Trash collecting net device

Abstract

The invention discloses a trash collecting net device and relates to the technical field of floating-type trash holding devices applied to trash holding of water conservancy and water intake engineering. The trash collecting net device comprises a trash holding net, a plurality of pontoons and a plurality of hanging drooping chains. High-strength and high-modulus polyethylene fiber ropes are arranged on the upper edge of the trash holding net. The circumference of each pontoon is provided with a groove. The circumference of each pontoon is tightly bound by a high-strength low-malleability rope along the corresponding groove. Each pontoon is connected with the corresponding high-strength and high-modulus polyethylene fiber rope through the corresponding high-strength low-malleability rope. The hanging drooping chains are bound on the lower edge of the trash holding net through ropes and located under the pontoons respectively. The length of the hanging drooping chains is as same as that of the pontoons. The trash collecting net device can be used for collecting and cleaning away floating objects in a common river, a city river and the water inflow upstream part of a hydropower station. The trash collecting effect is good, using is convenient, and the safety is high. The maneuverability is high, and the floating objects are collected and disposed fast. The trash collecting net device can be arranged under the circumstance that riverway traffic is not affected. The cleanliness and sanitation of water flow is ensured, and the requirements of environment and working conditions are met.

Description

technical field [0001] The invention relates to the technical field of a floating trash-stopping device used in water conservancy and water intake projects. Background technique [0002] At present, almost all water conservancy and water intake projects are equipped with sewage blocking devices at a certain distance from their water inlets in order to filter out the floating objects floating with the water upstream, so as to facilitate collection and clean water sources. The pollutants in urban rivers are constantly increasing. The flexible and convenient sewage collection net device can be installed at the inlet and outlet of the river to block the indiscriminate flow of debris, which is convenient for collection, cleans the water source, and protects the environment. [0003] Since the design of domestic trash-stopping and sewage-collecting devices is still in the exploratory stage, and there are many uncertain factors and particularities in the design, domestic trash-stop...

AI Technical Summary

Problems solved by technology

The existing rigid waste blockage works better, but most of them are made of metal structures, which are welded by steel cylinders, strips, and plates. The investment is large and the structure is heavy, which affects traffic; Under the action of actual water flow alternating force, it is easy to cause fatigue fracture and difficult maintenance

Most of the flexible trash-blocks in the existing structure are node-hinged and interact with each other, and under the impact of water flow and sundries, the underwater trash-block will form a larger arc, reducing the The trash blocking depth is limited, the trash blocking effect is not good, and it is difficult to clean up the drift
