Abstract

The utility model discloses an odor-proof draining grating for a street, which is composed of a water grating, a water tank and a valve sheet. The utility model is characterized in that the water grating is fixedly connected to the tank edge of the water tank; a relevant position on one side of the water tank is provided with an outflow opening which enables water to flow into a sewer; the included angle between the plane on which the opening is lied and the plane of an opening of the tank is an acute angle; the valve sheet is movably connected with the tank body at the upper part of the outflow opening, and forms a close over to the outflow opening under the action of gravity. When the cover of the valve sheet is closed, water can be drained, and odor, liquid, mosquitoes, maggots, etc. can be prevented from returning back to the ground so as to eliminate the contamination source in cities, which protects the sanitation of the environment and ensures people's physical and mental health.

Description

Road deodorization draining grate

The utility model relates to a kind of road draining grate, specifically a kind of only draining grate of valve that has back.

In the city, the rainwater that rains is by the draining grate that the road both sides are provided with rainwater to be entered in the sewer to drain.The draining grate of using is made up of housing and palisade bar now, places it in the outfall that puzzles in advance, and rainwater flows into sewer from the strip mouth that the palisade bar constitutes.Because sewer and the road external space are provided with packing device, can not stop back ground such as gas in the sewer, liquid.As gas with foreign flavor in the sewer and pernicious gas, colonize in mosquito maggot in the sewer pipe chamber etc. and all can go on the ground, enter the space, urban district, thereby cause environment pollution, bring worry to daily life, harm people's physical and mental health.Particularly when the channel jam of sewer, sewage can return on the road and pollute the environment equally, influences city look and feel.

In order to solve the deficiencies in the prior art, the purpose of this utility model provides a kind of road deodorization draining grate, can prevent after the installation that foul smell, mosquito maggot and sewage in the sewer from entering the space, urban district and go on the ground, protected environment.

In order to realize the purpose of this utility model, its technical scheme of specifically taking is: this draining grate constitutes by having water grate that bar hole can leak and the special-shaped tank that can catchment and the valve block of groove side thereof; Tank upper end outer perimeter has the groove edge that can connect firmly the water grate its upper surface, and there is a flow export of being convenient to liquid inflow sewer in the cell body at recessed position, cell wall one side relevant position, and the angle α on plane, place, this mouthful outer end and tank mouth plane is an acute angle; Described valve block and flow export upper slot body wall be movable connects and under its self-gravity action to flow export formation capping, thereby prevent backspace ground such as foul smell, liquid in the sewer.

The utility model road deodorization draining grate connects firmly a catch basin below prior art draining grate; the respective side of tank has flow export; when having flowing water, the flow export capping can open; flow through the back by its valve block lid from the gravity closing flow export; thereby prevent that gas with foreign flavor and pernicious gas and ducted mosquito maggot etc. in the sewer from entering the space, urban district; sewage turns back to the road surface in the time of also can preventing the sewer obstruction; thereby stink and pollution sources have been eliminated; protect the city sanitation of environment, guaranteed people's physical and mental health.

Be described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a sectional drawing of the present utility model.

Fig. 2 is that the A of the utility model Fig. 1 is to view.

In the accompanying drawings, the tank 4 of long utility model road deodorization draining grate is special-shaped groove shape, its the upper end outer perimeter be provided with have certain width groove along 12, groove is along equidistant being provided with perpendicular to the ladder unthreaded hole of groove along last plane on 12, the bottom surface of tank from after have the outflow that certain slope is beneficial to water forward.Tank 4 is made of preceding tank 4.1, middle tank 4.2, the back tank 4.3 of band overlap joint mouth 9, can remove middle tank 4.2 or add the length that tank is regulated tank in the joint according to on-the-spot needs.Recessed position, the end socket sidewall relevant position of preceding tank 4.1 is provided with a flow export 13, makes the liquid that flows in the groove flow into sewer well; And the angle α on the plane at place, flow export 13 outer end and tank mouth plane is an acute angle, and the angle at this angle is preferably spent less than 90 greater than 45 degree; The external wall of flow export 13 upper slots is provided with centre two a solid ear 2 with holes of certain distance, inserts bearing pin 3 in this earhole valve block 1 activity is connected on the cell wall.The area of described valve block 1 is obturaged flow export from gravity greater than flow export 13 and by it, when the water in the groove flows into sewer, the impulse force of water is opened valve block 1, and valve block 1 is obturaged flow export by its gravity return when anhydrous, prevents that gas, liquid and the mosquito maggot etc. in the sewer from returning on the ground.The antirust plastic covering 5 of the different color that strip mouth 7 that water grate 10 forms by grate frame 6 with by the grate frame and grate frame thereof are outer constitutes; On the periphery of grate frame 6 equidistant be provided with perpendicular to the frame bottom surface with tank along the corresponding screw blind hole of glazing centerline hole.Water grate 10 places the groove of tank 4 along being fixed as one on 12 and by countersunk head screw 8.This road deodorization draining grate places in the outfall that puzzles in advance, and rainwater flows in the tank from the strip mouth and flows into sewer by the flowing water mouth on the cell wall, by valve block the flow export outside is shut things such as the gas in the sewer, liquid are enclosed in the water channel.
