[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 2The utility model provides an embodiment of a pipeline drainage cleaning device for water conservancy projects, comprising a rotating rod 1, a drill bit 5 is fixedly connected to the end of the rotating rod 1, and the rotating rod 1 is driven by a motor to rotate the drill bit 5 to dredge the inside of the pipeline. The outer wall of the rotating rod 1 is slidably connected to an adjusting rod 2, and the outer wall of the adjusting rod 2 is hinged with a bracket 3. The adjusting rod 2 can change the angle of the bracket 3 by sliding along the outer wall of the rotating rod 1. A scraper 4 is hinged at the outer end of the bracket 3. The change of the angle of the bracket 3 will drive the position of the scraper 4 to change. The inner wall of the scraper 4 is detachably connected with a brush plate 11. The scraper 4 scrapes off the harder blockages inside the pipeline, and then the brush plate 11 is used for brushing. The inner wall of the drill bit 5 is fixedly connected to a guide rod 6. When the angle of the bracket 3 changes, the scraper 4 is prompted to slide along the outer wall of the guide rod 6, thereby controlling the extension and contraction of the scraper 4. The inner end of the guide rod 6 is fixedly connected to the outer wall of the rotating rod 1, and the outer wall of the guide rod 6 is slidably connected to the inner wall of the scraper 4. The inner wall of the rotating rod 1 is elastically connected with a buckle through a reset spring a7. The buckle assembly includes a card block 8, and the side wall of the card block 8 is provided with an inclined surface. When the adjusting rod 2 is dragged backward, it may be blocked by the side wall of the card block 8. At this time, it is necessary to manually press the card block 8 to retract the side wall plane. After that, dragging the adjusting rod 2 will cause the inner wall of the card block 8 to squeeze the inclined surface of the card block 8 so that it is completely retracted. One end of the return spring a7 is fixedly connected to the bottom end of the card block 8, and the other end of the return spring a7 is fixedly connected to the inner wall of the rotating rod 1. During the process of the card block 8 squeezing the return spring a7 to retract, the return spring a7 The elastic force generated by the deformation will give the block 8 a thrust in the opposite direction, prompting it to reset. A slot 9 is provided on the inner wall of the adjusting rod 2, and the outer wall of the block 8 is engaged with the inner wall of the slot 9. When the block 8 is inserted into the slot 9, the position of the adjusting rod 2 is fixed, thereby fixing the position of the scraper 4. A pressing plate 10 is slidably connected to the inner wall of the adjusting rod 2, and the bottom end of the pressing plate 10 is in contact with the top end of the block 8. Pressing the pressing plate 10 inwards can press the block 8 out of the slot 9, and the adjusting rod 2 can be dragged at this time.

[0031] Reference Figure 1 and Figure 3The bottom end of the brush plate 11 is fixedly connected with an insert block 12, and the inner wall of the scraper 4 is provided with a slot 13. The outer wall of the insert block 12 is plugged into the inner wall of the slot 13. The brush plate 11 can be fixed on the scraper 4 by inserting the insert block 12 into the slot 13. The inner wall of the scraper 4 is elastically connected to the limit block 15 through the return spring b14. One end of the return spring b14 is fixedly connected to the inner wall of the scraper 4, and the other end of the return spring b14 is fixedly connected to the back of the limit block 15. The limit block 15 can pressurize the return spring b14 to move outward, and When the limit block 15 is reset, the elastic force generated by the deformation of the reset spring b14 gives the limit block 15 a thrust in the opposite direction, prompting it to reset. A limit groove 16 is provided on the inner wall of the plug block 12, and the outer wall of the limit block 15 is engaged with the inner wall of the limit groove 16. When the limit block 15 is inserted into the limit groove 16, the brush plate 11 can be fixed on the scraper 4. The inner wall of the scraper 4 is slidably connected with a pull rod 17, and the inner end of the pull rod 17 is fixedly connected to the back of the limit block 15. Pulling the pull rod 17 outward can drive the limit block 15 to be pulled out of the limit groove 16.

[0032] Working principle: The motor drives the rotating rod 1 to drive the drill bit 5 into the pipeline to dredge the pipeline. At the same time, when the extension degree of the scraper 4 is adjusted according to the size of the pipeline, the pressing plate 10 is pressed inward to squeeze the reset spring a7 and retract the block 8. At the same time, the clamping connection with the clamping slot 9 is released. At this time, the adjusting rod 2 can be dragged to slide along the outer wall of the rotating rod 1, driving the angle of the bracket 3 to change, so that the scraper 4 slides along the outer wall of the guide rod 6 to clean pipelines of different sizes. When the adjusting rod 2 needs to be dragged backward, it is blocked by the clamping block 8. At this time, the clamping block 8 can be manually pressed downward to retract a part of it. At this time, the adjusting rod 2 is dragged and its inner wall squeezes the inclined surface of the clamping block 8 to completely retract it. After long-term use, the brush plate 11 is seriously worn. When the brush plate 11 needs to be replaced, the pull rod 17 is pulled outward to squeeze the reset spring b14 of the limit block 15 and withdraw it from the limit slot 16. At this time, the plug block 12 can be removed together with the brush plate 11 for replacement and maintenance.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
