Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy construction, and more specifically, to a silt-clearing device for river channel construction. Background Art
[0002] Rivers can provide space for water flow and storage, and can be used for flood discharge as well as irrigating nearby land. They play an important role in providing drainage and drought resistance. However, after long-term use, mud and other materials will accumulate inside the river to form silt. Excessive silt will raise the riverbed and affect the use of the river. Therefore, the river needs to be dredged regularly.
[0003] Common dredging equipment is relatively simple, just a simple suction device that can suck away the silt in the river channel. However, in the river channel, some silt will solidify due to a long time and internal material reasons. The solidified silt material becomes hard, and it is difficult to clean the solidified silt by suction alone; and there will be some large lumps in the silt. After entering the pipe of the suction equipment, because the silt is relatively viscous, it is easy to accumulate and clog in the pipe, causing the pipe to be blocked and affecting the dredging work; and the sucked silt will be mixed with a large amount of river water. Sometimes when facing a larger river channel, the dredging equipment needs to be set on a floating device, and moved by the floating device away from the shore. The collected silt containing a large amount of river water is not convenient to handle. Utility Model Content

[0048] In summary, when the overall device is in use or running:
[0049] When the equipment is used for work, the dredging boat 1 supports and drives each device to move. Under the connection of the connecting frame 3, the dredging shovel 4 moves with the dredging boat 1, and the silt in the river channel is cleaned by the dredging shovel 4. During the cleaning, if the silt in the river channel is hard, the pumping pipe 7 is placed in the water, and the pumping pump 6 is started. Under the action of the pumping pump 6, river water is pumped through the pumping pipe 7, and the river water flows through the pumping pump 6 and supplies water to the sprinkler 5 through the water supply pipe 8. Under the support of the mounting frame 26, the operation of the integration box 27 and the high-pressure water gun 28 is guaranteed to be stable. The water supply pipe 8 supplies water to the integration box 27, and water is provided to each high-pressure water gun 28 through the integration box 27, so that water flows out from the high-pressure water gun 28, impacting the silt at the front end of the dredging shovel 4, and softening the hardened silt, which is convenient for the operation of the dredging shovel 4. The silt shovel 4 has an inclined shape. The sludge is lifted up and moved along the surface of the dredging shovel 4. At this time, the sludge pump 14 and the driving motor 12 are started. Negative pressure is provided by the sludge pump 14. Under the guidance of the sludge suction pipe 13, suction is generated at the sludge collecting tank 9 to absorb the shoveled sludge. The crushing rollers 10 are provided with two or more groups and cooperate with each other. When the sludge enters the sludge collecting tank 9, it will pass between the crushing rollers 10. Under the action of the driving motor 12, the crushing rollers 10 rotate and drive the crushing teeth 11 to rotate, so as to crush the incoming sludge, so that large pieces of sludge are dispersed into small pieces of sludge and then enter the sludge collecting tank 9. Under the guidance of the sludge suction pipe 13, multiple shunt pipes 30 are connected with different silt outlets 31 to absorb the sludge in the sludge collecting tank 9 from multiple positions to ensure the discharge speed of the sludge. The sludge flows along the shunt pipes 30, and after merging, it flows along the main pipe 29 to move to the sludge box 2 above.
[0050] After the sludge is sucked out of the river channel, the sludge flows from the main pipe 29 through the sludge pump 14 into the treatment box 15, where it is treated. The stirring motor 18 is started, and the stirring shaft 19 is driven to rotate by the stirring motor 18. The stirring shaft 19 drives the stirring blade 20 to rotate, so as to stir the sludge in the treatment box 15 and speed up the treatment of the sludge. The electric heating pipe 22 is started, and the electric heating pipe 22 in the heat pipe groove 21 works. The temperature is transferred to the sludge through the transfer of the temperature conduction plate 23, so as to further speed up the treatment of the internal moisture. A large amount of water entering is discharged, and the sludge in the treatment box 15 is blocked by the filter screen 24, allowing only water to flow out from the drain port 16, and the control valve 25 on the discharge pipe 17 is closed, so that the sludge remains in the treatment box 15. After the treatment is completed, the control valve 25 is opened, and the treated sludge is discharged through the discharge pipe 17 and enters the sludge box 2. After the sludge enters the sludge box 2, the layered filter screen 32 provides a separation effect, filters the treated sludge, and leaves larger particles such as stones in the upper part of the sludge box 2, and the rest of the sludge is collected in the lower part of the sludge box 2.
