The gate opening / closing operation using the conductive gate according to the present invention will be described in more detail as follows.

7 is a hydrological operation diagram of a conduction gate according to the present invention.

As shown in the drawing, the conductive gate of the present invention is driven by driving the actuator 10.

The actuator 10 may be operated manually or automatically by motor drive.

When the driving force is transmitted to the gear box 30 by the first spindle 20, the vertical first spindle 20 is rotated by the driving of the actuator 10. When the driving force is transmitted to the gear box 30 by the first spindle 20, And the second gear shaft 32 is rotated by the first gear shaft 31.

The second gear shaft 32 of the gear box 30 is connected to the horizontal second spindle 40 so that the first sheave 50 connected to the opposite side of the second spindle 40 is rotated.

The first wire rope 60 wound on the first sheave 50 and the second wire rope 80 are simultaneously wound by the rotation of the first sheave 50 so that the water gate G, The water channel is closed while rotating.

Thus, the water level is adjusted according to the angle by which the water gate (G) is rotated, and the water gate (G) is rotated as much as possible to close the water channel.

The first wire rope 60 and the second wire rope 80 wound by the first sheave 50 and the second sheave 70 are loosened when the actuator 10 is driven in reverse, The wire rope 60 and the second wire rope 80 maintain a constant tension by the weight of the worm G so as to open the worm G. [

On the other hand, there are cases in which the quantity of water flowing through the channel exceeds the range of water level control by the water gate (G).

Therefore, it is possible to control the water level only by the water gate (G) in usual. However, if the water flow to the water gate (G) irregularly or irregularly increases, the water gate (G) The water level of the overflow can be adjusted by manually operating the preliminary water gate 100 provided at the upper part.

More specifically, the amount of water introduced into the gates (G) is usually kept at a level not exceeding the level of the gates (G), but when the water is discharged or the amount of the waters increases in an unexpected place, ) Over the height of the flood occasionally occurs.

In particular, if a large amount of sewage is introduced into a river by the overflow of the sewage, the water quality control of the river can not be properly performed. Therefore, a large amount of contaminated sewage may contaminate the river.

In order to prevent flooding of the sewage, the present invention operates the preliminary water gate 100 formed at the upper end of the water gate G so that the control water level can be maintained at a higher level.

That is, when the sewage rises above the normal water level controlled by the water gate G, the ball screw 101 on one side or both sides of the guide wall 90 side of the water gate G is manually operated by a separate tool So that the preliminary water gate 100 is raised as shown in FIG.

When the preliminary water gate 100 is raised at the same angle as the water gate G, the control water level becomes higher by a certain height and the sewage discharged more than the normal water level can be safely controlled.

Controlling the level of the sewage flowing into the river makes it possible to control the discharge of the sewage appropriately according to the amount of the stream, so that the water quality management of the stream can be efficiently performed.

Particularly, the present invention can be installed at a considerably lower cost than the hydraulic gate opening / closing apparatus of the conductive gate, and does not affect the operability of the water gate (G) due to contact with water. There is an advantage of improving durability.

In addition, there is an effect that it is possible to safely control from a remote place from the water gate (G).
