DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figure 1 shown, the dredging device for water conservancy projects in this embodiment includes a truss, a vertical frame 1, a longitudinal moving mechanism 2, a transverse moving mechanism 3, a mud stirring mechanism 4, and a silt discharge pipe 5. The truss spans across the river channel and is arranged above the water surface of the river channel. The vertical frame 1 is arranged at both ends of the truss for supporting the truss, and the vertical frame 1 is located above the river bank of the river channel. The longitudinal moving mechanism 2 is arranged at the bottom of the vertical frame 1 and is connected to the vertical frame 1 for driving the vertical frame 1 and the truss to move along the length direction of the river channel. The transverse moving mechanism 3 is arranged on the truss and moves along the truss. The mud stirring mechanism 4 is arranged below the transverse moving mechanism 3 in a liftable manner and is connected to the transverse moving mechanism 3. One end of the silt discharge pipe 5 extends into the mud stirring mechanism 4, the middle part is connected to the transverse moving mechanism 3, and the other end extends to the river bank outside the truss. A sludge pump 6 is arranged on the silt discharge pipe 5.

[0027] In this embodiment, the truss includes a main frame body 11, an extension frame 12, and a docking head 13. In order to adapt to the width of the river channel, the extension frame 12 can be selectively arranged at one end or both ends of the main frame body 11, and the number of extension frames 12 is also selected according to actual needs. The main frame body 11 and the extension frame 12, the extension frame 12 and the vertical frame 1, and the main frame body 11 and the vertical frame 1 are all connected through the docking head 13. A cross bar 14 adapted to the main frame body 11 and the extension frame 12 is fixed on one side of the upper end of the vertical frame 1. As Figure 2 shown, the docking head 13 includes a docking plate and docking bolts. The docking plate is fixed at both ends of the main frame body 11 and the extension frame 12 and at the end of the cross bar 14 away from the vertical frame 1, and adjacent docking plates are connected through docking bolts.

[0028] In this embodiment, a transverse moving track 7 is fixedly connected to the bottom of the truss along the length direction. The transverse moving mechanism 3 is provided with a track wheel 301 adapted to the transverse moving track 7 and a transverse moving motor 302 for driving the track wheel 301 to rotate. Specifically, the transverse moving track 7 is an I-shaped track and includes multiple track segments. Two track segments are fixedly arranged side by side at the bottom of the main frame body 11 and the extension frame 12, and the ends of the track segments are flush with the outer side surface of the docking plate. In this way, when the main frame body 11 and the extension frame 12 are connected through the docking head 13, adjacent track segments can be spliced into the entire transverse moving track 7.

[0029] In this embodiment, as Figure 3As shown in the figure, the lateral movement mechanism 3 includes a lateral movement vehicle frame 303 sleeved outside the truss and the lateral movement track 7. The track wheels 301 are installed inside the lateral movement vehicle frame 303, and the lateral movement motor 302 is installed outside the lateral movement vehicle frame 303 and is in transmission connection with the track wheels 301. A lifting assembly 8 for driving the mud stirring mechanism 4 to lift is installed on the bottom surface of the lateral movement vehicle frame 303.

[0030] In this embodiment, as Figure 4 shown, the mud stirring mechanism 4 includes a mud stirring cover 401, a mud stirring roller 402 and a mud stirring motor. The lower end of the mud stirring cover 401 is open and has a trapezoidal structure with a smaller upper part and a larger lower part. The mud stirring roller 402 is arranged inside the mud stirring cover 401. The mud stirring motor (not shown in the figure) is installed outside the mud stirring cover 401 and is in transmission connection with the mud stirring roller 402. One end of the silt discharge pipe 5 penetrates through the top surface of the mud stirring cover 401 and extends into the mud stirring cover 401. The lifting assembly 8 is specifically a winch. Two winches are symmetrically installed on the bottom surface of the lateral movement vehicle frame 303, and the suspension cables of the two winches are symmetrically connected to the outer side of the upper part of the mud stirring cover 401. As Figure 5 shown, in another embodiment, the lifting assembly 8 can be a hydraulic push rod or an electric push rod. The hydraulic push rod or the electric push rod is vertically arranged and is respectively connected to the bottom surface of the lateral movement vehicle frame 303 and the top surface of the mud stirring cover 401 at both ends.

[0031] In this embodiment, the sludge pump 6 is installed on the top surface of the lateral movement vehicle frame 303. One end of the silt discharge pipe 5 connected to the inlet of the sludge pump 6 is connected to the side surface of the lateral movement vehicle frame 303 by a pipe clamp 9. An installation plate 10 is arranged on the top surface of the vertical frame 1. One end of the silt discharge pipe 5 connected to the outlet of the sludge pump 6 is connected to the top surface of the installation plate 10 by a pipe clamp 9. Specifically, the silt discharge pipe 5 can adopt a flexible pipe; or, a first corrugated pipe is arranged on the part of the silt discharge pipe 5 between the mud stirring cover 401 and the lateral movement vehicle frame 303, and a second corrugated pipe is arranged on the part of the silt discharge pipe 5 connected to the outlet of the sludge pump 6. With such a setting, the vertical section of the silt discharge pipe 5 can adapt to the lifting of the mud stirring mechanism 4, and the horizontal section can adapt to the movement of the lateral movement mechanism 3.

[0032] In this embodiment, the longitudinal movement mechanism 2 is a single-track power transport vehicle. The single-track power transport vehicle adopts the prior art, and its structure will not be elaborated here. Other mobile vehicles can also be used instead.

[0033] The working principle of the dredging device for water conservancy projects in this embodiment is:

[0034] The truss is spanned across the river channel. Erection frames 1 are provided at both ends of the truss, and the erection frames 1 are arranged on the river banks and longitudinal movement mechanisms 2 are provided at the bottoms. The longitudinal movement mechanisms 2 move along the length direction of the river channel on the river banks, thereby driving the truss and the columns to move. The mud stirring mechanism 4 can penetrate into the river water to disperse the silt, and then the dispersed silt is discharged through the silt discharge pipe 5. A tipping truck can be parked below the port of the silt discharge pipe 5 away from the mud stirring mechanism 4, so as to discharge the silt onto the tipping truck for transfer. In the dredging device for water conservancy projects of the present utility model, by arranging the longitudinal movement mechanisms 2 on the river banks, the situation that a dredging device with a boat-shaped structure is grounded and cannot be used when the water flow in the river is small will not occur. Therefore, it is applicable to the dredging work when the water flow in the river channel is small. A transverse movement mechanism 3 is provided, so that the silt discharge pipe 5 and the mud stirring mechanism 4 can move transversely along the river channel, thereby carrying out dredging work on different transverse positions of the river channel.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
