[0001] The invention relates to the technical field of manhole grates, in particular to a rainwater hole sewage interception device and a rainwater manhole grate. Background Art

[0002] The rainwater well is used to collect and recycle rainwater, and a well grate is installed on the top of the rainwater well; the existing rainwater well grate can intercept larger debris, such as leaves, branches, garbage, etc., to prevent these debris from entering the rainwater pipe and causing blockage, but it cannot intercept smaller debris and cannot block odors and mosquitoes in the rainwater well.

[0003] The patent application number 201822058263.4 discloses an easy-to-clean automatically closed rainwater outlet, including a well grate and a porous water-absorbing material connected by an automatic reset spring hinge. The porous water-absorbing material uses the change in gravity after absorbing water to realize opening and closing through the automatic reset spring hinge. The incoming rainwater enters the sewage interception hanging basket for filtration, and the closed state is automatically changed according to different needs. It can intercept smaller debris and block odors and mosquitoes in the rainwater well; however, its disadvantages are: 1. The porous water-absorbing material opens the rainwater outlet after absorbing water, but it is difficult for the porous water-absorbing material to drain, resulting in the rainwater outlet remaining open for a long time, unable to intercept debris, and unable to isolate odors and mosquitoes. The porous water-absorbing material containing water will also produce odors itself; 2. The rainwater outlet is exposed to sunlight and rain for a long time, and the porous water-absorbing material is easily damaged and fails; 3. The rainwater well grate is blocked as a whole, and the effect is poor. Summary of the invention
