Description

[Technical Field]

[0001] The present invention relates to a non-point pollution reduction device for bridge drains, and more particularly to a non-point pollution reduction device for bridge drains that is installed on a bridge, filters non-point pollutants flowing into the bridge drains, and can monitor the amount of non-point pollutants filtered. [Background technology]

[0002] Generally, pollutant discharge sources can be divided into point sources, which have a clear and limited discharge point, such as domestic sewage, industrial wastewater, and livestock wastewater, and non-point sources, which have a wide discharge area, such as farmland, pastures, forests, construction sites, mines, landfills, roads, and industrial sites.

[0003] Point pollutants discharged from point sources are easy to collect because their outflow points are clear, and because they are relatively less affected by seasons, annual emissions can be predicted. Design and maintenance of treatment facilities such as sewer systems and treatment plants for wastewater treatment is easy, eliminating concerns about water pollution due to pollutant outflow. However, non-point pollutants discharged from non-point sources are difficult to predict because their sources are both man-made and natural, their emission points are unspecified and unclear, they are released over a wide area while being diluted and dispersed, and emissions fluctuate greatly due to natural factors such as rainfall. They are also difficult to collect and their treatment efficiency is inconsistent, making design and maintenance of treatment facilities difficult.

[0004] The most common method of filtering non-point pollutants on land is to use sewage treatment facilities or to create wetlands that take aesthetics and functionality into consideration.

[0005] This method requires a large site and cannot be used for general bridges. In addition, non-point pollutants at bridges have traditionally flowed directly into rivers through drainage pipes without being filtered, resulting in river pollution.

[0006] Therefore, in order to treat the initial non-point source of rainwater pollution from bridges, various methods are used, such as installing facilities such as storage, infiltration, and equipment, and creating vegetation, and the application method varies depending on the site conditions, regional conditions, and characteristics of the watershed.

[0007] However, conventional bridge drainage outlet non-point pollution filtration devices have the problem that, because the bridge drainage outlets are small, when the filtration device is installed, the entire drainage pipe easily becomes clogged, restricting the water flow cross section and making monitoring impossible.

[0008] In particular, small bridges are often not designed with linear collection pipes, and it is difficult to secure vertical space on the abutment side. Therefore, when maintaining non-point pollution filtration devices that are suspended from the bridge deck / pier, it is necessary to use a folding ladder, a vacuum suction cleaning vehicle, etc., which increases installation costs, maintenance costs, and labor costs.

[0009] Generally, bridge drainage outlets are of a straight-down type, and since there is no linear drainage pipe and there is a lack of installation space on the abutment and pier side, a detour channel is necessary to prevent damage caused by flooding and clogging of the bridge drainage outlet. Here, the legal installation standard for detour channels is that the bottom of the outlet must be installed above the flood level.

[0010] Existing drain insert types have small drain outlets, so when a filtration device is inserted, the entire drain pipe easily becomes clogged. Also, since the average diameter of drain outlets in rigid frame bridges and girder bridges is 150mm to 200mm, when the device is inserted inside, the water flow cross section is obstructed, the capacity of the facility for filtering pollutants is insufficient, and the accumulated pollutants frequently cause drain pipe clogging accidents and make monitoring impossible.

[0011] Additionally, in order to secure overflow space, it is necessary to design an expansion (structural modification) of the drainage outlet within the bridge deck of the new bridge, but this is practically impossible as it would require structural modifications to the bridge deck and structural considerations such as the installation of linear collection pipes.

[0012] In addition, it is necessary to comply with regulations requiring that the bottom ends of outlets such as abutments, piers, mounted types, and fill types be above the flood level, and it is difficult to ensure a step when installing at the end of the linear water collection pipe on the abutment side.In particular, small bridges are often not designed with linear water collection pipes, and it is difficult to ensure vertical space on the abutment side, so the bridge deck and pier hanging method can only be maintained when using a bending ladder, etc., which increases installation and maintenance costs.

[0013] In other words, dredging using a vacuum suction sweeper is required during maintenance, which causes problems with suction lift, requiring 3 million won / day for the suction dredging truck, 300,000 won / day for the backwashing water truck, and 300,000 won / day for the articulated ladder truck. Manual dredging requires frequent work using the articulated ladder, and excessive labor costs are incurred due to insufficient power to clean five locations per day.

[0039] FIG. 1 is a diagram showing a state in which a bridge drain outlet asymmetric pollution reduction device according to an embodiment of the present invention is installed on a bridge.

[0040] As shown in Fig. 1, the astigmatism pollution reduction device 100 for a bridge drainage outlet according to an embodiment of the present invention can be installed on the bridge deck, wall, guardrail, etc. of a bridge 10. In this case, the astigmatism pollution reduction device 100 for a bridge drainage outlet can be installed one-to-one in correspondence with the drainage outlet 20 of the bridge 10.

[0041] The length of the non-point pollution reduction device 100 for a bridge drainage outlet can be adjusted depending on the structure, volume, environment, etc. of the bridge 10 on which it is installed, and it can be installed in a custom-made manner on the bridge 10.

[0042] The non-point pollution reduction device 100 for a bridge outfall can filter non-point pollutants flowing into the outfall 20 of the bridge 10 and release them into a river below the bridge 10. As a result, the non-point pollution reduction device 100 for a bridge outfall according to this embodiment can be variably installed on the bridge 10 and can efficiently filter non-point pollutants flowing into the outfall 20 of the bridge 10.

[0043] Hereinafter, the astigmatism pollution reducing device 100 for a bridge drainage outlet according to this embodiment will be described in detail.

[0044] FIG. 2 is a perspective view showing an astigmatism pollution reduction device for a bridge drainage outlet according to an embodiment of the present invention, and FIG. 3 is a partial projection view showing an astigmatism pollution reduction device for a bridge drainage outlet according to an embodiment of the present invention.

[0045] Referring to FIGS. 2 and 3, the non-point pollution reducing device 100 for a bridge drainage outlet according to this embodiment may include a fixing plate 110, a filter body 120, a filter module 130, and a communication module 140.

[0046] The fixing plate 110 may be formed with a structure for installing and fixing the non-point pollution reduction device 100 for a bridge drainage outlet to the bridge 10. The fixing plate 110 may include a first length adjusting portion 111, a bridge fixing portion 112, and a second length adjusting portion 113.

[0047] 5, the first length adjusting unit 111 may be installed to be adjustable in length in the height direction of the bridge 10. The first length adjusting unit 111 may include a first support plate 1111, a first slide plate 1112, and a first length fixing member 1113.

[0048] The first support plate 1111 may be formed in a rectangular shape having a certain length. A first sliding plate 1112 may be slidably connected to the first support plate 1111. For example, the first support plate 1111 may include a rail (not shown) along which the first sliding plate 1112 can slide.

[0049] The first support plate 1111 may include a first fixing hole 11111 through which the first length fixing member 1113 may pass.

[0050] The first slide plate 1112 can be movably connected to the first support plate 1111. The first slide plate 1112 is approximately JPEG2025529062000002.jpg712 is formed in a character shape and can cover a part of the first support plate 1111. For example, a slot (not shown) is formed in the first sliding plate 1112 so that the first sliding plate 1112 can slide along the rail of the first support plate 1111.

[0051] The first slide plate 1112 slides from the first support plate 1111 to adjust the overall length of the first length adjuster 111 .

[0052] The first sliding plate 1112 may include a second fixing hole 11121 through which the first length fixing member 1113 may pass.

[0053] The first length fixing member 1113 can fix the first sliding plate 1112 to the first support plate 1111. After the length of the first length fixing member 1113 is adjusted while the first sliding plate 1112 slides from the first support plate 1111, the first length fixing member 1113 can be inserted and coupled through the first fixing hole 11111 of the first support plate 1111 and the second fixing hole 11121 of the first sliding plate 1112.

[0054] The first length fixing member 1113 can fix the first sliding plate 1112 to the first support plate 1111 by being inserted into the first fixing hole 11111 and the second fixing hole 11121 to prevent the first sliding plate 1112 from moving.

[0055] The first length adjusting part 111 may be connected to a bridge fixing part 112 and a second length adjusting part 113 .

[0056] The bridge fixing part 112 may be hingedly connected to the first length adjusting part 111. JPEG2025529062000003.jpg713 may be formed in a letter shape, and may be inserted into the bridge 10 after being bent from the first length-adjusting portion 111. For example, the bridge fixing portion 112 is installed so that its length can be adjusted in a direction perpendicular to the height direction of the bridge 10, and the length can be adjusted according to the width of the bridge deck, wall, guardrail, etc. of the bridge 10.

[0057] The second length adjustment part 113 may be coupled to the first length adjustment part 111. The second length adjustment part 113 may include a second support plate 1131, a second slide plate 1132, and a second length fixing member 1133.

[0058] The second support plate 1131 may be coupled to the first support plate 1111 so as to be perpendicular to the first support plate 1111. The second support plate 1131 may be formed in a rectangular shape having a certain length.

[0059] A second slide plate 1132 may be slidably connected to the second support plate 1131. For example, the second support plate 1131 may include a rail (not shown) along which the second slide plate 1132 can slide.

[0060] The second support plate 1131 may include a third fixing hole 11311 through which the second length fixing member 1133 may pass.

[0061] The second slide plate 1132 can be movably connected to the second support plate 1131. The second slide plate 1132 is approximately JPEG2025529062000004.jpg712 is formed in a character shape and can cover a part of the second support plate 1131. For example, a slot (not shown) is formed in the second sliding plate 1132 so that the second sliding plate 1132 can slide along the rail of the second support plate 1131.

[0062] The second slide plate 1132 slides from the second support plate 1131 to adjust the overall length of the second length adjuster 113 .

[0063] The second slide plate 1132 may include a fourth fixing hole 11321 through which the second length fixing member 1133 may pass.

[0064] The second length fixing member 1133 may fix the second sliding plate 1132 to the second support plate 1131. After the length of the second length fixing member 1133 is adjusted while the second sliding plate 1132 slides from the second support plate 1131, the second length fixing member 1133 may be inserted and coupled through the third fixing hole 11311 of the second support plate 1131 and the fourth fixing hole 11321 of the second sliding plate 1132.

[0065] The second length fixing member 1133 can fix the second sliding plate 1132 to the second support plate 1131 by being inserted into the third fixing hole 11311 and the fourth fixing hole 11321 to prevent the second sliding plate 1132 from moving.

[0066] The fixing plate 110 may further include a first hinge 114, a second hinge 115, a wind protection part 116, and a lifting support base 117.

[0067] The first hinge 114 can connect the first length-adjusting part 111 and the bridge-fixing part 112. Referring to Figures 6 and 7, the first hinge 114 can be used to rotate the first length-adjusting part 111 when the astigmatism pollution reduction device 100 for bridge drains is lifted from the bridge 10.

[0068] The first hinge 114 connects one end of the bridge fixing part 112 and one end of the first length adjusting part 111 and may be formed in a cantilever type so that one end of the first length adjusting part 111 rotates from the bridge fixing part 112.

[0069] In other words, the first hinge 114 in this embodiment becomes the center of rotation when the lifting lever 30 is inserted into the first length adjustment part 111 while the bridge fixing part 112 is fixed to the bridge 10, and the first length adjustment part 111 can be rotated from the bridge fixing part 112 using the lifting lever 30.

[0070] When the first length adjustment part 111 rotates around the first hinge 114 in this manner, the filter body 120 and the filter module 130 are pulled up toward the upper side of the bridge 10 as shown in FIG. 4, and workers can perform maintenance and repairs by replacing the filter bag (1321 in FIG. 9) inside the filter module 130.

[0071] The second hinge 115 may connect the second length adjustment unit 113 and the filtering body 120. Referring to FIG. 8, the second hinge 115 may have one end rotatably connected to the second length adjustment unit 113 and the other end rotatably connected to the filtering body 120.

[0072] The second hinge 115 allows the filtering body 120 to rotate from the second length adjustment part 113 when the astigmatic pollution reducing device 100 for bridge drainage outlets is pulled up from the bridge 10 .

[0073] When the non-point pollution reduction device 100 for bridge drains is pulled up from the bridge 10, the first length adjustment part 111 rotates from the bridge fixing part 112 around the first hinge 114, and the filter body 120 rotates from the second length adjustment part 113, and can move while maintaining the angle shown in the drawing.

[0074] If the filter body 120 does not rotate from the second length-adjusting part 113, that is, if the filter body 120 is fixed to the second length-adjusting part 113, when the first length-adjusting part 111 rotates from the bridge fixing part 112 around the first hinge 114, the filter body 120 rotates 180 degrees, and all of the non-point pollutants collected in the filter module 130 inside the filter body 120 flow into the river.

[0075] To prevent such a situation, the second hinge 115 of this embodiment can rotate the filter body 120 from the second length adjustment part 113, and continuously position the inlet of the filter body 120 in a direction facing the drain outlet 20 of the bridge 10.

[0076] The wind motion prevention part 116 can prevent the second hinge 115 from rotating due to wind. The wind motion prevention part 116 can hold the filter body 120 while being coupled to the second length adjustment part 113.

[0077] Referring to FIG. 8, the wind protection unit 116 may include a wind protection support plate 1161, a wind protection lock member 1162, a third hinge 1163, a spring lock member 1164, and a wind lock control cable 1165.

[0078] The wind-preventing support plate 1161 may be coupled to the second length adjusting portion 113. The wind-preventing support plate 1161 may be installed apart from the second hinge 115.

[0079] The wind-proof support plate 1161 may be connected to the wind-proof locking member 1162 by a third hinge 1163 .

[0080] The wind-preventing locking member 1162 may be connected to the wind-preventing support plate 1161 by a third hinge 1163. The wind-preventing locking member 1162 is formed in a substantially "J" shape and can grip the filter body 120 by forming a bend 11622 toward the filter body 120.

[0081] The wind-proof locking member 1162 may include a cable fixing hole 11621. A wind-lock control cable 1165 may be connected to the cable fixing hole 11621. The wind-proof locking member 1162 may grip the filtering body 120 and prevent the filtering body 120 from rotating from the second hinge 115, depending on whether or not the wind-lock control cable 1165 locks the spring locking member 1164. In some cases, the wind-proof locking member 1162 does not grip the filtering body 120.

[0082] In other words, under normal circumstances, the wind-motion prevention locking member 1162 grips the filter body 120 while the spring locking member 1164 is locked, and when the astigmatic pollution reduction device 100 for bridge drainage outlets is pulled by the wind-motion lock control cable 1165, the spring locking member 1164 is unlocked as the wind-motion prevention support plate 1161 rotates at the third hinge 1163, and the filter body 120 may not be gripped.

[0083] The third hinge 1163 can connect the wind protection locking member 1162 to the wind protection support plate 1161. The third hinge 1163 can rotate the wind protection locking member 1162 from the wind protection support plate 1161.

[0084] The spring lock member 1164 may have one end connected to the wind-proof support plate 1161 and the other end connected to the wind-proof lock member 1162. The spring lock member 1164 may be locked by an operator and unlocked by a wind-lock control cable 1165.

[0085] The wind lock control cable 1165 can be connected to the cable fixing hole 11621 of the wind protection lock member 1162. The wind lock control cable 1165 can be pulled by an operator, and when the wind lock control cable 1165 is pulled, the wind protection lock member 1162 can be rotated from the wind protection support plate 1161, and the spring lock member 1164 can be unlocked.

[0086] The lifting support stand 117 may be formed to protrude from a side of the first length adjustment unit 111. The lifting support stand 117 may connect a rope (not shown) to the lifting support stand 117 and assist in rotating the first length adjustment unit 111 when lifting the device 100 for reducing non-point pollution for a bridge drainage outlet.

[0087] That is, a rope may be connected to the auxiliary lifting table 117. The rope connected to the auxiliary lifting table 117 may be pulled by an operator to rotate the first length adjusting unit 111.

[0088] The filtering body 120 may be connected to the second length-adjusting part 113 so as to face the drainage outlet 20 of the bridge 10. The filtering body 120 may be rotated from the second length-adjusting part 113 while being connected to the second length-adjusting part 113 by the second hinge 115. At this time, the rotation of the filtering body 120 from the second length-adjusting part 113 may be restricted by the wind movement prevention part 116.

[0089] The filtering body 120 may include a plurality of river outlets 121, 122. The plurality of river outlets 121, 122 may be installed through the inside of the filtering body 120 at regular intervals.

[0090] The first river discharge port 121 is formed on the upper side of the filter body 120, and allows water that flows into the filter body 120 and overflows to the upper part to be discharged into the river.

[0091] The second river discharge port 122 is formed at the lower side of the filter body 120, and can discharge water that has flowed into the filter body 120 into the river.

[0092] In one embodiment, a filter (not shown) may be installed in each of the first river outlet 121 and the second river outlet 122. The filters installed in the first river outlet 121 and the second river outlet 122 may prevent foreign matter from being discharged into the river from the filter body 120.

[0093] A filtering module 130 may be installed inside the filtering body 120, and a communication module 140 may be installed outside the filtering body 120.

[0094] The filtration module 130 may be installed inside the filtration body 120. The filtration module 130 may filter non-point contaminants that have flowed into the filtration body 120. The filtration module 130 may include a collection unit 131, a filtering unit 132, and a weight sensing unit 133.

[0095] The collection unit 131 may have an open top and bottom. The collection unit 131 is formed in a shape in which the cross-sectional diameter gradually decreases from the top to the bottom, thereby capturing non-point contaminants flowing into the filter body 120.

[0096] The collection unit 131 may be connected to the filtering unit 132 by a weight sensing unit 133 .

[0097] The filtering unit 132 may be connected to the collecting unit 131 through a weight sensing unit 133. The filtering unit 132 may filter non-point contaminants collected by the collecting unit 131.
