[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Reference Figure 1 , Figure 2This utility model provides an embodiment of a high-efficiency dredging device for water conservancy and hydropower construction, comprising a support platform 1, which serves as the installation foundation for the entire device, supporting various functional components and ensuring structural stability. A dredging component 2 is fixedly connected to the bottom front of the support platform 1, used to crush and initially collect silt from the bottom of a water channel 6. A walking component 3 is fixedly connected to the outside of the support platform 1, enabling the entire device to move along the water channel 6 for continuous dredging operations. A conveying component 4 is fixedly connected inside the support platform 1, used to transport the silt collected by the dredging component 2 to a silt discharge component 5. A silt discharge component 5 is fixedly connected to the top rear of the support platform 1, responsible for collecting and discharging the silt. A water channel 6 is slidably connected to the bottom of the walking component 3, providing a track for the device and defining its operating range. 2 includes two lifting hydraulic cylinders 21. The lifting hydraulic cylinders 21 can realize the extension and retraction of the piston rod 22 through hydraulic drive, thereby adjusting the height of the dredging frame 23 to adapt to silt layers of different depths. The piston rod 22 is fixedly connected to the drive end of the lifting hydraulic cylinder 21. The piston rod 22 can convert the hydraulic energy of the lifting hydraulic cylinder 21 into mechanical energy, driving the dredging frame 23 to move up and down. The dredging frame 23 is fixedly connected to the bottom of the two piston rods 22. The dredging frame 23 provides installation support for other parts of the dredging component 2, and at the same time protects the internal parts from the impact of silt. The motor a24 is fixedly connected inside the dredging frame 23. The motor a24 provides power for the rotation of the forward rotating shaft 25 and is the power source for dredging and crushing. The forward rotating shaft 25 is fixedly connected to the drive end of the motor a24. The forward rotating shaft 25 rotates under the drive of the motor a24, driving the forward crushing blade 27 and the drive gear 26 to rotate synchronously. A drive gear 26 is fixedly connected to the outside of the forward rotating shaft 25. The drive gear 26, through meshing with the driven gear 28, transmits the power of the forward rotating shaft 25 to the reverse rotating shaft 29, achieving reverse rotation. The external part of the forward rotating shaft 25 is rotatably connected to the inside of the dredging frame 23, which provides rotational support for the forward rotating shaft 25, ensuring its rotational stability. Multiple forward crushing blades 27 are fixedly connected to the outside of the forward rotating shaft 25. The forward crushing blades 27 rotate with the forward rotating shaft 25, performing forward cutting and crushing of the silt, capable of breaking up larger silt clumps. The reverse rotating shaft 29 is rotatably connected inside the dredging frame 23, and the reverse rotating shaft 29, driven by the driven gear 28, reverses... The forward rotation provides rotational power to the reverse crushing blades 210. A driven gear 28 is fixedly connected to the external side of the reverse rotation shaft 29. The driven gear 28 meshes with the driving gear 26, converting the rotational motion of the driving gear 26 into reverse rotation and transmitting it to the reverse rotation shaft 29. The driving gear 26 and the driven gear 28 mesh with each other, and their meshing transmission ensures the synchronous reverse rotation of the forward rotation shaft 25 and the reverse rotation shaft 29, forming a shearing force to enhance the crushing effect. Multiple reverse crushing blades 210 are fixedly connected to the external side of the reverse rotation shaft 29. The reverse crushing blades 210 rotate in the opposite direction with the reverse rotation shaft 29, and cooperate with the forward crushing blades 27 to form a shearing force, which crushes silt and impurities more efficiently.
[0013] Reference Figure 1 , Figure 3The walking assembly 3 includes multiple drive shafts 31, which transmit power to the walking wheels 32, causing them to rotate. The drive shafts 31 are externally fixedly connected to the interior of the support platform 1, which provides mounting points for the drive shafts 31 to ensure their stability during operation. The walking wheels 32 are externally fixedly connected to the drive shafts 31, and these wheels contact the top of the water channel 6, rotating to move the entire device. The walking wheels 32 are externally slidably connected to the top of the water channel 6, with the top of the water channel 6 serving as the top surface for the walking wheels 32. The system provides support and a moving track to ensure the device moves along a preset path. The conveying assembly 4 includes a U-shaped conveying cylinder 41, which provides a channel for sludge conveying and prevents sludge spillage during transport. The U-shaped conveying cylinder 41 is externally fixed to the inside of the carrying platform 1. The carrying platform 1 fixes the U-shaped conveying cylinder 41 to ensure it does not shake during sludge conveying. A support block 42 is fixedly connected to the top of the carrying platform 1. The support block 42 supports and fixes the motor b43, ensuring the stability of the motor b43 during operation. The top of the support block 42... A motor b43 is fixedly connected to the screw conveyor shaft 44, providing power for its rotation. The screw conveyor shaft 44 is fixedly connected to the drive end of the motor b43. Driven by the motor b43, the screw conveyor shaft 44 rotates, causing the screw blades 49 to rotate. The screw blades 49 are fixedly connected to the outside of the screw conveyor shaft 44. The screw blades 49 rotate with the screw conveyor shaft 44, pushing the sludge within the U-shaped conveyor cylinder 41 to achieve horizontal sludge transport. A motor c45 is fixedly connected to the outside of the U-shaped conveyor cylinder 41. The drive column c46 is fixedly connected to the drive end of the motor c45 to provide power for the rotation of the drive column c46. The drive column c46 rotates under the drive of the motor c45, which drives the conveyor belt 47 to run. The external coupling of the drive column c46 is connected to the conveyor belt 47. The conveyor belt 47 circulates under the drive of the drive column c46, which drives the scraper 48 to move. Multiple scrapers 48 are fixedly connected to the external of the conveyor belt 47. The scrapers 48 move with the conveyor belt 47 and can scrape off the sludge adhering to the inner wall of the U-shaped conveyor cylinder 41 to prevent sludge residue from clogging. The sludge removal assembly 5 includes a collection box 51, which is used to temporarily store the sludge transported by the conveying assembly 4 for convenient centralized processing. The bottom of the collection box 51 is fixedly connected to the top of the support platform 1. The support platform 1 fixes the collection box 51 to ensure that it will not tip over during the movement of the device. A water pump 52 is fixedly connected to the top of the support platform 1. The water pump 52 generates negative pressure to extract the sludge from the collection box 51. The support platform 1 provides installation support for the water pump 52. A sludge suction pipe 53 is fixedly connected inside the water pump 52. The sludge suction pipe 53 introduces the sludge from the collection box 51 into the water pump 52. The other end of the sludge suction pipe 53 is fixedly connected to the inside of the collection box 51. The sludge in the collection box 51 enters the water pump 52 through the sludge suction pipe 53. A sludge discharge pipe 54 is fixedly connected inside the water pump 52. The sludge discharge pipe 54 transports the sludge pumped out by the water pump 52 to a designated location to complete the sludge removal operation.
[0014] Working principle: After the device is started, the drive shaft 31 in the walking component 3 starts to rotate, driving the external walking wheel 32 to slide on the top of the water channel 6, thereby moving the entire carrying platform 1 to the designated position where sludge needs to be dredged. After reaching the sludge dredging position, the sludge dredging component 2 starts to work. The lifting hydraulic cylinder 21 drives the piston rod 22 to extend and retract, thereby driving the sludge dredging frame 23 to descend to a suitable depth to contact the sludge in the water channel 6. Subsequently, the motor a24 starts, and its drive end drives the forward rotating shaft 25 to rotate. The drive gear 26 fixed outside the forward rotating shaft 25 rotates together. Since the drive gear 26 meshes with the driven gear 28 outside the reverse rotating shaft 29, the rotation of the forward rotating shaft 25 will drive the reverse rotating shaft 29 to rotate in the opposite direction. During this process, multiple forward crushing blades 27 outside the forward rotating shaft 25 and multiple reverse crushing blades 210 outside the reverse rotating shaft 29 rotate synchronously in opposite directions to fully crush the sludge in the water channel 6 for subsequent transportation. The crushed sludge enters the U-shaped conveyor cylinder 41 of the conveying assembly 4. At this time, the motor b43 on the top of the support block 42 starts, and its drive end drives the spiral conveyor shaft 44 to rotate. The spiral blades 49 on the outside of the spiral conveyor shaft 44 rotate accordingly, conveying the sludge in the U-shaped conveyor cylinder 41 horizontally. At the same time, the motor c45 on the outside of the U-shaped conveyor cylinder 41 starts, driving the drive column c46 to rotate. The drive column c46 drives the conveyor belt 47 to rotate through the coupling connection. Multiple scrapers 48 on the outside of the conveyor belt 47 move together with the conveyor belt 47, further scraping and conveying the sludge, so that the sludge can smoothly enter the collection box 51 of the sludge discharge assembly 5. When a certain amount of sludge is collected in the collection box 51, the water pump 52 on the top of the bearing platform 1 starts, and the sludge in the collection box 51 is extracted through the sludge extraction pipe 53, and then discharged to the designated location through the sludge discharge pipe 54, completing the entire sludge removal operation process.
