Description

Technical Field

[0001] This utility model relates to the field of dredging device technology, and in particular to an anti-clogging dredging device for water conservancy projects. Background Technology

[0002] In the maintenance of water conservancy projects, the accumulation of silt in channels and small waterways can easily cause water flow blockage, affecting irrigation and drainage functions. Existing dredging methods are difficult to balance the needs of dredging effectiveness with environmental protection and operational safety. If heavy equipment such as excavators is used for dredging, the weight of the equipment itself and the mechanical force during operation can easily crush the riverbank soil, leading to riverbank collapse and structural damage. At the same time, the movement of heavy equipment can also damage surrounding supporting roads, increasing the cost of later repairs. If dredging vessels are used, although they are suitable for aquatic environments, in areas with shallow water, narrow channels, or rapid currents, the vessels are prone to running aground or capsizing, posing significant safety hazards, and it is difficult to accurately control the operating area.

[0003] More importantly, existing dredging equipment generally lacks flexible adjustment capabilities. The dredging depth is mostly fixed and cannot be dynamically adjusted according to the thickness of the silt layer. This easily leads to problems such as incomplete dredging or over-excavation that damages the riverbed. The dredging distance is also limited by the equipment's operating radius, making it difficult to clean silt in the center of the river or in areas far from the embankment. Frequent equipment movement is required, which further increases the risk of damage to river embankments and roads. At the same time, it reduces dredging efficiency and fails to meet the actual needs of water conservancy projects for low-damage, high-safety, and adjustable dredging operations.

[0004] Therefore, it is necessary to invent an anti-clogging and dredging device for water conservancy projects to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that existing dredging equipment generally lacks flexible adjustment capabilities and requires frequent relocation during use, which further exacerbates the risk of damage to river embankments and roads. Therefore, this utility model provides an anti-clogging dredging device for water conservancy projects.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a dredging and anti-clogging device for water conservancy projects, comprising a movable component, the movable component comprising a movable base, a sludge storage box with a sludge inlet on its surface placed on the movable base, an installation platform fixedly mounted on the movable base, a fixed pipe assembly rotatably mounted on the sludge storage box, a movable rod assembly slidably mounted on the fixed pipe assembly, the fixed pipe assembly and the movable rod assembly being extended, retracted and steered by adjusting the assembly, and a dredging component for extracting sludge mounted on the movable base.

A toothed plate is fixedly connected to the movable rod, and a sliding groove is opened on its surface. The size of the groove matches the L-shaped movable rod and the toothed plate. A cylinder is fixedly connected to one end of the L-shaped movable rod through a mounting plate, and a connecting plate is fixedly connected to the output end of the cylinder.

[0009] As a further description of the above technical solution: the adjustment component includes a first motor fixedly connected to the top of the sludge storage tank, and a gear ring fixedly sleeved on the outside of the column, wherein the output end of the first motor is fixedly connected to a first gear meshing with the gear ring.

[0010] As a further description of the above technical solution: the adjustment component also includes a rotating cover plate fixedly connected to the bottom of the column and in contact with the top of the sludge storage tank. A support plate is fixedly connected to the rotating cover plate, and a second motor is fixedly installed on the support plate. The output end of the second motor is fixedly connected to a second gear that meshes with the gear plate.

[0011] As a further description of the above technical solution: the dredging component includes a suction pump fixedly connected to the mounting platform.

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] Please refer to the figure. The present invention provides a technical solution: a dredging and anti-clogging device for water conservancy projects, including a movable component 1. The movable component 1 includes a movable base 13, on which a sludge storage box 11 with a sludge inlet 12 is placed. An installation platform 14 is also fixedly installed on the movable base 13. The movable component 1 also includes a self-locking universal wheel 15 fixedly connected to the bottom of the movable base 13, and a push handle 16 fixedly connected to one end of the movable base 13. A fixed pipe assembly 2 is rotatably installed on the sludge storage box 11, and a movable rod assembly 4 is slidably installed on the fixed pipe assembly 2. The fixed pipe assembly 2 and the movable rod assembly 4 can extend, retract, and turn by adjusting the assembly. A dredging component 5 for extracting sludge is also provided on the movable base 13.

[0019] Therefore, in actual use, the staff pushes the push handle 16 of the mobile component 1 and moves the device to the dredging operation point of the river or canal through the universal wheels at the bottom of the mobile seat 13. After adjusting the position of the mobile seat 13 according to the silt distribution area, the self-locking universal wheel 15 is locked to ensure the stability of the device. At this time, the silt storage box 11 and the mounting platform 14 are fixed with the mobile seat 13, the silt suction pump 51 of the dredging component 5 is in standby mode, and the silt inlet pipe 53 is initially in a non-operational position to avoid collision with the river embankment or obstacles.

[0020] like Figures 2-5As shown, in order to adjust the dredging angle, range, and depth, this utility model is provided with a fixed pipe assembly 2, a moving rod assembly 4, and an adjusting assembly 3. The fixed pipe assembly 2 includes a column 21 rotatably mounted above the sludge storage tank 11 via a bearing seat. A fixed block 22 is fixedly connected to the top of the column 21. A fixed sleeve 23 is fixedly connected to one side of the fixed block 22. A through slot 24 is opened on the fixed sleeve 23 and the fixed block 22. A limit block 25 is also fixedly connected to one end of the fixed sleeve 23. The moving rod assembly 4 includes an L-shaped moving rod 41 that is slidably sleeved inside the fixed sleeve 23. A toothed plate 42 is fixedly connected to the moving rod, and a sliding groove 43 is opened on its surface. The size of the groove 24 matches the L-shaped moving rod 41 and the toothed plate 42. A cylinder 45 is fixedly connected to one end of the L-shaped moving rod 41 via a mounting plate 44. A connecting plate 46 is fixedly connected to the output end of the cylinder 45.

[0021] Specifically, such as Figures 2-4 As shown, the adjustment assembly 3 includes a first motor 31 fixedly connected to the top of the sludge storage tank 11, and a gear ring 33 fixedly sleeved on the outside of the column 21. The output end of the first motor 31 is fixedly connected to a first gear 32 that meshes with the gear ring 33. The adjustment assembly 3 also includes a rotating cover plate 34 fixedly connected to the bottom of the column 21 and attached to the top of the sludge storage tank 11. A support plate 35 is fixedly connected to the rotating cover plate 34. A second motor 36 is fixedly installed on the support plate 35. The output end of the second motor 36 is fixedly connected to a second gear 37 that meshes with the gear plate 42.

[0022] Specifically, such as Figure 3 and Figure 5 As shown, the dredging assembly 5 includes a suction pump 51 fixedly connected to the mounting platform 14. The suction pump inlet end is connected to and communicates with a connecting hose 52, and the outlet end is connected to and communicates with a discharge pipe 54. The end of the connecting hose 52 away from the suction pump inlet end is connected to and communicates with a discharge pipe 53. One end of the discharge pipe 53 passes through the connecting plate 46 and is fixedly connected to the connecting plate 46.

[0023] Therefore, in actual use, the operator turns on the first motor 31 to rotate it, which drives the first gear 32 at the output end of the first motor 31 to mesh with the gear ring 33 on the outside of the column 21 in the fixed pipe assembly 2, and drives the column 21 to rotate above the sludge storage box 11 through the bearing seat. When the column 21 rotates, its top fixing block 22 drives the fixing sleeve 23 to rotate synchronously, and then drives the sludge inlet pipe 53 to rotate around the axis of the column 21 through the moving rod assembly 4. According to the direction of the sludge removal area, observe the position of the sludge inlet pipe 53, and turn off the first motor 31 when it turns to the target sludge area to complete the sludge removal direction adjustment. The sludge removal needs in different directions can be covered without moving the entire device.

[0024] Then, the second motor 36 of the adjustment component 3 is turned on and rotated. The second gear 37 at the output end of the second motor 36 meshes with the toothed plate 42 on the L-shaped moving rod 41 in the moving rod assembly 4. The L-shaped moving rod 41 slides along the inner side of the fixed sleeve 23. The limiting block 25 and the sliding groove 43 cooperate to prevent the L-shaped moving rod 41 from sliding out of the fixed sleeve 23. When the L-shaped moving rod 41 extends, it drives the silt inlet pipe 53 to extend away from the device through the mounting plate 44. When it shortens, it drives the silt inlet pipe 53 to move closer to the device, thereby adjusting the silt removal distance to adapt to different operating radius requirements from the edge of the riverbank to the center of the river. Then the operator starts the cylinder 45 of the moving rod assembly 4. The piston rod of the cylinder 45 drives the sludge inlet pipe 53 to rise and fall vertically through the connecting plate 46. When the piston rod extends, the sludge inlet pipe 53 is inserted into a deeper layer of sludge. When the piston rod retracts, the sludge inlet pipe 53 is lifted up and removed from the shallow sludge. The sludge dredging depth is precisely controlled by the stroke of the cylinder 45. It can be dynamically adjusted according to the thickness of the sludge layer, such as surface mud, middle sludge, and deep hard mud, to avoid over-dredging or incomplete sludge dredging.

[0025] After adjustment, the operator turns on the suction pump 51 of the sludge removal component 5. The suction pump 51 generates negative pressure through the connecting hose 52, and the sludge mixture is sucked in through the inlet pipe 53. The sludge is transported to the sludge storage tank 11 through the connecting hose 52, the suction pump 51, and the outlet pipe 54. It is then collected through the sludge inlet 12 at the top of the sludge storage tank 11. During the operation, the flexible design of the connecting hose 52 can adapt to the extension and rotation of the L-shaped moving rod, avoiding pipe bending and blockage.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
