Description

Technical Field

[0001] This invention relates to the field of river ecological restoration technology, and more specifically, to a river ecological restoration device. Background Technology

[0002] In the existing field of river ecological restoration technology, aeration systems play a crucial role as a core component. Traditional aeration devices typically use fixed aeration discs for oxygen transfer to promote the growth of microorganisms and the degradation of organic matter in the water. Under ideal conditions, these devices can effectively increase the dissolved oxygen content in the water, accelerate the decomposition of pollutants, and promote the self-repair of the ecosystem. However, these aeration discs have technical limitations—their air outlet size is fixed and cannot be dynamically adjusted according to the actual needs of the water body. This leads to a significant reduction in aeration efficiency and insufficient oxygen transfer efficiency when facing different water depths, different pollution levels, different seasonal temperature changes, and different water flow conditions, thus affecting the effectiveness of the entire ecological restoration system.

[0003] To address this technical challenge, an adjustable aeration system needs to be developed to improve the efficiency and adaptability of river ecological restoration. In practical applications, there are significant differences in oxygen demand and bubble size requirements between upstream and downstream areas, shallow and deep water areas, and still and turbulent water areas. At the same time, dissolved oxygen saturation and microbial activity vary greatly under the conditions of high summer temperatures and low winter temperatures. Aeration discs with fixed vent sizes cannot meet the needs of these variable environments, often leading to energy waste, prolonged restoration cycles, or poor results. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, the present invention provides a river ecological restoration device to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a river ecological restoration device, comprising a bottom plate installed on the riverbed and multiple air inlet pipes installed on the bottom plate, wherein the multiple air inlet pipes are installed on an external air intake device; further comprising an adjustment mechanism, wherein the adjustment mechanism comprises an aeration plate connected to the air inlet pipes, wherein a deformable plate and a control plate are fitted together on the aeration plate, wherein the deformable plate has multiple air outlets, and the control plate has multiple control pipes corresponding to the air outlets, wherein multiple elastic plates are installed at equal intervals in each air outlet, and each elastic plate has a central hole, wherein the control pipe rests on the elastic plate; further comprising a one-way mechanism, wherein the one-way mechanism comprises a one-way platform installed between the aeration plate and the air inlet pipes, wherein a cone block is fitted together on the one-way platform.

[0008] Preferably, multiple side strips are installed at equal intervals on the side walls of the deformation disc and the control disc, and multiple side grooves are opened at equal intervals on the side wall of the aeration disc. The multiple side strips are slidably connected in the side grooves. This sliding connection structure ensures that the deformation disc and the control disc can move and adjust freely in the vertical direction while maintaining stable alignment in the horizontal direction, preventing offset. This makes the precise adjustment of the air holes more reliable, and also facilitates the installation, disassembly and maintenance of the overall structure.

[0009] Preferably, reinforcing rings are installed on both sides of the control disc, and multiple control tubes are respectively located within the reinforcing rings. A threaded ring is installed on the internal thread of the aeration disc, and the threaded ring presses on the deformable disc. The control disc and the threaded ring do not contact each other. This design enhances the structural strength of the control disc through the reinforcing rings, preventing deformation during long-term use. At the same time, the pressing and fixing of the deformable disc by the threaded ring ensures that the deformable disc is stably installed on the aeration disc. The fact that the control disc does not contact the threaded ring ensures that the control disc can be moved up and down independently for adjustment.

[0010] Preferably, a coarse adjustment sleeve is coaxially mounted on the control panel, and a fine adjustment sleeve is coaxially mounted on the deformable disc. The fine adjustment sleeve is slidably connected inside the coarse adjustment sleeve, and the coarse adjustment sleeve is fixedly connected to the reinforcing ring. This coaxial coarse and fine adjustment sleeve structure design ensures the concentricity of the adjustment mechanism, ensuring that the control panel and the deformable disc maintain a good coaxial alignment during the adjustment process, avoiding uneven adjustment problems caused by eccentricity. At the same time, the sliding connection of the fine adjustment sleeve inside the coarse adjustment sleeve provides stable guidance.

[0011] Preferably, the coarse adjustment sleeve is internally threaded with a coarse adjustment rod, and a fine adjustment rod is installed on the coarse adjustment rod. The fine adjustment rod is threaded into the fine adjustment sleeve. The coarse adjustment rod and the fine adjustment rod are arranged in the same direction, and the pitch of the coarse adjustment rod is slightly larger than that of the fine adjustment rod. A hexagonal rod is installed on the coarse adjustment rod. This dual-threaded adjustment mechanism with the same direction but different pitches cleverly utilizes the principle of pitch difference. The distance adjusted by each rotation is the difference between the two pitches, achieving micron-level precise adjustment capability. This allows the operator to precisely control the position of the control disc through the hexagonal rod, thereby accurately adjusting the size of the air outlet to meet the aeration requirements under different water quality conditions.

[0012] Preferably, bottom tubes are installed at equal intervals inside the aeration disc, and multiple top tubes corresponding to the bottom tubes are installed on the deformation disc. The top tubes are inserted into the bottom tubes, and fixing bolts are threaded into the bottom tubes. The fixing bolts press against the top tubes. Limiting rods and springs are installed on the deformation disc. This insert-type connection combined with the fixing bolts provides secondary fixing protection for the deformation disc, enhancing the stability of the overall structure. At the same time, the setting of the limiting rods and springs not only controls the maximum displacement of the cone block, but also provides a reliable restoring force for the one-way mechanism, ensuring that the device can quickly and effectively achieve sealing when it stops working.

[0013] Preferably, the one-way mechanism includes elastic plates symmetrically installed inside the air intake pipe, an internal rod installed on the cone block, the internal rod and the air intake pipe being coaxially arranged, and locking blocks symmetrically installed on both sides of the internal rod, with the elastic plate attached to the locking blocks. This symmetrical design of the elastic plate and locking block structure ensures the stability and balance of the cone block's movement, avoiding offset and jamming.

[0014] Preferably, the upper and lower ends of the two card blocks are respectively provided with a gentle slope groove and a steep slope groove. When the elastic force of the elastic plate on the steep slope groove is greater than the elastic force of the elastic plate on the gentle slope groove, this ingenious design of the gentle slope and steep slope structure creates an elastic force difference.

[0015] Preferably, two guide rods are installed on the side wall of the internal rod, and a guide groove is provided on the inner wall of the air intake pipe. The guide rods are slidably connected in the guide groove. This sliding connection structure between the guide rods and the guide groove ensures that the cone and the internal rod can only move along the central axis of the air intake pipe, effectively preventing offset and rotation, ensuring that the cone can accurately align and seal with the one-way stage every time, and improving the reliability and service life of the one-way mechanism.

[0016] Preferably, guide sleeves are installed on the two guide rods, and the guide sleeves are slidably connected inside the intake pipe. By adding the guide sleeve structure, the guiding stability is further enhanced. The sliding contact area between the guide sleeve and the inner wall of the intake pipe is larger, reducing wear and providing a better coaxial guiding effect, making the opening and closing movement of the cone block more stable and reliable.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a river water ecological restoration device, which has the following beneficial effects:

[0019] This river ecological restoration device solves the technical pain point of traditional aeration discs being unable to adjust bubble size according to environmental changes through an innovative adjustable aeration system. The device employs a combination of a deformable disc and a control disc, along with an elastic plate and a central hole design, allowing for precise adjustment of the aeration orifice diameter according to actual needs. This design significantly improves oxygen transfer efficiency, enabling the device to adapt to different aquatic environments, water quality conditions, and seasonal changes, thereby greatly enhancing the effectiveness of river ecological restoration. The device utilizes a dual adjustment mechanism combining coarse and fine adjustments. Through the coordinated work of coarse and fine adjustment rods with different pitches but in the same direction, precise adjustment is achieved. This design leverages the principle of pitch difference; the distance moved up and down with each rotation is the difference in pitch between the two rods, thus improving adjustment accuracy. This allows operators to precisely control bubble size according to the specific needs of the water body, achieving optimal aeration results.

[0020] This device features a one-way sealing mechanism. Through the cooperation of the cone block and the one-way platform, along with the design of the elastic plate, gentle slope trough, and steep slope trough, it achieves one-way airflow and reliable sealing. When the device stops working, the combined force of the spring and the elastic plate ensures that the cone block fits tightly against the one-way platform, preventing river water backflow and sludge blockage. When the device starts, the air pressure overcomes the sealing elasticity, causing the cone block to open. At the same time, the different angles of the gentle slope trough and steep slope trough reduce the resistance of airflow and improve energy efficiency. This one-way sealing mechanism significantly extends the service life of the equipment, reduces maintenance frequency, and lowers energy consumption. During long-term operation, even in the event of changes in river water level or temporary shutdown, it can maintain the system's sealing and safety, avoiding the failures and damage caused by poor sealing in traditional aeration systems.

[0021] In summary, this river ecological restoration device improves the efficiency and effectiveness of river ecological restoration through a precisely adjustable aeration system, providing an innovative and practical technical solution for addressing water pollution problems.

[0037] Please see Figures 1 to 11 A river ecological restoration device includes a bottom plate 11 installed on the riverbed and multiple air inlet pipes 12 installed on the bottom plate 11, the multiple air inlet pipes 12 being installed on an external air intake device; it also includes an adjustment mechanism, the adjustment mechanism including an aeration plate 21 connected to the air inlet pipes 12, a deformable plate 22 and a control plate 23 attached to the aeration plate 21, the deformable plate 22 having multiple air outlets 24, and the control plate 23 having multiple control pipes 25 corresponding to the air outlets 24, each air outlet 24 having equal spacing. Multiple elastic plates 26 are installed, each with a central hole 27. Control tubes 25 rest on the elastic plates 26. Multiple side strips 28 are evenly spaced on the side walls of the deformation disc 22 and control disc 23. Multiple side grooves 29 are evenly spaced on the side wall of the aeration disc 21, with the side strips 28 slidably connected within the side grooves 29. Reinforcing rings 210 are installed on both sides of the control disc 23, with the multiple control tubes 25 located within the reinforcing rings 210. Threaded rings 21 are threaded into the aeration disc 21. 1. A threaded ring 211 presses against a deformable disc 22, and the control disc 23 and the threaded ring 211 do not contact each other. A coarse adjusting sleeve 212 is coaxially mounted on the control disc 23, and a fine adjusting sleeve 213 is coaxially mounted on the deformable disc 22. The fine adjusting sleeve 213 is slidably connected inside the coarse adjusting sleeve 212. The coarse adjusting sleeve 212 is fixedly connected to the reinforcing ring 210. A coarse adjusting rod 214 is threadedly connected inside the coarse adjusting sleeve 212. A fine adjusting rod 215 is mounted on the coarse adjusting rod 214. The fine adjusting rod 215 is threadedly connected inside the fine adjusting sleeve 213. The coarse adjusting rod 214 and the fine adjusting rod 215 are connected to the fine adjusting sleeve 213. The adjusting rods 215 are set in the same direction, and the pitch of the coarse adjusting rod 214 is slightly larger than that of the fine adjusting rod 215. A hexagonal rod 216 is installed on the coarse adjusting rod 214. Bottom tubes 217 are installed at equal intervals inside the aeration disc 21. Multiple top tubes 218 corresponding to the bottom tubes 217 are installed on the deformation disc 22. The top tubes 218 are inserted into the bottom tubes 217. A fixing bolt 219 is installed in the thread of the bottom tube 217. The fixing bolt 219 presses on the top tube 218. A limit rod 220 and a spring 221 are installed on the deformation disc 22.

[0038] Before aeration, adjust the size of the air outlet 24 according to different situations. First, adjust the hexagonal rod 216 with a wrench. Since the coarse adjustment rod 214 is threaded onto the coarse adjustment sleeve 212, and the fine adjustment rod 215 is threaded onto the fine adjustment sleeve 213, and the coarse and fine adjustment rods 214 and 215 are set in the same direction, and the pitch of the coarse adjustment rod 214 is greater than the pitch of the fine adjustment rod 215, the vertical movement distance with each rotation is the difference between the pitch of the coarse adjustment rod 214 and the pitch of the fine adjustment rod 215, thus increasing the adjustment range. The precision is achieved by adjusting the control disc 23, which moves up and down. Multiple control tubes 25 move with the control disc 23, and then the multiple control tubes 25 press against the elastic plate 26. When the control tubes 25 move downward, the elastic plate 26 is opened, and the equivalent diameter of the air outlet 24 increases, thus adjusting the aeration bubble effect. When they move upward, the equivalent diameter decreases. Because the control tubes 25 press against the elastic plate 26, the position of the multiple elastic plates 26 is limited, thus completing the adjustment process.

[0039] The one-way mechanism includes a one-way platform 31 installed between the aeration disc 21 and the air inlet pipe 12. A cone block 32 is fitted onto the one-way platform 31. The one-way mechanism includes an elastic plate 33 symmetrically installed inside the air inlet pipe 12. An internal rod 34 is installed on the cone block 32. The internal rod 34 and the air inlet pipe 12 are coaxially arranged. A locking block 35 is symmetrically installed on both sides of the internal rod 34. The elastic plate 33 is fitted onto the locking block 35. The upper and lower ends of the two locking blocks 35 are respectively provided with a gentle slope groove 36 and a steep slope groove 37. When the elastic force of the elastic plate 33 against the steep slope groove 37 is greater than the elastic force of the elastic plate 33 against the gentle slope groove 36, two guide rods 38 are installed on the side wall of the internal rod 34. A guide groove 39 is provided on the inner wall of the air inlet pipe 12. The guide rods 38 are slidably connected in the guide groove 39. Guide sleeves 310 are installed on the two guide rods 38. The guide sleeves 310 are slidably connected in the air inlet pipe 12.

[0040] After the aperture adjustment is completed, oxygen is introduced through the air inlet pipe 12. Due to the pressure, the cone block 32 is pushed open, and the pressure is greater than the elastic force of spring 221 and elastic plate 33. When the cone block 32 is attached to the one-way table 31, the elastic plate 33 is stuck in the ramp groove 36. At this time, the air pressure is greater than the sum of the elastic force of spring 221 and the elastic force of elastic plate 33 in the ramp groove 36. Then the cone block 32 moves upward until it hits the limit rod 220, and at this time, spring 221 is at its maximum deformation. When the pressure is high, the elastic force is slightly greater than that of the elastic plate 33 at the position of the steep slope groove 37. Therefore, when the cone block 32 is opened, it will only have a small impact on the air pressure. When the cone block 32 is closed, the spring 221 and the elastic plate 33 work together to ensure the sealing effect. The one-way setting of the cone block 32 will ensure one-way sealing, thus ensuring the sealing effect when no air is released. After the oxygen is released, the aeration process is carried out through the air outlet 24, thereby completing the ecological restoration process.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
