A floating object cleaning device for use in a dam reservoir

Abstract

A floating debris removal device for use in dam reservoir areas addresses the common problem of floating debris accumulation in reservoirs. Traditional methods are costly and risky, with personnel constantly exposed to the water at risk of falling in. Especially in non-navigable reservoir areas, large debris-grabbing equipment struggles to access the area and cannot clean critical areas, leading to long-term debris buildup and the risk of clogging inlets and impacting gates. This invention comprises a main net body and side net bodies. The main net body is composed of horizontal beams, vertical beams, a middle beam, and an iron mesh. The side net bodies are composed of a bottom beam, side beams, and an iron mesh. The side beams are connected by traction ropes. The main net body and the side net bodies are welded together to form a trapezoidal structure. This invention is used for cleaning floating debris in dam reservoir areas.

Description

Technical Field

[0001] This utility model relates to a floating debris removal device for use in dam reservoir areas. Background Technology

[0002] Reservoir areas often accumulate floating debris such as branches and garbage. Traditional cleaning relies on manual dredging or the use of debris nets. Manual dredging is time-consuming, costly, and risky, with personnel constantly exposed to the water at risk of falling in. Traditional plastic debris nets are easily damaged, have poor impact resistance, and are prone to breakage by hard objects such as branches. Furthermore, the degradation of the plastic material can cause secondary pollution. Especially in reservoir areas without navigation, large garbage grabbing equipment has difficulty accessing and cannot clean key areas (floating debris barriers, in front of gate slots), leading to long-term accumulation of floating debris. This poses a risk of clogging the intake, impacting the gates, and threatening the safety of hydraulic structures. Utility Model Content

[0003] In order to overcome the problems of existing cleaning devices that may cause personal injury, high salvage costs, low cleaning efficiency and insufficient adaptability, this utility model provides a floating debris cleaning device for use in dam reservoir areas.

[0004] The above objectives are achieved through the following technical solutions: A floating debris removal device for use in dam reservoir areas comprises a base plate, a main net body, and two side net bodies. The main net body and the two side net bodies together form a trapezoidal structure. The upper turning point of the main net body and the side net bodies is welded with a support beam, and the lower turning point is welded with a connecting pipe. The two side net bodies are connected and fixed by traction ropes to form a cleaning area.

[0005] The aforementioned floating debris removal device for use in dam reservoir areas includes a main mesh body comprising two horizontal beams, two vertical beams, a long beam, and a middle beam. The two horizontal beams and two vertical beams are welded together to form a square frame structure. An iron mesh is welded inside the square frame structure. The two ends of the middle beam are welded to the midpoints of the two horizontal beams.

[0006] The aforementioned floating debris removal device for use in dam reservoir areas includes a side mesh body comprising two side beams and two side beams, which are welded together to form a square frame structure, and an iron mesh is welded inside the square frame.

[0007] The floating debris removal device for use in dam reservoir areas includes a support beam comprising two short beams and one long beam. The short beams are welded to the junction of the main mesh and the side mesh, and the long beam is welded to the two short beams. Beneficial effects

[0008] 1. This utility model is highly practical and can address the pain points of scattered floating objects in reservoir areas, time-consuming manual retrieval, and easy damage of traditional debris-blocking nets. It eliminates the need for manual operation, reduces the risk of people falling into the water, and enhances safety during operation.

[0009] 2. This utility model utilizes a trapezoidal iron mesh. The device achieves rapid assembly and disassembly by connecting a sturdy steel pipe fixed to the bow of the ship with holes in the iron mesh, requiring no professional training and shortening deployment time. The iron mesh is coated with an anti-corrosion coating, and the junctions between the main mesh and the side mesh are welded with support beams and connecting pipes, improving the device's durability and reducing equipment replacement frequency and maintenance costs. It is suitable for reservoir areas and waterways where floating debris is scattered and large equipment cannot access, supporting cleaning operations in key areas such as the front of the sewage discharge gates and floodgates of hydropower stations.
