The present invention installs drainage doors and drainage pumps in river or river banks so that sewage or internal water flows into rivers or rivers, and does not flow into rivers or streams. In the well-known pump operation, the river water level sensor and the water level sensor of the drainage construction are respectively installed on both sides of the drainage door, and the motor and the drain pump are automatically operated by the signal of the water level sensor so that the river water level becomes the water level of the drainage port. Automatic drainage system that automatically drains the drain door by the simultaneous drain pump that automatically closes the drain door and opens the drain door to stop the drain pump when the river water level is lower than the drain level. It is about.

Conventionally, the doors can be opened and closed by the motor to the drain door installed in the river or river chimney, and the drainage pump is installed to prevent the simultaneous river or river water draining out of the drain door while the drain door is artificially closed. Since the water level was monitored every day, the opening and closing of the drainage door and the maneuvering of the drainage pump were artificially operated. There was a problem of unjust flooding, such as flooded back to the house and flooded.

The present invention is designed to lift and open the door by a motor to the drain door installed in the river or river chimney to correct the deficiency of flood prevention due to such artificial manipulation, and when the door is closed by installing the drain pump, the water inside the drain door is In the known water drainage, the water level sensor and the drainage construction level sensor are installed in and out of the drain door, respectively, to be connected to a known electronic controller, and the output wire of the electronic controller is connected to the motor and the drain pump so as to operate the river water. When the water level is lower than the water outlet side, the motor operates to open the drain door, and when the water level is higher than the water drain level, the simultaneous drainage pump is operated by the power supply of the electronic controller to close the drain door by the operation of the motor. Drain the water from the drain while preventing flooding inside the drain door It is designed to automatically manage and control the drainage door while preventing the flooding of the drainage by forced drainage, which will be described in detail with reference to the accompanying drawings.

The door (2) is installed in the drain door (1) installed in the river or river chimney, and the motor (5) is installed through a power source such as a screw rod (3) of the door (2), a bevel gear (4) and a worm gear (4 '). In order to open and close up and down by means of the (6) and to install a drain pump (6) in the upper portion of the drain door through the suction pipe (6 ') and the discharge pipe (6 "), the known The river water level sensor 7 and the drainage level sensor 8 are installed in the inside of the electronic controller 9 so that the output wires of the electronic controller 9 are connected to the motor 5 and the drain pump 6. When the water level (W ₁ ) is detected to be higher than the drainage level (W ₂ ) by connecting to the motor, the motor (5) is automatically operated to close the door (2) and the simultaneous drainage pump (6) is automatically operated. 1) It is to drain the water on the drain 1 'side.

In the drawings, reference numerals S ₁ and S ₂ denote sensing elements or weights.

The present invention, as described above, installs and uses the detector 7 of the river water level W ₁ and the detector 8 of the water level W ₂ on the drain port 1 'at a set height, respectively. If W ₁ ) is lower than the drain outlet side water level W ₂ , there is no detection signal from both level sensors 7 and 8, and power is supplied to the motor 5 by the function of the electronic controller 9 at this time. After the door (2) of (1) is kept open and the door (2) is opened, the power supply of the motor is automatically cut off and the drain door (1) with the door (2) opened to the drain (1 '). Flowing domestic water or sewage naturally drains into the river, and as shown in FIG. 4, when a heavy rain falls suddenly or a heavy rain occurs due to the rainy season, when the river water level (W ₁ ) is higher than the drain side water level (W ₂ ), the river water level detector ( The detection signal of 7) is transmitted to the electronic controller 9 so that power is supplied to the motor 5 by the function of the electronic controller 9. The door (2) of the drain door (1) is operated to close down, and after the door (2) is closed, the water on the drain opening (1 ') side is not drained to the drain door (1). (W ₂ ) rises and the water level detection signal of the drain level sensor 8 is transmitted to the electronic controller 9 so that the drain pump 6 supplied with the power from the electronic controller 9 operates to discharge the sewage or domestic water. (1) It is configured to automatically operate the simultaneous drainage pump that closes the door of the drain door by the river water level detection signal by installing a river water level sensor and a drain level sensor on the inside and outside of the drain door. In the past, it is artificially corrected by closing and closing operation of drainage doors or drainage pumps, and when it is unknown at night, the river water blows up due to heavy rains and the water level rises automatically. By closing the drain door, the river water is prevented from flooding, so it has the effect of customarily controlling the drainage door more safely and conveniently.

Claims (1)

In the well-known thing in which the door 2 of the drain door 1 installed in the river or river chimney can be lifted and opened by the motor 5, and the drain pump 1 is installed in the drain door 1, the drain door 1 The water level sensor 7 and the drain port 1 'side water level sensor 8 are installed at the inside and the outside of the electronic controller 9, and the output wires of the electronic controller 9 are connected to the motor 5 and the drain pump. Automatic drainage device connected to motor of (6).
