Figure 2 is a perspective view showing a state fixing means installed in the opening and closing device of the automatic door of the present invention,

3 to 5 is a side view showing an operating state of the automatic door opening and closing device according to the present invention.

The present invention relates to an automatic door opening and closing device, and more particularly to an automatic door opening and closing device that can vary the blocking force of the outlet.

In general, the automatic door lock prevents the outside water, that is, the water on the downstream side from entering the inside of the dam or the outside of the water by the pressure difference according to the water level difference between the left and the right, based on the return or the water, and the inside water to the outside. It discharges and has a function of adjusting the flow rate. In particular, it is installed on the coastal embankment, and used to prevent backflow of tides, exclusion of domestic water, etc., and it can be used to discharge or control floods by installing in dams or water discharge pipes.

Korean Unexamined Patent Publication No. 1999-0062388 discloses a water gate that is automatically opened and closed by water pressure. This automatic sluice is formed in the sluice of the support member installed in the river, reservoir and agricultural waterway, the support member is installed in the upper end of the body with the axial support ball therein, and is formed opposite to the upper sides of the support member The hinge shaft is rotatably assembled, and is formed of a hollow having a predetermined size having an inlet portion at the lower side thereof, and is composed of a hydrophilic body which is inclinedly installed between the body with a weight storing portion in which weight is stored.

A non-powered automatic floodgate is disclosed in registered utility model No. 20-0329807, and a floodgate is disclosed in Japanese Unexamined Patent Publication No. 08-302654.

The said first gate has a check valve in the door body which opens and closes a waterway and is released by receiving the water pressure on the upstream side and closed by receiving the water pressure on the downstream side.

In addition, Korean automatic utility model No. 20-0262733 discloses the automatic door lock box.

That is, the driving motor 34 is operated to increase the closing force of the water gate to the discharge port 12 of the water gate to prevent the water located at the outside, that is, the water discharge side from entering the water reservoir side. In this way, the hinge shaft 13 is a discharge port that is the side of the dam 11 along the rack 36 engaged with the pinion 37 of the hinge shaft 13 installed on the guide rail 31 and the lower support 22. 12) to the side. In this way, the hinge shaft 13 is located on the inner side than the center of gravity (W) of the hydrology so that the rotation moment acts in the direction in which the hydrology is closed. Therefore, it is possible to increase the blocking force of the outlet 12, it is possible to prevent the water from the outside to flow into the inside (see Fig. 3).

In addition, in order to discharge water located inside the dam 11 to the outside, the driving motor 33 is driven to install the hinge shaft 13 on the guide rail 31 and the lower support part 22 and the pinion of the hinge shaft. Along the rack 36 engaged with the (37) is transferred in a direction away from the dam (11). In this way, the hinge shaft 13 is located outside the center of gravity W of the sluice, so that the rotation moment acts in the direction in which the sluice opens. Therefore, the water gate is opened and further, the water pressure of the inner water can be operated to discharge a large amount of water to the outside to lower the water level of the water located in the inside in a short time, thereby reducing the flood damage.

When the outlet 12 is blocked by using the water gate 14 to secure water, the hinge shaft 13 is installed on the guide rail 31 and the lower support 22 by driving a driving motor. Along with the rack 36 engaged with the pinion 37 of 13) is moved to the discharge port 12 side of the dam (11) as possible. In this way, as shown in FIG. 5, the water gate is completely closed, and the locking member 42 installed at the end thereof is in a position corresponding to the stopper 43. In this state, the actuator 45 is operated to rotate the stopper 43 to engage with the locking member 42. In this way, the rotation of the upper and lower support portions 21 and 22 with respect to the hinge shaft 13 is fixed so that the rotation of the water gate 14 is fixed, thereby discharging the outlet 12.
It can be completely blocked, and furthermore, fresh water is possible inside the dam.

When the inner water level and the outer water level of the dam 11 are kept parallel, the water gate is always kept open in the same manner as described above to secure a moving passage of aquatic organisms blocked by automatic gates or water gates.

As described above, the automatic door opening and closing device according to the present invention can open and close the discharge port by using a rotational moment due to the weight of the relatively heavy gate can implement a variety of closing and opening positions of the door. In particular, it is possible to open and close the heavy water gate with a small force can simplify the structure of the hydrological control device, it is possible to increase the reliability of opening and closing the water gate.

 Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent embodiments are possible.

Therefore, the true scope of protection of the present invention should be defined only by the appended claims.
