Description

Five anti-inlet for stom water grates

The utility model relates to a kind of grate gutter inlet.

Inlet for stom water well grate is a kind of ancillary structure on the road, and its function is to collect the ground rainwater runoff to enter storm sewer, makes the road surface not have ponding.Existing grate gutter inlet form is consistent decades, lose in a large number, grate gutter inlet is used as the rubbish mouth, admitted the sweeping rubbish that to admit, the inlet for stom water periphery is damaged, displacement, ring and jump, sedimentation, during the inlet for stom water water pouring, pile up foreign material, destroyed the water pouring function, again because inlet for stom water itself is provided with the difference of condition, sometimes inlet for stom water is more shallow, only there is 20-30cm dark, sometimes then 1 meter to 2 meters dark, for darker inlet for stom water, accept grate for two layers that security protection just should be set, otherwise only draw clearly inlet for stom water this will be a large amount of waste of manpower, giving to draw has clearly increased several times difficulty, prior this point is exactly the load-bearing of grate gutter inlet, by standard criterion, reach 18MP, the manhole of settling on the road then requires to reach 36MP, therefrom be not difficult to find out standard not necessarily, be main cause, grate gutter inlet is often crushed, changes fast that time of new grate is unable to catch up with crushing, for this reason, government will take out the input that a large amount of funds is carried out repetition every year, and based on above-mentioned all situations, it is extremely urgent to develop novel grate.

The purpose of this utility model provides a kind of five anti-inlet for stom water grates, makes it have five of anti-displacement, antitheft, anti-louds, anti-skidding, preventing dropped material and prevents functions.

The technical scheme of the anti-inlet for stom water grates of the utility model five: it comprises inlet for stom water, grate seat and places small opening shape cast iron grate above the inlet for stom water, and it is characterized in that: casting the grate that forms with nodular cast iron has four frames, girt strip and drain-gate; Grate seat both sides are prefabricated symmetrical rivet clasp bolt hole, a side have the dead rivet clasp axle below inlet for stom water of weldering, and rivet clasp axle and grate one side are movably hinged; Pre-buried at least three bearings below the inlet for stom water, on two layers of protected apron of preventing dropped material are arranged.

Above-mentioned grate four edge edge tilt, it is desk-top to be trapezoidal side.

Above-mentioned bearing is collapsible or telescopic type.

Above-mentioned two layers of protected apron are glass epoxies.

Above-mentioned grate one side has movable kerve, and is hinged with grate seat rivet clasp axle.

Be provided with T type rubber ring between above-mentioned grate and the grate seat.

There is anti-skidding line on above-mentioned grate drain-gate surface.

Above-mentioned anti-skidding line is cruciate flower or triangular prismatic type.

Advantage of the present utility model: five anti-inlet for stom water grates have anti-displacement, antitheft, anti-loud, anti-skidding, preventing dropped material five anti-functions.It is cast with nodular cast iron and forms, and has increased intensity; The grate body is anti-skidding, and it is desk-top to be the trapezoidal side of hypotenuse; Four rivet clasp bolt holes of prefabricated symmetry in both sides, below are with reinforced concrete prefabricated rectangular loop mouth, should supporting uses when reserving bolt and laying, can effectively prevent displacement, even heavily stone roller can displacement yet, mismatch; The weldering of rivet clasp axle extremely below road, has increased anti-theft feature, and the grabber is had no way of doing it; Pre-buried at least three folding bearings below inlet for stom water, on the preventing dropped material glass epoxy is arranged, can prevent from generally to weigh down the inlet for stom water bottom that thing directly falls darker, can be convenient to draw clearly the carrying out of work again, thereby human and material resources have been saved, when special circumstances take place, also can play preventing that the pedestrian from crashing into to the situation generation of hindering; The inlet for stom water inside casing is provided with T type rubber ring, has increased the tightness of grate gutter inlet with the circle mouth, thereby has reached the purpose of anti-sound; Four girt strips in grate surface and grate gap are wide, also have anti-skidding line, have pursued the unification of ratio, give comfortable sensation, have avoided grate crushed; Be provided with the movable kerve on the grate surface, be convenient to grate and open, can reach 180 ° of anti-angles of pulling after the unlatching, having under the situation of upright curb, also can open the angle that reaches more than 30 °, for condition has easily been created in the work of drawing inlet for stom water clearly.
