Abstract

The invention discloses a composite material closure gate which relates to the improvement of structures of sewage and wastewater collecting port devices. The composite material closure gate can be used for controlling sewage inlet quantity of a well body so as to prevent excessive sewage from centrally flowing into a treatment plant to cause that the treatment plant operates at an overload. The composite material closure gate comprises a well body arranged underground and communicated with a sewage pipeline, and also comprises a flap valve, an inhaul cable, a suspension pulley and a balance weight float bowl, wherein the flap valve is movably connected to a sewage pipeline port; the suspension pulley is arranged at the upper part of a well port in the well body; the inhaul cable is wound on the suspension pulley, one end of the inhaul cable is connected with the lower edge of the flap valve, and the other end of the inhaul cable is connected with the balance weight float bowl. The flap valve is arranged in the well body, thus the composite material closure gate has the function of preventing the excessive sewage from entering the pipeline. In the invention, the composite material closure gate is in an opening state under a normal condition, therefore, the balance weight float bowl in the opening state can be additionally provided. Under the normal condition, partial sanitary wastewater flows through in the well body and flows into a sewage treatment plant through the pipeline for central treatment.

Description

A kind of composite material door that dams
Technical field
The present invention relates to improvement dirty, waste water inlet apparatus structure.
Background technology
Along with the raising that urban environmental protection requires, Modern Urban Development be unable to do without urban drainage pipe network, and many environment-friendly types city has been set up outlet conduit separately to sewage and rainwater.But drainage pipeline networks often all can not in time discharge, shunt when running into sudden floods, causes a large amount of rainwater to flow into Sewage Plant, causes the Sewage Plant paralysis.Even can cause secondary pollution.
The mediation cut-off device of using in many catch-basins that dam, it generally all is flap valve, when rainwater is big, flap valve can not in time be closed, cause a large amount of rainwater and foreign material to flow into Sewage Plant, make sewerage treatment can't bear the heavy load, cause paralysis, bring significant impact for industrial production, people's lives and natural environment.
Summary of the invention
The present invention is directed to above problem, improved and a kind ofly can carry out the control of sewage inflow, flow into treatment plant, cause the door that dams of treatment plant's overload operation to avoid excessive sewage to concentrate to single well body.
Technical scheme of the present invention is: comprise the well body of being located at below ground and being communicated with sewage conduct, also comprise flap valve, drag-line, suspension pulley and counterweight floating drum; Described flap valve is movably connected in the soil pipe road junction; Described suspension pulley is located at well head top in the described well body; Described drag-line winding is on described suspension pulley, and an end of drag-line connects the lower edge of described flap valve, and the other end of drag-line connects described counterweight floating drum.Described counterweight floating drum hollow, the end face of counterweight floating drum is provided with water inlet.
The bottom of described counterweight floating drum is provided with the delivery port that is used to regulate the water yield in the floating drum.
The present invention is provided with flap valve in the well body, it self has and prevents that excessive water from entering the function of pipeline.But in the present invention program, normal condition needs it to be in opening, so the present invention has also set up and can make it be in the counterweight floating drum of opening.Under normal circumstances, there is the part daily life sewage to flow through in the well body, flows into Wastewater Treatment Plant, focus on by pipeline.Under the effect of counterweight floating drum weight, the door that dams is in opening, and sewage enters the pipeline flow-direction Sewage Plant by the door that dams, the ordinary water level 72 that dotted line shows among Fig. 1.When abnormal conditions such as occurring raining heavily, water level sharply raises in the well body, and the counterweight floating drum rises owing to buoyancy, and flap valve loses the active force of suspention and closes, and rainwater is then stopped by other pipelines and discharges in the well body, the anomalous sea level 71 of solid line demonstration among Fig. 1.

Fig. 2 is the structural representation of counterweight floating drum among the present invention
61 is hangers among the figure, the 62nd, and water inlet, the 63rd, delivery port.
Fig. 3 is the vertical view of Fig. 2
The specific embodiment
The present invention is as shown in Figure 1: comprise the well body 3 of being located at below ground and being communicated with sewage conduct 1, also comprise flap valve 2, drag-line 4, suspension pulley 5 and counterweight floating drum 6; Described flap valve 2 is movably connected in 1 mouthful of sewage conduct; Described suspension pulley 5 is located at well head top in the described well body 3; Described drag-line 4 windings are on described suspension pulley 5, and an end of drag-line 4 connects the lower edge of described flap valve 2, and the other end of drag-line 4 connects described counterweight floating drum 6.
Shown in Fig. 2,3, counterweight floating drum 6 hollows, the end face of counterweight floating drum 6 is provided with water inlet 62.And the hanger 61 that is used to connect drag-line.
The bottom of counterweight floating drum 6 is provided with the delivery port 63 that is used to regulate the water yield in the floating drum.
The door that dams of the present invention is on former flap valve basis, sets up the counterweight floating drum for glass fibre reinforced plastic check valve, uses stainless steel wire rope between the two, through the top Hanging roller, freely turns round, and through test, door closure opens and closes under floating drum control, freedom of movement, and resistance is very little.
Principle of the present invention is: under the normal condition (shown in ordinary water level among Fig. 1 72), the sewage draining exit flap valve in the catchpit is to open, and floss hole is normally closed.Various sewage flow to Sewage Plant by pipeline along the flap valve outlet, after Sewage Plant is handled, and discharging or reasonable the use.In case when summer rainwater was big, rainwater poured into catchpit suddenly, directly flows to Sewage Plant, this moment and counterweight floating drum after flap valve is connected, because the interior water level rising of well is risen, flap valve is closed gradually, water level is raised to certain altitude (shown in anomalous sea level among Fig. 1 71) flap valve and closes fully, this moment, rainwater no longer flowed to Sewage Plant, opened standby floss hole eliminating rainwater in the catchpit, when water level is stepped back, the counterweight floating drum descends, flap valve is opened voluntarily again, closes standby floss hole, normal circulation.
Generally speaking, rainwater pours into catchpit, and water level rises very fast, and therefore flap valve closes very soon, has only a small amount of rainwater to flow into sewage network, can not cause the Sewage Plant burden.
