Description
Technical Field
The utility model relates to an urban rain sewage treatment equipment technical field, in particular to prevent flowing backward and use fish belly weir.
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 guide effect of the intercepting wells, the rainwater and sewage can be guided to a sewage treatment plant or an external river channel.
In dry seasons, urban sewer sewage can be discharged into river channels after being treated, and in order to achieve the purpose, sewage treatment equipment is needed. However, when the flood season comes, the water level in the river channel rises, and then river water enters the urban underground pipeline network through the external discharge port, so that the urban waterlogging is caused.
At present, the water level is monitored through a sensor in most existing means, and the pipeline valve is controlled to be opened or closed manually according to the water quantity, however, the equipment is high in cost, later maintenance is troublesome, the maintenance cost is high, the service life is short, and the burden of urban sewage treatment is increased. Therefore, the inventor designs a fish belly type adjustable weir (patent number: 201922075275.2), the weir plate with a float bowl is arranged on the device, when the water level of the outer river channel rises, the weir plate can be automatically closed along with the rise of the water level, so that the backflow can be prevented, and when the water level of the outer river channel falls, the weir plate can be automatically opened, so that the urban sewage can be smoothly discharged into the river channel. The equipment is also suitable for the reconstruction of various old wells.
However, this prior fish belly type adjustable weir structure is not perfect, especially in its sealing structure. When the weir plate of the prior fish belly type adjustable weir is closed, the sealing of the two sides and the bottom of the weir plate is realized by extruding the sealing strips on the two sides of the weir plate and the plate surface of the side plate. After the sealing mode is used for a period of time, the gap between the side plate and the weir plate sealing strip is increased along with the aging of the sealing strip material, so that the water leakage phenomenon occurs. In addition, the sealing method has high requirements on the sealing strip material, and if a common sealing material is adopted, when the water pressure of an external river is too high, the sealing strip still deforms under the action of strong pressure, so that the water leakage phenomenon occurs.

A weir plate limiting plate 7 is fixed at the bottom of the two side plates 5, and the weir plate limiting plate 7 is positioned between the left side plate and the right side plate and is fixedly connected with the left side plate and the right side plate.
In addition, a weir plate sealing structure is arranged at the edge of the inner side surface of the weir plate 2, and the weir plate sealing structure comprises a weir plate sealing frame 21 and a weir plate sealing strip 22 as shown in fig. 5; the weir plate sealing frame 21 is fixed on the weir plate 2, and the weir plate sealing strip 22 is fixed in the weir plate sealing frame 21. When the slice 2 is completely closed, the slice sealing strip 22 is completely attached to the sealing expansion edge of the wedge frame 1, thereby playing a sealing role.
The specific structure of the hinge mechanism 3 is shown in fig. 6, and includes a first fixed seat 31, a second fixed seat 32 and a connecting rod 33; the first fixed seat 31 is fixed on the fixed expansion edge 11 of the wedge-shaped frame; the second fixing base 32 is fixed at the bottom of the outer side surface of the weir plate 2, one end of the connecting rod 33 is connected with the first fixing base 31 through a rotating shaft, and the other end of the connecting rod is connected with the second fixing base 32 through a rotating shaft.
The weir plate adjusting mechanism 6 comprises an adjusting screw 61, a fixing nut 63 and a locking nut 62; the fixed nut 63 is fixed on the connecting rod 33 of the hinge mechanism 3, and the adjusting screw 61 sequentially passes through the locking nut 62 and the fixed nut 63 to be abutted against the outer wall of the weir plate 2. During equipment debugging, through adjusting screw, can adjust the face gradient of weir plate to ensure sealing strip and wedge frame in close contact with, improve sealed effect.
The utility model discloses a theory of operation:
in dry seasons, the water level of the external river channel is low, the weir plates 2 are always in an open state, as shown in fig. 1 and 3, rainwater in the urban underground pipe network can be discharged into the external river channel through the fish belly weir.
When rainy season or flood season come, outside river course water level risees, and along with the rising of water level, flotation pontoon 4 drives the weir plate and rotates, constantly rises, finally can close weir plate 2 completely to prevent that the water in outer river course from pouring into in the city underground pipe network, cause the urban waterlogging.
The biggest difference of this scheme and traditional scheme lies in that the weir plate seal structure of this scheme is located the weir plate medial surface, and not the side of controlling about the weir plate about. When traditional seal structure outside river course water pressure was too big, the phenomenon of seepage can take place for both sides and bottom, and along with the wearing and tearing of both sides sealing strip or ageing, also can lose sealed effect, and seal structure in this scheme is along with outside hydraulic increase, and the weir plate sealing strip then extrudees tighter with sealed expansion limit, and sealed effect is then better. And in the daily lifting process of the weir plate, the weir plate sealing strip and the sealing expansion edge can not be contacted and rubbed, so that the service life of the weir plate sealing strip can be greatly prolonged, and the later maintenance cost is reduced. In addition, the sealing effect of the weir plate can be adjusted through the weir plate adjusting mechanism, so that the best effect is achieved.
