Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of municipal drainage well, concretely relates to a warning device of drainage well. BACKGROUND

[0002] The municipal drainage system is an important part of urban construction, which is composed of rainwater pipe network, sewage pipe network, pumping station and sewage treatment plant. These facilities work together through underground pipe network to collect and transport wastewater, effectively treat wastewater and prevent urban waterlogging. The design concept of drainage system is based on rain and sewage separation, which ensures that rainwater is directly discharged into the river after preliminary runoff treatment, and sewage is transported to the sewage treatment plant through the pressure pipeline. In the sewage treatment plant, sewage will undergo a series of purification treatment processes, including four-stage purification treatment of sedimentation tank, biological reaction tank and disinfection tank, so that the effluent quality meets the national discharge standard, effectively avoiding water pollution and ensuring public health safety and environmental quality. Therefore, the quality of drainage system directly affects the operation efficiency of city and the quality of life of citizens.

[0003] As the terminal node of drainage system, drainage well is usually made of reinforced concrete or prefabricated assembly structure, which is connected with the main pipe network through branch pipe to guide the accumulated water on the road surface into the drainage system for collection and transportation. In order to prevent pedestrians or vehicles from falling into the drainage well by accident, the wellhead of drainage well is equipped with a well lid. However, during the rainy season, when the rainfall is large, the existence of well lid will reduce the drainage efficiency, resulting in slow speed of accumulated water on the ground into the drainage system, and further affecting people's travel. In order to improve the drainage efficiency, it is usually necessary to open the well lid before it rains to increase the drainage capacity, so as to quickly drain the accumulated water on the ground. After opening the well lid, in order to prevent pedestrians or vehicles from falling into the drainage well by accident, a warning device must be set up at the wellhead of drainage well to remind pedestrians or vehicles to pay attention to safety and avoid falling into the well. The warning device is usually composed of a bracket and a warning sign, but the bracket cannot be folded, so a lot of space is occupied during transportation, and multiple vehicles are needed for transportation. In addition, the wellhead structure of drainage well is usually circular or square, and the existing warning device has single assembly, which is difficult to adapt to the assembly demand of wellhead with various shapes.
