Automatic winding and unwinding trash-blocking screen

Abstract

The invention provides an automatic winding and unwinding trash-blocking screen. The automatic winding and unwinding trash-blocking screen comprises a reelpipe, a tubular motor, a screen body and a controller, the two ends of the reelpipe are provided with buoys, and the controller controls the tubular motor to be started and stopped; and when the automatic winding and unwinding trash-blocking screen is in the non-use state, the screen body is wound on the reelpipe, when the controller receives information sent from a water quality sensor and a water level sensor, information is sent to make the tubular motor work, the tubular motor rotates and drives the reelpipe to rotate, the reelpipe rotates to enable the screen body to expand under the water body liquid surface, and the controller controls the screen body to be wound or be unwound in real time according to the information of the water quality sensor and the water level sensor. According to the automatic winding and unwinding trash-blocking screen, winding and unwinding of the screen body can be automatically controlled according to change of the water quality and the water level in a water body, the problem that a trash-blocking screen is single in structure and cannot make the corresponding response according to change of the current water quality and the water level in the prior art is solved, manpower is greatly saved,and the operation difficulty is reduced.

Description

technical field [0001] The invention relates to the technical field of water body trash blocking, in particular to an automatically retractable trash screen capable of realizing automatic retraction and retraction of the trash screen. Background technique [0002] With the development of the coastal economy, there are more and more maintenance dredging projects for major harbor basins, waterways, and anchorages along the coast, as well as excavation projects for harbor basins and waterways in newly built ports. During the construction process of traditional dredging projects, it is inevitable that the mud will spread due to the agitation of the underwater sediment, which will cause certain pollution to the surrounding waters. If the dredging is not carried out for a long time, it will even have a serious impact on the surrounding marine environment. On the other hand, in river and lake water environment treatment projects, the treatment of heavily polluted or slightly pollut...

Problems solved by technology

[0004] In the long-term treatment process, people have found that whether it is a permeable or impermeable trash screen, there is a problem that the trash screen needs to be retracted and put down manually.

With the increasing difficulty of treatment, and the different requirements for pollution control screens and treatment methods under different water conditions and different degrees of pollution diffusion, the pollution control screens in the prior art have been difficult to meet the above requirements due to their single structure and function.
