Description

Technical Field

[0001] This utility model belongs to the technical field of hydraulic regulation, specifically relating to a hydraulic regulation device for artificial wetlands with automatic dredging function. Background Technology

[0002] In recent years, with the deepening of ecological and environmental protection concepts, constructed wetlands, as a highly efficient and low-cost wastewater treatment technology, have been widely used in urban and rural water environment management. Constructed wetlands simulate natural wetland ecosystems, combining the synergistic effects of plants, microorganisms, and substrates to achieve efficient removal of pollutants such as organic matter, nitrogen, and phosphorus from wastewater. Hydraulic regulation is a key aspect of constructed wetland operation; by optimizing water flow distribution, retention time, and load allocation, the purification efficiency and stability of the wetland can be significantly improved.

[0003] Currently, in constructed wetland systems, water supply pipelines are connected to wetland units using flange-type sealing. The water inside the wetland is regulated and controlled by electric valve groups embedded in the outer wall of the pipeline. When the valve is closed, the upstream water forms an instantaneous water pressure accumulation in the back cavity of the valve plate. At the same time, the suspended silt particles carried by the water flow form a silt layer at the bottom of the pipeline due to the sudden drop in flow velocity. This silt gradually spreads upward to the valve sealing surface, causing an increase in the resistance to valve stem rotation, and in severe cases, causing valve core jamming. Utility Model Content

[0008] As a preferred embodiment of this utility model, four rectangular plates are fixedly connected to the inner wall of the dredging frame, and the rectangular plates help to separate the dredging frame.

[0009] In a preferred embodiment of this utility model, the limiting plate is L-shaped, the limiting plate is attached to the sewage pipe, and the size of the lower arc plate of the limiting plate is larger than the size of the sewage trough.

[0010] In a preferred embodiment of this invention, all of the inclined grooves are triangular, and the striking frame abuts against the inclined surface of the inclined groove.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Example 1 Reference Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a hydraulic control device for artificial wetlands with automatic sludge removal function, including a cleaning component, including a sewage pipe 10. A control valve 11 is installed on the surface of the sewage pipe 10. A sewage trough 12 is opened on the inner wall of the sewage pipe 10. The arc surface of the sewage pipe 10 is rotatably connected to a sludge removal frame 13 that helps to automatically remove sludge. A power component 14 is provided between the sewage pipe 10 and the sludge removal frame 13. A limit plate 15 is fixedly connected to the lower side of the sewage pipe 10. A striking component 16 is provided between the limit plate 15 and the sludge removal frame 13.

[0020] In the constructed wetland hydraulic control system, the control valve 11, as the core actuator, can precisely control the opening and closing status of the sewage pipe 10. After the sewage pipe 10 completes the flange-type sealing installation with the wetland unit, it can drive the sludge removal frame 13 to rotate on a fixed axis according to the preset cycle, so that the four independent chambers inside the sludge removal frame 13 rotate sequentially to the area directly below the sewage trough 12. At the same time, the knocking component 16 integrated inside the limit plate 15 will cause the sludge to be separated from the inner wall of the chamber by high-frequency vibration waves when the sludge chamber rotates to the external sludge removal position, which significantly improves the self-weight detachment efficiency of the sludge.

[0021] Furthermore, the power assembly 14 includes a mounting bracket 141 fixedly connected to the surface of the sewage pipe 10. A motor 142 is mounted on the inner wall of the mounting bracket 141. A first gear 143 is fixedly connected to the output end of the motor 142. Several meshing grooves are provided on the side of the sludge removal frame 13 near the motor 142. The meshing teeth of the first gear 143 are adapted to the meshing grooves of the sludge removal frame 13. The striking assembly 16 includes two striking frames 161 rotatably connected to the surface of the limiting plate 15. A torsion spring 162 is sleeved on the shaft of each of the two striking frames 161. The two ends of the torsion spring 162 are fixedly connected to the limiting plate 15 and the striking frame 161, respectively. Several inclined grooves 163 are provided on the side of the sludge removal frame 13 near the striking frame 161.

[0022] The motor 142 controls the first gear 143 to rotate in stages, thereby assisting the four chambers of the sludge removal frame 13 to contact the lower side of the sewage trough 12 in sequence. During this process, the sludge inside can flow smoothly into the chamber. As the sludge removal frame 13 continues to rotate and switch, the sludge is effectively discharged to the sewage pipe 10, ensuring that the sludge does not come into contact with the valve area. At the same time, with the help of the torsion spring 162 and the knocking frame 161, when the chamber containing the sludge moves to the outside, a vibration effect can be generated, and then the sludge can smoothly detach from the sludge removal frame 13 and fall to the ground.

[0023] Preferably, four rectangular plates are fixedly connected to the inner wall of the sludge removal frame 13, and the rectangular plates help to separate the sludge removal frame 13. The limiting plate 15 is L-shaped, and the limiting plate 15 fits against the sewage pipe 10, and the size of the lower arc plate of the limiting plate 15 is larger than the size of the sewage trough 12. Several inclined grooves 163 are all triangular, and the striking frame 161 abuts against the inclined surface of the inclined groove 163.

[0024] It should be noted that the sludge removal frame 13, with its multi-chamber partition design, forms multiple anti-permeability barriers through the rigid isolation structure of the rectangular plates, effectively blocking the migration and permeation of sludge between chambers. At the same time, the rectangular partition plates adopt an engineering design with a 12° tilt angle. When the chamber containing sludge rotates with the sludge removal frame 13 to the sewage discharge position, it can guide the sludge to form a directional flow by means of the combined effect of gravitational potential energy and the tilted plate surface, thus achieving automatic sludge discharge. The limiting plate 15 is L-shaped, forming an all-round wrapping barrier on the lower side of the sludge removal frame 13. Its arc surface is tightly attached to the sludge removal frame 13, which can ensure zero leakage of solid and liquid two phases throughout the sludge collection process. The inclined groove 163 (45° tilt angle), with its isosceles triangular structure, contacts the round rod position of the striking frame 161 through its inclined guide surface. It can efficiently guide the striking frame 161 to automatically leave the inclined groove 163 area along a preset trajectory. With the elastic potential energy storage and release mechanism of the torsion spring 162, it repeatedly impacts the surface of the sludge removal frame 13 to achieve a vibration effect.

[0025] In use, after the sewage pipe 10 is connected to the constructed wetland pipeline, the motor 142 can be started. The output end of the motor 142 rotates counterclockwise, driving the first gear 143 to rotate synchronously. At the same time, the meshing groove on one side of the sludge removal frame 13 meshes with the first gear 143. Through the rotation of the first gear 143, the sludge removal frame 13 can rotate clockwise. The motor 142 can be started in stages to achieve the cyclic switching of the four chambers of the sludge removal frame 13. When one of the chambers is under the sewage trough 12, the motor 142 is turned off. At this time, the sludge inside the sewage pipe 10 will enter the chamber created by the sludge removal frame 13 and the sewage pipe 10. The lower limit plate 15 blocks the sludge and prevents water leakage. Then the motor 142 is started again to help the sludge removal frame 13 achieve the chamber status. At the same time, when equipped with When the sludge chamber is disengaged from the limiting plate 15, the sludge inside can flow outward, thereby achieving an automatic cleaning effect. When the chamber is adjusted by rotation, the striking frame 161, under the effect of the torsion spring 162, can repeatedly strike the inclined surface of the inclined groove 163, thereby causing the sludge cleaning frame 13 to vibrate, reducing the tightness of the sludge adhering to the sludge cleaning frame 13 and the outer wall of the sewage pipe 10. The striking frame 161, guided by the inclined surface of the inclined groove 163, will press against the outer arc surface of the sludge cleaning frame 13, achieving a power storage effect. Then, when the inclined groove 163 is on the surface, the torsion spring 162 drives the striking frame 161 to achieve a striking effect. After a period of time, the sludge is automatically discharged, and the motor 142 is restarted to replace the chamber. By setting repeated switching, the automatic cleaning of the sludge inside the sewage pipe 10 can be achieved.

[0026] Example 2 Reference Figures 1-6 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a discharge component, including two side plates 20 fixedly connected to the arc surface of the sewage pipe 10. The surfaces of the two side plates 20 are rotatably connected to a rotating shaft 21. A scraper 22 is fixedly connected to the surface of the rotating shaft 21. A telescopic component 23 is provided between the sewage pipe 10 and the rotating shaft 21. An adapter component 24 is provided between the sludge removal frame 13 and the rotating shaft 21. The telescopic component 23 includes a base 231 fixedly connected to the surface of the sewage pipe 10. An extension plate 232 is slidably connected to the inner wall of the base 231. A spring 233 is provided between the inner side of the base 231 and the extension plate 232. A second gear 234 is rotatably connected to the side of the extension plate 232 near the rotating shaft 21. The meshing teeth of the second gear 234 are adapted to the meshing groove of the sludge removal frame 13. The rotating shaft 21 is fixedly connected to the second gear 234. The adapter component 24 includes a circular plate 241 fixedly connected to the surface of the rotating shaft 21, and four guide plates 242 fixedly connected to the surface of the sludge removal frame 13.

[0027] Specifically, when the sludge removal frame 13 rotates to switch chambers, the elastic coordination mechanism of the spring 233 and the extension plate 232 can effectively drive the second gear 234 to mesh with the sludge removal frame 13, causing the second gear 234 to complete a counterclockwise rotation under the drive of the sludge removal frame 13, and linking the scraper 22 to perform synchronous rotation, thereby achieving thorough scraping and removal of the sludge inside the chamber. This linkage process significantly improves the discharge efficiency of sludge, shortens the switching time of the chamber, and ultimately significantly enhances the sludge cleaning efficiency inside the sewage pipe 10.

[0028] Preferably, the scraper 22 is L-shaped, and the outermost edge of the scraper 22 abuts against the drain pipe 10. The four guide plates 242 are all trapezoidal, and the height of the four guide plates 242 is greater than the length of the scraper 22 inside the sludge removal frame 13.

[0029] It should be noted that the special structure of the scraper 22, with its "L"-shaped design, can efficiently guide the flow of sludge. At the same time, when sludge is deposited on the surface of the scraper 22, it also acts as a limit, effectively preventing sludge backflow or accumulation, ensuring that the sludge is quickly and thoroughly discharged from the chamber of the sludge removal frame 13, significantly improving the sewage discharge efficiency. In addition, when the guide plate 242 contacts the circular plate 241, the interaction between the inclined surface of the trapezoidal guide plate 242 and the circular plate 241 precisely drives the position adjustment of the rotating shaft 21, so that the scraper 22 automatically moves away from the sludge removal frame 13, avoiding any interference with the normal operation of the sludge removal frame 13 to switch chambers, thereby ensuring the stability and continuity of equipment operation. This mechanism further optimizes the sludge removal process, shortens the switching time, and enhances the overall sludge removal efficiency.

[0030] In operation, the output of motor 142 drives the first gear 143 to rotate, which in turn drives the sludge removal frame 13 to rotate, thus switching chambers. When the guide plate 242 on the surface of the sludge removal frame 13 contacts the circular plate 241, the scraper 22 moves away from the sludge removal frame 13 under the guidance of the guide plate 242, ensuring that the normal rotation of the sludge removal frame 13 is undisturbed. When the chamber moves to the side of the rotating shaft 21, the guide plate 242 moves away from the circular plate 241, and the action of the spring 233 drives the extension plate 232 to slide towards the base 231, while simultaneously causing the rotating shaft 21 and the scraper 22 to move, helping the scraper 22 to smoothly enter the chamber. At the same time, the second gear 234 precisely engages with the meshing groove of the sludge removal frame 13. As the sludge removal frame 13 rotates, it drives the second gear 234 to rotate, synchronously driving the rotating shaft 21 to rotate counterclockwise, so that the scraper 22 can efficiently discharge the sludge inside the chamber. In this way, the sludge can be automatically discharged and guided out by the scraper 22, significantly improving the discharge effect. Furthermore, the motor 142 accelerates the chamber switching speed, simultaneously improves the sludge cleaning efficiency, significantly reduces the sludge residue inside the sewage pipe 10, and achieves rapid cleaning of the sludge inside the pipe.

[0031] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
