Description

Technical Field

[0001] This application relates to the technical field of drainage ditches, and in particular to a self-regulating water circulation drainage ditch. Background Technology

[0002] Drainage ditches are an important part of daily life and flood control. All the water on the ground is drained into nearby rivers, lakes and seas through drainage ditches, thus ensuring people's normal life and safety of life and property.

[0003] Because drainage ditches are relatively long, impurities in the accumulated water tend to accumulate and remain in the ditches during operation, reducing their drainage capacity. Current technologies typically address this by installing filtration tanks. These tanks are connected to the drainage ditches via multiple water pipes, allowing for sedimentation and filtration before water recycling. By guiding water and impurities to the filtration tanks in multiple stages for sedimentation, the probability of impurities settling in the drainage ditches is reduced. The filtration tanks also allow for water recycling. However, in the initial stages, the rainwater flow is low and contains many impurities. The low flow rate leads to a significant accumulation of impurities in the drainage ditches. In the later stages, the rainwater flow is high but contains fewer impurities, resulting in less impurities entering the filtration tanks. Furthermore, the accumulation of impurities can cause blockages in the water pipes due to water impact, further reducing the drainage capacity of the drainage ditches. Summary of the Invention

[0004] To improve the drainage function of drainage ditches, this application provides a self-regulating water circulation drainage ditch.

[0005] This application provides a self-regulating water circulation drainage ditch, which adopts the following technical solution:

[0006] A self-regulating water circulation drainage ditch includes a drainage ditch body, on which multiple filtration mechanisms for filtering impurities and communicating with a filtration tank are provided. Each filtration mechanism includes:

[0007] A frame, which is mounted on the drainage ditch body and forms a drainage space with the drainage ditch body located below the frame;

[0008] A filter bag is detachably mounted on a frame via a connecting mechanism. The drainage space is used for water to pass through and for the filter bag to filter impurities. The filter bag has multiple filter holes for filtering impurities in the water.

[0009] A guide plate is rotatably mounted at the bottom of the frame via a pivot and located on the side of the frame closer to the water inflow. It is positioned on the drainage ditch body under the action of gravity. The guide plate is used to guide water to the filter bag for filtration.

[0010] A water guide pipe is installed on the body of the drainage ditch and is used to connect the body of the drainage ditch and the filter tank.

[0011] An adjustment component is mounted on the frame and connected to the guide plate, which is used to drive the guide plate to rotate. After the guide plate rotates, a flow space communicating with the drainage space is formed between the guide plate and the drainage ditch body located below the guide plate. The adjustment component adjusts the size of the flow space according to the water level.

[0012] By adopting the above technical solution, the initial rainwater enters the main body of the drainage ditch. At this time, the rainfall is small and there are many impurities. The mixture of water and impurities enters the filter bag for filtration under the action of the guide plate. The impurities remain in the filter bag, while the filtered water flows into the next section of the drainage ditch through the drainage space. Therefore, the water continues to flow to the next filtration mechanism for further filtration, or some water enters the filtration pool through the water guide pipe for recycling. When the filter bag is full, it is disassembled, cleaned, and replaced. Therefore, filtration is carried out section by section in the drainage ditch, which reduces the adverse effects of impurity sedimentation on the drainage of the drainage ditch. It also reduces the probability of impurities remaining in the filtration pool and being difficult to clean, thereby further improving the drainage function of the drainage ditch.

[0013] During the later stages of the rainy season, the rainfall is heavy and there are fewer impurities, causing the water level in the drainage ditch to rise. When the water level in the drainage ditch exceeds a designated height, the regulating component is activated, causing the guide plate to rotate. This creates a flow space between the guide plate and the main body of the drainage ditch located below the guide plate, allowing some water to enter the drainage space without passing through the filter bag. After the water impacts the filter bag, it is discharged into the filtration tank through the water guide pipe. The filter bag also blocks the water, allowing more water to enter the filtration tank through the water guide pipe, while some water enters the next section of the drainage ditch through the drainage space. When the water level drops, the guide plate rotates back and blocks the drainage space, allowing more impurities to be filtered through the filter bag.

[0014] By adjusting the components and the guide plate, the system filters impurities in the water when the water volume is low and there are many impurities. When the water volume is high and there are few impurities, the adjustment components are activated to rotate the adjustment plate, thereby reducing the obstruction effect on the water. This achieves both the functions of impurity filtration and increased drainage rate. The system can automatically adjust according to the water level and circulate the water through the filter tank, thereby improving the drainage function of the drainage ditch.

[0015] After filtering for a period of time, the filter bag will retain a lot of impurities. Under the action of gravity, the impurities pull the filter bag to lie flat on the body of the drainage ditch and in the drainage space, so that the filter bag can hold more impurities. Moreover, the impurities pull the filter bag to tighten, which increases the rate at which water passes through the filter bag. At the same time, the subsequent flowing water will also impact the impurities, causing more impurities to fall downwards and accumulate, thereby reducing the obstruction effect of impurities on the subsequent water when passing through the filter holes, thus improving the drainage function of the drainage ditch.

[0016] As the amount of impurities increases, the water flow rate decreases, which in turn causes the water level in the drainage ditch to rise. This rise in water level can also adjust the position of the guide plate through the adjustment components, thereby further reducing the probability of the filter bag becoming clogged and blocking the flow of rainwater, thus improving the drainage function of the drainage ditch.

[0017] Optionally, the guide plate has guide holes, and the adjustment component includes:

[0018] A buoyancy bar, which is slidably mounted on the frame and extends to the top of the drainage space;

[0019] A buoyancy plate, which is disposed on the top of a buoyancy rod and moves up and down under the action of water buoyancy;

[0020] An adjusting rod is provided on the bottom end of the buoyancy rod and slidably mounted on the guide hole, which drives the buoyancy plate to rotate after the buoyancy rod moves.

[0021] By adopting the above technical solution, when the water level is low, the guide plate does not contact the buoyancy plate. Under the weight of itself and the adjustment components, the guide plate is placed on the drainage ditch body to block the drainage space. When the water level rises, the buoyancy plate floats on the water surface. Therefore, the buoyancy plate moves upward, causing the buoyancy rod and the adjustment rod to move upward. The upward movement of the adjustment rod causes the guide plate to move away from the drainage ditch body, so that the guide plate and the drainage ditch body located below the guide plate create a flow space for water to pass through. This allows the size of the flow space to be adjusted by the water level, thereby improving the drainage function of the drainage ditch.

[0022] Optionally, the connecting mechanism includes:

[0023] A connecting plate is inserted into the bottom of the frame along the length of the drainage ditch body and has a connecting hole for the filter bag to pass through.

[0024] Positioning teeth, which are disposed on the connecting plate and pass through the filter holes and are used to position the filter bag;

[0025] The positioning plate is rotatably mounted on the connecting plate and engages with the positioning teeth, abutting against the filter bag for positioning.

[0026] By adopting the above technical solution, the connecting plate is pulled off, and then the connecting plate containing the new filter bag is inserted and installed onto the frame. The positioning plate is then rotated away from the filter bag, allowing the filter bag to be removed for cleaning. The new filter bag is then placed onto multiple positioning teeth, allowing the teeth to pass through the filter holes. The positioning plate is then rotated to engage with the teeth, pressing against the filter bag for positioning. The connecting plate is then inserted and installed onto the bottom of the frame. This process allows for the cleaning and replacement of the filter bag, which is then stored for later use. Simultaneously, the positioning teeth passing through the filter holes improve the stability of the filter bag, enhance its filtration efficiency, and improve the drainage function of the drainage ditch.

[0027] Optionally, the connecting plate is provided with a fixed plate and a sliding plate is slidably provided. The fixed plate and the sliding plate are respectively located on both sides of the connecting hole and are both provided with positioning teeth. There are two positioning plates, which are rotatably connected to the fixed plate and the sliding plate respectively. In the initial state, the sliding plate causes the filter bag opening to be open. After the sliding plate approaches the fixed plate, the two cooperate to clamp the filter bag opening and cause the filter bag opening to be closed. The connecting plate is provided with a moving component that drives the sliding plate to approach or move away from the fixed plate.

[0028] By adopting the above technical solution, when disassembling the connecting plate, the moving component is activated to move the fixed plate closer to the sliding plate, so that the fixed plate and the sliding plate cooperate to clamp the filter bag, thereby sealing the filter bag opening. Then, the connecting plate and the filter bag are moved to the cleaning area, and then the moving component is activated to move the fixed plate away from the sliding plate, and then the filter bag can be removed. This reduces the probability of impurities falling out of the filter bag during the movement and improves the convenience of cleaning.

[0029] Optionally, the moving component includes:

[0030] A movable rod, which is mounted on a sliding plate and slides through a connecting plate;

[0031] A push spring is provided, with both ends of the push spring sleeved on the moving rod and connected to the connecting plate and the sliding plate respectively, and is always in a compressed state. The sliding plate, under the action of the push spring, cooperates with the fixed plate to clamp the filter bag and close the bag opening of the filter bag.

[0032] The positioning block is vertically slidably mounted on the connecting plate and is inserted into the moving rod under the action of gravity for positioning and maintaining the initial state of the sliding plate.

[0033] By adopting the above technical solution, the positioning block is pushed upward and away from the moving rod. Therefore, the sliding plate and the moving rod approach the fixed plate under the action of the pushing spring, so that the sliding plate and the fixed plate cooperate to clamp the bag opening of the filter bag, thereby closing the bag opening of the filter bag; the moving rod is pulled to move the sliding plate away from the fixed plate, and the positioning block is inserted and installed on the moving rod under the action of gravity for positioning. At this time, the bag opening of the filter bag is opened.

[0034] Optionally, an overflow hole is provided on the frame above the filter bag, and a guide assembly is provided on the frame, the guide assembly including:

[0035] A guide plate, the bottom of which is rotatably mounted on the frame and located on both sides of the frame, respectively;

[0036] A torsion spring is provided on the frame and connected to the bottom of the guide plate, so that the guide plate presses against the frame and blocks the overflow hole, allowing water to flow into the filter bag for filtration.

[0037] By adopting the above technical solution, when the water level is low, the impact force of the water on the guide plate is less than the torsion force of the torsion spring. Therefore, the guide plate blocks the water and directs it downward into the filter bag for filtration. When the water level is high and the impact force on the guide plate is greater than the torsion force of the torsion spring, the water pushes the guide plate to rotate, creating a gap between the guide plate and the overflow hole. The water overflows through the gap into the next section of the drainage ditch, reducing the probability of water overflowing outward from the drainage ditch. After the water impact force decreases, the guide plate rotates and presses against the frame under the action of the torsion spring, and then continues to guide the water, thereby further improving the drainage function of the drainage ditch.

[0038] Optionally, a blocking assembly is disposed on the frame, the blocking assembly comprising:

[0039] A baffle plate is rotatably mounted on the bottom of the frame and located on both sides of the frame along with the guide plate. The baffle plate presses against the frame under gravity and is tilted downwards towards the side away from the drainage space. It forms a water passage space with the drainage ditch body located below the baffle plate for filtered water to pass through. The baffle plate is positioned by pressing against the connecting plate.

[0040] A locking element is provided on the frame and is used to lock the baffle plate when replacing the filter bag.

[0041] By adopting the above technical solution, when the water volume is small and the impact on the baffle plate is not large, the baffle plate blocks the water, allowing some water to enter the filter tank through the water guide pipe and some water to enter the next section of the drainage ditch through the water passage space. When the water flow increases and the impact on the baffle plate becomes larger, the baffle plate moves away and the water passage space is increased, allowing the water to move quickly to the next section of the drainage ditch. When the water volume decreases, the baffle plate rotates under the action of gravity, thereby improving the drainage function of the drainage ditch. Moreover, the probability of the baffle plate pressing against the connecting plate to prevent the connecting plate from moving and causing the filter bag to move is improved, thus improving the filtration effect.

[0042] The connecting plate is located at the bottom of the frame and within the drainage space. Therefore, when the connecting plate needs to be disassembled, rotate the baffle plate to the top of the connecting plate, and then lock the position of the baffle plate with the locking mechanism. After the connecting plate is disassembled, the locking mechanism is released, and the baffle plate rotates and presses against the frame under the action of gravity for positioning, which improves the convenience of cleaning the filter bag.

[0043] Optionally, the locking element is a locking screw, which is threaded onto the frame and abuts against the blocking plate for positioning.

[0044] Optionally, the blocking plate and the guide plate are spaced apart vertically and each has a magnet block on the side wall away from the frame that can be attracted together. After the blocking plate and the guide plate approach each other and abut together, the two magnet blocks are attracted together and used to position the blocking plate and the guide plate.

[0045] By adopting the above technical solution, when the water volume in the drainage ditch is large, the water impacts the guide plate and the baffle plate, causing them to rotate away from the frame. As a result, the guide plate and the baffle plate approach each other until they come into contact. At this point, the two magnets are attracted together for positioning, thus keeping the guide plate and the baffle plate at their maximum rotation angle. This maximizes the space for water to pass through, improving the drainage function of the drainage ditch. Simultaneously, when the water flow decreases, the baffle plate rotates upward under gravity, while the guide plate rotates upward under the action of the torsion spring, causing the baffle plate and the guide plate to return to their original positions, thereby improving the drainage function of the drainage ditch.

[0046] In summary, this application includes at least one of the following beneficial technical effects:

[0047] By adjusting the components and guide plates, the system filters impurities in the water when the water volume is low and there are many impurities. When the water volume is high and there are few impurities, the adjustment components are activated to rotate the adjustment plate, thereby reducing the obstruction effect on the water. This achieves both the functions of impurity filtration and increased drainage rate. The system can automatically adjust according to the water level and also circulate the water through the filter tank, thereby improving the drainage function of the drainage ditch.

[0054] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0055] This application discloses a self-regulating water circulation drainage ditch.

[0056] Reference Figure 1 The self-regulating water circulation drainage ditch includes a drainage ditch body 1. Multiple filter mechanisms 2 are arranged along the length of the drainage ditch body 1. The filter mechanisms 2 are used to filter impurities in the drainage ditch body 1 and are used to connect with a filter pool. The filter pool is a water pool for sedimentation and filtration of water. The water in the filter pool after sedimentation is used for watering flowers and other water uses, thereby realizing the recycling of water resources.

[0057] Reference Figure 1 and Figure 2The filtration mechanism 2 includes a frame 21 and a filter bag 22. The drainage ditch body 1 has a rectangular cross-section. The frame 21 is fixedly installed on the inner side wall of the drainage ditch body 1 and has a vertical plate-like structure. An overflow hole 11 is provided on the frame 21, which passes through the two side walls perpendicular to the length direction of the drainage ditch body 1. A water passage groove 12 is provided on the bottom wall of the overflow hole 11 and passes through the side wall of the frame 21 near the water inflow side. At the same time, a long strip-shaped water passage hole 13 is provided on the bottom wall of the water passage groove 12, and the length direction of the water passage hole 13 is parallel to the length direction of the frame 21 and perpendicular to the length of the drainage ditch body 1. A drainage space 16 is formed between the bottom of the frame 21 and the drainage ditch body 1 located below the frame 21. A horizontal rotating shaft 14 is fixedly installed on the side wall of the frame 21 near the water inflow side and below the water passage groove 12.

[0058] Reference Figure 2 and Figure 3 On the lower surface of the frame 21, at both ends of the water passage hole 13, there are fixed snap-fit ​​blocks 15. Each snap-fit ​​block 15 has a snap-fit ​​groove 18 on the end away from the rotating shaft 14. The two snap-fit ​​grooves 18 pass through the side wall of the opposite side of the two snap-fit ​​blocks 15. The filter bag 22 is detachably installed on the two snap-fit ​​blocks 15 through the connecting mechanism 4. The filter bag 22 is a mesh structure made of soft plastic. Multiple filter holes are evenly opened on the filter bag 22.

[0059] Reference Figure 2 , Figure 3 and Figure 4 The connecting mechanism 4 includes a connecting plate 41, positioning teeth 42, and positioning plate 43. The connecting plate 41 is snapped onto two snap-fit ​​grooves 18 and abuts against the bottom of the snap-fit ​​grooves 18 for positioning. A connecting hole 44 is provided on the upper surface of the connecting plate 41, which passes through the upper and lower surfaces of the connecting plate 41. The projections of the connecting hole 44 and the water passage hole 13 in the vertical direction coincide. Connecting grooves 45 communicating with the upper surface of the connecting plate 41 are provided on the opposite side walls of the connecting hole 44. Two positioning teeth 42 and two positioning plates 43 are provided and located on the two connecting grooves 45. A fixing plate 46 is fixedly installed in one connecting groove 45, while a sliding plate 47 is horizontally slidably installed in the other connecting groove 45. The sliding direction of the sliding plate 47 is along the direction of approaching or moving away from the fixing plate 46, while the fixing plate 46 is located on the side of the sliding plate 47 closer to the rotating shaft 14.

[0060] Reference Figure 3 and Figure 4Positioning teeth 42 are fixedly installed on the upper surfaces of the fixed plate 46 and the sliding plate 47, and multiple positioning teeth 42 are spaced apart along the length of the connecting hole 44 on both the fixed plate 46 and the sliding plate 47. The positioning teeth 42 are vertical and elastic. The opening of the filter bag 22 passes through the connecting hole 44 from below and moves to the fixed plate 46 and the sliding plate 47. Then, the positioning teeth 42 on the fixed plate 46 and the sliding plate 47 pass through the filter holes on the filter bag 22.

[0061] Reference Figure 3 and Figure 4 One of the positioning plates 43 is rotatably mounted on the upper surface of the fixed plate 46, and the other positioning plate 43 is rotatably mounted on the upper surface of the sliding plate 47. Each positioning plate 43 has multiple positioning grooves that engage with the positioning teeth 42. Rotating the positioning plate 43 closer to the positioning teeth 42 causes the positioning teeth 42 to engage with the multiple positioning grooves, and the positioning plate 43 presses against the filter bag 22 for positioning, thereby fixing the opening of the filter bag 22.

[0062] Reference Figure 2 , Figure 3 and Figure 4 The filter bag 22 is placed in the drainage space 16, and the connecting plate 41 is snapped onto the snap-fit ​​groove 18. The bottom of the frame 21 abuts against the upper surface of the connecting plate 41 for positioning, thereby preventing the positioning plate 43 from rotating and reducing the probability of the positioning plate 43 disengaging from the positioning teeth 42, thus improving the stability of the filter bag 22 during filtration. In the initial state, the sliding plate 47 is completely located in the connecting groove 45, so that the mouth of the filter bag 22 is open. Water and impurities enter the filter bag 22 for filtration. The impurities fall downwards under the action of gravity, and the downward fall of the impurities will pull the filter bag 22 to tighten. As the amount of impurities increases, the impurities are spread flat in the drainage ditch body 1 through the filter bag 22. At the same time, the subsequent water impacts the tightened filter bag 22, causing the impurities adhering to the filter bag 22 to fall off and accumulate, thereby accelerating the rate at which water passes through the filter bag 22.

[0063] Reference Figure 3 and Figure 4 The connecting plate 41 is provided with a moving component 5 that is connected to the sliding plate 47 and drives the sliding plate 47 to move. When the moving component 5 is activated, it drives the sliding plate 47 to move. The sliding plate 47 moves out of the connecting groove 45 and closes to the fixed plate 46, so that the fixed plate 46 and the sliding plate 47 cooperate to clamp the opening of the filter bag 22, thereby closing the opening of the filter bag 22 and reducing the probability of impurities falling out of the filter bag 22.

[0064] Reference Figure 3 and Figure 4The moving component 5 includes a moving rod 51, a pushing spring 52, and a positioning block 53. One end of the moving rod 51 is fixedly installed on the side wall of the sliding plate 47 away from the fixed plate 46, and the moving rod 51 slides along the moving direction of the sliding plate 47 and passes through the connecting plate 41. At the same time, the moving rod 51 extends out of the side wall of the connecting plate 41 away from the fixed plate 46. A vertical moving groove 48 is provided on the connecting plate 41 at the point where the moving rod 51 extends out of the connecting plate 41, and the moving rod 51 is located in the moving groove 48.

[0065] Reference Figure 3 and Figure 4 The push spring 52 is sleeved on the moving rod 51, and both ends of the push spring 52 press against the side walls of the sliding plate 47 and the connecting groove 45. At the same time, the push spring 52 pushes the sliding plate 47 to keep it close to the fixed plate 46, so that the push spring 52 is always in a compressed state. The positioning block 53 is vertically slidably installed on the inner side wall of the moving groove 48 and located above the moving rod 51. At the same time, the positioning block 53 is inserted into the moving rod 51 for positioning under the action of gravity. At this time, the sliding plate 47 is completely located in the connecting groove. Within 45, the filter bag 22 is in an open state; the positioning block 53 is pushed upward and disengaged from the moving rod 51, and the sliding plate 47 approaches the fixed plate 46 under the action of the pushing spring 52, so that the sliding plate 47 and the fixed plate 46 cooperate to clamp the opening of the filter bag 22, thereby closing the opening of the filter bag 22. At the same time, the moving rod 51 is pulled back, and the positioning block 53 is inserted and installed on the moving rod 51 under the action of gravity for positioning, thereby opening the opening of the filter bag 22.

[0066] Reference Figure 3 and Figure 4 When the filter bag 22 needs to be replaced or cleaned, push the positioning block 53 upward and disengage it from the moving rod 51. The sliding plate 47 approaches the fixed plate 46 and clamps the opening of the filter bag 22, thereby closing the opening of the filter bag 22. Then pull the connecting plate 41 to remove the filter bag 22 together. Next, snap the snap block 15 containing the new filter bag 22 onto the snap slot 18.

[0067] Reference Figure 3 and Figure 4Move the connecting plate 41 to the cleaning area for cleaning. Pull the moving rod 51 to move the sliding plate 47 away from the fixed plate 46, so that the positioning block 53 is inserted and installed on the moving rod 51 for positioning, thereby opening the bag opening of the filter bag 22. Then rotate the positioning plate 43 away from the positioning teeth 42, and then the filter bag 22 can be removed for cleaning. After cleaning, pass the bag opening of the filter bag 22 through the connecting hole 44, so that the positioning teeth 42 on the fixed plate 46 and the sliding plate 47 pass through the filter holes of the filter bag 22. Finally, rotate the positioning plate 43 closer to the positioning teeth 42, so that the positioning teeth 42 are inserted and installed on the positioning groove, and the positioning plate 43 presses against the filter bag 22 for positioning. This is to make it available for subsequent replacement of the filter bag 22, thereby realizing the cleaning and replacement of the filter bag 22 and improving the filtration efficiency and effect of the filter bag 22.

[0068] Reference Figure 1 and Figure 2 The filtration mechanism 2 also includes a guide plate 23, a water guide pipe 24, and an adjustment component 3. The top of the guide plate 23 is rotatably mounted on the rotating shaft 14, and the bottom of the guide plate 23 is tilted downward and set towards the side away from the frame 21. At the same time, the bottom of the guide plate 23 is positioned against the bottom of the drainage ditch body 1 under the action of gravity, and the guide plate 23 completely blocks the drainage space 16. When the water flowing into the drainage ditch body 1 impacts the guide plate 23, it will push the guide plate 23 to maintain a downward rotation trend. The guide plate 23 is used to guide the water in the drainage ditch body 1 into the water channel 12. Then the water enters the filter bag 22 through the water passage hole 13 for filtration. Then the filtered water enters the next section of the drainage ditch body 1 for discharge after passing through the drainage space 16.

[0069] Reference Figure 1 and Figure 2 The water guide pipe 24 is fixedly installed on the outer wall of the drainage ditch body 1, and the water guide pipe 24 is connected to the inside of the drainage ditch body 1 located in the drainage space 16. At the same time, the other end of the water guide pipe 24 is used to connect to the filter tank. After the guide plate 23 rotates, a flow space is formed between it and the drainage ditch body 1 located below the guide plate 23. Therefore, the initial state of the flow space is zero area. The flow space is connected to the drainage space 16. The adjustment component 3 is set on the frame 21 and adjusts the size of the flow space according to the water level.

[0070] Reference Figure 1 and Figure 2The adjusting assembly 3 includes a buoyancy rod 31, a buoyancy plate 32, and an adjusting rod 33. The buoyancy rod 31 is vertically slidably mounted on the side wall of the frame 21 near the rotating shaft 14, and two buoyancy rods 31 are spaced apart and located at both ends of the length of the frame 21. The buoyancy plate 32 is fixedly mounted on the top of the two buoyancy rods 31, and the buoyancy plate 32 is located below the top of the frame 21 and above the water channel 12. Under the action of water buoyancy, the buoyancy plate 32 drives the buoyancy rods 31 to move upward. A guide strip 25 is fixedly mounted on the upper surface of the guide plate 23. Two guide plates 23 are provided and located at the two buoyancy rods 31. The guide strip 25 has a downwardly inclined guide hole 26. The adjusting rod 33 is fixedly mounted on the bottom end of the buoyancy rod 31, and the adjusting rod 33 is slidably mounted on the guide hole 26 and can rotate on the guide hole 26.

[0071] Reference Figure 1 and Figure 2 The buoyancy rod 31 moves up and down, causing the adjusting rod 33 to move. The adjusting rod 33 moves on the guide hole 26, thereby causing the guide plate 23 to rotate and adjust the size of the flow space. When the water volume is large, the water level rises. When the water level rises above the water passage 12, it pushes the buoyancy plate 32 to move upward. The upward movement of the buoyancy plate 32 causes the guide plate 23 to rotate, thereby causing the flow space to gradually increase from zero. Therefore, some water in the drainage ditch body 1 continues to enter the filter bag 22 through the water passage 13 for filtration, while another part of the water enters the drainage space 16 through the flow space and impacts the filter bag 22. The filter bag 22 blocks the water and guides it to the water guide pipe 24, allowing more water to enter the filtration tank for recycling. The remaining water is discharged into the next section of the drainage ditch body 1 through the drainage space 16.

[0072] Reference Figure 1 and Figure 2 After the water level drops, the guide plate 23 rotates under the influence of gravity and the impact of water on the guide plate 23 until the guide plate 23 presses against the main body 1 of the drainage ditch for positioning. Then, the water continues to be guided to the filter bag 22 for filtration. Therefore, when the water volume is small, the water is filtered through the filter bag 22 as much as possible. When the water flow is large, the water is diverted through multiple channels. At the same time, more water is discharged into the filter pool through the water pipe 24, thereby further improving the drainage function of the drainage ditch.

[0073] Reference Figure 2 and Figure 5The overflow hole 11 is located above the filter bag 22. The frame 21 is also equipped with a guide assembly 6 and a blocking assembly 7. The guide assembly 6 includes a guide plate 61 and a torsion spring 62. The first rotating column 63 and the second rotating column 64 are rotatably installed from top to bottom on the side wall of the frame 21 away from the guide plate 23. The first rotating column 63 and the second rotating column 64 are located below the overflow hole 11 and their axes are parallel to the axis of the rotating shaft 14. The bottom of the guide plate 61 is rotatably installed on the first rotating column 63, and the top of the guide plate 61 extends vertically upward to be flush with the upper surface of the frame 21.

[0074] Reference Figure 2 and Figure 5 The torsion spring 62 is sleeved on the first rotating column 63 and its two ends are fixedly connected to the guide plate 61 and the frame 21 respectively. At the same time, the torsion spring 62 causes the guide plate 61 to press against the frame 21, and the guide plate 61 blocks the overflow hole 11 and blocks the water entering the overflow hole 11, so that more water can be filtered through the filter bag 22. When the water volume increases and enters the overflow hole 11, the water exerts a pushing force on the guide plate 61. When the pushing force is greater than the torsion of the torsion spring 62, the guide plate 61 moves away from the frame 21 and a gap is formed between the guide plate 61 and the frame 21, and the water can overflow through the gap. As the water volume continues to increase, the water can even flow over the top of the guide plate 61 into the next section of the drainage ditch body 1 for discharge. When the water volume decreases and the pushing force on the guide plate 61 decreases, the guide plate 61 rotates under the action of the torsion spring 62 and presses against the frame 21 to block the overflow hole 11.

[0075] Reference Figure 2 and Figure 5 Fixing blocks 73 are fixedly installed on the side wall of the frame 21 at both ends of the second rotating column 64. The second rotating column 64 is rotatably mounted on the side wall opposite to the two fixing blocks 73. A blocking block is fixedly installed on the side wall of the frame 21 below the second rotating column 64. The blocking assembly 7 includes a blocking plate 71 and a locking member 72. The top of the blocking plate 71 is fixedly installed on the second rotating column 64, and the blocking plate 71 is positioned on the blocking block, so that the bottom of the blocking plate 71 is tilted downward and facing away from the frame 21. At the same time, the bottom of the blocking plate 71 extends to the frame. A water passage space 17 is formed below the body 21 and between it and the drainage ditch body 1 located below the baffle plate 71. After filtration, the water passes through the drainage space 16 and the water passage space 17 in sequence and then enters the next section of the drainage ditch body 1. At the same time, the baffle plate 71 can also block the water passing through the drainage space 16 to a certain extent, so that more water is discharged into the filter tank through the water guide pipe 24. When the water volume is large, it impacts the baffle plate 71 and causes it to rotate, thereby increasing the size of the water passage space 17, accelerating the speed at which water enters the next section of the drainage ditch body 1, and improving the drainage function of the drainage ditch.

[0076] Reference Figure 2 and Figure 5The side wall of the connecting plate 41 away from the rotating shaft 14 extends to the baffle plate 71. When the baffle plate 71 is placed on the baffle block, it abuts against the connecting plate 41 for positioning, reducing the probability that the movement of the connecting plate 41 will cause the filter bag 22 to move, thus improving the filtration effect of the filter bag 22. The locking piece 72 is set on the fixed block 73 and is used to lock the baffle plate 71 when replacing the filter bag 22. The baffle plate 71 is rotated above the connecting plate 41, and the locking piece 72 is locked. Then the connecting plate 41 can be removed to replace the filter bag 22. After replacement, the locking piece 72 is unlocked, and the baffle plate 71 rotates back under gravity to be placed on the baffle block and the connecting plate 41 for positioning. The locking piece 72 is a locking screw, which is threaded onto the fixed block 73 and abuts against the second rotating column 64 for positioning.

[0077] Reference Figure 2 and Figure 5 Magnet blocks 8 are fixedly installed on the side walls of guide plate 61 and baffle plate 71 away from frame 21, and the two magnet blocks 8 can be attracted together to position guide plate 61 and baffle plate 71. When guide plate 61 and baffle plate 71 are impacted by water, the two magnet blocks 8 are brought closer to each other until they are attracted together for positioning. At the same time, as the impact force of water on guide plate 61 and baffle plate 71 decreases, guide plate 61 and baffle plate 71 move away from each other under the torsion of torsion spring 62 and the gravity of baffle plate 71, so that the two magnet blocks 8 move away from each other, and guide plate 61 and baffle plate 71 return to their original position.

[0078] The working principle of this application embodiment is as follows:

[0079] Initially, the rainwater volume is small and contains many impurities. Therefore, the rainwater enters the main body of the drainage ditch 1, and the guide plate 23 directs the rainwater to the filter bag 22 for filtration. The filtered water then enters the filtration tank through the water pipe 24 for sedimentation and recycling. Meanwhile, water that does not have time to enter the water pipe 24 moves to the next section of the main body of the drainage ditch 1 for filtration through the drainage space 16 and the water passage space 17. Impurities accumulate in the filter bag 22 under gravity. As the amount of impurities in the filter bag 22 increases, the impurities are spread flat on the bottom of the main body of the drainage ditch 1 through the filter bag 22 for positioning, thereby improving the filtration effect of the filter bag 22.

[0080] During the later stages of rainfall, the water level rises above the water channel 12 and enters the overflow hole 11. The water pushes the buoyancy plate 32 upward, which in turn drives the guide plate 23 to rotate, creating a flow space that expands with the increase in water volume. This allows water to flow into the drainage space 16 for discharge. Simultaneously, the water impacts the guide plate 61 and the baffle plate 71, causing the guide plate 61 to rotate downward and the baffle plate 71 to rotate upward. This allows for discharge through multiple channels and increases the channel area. When the water level drops, the guide plate 23 returns to its original position. The drain space 16 is blocked, allowing more water to enter the filter bag 22 for filtration. At the same time, the guide plate 61 presses against the frame 21 to block the overflow hole 11, and the baffle plate 71 rotates and presses against the baffle block to block the water, allowing more water to pass through the filter bag 22 for filtration. At the same time, more water also enters the filter tank through the water pipe 24. This achieves the goal of filtering as much water as possible through the filter bag 22 when the water volume is low, and increasing the water discharge channel and the area of ​​the channel when the water volume increases, thereby improving the drainage function of the drainage ditch.

[0081] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
