The rack bar 42 has a groove formed so that the teeth of the gear mesh with each other. The rack bar 42 moves up and down by engaging the tooth of the gear with the groove.

The first gear 611 formed on the shaft 610 of the motor 61 is a worm, and the worm wheel is applied to the second gear 612 mounted on the main shaft 62.

Accordingly, the rotational direction is switched in a direction orthogonal to the rotational direction of the motor shaft 610 by the rotation of the first and second gears 611 and 612 to transmit power.

The third gear 83 mounted on the main shaft 62 is a spur gear, and the pulley 46 of the rack unit 4 is also a spur gear, and connects the third gear 83 and the pulley 46 to each other. The means 63 is applied to the chain.

The overload protection device 7 is to cut off the power of the driving unit 6 when an overload is applied to the floodgate and the operation is not performed properly.

The first and second gears 711 and 722 are inclined surfaces 714 and 724 formed on the side surfaces thereof, and the inclined surfaces when the first and second gears 71 and 72 are rotated by contacting the inclined surfaces 714 and 724. Slip is generated by the 714 and 724 so that the first and second coupling holes 71 and 72 can be spaced apart from each other.

The casing 74 is shaped like a star, and has a rim 742 to which the boss 720 of the second coupler 72 is coupled, and a spring 75 that is protruded to the outside of the rim 742. It is composed of a plurality of spring holder 744.

The thickness of the casing 74 is formed to be equal to the length of the boss 720 of the second coupler 72.

A circular washer 73 is in close contact with the front end of the casing 74, and a disc 629 and a bearing 628 are arranged at the rear end.

Hereinafter, the combination and operation of the present invention having the above configuration will be described.

The second gear 612 is inserted into the outer circumference of the main shaft 62, and the first and second coupling holes 71 and 72, the washer 73, the casing 74 in which the spring 75 is built, and the disc ( 629, the bearing 628, the first joint 81 is sequentially coupled.

The second gear 612, the first and second coupling holes (71, 72), the washer (73), the casing (74) with the spring 75, disc (629), bearing (628), first Since the joints 81 are tightly coupled to each other, they can be integrally acted on, and these are referred to as drive trains T for convenience of description (see FIG. 5).

The drive train T is coupled to the free rotation without being fixed to the main shaft 62.

Thereafter, the second joint 82 is screwed to the main shaft 62 to be integrally coupled, and the second joint 82 is coupled to the first joint 81.

Therefore, when the second joint 82 is rotated, the drive train T including the first joint 81 is rotated.

As shown in FIG. 5, in the normal operation state, the motor 61 is driven to rotate the second gear 612 coupled with the first gear 611, and the drive including the second gear 612. The train T is co-rotated.

Thereafter, the second joint 82 coupled to the first joint 81 is rotated, and the main shaft 62 integrally coupled to the second joint 82 is rotated.

In addition, the third gear 83 integrally coupled to the second joint 82 is rotated, and the connecting means 63 coupled to the third gear 83 is driven so that the lower pulley 46 is rotated. The sub shaft 44 to which the pulley 46 is coupled is rotated so that the rack bar 42 is raised or lowered, and the water gate is also opened or closed.

On the other hand, if an overload occurs in the floodgate, the floodgate will not move even if the drive unit 6 is driven.

That is, since the rack unit 4 does not operate when the water gate does not move, the third gear 83 does not rotate, and the first and second joints 81 and 82 do not rotate.

In this case, as shown in FIG. 6, the first coupler 71 and the second coupler 72 constituting the overload protection device 7 are spaced apart while slipping.

When the second coupler 72 is moved, the spring 75 is compressed and spaced apart from the first coupler 71 so that the first coupler 71 is idling and no more power is transmitted to the second coupler 72. It is not blocked.

Therefore, when the overload protection device 7 is operated, a sensor (not shown) senses the movement of the second coupling port 72 and sends a signal to the controller, and the controller, which receives the signal, stops the operation of the motor 61. Send it.

By the operation of the overload protection device 7 it is possible to prevent damage to the drive train (T).

On the other hand, even if the second coupler 72 is spaced apart from the first coupler 71, the first gear 711 and the second gear 722 are always in contact with each other, and the second coupler 72 is in contact with each other. If the stopping force (overload state of the floodgate) is removed, it is immediately returned by the restoring force of the spring 75 and coupled with the first coupling port 71, thereby enabling power transmission.

On the other hand, the present invention is further provided with a manual operation unit to lift the rack bar 42 by cutting off the power of the motor 61 and manually driving the sub shaft 44.

The third gear 83 is integrally coupled to the second joint 82, and the second joint 82 is coupled to be integral with the main shaft 62.

Accordingly, when the second joint 82 is rotated in conjunction with the rotation of the first joint 81, the main shaft 62 may be rotated and the third gear 83 may be rotated.

Rotation of the third gear 83 rotates the connecting means 63 and enables the pulley 46 of the sub shaft 44 to rotate.

The first joint 81 is coupled to the main shaft 62 so as to be slidable, and a groove 814 is formed in the circumferential direction to which the end of the lever 84 is coupled to the outer circumferential surface.

The lever 84 is coupled to the outer housing 200 by a shaft pin so as to be rotatable, one end of which is coupled to the groove 814 of the first joint 81, and is operated by rotating the lever 84. The first joint 81 is moved along the main shaft 62 so that the first joint 81 is coupled to and separated from the second joint 82.

Therefore, when the first and second joints 81 and 82 are separated by the lever 84, the operation by transmission is interrupted.

Then, when the handle 88 is rotated, the main shaft 62 can be manually rotated by the combination of the first and second bevel gears 85 and 86, and the third gear 83 and the connecting means 63 By rotation, the rack unit 4 is driven to manually operate the water gate.
