Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a surface water intake and dust removal device provided near a river mouth (low water revetment in a tidal water area of the river mouth). In other words, near the mouth of the river, the water level fluctuates due to the tide level, and it becomes a flooded area at the time of high tide. . This surface water is fresh water, and in these basins, it is agricultural water, river purification water, and snow water sprinkling water. Therefore, a surface water intake and dust removal device that removes the surface water and dust at the same time is one of the present invention. In addition, the apparatus of the present invention can be applied to a flooded area in a gradual flat area of a general river. This is because drainage of domestic water due to delays in urban sewerage, and in agriculture, effluents into rivers due to the development of chemical fertilizers lead to eutrophication of river water, and abnormal growth of aquatic plants and algae. In addition, due to the development of petrochemicals, various kinds of dust such as vinyl-based trash, and can-uses, etc., flow into rivers, and it is necessary to remove the dust and take up surface water.

[Conventional technology]

The surface water intake system uses a float fuence for dust removal as a method of keeping driftwood and garbage away from the water intake port during water intake.However, since the garbage also sinks and floats and passes through the fuence, the surface water intake system requires A method of installing a screen (bar screen) on the entire outer periphery has also been performed. These all mean that dust is removed manually.

[Problems to be solved by the invention]

When a floating intake device is installed in a river, the installation of a float fuence for dust removal in the river is an obstacle during a flood, and its installation is not preferable. Even if dust removal means setting up a bar screen along the revetment, this requires manual scraping and is not preferable. Further, depending on the use of water, it is desired to remove fine dust. However, conventional techniques have not been able to provide practical measures.

In the dams, reservoirs, and control areas, the topography of the lake bottom gives priority to water intake at low water levels, and there are many places away from embankments, seawalls, etc., and it is not possible to install management bridges. I was In the case of rivers, the installation location is restricted by seawalls and low-water seawalls, and the water intake of the floating intake system is on one side of the river surface, a per-screen is installed, and a surface water intake system is installed at the intake well. Was. Garbage that has passed through the bar screen is removed by attaching it to the screen attached to the floating water intake device.
Not preferred.

Today, dust removal by bar screens and the like is not preferable in terms of labor saving, and automation with low power is required.Bar screens are roughened, and depending on the use of water, fine dust can be removed at the speed of running water and the water head can be reduced. There is a demand for a device that separates and flows down by power without mechanical wear and gives priority to water intake. However, it is necessary to avoid applying a large load to the float.

As described above, the conventional surface water intake apparatus requires a great deal of cost and labor and is not preferable. Therefore, the use of the floating water intake apparatus has been considered. However, a practical use apparatus has not been obtained yet.

The present invention has been made in view of this problem, and has as its object to economically obtain a highly durable surface water intake and dust removal apparatus having a simple structure and easy handling.
