In the hydrologic system having such a configuration, the base bed 11 of the hoisting unit 10 is configured between the two side hoisting case 27 and integrally attached to the brackets 7 on both sides of the top thereof with the hydrological gate 5 open. A sluice fixing device according to the present embodiment is provided to fix the sluice 5 by hooking the hooks 9 formed therein.

That is, in the configuration of the hydrological lock device according to the present embodiment, the hook lever 41 is hinged to the upper end of the hook lever 41 through the hinge unit HU on both sides of the base bed 11, respectively. The hook portion 43 is integrally formed at the lower end so as to hook the hooks 9 formed on both upper brackets 7 of the water gate 5.

Here, the hinge unit HU has hinge brackets 47 formed on both side cross frames 45 arranged in the longitudinal direction on both sides of the base bed 11, and penetrates the hinge brackets 47, respectively. The hinge pin 49 is installed. In addition, a cylindrical hinge housing 51 is integrally formed at an upper end of each of the hook levers 41, and a driven hinge gear 53 is integrally formed at an inner surface of the hinge housing 51 to form the hinge housing ( 51 and are fitted to each hinge pin (49).

Here, the gear unit 63 is made of a general gear combination to transmit the rotational force of the hook power motor 71 at right angles to the output shaft 65 therein, the description of the specific configuration is omitted.

Therefore, the operation of the hydrological lock device for the hydrological system having the configuration as described above will be described in detail with reference to FIGS.

That is, in the state where the hydrological lock is not used, as shown in FIG. 10, the hook lever 41 is positioned so as not to interfere with the vertical movement of the hydrologic gate 5 by rotating forward from a vertical angle.

In this state, when the water gate 5 is not used for a long time or when the water gate 5 needs to be kept open for a certain period of time for maintenance purposes, the water gate 5 is fixed to an open state. The drive motor 15 is driven in a forward direction in order to keep the opening state, and its rotational force is transmitted to the input sprocket 25 connected to the chain 23 to the output sprocket 21 via the gearbox 17.

Then, the rotational force passes through the input gear IG, the first driven gear PG1, the first reduction gear RG1, the second driven gear PG2, and the second reduction gear RG2 inside the reduction gear 13. While decelerating, the main shaft MS is rotated forward through the main gear MG engaged with the second reduction gear RG2.

In this way, in the open state of the water gate 5, the water gate fixing device has a chain 69 on the drive hook sprocket 67 through the gear unit 63 and the rotational force of the hook power motor 71 rotates in the forward direction. It is transmitted to the connected driven hook sprocket 61.

Then, the rotational force is transmitted to the hook power shaft 57 so that the hook power shaft 57 rotates, and the driven hinges 59 respectively configured at both ends of the hook power shaft 57 also rotate to engage each driven member. The hinge gear 53 rotates in one direction.

When the driven hinge gear 53 is rotated, the hinge housing 51 integrally formed with the driven hinge gear 53 is also rotated so that each hook lever 41 moves in a vertical line. Hook portion 43 formed at the lower end of the hook lever 41 is fitted to the hook ring 9 formed integrally with the bracket 7 on both sides of the upper end of the water gate (5).

Accordingly, the sluice 5 is in a state in which the hook portion 43 of the hook lever 41 is caught in the catching ring 9, thereby keeping its open state safely for a long time or a working time.

On the other hand, in order to release the operation of the hydrological lock device, the hook power motor 71 is rotated in the reverse direction, the rotational force is a driven hook sprocket connected to the chain 69 to the drive hook sprocket 67 via the gear unit 63 Forward to 61 is reversed.

Then, the reverse rotational force is transmitted to the hook power shaft 57 so that the hook power shaft 57 rotates in the reverse direction, and the driving hinge gears 59 respectively formed at both ends of the hook power shaft 57 also rotate in reverse direction. Each engaged hinge gear 53 is rotated in the other direction.

When the driven hinge gear 53 rotates in the other direction, the hinge housing 51 integrally formed with the driven hinge gear 53 also rotates so that each hook lever 41 moves forward from the vertical line. In the process, the hook portion 43 formed at the lower end of the hook lever 41 is released from the catch ring 43 formed integrally with the bracket 7 on both sides of the upper end of the sluice 5 to release the locked state.

Accordingly, the lock 5 is released from the hook 9 so that the hook lever 41 is released and becomes closed.

As described so far, the hydrological lock device for the hydrological system of the present invention discloses a structure in which the hook lever 41 is rotated by the electric drive by the drive motor 15, but is not particularly limited thereto. It may be a structure in which the reducer 13 itself is driven by electric or manual operation by employing a lever.

According to the hydrological lock device for the hydrological system of the present invention as described above, the hook lever is connected to each of the two sides on the base bed between the two sides of the lifting case, respectively, by a motor driving a predetermined angle around the hinge unit by a motor drive By rotating the hook part at the bottom to hook the hook formed on the gate, it is easy to fix when the gate is not used for a long time or the gate should be kept open for a certain period of time for maintenance purposes. It is effective to keep the state safe.
