Description

[0001] The present invention relates to a water level control panel and a water level control apparatus including the water level control panel,

The present invention relates to a water level control panel and a water level control device including the water level control panel. More particularly, the present invention relates to a water level control panel for improving corrosion resistance, including FRP, And to a level control device for maximizing the efficiency.

In general, the water level control device may be a device for a kind of fresh water which is used for a special purpose by adjusting the water level, and a rubber dam, which is a kind of water level control device, is used for the purpose of water intake for agricultural industry and fresh water for amusement.

Rubber dams, one of the water level control devices, can effectively obtain water reserves in mountainous areas and in poor geographical conditions.

These rubber dams are attracting much attention because they are easy to assemble and install and are controlled by controlling the height of the rubber dam by air pressure according to the desired water level.

Basically, the rubber dam is filled with air for expansion and contraction of the rubber tube (airbag), and a fixing device for fixing the rubber tube to the bottom concrete and a piping system for supplying or discharging air And an additional device.

Such a rubber dam is provided with a rubber tube and a weir so that it does not interfere with the area of the receiving end of the river when it is in an overturned state. However, there is a limitation in the level of the water level, There was a problem in resilient functioning.

In addition, since the rubber tube is directly exposed to the emulsion coming down from the upper stream, when the rubber tube is impacted by falling rock in the mountainous area or sharp emulsion such as drifted into the bed by strong water pressure, the rubber tube is torn, There is a problem that the water leakage portion is generated and the function as the bank dam can not be performed.

In order to solve such a problem, recently, an airbag such as a rubber tube and a high-strength panel are used to form a beam, which is then pneumatically controlled to control the degree of expansion or contraction of the airbag, And a pneumatic moving beam which protects the rubber tube from burning due to the emulsion from the upstream in advance by blocking the panel is used.
