When a service person needs to view the flow data at the connecting pipe 13, the inspection space 140 can be accessed by removing the manhole cover 144 at the opening 143 or by observing the devices within the inspection space 140 at the ground to read the real-time flow data.

In some embodiments, the leachate delivery system 10 further comprises a control device 16, the flow detection device 15 is electrically connected to the control device 16, and the control device 16 is configured to receive the flow signal sent by the flow detection device 15. In this way, the real-time flow detected by the flow detection device 15 can be transmitted to the control device 16 through the flow signal, and the control device 16 can realize remote monitoring, so that the data of the flow detection device 15 does not need to be read on site, and the working efficiency is effectively improved.

Therefore, the running condition of the leachate conveying system 10 can be monitored in real time, and an alarm is sent to a maintainer in time to prompt abnormity.

It will be understood that the preset flow rate may be set as a standard flow rate of the leachate delivery system 10, or may be set as a dangerous flow rate value determined according to the actual risk of blockage of the connecting duct 13 and the choked flow of the liquid, and is not limited herein.

In particular, the alarm means 17 may comprise a buzzer and/or an LED lamp. That is, the alarm device 17 includes a buzzer, or the alarm device 17 includes an LED lamp, or the alarm device 17 includes a buzzer and an LED lamp.
