Description

Technical Field

[0001] This utility model relates to the field of engineering technology, specifically to a device for micro-improvement of water adaptability in plain river networks. Background Technology

[0002] Plain river networks refer to dense, network-like river systems widely distributed in alluvial plain areas (such as the Jianghan Plain, the Yangtze River Delta, and the Pearl River Delta). The unique geographical environment of these areas creates their typical hydrological characteristics and environmental challenges: Significant hydrological characteristics: Slow water flow and insufficient hydrodynamic force: The overall flow velocity is low, the hydraulic gradient is small, and the hydrodynamic conditions are inherently inadequate. This not only leads to poor pollutant migration and diffusion but is also a core limiting factor for the natural reoxygenation of the water body. The dissolved oxygen replenishment rate is far lower than the consumption rate.

[0003] Water levels fluctuate dramatically, requiring primarily manual regulation: water levels are significantly affected by upstream inflows, artificial dams and gates, pumping station operations, and rainfall, with large variations between flood and dry seasons. Water flow stability is poor.

[0004] Weak water exchange and low self-purification capacity: The network structure leads to complex and long water flow paths, and "dead water zones" (dead ends) are easily formed in some areas. The overall insufficient hydrodynamics and complex morphology result in slow water renewal and limited self-purification capacity.

[0005] Severe environmental challenges: Eutrophication and frequent algal blooms: Susceptible to nutrient pollution from industrial and agricultural non-point source sources, eutrophication is severe under high temperature and sunlight conditions in summer, and large-scale, high-frequency outbreaks of blue-green algae blooms have become the norm.

[0006] High risk of seasonal black and odorous water: Slow-flowing areas and dead-end streams are the hardest hit areas for black and odorous water. When water volume is insufficient, temperature rises, and reoxygenation is insufficient, anaerobic reactions produce odorous substances, leading to widespread seasonal and localized black and odorous water phenomena.

[0007] Sediment pollution is a "time bomb": Slow water flow over a long period causes pollutants (heavy metals, organic matter, nutrients) to accumulate continuously in the sediment, creating a huge endogenous pollution load. Under conditions of disturbance, low oxygen, or temperature changes, these pollutants are easily released into the water, posing a serious risk of secondary pollution.

[0008] Aeration Application Needs and Current Status Insufficient natural reoxygenation capacity of water bodies is one of the root causes of the deterioration of the water environment in plain river networks. The main reasons are: low flow velocity severely limits the gas-liquid exchange rate at the water surface (mainly molecular diffusion); plain river networks are generally shallow, and wind and wave disturbances have limited contribution to the reoxygenation of deep water bodies, making it difficult to penetrate to key oxygen-demanding areas (such as the bottom sediment interface).

[0009] Therefore, artificial oxygenation (aeration) has become a rigid requirement for alleviating the dissolved oxygen crisis and addressing specific scenarios: Wastewater treatment plant effluent disposal: Even if the treated effluent meets the standards, it often contains biodegradable organic matter, which quickly consumes the already insufficient dissolved oxygen after being discharged into the river network.

[0010] Emergency response during high-temperature seasons: High summer temperatures reduce dissolved oxygen saturation, while simultaneously increasing biological oxygen consumption and sediment release, leading to a sharp increase in the risk of fish suffocation and death.

[0011] Sudden pollution incidents: Agricultural non-point source pollution, industrial leaks, pipeline overflows, etc., can cause a sharp increase in local pollutants, which can quickly lead to oxygen deficiency.

[0012] Currently, aeration devices in plain river networks are mainly used in two types of scenarios: First, small-scale demonstration projects, which are deployed in individual black and odorous river sections or key scenic rivers, often combined with measures such as ecological floating islands and aquatic vegetation restoration, focusing on technology demonstration and local effects; Second, emergency treatment projects, which are rapidly deployed in the short term to address sudden black and odorous events or fish surfacing and dying, with the primary goal of improving dissolved oxygen levels.

[0013] However, the unique environmental characteristics of the plain river network pose a severe challenge to the adaptation of conventional aeration technologies: 1. The hydrodynamic environment is complex and variable, making it difficult to guarantee the stability of equipment operation. The dynamic and uncontrollable flow of water, including the velocity, direction, and turbulence intensity of rivers and lakes, is highly dynamic and unpredictable due to multiple factors such as weather, season, gate and pump scheduling, tides (in estuaries), and tributary inflows. The risk of anchorage failure is high. The direct impact of water flow and waves, as well as the "fatigue effect" caused by the long-term reciprocating action of waves and water flow, can easily lead to loosening, deformation, or even complete failure of anchoring systems such as bolts, ropes, and supports, resulting in equipment being washed away, displaced, or structurally damaged.

[0014] Low dispersion efficiency of bubble / air-water mixture: Even a low but continuous forward flow can significantly wash away and elongate the bubble clusters (especially small microporous bubbles) or air-water mixtures (such as impellers and jets) generated by aeration, causing them to quickly leave the effective action area, greatly reducing oxygen transfer efficiency and resulting in serious energy waste.

[0015] Airflow obstruction or even blockage: Direct pressure or impact of water flow on the housing or outlet of the aeration device (especially submersible microporous aeration disc) can cause abnormally high air pressure in the air pipeline, increase the load on the blower, and in severe cases may lead to poor air output or even temporary or permanent blockage of the micropores.

[0016] Pipeline safety hazards are significant: equipment on the water surface or in the water is connected to the shore via pipelines (power supply, gas supply). Problems such as the pulling of water currents, entanglement of floating objects, and untimely release and retraction due to large fluctuations in water level can easily cause pipeline joints to loosen, break, leak, or break, posing a continuous safety threat and risk of operational interruption.

[0017] 2. Dramatic and frequent water level fluctuations result in poor equipment adaptability: The extreme test of "submersion" and "exposure": flood-dry fluctuations of 1-3 meters are the norm.

[0018] High water levels (flood season): Critical electrical equipment such as power supply cabinets and control boxes deployed on or near the shore are easily submerged, causing short circuits, leakage, or even equipment failure.

[0019] Low water levels (dry season): This is disastrous for submersible aeration equipment. Once the microporous aeration discs, jet nozzles, etc. are exposed to the air, direct sunlight causes the plastic / rubber materials to age and crack faster, and dust and debris can enter and clog the micropores or nozzles in a dry environment.

[0020] The Achilles' heel of fixed installations: Most aeration equipment (especially microporous discs fixed at the bottom) cannot automatically adjust their height according to the rise and fall of the water level. During the dry season, the aeration discs are suspended or exposed, while during the flood season, the equipment is either too close to the water surface or sunk into a deeper water layer with lower oxygen utilization efficiency.

[0021] Water surface equipment "idling" during the dry season: When the water level is low, water surface equipment such as float fountains and impeller aerators may suck in air because the impeller or pump body is too close to the water surface or even partially exposed. This can lead to idling, cavitation, overheating of the pump or motor, or even burnout.

[0022] 3. Flood control and navigation channels: Equipment is a potential obstacle. Flood control safety is an absolute red line: As the main flood control and drainage channels in densely populated areas, the unobstructed flow of the plain river network is the lifeline of regional safety, and any obstruction must be met with high vigilance.

[0023] Occupying waterways and increasing roughness: Aeration devices themselves (such as large pontoons and supports), numerous pile foundations (fixing aeration pipes), and huge underwater anchor blocks directly occupy water space and significantly increase local water flow resistance (roughness). During floods, they may raise local water levels, increasing flood control pressure and dike risks.

[0024] Altering flow patterns and threatening bank stability: Equipment and its supporting structures may disrupt local water flow patterns, forming eddies or high-speed zones, exacerbating scouring of the riverbed, slopes, and embankment toes, or causing siltation behind the structures.

[0036] Compared with the prior art, the utility model has the following advantages: 1. Breakthrough improvement of dynamic mooring impact resistance: The spring buffer unit (section L2) absorbs instantaneous impact kinetic energy (wind waves / ship-generated waves) through deformation, preventing stress from being transmitted to the anchoring end; the redundant section L3 passively releases length to cope with continuous water level rise; three rotating figure-eight rings synchronously counteract multi-directional water flow torsion.

The chain risk of traditional fixed equipment "blocking flood → raising water level → washing away equipment / affecting flood discharge" is avoided.

[0039] 3. The geometric anti-overturning structure adopted by the present invention improves the stability of the system: The base of the truncated regular triangular pyramid of the underwater anchoring device has a base triangle aspect ratio of >2:1, which cooperates with a 60° traction angle to form an anti-overturning force arm, and the anti-tipping safety factor of the anchor body under wind waves is significantly improved. The base is welded with a staggered sawtooth array to realize an omnidirectional anti-slip gripping tooth array, which further enhances the engagement between the anchor body and the substrate and prevents "anchor dragging" accidents during the flood period.

[0040] 4. Since the present invention adopts a modular floating body assembly, the compatibility and flexibility of the equipment are improved: A non-destructive quick disassembly function matrix is realized. The buoyancy main pipe and the main beam nested groove are tightly fitted to ensure that the main beam can be replaced without calibration; the double-nut anti-loosening locking of the U-shaped lug plate supports a single person to quickly disassemble and assemble the aeration unit with tools. The "ri"-shaped truss is compatible with various aeration equipment, making the equipment flexible. The buoyancy assembly can be disassembled into individual elements, which facilitates more detailed maintenance and replacement. Brief Description of the Drawings

[0043] The present utility model is further elaborated below with reference to specific examples. It should be understood that these examples are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. After reading the present utility model, various modifications of equivalent forms made by those skilled in the art to the present utility model shall fall within the scope defined by the appended claims of the present application.

[0044] The present utility model application claims to protect a micro-improvement device adaptive to plain river network water, comprising a signal beacon 100, a traction rope system 200A, a water bottom anchoring device 300, a floater assembly 400, and an aeration device, wherein: the signal beacon 100 is a sealed housing structure with positive buoyancy, and the signal beacon 100 is used for real-time monitoring and collection of a variety of meteorological parameter data, and transmits the collected data to a shore-based data center or a cloud platform through its built-in communication device; the traction rope system 200A is detachably connected with the water bottom anchoring device 300 and the floater assembly 400 respectively in the buoyancy assembly connection mode under the conventional water level; the traction rope system 200A is detachably connected with the water bottom anchoring device 300 and the signal beacon 100 respectively in the signal beacon direct connection mode under the flood high water level; the water bottom anchoring device 300 is arranged at the water bottom and used for providing an anchoring point for the device; the floater assembly 400 is a "day"-shaped truss structure, on which the aeration device is arranged.

[0045] It should be noted that, as Figure 1As shown, the signal beacon 100 includes a bottom structure 110 and an upper structure 120. The bottom structure 110 is a hemispherical shell structure. The internal space of the bottom structure 110 shell is sealed and used to protect the internal electronic equipment and power supply system for long-term safe operation in a water environment. The outer surface of the bottom structure 110 shell is smooth and burr-free. This streamlined surface design helps to counteract the hydrodynamic force generated by the water flow, making the device more stable in water. Three “]”-shaped stainless steel connecting arms 111 are equally spaced at the bottom of the hemisphere of the bottom structure 110. The “]”-shaped stainless steel connecting arms 111 are integrally cast structures, and their upper ends are fixedly connected to the bottom of the upper structure 120 to ensure structural strength and uniform stress distribution. The “]”-shaped stainless steel connecting arms 111 are used to provide connection points for the traction rope system 200A. The upper structure 120 includes a column 121, a base 122, and a support rod 123, forming a three-dimensional triangular grid. The structure is a tower-like structure; the column 121 is vertically fixed at the center of the upper surface of the bottom structure 110; the base 122 is fixedly fixed at the upper surface of the bottom structure 110 and extends outward at equal angles along the bottom of the column 121, and the outer frame of the base 122 is an equilateral triangle; the upper end of the support rod 123 is fixedly connected to the upper end of the column 121, and the lower end is fixedly connected to the apex corner of the outer frame of the base 122, and two adjacent support rods 123 form isosceles triangles with the corresponding outer frame of the base 122; the lower ends of the three support rods 123 extend downward and fit closely to the surface of the hemisphere of the bottom structure 110, forming radially distributed "ribs", and the endpoint of the extension of the support rod 123 is fixedly connected to the geometric center point of the hemisphere of the bottom structure 110; multiple solar panels 124 are laid on multiple sides and the top of the triangular grid tower structure formed on the outer side of the upper structure 120; a miniature weather station 125 is installed at the top of the column 121.

[0046] This design is particularly suitable for long-term anchoring or mooring in dynamic waters (such as plains and lakes), effectively resisting the impact of wind, wave, and current loads and cable tension, thus improving the overall stability of the anchoring system.

[0047] The function of the “]” shaped stainless steel connecting arm 111 is to provide an integral, equidistant connection point for the traction rope system 200A. When subjected to external forces (such as ocean currents, waves, and cable tension), this integrated design ensures that the tension is evenly distributed throughout the structure, avoiding localized stress concentration.

[0048] It should be further noted that the bottom structure 110 is made of solid polyethylene or hollow fiberglass. Both materials provide the necessary buoyancy and waterproof seal.

[0049] It should be further explained that the design of the triangular overlapping three-dimensional support rod structure of the upper structure 120 is intended to minimize wind resistance and reduce its own weight, while providing the solar panel 124 with sufficient and as unobstructed as possible exposure space (reducing the impact of its own structure's shadow).

[0050] Solar panels 124 are installed on multiple sides and the top plane (or near-plane) of the triangular grid tower structure. These solar panels 124 are responsible for collecting sunlight to provide the necessary power for the entire device (especially the weather station, communication equipment, and buoyancy components).

[0051] The miniature weather station 125 can monitor and collect various meteorological parameters in real time, including but not limited to: ambient temperature, air humidity, wind speed, wind direction, precipitation (rainfall), atmospheric pressure, and light intensity. The collected meteorological data is transmitted to a shore-based data center or cloud platform via built-in communication equipment (such as a satellite communication module, cellular network, or radio).

[0052] It should be noted that the three "]"-shaped stainless steel connecting arms 111 of the signal beacon 100, the three traction ropes 200, the three pre-set connection surfaces 340 and three stainless steel fixing rings 330 of the underwater anchoring device 300, and the three ear plates 440 of the float assembly 400 are each equipped with text or color identification marks. These identification marks are used to correspond each connection point one by one. Each "]"-shaped stainless steel connecting arm 111 is distinguished by its A, B, C, and red, yellow, and blue markings and colors, corresponding to the traction rope system 200A. It should be noted that, as Figure 7 , 8As shown in Figure 9, the traction rope system 200A includes three identical traction ropes 200; the traction ropes 200, from bottom to top, include a normal water level positioning section 210, a small fluctuation compensation section 220, and a historical high water level reserve section 230; the normal water level positioning section 210 is used to provide basic tension and anchor the float assembly 400 or the signal beacon 100 in the expected position; the end of the normal water level positioning section 210 is provided with a first rotating figure-eight strong shackle 211; the first rotating figure-eight strong shackle 211 is used to connect to the underwater anchoring device 300 and dissipates and releases torque through free rotation relative to the underwater anchoring device 300; the small fluctuation compensation section 220 is used to absorb the impact load generated by transient and small water level fluctuations; the small fluctuation compensation section 220 includes a spring buffer unit 221 and a fixed Two rotating figure-eight rings 222 are fixedly connected to the ropes of the normal water level positioning section 210 and the historical high water level reserve section 230, respectively, at both ends of the spring buffer unit 221. A second rotating figure-eight ring strong shackle 223 is provided on the outer ring of the rotating figure-eight ring 222 at one end of the small fluctuation compensation section 220, which is used to connect to one end of the historical high water level reserve section 230. The second rotating figure-eight ring strong shackle 223 is used to connect the float assembly 400. The historical high water level reserve section 230 is used to connect the signal beacon 100 during floods or high water periods. A third rotating figure-eight ring strong shackle 231 is provided at the end of the historical high water level reserve section 230, and the third rotating figure-eight ring strong shackle 231 is used to connect to the "]" shaped stainless steel connecting arm 111 at the bottom of the signal beacon 100. After connection, the traction rope system 200A forms a multi-point anchoring system to stabilize the connected object. The system design supports both the buoyancy component connection mode under normal water levels and the direct connection mode of the signal beacon under high flood water levels.

[0053] It needs to be further explained that, It should be further noted that the traction rope 200 is made of high-strength polymer fiber rope (such as polyester fiber or aramid fiber), which has high tensile strength, wear resistance and corrosion resistance. The total length of the traction rope 200 is expressed by formula (1): (1) Wherein: L represents the total length of the traction rope 200; L1 represents the length of the normal water level positioning section 210; L2 represents the length of the small fluctuation compensation section 220; L3 represents the length of the historical high water level reserve section 230; The length of the normal water level positioning section 210 is equal to the vertical distance from the design normal water level line to the bottom anchor point; the length range of the small fluctuation compensation section 220 is [0.5m, 1m]. The reserved amount in this section is used to absorb the impact load generated by transient and small water level fluctuations (wind waves, ship waves, and other hydrodynamic effects) through the integrated spring buffer unit at the end, so as to maintain the relatively stable tension of the system; the historical high water level reserve section 230 (reserved for rope sag redundancy) has a length expressed by formula (2): (2) Where: D h Used to characterize the historical highest water level depth; D n Used to characterize the depth of normal water level.

[0054] It should be further explained that the end of the constant water level positioning section 210 is equipped with a first rotating figure-eight shackle 211, which is firmly connected to the underwater anchoring device 300. When the rope is subjected to torque due to water flow impact, wind direction changes, or the rotation of the float, the rotating figure-eight shackle allows the connection point to rotate freely relative to the underwater anchoring device 300, thereby dissipating and releasing the torque and preventing the rope from accumulating twisted turns that could eventually lead to serious entanglement or breakage.

[0055] It should be further noted that a spring buffer unit 221 (the housing is usually made of corrosion-resistant metal such as stainless steel) is integrated near the end of the small fluctuation compensation section 220.

[0056] A rotating figure-eight ring 222 is installed at the output end of the spring buffer unit 221, immediately connected to the ends of both sides of the spring unit. This provides the same core anti-torsion function, dissipating the torque generated by the relative movement between the spring unit and the float assembly 400 or the normal water level positioning section 210 and the historical high water level reserve section 230, preventing the accumulation of torque from causing abnormal operation of the spring unit or entanglement at the connection.

[0057] Among them, the spring buffer unit 221 directly realizes the function of the small fluctuation compensation section 220, buffering instantaneous fluctuation impact.

[0058] Among them, the rotating figure-eight ring 222, while preventing the accumulation of rope torque and entanglement caused by water flow and wind, is connected to the historical high water level reserve section 230. At the other end of the rotating figure-eight ring 222, a second rotating figure-eight ring strong shackle 223 is fixed, providing a standard and quick connection point with the floating body assembly 400.

[0059] It should be further explained that the far end of the historical high water level reserve section 230 is equipped with a third rotating figure-eight ring strong shackle 231, which is specifically used during floods or high water levels to directly hook or connect to the "]"-shaped stainless steel connecting arm 111 at the bottom of the signal beacon 100. The rotating bearing compensates for local torque.

[0060] It should be further explained that the rotating figure-eight shackle has anti-slip textured surfaces for easy operation. The opening and closing lock, through rotation, provides a strong and reliable closed-loop connection, and achieves continuous free anti-torsion through an integrated rotating bearing. The opening and closing locking is a means to ensure a closed-loop connection, not for frequent opening and closing. This ensures high strength, high durability, and anti-torsion reliability in extreme aquatic environments.

[0061] It should be noted that the system operates on the following principle: Connection mode of buoyancy components at normal water levels: Three towing ropes 200 are connected and secured to the float assembly 400 via the second rotating figure-eight ring strong shackle 223 at the end of the small fluctuation compensation section 220 with corresponding color and number.

[0062] At this point, the constant water level positioning section 210 and the small fluctuation compensation section 220 are used to connect the underwater anchoring device 300 to the floating body assembly 400. The constant water level positioning section 210 provides basic anchoring tension, and the spring buffer unit 221 of the small fluctuation compensation section 220 absorbs the impact of water surface fluctuations. The historical high water level reserve section 230 extends from the connection point of the floating body assembly 400 upwards to the shackle at the top of the rope, and is in a completely relaxed, free-hanging state, swinging naturally with the water. Its length is the historical high water level reserve.

[0063] The three-section design protects the beacon from collisions / entanglement with the tow rope, enhances water surface warning, and the operating point is located near the water surface.

[0064] Direct connection mode for signal beacons during high flood levels: Disconnect the float assembly 400 (unlock the second rotating figure-eight shackle 223). Hook and lock the third rotating figure-eight shackle 231 at the top of the historical high water level reserve section 230 of each tow rope 200 directly onto the corresponding “]” shaped stainless steel connecting arm 111 at the bottom of the signal beacon 100, according to the corresponding color and number.

[0065] At this point, the entire rope length is used to connect the underwater anchoring device 300 to the signal beacon 100.

[0066] Among them, the normal water level positioning section 210 is in a (designed) tensioned state, the small fluctuation compensation section 220 is adjusted by a spring, and the historical high water level reserve section 230 is relaxed (reserve).

[0067] During the rising water level period, signal beacon 100 floats with the water level. The tension in the constant water level positioning section 210 gradually decreases, while the spring in the small fluctuation compensation section 220 continues to work to buffer instantaneous impacts. The historical high water level reserve section 230 is passively released (the overall system relaxation increases).

[0068] When the historical highest water level is reached, the entire traction rope 200 is adjusted to a critical state (the spring buffer unit 221 responds to the hydrodynamic influence) to ensure that the signal beacon 100 is effectively anchored.

[0069] When the water level drops, the process reverses, the rope slack decreases, and the tension is restored.

[0070] The spring buffer unit 221 operates continuously throughout the process.

[0071] The range of motion of the signal beacon 100 is a complex three-dimensional space, determined by the effective length and tension state of the three tow ropes 200 in direct connection mode (controlled by spring buffers and system slack) as well as the dynamic loads on the water (ship movement, wind, waves). Multi-point mooring provides relatively stable positioning capabilities.

[0072] It should be noted that, as Figure 6 As shown, the underwater anchoring device 300 includes a main body 310, gripping teeth 320, and a stainless steel fixing ring 330. The main body 310 is a precast reinforced concrete truncated regular triangular pyramid geometric structure, with a high-strength steel reinforcement skeleton embedded inside. This geometric design provides a dual stability foundation. The bottom plane of the main body 310 is an equilateral triangle, providing a wide base support surface and forming a wide moment arm, significantly improving the ability to resist the overturning moment of wind and waves. The side surface is an isosceles trapezoid, and adjacent isosceles trapezoids are connected by oblique cuts to form a pre-set isosceles triangle connection surface 34. 0; The top plane of the main body 310 is a regular hexagonal platform 350, which is formed by flattening the top of the original regular triangular pyramid, providing a regular, symmetrical and reinforced support surface for the connection of the traction system; A stainless steel fixing ring 330 is pre-embedded in the center of each preset connection surface 340; The stainless steel fixing ring 330 is anchored to the steel reinforcement skeleton inside the main body 310 by full penetration welding, providing high tensile bearing capacity and long-term corrosion resistance; Multiple rows of staggered gripping teeth 320 are welded on the bottom surface of the main body 310, which significantly increases the base friction coefficient and prevents the device from settling.

[0073] It should be further noted that the main body 310 is precast reinforced concrete with a grade ≥ C40, and anti-corrosion additives are added to meet the comprehensive requirements of compressive strength, durability, and resistance to chemical corrosion in the underwater environment. The steel reinforcement cage must be epoxy coated or cathodic protected to effectively prevent corrosion caused by chloride ion penetration. Each pre-set connection surface 340 forms a 60° angle with the bottom surface of the main body 310 (along the direction of the lateral edge of the truncated regular triangular pyramid); each pre-set connection surface 340 itself is a small equilateral triangular plane, used to optimize stress distribution and disperse localized concentrated loads from the traction rope 200.

[0074] It should be further noted that the three pre-designed connection surfaces 340 and their fixing rings are marked with the letters A, B, and C respectively, and painted with red, yellow, and blue circular stripes. This standardized marking system ensures quick visual matching with the corresponding markings at the end of the traction rope 200, effectively preventing misoperation during connection.

[0075] It is necessary to further explain the mechanical principles of the traction system: Three traction ropes 200 are respectively connected to three stainless steel fixing rings 330 on three preset connection surfaces 340, and are distributed at a strict 120° equal angle on the horizontal plane.

[0076] Horizontal tensile forces from any direction can all be resisted by the combined tension force of at least two pulling ropes 200, thereby greatly suppressing the horizontal drift of the floating body.

[0077] The wide triangular base combined with the traction force action points distributed in three directions at 120° constitutes a powerful anti-overturning system, which effectively counteracts the overturning moment caused by wind and waves.

[0078] It should be noted that, as shown in Figure 2 , 3 , 4 and 5, the floating body assembly 400 includes a main buoyancy pipe 410, a main beam 420, a secondary beam 430 and an ear plate 440; the main buoyancy pipe 410, as the core load-bearing and buoyancy unit, comprises 3 HDPE spiral pipes arranged in parallel at equal intervals, the interior of which is filled with a filling material (closed-cell polyurethane foam) for providing buoyancy, ensuring permanent positive buoyancy and leak resistance; the horizontal spacing of the main buoyancy pipes 410 is strictly defined by geometric constraints: the connecting lines between the two end points of the two outer main buoyancy pipes 410 and the midpoint of the middle main buoyancy pipe 410 respectively form equilateral triangles; on both sides of the internal axis of the main buoyancy pipe 410, main beam embedding grooves for nesting and inserting the main beams 420 are provided, and the length of the main beam embedding grooves runs through the entire length of the main buoyancy pipe 410, realizing the integration of load-bearing of the main pipe and the main beams; on the top surface of the main beam 420 near both ends, secondary beam positioning grooves 450 for positioning the secondary beam 430 are symmetrically arranged, which provide operation space for bolt fastening of the secondary beam and restrict the position of the secondary beam, while avoiding excessive weakening of the structural strength of the main pipe; the main beams 420 are three square steel pipes longitudinally nested in the main beam embedding grooves, and the side surfaces of their ends are provided with ear plate mounting holes 421 for fixing the ear plates 440; the ear plate mounting holes 421 on the two outer main beams 420 are disposed on the left side, and the ear plate mounting holes 421 on the middle main beam 420 are disposed on the right side; the secondary beams 430 are two square steel pipes transversely disposed in the secondary beam positioning grooves 450; after the main beams 420, the secondary beams 430 and the main buoyancy pipe 410 are assembled as a whole, they are connected by high-strength bolts 460, and form a "day"-shaped frame structure; the ear plate 440 is a U-shaped shackle structure, and its two ports are respectively attached to both sides of the ear plate mounting hole 421 of the main beam 420; the ear plate 440 is mounted on the main beam 420 by passing a high-strength through bolt 470 through the ear plate mounting hole 421 and the two shackle leg holes 441 of the ear plate 440, and then locking with double nuts 442; the ear plate 440 is used for the second rotating figure-eight ring high-strength shackle 223 of the pulling rope system 200A.

[0079] It should be further noted that the filling material in the main buoyancy pipe 410 is closed-cell polyurethane foam; the cross-sectional dimension of the main beam embedding groove is the side length of the square steel pipe of the main beam 420 plus 2mm; the width of the secondary beam positioning groove 450 is the side length of the square steel pipe of the secondary beam 430 plus 2mm, and the depth of the secondary beam positioning groove 450 is less than 0.4 times the pipe diameter of the main buoyancy pipe 410.

[0080] It should be further noted that the frame system of main beam 420 and secondary beam 430 is as follows: Main beam 420: Hot-dip galvanized square steel pipe is used as the longitudinal load-bearing core. The main beam 420 is inserted and nested in the main beam nesting groove of the main buoyancy pipe 410 to form a tight mechanical load-bearing structure; prefabricated lug plate mounting holes 421 are provided on the side of its end for fixing the lug plate 440.

[0081] Secondary beam 430: Hot-dip galvanized square steel pipe is used as the lateral stabilizing member. High-strength bolts pass downward through the secondary beam positioning groove 450 and are directly locked to the pre-set screw holes on the top of the main beam 420.

[0082] Structural topological relationship: The main beam 420 traverses three main buoyancy pipes 410 laterally to form the horizontal strokes of a "Japanese" character; the secondary beam 430 is vertically connected across the main beams 420 to form the two vertical strokes on both sides of the "Japanese" character. This structure forms a space truss with extremely high torsional rigidity, which effectively distributes the dynamic load of the water body.

[0083] It should be further noted that the structure of the lug plate connection system is as follows: The lug plate 440 adopts a U-shaped shackle structure (high-strength alloy steel forging, hot-dip galvanized for corrosion protection), the ports of which are respectively attached to both sides of the end of the main beam 420, and high-strength through bolts 470 pass through the lug plate mounting holes 421 and the two shackle leg holes 441 of the lug plate 440, and are locked with double nuts 442 for anti-loosening. The installation positions are strictly corresponding as follows: Lug plate A (red): Fixed at the left end of the leftmost main beam 420, corresponding to the pipe end mark A / red band.

[0084] Lug plate B (yellow): Fixed at the right part of the middle main beam 420, corresponding to the pipe end mark B / yellow band.

[0085] Lug plate C (blue): Fixed at the left end of the rightmost main beam 420, corresponding to the pipe end mark C / blue band.

[0086] It should be further noted that the base of the aeration device adopts a perforated aluminum plate grid, which is laid on the top of the secondary beam 430 to reduce self-weight and support instantaneous drainage; the base of the aeration device is locked on the surface of the perforated aluminum plate grid by U-shaped hoops with neoprene pads, and the rubber pads provide vibration buffering and anti-slip functions; nylon blocks are added between the hoops and the aluminum plate to disperse the compressive stress and avoid grid deformation.

[0087] It should be noted that the following is the full disaster prevention response process of the present device (taking flood event as an example): Stage I: Conventional operation in non-flood period (aeration mode) System state anchor points: The towing rope system consists of three ropes, L1 and L2 sections, which are connected to the float assembly lugs (A / red, B / yellow, C / blue correspond one-to-one) via shackles at the end of L2.

[0088] Signal Beacon 100: Suspended on the water surface, with L3 segment relaxed and drooping.

[0089] Floating assembly 400: The waterline is maintained at the design normal water level.

[0090] Aeration device: fixed by a secondary beam aluminum plate grid base. Phase II: Flood Warning Response (Mode Switching Preparation) Water level monitoring logic: Warning activation: Current water level > normal water level + 0.8m → triggered by water level sensor → manual assessment and decision-making.

[0091] Human-based decision-making: On-site assessment: Technicians arrive at the shore and visually compare the water level gauge (error <10cm).

[0092] By combining the background data and historical water level curves, the trend is confirmed. If the rise rate is ≥ 10cm / h, the flood emergency response is initiated. Phase III: Peak Flood Season (Direct Anchoring Mode for Signal Beacons) Mechanical transmission chain: water flow impact → streamlined hemispherical guide for signal beacon → force components of three traction ropes (120° symmetrical) → pull-out resistance of anchoring device. Rope tension path: anchor point fixing ring → L1 → spring unit (L2) → L3 → signal beacon connecting arm.

[0093] Phase IV: Drainage and Reset (System Reconstruction) The lossless transmission of disaster response is achieved through "rope-tethered physical reconstruction" (buoy switching), "mechanical error prevention design" (ABC color code closed loop), and "structural mechanics optimization" (anti-overturning / streamlined / force-component anchoring). No new data is added throughout the process, and it relies entirely on existing technical features.
