Abstract

The utility model relates to a sewer cover which comprises a cover body, a safety net and a fixed base. The cover body is of a disc-shaped structure, four to six protruding columns are processed on the periphery of the cover body, two normally-opened drainage holes are formed in the symmetric positions of the cover body, at least one self-opening and self-closing drainage channel is arranged around each normally-opened drainage hole, the self-opening and self-closing drainage channels are composed of baffles and springs, the baffles are arranged below the cover body, one ends of the baffles are connected with the cover body through fixing shafts, the baffles can rotate around the fixing shafts within the range of 0-900, and the other ends of the baffles are connected with the cover body through the springs. Four to six protruding columns are processed on the periphery of the safety net. The fixed base is in a hollow cylindrical shape, clamping grooves corresponding to the protruding columns of the cover body and the protruding columns of the safety net in position and shape are formed in the inner circle of the fixed base from top to bottom, and waterproof fluorescent films are attached to the top face of the cover body and the top face of the fixed base respectively. The sewer cover is reasonable in structure and fast in drainage, and urban inland inundation occurring when dust enters a sewer and a large amount of rainfall occurs can be prevented.

Description

A kind of Sewage well cover

Technical field

The utility model relates to a kind of Sewage well cover, belongs to municipal drainage facility technology field.

Background technology

Sewer pipe is municipal engineering important in urban construction, and for the draining in city, Sewage well cover is one of the most basic equipment of urban sewerage and drainage system, for covering the entrance of sewer pipe, prevents that vehicle or personnel from causing danger because of sewer mouth.Current Sewage well cover is made up of lid and manhole cover base conventionally, lid adopts iron disc structure mostly, offer two drain holes in symmetric position above, in actual use, exist well lid drain hole to arrange very few, in the time that surface gathered water is too much, well lid drainage speed is slower, causes the problem of surface gathered water.

Utility model patent " a kind of Sewage well cover structure fast ", notice of authorization CN 202610959 U, a kind of manhole cover structure of quick lower water is disclosed, in the positive outer rim of well lid body, a ring shape well lid outer is set, edge in one circle round manhole cover is set between well lid body, in annular well lid outer and round manhole cover, between edge, some ribs are set, on the body between two ribs, be provided with the lower mouth of a river, although this utility model has been accelerated the drainage speed of Sewage well cover to a certain extent, but owing to setting up the quantity at the lower mouth of a river, dust on road, foreign material etc. easily enter sewer pipe by the lower mouth of a river, cause the obstruction of sewer pipe, and bad smell in sewer will come out from the lower mouth of a river, affect urban environment, if it is too small that open in the aperture at the lower mouth of a river, in the time running into short time a large amount of rainfall, still there will be the problem of surface gathered water.

Summary of the invention

The purpose of this utility model is to overcome the shortcoming existing in prior art, provides a kind of rational in infrastructure, and draining is rapid, has the Sewage well cover from open and close type drainage channel.

For achieving the above object, the utility model adopts following scheme:

A kind of Sewage well cover, comprise lid, safety net and holder, described lid is disc-shaped structure, the outer rim of lid is processed with 4-6 projection, and on lid, symmetric position is provided with two water holes that often begin to rehearse, and each water hole that often begins to rehearse is at least provided with 1 from open and close type drainage channel around, describedly formed by baffle plate and spring from open and close type drainage channel, baffle plate is positioned at the below of lid, and one end is connected with lid by fixed axis, and baffle plate can be around fixed axis at 0-90 ⁰in scope, rotate, the baffle plate other end is connected with lid by spring; The outer rim of described safety net is processed with 4-6 projection; Described holder is the cylindrical of hollow, is respectively equipped with from top to bottom the projection position of corresponding lid and safety net and the draw-in groove of shape in the inner circle of holder, at the end face of lid and holder all with one deck waterproof fluorescent film.

Described safety net is the grid-like net structure of being made up of reinforcing bar.

The number of described lid and safety net outer rim projection is preferably 4.

Describedly be shaped as rectangle or circle from open and close type drainage channel.

Distance between described lid and safety net is 20-30 centimetre.

Operating principle: under normal circumstances, the baffle plate that is positioned at lid below is close on lid, close from open and close type drainage channel, in the time running into the situation that occurs a large amount of precipitation in the short time, road surface there will be ponding, ponding can be oppressed baffle plate, one end that baffle plate is connected by spring with lid can be upheld, now baffle plate can turn an angle around fixed axis, open from open and close type drainage channel, can be by getting rid of fast surface gathered water from open and close type drainage channel, after ponding is drained, the spring contraction that baffle plate is connected with lid, baffle plate returns to normal position.

The beneficial effects of the utility model are: by arranging from open and close type drainage channel, dust, the rubbish etc. that can prevent under normal circumstances road surface enter sewer pipe in a large number by drainage channel, cause the obstruction of sewer pipe, can also reduce unpleasant gas in sewer pipe is dispersed in environment, in the time running into a large amount of rainfalls and occur surface gathered water, can automatically open drainage channel, effectively prevent the appearance of city waterlogging; Safety net is set below lid, can prevents that pedestrian or vehicle drop to the generation of the medium security incident of sewer pipe because well lid lid is lost; Lid, safety net and holder are connected with draw-in groove by projection, and it is simple and easy, convenient to install, and is convenient to dismounting, maintenance; At the end face of lid and holder all with one deck waterproof fluorescent film, can be night pedestrian and Vehicle Driving Cycle warning function is provided.
