[0035] Embodiment 1:

[0036] As Figure 1 and Figure 2 shown, this embodiment provides a dredging device for water conservancy projects, including a fixing plate 6, a first suction pipe 1, a second suction pipe 3, a tee joint 2, a motor 5, a filter cage 4 and a mud crushing assembly; wherein, the mud crushing assembly includes a mud crushing blade 7 and a rotating shaft 8 fixedly connected to the mud crushing blade 7.

[0037] The first suction pipe 1 is installed above the fixing plate 6; the second suction pipe 3 is installed below the fixing plate 6. The motor 5 is arranged above the second suction pipe 3.

[0038] One end of the second suction pipe 3 is communicated with the first suction pipe 1 through the tee joint 2.

[0039] The other end of the second suction pipe 3 is connected to the filter cage 4, and the filter cage 4 is connected to the second suction pipe 3 by means of screw fixation. The mud crushing blade 7 is placed in the filter cage, and the rotating shaft 8 is connected to the output shaft of the motor 5 through the inner cavity of the second suction pipe and the tee joint 2. Among them, the mud crushing blade 7 adopts multi-blade blades, and the length of the rotating shaft is set according to the length of the second suction pipe. For the clarity of the drawings, the length of the rotating shaft is not shown in the drawings.

[0040] Among them, it should be noted that one end of the first suction pipe 1 far from the tee joint 2 is connected to the input interface of the suction pump.

[0041] When the present utility model is in use, the filter cage is placed in the silt, and the motor is started, so that the rotation of the motor drives the rotation of the rotating shaft of the mud crushing assembly, and then the mud crushing blade of the mud crushing assembly rotates to crush the silt sucked into the filter cage, and the crushed silt is conveyed through the second suction pipe, the tee joint and the first suction pipe. By setting a filter cage at one end of the second suction pipe, it effectively prevents large pieces of silt or other large pollutants from being sucked into the suction pipe and blocking the pipeline. In addition, by setting a mud crushing assembly, the silt sucked into the filter cage is further crushed, further avoiding the blockage of the suction pipe by silt and improving the work efficiency.

[0042] Embodiment 2:

[0043] The difference between this embodiment and Embodiment 1 is that as Figure 3 and Figure 4As shown in the figure, the dredging device for the water conservancy project further includes a monitoring device 9 provided on the fixing plate 6 and a wireless flow velocity sensor 15 provided on the inner wall of the second suction pipe 3.

[0044] The monitoring device 9 includes a housing 10. A display module 11, an alarm 12 and a control interface 13 are provided on the housing 10. A processor 16 and a wireless communication module 14 are provided inside the housing 10.

[0045] The wireless flow velocity sensor 15 is connected to the processor 16 through the wireless communication module 14, so as to send the detected flow velocity of the silt in the second suction pipe 3 to the processor 16 through the wireless communication module 14.

[0046] The processor 16 is connected to the motor 5 via the control interface 13 through a control line to control the running speed of the motor 5.

[0047] The display module 11 is connected to the processor 16 to display the flow velocity of the silt received by the processor 16. Among them, the display module 11 adopts a touch display. The display module 11 is also used to input the setting parameters of the monitoring device 9, such as the silt flow velocity threshold and the motor running speed.

[0048] The processor 16 is connected to the alarm 12 to control the alarm 12 to give an alarm.

[0049] When this embodiment is in use, the setting parameters of the monitoring device, such as the silt flow velocity threshold and the motor running speed, are input in advance through the display module. Then, the flow velocity of the silt in the suction pipe is detected by the wireless flow velocity sensor, and the detected silt flow velocity is sent to the processor through the wireless communication module. The processor displays the silt flow velocity on the display module, so that the on-site staff can understand the flow situation of the silt in the suction pipe in real time, and take timely measures when the flow velocity slows down. At the same time, the processor controls the alarm to give an alarm based on the silt flow velocity and the input silt flow velocity threshold to remind the on-site staff, so as to avoid damage to the equipment caused by silt blockage. In addition, the motor speed can also be input through the display module according to actual needs, so as to set the rotation speed of the mud-breaking component, such as increasing the mud-breaking frequency and decreasing the mud-breaking frequency.

[0050] By displaying the silt flow velocity in real time and giving an alarm according to the silt flow velocity in this embodiment, the damage caused by silt blockage to the suction pipe or other equipment is effectively avoided, and the staff can take timely measures, which also helps to improve the work efficiency to a certain extent. And the mud-breaking rate of the virtual component can be adjusted according to actual needs, which also effectively avoids blockage to a certain extent.

In particular, for the terminal embodiments, since they are basically similar to the method embodiments, the description is relatively simple. For the relevant parts, reference can be made to the description in the method embodiments.

The components shown as units may or may not be physical units, that is, they may be located in one place or distributed to multiple network units. Some or all of the units can be selected according to actual needs to achieve the purpose of the solution of this embodiment.
