Abstract

The utility model discloses a novel rain sewage buoyancy cut-off device which can fulfill the aim of cutting rain sewage off without external power and manual maintenance on the basis of fully utilizing the conventional rain sewage pipe network without large-scale reforming of the conventional rain sewage pipe network in an urban area. The novel rain sewage buoyancy cut-off device comprises a cut-off device base which is fixed in an accommodation and cut-off channel; a water outlet hole is formed in the base; a connection plate is fixed on the base through a shaft; a cut-off gate plate is fixed at one end of the connection plate, and a buoy is fixed at the other end of the connection plate; a positioning pin is arranged on the base; a positioning groove is formed on the connection plate; and the positioning pin is positioned in the positioning groove. On the basis of a principle of buoyancy, the aim of cutting the rain sewage off is fulfilled according to the height of a liquid level, the novel rain sewage buoyancy cut-off device can replace a gate, has a good cut-off effect, is applicable to cut-off of the rain sewage in a town rain sewage pipe network, and has a quite wide market prospect, the problem about fully-buried structure in the rain sewage pipe network is effectively solved, manual control, mechanical control and electric control are not required, and maintenance is not required.

Description

Novel rain sewage buoyancy guillotine

Technical field

The rain sewage that the utility model relates to avenue, integrated mill's rain sewage network dams; Particularly the rain sewage network to the city need not to carry out large-scale redevelopment; Making full use of on the basis of former rainy sewage network, need not external power and manual maintenance and promptly can realize the dam cut-off equipment of purpose of rain sewage.

Background technology

China is lack of water big country, and in addition along with the expanding economy environment pollution is more and more serious, particularly contaminated water source has arrived very serious stage, and the use contradiction of water resource is more and more outstanding, even interlocal water resource contention occurred.For this reason; Country has put into effect relevant laws and regulations with the protection water resource; Each cities and towns have all set up rainwater to collect pipe network, still, the most domestic city be with Storm Sewer Network and sewage network merging; Form the dirty interflow of present rain pipe network, all rainwater and sewage are all sent into Wastewater Treatment Plant handle.But so handle and just relate to following problem: 1, the dirty interflow of not all entering rain pipe network water all be sewage; All need handle; To not being that the rainwater of sewage handles is exactly a kind of waste; Increased processing cost, and will not be that rainwater and the sewage of sewage can descend the concentration of sewage when handling together and reduces treatment effect.2, the disposal ability of Wastewater Treatment Plant is limited, and disposal ability can't be caught up with emergent a large amount of rainfall sometimes, when the rainwater when torrential rain gets into Wastewater Treatment Plant, might cause Wastewater Treatment Plant's operation paralysis.For this reason, transform existing rain sewage network domestic many large-and-medium size cities, the rainwater that gets into the dirty interflow of rain pipe network is dammed with sewage separate, and only sewage is sent into Wastewater Treatment Plant and handle, and the rainwater that is not sewage is directly discharged.Existing rain sewage dams and generally adopts valve or gate to dam.Valve or gate all need manual work or electric power to carry out opening and closing, and running cost is than higher.

The utility model content

The utility model purpose is to overcome the deficiency of prior art; A kind of novel rain sewage buoyancy guillotine is provided, descends upstream or downstream in rain sewage buoyancy function, realize closure or openness through the floating drum that connects on the watertight shutter; Reach the effect of damming; Thereby the rainwater that will get into the dirty interflow of rain pipe network separates with sewage, only sewage is sent into Wastewater Treatment Plant and handles, and the rainwater that is not sewage is directly discharged; This device need not any manual work or electric power can be realized damming of rain sewage, need not any manual work or driven by power.

The technical scheme of the utility model is achieved in that

A kind of novel rain sewage buoyancy guillotine comprises being fixed on and receives the guillotine base that cuts canal, on said base, has weep hole; On said base, be fixed with junction plate through axle; It is characterized in that: be fixed with to dam at an end of said junction plate and use flashboard, its other end is fixed with floating drum, and said base is provided with alignment pin; Said junction plate is provided with locating slot, and said alignment pin is positioned at said locating slot.

The utility model compared with prior art has following advantage:

This device mainly utilizes the principle of buoyancy, and the height through liquid level is realized purpose that rain sewage is dammed can substituting gate.Efficiently solve complete buried structure in the rain sewage network.It dams effective, need not manual work, machinery, electric power control, is applicable to damming of cities and towns rain sewage network rain sewage, and does not need maintaining to have boundless market prospects.

Description of drawings

Fig. 1 is the structural representation of the said novel rain sewage buoyancy guillotine of the utility model;

1. 4. 5. alignment pins of base 2. flashboards, 3. junction plates, 6. locating slots 7. are received and are cut canal 8. floating drums 9. weep holes.

The specific embodiment

As can be seen from Figure 1, a kind of novel rain sewage buoyancy guillotine comprises being fixed on and receives the guillotine base 1 that cuts canal 7; On said base 1, have weep hole 9, on said base 1, be fixed with junction plate 3, it is characterized in that: be fixed with at an end of said junction plate 3 and dam with flashboard 2 through axle 4; Its other end is fixed with floating drum 8; Said base 1 is provided with alignment pin 5, and said junction plate 3 is provided with locating slot 6, and said alignment pin 5 is positioned at said locating slot 6.

As shown in Figure 1, guillotine is placed in the collection canal of the dirty pipe network of rain import department.The rain sewage quantity hour, the weep hole of guillotine is in opening, rain sewage sewage gets into pipe network through delivery port.In the time of in a large amount of rain sewage get into the collection canal, the water level of collecting in the canal is in propradation, along with the rising of water level; Floating drum rises under buoyancy function; The rotation of drive junction plate is closed weep hole with flashboard through damming, thus the purpose that the rain dirt is dammed in realization.This guillotine need not external plant equipment and power supply control can reach the effect that rain sewage is dammed.When inflow descends, receive the drawdown of cutting canal, floating drum is descending under the effect of gravity, and it is up to drive flashboard, and weep hole is opened, and along with the further decline of water level, flashboard continues up, up to weep hole is opened fully, thereby realizes a circulation.When a large amount of rain sewage arrives once more, repeat with cocycle.

More than show and described the advantage of basic principle, principal character and the wooden utility model of the utility model.The technician of the industry should understand; The new plough of this practicality is not restricted to the described embodiments; The principle of describing in the foregoing description and the manual that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
