Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of urban drainage system design, and more specifically, to a sewage interception drainage ditch. Background Technology
[0002] Drainage ditches refer to ditches that divert water collected in side ditches, intercepting ditches, and low-lying areas near roadbeds, farmland, and residences to areas outside the roadbed, farmland, and residences. Drainage ditch design follows the layout and engineering standards of drainage systems, determining the depth and spacing of field drainage ditches, and analyzing and calculating the flow rate, water level, cross-sectional dimensions, and engineering quantities of drainage ditches and structures at all levels. The cross-section of drainage ditches can be rectangular, arched rectangular, trapezoidal, or horseshoe-shaped, among other forms. However, some pollutants can flow into drainage ditches, affecting the cleanliness of the water flow. Therefore, interceptor drainage ditches are needed to collect pollutants and are thus widely used.
[0003] Existing technology discloses a sewage interception drainage channel. However, when the water volume is small, the inlet opening is too large, resulting in a slow water flow within the channel. Sewage cannot be discharged promptly and remains in the channel for too long, causing odors or bacterial growth. During heavy rain, large amounts of rainwater accumulate on roads. If the inlet opening is too small, the drainage speed cannot keep up with the water accumulation, leading to road flooding and even urban flooding. Furthermore, the inability to promptly clean debris from the filter plates increases the risk of blockages due to debris buildup within the drainage channel. Utility Model Content
[0004] The purpose of this invention is to overcome the limitations of existing drainage ditches in adjusting their drainage rate according to changes in roadbed water accumulation, and to provide a sewage interception drainage ditch that can flexibly adjust its drainage rate according to actual drainage needs, thereby improving the effectiveness of the drainage ditch.
[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0006] A sewage interception and drainage channel is provided, including a channel body, an inlet cover plate on the top of the channel body, and a flow regulation mechanism inside the channel body. The flow regulation mechanism includes an adjusting float and a water passage plate. The water passage plate is provided with a plurality of water passage holes. The adjusting float is slidably connected to the channel body. The adjusting float is used to abut against the surface of the water passage plate and block part of the water passage holes.
[0007] During the operation of the above scheme, when there is little rainfall and road surface water, the adjusting float, under the action of gravity, presses against the water-passing plate inside the drainage channel box. The adjusting float blocks some of the water-passing holes on the plate, thus reducing the overall water-passing area. When water from the road surface flows into the drainage channel box through the inlet cover, the reduced water-passing area of the plate increases the flow velocity, allowing the water in the drainage channel box to flow out quickly. This effectively prevents water or sewage from remaining in the drainage channel box for too long, thus avoiding abnormal water accumulation. If the water doesn't smell or breed bacteria, when the weather changes badly and heavy rain causes excessive water accumulation on the road, a large amount of rainwater will flow into the drainage box. At this time, the small water-passing area on the water-passing plate is not enough to drain the water in time. The water gradually accumulates in the drainage ditch. The adjusting float will be buoyed and offset by gravity, and will float up and leave the water-passing plate. The water-passing hole that was originally blocked will naturally open. The water-passing area of the water-passing plate will increase, and the water in the drainage box can flow out faster, effectively preventing road water accumulation and even urban flooding.
[0008] Furthermore, it also includes a first sliding rod and a fixed plate. The two ends of the fixed plate are fixedly connected to the inner sidewall of the water channel box, and one end of the first sliding rod is connected to the fixed plate. The water passage plate is provided with a sliding hole, through which the first sliding rod passes. The adjusting float is slidably connected to the first sliding rod. The adjusting float is slidably connected to the water channel box through the fixed plate and the first sliding rod. The top of the water channel box needs to be filled with water. This arrangement can effectively avoid the reduction of the water inlet area at the top of the water channel box due to the connection between the adjusting float and the top of the water channel box, thereby reducing the drainage effect.
[0009] Furthermore, it also includes a sliding sleeve, one end of which is connected to the adjusting float. The sliding sleeve is slidably connected to the first sliding rod, and is located inside and slidably connected to the sliding hole. In order to ensure that the sliding action of the adjusting float is more stable and does not deflect when it floats up or sinks, the sliding sleeve is provided to increase the contact area between the adjusting float and the first sliding rod. The sliding sleeve passes through the sliding hole on the water-passing plate, and the sliding hole can also pass through water, thereby increasing the water-passing area when the adjusting float slides up.
[0010] Furthermore, the adjusting float is located on the side of the water-passing plate away from the fixed plate. When the adjusting float rises, its bottom surface moves away from the top surface of the water-passing plate. When the adjusting float descends, its bottom surface abuts against the top surface of the water-passing plate. The adjusting float is positioned on the side of the water-passing plate away from the fixed plate. This arrangement ensures that when there is excessive water accumulation, the adjusting float rises, increasing the water-passing area of the water-passing plate and thus increasing the drainage volume. If the adjusting float were positioned on the side of the water-passing plate closer to the fixed plate, when there is excessive water accumulation, the rising adjusting float would abut against the water-passing plate, blocking the water-passing holes and reducing the water-passing area, thus failing to achieve the effect of increasing the drainage volume.
[0011] Furthermore, the fixing plate is located below the water-passing plate, and a limiting part is provided at the end of the first slide rod away from the fixing plate. When the adjusting float rises to the limit position, the top surface of the adjusting float abuts against the bottom surface of the limiting part. The adjusting float cannot float excessively under the action of buoyancy and thus detach from the first slide rod. Therefore, the first slide rod needs to be provided with a limiting part to restrict the adjusting float.
[0012] Furthermore, a filtration mechanism is also provided at the bottom of the water channel box. The filtration mechanism includes a filter plate, a storage tank, a connecting line, and a float. The storage tank is fixedly connected to the outer wall of the water channel box. A first debris discharge trough is provided on the side of the water channel box near the storage tank. One end of the filter plate is slidably connected to the inner wall of the water channel box, and the other end is inserted into the first debris discharge trough. The float is located on the side of the filter plate away from the adjusting float block. The float is connected to the adjusting float block through the connecting line. The function of the filtration mechanism is to filter impurities and prevent the water channel box from being blocked by debris, thus preventing effective drainage. The float is connected to the adjusting float block through the connecting line. When the adjusting float block rises, the float will push the filter plate to slide upward synchronously. The debris on the filter plate can enter the storage tank through the debris discharge trough.
[0013] Furthermore, the width of the first waste removal trough is greater than the thickness of the filter plate; the width of the first waste removal trough should be set to be greater than the thickness of the filter plate and should be set to be larger so that the debris on the filter plate can easily enter the waste storage box through the waste removal trough.
[0014] Furthermore, it also includes a slider. A second sliding rod is also provided on the inner side wall of the water channel box. One end of the slider is slidably connected to the second sliding rod, and the other end is rotatably connected to the filter plate. When the slider slides to the lower limit position of the second sliding rod, the end of the filter plate near the slider is higher than the end near the first row of debris. The slider is designed so that the filter plate can slide up and down relative to the inner wall of the water channel box, and can also rotate relative to it. Driven by the float, the filter plate rotates through the slider, tilting and the tilt angle changes frequently. Under the action of the tilting force, the debris gradually slides into the storage box through the first row of debris. The more water enters the water channel box, the faster the float rises, the faster the tilt angle of the filter plate changes, and the faster the debris is discharged. The filter plate is tilted so that the end near the slider is higher than the end near the first row of debris, so that the debris can slide into the storage box.
[0015] Furthermore, a driving device is provided outside the water channel box. A third sliding rod and a push plate are provided inside the water channel box below the filter plate. The third sliding rod and the push plate are slidably connected. The two ends of the third sliding rod are fixedly connected to the inner wall of the water channel box. The driving device is connected to the push plate and drives the push plate to slide along the third sliding rod. The water channel box is also provided with a second row of debris troughs. The second row of debris troughs is located below the first row of debris troughs and connects the inner cavity of the water channel box with the inner cavity of the debris storage box. The filter plate can only filter larger debris. Smaller debris, such as sludge, cannot be filtered. These debris will accumulate in the water channel box for a long time and breed bacteria and produce odors. Therefore, a debris removal system with a driving device is required. The driving device drives the push plate to slide along the third sliding rod and pushes the small debris through the second row of debris troughs into the debris storage box.
[0016] Furthermore, the second debris discharge trough is located on one inner wall of the water channel box, and the projection of the push plate in its direction of movement is located in the second debris discharge trough; the push plate can directly drive the debris into the second debris discharge trough and allow the debris and sludge to enter the debris storage box.
[0017] Compared with the prior art, the beneficial effects of this utility model are:
[0018] 1. The drainage channel box is equipped with a flow regulation mechanism, which includes an adjusting float and a water-passing plate. The water-passing plate has several water-passing holes. The adjusting float is slidably connected to the drainage channel box and is used to abut against the surface of the water-passing plate and block some of the water-passing holes. When the rainfall is light and there is not much water on the road, some of the water-passing holes on the water-passing plate will be blocked by the adjusting float, reducing the water-passing area of the water-passing plate and increasing the flow rate of the water, so that the water can be discharged quickly and avoid the generation of odors or the growth of bacteria. When the water accumulates in the drainage channel box and there is too much water on the road due to heavy rain, the previously blocked water-passing holes will naturally open, increasing the water-passing area of the water-passing plate, so that the water in the drainage channel box can flow out faster, effectively preventing the water from accumulating on the road or even causing urban flooding.
[0019] 2. A filter mechanism is also installed at the bottom of the water channel box. The function of the filter mechanism is to filter impurities and effectively prevent blockage caused by the accumulation of debris in the water channel box. Attached Figure Description

[0028] Example 1
[0029] This embodiment is a first embodiment of a sewage interception drainage ditch, such as... Figures 1 to 3As shown, the device includes a water channel box 100, with an inlet cover 130 on the top of the water channel box 100. A flow regulating mechanism 200 is installed inside the water channel box 100. The flow regulating mechanism 200 includes an adjusting float 210 and a water-passing plate 220. The water-passing plate 220 is provided with a plurality of water-passing holes 221. The adjusting float 210 is slidably connected to the water channel box 100. The adjusting float 210 is used to abut against the surface of the water-passing plate 220 and block part of the water-passing holes 221.
[0030] Specifically, it also includes a first sliding rod 300 and a fixed plate 400. The two ends of the fixed plate 400 are fixedly connected to the inner sidewall of the water channel box 100, and one end of the first sliding rod 300 is connected to the fixed plate 400. The water passage plate 220 is provided with a sliding hole 222. The first sliding rod 300 passes through the sliding hole 222, and the adjusting float 210 is slidably connected to the first sliding rod 300. The adjusting float 210 is slidably connected to the water channel box 100 through the fixed plate 400 and the first sliding rod 300. The top of the water channel box 100 needs to be filled with water. This configuration can effectively prevent the water inlet area at the top of the water channel box 100 from being reduced due to the connection between the adjusting float 210 and the top of the water channel box 100, thereby reducing the drainage effect.
[0031] Specifically, it also includes a sliding sleeve 500. One end of the adjusting float 210 is connected to the sliding sleeve 500. The sliding sleeve 500 is slidably connected to the first sliding rod 300. The sliding sleeve 500 is located in the sliding hole 222 and is slidably connected to the sliding hole 222. In order to ensure that the sliding action of the adjusting float 210 is more stable and does not deflect when it floats or sinks, the sliding sleeve 500 is set to increase the contact area between the adjusting float 210 and the first sliding rod 300. The sliding sleeve 500 passes through the sliding hole 222 on the water-passing plate 220. The sliding hole 222 can also pass water. When the adjusting float 210 slides and floats, the water-passing area is increased.
[0032] Specifically, the adjusting float 210 is located on the side of the water-passing plate 220 away from the fixed plate 400. When the adjusting float 210 rises, its bottom surface moves away from the top surface of the water-passing plate 220. When the adjusting float 210 falls, its bottom surface abuts against the top surface of the water-passing plate 220. The adjusting float 210 is positioned on the side of the water-passing plate 220 away from the fixed plate 400. This arrangement ensures that when there is excessive water accumulation, the adjusting float 210 floats up, increasing the water-passing area of the water-passing plate 220 and increasing the drainage volume. If the adjusting float 210 were positioned on the side of the water-passing plate 220 closer to the fixed plate 400, when there is excessive water accumulation, the floating adjusting float 210 would abut against the water-passing plate 220, blocking the water-passing hole 221 and reducing the water-passing area, thus failing to achieve the effect of increasing the drainage volume.
[0033] Specifically, the fixed plate 400 is located below the water-passing plate 220. The end of the first slide bar 300 away from the fixed plate 400 is provided with a limiting part 310. When the adjusting float 210 rises to the limit position, the top surface of the adjusting float 210 abuts against the bottom surface of the limiting part 310. The adjusting float 210 cannot float excessively under the action of buoyancy and thus detach from the first slide bar 300. Therefore, the first slide bar 300 needs to be provided with a limiting part 310 to restrict the adjusting float 210.
[0034] The working principle of a sewage interception and drainage ditch in this embodiment is as follows:
[0035] Water from the road surface enters the drainage ditch box 100 through the inlet cover 130. When the rainfall is light and there is not much water on the road, the adjusting float 210 presses down on the water-passing plate 220 inside the drainage ditch box 100 under the action of gravity, thereby blocking some of the water-passing holes 221 set on the water-passing plate 220. The water-passing area of the water-passing plate 220 becomes smaller, and the flow rate of the water increases. When the weather changes severely and heavy rain causes excessive water accumulation on the road, a large amount of rainwater flows through the inlet cover 130 into the drainage ditch box 100. The water gradually accumulates in the drainage ditch, and the adjusting float 210 will be counteracted by buoyancy and float up away from the water-passing plate 220. The previously blocked water-passing holes 221 will naturally open, the water-passing area of the water-passing plate 220 will increase, and the water in the drainage ditch box 100 can flow out faster.
[0036] The beneficial effects of this embodiment are as follows: When the rainfall is light and there is not much water on the road, adjusting the float 210 can reduce the water-passing area of the water-passing plate 220, thereby increasing the flow rate and allowing the water to be discharged quickly, avoiding the generation of odors or the growth of bacteria; when heavy rain causes excessive water on the road, adjusting the float 210 can increase the water-passing area of the water-passing plate 220, allowing a large amount of water in the water channel box 100 to flow out quickly, effectively preventing water accumulation on the road or even causing urban flooding.
[0037] Example 2
[0038] This embodiment is a second embodiment of a sewage interception drainage ditch, such as... Figure 3 and 5As shown, the difference from Embodiment 1 is that a filter mechanism 600 is also provided at the bottom of the water channel tank 100. The filter mechanism 600 includes a filter plate 610, a storage tank 620, a connecting line 630, and a float 640. The storage tank 620 is fixedly connected to the outer wall of the water channel tank 100. A first row of debris troughs 110 is provided on the side of the water channel tank 100 near the storage tank 620. One end of the filter plate 610 is slidably connected to the inner wall of the water channel tank 100, and the other end is inserted into the first row of debris troughs 110. The float 640 is positioned... On the side of the filter plate 610 away from the adjusting float 210, the float 640 is connected to the adjusting float 210 via a connecting line 630. The function of the filter mechanism 600 is to filter impurities and prevent the water channel tank 100 from being blocked by debris, thus preventing effective drainage. The float 640 is connected to the adjusting float 210 via the connecting line 630. When the adjusting float 210 rises, the float 640 will push the filter plate 610 to slide upward synchronously. The debris on the filter plate 610 can enter the debris storage tank 620 through the debris discharge trough.
[0039] Specifically, the width of the first row of debris troughs 110 is greater than the thickness of the filter plate 610; the width of the first row of debris troughs 110 should be set to be greater than the thickness of the filter plate 610 and should be set to be larger so that the debris on the filter plate 610 can easily enter the debris storage box 620 through the debris discharge trough.
[0040] Specifically, it also includes a slider 710, and a second slide rod 700 is provided on the inner side wall of the water channel box 100. One end of the slider 710 is slidably connected to the second slide rod 700, and the other end is rotatably connected to the filter plate 610. When the slider 710 slides to the lower limit position of the second slide rod 700, the end of the filter plate 610 near the slider 710 is higher than the end near the first row of debris troughs 110. The arrangement of the slider 710 allows the filter plate 610 to slide up and down relative to the inner wall of the water channel box 100, and also to rotate relative to it, in the floating... Driven by the ball 640, the filter plate 610 rotates through the slider 710, tilting and the tilt angle changes frequently. Under the force of the tilting change, the debris gradually slides into the storage box 620 through the first row of debris troughs 110. The more water enters the water channel box 100, the faster the float 640 rises, the faster the tilt angle of the filter plate 610 changes, and the faster the debris is discharged. The filter plate 610 is tilted so that the end near the slider 710 is higher than the end near the first row of debris troughs 110, so that the debris can slide into the storage box 620.
[0041] The working principle of a sewage interception and drainage ditch in this embodiment is as follows:
[0042] When wastewater flows through the filter plate 610, debris is filtered by the filter plate 610. The filter plate 610 is tilted. When the float 640 does not move the filter plate 610, the filter plate 610 is at the lower limit position of the second slide bar 700. With the filter plate 610 tilted, the debris slides down through the first row of debris troughs 110 into the debris storage box 620 by gravity. When there is too much water, the debris on the filter plate 610 will also increase. At this time, the adjusting float 210 rises and drives the float 640 to rise synchronously through the connecting line 630. The float 640 drives the filter plate 610 to slide upward on the second slide bar 700 and rotate at the same time, shaking the debris on the filter plate 610, thereby accelerating the sliding of the debris into the debris storage box 620.
[0043] The beneficial effects of this embodiment are: the filter plate 610 and the impurity removal box can effectively filter the sewage and impurities in the water, and avoid blockage caused by the accumulation of impurities in the water channel box 100, thus reducing the drainage effect.
[0044] Example 3
[0045] This embodiment is a third embodiment of a sewage interception drainage ditch, such as... Figure 3 and 4 As shown, the difference from Embodiment 2 is that a drive device 140 is provided outside the water channel box 100. In this embodiment, the drive device 140 is a linear motor, but it can also be a cylinder or a slide module. A third slide rod 800 and a push plate 150 are provided in the inner cavity of the water channel box 100 below the filter plate 610. The third slide rod 800 and the push plate 150 are slidably connected, and both ends of the third slide rod 800 are fixedly connected to the inner wall of the water channel box 100. The drive device 140 is connected to the push plate 150 and drives the push plate 150 to slide along the third slide rod 800. The water channel box 100 also has... A second row of debris troughs 120 is provided. The second row of debris troughs 120 is located below the first row of debris troughs 110 and connects the inner cavity of the water channel box 100 with the inner cavity of the storage box 620. The filter plate 610 can only filter larger debris. Smaller debris, such as sludge, cannot be filtered. If these debris accumulate in the water channel box 100 for a long time, bacteria will grow and produce odors. Therefore, a debris removal system with a drive device 140 is required. The drive device 140 drives the push plate 150 to slide along the third slide bar 800 to push small debris through the second row of debris troughs 120 into the storage box 620.
[0046] Specifically, the second row of debris troughs 120 is located on one side of the inner wall of the water channel box 100, and the projection of the push plate 150 in its direction of movement is located in the second row of debris troughs 120; the push plate 150 can directly drive debris into the second row of debris troughs 120 and allow the debris and sludge to enter the debris storage box 620.
[0047] The working principle of a sewage interception and drainage ditch in this embodiment is as follows:
[0048] Impurities that cannot be filtered by the filter plate 610 settle at the bottom of the water channel box 100. The drive device 140 is activated, and the drive device 140 drives the push plate 150 to move along the third slide bar 800, thereby pushing and scraping the impurities at the bottom of the water channel box 100 into the storage box 620 through the second row of impurity troughs 120, where they are finally processed uniformly.
[0049] The beneficial effects of this embodiment are: the arrangement of the drive device 140 and the push plate 150 can effectively remove small debris such as sludge deposited at the bottom of the water channel tank 100, effectively preventing the growth of bacteria and the generation of odors.
[0050] In the specific implementation of the above embodiments, the technical features can be combined in any non-contradictory way. For the sake of brevity, not all possible combinations of the above technical features are described. However, as long as the combination of these technical features is not contradictory, it should be considered to be within the scope of this specification.
[0051] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
