[0002] A water conservancy project is a general term for various engineering constructions built to control, utilize, and protect surface and underground water resources and the environment. Water conservancy projects mainly study the basic knowledge and skills in aspects such as engineering hydrology, water conservancy engineering survey, hydraulic reinforced concrete, hydraulic structures, engineering drawing, etc., and conduct engineering planning and design, on-site construction, engineering budget, and maintenance and repair of water conservancy equipment in the field of water conservancy projects. For example: building different types of hydraulic structures such as dams, dikes, spillways, sluice gates, channels, aqueducts, raft channels, fishways, etc., and water conservancy projects need to clean the silt at the bottom of the water.

[0003] Currently, for the existing dredging devices in water conservancy projects, during use, due to the fixed length of the connecting rod being inconvenient and difficult to adjust, the dredging head is at a fixed depth, making it inconvenient to adjust the dredging head according to the river depth. Moreover, the range for the existing dredging head to extract silt is small, resulting in low dredging efficiency. For this reason, we propose a dredging device for water conservancy projects.

Electric push rods 11 are fixedly embedded on both sides of the bottom of the floating base 1. The ends of the electric push rods 11 are fixedly installed with a collection hood 12. The collection hood 12 surrounds one side of the silt cleaning head 10 and is fixedly connected to the silt cleaning head 10 at the top.

[0021] Specifically, a clear water tank 6 is provided on the other side inside the collection box 2. A partition board 4 is provided between the clear water tank 6 and the collection groove 3. A filter screen 5 is fixedly embedded on the inner side of the bottom end of the partition board 4. The collection groove 3 is communicated with the inner bottom end of the clear water tank 6 through the filter screen 5.

[0022] Specifically, a drainage pump 13 is fixedly installed at one end of the collection box 2 near the clear water tank 6. One end of the drainage pump 13 extends to the outside of one end of the floating base 1 through a conduit. The other end of the drainage pump 13 extends to the inside of the clear water tank 6 through a provided second telescopic pipe 14.

[0023] Specifically, a slide groove 16 is opened on the inner side wall of one side of the clear water tank 6. A slide block 17 is provided inside the slide groove 16. A floating board 15 is fixedly provided on one side of the slide block 17 extending outside the slide groove 16. The bottom end of the second telescopic pipe 14 passes through the floating board 15 and extends to the bottom of the floating board 15.

[0024] Specifically, a silt discharge pipe 19 is provided on one side of the inner bottom surface of the collection tank 3. The silt discharge pipe 19 extends to the outside of the collection box 2, and a solenoid valve 20 is provided at the end of the silt discharge pipe 19.
