  The present invention is designed to overcome the existing technology by overemphasizing safety in hydrological technology, and to dramatically improve both efficiency, economical efficiency, and reliability, and to apply all or part of the present invention to all hydrologic devices. It is.

Description

Floodgate Equipped Hydraulic Driving Gear under Conventional level

The present invention relates to hydrology, which is a water level control device that is indispensable for dams, farms, tidal flats, estuaries, and more. It is related to the hydraulically driven low-gate hydrology, which combines with advanced technology, but the safety, reliability and convenience are greatly improved compared to the existing technology, and the manufacturing, installation, construction and operation costs are considerably lowered.

In general, hydrological gates are constructed in the dams, agricultural channels, tidal flats, and estuaries to control the level of water.

On the other hand, the damaging hydrologic gate has to be located at the top of the gate because all the operating equipment should be located at the top of the hydrologic gate. There is this.

Therefore, every sluice is accompanied by a separate large structure corresponding to the sluice.

The existing hydraulic hydraulic driving technology installs a hydraulic cylinder as long as the height of the cylinder type to the upper gate. The large structure and the long stroke cylinder are not only an obstacle for aesthetic appearance, but also the penetration of salt by sea wind in terms of function. If the hydraulic cylinder is damaged by the temperature difference reaching 50 ℃ due to dust, insects, microorganisms, and seasonal changes, and the gate is opened and closed halfway, the hydraulic cylinder will leak if the mechanical stopper is not installed. There is a disadvantage that the reliability of operation cannot be guaranteed.

In addition, in reality, when the gate is opened for several months, it is impossible to operate by hydraulic opening and closing, and expensive ceramic coating is performed in order to prevent the damage of the hydraulic cylinder.

 Although grease is applied to the surface of the cylinder to prevent the hydraulic cylinder contamination caused by the above-mentioned surroundings, it is not only temporary but also aesthetical because it causes discoloration and deterioration of the grease with the mixing of salt, microorganism and dust. There is an extremely disgusting problem.

The present invention for solving the above problems has the following purposes.

The purpose of the present invention is to uniformly disperse the structural stress acting on the hydrology and the structural stress acting on the water gate by the high-efficiency hydraulic actuator that combines the hydraulic device and the advanced mechanical drive device, which can remove the superstructure required for the installation of the existing regenerative water gate. The purpose is to provide a hydraulically driven low-gate hydrology to implement safety and economy.

The present invention for achieving the above object is a vertical slide type, and the hydrodynamic actuator consisting of the function of distributing the stress acting on the hydrology to multiple points and the rotational power generation using the hydraulic pressure, cyclone reduction and gear train The left side to allow vertical slide movement. Combining shrouds for urebars, multiple rollers, one or two roller directional guides, combined with hydraulic motors and cyclone reducers, and in a geartrain configuration, multiple hydro-operated sprockets have the same torque Which is rotated at a speed, both of which constitute a device for stopping

The above object is achieved by being composed of a gear structure, a moving stop, and a fixed stop at right angles when the acute angle is fixed, but driven by a spring and a displacement of the operating lever.

Hereinafter, with reference to the accompanying drawings, it will be described the detailed configuration of the hydraulically driven lower-gate gate according to the present invention.

In the accompanying drawings, Figure 1 is a simplified view of the water gate for explaining the structure of the hydraulic drive lowering type, the left and right hydraulic actuators (4) (5) by the vertical slide type lifting or lowering the low-level gate (1) The hydraulic pressure generated by the hydraulic generator V (2), so that the lifting bar (43) mounted on the left and right of the sluice can be raised and lowered by several parallel drive sprockets, and the left hydraulic actuator V ( 4) and the right side hydraulic driver V (5), the fluid energy is converted into the optimum mechanical driving force for hydrological operation.

At this time, the hydraulic balance control tube (6) to the right and left to send the same hydraulic pressure, if there is no power is driven by the hydraulic pressure generated from the manual hydraulic generator V (3). The operation of the hydrology and the power transmission relationship are manipulated by the main control board 7.

2 is a partially enlarged view for explaining the configuration of the hydraulic actuator V, which is operated under the same hydraulic pressure left and right and generates the same torque and rotation speed. The hydraulic pressure generated from the hydraulic generator V (2) is supplied to the hydraulic supply port 9, and when the cylinder is pushed downward, the shaft of the hydraulic motor crank chamber 8 is rotated, and this shaft is disengaged to the driving gear of the cyclone reduction gear. Directly connected to the reduction gear 12, the power is transmitted as it is. When the piston is pushed down from the hydraulic cylinder 11 of the hydraulic motor arranged by molding, the working oil is conveyed to the tank located under the hydraulic generator V 2 through the hydraulic outlet 10.

 The first reduction gear 13, which receives power from the primary reduction gear 12, is decelerated by the third reduction gear 14 corresponding to the sun gear, and then the first sprocket 24 for hydrological operation. The power is transmitted to the main drive gear 20 so that the second sprocket 26 can be powered. A stop gear box 16 is installed between the cyclone reducer 15 and the main drive gear 20 to fix the static stop state of the floodgate. It is composed of a stop gear 17 and a stop V (18) serves to fix the floodgate raised to a certain height.

 The first sprocket driving gear 23 connected to the main drive gear 20 is finally decelerated to drive the first sprocket 24 and the second sprocket driving gear 22 is directed through the intermediate gear 21. After switching, it can be connected to drive the gate in the same direction. Many of these sprockets equalize the force on the barreque to prevent breakage due to prolonged stress.

 3 is a partially enlarged view for explaining the configuration of the stopper, the stopper gear is an acute gear, which is moved by a stop angle 28 at an acute angle when lifting, but at a right angle the gear is stopped. The rotation of the stopper gear 17 is stopped by the fixed stop 27 fixed to the stopper gear box 16 while being caught by the portion. Fixing stop 27 is fixed by the pin is operated by its own weight. When the operation lever 31 is placed in the lifting position 32, it is automatically fixed when the ascending stop of the water gate is stopped. On the contrary, when it is placed in the lowered position 34, the disengagement spring 30 is pulled by the reversal of the lever, and the movement stop 28 is automatically dismantled by the tension of the spring when only a slight advance of the stopper gear 17 is made.

 4 is a partially enlarged view for explaining the configuration of the hydraulic generator V, the hydraulic oil stored in the hydraulic oil tank 35 is the hydraulic pump 39 by the coupling 42 directly connected to the axis of the drive motor 41 When driven, hydraulic oil is sucked from the hydraulic oil supply pipe 40 and passes through a pump to generate a high pressure fluid. When overpressure occurs due to mechanical abnormality, the hydraulic oil discharged through the spring-operated safety valve 38 is conveyed through the return line 37.

 5A and 5B are a plan view and a front view for showing a low-level hydrology made of a constitution of the present invention, in which both sides of the water gate are mounted with a barreque 43 having the same structure, and before and after the vertically vertical watermark of the hydrology The first roller guide 44 and the second roller guide 45, which enable movement, form a collar-like structure, which is combined with a hydroslide V 47 mounted on a civil structure for supporting a hydro gate. , The rollers are combined with the front rollers 48 and the rollers 50, which minimize the friction during the descent movement and distribute the force points to various places, and the barrec 43 is the same as the barrec housing 46. Combined.

The biggest advantage of the hydraulically driven low-level gate of the present invention, which is composed of the above configuration, is an economical technology that is not comparable to that of a radial gate because it does not require a hydrologic upper structure, but has a limitation in that a radial gate cannot be applied. have.

The vertical slide gate of the lower gate is mainly applied only to small gates (less than 4m × 5m), not because the gate itself is the limit, but because the top gate is the optimal structure for the large gate. Therefore, in the present invention, by applying at least five hydrodynamic bearings inside the slide casing to apply the vertical vertical slide hydrology, the stress acting on the one side one shaft of the radial is dispersed by several points. It not only strengthens the structural strength but also solves problems such as deformation.

For example, if there are 7 support bearings on both sides, there are 14 support bearings, so the two-point dispersion of stress in the radial type is 14 points in the vertical slide of the lower vertical type.

In the case of large floodgates, the center of gravity is very important when lifting or descending, so a specially designed recreational bar is mounted on both sides of the gate.

In addition, the hoisting machine applied to the lowering type combines an effective and reliable hydraulic rotary machine with high torque and a cyclone reducer that can significantly reduce the reduction ratio in terms of volume and weight, and improve the mechanical and hydraulic device technology. Combine strengths simultaneously to improve efficiency and reliability.

The device becomes more compact because the 10: 1 level can be switched to 250: 1 if the conventional reduction ratio is compared to the cyclone reduction ratio at the same volume. In addition, since the flow of energy is possible even if the flow of energy is not straight, it is easier to use space effectively. In particular, it is easy to operate several gates at the same time, and electricity is used only in the hydraulic unit, so there is no fear of leakage due to external exposure. In addition, all devices are enclosed, making it almost impossible for foreign particles to enter and the upper protruding space is almost negligible.

In addition, the unit of related power transmission unit has almost no possibility of failure, but it can be possible in a short time through unit replacement in case of failure or maintenance.

The present invention is a technique that can be applied in whole or in part to all hydrographs, from small to large, by using vertical slide movements of the hydrologic and related coupling techniques to distribute the stress applied to the hydrologic to several or dozens of points. The stress concentration can be avoided according to the fixed two-point type, and the superstructure is not required because of the lowering equation, which greatly improves the simplicity, reliability, and economics. The combination of the rotary hydraulic drive unit, cyclone reducer, and gear train is electric drive. Compared to the winch type, high torque and mechanical arrangements are free, and the volume of the hoisting machine itself is reduced by less than 50%, and the effect of simplicity and cylinder hydraulic actuating are exposed to salt, temperature difference, insects and microorganisms, causing frequent failures. And it is possible only for the reciprocating hydrologic gates, Since the hydraulic system itself should be at least 2.5 times the length of the gate, the present design has a 50 ~ 60% space reduction effect, a 30 ~ 40% construction cost reduction effect, and a 10 ~ 20% operating cost reduction effect compared to the existing equipment. It is obvious that this is a very useful design to obtain various effects.
