Problems solved by technology

However, due to negligent care, the manhole cover was forgotten to return to its original position after the accumulated water was discharged, so that the wellhead sealed by the original manhole cover was directly exposed on the road surface, causing passing pedestrians or vehicles to fall into or fall into the well without paying attention;
[0007] (1) Most of the existing manhole covers with reminding function are to remind passers-by by sirens or warning lights. cause safety accident

Abstract

The invention discloses an automatic opening and closing system for a manhole cover. The system is characterized in that a manhole seat is laid at a manhole of a sewer, and a processor module, a position adjusting module, a sensing module and a power module are installed in the manhole seat; the input end of the processor module is connected with the sensing module and the power module, the outputend of the processor module is connected with the position adjusting module, the output end of the power module is also connected with the power module, and the sensing module detects the water flowof a sewer. The manhole cover is opened according to the flow speed and the water level of the water flow, and is opened if the water flows rapidly in rainy days to allow rainwater to flow into the sewer rapidly; after the flow speed of the water flowing through the sewer changes, an internal generator can provide electric energy for the opening and closing system by hydraulic power generation, the sensing module detects the change of water flow and water level in the sewer to judge whether it rains, a cylinder and the generator works, and after the manhole cover is rotated, the water furtherflows into the sewer rapidly.

Description

technical field [0001] The invention relates to the technical field of manhole covers, in particular to an automatic opening and closing system for manhole covers. Background technique [0002] As a part of urban road municipal facilities, municipal manhole covers are closely related to the work and life of citizens. According to statistics from the Guangzhou municipal maintenance and management department, there are more than 50,000 municipal manhole covers managed by the city alone in Guangzhou, and telecommunications, cables, gas and tap water It may be as many as hundreds of thousands if the manhole covers are included together. Such a large number of municipal manhole covers without a good management and high-quality municipal manhole cover quality and anti-theft measures will not only cause great safety hazards to citizens, but also bring unsafe factors to vehicles and cause major economic losses to the government . Therefore, the quality of municipal manhole covers ...
