Technical Field

[0001] The utility model belongs to the technical field of hydraulic self-adjusting sewage interception, and particularly relates to a hydraulic self-adjusting sewage interception restrictor. Background Technique

[0002] The sewage interception well is used for combined sewers. Before the rainwater and sewage are separated, it ensures that the dry-season sewage enters the sewage treatment plant and does not flow into the river. During the rainy season, it can intercept part of the initial rainwater to reduce the overflow pollution. Thus, it protects the environment and water quality. The sewage interception well can intercept the dry-flow sewage and the initial rainwater into the sewage pipe network system and incorporate them into the urban sewage collection and treatment system. This method makes full use of the original pipeline, avoids a large amount of complex work, and reduces the construction of urban sewage pipes.

[0003] In the existing related technologies, for the self-adjusting sewage interception restrictor, when the rainwater is in a flowing state in the well body of the rainwater pipe sewage interception well and the rainwater impacts the floating barrel, the connecting ring may shake left and right, and it is impossible to effectively ensure the control of the sewage inlet concentration. Therefore, it is urgent to design a hydraulic self-adjusting sewage interception restrictor to solve these problems. Content of the Utility Model

[0027] Refer to Figures 1-6 , an embodiment provided by the present invention: a hydraulic self-adjusting sewage interception and flow limiter, including an interception well body 1, an auxiliary mechanism 2 is arranged on the interception well body 1, and an automatic sewage interception mechanism 3 is arranged inside the interception well body 1.

[0028] In this embodiment: The auxiliary mechanism 2 includes a bearing assembly disposed on the sewage interception well body 1. A grating plate assembly is installed on the bearing assembly. A sewage interception pipe 206 is installed on one side of the sewage interception well body 1. An inclined plate 208 is installed in the sewage interception well body 1. The bearing assembly includes a first bearing plate 203 disposed on the sewage interception well body 1. An installation groove 204 is provided on the first bearing plate 203. The grating plate assembly includes a connecting platform 202 disposed in the bearing assembly. The installation groove 204 and the connecting platform 202 are connected by a rotating pin shaft. A grating plate 201 is installed on the connecting platform 202. Through plate grooves 205 are arranged at equal intervals horizontally on the grating plate 201.

[0029] In this embodiment: The automatic sewage interception mechanism 3 includes a guide plate 301 disposed in the sewage interception well body 1. A second bearing platform 302 is installed on the guide plate 301. A rotating shaft 303 is longitudinally installed on the second bearing platform 302. A rope 304 is disposed on the outer surface of the rotating shaft 303. A floating cylinder 305 is installed at one end of the rope 304. The rope 304 and the floating cylinder 305 are fixedly connected. A lifting gate plate assembly is installed at the other end of the rope 304. A moving limit cylinder assembly is disposed on the outer surface of the rope 304. A guiding square platform 307 is horizontally arranged on the second bearing platform 302. A rectangular groove 308 is installed on the guide plate 301. A placing platform 310 is disposed below the floating cylinder 305. An elastic pushing plate 311 is disposed below the placing platform 310. A telescopic hydraulic cylinder 312 is installed on one side of the elastic pushing plate 311. The moving limit cylinder assembly includes a limit cylinder 3061 disposed on the outer surface of the rope 304. An electric hydraulic cylinder 306 is disposed on one side of the limit cylinder 3061. The limit cylinder 3061 is a hollow cylinder. The moving limit cylinder assembly is used for tensioning, guiding and limiting the rope 304. The limit cylinder 3061 and the rope 304 are coaxial when stationary. The lifting gate plate assembly includes a gate plate 309 disposed at the other end of the rope 304. A guide groove 3091 is vertically arranged on the gate plate 309. The rectangular groove 308 and the guide groove 3091 are slidably connected.

[0030] Working principle: When in use, when it rains, the water level in the rainwater pipe gradually rises, causing the buoy 305 to rise under the buoyancy of water. The sluice gate 309 gradually descends under the action of the downward resultant force. When the buoy 305 rises and enters below the limit cylinder 3061, at this time, the sluice gate 309 gradually closes the sewage interception port of the sewage interception pipe 206, preventing a large amount of clean water from being discharged into the sewage interception pipe 206. Since the concentration of pollutants in the initial rainwater is relatively high, at this time, by starting the electric hydraulic cylinder 306 to drive the limit cylinder 3061 to push out a certain distance, at the same time, the frictional force caused by the included angle between the resultant force direction vertical due to gravity and buoyancy between the limit cylinder 3061, the rope 304 and the buoy 305 increases, thereby reducing the descending speed of the sluice gate 309 in the rectangular groove 308 and slowly closing the orifice of the sewage interception pipe 206; when the rainfall is too large, the rainwater pushes the buoy 305 to rise, the sluice gate 309 shields the sewage interception pipe 206, and the water levels in the rainwater pipe and the sewage interception well body 1 gradually decrease. Start the electric hydraulic cylinder 306 to drive the limit cylinder 3061 to gradually retract and lower the rope 304 and the buoy 305, reducing the entry of rainwater with good quality in the later stage of heavy rain into the sewage pipe, improving the sewage interception effect and reducing the operating cost of the sewage system.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
