Description

Technical Field

[0001] This utility model relates to the field of diversion well technology, and more specifically, to a hydraulically controlled diversion device for diversion wells. Background Technology

[0002] A diversion well is a device used to separate, guide, or regulate water flow. It typically has multiple inlets and outlets, distributing fluids to different pipes or containers according to varying needs. In municipal engineering, it is mainly used in combined sewer systems to separate rainwater and sewage, preventing direct discharge of sewage into natural water bodies and improving urban flood control and drainage capabilities. Hydraulically controlled diversion devices primarily employ hydraulically operated bottom-opening weirs. These weirs are used in pipelines, culverts, or channels for water flow control. The opening and closing of the weir plates is controlled by hydraulic cylinders. A hydraulically operated bottom-opening weir system mainly consists of the weir gate, a hydraulic system, an ultrasonic level gauge, and a control system. The opening and closing cylinders drive the gate plates to rise and fall as needed and can stop at any position to control the water flow or regulate the upstream water level. The ultrasonic level sensor detects the water level on both sides of the weir gate and converts it into an electrical signal, which is then sent to the control system. The control system drives the cylinders on both sides of the weir gate, causing the weir plates to slide up and down in the guide groove.

[0003] Currently, hydraulically operated bottom-opening weirs divert liquids by adjusting their opening degree during vertical movement. This traditional method of liquid diversion has a significant drawback: sludge clogging. Sludge accumulates on the weir's water-retaining surface during flow, so even after the entire gate is opened, the accumulated sludge layer still obstructs water flow, affecting the diversion efficiency. Therefore, we propose a hydraulically controlled diversion device for diversion wells. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a liquid-controlled diversion device for diversion wells to solve the current technical problem of sludge layer affecting the smoothness of water flow.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a hydraulically controlled diversion device for a diversion well, comprising a weir gate and a cleaning device, wherein the cleaning device is located on the water-retaining surface of the weir gate; The cleaning device includes an extension plate, a bending section, and two disturbance sections. The bending section is located on the top surface of the extension plate, and the disturbance sections are located on the bottom surface of the extension plate. The cleaning device also includes a support mechanism and a drive mechanism. The support mechanism includes a guide rod and a guide block. The guide block has a through hole that adapts to the shape of the outer wall of the guide rod, and the guide rod is located inside the through hole. The driving mechanism includes a fixed base, a storage groove, and a driving roller. The storage groove is opened on the outer surface of the fixed base. Assembly grooves are opened on both sides of the inner wall of the storage groove. The driving roller is located inside the assembly groove and protrudes from the inside of the storage groove. The driving roller is in contact with the curved part.

[0006] Preferably, the weir gate includes a door frame and a door panel, with the door panel disposed inside the door frame.

[0007] Preferably, the curved portion includes a plurality of curved grooves, the curved grooves having opposite bending directions, and adjacent curved grooves having an S-shaped structure design.

[0008] Preferably, the outer surface of the extension plate is provided with equidistantly distributed water passage holes, the water passage holes adopt a through-hole design, the inner wall of the water passage holes adopts a rectangular structure design, and the two outer walls of the extension plate are fixedly connected with baffle plates, which penetrate into the water passage holes. The outer side of the extension plate is divided into a sludge section and a clean water section by the baffle plates.

[0009] Preferably, the disturbance part is located on the bottom surface of the extension plate, and the disturbance part is provided with a plurality of partition cavities. The plurality of partition cavities are all designed with a rectangular structure, and the inner wall of the partition cavity is provided with a rectangular array of drain holes. The drain holes are designed to be through-hole.

[0010] Preferably, assembly plates are fixedly connected to both outer walls of the extension plate, and the assembly plates are fixedly connected to the disturbance part and the end of the guide block, respectively; The support mechanism also includes two positioning seats, which are fixedly connected to the outer wall of the door frame. The guide rod is located inside the positioning seat, and both ends of the guide rod are threaded through the positioning seat and connected with nuts. Both sides of the outer wall of the guide block are fixedly connected with shields. The shields include several folded parts, which are designed with a raised arc shape. The end of the shield away from the guide block is fixedly connected to the inner wall of the positioning seat.

[0011] Preferably, the fixing seat is screwed to the top surface of the door panel, the storage groove protrudes from the outside of the door panel, the inner wall of the assembly groove is threaded with a positioning screw, and the drive roller is rotatably mounted on the outer surface of the positioning screw.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model designs a cleaning device whose disturbance part moves laterally back and forth with the extension plate. This disturbance part can physically divide the sludge accumulated on the weir gate's water-blocking surface and quickly discharge the disturbed sludge-containing wastewater. This dynamic cleaning method avoids the problem of sludge static retention forming a dense blockage layer in traditional devices, ensuring that the water flow channel is always unobstructed, significantly improving diversion efficiency, and solving the problem of sludge layer affecting the smoothness of water flow.

[0013] 2. This utility model also designs an S-shaped structure with adjacent bending grooves in opposite directions. When the door panel drives the drive roller to rise and fall vertically, the contact between the drive roller and the bending groove will generate a horizontal reaction force. This allows the extension plate to move laterally without an additional power source. Based on the disturbance of sludge by the lateral movement, this "force-driven" design not only simplifies the device structure but also reduces energy consumption. At the same time, it ensures that the cleaning action is synchronized with the opening and closing of the door panel, achieving the linkage effect of "cleaning as soon as the door is opened". This avoids sludge remaining and blocking water flow after the door panel is opened. The extension plate is clearly divided into a sludge section and a clean water section. When cleaning sludge in the disturbed section, the baffle plate can physically block the disturbed sludge-containing sewage, allowing the sewage in the sludge section to be discharged into the municipal sewage channel at the beginning of the door opening, preventing it from polluting the clean water section. It also ensures that the water flowing from the upper part of the extension plate is cleaner, further solving the problem of rainwater mixing with sludge and being discharged together.

[0016] like Figures 1 to 6As shown, this utility model relates to a hydraulically controlled diversion device for a diversion well, including a weir gate 1 and a cleaning device 2. The cleaning device 2 is located on the water-blocking surface of the weir gate 1. The cleaning device 2 includes an extension plate 21, a bending part 22, and two disturbance parts 26. The bending part 22 is located on the top surface of the extension plate 21, and the disturbance parts 26 are located on the bottom surface of the extension plate 21. The cleaning device 2 also includes a support mechanism 3 and a drive mechanism 4. The support mechanism 3 includes a guide rod 32 and a guide block 33. The guide block 33 has a through hole adapted to the shape of the outer wall of the guide rod 32, and the guide rod 32 is located inside the through hole. The drive mechanism 4 includes a fixed seat 41, a receiving groove 42, and a drive roller 45. The receiving groove 42 is opened on the outer surface of the fixed seat 41. Assembly grooves 43 are opened on both sides of the inner wall of the receiving groove 42. The drive roller 45 is located inside the assembly groove 43 and protrudes from the receiving groove 42. The drive roller 45 is in contact with the bending part 22. The disturbance part 26 of the cleaning device 2 can separate and discharge sludge by moving laterally with the extension plate 21, so as to avoid the sludge layer from affecting the water flow. The extension plate 21 can be moved by opening and closing the weir gate 1 without additional power. It can also separate the sludge part and the clean water part, prevent sewage from polluting the clean water, and improve the diversion efficiency and water cleanliness.

[0017] Specifically, the weir gate 1 includes a gate frame 11 and a gate panel 12, with the gate panel 12 located inside the gate frame 11. The gate frame 11 can be fixed to the pre-set installation position of the diversion well using expansion bolts to ensure that the entire weir gate 1 is firmly installed. A rubber sealing ring can be installed between the gate panel 12 and the gate frame 11 to further improve the sealing performance and prevent water leakage. The gate panel 12 can be driven vertically by a hydraulic drive device used inside the weir gate 1.

[0018] Furthermore, the bending portion 22 includes several bending grooves, which have opposite bending directions and adjacent bending grooves have an S-shaped structure design. The depth and width of the bending grooves can be adapted to the diameter of the drive roller 45 to ensure that the drive roller 45 can stably enter the bending groove and achieve reliable transmission. During the vertical movement of the fixed base 41 carrying the drive roller 45, the bending portion 22 of the extension plate 21 can drive the extension plate 21 to reciprocate laterally in the horizontal direction.

[0019] Furthermore, the outer surface of the extension plate 21 is provided with equidistantly distributed water passage holes 23. The water passage holes 23 adopt a through-hole design, and the inner wall of the water passage holes 23 adopts a rectangular structure design. Both sides of the outer wall of the extension plate 21 are fixedly connected to the baffle plates 24, and the baffle plates 24 penetrate into the water passage holes 23. The exterior of the extension plate 21 is divided into a sludge section and a clean water section by the baffle plates 24. The spacing of the water passage holes 23 can be adjusted according to the actual water flow velocity and sludge content. The spacing is set to 5-10cm, which can ensure water flow efficiency and, together with the baffle plates 24, block the sludge-containing sewage. The baffle plates 24 are made of stainless steel, which can physically block the sewage from being disturbed and spread by the sludge, prevent the sewage from spreading to the clean water section, ensure that the liquid in the clean water section at the upper end of the extension plate 21 is relatively clean, and reduce the diffusion range when the sewage is disturbed.

[0020] It is worth noting that the disturbance part 26 is located on the bottom surface of the extension plate 21. The disturbance part 26 contains several partitioned cavities, each with a rectangular structure. The inner walls of these cavities are provided with a rectangular array of drain holes 27, which are through-holes. The number and size of the partitioned cavities can be determined based on the overall dimensions of the disturbance part 26. Each partitioned cavity has a side length of 8-15cm, which helps to divide the sludge and ensures effective disturbance of the sludge when the disturbance part 26 moves laterally with the extension plate 21. The diameter of the drain holes 27 is set to 2-5cm to ensure the discharge of wastewater containing sludge.

[0021] It is worth mentioning that assembly plates 25 are fixedly connected to both outer walls of the extension plate 21. The assembly plates 25 are fixedly connected to the disturbance part 26 and the end of the guide block 33 respectively. The support mechanism 3 also includes two positioning seats 31. The positioning seats 31 are fixedly connected to the outer wall of the door frame 11. The guide rod 32 is located inside the positioning seat 31, and both ends of the guide rod 32 are threaded through the positioning seat 31 and connected with nuts. The outer walls of both sides of the guide block 33 are fixedly connected to shields 34. The shields 34 include several folded parts. The several folded parts are designed with a raised arc-shaped structure. The end of the shields 34 away from the guide block 33 is fixedly connected to the inner wall of the positioning seat 31. The assembly plate 25 is welded to the disturbance part 26 and the guide block 33 respectively to ensure the overall structural connection strength. The guide rod 32 is made of stainless steel optical shaft material. The guide rod 32 and the guide block 33 can maintain the lateral movement trajectory of the extension plate 21 and the assembly plate 25, ensuring the smooth lateral movement of the extension plate 21 and the assembly plate 25. The shield 34 is made of silicone or rubber material, which has good flexibility and corrosion resistance. The arc-shaped folding part ensures that the shield 34 can be folded and extended, ensuring that the shield 34 can cover the mating area of ​​the guide rod 32 and the guide block 33, and preventing mud or sand from affecting the smooth movement of the guide block 33 outside the guide rod 32.

[0022] It is worth noting that the fixing seat 41 is screwed to the top surface of the door panel 12, the storage groove 42 protrudes from the outside of the door panel 12, and the inner wall of the assembly groove 43 is threaded with a positioning screw 44. The drive roller 45 is rotatably mounted on the outer surface of the positioning screw 44. The positioning screw 44 can limit the rotation position of the drive roller 45, ensuring that the drive roller 45 is stably positioned inside the assembly groove 43.

[0023] Working Principle: This embodiment provides a hydraulically controlled diversion device for a diversion well. In use, the door frame 11 of the weir gate 1 is fixed at a preset installation position in the diversion well by expansion bolts, ensuring that the overall device is stably installed. The rubber sealing ring between the door frame 11 and the door panel 12 can prevent water leakage. Then the hydraulic driving device matched with the weir gate 1 is started, and the device drives the door panel 12 to perform vertical lifting movement along the door frame 11, so as to realize basic control of the water flow in the diversion well. When the door panel 12 moves vertically, since the fixing seat 41 is connected to the top surface of the door panel 12 by screws, the door panel 12 drives the fixing seat 41 to move vertically synchronously. The driving roller 45 rotatably installed in the accommodating groove 42 on the outer surface of the fixing seat 41 through the positioning screw 44 also moves vertically synchronously therewith. The driving roller 45 is always kept in contact with the curved portion 22 on the top surface of the extension plate 21 in the sewage cleaning device 2. During the vertical movement of the driving roller 45, the S-shaped curved groove generates a horizontal counterforce on the driving roller 45, thereby driving the extension plate 21 to perform reciprocating transverse movement in the horizontal direction. The outer walls on both sides of the extension plate 21 are respectively fixedly connected with the disturbance portion 26 and the guide block 33 through the assembling plate 25. The guide block 33 is provided with a through hole adapted to the shape of the outer wall of the guide rod 32 inside and is sleeved on the guide rod 32. Both ends of the guide rod 32 are fixed on the outer wall of the door frame 11 through positioning seats 31. This supporting structure can accurately limit the transverse movement track of the extension plate 21, ensuring that the movement is smooth and stable. Meanwhile, the shielding covers 34 on both sides of the guide block 33 fold or expand along with the movement of the guide block 33, and always cover the matching area of the guide rod 32 and the guide block 33, preventing sludge and sediment from entering and affecting the matching fluency of the two components. The disturbance portion 26 on the bottom surface of the extension plate 21 moves synchronously with the reciprocating transverse movement of the extension plate 21. A plurality of rectangular separating cavities inside the disturbance portion 26 can separate the sludge accumulated on the water retaining surface of the weir gate 1, and realize disturbance and dispersion of the sludge inside the separating cavities. Since in municipal drainage, before rainfall and at the initial stage of rainfall, the weir gate 1 for discharging clean rainwater is in a closed state, the opening of the door panel 12 and the sewage after sludge disturbance can be discharged along the sewage drainage channel, ensuring that the sludge on the water retaining surface of the door panel 12 can be cleaned, providing guarantee for the subsequent discharge of clean rainwater. Meanwhile, the sewage discharge holes 27 on the inner wall of the separating cavity can discharge the sludge-containing sewage after being disturbed, realizing effective disturbance and cleaning of the sludge layer, and preventing retained sludge from blocking water flow. The equally-spaced water through holes opened on the outer surface of the extension plate 21 ensure water passing efficiency, while the blocking plates 24 on the two side outer walls penetrate into the water through holes 21, dividing the upper and lower sides outside the extension plate 21 into a sludge part and a clean water part, which can physically block the sludge-containing sewage that has been disturbed and diffused, prevent it from diffusing to the clean water part, ensure that the liquid in the clean water part at the upper end of the extension plate 21 is relatively clean, and reduce the diffusion range during sewage disturbance.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
