Abstract

The utility model is a deodorization, theftproof and filtering device used for the all-automatic public sewer port, which belongs to the device used at the public sewer port, and is used to automatically seal the fall channel port, meanwhile the pollution discharge function will not be affected, the utility model mainly consists of a fall grate and the fall channel, and is characterized in that the water outlet at the bottom part of the fall channel is provided with a ball float, the ball float can seal the port of the fall channel, and isolate the channel of the sewer to the road surface, then bad smell in the sewer can not spread to the road surface, then the urban air environment is effectively protected. When discharging the water, the ball float automatically floats off under the water buoyancy function, then the water outlet is opened for completing the discharging function. The utility model has strong filtering function, simple and practical structure, convenient installation and smooth discharging effect, and can fully replace the sewer cover plate and the fall grate in the present cities. The utility model is the environment-friendly and pollution-free public sewer port, and has functions of deodorization, theftproof and pollution prevention.

Description

A kind of full-automatic common sewer mouth deodorization, antitheft, filter

Technical field the utility model belongs to the common sewer device, particularly a kind of deodorization, antitheft, antipollution common sewer delivery port.

Background technology all is distributed with various sewer mouths at city square or both sides, street, is used for discharging municipal sewage or rainwater to being positioned at underground sewer.Sewer mouth in the city generally all is to adopt cover plate or drainage grate now, because drainage grate directly communicates with sewer, make the sewage in the sewer outwards to distribute foul smell by the sewer mouth, not only pollute urban air, and the civic physical and mental health also had very big influence, belong to non-environmentally friendly machine.

The summary of the invention the purpose of this utility model is to provide a kind of can close drowning road junction automatically, and don't influences the full-automatic common sewer mouth deodorization of normal drain function, antitheft, filter.The utility model adopts following technical proposals for this reason: a kind of full-automatic common sewer mouth deodorization, antitheft, filter, mainly form by the drainage grate that has water falling hole, the road that falls into water, drowning road communicates with above-mentioned water falling hole, on drainage grate, be provided with the openable pilferproof closure that has theftproof lock, it is characterized in that: the bottom in the road that falls into water is provided with a delivery port, is provided with a ball float at the delivery port place.After the utility model adopts above structure, owing to set up a ball float at the delivery port place, this ball float closes delivery port at ordinary times, the passage that has completely cut off sewer and road surface, make the foul smell in the sewer not distribute to the road surface, avoided the excessive of the interior foul smell of sewer, guaranteed that the city air is not subjected to the pollution of foul smell in the sewer.When draining, ball float will float under the effect of water, thereby opens delivery port, does not influence normal drain function, the draining smoothness.After draining finished, ball float automatically reset.Filter frame in the road that falls into water can effectively be collected impurity and the dirt that falls, and has avoided impurity and dirt to fall in the sewer, has guaranteed the unimpeded of sewer.Have the effect that filtering function is strong, simple and practical, easy for installation, draining is smooth, can substitute existing incity, city sewer cover plate and drainage grate fully, be the nuisanceless common sewer mouth of a kind of environment-friendly type filter, deodorization, antitheft, anti-pollution.

Description of drawings Fig. 1 is a kind of structural representation of the present utility model, and Fig. 2 is the structural representation of drainage grate shown in Figure 1, and Fig. 3 is the structural representation of drainage grate shown in Figure 1.

In the specific embodiment accompanying drawing, 1 is that drainage grate, 2 is that drowning road, 3 is that ball float, 4 is that water falling hole, 5 is delivery port.As shown in drawings, the utility model mainly is made up of the drainage grate 1 that has water falling hole 4, the road 2 that falls into water, and water falling hole 4 can be positioned at the top of drainage grate 1, also can be positioned at the sidepiece of drainage grate 1.This drainage grate 1 be designed to the common sewer mouth adapt circular or square, on drainage grate 1, be provided with the openable pilferproof closure that has theftproof lock.The bottom that road 2 is positioned at drainage grate 1 of falling into water communicates with above-mentioned water falling hole 4, can adopt hasp type to connect between drowning road 2 and the drainage grate 1.Below drainage grate 1, be provided with turning-in have groove on the attacker, also be provided with on the road 2 that falls into water with above-mentioned on the corresponding bandy attacker down of attacker, last attacker, the attacker can be interlocked fully down, makes drainage grate 1 and drowning road 2 formation one.Bottom in the road 2 that falls into water is provided with a delivery port 5, is provided with a ball float 3 at delivery port 5 places.Hungry area system ball or baton round in this ball float 3 can adopt.

The bottom design in above-mentioned drowning road 2 is high around being, middle low.Be beneficial to ball float 3 and be positioned at delivery port 5 places, be beneficial to the discharge of sewage simultaneously.Top in the road 2 that falls into water is provided with filter frame, is used to collect the impurity dirt that falls from drainage grate 1.

Under normal condition, ball float 3 is positioned at delivery port 5 places, closes delivery port 5, thus the passage on isolated sewer and road surface.When drainage grate 1 falls sewage,, carry out normal draining because buoyancy of water holds up ball float 3, thereby opens delivery port 5.After sewage had been arranged, ball float 3 was got back to delivery port 5 places automatically by own wt.
