Description

Technical Field

[0001] The utility model relates to the field of drainage engineering of utility tunnels, in particular to a drain emptying device for sumps in utility tunnels. Background Art

[0002] A utility tunnel is an intensive and multi-functional underground public facility. The construction of a utility tunnel can effectively integrate urban underground pipelines, improve the utilization efficiency and management level of urban infrastructure, and is an important symbol of the modernization of urban infrastructure. The drain emptying device for sumps in urban utility tunnels can timely drain the accumulated water in the underground space, prevent pipeline damage and equipment failures caused by the accumulated water, thereby improving the urban disaster prevention and mitigation ability.

[0003] A water level sensor is usually installed in the sump, such as an ultrasonic water level sensor. The sensor can monitor the water level change in the sump in real time. When the water level sensor detects that the water level reaches the preset starting water level, it will send a signal to the control system. The control system starts the drainage pump according to the signal instruction to start draining. The drainage pump is the core component of the drain emptying device for sumps, and usually a centrifugal pump or a submersible pump is used. The drainage pump pumps the water in the sump through the drain pipe to a designated discharge point. As the water level drops, the water level sensor will continuously monitor the water level change. When the water level drops to the preset stop water level, the sensor will send a signal to the control system, and the control system will immediately shut down the drainage pump to stop draining. In an emergency, such as when the sump needs to be repaired or inspected, the drainage pump can be manually started through the control system to quickly empty the sump.

[0004] However, sundries, sediments in the existing sump or sediments in the pipeline will cause the drain pipe to be blocked. In addition, when the drainage pump stays in the sump for a long time, it will be damaged when the water volume in the sump is too large due to precipitation or other reasons. Therefore, a drain emptying device for sumps in utility tunnels is proposed to solve the above problems. Summary of the Utility Model
