Description

WATER LEVEL AUTOMATIC CONTROL DEVICE FOR FLOOD-GATE}

The present invention relates to a water level control device for irrigation canals, rivers and reservoirs, more specifically, to more than the set water level in the water management of irrigation canals, rivers and reservoirs (hereinafter referred to as 'waterway') When the water level is reached or when the water level is lower than the set level, the water gate is automatically opened or closed to control and store the required amount of water at all times, thus maximizing the convenience of water management and always keeping the amount of water at a certain amount. It relates to a water level automatic control device for automatically regulating and storing.

In general, irrigation canals, rivers and reservoirs are used for the purpose of storing a certain amount of water for proper use in farmland management or irrigation water.

In the water management of such waterways, water is continuously stored in case of drought and used when needed. When the amount of water reaches more than necessary level due to rain, the water gate installed on the embankment to prevent damage such as flooding The water is discharged by the opening operation of the device, and when it is discharged more than necessary, the water is re-stored in the waterway by the closing operation of the hydrological device.

In such a conventional hydrological device, there is a method in which a manager raises and lowers the water gate by directly rotating and turning the spindle directly by a handle operation, but this is utilized only for a small capacity with a small amount of water in the waterway, Its use is very limited due to a lot of labor and time.

Thus, in recent years, the pinion gear is rotated by the hoisting unit to raise the fixed rack bar connected to the center or both sides of the gate to open the gate, and when the gate is closed, it is lowered by the weight of the elevated gate, that is, a separate brake. It is known that a means of preventing the reverse rotation of the pinion gear by the means and maintaining the open state by closing the water gate by the reverse rotation of the pinion gear with its own weight by releasing the brake means closes the discharge passage of the waterway.

However, such a hydrological device is also very cumbersome by the administrator monitoring the water level of the channel one by one and opening and reclosing the water gate by the operation of the hoisting unit when the water level becomes higher than the low water level. In the case, the water could not be discharged at the proper level of the water channel and suddenly discharged a large amount of water at a time, so that the effective flood management was not provided due to the large impact on the surrounding flood such as farmland.

In addition, when the drought does not rain, no water is discharged, but if a large amount of water is stored in a sudden heavy rain or the like, an appropriate amount of water cannot be discharged through the water gate before reaching the manager's hand, If the furnace overflow occurs and the organic residues deposited on the bottom of the channel are not provided and are cured, the internal water temperature is increased, thereby causing serious contamination of the channel.

For this reason, in the water management of the channel, the discharge level or the storage level should be achieved by opening and closing the water gate according to the situation of the channel, but most of them provide the discharge level based on the volume of the channel. In the present situation where the manpower required for the operation of the liberty by the manager must wait, the present situation was very difficult in our country.

On the other hand, automatic floodgates have been provided recently, but this method has a disadvantage that manual operation is difficult and cannot be quickly dealt with in case of failure, and the repair can be performed only after the water supply of the waterway is sufficiently reduced. In addition, as disclosed in Japanese Unexamined Patent Application Publication No. 3-55308, a device is disclosed that proportionally opens and closes a water gate by using a float and a height is displaced according to the water level. A gate for opening and closing on the water channel is provided, and the upstream water purifier, the float chamber, and the downstream water purifier are separately provided on the adjacent side thereof, and the upstream and upstream water purifiers are communicated with each other, and the downstream downstream and the Kate water purifier are connected. The float chamber is provided with a float that interlocks with the lifting operation of the kate. The upper distribution port is provided with a higher distribution port of a higher position, and the upper distribution port communicates with the upper and lower distribution ports with a diameter smaller than the communicating diameter, and the float chamber and the downstream water purifier are connected to an outlet pipe and float. It is installed to abolish the deformed body operated by the buoyancy of the water.This flows into the float chamber through the upper communication port and the water flows into the lower communication port level of the upstream reservoir. In addition, when water flows into the float chamber above the level of the upper communication port at a position higher than the lower communication port of the upstream reservoir, the float of the float chamber starts to rise due to the inflow amount, and the water gate rises as the float rises. That is, the channel is opened, that is, the float rises according to the water level flowing into the float chamber. For example, in the event of an emergency such as a flood, the water flows into the downstream reservoir, causing the debris to abolish the outflow duct, thereby rapidly increasing the level of the float chamber to open the floodgate quickly. This is a problem in that the water gate is proportionally opened and closed according to the rising and falling of the float separate from the existing water gate. This lifting and lowering operation makes it difficult to open and close the gate even when an abnormality occurs in any one of the linking operating portions, and in particular, manual operation in an emergency is very difficult. It is difficult to adjust the point of view, and for this purpose, it is necessary to reinstall to adjust the height of the upper and lower communication ports. In addition, it is very difficult to control the opening degree of the water gate according to the situation in the high and low water level, and in order to do this, it is necessary to adjust the length of the wire for lifting the water gate according to the elevation of the float. Of course, there is a problem that accurate control becomes difficult.

An object of the present invention has been researched and developed to effectively solve the above disadvantages of the prior art,

The present invention provides a simple structure to automatically open or close the water gate automatically when the water level reaches the water level higher than or equal to the set water level, or to automatically adjust the amount of water required at all times. In particular, it is possible to maximize the reliability of the operation by electrically controlling the opening and closing operation of the water gate according to the water level as well as to be able to open and close the water gate manually in an emergency.

In addition, an object of the present invention is to maximize the compatibility of the device by adjusting the high water level and the low water level of the discharge level according to the situation of the channel, regardless of the volume of the channel.

The above object of the present invention is provided in the water channel and the water level level detection means for detecting and detecting the high water level and the low water level of the water discharge level of the water discharge level, and the water level level detection means electrically connected to the high water level detection or low water level detection By a control unit operated by the control unit and a winding unit for opening or closing the gate by the control signal of the control unit.
