Technical Field
[0001] The utility model relates to the technical field of drainage well grates, in particular to a well grates with filtering function for road water supply and drainage. Background Art
[0002] The filter grates in road water supply and drainage equipment are used to cover the entrance of the drainage system under the road, allowing rainwater to pass through while blocking larger solid particles to prevent clogging of the drainage pipes. The design of this grating usually takes into account the filtering performance, load-bearing capacity, durability and coordination with the urban environment.
[0003] Manhole grates are usually made of corrosion-resistant and wear-resistant materials, such as stainless steel, cast iron or special alloys. These materials can operate stably for a long time in humid, high-temperature and chemically corrosive environments, and have certain mechanical strength and durability. However, some filter devices in the prior art are difficult to lift, and operators need to continuously lift or move the filter devices with force, which may cause fatigue when handling large amounts of liquid or during long-term operations. The filter devices cannot be lifted or cleaned in time, which will cause the filter mesh or channels to be clogged. This will hinder the flow of water, reduce the efficiency of the drainage system, and even cause problems such as water backflow or flooding. For this reason, a manhole grate with a filtering function for road water supply and drainage is proposed to solve the above problems. Utility Model Content
