The communication module 12 uniformly outputs the information data to the server, so that the working personnel can monitor the operation condition of the drainage pipe network on line. The drainage pipe network monitoring equipment provided by the invention can replace manual work to monitor the drainage pipe network so as to improve the intelligent management level of the drainage pipe network.
In some embodiments of the present invention, a drainpipe network monitoring device includes a base 16, a connector, and a fixture. The first end of the connecting piece is connected with the base, and the second end is connected with the drain pipe so as to connect the base into the drain pipe.

Further, the fixing means includes a pillar 18 and a jig. The post 18 is connected to the base 16. A clamp is provided on the post 18 for securing the detection device 22. For example, the fixture may include a plurality of loops 20, and the sensing devices 22 may be nested within the loops 20 in a one-to-one correspondence. In actual use, after the detection device 22 is mounted on the fixture, the base 16 is fixed on the well wall by rivets 23 or screws, etc. to prevent the detection device 22 from being washed away by water flow. The detection device 22 can be located at a high position by providing the support column 18, preventing the detection device 22 from being buried by sludge.
In some embodiments provided herein, the detection device comprises a flow meter. The drainpipe network monitoring device also comprises a support rod 26, a sliding rod 28 and a floating body 30.
Wherein, the support rod 26 is a hollow structure. And, the support rods 26 are connected to the well wall and/or the well lid. The slide rod 28 has a first end slidably extending into the support rod 26 and a second end adapted to extend into the drain pipe. A floating body 30 is connected to the second end of the sliding rod 28, and the floating body 30 is used to float on the water surface. The flowmeter 42 is provided at the bottom of the floating body 30.
So set up, float body 30 and float on the surface of water all the time in the use, when the water level in the drain pipe changes, float body 30 and go up and down along with the surface of water goes up and down, can make flowmeter 42 soak below the surface of water all the time to make flowmeter 42 when detecting the water flow in the drain pipe, can not receive the influence of the water level height in the drain pipe.

For example, the guide member 36 may comprise a linear bearing or a graphite sliding sleeve. The friction between the sliding rod 28 and the supporting rod 26 can be reduced by the guiding component 36, so that the floating body 30 can be more flexibly lifted and lowered along with the water level. Further, the first end of the sliding rod 28 is provided with a stopper 32, the stopper 32 is located above the guide member 36, and the cross section of the stopper 32 is larger than the inner hole of the guide member 36 to prevent the sliding rod 28 from being released from the support rod 26.
Optionally, a seal 38 is provided at the mouth of the second end of the support rod 26. The seal 38 is in sliding engagement with the slide bar 28 and serves to prevent debris from entering the support bar 26. For example, the seal 38 may be a teflon seal cartridge.

The sliding rod 28 can only slide along the vertical direction through the matching of the sliding piece and the long groove, and the sliding rod 28 is prevented from rotating in the sliding process, so that the problem that the flowmeter cannot accurately measure the water flow due to the fact that the floating body 30 is inclined due to the fact that water flow impacts the floating body 30 is solved. Of course, the long groove provided on the support rod 26 and the slider provided on the slide rod 28 can also achieve the effect of restricting the rotation of the slider.
Further, as shown in fig. 4, it is assumed that the water flow direction in the figure is from left to right. The flowmeter is arranged in the transverse pipe on the upstream side of the vertical shaft.

The conductivity of the node where the equipment is located can be obtained through the conductivity electrode for diagnosing the water quality of the pipeline, and the conductivity is sensitive to the change of the water quality in the drainage pipeline, so that the water quality condition can be obtained through the conductivity of the water in the drainage pipeline.
The pipeline fault diagnosis can be jointly used by a plurality of drainage pipe network monitoring devices, and by combining the pipeline flow diagnosis and comparing the pipeline flow numerical values detected by the drainage pipe network monitoring devices, the conditions of pipeline damage, blockage, inflow infiltration, stealing and leaking drainage and the like of the drainage pipe network system can be judged, and the sections of the pipeline damage, blockage, inflow infiltration and stealing and leaking drainage can be determined. And the early warning can be timely carried out on the background when the pipeline is determined to be damaged, blocked, infiltrated in inflow or leaked and discharged in a stealing mode.
