Description

Technical Field

[0001] The utility model relates to the technical field of water flow monitoring equipment, in particular to a water volume monitoring device for a sewage outlet into a river. Background Art

[0002] When sewage is discharged into a river, its flow rate needs to be monitored in real time to prevent excessive or even irreversible impact on the ecological environment of the river basin.

[0003] When sewage is discharged, it is usually discharged through open channels and drainage channels, and a radar flowmeter is installed above the drainage channel to monitor the flow of sewage in the drainage channel in real time. The radar flowmeter measures the flow rate and water level of sewage in a non-contact manner, and then calculates the flow rate of sewage based on the known shape of the drainage channel. Due to the non-contact measurement, the radar flowmeter will not be polluted and corroded by sewage and affected by sediment. However, when the radar flowmeter is working, the ultrasonic wave emitted from its bottom surface must be perpendicular to the water surface, otherwise it will affect the measurement results and cause the measured flow value to be inaccurate.

[0004] The installation of radar flowmeters is usually done by pouring a concrete foundation beside the sewage channel, and then erecting a support pipe on the concrete foundation, with a cantilever on the support pipe, and the radar flowmeter is fixed on the cantilever. Since the concrete foundation is located beside the sewage channel and is also close to the river, the surrounding soil has a high moisture content and poor soil stability. The support pipe is affected by the unbalanced force of the cantilever and the natural wind. After working for a long time, it is easy to cause the concrete foundation to tilt, and then the support pipe to tilt. When the radar flowmeter is working, the ultrasonic wave emitted by its bottom surface is no longer perpendicular to the water surface, resulting in inaccurate measured flow values. If not discovered and handled in time, these inaccurate flow values ​​will affect the subsequent supervision and management of sewage discharge. Utility Model Content

The weight block 15 and the fixing block 12 are both connected to a wire 4 , and the wire 4 is electrically connected to the distribution box 6 .

[0030] like Figure 3 As shown, when the concrete foundation 1 tilts, the support tube 3 is tilted, while the pull rod 14 remains vertical.
