Description

Automatic water level regulator {AUTOMATIC WATER LEVEL REGULATOR}

The present invention relates to an automatic water level control device, and more specifically, to an automatic water level control device in which the water level is automatically adjusted by the movement of a floating body while controlling the amount of water discharge by a gate that opens and closes by rotating around a hinge axis. .

Existing water gates use water level sensors to control the water level, so when the water level sensor malfunctions, there is a problem in water leakage due to water overflow, which can lead to accidents.

Conventional smart farm hydroponics has the disadvantage of having to periodically discharge the slurry accumulated at the bottom of the tank using an overflow weir, and has the disadvantage of having to be watered by a person due to the inflow of rainwater during rice paddy farming work.

In addition, the existing water purification plant filter paper drain valve is an automatic control system, which has the disadvantage of causing water to overflow due to malfunction of the drain valve during backwashing, causing a short circuit in the machine room and valve room on the lower floor.

Therefore, the existing method of automatically controlling the water level by linking the water level gauge and the valve when trying to keep the water level in the reservoir constant or below a certain level has problems with malfunction, and requires a person to directly check the water level and adjust the valve. There is a problem with conventional methods, such as man-made water openings, that they require a lot of labor.

Figure 3 is a side view showing a flap gate opened by a device that maintains a constant water level without water level control.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the attached drawings.

Figures 1, 2, and 3 are diagrams showing the automatic water level control device according to the present invention. Figure 1 shows the outlet (2) in a closed state, and Figure 2 shows the float when the water level rises according to the present invention. ) The rise of (80) indicates that the outlet (2) is opened by the flap gate (20) of the automatic water level control device, and Figure 3 shows a device that automatically maintains a constant water level by simply installing the floating body (80). .

The automatic water level control device according to the present invention includes a hinge part (10), a flap gate (20), a pulley pulley (30), a main pull cord (40), a pull cord lifting means (50), a pulley (60), and an auxiliary puller. It is composed of a rope (70), a floating body (80), and an auxiliary rope lifting means (90).

A reservoir refers to a structure with a space that can contain water, and the reservoir can be a concept that includes both artificial reservoirs and structures installed in nature to trap water and discharge it as needed.

The side wall (1) of the reservoir is a vertical wall with an outlet (2) formed at the bottom to allow water to escape, and the outlet (2) is the entrance to the drainage channel (3), which is a passage through which water drains from the reservoir. It plays a role.

The hinge portion 10 is a shaft extending in the horizontal direction, and the hinge portion 10 is fixedly installed on a portion of the side wall 1 of the water reservoir above the outlet 20.

The flap gate 20 is combined with the hinge part 10 and rotates up and down around the hinge part 10, and rotates downward to close the side wall of the reservoir (1) and the overlapping surface outlet (2), and Rotate to open the outlet (2).

The pulley pulley 30 has a fan-shaped shape that is coupled to the side opposite to the side facing the outlet 2 based on the state when the flap gate 20 blocks the outlet 2 among both sides of the flap gate 20. As a structure, the main pull cord 40 is inserted into the outer peripheral surface of the pull cord pulley 30, and a guide groove is formed to guide the movement of the main pull cord 40.

As shown in Figures 1 and 2, the pulley pulley 30 is configured so that the arc portion of the fan-shaped pulley pulley 30 faces downward when the flap gate 20 is closed, so that the flap gate 20 When (20) is in the closed state, a part of the main pull cord (40) is inserted into the guide groove of the pull cord pulley (30), so that the lower end of the main pull cord (40) is wound around the outer peripheral surface of the pull cord pulley (30). It is structured as possible.

As the main pull rope lifting means (50), existing pneumatic valves, actuators, etc. can be connected and used, and in some cases, a winch can be used.

The flap gate 20 is configured to apply a force applied to the straight line of the lifting means 50 as a rotational force through the pulley pulley 30.

The pulley 60 is a pulley fixedly coupled to the middle part of the main pull line 40, and can move while submerged in water, and moves up and down together with the main pull line 40 depending on whether the main pull line 40 is raised or lowered. It moves and functions to connect the movements of the auxiliary pull cord (70) and the main pull cord (40).

The auxiliary pull line lifting means (90) is installed on the water reservoir and one end of the auxiliary pulling line (70) is connected. When the floating body (80) rises and falls according to the water level, the auxiliary pull line lifting means (90) assists accordingly. It plays a role in controlling the target water level of the reservoir by pulling or releasing the pull line (70) to raise or lower the pulley (60).

If a fixed water level is desired in a smart farm, etc., it can be automatically adjusted using a floating body 80 without a lifting means as shown in FIG. 3.

The floating body 60 floats on water contained in the reservoir, and a ball made of plastic, etc. can be used as the floating body 60.

The floating body 60 usually floats on water, but in some cases, it may not necessarily float on the water but slightly submerge in the water. The floating body 60 has the power to float due to buoyancy, so when the water level rises as shown in FIG. 2, the auxiliary pull line 70 connected to the floating body 60 receives a force that is pulled upward by the floating body 60. , the part of the auxiliary pull cord (70) that surrounds the pulley (60) from below lifts the pulley (60) upward.

The auxiliary pull line (70) is a wire whose one end is connected to the auxiliary pull line lifting means (90) and the other end is connected to the floating body (60), and the auxiliary pull line (70) is connected to the auxiliary pull line lifting means (90). It extends downward from and is bent into a "U" shape with its middle portion surrounding the lower part of the pulley 60 and then installed to extend upward to the floating body 60.

When it is necessary to drain a large amount of water to replace the water in the reservoir or when heavy rain occurs and the flap gate (20) needs to be opened wide in a hurry, the flap gate (20) must be pulled and opened by the main pull line (40). The rope (40) needs to be made thick and strong, but the auxiliary pull rope (70) is used only for automatic water level control and does not directly pull the flap gate (20), but is attached to the main pull rope (30) according to the pulley principle. It can be made about 1/2 thinner than that.

The operation of the automatic water level control device according to the present invention configured as described above will be described as follows.

1 shows a state in which the flap gate 20 is rotated downward and overlaps the side wall 1 of the reservoir, and the outlet 2 is closed by the flap gate 20. At this time, the pressure of the water contained in the reservoir pushes the flap gate 20, thereby greatly improving the sealing force of the flap gate 20, thereby generating a reliable sealing force.

In this way, if it rains or water flows in while the outlet (2) is closed, the water level in the reservoir increases and it becomes necessary to discharge water. In order to use the water collected in the reservoir, it may be discharged through the drainage channel (3). Sometimes a need arises.

In particular, there are cases where it is important to keep the water level in the reservoir constant. For example, when farming rice fields, it is very important to keep the water level constant. In the case of rice paddy farming, if the water level is high, the crops will rot, and if the water level is low, they will dry out and die, so it is necessary to keep the water level constant.

The automatic water level control device according to the present invention is equipped with a floating body (80), an auxiliary pull line (70), an auxiliary pull rope lifting device (90), and a pulley (60) to automatically adjust the water level.

As shown in Figure 1, when the water level is low, the floating body 80, which floats on the water, is lowered significantly. Then, when the water level rises, the floating body 80 rises upward and pulls the auxiliary pull line 70. As a result, the pulley 60 moves up and the main pull line 40 pulls the flap gate 20, thereby opening the discharge port 2 and allowing the water to drain. When the water drains and the water level decreases, the floating body 80 goes down again and returns to the state shown in Figure 1. Through this action, the water level is automatically maintained at a constant level.

On the other hand, when it is necessary to discharge a large amount of water, the main pull line lifting means (50) is operated to pull the main pull line (40) upward and the flap gate (20) is rotated upward to discharge a large amount of water. do.

At this time, as the flap gate (20) is lifted, it pushes the sand and sludge settled on the bottom of the reservoir and also serves to create a hole through which water can pass. Therefore, if a lot of sediment is accumulated, the flap gate (20) is necessary. It is advisable to open it as much as possible so that the water can drain well.

3 is preferably installed in facilities such as smart farms that require a constant water level.

As in the above description, the present invention has been described only with respect to specific preferred examples, but it is clear to those skilled in the art that various changes and modifications are possible within the scope of the technical idea of the present invention based on the above specific examples, and such modifications It is natural that modifications and modifications fall within the scope of the appended claims.
