Abstract

The invention discloses roadside, a kind of urban operating mechanism road and receive the automatic opening-and-closing gutter cover for rain-water-collecting with sealing function that rainwater is used, it is formed by having the rectangular grate shape of arc key drop well lid, sealing grate and deadweight funnel.

This automatic opening-and-closing gutter cover for rain-water-collecting with sealing function, the function of automatic unlatching is arranged, sealing automatically can prevent effectively that dust and foreign material from sweeping in the catch-basin, guaranteeing does not simultaneously influence the storm-water drainage amount in the unimpeded inflow well of rainwater.And easy to install, can bear weight, become the plane with the road surface, do not influence vehicle and the pedestrian passes through.

Description

Automatic opening-and-closing gutter cover for rain-water-collecting with sealing function

The present invention relates to a kind of roadside, urban operating mechanism road that is used for and receive the receipts well lid that rainwater is used, is to receive the well lid with the rectangular comb shape that cast iron casting becomes, and its effect flows into rainwater in the sewer pipe fast by catch-basin.

This rectangular comb shape is received the well lid and is become the plane with the road surface, in the inflow sewer, can bear the pressure of vehicle rainwater can successfully stitch from combing rapidly when raining, and does not influence the pedestrian and vehicle passes through.Need mediation and draw in time smoothly rectangular comb shape well lid to be opened when digging in the pipeline deposit dirt mud and carry out cleaning work.

But in long-term the use, there is a defective, always dust and foreign material are swept in the catch-basin be exactly road cleaning personnel keep away when sweeping the road surface unavoidably, like this to causing the dust foreign material to pile up in the catch-basin, stop up underground pipeline, influence storm-water drainage, its consequence causes the serious ponding in road surface, plumbing work brings very big difficulty, influences pedestrian and normal vehicle operation.

The purpose of this invention is to provide a kind of rainwater well lid that has the automatic shutter sealing device, be used for preventing that dust and foreign material from sweeping in the catch-basin, and do not influence its drain function and storm-water drainage amount.

For achieving the above object, the present invention adopts the rectangular sealing of tooth bar shape to comb, and is loaded on rectangular comb shape rainwater well lid bottom surface, in order to seal the comb seam of rainwater well lid.Deadweight funnel and compression spring are arranged at the bottom that sealing is combed, after the deadweight funnel is filled water, gravity will seal to comb and depress, leaving the seam of combing, at this moment in the without hindrance inflow underground pipeline of rainwater, when road surface water is received when clean, the very fast emptying of water of deadweight funnel, weight saving, compression spring are combed tooth bar sealing and are pushed back with counter-force, so again with comb shape catch-basin cap seal sternly with to prevent that the dust foreign material from sweeping.

The advantage of automatic opening-and-closing gutter cover for rain-water-collecting with sealing function of the present invention is: (1) is simple and reasonable, and is easy to install.(2) energy automatic shutter guarantees that drain function is stable, can prevent that dust and foreign material from sweeping in the catch-basin.(3) can keep parallel, can bear weight, not influence normally passing through of pedestrian and vehicle with the road surface.

Below in conjunction with accompanying drawing example of the present invention is described in further detail.

The rectangular sealing comb of Fig. 1 tooth bar shape three-face view.

The rectangular comb shape of Fig. 2 rainwater well lid three-face view.

Fig. 3 funnel three-face view of conducting oneself with dignity.

Fig. 4 automatic shutter sealing rainwater well lid cross-section structure view.

By Fig. 1,2,3 as can be known, automatic opening-and-closing gutter cover for rain-water-collecting with sealing function of the present invention is made up of rectangular comb shape rainwater well lid, tooth bar shape sealing comb and deadweight funnel.The profile of rectangular comb shape rainwater well lid is basic identical with former well lid, is made up of gusset 17, grid section 16, the seam 17 of combing.Different is to have designed circular arc cover plate 5 and the strong seam 7 of combing together of wall slotted hole 8 shapes for anti-dust enters specially, but the wall highly suitable with import 6 arranged in the both sides in hole, play the effect that prevents that dust from entering and can make the unimpeded inflow of water, between water inlet 6 and the wall slotted hole 8, the gap that is equal to the seam 7 of combing is arranged on horizontal plane.Tooth bar shape sealing is combed and is made up of several tooth bars, and tooth bar 1 is trapezoidal, is convenient to the folding sealing, have on sealing is combed through hole 3, groove 4 be with comb shape well lid in conjunction with usefulness, slotted hole 2 is to design for weight reduction.The deadweight funnel is to be made of funnel 10, receipts tank 9, scupper 11, and notch 4 cooperates with comb shape well lid, and through hole 12 is in conjunction with usefulness with comb shape well lid.

As shown in Figure 4, the opening-closing structure of automatic opening-and-closing gutter cover for rain-water-collecting with sealing function is that to be bolt 14 with compression spring 15, deadweight funnel 10, sealing comb 18 is connected in series with on the comb shape well lid 19 by structure, deadweight funnel 10 is fastening by screw 13 with sealing comb 18, like this, when big yield in a steady stream flows into conduct oneself with dignity funnel 10 by wall slotted hole 8 along receiving tank 9 by water inlet 6, when deadweight funnel 10 water were full, gravity was with spring 15 compressions, open sealing and comb 18, water constantly flows in the well.Because the flow of scupper 11 is less than water inlet 6, so deadweight funnel 10 is in the flooding of current, weight can not alleviate, until the flow of water slowly to stopping, scupper 11 performances are leaked and are acted on weight reduction gradually, to seal comb 18 until compression spring 15 and upwards push back, sealing comb shape is received the overall process that the well lid is finished unlatching, sluicing, sealing.

Claims

1, roadside, a kind of urban operating mechanism road is received the rectangular comb shape that rainwater uses and is received the well lid, it is characterized in that: received by rectangular comb shape that well lid, the rectangular sealing of tooth bar shape are combed, the deadweight funnel is formed.Can accomplish automatic shutter, play preventing that dust and foreign material from sweeping the effect in the catch-basin, not influence drain function and storm-water drainage amount, but become the plane, can bear weight, not influence traffic and pass through with the road surface.
