Description

Technical Field

[0001] This application relates to the field of water intake device technology, and in particular to an adaptive water level water intake device. Background Technology

[0002] Water intake devices that penetrate dikes are subject to multiple effects from water level fluctuations, water flow impacts, and equipment operation vibrations. These effects can lead to stress concentration in pipelines and fatigue damage at connection points. Furthermore, the vibrations can be transmitted to the dike structure, causing uneven settlement and seepage failure, which in turn threatens the safety of the entire water conservancy project.

[0003] Current suspended water intake devices typically employ a combination of a single-rod buoy and a rigid pipe. The buoy can only rise and fall in one direction, making it prone to stress concentration under the impact of wind, waves, and water flow, leading to twisting and breakage at the connection points. At the same time, the rigid pipe cannot adapt to the dynamic displacement of the buoy, causing vibrations to be directly transmitted to the steel pipe penetrating the dike and the facilities on the shore, resulting in weld cracking and damage to the seepage prevention layer.

[0004] To achieve vibration reduction for pipelines passing through dikes, some current pipelines use either a single flexible joint or a rigid structure. Flexible joints can only attenuate local vibrations and are insufficient to prevent vibrations from being transmitted to the bank, and they cannot adapt to the vertical displacement of the pontoons as the water level rises; while rigid pipelines can provide support, their damping is insufficient, and under strong vibration conditions, they are prone to uneven deformation of the dike and pipeline, leading to seepage failure. Summary of the Invention

[0005] This application aims to address at least one of the technical problems existing in the prior art. To this end, this application proposes an adaptive water level intake device, which can solve the problems of poor vibration reduction effect, limited displacement, structural damage caused by vibration transmission in traditional suspended water intake devices, as well as the single connection method of the pipeline through the dike, which cannot adapt to complex working conditions.

The water inlet component is disposed on the inlet float and includes a power component for pumping water into the inlet float. The inlet float and the counterweight float are movably connected to the guiding component, the guiding component being used to guide the inlet float and the counterweight float to move vertically to adapt to different water level heights.

[0007] According to some embodiments of this application, the first flexible tube and the second flexible tube are layered damping structures, the inner layer of the layered damping structure includes a wear-resistant layer, the outer layer of the layered damping structure includes a protective layer, and a variable damping layer is included between the wear-resistant layer and the protective layer; The variable damping layer is filled with magnetorheological fluid so that the variable damping layer can automatically adjust its damping characteristics according to the vibration frequency of the water flow.

[0008] According to some embodiments of this application, the magnetorheological fluid includes magnetic particles, a base fluid, and additives.

[0009] According to some embodiments of this application, the outer surface of the section of the rigid pipe penetrating the embankment is covered with a cushion layer, and the outer surface of the cushion layer is covered with a water-stop protective layer, which is used to adhere to the embankment concrete. The material of the padding layer includes at least polyurethane, and the material of the waterproofing bladder protective layer includes at least rubber.

[0010] According to some embodiments of this application, the rigid tube is provided with a support for supporting the rigid tube. The support includes a fixed body, a hydraulic damper, and a vibration damping component. The fixed body contacts and supports the rigid tube through the vibration damping component. The hydraulic damper is disposed on the fixed body and is used to support the rigid tube.

[0011] According to some embodiments of this application, the water inlet float is provided with protrusions, each of the protrusions protruding from the surface of the water inlet float, and the area of ​​the water inlet float with the protrusions is sprayed with wear-resistant hydrophobic paint, the protrusions and the wear-resistant hydrophobic paint forming a water film to isolate mud and sand particles.

[0012] According to some embodiments of this application, the water inlet assembly further includes a water inlet linked to the water inlet float, the water inlet being covered with a filter screen, the filter screen being used to filter out mud and sand particles in the water; When the water level in the area where the inlet float is located changes, the inlet float, together with the filter screen, moves vertically, and a relative shear force is generated between the filter screen and the water flow, so that the mud and sand attached to the filter screen are stripped off by the water flow.

[0013] According to some embodiments of this application, the guiding assembly includes a guide rail and a rotary chuck that mesh with each other, and the inlet float and the counterweight float are both connected to the guide rail via the rotary chuck; When the rotary chuck rotates, it can travel along the guide rail to drive the inlet float and / or the counterweight float to move vertically along the guide rail.

[0014] According to some embodiments of this application, the guide rail has a semi-circular toothed chain arranged on one side for contacting the rotary chuck, and the surface of the rotary chuck is provided with a semi-circular recess that can be embedded in the semi-circular toothed chain.

[0015] According to some embodiments of this application, the guide rail is provided with a hollow sand-clearing groove. When the rotating chuck rotates, the rotating chuck can drive the water flow to form a rotating water wave to wash away the mud and sand on the surface of the guide rail.

[0026] like Figure 1 As shown in the figure, this application provides an adaptive water level intake device. The adaptive water level intake device is mainly used in the scenario of water intake through dikes. It solves the problem of existing suspended water intake devices causing pipeline fatigue damage and silt adhesion and blockage due to vibration transmission under the conditions of high sediment and strong water flow during the flood season. At the same time, it adapts to the coordinated operation of water level fluctuations and shore facilities.

[0027] The adaptive water level intake device includes a water conveyance component, a water intake component, an inlet component, and a guide component. The inlet component provides power to the water, driving it into the intake component. The water then flows further along the conveyance component, ultimately reaching the shore-end pipeline to complete the water intake process. Simultaneously, the guide component guides the intake component's vertical movement, enabling it to adapt to changes in water level and water flow impact.

[0028] The water conveyance assembly includes a first flexible pipe 101, a rigid pipe 102, and a second flexible pipe 103 that are interconnected, with the rigid pipe 102 located between the first flexible pipe 101 and the second flexible pipe 103. The first flexible pipe 101 is used to connect to the water intake assembly, and the second flexible pipe 103 is used to connect to the shore-end pipeline. When water flows into the water conveyance assembly, the water flows sequentially to the first flexible pipe 101, the rigid pipe 102, and the second flexible pipe 103, and is finally delivered to the shore-end pipeline.

[0029] Furthermore, the first flexible tube 101 and the second flexible tube 103 are mainly made of high-damping rubber material and have built-in spiral reinforcing ribs, while the rigid tube 102 is made of corrosion-resistant alloy material. Since the water intake component of this application floats on the water surface, it exhibits dynamic displacement under the influence of changes in water level and water flow impact.

[0030] In this scenario, the first flexible pipe 101 can adapt to the dynamic displacement of the water intake component through adaptive deformation, thereby acting as a motion buffer and attenuating vibration at its source. Simultaneously, the adaptive deformation of the first flexible pipe 101 prevents the rigid pipe 102 from undergoing significant displacement, facilitating its stable load-bearing function. However, the rigid pipe 102 may still experience small displacements and vibrations under the influence of water flow. The second flexible pipe 103, based on the first flexible pipe 101, can further block the transmission of vibration to the shore-end equipment through adaptive deformation. This allows the vibration generated by the water flow to be gradually attenuated through the first flexible pipe 101, the rigid pipe 102, and the second flexible pipe 103, preventing vibration-induced pipe fatigue damage and also preventing vibration from affecting the normal operation of the shore-end equipment.

[0031] In addition, the first flexible pipe 101, the rigid pipe 102 and the second flexible pipe 103 are detachably connected, which makes it easy for staff to freely increase or decrease the number of flexible pipes and rigid pipes 102 according to the specific water conditions, thereby improving the flexibility and versatility of the adaptive water level intake device of this application.

[0032] Furthermore, the water intake assembly includes an inlet float 201 and a counterweight float 202, both of which float on the water surface. The inlet float 201 is connected to the first flexible pipe 101 and can guide water flow into the first flexible pipe 101, while the counterweight float 202 can serve as a counterweight.

[0033] Specifically, the outer shells of the inlet pontoon 201 and the counterweight pontoon 202 are both made of carbon fiber reinforced composite material, and the surfaces of the inlet pontoon 201 and the counterweight pontoon 202 are coated with a nano-ceramic anti-corrosion coating to adapt to waters with high siltation and high salinity.

[0034] Furthermore, the water inlet assembly is disposed on the water inlet float 201, and the water inlet assembly includes a power component 301. Specifically, the power component 301 is mounted on the water inlet float 201 and located at the geometric center of the water inlet float 201, and the power component 301 includes a water pump. It is understood that the power component 301 is capable of drawing water and providing the power for the water flow, so that the powered water flow enters the water inlet float 201 and reaches the first flexible pipe body 101 of the water delivery assembly through the water inlet float 201.

[0035] Furthermore, the guiding component is used to guide the water inlet float 201 and the counterweight float 202 to move in the vertical direction, which can, to a certain extent, prevent the water inlet float 201 and the counterweight float 202 from swaying horizontally under the influence of water flow, thereby reducing the vibration of the device.

[0036] Specifically, the guiding assembly includes a support component 401, which is formed as a frame structure and anchored to the bottom of the riverbed or the edge of the water area. Inlet buoys 201 and counterweight buoys 202 are embedded inside the support component 401 and are capable of vertical movement within the support component 401 to adapt to changes in water level.

[0037] The contents of this application are described in detail below with reference to specific embodiments. It should be noted that the following description is merely illustrative and not a specific limitation of this application.

[0038] like Figure 2 As shown, in some embodiments, both the first flexible tube 101 and the second flexible tube 103 adopt a layered damping structure. It can be understood that the layered damping structure includes several layered structures.

[0039] The layered damping structure comprises an inner layer, an outer layer, and a middle layer. The inner layer includes a wear-resistant layer 104, which contacts the water flow inside the first flexible tube 101 and the second flexible tube 103, ensuring the structural strength of the first and second flexible tubes 101 under frequent water flow impacts. The outer layer includes a protective layer 105, which protects the first and second flexible tubes 101 and 103 when objects in the external environment collide with them.

[0040] Furthermore, the middle layer of the layered damping structure includes a variable damping layer 106, which is located between the wear-resistant layer 104 and the protective layer 105. The variable damping layer 106 is the core of the layered damping structure. The variable damping layer 106 is filled with magnetorheological fluid, which enables the variable damping layer 106 to automatically adjust its damping characteristics according to the vibration frequency of the water flow, thereby improving the adaptability of the first flexible tube 101 and the second flexible tube 103 and reducing the vibration of the first flexible tube 101 and the second flexible tube 103.

[0041] Specifically, the inner wear-resistant layer 104 is mainly made of nitrile rubber with a thickness of about 3 mm; the middle variable damping layer 106 has a thickness of about 6 mm; and the outer protective layer 105 is mainly made of polyethylene with a thickness of about 2 mm.

[0042] In some embodiments, the magnetorheological fluid includes magnetic particles, a base fluid, and additives. The magnetic particles comprise 67% to 73% of the magnetorheological fluid, the base fluid comprises 24% to 30%, and the additives comprise 0% to 6%.

[0043] Specifically, the magnetic particles account for 70% of the magnetorheological fluid, the base fluid accounts for 27% of the magnetorheological fluid, and the additives account for 3% of the magnetorheological fluid.

[0044] The magnetorheological fluid is the working medium inside the variable damping layer 106, enabling the variable damping layer 106 to automatically adjust its damping characteristics according to the vibration frequency of the water flow. When the vibration frequency of the water flow is ≤5Hz, the magnetorheological fluid is in a low-damping state, with a relatively small attenuation effect on vibration; when the vibration frequency of the water flow is >5Hz, the magnetorheological fluid automatically switches to a high-damping state to efficiently attenuate vibrations of different frequencies.

[0045] like Figure 3 As shown, in some embodiments, the portion of the rigid pipe 102 that passes through the embankment is called the through-section, and the rigid pipe 102 contacts the embankment through this through-section. When the rigid pipe 102 vibrates, the vibration is transmitted between the through-section and the embankment, which can easily damage both the embankment and the rigid pipe 102. Simultaneously, a certain degree of sealing is required between the through-section and the embankment to prevent water from seeping out along the gaps between them.

[0046] Therefore, the outer side of the section penetrating the embankment is wrapped with a cushion layer 107 and a water-stop protective layer 108. The cushion layer 107 is used to contact the section penetrating the embankment, and the water-stop protective layer 108 is used to contact the embankment concrete. The water-stop protective layer 108 can fit tightly into the embankment concrete and can adapt to the uneven settlement of the embankment.

[0047] Specifically, the material of the cushion layer 107 includes at least polyurethane, and the material of the water-stop protective layer 108 includes at least rubber, polyurethane, and rubber. The cushion layer 107 and the water-stop protective layer 108 work together to form a flexible, buffering, and self-adaptive seepage-proof composite protective structure.

[0048] like Figure 4 As shown, in some embodiments, the rigid tube 102 is equipped with a support 501, which, in addition to supporting the rigid tube 102, can also play a role in vibration reduction.

[0049] The support 501 includes a fixed body 502, a hydraulic damper 503, and a vibration damping component 504. The fixed body 502 is fixed in position and located at the bottom of the rigid pipe body 102. The vibration damping component 504 is located at the top of the fixed body 502 and contacts the rigid pipe body 102. Specifically, the vibration damping component 504 includes a spring, which can adapt to and mitigate the vibration of the rigid pipe body 102 through elastic deformation. Meanwhile, the hydraulic damper 503 is located inside the fixed body 502 and contacts the rigid pipe body 102. Operators can adjust the damping force of the hydraulic damper 503 according to the actual vibration amplitude, allowing the hydraulic damper 503 to adapt to and mitigate the vibration of the rigid pipe body 102, further attenuating the reverse vibration transmission of the shore-end equipment.

[0050] Therefore, the support 501 can work synergistically with the second flexible tube 103 to reduce vibration, greatly improving the system's vibration reduction and anti-interference capabilities.

[0051] like Figure 5 As shown, in some embodiments, the surface of the water inlet float 201 is provided with a plurality of protrusions 203, the protrusions 203 are circular in shape and protrude from the surface of the water inlet float 201.

[0052] Understandably, the surface of the inlet float 201 has an area with raised dots 203, resulting in a relatively large surface roughness, which facilitates the adhesion of the wear-resistant hydrophobic paint to this area. Specifically, the wear-resistant hydrophobic paint is applied to this area via a spraying process.

[0053] Furthermore, the protrusions 203 are arranged in a honeycomb pattern on the surface of the inlet float 201, with each honeycomb unit having a side length of approximately 12 mm and a height of 2 mm to 3 mm. In actual implementation, the height of the protrusions 203 can be set to 2.5 mm. Simultaneously, the contact angle of the wear-resistant hydrophobic paint coating is ≥110°, and the protrusions 203 at the bottom of the inlet float 201 form a thin water film with the wear-resistant hydrophobic paint to isolate sediment particles in the water.

[0054] Specifically, the thin water film formed by the protrusions 203 and the wear-resistant hydrophobic paint prevents sediment particles from directly contacting the inlet float 201. The sediment particles merely slide across the thin water film, thus preventing sediment from adhering and clogging the inlet float 201. At the same time, the inlet float 201 drives the water flow at its bottom edge to form a continuously rotating micro-vortex, causing sediment particles to move outward under the action of centrifugal force, achieving a non-contact state between sediment and the inlet float 201, further preventing sediment adhesion and clogging at the source.

[0055] In some embodiments, the water inlet assembly further includes a water inlet 302, which is linked to the water inlet float 201. When the water inlet float 201 moves with the water level, the water inlet float 201 also drives the water inlet 302 to move.

[0056] Furthermore, the inlet 302 is covered with a filter screen 303, which is used to filter out sediment particles in the water and prevent excessive sediment particles from entering the inlet float 201 along the inlet 302.

[0057] Specifically, the inlet float 201 can scrape and clean the filter screen 303 by moving vertically. When the water level in the area where the inlet float 201 is located changes, the inlet float 201 moves vertically along the guide assembly, causing the filter screen 303 to move upward or downward with the inlet float 201. Since the external water is relatively still or its flow velocity is much lower than the moving speed of the inlet float 201, a relative shear force is generated between the water flow and the filter screen 303. This relative shear force can scrape and peel off the mud and sand adhering to the surface of the filter screen 303. It can be understood that when the inlet float 201 moves upward, the filter screen 303 moves upward, and the water flow is relatively downward, washing the scraped mud and sand downward and away from the filter screen 303; when the inlet float 201 moves downward, the filter screen 303 moves downward, and the water flow is relatively upward, washing the scraped mud and sand upward and away from the filter screen 303. The "above" in this application refers to... Figure 1 and Figure 5 The X-axis direction in the diagram.

[0058] In addition, a flared mouth is provided at the port of the inlet 302, with an expansion angle of 15° to 20°, and the inner wall of the flared mouth is streamlined and polished to facilitate the flow of water into the inlet float 201.

[0059] like Figures 6 to 8 As shown, in some embodiments, the guiding assembly includes a guide rail 402 and a rotary chuck 403, which mesh with each other. When the rotary chuck 403 rotates, it can travel along the guide rail 402. The guide rail 402 is arranged vertically, meaning the rotary chuck 403 can be vertically adjusted along the guide rail 402.

[0060] Furthermore, both the inlet float 201 and the counterweight float 202 are connected to the guide rail 402 via a rotary chuck 403. When the inlet float 201 and the counterweight float 202 move with the change in water level, the rotary chuck 403 adjusts its position along the guide rail 402 by rotating, which ensures the smoothness of the position adjustment process and limits the movement of the inlet float 201 and the counterweight float 202 to the vertical direction.

[0061] like Figure 7 As shown, in some embodiments, the surface of the guide rail 402 is arranged with semi-circular toothed chains 404, which are specifically formed as a plurality of semi-circular protrusions arranged along the guide rail 402. Meanwhile, the rotary chuck 403 is generally circular, and the edge of the circular rotary chuck 403 is evenly distributed with a plurality of semi-circular recesses. The semi-circular protrusions can be inserted into the semi-circular recesses, thereby achieving engagement between the guide rail 402 and the rotary chuck 403.

[0062] Furthermore, the semi-circular protrusions and recesses ensure that the engagement process between the guide rail 402 and the rotating chuck 403 is a line-contact rolling process with a low coefficient of friction. This improves the smoothness of the lifting and lowering of the inlet float 201 and the counterweight float 202, effectively reducing energy consumption and wear between them. Simultaneously, the uniform stress distribution of the semi-circular protrusions and recesses avoids stress concentration under alternating loads, unlike other shapes, thus improving the fatigue life of the structure. Even if the inlet float 201 and the counterweight float 202 experience slight swaying, they can still maintain effective engagement, enhancing the system's adaptability under complex hydrological conditions. In addition, compared to other shapes such as sharp-angled teeth, the semi-circular protrusions and recesses are less prone to snagging debris, and sediment is less likely to accumulate in the grooves, ensuring the normal operation of the guiding components in high-sediment waters.

[0063] like Figure 7 and Figure 8 As shown, in some embodiments, the central region of the guide rail 402 is provided with a vertically extending hollow sand-cleaning groove 405, and the semi-circular toothed chain 404 is located on opposite sides of the hollow sand-cleaning groove 405.

[0064] Furthermore, as the rotating chuck 403 moves up and down along the guide rail 402 by rotation, it drives the water flow to form directional rotating water waves. These rotating water waves continuously wash away the mud and sand in the environment into the hollowed-out sand cleaning trough 405. At the same time, the mud and sand entering the hollowed-out sand cleaning trough 405 can continuously fall under their own gravity, preventing the mud and sand from adhering to the surface of the guide rail 402 and preventing the guide rail 402 and the rotating chuck 403 from jamming during transmission.

[0065] In some embodiments, the water intake assembly, water inlet assembly, and water delivery assembly are quickly connected via standard flanges to form a stable levitation and vibration reduction system, which also helps to ensure the fixation and coordination of each component. It is understood that sealing rings must be installed in each connection area to prevent water leakage. At the same time, the flange connection allows for detachable connection of the water intake assembly, water inlet assembly, and water delivery assembly, improving the flexibility and transportation convenience of the device.

[0066] Furthermore, the interior of the counterweight float 202 can be equipped with a buoyancy adjustment chamber that can be inflated and deflated, and the air pressure inside the chamber can be adjusted by a micro air pump to achieve dynamic fine-tuning of buoyancy.

[0067] In addition, when the water conveyance component has a long distance to cross the dike, the rigid pipe 102 can be set in sections, with each section being 5 meters long, and the rigid pipe 102 sections can be sealed and connected to ensure the structural stability and seepage prevention effect when crossing the dike over a long distance.

[0068] In practical implementation, the adaptive water level intake device includes a water conveyance component, an intake component, an inlet component, and a guiding component. Its structure is clear and its functions are coordinated. The water conveyance component can freely configure the number of flexible pipe sections according to the water conditions, and the entire system adopts a modular design, which facilitates prefabrication and rapid on-site assembly, significantly reducing construction complexity. Through the coordinated work of the first flexible pipe body 101, the rigid pipe body 102, and the second flexible pipe body 103, the water conveyance component achieves multi-stage vibration attenuation—front-end buffering, mid-end load bearing, and rear-end vibration reduction—solving the problems of easy deformation of fully flexible pipes and easy breakage of fully rigid pipes. It attenuates vibration transmission at the source, ensuring both continuous water intake and water quality stability, while also improving the fatigue life and operational reliability of the pipeline crossing the dike. Furthermore, the intake component and the guiding component work together to achieve smooth vertical displacement and omnidirectional disturbance adaptation of the inlet float 201 and the counterweight float 202, avoiding the stress concentration problem of traditional single-rod guiding. Meanwhile, the array of protrusions 203 at the bottom of the inlet float 201, combined with the wear-resistant hydrophobic paint, creates a micro-vortex effect, fundamentally solving the problem of sediment adhesion and blockage. Furthermore, the funnel-shaped structure of the inlet 302 optimizes the water intake flow pattern and improves water delivery efficiency.
