Description

Technology Field

[0001] The present invention relates to a non-powered automatic control system for supplying water underground, and more specifically, to an underground culvert system using a non-powered automatic control device for underground drainage / water supply that can reduce the time, manpower, and management costs for irrigation by automatically supplying and cutting off agricultural water underground without power according to changes in the groundwater level of agricultural land such as rice paddies or fields. Background Technology

[0002] In general, agricultural land where crops are cultivated, such as reclaimed land, rice paddies, and fields, must be supplied with sufficient water necessary for the growth of crops.

[0003] To create such an environment, irrigation facilities that supply water and drainage facilities that discharge excess water are typically installed.

[0004] Recently, to artificially ensure a smooth supply of agricultural water within a specific area of ​​farmland, perforated pipes are primarily installed after excavating the ground with equipment such as backhoes.

[0005] In other words, to utilize water from reservoirs, rivers, or groundwater for agricultural purposes, the bottom of the farmland is excavated and perforated pipes are buried; then, when needed, water is pumped out using a water pump and supplied through the pipes in the required amount.

[0006] This method minimizes the loss of agricultural water and enables the easy supply of agricultural water to a certain area.

[0007] However, there is a problem of very low efficiency because irrigation work requires a significant amount of time and manpower, such as having to focus on preventing drying by irrigating the entire farmland during droughts and ensuring thorough drainage to prevent crops from rotting during the rainy season.

[0008] In addition, if proper water management involving adequate irrigation is not carried out, there is a problem that hinders the growth of crops.

[0009] For example, when heavy rains cause rainwater to fall underground and water flowing in from adjacent areas accumulates without draining into the lower layers, flooding farmland and submerging crops, it leads to oxygen deficiency that prevents photosynthesis. Consequently, substrates are consumed by anaerobic respiration, often resulting in the plants dying. Furthermore, even after drainage, diseases are prone to occur, causing significant damage such as impacts on yield and quality.

[0010] It is stated that the background technology or prior art described herein refers to information possessed by the inventor or acquired during the process of deriving and completing the present invention, and is specified merely to aid in understanding the technical significance of the present invention and to be useful for prior art search and examination, and does not mean technology that was generally known and widely used in the technical field to which the invention belongs prior to the filing of the present invention. Prior art literature

[0011] KR 10-0897533 B1 2009. 05. 07.KR 10-0450908 B1 2004. 09. 20. The problem to be solved

[0012] Accordingly, the inventors have devised the present invention as a result of continuous research and strenuous efforts to develop a new non-powered culvert automatic control system. This system is designed to reduce the time, labor, and management costs associated with irrigation by comprehensively considering the aforementioned factors and seeking to resolve the technical limitations and problems inherent in existing irrigation methods. Specifically, it aims to automatically drain water through culverts to prevent crop roots from being submerged when the groundwater level rises due to heavy rainfall, and conversely, to automatically control and supply the agricultural water required for crops when the groundwater level is low. Furthermore, it seeks to minimize the waste of agricultural water and crop damage caused by excessive water supply.

[0013] Therefore, the technical problem and objective of the present invention is to provide an underground culvert system using a non-powered automatic control device for underground drainage / water supply that enables the automatic supply and cutoff of agricultural water into the ground without power in accordance with changes in the groundwater level of agricultural land.

[0014] Another technical problem and objective of the present invention is to provide an underground culvert system using a non-powered automatic control device for underground drainage / water supply that can minimize waste and crop damage caused by the oversupply of agricultural water.

[0015] The technical problems and objectives that the present invention aims to solve are not limited to those mentioned above, and other unmentioned technical problems and objectives will be clearly understood by those skilled in the art from the description below. means of solving the problem

[0016] A specific means according to an aspect of the present invention for effectively achieving a specific technical purpose while embodying a new concept to solve the technical problem of the present invention as described above is presented as a non-powered automatic control system for a culvert, characterized by employing a perforated pipe culvert laid underground and having a plurality of water holes drilled on its perimeter surface to supply water underground, a water supply device that supplies and blocks water flowing in from the outside to the perforated pipe culvert, and a groundwater inflow pipe installed underground in the ground where the perforated pipe culvert is laid and connected to the water supply device.

[0017] Specifically, the water supply device comprises: a valve casing formed with an inlet for water inflow and at least one outlet for water discharge; a cylinder installed so as to communicate with the interior and upper end of the valve casing and with the lower end communicating with the groundwater inflow pipe; a valve disc mounted on the upper end of the cylinder, which opens and closes the inlet through vertical movement to prevent water from flowing into the interior of the valve casing through the inlet and being discharged through the outlet, or to block water from flowing into the interior of the valve casing through the inlet; and a float that operates the valve disc by rising and falling due to buoyancy when water flows into the cylinder through the groundwater inflow pipe according to changes in the groundwater level of the land where the perforated culvert is laid.

[0018] Thus, the present invention blocks the supply of agricultural water into the ground of the farmland through perforated pipes when the groundwater level of the farmland rises, and can automatically supply agricultural water necessary for crops only when the groundwater level of the farmland is low.

[0019] In addition, as a preferred aspect of the present invention, a valve seat may be formed around the inlet of the valve casing to maintain a seal by closely contacting the upper surface of the valve disc.

[0020] In addition, a preferred aspect of the present invention may further comprise an aggregate layer laid and covering the upper part of the perforated pipe culvert in the ground and a fiber layer laid on the lower part of the perforated pipe culvert to ensure smooth water supply from the perforated pipe culvert into the ground. Effects of the invention

[0021] According to an embodiment implementing the technical concept on which a unique solution means is based to solve the technical problem of the present invention, when the groundwater level of agricultural land rises above a predetermined reference level due to water supplied from an irrigation channel, the valve disc automatically closes the inlet by the buoyancy acting on the float, thereby automatically blocking the agricultural water supplied into the ground through the perforated pipe culvert.

[0022] Therefore, it is possible to prevent the waste of oversupplying agricultural water to farmland and minimize waterlogging damage to crops.

[0023] In addition, by automatically controlling the supply and cut off of agricultural water required for crops without power according to the groundwater level, time, labor, and management costs for irrigation can be reduced.

[0024] The effects of the present invention are not limited to those mentioned above, and other unmentioned effects will be clearly understood by those skilled in the art from the description in the claims. Brief explanation of the drawing

[0034] [Specific implementation form]

[0035] An underground culvert system using a non-powered automatic control device for underground drainage / water supply according to an embodiment of the present invention includes a perforated pipe culvert (10), a water supply device (20), and an underground water inflow pipe (30), as shown in FIGS. 1 to 3.

[0036] Perforated pipe culvert (10)It is laid at regular intervals in the ground (G) to drain excess water that seeps into the ground (G) during the rainy season and to supply water that is lacking to crops during the dry season.

[0037] That is, the perforated pipe culvert (10) is installed at a certain depth in the ground of the farmland with a gradient so that water can be supplied naturally and smoothly from the water supply device (20) during the dry season.

[0038] And, a plurality of water holes (11) are drilled in the perimeter of the perforated pipe culvert (10) to ensure a smooth supply of water.

[0039] In addition, the perforated pipe culverts (10) can be arranged in parallel rows with a certain spacing between them, or arranged in a zigzag shape rather than in a straight line.

[0040] Here, the perforated pipe culvert (10) can be formed as a single common pipe structure in which the ends of a plurality of thin branch pipes are connected and fixed to a header (12) connected to a water supply device (20).

[0041] Additionally, the perforated pipe culvert (10) may be formed with multiple water holes (11) drilled on its circumference and stacked in layers with different diameters.

[0042] Meanwhile, the perforated pipe culvert (10) is provided in a form in which several water holes (11) with a diameter of 1 to 5 mm are arranged on the circumference of a hard or soft plastic pipe, so that water can be irrigated uniformly even at low water pressure.

[0043] water supply device (20) It serves to supply and block water flowing in from the outside to the perforated pipe culvert (10).

[0044] Specifically, the water supply device (20) is configured to include a valve casing (21), a cylinder (24), a valve disc (25), a float (26), a valve seat (28), and a valve stem (29).

[0045] The valve casing (21) has an inlet (22) for water to enter and at least one outlet (23) for water to be discharged.

[0046] The cylinder (24) is installed so that its upper end communicates with the inside of the valve casing (21) and its lower end communicates with the groundwater inflow pipe (30) to guide the lifting and lowering of the valve disc (25).

[0047] The valve disc (25) is positioned on the upper part of the cylinder (24) while being fixed to the upper part of the valve stem (29) to open and close the inlet port (22) according to the movement.

[0048] That is, the valve disc (25) opens and closes the inlet (22) by moving up and down, thereby preventing water from flowing into the interior of the valve casing (21) through the inlet (22) and being discharged through the outlet (23), or blocking water from flowing into the interior of the valve casing (21) through the inlet (22).

[0049] The float (26) acts to operate the valve disc (25) by moving up and down due to buoyancy when water flows into the lower part of the cylinder (24) through the groundwater inflow pipe (30) in accordance with the change in the groundwater level of the ground surface (S) where the perforated pipe culvert (10) is laid.

[0050] Here, the float (26) can be formed as a sealed cylindrical fan filled with air to have buoyancy that rises to the top of the cylinder (24).

[0051] The valve seat (28) is formed around the inlet (22) of the valve casing (21) so that the valve surface (27) of the valve disc (25) is in close contact to maintain a seal.

[0052] The valve stem (29) connects the valve disc (25) and the float (26) to prevent the valve surface (27) of the valve disc (25) and the valve seat (28) from being in close contact.

[0053] And a knob (29a) is integrally formed on the upper part of the valve stem (29) to artificially open and close the valve disc (25) while preventing the float (26) from going down below a certain height inside the cylinder (24).

[0054] groundwater inflow pipe (30) It serves to supply rainwater that falls on the surface and water supplied from the water supply channel to the lower part of the cylinder (24) of the water supply device (20) without being drained and accumulating underground.

[0055] That is, the groundwater inflow pipe (30) is installed horizontally in the underground area where the perforated pipe culvert (10) is laid, with one end connected to the water supply device (20).

[0056] Meanwhile, in order to ensure smooth water supply from the perforated pipe culvert (10) to the ground (G), an aggregate layer (40) may be formed by laying and covering the upper part of the perforated pipe culvert (10) in the ground (G) with aggregate such as sand or gravel.

[0057] In addition, to prevent high-salinity water or salt from rising to the surface of the ground (G), a fiber layer (50) may be formed by laying a fiber board made of plant fibers and compression molded, or a non-woven fabric with fine pores, at the bottom of the perforated pipe culvert (10) in the ground (G).

[0058] Here, examples of the fiber layer (50) may include a nonwoven fabric (filter mat) that has excellent high strength, permeability coefficient, durability, and chemical resistance and is used for the purposes of drainage induction, erosion prevention, ground reinforcement, and uniform settlement; a soft ground mat (PP / PET mat) that has a uniform structure and excellent mechanical function to separate soft ground and high-quality embankment material and prevent uneven settlement of the ground; and a waterproofing mat (coating mat) that integrates a waterproofing sheet and a nonwoven fabric to block leakage.

[0059] The main operation and operating principles of an underground culvert system using a non-powered automatic control device for underground drainage / water supply according to an embodiment of the present invention configured as described above are as follows.

[0060] First, as shown in FIG. 3, if there is no standing water underground, the float (26) descends and operates the valve disc (25), causing the valve surface (27) to separate from the valve seat (28) and remain in an open state.

[0061] That is, when the groundwater level of the farmland drops below a set reference level, the valve disc (25) automatically opens the inlet (22) to supply agricultural water into the ground through the outlet (23) and the perforated pipe culvert (10).

[0062] Conversely, as illustrated in FIG. 4, when rainwater seeping into the ground and water flowing from adjacent areas such as waterways seep into the ground and accumulate, water naturally flows into the interior of the cylinder (24) through the groundwater inflow pipe (30). When this happens, the float (26) rises due to buoyancy and operates the valve disc (25), causing the valve surface (27) to adhere to the valve seat (28) and maintain a sealed state.

[0063] That is, when the groundwater level of the farmland rises above a set reference level, the valve disc (25) automatically closes the inlet (22) by the buoyancy acting on the float (26), thereby blocking the agricultural water supplied into the ground through the perforated pipe culvert (10).

[0064] FIG. 6 shows that, as another example according to the present invention, a drainage device (80) for forcibly draining the groundwater level when the groundwater level is high because the underground components formed in the ground are mixed with irregular density and the groundwater level cannot be maintained uniformly over the entire area, a drainage pipe culvert (70) connected to a perforated pipe culvert (10) for draining through the drainage device (80), and a buoy (90) that rises or falls according to the water level and operates the drainage device (80) when it rises.

[0065] The drain pipe culvert (70) is installed so that the exposed ends of the perforated pipe culvert (10) are each connected, and during drainage operation, it is configured to allow water to flow into or be introduced into the perforated pipe culvert (10) for drainage.

[0066] The drainage device (80) may be of a manual or electric mechanical type, and is configured to forcibly discharge groundwater to the outside through the drainage pipe culvert (70) when the groundwater level is higher than a certain level.

[0067] The buoy (90) is made of a material that can rise or fall due to buoyancy and is installed to protrude from the surface of the ground so that it can be recognized from the outside, and is configured to activate the drainage device (80) when it rises above a certain level.

[0068] FIG. 7 is another example according to the present invention in an underground culvert system using an underground drainage / water supply non-powered automatic control device, wherein a groundwater inflow pipe (30) has a plurality of water holes (11) drilled on its circumference and its exposed end is connected to a drainage pipe culvert (70) connected to a drainage device (80) in the same way as the exposed end of the perforated pipe culvert (10) so as to be drained.

[0069] That is, when supplying or flowing from the water supply device (20), the perforated pipe culvert (10) and the groundwater inflow pipe (30) can be used equally or selectively.

[0070] Meanwhile, the water supply device (20) that supplies and blocks water flowing in from the outside to the perforated pipe culvert (10) is the same as the embodiment in FIGS. 1 to 3, so a detailed description will be omitted.

[0071] It is obvious to those skilled in the art that the present invention is not limited by the embodiments described above and the attached drawings, and that it can be modified and applied in various ways not exemplified within the scope of the technical concept of the present invention, as well as widely applied by substituting each component and changing to equivalent alternative embodiments.

[0072] Therefore, content related to modifying and applying the technical features of the present invention should be interpreted as being included within the technical concept and scope of the present invention. Explanation of the symbols
