to well, by handle 53 water seal shutter 5 is taken out, do not influence and draw operation normally clearly.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the manual, must determine its technical scope according to the claim scope.
