Abstract
The utility model relates to a kind of well cover for sewer.It comprises lid, described lid inner side is provided with several piece arc expansion plate, the borehole wall is provided with supporting plate, the lower end of described arc expansion plate is provided with weight and rides on described supporting plate, and the distance of described supporting plate and well head is less than the length of described arc expansion plate, and lid center is provided with swingle, described swingle lower end is provided with rotation wing, described weight inner side has deep-slotted chip breaker, and when lid is during in normal operating condition, rotation wing can screw in deep-slotted chip breaker.At ordinary times, will rotate wing separated with weight, when rainwater is too many in sewer, because sewer has little time flood discharge, rainwater will wash from well head by lid, but due to the existence of arc expansion plate, make lid be suspended in well head top, can not be flushed away, also just can not make citizen come to harm; During maintenance, rotation wing is threaded in the deep-slotted chip breaker of weight, lid is mentioned just passable.
Description
(1) technical field
The utility model relates to urban operating mechanism field, particularly a kind of well cover for sewer.
(2) background technology
Modern city well cover for sewer is lost serious, is stolen on the one hand, runs on the other hand Severe rainstorm weather and is flushed away, and the sewer well casualty accident opening happens occasionally, and civic personal safety has been caused to great threat.
(3) summary of the invention
The utility model is in order to make up the defect of prior art, and a kind of well cover for sewer of being washed away by rainwater of preventing is provided.
The utility model is achieved by the following technical solution:
A kind of well cover for sewer, comprise lid, it is characterized in that, described lid inner side is to having several piece arc expansion plate, described arc expansion plate and the borehole wall match, the borehole wall is provided with supporting plate, and the lower end of described arc expansion plate rides on described supporting plate, and the distance of described supporting plate and well head is less than the length of described arc expansion plate.
The lower end of described arc expansion plate is provided with weight.
Described lid center is provided with swingle, and described swingle lower end is provided with rotation wing, and the quantity of described rotation wing is identical with the quantity of arc expansion plate, and described weight inner side has deep-slotted chip breaker, and when lid is during in normal operating condition, rotation wing can screw in deep-slotted chip breaker.
The beneficial effects of the utility model are:
At ordinary times, will rotate wing separated with weight, when rainwater is too many in sewer, because sewer has little time flood discharge, rainwater will wash from well head by lid, but due to the existence of arc expansion plate, make lid be suspended in well head top, can not be flushed away, also just can not make citizen come to harm; During maintenance, rotation wing is threaded in the deep-slotted chip breaker of weight, lid is mentioned just passable.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Fig. 1 is sectional structure schematic diagram of the present utility model.
In figure, 1 lid, 2 arc expansion plates, 3 weights, 4 deep-slotted chip breakers, 5 swingles, 6 rotation wings, 7 supporting plates, 8 boreholes wall.
(5) specific embodiment
Accompanying drawing is specific embodiment of the utility model.As shown in Figure 1, this kind of well cover for sewer, comprise lid 1, lid 1 inner side is to having two symmetrically arranged arc expansion plates 2, arc expansion plate 2 matches with the borehole wall 8, the borehole wall 8 is provided with supporting plate 7, the distance of supporting plate 7 and well head is less than the length of arc expansion plate 2, the lower end of arc expansion plate 2 is provided with weight 3, iron block for example, bloom etc., this weight 3 rides on supporting plate 7, lid 1 center is provided with swingle 5, the rotating handle of swingle 5 upper ends is positioned on lid 1 upper surface, swingle 5 is through after lid 1, its lower end is provided with two rotation wings 6, weight 3 inner sides have deep-slotted chip breaker 4, when lid 1 is during in normal operating condition, the outer end of rotation wing 6 can screw in deep-slotted chip breaker 4.
When lid 1 is placed on well head in normal operating condition, rotation wing 6 is separated with deep-slotted chip breaker 4, when in sewer, rainwater is too many, because sewer has little time flood discharge, rainwater will wash from well head by lid 1, but due to the existence of arc expansion plate 2, makes lid 1 be suspended in well head top, can not be flushed away, just can not make citizen come to harm yet; During maintenance, rotation wing 6 is threaded in the deep-slotted chip breaker 4 of weight 3, lid 1, arc expansion plate 2 is mentioned together with weight 3 just passable.
Except technical characterictic described in manual, all the other technical characterictics are those skilled in the art's known technology.
