However, up to now, online monitoring of pipeline flow is still a shortcoming of the industry. It has also become a key link hindering the further development of the industry. The root cause is mainly because the water inflow of the drainage network is affected by multiple factors such as flood conditions, rainfall conditions, regional humanities, pipeline quality, operation technology, and scheduling conditions. In the same section of the pipeline, the pipe is often full of water and sometimes there is almost no water flow. The density of the incoming water medium is difficult to predict and is complex and harsh. The monitoring environment is difficult to track and is extremely changeable. Such an environment and working conditions make it difficult for most monitoring technologies to be used, and accurate, stable, and long-term monitoring effects are difficult to achieve.

[0016] Through the above technical solution, a radar probe is set up. When the water level in the pipeline is low, the radar function is used to implement water-out monitoring. The radar probe emits high-frequency electromagnetic waves and receives signals reflected from the water surface in the pipeline. According to the time difference between the signal emitted by the radar and the received echo, the water level inside the pipeline can be calculated, thereby indirectly calculating the flow rate.

[0030] Specifically, the monitoring pipeline 1 includes an outer pipe 101, a bracket 102, an inner pipe 103 and a connecting flange 104. The bracket 102 is fixedly connected to the inner wall of the outer pipe 101, the inner pipe 103 is fixedly connected to the center of the bracket 102, and the connecting flanges 104 are fixedly connected to both ends of the outer pipe 101. The advantage is that the monitoring pipeline 1 is provided with a double-layer structure of the outer pipe 101 and the inner pipe 103, and the structural strength is high.

[0031] Specifically, the support 102 is a grid-like structure. The advantage is that the outer tube 101 and the inner tube 103 have a double-layer structure, and the support 102 is arranged between them as a reinforcement structure, which improves the structural strength of the monitoring pipeline 1 and increases the service life. At the same time, the interlayer arrangement reduces drainage noise, which is more practical.

[0032] Specifically, the ultrasonic probe 204 is provided with eight identical ones. The advantage is that, after the ultrasonic probe 204 is provided, when the water level in the pipeline exceeds the monitoring point position, the radar function is suspended, and the ultrasonic probe 204 is started to measure the velocity of the fluid in the pipeline by emitting ultrasonic pulses and receiving their echoes. When the ultrasonic wave propagates in the fluid, its propagation time will change due to the fluid velocity, and the flow rate is measured accordingly to implement water-carrying monitoring. The combined application of the two functions can not only reduce the interference of pipeline siltation on the monitoring effect and improve the monitoring effect, but also extend the normal working cycle of the monitoring point and reduce the maintenance frequency.

[0033] Embodiment 2: Figure 2-5 As shown, as an improvement to the previous embodiment.

[0034] Specifically, eight ultrasonic probes 204 are evenly distributed radially on the inner wall of the inner tube 103. The advantage is that the eight ultrasonic probes 204 are evenly arranged, and the monitoring effect is good.

[0035] Specifically, the radar probe 203 is fixedly connected to the top of the inner wall of the inner pipe 103. The advantage is that the radar probe 203 is set.

The radar probe 203 transmits high-frequency electromagnetic waves and receives the signal reflected by the water surface in the pipeline. According to the time difference between the signal emitted by the radar and the received echo, the water level inside the pipeline can be calculated, thereby indirectly calculating the flow rate. When the water level in the pipeline exceeds the monitoring point, the radar function is suspended and the ultrasonic probe 204 is started to measure the speed of the fluid in the pipeline by emitting ultrasonic pulses and receiving their echoes. When ultrasonic waves propagate in the fluid, their propagation time will change due to the fluid speed. The flow rate is measured based on this and water-carrying monitoring is implemented. The combined application of the two functions can not only reduce the interference of pipeline siltation on the monitoring effect and improve the monitoring effect, but also extend the normal working cycle of the monitoring point and reduce the frequency of maintenance.
