Description

Drain lock {SEA DIKE SLUICE}

The present invention relates to a drainage lock installed in a drain or a drain at a downstream end of a dam or an estuary or a drainage passage,

More specifically, the structure of the drainage lock as well as the combined structure of the drainage lock and the lifting device are specially constructed so that the damage of the intermediate power transmission parts used to lift the drainage lock and lifting device as well as the drainage lock is minimized. To make maintenance very convenient,

Ultimately, the heavy heavy drainage lock allows the lift to descend correctly, smoothly and reliably under any circumstances, and closes while the lifting lock descends on its own while the lifting device stops operating. It relates to a high quality, high quality drainage door that prevents any trouble or trouble.

In general, drainage locks are installed in dams, estuaries, or drains at the downstream end of drainage channels, and the outflow water level is higher than the inland water during flooding. It is used to open and waterproof

For example, for tidal reclamation, the tidal flats are installed in tidal flats built in severe tidal flats, and are mainly used to drain the water in the reclaimed land to the sea during low tide.

Since the 1970s, Korea has been constructing large-scale drainage locks by constructing Asan Lake, Sapkyo Lake, and Youngsan Lake in the large-scale agricultural comprehensive development project. The Youngsan Lake lock, constructed in the latest (December 08, 1981), has a height of 13.6m, a width of 30m, and eight single doors, and the weight of one door is 480 tons. It is much larger than the 320 tons of known mid-sea reclamation and hexagonal floodgates in Japan.

The maximum flood drainage capacity of this drainage lock is 18,373m3 per second, and during the flood, 5,600 tons of floods per second are excluded to the sea to prevent flooding and to control the freshwater lake level.

In addition, Yeongsan Lake is the first gate in Korea to allow ships to enter and exit the lake, allowing 30-ton vessels to enter and exit freely regardless of the level difference.

As can be seen from the above, the drainage lock has a large overall size and a very heavy weight, and therefore, a large lifting force is required to lift the drainage lock.

It also must be lifted stably with the drainage lock leveling,

After lifting, the open state must be maintained continuously until drainage occurs.

However, it was not possible to develop and install a lifting device to satisfy these conditions with the conventional installation structure of the drainage lock.

In other words, in the conventional installation of the drainage lock and the lifting device, the drainage lock does not maintain a horizontal state because the connecting installation structure is too simple and the lifting force transmitted from the lifting device is not completely safe and accurate. If the drainage lock is distorted by rising and falling, it is necessary to cause the abnormality in the welding part of the drainage lock, the squeaking noise or the excessive force applied to the lifting device, or abnormal abrasion. In many cases, this resulted in shortening the occurrence and service life.

In addition, sometimes the drainage lock and lifting device are not raised or stopped in the middle due to a failure of the drainage lock and the lifting device due to such an installation structure, and the drainage lock is closed and lowered by itself. I always had a great setback or worry about.

On the other hand, in the case of the conventional lifting device, since the intermediate power transmission parts such as the wire or the rack bar used to lift the drainage lock are installed in the state of being exposed to the water or the outside, the damage is frequently performed. When necessary and some of the damage was confirmed, it was very difficult to maintain and practical, such as replacing the whole parts with new parts immediately for safety.

The present invention has been made in view of the above problems,

Specially constructed not only the structure of the drainage lock, but also the combined structure of the drainage lock and the mechanical lifting device to minimize the damage of the drainage lock and the mechanical lifting device as well as the intermediate lifting shaft member used to lift the drainage lock. To make it very convenient,

Ultimately, the heavy heavy drainage lock allows the lift to descend correctly, smoothly and reliably under any circumstances, and closes while the lifting lock descends on its own while the lifting device stops operating. Its purpose is to provide high-quality, high-quality drainage locks that do not cause any hindrance or trouble.

The drainage lock of the present invention for achieving the above object is basically a flood overflowing upwards than the water gate at both ends of the water gate coupled to both sides of the door frame for the hydrological coupling is installed in the dam or estuary or downstream end of the drainage The prevention jaw is formed in the upper end and the lower end forms a cylindrical hole in which foreign matter discharge holes are formed,

By fixing the lower end of the lifting shaft member installed in conjunction with the mechanical lifting device at the lower end of the cylindrical hole, the lifting shaft member is lifted and lowered using the mechanical lifting device, so that the water gate can be opened and closed up and down,

The lifting shaft member is a rack gear bar having a rack gear formed therein,

The mechanical lifting device installs the pinion gear coupled to the output shaft of the reducer to reduce the rotational force of the motor in the device installation base installed on the top of the sluice structure and transmits the rotational force of the pinion gear to the rack gear to operate the rack gear bar up and down. It is characterized in that the gate is configured to rise and fall.

The drainage lock of the present invention is basically formed on both sides of the sluice and the water overflow prevention jaw formed much higher than the upper surface of the sluice formed on the upper end of the cylindrical hole fixedly installed at the lower end of the rack gear bar is usually flooded with water or foreign matter Is basically blocked. Of course,

Even if foreign matters flow into the cylindrical hole together with water, it is immediately discharged through the foreign matter discharge hole formed at the bottom of the cylindrical hole, so that the gate is prevented from abnormally opening and closing operation.

In addition, the roller coupling groove formed on the surface supporting the water pressure of both sides of the water gate is detachably coupled to the roller assembled bearing, so that the installation and replacement of the roller is easy and the operation state is made smoothly.

In addition, since the sluice is formed in a hollow hollow form, the weight is less than the volume, and the water inflow portion of the sluice is formed in a curved shape so that the frictional resistance is reduced, thus making the sluice more easily lifted.

In addition, since the drainage lock of the present invention uses a plurality of high rate reducers, the water gate does not fall by itself due to its own weight even without a separate brake device.

In addition, the rack gear bar can be held in place by using a DOG DEVICE installed on the upper surface of the device installation base on the upper part of the hydrologic structure. Therefore, it is very convenient and safe for maintenance and inspection by disassembling or repairing various parts such as motor, reducer, and pinion gear.

In addition, if you want to check the hollow inside of the water gate, you can open the opening and closing lid of the internal inspection hole formed on both sides of the upper surface of the gate, and then go into the interior of the gate through the internal inspection hole to check the interior of the gate. .

On the other hand, the present invention is because the folding cover body formed to be able to adjust the length up and down on the outside of the rack gear bar constituting the lifting shaft member, the tree flowed down from the upstream side as well as during the opening and closing operation of the water gate as usual Foreign matter such as branches or small boulder does not directly touch the lifting shaft member, so abnormality in lifting and lowering of the gate or damage of the lifting shaft member are blocked.

In addition, when the lifting shaft member is composed of a rack gear bar, the gear teeth are formed on both sides of the groove with the H-shaped steel as the main pillar, and the rack gears 312 machined to the unit length are assembled and then bolted continuously. As it is manufactured by connecting to the installation, it is very stable because the lifting height is secured and sufficient strength is secured to lift the large heavy gate, so that the rack gear is easy to assemble and the coupling degree is very solid and precise. Smooth and easy to use since only one part can be replaced if any one of several rack gears is partially damaged in the future.

Therefore, it is clear that the drainage lock of the present invention is a very innovative invention that can be used safely and conveniently when reflecting the design.

The lower end of the folding cover body 400 is fixed to the lower end of the cylindrical hole 110,

When the rack gear bar 310 is raised and lowered, the folded cover body 400 is configured to be foldably folded inside the cylindrical hole 110.

On the other hand, the present invention is a single or a pair of fixed block 510 formed with a tooth (teeth) 511 on the inner surface to the upper surface of the device installation base 210 installed on the top of the hydrological structure (20) by hydraulic pneumatic or manually A dog device 500 configured to be movable is further fixedly installed.

Therefore, the teeth (teeth) of the fixed block 510 to the rack gear 312 of the rack gear bar 310 is raised and lowered by the rotation of the pinion gear 213 when opening and closing the gate 100 (511) ) Can be selectively engaged to secure the water gate 100 continuously and stably at a predetermined height.

In addition, the present invention has a roller coupling groove 120 is formed on the surface that receives the hydraulic pressure of the both ends of the water gate 100 is coupled to the door frame 10 for the hydrological coupling, slides in the roller coupling groove 120 In this way, the roller 121 in which the bearing is assembled is detachably coupled.

Therefore, the installation and replacement of the roller 121 is easy, as well as the lifting and lowering of the water gate 100 is made smoothly.

In addition, the sluice gate 100 is formed in a hollow hollow form to reduce the weight, both sides of the upper surface of the sluice 100 is provided with an opening and closing lid body 131 on the upper side to check and repair the inside of the hollow The internal inspection hole 130 is further formed.

In addition, the water inlet 140 of the water gate 100 is configured in a curved form for reducing the frictional resistance.

Although the present invention is not shown in the drawings, the rack gear 312 formed on the rack gear bar 310 constituting the lifting shaft member 300 is formed only on one side of the left and right sides, and also on the base of the device installation. The pinion gear 213 coupled to the output gear of the reducer 212 which decelerates the rotational force of the motor 211 fixedly installed at only one side of the 210 is engaged with the rack gear 312 to be placed as the pinion gear 213. It may be configured to operate the rack gear bar 310 provided with the size 312 up and down, so that the water gate 100 is raised and lowered.

On the other hand, the present invention as shown in Figure 6,

The water overflow preventing jaw 111 is formed at the upper end and the lower end of the cylindrical hole 110 formed at both ends of the water gate 100 so that the foreign matter discharge hole (?) Is fixed to the lower end of the installation portion ,

The lifting shaft member 300 is composed of a wire rope 320 in which the pulley 321 is installed,

The mechanical lifting device 200 is installed by the winding drum 223 coupled to the output shaft of the reducer 222 to reduce the rotational force of the motor 221 on the device installation base 210 installed on the hydrologic structure 20 By constructing a mechanical lifting device 200,

By winding the wire rope 320 by the rotational force of the winding drum 223 may be manufactured so that the water gate 100 is raised, lowered.

The drainage lock according to the present invention constituted as described above includes a rack gear bar 310 having the rack gears 312 formed on both sides of the lifting shaft member 300, as shown in FIGS.

The rack gear bar 310 is coupled to the output shaft of the reducer 212 which decelerates the rotational force of the motor 211 vertically and vertically on both sides of the device installation base 210 installed on the hydrologic structure 20. It is the most preferable configuration to be configured to raise and lower the gate 100 by using the mechanical lifting device 200 is inserted between the (213) and the rack gear 312 is configured to engage the pinion gear 213. The following describes the operating state based on such a configuration.

First, the drainage lock of the present invention is formed on both sides of the sluice gate 100 and the water overflow prevention jaw formed much higher than the upper surface of the sluice gate 100 at the upper end of the cylindrical hole 110 is fixed to the lower end of the rack gear bar 310 Since 111 is formed, it is fundamentally blocked from overflowing water or foreign matter in normal times.

However, even if water overflows, it is immediately discharged through the foreign matter discharge hole () formed in the bottom of the cylindrical hole (110).

In such a state, when it is necessary to lift and drain the water gate 100 which normally blocks the drain hole as necessary, and the motor 211 is operated, the rotational force generated from the motor 211 is a high ratio reducer 212. It is decelerated by the transmission force is increased to rotate the pinion gear 213 coupled to the output shaft.

At this time, since the plurality of vertical gears 213 are installed vertically on both sides of the base 210 for installing the device, these pinion gears 213 rotate upward from both sides.

The rotational force of the pinion gear 213 is transmitted to the rack gear 312 in which both sides are engaged, and the rack gear bar 310 is raised.

Then, since the lower end of the rack gear bar 310 is fixed to the cylindrical hole 110 formed on both sides of the sluice 100, the sluice gate 100 is raised and lowered at the same time.

The drainage is then opened and drainage proceeds.

At this time, the roller coupling groove 120 formed on the surface supporting the hydraulic pressure of the both ends of the sluice 100 is coupled to the roller 121, the bearing is assembled, the operation state is made smoothly,

In addition, since the water gate 100 is formed in a hollow hollow form, the weight is less than the volume, and the water inlet 140 of the water gate 100 is formed in a curved shape, so that the frictional resistance is reduced and the salvage is reduced. It's easier to do.

The drainage lock according to the present invention has a plurality of high rate reducers 212 even when the water gate 100 is lifted and lifted in such a manner so that the motor 211 is temporarily disabled due to an operator's mistake or power failure. As it is used, it does not fall by the weight of the gate even without a separate brake device.

However, the state of lifting and lowering the water gate 100 to a certain height in order to not overwhelm the motor 211 or to check and replace the motor 211 or other various parts in case of such an emergency occurs. If it is necessary to maintain a stable stably so as not to move the rack gear bar 310 by using a dog device (DOG DEVICE) 500 is installed on the upper surface of the device installation base 210 of the upper surface of the sluice structure 20 in advance. Hold it.

That is, the toothed teeth (511) formed on the inner surface of the fixed block 510 by advancing a pair of fixed blocks 510 provided in the dog device (DOG DEVICE) 500 manually or by a rack gear bar The rack gear 312 of the 310 to engage with the rack gear bar 310 is to be held stably so as not to move.

In this state, since the water gate 100 does not fall at all, it is safe to disassemble and repair or replace various parts such as the motor 211, the reducer 212, the pinion gear 213, and the like.

At this time, if you want to check the hollow hollow inside of the water gate 100, open the opening and closing lid body 131 of the internal inspection hole 130 formed on both sides of the upper surface of the water gate 100, and then through the internal inspection hole 130 (100) Go inside and check.

When all of the drainage is made in the state in which the water gate 100 is raised or repaired or replaced, the pair of fixed blocks 510 provided in the dog device 500 may be pneumatically or manually. By reversing, the teeth (teeth) 511 formed on the inner side of the fixed block 510 are engaged with the rack gear 312 of the rack gear bar 310.

Then, when the motor 211 is reversely rotated, the rotational force is decelerated by the high ratio reducer 212, and the transmission force increases to rotate the pinion gear 213 coupled to the output shaft.

At this time, since the pinion gear 213 is installed vertically on both sides of the device mounting base 210, these pinion gears 213 rotate downward from both sides.

Then, the rotational force of the pinion gear 213 is transmitted to the rack gear 312 in which both sides are engaged, and the rack gear bar 310 descends and the water gate 100 also descends safely.

On the other hand, in the present invention, since the folded cover body 400 formed to be able to adjust the length of the up and down on the outside of the rack gear bar 310 constituting the lifting shaft member 300, the sluice 100 is normally closed Of course, even when opening and closing operation of the water gate 100 to prevent foreign substances such as twigs and small boulder flowed down from the upstream side directly to the lifting shaft member 300 to cause abnormality in the lifting operation of the water gate 100 or lifted Damage to the shaft member 300 is blocked beforehand.

In addition, in the present invention, when the lifting shaft member 300 is composed of the rack gear bar 310, the gear teeth in the cross section of the grooves on both sides with the H-shaped steel 311 as the main pillar to produce the rack gear bar 310. And then assembled by mounting the rack gear (312) machined to the unit length and then continuously connected and installed with bolts (313) to secure a high enough lifting height and high strength heavy salvage It is stable when reflecting design,

The rack gear 312 is easy to assemble and the coupling degree is very solid and precise, so the water gate 100 opening and closing operation is smooth,

In case of partial component failure in the future, it is very convenient to use because only the component can be partially replaced.
