Description
Technical Field
The utility model belongs to the technical field of municipal facilities, a sewer drainage pressure's well lid structure when can slowing down urban waterlogging is related to.
Background
The drainage well cover can guide rainwater on an urban road surface into a sewer in time, a sewer network under the urban area can guide the rainwater to be drained to a low-lying position such as a river, strong water flow is easily formed in the sewer when raining is urgent, strong raining can form strong water flow in the sewer after long-time strong raining, the strong water flow is reversely filled in the well cover position, the drainage pressure of the sewer is too high or drainage is not smooth, the existing well cover does not have sewer pressure relief capacity, so that the cover plate of the well cover is pushed open by water pressure in the well cover, when the well cover is separated from the well cover, a large potential safety hazard is formed on pedestrians and vehicles on the road surface, the well cover is shielded by accumulated water on the road surface to form a trap after being separated from the well cover, the potential safety hazard is formed on the pedestrians on the road surface, therefore, the pressure relief capacity is realized when the drainage in the sewer is not smooth, and otherwise, a safety accident is easily caused.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that exists to current technique, provide a sewer drainage pressure's well lid structure when can slowing down urban waterlogging, the utility model aims to solve the technical problem how to make the well lid can alleviate the drainage pressure in the sewer when urban waterlogging.
The purpose of the utility model can be realized by the following technical proposal: a well lid structure capable of relieving drainage pressure of a sewer when urban inland inundation is carried out is characterized by comprising a well base and a well lid, wherein the well base is hinged with the well lid; and a water drainage gap is formed between the outer wall of the cover plate and the inner wall of the drainage hole.
Furthermore, the lower surface of the covering plate is provided with a conical surface and a horizontal supporting surface, the horizontal supporting surface is positioned on the inner side of the conical surface, and the upper surface of the supporting sheet is matched with the lower surface of the covering plate.
Furthermore, the inner wall of the well seat is provided with a limiting check ring.
Furthermore, the guide rod is sleeved with a spiral spring positioned between the limiting nut and the positioning ring.
The sewer clearance that forms between drainage hole inner wall and the apron outer fringe is used for the road surface to the sewer internal drainage, and when the sewer internal drainage was not smooth, the pressure of walking water was great, can promote the apron and go upward, made the flow cross-section of wash port promote by a wide margin, can effectually alleviate sewer drainage pressure, can not push away the well lid from inspection shaft or well seat in urban waterlogging.
Drawings
Figure 1 is a cross-sectional view of the present manhole cover structure.
Figure 2 is an exploded view of the present manhole cover structure.
In the figure, 1, a well seat; 2. a well cover; 3. a support sheet; 4. a positioning ring; 5. a cover plate; 6. a guide bar; 7. a limit nut; 8. a conical surface; 9. a horizontal support surface; 10. and a limiting retainer ring.
Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the manhole cover comprises a manhole base 1 and a manhole cover 2, wherein the manhole base 1 is used for being connected with the ground, one side edge of the manhole cover 2 is hinged to the manhole base 1, the other side edge of the manhole cover 2 is detachably connected with the manhole base 1 through a bolt, so that the water pressure in a sewer cannot cause the separation of the manhole cover 2 from the manhole base 1, a drain hole is formed in the middle of the manhole cover 2, the diameter of the drain hole is about half of that of the manhole cover 2, a plurality of supporting pieces 3 are uniformly arranged on the inner wall of the drain hole in the circumferential direction, the inner end of each supporting piece 3 is slightly lower than the upper surface of the manhole cover 2, a positioning ring 4 located in the middle of the drain hole is formed at the inner end of each supporting piece 3, a guide rod 6 is arranged on the lower surface of each covering plate 5, the guide rod 6 is slidably connected in the positioning ring 4, a limiting nut 7 is connected to the guide rod 6 through a bolt, and a spring is arranged between the limiting nut 7 and the positioning ring 4; the outer diameter of the covering plate 5 is about 0.9 of the inner diameter of the drainage hole, a launching gap is formed between the outer wall of the covering plate 5 and the inner wall of the drainage hole, the launching gap is used for accumulated water on the road surface to enter the sewer, the structure is not easy to be blocked by impurities such as dirt entering the sewer from the road surface, the lower surface of the covering plate 5 is provided with a conical surface 8 and a horizontal supporting surface 9, the horizontal supporting surface 9 is positioned on the inner side of the conical surface 8, and the upper surface of the supporting piece is matched with the lower surface of the covering plate 5. When high pressure flowing water in the sewer promoted cover plate 5, cover plate 5 went upward, and cover plate 5's lower surface forms the guide structure to rivers, makes the pressure that cover plate 5 received obtain slowing down, also can effectually carry out the pressure release to the high pressure flowing water in the sewer simultaneously.
The inner wall of the well seat 1 is provided with a limiting retainer ring 10, and the limiting retainer ring 10 is used for supporting and positioning the well cover 2, so that the supporting strength is high when the upper part of the well cover is pressed.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
