Abstract
Description
Technology Field
[0001] The present invention relates to a grating installed at the inlet of a drainage channel, and in particular to a grating that prevents the inflow of foreign substances. Background Technology
[0002] A grating is a drainage cover installed at the entrance of a drain formed at the edge of a road or similar area. It serves as a passageway for rainwater and sewage (hereinafter referred to as "flow") to flow into the drain while filtering out foreign matter. Generally, gratings are installed as a single unit or in a continuous series of one or more.
[0003] Typically, gratings feature a structure in which flat iron, formed in a plank shape, is shaped into a rectangular form, and bearing bars and crossbars are arranged in a grid pattern within a perimeter frame. Specifically, bearing bars formed from plank-shaped flat iron are welded at predetermined intervals within the perimeter frame, and rod-shaped crossbars are welded at predetermined intervals in directions intersecting the bearing bars to form a grid structure, allowing flowing water to pass through while filtering out foreign substances to a certain extent.
[0004] Meanwhile, although the grating described above prevents foreign matter from entering the drainage channel by filtering out foreign matter through the bearing bars and crossbars, a problem arises in that foreign matter smaller than the holes formed in the grating passes through the grating and enters the drainage channel. In addition, relatively large foreign matter, such as fallen leaves, gets caught in the grating and accumulates at the entrance of the drainage channel, obstructing the flow of water into the drainage channel. Prior art literature
[0005] Republic of Korea Published Patent Application (A) No. 10-2022-0166919 (December 20, 2022) The problem to be solved
[0006] The purpose of the present invention is to propose a grating that enables smooth drainage by effectively filtering out foreign substances, thereby preventing them from entering the drainage channel. means of solving the problem
[0007] The present invention achieves the above objective by proposing a grating for preventing foreign matter inflow, which is formed by including a perimeter frame formed in a rectangular shape and installed at the entrance of a drainage channel, wherein walls are formed to protrude upward at predetermined intervals along the perimeter frame, thereby forming a passage between them, so that foreign matter gets caught and filtered on the walls, and flowing water passes through the passage to flow into the drainage channel. Effects of the invention
[0008] According to the present invention, a grating that prevents foreign substances from entering can be obtained, which effectively filters foreign substances from the flowing water flowing into the drainage channel and also prevents foreign substances from accumulating at the entrance of the drainage channel, thereby allowing the flowing water to flow smoothly into the drainage channel and be drained.

[0010] The present invention proposes a grating for preventing foreign matter inflow, which is formed by including a perimeter frame formed in a rectangular shape and installed at the entrance of a drainage channel, wherein walls are formed to protrude upward at predetermined intervals along the perimeter frame, thereby forming a passage between them, so that foreign matter gets caught and filtered on the walls, and flowing water can pass through the passage and flow into the drainage channel.
[0011] Hereinafter, the present invention will be described in detail with reference to the attached drawings and preferred embodiments.
[0012] FIG. 1 is an exemplary diagram of a foreign substance ingress prevention grating according to the present invention, FIG. 2 is an exploded view showing the configuration of a foreign substance ingress prevention grating according to the present invention, FIG. 3 is an exemplary diagram showing an enlarged view of a key part of a foreign substance ingress prevention grating according to the present invention, and FIG. 4 is an exemplary diagram showing the side shape of a filter frame according to the present invention.
[0013] Generally, a grating is installed at the entrance of a drainage channel and is formed to filter out foreign substances to some extent while preventing people or vehicles from falling in, and to allow water to flow into the drainage channel. The foreign substance inflow prevention grating according to the present invention performs the same or similar function. As illustrated, the foreign substance inflow prevention grating according to the present invention is formed by including a border frame (100) that forms a rectangular shape, and walls (240) are formed at predetermined intervals along the border frame (100).
[0014] The perimeter frame (100) can be formed from flat iron plates shaped like planks. The flat iron plates are butted together and welded to form a rectangular frame, thereby forming the perimeter frame (100).
[0015] The walls (240) may be formed to occupy a part or the entire area of the perimeter frame (100). The walls (240) formed in this manner are formed to protrude upward at predetermined intervals, thereby forming a passage (260) between the walls (240). As a result, a structure is formed in which the walls (240) and the passage (260) are formed alternately.
[0016] As described above, by forming a structure in which the walls (240) and passages (260) are formed alternately, during the process of water flowing into the drainage channel, the water flows into the drainage channel along the passages (260), and foreign substances are caught and filtered by the walls (240). As a result, the inflow of substances into the drainage channel is prevented.
[0017] Here, the wall (240) formed as described above may be formed in the shape of a flat plate. However, it is not limited thereto, and the shape may be formed differently as needed, such as in the shape of a rod.
[0018] Meanwhile, the wall (240) and passage (260) according to the present invention can be formed in the filter frame (200).
[0019] The strainer (200) is formed in the shape of a plank with a predetermined length, and a wall (240) is formed at a predetermined height with a predetermined spacing on the upper part of a base (220) formed at a predetermined height. At this time, the height of the base (220) is formed to a standard that does not exceed the height of the perimeter frame (100), and the wall (240) is formed to a height that can protrude above the perimeter frame (100).
[0020] As described above, the walls (240) are formed at predetermined intervals on the upper part of the base (220), thereby forming a structure in which the walls (240) and passages (260) are alternately formed in the filter frame (200). The filter frame (200) formed in this manner is fixed in contact with the rim frame (100), and the base (220) is fixed in contact with the rim frame (100) by means of bolts, etc. Accordingly, the walls (240) are formed in a state where they protrude above the rim frame (100).
[0021] Here, the foreign matter ingress prevention grating according to the present invention may be formed in a structure in which flat bar-shaped bearing bars (140) are welded at predetermined intervals inside the rim frame (100), and bar-shaped crossbars (120) are welded at predetermined intervals in a direction intersecting the bearing bars (140). In this configuration, the filter frame (200) is fixed in contact with the inner wall surface of the rim frame (100), and when the filter frame (200) is coupled to the rim frame (100), the crossbars (120) are fitted into the passage (260) and coupled. The base (220) is fixed by pushing the filter frame (200) from the bottom to the top of the rim frame (100) so that it comes into contact with the rim frame (100), and in the process, the crossbars (120) are fitted into the passage (260). This configuration can be achieved by aligning the position of the passage (260) in the filter (200) with the position where the crossbar (120) is formed, and depending on the position where the passage (260) is formed, the crossbar (120) may be fitted into each passage (260) or the crossbar (120) may be fitted into and combined with a part of the passage (260).
[0022] The filter frame (200) formed as described above can be cut and used along the point where the passage (260) is formed. By cutting the filter frame (200) along the point where the passage (260) is formed, a flat plate can be formed in which the base (220) and one wall (240) are connected in the vertical direction. By individually fixing this to the required point on the border frame (100), a protruding wall (240) can be formed on the border frame (100).
[0023] In the present invention as described above, the wall (240) may be formed from an elastic material such as rubber. The wall (240) is formed so that it can be elastically bent by an external force. Additionally, the wall (240) formed to have elasticity may be formed to become thinner toward the top. Accordingly, the wall (240) can be bent smoothly.
[0024] As described above, if the wall (240) is formed to be curved to some extent, in a situation where the amount of water flow increases rapidly, the wall (240) bends, allowing the water to easily flow over the wall (240) and smoothly flow into the drainage channel. Furthermore, if a pedestrian or vehicle steps on the wall (240) while moving, the wall (240) is pressed and folded, thereby preventing safety accidents and preventing damage to the vehicle.
[0025] The foreign matter inflow prevention grating according to the present invention, formed as described above, can effectively filter foreign matter from the flowing water flowing into the drainage channel through a structure in which walls (240) and passages (260) are alternately formed on the upper part of the perimeter frame (100). In particular, by filtering foreign matter to a significant degree before it reaches the upper surface of the grating, the accumulation of foreign matter on the upper surface of the grating can be minimized, thereby preventing foreign matter from accumulating at the entrance of the drainage channel and obstructing the flow of water.
