Description

Technical Field

[0001] This utility model relates to the field of river sediment cleaning technology, and in particular to a device for cleaning river sediments. Background Technology

[0002] River sediments are solid particulate matter carried and deposited by river currents on riverbeds, banks, and surrounding areas during river flow. These sediments typically consist of multiple components, primarily fine soil particles (such as clay, silt, and sand), which are the main components of river sediments. Silt and sand particles are generally small in size and easily carried by water currents, including plant remains, animal carcasses, and other organic matter. These organic materials decompose within the sediments, providing nutrients to the water body. The geological environment through which the river flows influences the composition of the sediments, including quartz, feldspar, and clay minerals. Due to human activities (such as agricultural, industrial, and urban emissions), river sediments may contain heavy metals, chemicals, and other pollutants. Therefore, dredging equipment is often required for sediment cleanup.

[0003] A search revealed Chinese Patent Publication No. CN206693189U, which discloses a river cleaning device for water conservancy and hydropower. The device includes a main support plate, a first support rod, a second support rod, conical counterweights, and an airbag. A mudguard is installed near the bottom of the first support rod, and five conical counterweights are evenly fixed to the other end of the mudguard. A first screen is installed in the space formed between the mudguard and the first support rod. A second fixing rod is fixed to the top of the second support rod, and a second screen is installed between the second support rod and the second fixing rod. The airbag is positioned between the auxiliary support plates. By installing the mudguard and conical counterweights at the bottom of the first support plate, it is convenient to collect and clean sediment from the bottom of the river. With the assistance of the first screen, dredging can also be performed. By fixing the second support rod to the upper part of the main support plate and installing the second screen, floating debris on the river surface can also be collected and cleaned during river cleaning, making it convenient and practical.

[0004] The specific implementation of the above-mentioned patent description mentions that "the first support rod 3 is set as a telescopic rod, and a positioning locking part is provided at its telescopic position to facilitate adjustment of the depth of the entire device in the water, and to facilitate cleaning of rivers of different depths. The aperture of the first screen 7 is set to 1-2 mesh, and the aperture of the second screen 10 is set to 5-10 mesh, which can screen and retrieve different types of garbage. The vertical height of the airbag protection plate 14 is not lower than the vertical height of the airbag 12 when it is inflated, which can better protect the airbag 12 and reduce water resistance during the journey. The auxiliary support plate 2 is provided with hanging rings 11 on both outer sides to facilitate mounting the device on a power boat for cleaning work." However, in the process of cleaning impurities and sediments, it is not possible to effectively and actively clean the sediments at the bottom of the river, nor is it convenient to adjust the position of digging and cleaning.

[0041] 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.

[0042] Reference Figure 1 , Figure 4 , Figure 5 An embodiment of this utility model provides: a device for cleaning river sediments, including a digging cantilever connecting frame 8, a connecting plate 10, and a digging bucket 24. A driving component is fixedly connected to the top of the digging cantilever connecting frame 8, a moving component is fixedly connected to the outside of the driving component, and a support component is slidably connected to the outside of the moving component. A fixed seat 11 is fixedly connected to the outer side of the connecting plate 10. A large arm 12 is rotatably connected to the outer side of the fixed seat 11, i.e., the side away from the connecting plate 10. A small arm 17 is rotatably connected to the bottom of the large arm 12. A connecting seat 20 is rotatably connected to the bottom of the small arm 17. A rotating mechanism is fixedly connected between the bottom of the digging cantilever connecting frame 8 and the top of the connecting plate 10, and between the outer side of the connecting seat 20 and the outer side of the digging bucket 24.

[0043] The rotating mechanism includes a housing 27, a central shaft 28 is rotatably connected inside the housing 27, a worm gear 29 is fixedly connected to the outside of the central shaft 28, side protective shells 30 are fixedly connected to both sides of the outer side of the housing 27, a motor 31 is fixedly connected to one side of the outer side protective shell 30, a worm gear 32 is fixedly connected to the drive end of the motor 31, a rotating wheel 33 is fixedly connected to the bottom of the central shaft 28, a follower sleeve 34 is slidably connected to the outside of the rotating wheel 33, mounting holes 35 are evenly opened around the rotating wheel 33 and the follower sleeve 34, and a lead screw 36 is threadedly connected to the inner wall of the multiple mounting holes 35 opened on the same side of the rotating wheel 33 and the follower sleeve 34.

[0044] Specifically, the excavating cantilever connecting frame 8 is the supporting structure of the entire device, responsible for connecting and supporting the excavating bucket 24 and other components. It is made of high-strength materials to ensure it can withstand large loads during excavation. The connecting plate 10 acts as a bridge connecting different components, ensuring coordinated operation between them. The design of the connecting plate 10 needs to consider strength and rigidity to withstand various forces generated during excavation. The outer shell 27 serves as the main protective structure for the rotating mechanism, protecting the internal components and providing a mounting base for other parts. The outer shell 27 is made of high-strength materials (such as steel or aluminum alloy) to withstand mechanical stress during operation. Considering factors such as heat dissipation, sealing, and dust prevention to ensure the normal operation of internal components, the central shaft 28 is the core component of the rotating mechanism, responsible for transmitting the power generated by the motor 31, causing the worm gear 29 and other components to rotate. The central shaft 28 is made of high-strength alloy material, which has good bending and torsional resistance. Its surface is specially treated to reduce friction and wear. The worm gear 29 works in conjunction with the worm 32 to convert the rotational motion of the motor 31 into the rotation of the central shaft 28. It is usually used to reduce the speed and increase the torque. The tooth profile of the worm gear 29 is precisely designed to ensure smooth meshing with the worm 32. The material is a wear-resistant alloy to extend its service life.

[0045] Reference Figures 1 to 3 The support assembly includes four vertical steel beams 1. Two vertical steel beams 1 on the same side are fixedly connected to a steel crossbeam 2 on adjacent sides. The moving assembly is slidably connected to the top of the two steel crossbeams 2, i.e., on adjacent sides of the two steel crossbeams 2. The moving assembly includes a sliding platform 3. Two moving reinforcement frames 4 are fixedly connected to the inner wall of the sliding platform 3. Auxiliary wheels 5 are fixedly connected to the bottom of the moving reinforcement frames 4. The bottom of the auxiliary wheels 5 is slidably connected to the top of the sliding platform 3. A fixed plate 6 is fixedly connected to adjacent sides of the two moving reinforcement frames 4. The top of the drive assembly is fixedly connected to the bottom of the fixed plate 6. The top of the drive assembly includes a hydraulic cylinder 9, which is fixedly connected to the bottom of the fixed plate 6. The drive end of the hydraulic cylinder 9 is fixedly connected to the top of the excavating cantilever connecting frame 8. Lifting auxiliary rods 7 are fixedly connected to the four corners inside the fixed plate 6. The inner side of the excavating cantilever connecting frame 8 is slidably connected to the outside of multiple lifting auxiliary rods 7.

[0046] Specifically, the drive assembly enables the digging bucket 24 to be raised, lowered, and moved laterally through its movement. The drive assembly provides power, allowing the digging cantilever connecting frame 8 to rise, lower, and move. This includes a hydraulic cylinder 9 or a motor 31 drive system that converts power into mechanical motion. The stability and power of the drive assembly directly affect the overall working efficiency of the device. The support assembly provides structural support, ensuring the stability of the entire device during operation. It consists of four vertical steel beams 1 and a steel crossbeam 2, forming a robust frame structure. The design of the support assembly takes load distribution into account, ensuring that tilting or instability does not occur during digging.

[0047] Reference Figure 4 The bottom of the fixed base 11 is fixedly connected to two support plates 15. The inner wall of the corner of the boom 12 is fixedly connected to two support plates 14. A hydraulic rod 16 is rotatably connected between the two support plates 14 and the two support plates 15. The top of the forearm 17 is fixedly connected to two support plates 18. The top corner of the boom 12 is fixedly connected to two support plates 13. A hydraulic rod 19 is rotatably connected between the two support plates 18 and the two support plates 13. The inside of the connecting base 20 is rotatably connected to the connecting shaft 21. Both sides of the connecting shaft 21 are rotatably connected to arc-shaped connecting plates 22. The other side of the arc-shaped connecting plates 22 is rotatably connected to the bottom side of the forearm 17. A hydraulic rod 23 is fixedly connected between the two support plates 18 and the connecting shaft 21. Multiple drainage holes 25 are opened on both sides and the bottom of the excavating bucket 24. Multiple breaking claws 26 are fixedly connected to the front side of the excavating bucket 24.

[0048] Specifically, the fixed base 11 provides support and connection points for the boom 12, ensuring its flexible movement. Made of robust material, it has a support plate 15 fixedly connected to its bottom, effectively distributing the load. The boom 12 and forearm 17 together form the operating arm of the digging bucket 24. A rotating connection enables the digging bucket 24 to move flexibly. A support plate 14 is fixedly connected to the inner wall of the corner of the boom 12, and a support plate 18 is fixedly connected to the top of the forearm 17, ensuring no loosening or deformation during movement. The connecting base 20 connects the forearm 17 to the digging bucket 24, transmitting motion and force. An internal connecting shaft 21 is rotatably connected, and arc-shaped connecting plates 22 are rotatably connected to both sides of the connecting shaft 21, ensuring... The flexible connection between the forearm 17 and the digging bucket 24 is ensured. The rotating mechanism enables the digging bucket 24 to rotate and tilt, enhancing the flexibility and efficiency of digging. It includes components such as the outer shell 27, central shaft 28, worm gear 29, and worm 32. The motor 31 drives the worm 32, which in turn drives the worm gear 29 and central shaft 28 to rotate, thereby realizing the rotation of the digging bucket 24. The digging bucket 24 is directly used to clean sediment in the river channel and has the functions of digging and transporting. Multiple drainage holes 25 are opened at the bottom and sides to facilitate drainage during the digging process and prevent the sediment from affecting the weight and operation due to excessive water. Multiple crushing claws 26 are fixedly connected to the front of the exterior for crushing relatively hard sediment.

[0049] Working principle: First, the drive assembly generates power through motor 31 or hydraulic cylinder 9, driving the excavator cantilever connecting frame 8 to rise, fall, and move laterally. The sliding platform 3 in the moving assembly slides along the steel beam 2 with the support of the support assembly, thus achieving horizontal movement of the entire device. The drive assembly is fixedly connected to the top of the excavator cantilever connecting frame 8 to ensure stable movement.

[0050] During excavation, the fixed base 11 enables the flexible movement of the excavating bucket 24 via the rotatably connected boom 12 and arm 17. The boom 12 is connected to the hydraulic rod 16 between the support plate 2 14 and the support plate 3 15, allowing for adjustment as needed. The top of the arm 17 is fixedly connected to the support plate 4 18, which is rotatably connected to the support plate 13 via the hydraulic rod 2 19, further enhancing the operational flexibility of the excavating bucket 24.

[0051] As the device approaches the sediment to be cleared, the digging bucket 24 begins to sink. Multiple drainage holes 25 on the bottom and sides allow excess water to drain out, ensuring that the digging bucket 24 is not burdened by excessive water when handling sediment. The breaker claws 26 on the outer front side of the digging bucket 24 effectively break up harder sediment, making it easier to dig and transport.

[0052] The worm gear 32 and worm wheel 29 in the rotating mechanism enable the central shaft 28 to rotate, thereby driving the digging bucket 24 to tilt and rotate as necessary, further improving the flexibility and efficiency of digging. Through these coordinated movements, the device can efficiently complete the cleaning of river sediments, ensuring the unobstructed flow of the river and the cleanliness of the environment.

[0053] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
