Description

Technical Field

[0001] The present invention relates to the technical field of aerators, and more particularly to an underwater aeration assembly of an aerator. Background Art

[0002] Impeller aerator is one of the indispensable equipment in existing aquaculture and water management, especially in small and medium-sized ponds and fish farms. In these environments, the dissolved oxygen content of water is directly related to the health and growth of fish and other aquatic organisms. Because the impeller aerator has a simple structure, easy operation and low cost, it can generate strong water flow and bubbles through the high-speed rotation of the impeller, effectively increasing the dissolved oxygen content on the water surface.

[0003] In actual use, it is often difficult to completely solve water quality problems by relying solely on physical oxygenation methods such as aerators, especially in high-density aquaculture or poor water quality environments. In order to further enhance the oxygenation effect and improve water quality, the application of underwater oxygenation assemblies with adsorption agents has gradually become an effective auxiliary means. Through the adsorption of microorganisms by purification agents, the decomposition of organic matter in the water is promoted, and the accumulation of harmful substances is reduced, thereby indirectly improving the self-purification capacity of the water and the dissolved oxygen content.

[0004] However, in high-density fish ponds or shrimp ponds, on the one hand, due to the large amount of organic waste in the water, the water quality deteriorates rapidly, increasing the difficulty of water quality management. On the other hand, the negative pressure end of the aerator has a large water flow rate, which makes the configured adsorbents consume quickly and need to be replenished frequently, increasing maintenance costs and workload. In addition, impeller aerators are usually fixed-point aeration equipment. Once put into use, it is difficult to readjust the position, which makes the replenishment of adsorbents not only impossible to carry out in time, but also time-consuming and labor-intensive.

At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are listed as the best and preferred embodiments, and other alternatives can also be used by technicians in some known technical fields; and the accompanying drawings are only for more specific description of the embodiments, and are not intended to specifically limit the present invention.

[0025] like Figures 1 to 7As shown, an embodiment of the present invention provides an underwater oxygenation assembly of an aerator, comprising a servo motor 1, a rotating rod 2 is fixedly connected to the bottom output end of the servo motor 1, an impeller 3 is fixedly connected to the bottom of the rotating rod 2, a plurality of groups of bulking mechanisms 5 are sequentially arranged on the outer surface of the servo motor 1, an oxygenation agent self-replenishing mechanism 4 for supplying the bulking mechanism 5 on each side is arranged on the upper surface of the servo motor 1, and a linkage mechanism 7 connecting the bulking mechanism 5 on each side and the oxygenation agent self-replenishing mechanism 4 is arranged on the side of the rotating rod 2; The oxygenating agent self-replenishing mechanism 4 includes a conical material collection bin 41 and a discharge cylinder 45 movably arranged on the upper side of the conical material collection bin 41, a powder leakage bottom plate 46 for placing the activated carbon column is fixedly installed on the upper surface of the conical material collection bin 41, and two groups of scrapers 411 attached to the outer surface of the activated carbon column are arranged on the inner wall of the discharge cylinder 45, and the bulking mechanism 5 includes a square protruding cavity sleeve 51; Among them, a plurality of first feeding ducts 42 corresponding to the square protruding cavity sleeves 51 are fixedly connected to the bottom of the conical collecting bin 41, and the output end of the linkage mechanism 7 drives the scraper 411 on the inner wall of the discharge cylinder 45 to rotate around the activated carbon column, so that the carbon powder passes through the powder leakage bottom plate 46 and cooperates with the first feeding duct 42 on each side to be sent to the bulk material mechanism 5 and the impeller 3 to mix with water for automatic underwater oxygenation.

[0026] In order to solve the problems of rapid water quality deterioration, difficulty in consuming and replenishing adsorbents in existing high-density fish ponds or shrimp ponds, which lead to increased maintenance costs and workload, the above technical solution is now adopted. The above technical solution mainly consists of a servo motor 1, a rotating rod 2, an impeller 3, an oxygenation agent self-replenishing mechanism 4, a bulk material mechanism 5 and a linkage mechanism 7. The servo motor 1, the rotating rod 2 and the impeller 3 are inherent accessories of a conventional impeller aerator in the prior art. The impeller 3 on the output end is driven by the servo motor 1 to rotate, forming an oxygenation agent on the water surface. The vortex is formed to promote the contact between air and water, thereby increasing the oxygen content in the water, and the configured oxygenation reagent self-replenishing mechanism 4, the bulking mechanism 5 and the linkage mechanism 7 are a linkage underwater oxygenation assembly system integrated on the aerator, which uses the rotating rod 2 at the output end of the servo motor 1 as the output end, so that the configured linkage mechanism 7 controls the oxygenation reagent self-replenishing mechanism 4 to rotate synchronously to automatically prepare the materials of the oxygenation reagent, and controls the bulking mechanism 5 on the outside to sprinkle the prepared oxygenation reagent into the water and the vortex end of the impeller 3 to perform underwater oxygenation; The oxygenation reagent self-replenishing mechanism 4 includes a conical material collection bin 41 and a discharge cylinder 45 movably arranged on the upper side of the conical material collection bin 41. The upper discharge cylinder 45 is controlled by the linkage mechanism 7 to rotate 360 ​​degrees, and a powder leakage bottom plate 46 is fixedly installed on the upper surface of the conical material collection bin 41. The powder leakage bottom plate 46 is used to place the activated carbon column. The scrapers 411 on both sides of the inner side are scraped around the activated carbon column through the 360-degree rotation of the discharge cylinder 45, and the carbon powder is leaked out through the leakage of the powder leakage bottom plate 46, and the first feeding conduit 42 on the corresponding side is used to send the carbon powder to the bulking mechanism 5 and the impeller 3 to mix with water, so as to perform automatic underwater oxygenation; Among them, the activated carbon column is a cylindrical structure composed of activated carbon in the prior art. Mixing with water to form an activated carbon solution can not only remove harmful substances in the water, but also significantly improve the water quality, enhance the transparency and sensory quality of the water body. In the vortex center of the impeller 3, the water flow speed is faster, forming a negative pressure zone, where bubbles and water flow are most concentrated. Introducing the activated carbon solution into the vortex center can make the activated carbon quickly contact with harmful substances in the water, fully utilizing its adsorption capacity, and due to the strong turbulence in the vortex center, the activated carbon solution can quickly diffuse into the entire water body, ensuring that the adsorbent and pollutants are fully mixed, improving the adsorption efficiency, helping to break the stratification of the water body, preventing the upper water body from being oxygen-rich and the lower water body from being oxygen-deficient, and ensuring that the dissolved oxygen content of the entire water body remains balanced.

[0027] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the impeller 3 is an inverted open-top frustum cover structure as a whole, and a plurality of water-permeable leakage holes are provided on the outer edge surface, a circular wing plate 43 is fixedly installed at the outer edge position of the powder leakage bottom plate 46, and two groups of telescopic pull rods 413 180° apart are fixedly connected to the bottom of the outer edge of the discharge cylinder 45, and the bottoms of the telescopic pull rods 413 are fixedly connected to the limiting clamping plates 414, and the telescopic pull rods 413 and the limiting clamping plates 414 on each side form an L-shaped pull plate structure, and the discharge cylinder 45 is movably clamped on the upper side of the circular wing plate 43 through the structure composed of the telescopic pull rods 413 and the limiting clamping plates 414 on both sides, and the bottom of the discharge cylinder 45 is in an open state, and two reserved openings 47 180° apart are provided on the outer edge surface of the discharge cylinder 45.

[0028] The outer surface of the impeller 3 is also provided with inclined blades with holes. When the servo motor 1 drives the impeller 3 to rotate at high speed, the blades cut the water surface, generating strong water flow and bubbles. The bubbles bring air into the water through the rising process, increasing the dissolved oxygen content of the water body. The telescopic rod 413 is a straight up and down rod structure in the prior art, which is controlled by the internal spring so that the telescopic rod 413 is always in a tightened state, so as to cooperate with the L-shaped pull plate composed of the limit card plate 414 to flexibly cover the discharge cylinder 45 on the upper side of the annular wing plate 43 of the conical collection bin 41.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the interior of the reserved opening 47 is fixedly connected with a U-shaped extension frame 48 extending toward the outer edge of the discharge cylinder 45, and the interior of the U-shaped extension frame 48 is fixedly installed with a first servo telescopic rod 49, and the output end of the first servo telescopic rod 49 is facing the center side of the discharge cylinder 45, and a push plate 410 is fixedly installed on one side of the output end, a scraper 411 is fixedly installed on the push plate 410, and a charged module 412 is fixedly installed on the side of each push plate 410, and an outward-turned sealing cover 415 is movably hinged on the upper side of the discharge cylinder 45, and an alarm module 416 is fixedly installed on the upper surface of the outward-turned sealing cover 415, and the alarm module 416 is connected to the charged modules 412 on both sides through wires.

[0030] Among them, the first servo telescopic rod 49 is an electric telescopic rod structure capable of servo control in the prior art, which is used to control the scraper 411 of the push plate 410 at the output end to fit the activated carbon column on the upper surface of the powder leakage bottom plate 46. Further, the first servo telescopic rod 49 can also be replaced with a spring telescopic rod structure, and the reset characteristics of the spring are used to make the scraper 411 of the push plate 410 fit the activated carbon column on the upper surface of the powder leakage bottom plate 46, and the charged modules 412 on both sides are contact-type power-on structures in the prior art. The working principle is that in a non-contact state, that is, the scrapers 411 on both sides are in a non-contact state, and the circuit is disconnected, so the entire system is not powered and will not trigger an alarm. When the scrapers 411 on both sides are in contact, the circuit will be closed, so that the current can pass, thereby triggering the alarm module 416 alarm mechanism, prompting the maintenance personnel to replenish the materials.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, a plurality of spring cams 417 arranged in a circle are fixedly mounted on the bottom circular edge of the discharge cylinder 45, and the cam end of each spring cam 417 is hemispherical, and a notch ring 44 is fixedly mounted on the upper surface of the circular wing plate 43, the notches on the notch ring 44 correspond one-to-one to the spring cams 417, and each notch side edge on the notch ring 44 is a smooth rounded edge.

[0032] The spring convex buckle 417 and the notch ring 44 are configured to work in an upper and lower fitting manner, and the working principle is as follows: because the discharge cylinder 45 is movably sleeved on the upper side of the conical aggregate bin 41 through the telescopic pull rods 413 and the limit clamping plate 414 on both sides, the discharge cylinder 45 can perform a 360-degree servo rotation on the upper surface of the conical aggregate bin 41 under the action of the drive, and the spring convex buckle 417 and the notch ring 44 are configured between the discharge cylinder 45 and the conical aggregate bin 41, so that the discharge cylinder 45 can perform a 360-degree servo rotation on the upper surface of the conical aggregate bin 41. During the process, the spring convex buckle 417 reciprocates into the notch of the notch ring 44, causing the discharge cylinder 45 to rotate and shake up and down, so that the carbon powder scraped off by the scraper 411 can leak out to the bottom more smoothly through the powder leakage bottom plate 46. Therefore, in order to ensure the stable rotation and shaking up and down, the movable sleeve ends on both sides are retractable movable sleeves composed of a telescopic pull rod 413 and a limit card plate 414, and each notch side is set to a smooth rounded edge to enable the spring convex buckle 417 to move in and out better during the rotation process.

[0033] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the linkage mechanism 7 includes a second auxiliary sleeve 71 fixedly mounted on the side of the servo motor 1, a linkage rotating rod 72 is movably mounted on the protruding end of the second auxiliary sleeve 71, a second gear plate 73 is fixedly mounted on the upper side of the linkage rotating rod 72, and a gear ring 77 is fixedly connected to the outer side of the U-shaped extension frame 48, and the outer side edge of the gear ring 77 is meshed with the second gear plate 73.

[0034] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7As shown, the linkage mechanism 7 also includes a second servo telescopic rod 74 fixedly connected to the bottom of the linkage rotating rod 72, and a third gear plate 75 is fixedly installed on the output end of the second servo telescopic rod 74, and a fourth gear plate 76 is fixedly installed on the outer surface of the rotating rod 2. When the second servo telescopic rod 74 is in a fully extended state, the third gear plate 75 is flush with the side edge of the fourth gear plate 76 and meshes with it.

[0035] Among them, the working principle of the configured linkage mechanism 7 is: First, in the actual working process, the oxygenator does not always need to perform additional underwater oxygenation operation, but only needs to perform underwater oxygenation under special circumstances or at special times, so the oxygenation reagent self-replenishing mechanism 4 is designed to be a closable linkage type. When the existing oxygenation reagent self-replenishing mechanism 4 is working, the second servo telescopic rod 74 in the contracted state extends outward, so that the third gear plate 75 at the output end of the second servo telescopic rod 74 is sleeved on the outer side of the fourth gear plate 76 at the end of the rotating rod 2, so that the third gear plate 75 and the fourth gear plate 76 are meshed and corresponding. In the meshing state, the servo motor 1 drives the rotating rod 2 to drive the impeller 3 to work, and also drives the linkage mechanism 7 to work through the fourth gear plate 76. The specific transmission sequence is: the rotation of the fourth gear plate 76 drives the rotation of the third gear plate 75, and the rotation of the third gear plate 75 causes the linkage rotating rod 72 to rotate, so that the second gear plate 73 drives the meshing gear ring 77 to rotate, and once the gear ring 77 rotates, the entire discharge cylinder 45 can be controlled to rotate on the upper surface of the conical collection bin 41 to perform scraping work. If the oxygen-enhancing reagent does not need to work at one end of the self-replenishing mechanism 4, it is only necessary to retract the third gear plate 75 through the second servo telescopic rod 74. In order to ensure the smooth degree of engagement of the third gear plate 75 and the fourth gear plate 76 on each side, the side edges of the tooth openings of the fourth gear plate 76 and the third gear plate 75 are set to a smooth rounded structure, and the rotation state of the fourth gear plate 76 can be controlled by the servo motor 1 to ensure the smooth engagement of the meshing end.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the bulk material mechanism 5 also includes a first auxiliary sleeve frame 58 fixedly mounted inside the square protruding cavity sleeve 51 near the side of the servo motor 1, and a second bevel gear 59 is movably mounted on the first auxiliary sleeve frame 58, and the bottom of the second bevel gear 59 is fixedly connected to an outward extension rod 510 passing through the square protruding cavity sleeve 51, and the protruding end is fixedly connected to a first gear plate 514 corresponding to the fourth gear plate 76 meshing.

[0037] The configured bulking mechanism 5 as a whole replaces the support structure of the original aerator, so that the device can float on the water surface stably in cooperation with the outer floating ball sleeve 6.

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, the bulk material mechanism 5 also includes a sleeve bracket 52 fixedly connected to the upper side position of the first auxiliary sleeve frame 58, and the sleeve bracket 52 is movably mounted with a first bevel gear 54 meshing with the second bevel gear 59, the surface of the first bevel gear 54 is fixedly connected with a bidirectional threaded rod 53 flush with the protruding end of the square protruding cavity sleeve 51, and the bidirectional threaded rod 53 is meshingly mounted with a scraper 55 slidingly sleeved on the inner side of the square protruding cavity sleeve 51, and the upper side of the scraper 55 is fixedly mounted with a first material temporary storage bin 56, and the side of the first feeding conduit 42 away from the conical collecting bin 41 extends into the interior of the square protruding cavity sleeve 51, and the extended end is aligned with the upper side of the first material temporary storage bin 56 in the state of fitting the sleeve bracket 52.

[0039] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a plurality of reserved leakage holes 511 are provided at the bottom of the square extended cavity sleeve 51, and a second material temporary storage bin 512 is fixedly installed on one side of the bottom of the square extended cavity sleeve 51 close to the extended support rod 510, and the second material temporary storage bin 512 is communicated with the bottom of the square extended cavity sleeve 51 through the reserved leakage holes 511, and a second feeding conduit 513 is fixedly connected to the bottom of the second material temporary storage bin 512, and the extended end of the second feeding conduit 513 faces the upper side of the impeller 3.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 As shown, a narrow-mouthed discharge pipe 57 is fixedly installed at the bottom of the first material temporary storage bin 56 , and a floating ball sleeve 6 is fixedly installed at the outer end of the square outwardly extending cavity sleeve 51 .

[0041] The working principle of the configured bulk material mechanism 5 is as follows: First, through the linkage control of the linkage mechanism 7, after the oxygen enrichment reagent self-replenishing mechanism 4 is driven to work, a large amount of activated carbon powder is generated inside the conical collecting bin 41, and the generated carbon powder is transported outward through the first feeding conduit 42 at the bottom. Since the outer end of the first feeding conduit 42 is connected to the square protruding cavity sleeve 51, the carbon powder is transported from top to bottom to the inside of the square protruding cavity sleeve 51; Then, since the first gear plate 514 on each side is meshed with the fourth gear plate 76, during the rotation of the fourth gear plate 76, the second bevel gear 59 on the upper side of the outrigger rod 510 drives the first bevel gear 54 to rotate, so that the first bevel gear 54 controls the bidirectional threaded rod 53 to rotate, so that the scraper 55 meshed on the outer side of the sleeve bracket 52 moves back and forth along the inner cavity of the square outrigger cavity sleeve 51, pushing the incoming carbon powder back and forth, so that it passes through the reserved leakage hole 511 at the bottom of the square outrigger cavity sleeve 51; Among them, most of the carbon powder will be scattered on the water surface through the reserved leak hole 511 under the action of the scraper 55, and a part of the carbon powder will enter the second material temporary storage bin 512 through the reserved leak hole 511. Since the second material temporary storage bin 512 is an inverted trapezoidal cavity structure that gradually becomes smaller from top to bottom, the entered powder will gather at the bottom and then be transported to the upper side of the impeller 3, that is, to the center of the vortex, by the second feeding conduit 513. It is quickly mixed with the vortex, and the powder scattered on the water surface outside will also be scattered to directly increase the mixing area. Furthermore, in order to ensure that activated carbon powder can fall at every position along the bottom of the square protruding cavity sleeve 51 when the scraper 55 is moving, that is, to ensure the degree of dispersion of the powder, a first material temporary storage bin 56 is also provided on the scraper 55. When the scraper 55 is in a state of being fitted with the bracket 52, the powder transported to the inside of the square protruding cavity sleeve 51 through the first feeding conduit 42 will enter the first material temporary storage bin 56, and the narrow-mouthed discharge pipe 57 at the bottom of the first material temporary storage bin 56 will extend the speed of powder leakage, so that more powder will be sent to the outer end of the square protruding cavity sleeve 51, thereby increasing the diffusion area of ​​the powder reagent as much as possible.
