Description

Technical Field

[0001] The utility model belongs to the technical field of flow monitoring, in particular to a flow monitoring device for an underground rainwater and sewage pipe network. Background Art

[0002] The water flow in urban drainage pipes, fire protection pipes, gas supply pipes and other pipe networks is generally monitored by flow monitoring devices, which are instruments used to indicate the measured flow and the total amount of fluid in a selected time interval.

[0003] After searching, it was found that the Chinese patent publication number is: CN216643831U, which discloses a pipeline flow monitoring device, which includes an anti-blocking installation component and a monitoring and protection component. The anti-blocking installation component includes a flow tube, an inlet pipe, an outlet pipe, a filter cartridge and a sealing valve plate. The monitoring and protection component includes a fixing frame, a turbine blade, a flow detector, a clamping mount, a protection box and a central control processor. The central control processor is quickly installed in the protection box through the clamping part, which can prevent the central control processor from being damaged due to collision or water immersion. The large particles of impurities in it are filtered out by the filter cartridge to prevent the turbine blades and the flow detector from being deposited with too many impurities on the surface and need to be regularly disassembled for cleaning. The water flow drives the turbine blades to rotate, and the flow detector sends a rotation signal of the turbine blades to transmit it to the central control processor for calculation and processing, and displays the monitored flow data to complete the monitoring of the flow.

[0004] During use, an existing pipe network flow monitoring device filters large particles of impurities in rainwater and sewage through a filter cartridge. When too many impurities accumulate inside the filter cartridge, the water inlet pipe and the flow pipe need to be disassembled to process the impurities in the filter cartridge and replace the filter cartridge. This is inconvenient to use and has low practicality. For this reason, we propose an underground rainwater and sewage pipe network flow monitoring device. Utility Model Content
