The present invention compensates for the shortcomings of manual or semi-automatic sluices installed in rivers, etc., to secure the quantity of water level selected by the manager, and to prevent secondary pollution of water quality by discharging fresh water to the lower part of sluice. do,

The present invention determines the opening and closing of the water gate by the water level sensor, and when the opening and closing of the water gate contracts and expands the hydraulic device by the hydraulic pressure generated by the hydraulic pump, the sluice connecting rod connected to the hydraulic piston has a linear reciprocating motion. The link between both sides of the gate is to open and close the gate when the hydraulic piston is inflated.

Description

Automated assistant doors {.}

It aims to automatically secure water for agricultural industry and prevent secondary pollution of water quality by discharging bottom part.

Agricultural water in rural areas and industrial water in factory areas are usually secured by building dikes in nearby rivers and installing underwater submarines, or by reducing small dams or reservoirs in mountainous areas.

These submerged beams, small dams, and reservoirs controlled the water supply by opening and closing manual or semi-automatic upright water gates when the water level was above a certain level. However, this has caused many lives and property damages due to inadequate response in case of emergency such as surprise rainfall or typhoon caused by sudden climate change.

The present invention compensates for these shortcomings in the prior art. If the water level detector is designated by the installer, the water level is automatically closed and the water gate is automatically closed for fresh water. Can be secured.

This design is an automatic guard gate device to secure water over a certain amount by desalination or discharge of the water level desired by the manager by the water level detector. When the gate is opened, the connecting rods formed on the top of the gate can be horizontally advanced by using hydraulic pressure. As the angle between the link between the two sides and the wing wall and the sluice increases gradually, the sluice rises due to water pressure. When the water gate is closed for fresh water, the connecting rod is horizontally retracted by the hydraulic system, and the link connected to the water gate and the wing wall moves the water gate downward and closes the water gate so that the water gate is closed.

Referring to the configuration and operation of the present invention based on the accompanying drawings as follows.

Figure 1 is a perspective view of the hydrological lock of the present invention, Figure 2 is a side view showing the state of the hydrology, Figure 3 is a side view of the open or closed water gate, Figure 4 is a side view of the fully open water gate and the like.

According to the components of the present invention, the guide grooves 11 installed at both upper end portions of the body 1 are connected to the water gate, and the connecting rods 12 embedded in the hydraulic piston 21 and the guide grooves 11 at the length thereof, and both blades. The bracket 32 is fixed to the upper end of the open wall 12, the bracket 41 fixed to both sides of the middle of the gate, the link 42 for connecting both brackets, the water gate 31 for opening and closing the water.

In addition, there is a door frame (51) to be able to withstand the water pressure is mounted on the water gate, water plate 52 to help the watertight gaps to help the watertight action.

In order to discharge water above the level specified by the water level sensor downstream, the hydraulic pressure of the hydraulic pump exits the hydraulic piston 12 side of the hydraulic system, and the hydraulic cylinder 22 enters the hydraulic piston 21 to move upstream. .

The connecting rod 12 of the sluice 31 is connected to the tip of the hydraulic piston 21, and the sluice connecting rod 12 is embedded in the guide groove 11. As the hydraulic piston 21 is advanced, when the sluice connecting rod 12 is embedded in the guide groove 11 and is horizontally advanced, the linkage connected to both wing walls 2 and the middle part of the sluice holds the sluice. The water gate will be opened by hydraulic pressure. That is, when advancing the upper end of the water gate horizontally upstream, the angle between the link wall and the water gate that hold the wing wall 2 and the middle side of the water gate gradually increases. At this time, the hydrostatic pressure of the link 42 is fixed to the down gate by the water pressure will be opened. (See FIG. 2, FIG. 3, FIG. 4) When the water level is too low to close the water gate 31 while reducing the discharge amount, the connecting rod 12 connected to the water gate moves downward along the guide groove 11 while the hydraulic piston is contracted. It will move horizontally.

At this time, as shown in Figure 2, the horizontal movement of the upper end of the sluice by the link connected to both the wing wall (2) and the middle of the sluice 41 is changed to the vertical movement at the lower end of the sluice 31, so that the sluice 31 is closed. . A closed series of operations of the water gate 31 can be easily seen with reference to FIGS. 4 to 3.

At this time, the index of the water gate uses a rubber index plate, and the lower portion of the water gate is inclined to coincide with each other in consideration of the bottom surface of the water gate 31 and the slope of the water gate.

In view of this, the principle of operation of the present invention is to change the horizontal movement of the upper end of the sluice by the hydraulic device when the door is opened and closed by the link connected to the wing wall 32 and the bracket 41 fixed to the sluice.

The present invention aims to make it possible to use the water resources, which are becoming important each day, in a clean state at a necessary time.

As we can see from the damage caused by conventional manual and semi-automatic upright gate installations, we have suffered a lot of loss of lives and property due to sudden surprises and floods.

The automatic flood gate device can control the freshwater by designating the water level at the administrator's automatic opening / closing of the gate.The discharge of the upper and lower sediments by the discharge of the lower part of the flood gate prevents secondary pollution of the water quality at the same time. It protects the ecosystem by forming fish paths, or fisheries.
