Abstract

This utility model discloses a well cover device used in sewer, including a well cover of a clogging sewer outlet. Several holes for discharging water are arranged on the well cover. The water distribution device also include the a well cover sheath which is arranged in the sewer outlet and is correspondent with the well cover, and a water chamber whose inlet towards to the sewer is positioned in the lower part of well cover in the well cover sheath. The well cover is provided with some water distribution device that is communicated with the water distribution holes and the bottom of inside space of the water chamber. This utility model is capable of preventing effectively the polluted gas in sewer pipes overflowing while discharging the sewerage and seeper on ground, thus avoiding the environment to be polluted and ensuring people's health.

Description

The sewer manhole lid device

Technical field

The utility model relates to a kind of sewage discharge device of avenue, especially a kind of sewer manhole lid device that can draining can prevent the dusty gas in the sewer to the external environment condition diffusion again.

Background technology

Mostly the flood control blowdown of avenue is to adopt sewer to realize, and the used well lid of capping sewer mouth mostly is the formula well lid, both on well lid, be provided with many drainage holes, and by drainage hole ground rainwater or sewage flowed in the sewer and by drainage pipe by drainage hole and drain.But when not having ponding on ground, the gas that sewage distributed in the sewer will overflow by the drainage hole on the well lid and be dispersed in the outside air environment, owing to be mixed with from hospital in the sewage in the sewer, the sewage of family life, even might be mixed with the industrial wastewater of enterprise, therefore the smell that distributes has not only polluted the air outside environment, make street pedestrian and overlooking and people that occupy feel to stimulate unpleasant, suffer untold misery, and sewage can contain a large amount of germs, virus, these germs, virus just might emission gases drainage hole by well lid distribute in the outside air, the healthy of people worked the mischief.

Summary of the invention

Technical problem to be solved in the utility model has provided a kind of sewer manhole lid device; it can be in the sewage ponding of draining ground; effectively prevent the overflowing of dusty gas in the sewer pipe, protected environment not contaminated, ensured that people's is healthy.

For solving the problems of the technologies described above, the technical solution of the utility model is: the sewer manhole lid device, but the well lid that comprises shutoff sewer mouth, well lid is provided with some drainage holes, described sewer manhole lid device also comprises and is arranged on sewer mouth and the corresponding well lid cover of well lid, well lid puts the below that is positioned at well lid and is provided with the reservoir that is opened on sewer, and described well lid is provided with the water guider that is communicated with drainage hole and reservoir intracavity bottom.

As a kind of improvement, described reservoir is along the circumferential extension of whole sewer inner surface, and described drainage hole is located at all sides of well lid, and described water guider comprises that the bottom surface of well lid is positioned at the next door that the inboard of drainage hole is provided with, and the bottom of reservoir inner chamber is inserted in the next door.

As further improvement, described well lid is a round manhole cover.

As further improvement, described well lid is the rectangle well lid.

Owing to adopted the sewer manhole lid device of said structure; by the well lid that is arranged on the sewer mouth reservoir that puts and the water guider that is communicated with drainage hole and reservoir intracavity bottom; when the draining of this device busy; ground sewage will enter in the reservoir through water guider by drainage hole; and be discharged in the sewer by reservoir; and when the not draining of this sewer manhole lid device; will sewer and external environment condition be separated by the water in the reservoir; avoided overflowing of the interior dusty gas of sewer; thereby protected environment, protected that people's is healthy.The water guider that the next door of the insertion reservoir bottom that employing is provided with along the bottom surface of the reservoir of the circumferential extension of whole sewer inner surface and well lid constitutes has not only been simplified the structure of whole manhole lid device, has also improved its drainability.

Description of drawings

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further.

Fig. 1 is a sewer manhole lid device structural representation of the present utility model;

Fig. 2 is the structural representation of sewer manhole lid device well lid one embodiment of the present utility model;

Fig. 3 is the structural representation of another embodiment of sewer manhole lid device well lid of the present utility model.

The specific embodiment

According to shown in Figure 1, sewer manhole lid device of the present utility model is: comprise the well lid 1 that can be used for shutoff sewer mouth, on well lid 1, be provided with several drainage holes 11, on the sewer mouth, be provided with well lid cover 2, well lid cover 2 is corresponding with well lid 1, like this, when shutoff sewer mouth, support well lid 1 by well lid cover 2; Be positioned on the well lid cover 2 well lid 1 below be provided with reservoir 21, reservoir 21 is opened in the sewer, and, the opening of reservoir 21 can be located at the top of reservoir 21 in order to make water that reservoir 21 can deposit capacity to realize this sewer manhole lid device sealing function.On well lid 1, be provided with the water guider that is communicated with drainage hole 11 and reservoir 21 intracavity bottoms, this water guider can be an aqueduct, but in order to simplify the structure of this manhole lid device, reservoir 21 can be designed to along the reservoir of the circumferential extension of the inner surface of whole sewer, and drainage hole 11 is located at all sides on the well lid 1, water guider then can be designed to be positioned in the bottom surface of well lid 1 next door 12 that the inboard of drainage hole 11 is provided with, next door 12 inserted the inner chamber of reservoirs 21 and extend to the bottom of reservoir 21 inner chambers, by next door 12 reservoir 21 is divided into two parts that intracavity bottom is communicated with, like this, when the inner contain water of reservoir 21, the passage that is positioned at reservoir 21 intracavity bottoms will be covered by water, thereby sewer is separated with extraneous, when not draining, by the sealing function of the water in the reservoir 21, prevented that overflowing of sewer internal contamination gas from distributing; And when using this sewer manhole lid device to carry out draining, ground sewage enters into the inner chamber that is arranged in next door 12 1 sides in the reservoir 21 via drainage hole 11, and the passage by being positioned at reservoir 21 bottoms enters sewer via the inner chamber of the reservoir 21 of country fair next door, position 12 opposite sides by opening, realizes its dirt eliminating function.

In order to improve this sewer manhole lid device practicality, well lid 1 can be designed to rectangle as shown in Figure 2, also can be designed to circle as shown in Figure 3.And in the application of reality, well lid can be overlapped 2 and be designed to steel concrete, well lid then can adopt cast iron materials, and well lid can be overlapped 2 and be solidified as a whole with sewer, also well lid 1, well lid cover 2 and sewer can be solidified as a whole, to improve theftproof performance.
