[0002] As the main component of the urban rainwater system, the rainwater inlet is responsible for preventing water accumulation on the road, which is very important for ensuring the normal traffic of urban roads and preventing urban waterlogging. However, some street shops dump food waste and kitchen sewage into the rainwater inlet for their own convenience. These garbage accumulate in the rainwater inlet, causing the rainwater inlet to emit a foul smell, which not only affects the appearance of the city, but also easily breeds mosquitoes and rats, posing a threat to the surrounding environment and people's health. In addition, after entering the rainwater pipe system, kitchen sewage is also very easy to block and corrode the pipe, and enter rivers and lakes from the end of the pipe, causing serious damage to the water ecological environment. These problems are obvious, but they are very difficult to manage. Specifically, as follows: From a management perspective, there are many catering industries in the jurisdiction of the urban management department, and the rainwater inlets are scattered, so it is difficult for managers to achieve significant results through supervision and law enforcement. Therefore, it is crucial to design a rainwater inlet structure that fundamentally prevents people from dumping sewage and garbage into the rainwater inlet. Summary of the invention
