[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0019] As Figure 1 - Figure 2 shown, it is the first embodiment of the pipeline dredging device of the present invention.

[0020] In this embodiment, the pipeline dredging device includes: a plugging component 1; a step-by-step dredging component 2, and the step-by-step dredging component 2 includes: a reflux support member 21, a first airbag 22, a telescopic airbag 23, and a second airbag 24 that are respectively sleeved outside the reflux support member 21. The first airbag 22, the telescopic airbag 23, and the second airbag 24 are connected in sequence; a flushing cutter head 25 fastened to the end of the second airbag 24; a pressure pipe 26, and the pressure pipe 26 is arranged inside the reflux support member 21, and one end of the pressure pipe 26 is connected to the flushing cutter head 25.

[0021] Among them: The step-by-step dredging component 2 is pushed into the pipeline A from one side of the pipeline area T with siltation. The high-pressure water in the pressure pipe 26 rotates and sprays out through the flushing cutter head 25 to disperse the silt. The plugging component 1 plugs the opposite side of the pipeline A where the siltation area T exists, and the water slurry formed by the silt is discharged to the outside of the pipeline A along the reflux support member 21.

[0022] The step-by-step dredging component 2 can penetrate into the electric pipe jacking with a diameter within 200 mm. Specifically, in implementation, the step-by-step dredging component 2 includes: a reflux support member 21 with a certain supporting function and capable of discharging the water slurry formed by the silt outward, and a variety of airbags with different specifications installed outside the reflux support member 21.

[0023] Preferably, a plurality of support wheels 211 are installed outside the reflux support member 21. By setting a plurality of support wheels 211, the friction between the pipeline dredging device and the pipeline can be reduced, and thus the overall obstacle-crossing ability can be improved.

[0024] In this embodiment, the function of the airbag is: by controlling the different ventilation sequences of the plurality of airbags, the linkage dredging device can creep forward step by step in the pipeline A. The airbags in this embodiment are respectively the first airbag 22, the telescopic airbag 23, and the second airbag 24 that are connected in sequence.

[0025] Among them: The first airbag 22 and the second airbag 24 are of roughly the same specification, and the outer diameter size of the telescopic airbag 23 is respectively smaller than the outer diameter sizes of the first airbag 22 and the second airbag 24, so as to ensure that while some airbags are closely attached to the wall of the pipeline A, other airbags can cooperate to step forward or backward.

[0026] In this embodiment, after being inflated, the first airbag 22, the telescopic airbag 23, and the second airbag 24 are respectively in a cylindrical shape. By respectively controlling the ventilation sequences of the first airbag 22, the telescopic airbag 23, and the second airbag 24, the step-by-step dredging component 2 creeps and steps in the pipeline A.

[0027] For example, the first airbag 22 is controlled to be ventilated so that it supports the tube wall, and then the telescopic airbag 23 is ventilated. The inflated outer diameter of the telescopic airbag 23 is smaller than the inflated outer diameter of the first airbag 22 and the second airbag 24, respectively, so that the second airbag 24 can be pushed forward. After the second airbag 24 steps the maximum distance, the second airbag 24 is controlled to be ventilated so that it supports the tube wall, and then the first airbag 22 and the telescopic airbag 23 are deflated respectively, thereby changing the positions of the first airbag 22 and the telescopic airbag 23 in the contracted state, thereby realizing the stepping of the entire device.

[0028] It is understandable that when the entire device needs to be withdrawn from the pipeline A, the reverse steps of the above-mentioned control airbag ventilation sequence can be implemented, which will not be repeated here.

[0029] Furthermore, since the flushing blade head 25 is installed at the end of the second airbag 24, when the airbag moves in the pipe A, it can synchronously drive the flushing blade head 25 to move to the blocked area T.

[0030] Preferably, a camera 26 for observing the position of the silt is installed on the flushing blade head 25. The image obtained by the camera 26 makes it easier to understand the position of the clogging area T.

[0031] The flushing blade head 25 performs the desilting operation in the following manner: the high-pressure water in the pressurized pipe 26 causes the flushing blade head 25 to rotate at a high speed, thereby stirring up the silt at the clogging area T.

[0032] Furthermore, the function of the blocking component 1 is to block the other side of the pipe A opposite to the blocked area T, so that the water slurry stirred by the sludge is discharged to the outside of the pipe A along the reflux support 21.

[0033] During implementation, the blocking assembly 1 includes: a driving wheel frame 11 and a blocking airbag 12 installed on the driving wheel frame 11, wherein: the driving wheel frame 11 links the blocking airbag 12 to move to the other side of the blocked area T and blocks the pipeline A.

[0034] The blocking airbag 12 is cylindrical after being inflated. During implementation, the wheel frame 11 is driven to support the pipe wall, and then the suspended blocking airbag 12 is inflated so that the blocking airbag 12 supports the pipe wall, thereby implementing blocking.

[0035] Preferably, the blocking assembly 1 further comprises: a recovery cable 13 connected to the driving wheel frame 11 .

[0036] Preferably, the driving wheel frame 11 at least includes a plurality of telescopically foldable driving wheels 111. The plurality of driving wheels 111 can reduce the friction between the blocking airbag 12 and the pipeline, thereby improving the ability of the blocking component 1 to enter and exit the pipeline A.

[0037] In the specific implementation of the pipeline dredging device in this embodiment, the device is pushed to move rapidly in pipeline A by the reflux support member 21. After reaching a position where it cannot be pushed forward continuously, by controlling the different ventilation sequences of multiple airbags, the linkage dredging device can creep forward step by step in pipeline A. For example, control the first airbag 22 to ventilate, so that it supports the pipe wall, and then make the telescopic airbag 23 ventilate, so that the second airbag 24 can be pushed forward. After the second airbag 24 steps the maximum distance, control the second airbag 24 to ventilate, so that it supports the pipe wall, and then make the first airbag 22 and the telescopic airbag 23 deflate respectively, so that the whole device moves forward.

[0038] Observe the position of the sediment through the camera 26. The high-pressure water in the pressure pipe 26 makes the flushing cutter head 25 rotate at high speed, and then stirs the sediment in the silted area T. After the sediment is stirred into a water slurry, install a blocking component 1 on the other side of pipeline A.

[0039] The driving wheel frame 11 spreads the three driving wheels 111, holds against the pipe wall and suspends the contracted blocking airbag 12 to a predetermined position. After reaching a position where it cannot be pushed forward continuously, the blocking airbag 12 is inflated to block the pipeline. At the same time, the water slurry formed by the sediment is discharged to the outside of pipeline A along the reflux support member 21. After the operation is completed, the blocking airbag 12 deflates and is pulled back through the recovery cable 13.

[0040] Implementing a pipeline dredging device of the present invention has the following beneficial effects: The pipeline dredging device includes: a blocking component; a step-by-step dredging component, and the step-by-step dredging component includes: a reflux support member and a first airbag, a telescopic airbag and a second airbag respectively sleeved outside the reflux support member. The first airbag, the telescopic airbag and the second airbag are connected in sequence; a flushing cutter head fastened to the end of the second airbag; a pressure pipe communicated with the flushing cutter head, and the pressure pipe is arranged inside the reflux support member. One end of the pressure pipe is connected to the flushing cutter head. Among them: the step-by-step dredging component is pushed into the pipeline from one side where there is a silted area in the pipeline, and the high-pressure water in the pressure pipe is sprayed out by the rotation of the flushing cutter head to stir the sediment; the relative other side of the pipeline where there is a silted area is blocked by the blocking component, and the water slurry formed by the sediment is discharged to the outside of the pipeline along the reflux support member, which can clean the internal siltation of the power jacking pipeline with a relatively small diameter; the structure is simple and reasonable, and it is easy to control the cost.
