The present invention relates to a sluice that rotates and opens and closes a waterway by the power of a hydraulic drive device. In particular, when the waterway is closed by the closing operation of the sluice, it is safe to prevent the opening operation of the sluice even when hydraulic oil leaks from the driving device in an accident. It relates to a hydrologic drive with means.

In general, water dikes are constructed in rivers, reservoirs, swamps, etc. in order to limit the water to a certain flow path to prevent flooding of the water during flooding and to efficiently use water in the dry season.

A water channel is provided at a certain point of the dike, and a water gate is provided at the dike to control the amount of fresh water in the dike and the depth of the water.

1 and 2 is a prior art hydrology, and the application No. 10-2000-0065969, filed by the applicant of November 7, 2000, "automatically open and closed hydraulic cylinder built-in hydrology".

The water gates of FIGS. 1 and 2 are invented under the purpose of safe and trouble-free operation in water without being affected by water currents, and the hydraulic drive unit 2 and 4 are built in the hydrologic enclosure 3 so that the hydrological enclosure 3 is provided. After closing the drive device (2) (4) is characterized in that by operating the hydraulic pressure to open and close the gate, that is, rotation.

Such a sluice is very effective for underwater operation, especially in the case of the type of opening and closing the waterway (W) by rotating the sluice box (3) around the bottom as shown in FIG.

Here, the water gate of FIG. 2 is mainly installed in a reservoir where it is necessary to always dehydrate a certain amount of water, and when installing the type of rotating the hydrology enclosure 3 around the top of FIG.

However, the water gate of FIG. 2 supplies hydraulic fluid to the drive unit 2 and 4 to close the waterway W with the hydrology enclosure 3 so that the hydrology enclosure 3 is hydraulically supported so that the waterway W is closed. It is possible to maintain the state (see a of FIG. 2), in this case, if an accident occurs in the hydraulic pipelines and the hydraulic fluid leaks, even if the waterway (W) should be closed by the hydrology enclosure (3), the hydrology enclosure (4). ) Has a problem of opening due to the action of self-weight or water pressure (see b of FIG. 2).

First of all, in order to explain in detail the structure of the hydrological gate, the hydrological gate has a fixed shaft (1) installed across the channel (W) of the embankment (L), and the lower shaft is rotatably installed on the fixed shaft (1). It can be seen that it includes a hydrologic enclosure 3 for opening and closing W) and a drive device 2 and 4 installed inside the hydrologic enclosure 3 to rotate the hydrologic enclosure 3.

In this case, the driving device (2) (4) is a fixed arm (2) which is installed in the center of the fixed shaft (1) to the front, that is, the direction of water flow, the tip of the fixed arm (2) and the hydrologic enclosure (3) is composed of a hydraulic cylinder (4) which is connected both ends rotatably.

Next, (a) of FIG. 2 is a state in which the hydrology enclosure 3 is closed, and when it is seen, the piston rod is pulled out from the cylinder housing of the hydraulic cylinder 4 as much as possible by the supply of hydraulic oil so that the entire length thereof becomes the longest. , It can be seen that the waterway enclosure 3 rotated about the fixed shaft 1 by the hydraulic pressure is obliquely erected so that the waterway W is completely closed.

Afterwards, if you want to open the waterway (W), if necessary to remove the hydraulic pressure applied to the hydraulic cylinder (4), when the hydraulic pressure is removed from the hydraulic cylinder (4) piston rod enters into the cylinder housing of the hydraulic cylinder (4) And the hydro enclosure 3 is opened.

As this state is shown in Fig. 2B, it can be seen that the total length of the hydraulic cylinder 4 is the shortest and the waterway W is completely opened.

However, when the hydraulic pressure is removed from the hydraulic cylinder 4 in an accident in the state (a) of FIG. 2, the hydrological enclosure 3, which should close the waterway W, is inevitable due to the action of self-weight or hydraulic pressure as in FIG. 2 (b). There is a problem that is opened.

Of course, the hydraulic system of the sluice is usually to ensure the safety of the hydraulic line is automatically shut off by a known valve when the hydraulic fluid leaks, but the present invention is to be prepared in the event of failure or malfunction of the valve.

The present invention has been made to solve the problems of the prior art, when the hydrological enclosure is closed to operate the waterway is closed to limit the rotation for the opening operation of the hydrological enclosure, when the hydrological enclosure is opened to try to open the hydrological enclosure Safety means for releasing the limit of rotation for the operation In the closed state of the waterway, even if the hydraulic oil leaks from the hydraulic cylinder by accident, the hydrologic enclosure does not open due to the action of the weight or hydraulic pressure of the waterway enclosure. It is an object of the present invention to provide a hydrological drive that can prevent the.

Arranged in parallel so that both sides are rotatably connected to the hinge shaft 62 supported by the bracket on the rear inner surface of the hydrology enclosure 54 and the tip and hinge shaft 62 of the fixed arm 61, respectively. Hydraulic opening and closing cylinder 63 is included.

Here, the opening and closing hydraulic cylinder 63 is a double-acting hydraulic cylinder that works effectively in both directions, and the cylinder housing 63a and the piston rod 63b reciprocating linearly along the interior of the cylinder housing 63a. It consists of.

The driving device 60 is a hydraulic door 63 for opening and closing the hydraulic fluid 63 due to an accidental leakage of the hydraulic fluid by limiting the rotation for the opening operation of the water gate enclosure 54 when the waterway (W) is closed to the hydrology enclosure 54. Even if the enclosure 54 cannot be supported, the hydrology enclosure 54 is prevented from being opened by rotating by the action of its own weight or water pressure, and conversely, the hydrology enclosure 54 is opened when the waterway W is to be opened. It further comprises a safety means 70 for releasing the restriction of the rotation for the opening operation of the hydro lock 54.

The safety means (70) is a ratchet wheel (ratchet wheel) 71 is installed on the fixed shaft 52, and the lock pole is rotatably installed on the hydro lock 54 to be engaged with the ratchet wheel (71). (lock pawl) 72 and the hydraulic cylinder for the lock to push and rotate the lock pole 72 to engage the ratchet wheel 71 and the lock pole 72 when the waterway (W) is closed by the hydrology enclosure 54 (73), the elastic member (74) for rotating the lock pole (72) to the original position by reversely rotating the lock pole (72) when the force of the lock hydraulic cylinder (73) is removed, and the control unit (80) for controlling the drive source (73). It is composed of

Here, the ratchet wheel 71 is fitted around the fixed shaft 52 on one side of the fixed arm 61 and is firmly fixed with a key. The upper side of the ratchet wheel 71 is fitted with the lock pole 72 along the circumferential direction. A plurality of teeth 71a are formed to be bitten.

In addition, the lock pole 72 is supported by both sides to be rotatable by a bracket installed on the rear inner surface of the hydrology enclosure 54, one end of which protrudes toward the teeth 71a of the ratchet wheel 71. And the pawl portion 72a exerting the engaging action by being engaged between the teeth 71a by the action of the lock hydraulic cylinder 73 is engaged.

That is, the pawl portion 72a is inserted between the teeth 71a by entering the tooth end circle AC formed by connecting all the teeth 71a ends of the ratchet wheel 71 by the lock hydraulic cylinder 73. will be.

In addition, the lock hydraulic cylinder 73 is a single-acting thin cylinder that is effective in only one direction and has a short stroke. As with the opening and closing cylinder 63, the lock hydraulic cylinder 73 is provided with a cylinder housing 73a and a piston rod 73b. It is configured, and both ends are rotatably connected to the other end of the lock pole 72 and the bracket is installed on the rear inner surface of the hydro lock box (54).

In addition, the elastic member 74 is at least one tension coil spring, the both ends of the ratchet wheel 71 and the lock pole 72 is supported at both ends to the hydro lock box 54 and the lock pole 72 so as to be compressed. do.

On the other hand, the control unit 80 controls the operation of the lock hydraulic cylinder 73 and the opening and closing hydraulic cylinder 63 together.

In this safety means (70), the lock pole (72) is a stopper which abuts against the sluice body (54) to prevent excessive rotation by the lock hydraulic cylinder (73) facing the sluice body (54). The portion 72b is formed.

Reference numeral 55, which is not described above, is a rubber plate for watertight action when the waterway W is closed by the hydrology enclosure 54, and 56 is a shock absorbing member for alleviating the shock applied to the hydrology enclosure 54 in which the opening operation is completed. to be.

8A to 8D are views illustrating an operation process of the hydrological driving apparatus according to the present invention, and the operation of the present invention will be described below with reference to the drawings.

For reference, in FIGS. 8A to 8D, (A) is a view showing the operation of the opening and closing hydraulic cylinder 63, (B) is a view showing the operation of the safety means (70).

First, as shown in FIGS. 3 and 8A, the waterway W is completely closed with the hydro lock 54 (the ratchet wheel and the lock pole engage with the lock hydraulic cylinder by rotating the lock pole, thereby limiting the rotation of the hydro lock. If you want to open the waterway (W) in the) by operating the button of the operation portion, the hydraulic oil filled in the cylinder housing (73a) of the lock hydraulic cylinder 73 is removed to remove the force pushing the lock pole (72).

Therefore, the lock hydraulic cylinder 73 is not able to perform effective work, the lock pole 72 is rotated by the self-elasticity to be restored to the original shape of the elastic member 74 that was compressed to the ratchet wheel 71 and the lock pole The engagement of 72 is released.

At this time, as the ratchet wheel 71 and the lock pole 72 are released from each other, the limit of rotation for the opening operation of the hydro lock 54 is also released simultaneously (see FIG. 8B).

Next, under the control of the control unit 80, the hydraulic pump supplies the hydraulic oil in the hydraulic tank to the opening / closing hydraulic cylinder 63 to the inside of the cylinder housing 63a so that the total length of the opening / closing hydraulic cylinder 63 is shortened. The piston rod 63b enters.

Therefore, when the piston rod 63b enters, the linear movement of the piston rod 63b is converted into a rotational movement to the hydrologic enclosure 54 and transmitted because the fixed arm 61 connected to the end thereof is fixed to the fixed shaft 52. Therefore, the hydrologic enclosure 54 is opened and operated while slowly rotating in the " O " direction about the fixed shaft 52 as shown in FIG. 8C.

At this time, when the length of the opening / closing hydraulic cylinder 63 becomes the shortest, the hydrological enclosure 54 has its opening operation completed as shown by the solid line in FIG. 8C and the two-dot chain line in FIG. (W) is also fully open.

On the other hand, when the water channel W is to be closed, the piston rod 63b is pulled out of the interior of the cylinder housing 63a so that the total length of the hydraulic cylinder 63 for opening and closing is operated by operating the operation unit so that the hydrological enclosure 54 stands up. The lock door 54 is rotated in the direction "C" in FIG. 8C to be closed.

At this time, if the total length of the opening / closing hydraulic cylinder 63 becomes the longest, as shown in FIGS. 3 and 7B, the closing operation is completed, and thus, the waterway W is completely closed.

Next, under the control of the control unit 80, the hydraulic pump supplies the hydraulic oil of the hydraulic tank to the lock hydraulic cylinder 73 so that the piston rod 73b is supplied to the cylinder housing so that the overall length of the lock hydraulic cylinder 73 becomes longer. Pull out at (73a).

At this time, the lock pole 72 connected to the end of the piston rod 73b of the lock hydraulic cylinder 73 is rotated by compressing the elastic member 74, so that the pole portion 72a of the lock pole 72 is a ratchet wheel 71. It is interposed between the teeth 71a of the) and meshes with the ratchet wheel 71 (see Fig. 8A).

At this time, if the lock pole 72 can no longer rotate by the stopper portion 71b, the lock pole 72 is fully engaged with the latch wheel 71 and restricts the rotation for the opening operation of the hydro lock 54. Done.

Therefore, even when an accident occurs that the hydraulic fluid leaks from the hydraulic cylinder 63 for opening and closing, the hydrological enclosure 54 is opened by the ratchet wheel 71 and the lock pole 72 which limit the rotation of the hydrological enclosure 54. Operation is prevented.

Meanwhile, FIG. 8D is a view showing a state in which only part of the waterway W is closed. As shown in FIG. 8D, even when the opening and closing angle is changed by a plurality of teeth 71a on the circumferential surface of the ratchet wheel 71, It can be seen that the rotation of 54 can be limited.

In the present invention as described above, when the channel is closed, the ratchet wheel and the lock pole are engaged to limit rotation for the opening operation of the hydro lock, and when the channel is opened, the ratchet wheel and the lock pole are released to release the hydro lock. Since the opening and closing of the waterway can be achieved, even if the hydraulic cylinder leaking from the hydraulic cylinder supporting the hydrologic enclosure leaks due to accidental leakage of the hydraulic fluid, the hydrological enclosure cannot be opened. Therefore, there is an advantage that can be prevented from accidentally opening the waterway.

In addition, the present invention is to enable the ratchet wheel and the lock pole to be engaged at multiple angles by a plurality of teeth formed on the circumferential surface of the ratchet wheel, even when the waterway enclosure is completely closed with the hydro enclosure, even if the opening and closing angle of the hydrological enclosure is different. Likewise, there is an advantage that can limit the rotation for the opening operation of the hydro enclosure.
