Examples

As shown in fig. 1-3, the present embodiment provides a technical solution: a drainage pipeline for municipal works comprises two adjacent pipelines which are arranged in a roadbed 1, an inspection well is arranged on the roadbed 1, an inspection well cover 2 is arranged at the opening part of the inspection well, the two pipelines are respectively defined as a first pipeline 10 and asecond pipeline 11, opposite ends of the first pipeline 10 and thesecond pipeline 11 are communicated with a transition pipe 9, acommunication bin 8 is communicated with the transition pipe 9, a water storage bin 3 is communicated with thecommunication bin 8, the water storage bin 3 is arranged in an inspection well, the outer wall of the water storage bin 3 is in abutting connection with the inner wall of the inspection well, the connection surface of the water storage bin and the inner wall of the inspection well has a sealing effect so as to ensure that rainwater in the inspection well can be discharged into the communication bin from the water storage bin, a filter screen 6 which can freely turn over up and down is hinged on the inner wall of thecommunication bin 8, the filter screen 6 buffers the downward swinging of the filter screen 6 by a buffer unit, the buffer unit comprises a fixed arm 7 which is arranged on one side of the filter screen 6 facing upwards, a connectingpost 4 is hinged on the inner wall of the water storage bin 3, atelescopic post 5 is hinged on the fixing arm 7, thetelescopic post 5 coaxially slides and penetrates into the connectingpost 4, one end of the telescopic post penetrating into the connectingpost 4 is sleeved with afloating block 12, a throughgroove 13 allowing thefloating block 12 to move and freely pass is formed in the connectingpost 4, aspring 14 sleeved on thetelescopic post 5 is arranged in the throughgroove 13, thespring 14 elastically abuts against thefloating block 12, when the rainfall is normal, the elastic abutting force of the spring on the floating block can drive the filter screen to upwards overturn along the hinged position with the water storage bin, so that rainwater enters the water storage bin and can be filtered by the filter screen, small foreign matters and impurities which cannot be filtered by a water leakage groove on the inspection well cover can be filtered by the filter screen, the filtered rainwater enters a drainage pipeline, but when waterlogging occurs in cities, the drainage pipeline is firstly ensured to be quickly drained, at this moment, a large amount of rainwater enters the inspection well, impact is generated on the filter screen, the impact force is greater than the elastic propping force of the spring to the floating block, the filter screen can be rapidly turned downwards along the hinged position of the inner wall of the water storage bin, after the filter screen is turned downwards, the speed of rainwater entering the transition pipe is increased, and thus the drainage capacity of the drainage pipe is rapidly recovered under the condition that the urban water logging is generated, so that the drainage efficiency of the urban drainage system is improved.

The end of thetelescopic column 5 adjacent to thefloating block 12 is coaxially and fixedly connected with apull rod 19, one end of thepull rod 19 far away from thetelescopic column 5 is sleeved with apress block 17, an empty avoidinggroove 16 allowing thepress block 17 to move freely is formed in the connectingcolumn 4, afixing ring 15 is arranged in the empty avoidinggroove 16, a through hole allowing thepull rod 19 to freely pass through is formed in thefixing ring 15, apressure sensor 18 is arranged on one surface of thefixing ring 15 facing thepress block 17, when the filter screen is rapidly turned downwards, the pull rod is driven to move downwards, the press block moves downwards until the press block abuts against the pressure sensor, the pressure sensor generates a pressure signal, the pressure signal is transmitted to an external cloud management department through a wireless transmission module (the wireless transmission module is of the prior art and is not accumulated again) arranged in the empty avoiding groove, the cloud management department judges that the rainfall of an inspection well corresponding to the pressure sensor is large, or the drainage pressure is large, and the management department needs to perform quick response, and thus the management capability of the management department is improved.

Further, thepressing piece 17 is screwed to thepull rod 19, so that the relative distance between the pressing piece and the pressure sensor can be adjusted.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
