Description

Technical Field

[0001] The utility model relates to the field of floating object cleaning devices at dam water inlets, in particular to floating object cleaning equipment at water inlets of water conservancy and hydropower dams. Background Art

[0002] Water conservancy refers to the use of various artificial measures to control, regulate, govern, develop, manage and protect surface water and groundwater such as rivers and lakes in nature to reduce and avoid water and drought disasters. It is usually used in flood control, irrigation, power generation, water supply, shipping, aquaculture and other undertakings. Because of environmental pollution, there are often many floating objects on the river surface and river channels. If these floating objects are not handled, they will cause water pollution. Traditionally, floating objects in rivers are mostly salvaged and cleaned up by manual operation on operating boats, which is slow and inconvenient, labor-intensive, and inefficient. Therefore, a floating object cleaning device at the water inlet of a water conservancy and hydropower dam disclosed in Chinese patent publication number CN114837141A can adapt to water inlets of different sizes by adjusting the distance between two side plates, so as to meet different usage requirements and improve adaptability.

However, a plurality of water inlets are usually arranged on the dam body. If the device is arranged at a water inlet near the middle position, it will be far away from the dam body, making it difficult to push the floating objects onto the dam body. Utility Model Content
