Device for clearing away limnoperna fortunei in pipeline and method

Abstract

The invention relates to a device for clearing away limnoperna fortunei in a pipeline and an application method. The device comprises a clearing part and multiple hook wires. The clearing part is of ahollow cylinder structure and is of a flexible structure, and at least one fixed rod is arranged on the inner wall of the clearing part in the circumferential direction at intervals. A tightening part is connected to the bottom of the clearing part and can reduce the occupied space of one end of the clearing part. A connecting rod is fixedly mounted at one end of the tightening part. One end of the connecting rod is movably connected with a rolling wheel. When the clearing part penetrates into the pipeline, the rolling wheel can reduce friction force between the pipeline and the clearing part. The hook wires are arranged at intervals in the length direction of the clearing part, the hook wires can hook byssi of the limnoperna fortunei, the limnoperna fortunei in the pipeline can be cleared away conveniently, and use is convenient.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a cleaning device and method for freshwater shell vegetables in a pipeline. Background technique [0002] Freshwater shellfish are easy to adhere to the surface of hydraulic structures and are not easy to remove.

Problems solved by technology

[0002] Freshwater shellfish are easy to adhere to the surface of hydraulic structures and are not easy to remove. The freshwater shellfish adhered to the inner wall of the pipeline will corrode the wall surface, and the secreted chemical substances will cause the cement to fall off. Reduce the flow area of ​​the pipeline, so that the pipeline is easy to form cavitation, etc.; freshwater shellfish fouling on important structures such as filters, biofilms, coolers, pumps and gates will cause equipment blockage and necrosis, bringing huge safety hazards and economic loss etc.

[0003] The harm of freshwater shellfish to water conservancy projects has become increasingly prominent, causing serious biofouling problems on the surface of hydraulic structures. The erosion situation is becoming more and more serious. In the production process, due to the long or difficult dismantling of water pipelines and other equipment, there is a lack of targeted theoretical basis and effective prevention and control methods for controlling the flooding of freshwater shell vegetables and other attached organisms.
