Abstract
A float valve type road sewage well cover comprises frame flush and fixed with pavement and fence-shaped movable flat panel; a apron of truncated cone shape is under frame; a guide pillar beneath the flat panel is connected with middle part of flat panel (2); a guide pillar is covered with a floating body (4), the floating body (4) is connected beneath with a piston (6) which has characteristic of blocking harmful gas of sewage to overflow to road surface.
Description
Technical field
The utility model belongs to the road Sewage well cover, more specifically to a kind of float-valve type road Sewage well cover.
Background technology
Existing road Sewage well cover is shelved on the frame that flushes and fix with road surface by the surface plate of a paliform and is formed.Water is gone into sewer by the fence orifice flow under the road, and the pernicious gas of sewer then overflows from the fence hole to the roadway pollution air, especially to overlooking household's harm maximum.
Summary of the invention
The purpose of this utility model is that the shortcoming that overcomes prior art provides a kind of float-valve type road Sewage well cover.
A kind of float-valve type road of the utility model Sewage well cover, comprise the frame that flushes and fix with road surface and the free cheek plate of paliform, there is round table-like apron described frame below, and the centre of described surface plate is connected with guide pillar downwards, guide pillar is with buoyancy aid outward, is connected with piston under the described buoyancy aid.
A kind of float-valve type road of the utility model Sewage well cover has following beneficial effect compared with the prior art:
The piston that the pernicious gas of sewer is subjected to be connected with under outer buoyancy aid that is with of guide pillar and the buoyancy aid stops and is difficult to directly overflow to road surface from the fence hole, thereby avoids polluting the road surface air.
Description of drawings
Fig. 1 is a structure sectional view of the present utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
Shown in Figure 1, a kind of float-valve type road of the utility model Sewage well cover, comprise the frame 1 that flushes and fix with road surface and the free cheek plate 2 of paliform, there is round table-like apron described frame 1 below, the centre of described surface plate 2 is connected with guide pillar 3 downwards, be with buoyancy aid 4 outside the guide pillar 3, described buoyancy aid is connected with piston 64 times, and buoyancy aid 4 borrows connecting rod 7 to engage with piston 6.
The following water of road surface flow to the ponding chamber that has round table-like apron and piston 6 to constitute by described frame 1 below from the fence hole 5 of surface plate 2, buoyancy aid 4 was along carrying on guide pillar 3 come-ups and the drive piston 6 when ponding reached certain altitude, then ponding flow to sewer, round table-like apron when road surface does not have following water below the described frame 1 and the piston 6 closely contact pernicious gas that stops sewer 5 overflows to road surface from the fence hole, thereby avoids contaminated air.
Claims (1)
