[0020] According to actual needs, the above pipeline dredging device can be further optimized or / and improved:

[0021] Embodiment 2, as shown in the attached Figure 1 、 2 As shown, this embodiment is a further optimization of the above embodiment. The support frame includes a front arm 6 and a rear arm 7. The front arm 6 is in a U shape with an opening downward. The left part of the lower end of the front arm 6 is hingedly installed on the left part of the upper end of the flange 2, and the right part of the lower end of the front arm 6 is hingedly installed on the right part of the upper end of the flange 2. A rear arm 7 is provided on the upper part of the flange 2 corresponding to the rear end position of the front arm 6. The rear arm 7 and the front arm 6 have the same structure and are symmetrically distributed. A first arc-shaped groove penetrating up and down is provided at the rear side of the upper end of the front arm 6, and a front connection thread is provided inside the first arc-shaped groove. A second arc-shaped groove penetrating up and down is provided at the front side of the upper end of the rear arm 7, and a rear connection thread is provided inside the second arc-shaped groove. The first arc-shaped groove and the second arc-shaped groove can form a connecting screw hole. A fastening mechanism capable of making the rear end of the front arm 6 and the front end of the rear arm 7 fit is provided on the right part of the front arm 6.

[0022] In this embodiment, both the front arm 6 and the rear arm 7 are in a U shape with an opening downward and the width gradually increases from top to bottom.

A rear connection hole 12 penetrating through the front and rear is opened on the front side of the right part of the rear arm 7 corresponding to the position of the front connection hole. The fastening bolt 8 is arranged inside the rear connection hole 12, and the front end of the fastening bolt 8 passes through the front end of the front connection hole and is screwed with the fastening nut 13.

[0024] In this embodiment, through the cooperation of the fastening bolt 8 and the fastening nut 13, the rear end of the front arm 6 and the front end of the rear arm 7 can be made to fit together. Specifically, by rotating the fastening nut 13, the fastening nut 13 moves backward, and then the fastening nut 13 and the nut of the fastening bolt 8 cooperate to clamp the front arm 6 and the rear arm 7, realizing the fitting of the front arm 6 and the rear arm 7. And the setting of the fastening bolt 8 and the fastening nut 13 can limit the swing amplitude of the front arm 6 and the rear arm 7, preventing the swing amplitude of the front arm 6 and the rear arm 7 from being too large and affecting the operation of the staff. The cross-sections of the front connection hole and the rear connection hole 12 are both oblong, which can prevent the fastening bolt 8 from getting stuck in the front connection hole or the rear connection hole 12 during the swing of the front arm 6 and the rear arm 7 and affecting the swing of the front arm 6 and the rear arm 7.

[0025] Embodiment 4, as shown in the attached Figure 1As shown in the figure, this embodiment is a further optimization of the above embodiment. A sealing seat 10 is fixedly installed on the upper part of the flange 2. A stuffing box opening is provided in the center of the upper end of the sealing seat 10.

A stuffing gland 14 sleeved on the outer side of the connecting rod 1 is fixedly installed on the upper end of the sealing seat 10.

[0026] The sealing packing 9 is a known technology in the art. In this embodiment, through the cooperation of the sealing seat 10 and the sealing packing 9, the sealing of the inner opening of the flange 2 is realized, which can effectively prevent the residual liquid in the pipeline to be dredged from splashing out and hurting people during the dredging work. A stuffing gland 14 sleeved on the outer side of the connecting rod 1 is fixedly installed on the upper end of the sealing seat 10, which can squeeze the sealing packing 9 in the stuffing box opening, improve the sealing efficiency, and prevent the sealing packing 9 from being taken out of the stuffing box opening during the up and down movement of the connecting rod 1.

[0027] Embodiment Five, as shown in the appendix Figure 1 As shown in the figure, this embodiment is a further optimization of the above embodiment. A plurality of dredging nails 11 are evenly distributed on the lower end surface of the dredging head 3, and each dredging nail 11 is in a conical shape with a wider upper part and a narrower lower part.
