Abstract

The utility model relates to an automatic closed-form manhole cover, which comprises a face covering, a plugging plate, a location column, a connection pole, a water storage basin, a support and a balance block, the water falling port of the face covering is connected movably with the clearance of plugging segment of the plugging plate, the water storage basin on one end of the plugging plate changes according to the water storage, changing the balance of the balance block, the plugging plate raising or dropping, the plugging segment closes or deviates from the water falling port, thereby, the utility model has dual-function of drain seeper on road and preventing mosquito and fly flying out to transfer sickness.

Description

Automatically closing inspection shaft lid

Technical field

The utility model relates to the special-purpose assorted device of sewer inlet for stom water, specifically is a kind of automatically closing inspection shaft lid.

Prior art

At present, the supporting inspection shaft of the inlet for stom water of sewer pipe covers its structure, and the drain gully on it is open.Therefore, there is following defective in practice: at first, therefore dropping to that dust on the road surface, sandstone and rubbish are not stoped useless (dirt) sewer pipe usually stops up sewer pipe, makes it lose the function of useless (dirt) water of discharging, torrential rain, sewage or waste water can overflow the road surface, and contaminated environment can become the river by ponding on the road surface, flood communal facility, even paralysed because of ponding in the city.Moreover be the mosquito that grows in useless (dirt) waterpipe, the insect of fly and other cockroaches is free to from the inlet for stom water turnover, and the infringement environmental sanitation is given birth to, harm people's health.According to relevant department's introduction, the sewage of city, rural area discharging is many at present, and underground useless (dirt) sewer pipe is also many, and mosquito, fly are also many, and contaminated environment and destruction people's quality of life is also quite serious.

Summary of the invention

In order to overcome the major defect that existing basement advances lid, the utility model provides a kind of automatically closing inspection shaft lid, helps protecting sanitation of environment, construction of modern civilized city.

The technical solution of the utility model mainly includes cover, plugging plate, reference column, connect post, water storage basin, pillar, counter-jib and balance weight, cover has drain gully, and plugging plate is equipped with stifled joint, reference column connects cover and plugging plate, the stifled joint of plugging plate connects with the drain gully of cover, connects post and connects plugging plate and water storage basin, and pillar connects cover peace weighing apparatus arm, counter-jib two connects balance weight respectively and connects post, and the bottom periphery of water storage basin is equipped with the gap.Whole automatically closing cellar for storing things well lid is seated in the inlet for stom water of sewer by the cover edge.

The counter-jib connecting struts of the utility model design, the water that its two has water storage basin and balance weight utilization to flow down from gap between drain gully and the stifled joint, change both weight ratios, the drive plugging plate descends, make the road surface rainwater flow into sewer pipe, it clears up, the water of water storage basin pours off through peripheral clearance, balance weight rises plugging plate, the stifled firm drain gully of stifled joint, make the cover drain gully with plugging plate stifled internode crack butt joint, help building the supporting sewer pipe function of raising modern city, can prevent effectively that rubbish and sandstone on the road surface from falling into useless (dirt) sewer pipe, avoid useless (dirt) water of line clogging and influence discharging, and mosquito and fly in (dirt) sewer pipe that prevents to give up enter the people living space.

Description of drawings

Fig. 1 is the utility model topology view.

The specific embodiment

Cover 1 rounded or rectangle or square of the present utility model, one group of strip-like-shaped or circular drain gully 8 are arranged above, look the cover size, drain gully 8 has 3-16 only (bar) approximately, the shape of drain gully 8 is back taper, end opening along greater than upper edge at 0.3cm, its bottom surface Luo Pattern connects the reference column 3 and the pillar 10 that is threaded, reference column 3 flexibly connects plugging plate 2, pillar 10 other ends are connected with the middle part of counter-jib 5, two of counter-jib 5 flexibly connects balance weight 7 by double-screw bolt or shaft lock respectively and connects the middle part of post 4, connect post 4 two spiral shell mosquito connection plugging plate 2 and water storage basin 6 respectively, be equipped with one group of its shape on the plugging plate 2, number and drain gully 8 corresponding stifled joints 9, the diameter of its upper surface or length are carried out the gap activity and are connected less than drain gully 8 upper edge diameters or length 0.2-0.4mm.Be equipped with gap 11 between the bottom surface of north water storage basin 6 and periphery, gap 11 is at 0.2-0.4cm, the diameter of water storage basin 6 or length are more than or equal to the alternate distance of 8 drain gullies on the cover 18, counter-jib 5 is 1: 1.5 with pillar 10 tie points and two with the distance that is connected that connects post 4 and balance weight 7, consults Fig. 1.Connect post 4 and add that water storage basin 6 adds the gross weight of plugging plate 2 and the weight ratio of balance weight 7 is 1: 2.It is fine; Balance weight 7 is raised water storage basin 6, and the stifled joint 9 of leak stopping piece 2 is connect with drain gully 8 gap-closings of cover 1 are stifled.Rainy day: the water on the road surface flows down from the drain gully 8 and the stifled gap of saving 9 of cover 1, wherein the water that flows down of 8 drain gullies 8 just flows in the water storage basin 6, water in the water storage basin 6 increases gradually, when connecing weight that post 4 and water storage basin 6 add water and surpassing balance weight 7 weight, water blockoff plate 2 and water storage basin 6 just drop to the position of 2a and 6a, balance weight 7 rises to the position of 7a, at this moment, block up joint 9 just with drain gully 8 complete leaving, to useless (dirt) sewer pipe, whole device is docked at the sewer inlet for stom water by the periphery of cover 1 to the water on road surface from drain gully 8 Channel Group.
