Telescopic overwater trash holding device

Abstract

The invention provides a telescopic overwater trash holding device which comprises a plurality of trash holding bodies and a trash blocking net. The plurality of trash holding bodies are sequentiallyarranged in the width direction of a river way. Each trash blocking body comprises a floating box and a blocking stand column arranged at the top of the floating box. Every two adjacent blocking standcolumns are connected through a telescopic cross brace, the top ends of every two adjacent blocking stand columns are connected through a telescopic hanging net connecting rod, and the two trash blocking bodies closest to the two sides of the river way are movably connected with the corresponding river banks, so that all the trash blocking bodies ascend and descend along with the water level; andthe trash blocking net is connected with the hanging net connecting rods, so that the trash blocking net covers the area between the two adjacent blocking stand columns. The length of the telescopicoverwater trash holding device can be adjusted according to the width of the river way, and the telescopic overwater trash holding device is simple in structure, fast to disassemble and assemble, lowin manufacturing cost and convenient to transport, store and maintain.

Description

technical field [0001] The invention relates to the field of water conservancy engineering, in particular to a telescopic water pollution-stopping device. Background technique [0002] At present, the arresting nets used in water conservancy projects are mainly used to block floating objects in waters to prevent floating objects from affecting the waterway, so as to facilitate the centralized removal of floating objects and protect the river landscape. For example, a large number of water hyacinths grow in the branch rivers of the Huangpu River every year, and often enter the inland waterway with the water flow. Therefore, water hyacinth should be intercepted when it enters the estuary of the inland channel. There are many estuaries that need to intercept floating objects, and there are more than a thousand in Minhang District, Songjiang District, Qingpu District, Pudong New Area, etc. of Shanghai alone. It can be seen that there will be tens of thousands of river courses ...

AI Technical Summary

Problems solved by technology

If the net height is designed according to the normal water level, the high water level will not be blocked, and the floating objects will pass over the net

Especially in the season when there is no need to block floating objects, the trash net is not only inconvenient to disassemble and difficult to maintain, but also has no effect when placed in the river course, affecting the landscape

This situation is especially prominent in coastal cities, where the water level of the tide rises and falls, and the required blocking height is also constantly changing, so the height of the trash net cannot be adjusted adaptively.

In addition, since the trash-blocking net is fixed, it is difficult to remove the trash-blocking net in the season when the trash-blocking net is not needed
