Description
Technical field
The utility model relates to a kind of novel manhole cover that has exhaust flood discharge skylight that is applicable to that industries such as feedwater, draining, air feed, heat supply, telecommunications, electric power, fire-fighting are used.
Technical background
In the recent period, the accident that the frequent well lid " biogas detonation " that occurs causes casualties has become the social concern that people " turn pale at the mention of the tiger ".Yet, be convenient to open well lid and the aperture crotch coupling though be provided with on traditional well lid, but the concentration of the biogas that the rotten putrefaction in the down-hole produces still can't overcome greater than the hidden danger of 5% o'clock existing " biogas detonation " casualty accident and traditional well lid also exists when meeting heavy rain flood discharge smoothly also need manually open the defective that well lid comes flood discharge, can not be satisfactory in the historical facts or anecdotes usefulness.
Summary of the invention
The defective of flood discharge smoothly in the time of can't overcoming " biogas detonation " casualty accident and meet heavy rain in order to overcome that traditional well lid is existing, a kind of more reasonable structure of special proposition, there is the working service of smooth flood discharge function easy when having desirable anti-" biogas detonation " function and meeting heavy rain, the novel manhole cover that has exhaust flood discharge skylight that cost is low is to remedy present deficiency.
For achieving the above object, the technical solution of the utility model is achieved in that a kind of novel manhole cover that has exhaust flood discharge skylight, it is characterized in that this manhole cover comprises that the well lid main body that is provided with at least one exhaust flood discharge skylight above one and one prop up seat ring with the matching used well lid main body of well lid main body; The window frame in the exhaust flood discharge skylight on the described well lid main body is other is positioned at the window frame reinforcing rib that the well lid main body back side is provided with boss type; Described well lid main body is to be assembled into this manhole cover by the walling crib support convex edge contraposition coupling that the main body pressure-bearing convex edge at its back side and well lid main body are propped up on the seat ring.
For achieving the above object, the technical solution of the utility model is achieved in that a kind of novel manhole cover that has exhaust flood discharge skylight, it is characterized in that this manhole cover comprises that the well lid main body that is provided with at least one exhaust flood discharge skylight above one and one prop up seat ring with the matching used well lid main body of well lid main body; The window frame in the exhaust flood discharge skylight on the described well lid main body is other is positioned at the window frame reinforcing rib that the well lid main body back side is provided with boss type; Described well lid main body is to prop up the hinge shaft sleeve contraposition on the seat ring and prop up walling crib on the seat ring by the assembling between hinge shaft sleeve, hinge axis nose and hinge pin and the main body pressure-bearing convex edge by the well lid main body back side and well lid main body and support convex edge contraposition coupling and be assembled into this manhole cover by the hinge axis nose on it and well lid main body.
The thickness of the window frame reinforcing rib of the boss type that is positioned at the setting of the well lid main body back side that preferably, the window frame in the exhaust flood discharge skylight on the described well lid main body is other is preferably at 3～30 millimeters.
The exhaust flood discharge skylight that arranges on the described well lid main body can have a plurality of, can be multiple shape, and preferably symmetrical geometry is arranged; Certainly, the window frame in the exhaust flood discharge skylight on the described well lid main body is other is positioned at the reinforcing rib that well lid main body front also can be provided with projection, and its thickness is preferably at 1～3 millimeter.A kind of novel manhole cover that has exhaust flood discharge skylight can be made by metal material etc., can pass through kinds of processes, forms as methods such as casting, die forging, cold-heading, machines, preferably adopts materials such as cast steel or ductile iron.
(see also Fig. 1 to Fig. 7) during use, earlier the well lid main body is propped up seat ring and be fixed on well head by the concrete cast, again main body pressure-bearing convex edge and the well lid main body of well lid main body by its back side propped up walling crib on the seat ring and supported convex edge coupling contraposition and put the well lid main body into and prop up in the seat ring, being about to this manhole cover assembling installs (at this moment, because the effect in the exhaust flood discharge skylight that arranges on the well lid main body, can guarantee that under the situation that the biogas that the rotten putrefaction of down-hole produces is built up gradually biogas concentration under its well lid all the time less than 5%, has desirable anti-" biogas detonation " function; When chance heavy rain current are smooth, guarantee its flood discharge smoothly by the exhaust flood discharge skylight that arranges on its well lid main body); When need are opened this manhole cover, only need on the well lid main body and the aperture crotch coupling are inserted in the crotch contraposition on the crotch instrument, up mention, this well lid can be opened.
The utlity model has following major advantage: 1, rational in infrastructure, the function of the smooth flood discharge of energy when having desirable anti-" biogas detonation " function and meeting heavy rain; 2, mature production technology is used simply, and easy to maintenance, cost is low; But 3 standardization can be exchanged general.
This well lid metal material that preferably has drawn from forms through methods such as casting, die forging, cold-heading, machines.
