AI Technical Summary
In artificial ecological wetlands, fish live in four and five types of water bodies with poor water quality, which leads to difficulties in fishing and fishing. The overflow structure of traditional terraced wetlands is open, and fish can flow freely, increasing the fishing workload. For situations where the overflow port is large or the door structure is complex, directly installing an interceptor door may cause the retaining wall to collapse.
An artificial ecological wetland overflow port blocking device is designed, including an infrastructure across the overflow port, a number of support legs inserted into the riverbed, a hollowed-out frame, a U-shaped groove and a liftable water gate. The device builds an interception structure on the riverbed through the infrastructure and support legs to avoid additional force applied to the original retaining wall, and uses a diagonal bar design to intercept floating objects and operate to clean up garbage.
By setting up lifting doors at the overflow port, fish are effectively prevented from swimming downstream or natural water bodies, and the overflow level and flow rate are adjusted, which avoids damage to the original retaining wall and facilitates the operation of floating objects and garbage from the water surface.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of water pollution control, in particular to an overflow blocking device for an artificial ecological wetland. Background Art
[0002] At present, common artificial ecological wetlands are designed as highly staggered terraced structures, and overflow outlets are set at the downstream end of each area to allow natural flow, aiming to simulate the function of natural wetlands to achieve water purification. Aquatic plants, microorganisms and fish are placed in each area to improve the purification effect of water bodies by establishing an ecosystem that simulates nature.
[0003] Since the fish live in Class IV and Class V water bodies with poor water quality, fishing is usually prohibited and these fish need to be regularly harvested and properly handled. Since the overflow structure of the traditional terraced wetland area is open, fish can flow freely between areas, which brings additional workload to centralized fishing.
[0004] For overflows and door structures with smaller dimensions, the door structure can be directly installed on the regional retaining wall. However, for overflows with larger dimensions or complex door structures, installing the door directly on the original wooden retaining column structure may cause collapse due to the greater impact of the water flow.
