[0001] Intelligent smart control flat screen [

The present invention relates to an intelligent smart control flat screen, and more particularly to an intelligent smart control flat screen capable of automatically removing contaminants when a motor is overloaded or stopped and real-time monitoring and control of operating conditions at a remote location .

Generally, in a place where water is managed such as a sewage treatment plant or a water intake station, a screen is installed on one side of the waterway to prevent various kinds of floating substances floating in the water from being carried through the waterway, And various kinds of obstacles hanging on the screen are not easy to be removed by a human force, so that a damper is installed on one side of the screen to remove various kinds of obstacles hung on the screen.

The rotary damper is provided with a frame for installation on the wall surface of the water channel, and on both sides of the inner side of the frame, a guide rail And a main screen having a plurality of diaphragms is installed between the guide rails. The main screen is installed at an angle to the bottom surface of the water channel at an angle.

In addition, there is provided a potential screen for filtering the contaminants passing between the main screen and the bottom surface at the lower front end of the main screen installed obliquely, and a rake for removing the obstacles between the screen and the potential screen is provided at both left and right ends of the screen Respectively.

Further, a drive motor for driving the endless chain by guiding the guide rail so that the rake continuously rotates on the screen is further provided, and the rake is moved to the upper side of the screen to more thoroughly remove various contaminants contained in the bucket The apron is placed on the top of the screen.

The drive motor constituting the vibration damper rotates the endless chain along the guide rails and the rake formed at regular intervals in the rotating endless chain passes through the diaphragms of the screen, Moving from the bottom to the top is repeated.

By the operation of this damper, various obstacles caught on the screen are thrown by the rake which passes between the diaphragms of the screen and moved from the bottom to the top of the screen, and is put into the bucket.

However, there is a lot of scrapes left behind between the rake in the bucket and the diaphragm in the screen through which the rake puts up the various obstacles hanging on the screen. In addition to the scum of these various impurities, There are many cases where the back is caught between the rake and the diaphragm of the screen.

If the rake is repeatedly driven in this state, not only the efficiency of removal of the contaminants drops significantly but also the rake passing through the screen is not smoothly driven, causing damage to the rake and overloading of the drive motor, There is a serious problem of remarkably dropping.

On the other hand, since the disposal facilities such as drainage pumping stations, relay pumping stations, and environmental infrastructure facilities installed in rivers and streams are mainly located outside the city, it is difficult to access the facilities and there are many constraints In case of bad weather, it is impossible to check whether the damper is operated by the existing control method.

In the conventional control system for the vibration damper, an operation control panel is provided at the site where the vibration damper is installed, and it is possible to select whether the vibration damper is operated or not by the manual operation of the operation control panel, PLC is installed to drive the rake. The PLC is connected to the drainage pump management system of the relevant facility. In the drainage pump monitoring system provided with the drainage pump management system, a system .

Such a conventional system is not only capable of remote control in addition to monitoring of a simple operation state, but also can not confirm whether or not the operation of the damper is normally operated and the processing of the obstacle is smoothly performed. There is a problem that can not be solved.

In addition, if a problem occurs when the manager is absent from the field, there is a problem that the motor is overloaded due to overload, and the operation is stopped and the drainage is not performed, thereby causing flooding.
