Description

Technical Field

[0001] This invention relates to the field of water quality ecological restoration technology, specifically to a water quality ecological restoration device for hydraulic engineering and environmental applications. Background Technology

[0002] Water quality ecological restoration in water engineering and environmental protection mainly includes microbial restoration, biological restoration, physical restoration, chemical restoration, and comprehensive ecological engineering measures. Aerators are an important component of sewage treatment equipment. By injecting air into sewage, they enhance the contact between organic matter, microorganisms, and dissolved oxygen in the sewage, promote aerobic respiration of microorganisms to decompose organic matter in the sewage tank, making it inorganic, thereby achieving the purpose of purifying water quality.

[0003] For example, CN222476357U proposes an aerator. A filter assembly is installed at the water inlet at the lower end of the aerator body. A cutting assembly is located directly below the filter assembly. Drive components are installed on both sides of the cutting assembly to drive the cutting assembly to move up and down. The drive components move the cutting assembly closer to the filter assembly, causing the cutting assembly to cut flexible impurities on the surface of the filter assembly. Through the filter plate with a blade surface set at the water inlet, and the conical block and mounting plate set at the lower end of the filter plate, the water in the pool is filtered before entering the aerator. The mounting plate, together with the blade surface of the filter plate, cuts the flexible impurities, forming small impurities that do not clog the aerator, thus enabling the aerator to operate normally and avoiding the direct entry of larger flexible impurities into the aerator body. The method of cutting without rotating the blade also avoids the problem of flexible impurities getting entangled on the blade and causing damage to the machine.

[0004] Currently, aerators have limited coverage during aeration, necessitating their relocation to expand the aeration range. However, this relocation prevents simultaneous aeration of water at different depths, hindering the purification of water at varying levels. Furthermore, the operation of aerators requires turning over the sediment at the bottom to prevent it from becoming stagnant and losing oxygen, which is detrimental to water quality remediation. Existing aerators cannot achieve this. Moreover, some sediment has been deposited for a long time and has low oxygen content; even with turning over, the amount of oxygen it can absorb is limited, further hindering water quality remediation.

[0005] To address the above issues, a water quality ecological restoration device for water engineering and environmental protection is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a water quality ecological restoration device for water bodies in water engineering and environmental protection. By using this device, the problems mentioned above can be solved, namely, the inability to simultaneously aerate water bodies at different depths and achieve the effect of simultaneous purification at different water levels. In addition, existing aerators cannot turn over the deposited soil during use, and some soil has been deposited for a long time and has a low oxygen content. Even if the soil is turned over, the amount of oxygen it can absorb is still very small.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a water quality ecological restoration device for hydraulic engineering and environmental regeneration, comprising a shell, an air supply layer inside the shell, an aeration disc rotatably connected to the bottom of the shell, multiple connection holes between the shell and the aeration disc, a motor fixedly connected to the top of the shell, a rotating rod fixedly connected to the output end of the motor, one end of the rotating rod penetrating through the top wall of the shell and fixedly connected to the aeration disc, air guide pipes symmetrically fixedly connected to the top wall of the shell, multiple circular holes equidistantly opened on the side wall of the shell, an auxiliary component slidably installed on the inner wall of the shell, a soil turning component installed on the bottom wall of the aeration disc, and an oxygen supply component installed inside the soil turning component.

[0008] Furthermore, the auxiliary component includes a sleeve that is embedded and slides within the inner wall of the housing. The sleeve has multiple through holes equidistantly opened on its side wall, and the through holes and round holes are arranged alternately. A first permanent magnet is symmetrically fixedly connected to the bottom wall of the sleeve.

[0009] Furthermore, an installation ring is fixedly connected to the inner wall of the housing, and a first electromagnet is symmetrically fixedly connected to the top of the installation ring. The first permanent magnet and the first electromagnet are located in the same plane.

[0010] Furthermore, the soil turning component includes a mounting box, which is fixedly connected to the bottom wall of the aeration disc. The top wall of the mounting box is rotatably connected to a rotating rod, and multiple first locking blocks are fixedly connected at equal angles to the side wall of one end of the rotating rod inside the mounting box.

[0011] Furthermore, a first bevel gear is slidably connected through the side wall of the rotating rod, and a second locking block is fixedly connected at an equal angle to the inner wall of the first bevel gear. The adjacent surfaces of the first locking block and the second locking block are both conical structures. Springs are symmetrically fixedly connected to the top wall of the mounting box, and a telescopic rod is fixedly connected to the top wall of the mounting box. The other end of the telescopic rod is fixedly connected to the top of the first bevel gear, and the spring is sleeved on the outer wall of the telescopic rod.

[0012] Furthermore, each of the springs is fixedly connected to the top of the first bevel gear, a first magnet is fixedly connected to the top wall of the mounting box, a second magnet is fixedly connected to the top wall of the first bevel gear, a second electromagnet is fixedly connected to the top wall of the mounting box, and a second permanent magnet is fixedly connected to the top wall of the first bevel gear.

[0013] Furthermore, hollow tubes are symmetrically and rotatably connected through the sidewalls of the mounting box, and a second bevel gear is fixedly connected to one end of each hollow tube inside the mounting box. Each second bevel gear meshes with a first bevel gear.

[0014] Furthermore, a mounting frame is fixedly connected to the side wall of the mounting box. The mounting frame has a U-shaped structure. A connecting roller is fixedly connected to the side wall of each hollow tube. A connecting shaft is fixedly connected to one end of the connecting roller. The connecting shaft is rotatably connected to the side wall of the adjacent mounting frame. Multiple scrapers are fixedly connected to the side wall of each connecting roller.

[0015] Furthermore, the oxygen delivery assembly includes a cavity, which is opened inside the connecting roller. The two hollow tubes are rotatably and sealed together by a first connecting pipe, and the side wall of the first connecting pipe is fixedly connected to a second connecting pipe.

[0016] Furthermore, a first one-way valve is installed inside the second connecting pipe. One end of the second connecting pipe passes through the side wall of the mounting box and is fixedly connected to the bottom wall of the aeration disc. Multiple exhaust pipes are fixedly connected at equal intervals to the side wall of the cavity, and a second one-way valve is installed inside each exhaust pipe.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up auxiliary components, when aeration is required for water bodies at different levels, the first electromagnet is energized, causing opposite magnetic poles to be generated on the adjacent surfaces of the first electromagnet and the first permanent magnet. The resulting magnetic attraction drives the sleeve downwards. During this movement, the through-holes on the sleeve's sidewall and the circular holes on the shell's sidewall become interconnected, thus connecting the air-transporting layer inside the shell with the water body. Air flows into the water body through the circular holes and through-holes, achieving the purpose of oxygenating the water. By setting multiple through-holes vertically, when the circular holes and through-holes are connected, water bodies at different levels can be aerated simultaneously. Oxygen supply operations are performed to expand the water purification range and improve the effectiveness. By setting up a soil-turning component, when the first bevel gear and the second bevel gear mesh, the second locking block on the inner wall of the first bevel gear will engage with the first locking block on the side wall of the rotating rod, so that the first bevel gear and the rotating rod rotate synchronously, thereby causing the second bevel gear to rotate. This rotation is driven by the hollow tube to rotate the connecting roller and the scraper. The rotating scraper contacts the deposited soil, thereby continuously turning over the deposited soil, loosening the soil, and preventing the soil from becoming dead mud after being deposited for too long, which is not conducive to the growth of microorganisms and affects water quality restoration. By setting up an oxygen supply component, during the soil turning operation, the first and second one-way valves are opened, allowing air inside the aeration disc to enter through the second connecting pipe and then through the first connecting pipe into the cavities of the connecting rollers on both sides. This fills the cavities with gas, which is then discharged through the exhaust pipe. As the connecting rollers rotate, the scraper continuously turns over the deposited soil, providing air to the soil as it rolls. Each time the soil is turned up and falls back down under gravity, it traps the surrounding air, thus replenishing the oxygen inside the deposited soil. This replenishment of oxygen to the soil promotes microbial growth and improves the water quality remediation effect. Attached Figure Description

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] To address the technical challenge of addressing the limitation of aerator coverage during aeration, necessitating the relocation of aerators to expand the aeration range, and the inability of aerators to simultaneously aerate and oxygenate water at different depths during relocation, thus achieving simultaneous purification of water at various levels, the following measures are proposed: Figure 1 - Figure 5 As shown, the following preferred technical solutions are provided: A water quality ecological restoration device for hydraulic engineering and recycling includes a shell 1, with an air supply layer 11 inside the shell 1. An aeration disc 12 is rotatably connected to the bottom of the shell 1, and multiple connection holes 14 are provided between the shell 1 and the aeration disc 12. A motor 2 is fixedly connected to the top of the shell 1, and a rotating rod 21 is fixedly connected to the output end of the motor 2. One end of the rotating rod 21 penetrates through the top wall of the shell 1 and is fixedly connected to the aeration disc 12. Air guide pipes 3 are symmetrically fixedly connected to the top wall of the shell 1, and multiple circular holes 13 are equidistantly provided on the side wall of the shell 1. The working principle of existing aerators is to promote the growth of microorganisms and the degradation of organic matter by increasing the dissolved oxygen content in the water, thereby restoring water quality. Specifically, this is achieved by mechanically agitating the water and delivering air to the water. The device allows for full contact between air and water, increasing the dissolved oxygen content in the water. Sufficient dissolved oxygen promotes the growth and reproduction of aerobic microorganisms, which decompose organic matter in the water, such as residual algae and microbial remains, thereby purifying the water. In use, the aeration disc 12 is placed in the water and driven by the motor 2, which rotates the rotating rod 21 and the aeration disc 12 to agitate the water. An external air pump introduces air into the air delivery layer 11 through the air guide pipe 3. The air then enters the aeration disc 12 through the connecting hole 14 and is finally delivered into the water. The rotation of the aeration disc 12 delivers oxygen, increasing oxygen dissolution and promoting the growth of aerobic organisms, thereby decomposing organic matter in the water and purifying the water.

[0022] An auxiliary component 4 is slidably installed on the inner wall of the shell 1. By setting the auxiliary component 4, when aeration is required for water bodies at different water levels, the first electromagnet 45 is energized, causing the adjacent surfaces of the first electromagnet 45 and the first permanent magnet 43 to generate opposite magnetic poles. The generated magnetic attraction force drives the sleeve 41 to move downward. During the movement, the through hole 42 on the side wall of the sleeve 41 and the round hole 13 on the side wall of the shell 1 will change from an intersecting position to an interconnected position, thereby connecting the air supply layer 11 inside the shell 1 with the water body. Air flows into the water body through the round hole 13 and the through hole 42, achieving the purpose of oxygenation of the water body. By setting multiple through holes 42 in the vertical direction, when the round hole 13 and the through hole 42 are connected, oxygenation can be carried out on water bodies at different water levels at the same time, thereby expanding the water purification range and improving the usage effect.

[0023] A soil-turning component 5 is installed on the bottom wall of the aeration disc 12. By setting the soil-turning component 5, when the first bevel gear 54 and the second bevel gear 510 mesh, the second locking block 59 on the inner wall of the first bevel gear 54 will engage with the first locking block 52 on the side wall of the rotating rod 21, so that the first bevel gear 54 and the rotating rod 21 rotate synchronously, thereby causing the second bevel gear 510 to rotate. This rotation is then driven by the hollow tube 511 to rotate the connecting roller 512 and the scraper 513. The rotating scraper 513 contacts the deposited soil, thereby continuously turning over the deposited soil, loosening the soil, and preventing the soil from becoming dead mud due to prolonged deposition, which is not conducive to the growth of microorganisms and affects water quality restoration.

[0024] An oxygen supply component 6 is installed inside the soil turning component 5. By setting the oxygen supply component 6, during the soil turning operation, the first one-way valve 64 and the second one-way valve 66 are opened, allowing air inside the aeration disc 12 to enter through the second connecting pipe 63 and then through the first connecting pipe 62 into the cavities 61 of the two connecting rollers 512. This fills the cavities 61 with gas, which is then discharged through the exhaust pipe 65. As the connecting rollers 512 rotate, the scraper 513 continuously turns the deposited soil, providing air to the soil turning area. Each time the soil is turned up and falls back down under gravity, it encapsulates the surrounding air, thus replenishing the deposited soil with oxygen. This replenishment of oxygen to the soil promotes microbial growth and improves the water quality remediation effect.

[0025] Auxiliary component 4 includes sleeve 41, which is embedded and slides within the inner wall of housing 1. Multiple through holes 42 are equidistantly opened on the side wall of sleeve 41, and the through holes 42 and round holes 13 are staggered. A first permanent magnet 43 is symmetrically fixedly connected to the bottom wall of sleeve 41.

[0026] A mounting ring 44 is fixedly connected to the inner wall of the housing 1. A first electromagnet 45 is symmetrically fixedly connected to the top of the mounting ring 44. The first permanent magnet 43 and the first electromagnet 45 are located on the same plane.

[0027] In this scheme: when aeration is required for water bodies at different water levels, the first electromagnet 45 is energized, causing the adjacent surfaces of the first electromagnet 45 and the first permanent magnet 43 to generate opposite magnetic poles. The resulting magnetic attraction drives the sleeve 41 to move downward. During the movement, the through hole 42 on the side wall of the sleeve 41 and the circular hole 13 on the side wall of the shell 1 will change from an intersecting position to interconnected, thereby connecting the air supply layer 11 inside the shell 1 with the water body. The oxygen flow rate in the air supply layer 11 is relatively high, which is sufficient to allow air to flow from the circular hole 13 and the through hole 42 into the water body after the circular hole 13 and the through hole 42 are connected, thus achieving the purpose of oxygen supply to the water body. By setting multiple through holes 42 along the vertical direction, when the circular hole 13 and the through hole 42 are connected, oxygen supply can be carried out on water bodies at different water levels at the same time, thereby expanding the water purification range and improving the usage effect. When aeration of water at a certain depth is required, the current flow direction of the first electromagnet 45 is changed by an external current diverter, so that the electromagnetic force between the first electromagnet 45 and the first permanent magnet 43 becomes like magnetic poles. Under the action of magnetic repulsion, the sleeve 41 is pushed upward and reset, so that the round hole 13 and the through hole 42 are crossed again to form a seal, so that only the aeration disc 12 performs aeration. During the movement of the sleeve 41, some water may enter the air delivery layer 11. After the round hole 13 and the through hole 42 are crossed again, under the action of continued air delivery, the water inside the air delivery layer 11 is pushed into the aeration disc 12 through the connecting hole 14 and then discharged again, so as not to have any impact.

[0028] To address the technical challenge of turning over the sediment at the bottom of the aerator during operation to prevent it from becoming stagnant and losing oxygen, thus hindering water quality remediation, existing aerators are currently unable to perform this task. Figure 6 - Figure 9 As shown, the following preferred technical solutions are provided: The soil turning component 5 includes a mounting box 51, which is fixedly connected to the bottom wall of the aeration disc 12. The top wall of the mounting box 51 is rotatably connected to the rotating rod 21. Multiple first locking blocks 52 are fixedly connected at equal angles to one end of the rotating rod 21 inside the mounting box 51.

[0029] A first bevel gear 54 is slidably connected through the side wall of the rotating rod 21. A second locking block 59 is fixedly connected at an equal angle to the inner wall of the first bevel gear 54. The adjacent surfaces of the first locking block 52 and the second locking block 59 are both conical structures. A spring 53 is symmetrically fixedly connected to the top wall of the mounting box 51. A telescopic rod 516 is fixedly connected to the top wall of the mounting box 51. The other end of the telescopic rod 516 is fixedly connected to the top of the first bevel gear 54. The spring 53 is sleeved on the outer wall of the telescopic rod 516.

[0030] Each spring 53 is fixedly connected to the top of the first bevel gear 54. A first magnet 55 is fixedly connected to the top wall of the mounting box 51. A second magnet 56 is fixedly connected to the top wall of the first bevel gear 54. A second electromagnet 57 is fixedly connected to the top wall of the mounting box 51. A second permanent magnet 58 is fixedly connected to the top wall of the first bevel gear 54.

[0031] Hollow tubes 511 are symmetrically and rotatably connected through the side wall of the mounting box 51. Each hollow tube 511 has a second bevel gear 510 fixedly connected to one end of its side wall inside the mounting box 51. Each second bevel gear 510 meshes with a first bevel gear 54.

[0032] Mounting box 51 has a mounting frame 514 fixedly connected to its side wall. The mounting frame 514 has a U-shaped structure. Each hollow tube 511 has a connecting roller 512 fixedly connected to its side wall. One end of the connecting roller 512 is fixedly connected to a connecting shaft 515. The connecting shaft 515 is rotatably connected to the side wall of the adjacent mounting frame 514. Each connecting roller 512 has multiple scrapers 513 fixedly connected to its side wall.

[0033] In this scheme: During the aeration operation, if it is necessary to turn over the bottom sediment, the second electromagnet 57 is energized, causing the second electromagnet 57 and the second permanent magnet 58 to generate like magnetic poles, pushing the first bevel gear 54 downward. This causes the second magnet 56 at the top of the first bevel gear 54 to detach from the first magnet 55, and under the elastic action of the spring 53, push the first bevel gear 54 downward, causing the first bevel gear 54 to mesh with the two second bevel gears 510. In the initial state, the first magnet 55 and the second magnet 56 attract each other, and the spring 53 is in a compressed state. The magnetic attraction force of the first magnet 55 and the second magnet 56 is greater than the sum of the elastic force of the spring 53 and the weight of the first bevel gear 54, thus causing the first bevel gear 54 and the second bevel gear 510 to mesh. The gears 510 do not contact each other, ensuring that the soil turning component 5 can be controlled according to the usage conditions. This avoids the soil turning component 5 working synchronously with the aerator without performing soil turning operations, which would result in energy waste. When the first bevel gear 54 and the second bevel gear 510 mesh, the second locking block 59 on the inner wall of the first bevel gear 54 will engage with the first locking block 52 on the side wall of the rotating rod 21, so that the first bevel gear 54 and the rotating rod 21 rotate synchronously, thereby causing the second bevel gear 510 to rotate. This rotation, through the hollow tube 511, drives the connecting roller 512 and the scraper 513 to rotate. The rotating scraper 513 contacts the deposited soil, thereby continuously turning the deposited soil, loosening the soil, and preventing the soil from becoming dead mud after being deposited for too long, which is not conducive to the growth of microorganisms and affects water quality restoration. When the soil turning operation is completed and the soil turning component 5 is no longer needed, the current flow direction of the second electromagnet 57 is changed by the external current diverter, so that the second electromagnet 57 and the second permanent magnet 58 generate opposite magnetic poles. The generated magnetic attraction force drives the first bevel gear 54 to move upward until the second magnet 56 at the top of the first bevel gear 54 contacts the first magnet 55 and magnetically attracts and fixes the first bevel gear 54. At this time, the first locking block 52 and the second locking block 59 disengage from each other, so that the first bevel gear 54 stops rotating, thereby stopping the connecting roller 512 and the scraper 513 from rotating. The rotating rod 21, the aeration disc 12 and the mounting box 51 rotate synchronously, and the spring 53 is fixed to the inner top wall of the mounting box 51, so that the spring 53 will not have a limit phenomenon.

[0034] To address the technical problem that some soil deposits have been deposited for a long time and have low oxygen content, resulting in limited oxygen absorption even after silt turning, which is detrimental to water quality remediation operations, such as... Figure 6 and Figure 10 As shown, the following preferred technical solutions are provided: The oxygen delivery assembly 6 includes a cavity 61, which is opened inside the connecting roller 512. The two hollow tubes 511 are rotatably connected to a first connecting tube 62, and the side wall of the first connecting tube 62 is fixedly connected to a second connecting tube 63.

[0035] The second connecting pipe 63 is equipped with a first one-way valve 64. One end of the second connecting pipe 63 passes through the side wall of the mounting box 51 and is fixedly connected to the bottom wall of the aeration disc 12. Multiple exhaust pipes 65 are fixedly connected at equal intervals on the side wall of the cavity 61. Each exhaust pipe 65 is equipped with a second one-way valve 66.

[0036] In this scheme: During the soil turning operation, the first one-way valve 64 and the second one-way valve 66 are opened, allowing the air inside the aeration disc 12 to enter through the second connecting pipe 63 and then through the first connecting pipe 62 into the cavity 61 of the connecting rollers 512 on both sides, filling the cavity 61 with gas. The gas is then discharged through the exhaust pipe 65. As the connecting rollers 512 rotate, the scraper 513 continuously turns over the deposited soil, providing air at the soil turning point. Each time the soil is turned over and falls back down under gravity, it carries some air into the soil, thus replenishing the deposited soil with oxygen. This allows the soil to regain oxygen, which is beneficial for microbial growth and improves the water quality remediation effect. After oxygen replenishment is complete, simply close the first one-way valve 64 and the second one-way valve 66 to shut off the oxygen supply. The operation is simple and convenient.
