Abstract

The utility model relates to a drainage lid or drainage grate, which is designed to resolve the technical problem that drainage holes of like products are blocked by impurities (such as dust, stones, paper chips and the like) which are smaller than the drainage holes. The design points include that outer frames of the lid plate are inclined edges in the shapes of right trapezoids, the inclined edges face towards the center of the lid plate, symmetrical inclined edges are connected via a plurality of supporting beams and middle beams to form drainage holes, and heights of the supporting beams and the middle beams are identical to the height of perpendicular edges of the inclined edges. Once the drainage holes are blocked by impurities smaller than the drainage holes, the impurities can drop into an urban road drainage system via the inclined edges easily by sweeping or pedaling of people or extruding of vehicle tires. The drainage lid is reasonable in design, simple in structure, low in cost, convenient in use, fine in drainage effect, adaptable to arrangement of the urban road drainage system and draining of road surface sewage or rainwater.

Description

Drain cap

Technical field

The utility model relates to the road drainage device, is a kind of drain cap or title draining grate.

Background technology

As everyone knows, drain cap (or claiming the draining grate) is one of well lid, is a kind of well lid that mesh is arranged in order to parting specifically, and it is mainly used in draining on both sides of the road.Sewage or rainwater enter the urban road drainage system of road both sides by drain cap, patent No. ZL2007200003273.7 as the Chinese patent literature publication, January 23 2008 notice of authorization day, utility model title " a kind of water drain grid cover that makes things convenient for draining ", this water drain grid cover comprises the inlet for stom water that is provided with on water drain grid cover plate and the water drain grid cover plate, and its main points are that the groove with the inlet for stom water conducting is offered in described water drain grid cover plate upper surface.But above-mentioned grating or drain cap are in use, and mesh is stopped up less than the foreign material of mesh in the road both sides, causes road both sides ponding.

Summary of the invention

For overcoming the deficiency of above-mentioned existence, the utility model purpose is a kind of drain cap that has oblique gathering sill that provides to this area, makes it solve the technical problem of piling up obstruction like product drain hole in the existing urban road less than the foreign material (as dust, finger stone, little paper scrap etc.) of drain hole.The purpose of this utility model is achieved by the following technical solution.

A kind of drain cap, the well lid plate of this drain cap constitutes the plurality of rows water hole by outer rim, brace summer, middle girder, the width of mesh of drain hole is according to real material and load bearing requirements designed size, and this drain cap adopts materials such as polymer composite, cast iron and steel fibrous concrete to make.The outer rim that its design main points are described well lid plates is oblique limit, oblique limit is at right angles trapezoidal, oblique limit is towards well lid plate center, and the oblique limit of symmetry connects and composes drain hole by some brace summers, middle girder, and brace summer, middle depth of beam are identical with the vertical edges height on oblique limit.Road foreign material on both sides of the road come together in four oblique limits of well lid plate by current, and flow into the urban road drainage system with current by drain hole.Foreign material less than drain hole are jammed in drain hole, only need that cleaning or people are foot-operated, the foreign material on oblique limit on the vehicle tyre extrusion drainage hole, and foreign material can enter the urban road drainage system by oblique limit easily.

At least two adjacent edges of the drain hole of described well lid plate are oblique limit, and the junction constitutes arcwall face.Obstruction foreign material less than drain hole in the arcwall face on adjacent oblique limit are foot-operated by people, vehicle tyre is crumbed after pushing, and enters the urban road drainage system.

Support by middle girder between the brace summer of described well lid plate and the brace summer.Constitute difformity between middle girder and the brace summer and arrange, drain hole is different length.

Described brace summer is made as oblique limit, and the intermediate altitude of brace summer is identical with the vertical edges height on oblique limit.As shown in Figure 5, people or vehicle are walked on road well lid plate on both sides of the road or when current, the situation that is unlikely to cave in.

Described brace summer is provided with guiding gutter.As shown in Figure 4, guiding gutter is used for well lid plate face rainwater or comes together in the water conservancy diversion of the sewage of well lid plate face, and guiding gutter can design different geometries, flows into the urban road drainage system by guiding gutter.

The utility model is reasonable in design, simple in structure, cost is low, easy to use, drainage effect is good, is applicable to the layout of urban road drainage system, and the current drainage of road surface sewage or rainwater.

The specific embodiment

Embodiment is further described structure of the present utility model and use in conjunction with the accompanying drawings.As Fig. 1, Fig. 4, Fig. 5, shown in Figure 6, four limits of this well lid plate 1 are oblique limit 102, and oblique limit and brace summer 103 connect and compose drain hole 101.As Fig. 4, Fig. 5, shown in Figure 6, connect by middle girder 104 between the brace summer, further increase the holding capacity of well lid plate face.As shown in Figure 4, brace summer is provided with guiding gutter 105, and guiding gutter designs different shapes, is used for the water conservancy diversion of well lid plate face rainwater or sewage.The vertical edges on oblique limit and brace summer, middle depth of beam are identical, make the people or the current vehicle of walking on the well lid plate not produce the depression sense.Above-mentioned drain hole, oblique limit, brace summer, middle girder, guiding gutter and well lid plate are connected as a single entity, by injection moulding or casting one-shot forming.

The utility model is installed on the well head on the drainage system on urban road both sides, because the road is lower than road surface in the middle of the road in the road surface on both sides of the road, rainwater is carried foreign material secretly and is compiled to the drain cap of road both sides, flows into the urban road drainage system through the oblique limit of well lid plate.Pile up less than the foreign material of drain hole and to stop up drain hole, crumb make the stressed extruding of foreign material of drain hole by people's walking or vehicle current after, the oblique limit by the well lid plate enters the urban road drainage system.

The utility model is not easy to cause the foreign material less than drain hole to pile up at drain hole than existing common drain cap, stops up rainwater or sewage and flows into the urban road drainage system.
