Description

Technical Field

[0001] This utility model belongs to the field of water conservancy engineering, and in particular relates to a dredging device for water conservancy projects. Background Technology

[0002] Water dredging refers to the process of removing sediments (such as silt, mud, and plant debris) from water bodies using manual or mechanical means to restore the flow and ecological functions of waterways, lakes, rivers, and other water bodies. The aim is to improve the drainage capacity of water bodies, prevent floods, improve water quality, or provide better navigation conditions.

[0003] However, current dredging operations typically use industrial equipment to extract silt from the bottom of the water. But because the composition of the silt is complex, it often contains a large number of stones, aquatic plants and other debris. These debris can easily clog and damage the dredging equipment, thus affecting the smooth progress of the dredging work. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a dredging device for water conservancy projects, which aims to solve the problems mentioned in the background art.

[0005] This utility model embodiment is implemented as follows: a dredging device for water conservancy projects includes a dredging vessel, a treatment device installed on the dredging vessel, a connecting pipe connected to one side of the treatment device, and a dredging assembly connected to one end of the connecting pipe. The connecting pipe includes a sludge pipe, with its two ends connected to the input port of the treatment device and the input port of the dredging assembly, respectively. The dredging assembly includes a shell, a screen plate, and a crushing unit. The side of the shell connected to the sludge pipe is configured as a funnel-shaped collecting hopper. The other side of the shell opposite the collecting hopper is movably hinged to a screen plate, which has multiple screen holes fixedly opened on its side. The crushing unit includes a waterproof motor, a drive shaft, and multiple crushing saw blades. The waterproof motor is fixedly installed on one side of the shell, and the main shaft of the waterproof motor movably passes through the side wall of the shell and extends into the shell to be fixedly connected to the drive shaft. The crushing saw blades are fixedly installed on the outside of the drive shaft in a one-to-one correspondence with the mounting bases, with one side of the crushing saw blade located inside the mounting base and extending to the outside of the shell.

[0006] As a further embodiment of this utility model: the connecting pipe also includes a return water pipe, which is bound parallel to the sludge pipe, and the two ends of the return water pipe are respectively connected to the inlet of the sludge pumping component and the outlet of the treatment equipment.

[0007] As a further embodiment of this utility model: a plurality of nozzles are fixedly connected to one side of the housing, and the nozzles are connected to the return water pipe through the internal pipe of the housing.

[0008] As a further embodiment of this utility model: two mounting seats are fixedly provided at the bottom of the housing, and a moving unit is fixedly installed on the mounting seats. The moving unit includes multiple connecting shafts, multiple moving wheels and two track rings.

[0009] As a further embodiment of this utility model: multiple connecting shafts are fixedly installed in the mounting base in parallel with each other, multiple movable wheels are symmetrically installed at both ends of the connecting shafts, and two track rings are movably fitted on the outside of the two movable wheels.

[0010] As a further embodiment of this utility model: a partition plate is fixedly installed inside the housing on one side of the crushing unit, and the partition plate is fixedly provided with holes smaller than the screen holes.

[0011] The beneficial effects of this utility model are as follows:

[0012] 1. This utility model provides a dredging device for water conservancy projects. It extracts silt from the bottom of the water through a silt pipe and a shell, and then dewaters it through a treatment device to dredge the bottom of the water. At the same time, a screen plate is set up to block stones in the silt, preventing blockage or damage to the equipment. A waterproof motor drives a crushing saw blade to crush aquatic plants and dead leaves at the bottom of the water, preventing them from entangled and clogging the screen holes. It can also extract the crushed impurities to improve the dredging effect. The movable screen plate also makes it convenient for workers to clean the inside.

[0013] 2. The water conservancy engineering dredging device provided in this embodiment of the utility model can discharge the water after the sludge is dehydrated back into the water body through the set return water pipe, and use the flow rate of the return water in conjunction with the nozzle to flush the sludge at the bottom of the water. This can disturb the sludge at the bottom of the water, making it easier for the sludge to mix with the clean water, thereby diluting it and reducing the sludge extraction resistance, thus reducing the working pressure of the treatment equipment.

[0014] 3. The water conservancy engineering dredging device provided in this embodiment of the utility model, through the set mobile unit, based on the track structure of the mobile unit, facilitates the movement of the dredging component in the silt at the bottom of the water as the dredging vessel moves and the connecting pipe is dragged, which can effectively prevent the dredging component from getting stuck in the silt and ensure the working status of the dredging component.

[0015] 4. The water conservancy engineering dredging device provided in this utility model embodiment uses a partition plate and a mounting base to further filter the extracted silt. Smaller impurities are extracted through the partition plate, while larger impurities are blocked by the partition plate on one side of the crushing unit and further crushed by the rotating crushing saw blade, thereby further improving the dredging effect.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] like Figures 1 to 4As shown, an embodiment of the present invention provides a dredging device for water conservancy projects, including a dredging vessel 1, a treatment device 2 installed on the dredging vessel 1, a connecting pipe 3 connected to one side of the treatment device 2, and a dredging assembly 4 connected to one end of the connecting pipe 3.

The crushing saw blades 433 are fixedly installed on the outside of the drive shaft 432 in a one-to-one correspondence with the mounting base 412. One side of the crushing saw blade 433 is located inside the mounting base 412 and extends to the outside of the housing 41.

[0024] In one embodiment of this utility model, the silt is extracted from the bottom of the water by the silt pipe 31 and the shell 41, and then dehydrated by the treatment equipment 2, thereby clearing the bottom of the water. At the same time, the screen plate 42 is set to block stones in the silt to prevent blockage or damage to the equipment. The waterproof motor 431 drives the crushing saw blade 433 to crush the aquatic plants and dead leaves at the bottom of the water to a certain extent, preventing them from entangled and blocking the screen holes 421. It can also extract the crushed impurities to improve the silt removal effect. The movable screen plate 42 also makes it convenient for the staff to clean the inside.

[0025] like Figure 2 and Figure 3 As shown, in another embodiment of the present invention, the connecting pipe 3 further includes a return water pipe 32, which is bound in parallel with the sludge pipe 31.

[0030] In one embodiment of this utility model, the movable unit 44 is provided, and based on the track structure of the movable unit 44, the dredging component 4 can move in the silt at the bottom of the water as the dredging vessel 1 moves and the connecting pipe 3 is dragged. This can effectively prevent the dredging component 4 from getting stuck in the silt and ensure the working state of the dredging component 4.

[0031] like Figure 2 and Figure 3 As shown, in another embodiment of the present invention, a partition plate 46 is fixedly installed inside the housing 41 on one side of the crushing unit 43, and a hole smaller than the screen hole 421 is fixedly opened on the partition plate 46.

[0032] In one embodiment of this utility model, the sludge extracted is further filtered by the partition 46 and the mounting base 412. Smaller impurities are extracted by the partition 46, while larger impurities are blocked by the partition 46 on one side of the crushing unit 43 and further crushed by the rotating crushing saw blade 433, thereby further improving the sludge removal effect.
