The outside of the turntable is connected with a rotating rod. The outside of the rotating rod is connected with stirring rods, and the stirring rods are evenly distributed. The left side of the outer wall of the support base is fixedly connected with a fixing frame. Insertion holes are opened in both the fixing frame and the support frame, and inserting rods are connected to the insertion holes in an inserted manner.

[0004] In the above prior art, although there will be no blockage phenomenon, it is time-saving and labor-saving during dredging, thus reducing the difficulty of dredging. However, water and silt are stored together, reducing the storage space and the carrying capacity of silt. At the same time, a large amount of water body is contained in the silt. If this part of the water body is not returned to the river, it will be a waste of water resources. Content of the Utility Model

Embodiment 1:

[0024] Refer to Figure 1 , a dredging device for water conservancy projects, including a base 1, a collection box 2 is fixedly installed on the top of the base 1, a sludge pump 15 fixedly installed on the upper surface of the base 1 is arranged on one side of the collection box 2, an L-shaped plate 16 fixedly installed on the surface of the base 1 is arranged on one side of the sludge pump 15, the outer end surface of the L-shaped plate 16 is threadedly connected with a threaded rod 17, the bottom of the threaded rod 17 is rotatably connected with a vertical cylinder 19, a slide groove for the vertical cylinder 19 to slide is opened on one side of the L-shaped plate 16, the top of the threaded rod 17 is fixedly connected with a turntable 18, the bottom of the vertical cylinder 19 is fixedly connected with a filter head 20 for filtering waterweeds or plastic bags in the water channel, and a telescopic pipe 21 is communicated between the vertical cylinder 19 and the sludge pump 15. During use, rotate the turntable 18 to make the threaded rod 17 rotate, so as to drive the vertical cylinder 19 to move up and down, so as to be suitable for water channels with different depths.

[0025] Refer to Figures 2 - 6, a rotating base 3 is fixedly installed on the inner wall of the bottom of the collection box 2. The upper end surface of the rotating column of the rotating base 3 is fixedly connected with a centrifugal cylinder 4 through bolts. The centrifugal cylinder 4 is detachably arranged. Block pads 5 are symmetrically and fixedly installed on the inner wall of the cavity of the centrifugal cylinder 4. A filter box 6 used in cooperation with the centrifugal cylinder 4 is placed on the upper surface of the block pads 5. The filter box 6 is fixed to the centrifugal cylinder 4 through bolts, and is used for filtering small particle impurities in the sludge to prevent clogging of the filter cloth 14. The filter box 6 is detachably arranged, and a vibration motor 7 is fixedly installed on the top of the filter box 6, which is used to vibrate the filter box 6 to accelerate the falling speed of the sludge and improve work efficiency.

[0026] A plurality of filter holes 13 are formed in the cylinder body of the centrifugal cylinder 4, and a filter cloth 14 is arranged in the inner wall of the cylinder body of the centrifugal cylinder 4. The filter cloth 14 seals the filter holes 13. The cooperation of the filter holes 13 and the filter cloth 14 enables the sludge to remain in the centrifugal cylinder 4 and the water to be thrown out, so as to separate the sludge from the water.

[0027] Reference Figures 1 - 4 , a gear ring 8 is arranged on the outer wall of the top of the centrifugal cylinder 4. The centrifugal motor 11 is fixedly connected to the top of the collection box 2. The output end of the centrifugal motor 11 penetrates through the top of the collection box 2 and is fixedly connected with a gear 12. The gear 12 meshes with the gear ring 8. When the centrifugal motor 11 rotates, it drives the gear 12 to rotate. Through the cooperation of the gear ring 8, the centrifugal cylinder 4 rotates, so as to separate the sludge from the water. Drain pipes 22 communicating with the outside are installed on both sides of the collection box 2.

[0028] Reference Figure 2 , an outer surface above the centrifugal cylinder 4 is fixedly connected with a slider 9. A chute 10 used in cooperation with the slider 9 is arranged on the inner wall of the collection box 2. The slider 9 slides inside the chute 10, so that the centrifugal cylinder 4 maintains its stability when rotating and centrifuging.

[0029] Further, while the sludge pump 15 pumps the sludge into the filter box 6, the centrifugal motor 11 is rotated. The vibration motor 7 vibrates the filter box 6 to enable the sludge to complete rapid filtration and fall. While the centrifugal motor 11 rotates, it drives the gear 12 to rotate. When the gear 12 rotates, through the cooperation of the gear ring 8, the centrifugal cylinder 4 rotates, so that the sludge is centrifuged to throw out the water, which is discharged from the drain pipe 22. The use of the filter cloth 14 leaves the sludge in the centrifugal cylinder 4. After the work is completed, it is taken out for treatment and the water is discharged, which increases the space utilization rate, improves the load capacity of the collected sludge, so that more sludge can be collected and the work efficiency is accelerated. Embodiment 2:

[0030] Reference Figure 1 and 6The two ends of the base 1 are provided with symmetrical bidirectional screw rods 24 and guide columns 25. The guide columns 25 are fixedly connected to one side near the inner wall of the base 1. The bidirectional screw rods 24 are installed on the outer side of the guide columns 25 and rotate with the base 1. The two side surfaces of the bidirectional screw rods 24 are threadedly connected with centrally symmetrical movable blocks 26. The outer side of the movable block 26 is fixedly connected to the telescopic plate 27. The telescopic plate 27 passes through the side of the base 1 and slides together. The middle parts of the two bidirectional screw rods 24 are connected by a transmission assembly 28. The transmission assembly 28 consists of a synchronous wheel and a synchronous belt fixedly connected to the middle of the bidirectional screw rods 24 respectively. An adjusting motor 29 is fixedly installed on the outer side of the base 1. The output end of the adjusting motor 29 is fixed to one end of the bidirectional screw rod 24. When in use, the adjusting motor 29 drives the bidirectional screw rod 24 to rotate, and the movable block 26 is limited by the guide column 25, so that the two movable blocks 26 can move relative to each other, thereby driving the telescopic plate 27 to be retracted in the base 1.

[0031] refer to Figure 6 The lower surface of the telescopic plate 27 is fixedly connected to a column 30, and a walking wheel 31 is rotatably installed on the bottom of the column 30.

[0032] The distance between the two running wheels 31 can be adjusted by telescoping the telescopic plate 27 , so that the running wheels 31 can be used in canals of different widths.

[0033] refer to Figure 1 The upper surface of the base 1 away from the vertical cylinder 19 is fixedly connected with an armrest 23, and telescopic rods are provided at both ends of the armrest 23. The telescopic rods are used in conjunction with the telescopic plates 27 to facilitate the movement of the equipment in channels of different widths.

[0034] Furthermore, when adjusting the distance between the running wheels 31 according to the width of the canals, the adjusting motor 29 is controlled to rotate, and the adjusting motor 29 drives the bidirectional screw rod 24 to rotate. The movable block 26 is limited by the guide column 25, so that the two movable blocks 26 can move relative to each other, thereby driving the telescopic plate 27 to be able to be telescoped in the base 1, and then adjusting the distance between the two running wheels 31 to make it suitable for use in canals of different widths.
