Description

Fish belly type adjustable weir

Technical Field

The utility model relates to an urban sewage administers technical field, in particular to adjustable weir of fish belly formula.

Background

A large number of sewage discharge pipelines are laid underground in cities, and a combined intercepting well or a split intercepting well facility is usually built at the joint of the sewage discharge pipelines. Through the diversion and guiding effects of the intercepting wells, sewage can be guided to a sewage treatment plant or an external river channel.

When rainy season, along with the abundant inflow sewage discharge pipeline of rainwater, and then make the water level in the underground pipe network rise by a wide margin, because sewage treatment plant's sewage treatment ability is limited, at this moment can generally turn down the flow control valve of sewage treatment plant inlet tube department, and then the restriction is gone to sewage treatment plant's water yield, in letting the rainwater directly discharge into outer river course along with sewage pipeline to guarantee that the underground pipe network water level can not continuously rise and then lead to urban waterlogging.

However, when entering a non-rainy season or a flood occurs, the water level in the urban underground pipe network is relatively low and the water level in the outer river channel is raised, and it is necessary to close the sewage conduit communicating with the outer river channel to prevent river water from being poured into the sewage conduit and to introduce sewage into the sewage treatment plant for sewage treatment.

In order to achieve the purpose, sewage treatment equipment is needed, the water level is mostly monitored through a sensor in the existing means, and the pipeline valve is manually controlled to be opened or closed according to the water quantity.

SUMMERY OF THE UTILITY MODEL

The utility model aims at: the fish belly type adjustable weir can automatically realize drainage control of a sewage pipeline without manual control, automatically opens a sewage pipe communicated with an outer river channel to discharge sewage into the outer river channel in rainy seasons, and closes the sewage pipe communicated with the outer river channel to prevent river water from flowing into a sewage pipe network in non-rainy seasons.

The utility model provides a technical scheme that its technical problem adopted is:

a fish belly type adjustable weir comprises a mounting bracket fixed at the top of a concrete weir and an upper sealing plate component fixed at the top of a sewage outlet; a bearing bracket is fixed on the mounting bracket, and a bearing is arranged on the bearing bracket; the bearing is fixed with a fish belly weir plate and two side sealing plate assemblies, and the two side sealing plate assemblies are respectively arranged on two sides of the fish belly weir plate.

As a further preferable technical solution, the upper sealing plate assembly includes a bent piece and holding brackets fixed to both ends of the bent piece.

As a further preferred technical scheme, the bending piece comprises a fixing plate and a bottom plate, and an included angle of 95 degrees is formed between the fixing plate and the bottom plate.

As a further preferred technical scheme, the middle part of the plate body of the fish belly type weir plate is provided with a cambered surface cavity.

As a further preferable technical scheme, a sealing baffle plate is arranged at the top of the plate body of the fish belly type weir plate.

As a further preferred solution, the side sealing plate assembly comprises a sector panel, and sealing guard plates are mounted on both straight edges of the sector panel.

As a further preferable technical scheme, the left end and the right end of the inner side of the plate body of the fish belly type weir plate are respectively provided with a sealing rubber strip.

The utility model has the advantages that: the utility model is easy to be reformed and implemented, and has no requirement on the foundation structure at the bottom of the sewage pipeline; need not manual control in the use, can realize the drainage control to sewage pipe automatically, open automatically and outer river way intercommunication sewage pipe when rainy season with sewage discharge to outer river way in, when non-rainy season, close and outer river way intercommunication sewage pipe prevents that river water from flowing into sewage pipe network.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-3, the fish belly type adjustable weir comprises an upper part and a lower part; wherein, the upper part is an upper sealing plate component 1 which is fixed on the top of the sewage outlet 8; the lower part of the fish-bellied adjustable weir is fixed on the top of the concrete weir 9 at the sewage outlet.

Wherein, the upper sealing plate component 2 comprises a bending component, and the bending component comprises a fixing plate 21 and a bottom plate 22; and an included angle of 95 degrees is formed between the fixing plate 21 and the bottom plate 22.

And two ends of the bending piece are respectively and fixedly provided with a retaining bracket 23.

Wherein the lower part of the fish belly type adjustable weir is fixed at the bottom of the pipe wall of the sewage pipeline 8 through a mounting bracket 1. A bearing bracket 3 is mounted on the mounting bracket 1, and a bearing 4 is mounted on the bearing bracket 3, the bearing 4 being rotatable on the bearing bracket 3.

The fish belly weir plate 5 is fixed on the bearing 4. As shown in fig. 1, a cambered cavity 51 is arranged in the middle of the plate body of the fish belly type weir plate 5; a sealing baffle plate 52 is arranged on the top of the plate body of the fish belly type weir plate 5.

Wherein, the fish belly weir plate 5 can rotate together with the bearing 4, and when the fish belly weir plate 5 rises to the highest point, the sealing baffle plate 52 is directly contacted with the bottom plate of the upper sealing plate assembly 2.

In addition, in order to enhance the sealing effect, sealing rubber strips 7 are respectively arranged at the left end and the right end of the inner side of the plate body of the fish belly type weir plate.

Further, a side seal plate assembly 6 is fixed to each side of the bearing 4. As shown in fig. 3, the side sealing plate assembly 6 includes a sector plate 61, and sealing plates 62 are mounted on both straight edges of the sector plate 61.

In the scheme, a plurality of sealing assemblies are arranged, and the sealing position is ensured to be watertight through contact with the sealing assemblies.

The working process of the utility model is as follows:

in non-rainy seasons, the water level of the urban pipe network is relatively low, and all sewage flowing into the interception well enters the sewage pipe and goes to the sewage treatment plant. If the water level of the external river is relatively high, the fish belly type adjustable weir can float upwards under the action of external river water, so that the external river water cannot enter the water inlet pipe and the sewage pipe. The utility model discloses be used in under this circumstances can the four sides stagnant water when it floats to the highest position.

In rainy season, the water flow of the water inlet pipe is large, and the water inflow amount usually exceeds the treatment capacity of a sewage treatment plant. At the moment, the flow area of the flow regulating valve at the sewage pipe opening is reduced to control the water inflow of the sewage pipe, so that the water level inside the fish belly type adjustable weir can be increased. At the moment, the raised water level breaks the state in non-rainy seasons, the weir plate is put down, and the water on the inner side is discharged to the river channel. So as to ensure that the water level of the pipe network cannot be continuously raised and further cause urban waterlogging.
