Description

[Technical field]

[0001] The present invention relates to a water gate, and more particularly to an opening and closing device that is opened and closed by rotating around a hinge axis. [Background technology]

[0002] Some existing floodgates open and close by sliding, and in the case of such floodgates, a structure for sliding is installed.

[0003] However, conventional sliding type floodgates are difficult to seal, and have problems such as malfunctions or water leakage due to foreign objects becoming stuck to the sliding structure and gate.

[0004] There are also conventional flap gate type floodgates, but these require complex structures or hydraulic devices to open and close the flap gates.

[0005] However, such existing methods for opening and closing flap gates have drawbacks in that they require a complex structure and there is a risk of oil leakage and breakdowns when hydraulic pressure is used for operation.

[0006] In addition, the sedimentation basin drainage valve of the existing water purification plant has a sliding type structure, which has the disadvantage that clogging occurs due to the adhesion of sand or slurry to the bottom of the water tank because there is no flow of slurry.

[0008] The present invention has been devised to solve the problems of the prior art. The present invention is a device that can crush settled sand or slurry by fluidizing it when the water gate is opened, making it easy to remove and discharge the slurry. It does not require a crushing device that is currently used separately in settling tanks, has a simple structure, and has excellent sealing power using water pressure, so there is no water leakage, so there is no waste of resources, energy is saved, and the purpose of the present invention is to provide a device that is easy to maintain and manage. [Means for solving the problem]

[0009] In order to achieve the above object, the water gate of the present invention is a device for opening and closing an outlet formed in a water storage section into which water is poured, thereby ensuring the drainage and stoppage of water from the water storage section, and includes a hinge section connected to the side wall of the water storage section above the outlet, a flap gate connected to the hinge section and rotating up and down around the hinge section, the flap gate rotating downward to close the outlet when it overlaps with the side wall of the water storage section and rotating upward to open the outlet, a fan-shaped pull cord pulley connected to the flap gate as a device for opening and closing the outlet by converting horizontal motion into rotational motion by vertical lifting means using a fan-shaped pull cord pulley attached to the flap gate, and a pull cord lifting means installed on the water storage section, and a pull cord having one end connected to the pull cord lifting means and the other end connected to the flap gate, with a part of the pull cord wound around the outer periphery of the pull cord pulley that moves so that the flap gate opens and closes the outlet.

[0010] It is also preferable to use a wire as the pull cord, or a chain for equipment that is deep in water and subject to heavy loads. Effect of the Invention

[0011] As described above, the floodgate of the present invention has the advantage that it has a more reliable sealing force and no water leakage due to the action of water pressure from the water reservoir, compared to conventional sliding structure floodgates, so there is no waste of resources, energy can be saved, and problems caused by foreign objects adhering to sliding structure structures are eliminated.

[0012] In addition, the water gate according to the present invention has the advantage of being less susceptible to breakdowns since it does not require complicated structures such as hydraulic devices.

[0013] In addition, the floodgate according to the present invention has the advantage that a separate crushing device is not required since the flap gate opens while stirring inward the sand or slurry accumulated at the bottom of the reservoir, pushing the sand or slurry settled in the reservoir and generating flow and cracks, thereby enabling the sand or slurry to be easily discharged. In addition, since it has the effect of enabling water to be easily discharged, a separate crushing device is not required. [Brief description of the drawings]

[0014] [Figure 1] FIG. 2 is a side view showing the state in which the flap gate is closed by the floodgate according to the present invention. [Diagram 2] FIG. 2 is a side view showing the state in which the flap gate is opened by the floodgate according to the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, specific embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0016] Figures 1 and 2 are schematic diagrams showing a floodgate according to the present invention, in which Figure 1 shows a state in which the outlet 2 is closed, and Figure 2 shows a state in which the outlet 2 is opened by a flap gate 20 of the floodgate according to the present invention.

[0017] The floodgate of the present invention comprises a hinge portion 10, a flap gate 20, a pulley 30, a pull cord 40 and a pull cord hoisting means 50.

[0018] A water reservoir refers to a structure having a space in which water can be stored, and includes a settling pond, a filtration pond, a discharge pond, etc. of a water purification plant, and may be a concept that includes all structures that trap water and discharge it as needed, such as dams, waterways, hydroponics, and fields.

[0019] The side wall 1 of the water storage section is a vertical wall having an outlet 2 formed at its lower part to allow water to drain, and the outlet 2 serves as the entrance of a drainage channel 3, which is a passage through which water drains from the water storage section.

[0020] The hinge portion 10 is an axis for rotating the flap gate 20, and is fixedly installed on a portion of the side wall 1 of the water storage portion that is above the discharge outlet 2.

[0021] The flap gate 20 is connected to the hinge part 10 and rotates up and down around the hinge part 10. When it rotates downward and overlaps with the side wall 1 of the water storage part, it closes the discharge port 2, and when it rotates upward, it opens the discharge port 2.

[0022] The pull string pulley 30 is a fan-shaped structure that is attached to one of the two sides of the flap gate 20, the side facing the discharge outlet 2 and the opposite side when the flap gate 20 is blocking the discharge outlet 2, and the outer circumferential surface of the pull string pulley 30 is formed with a guide groove or chain gear for inserting the pull string 40 therein to guide the movement of the pull string 40.

[0023] As shown in Figures 1 and 2, the pullstring pulley 30 is configured so that when the flap gate 20 is closed, the arc portion of the fan-shaped pullstring pulley 30 faces downward, so that when the flap gate 20 is closed, a portion of the pullstring 40 is inserted into the guide groove of the pullstring pulley 30 and the lower end of the pullstring 40 is wound around the outer circumferential surface of the pullstring pulley 30.

[0024] The pull string 40 is usually made of a wire. However, when the water level is deep, the strength of the wire may be insufficient, so in this case, a chain or the like may be selected. When the pull string 40 is made of a chain, the pull string pulley 30 is made of a chain gear.

[0025] The pull cord hoisting means 50 may be a pneumatic cylinder or actuator used in existing equipment, or in some cases a winch.

[0026] The operation of the floodgate according to the present invention constructed as above will now be described.

[0027] 1 shows the state in which the flap gate 20 is rotated downward to overlap with the side wall 1 of the water storage unit, and the discharge port 2 is closed by the flap gate 20. At this time, the pressure of the water contained in the water storage unit pushes the flap gate 20, so that the sealing force of the flap gate 20 is greatly improved and a reliable sealing force is generated.

[0028] In this manner, if it rains or water flows in while the drain outlet 2 is closed, the water level in the reservoir may rise and the water may need to be discharged, or the slurry that has accumulated in the reservoir may need to be discharged through the drainage channel 3.

[0029] In this case, as shown in FIG. 2, when the pull string 40 is pulled upward by operating the pull string lifting means 50, the pull string 40 lifts the pull string pulley 30 upward, causing the pull string pulley 30 and the flap gate 20 connected thereto to rotate upward.

[0030] This opens the drain outlet 2 that is blocked by the flap gate 20, allowing the water in the water storage section to be discharged through the drain outlet 2 and the drainage channel 3.

[0031] However, when the flap gate 20 is lifted, it lifts the sand and sludge that has settled at the bottom of the reservoir, and while fluidizing it, it also creates a gap through which water can pass, allowing the sediment and water to be efficiently discharged.

[0032] As described above, the present invention has been described only with reference to preferred specific examples. However, it will be apparent to those skilled in the art that various modifications and variations based on the specific examples can be made within the technical scope of the present invention, and it is to be understood that such modifications and variations fall within the scope of the appended claims. [Industrial Applicability]

[0033] This is a mechanism for discharging the liquid by installing a sluice gate at the bottom where the liquid is fresh water. Demand for replacements is expected to grow by providing complete sealing, energy savings and adequate quantities, such as replacing existing sliding gates.
