Description

Technical Field

[0001] This invention relates to a garbage collector for drainage systems, and more specifically, to a garbage collector for drainage systems installed at the inlet of a drainage system that, when open, guides rainwater and other water flowing in through a grid to the drainage system below, and when closed, prevents other garbage falling from surrounding roads from entering the drainage system below, and can be manually removed after collection. Background Technology

[0002] Generally speaking, drainage channels formed along roadsides or in various places such as parks and playgrounds are equipped with drainage covers (garbage collectors for drainage channels) as one of the drainage facilities, so as to provide stress relative to the load applied from above, and to allow rainwater or sewage to drain smoothly while filtering out larger foreign objects.

[0003] A typical drain cover installed at the top of a drain channel typically has multiple flat iron or I-shaped load-bearing bars welded along its width between two side frames. At the top of these load-bearing bars, multiple crossbars or spiral-shaped crossbars are arranged in a crisscross pattern. This configuration allows for the smooth drainage of rainwater or sewage while filtering out larger debris at the top of the drain channel. (Korean Patent No. 10-913210, etc.)

[0004] However, the conventional drain cover of this technology is an open structure in which the drain below is connected to the surrounding space above. As a result, the odor generated in the lower part of the drain is directly released into the atmosphere above, causing a serious odor problem around the drain.

[0005] In addition, since the drainage system is connected to the atmosphere, small foreign objects such as cigarette butts or fallen leaves can enter, causing problems such as clutter or blockage.

[0006] To eliminate this problem, various types of sealed drain covers have been proposed. A brief examination of one example of such a conventional sealed drain cover is provided. This sealed drain cover is configured to normally seal the upper part of the drain, opening only during rainwater to allow for smooth drainage. Specifically, a downwardly sloping surface is formed on the upper part of the frame. Above this sloping surface, an opening / closing member is rotatably hinged via a rotating shaft, remaining sealed under normal conditions. The cover includes: a buoyancy cylinder disposed at the lower part of the opening / closing member; a buoyancy body within the buoyancy cylinder that rises and falls with the inflow of water; and a buoyancy device configured to open and close the opening / closing member by means of the buoyancy body.

[0007] Therefore, under normal circumstances, the opening and closing mechanism seals the upper part of the drainage channel, not only cutting off odors from the lower part of the drainage channel but also preventing small foreign objects such as cigarette butts or fallen leaves from entering the drainage channel. During rain or flooding, the buoyancy device opens the opening and closing mechanism due to the inflow of water, allowing for smooth drainage. This eliminates the problems inherent in conventional open-type drainage covers. (Korean Patent No. 10-1064257)

[0008] However, because the opening and closing components of this conventional drain cover are inclined, the height difference between the grid at the drain inlet and the lower end of the inclined surface is excessive. For example, garbage at the lower end cannot be sucked in by the suction force of road sweepers and other vehicles, but remains in place and then enters the drain with rainwater, resulting in problems such as drain blockage or eventual pollution of sewage treatment plants. Summary of the Invention

[0009] This invention was developed to solve this problem, and its purpose is to provide a garbage collector for drainage channels. The base plate of the main frame is a flat horizontal plate structure. The opening and closing plate installed in the through part of the base plate also has a horizontal plate structure. The horizontal plate structure has the same height all the way to the upper end of the drainage channel inlet, so that the fallen leaves or other garbage on the road accumulated on the base plate and the opening and closing plate can be fully sucked away by the suction force of road sweepers, etc.

[0010] Another objective is to provide a garbage collector for a drainage system, wherein the opening adjustment limiter has a thread formed on its outer peripheral surface, and the corresponding base plate is provided with a screw hole having a thread that engages with the thread of the opening adjustment limiter, so that the opening adjustment limiter can be raised and lowered, thereby smoothly adjusting the opening range of the opening and closing plate according to the water inflow.

[0011] Another objective is to provide a garbage collector for drainage channels, wherein the bearing shaft mounting hole is an elongated hole structure so that the position of the hinge shaft can be varied along the length direction of the opening and closing plate. A shaft support plate is provided on one side of the bottom surface of the opening and closing plate, and the shaft support plate has multiple shaft position changing holes. The multiple shaft position changing holes are used to allow the hinge shaft to pass through, so that the position of the hinge shaft can be changed along the length direction of the opening and closing plate. This allows the removal of a weight hammer that is independently mounted on the bottom surface of the opening and closing plate, or the application of the weight hammer according to the position movement of the hinge shaft.

[0012] The waste collector for a drainage ditch according to an embodiment of the present invention as described above includes: a main frame having a hooking portion for hooking onto a hooking rib at the drainage ditch inlet, and having a through portion extending vertically through one side; an opening / closing plate attached to the through portion of the main frame, selectively opening and closing the through portion according to the load of water flowing in through the drainage ditch inlet; and a hinge shaft located between the main frame and the opening / closing plate, allowing the opening / closing plate to rotate axially relative to the main frame.

[0013] In addition, in a waste collector for a drainage ditch according to an embodiment of the present invention, the main frame may include: a base plate having the through portion in the center; a straight wall plate standing upright from the periphery of the base plate; and a hanging portion extending outward from the upper end of the straight wall plate.

[0014] In addition, in a waste collector for a drainage ditch according to an embodiment of the present invention, the base plate can be a flat horizontal plate structure, and the opening and closing plate installed in the through part of the base plate can have a horizontal plate structure together with the base plate, and the horizontal plate structure has the same height all the way to the upper end of the drainage ditch inlet.

[0015] In addition, in a waste collector for a drainage channel according to an embodiment of the present invention, the hinge shaft can be eccentric to either side along the length direction of the opening and closing plate, so that the opening and closing plate portion located on the opposite side of the hinge shaft can be rotated downward by means of the water load applied to the opening and closing plate and the through portion can be opened.

[0016] In addition, in a waste collector for drainage channels according to an embodiment of the present invention, the main frame may also be equipped with an opening degree adjustment limiter, which prevents the opening degree adjustment limiter from opening further after the through part is opened due to the opening and closing plate.

[0017] In addition, in a waste collector for drainage channels according to an embodiment of the present invention, one side of the opening adjustment limiter can be connected to the side of the base plate in the width direction corresponding to the axial direction of the hinge axis, and the other side can be a straight rod structure that extends and is fixed along the side of the opening and closing plate.

[0018] In addition, in a waste collector for drainage channels according to an embodiment of the present invention, one side of the opening adjustment limiter can intersect the axial direction of the hinge shaft and be connected to the side of the base plate adjacent to the hinge shaft in the length direction, and the other side can be a bending rod structure that extends straight upward and then bends towards the opening and closing plate side.

[0019] In addition, in a waste collector for drainage channels according to an embodiment of the present invention, the opening adjustment limiter may have a thread formed on its outer peripheral surface, and the corresponding base plate is provided with a screw hole having a thread that engages with the thread of the opening adjustment limiter, so as to allow the opening adjustment limiter to move up and down.

[0020] In addition, in a waste collector for a drainage channel according to an embodiment of the present invention, the opening and closing plate may also be equipped with a weight hammer, which can be restored to its original state if the water load is removed after the weight hammer opens downward on the opposite side of the hinge axis due to water load.

[0021] In addition, in a waste collector for a drainage system according to an embodiment of the present invention, the weight hammer may be mounted on one side of the bottom surface of the opening and closing plate, which serves as the adjacent part of the hinge shaft.

[0022] In addition, in a waste collector for a drainage channel according to an embodiment of the present invention, the opening and closing plate may also be equipped with an anti-lift limiter, which is used to prevent the corresponding opening and closing plate portion from exceeding the through portion and lifting upward when it returns to its original state as the water load is removed.

[0023] In addition, in a waste collector for drainage channels according to an embodiment of the present invention, the anti-lift limiter can be a strip structure, with one side connected to the bottom surface of the corresponding restored opening and closing plate, and the other side extending to the bottom surface of the base plate that is aligned with and close to the restored opening and closing plate, so as to be attached to the bottom surface of the base plate.

[0024] In addition, in a waste collector for drainage channels according to an embodiment of the present invention, the base plate may also be equipped with bearings that extend downward from both sides in the width direction and have shaft mounting holes for mounting the hinge shaft in a shaft manner.

[0025] In addition, in a waste collector for drainage channels according to an embodiment of the present invention, the shaft mounting hole of the bearing can be an elongated hole structure so that the position of the hinge shaft can be variable along the length direction of the opening and closing plate.

[0026] In addition, in a waste collector for drainage channels according to an embodiment of the present invention, the opening and closing plate may also be equipped with a shaft support plate on one side of the bottom surface. The shaft support plate has a plurality of shaft position changing holes. The plurality of shaft position changing holes surround and support the hinge shaft in a state of passing through, and are continuously arranged along the length direction, so that the hinge shaft changes position along the length direction of the opening and closing plate.

[0027] In addition, in a waste collector for a drainage system according to an embodiment of the present invention, the shaft support plate may be equipped with a plurality of movable slits that connect the various shaft position change holes, and the hinge shaft may also be equipped with a movable piece on one side so that the hinge shaft can be moved along the movable slit from one side shaft position change hole to an adjacent shaft position change hole.

[0028] As described above, in a waste collector for drainage channels according to an embodiment of the present invention, the base plate of the main frame is a flat horizontal plate structure, and the opening and closing plate installed in the through part of the base plate also has a horizontal plate structure together with the base plate. The horizontal plate structure has the same height all the way to the upper end of the drainage channel inlet, thereby having a height that allows fallen leaves or other garbage on the road accumulated on the base plate and the opening and closing plate to be fully sucked away by the suction force of road sweepers, etc. As a result, garbage that is not sucked up and remains in place can be prevented from entering the drainage channel with rainwater and ultimately polluting the sewage treatment plant, etc., thus eliminating the need for pollutant removal operations at the sewage treatment plant, and achieving the effects of not only saving operating costs, but also preventing operator safety accidents caused by entering the sewage treatment plant.

[0029] In addition, the opening adjustment limiter has threads formed on its outer peripheral surface, and the corresponding base plate is equipped with screw holes with threads that engage with the threads of the opening adjustment limiter, so that the opening adjustment limiter can move up and down. This allows the opening range of the opening and closing plate to be smoothly adjusted according to the water inflow. Therefore, even during the rainy season when rainwater flows in rapidly, appropriate measures can be taken to guide the rainwater smoothly through the drainage channel, and the road flooding or pollution caused by rainwater backflow can be prevented in advance, thereby improving the reliability of the product.

[0030] Furthermore, the bearing's shaft mounting hole is an elongated structure, allowing the hinge shaft's position to be variable along the length of the opening / closing plate. A shaft support plate is provided on one side of the bottom surface of the opening / closing plate, and the shaft support plate has multiple shaft position changing holes. These holes allow the hinge shaft to pass through, changing its position along the length of the opening / closing plate. This allows the removal of a weight hammer independently mounted on the bottom surface of the opening / closing plate, or the application of different weights of weight depending on the hinge shaft's position. This not only saves costs by removing the weight hammer but also allows for the selective use of weight hammers of various weights, improving the compatibility of the opening / closing plate and ultimately enhancing product competitiveness.

[0035] Figure 5 As another embodiment of the present invention, a garbage collector for a drainage system is shown in a perspective view of a hinge axis position change structure. Detailed Implementation

[0036] Below, as Figures 1 to 3 As shown, a waste collector for drainage channels according to an embodiment of the present invention includes a main frame 10, an opening and closing plate 20, and a hinge shaft 30.

[0037] The main frame 10 is a quadrilateral frame structure, equipped with a hooking part 11 that is hooked to the hooking edge 5 of the drainage channel inlet 3, and has a through part 12 that runs vertically through one side.

[0038] More specifically, the main frame 10 includes: a base plate 13 having a quadrilateral through-hole 12 in the center; a plurality of straight wall plates 14 standing upright from the periphery of the base plate 13; and a hanging part 11 extending horizontally outward from the upper end of each of the straight wall plates 14.

[0039] The opening and closing plate 20 is a quadrilateral plate structure, which is installed in the through part 12 of the main frame 10. The through part 12 is selectively opened and closed according to the load of the water flowing in through the drainage inlet 3.

[0040] Furthermore, the base plate 13 is a flat horizontal plate structure, and the opening and closing plate 20 installed in the through part 12 of the base plate 13 is also a horizontal plate structure together with the base plate 13. The horizontal plate structure has the same height all the way to the upper end of the drainage channel inlet 3.

[0041] The height from the base plate 13 and the opening / closing plate 20 to the upper end of the drainage inlet 3 is preferably such that fallen leaves or other garbage on the road that accumulate on the base plate 13 and the opening / closing plate 20 can be fully sucked away by the suction force of a road sweeper or the like.

[0042] The hinge shaft 30 is a long cylindrical bar structure, located between the main frame 10 and the opening / closing plate 20, and functions to allow the opening / closing plate 20 to rotate axially relative to the main frame 10.

[0043] More specifically, the hinge shaft 30 is eccentric to one side along the length of the opening and closing plate 20, so that the portion of the opening and closing plate 20 located on the opposite side away from the hinge shaft 30 can open the through portion 12 while rotating axially downward due to the water load such as rainwater applied to the opening and closing plate 20.

[0044] Furthermore, the main frame 10 may be equipped with an opening degree adjustment limiter 40, which, when the through portion 12 is opened by the opening and closing plate 20, prevents the opening and closing plate 20 from opening to a predetermined opening degree and then stops opening further.

[0045] The opening adjustment limiter 40 is a straight rod structure, with one side connected to the upper side of the base plate 13 in the width direction corresponding to the axial direction of the hinge shaft 30, and the other side extending straight up to the upper side of the opening and closing plate 20 and fixed.

[0046] The opening degree adjustment limiter 40 is fixed in position, so the opening and closing plate 20 can only be opened and closed within a predetermined opening degree range.

[0047] On the other hand, another embodiment of the present invention, for example Figure 4 As shown, the opening adjustment limiter 50 can also be a bent rod structure, with one side intersecting the axial direction of the hinge shaft 30 and connected to the upper side of the base plate 13 adjacent to the hinge shaft 30 in the length direction, and the other side extending straight upward and then bending at a right angle towards the opening and closing plate 20.

[0048] Furthermore, the opening adjustment limiter 50 may also have a thread 51 formed on its outer peripheral surface, and the corresponding base plate 13 is equipped with a screw hole 13a having a thread 13b that engages with the thread 51 of the opening adjustment limiter 50, so that the opening adjustment limiter 50 can move up and down.

[0049] Because the opening degree adjustment limiter 50 is adjustable in height, the opening degree range of the opening and closing plate 20 can be smoothly adjusted according to the water inflow.

[0050] On the other hand, the opening and closing plate 20 is equipped with a square-shaped weight 60, which allows the hinge shaft 30 to return to its original state after the water load is removed if the opposite side is opened downward due to the water load.

[0051] The weight hammer 60 is provided on one side of the bottom surface of the opening and closing plate 20, which is adjacent to the hinge shaft 30.

[0052] Furthermore, the opening and closing plate 20 is equipped with an anti-lift limiter 70, which is used to prevent the corresponding opening and closing plate 20 portion from exceeding the through portion 12 and rising upward when it returns to its original state as the water load is released.

[0053] The anti-lift limiter 70 is a strip structure, with one side connected to the bottom surface of the corresponding opening and closing plate 20 of the restored part, and the other side extending to the bottom surface of the base plate 13, which is aligned with and close to the restored opening and closing plate 20 part, and is attached to the bottom surface of the base plate 13.

[0054] In addition, the base plate 13 is equipped with a long quadrilateral plate-shaped bearing 15, which extends downward from both sides in the width direction and has a circular hole-shaped shaft mounting hole 15a for the hinge shaft 30 to be mounted in a shaft manner.

[0055] The bearing 15, while supporting the hinge shaft 30, also guides the opening and closing plate 20 to rotate accurately in the axial direction without biasing to the side.

[0056] Undescribed reference numeral 16 represents a shaft support plate that surrounds the outer peripheral surface of the hinge shaft 30 and is mounted on the bottom surface of the opening / closing plate 20.

[0057] On the other hand, another embodiment of the present invention, for example Figure 5 As shown, the shaft mounting hole 81 of the bearing 80 can be an elongated hole structure so that the position of the hinge shaft 90 can be variable along the length direction of the opening and closing plate 20.

[0058] Furthermore, the opening and closing plate 20 may be equipped with a shaft support plate 100 on one side of the bottom surface. The shaft support plate 100 has a plurality of shaft position changing holes 101. The plurality of shaft position changing holes 101 surround and support the hinge shaft 90 in a state of passing through, while being continuously arranged along the length direction, so that the hinge shaft 90 can change position along the length direction of the opening and closing plate 20.

[0059] Furthermore, the shaft support plate 100 is equipped with a plurality of movable slits 102 that connect the various shaft position change holes 101, and the hinge shaft 90 is equipped with a movable piece 91 on one side so that the hinge shaft 90 can be moved along the movable slits 102 from one side of the shaft position change hole 101 to an adjacent shaft position change hole 101.

[0060] Therefore, the weight hammer (not shown) that is independently mounted on the bottom surface of the opening and closing plate 20 can be removed, or the weight of the weight hammer can be applied differently depending on the position of the hinge axis 90.

[0061] The undescribed reference numeral 92 represents a wing nut used to allow the hinge shaft 90 to be attached to the outer side of the bearing 80 to prevent it from detaching from the bearing 80.

[0062] The following examines an example of the use of a waste collector for drainage systems according to an embodiment of the present invention with this configuration.

[0063] First, the opening and closing plate 20 is connected to the through part 12 of the main frame 10 via the hinge shaft 30 to complete the assembly of the garbage collector.

[0064] After the main frame 10 is attached to the hook 5 of the drain inlet 3, the grid 7 is placed on the hook 11 to complete the installation of this garbage collector.

[0065] Under these conditions, after a predetermined time, fallen leaves and other garbage around the road fall through the grid 7 and accumulate on the bottom plate 13 and opening / closing plate 20 of the main frame 10 before entering the drainage channel.

[0066] Therefore, as the road sweeper passes over the grid 7, it sucks in and sweeps the garbage accumulated on the base plate 13 and the opening and closing plate 20 through the suction device.

[0067] Through this process, garbage on the road will not enter the drains but can be sucked in and collected at any time, thus preventing various existing problems (drain blockage or pollution of sewage treatment plants, etc.) from garbage entering the drains in advance.

[0068] Moreover, when there is rain, rainwater flows into the bottom plate 13 and the opening and closing plate 20 through the drainage inlet 3. At this time, if it is filled with rainwater to some extent, the opening and closing plate 20 rotates downward axially with the hinge axis 30 as a reference by the water load, and the through part 12 opens, allowing rainwater to flow into the drainage channel below.

[0069] At this time, due to the opening adjustment limiter 40, the opening and closing plate 20 can drain the rainwater only through the opening within the predetermined opening range.

[0070] On the other hand, during periods of heavy rainfall, such as the rainy season, an opening adjustment limiter 50 according to another embodiment of the present invention can be used to adjust to a larger opening.

[0071] Then, if the water load on the opening and closing plate 20 is released, the opening and closing plate 20, which was previously rotated downwards to open, returns to its original state due to the load of the weight hammer 60.

[0072] Among them, the anti-lift limiter 70, which is on the opposite side of the hinge axis 30, is attached to the bottom surface of the base plate 13 and can prevent the opening and closing plate 20 from being lifted to the top.

[0073] On the other hand, if the bearing 80, hinge shaft 90 and shaft support plate 100 of another embodiment of the present invention are applied, the opening and closing plate 20 does not need to be equipped with an additional weight hammer 60 on its bottom surface. The balance of the opening and closing plate 20 can be adjusted by changing the position of the hinge shaft 90 according to the shaft position change hole 101 so as to smoothly perform the opening and closing function.
