Description

Technical Field

[0001] This invention relates to the field of water treatment technology, specifically to a water body dynamic structure. Background Technology

[0002] "Living water" refers to water bodies with continuous flow or high molecular activity. Its core value lies in significantly enhancing the self-purification capacity and ecological stability of water bodies through the synergistic effects of physical dynamics, chemical oxidation, and biological metabolism. It refers not only to the physical state of water flow but also emphasizes the optimization of water molecule cluster structure—small molecule clusters have lower surface tension, stronger permeability and dissolving power, and can efficiently promote oxygen transport and nutrient cycling, thereby activating the metabolic potential of the water body. This state can be achieved through natural flow or artificial intervention (such as aeration, water replenishment, and hydraulic circulation).

[0003] In aquaculture water bodies, flowing water is considered a key technological approach to restore the function of the aquatic ecosystem. Through water flow, pollutants are diluted and diffused, sediment resuspension is inhibited, water transparency is improved, and dissolved oxygen (DO) concentration is increased to promote the oxidation of ammonia nitrogen to nitrate and ferrous ions to ferric precipitate, thereby reducing the toxicity of toxic substances and maintaining a dynamic balance of "oxygen consumption-reoxygenation" in the water. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a water body dynamic water structure.

[0005] The technical solution of the present invention is: a water body living water structure, including a floating platform, an ecological filter screen disposed on the floating platform, and a suction assembly disposed below the floating platform; The ecological filter screen consists of a filter screen body and a cleaning disc rotatably mounted on the bottom surface of the filter screen body; the bottom surface of the filter screen body has alternating mesh plate areas and solid plate areas, and the cleaning disc has bristles for cleaning the bottom surface of the filter screen body; The suction assembly consists of multiple suction pipes and a water pump connected to each of the suction pipes for suctioning water. A drive ring is rotatably provided on the filter body located below the suction pipe, and the drive ring is fixed to the cleaning disc by a number of connecting rods arranged at equal intervals. The drive ring has a number of guide holes that are driven by the falling water flow.

[0006] Furthermore, the water pump is fixedly connected to the center of the bottom surface of the filter screen body via a fixing rod, and the suction pipe is a rigid pipe, which is circumferentially arranged on the side of the filter screen body.

[0007] Note: By using rigid tubing as the preferred material for the suction tube, it is possible to avoid fixing the suction tube to the side of the filter body, thus preventing the problem of one-way rotation obstruction when the drive ring drives the cleaning disc to rotate, thereby ensuring the effective operation of the cleaning disc.

[0008] Furthermore, the suction tube is circumferentially arranged on the side of the filter body and fixedly connected to the side of the filter body, and a connecting rod is provided between two adjacent suction tubes.

[0009] Explanation: By connecting the suction tube to the side of the filter body, the vibration problem caused by the excessively long suction tube during water pump operation can be avoided, reducing the impact of vibration on the drive ring. At the same time, in conjunction with the design of components such as the slider, the problem of unidirectional rotation obstruction when the cleaning disc rotates can be effectively avoided, turning unidirectional rotation into reciprocating oscillation. This solves the problem that fixing the suction tube to the side of the filter body would affect the setting of the connecting rod or baffle rod of the drive ring.

[0010] Furthermore, a slider for switching the direction of flow is provided in the flow guide hole located between two adjacent suction tubes. The slider is an arc-shaped block composed of several sub-blocks with an isosceles trapezoidal cross-section. The sub-blocks have symmetrically distributed A-side and B-side, and the slope is 30~45°. The slider is equipped with a set of levers at both ends, which are used to cooperate with the side wall of the suction tube on the corresponding side to switch the slider to face water on side A and side B; and the mesh plate area of ​​the filter body corresponds to the swinging area of ​​the brush bristles.

[0011] Explanation: By setting the slider to be offset, each sub-block can be positioned in the guide hole with either side A or side B facing the water. When the drive ring moves to the end position at both ends, it can trigger the lever on the corresponding side to switch the slider between side A and side B, thereby changing the unidirectional rotation of the drive ring into reciprocating oscillation, effectively avoiding the problem of unidirectional rotation obstruction when the cleaning disc rotates.

[0012] Furthermore, the filter body is planted with water-purifying plants, which are any one or more of water hyacinth, water hyacinth, and duckweed. The ecological floating island is filled with a planting substrate with a thickness of 1-2 cm, which is a mixture of straw and rice husks in a mass ratio of 3-5:2.

[0013] Note: Floating aquatic plants such as water hyacinth, water lettuce, and duckweed play a significant role in water purification, especially in eutrophic or polluted still and slow-flowing water environments. They effectively improve water quality through root absorption, biosorption, and synergistic effects with microorganisms. However, they are not limited to the water-purifying plants listed above. The appropriate plants can be selected based on the actual application and local plant availability. Additionally, by using fibers such as straw and rice husks to absorb particulate matter in the water, the C / N ratio of the water can be increased, thereby enhancing the effect of biofilm in reducing ammonia nitrogen and nitrite nitrogen in the water.

[0014] Furthermore, the filter body contains one or more of diatoms, Chlorella, and Scenedesmus.

[0015] Note: Beneficial algae cultivated through targeted methods efficiently absorb nutrients such as nitrogen and phosphorus from water through photosynthesis, achieving "treatment of pollution with algae," reducing the risk of eutrophication. Furthermore, cultivation at the water surface ensures light penetration, promotes photosynthesis, and avoids anaerobic conditions in deep water. They can form a closed-loop system of "water activation - biological promotion - ecological maintenance" with filter-feeding fish and submerged plants. However, they are not limited to the algae listed above; appropriate selection should be made based on actual usage and local plant conditions.

[0016] Furthermore, the drive ring is provided with a plurality of baffles for agitating the filter body.

[0017] Explanation: By setting up the baffle rod, the structural design of the drive ring can be further utilized to prevent algae settling and light shading, enhance mass transfer efficiency, optimize dissolved oxygen and gas exchange, thereby improving the system stability of algae cultivation and enhancing the water circulation effect.

[0018] Furthermore, the ecological filter screen is equipped with an oxygenation pump, which extends into the water body through an air pipe, and the end of the air pipe is equipped with an air bubble stone.

[0019] Note: By setting up an oxygenation pump, the aeration and oxygenation operations can be increased according to the actual needs of the water body, thereby further improving the effect of water circulation.

[0020] The beneficial effects of this invention are: (1) The present invention, through the combined design of floating platform, ecological filter and suction assembly, can be applied to the treatment of living water in various water bodies, such as the treatment of living water in aquaculture water bodies. By utilizing the water kinetic energy of the suction assembly, the ecological filter can be automatically cleared to ensure that the lower layer water transported by the suction pipe can effectively pass through the biological filter bed composed of straw, rice husks, etc., as well as water purification plants or algae, before flowing back into the water body, thereby improving the living water effect.

[0021] (2) In this invention, under the concept of treating pollution with algae in algae farming, the ecological filter is divided into multiple staggered mesh plate areas and solid plate areas, so that the ecological filter forms a partially circulating mesh structure, thereby increasing the residence time of the lower layer water transported by the suction pipe in the ecological filter. Furthermore, the drive ring and other components have been optimized for this structure, which not only improves the stability of equipment operation, but also makes the brush bristles only scrape the mesh plate area, and effectively solves the problem that fixing the suction pipe to the side of the filter body will affect the setting of the connecting rod or the turbulence rod of the drive ring.

Detailed Implementation

[0023] The present invention will now be described in more detail with reference to specific embodiments, so as to better demonstrate the advantages of the present invention.

[0024] Example 1: As Figure 1As shown, a water body living structure includes a floating platform 1, an ecological filter screen 2 installed on the floating platform 1, and a suction assembly 3 installed below the floating platform 1. like Figure 2 , Figure 6 As shown, the ecological filter 2 consists of a filter body 21 and a cleaning disc 22 rotatably mounted on the bottom surface of the filter body 21. The cleaning disc 22 consists of an inner disc, an outer ring, and a scraper connecting the inner disc and the outer ring. The bottom surface of the filter body 21 has three sets of mesh plate areas 24 and three sets of solid plate areas 25 distributed alternately. The cleaning disc 22 has bristles 23 for cleaning the bottom surface of the filter body 21. Specifically, the bristles 23 are mounted on the scraper. The filter body 21 is planted with water-purifying plants, namely water hyacinth. It should be noted that the plants are not limited to those listed above. They can be selected according to the actual use and the local plant conditions. At the same time, the ecological floating island 3 is filled with a planting substrate with a thickness of 1.5 cm. The planting substrate is a mixture of straw and rice husks in a mass ratio of 2:1. like Figure 2 As shown, the suction assembly 3 consists of three suction pipes 31 and a water pump 32 connected to each suction pipe 31 for suctioning water. It should be noted that the water pump 32 is commercially available. The water pump 32 is fixedly connected to the center of the bottom surface of the filter body 21 by a fixing rod, and the suction pipe 31 is a rigid pipe, which is circumferentially arranged on the side of the filter body 21. like Figure 2 , Figure 7 As shown, a drive ring 4 is rotatably provided on the filter body 21 located below the suction pipe 31. Specifically, an annular support frame is provided on the inner wall of the filter body 21, and an annular groove that slides with the annular support frame is provided on the bottom surface of the drive ring 4. The drive ring 4 is fixed to the cleaning disc 22 by three equally spaced connecting rods 5. The drive ring 4 has several guide holes 41 that are driven by the falling water flow. A guide plate with an inclination of 45° is provided on one side wall of the guide hole 41.

[0025] The working principle of the above-mentioned water body living water structure is as follows: the planting substrate is pre-filled into the filter body 21, and water purification plants such as water hyacinth are planted in the filter body 21. Then, the water pump 32 is started, and the water from the lower layer of the water body is pumped to the filter body 21 through the suction pipe 31. At the same time, with the cooperation of the water outlet of the suction pipe 31 and the drive ring 4, the kinetic energy of the water body is utilized by the guide hole 41, thereby causing the drive ring 4 to rotate. Thus, the drive ring 4 and the cleaning disc 22 are linked to rotate the cleaning disc 22. The brush bristles 23 periodically scrape the mesh plate area 24 to improve the water permeability of the mesh plate area 24.

[0026] Example 2: This example differs from Example 1 in that, as Figure 3 As shown, the filter body 21 is cultured with Chlorella. It should be noted that it is not limited to the algae listed above. The appropriate algae can be selected according to the actual use and the local plant conditions. The suction pipe 31 is arranged circumferentially on the side of the filter body 21 and is fixedly connected to the side of the filter body 21. A connecting rod 5 is provided between two adjacent suction pipes 31. like Figures 8-10 As shown, a slider 6 for switching the flow direction is provided in the guide hole 41 located between two adjacent suction pipes 31. The slider 6 is an arc-shaped block composed of several sub-blocks 61 with an isosceles trapezoidal longitudinal section. The sub-blocks 61 have symmetrically distributed A-side 63 and B-side 64, and the slope of each is 30~45°. A set of levers 62 are provided at both ends of the slider 6, which are used to cooperate with the side wall of the suction pipe 31 on the corresponding side to switch the slider 6 to face the water on A-side 63 and B-side 64. The mesh plate area 24 of the filter body 21 corresponds to the swing area of ​​the brush bristles 23.

[0027] The working principle of the above-mentioned water body active water structure is as follows: The difference from the working principle of Embodiment 1 is that the operation method of the drive ring 4 is changed from unidirectional rotation to reciprocating swing. Through the slider 6 of the drive ring 4, in order to improve the positioning effect of the slider 6, two first magnetic blocks can be set on the inner wall of each area of ​​the drive ring 4 body without the guide hole 4. Their positions correspond to the water-facing positions of the A side 63 and B side 64 of the slider 6, respectively. At the same time, a second magnetic block is provided on the trapezoidal top surface of each sub-block 61 to cooperate with it, thereby improving the switching effect of the A side 63 and B side 64 facing the water. For example, when the A side 63 faces the water, after swinging it to the limit position, under the driving action of the water flow, its lever 62 will push against the suction pipe 31, so that the slider 6 slides to switch to the B side 64. Thus, the slider 6 switches between the A side 63 and the B side 64 in each guide hole 41. In addition, rubber pads can be set on the lever 62 and the suction pipe 31 to reduce the impact.

[0028] Example 3: This example differs from Example 2 in that, as Figure 4 As shown, the drive ring 4 is also provided with three baffle rods 42 for agitating the filter body 21.

[0029] The working principle of the above-mentioned water body living structure is as follows: the difference from the working principle of Example 2 is that during the rotation of the drive ring 4, the turbulence rod 42 is driven to swing synchronously to prevent algae from settling and light from being blocked, enhance mass transfer efficiency, optimize dissolved oxygen and gas exchange, thereby improving the system stability of algae cultivation and improving the living water effect.

[0030] Example 4: This example differs from Example 1 in that, as Figure 5As shown, the ecological filter 2 is equipped with an oxygenation pump 7, which extends into the water body through an air tube, and an air stone 8 is provided at the end of the air tube. It should be noted that both the oxygenation pump 7 and the air stone 8 are commercially available.

[0031] The working principle of the above-mentioned water body living water structure is as follows: the difference from the working principle of Example 1 is that the oxygenation pump 7 can be started to provide auxiliary oxygenation to the deep water body.

[0032] Example 5: The difference between this example and Example 1 is that the ecological floating island 3 is covered with a planting substrate with a thickness of 1 cm. The planting substrate is made of straw and rice husks mixed in a mass ratio of 3:2.

[0033] Example 6: The difference between this example and Example 1 is that the ecological floating island 3 is covered with a planting substrate with a thickness of 2 cm. The planting substrate is made of straw and rice husks mixed in a mass ratio of 5:2.
