When cleaning the silt in the box culvert, the dredging equipment is usually inserted into the box culvert. The dredging equipment has a pump body, and the inlet end of the pump body is connected The outlet end of the pump body is connected to the silt conveying pipe. The silt conveying pipe extends to the river bank and is connected to the collecting truck. The pump body sucks the silt in the box culvert from the silt suction piece to the silt conveying pipe and passes it through the silt conveying pipe. The tube is sent to the collecting truck.

The piston end of the fourth telescopic rod 38 is in contact with the position adjustment The tubes 25 are connected, and the axial direction of the fourth telescopic rod 38 is parallel to the axial direction of the third section 3013 .

When the fourth telescopic rod 38 is retracted, the end of the positioning tube 25 does not exceed the end of the third section 3013 away from the second section 3012 . When the fourth telescopic rod 38 is extended, the end of the positioning pipe 25 away from the second section 3012 extends from the end of the third section 3013, so that the overall lengths of the suction pipe 301 and the positioning pipe 25 can be adjusted according to the thickness of the mud.

Referring to FIG. 1 , optionally, in some embodiments, a first sensor is provided on the inner wall of the middle part of the storage box 101 , and a second sensor is provided on the inner wall of the storage box 101 near the top of the storage box 101 . When the gravel is accumulated in the storage box 101 and is close to the first sensor, the first sensor transmits a signal to the first suction pump 30, and the amount of mud sucked by the first suction pump 30 increases. When the gravel is discharged, When the accumulation in the material box is close to the second sensor, the second sensor transmits a signal to the first silt suction pump 30, the first silt suction pump 30 stops suctioning silt, and the silt suction machine moves to the river bank to dump out the gravel.

The implementation principle of an intelligent underwater box culvert pipeline silt suction machine in the embodiment of the present application is as follows: driving the entire silt suction machine to move underwater through the crawler 102, and through the relative displacement of the positioning pipe 25 and the silt suction pipe 301, and The rotation of the sludge suction pipe 301 adjusts the position of the sludge suction pipe 301 to suck sludge. When the sludge suction pipe 301 absorbs sludge, the first telescopic rod 31 drives the extension pipe 302 to move downward, opens the opening and closing seat 8 and extends into the inner cylinder 202 to transfer the sludge to the inner cylinder 202. When the sludge reaches a certain amount, the extension tube 302 is extended. The tube 302 moves upward, and the opening and closing seat 8 is acted by the torsion spring 34 to close the opening 7 . Then, the rotating motor 27 starts to drive the inner cylinder 202 to rotate, and at the same time the second sludge suction pump 32 starts, so that the sludge is thrown into the sludge chamber 6 through the sludge discharge hole 5 and the communication hole 19, and the sludge in the sludge chamber 6 is transported Pipe 4 sucks and transports it to the shore for collection.

After the inner cylinder 202 rotates for a certain period of time, the second telescopic rod 35 drives the blocking seat 10 to move downward to open the first outlet 9, so that the sleeve 18 rotates until the communication hole 19 is offset from the opposite sludge discharge hole 5. At this time, the third The three telescopic rods 36 drive the gate 13 to open the second outlet 12, and the suction pump 23 is started. The gate 13 rotates and drives the closing seat 15 to open the inlet 11 of the storage box 101. The gravel in the inner cylinder 202 passes through the third outlet in sequence. The first outlet 9, the second outlet 12 and the inlet 11 enter the storage box 101 for collection. And when the suction pump 23 is running, the second sludge suction pump 32 is still in operation. After the gravel falls, the blocking seat 10, the gate 13 and the closing seat 15 are reset, the first outlet 9, the second outlet 12 and the inlet 11 are closed, the suction pump 23 is stopped, and then the above steps are repeated to absorb and decompose the sludge. .

The above are all preferred embodiments of the present application, and do not limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application shall be covered by the protection scope of the present application. Inside.
