Description

Technical Field

[0001] This utility model belongs to the field of dredging technology, specifically a dredging device for water conservancy projects. Background Technology

[0002] During the operation of water conservancy projects, a large amount of silt is generated. This silt mainly originates from sediment carried by water flow, erosion material from riverbanks, and sediment produced by underwater biological activity. As silt accumulates, it reduces the water storage capacity of rivers and reservoirs, affecting flood control safety. In irrigation projects, silt clogs channels, reducing the water flow area and lowering irrigation efficiency. In hydroelectric power projects, silt entering turbines and other equipment can cause wear and tear, reducing power generation efficiency and even leading to equipment failure. In navigation projects, silt accumulation can shallow waterways, affecting normal navigation. Therefore, to ensure the normal operation of water conservancy projects and to realize their intended benefits, regular dredging operations using dredging equipment are necessary.

[0003] Most existing dredging devices have relatively fixed suction head angles, making it difficult to adjust them flexibly according to actual working conditions. When the suction head operates at an unsuitable angle, incomplete dredging is likely to occur. For example, in areas with steep riverbed slopes or uneven silt distribution, the suction head cannot closely adhere to the silt layer, resulting in some silt residue, reducing dredging efficiency, and long-term accumulation affecting the benefits of water conservancy projects. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a dredging device for water conservancy projects. This device solves the problems of the fixed angle of the suction head in existing dredging devices, which makes it difficult to adjust flexibly according to actual working conditions. The suction head cannot closely adhere to the silt layer, resulting in some silt residue, reduced dredging efficiency, and long-term accumulation that affects the benefits of water conservancy projects.

[0005] A dredging device for water conservancy projects includes a dredging vessel assembly, a dredging head mechanism, a suction assembly, and a sludge storage tank assembly.

[0006] The dredging vessel assembly includes a dredging vessel body and a support frame fixedly connected to the dredging vessel body;

[0007] The suction head mechanism includes a suction head assembly rotatably connected to the support frame and a drive assembly for driving the suction head assembly to rotate.

[0008] The suction assembly and the suction head assembly are connected;

[0009] The sludge storage tank assembly is installed on the dredging vessel body and is used to collect the sludge transported by the suction assembly.

[0010] Preferably, the suction head assembly includes an outer rod rotatably connected to a support frame, an adjustment frame fixedly connected to the outer rod, a sliding groove provided on the adjustment frame, an inner rod slidably connected inside the outer rod, one end of the inner rod extending to the outside of the outer rod and fixedly connected to the suction head body, a connecting block fixedly connected to the inner rod, and a ring fixedly connected to the outside of the outer rod.

[0011] Preferably, an electric telescopic rod is also fixedly connected to the outer rod, and the output end of the electric telescopic rod is fixedly connected to the connecting block.

[0012] Preferably, the drive assembly includes a hydraulic cylinder fixedly connected to the dredging vessel body, the output end of the hydraulic cylinder being fixedly connected to a traction frame, and the traction frame being slidably connected in a groove of an adjusting frame.

[0013] Preferably, the suction assembly includes a mud pump fixedly connected to the body of the dredging vessel, with one end of the mud pump fixedly connected to the input end of the mud pump and the other end of the mud pump passing through a ring and fixedly connected to the suction head body, and the output end of the mud pump fixedly connected to the discharge pipe.

[0014] Preferably, the sludge storage tank assembly includes a sludge storage tank body fixedly connected to the sludge dredging vessel body, a filter box being embedded in the sludge storage tank body, and a water outlet pipe being fixedly connected to one end of the sludge storage tank body near the bottom, the other end of the water outlet pipe penetrating the sludge dredging vessel body.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model controls a hydraulic cylinder, whose output end pushes or pulls the traction frame. The traction frame slides in the groove of the adjusting frame, thereby driving the outer rod to rotate around the support frame. In this way, the angle of the suction head body can be adjusted so that it can approach the silt layer at the best angle according to the distribution of silt and the operation requirements, thereby improving the dredging efficiency and effect.

[0017] 2. This utility model uses a filter box to intercept solid particles and some impurities in the silt, while water permeates into the silt storage tank body through the filtration effect of the filter box. This design achieves preliminary solid-liquid separation of the silt, which facilitates the subsequent centralized treatment and transportation of solid silt, and also reduces the burden of subsequent drainage treatment. The water filtered by the filter box enters the silt storage tank body, and is then discharged to the designated drainage area through the outlet pipe. In this way, water resources can be recycled and reused, reducing the impact on the surrounding environment, and also reducing the interference of dredging operations on the water body of the water conservancy project itself, which is conducive to maintaining the ecological balance of the water conservancy project.

[0023] 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.

[0024] like Figures 1 to 4 As shown:

[0025] Example 1: This utility model provides a dredging device for water conservancy projects, including a dredging boat assembly 1, a dredging head mechanism 2, a suction assembly 3, and a sludge storage box assembly 4;

[0026] The dredging vessel component 1 includes a dredging vessel body 11 and a support frame 12 fixedly connected to the dredging vessel body 11;

[0027] The suction head mechanism 2 includes a suction head assembly 21 rotatably connected to the support frame 12 and a drive assembly 22 for driving the suction head assembly 21 to rotate;

[0028] The suction assembly 3 and the suction head assembly 21 are connected;

[0029] The sludge storage box assembly 4 is installed on the dredging vessel body 11 and is used to collect the sludge transported by the suction assembly 3.

[0030] Specifically, the suction head assembly 21 includes an outer rod 211 rotatably connected to the support frame 12, an adjusting frame 212 fixedly connected to the outer rod 211, a sliding groove 213 provided on the adjusting frame 212, an inner rod 214 slidably connected inside the outer rod 211, one end of the inner rod 214 extending to the outside of the outer rod 211 and fixedly connected to the suction head body 215, a connecting block 216 fixedly connected to the inner rod 214, and a ring buckle 217 fixedly connected to the outside of the outer rod 211.

[0031] Specifically, an electric telescopic rod 218 is also fixedly connected to the outer rod 211, and the output end of the electric telescopic rod 218 is fixedly connected to the connecting block 216.

[0032] Specifically, the drive assembly 22 includes a hydraulic cylinder 221 fixedly connected to the body 11 of the dredging vessel. The output end of the hydraulic cylinder 221 is fixedly connected to a traction frame 222, which is slidably connected in the groove 213 of the adjusting frame 212.

[0033] Specifically, the suction assembly 3 includes a mud pump 31 fixedly connected to the body 11 of the dredging vessel. The input end of the mud pump 31 is fixedly connected to one end of the mud inlet pipe 32. The other end of the mud inlet pipe 32 passes through the ring buckle 217 and is fixedly connected to the suction head body 215. The output end of the mud pump 31 is fixedly connected to the mud outlet pipe 33.

[0034] As can be seen from the above, the power unit on the dredging vessel 11 is started, and the entire dredging device is driven to the location of the water conservancy project where dredging operations are required. After reaching the designated dredging area, the power unit is turned off, so that the dredging vessel 11 is stabilized in the working position. At this time, the dredging vessel 11 relies on its own buoyancy and stability to remain on the water surface, providing a stable working platform for subsequent dredging operations. The hydraulic cylinder 221 is controlled, and the output end of the hydraulic cylinder 221 pushes or pulls the traction frame 222. The traction frame 222 slides in the slide groove 213 of the adjusting frame 212, thereby driving the outer rod 211 to rotate around the support frame 12. In this way, the angle of the suction head body 215 can be adjusted so that it can approach the silt layer at the best angle according to the distribution of silt and the operation requirements, thereby improving the dredging efficiency and effect. For example, when facing riverbeds or reservoir bottoms with different slopes, adjusting the angle of the suction head allows the suction head body 215 to fit tightly against the silt layer, avoiding incomplete dredging or empty suction due to an unsuitable angle. This effectively improves the quality and efficiency of dredging. By controlling the electric telescopic rod 218, the output end of the electric telescopic rod 218 pushes or pulls the connecting block 216, thereby causing the inner rod 214 to extend outward or retract inward within the outer rod 211. This allows adjustment of the distance between the suction head body 215 and the silt, achieving control over the suction depth. When cleaning deeper silt, the suction head body 215 can be extended to a suitable position; while when cleaning shallow silt, the extension length of the suction head body 215 can be appropriately shortened. This flexible adjustment method can meet the cleaning needs of silt at different depths, expanding the applicability of the dredging device and improving its versatility and practicality. Start the mud pump 31. The mud pump 31 sucks the sludge from the suction head body 215 through the mud inlet pipe 32. The mud inlet pipe 32 passes through the ring buckle 217 and is connected to the suction head body 215. The ring buckle 217 can fix and protect the mud inlet pipe 32 to a certain extent, preventing the mud inlet pipe 32 from loosening or being damaged due to water flow impact or hull shaking during the suction process. Under the action of the mud pump 31, the sludge is transported along the mud inlet pipe 32 to the mud outlet pipe 33. The sludge discharged from the mud outlet pipe 33 is transported to the mud storage tank assembly 4.

[0035] Example 2: This example is basically the same as the previous example, except that the sludge storage box assembly 4 includes a sludge storage box body 41 fixedly connected to the dredging vessel body 11, a filter box 42 is embedded in the sludge storage box body 41, and one end of a water outlet pipe 43 is fixedly connected to the side of the sludge storage box body 41 near the bottom, and the other end of the water outlet pipe 43 passes through the dredging vessel body 11.

[0036] As can be seen from the above, the sludge discharged from the discharge pipe 33 is transported to the filter box 42. The filter box 42 is embedded in the sludge storage box body 41 and has a certain volume and structural strength, which can hold a large amount of sludge. Inside the filter box 42, solid particles and some impurities in the sludge are intercepted, while water permeates into the sludge storage box body 41 through the filtration effect of the filter box 42. This design realizes the initial solid-liquid separation of the sludge, which facilitates the subsequent centralized treatment and transportation of solid sludge, and also reduces the burden of subsequent drainage treatment. The water filtered by the filter box 42 enters the sludge storage box body 41 and is then discharged to the designated drainage area through the water outlet pipe 43. In this way, water resources can be recycled and reused, the impact on the surrounding environment can be reduced, and the interference of dredging operations on the water body of the water conservancy project itself can be reduced, which is conducive to maintaining the ecological balance of the water conservancy project.
