Description

Technical Field

[0001] This application relates to the technical field of dredging equipment for water conservancy projects, and in particular to a sluice gate dredging device. Background Technology

[0002] As a core facility of water conservancy projects, sluice gates are mainly used for regulating water levels, controlling water flow, flood control and drainage, and irrigation water supply. Their operational status directly affects the normal functioning of water conservancy projects. However, sluice gates are often underwater or in humid environments, where silt and debris in the water flow easily accumulate at the bottom of the gate chamber and at the gate opening, forming silt. If this silt is not removed in time, it can lead to a decrease in the sluice gate's flow capacity, obstruction of gate opening and closing, corrosion and damage to the gate structure, and in severe cases, even cause safety hazards such as gate chamber collapse and turbulent water flow. Therefore, sluice gate dredging is an important part of the daily maintenance of water conservancy projects.

[0003] Patent document CN115288224B discloses a self-moving sluice gate dredging device, including a hull with pontoons fixed on both sides of the hull, a power unit inside the hull, a processing box in front of the power unit, and a forward impeller on the back of the hull. The device is characterized by a bucket assembly at the front of the hull, with a cleaning electric telescopic rod on one side of the bucket assembly. One end of the cleaning electric telescopic rod is hinged to one side of the bucket body, and the other end is hinged to one wall of the hull. A transmission assembly is located at the top of the hull, and a tilting assembly is located above the processing box.

[0004] Existing sluice gate dredging equipment suffers from numerous technical deficiencies in practical applications, failing to meet the demands for efficient, safe, and convenient dredging. Specific shortcomings include: First, the lack of real-time water flow velocity detection and collapse-linked protection structures. Sudden changes in water flow velocity can easily cause silt collapses, and the impact force generated by these collapses can lead to equipment displacement, tilting, or even damage, making timely and stable fixation impossible. Second, the bearings of the dredging components are prone to clogging with mud during collapses. Due to the lack of targeted cleaning structures, this results in dredging rollers becoming stuck and rotating poorly, affecting dredging efficiency and even damaging transmission components. Third, the silt generated during dredging is not drained, containing a large amount of wastewater and being bulky, significantly occupying equipment storage space and requiring frequent silt discharge, thus reducing the continuity of dredging operations.

[0005] To address the shortcomings of existing technologies, there is an urgent need for a sluice gate dredging device that integrates real-time water flow detection, collapse linkage fixation, self-cleaning of dredging components, sludge dewatering, and synchronous linkage of multiple components. By optimizing the structural design and synchronous transmission logic, this device can solve many defects of existing equipment, improve dredging efficiency and equipment stability, save sludge storage space, reduce safety hazards and operating costs, and meet the high-efficiency and safe requirements of sluice gate dredging. Summary of the Invention

[0017] In summary, this application includes at least one of the following beneficial technical effects: 1. Real-time water flow detection and landslide-linked fixing enhance equipment safety: The flow velocity is detected in real time by a flow velocity sensor component. Combined with the first synchronous transmission mechanism, the water flow detection and fixing components are linked. When a sudden change in water flow velocity causes a silt landslide, the fixing components can be quickly activated, and the fixing piles are inserted into the bottom soil to stabilize the equipment and prevent it from shifting, tilting, or being damaged. This solves the technical defects of existing equipment that are easily damaged by landslides and reduces the safety hazards of dredging operations. At the same time, the vibration cleaning and sealing protection of the protective cover ensures accurate flow velocity detection and improves the reliability of landslide early warning.

[0018] 2. Dual cleaning components work together to solve the problem of sludge roller jamming: The first and second cleaning components work together to thoroughly clean the bearing parts of the sludge cleaning component. The rotating spray head sprays and washes away the sludge, and the cleaning scraper scrapes away residual sludge, effectively preventing sludge from adhering and clumping, which can cause the sludge cleaning roller to jam. This ensures the continuous and stable operation of the sludge cleaning component, improves sludge cleaning efficiency, and reduces component wear and maintenance costs. The sealing protection of the first rubber seal further protects the transmission components of the cleaning component. Attached Figure Description

Detailed Implementation

[0021] Example 1 The following is in conjunction with the appendix Figures 1-15 The first embodiment of this application will be described in further detail.

[0022] A sluice gate dredging device includes: a dredging device body 2, which provides an integrated installation and sealed working cavity for each component, protecting the internal parts from sludge and sewage erosion and ensuring the orderly operation of each component; a crawling component 7, installed at the bottom of the dredging device body 2, which adopts a tracked or wheeled crawling structure to drive the device to move flexibly in complex areas such as the bottom of the sluice gate and the gate chamber, adapting to different dredging scenarios; a camera module 3, installed on the right side of the dredging device body 2, used to capture real-time images of the dredging operation area and feed them back to the central control module 1, facilitating remote monitoring of the operation status by the operator; and a central control module 1, installed on the front side of the dredging device body 2, electrically connected to each component, used to receive data feedback from the flow velocity sensor component, water level detector 50, etc., and control the start / stop and operating parameters of each component to achieve intelligent control of the dredging operation. The dredging component, located at the front of the dredging equipment body 2, is the core dredging component. It is used to scrape and break the silt at the bottom of the sluice gate, perform dredging operations, and guide the silt into the subsequent adsorption component. The adsorption component, located on top of the dredging component, is used to adsorb, transport, and collect the sludge generated by the dredging component, preventing sludge from accumulating in the dredging area and ensuring the continuous operation of the dredging work. The flow velocity sensing component is located on the right side of the dredging equipment body 2. It is used to detect the water flow velocity in the sluice gate in real time and feed the detection data back to the central control module 1 to provide data support for landslide early warning and equipment fixation. The first cleaning component has two parts, both of which are mounted on the sludge removal component. They are used to spray clean water to clean the sludge removal rollers 12, bearings 29 and other parts of the sludge removal component to prevent sludge from adhering and clumping. The second cleaning component has two parts, which are respectively mounted on the two first cleaning components. It is used to assist in cleaning the sludge remaining on the surface of the sludge removal component by mechanical scraping, and works with the first cleaning component to achieve comprehensive cleaning. The fixing component is assembled on the body 2 of the dredging equipment. It is used to quickly extend the fixing pile 25 into the bottom soil when the water flow velocity changes suddenly and causes the silt to collapse, so as to stabilize and fix the body 2 of the dredging equipment and prevent the equipment from shifting, tilting or being damaged. The vibration component, located inside the main body 2 of the dredging equipment, is used to vibrate and drain the sludge collected by adsorption, separate the sewage in the sludge, reduce the volume of sludge, save equipment storage space, and improve the continuity of dredging. The first synchronous transmission mechanism is located behind the flow velocity sensing component and is used to synchronously drive the flow velocity sensing component and the fixed component to realize the linkage between water flow detection and equipment fixation, thereby improving the response speed of landslide protection. The second synchronous transmission mechanism is located in front of the dredging component. It is used to synchronously drive the vibration component and the dredging component to achieve coordinated operation of dredging and sludge draining, thereby improving overall work efficiency and reducing energy consumption.

[0023] In this embodiment, the dredging assembly includes a first rotating motor 24, two bearings 29, and a first rotating frame 5. The first rotating frame 5 is fixedly connected to the front side of the dredging equipment body 2, serving as the mounting carrier for the dredging assembly and providing stable support for other components. Two second rotating frames 31 are symmetrically connected on both sides of the first rotating frame 5 for mounting the bearings 29 and the dredging rollers 12. The two bearings 29 are respectively embedded in the central through holes of the two second rotating frames 31 to reduce the rotational friction of the dredging rollers 12 and ensure the smooth rotation of the dredging rollers 12. The dredging roller 12 rotates smoothly, with a dredging roller 12 mounted at the center point of the two bearings 29. The surface of the dredging roller 12 is equipped with wear-resistant scraping teeth for scraping and breaking up the silt at the bottom of the sluice gate. The silt inlet of the first rotating frame 5 is fixedly connected to a guide groove 4 to guide the silt scraped off by the dredging roller 12 to the adsorption component, preventing silt splashing. The first rotating motor 24 is installed on the rear side of the first rotating frame 5, and its output shaft is fixedly connected to the rear end of the dredging roller 12 to drive the dredging roller 12 to rotate at high speed and perform dredging operations. The two second rotating frames 31 and the two bearings 29 are symmetrically distributed around the transverse central axis of the first rotating frame 5 to ensure that the dredging roller 12 is evenly stressed and rotates smoothly. Two mudguards 6 are also fixedly connected to the front side of the dredging equipment body 2 to prevent sludge from splashing during collapse, avoiding sludge contamination of the mechanical parts and camera module 3 behind the equipment, and ensuring normal operation and clear monitoring of the operation.

[0024] Specifically, the central control module 1 controls the first rotating motor 24 to start. The output shaft of the first rotating motor 24 drives the sludge removal roller 12 to rotate at high speed around the center point of the two bearings 29. The wear-resistant scraping teeth on the surface of the sludge removal roller 12 scrape the silt at the bottom of the sluice gate, breaking up and scraping up the clumps of silt. The scraped silt, driven by the rotation of the sludge removal roller 12, is guided into the guide channel 4 of the sludge inlet of the first rotating frame 5, and then guided by the guide channel 4 to the adsorption component at the top to complete the sludge removal operation. The two symmetrically distributed second rotating frames 31 and bearings 29 ensure that the sludge removal roller 12 rotates smoothly and is subjected to uniform force, reducing shaking and wear during rotation. The mudguard 6 blocks splashed sludge in real time, protecting the components behind the equipment and preventing it from affecting the normal operation of the equipment and the camera module. The observation field of view is 3; at the same time, when the first rotating motor 24 drives the dredging roller 12 to rotate, the vibration component is driven to run through the second synchronous transmission mechanism to realize the synchronous linkage of dredging and sludge draining; the dredging roller 12 is made of high-strength wear-resistant steel, and the scraping teeth on the surface are hardened to enhance wear resistance and adapt to the scraping of hard sludge and debris at the bottom of the sluice gate; the bearing 29 is a waterproof sealed bearing to prevent sewage and sludge from entering the bearing 29, causing jamming or damage, and extending its service life; the first rotating frame 5 and the second rotating frame 31 are both welded from thickened steel plates, with a stable structure that can withstand the impact force during the dredging process; the mudguard 6 is made of corrosion-resistant and non-stick material, and the surface is smoothed to reduce sludge adhesion and facilitate subsequent cleaning.

[0025] In this embodiment, the adsorption assembly includes a sludge inlet check valve 28 and a conduit 11. The sludge inlet check valve 28 is installed at the inlet of the guide channel 4 to control the sludge to enter the adsorption assembly in one direction, preventing the adsorbed sludge from flowing back into the guide channel 4 and ensuring smooth sludge transmission. A second support plate 27 is installed inside the sludge removal equipment body 2 to fix the output frame 9 and the first sludge pump 10, providing stable support. The output frame 9 is fixedly installed at the bottom of the second support plate 27 to fix the first sludge pump 10 and enhance the installation stability of the first sludge pump 10. The first sludge pump 10 is fixedly installed at the top of the output frame 9 as the power source for sludge adsorption and transmission, used to generate negative pressure to adsorb the sludge in the guide channel 4. The two ends of the conduit 11 are fixedly connected to the inlet of the first sludge pump 10 and the outlet of the sludge inlet check valve 28, respectively, to form a sludge transmission channel, ensuring smooth sludge adsorption and transmission, and transporting the adsorbed sludge to the hopper 8 of the vibration assembly for draining treatment.

[0026] Specifically, while the dredging components are operating, the central control module 1 controls the start of the first sludge pump 10. The first sludge pump 10 generates negative pressure, which adsorbs the sludge in the guide channel 4 through the conduit 11 and the sludge inlet check valve 28. Under the action of negative pressure, the sludge in the guide channel 4 enters the first sludge pump 10 through the sludge inlet check valve 28 and the conduit 11 in sequence. After being pressurized by the first sludge pump 10, it is transported to the hopper 8 of the vibrating component, completing the adsorption and transfer of sludge. The sludge inlet check valve 28 effectively prevents the adsorbed sludge from flowing back, ensuring the unidirectional and smooth transfer of sludge. The second support plate 27 cooperates with the output frame 9 to provide stable support for the first sludge pump 10, avoiding the vibration generated by the first sludge pump 10 during operation from affecting the adsorption effect and equipment stability. The adsorption component and the dredging component operate synchronously to ensure that the sludge generated during dredging is adsorbed in a timely manner, avoiding sludge accumulation and improving the continuity of dredging operations.

[0027] In this embodiment, the flow velocity sensing component includes a flow velocity detection module 20 and multiple first reset springs 45. The flow velocity detection module 20 is fixedly installed on the front side of the dredging equipment body 2 and is used to detect the water flow velocity in the sluice gate in real time. It converts the detection data into an electrical signal and feeds it back to the central control module 1 to provide data support for landslide early warning. A fixed frame 19 is fixedly connected to its front side for installing components such as the protective cover 44 and the first reset springs 45, providing stable support. The protective cover 44 is slidably connected inside the fixed frame 19 to seal and protect the flow velocity detection module 20, preventing underwater sludge and debris from entering the flow velocity detection module 20 and affecting the detection accuracy or damaging the module. A second rubber seal 47 is fixedly connected to the outer periphery of the protective cover 44, and the second rubber seal 47 is in close contact with the inner wall of the fixed frame 19, which enhances the sealing performance of the protective cover 44 and further improves the protective effect. A first guide sleeve 48 is sleeved around the periphery of multiple first return springs 45. The first guide sleeve 48 is used to limit the extension and retraction direction of the first return springs 45 and prevent the first return springs 45 from being twisted and deformed under force. The two ends of each first return spring 45 and the first guide sleeve 48 are fixedly connected to the protective cover 44 and the housing of the flow rate detection module 20, respectively, so as to realize the elastic reset and smooth sliding of the protective cover 44. A first rotating shaft 21 is rotatably installed on the rear side of the fixed frame 19, which is used to transmit power to the first cam 46. A first cam 46 is fixedly connected to the front side of the first rotating shaft 21. The first cam 46 is in contact with the inner wall of the protective cover 44 and is used to drive the protective cover 44 to vibrate, shake off the sludge attached to the surface of the protective cover 44, and prevent the sludge from blocking the protective cover 44 and affecting the detection accuracy of the flow rate detection module 20.

[0028] Specifically, during the dredging operation, the flow velocity detection module 20 continuously monitors the water flow velocity inside the sluice gate and feeds the detection data back to the central control module 1 in real time. Simultaneously, the first synchronous transmission mechanism drives the first rotating shaft 21 to rotate, which in turn drives the first cam 46, fixedly connected to the front, to rotate at high speed. Due to the eccentric design of the first cam 46, it continuously abuts against the inner wall of the protective cover 44 during rotation, pushing the protective cover 44 to slide along the inside of the fixed frame 19. Multiple first return springs 45 then perform reciprocating stretching and compression movements, providing elastic return power to the protective cover 44 and ensuring stable and continuous reciprocating vibration. The reciprocating vibration of the protective cover 44 can shake off the sludge adhering to its surface, preventing sludge from obscuring the protective cover 44 and ensuring that the flow velocity detection module 20 can accurately detect the water flow velocity. The second rubber seal 47 ensures the seal between the protective cover 44 and the fixed frame 19, preventing underwater sludge and sewage from entering the fixed frame 19 and protecting the flow velocity detection module 20. When the flow velocity is detected... When module 20 detects a sudden change in water flow velocity exceeding a preset threshold, the central control module 1 determines it as a collapse warning, controls the first synchronous transmission mechanism to increase power output, and quickly starts the linkage fixing components to fix the equipment. The flow velocity detection module 20 uses a high-precision underwater flow velocity sensor with a wide detection range and high accuracy, adapting to the detection needs of different water flow velocities in the sluice gate. The protective cover 44 is made of high-strength transparent material, which does not affect the detection field of the flow velocity detection module 20, and can also play an effective protective role. The second rubber seal 47 is made of corrosion-resistant and wear-resistant rubber material with good elasticity and excellent sealing performance, suitable for long-term underwater use. The first return spring 45 is made of stainless steel spring, which is corrosion-resistant and has good elasticity, extending its service life. The first guide sleeve 48 is made of smooth and wear-resistant material, and the mating surfaces with the first return spring 45 and the protective cover 44 are lubricated to ensure that the protective cover 44 slides smoothly without jamming. The first cam 46 is made of wear-resistant material with a smooth surface treatment to reduce frictional wear with the protective cover 44.

[0029] In this embodiment, the first cleaning component on the front side includes multiple rotating connectors 40. A water tank 51 is installed inside the sludge removal equipment body 2 to store clean water required for spray cleaning and to provide a water source for the first cleaning component. A one-way valve 49 is installed at the inlet of the water tank 51 to control the one-way entry of clean water into the water tank 51, preventing the clean water in the water tank 51 from flowing back, and facilitating the replenishment of clean water into the water tank 51. A first one-way valve 52 is installed at the outlet to control the one-way output of clean water in the water tank 51 to the first water pump 30, preventing the clean water from flowing back into the water tank 51 and ensuring a stable spray water supply. A water level detector 50 is fixedly installed on the front side of the water tank 51 to monitor the water level in the water tank 51 in real time and feed the water level data back to the central control module 1. When the water level is lower than a preset threshold, the operator is reminded to replenish clean water to avoid the failure of spray cleaning due to lack of water. A first water pump 30 is installed on the front side of the second rotating frame 31, serving as the power source for spray cleaning. It pressurizes the clean water in the water tank 51 and delivers it to the spray heads 32. The inlet of the first water pump 30 is connected to the outlet of the first one-way valve 52 via a hose. A distributor 36 is installed at the outlet to distribute the pressurized clean water to multiple spray heads 32, achieving uniform water supply. Multiple water inlets 39 are fixedly connected to the interlayer of the second rotating frame 31 for connecting the distributor 36. 6. The rotating connector 40 is used to transfer clean water. The connecting end of each rotating connector 40 is fixedly connected to the corresponding water inlet 39. The rotating end is fixedly connected to the spray head 32. The rotating connector 40 is used to realize the rotation of the spray head 32 and at the same time ensure that the clean water is delivered smoothly and without leakage. The multiple output ports of the diverter 36 are connected to the input ports of each water inlet 39 through hoses to form a clean water delivery channel, realize the uniform water supply for spray cleaning, and ensure that all parts of the sludge removal component can be effectively cleaned.

[0030] Specifically, while the dredging components are operating, the central control module 1 controls the first water pump 30 to start. The first water pump 30 draws clean water from the water tank 51 through a hose and the first outlet check valve 52, and pressurizes the clean water. The pressurized clean water is then transported to the distributor 36, and after being divided by the distributor 36, it is transported through multiple hoses to each inlet port 39, and then through the rotating connector 40 to each spray head 32. The spray head 32 atomizes the clean water and sprays it onto the dredging rollers 12, bearings 29, and other parts of the dredging components to spray and clean the sludge adhering to the surface, washing away the sludge and preventing it from adhering and clumping. The rotating connector 40 allows the spray head 32 to... 2. The rotating mechanism adjusts the spray angle to ensure that all parts of the dredging component are evenly sprayed, improving the cleaning effect. The water level detector 50 monitors the water level in the water tank 51 in real time. When the water level is lower than the preset threshold, it sends a signal to the central control module 1, which issues an early warning to remind the operator to add clean water to the water tank 51 through the inlet check valve 49. The inlet check valve 49 works in conjunction with the first outlet check valve 52 to ensure unidirectional delivery of clean water, prevent backflow, and ensure stable spray water supply. The two first cleaning components correspond to the two second rotating frames 31, which simultaneously spray and clean both sides of the dredging component, improving cleaning efficiency and cleaning effect.

[0031] In this embodiment, the second cleaning component located at the front includes a circular rack 35. Each spray head 32 has a first gear 33 fixedly sleeved on its outer periphery to drive the spray head 32 to rotate, and at the same time meshes with the circular rack 35 to transmit power. The circular rack 35 is rotatably mounted inside the interlayer of the second rotating frame 31 to drive multiple first gears 33 to rotate synchronously, thereby driving multiple spray heads 32 to rotate synchronously. Moreover, multiple first gears 33 mesh with the circular rack 35 to achieve synchronous power transmission. The second rotating frame 31 houses a second rotating motor 38, which serves as the power source for the second cleaning assembly and drives the circular rack 35 to rotate. Its output shaft is fixedly connected to the front of one of the bottom first gears 33 among a plurality of first gears 33, directly driving the first gear 33 to rotate, thereby driving the circular rack 35 to rotate. A first rubber seal 37 is fixedly connected to the rear side of the second rotating frame 31, which tightly abuts against the inner wall of the circular rack 35, providing a sealing and protective function to prevent sludge and sewage from entering the interlayer of the second rotating frame 31 and avoiding damage to components such as the circular rack 35 and the first gear 33. A plurality of cleaning scrapers 34 are fixedly connected to the rear side of the circular rack 35. The bristles of the cleaning scrapers 34 abut against the bearing 29 of the sludge removal roller 12, and are used to mechanically scrape and clean the sludge remaining on the surface of the bearing 29. This, in conjunction with the spray cleaning of the first cleaning assembly, achieves comprehensive cleaning of the bearing 29 and prevents sludge from caking and causing the sludge removal roller 12 to jam.

[0032] Specifically, while the first cleaning component performs spray cleaning, the central control module 1 controls the second rotating motor 38 to start. The output shaft of the second rotating motor 38 drives the bottom first gear 33, which is fixedly connected to it, to rotate. The first gear 33 meshes with the circular rack 35, causing the circular rack 35 to rotate inside the interlayer of the second rotating frame 31. When the circular rack 35 rotates, it drives multiple first gears 33 meshing with it to rotate synchronously. The multiple first gears 33 respectively drive the spray heads 32 fixedly sleeved on their respective peripheries to rotate. During the rotation, the spray heads 32 perform atomized spraying, expanding the spray range and improving the cleaning effect. At the same time, when the circular rack 35 rotates, it drives the rear... Multiple cleaning scrapers 34, fixedly connected to the side, rotate synchronously. The bristles of the cleaning scrapers 34 come into close contact with the bearings 29 of the sludge removal rollers 12, scraping away the residual sludge on the surface of the bearings 29 and cleaning away the sludge that was not rinsed off by the spray cleaning, thus achieving a comprehensive cleaning of the bearings 29. The first rubber seal 37 effectively prevents sludge and sewage from entering the interlayer of the second rotating frame 31, protecting components such as the circular rack 35 and the first gear 33 from being contaminated by sludge and causing jamming or damage. The two second cleaning components correspond to the two first cleaning components, and simultaneously clean the bearings 29 on both sides of the sludge removal components, ensuring that the sludge removal rollers 12 rotate smoothly and avoiding jamming problems.

[0033] In this embodiment, the fixing component includes a third support plate 43. Two sliding grooves 15 are symmetrically connected to both sides of the dredging equipment body 2 to provide sliding guidance for the limiting block 16 and the rack 53, ensuring smooth extension and retraction of the fixing pile 25. The third support plate 43 is fixedly assembled inside the dredging equipment body 2 to fix and install a dual-output shaft motor 41, providing stable support. The dual-output shaft motor 41 is installed on the top of the third support plate 43 as the power source of the fixing component, used to drive the two second rotating shafts 42 to rotate synchronously, thereby driving the fixing pile 25 to extend and retract. The two output shafts are fixedly connected to the second rotating shafts 42 to transmit power to the second gears 54. One end of each second rotating shaft 42 is fixedly connected to the second gear 54 to drive the rack 53 to slide. Each second gear 54 has a rack 53 meshing on one side, and the rack 53 is used to drive the limiting block 16 and the fixing pile 25 to slide up and down, realizing the extension and retraction of the fixing pile 25. Each rack 53 is fixedly connected to a limiting block 16 on one side to limit the sliding stroke of the rack 53 and prevent excessive sliding of the rack 53 from causing damage to the components. A fixing post 25 is fixedly connected to the bottom of the limiting block 16. The fixing post 25 has sharp teeth at the bottom for insertion into the underwater soil to achieve stable fixation of the equipment. Each sliding groove 15 is fixedly connected to a guide groove 55. The rack 53 slides in cooperation with the corresponding guide groove 55 to guide and limit, ensuring that the rack 53 slides smoothly and does not deviate. The two sliding grooves 15 slide in cooperation with the two limiting blocks 16 respectively to further improve the guiding and limiting effect and ensure that the fixing post 25 extends and retracts smoothly and is inserted vertically into the underwater soil.

[0034] Specifically, when the flow velocity sensing component detects a sudden change in water flow velocity and a collapse warning, the central control module 1 controls the dual-output shaft motor 41 to start. The two output shafts of the dual-output shaft motor 41 drive the two second rotating shafts 42 to rotate synchronously. The two second rotating shafts 42 respectively drive the second gear 54 fixedly connected to one end to rotate synchronously. The second gear 54 meshes with the rack 53, causing the rack 53 to slide downward along the guide groove 55. The rack 53 causes the limiting block 16 fixedly connected to one side to slide downward along the sliding groove 15. The limiting block 16 causes the fixed pile 25 fixedly connected to the bottom to move downward. The sharp teeth of the device are inserted into the underwater soil until the limit block 16 slides to the bottom limit position of the sliding groove 15. At this time, the dual output shaft motor 41 stops running, and the fixing pile 25 is firmly inserted into the underwater soil to stabilize and fix the body of the dredging equipment 2, preventing the equipment from shifting, tilting or being damaged under the impact of the collapse. When the risk of collapse is eliminated and the water flow rate returns to normal, the central control module 1 controls the dual output shaft motor 41 to reverse, which drives the second rotating shaft 42 and the second gear 54 to reverse, thereby driving the rack 53, the limit block 16 and the fixing pile 25 to slide upward. The fixing pile 25 is pulled out of the underwater soil and returns to the initial position. The placement does not affect the normal movement of the equipment and dredging operations; the guide groove 55 cooperates with the sliding groove 15 to ensure that the rack 53 and the limit block 16 slide smoothly and without deviation, ensuring the vertical extension and retraction of the fixed pile 25 and improving the fixing effect; at the same time, the first synchronous transmission mechanism drives the second rotating shaft 42 to rotate, assisting the dual output shaft motor 41 to drive the fixed component to operate, improving the response speed of the fixed component; the dual output shaft motor 41 adopts a high-power motor with sufficient power, which can quickly drive the extension and retraction of the fixed pile 25, improving the response speed of the collapse protection; the second gear 54 and rack 53 are both made of high-strength wear-resistant materials, meshing... The mating surfaces are treated with wear-resistant lubrication, ensuring smooth transmission without slippage and withstanding the impact force when the fixed pile 25 is inserted into the soil. The fixed pile 25 is made of high-strength alloy steel, and the sharp teeth at the bottom are hardened, resulting in high hardness and easy insertion into hard soil at the bottom of the water. The limiting block 16 is made of thickened steel plate with anti-rust and anti-corrosion treatment on the surface, providing effective limiting. The guide groove 55 is made of smooth and wear-resistant material, and the mating surface with the rack 53 is lubricated to ensure smooth sliding of the rack 53 without jamming. The sliding groove 15 is made of corrosion-resistant material with a smooth interior to reduce frictional loss when the limiting block 16 slides.

[0035] In this embodiment, the vibration assembly includes a sewage tank 14, multiple second return springs 62, and a hopper 8. The sewage tank 14 is fixedly installed inside the sludge removal equipment body 2 to collect the sewage separated during the sludge draining process for subsequent centralized discharge. A second water pump 59 is installed at the outlet of the sewage tank 14 to pump out and discharge the sewage collected in the sewage tank 14. A second one-way valve 58 is installed at the output port of the second water pump 59 to control the one-way output of sewage, prevent sewage from flowing back into the sewage tank 14, and ensure smooth sewage discharge. A first support plate 26 is fixedly connected to the top of the sewage tank 14 to install components such as the second cam 61 and the second return springs 62, providing stable support. The second cam 61 is rotatably installed inside the first support plate 26 to drive the hopper 8 to vibrate. The system achieves sludge draining. Multiple second return springs 62 are each surrounded by a second guide sleeve 60, which restricts the extension and retraction direction of the second return springs 62, preventing them from twisting and deforming under stress. The two ends of the second return springs 62 and the second guide sleeves 60 are fixedly connected to the bottom of the hopper 8 and the top of the first support plate 26, respectively, achieving elastic reset and stable vibration of the hopper 8. The hopper 8 receives the sludge transported by the adsorption assembly, achieving separation of sludge and wastewater during vibration. A second sludge pump 56 is installed on the left side of the hopper 8 to extract and discharge or transfer the drained sludge. A one-way sludge valve 57 is installed at its output port to control the one-way output of the drained sludge, preventing sludge from flowing back into the hopper 8 and ensuring smooth sludge discharge.

[0036] Specifically, after the adsorption component conveys the sludge into the hopper 8, the second synchronous transmission mechanism drives the second cam 61 to rotate. During the high-speed rotation of the second cam 61, it continuously abuts against the bottom of the hopper 8, pushing the hopper 8 to reciprocate up and down along the direction of the second guide sleeve 60. When the hopper 8 reciprocates, multiple second return springs 62 perform reciprocating motions of stretching and compression, providing elastic return power to the hopper 8 and ensuring that the hopper 8 can reciprocate stably and continuously. Under the action of vibration, the sludge in the hopper 8 contains wastewater that is separated out. The wastewater falls through the screen holes at the bottom of the hopper 8 into the wastewater pool 14 below, achieving the draining treatment of the sludge. The volume of sludge is significantly reduced, saving equipment storage space; after the sewage in the sewage tank 14 accumulates to a certain amount, the central control module 1 controls the second water pump 59 to start, and the sewage is discharged through the second outlet check valve 58; after the sludge in the hopper 8 is drained, the central control module 1 controls the second sludge pump 56 to start, and the drained sludge is discharged or transferred through the sludge outlet check valve 57, completing the sludge draining and discharge; the second guide sleeve 60 ensures that the vibration of the hopper 8 is stable and does not deviate, improving the sludge draining effect; the second synchronous transmission mechanism drives the second cam 61 to operate synchronously with the sludge cleaning component, realizing the coordinated linkage of sludge cleaning and sludge draining, and improving the overall operation efficiency.

[0037] In this embodiment, the first synchronous transmission mechanism includes a second synchronous toothed belt 17, and a third synchronous toothed pulley 22 is fixedly connected to the rear end of the first rotating shaft 21 for transmitting power to the first rotating shaft 21. The third synchronous toothed pulley 22 is connected to the fourth synchronous toothed pulley 23 through the second synchronous toothed belt 17 to realize synchronous power transmission. The fourth synchronous toothed pulley 23 is fixedly connected to the second rotating shaft 42, and the second rotating shaft 42 passes through the center point of the fourth synchronous toothed pulley 23 to ensure that the fourth synchronous toothed pulley 23 rotates synchronously with the second rotating shaft 42, transmitting power to the second rotating shaft 42, thereby driving the fixed component to run, and realizing synchronous linkage between the flow rate sensing component and the fixed component.

[0038] Specifically, when the flow velocity sensing component is running, the first rotating shaft 21 rotates, driving the third synchronous toothed pulley 22, which is fixedly connected to the rear end, to rotate synchronously. The third synchronous toothed pulley 22 transmits power to the fourth synchronous toothed pulley 23 through the second synchronous toothed belt 17. Since the third synchronous toothed pulley 22 and the fourth synchronous toothed pulley 23 are driven by the synchronous toothed belt, their speeds are consistent. The fourth synchronous toothed pulley 23 drives the second rotating shaft 42, which is fixedly connected to it, to rotate synchronously. The second rotating shaft 42 drives the second gear 54 to rotate, which in turn drives the rack 53, limit block 16, and fixing stake 25 of the fixing component to slide, thereby realizing the operation of the fixing component. When the flow velocity detection module 20 detects a sudden change in water flow velocity, the central control module 1 controls the first rotating shaft 21 to speed up, which quickly drives the second rotating shaft 42 to rotate through the first synchronous transmission mechanism, linking the fixing component to start quickly, realizing the rapid fixing of the equipment and improving the response speed of the collapse protection. At the same time, the linkage design of the first synchronous transmission mechanism eliminates the need to equip the fixing component with a separate power source auxiliary dual-output shaft motor 41, simplifying the equipment structure and reducing energy consumption.

[0039] In this embodiment, the second synchronous transmission mechanism includes a first synchronous toothed belt, and a second synchronous toothed pulley 18 is fixedly connected to the front end of the dredging roller 12 for transmitting power to the dredging roller 12; the second synchronous toothed pulley 18 is connected to the first synchronous toothed pulley 13 through the first synchronous toothed belt to realize synchronous power transmission; the first synchronous toothed pulley 13 is fixedly connected to the front end of the second cam 61 to drive the second cam 61 to rotate synchronously, thereby driving the vibration component to operate, realizing synchronous operation of the dredging component and the vibration component, and improving work efficiency.

[0040] Specifically, when the dredging assembly is running, the first rotating motor 24 drives the dredging roller 12 to rotate, and the second synchronous toothed pulley 18, which is fixedly connected to the front end of the dredging roller 12, rotates synchronously. The second synchronous toothed pulley 18 transmits power to the first synchronous toothed pulley 13 through the first synchronous toothed belt. Since the second synchronous toothed pulley 18 and the first synchronous toothed pulley 13 are driven by the synchronous toothed belt, their speeds are consistent. The first synchronous toothed pulley 13 drives the second cam 61, which is fixedly connected to it, to rotate synchronously. The second cam 61 drives the hopper 8 to vibrate back and forth, realizing the operation of the vibration assembly. Through the linkage of the second synchronous transmission mechanism, the dredging assembly and the vibration assembly operate synchronously. The sludge generated by dredging is promptly transported into the hopper 8 for draining treatment, avoiding sludge accumulation and improving overall operation efficiency. At the same time, there is no need to equip the vibration assembly with a separate power source, simplifying the equipment structure, reducing energy consumption, and achieving efficient power transmission.

[0041] The implementation principle of a sluice gate dredging device according to an embodiment of this application is as follows: 1. Equipment Start-up and Flow Rate Detection: The central control module 1 starts all components, the crawling component 7 drives the equipment to move slowly, the camera module 3 captures the operation scene in real time and feeds it back to the operator; the flow rate sensing component starts synchronously, the flow rate detection module 20 continuously detects the water flow rate in the sluice gate and feeds back the detection data to the central control module 1 in real time; at the same time, the first synchronous transmission mechanism drives the first rotating shaft 21 to rotate, the first rotating shaft 21 drives the first cam 46 to rotate, driving the protective cover 44 to vibrate back and forth, shaking off the surface sludge, ensuring accurate flow rate detection; the second rubber seal 47 seals and protects the flow rate detection module 20 to prevent sludge from entering.

[0042] 2. Dredging and Adsorption Linkage: The central control module 1 controls the first rotating motor 24 to start, driving the dredging roller 12 to rotate at high speed. The scraping teeth on the surface of the dredging roller 12 scrape and break the sludge at the bottom of the sluice gate, and the sludge is guided into the guide channel 4. At the same time, the first sludge pump 10 starts, and adsorbs the sludge in the guide channel 4 through the conduit 11 and the sludge inlet one-way valve 28, and transports the sludge into the hopper 8, realizing the synchronous linkage of dredging and adsorption, and avoiding sludge accumulation. The mud baffle 6 prevents sludge splashing and protects the rear components of the equipment and the camera module 3.

[0043] 3. Innovative Features of Self-Cleaning Bearing Anti-Clogging in Dredging Components: During dredging operations, the first and second cleaning components start simultaneously. The first water pump 30 starts, pressurizing the clean water in the water tank 51 and then delivering it to the spray head 32 via the distributor 36, water inlet 39, and rotating connector 40. The spray head 32 rotates and atomizes the water, cleaning the dredging roller 12 and bearing 29. Simultaneously, the second rotating motor 38 starts, driving the bottom first gear 33 to rotate, which in turn drives the circular rack 35 and multiple first gears 33 to rotate synchronously. The spray head 32 rotates to expand the spray range, and the cleaning scraper 34 rotates synchronously to scrape away residual sludge on the surface of the bearing 29. Combined with the spray cleaning, this achieves comprehensive cleaning of the bearing 29 and prevents sludge from caking and causing the dredging roller 12 to jam. The first rubber seal 37 prevents sludge from entering the interlayer of the second rotating frame 31, protecting the transmission components. The water level detector 50 monitors the water level in the water tank 51 in real time and reminds the user to replenish the water when it is low.

[0044] 4. Space-Saving Innovation in Sludge Drainage: During sludge removal and cleaning operations, the second synchronous transmission mechanism drives the sludge removal roller 12 and the vibration component to operate synchronously. The sludge removal roller 12 drives the second synchronous toothed pulley 18 to rotate, and transmits power to the first synchronous toothed pulley 13 through the first synchronous toothed belt, which drives the second cam 61 to rotate. The second cam 61 drives the hopper 8 to vibrate back and forth along the second guide sleeve 60, and the second return spring 62 cooperates to achieve stable vibration. Under the action of vibration, the sludge in the hopper 8 is separated from the sewage and falls into the sewage tank 14 through the screen holes. After the sewage accumulates to a certain amount, the second water pump 59 starts and pumps the sewage out through the second outlet check valve 58. The volume of the drained sludge is greatly reduced, saving equipment storage space and improving the continuity of sludge removal. After the sludge is drained, the second sludge pump 56 starts and pumps the drained sludge out through the sludge outlet check valve 57 for discharge or transfer.

[0045] 5. Collapse Early Warning and Fixation Innovation: When the flow velocity detection module 20 detects a sudden change in water flow velocity exceeding a preset threshold, the central control module 1 determines it as a silt collapse early warning, immediately issues a signal, and simultaneously controls the equipment to decelerate and stop moving, suspending the operation of the sludge removal, adsorption, and cleaning components; the first synchronous transmission mechanism increases power output, and the third synchronous toothed pulley 22 drives the fourth synchronous toothed pulley 23 and the second rotating shaft 42 to rotate rapidly through the second synchronous toothed belt 17, cooperating with the dual output shaft motor 41 to drive the second gear 54 to rotate, causing the rack 53, limit block 16, and fixing pile 25 to slide rapidly downwards; the sharp teeth at the bottom of the fixing pile 25 insert into the bottom soil until the limit block 16 reaches the limit position, achieving stable fixation of the equipment and preventing the equipment from shifting or being damaged due to the impact of the collapse; the guide groove 55 and the sliding groove 15 ensure the vertical extension and retraction of the fixing pile 25, improving the fixing effect.

[0046] 6. Collapse Relief and Equipment Reset: When the flow velocity detection module 20 detects that the water flow velocity has returned to normal and the collapse risk has been eliminated, the central control module 1 controls the dual output shaft motor 41 to reverse. Through the linkage of the first synchronous transmission mechanism, the second rotating shaft 42 and the second gear 54 are driven to reverse, driving the rack 53, limit block 16, and fixed pile 25 to slide upward and reset to the initial position. After checking whether the various components of the equipment are damaged and confirming that there are no abnormalities, the dredging, adsorption, and cleaning components are restarted to continue the dredging operation.

[0047] Example 2 The difference between this embodiment and embodiment one is that multiple heat-conducting plates are installed inside the first rotating frame 5. These multiple heat-conducting plates can heat the dredging roller 12, thereby enhancing the dredging roller 12's efficiency in cleaning frozen sludge.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
