Abstract

The utility model relates to a 'three-prevention ' rainwater grate capable of theft prevention, dust prevention, and deodorization, which is formed by the connection of a grate ring, a grid plate, a rotating shaft, and a spring, wherein, a grate is connected with the grate ring by the rotating shaft; the grate can be opened and covered, is difficultly taken off, and plays a role of the theft prevention; the grid plate is connected with the grate by the rotating shaft, and is supported by the spring which is arranged on the rotating shaft. When the utility model meets a rain, the grate plate is opened by the pressure of the rainwater, water flows inwards a rainwater opening. When the utility model does not meet the rain, the grate plate is engaged with the grate together by the support of the spring for preventing the dust and foreign matters on streets from entering the rainwater opening and for preventing the odor transferred into the rainwater opening from a pipeline from being emitted outwards.

Description

Antitheft, dustproof, deodorization rainwater bamboo comb

The utility model relates to the corollary apparatus that a kind of rainwater is collected mouthful, and the dust in the time of especially preventing stolen and no rain on the street, foreign material etc. enter, or the rainwater double-edged fine-toothed comb that outwards distributes of the interior stink of pipeline.

At present, the rainwater double-edged fine-toothed comb that known rainwater is collected mouth is " national water supply and drainage standard collective drawings " (S2) double-edged fine-toothed comb of middle design, just the material difference is adopted in various places, its planform changes very little, the rainwater double-edged fine-toothed comb of these perforates can only play the effect that enters rainwater and guarantee the driving pedestrian, but, during to no rain, dust on the street, leaf, entering of foreign material such as paper scrap is overwhelming, has created condition for the inside sweeping rubbish of part environmental sanitation cleaning personnel, has increased the quantity of refuse of inlet for stom water and pipeline, influenced the flow of inlet for stom water and pipeline, simultaneously, the pipeline stink that passes inlet for stom water into also can be discharged contaminated air by the rainwater double-edged fine-toothed comb of perforate is outwards a large amount of, moreover, because the rainwater double-edged fine-toothed comb does not have any fastening devices, and is stolen easily, cause the driving pedestrian dangerous.

The purpose of this utility model provides a kind of rainwater double-edged fine-toothed comb, and it can not only be antitheft, and dust and the foreign material on the street enter in the inlet for stom water can prevent non-rainy day the time, or pipeline passes into, and the stink of inlet for stom water outwards distributes.

The utility model is achieved in that a side of double-edged fine-toothed comb connects together by the rotating shaft and the side of enclosing of combing, and double-edged fine-toothed comb can be opened and cover, and can not take away, and plays antitheft effect.One end of two grate plates middle part below rotating shaft and double-edged fine-toothed comb connects together, grate plate can be rotated up and down, corrosion-resistant spring is installed in the rotating shaft, both ends of the spring is supporting two grate plates, grate plate is coincide with double-edged fine-toothed comb closely be in the same place, like this, stink in the inlet for stom water is difficult for out, during no rain, dust on the street and foreign material also are difficult for entering in the inlet for stom water, play the effect of dustproof and deodorization.In addition, when rainy, the rainwater that inlet for stom water is collected is subdued grate plate, and amount of rainfall is big more, grate plate is downward more, flow is big more, and on the contrary, amount of rainfall is more little, grate plate more upwards, so that totally-enclosed, the heap shape hole that the rainwater of trace only needed to reserve enters in the inlet for stom water and get final product, and this can guarantee fluviation and the pedestrian's that drives a vehicle safety equally.

Owing to adopted such scheme, both guaranteed the driving pedestrian of former rainwater double-edged fine-toothed comb and the effect of flowing water, the sewage when having prevented no rain again in inlet for stom water enters rubbish or pipeline outwards gives an offensive smell, and simultaneously, can prevent that the rainwater comb is stolen.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a horizontal frontal plane structure chart of the present utility model

Fig. 2 is an antiplane structure chart of the present utility model

Fig. 3 is the I-I sectional view of Fig. 1

Fig. 4 is the II-II sectional view of Fig. 1

Fig. 5 is the III-III sectional view of Fig. 1

Among the figure: 1. comb and enclose 2. 3. 4. 5. rotating shaft of rotating shaft of grate plate of double-edged fine-toothed comb

6. 7. spring piles 8. open hole of shape hole

In Fig. 1,4. the circle side 1. of combing is connected by rotating shaft with a double-edged fine-toothed comb side 2., and can relatively rotate.Comb figure 1. around, rotating shaft two ends 4. are embedded in the road surface when road construction, double-edged fine-toothed comb discharge orifice 2. is 2. shape hole, double-edged fine-toothed comb can be opened and be difficult for taking away, and it is comparatively convenient to adopt open hole 8. to collude when 2. double-edged fine-toothed comb opens to open.

In Fig. 2, two grate plates are arranged 3., 5. an every grate plate end 3. is connected in double-edged fine-toothed comb following middle part 2. by rotating shaft, and can relatively rotate, and 6. spring is through rotating shaft and 5. goes up, and is supporting grate plate and 3. is being in the same place with double-edged fine-toothed comb is 2. identical.3. grate plate adopts corrosion-resistant, ageing-resistant light-duty hard material to make, and grate plate top 3. is a plurality of The shape bar, can keep and double-edged fine-toothed comb 2. The shape hole is complementary.7. 3. grate plate goes up keeps the big heap shape hole of little end opening suitable for reading in advance, 7. flows in the inlet for stom water by heap shape hole so that guarantee the rainwater of trace.5. rotating shaft is adopted with the 3. the same material of grate plate, and one end band silk can be gone up screw.The spring that 6. spring adopts resistant material to handle, its elastic force size is decided by grate plate own wt and downward initial streamflow experiment 3..

In Fig. 3, can be clear that comb circle 1., double-edged fine-toothed comb 2., the 3. mutual identical situation of three of grate plate.

In Fig. 4, can be clear that and comb circle 1., double-edged fine-toothed comb 2., grate plate is the mutual identical situation of three 3., simultaneously, can see that two grate plates each end 3. is by the 5. continuous situation of rotating shaft.

In Fig. 5, rotating shaft 5. pass double-edged fine-toothed comb 2. with two grate plates preformed hole 3. in, 6. spring is through rotating shaft and 5. goes up, and is supporting grate plate and 3. 2. coincideing with bamboo comb and be in the same place.This figure can help further to understand the structure of Fig. 2.
