Problems solved by technology

However, judging from the collected hull parameters of various types of ships, the ships are relatively large in size and have considerable geographical restrictions, so they are not suitable for garbage collection in small watersheds

Embodiment 1

[0053] A river in a city has a width of 10m, an average velocity of 1m / s, and an average water depth of 2m.

[0054] Use a current meter to measure the speed of the river at intervals of 1m in width and 1m in water depth, and use the collected samples to draw a three-dimensional flow velocity distribution cloud map. After the ANSYS FLUENT simulation test, the optimal depth of the power generation device of the Venturi floating garbage collector is 0.6m. By making a section at 0.6m on the flow velocity distribution cloud map, take extreme points on it and mark them.

[0055] Temporarily set up interception nets on the river, count the volume of garbage interception at intervals of one hour, and repeat the test for several days to obtain the garbage flow distribution table. Take the maximum value in the table as the standard value of garbage flow (estimated garbage flow), according to the standard value of garbage flow, and according to the garbage storage volume of the selecte...

Abstract

The invention relates to a method for collecting water surface floating garbage through a venturi water surface floating garbage collector. On the basis of the venturi water surface floating garbage collector, according to the method, a stable garbage recycling period is taken as a target, according to an initial calculation period, site mounting is carried out, according to the condition of garbage recycling each time, feedback adjusting is carried out, a final stable recycling period is obtained, and finally, continuous stable recycling of the water surface floating garbage can be achieved.Compared with the prior art, a certain number of collectors are reasonably distributed on the river, automatic collecting of the water surface garbage can be achieved, the water surface garbage collecting efficiency can be improved, manpower, material resources and energy can be saved, work cost is reduced, periodization and sustainability of garbage recycling can be achieved, and convenience is provided for cleaning work of water area garbage.

Description

technical field [0001] The invention relates to the field of river environment garbage cleaning equipment, in particular to a method for collecting floating garbage on the water surface by a Venturi type water surface floating garbage collector. Background technique [0002] With the gradual acceleration of urbanization, various urban landscape waters and small artificial lakes are emerging, as well as artificial landscape waters and water ecological restoration construction projects in various cities. However, the main pollutants in some areas of my country's urban rivers, especially landscape water bodies, are floating garbage, which has high ecological hazards and seriously affects the city appearance. At present, the cost of daily garbage cleaning and regular salvage in rivers and other waters is high. The floating objects were salvaged. This method requires more labor, poor working conditions, more time-consuming, and lower efficiency. Therefore, the research and dev...
