Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to a self-balancing floating type water conservancy sewage interception device. Background Technology

[0002] In the water environment management of open water areas such as rivers, lakes, and reservoirs, water conservancy interception equipment is the core equipment for intercepting floating garbage, aquatic plants, and various debris on the water surface.

[0003] Currently, most traditional water conservancy sewage interception equipment adopts a fixed rigid frame structure, which has low overall adaptability and automation level. In practical applications, it has many defects. Its filter screen is easily clogged by garbage and silt after long-term use, requiring manual cleaning on shore. This not only results in high operation and maintenance costs and labor intensity, but also interrupts sewage interception operations and affects treatment efficiency. Moreover, the equipment lacks an automatic unclogging structure and cannot perform cleaning actions autonomously according to the clogging status of the filter screen, resulting in poor anti-clogging and unclogging effects. It cannot meet the current requirements for efficient, stable, automated, and long-term operation and maintenance of sewage interception in water areas. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention aims to provide a self-balancing floating water conservancy interception device. This solution enables automatic cleaning and active anti-clogging of the filter screen without manual intervention, fundamentally solving the problem of easy clogging of the filter screen, reducing equipment operation and maintenance costs and labor intensity, and improving the efficiency of water area interception.

[0005] This invention is achieved through the following technical solution:

[0006] A self-balancing floating type water conservancy sewage interception device, comprising:

[0007] A floating unit that can float on the water surface;

[0008] A barrier filter screen is connected to the float unit and suspended below the float unit;

[0009] A cleaning unit is connected to the float unit and is located on the side of the barrier filter facing away from the water flow direction;

[0010] The cleaning unit includes a lifting drive, a crossbar, and a cleaning component. The lifting drive is used to drive the crossbar to move up and down along the height direction of the barrier filter. The cleaning component is fixed to the side of the crossbar facing the barrier filter and is arranged along the length direction of the crossbar.

[0011] The raising and lowering of the crossbar is used to drive the cleaning component to abut against the surface of the filter screen and scrape or brush away the contaminants attached to the filter screen.

[0012] Compared to existing technologies where the filter screen requires manual cleaning ashore and lacks an automatic unclogging structure, this invention provides a self-balancing floating water conservancy interception device. This solution enables automatic unclogging and active anti-clogging of the filter screen, eliminating the need for manual intervention and fundamentally solving the problem of easy clogging. It reduces equipment maintenance costs and labor intensity, and improves the efficiency of water conservancy interception. Specifically, the solution includes a floating unit, and a filter screen and cleaning unit located at the bottom of the floating unit. The floating unit serves as the core buoyancy support, supporting the filter screen and cleaning unit and ensuring the overall stability of the equipment. It can adopt structures such as a bladder or pontoon. The barrier filter is connected to the underside of the float unit via a filter structure mounting component. This component may include several U-shaped plates, evenly spaced along the length of the float unit and fixed to its underside with their openings facing downwards. Bolts or pins pass through both sides of the U-shaped plates, simultaneously passing through the upper part of the barrier filter, thus detachably securing the filter. The mounting component provides a standardized installation interface for the barrier filter, enabling rapid disassembly and fixation, improving equipment assembly and maintenance efficiency. The barrier filter is used to intercept floating garbage, aquatic plants, debris, and other pollutants in water bodies. Its detachable design facilitates cleaning and replacement, preventing the filter from becoming unusable after damage. The cleaning unit is located on the side of the barrier filter facing away from the water flow direction. It includes a lifting drive, a crossbar, and a cleaning component. The cleaning component can use a scraper, steel brush, or similar structure, and its working surface can contact the barrier filter. Therefore, driven by the lifting drive component, the crossbar moves up and down, which can drive the cleaning component to scrape or brush away the pollutants attached to the filter screen, as well as the silt, garbage and other blockages in the filter screen pores, keeping the filter screen clear, ensuring the efficiency of dirt interception, and realizing automatic cleaning of the filter screen without the need for manual intervention.

[0013] To further optimize the filter screen and improve its anti-clogging and unclogging effects, permanent magnets are provided at both ends of the crossbar on the side facing the filter screen.

[0014] The barrier filter is equipped with magnetic components at the positions corresponding to the two permanent magnets;

[0015] The magnetic component includes several strongly magnetic metals arranged at intervals along the height of the barrier filter. The raising and lowering of the crossbar allows the magnetic component to sequentially attract these strongly magnetic metals. In this design, the barrier filter can be a flexible structure, eliminating the need for a rigid frame in its circumferential direction to reduce overall weight. On the side of the barrier filter facing away from the water flow direction, magnetic components are vertically arranged on both sides, consisting of several strongly magnetic metals arranged at intervals. Permanent magnets are correspondingly located at both ends of the crossbar facing the barrier filter. Thus, during the up-and-down movement of the crossbar, the permanent magnets sequentially attract the passing strongly magnetic metals, forming a magnetic attraction with them. This enhances the cleaning force between the cleaning components and the barrier filter, improving cleaning efficiency, and also causes the barrier filter to sway, thus strengthening the anti-clogging effect. The magnetic attraction force of the permanent magnets and the strongly magnetic metals is designed to ensure that the driving force of the lifting drive is sufficient to disengage the permanent magnets and the strongly magnetic metals.

[0016] To further optimize the cleaning unit and achieve stable lifting and lowering of the crossbar, the cleaning unit also includes at least two guide rods fixed to the float unit. These guide rods are located below the float unit and are positioned along the lifting and lowering direction of the crossbar. Each end of the crossbar is slidably connected to a guide rod. In this design, the upper end of the guide rod is detachably connected to the float unit, providing a vertical linear sliding track for the crossbar, limiting its movement path, and ensuring precise up-and-down movement of the cleaning component along the filter screen, preventing deviation and cleaning failure. Furthermore, a sliding connector is slidably fitted onto the guide rod, and the end of the crossbar is preferably hinged to the sliding connector. This hinged connection can accommodate slight deformation of the filter screen, ensuring a flexible and secure cleaning structure without jamming.

[0017] Further optimization involves the automatic lifting and lowering of the crossbar and cleaning components. Several lifting drive components are distributed on the crossbar, and all of these lifting drive components are located below the floating body unit.

[0018] The lifting drive component includes a waterproof support frame, a vertical propeller, and a horizontal propeller.

[0019] The waterproof support frame has a sealed chamber;

[0020] The shaft section of the transverse propeller is transversely perpendicular to the filter screen, and one end of the shaft section passes through a bearing into the sealed chamber and is connected to an active conical tooth.

[0021] The shaft section of the vertical propeller is vertically arranged, and its lower end passes through a bearing into a sealed cavity and is connected to a driven conical tooth.

[0022] The active and driven conical teeth mesh with each other. In this design, the lifting drive mainly includes a waterproof support frame, a vertical helical rod, and a horizontal helical rod. One end of the waterproof support frame is detachably fixed to the crossbar, and the other end has a sealed chamber. The front and upper sides of the sealed chamber have through holes, and bearings are installed inside the through holes. The bottom of the vertical helical rod extends into the sealed chamber through a sealed bearing, and one end of the horizontal helical rod extends into the sealed chamber through a sealed bearing. The internal extension end is sealed through the sealed chamber to prevent water from entering the drive structure and ensure the stable operation of the transmission components. The extension end of the vertical helical rod is provided with a driven conical tooth that meshes with the active conical tooth, receives power, and reverses the direction to drive the vertical helical rod. The extension end of the horizontal helical rod is provided with an active conical tooth that transmits power to the horizontal helical rod. It cooperates with the driven conical tooth to achieve power reversal and synchronous transmission. The active and driven conical teeth mesh and connect to achieve power reversal and synchronous transmission, transferring the power of the horizontal helical rod to the vertical helical rod, completing the power conversion. The horizontal propeller automatically adjusts its speed according to the water flow velocity, providing power to the vertical propeller and simultaneously guiding debris towards the filter screen. In operation, the faster the water flow, the higher the horizontal propeller's rotation speed. The active and driven conical teeth mesh to transmit power synchronously to the vertical propeller, causing it to rotate at high speed. The vertical propeller's vertical orientation generates upward thrust, driving the crossbar to overcome its own weight and move upward along the guide rod, comprehensively intercepting pollutants such as garbage, weeds, and debris in the water, stably completing the water interception operation. When debris clogs the filter screen, the water flow is obstructed, causing a decrease in water velocity. The horizontal propeller's speed decreases accordingly, and the vertical propeller's speed decreases simultaneously. The upward thrust gradually decreases, and the crossbar, unable to overcome its own weight, falls back down along the guide rod, working in conjunction with the cleaning components to thoroughly clean the filter screen. The entire process requires no manual intervention, maintaining the filter screen's permeability and ensuring continuous and efficient debris interception.

[0023] To further optimize the process and prevent contaminants from getting tangled on the cleaning component, a scraper is used.

[0024] Further optimization provides vertical gravity to the filter screen, keeping it vertically unfolded in the water, preventing it from floating and curling, and ensuring the coverage area and interception effect of the pollutants. The bottom of the filter screen is connected to a filter screen counterweight.

[0025] Further optimization is needed because traditional equipment cannot autonomously adjust the attitude of the floating body according to the impact force of water flow and the amplitude of wave fluctuations. Under complex water flow conditions, it is prone to floating imbalance and overturning, resulting in poor stability of sewage interception operations. Moreover, most of them are integrated structures with weak modular splicing capabilities, making it difficult to adapt to the sewage interception needs of water areas with different widths. Therefore, in order to avoid the overturning and splicing of floating bodies, the floating body unit includes several floating bodies that are hinged together in sequence.

[0026] Further optimization, as a hinged connection method, includes several intermediate floats and several side floats among the several floats;

[0027] At least one connecting frame is fixedly installed on both sides of the intermediate float;

[0028] At least one floating hinge is provided on each side of the side float. The end of the floating hinge facing the connecting frame has a slot for the end of the connecting frame to be inserted. The slot is through the top and bottom.

[0029] One side of the side float is connected to a corresponding connecting frame via a floating hinge, and a rotating pin passes longitudinally between the slot of the floating hinge and the end of the connecting frame. In this design, two connecting frames are provided on both sides of the intermediate float to provide a rigid mounting base for the floating hinge, fix the hinge position, transmit the force between the floats, and prevent the connection from loosening and falling off. Floating hinges are connected to the corresponding side floats on both sides. One end of each floating hinge has a slot that extends vertically for the connecting frame to insert, and a rotating pin extends longitudinally to achieve vertical hinge rotation. A single intermediate float and two side floats constitute a buoyancy unit. As a basic modular component, this allows for rapid assembly of multiple units, adapting to the needs of intercepting sewage in waters of different widths, and improving the equipment's versatility and installation efficiency.

[0030] Further optimization, to improve the articulation capability and achieve adaptive angle adjustment, includes a groove at the connection point of the side float with the floating hinge. Two vertically arranged waterproof spring telescopic rods are housed within this groove. The end of the floating hinge furthest from the connecting frame extends into the groove and connects between the two waterproof spring telescopic rods. In this design, each waterproof spring telescopic rod has an inner and an outer cylinder. The inner cylinder can extend and retract under the influence of a spring, and preferably, it can achieve axial deflection. The upper and lower ends of the floating hinge are detachably connected to the inner cylinders of the two waterproof spring telescopic rods, respectively. This allows the floating hinge to achieve vertical displacement and forward / backward deflection. Two waterproof spring telescopic rods form a group, with multiple groups evenly distributed to balance the force on the side floats, enhancing resistance to water flow impact and improving adaptive balance stability. The waterproof spring telescopic rods automatically and elastically expand and contract with the impact of waves and water flow, offsetting external forces and maintaining equipment balance. The detachable design facilitates quick replacement after damage, reducing maintenance costs. The ends of the four waterproof spring telescopic rods on the same side are connected to the side floats, which, together with the middle float, increase the water surface contact area and improve floating stability. At the same time, they provide an installation carrier for intercepting debris, clearing blockages, and buoyancy control components. For example, two groups of waterproof spring telescopic rods on the side of one side float are respectively equipped with first side connectors, which match and connect with second side connectors to achieve quick splicing and fixing of multiple buoyancy units. Two groups of waterproof spring telescopic rods on the side of another side float are respectively equipped with second side connectors, which, together with the first side connectors, form a continuous debris interception strip, suitable for intercepting debris in wide water areas. The first side connector and the floating hinge have the same structure, and the second side connector and the connecting frame have the same structure, but the second side connector is connected to two waterproof spring telescopic rods on the side float.

[0031] Further optimization is needed because the buoyancy of traditional sewage interception equipment is not adjustable, and the float is prone to sinking due to excessive water immersion. Therefore, in order to achieve the adjustment of the buoyancy of the float, the bottom of the float is also equipped with a water inlet pipe and a drain outlet that are connected to its internal chamber. The water inlet pipe and the drain outlet are both connected to a miniature waterproof solenoid valve at one end of the internal chamber of the float.

[0032] The float is also equipped with a miniature water pump connected to an inlet pipe. In this design, each side float has an inlet pipe and a drain outlet at its bottom. The pump introduces external water into the side float, allowing for precise buoyancy control through the drain outlet and adjustment of the internal water volume. A drain outlet is located at the bottom of each side float opposite the inlet pipe to drain excess water, further assisting in buoyancy regulation and preventing excessive water ingress and sinking. A detachable protective filter is installed at one end of the inlet pipe to intercept debris and prevent blockage, ensuring unobstructed buoyancy control. The detachable design facilitates cleaning and maintenance. Furthermore, the tops of both the inlet and drain outlets extend into the side float, allowing water to flow in and out, providing a channel for buoyancy adjustment. Miniature waterproof solenoid valves are installed at the top of both the inlet and drain outlets, automatically controlling the flow from sensors to achieve intelligent, automatic buoyancy adjustment without manual intervention. Two miniature water pumps can be installed within the side floats, connected to the inlet pipe and outlet respectively, to draw in and discharge water. Additionally, electrode-type immersion sensors are installed at the top rear edge of both side floats to monitor the immersion depth and water level in real time, transmitting signals to a solenoid valve to trigger buoyancy adjustment and ensure safe floating of the equipment.

[0033] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0034] 1. The present invention provides a self-balancing floating water interception device, which has an adaptive balance structure formed by the cooperation of waterproof spring telescopic rod and floating hinge, which can automatically correct the floating body attitude with water flow and waves, effectively avoid equipment imbalance and overturning, and greatly improve the operational stability of the equipment in complex waters.

[0035] 2. The present invention provides a self-balancing floating water interception device, which achieves automatic cleaning and active anti-clogging of the filter screen by a dual design of water flow speed driving propeller in conjunction with crossbar lifting and lowering, and permanent magnet and strong magnetic metal magnetic attraction to shake the filter screen. It does not require manual intervention to clean, fundamentally solves the problem of easy clogging of the filter screen, and reduces equipment operation and maintenance costs and labor intensity.

[0036] 3. The present invention provides a self-balancing floating water interception device, which uses an intelligent buoyancy control system with an electrode-type water immersion sensor and a miniature waterproof solenoid valve to automatically adjust the water volume inside the float, maintain stable buoyancy of the device at all times, prevent the float from sinking due to excessive water immersion, and significantly improve the safety and reliability of the device operation.

[0037] 4. The self-balancing floating water conservancy interception device provided by the present invention, through the combination design of modular buoyancy units and side connectors, can be quickly spliced ​​to form a continuous interception belt according to the width of the water area, which is suitable for various water areas such as rivers, lakes, and reservoirs. The device is easy to assemble and disassemble, has strong versatility, and has good promotion and application value. Attached Figure Description

[0047] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of the present invention are only used to explain the present invention and are not intended to limit the present invention.

[0048] Example 1: This Example 1 provides a self-balancing floating type water conservancy sewage interception device, such as... Figures 1-6 As shown, it includes:

[0049] A floating unit that can float on the water surface;

[0050] The filter screen 5 is connected to the float unit and is suspended below the float unit;

[0051] A cleaning unit is connected to the float unit and is located on the side of the barrier filter 5 away from the direction of water flow.

[0052] The cleaning unit includes a lifting drive, a crossbar 14 and a cleaning component 20. The lifting drive is used to drive the crossbar 14 to move up and down along the height direction of the barrier filter 5. The cleaning component 20 is fixed to the side of the crossbar 14 facing the barrier filter 5 and is arranged along the length direction of the crossbar 14.

[0053] The lifting and lowering of the crossbar 14 is used to drive the cleaning component 20 to abut against the surface of the barrier filter 5, and to scrape or brush away the contaminants attached to the barrier filter 5.

[0054] Compared to existing technologies where the filter screen 5 requires manual cleaning ashore and lacks an automatic unclogging structure, this invention provides a self-balancing floating water conservancy interception device. This solution enables automatic unclogging and active anti-clogging of the filter screen 5, eliminating the need for manual intervention and fundamentally solving the problem of easy clogging. It reduces equipment maintenance costs and labor intensity, and improves the efficiency of water conservancy interception. Specifically, the solution includes a floating unit, and the filter screen 5 and cleaning unit located at the bottom of the floating unit. The floating unit serves as the core buoyancy support, supporting the filter screen 5 and cleaning unit, ensuring the overall stability of the equipment. It can adopt structures such as a bladder or pontoon. The barrier filter 5 is connected to the lower side of the float unit via a filter structure mounting component 22. The filter structure mounting component 22 may include several U-shaped plates, which are evenly spaced along the length of the float unit and fixed to the lower side of the float unit with their openings facing downwards. Bolts or pins pass through both sides of the U-shaped plates to simultaneously pass through the upper end of the barrier filter 5, thus detachably fixing the barrier filter 5. The filter structure mounting component 22 provides a standardized installation interface for the barrier filter 5, enabling quick disassembly and fixing of the filter, improving equipment assembly and maintenance efficiency. The barrier filter 5 is used to intercept floating garbage, aquatic plants, debris, and other pollutants in the water. Its detachable design facilitates cleaning and replacement, preventing the filter from being completely scrapped after damage. The cleaning unit is located on the side of the barrier filter 5 away from the water flow direction. It includes a lifting drive component, a crossbar 14, and a cleaning component 20. The cleaning component 20 may use a scraper, steel brush, or similar structure, and its working surface can abut against the barrier filter 5. Therefore, driven by the lifting drive component, the crossbar 14 is raised and lowered, which can drive the cleaning component 20 to scrape or brush away the pollutants attached to the filter screen 5, as well as the silt, garbage and other blockages in the filter screen pores, keep the filter screen transparent, ensure the efficiency of dirt interception, and realize the automatic cleaning of the filter screen 5 without manual intervention.

[0055] In this embodiment, in order to improve the anti-clogging and unclogging effect of the barrier filter 5, permanent magnets 21 are provided at both ends of the crossbar 14 on the side facing the barrier filter 5.

[0056] The barrier filter 5 is provided with magnetic components at the positions corresponding to the two permanent magnets 21;

[0057] The magnetic component includes a plurality of strongly magnetic metals 9 arranged at intervals along the height direction of the barrier filter 5; the raising and lowering of the crossbar 14 enables the magnetic component to sequentially attract the plurality of strongly magnetic metals 9. In this design, the barrier filter 5 can adopt a flexible structure, eliminating the need for a rigid frame in its circumferential direction to reduce overall weight. On the side of the barrier filter 5 facing away from the water flow direction, magnetic components are vertically arranged on both sides, consisting of several strongly magnetic metals 9 arranged at intervals. Permanent magnets 21 are correspondingly located at both ends of the crossbar 14 facing the barrier filter 5. Thus, as the crossbar 14 moves up and down, the permanent magnets 21 sequentially attract the passing strongly magnetic metals 9, forming a magnetic attraction with them. This increases the force between the cleaning component 20 and the barrier filter 5, enhancing cleaning ability, and also causes the barrier filter 5 to shake, thereby strengthening the anti-clogging effect. The magnetic attraction of the permanent magnets 21 and the strongly magnetic metals 9 is designed to ensure that the driving force of the lifting drive component is sufficient to push the permanent magnets 21 and the strongly magnetic metals 9 away from each other.

[0058] Example 2: Based on Example 1, Example 2 provides an automated drive structure for a cleaning unit, such as... Figures 3-5 As shown.

[0059] In this embodiment, to achieve stable lifting and lowering of the crossbar 14, the cleaning unit further includes at least two guide rods 10 fixed to the float unit. The guide rods 10 are located below the float unit and are arranged along the lifting and lowering direction of the crossbar 14. Each end of the crossbar 14 is slidably connected to a guide rod 10. In this design, the upper end of the guide rod 10 is detachably connected to the float unit, providing a vertical linear sliding track for the crossbar 14, limiting the movement path of the crossbar 14, and ensuring that the cleaning component 20 moves precisely up and down along the barrier filter 5, avoiding deviation and clogging failure. Furthermore, a sliding connector is slidably fitted onto the guide rod 10, and the end of the crossbar 14 is preferably hinged to the sliding connector. This hinged connection can accommodate slight deformation of the filter, ensuring that the clogging-clearing structure fits flexibly and without jamming.

[0060] In this embodiment, in order to realize the automatic lifting and lowering of the crossbar 14 and the cleaning component 20, a plurality of lifting drive components are distributed on the crossbar 14, and the plurality of lifting drive components are all located below the floating body unit.

[0061] The lifting drive unit includes a waterproof support frame 19, a vertical propeller 15, and a horizontal propeller 16.

[0062] The waterproof support frame 19 has a sealed chamber;

[0063] The shaft section of the transverse propeller 16 is transversely perpendicular to the barrier filter 5, and one end of its shaft section passes through the bearing into the sealed cavity and is connected to the active conical tooth 17.

[0064] The shaft section of the vertical propeller 15 is vertically arranged, and the lower end of the shaft section passes through a bearing into the sealed cavity and is connected to a driven conical tooth 18.

[0065] The active conical tooth 17 and the driven conical tooth 18 mesh with each other. In this design, the lifting drive mainly includes a waterproof support frame 19, a vertical helical rod, and a horizontal helical rod. One end of the waterproof support frame 19 is detachably fixed to the crossbar 14, and the other end has a sealed chamber. The front and upper sides of the sealed chamber have through holes, and bearings are installed in the through holes. The bottom of the vertical helical rod extends into the sealed chamber through a sealed bearing, and one end of the horizontal propeller 16 extends into the sealed chamber through a sealed bearing. The built-in extension end is sealed through the sealed chamber to prevent water from entering the drive structure and ensure the stable operation of the transmission components. The extended end of the vertical propeller 15 is provided with a driven conical tooth 18, which meshes with the driving conical tooth 17 to receive power and reverse the direction of the vertical propeller 15. The extended end of the horizontal propeller 16 is provided with a driving conical tooth 17, which transmits power to the horizontal propeller 16. It cooperates with the driven conical tooth 18 to realize power reversal and synchronous transmission. The driving conical tooth 17 and the driven conical tooth 18 mesh and connect to realize power reversal and synchronous transmission, transferring the power of the horizontal propeller 16 to the vertical propeller 15, thus completing the power conversion. Among them, the horizontal propeller 16 can automatically adjust its rotation speed according to the water flow speed to provide power to the vertical propeller 15, while also helping to guide dirt closer to the filter screen. In actual operation, the faster the water flow, the higher the rotation speed of the horizontal propeller 16. The active conical tooth 17 and the driven conical tooth 18 mesh and transmit power synchronously to the vertical propeller 15, causing it to rotate at high speed. The vertical propeller 15, with its vertical orientation, generates an upward thrust, causing the crossbar 14 to overcome its own weight and move upward along the guide rod 10, thus comprehensively intercepting pollutants such as garbage, aquatic plants, and debris in the water, and stably completing the water interception operation. When debris adheres to the surface of the filter screen 5 and causes blockage, the water flow is obstructed, resulting in a decrease in water flow speed. The rotation speed of the horizontal propeller 16 slows down accordingly, and the rotation speed of the vertical propeller 15 slows down simultaneously. The upward thrust gradually decreases, and the crossbar 14 cannot overcome its own weight and falls back down along the guide rod 10. This, combined with the cleaning component 20, completes the comprehensive cleaning of the filter screen 5. No manual intervention is required throughout the process, keeping the filter screen clear and ensuring the continuous and efficient operation of the interception operation.

[0066] In this embodiment, to prevent contaminants from getting tangled on the cleaning component 20, the cleaning component 20 is a scraper.

[0067] In this embodiment, vertical gravity is provided to the filter screen to keep it vertically unfolded in the water, preventing it from floating and curling up, and ensuring the coverage area and interception effect of the intercepting filter screen 5. The bottom of the blocking filter screen 5 is connected to the filter screen counterweight 501.

[0068] Example 3: Based on Example 1 or 2, Example 3 provides a floating body unit that self-adjusts the attitude of the floating body, such as... Figure 2 As shown.

[0069] In this embodiment, since traditional equipment cannot autonomously adjust the attitude of the floating body according to the impact force of water flow and the amplitude of wave fluctuations, it is prone to floating imbalance and overturning under complex water flow conditions, resulting in poor stability of sewage interception operations. Moreover, most of them are integrated structures with weak modular splicing capabilities, making it difficult to adapt to the sewage interception needs of water areas with different widths. Therefore, in order to avoid the overturning and splicing of floating bodies, the floating body unit includes several floating bodies that are sequentially hinged together.

[0070] In this embodiment, as a hinged connection method, the plurality of floating bodies include a plurality of intermediate floating bodies 1 and a plurality of side floating bodies 2;

[0071] At least one connecting frame 7 is fixedly provided on both sides of the intermediate float 1;

[0072] At least one floating hinge 6 is provided on both sides of the side float 2. The end of the floating hinge 6 facing the connecting frame 7 has a slot for the end of the connecting frame 7 to be inserted. The slot is through the top and bottom.

[0073] One side of the side float 2 is connected to a corresponding connecting frame 7 via a floating hinge 6, and a rotating pin passes longitudinally between the slot of the floating hinge 6 and the end of the connecting frame 7. In this design, two connecting frames 7 are provided on both sides of the intermediate float 1 to provide a rigid mounting base for the floating hinge 6, fix the hinge position, transmit the force between the floats, and prevent the connection from loosening and falling off; while the corresponding side floats 2 on both sides are respectively connected to floating hinges 6. One end of the floating hinge 6 has a slot that runs vertically through it for one end of the connecting frame 7 to be inserted, and a rotating pin runs longitudinally through it, thereby realizing vertical hinge rotation. A single intermediate float 1 and two side floats 2 constitute a buoyancy unit. As a basic modular component, it can realize the rapid splicing of multiple units, adapt to the needs of intercepting sewage in waters of different widths, and improve the versatility and installation efficiency of the equipment.

[0074] In this embodiment, to improve the articulation capability and achieve adaptive angle adjustment, the side float 2 has a groove at the position connecting the floating hinge 6. Two vertically arranged waterproof spring telescopic rods 3 are provided within the groove. The end of the floating hinge 6 away from the connecting frame 7 extends into the groove and connects between the two waterproof spring telescopic rods 3. In this design, the waterproof spring telescopic rod 3 itself has an inner cylinder and an outer cylinder. The inner cylinder can extend and retract under the action of the spring, and preferably, the inner cylinder can achieve axial deflection. The upper and lower sides of the floating hinge 6 are detachably connected to the inner cylinders of the two waterproof spring telescopic rods 3, respectively. This allows the floating hinge 6 to achieve vertical displacement and forward / backward deflection. Two waterproof spring telescopic rods 3 form a group, and multiple groups are evenly distributed to balance the force on the side floats 2, enhancing the resistance to water flow impact and improving adaptive balance stability. The waterproof spring telescopic rods 3 automatically and elastically extend and retract with the impact of waves and water flow, offsetting the influence of external forces and maintaining the balance of the equipment. The detachable design facilitates quick replacement after damage, reducing maintenance costs. The ends of the four waterproof spring telescopic rods 3 on the same side are connected to the side floats 2, which cooperate with the middle float 1 to increase the water surface contact area and improve floating stability. At the same time, it provides an installation carrier for the interception of dirt, clearing of blockages, and buoyancy adjustment components. For example, two sets of waterproof spring telescopic rods 3 on the side of one of the side floats 2 are respectively provided with first side connectors, which match and connect with second side connectors to realize the quick splicing and fixing of multiple buoyancy units. Two sets of waterproof spring telescopic rods 3 on the side of the other side float 2 are respectively provided with second side connectors, which cooperate with first side connectors to form a continuous interception belt, which is suitable for intercepting sewage in large-width water areas. The first side connector and the floating hinge 6 have the same structure, and the second side connector and the connecting frame 7 have the same structure, but the second side connector is connected to two waterproof spring telescopic rods 3 on the side float 2.

[0075] Example 4: Based on Example 3, Example 4 further provides a floating body unit capable of adjusting buoyancy, such as... Figure 6 As shown.

[0076] In this embodiment, since the buoyancy of traditional sewage interception equipment is not adjustable, the float is prone to sinking due to excessive water immersion. Therefore, in order to adjust the buoyancy of the float, the bottom of the float is also provided with a water inlet pipe 11 and a drain outlet 13 that are connected to its internal cavity. The water inlet pipe 11 and the drain outlet 13 are both connected to a miniature waterproof solenoid valve 23 at one end of the internal cavity of the float.

[0077] The float is also equipped with a miniature water pump, which is connected to the inlet pipe 11. In this design, each side float 2 has an inlet pipe 11 and a drain outlet 13 at its bottom. The water pump can introduce external water into the side float 2, and the drain outlet 13 can be used to adjust the water volume inside the float, thus precisely controlling the buoyancy. The drain outlet 13 is located at the bottom of each side float 2 opposite to the inlet pipe 11 to drain excess water from the float. This, together with the inlet pipe 11, completes the buoyancy control and prevents the float from sinking due to excessive water immersion. A protective filter screen 12 is detachably installed at one end of the inlet pipe 11 outside the side float 2 to intercept water debris and prevent blockage of the inlet pipe 11, ensuring unobstructed buoyancy control. The detachable design facilitates cleaning and maintenance. Secondly, the tops of both the inlet pipe 11 and the outlet 13 extend into the interior of the side float 2, allowing water to enter and exit the float and providing a flow channel for buoyancy adjustment. Miniature waterproof solenoid valves 23 are installed at the tops of both the inlet pipe 11 and the outlet 13, automatically controlling the pipe flow based on sensor signals to achieve intelligent automatic buoyancy adjustment without manual operation. Two miniature water pumps can also be installed inside the side float 2, connected to the inlet pipe 11 and the outlet 13 respectively, to pump and discharge water. Furthermore, electrode-type immersion sensors 24 are installed at the top edges of the rear ends of both side floats 2 to monitor the immersion depth and water level in real time, transmitting signals to the solenoid valves to trigger buoyancy adjustment and ensure safe floating of the equipment.

[0078] Installation steps and working principle of this solution:

[0079] S1: Equipment Assembly and Water Deployment. The intermediate float 1 and the side float 2 are precisely connected through the connecting frame 7 and the floating hinge 6. Waterproof spring telescopic rods 3 are installed in sequence to form a complete buoyancy unit. The barrier filter 5 is firmly installed at the bottom of the float through the filter structure installation piece 22. The filter counterweight 501 is added to ensure that the filter is vertical underwater. The assembled buoyancy unit is smoothly deployed to the target sewage interception area. The first side connector and the second side connector are used to complete the seamless splicing of multiple units. A continuous interception belt is built according to the width of the water area to complete the initial deployment of the equipment.

[0080] S2: After the self-balancing adaptive adjustment equipment is submerged in water, the waterproof spring telescopic rod 3, combined with the flexible connection characteristics of the floating hinge 6, automatically extends and adjusts according to the impact force of the water flow and the amplitude of wave fluctuations on site, and corrects the relative position of the middle float 1 and the side float 2 in real time, maintaining the overall buoyancy and attitude balance of the equipment. The electrode-type water immersion sensor 24 continuously collects the water immersion data of the float and provides real-time feedback on the floating status of the equipment, ensuring that the equipment floats stably at the designated position on the water surface.

[0081] S3: The interception operation starts and the horizontal propeller 16 automatically adjusts its speed according to the on-site water flow speed. The faster the water flow speed, the higher the rotation speed of the horizontal propeller 16. The active conical tooth 17 and the driven conical tooth 18 mesh and transmit power synchronously to the vertical propeller 15, driving it to rotate at high speed. The vertical propeller 15 is set vertically to generate an upward thrust, which drives the crossbar 14 to overcome its own weight and move upward along the guide rod 10. The permanent magnet 21 on the crossbar 14 and the strong magnetic metal 9 on the surface of the barrier filter 5 are continuously attracted, causing the barrier filter 5 to shake slightly, initially preventing garbage from adhering and clogging. Under the action of the filter counterweight 501, the barrier filter 5 remains vertically deployed, comprehensively intercepting pollutants such as garbage, aquatic plants, and debris in the water, and stably completing the water conservancy interception operation.

[0082] S4: Automatic Cleaning of the Filter Screen When debris adheres to the surface of the filter screen 5 and causes blockage, the water flow is obstructed, resulting in a decrease in water flow speed. The speed of the horizontal propeller 16 decreases accordingly, and the speed of the vertical propeller 15 decreases simultaneously. The upward thrust gradually decreases, and the horizontal bar 14 cannot overcome its own weight and falls back down along the guide bar 10. The horizontal bar 14 drives the scraper to scrape downward against the surface of the filter screen 5. At the same time, the attraction between the permanent magnet 21 and the strong magnetic metal 9 continuously drives the filter screen to shake, shaking off the blockage in the filter screen pores. Together with the scraper, the filter screen 5 is thoroughly cleaned. No manual intervention is required throughout the process, keeping the filter screen clear and ensuring that the interception operation is carried out continuously and efficiently.

[0083] S5: Intelligent drainage and overflow control electrode-type water immersion sensor 24 monitors the water immersion status of side float 2 in real time. When it detects that the float is over-immersed and the buoyancy is insufficient, it immediately triggers the micro waterproof solenoid valve 23 to open automatically. The water inlet pipe 11 and the drain outlet 13 work together to quickly drain the excess water inside the float and accurately adjust the buoyancy of the float to the standard state. The protective filter screen 12 at the bottom of the water inlet pipe 11 continuously intercepts debris to avoid pipe blockage and always maintains stable buoyancy of the equipment.

[0084] S6: Finishing and Storage Maintenance After the interception operation is completed, turn off the horizontal propeller 16 and the vertical propeller 15, stop the interception and filter cleaning operation, disassemble the connection structure of each buoyancy unit in sequence, salvage the entire equipment out of the water, disassemble the barrier filter 5, waterproof spring telescopic rod 3 and other vulnerable and consumable parts, thoroughly clean the garbage and residue on the surface of the equipment and inside the filter, dry each part and store it in categories, and perform protective maintenance to prepare the equipment for the next reuse.

[0085] The usage method of this embodiment is as follows: First, the intermediate float 1 and the side float 2 are connected by the connecting frame 7 and the floating hinge 6, and the waterproof spring telescopic rod 3 is installed to form a complete buoyancy unit. The blocking filter 5 is fixed to the bottom of the float by the filter structure mounting piece 22, and the filter counterweight 501 is added to ensure that the filter is vertical underwater. Then, the assembled buoyancy unit is deployed to the target sewage interception area. The first side connector and the second side connector are used to complete the splicing of multiple units to form a continuous sewage interception belt. After the equipment is submerged in water, the waterproof spring telescopic rod 3 and the floating hinge 6 automatically extend and adjust according to the water flow impact force and wave amplitude to maintain the overall balance of the equipment. The electrode-type water immersion sensor 24 continuously monitors the water immersion status of the float to ensure stable floating. During the sewage interception operation, the horizontal propeller 16 adapts to the water flow speed. The rotation speed should be adjusted so that the vertical propeller 15 can be driven to rotate through the meshing of the active conical tooth 17 and the driven conical tooth 18. The vertical propeller 15 drives the horizontal bar 14 to rise against its own weight. The permanent magnet 21 and the strong magnetic metal 9 magnetically attract each other, causing the barrier filter 5 to shake to prevent clogging. The barrier filter 5 continuously intercepts pollutants in the water. When the filter is clogged and the water flow speed decreases, the thrust of the vertical propeller 15 decreases, and the horizontal bar 14 falls due to its own weight, driving the cleaning scraper to complete the cleaning of the filter. When the electrode-type water immersion sensor 24 detects that the float is immersed in too much water, it triggers the opening of the miniature waterproof solenoid valve 23. The water inlet pipe 11 and the drain outlet 13 are linked to adjust the buoyancy of the float. The salvage equipment is disassembled, and the barrier filter 5, waterproof spring telescopic rod 3 and other components are disassembled and cleaned. After drying, they are sorted and stored to ensure that the equipment can be used repeatedly and stably.
