Description

Technical Field

[0001] This utility model relates to the field of pipeline anti-clogging technology, specifically to an anti-clogging structure and a bend. Background Technology

[0002] Existing water intake devices are prone to sucking in foreign objects from the water tank, leading to continuous water intake interruptions and potentially jamming the valve, preventing it from closing. The water intake uses a gooseneck bend to reduce water flow velocity, making it harder for foreign objects to overcome their own weight and reducing the likelihood of them being sucked into the pipe. A removable bottom shell is designed at the bottom of the gooseneck bend to facilitate the deposition and cleaning of foreign objects. Flanges are added to both ends of the one-way valve for connection, and a filter screen is added in the water inlet direction to further prevent foreign objects from entering the one-way valve with the water flow and causing blockages. The removable flange connection facilitates disassembly and cleaning of foreign objects.

[0003] The bottom of the gooseneck bend is designed with a removable bottom shell, which facilitates the deposition and cleaning of foreign objects. However, it requires periodic entry into the water tank to disassemble and clean the bottom shell, resulting in a short maintenance cycle and cumbersome maintenance work. This not only involves a large workload but also poses certain dangers. Utility Model Content
